[0041] When the liquid is located in the inner cavity of the filter plate 210 and is centrifugally rotating, the centrifugal force is used to make the liquid pass through the filter plate 210 for filtration. Compared with traditional filtration, this structure uses centrifugal force to pressurize the liquid filtration, thereby improving the efficiency of liquid filtration and avoiding the problem that traditional filtration equipment needs external pressure equipment to improve liquid filtration efficiency.

[0042] On the other hand, the centrifugal frame 209 is set in a cone shape, so that the foreign matter isolated by the filter plate 210 in the liquid can move to the side of the drain tank 208 under the guidance of the liquid and the filter plate 210, so that the foreign matter can be automatically discharged from the inner cavity of the filter plate 210.

[0043] In a preferred embodiment: the outer wall of the support shaft 205 close to the collecting bin 201 is fan-shaped and fixedly equipped with a plurality of support rods 212, the end of the support rod 212 away from the support shaft 205 is fixedly equipped with a flushing plate 213, the end of the support shaft 205 away from the sealing plate 204 is fixedly equipped with a treatment agent flushing box 214, the inner cavity of the support shaft 205 is provided with a treatment agent transmission groove 215, and the treatment agent transmission groove 215 is connected to the inner cavity of the treatment agent flushing box 214.

[0044] In the above structure, the cavity formed between the accommodating bin 103 and the cross 102 is connected to the treatment agent transmission groove 215, and the treatment agent transmission groove 215 is connected to the inner cavity of the treatment agent flushing box 214, so that the wastewater treatment agent stored in the cavity between the rotating groove 104 and the cross 102 can be moved to the inner cavity of the treatment agent flushing box 214. After the wastewater treatment agent in the inner cavity of the treatment agent flushing box 214 is melted by the liquid discharged from the driven shaft 4, the wastewater treatment agent stored in the cavity between the rotating groove 104 and the cross 102 can be automatically moved to the inner cavity of the treatment agent flushing box 214 to be replenished, thereby solving the problem that traditional equipment requires manual addition of wastewater treatment agents.

[0045] In a preferred embodiment: the cavity formed between the accommodating bin 103 and the cross 102 is connected to the treatment agent transmission groove 215, the side of the driven shaft 4 away from the water inlet pipe 5 and the outer wall of the centrifugal frame 209 close to the rotating shaft frame 3 are fixedly assembled, one group of discharge square tubes 202 and the sewage trough 208 correspond to each other, and the discharge square tubes 202 are rotatably sleeved with the outer edge of the centrifugal frame 209, another group of discharge square tubes 202 correspond to the position of the discharge port 207, and the discharge square tubes 202 and the discharge port 207 are fixedly assembled, and the through groove 211 corresponds to the position of the sewage trough 208.

[0051] Step 2: The centrifugal frame 209 is arranged in a conical shape, so that the foreign matter in the liquid separated by the filter plate 210 can move toward the drain groove 208 under the guidance of the liquid and the inner wall of the filter plate 210, so that the foreign matter can be automatically discharged from the inner cavity of the filter plate 210 through the drain groove 208;

[0052] Step 3: By setting the flushing plate 213, the liquid on the inner wall of the filter plate 210 rotated by the centrifugal force can be guided by the flushing plate 213 and discharged to the top port of the flushing plate 213, so that the liquid can flush the inner wall of the end of the filter plate 210, and the foreign matter adhered to the inner wall of the filter plate 210 can be peeled off, thereby increasing the service life of the filter plate 210;

[0053] Step 4: After the wastewater treatment agent in the inner cavity of the treatment agent flushing box 214 is melted by the liquid discharged from the driven shaft 4, the wastewater treatment agent stored in the cavity between the rotating trough 104 and the cross 102 can be automatically moved to the inner cavity of the treatment agent flushing box 214 through the treatment agent transmission trough 215 to be replenished, thereby solving the problem of manual addition of wastewater treatment agent required in traditional equipment.
