[0029] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 : The upper end of the optimal arc column shell 202 is fixedly provided with a feeding port 201, the upper inner walls of the two sides of the optimal arc column shell 202 are fixedly provided with limit strips 203 in an axis-symmetrical manner, the front end and the rear end of the optimal arc column shell 202 are rotatably provided with a rotating shaft 204 between the lower middle positions, the outer diameter of the semi-cylindrical shell 205 is the same as the inner diameter of the optimal arc column shell 202, the rear end of the baffle 206 is fixedly provided on the upper end of the rotating shaft 204, the rear end of the baffle 206 is attached to the inner wall of the rear end of the optimal arc column shell 202, the rear end of the baffle 206 is attached to the inner wall of the front end of the optimal arc column shell 202, and the height of the baffle 206 is the same as the inner diameter of the optimal arc column shell 202;

[0030] The two sides of the rotating shaft 204 are fixedly provided with semi-mesh plates 207 in an axis-symmetrical manner, the rear ends of the two semi-mesh plates 207 are attached to the inner wall of the rear end of the optimal arc column shell 202, the rear ends of the two semi-mesh plates 207 are attached to the inner wall of the front end of the optimal arc column shell 202, the widths of the two semi-mesh plates 207 are the same as the inner diameter of the optimal arc column shell 202, the lower ends of the two semi-mesh plates 207 are respectively and fixedly provided on the upper end of the semi-cylindrical shell 205 near the edge, the lower end of the semi-cylindrical shell 205 is provided with a main discharge port 208, the lower end of the semi-cylindrical shell 205 is provided with auxiliary discharge ports 209 in an axis-symmetrical manner near the two sides, and the outer diameter of the arc-shaped mesh plate 210 is the same as the inner diameter of the semi-cylindrical shell 205;

[0031] Specifically, the solid-liquid mixture enters the optimal arc column shell 202 from the feeding port 201, passes through the filtration of the two semi-mesh plates 207 on the two sides of the baffle 206, the liquid enters the semi-cylindrical shell 205, and the solid waste is stacked on the upper ends of the two semi-mesh plates 207. Due to the fact that the solid-liquid mixture entering the feeding port 201 is not completely uniform, the quality of the solid waste stacked on the two semi-mesh plates 207 is different, similar to a balance, the side with more weight tilts, and due to the arrangement of the limit strips 203, the rotating shaft 204 and the two semi-mesh plates 207 and the semi-cylindrical shell 205 at most rotate by 33 degrees to one side or the other side. When tilting, the solid waste stacked on the two semi-mesh plates 207 slides to the upper ends of the two inclined surfaces 104 under the action of its own gravity;

[0032] The arc-shaped screen plate 210 has a mesh number greater than that of the two half screen plates 207. The once-filtered material entering the semi-cylindrical shell 205 is subjected to secondary filtration through the arc-shaped screen plate 210, and then the contaminated liquid enters the liquid collecting pool 103 through the main drainage port 208 and the two auxiliary drainage ports 209, so that the solid, dregs and contaminated liquid are well separated. When the semi-cylindrical shell 205 is tilted, the auxiliary drainage ports 209 effectively prevent liquid from accumulating at the lowermost end of the semi-cylindrical shell 205 and being difficult to be well discharged into the liquid collecting pool 103 through the main drainage port 208.

[0033] In use, according to actual use needs, the mutually connected inlet 201, optimal arc-cylindrical shell 202, top plate 105, rotating shaft 204, baffle 206 and two half screen plates 207 can be regularly removed to well clean the dregs accumulated on the upper end of the arc-shaped screen plate 210. The optimal arc-cylindrical shell 202 is made of engineering plastic material with good elasticity and toughness, and can be conveniently installed or removed to the upper position of the outer wall of the semi-cylindrical shell 205 on both sides. Alternatively, the mesh number of the two half screen plates 207 can be appropriately increased to effectively reduce the frequency of cleaning the arc-shaped screen plate 210. The arc-shaped screen plate 210 can also not be installed, and the mesh number of the half screen plate 207 can be appropriately increased to separate the large-particle solid and dregs through single filtration, and also to avoid dismounting work.

[0034] Working principle: The solid-liquid mixture enters the optimal arc-cylindrical shell 202 from the inlet 201, and then passes through the two half screen plates 207 on both sides of the baffle 206. The liquid enters the semi-cylindrical shell 205, and the solid waste is accumulated on the upper end of the two half screen plates 207. Since the solid-liquid mixture entering the inlet 201 is not completely uniform, the solid waste accumulated on the two half screen plates 207 has different masses, and the device tilts to the side with more weight, similar to a balance. Due to the arrangement of the limiting strip 203, the rotating shaft 204 and the two half screen plates 207 and the semi-cylindrical shell 205 at most rotate 33 degrees to one side or the other. When tilted, the solid waste accumulated on the two half screen plates 207 slides to the upper end of the two inclined surfaces 104 under the action of its own gravity.

[0035] Secondly, the mesh number of the arc-shaped screen plate 210 is greater than that of the two half screen plates 207. The once-filtered material entering the semi-cylindrical shell 205 is subjected to secondary filtration through the arc-shaped screen plate 210, and then the contaminated liquid enters the liquid collecting pool 103 through the main drainage port 208 and the two auxiliary drainage ports 209, so that the solid, dregs and contaminated liquid are well separated. When the semi-cylindrical shell 205 is tilted, the auxiliary drainage ports 209 effectively prevent liquid from accumulating at the lowermost end of the semi-cylindrical shell 205 and being difficult to be well discharged into the liquid collecting pool 103 through the main drainage port 208.

[0036] Finally, solid waste into the collection box 101 inside and in two slope 104 on the end of the accumulation, by opening two electric gate 102 can be timely and convenient cleaning, liquid into the liquid pool 103 and through the liquid outlet good drainage.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
