The present disclosure claims priority to Chinese patent application No. 201810636943.1, entitled “Cooling Water Circulation System and Method for Using the Same”, filed to the CNIPA on Jun. 20, 2018, the entire content of which is incorporated herein by reference.
The present disclosure relates to, but is not limited to, an apparatus for processing solar assemblies, in particular to a cooling water circulation system and a cooling water circulation control method for a glass edger which is used to solar assemblies.
At present, a glass edger provided in the market needs cooling water to cool the action part during the action process and take away the milled glass powder. The cooling water circulation system of the conventional glass edger only includes a main tank, a water supply line and a return line, and the working process of such system is relatively simple. The whole circulation process can be completed only by supplying water from the main tank to the glass edger and then returning the water flowing out of the glass edger into the main tank through the return line.
Due to the continuous production of glass powder during the operation of the glass edger, the concentration of glass powder suspended in the main tank is continuously increased, and the content of glass powder in the cooling water applied onto the glass edger is also continuously increased, which will affect the film layer of the glass surface. Glass powder is deposited in the main tank and agglomerated, making it difficult to clean. In order to decrease the concentration of glass powder suspended in the main tank, fresh water needs to be continuously replenished during the circulation process and thus the water resource consumption is large.
The following is an overview of the subject matter described in detail herein. This summary is not intended to limit the protection scope of the claims.
An embodiment of this disclosure provides a cooling water circulation system, which includes a main tank configured for supplying water and a first return line configured for returning the water in a glass edger to the main tank. The main tank is in communication with the glass edger through a water supply line. The cooling water circulation system further includes a filtering mechanism configured to filter out and collect the glass powder in the circulating water.
An embodiment of this disclosure also provides a cooling water circulation control method including:
after a glass edger and a cooling water circulation system are initiated, continuously supplying the water from the main tank to the glass edger, and recycling the circulating water returned from the glass edger through a first return line;
collecting the circulating water in a flocculating tank, and introducing a flocculant from a flocculant container into the flocculating tank through an injection line so as to flocculate the glass powder in the circulating water collected in the flocculating tank; and
returning the clear water from an upper part of the flocculating tank to the main tank through a second return line, so as to realize a full cyclic utilization of cooling water and reduce the water resource consumption.

As shown in
In an exemplary embodiment, as shown in
In order to better purify the cooling water, as shown in
The main tank 2, the flocculating tank 3 and the flocculant container 5 may be each communicated with the fresh water inlet 20 through which the main tank 2, the flocculating tank 3 and the flocculant container 5 may be replenished with pure fresh water. In order to cool the circulating water in the main tank 2 and ensure that the water used in the glass edger 1 has a lower temperature, the main tank 2 is further provided with a coolant mixer 31 and a coolant barrel 30 arranged to store coolant. The coolant mixer 31 is provided with a medicament inlet connected to the coolant barrel 30 and a water inlet connected to the fresh water inlet 20. The water and coolant are mixed in the coolant mixer 31 and then discharged into the main tank 2 to act on the circulating water. In addition, an overflow port 32 is provided at the top of the main tank 2 to control the water level in the main tank 2.
The main tank 2 may be provided with a first stirring device 27, which is driven by a first stirring motor 28 to stir water in the main tank 2 so as to prevent glass powder from quickly settling and agglomerating in the main tank 2. The flocculating tank 3 is internally provided with a second stirring device 23, which is driven by a second stirring motor 24 to stir the water in the flocculating tank 3 so as to promote rapid flocculation. The flocculant container 5 is internally provided with a third stirring device 25, which is driven by a third stirring motor 26 to stir the water and flocculant in the flocculant container 5 so as to fully mix them.
In order to facilitate the control of the whole circulation process, it is possible that the cooling water circulation system is further provided with a controller. The controller is connected with the metering pump 22, the first lift pump 18, the second lift pump 19, the valve 17, the water supply pump 15, the return pump 16, the first stirring motor 28 and other devices, respectively, and is configured to control the opening and closing of the pumps, the stirring time, the stirring interval, the dosing interval, the dosing time, the flocculation time and the like so as to realize an automatic control.
