The end of the auxiliary shaft 5 penetrates through the shaft hole and is provided with a T-shaped ring groove for the T-shaped ring to slide in. In addition, the shape of the push block 13 is the same as that of the second filter groove 12, which is a trapezoidal shape with the end face size gradually decreasing towards the inside of the water inlet pipe. A return spring 10 is also fixedly installed on the right end face of the partition plate, and the right end of the return spring 10 abuts against the left end of the auxiliary shaft 5.

[0041] As shown in Figure 4 , four water inlet grooves are also formed in the auxiliary shaft 5 in the water inlet pipe. At the same time, a plurality of water outlet holes 15 are also circumferentially formed in the auxiliary shaft 5 and penetrate through the brush roller two 6. A through groove 16 is coaxially formed in the auxiliary shaft 5 and communicates with the water inlet grooves and supplies water to the water outlet holes 15. A plurality of fan blades 17 are also coaxially fixedly installed on the auxiliary shaft 5 to guide the water flow into the water inlet grooves. In addition, the actuating mechanism, the fan blades 17, and the water inlet grooves are sequentially arranged on the auxiliary shaft 5 in the direction of the water flow into the through groove 16.

[0042] In this embodiment, a residue discharge groove is also formed in the top of the water inlet pipe on the left side of the partition plate. The residue discharge groove communicates with all the second filter grooves 12. The length of the push block 13 is greater than the thickness of the push plate. The small impurities filtered out of the second filter grooves 12 can be pushed into the residue discharge groove by the push block 13 for collection.

[0043] Further, the water inlet pipe is also provided with an arc-shaped sealing plate 14 capable of sealing the residue discharge groove, the outer wall of the arc-shaped sealing plate 14 is completely attached to the inner wall of the water inlet pipe, and the two ends of the arc-shaped sealing plate 14 are formed with limiting blocks, the inner side of the water inlet pipe and the wall surface of the partition plate are provided with limiting grooves for allowing the limiting blocks to slide therein, so as to prevent the arc-shaped sealing plate 14 from being separated. The water inlet pipe is also provided with an ejection mechanism for ejecting the arc-shaped plate out of the residue discharge groove, the ejection mechanism comprises an arc-shaped ejection rod fixedly connected between the arc-shaped sealing plate 14 and the end surface of the water inlet pipe, an ejection table integrally formed in the water inlet pipe and an ejection spring fixedly installed between the ejection table and the arc-shaped ejection rod. As shown in the cross-sectional view of FIG. Figure 4 The arc-shaped ejection rod, the ejection table and the ejection spring are not shown in the figure because the arc-shaped ejection rod is fixed to the front end surface of the arc-shaped sealing plate 14.

[0044] The partition plate is also coaxially provided with a through hole, and the control mechanism for pulling the arc-shaped sealing plate 14 to seal the residue discharge groove when the auxiliary shaft 5 is reset is installed at the end of the auxiliary shaft 5 and passes through the through hole, the control mechanism comprises a telescopic sleeve and a pulling rope 18 passing through the through hole. The end of the telescopic sleeve is outwardly protruded to form a limiting ring table, the left end of the rotating shaft is provided with a limiting ring groove for allowing the end of the telescopic sleeve with the limiting ring table to extend into, and the other end of the telescopic sleeve is fixed to the partition plate.

[0045] In use, water is first poured into the filter cartridge 1, the communication box 3 and the water inlet box 2, and then the driving motor is started to drive the main shaft 4 to rotate;

[0046] The rotation of the main shaft 4 drives all the auxiliary shafts 5 to rotate synchronously through the reverse transmission mechanism, and the rotation direction of the auxiliary shafts 5 is opposite to that of the main shaft 4. During the rotation of the main shaft 4, the ejection plate 8 can also intermittently eject into the rotating shaft through the sleeve 9 and the filter cartridge 1.

[0047] The rotation of the auxiliary shaft 5 drives the fan blades 17 to rotate synchronously to guide the water flow into the water inlet groove, the through groove 16 and the water outlet hole 15, and finally sprayed out through the water outlet hole 15 to realize the circulation of the water body. The transverse sliding of the auxiliary shaft 5 drives the push plate and the push block 13 to move synchronously. When the push block 13 moves to the left, the telescopic sleeve is contracted, the pulling rope 18 enters the water inlet pipe on the left side of the partition plate, the arc-shaped sealing plate 14 is ejected out of the residue discharge groove by the ejection spring, and the residue discharge groove is opened. When the push plate moves to the right, the arc-shaped sealing plate 14 seals the residue discharge groove.

[0048] Then, shrimps are put in, specifically live shrimps.

[0049] The shrimps enter the filter cartridge 1 through the feeding port, and are cleaned by the staggered brush rollers one and two 6 on the main shaft 4 and the auxiliary shaft 5, and are stirred and moved in the filter cartridge 1 by the brushes of the brush rollers one and two 6.

[0050] And such as Figure 5 As shown, the secondary shaft 5 and the main shaft 4 can not only rotate relative to each other, but also slide laterally in an alternating manner. This allows for brushing of the shrimp shells not only perpendicular to the direction of rotation, but also parallel to the direction of rotation, resulting in a more thorough cleaning. Simultaneously, the water jet from the outlet 15 can also rinse the shrimp shells.

[0051] Meanwhile, the debris washed off will enter the connecting box 3 through the first filter tank, and the sewage will also flow into the connecting box 3, where it will be treated by the aeration pipe 7 through the aeration method.

[0052] When the secondary shaft 5 drives the fan blades 17 to rotate synchronously, the filtered water will enter the inlet tank through the first filter tank. The first filter tank filters out small impurities, which are then pushed into the open slag discharge tank by the left-moving paddle 13. Finally, they are collected in the inlet pipe and isolated by the arc-shaped sealing plate 14. Meanwhile, large impurities are stored at the bottom of the connecting box 3, specifically at the bottom of the connecting box 3 below the first filter tank.

[0053] After the shrimp have been cleaned, an external basket can be placed at the feed inlet, and the basket opening can be inserted into the filter cylinder 1 to collect the shrimp during the mixing process.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
