[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the process of producing aquaculture puffed feed, the present invention uses slots and blocks to quickly install and disassemble filter bags, thereby reducing the difficulty of installation operation, and the plug-in tube and the sleeve can fit tightly to ensure sealing, and when a pulse transmitter and an air storage bag are used, the air storage bag is used to spray reverse airflow to recoil the filter bag when there is a lot of dust attached to the surface of the filter bag, so that the dust on the surface of the filter bag can be quickly removed, the filtering effect of the filter bag is ensured, and the filtering efficiency is improved.

[0021] The filter bag of the present invention is used for filtering dusty gas by using the filter bag. When the filter bag is installed, the card block moves along the slot to the card slot position and moves toward the bottom of the card slot. The card block acts on the pressure plate to move downward, and the pressure plate drives the movable ring, the connecting rod and the movable frame to move downward together.

[0022] 3. In the process of using the filter bag to filter the dust-laden gas, the present invention will drive the connecting rod to move downward during the process of installing the filter bag, and the movement of the connecting rod will drive the fixed block to move together, and the fixed block will move to the surface position of the extension frame. Subsequently, when the filter bag filters the dust-laden gas, the dust-laden gas after passing through the filter bag will flow out through the insert tube and the sleeve, and the airflow will drive the fan blades to rotate, and the driving of the fan blades to rotate will drive the rotating shaft and the extension frame to rotate together, and the extension frame will drive the pushing block to rotate together, and the pushing block will intermittently act on the fixed block, and the fixed block, the connecting rod, the movable ring and the pressure plate will move upward together, and the pressure plate will act on the filter bag to shake upward through the block, the fixed tube and the fixed ring, which is beneficial to continuously shaking the filter bag during the process of filtering the dust-laden gas, reducing the adhesion of dust on the surface of the filter bag, ensuring the filtration of the filter bag, and improving the filtration efficiency.

After passing through the filter bag 19, the dust will become purified air after being filtered by the filter bag 19. The dust will adhere to the surface of the filter bag 19. When there is a lot of dust on the surface of the filter bag 19 and it needs to be cleaned, the pulse transmitter 7 will emit an electromagnetic pulse to trigger the air storage bag 21 to discharge the gas. The airflow will be discharged through the blowing pipe 22 and the blowing port 23. The filter bag 19 will swell under the action of the airflow, and the dust on the surface of the filter bag 19 will be Shaking off is beneficial for using the air storage bag 21 to spray reverse airflow to recoil the filter bag 19 when there is a lot of dust attached to the surface of the filter bag 19, which can quickly remove the dust on the surface of the filter bag 19, ensure the filtering effect of the filter bag 19, and improve the filtering efficiency. The dust cleaned and fallen on the surface of the filter bag 19 will fall into the conical hopper, and the dust will gradually move along the inner wall surface of the conical barrel 24 to the bottom of the conical barrel 24, and then the air shut-off device 26 is started to discharge the dust inside the conical barrel 24, thereby ensuring the subsequent filtering effect of the dust-containing gas.

[0042] In the process of filtering the dusty gas by using the filter bag 19, when the filter bag 19 is not completely installed on the surface of the mounting plate 8, dusty gas will pass through the through-port 9, and the filter bag 19 cannot filter. As a further solution of the present invention, a cross-shaped moving frame 27 is slidably connected to the inner wall surface of the sleeve 11 up and down, and a plurality of retractable fan-shaped baffles 28 are fixedly connected to the surface of the moving frame 27. A plurality of spiral guide grooves 29 are provided on the inner wall surface of the sleeve 11. The retractable side of the fan-shaped baffle 28 slides in the guide groove 29. The surface of the moving frame 27 is fixedly connected to the plurality of spiral guide grooves 29.

[0043] In the process of using the filter bag 19 to filter the dust-containing gas, when the filter bag 19 is installed, after the block 18 moves along the slot 13 to the position of the slot 14, it will move to the bottom of the slot 14, and the block 18 will act on the pressure plate 32 to move downward, and the pressure plate 32 will drive the moving ring 31, the connecting rod 30 and the moving frame 27 to move downward, and the fan-shaped baffle 28 will move downward together, and the telescopic end of the fan-shaped baffle 28 will move along the guide groove 29, and the fan-shaped baffle 28 will shrink under the action of the guide groove 29, and the through-port 9 will be connected with the sleeve 11, and the through-port 9 without the filter bag 19 installed will be blocked The plate and the movable frame 27 are blocked, and dust-containing gas cannot pass through. This is beneficial for blocking the through-holes 9 where no filter bags 19 are installed when the filtering effect can be satisfied without installing filter bags 19 on all the mounting plates 8, thereby ensuring the filtering effect of the filter bags 19 and avoiding the passage of dust-containing gas through the through-holes 9 where no filter bags 19 are installed, which cannot achieve the filtering effect.

Then, when the filter bag 19 filters the dust-laden gas, the dust-laden gas after passing through the filter bag 19 will flow out through the insert tube 15 and the sleeve 11, and the airflow will act to drive the fan blade 35 to rotate, and the driving fan blade 35 to rotate will drive the rotating shaft 34 and the extension frame 36. The extending frame 36 will drive the pushing block 37 to rotate together, and the pushing block 37 will intermittently act on the fixed block 38. The fixed block 38, the connecting rod 30, the movable ring 31 and the pressure plate 32 will move upward together, and the pressure plate 32 will act on the filter bag 19 to shake upward through the clamping block 18, the fixed cylinder 17 and the fixed ring 16. This is beneficial for continuously shaking the filter bag 19 during the filtering process of the dust-containing gas, reducing the adhesion of dust on the surface of the filter bag 19, ensuring the filtration of the filter bag 19, and improving the filtration efficiency.

[0047] During the installation of the filter bag 19 , the insert 15 will move into the interior of the sleeve 11 , and the bottom of the sleeve 11 will contact the sealing cylinder 39 . Then the sleeve 11 will squeeze the sealing cylinder 39 , and the bottom of the sleeve 11 can fit tightly with the sealing cylinder 39 , thereby ensuring the sealing effect between the sleeve 11 and the insert 15 .

[0048] During the installation of the filter bag 19, the insert 15 cannot be accurately moved into the sleeve 11. As a further solution of the present invention, the bottom of the sleeve 11 is a tapered opening inclined outward;