The above-mentioned cooling water circulation system creates a closed-loop circulation process. Before the glass edger 1 and the cooling water circulation system are operated, it is needed to inject water into the main tank 2, the flocculating tank 3 and the flocculant container 5, and add medicament appropriately according to the flocculant concentration and coolant concentration to complete the initial injection of water and medicament. After the glass edger 1 and the cooling water circulation system are initiated, the main tank 2 is required to continuously supply water to the glass edger 1 through the water supply line 8, and the flow rate of the cooling water can be adjusted by setting a return valve. After passing through the glass edger 1, the cooling water is heated up and recycled to the separation barrel 33 by the water-gas separator 7. The air is discharged through the silencer 35 located above, the returned water converges to the water reservoir 34 under the action of gravity and is recycled to the main tank 2 by the return pump 16. Subsequently, the first stirring device 27 is operated, the glass powder in the circulating water in the main tank 2 is settled, the water in the main tank 2 is continuously lifted to the flocculating tank 3, and the flocculant container 5 injects flocculant into the flocculating tank 3. The second return line 11 continuously returns clear water from the upper part of the flocculating tank 3 to the main tank 2, and the glass powder is combined with the flocculant to produce large polymer, and precipitate quickly and flocculate fully. The second stirring device 23 stirs periodically. After the flocculation is performed for a predetermined time, the valve 17 is opened, the precipitate and part of the water enter the glass powder collector 4. After filtration, the precipitate is completely retained in the powder collecting bag of the glass powder collector 4, and the separated water is re-injected into the flocculating tank 3 and returned to the main tank 2 through the second return line 11, so as to complete the whole circulation process. During the circulation process, the medicament can be periodically injected from the flocculant container 5 into the flocculating tank 2 by the metering pump 22. When the flocculating tank 3 continuously purifies the water in the main tank 2, the first return line 9 will still carry the circulating water with glass powder, thus a small amount of glass powder still exists in the circulating water just conveyed into the water supply line 8. The circulating water flowing out of the main tank 2 can be filtered by a filter 6 for a second time to completely remove the glass powder. In addition, according to the water levels in the main tank 2, flocculating tank 3 and flocculant container 5, the controller can appropriately replenish water through the fresh water inlet 20.
The amount of water consumed by the cooling water circulation system of this embodiment is only 2% of that consumed by the original system, which can greatly reduce the water resource consumption, and the collection during the whole circulation process is convenient, thus the manpower is saved and the environment is protected.

After the glass edger 1 and the cooling water circulation system are initiated and when the cyclic purification is started, the main tank 2 supplies water to the glass edger 1. After passing through the glass edger 1, the cooling water is recycled to the flocculating tank 3 by the return pump 16, and the flocculant is injected from the flocculant container 5 into the flocculating tank 3. Subsequently, the clear water from the upper part of the flocculating tank 3 is continuously returned to the main tank 2 through the second return line 11. The glass powder is combined with the flocculant to produce large polymer and precipitate rapidly. The glass powder is collected by the glass powder collector 4, while the water separated by the glass powder collector 4 is re-injected into the flocculating tank 3 and returned to the main tank 2 through the second return line 11 to ensure that the cooling water in the main tank 2 has a low glass powder concentration, thus completing the whole circulation process.
Since the water is returned to the flocculating tank 3, the outflow pipe 10 at the bottom of the main tank may not be provided at the bottom of the main tank 2, or the first stirring device 27 may not be provided inside the main tank 2. The apparatus structure is simplified and is suitable for cooling water circulation with a small or medium flow rate.
The cooling water circulation system of the present disclosure can reduce the content of the glass powder in the circulating water and improve the quality of glass products. The flocculating tank and the glass powder collector of the present disclosure can automatically collect glass powder, the collection process is convenient and environment-friendly, and deposition and agglomeration of glass powder in the main tank are avoided. The cooling water circulation system of the present disclosure does not need to continuously replenish fresh water to reduce the content of glass powder, thereby reducing the cooling water consumption. The first stirring device of the present disclosure can prevent glass powder from rapidly precipitating and agglomerating in the main tank, and the second stirring device can promote the flocculation process.
An embodiment of this disclosure also provides a cooling water circulation control method including:
after a glass edger and a cooling water circulation system are initiated, continuously supplying the water from a main tank to the glass edger, and recycling the circulating water returned from the glass edger through a first return line;
collecting the circulating water in a flocculating tank, and introducing a flocculant from a flocculant container into the flocculating tank through an injection line so as to flocculate the glass powder in the circulating water collected in the flocculating tank; and
returning the clear water from an upper part of the flocculating tank to the main tank through a second return line.
With the cooling water circulation control method, the glass powder in the circulating water collected in the flocculating tank can be flocculated and agglomerated to form precipitate and thus settle at the bottom of the flocculating tank, thereby reducing the content of glass powder in the circulating water.
After the flocculant in the flocculant container is introduced into the flocculating tank, the method further includes:
after flocculating for a predetermined time, opening the valve to allow the precipitate formed by flocculation to enter the glass powder collector along with the circulating water, and conveying the circulating water separated from the glass powder collector back into the flocculating tank through a third return line so as to separate the precipitate from the flocculating tank in time.
In an exemplary embodiment, collecting the circulating water in the flocculating tank includes: directly injecting the circulating water returned through the first return line into the main tank, and introducing the circulating water collected in the main tank into the flocculating tank through the outflow pipe at the bottom.
In another exemplary embodiment, collecting the circulating water in the flocculating tank includes: directly injecting the circulating water returned through the first return line into the flocculating tank for collection.
