The other end of the solenoid valve 6 is connected to the first powder chamber 1 and the second powder chamber 2.

[0020] During implementation, the primary recovery unit is a filter cartridge system used for the initial separation of large and heavier particles from the powder.

[0021] Furthermore, such as Figure 2 as well as Figure 3 As shown, a secondary recovery device 3 is provided between the first powder chamber 1 and the second powder chamber 2. The secondary recovery device 3 is used for secondary recovery of the powder generated by the first powder chamber 1 and the second powder chamber 2. The secondary recovery device 3 includes a cyclone recovery device 31 and a secondary air duct 32.

The output end of the cyclone recovery device 31 is equipped with the secondary air duct 32, and the secondary air duct 32 is connected to the connecting pipe sleeve 42.

[0022] During implementation, the secondary recovery device 3 is a cyclone system with a filter element for fine filtration, which is used to further filter and remove the remaining fine powder to achieve a higher recovery accuracy.

[0023] Furthermore, such as Figure 3 as well as Figure 4 As shown, a regulating valve assembly 4 is provided at the connection between the secondary recycling device 3 and the first powder chamber 1 and the second powder chamber 2. The regulating valve assembly 4 is used to control the on / off operation of the connection between the secondary recycling device 3 and the first powder chamber 1 and the second powder chamber 2.

[0025] Working principle: When powder is generated in the two powder chambers, the air containing the powder is introduced into the primary recovery device through the primary air duct 5.

[0026] In the primary recycling unit, the filter cartridge system is used to separate large and heavier particles of powder. These separated powders are then collected centrally through specific pipes or collection devices.

[0027] After primary air recovery, the air enters secondary air recovery unit 3 under the action of regulating valve assembly 4. Under the action of cyclone system and filter cartridge fine filtration equipment, fine powder is further removed, so that the discharged air meets environmental protection standards.

[0028] By controlling the regulating valve assembly 4, the connection between different powder chambers and the recycling system can be flexibly switched, enabling the two powder chambers to be recycled alternately or simultaneously, thereby improving the system's efficiency.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
