[0036] When using the present utility model, when the left filter plate 10 is blocked, first stop adding water to the water inlet hopper 3, and then turn on the first motor 6. The first motor 6 drives the rotation of the screw of the screw pair 7. The left and right nut blocks on the screw pair 7 drive the left and right guide blocks 9 to move left along the guide posts 8 respectively. The guide block 9 drives the filter plate 10 to move left. The left filter plate 10 moves to the left position in the box body 1, and the right filter plate 10 moves to the middle position, realizing the switching of the two filter plates 10. At this time, the right filter plate 10 can normally carry out the filtering work; at the same time, turn on the third motor 23 on the left side. The third motor 23 drives the rotation of the rotating shaft 24 and the scraper 25. The rotation of the scraper 25 scrapes the surface of the left filter plate 10, and clears the impurities into the collection box 5 below, realizing automatic cleaning, facilitating the repeated use of the filter plate 1, saving time and effort, and improving work efficiency;

[0037] When the hot wastewater is poured into the box body 1, turn on the hair dryer 11. The hair dryer 11 blows air into the box body 1, accelerating the interaction between the air in the box body 1 and the outside world, and improving the wastewater cooling speed and the impurity precipitation speed;

[0038] In order to control the water level, first turn on the second motor 16. The second motor 16 drives the rotation of the screw 17. The screw 17 drives the threaded pipe 18 to move up and down. The threaded pipe 18 drives the height limiting plate 19 to move up and down along the guide plate 15 until the height limiting plate 19 is adjusted to the appropriate height (the height of the height limiting plate 19 is the limiting water level height), and then inject water into the box body 1. The floating plate 20 moves up along the guide plate 15 under the buoyancy of the water. When the floating plate 20 moves to contact with the height limiting plate 19, the floating plate 20 reaches the limiting water level height (that is, the water level of the wastewater reaches the limiting height). At this time, the floating plate 20 touches the touch switch 21, and the touch switch 21 controls the buzzer 14 to alarm. At this time, stop injecting water, facilitating the staff to control the water level of the wastewater;

[0039] During the water injection process, a large amount of floating foam is likely to appear. After the foam contacts the moving plate 22 on the water surface, it bursts, avoiding the accumulation of a large amount of foam and ensuring the sedimentation and separation effect of the wastewater.

[0040] After adopting the above structure, the beneficial effects of the present specific embodiment are as follows:

[0041] 1. Through the settings of the collection box 5, the first motor 6, the screw pair 7, the guide posts 8, the guide blocks 9, the filter plate 10, the third motor 23, the rotating shaft 24 and the scraper 25, it is convenient to automatically brush and clean the filter plate 10, saving time and effort, and improving work efficiency;

[0042] 2. Through the setting of the hair dryer 11, the interaction between the air in the box body 1 and the outside world is accelerated, facilitating the acceleration of wastewater heat dissipation and impurity precipitation; through the settings of the connecting plate 12 and the baffle 13, the wastewater is prevented from splashing out of the filter plate 10;

[0043] 3. Through the settings of the buzzer 14, the guide plate 15, the second motor 16, the screw 17, the threaded pipe 18, the height limit plate 19, the floating plate 20 and the touch switch 21, an alarm can be given when the water level reaches the limit position, which is convenient for the staff to control the water level; through the setting of the moving plate 22, it is convenient to break the foam and avoid the accumulation of foam, which affects the precipitation of wastewater.
