Claims

1. A dust recovery device, characterized by: It includes a first chamber and a second chamber that are spaced apart from left to right and are interconnected; The first chamber is equipped with a cyclone separator and a dust collection box, and the material discharge port at the bottom of the cyclone separator is connected to the dust collection box; the first chamber has an air inlet, and the air inlet of the cyclone separator is connected to the air inlet; The second chamber is provided with a first partition, which divides the second chamber into an upper chamber and a lower dust collection chamber. The upper chamber is provided with a second partition, which divides the upper chamber into a ventilation chamber and a dust removal chamber arranged side by side; one end of the ventilation chamber is connected to the air outlet at the top of the cyclone separator; The dust removal chamber is provided with a third partition, which divides the dust removal chamber into a cleaning chamber and a filtration chamber arranged vertically. The other end of the ventilation chamber is connected to the filtration chamber. The third partition has several filter mounting holes, and several filters are installed with each filter mounting hole facing downwards. The air outlet of each filter is connected to the cleaning chamber. The lower dust collection chamber is connected to the filtration chamber, and the inlet of the lower dust collection chamber is directly below all the filters. The cleaning chamber has an exhaust port that connects to the outside. A pulse air pipe is installed in the cleaning chamber. The pulse air pipe is equipped with a solenoid valve and several backflush high-pressure air nozzles corresponding to the filters. Each backflush high-pressure air nozzle is opposite to the air outlet of a corresponding filter. An air tank and an electrical control box are installed on the right outer wall of the second chamber. The right end of the pulse air pipe extends out of the second chamber and communicates with the air tank. The electrical control box is equipped with a PLC controller and a fingerprint reader. The PLC controller is connected to the fingerprint reader and the solenoid valve respectively so that the solenoid valve can be controlled to work only after the fingerprint is correctly recognized.

2. The dust recovery device according to claim 1, characterized in that: The dust collection box is located directly below the cyclone separator.

3. The dust recovery device according to claim 1, characterized in that: The air outlet at the top of the cyclone separator is connected to one end of the ventilation chamber via a guide bend.

4. The dust recovery device of claim 1, wherein: The inner wall of the filter chamber is equipped with a first pressure sensor for detecting the air pressure in the filter chamber, and the first pressure sensor is connected to the PLC controller.

5. The dust recovery device of claim 4, wherein: A second pressure sensor for detecting the air pressure in the cleaning chamber is installed on the inner wall of the cleaning chamber. The second pressure sensor is connected to a PLC controller to control the operation of the solenoid valve based on the pressure difference between the first pressure sensor and the second pressure sensor.

6. The dust recovery device of claim 1, wherein: The filter is a cartridge filter.

7. The dust recovery device of claim 6, wherein: The cartridge filter includes a first filter cartridge, a second filter cartridge, and a magnetic mesh frame; The second filter cartridge is installed inside the first filter cartridge, and the magnetic mesh frame is installed inside the second filter cartridge.

8. The dust recovery device according to claim 7, characterized in that: The first filter cartridge is a first nanofiber filter cartridge, and the second filter cartridge is a second nanofiber filter cartridge.

9. The dust recovery device of claim 8, wherein: The pore size of the first nanofiber filter cartridge is larger than that of the second nanofiber filter cartridge.
