1. Field of the Invention
The present invention relates to a wastewater purifying device and, more particularly, to a continuous type wastewater purifying device for continuously purifying wastewater.
2. Description of the Related Art
To reuse water resources, wastewater recycling apparatuses have been proposed and are available in the market to treat livelihood sewage or rainwater for effectively reducing waste of water resources.
The wastewater is conveyed from the wastewater inlet 911 to the vertical condensing portion 92. In the vertical condensing portion 92, the wastewater flows through a heat exchange plate 94 and is conveyed by an internal pipe to a wastewater tank 95. The wastewater in the wastewater tank 95 is pressurized and conveyed by a pump to the heating portion 913 and is heated and evaporated by the sunlight into wastewater vapor that flows along the sloping heating portion 913. The wastewater vapor condenses into water drops that fall into the vertical condensing portion 92. Condensed purified water accumulates in the storage portion 93 and can be used via the purified water overflow port 912.
Although the solar heating device 9 can purify wastewater, the wastewater must be drawn by additional power, causing energy consumption during pressurization of the pump. In some occasions, wastewater can not be supplied in time and, thus causes limitation to the wastewater purification efficiency of the solar heating device 9. Furthermore, the solar heating device 9 is integral and occupies a considerable space. Namely, the solar heating device 9 can not be rearranged in response to different situations, providing limited utility. Further, the costs will be significantly increased and, thus impractical if several sets of solar heating devices 9 are used with an intension of increasing the wastewater purification efficiency. As a result, the wastewater purification efficiency can not be increased.

A continuous type wastewater purifying device according to the present invention can be used to recycle and purify various wastewater resources, such as household water and rainwater. The purified water obtained after treatment can be used for various purposes not for cleaning human bodies, such as for watering plants, household cleaning, etc.
With reference to
The wastewater tank 1 can be any type of water container and is preferably mounted on or beside a building for collecting wastewater including but not limited to the household water in the building and rainwater falling on or beside the building. In the form shown, the wastewater tank 1 defines a predetermined level 11 that is the highest level of the wastewater received in the wastewater tank 1. The predetermined level 11 can be varied according to the amount of wastewater received in the wastewater tank 1. Preferably, the wastewater tank 1 includes a level adjusting member 12 in the form shown including a float 13 and a float-controllable switch 14 coupled to the float 13. In a case that the level of the wastewater in the wastewater tank 1 reaches the predetermined level 11, the buoyancy of float 13 shuts down the float-controllable switch 14 to stop feeding of external water into the wastewater tank 1, preventing overflow of wastewater while receiving sufficient amount of wastewater. Note that other types of the level adjusting member 12 can be used.
The wastewater tank 1 can be connected to a raw water storage tank by a pipe. Impurities carried by the wastewater can deposit in the raw water storage tank. The raw water storage tank can be a tower comprised of a plurality of detachable layers.

After evaporation of the wastewater, wastewater is supplied from the wastewater tank 1 into the heat conduction pipes 33 with the level of wastewater in each heat conduction pipe 33 remaining the same as that of wastewater in the wastewater tank 1. After repeated operations, the water inlet valve V1 is closed, and the water outlet valve V2 is opened, so as to discharge the wastewater in the heat conduction pipes 33 for cleaning and reuse of the heat conduction pipes 33.
In view of the foregoing, the main feature of the continuous type wastewater purifying device according to the present invention is that by locating the outlet end 331 of each heat conduction pipe 33 connected to the purified water pipe 32 at a position higher than the predetermined level 11 of the wastewater tank 1, the inclination angle θ of each heat conduction pipe 33 can be adjusted according to the magnitude of the predetermined level 11. Thus, no extra energy consumption is required to convey the wastewater from the wastewater tank 1 into the heat conduction pipe 33, maintaining continuous cycling of water while avoiding overflow from the heat conduction pipes 33. As a result, the continuous type wastewater purifying device according to the present invention not only saves extra power consumption but improves the wastewater purification effect through continuous wastewater supply. Furthermore, the continuous type wastewater purifying device according to the present invention can be rearranged according to differing needs at different locations through the use of a single or multiple heat conduction pipes 33, maintaining an appropriate amount of purified wastewater. The utility is enhanced while allowing easy assembly and detachment of the heat conduction pipes 33 according to needs, reducing the time and costs during the use.
