[0032] Water is injected into the water tank 13 through the water inlet pipe 14 for storage, the water pump 15 is started to make the water pumping pipe 17 suck the water, so that the water enters the annular pipe 24 in the freeze-thaw tank 7 through the water delivery pipe 16 and is sprayed through the nozzle 25 to spray and clean the inside of the freeze-thaw tank 7, and the suction pump 9 is started to make the water in the freeze-thaw tank 7 enter the annular pipe 24 in the screening tank 6 through the first suction pipe 10 and the first delivery pipe 18, and is sprayed out through the nozzle 25. After this step, the suction pump 2 11 is started to make the water enter the storage tank 3, and the sewage is discharged through the drain pipe 5, and the inside of the device is cleaned by multiple cycles; the telescopic part 26 is compressed when the screening plate 23 moves up, and when the screening plate 23 moves down, the limit block 27 moves downward due to the rebound force of the telescopic part 26, and drives the screening plate 23 to move downward, thereby limiting the screening plate 23.

[0033] Reference Figure 2-Figure 4 The outer rear sides of the freeze-thaw tank 7 and the screening tank 6 are fixedly connected with a motor 20, the output end of the motor 20 is fixedly connected with a rotating shaft 21, the front and rear sides of the rotating shaft 21 are fixedly connected with an eccentric wheel 22, a screening plate 23 is arranged on the upper part of the eccentric wheel 22, and a limiting block 27 is arranged on the upper part of the screening plate 23.

When the screening plate 23 rises, the limit block 27 compresses the telescopic member 26 when it moves upward. When the eccentric wheel 22 continues to rotate, the limit block 27 moves downward under the elastic force of the telescopic member 26, and drives the screening plate 23 downward, and limits it through the limit groove 28 to avoid tilting. The suction pump 9 is started to drive the first suction pipe 10 to suck the freeze-thaw liquid preliminarily screened, so that it enters the annular pipe 24 set in the screening tank 6 through the first conveying pipe 18, and the freeze-thaw liquid is sprayed into the interior of the screening tank 6 through the nozzle 25 for secondary screening, thereby realizing physical screening of the animal tissue, and due to the different densities of the screening plate 23, the molecular weight of the freeze-thaw collection liquid is adjusted;
