[0002] Feed is needed in the abalone farming process, and the feed needs to be filtered before use during processing.

[0003] After searching, the patent with application number 2023200863439 discloses a filtering device suitable for abalone feed, including a body, a discharge trough is provided at the bottom of the body, and a crushing paddle is welded on the side of the rotating rod to crush the abalone feed preliminarily filtered by the coarse filter and filter it again through the fine filter, thereby improving the quality of the abalone feed.

[0004] The above device has the following defects when used:

[0005] Although the device improves the filtration efficiency through double filtration and disintegration treatment, it is unable to process the filtration residues, resulting in the accumulation of residual feed, which affects the subsequent continuous filtration effect;

[0006] When the device conveys the filtered feed through the screw rod, on the one hand, the dry feed is easily crushed, and on the other hand, the incompletely dried feed is easily squeezed and agglomerated, thereby affecting the properties of the filtered feed. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-6 The present invention provides a technical solution: a filtering method suitable for abalone feed, comprising the following steps:

[0037] S1, add the feed to be processed into the solid box 1 through the top, and make the feed enter the uppermost circular groove 2, then drive the motor 13 to work, drive the bullet head 8 to rotate through the rotating shaft 6, so as to select and crush the feed, so that the feed moves and passes through the connecting groove 3 to the lower circular groove 2, so as to obtain the feed of the required specifications through step-by-step processing and screening, and then the processed feed passes through the lower connecting groove 3 to enter the filter box 51 for filtering, and if the feed is stuck in the connecting groove 3 during the feed screening process, the rotating shaft 6 drives the bullet head 8 to align with the connecting groove 3 vertically downward, and then the air pump 12 works to increase the air pressure inside the air cavity 7, and pushes the pin rod 9 to move through the high-pressure air, so that the pin rod 9 drives the bullet head 8 to enter the connecting groove 3, and compresses the spring 11, so as to pound the stuck feed to make it unloaded; after the cleaning is completed, the air pump 12 stops working, and the spring 11 rebounds, so that the bullet head 8 is reset;

[0038] S2. After the feed enters one side of the inner part of the filter box 51, it is filtered through one side of the filter plate 52. At the same time, the reciprocating motor 536 works to drive the two transmission gears 535 to rotate, so that the rotating rod 534 drives the rotating plate 531 through the arc bar 533 to reciprocate under the other filtering area, and the contact between the rotating plate 531 and the filter plate 52 causes the filter plate 52 and the feed to vibrate, so as to filter the feed and prevent the feed from clogging the filter holes. The filtered feed is discharged from the bottom of the filter box 51, and the feed that does not meet the size remains on the surface of the filter plate 52. When a lot of feed is accumulated on one side of the filter plate 52, the displacement motor 510 works to drive the driving gear 59 to rotate, so that the limit bar 58 drives the baffle 56 to move, thereby blocking the upper part of the accumulated feed and allowing the feed to be filtered through the other side of the filter plate 52, and then repeat the above steps to perform a continuous filtering process;

[0039] S3. When the top of the accumulated feed is blocked, the electric control valve on one end of the corresponding suction pipe 544 is opened, and then the heating fan 548 absorbs the accumulated feed through one end of the suction pipe 544 and the connecting pipe 543, the solid sleeve 541 and the filter cartridge 545, and blows air into the interior of the solid box 1, and heats the air to dry the feed, and facilitate the feeding and discharging of the feed. At the same time, as a preferred method, the interior of the solid box 1 and the filter box 51 can be pre-dried before processing, and the adsorbed refluxed feed is filtered through the filter cartridge 545 and retained therein. When the accumulated amount reaches a certain level, the weight of the feed is greater than the elastic force of the torsion spring, and then the two arc pieces 546 are pressed down to open them, and then the feed in the filter cartridge 545 will fall into the hopper 547, and then flow back to the interior of the solid box 1 for re-screening and crushing;

[0040] S4. When the feed is refluxed, the rotating plate 531 drives the rubber pad 5324 to fit with the filter plate 52, and then opens the electromagnetic valve 5323 on the corresponding fixed pipe 5322. Then the output end of the telescopic rod 5326 extends to drive the push plate 5325 to move inside the inner cavity 5321 to change its internal pressure, and blows air to the rubber pad 5324 through the fixed pipe 5322, so that the rubber pad 5324 expands and deforms, and the deformed part of the rubber pad 5324 enters the filter hole of the filter plate 52, so as to clean the inside of the filter hole and make all the accumulated feed reflux, thereby improving the filtering effect of the feed.
