[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-Figure 5As shown, a filter press for treating chemical wastewater comprises a box body 101, a drain pipe 102 is threadedly connected to the bottom of the box body 101, a valve is arranged on the drain pipe 102, a maintenance groove 103 is opened at the front end of the box body 101, a water inlet mechanism 2 is arranged on one side of the top of the box body 101, an auxiliary mechanism 5 is arranged in the water inlet mechanism 2, a power mechanism 3 is arranged on the top of the box body 101, a pressing mechanism 4 is arranged on the top of the box body 101, the power mechanism 3 is located on one side of the pressing mechanism 4, a plurality of filtering mechanisms 6 are arranged in the box body 101, an opening and closing mechanism 7 is arranged in the maintenance groove 103, the power mechanism 3 comprises a fixing plate 301, and the fixing plate 301 is connected by a plurality of filtering mechanisms 6. The screws are connected to the top of the box body 101, and the rear end of the fixing plate 301 is connected to the motor 302 by bolts. The output shaft of the motor 302 is connected to the cam 303 by a key, and the front end of the cam 303 is connected to the connecting block 304 by screws. The connecting block 304 is located at the end away from the output shaft of the motor 302. The connecting block 304 is rotatably connected to the transmission rod 305. The motor 302 drives the cam 303 to rotate, and the cam 303 drives the transmission rod 305 to move. The limit block 401 limits the pressure rod 402 so that it can only move up and down. The transmission rod 305 drives the pressure rod 402 to move up and down, so that the pressure plate 404 moves in the box body 101.

[0025] The pressing mechanism 4 includes a limit block 401, which is connected to the top of the box body 101 by bolts, a leak-proof ring is arranged inside the limit block 401, the limit block 401 is slidably connected to a pressure rod 402, the top of the pressure rod 402 is connected to a rotating block 403 by screws, the rotating block 403 is rotatably connected to the transmission rod 305, the bottom of the pressure rod 402 is connected to a pressure plate 404 by screws, and the pressure plate 404 is located inside the box body 101.

[0026] The water inlet mechanism 2 includes a front-to-back symmetrical control block 201 . The control block 201 is connected to one side of the top of the box body 101 by bolts. A water inlet pipe 202 is threadedly connected to the top of the control block 201 .

[0027] The auxiliary mechanism 5 includes a silicone ring 501, which is fixedly connected to the bottom of the water inlet pipe 202. A plurality of springs 502 are welded on the top of the water inlet pipe 202. A light ball 503 is welded on the bottom of the spring 502. The light ball 503 contacts the silicone ring 501. When the transmission rod 305 drives the pressure rod 402 to press down, the light ball 503 is pressed against the silicone ring 501 due to the pressure. Then, when the transmission rod 305 drives the pressure rod 402 to rise, the light ball 503 is separated from the silicone ring 501 due to the change in internal pressure. The spring 502 is deformed so that the silicone ring 501 is not in contact with the light ball 503, so that water enters the box 101 from the water inlet pipe 202. Then, the spring 502 recovers its deformation to reset the light ball 503. The motor 302 drives the transmission rod 305 to move back and forth, which automatically controls the water inlet and avoids damage caused by clogging of a large amount of water inlet at one time.

The top of the water inlet pipe 202 is connected to the water pipe. The sliding groove 602 can be replaced as needed, and then the box door 701 is closed. Due to the provision of the sealing strip 703, a closed space is formed inside the box body 101.

[0030] Working principle: When in use, connect the top of the water inlet pipe 202 to the water pipe, replace the sliding groove 602 as needed, and then close the box door 701. Due to the sealing strip 703, a closed space is formed inside the box body 101. Then the motor 302 drives the cam 303 to rotate, and the cam 303 drives the transmission rod 305 to move. The limit block 401 limits the pressure rod 402 so that it can only move up and down. The transmission rod 305 drives the pressure rod 402 to move up and down, so that the pressure plate 404 moves in the box body 101. When the transmission rod 305 drives the pressure rod 40 When pressing down, the light ball 503 is pressed against the silicone ring 501 due to the pressure, and then the transmission rod 305 drives the pressure rod 402 to rise. Due to the change in internal pressure, the light ball 503 is separated from the silicone ring 501, and the spring 502 is deformed, so that the silicone ring 501 and the light ball 503 are not in contact, so that water enters the box body 101 from the water inlet pipe 202. Then the spring 502 recovers its deformation to reset the light ball 503, and the motor 302 drives the transmission rod 305 to reciprocate, which will automatically control the water inlet and avoid damage caused by clogging due to a large amount of water inlet.
