[0029] The bracket 110 is used to install the functional tube 120 to ensure the stability of the functional tube 120. The functional tube 120 is used to install the rotating seat 130 to ensure the stability of the rotating seat 130 when rotating. The functional tube 120 includes a tube body 121 that passes through the bracket 110, a partition 122 that is fixed on the inner wall of the tube body 121 and divides the inner cavity of the tube body 121 into two cavities, a liquid outlet pipe 123 installed on one side of the tube body 121 and connected to the cavity above the partition 122 in the tube body 121, and an air inlet pipe 124 installed on one side of the tube body 121 and connected to the cavity below the partition 122 in the tube body 121. Both ends of the tube body 121 are closed, and the partition 122 divides the inner cavity of the tube body 121 into two upper and lower cavities. The inner cavity of the tube body 121 is located above the partition 122. The cavity is used to send out the filtered sewage, the cavity in the tube body 121 located below the partition 122 is used for high-pressure air circulation, the liquid outlet pipe 123 is connected with the cavity in the tube body 121 located above the partition 122, and is used to send out the filtered sewage, the air inlet pipe 124 is connected with the cavity in the tube body 121 located below the partition 122, and is used to send in high-pressure gas, and rectangular holes 1211 are opened on the upper surface of the tube body 121 located in the inner cavity of the rotating seat 130, so that the sewage filtered by the filter plate 140 can enter the cavity in the tube body 121 above the partition 122, and spray holes 1212 are opened in an array on the lower surface of the tube body 121 located in the inner cavity of the rotating seat 130, so that the high-pressure air can be sprayed out through the spray holes 1212 to clean the sludge on the filter plate 140.

[0030] The rotating seat 130 is rotatably sleeved on the outside of the tube body 121 for installing the filter plate 140 and driving the filter plate 140 to rotate and switch. V-shaped grooves 131 are opened on both sides of the rotating seat 130. The filter plate 140 is fixed to the inner wall of the V-shaped groove 131 by bolts to facilitate the replacement of the filter plate 140.

[0031] The driving member 160 is used to drive the rotating seat 130 to rotate, and includes a motor 161 fixed on the bracket 110 and a gear 162 fixed on the shaft of the motor 161. The gear 162 and the gear ring 150 are meshed with each other, so that when the motor 161 rotates, it can drive the gear 162 to rotate. The rotation of the gear 162 drives the gear ring 150 to rotate. The rotation of the gear ring 150 drives the rotating seat 130 to rotate, thereby realizing the switching of the filter plates 140 on both sides of the rotating seat 130.

[0032] The filter press module 200 is used to squeeze sewage so that it is filtered through the filter plate 140, and includes a slider 210 slidably arranged on the bracket 110, a shell 220 whose two ends are fixed to the slider 210, a compression member 230 installed at the top of the shell 220 and extending into the inner cavity of the shell 220, a liquid inlet member 240 installed on one side of the shell 220 and connected to the inner cavity of the shell 220, and a second electric telescopic rod 250 installed on the bracket 110 and fixedly connected to the slider 210.

[0033] The slider 210 is used to install the shell 220 and limit the movement of the shell 220. The shell 220 is pressed against the end of the filter plate 140 to form a sealed space for convenient entry of sewage. The compression member 230 is used to compress the sewage so that the sewage is filtered through the filter plate 140. The compression member 230 includes a first electric telescopic rod 231 fixed to the top of the shell 220 and extending into the inner cavity of the shell 220, and a pressing plate 232 arranged in the inner cavity of the shell 220 and fixedly connected to the first electric telescopic rod 231. The first electric telescopic rod 231 is started to drive the pressing plate 232 to move up and down, thereby squeezing the sewage and filtering the sewage through the filter plate 140.

[0034] The liquid inlet part 240 is used to deliver sewage into the inner cavity of the shell 220, and includes a liquid inlet pipe installed on one side of the shell 220 and connected to the inner cavity of the shell 220, and an electric valve 242 installed on the liquid inlet pipe. The liquid inlet pipe is used to deliver sewage, and the electric valve 242 is used to control the opening and closing of the liquid inlet pipe.

[0035] The end of the second electric telescopic rod 250 is fixedly connected to the slider 210 and is used to control the slider 210 to move up and down, that is, to drive the housing 220 to move up and down.

[0036] The working principle and use process of the utility model are as follows: when in use, chemical sewage is sent into the inner cavity of the shell 220 through the liquid inlet pipe, and then the electric valve 242 is closed. At this time, the first electric telescopic rod 231 is started, driving the pressure plate 232 to press down. The pressure plate 232 is pressed down to make the sewage pass through the filter plate 140 under the action of pressure, and the impurities and sludge in the sewage are filtered by the filter plate 140. The clean water follows the V-groove 131 on the rotating seat 130 and passes through the rectangular hole 1211 on the tube body 121, enters the cavity above the partition 122 in the tube body 121, and is finally sent out through the liquid outlet pipe 123. When there is a lot of sludge on the filter plate 140, the second electric telescopic rod 250 is started, and the shell 220 is driven to move up through the slider 210. At the same time, the motor 161 is started, driving the gear 162 to rotate. The gear 162 rotates to drive the gear ring 150 to rotate, and the gear ring 150 rotates to drive the rotating seat 130 to rotate. The rotating seat 130 rotates to switch the filter plates 140 on both sides, and the clean filter plates 140 face the shell 220, and the filter plates 140 with more silt are lowered toward the rotating seat 130. At this time, the second electric telescopic rod 250 drives the shell 220 to move downward through the slider 210, so that the shell 220 is pressed tightly on the clean filter plate 140, and the chemical wastewater can be filtered again. At the same time, the high-pressure airflow is sent into the cavity below the partition 122 in the tube body 121 through the air inlet pipe 124, and is sprayed out through the spray hole 1212. The silt attached to the filter plate 140 is washed away by the high-speed airflow, thereby realizing automatic cleaning of the filter plate 140, and the alternating cycle can be performed.
