1. Technical Field
The present disclosure generally relates to filtering devices, and particularly to an air filtering device in production departments.
2. Description of the Related Art
Air in production departments, especially in metal manufacturing departments, contains much dust. The dust contaminates the working environment, and affects usage lifetime of machines and health of workers adversely. A plurality of fans connected to extracting pipelines is positioned to directly draw the air out. However, the efficiency is relatively low. In addition, the extracting pipelines or ports need frequent cleaning
Therefore, there is room for improvement within the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The treatment house 30 includes a base body 31, a dividing board 33 (as shown in
The dividing board 33 protrudes substantially perpendicularly from the top wall 311 adjacent to the air outlet 307. The dividing board 33 is connected substantially perpendicularly with the second sidewall 315 and the fourth sidewall 319, and is located above the tank body 11. The dividing board 33 divides the treatment house 30 into the first treatment room 301 and the second treatment room 303. The air intake 305, the monitor windows 310 of the second and third sidewall 315, 317 are positioned in the first treatment room 301. The air outlet 307 and the monitor windows 310 of the first sidewall 313 are positioned in the second treatment room 303. A zigzag shaped guide end 331 is formed at an end of the dividing board 33 away from the top wall 311 to guide the flow and diffusion of the exhaust air in the treatment house 30.
A plurality of baffles 35 is positioned in the first and second treatment rooms 301, 303. In the illustrated embodiment, there is a first baffle 351, a second baffle 353, and a third baffle 355. The first baffle 351 is mounted on the first sidewall 313 above the air intake 305 and is received in the first treatment room 301. The second baffle 353 is positioned on the dividing board 33. The third baffle 355 is positioned on the third sidewall 317 above the second baffle 353. Both the second baffles 353, and the third baffles 355 are received in the second treatment room 303. The first, second, and third baffles 351, 353, 355 are inclined toward the tank body 11, for guiding droplets and the waste flow into the tank body 11. In other embodiments, the number and the installation positions of the baffles 35 can be positioned as needed.
The pump 50 is mounted on an external wall of the tank body 11 above the exhaust water pipe 11 and under the fourth sidewall 319. The pump 50 includes a container 51 and a pump body 53 mounted on the container 51. The container 51 is mounted on the external wall of the tank body 11 above the exhaust water pipe 11. The container 51 is connected with and communicates with the pump body 53.
The spraying member 70 is mounted on one internal sidewall of the second treatment room 303 above the third baffle 355, and connects with and communicates with the pump body 53. In the illustrated embodiment, the spraying member 70 is a spray pipe. A first end of the spraying member 70 is mounted on the fourth sidewall 319, and connects and communicates with the pump body 53 (not shown). The pump body 53 draws water from the container 51 to the spraying member 70.
The filtering device 100 further includes a water supplying tank 90. The water supplying tank 90 is positioned on an external sidewall of the tank body 11 opposite to the pump 50, such that the water supplying tank 90 is connecting and communicating with the tank body 11. A float level switch (not shown) is positioned in the water supplying tank 90 to detect the water level, such that the water supplying tank 90 supplies water to the tank body 11 when the water level of the water supplying tank 90 is lower than a preset level. The filtering device 100 can further include a filter 101. The filter 101 is connected between the exhaust water pipe 11 and the water supplying tank 90 to filtrate exhaust water for recycling water.
In assembly, the pump 50 is mounted on the external side wall of the tank body 11. The spraying member 70 is positioned in the second treatment room 303. The treatment house 30 is covered on the tank body 30. The spraying member 70 connects with and communicates with the pump 50. The fan 80 is positioned on the top wall 311 and faces the air outlet 307.
In use, water is stored in the tank body 11 and the water supplying tank 90. The dividing board 33 is positioned above the water. A gap (not labeled) is formed between the guide end 331 and water. The fan 80 and the pump 50 start, the exhaust gas enters the first treatment room 301, and strong adsorbing force is produced by the fan 80 and makes water in the tank body 11 spray to form mist. Dust or other contaminants in the air contact with and are absorbed by the mist. Water absorbed with dust remains in the first baffle 351 and sidewalls of the first treatment room 301. In addition, because of adsorption force produced by the fan 80, the exhaust air also enters the second treatment room 303. The spraying member 70 sprays water to form a water curtain to purify air. Dust and other contaminants in the air contact with and are absorbed by the water curtain.
The treatment house 30 is divided into the first treatment room 301 and the second treatment room 303 by the dividing board 33. The fan 80 generates water mist to purify the exhaust air, and the spraying member 70 sprays water to form a water curtain to purify the exhaust air. Because air is purified in the first and second treatment rooms 301, 303, which are closed, the efficiency is greatly improved. Emission remaining in the exhaust pipelines and exhaust port is decreased.
In other embodiments, the pump 50 and the spraying member 70 can be omitted, in other words, the filtering device 100 includes a tank 10, a treatment house 30, and a fan 80. The treatment house 30 includes a base body 31 and a dividing board 33. The base body 31 covers the tank 10. The dividing board 33 divides the treatment house 30 into the first treatment room 301 and the second treatment room 303. The guide end 331 is positioned at one end of the dividing board 33 adjacent to the tank 10. The air intake 305 is positioned on the first treatment room 30, and the air outlet 307 is positioned on the second treatment room 303. The fan 80 is positioned adjacent to the air outlet 307 and faces the air outlet 307.
While the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the disclosure, as defined by the appended claims.
