A through groove 86 is opened inside the sliding sleeve 85. The rotating shaft 84 is slidably connected inside the through groove 86. By designing the through groove 86, the mechanism can... The rotating shaft 84 can slide inside the through groove 86. The bottom of the sliding sleeve 85 is fixedly connected to a push-pull rod 87. The push-pull rod 87 is slidably connected to the fixed seat 81 and the cover plate 5 respectively. The push-pull rod 87 is fixedly connected to the connecting rod 10.

The guide rod 89 is slidably sleeved inside the guide block 88. The guide rod 89 is fixedly connected to the fixed seat 81. By designing the guide rod 89, the movement of the guide block 88 can be guided. By designing the shaking mechanism 8, the support frame 6 and the filter screen 7 can be shaken.

[0024] Please see Figure 1 , Figure 2 , Figure 4The cleaning mechanism 9 includes a fixed rod 91, which is fixedly connected inside the support frame 6. A spring 92 is provided on the outside of the fixed rod 91.

[0025] The specific implementation process of this utility model is as follows: When in use, under the action of tank 1, the halogenated hydrocarbon wastewater can be stored for subsequent recycling and use.

[0026] When wastewater enters the tank 1, it is filtered by the support frame 6 and the filter screen 7, removing particulate impurities and preventing blockages in the conveying pipeline or impacts on subsequent recycling due to excessive impurities. During filtration, the motor 82 operates simultaneously, driving the turntable 83 to rotate. The turntable 83 rotates the shaft 84, which in turn rotates along the sliding sleeve 85.

When the scraper ring 97 is pulled upward, the scraper ring 97 drives the connecting block 95 to move upward. The connecting block 95 and the retaining ball 94 slide relative to each other. The arc surface of the retaining groove 96 inside the connecting block 95 will squeeze the retaining ball 94, and the retaining ball 94 will roll outward. The retaining ball 94 drives the slider 93 to slide along the fixed rod 91. The slider 93 will squeeze the spring 92, and finally the retaining ball 94 can be separated from the retaining groove 96. Then the connecting block 95 can be pulled out from the inside of the support frame 6 to disassemble the scraper ring 97, which is convenient for maintenance of the scraper ring 97 after use.
