[0013] In the figure: 1 separation box, 2 cover plate, 3 stirring shaft, 4 separation barrel, 5 filter hole, 6 positioning plate, 7 telescopic cylinder, 8 fixing plate, 9 baffle, 10 cleaning rod. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 As shown, a blocking-proof solid-liquid separator includes a separation box 1, a cover plate 2 is provided on the separation box, a notch is provided in the middle of the cover plate for the stirring shaft 3 to pass through, the stirring shaft extends into the separation box and is connected to the separation barrel 4, and a plurality of groups of vertically arranged multiple filter holes 5 are provided on the barrel wall of the separation barrel. A positioning plate 5 is also provided under the cover plate, and the positioning plate is arranged concentrically with the notch. The stirring shaft and the positioning plate can be connected through a bearing to further improve the stability of the stirring shaft arrangement. The positioning plate is connected to a vertically arranged fixed plate 8 extending into the separation barrel through a telescopic cylinder 6 arranged horizontally. After the telescopic cylinder is extended, the fixed plate contacts the inner side of the barrel wall of the separation barrel. Preferably, two groups of telescopic cylinders and fixed plates are provided.

[0016] Furthermore, the upper end of the stirring shaft is connected to the driving motor, and the driving motor and the cover plate are integrally connected to the external frame by sliding up and down, so as to facilitate the discharge of solid debris after solid-liquid separation.

[0017] Furthermore, an auxiliary cleaning structure is provided on the inner side wall of the separation box, and the auxiliary cleaning structure includes a plurality of cleaning rods 10 arranged horizontally in the vertical direction, the cleaning rods are slidably connected to the separation box, and the cleaning rods slide through the filter holes. The horizontal cleaning rods arranged in the vertical direction are preferably set to four groups, which are evenly arranged in the circumferential direction.

[0018] An L-shaped baffle 9 is also provided on the inner wall of the separation box, and the cleaning rod passes through the baffle. The stability of the cleaning rod layout is improved. A sealing structure such as a sealing gasket is provided where the cleaning rod passes through the wall of the separation barrel. The sliding connection of the cleaning rod can be achieved by controlling the telescopic cylinder structure. On the other hand, the setting of the baffle also reduces the impact of the sewage thrown out by the centrifuge on the sealing structure, reducing the possibility of sewage overflow.

[0019] The working principle of the utility model is as follows: sewage enters the separation barrel from the feed port on the cover plate, and then the separation barrel rotates centrifugally to achieve solid-liquid separation. During the separation process, the telescopic cylinder works intermittently, and the fixed plate abuts against the side wall of the separation barrel to achieve scraping to prevent debris from blocking the filter holes. During the separation process, the liquid at the separation point is directly discharged from the lower end; after shutdown, the cleaning rod works, and the separation barrel rotates in the gap to achieve further cleaning of the filter holes of the separation barrel by the cleaning rod.
