[0025] The working principle of this utility model is as follows:

[0026] In use, raw materials are fed into storage bin 1-1 through inlet 1-2. Then, the operating door 2-3 is opened, and the baffle 1-4-4 is pulled down and slid along guide post 1-4-3. When the baffle 1-4-4 reaches the bottom of guide post 1-4-3, the set screw is tightened to secure it. At this point, the baffle 1-4-4 no longer obstructs the filter screen 1-4-2. The raw materials in storage bin 1-1 are filtered through filter screen 1-4-2 and flow out into collection bin 2-1 for collection. Alternatively, they can be collected through outlet 2-2. This device is connected to an external power source; powering motor 1-3 drives rotating shaft 3- 1. Rotation: The rotation of the rotating shaft 3-1 drives the rotating plates 3-3 via the support column 3-2. The rotation of the rotating plates 3-3 agitates the raw materials. Simultaneously, the lower ends of multiple rotating plates 3-3 successively shorten, ensuring thorough agitation of the raw materials in the storage container 1-1 and preventing the raw materials at the lower end of the storage container 1-1 from remaining stagnant. The rotation of the rotating shaft 3-1 also drives the spiral blades 3-4 to rotate. The rotation of the spiral blades 3-4 moves the raw materials downwards, increasing the filtration speed. Simultaneously, the centrifugal force generated by the spiral blades 3-4 as they move the raw materials throws them onto the filter screen 1-4-2, thus improving the filtration efficiency of the filter screen. 1-4-2 The faster filtration through the filter screen 1-4-2 further increases the filtration speed. The rotating shaft 3-1 drives multiple brushes 3-5 to rotate. The rotating brushes 3-5 brush off the material adhering to the filter screen 1-4-2, and the spiral blades 3-4 carry the impurities to the bottom of the filter bucket 1-4-1 for collection. When all the raw materials in the storage bucket 1-1 have been filtered, and cleaning is required, open the operating door 2-3, push the baffle 1-4-4 upwards to reset it and secure it with the set screw, then open the valve to pour clean water into the storage bucket 1-1, power on the motor 1-3, and rotate the lever 3-3 to agitate the water. The inside of the storage tank 1-1 can be cleaned. Due to the obstruction of the baffle 1-4-4, the water no longer flows out through the filter screen 1-4-2, but flows out through the waste outlet 1-4-5 and the waste pipe. As the water flows out, it passes through the spiral blades 3-4 and the brush 3-5, which can further wash the filter screen 1-4-2. At the same time, the spiral blades 3-4 drive the water downward and generate centrifugal force, which can clean the filter screen 1-4-2 more thoroughly and make the water flow out quickly through the waste outlet 1-4-5, increasing the cleaning speed. After cleaning, the above steps are reversed to perform the next filtration.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
