[0002] In the sewage treatment system, the sewage filter tank is mainly used to filter the sewage, thereby reducing the large impurities in the sewage. However, after a long period of treatment, a large amount of impurities will adhere to the surface of the screen in the sewage filter tank. The presence of these impurities will reduce the flow rate of the sewage, thereby reducing the sewage treatment efficiency. Therefore, the screen needs to be cleaned regularly. In the prior art, the cleaning of the screen in the sewage filter tank is mostly performed manually, which is time-consuming and labor-intensive. Utility Model Content

When the linear motion module 200 drives the moving platform 201 to move linearly, the moving platform 201 can drive the cleaning platform 202 to move linearly, so that the cleaning platform 202 can remove the impurities attached to the surface of the screen 101. At the same time, the moving platform 201 can also drive the cleaning brush roller 203 to move linearly. At this time, under the action of the gear 204 and the rack 205, the cleaning brush roller 203 can rotate. In this way, the rotating cleaning brush roller 203 can clean the stubborn impurities on the surface of the screen 101, thereby ensuring that the cleaning mechanism has an excellent cleaning effect on the screen 101;

[0018] Furthermore, the linear motion module 200 further includes a motor 206, a lead screw 207, and a sliding column 208. The sliding column 208 is fixedly connected to one side of the screen 101, and the sliding column 208 is slidably connected to the moving platform 201. The lead screw 207 is threadedly connected to the moving platform 201. The motor 206 is fixedly connected to the filter tank 100. The motor 206 is connected to the lead screw 207 by power. The lead screw 207 sleeve is provided outside the lead screw 207, so that the motor 206 can drive the lead screw 207 to rotate, so that the moving platform 201 generates a linear motion on the sliding column 208, and the lead screw 207 sleeve can prevent impurities from adhering to the lead screw 207 and affecting the normal operation of the lead screw 207.

[0019] At the same time, a top frame 210 is fixedly connected to the top of the screen 101, a bottom frame 211 is fixedly connected to the bottom of the screen 101, the top end of the sliding column 208 is fixedly connected to the top frame 210, the bottom end of the sliding column 208 is fixedly connected to the bottom frame 211, the top end of the lead screw 207 is rotatably connected to the top frame 210, and the bottom end of the lead screw 207 is rotatably connected to the bottom frame 211, so that the installation of the sliding column 208 and the stable rotation of the lead screw 207 can be achieved;

[0020] Of course, in order to discharge the impurities cleaned by the cleaning mechanism to the outside, a slag discharge port 102 is provided at the bottom of the filter tank 100 to match the cleaning mechanism, and a closing mechanism is provided at the slag discharge port 102. The closing mechanism includes a traction component 300, a slide rail 301 and a sealing platform 302. The filter tank 100 is fixedly connected with slide rails 301 on both sides of the slag discharge port 102, and the sealing platform 302 is slidably connected to the slide rail 301. The traction component 300 is fixedly connected to the filter tank 100, and the traction component 300 is fixedly connected to the sealing platform 302. In this way, the sealing platform 302 can be pulled by the traction component 300 to perform linear motion, so that the sealing platform 302 opens or closes the slag discharge port 102. When the sealing platform 302 moves to open the slag discharge port 102, the impurities cleaned by the cleaning mechanism can be discharged from the slag discharge port 102. When the sealing platform 302 closes the slag discharge port 102, it can prevent the sewage from flowing out during filtration. The traction component 300 here can be an electric telescopic cylinder.

[0021] Further optimized, the closing mechanism also includes a slag discharge component, which includes a slag collecting box 303, a slag discharge pipe 304 and a valve 305. The bottom of the filter pool 100 is fixedly connected with a slag collecting box 303 corresponding to the slag discharge port 102. The slag collecting box 303 is matched with the sealing platform 302 and is provided with a movement port 306, so that the traction component 300 can drive the sealing platform 302 to move from the movement port 306. The slag collecting box 303 is fixedly connected with a slag discharge pipe 304, and the slag discharge pipe 304 is fixedly connected with a valve 305. The sewage in the filter pool 100 can enter the slag collecting box 303 and be collected. Then the traction component 300 drives the sealing platform 302 to seal the slag discharge port 102. When the screen 101 needs to be cleaned, The cleaning mechanism cleans the surface of the screen 101 according to the above principle, and the cleaned impurities enter the slag collecting box 303 at the bottom through the slag discharge port 102. After opening the valve 305, the sewage and impurities in the slag collecting box 303 can be discharged to the outside through the slag discharge pipe 304. With this structural design, after the cleaning mechanism cleans the screen 101 multiple times, the impurities cleaned each time are collected in the slag collecting box 303, and finally a large amount of impurities are discharged at one time, thereby reducing the operation frequency. The sealing platform 302 can not only seal the slag discharge port 102, but also seal the slag collecting box 303, thereby preventing the collected impurities from entering the filter tank 100 again, causing the impurities in the filter tank 100 to increase and affect the filtering effect.
