Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides Figure 1-4The dust recovery device for polyester powder coating production shown in the figure comprises a recovery box 1 and an intake pipe 2 provided on one side of the surface of the recovery box 1. Dust isolation structures 5 are slidably connected on both sides of the inner wall of the recovery box 1 to filter the dust gathered in the recovery box 1. A pressure drop structure 6 is provided on the top of the dust isolation structure 5 inside the recovery box 1 to keep the pressure drop of the dust isolation structure 5 at a reasonable level by injecting compressed air. An ash storage structure 7 is provided at the bottom of the recovery box 1 to uniformly collect the air inside the recovery box 1. When the utility model is used, the air containing dust is inhaled through the intake pipe 2, and then the dusty air is forced into the recovery box by the air pressure. Inside the box 1, the air containing dust will be filtered through the multiple dust bags 502 on the top. The dust bags 502 effectively filter the dust in the air, and the clean air will be discharged through the exhaust pipe 3 on the top. When a large amount of dust gathers on the surface of the dust bag 502 and clogs it, the compressed air contained in the compressed air pipe 603 is sprayed out through the nozzle 605 to knock down the dust on the surface of the dust bag 502, and finally collected in the storage drawer 703, avoiding manual cleaning and improving the dust recovery efficiency. The automatic dust collection effect improves the use effect of the device and the cleanliness of the device when recovering dust.

[0022] like Figure 2-3 As shown, the dust isolation structure 5 includes a supporting platform 501 and a dust bag 502. The supporting platform 501 is arranged inside the recycling box 1, and multiple dust bags 502 are arranged inside the supporting platform 501. The dust isolation structure 5 also includes a sliding block 503. The two sliding blocks 503 are fixedly connected to both sides of the surface of the supporting platform 501, and one side of the surface of the two sliding blocks 503 is slidably connected to one side of the inner wall of the recycling box 1. The dust bag 502 can adsorb the dust contained in the air, thereby ensuring the integrity of the device.

[0023] like Figure 3 As shown, the pressure drop structure 6 includes a pressure drop box 601, a pressure drop cavity 602, and a compressed air pipe 603. The pressure drop box 601 is fixedly connected to one side of the surface of the recovery box 1, the pressure drop cavity 602 is opened inside the pressure drop box 601, and the compressed air pipe 603 is arranged inside the pressure drop cavity 602. The pressure drop structure 6 also includes a connecting pipe 604 and an injection head 605. The connecting pipe 604 is arranged on the opposite sides of the inner wall of the recovery box 1 and is located at the top of the dust isolation structure 5. Multiple injection heads 605 are all arranged on the bottom surface of the connecting pipe 604, and multiple injection heads 605 are all located at the top of the dust bag 502. The compressed air contained in the compressed air pipe 603 is used by the injection head 605 to knock down the dust adsorbed on the surface of the dust bag 502, so that the adsorption work of the dust bag 502 can continue.

[0024] like Figure 2As shown, the ash storage structure 7 includes an ash storage box 701 and an isolation net 702. The ash storage box 701 is arranged at the bottom of the recovery box 1, and the isolation net 702 is arranged on the opposite sides of the inner wall of the ash storage box 701.

[0026] Working principle of the utility model: When the utility model is used, the exhaust fan is first connected to the suction pipe 2. At this time, the air with dust will enter the interior of the recovery box 1 through the suction pipe 2. At this time, the air with dust will move upwards due to the pressure of the exhaust fan. While moving, the dust will be filtered through multiple dust bags 502. At this time, the dust in the air will be adsorbed by the surfaces of the multiple dust bags 502, and the filtered air will be discharged through the discharge pipe 3 at the top;

[0027] When the device works for a long time, a large amount of dust will be absorbed on the surface of the dust bag 502. In order to maintain the pressure drop of the dust bag 502, the compressed air contained in the compressed air pipe 603 is used to transport it to the interior of multiple spray heads 605 through the connecting pipe 604. Then, multiple dust bags 502 are sprayed at the same time through the spray heads 605 to knock down the dust absorbed on the surface of the dust bag 502, and finally drop it to the interior of the storage drawer 703 through the isolation net 702 for unified collection.
