[0028] Working principle: When in use, first pour the sewage to be treated into the separation tank 1 from the water inlet 2. After the water flows through the filter plate body 10, the dirt and sludge will be trapped on the upper surface of the filter plate body 10. Pull out the sealing plug 3 to allow the liquid water to flow out from the water outlet at the bottom of the separation tank 1. When it is necessary to clean the dirt on the surface of the filter plate body 10, the mains power can be connected to power the device, and the controller 4 is used to start the motor 5. The motor 5 is a stepping motor with strong controllability and sensitive response. The output end of the motor 5 drives the screw rod 11 to rotate, and the screw rod 11 drives the baffle plate 12 and the movable plate 13 to slide synchronously along their outer surfaces. Under the action of the limit rod 15, the baffle plate 12 and the movable plate 13 can move more smoothly, and the scraper 18 follows the baffle plate 12 and the movable plate 13 to move. The central shaft 19 drives the gear 16 to move synchronously with the scraper 18.

At the same time, the electric door 17 is opened by the controller 4. After the dirt is pushed from the liquid separation box 1 to the processing box 6 by the barrier plate 12, the heating wire 21 is turned on by the controller 4. The heating wire 21 converts electrical energy into thermal energy. The specific conversion steps are prior art and will not be elaborated on here. The heat of the heating wire 21 is transferred to the processing box 6 through the channel groove 9 to dry the wet dirt in the processing box 6. After drying, the cylinder 22 can be turned on by the controller 4. The cylinder 22 is a double-acting cylinder with controllable stroke and bidirectional movement. The piston end of the cylinder 22 drives the pressing plate 8 to press down, so that the dry dirt is squeezed into shape. Finally, the support plate 7 is pulled out and the dirt is taken out for processing. For the clarity of the attached figure, the cross-sectional state of the processing box 6 is shown, and the front of the processing box 6 can be equipped with a suitable door. The above is the entire working principle of the utility model.
