[0029] The upper end of the cooling discharge tank 14 is connected to the B conical separation tank 7, and is controlled by a B tank discharge pneumatic butterfly valve 12. The lower end is connected to the B conical receiving tank 21, and is connected to the feeding cooling pipeline 19 through a pipeline, and is controlled by the feeding valve 20.

[0030] The following are the functions of each component:

[0031] Feed port 1: used to introduce powder into the device;

[0032] Stainless steel pipe 2: ensure smooth transmission of powder;

[0033] A cone separation tank 3: preliminary separation of powder and gas;

[0034] Exhaust pipe 4: discharges excess gas in the device;

[0035] Connecting pipe 5: connects conical separation tank A and conical separation tank B; a number of separation tanks can be added based on the separation efficiency.

[0036] A tank discharge pneumatic butterfly valve 6: controls the discharge of A conical separation tank;

[0037] B cone separation tank 7: further separation of powder;

[0038] Precision filter rod 8: finely filter the gas;

[0039] Filter rod mounting flange 9: fix the filter rod;

[0040] Stainless steel exhaust pipe 10 and exhaust valve 11: ensure smooth exhaust of gas;

[0041] B tank discharge pneumatic butterfly valve 12: controls the discharge of B conical separation tank;

[0043] Cooling purge fan 15 and fan air inlet 16: provide wind power for the cooling system;

[0044] Sterile filter 17: ensures the exhaust gas is sterile;

[0050] The usage method is: the gas containing powder particles enters the A conical separation tank 3 through the feed port 1 at one end of the stainless steel pipe 2. The powder particles in the gas are in the cyclone separator, and the airflow rotates at high speed with the dust. Due to the different weights of the dust particles, the centrifugal forces they are subjected to are also different. The heavy particles are thrown onto the wall of the separator and slide along the wall to be collected in the cooling discharge purge tank 13 connected to the A tank discharge pneumatic butterfly valve 6, and the light particles continue to rise with the rotation of the airflow through the exhaust pipe 4 connecting pipe 5 to enter the B conical separation tank 7 for further separation of the powder. The airflow rotates at high speed with the dust, and the heavy particles are thrown onto the wall of the separator and slide along the wall to be collected in the B tank discharge pneumatic butterfly valve 6. The light particles collected in the cooling discharge purge tank 14 connected to the butterfly valve 12 continue to rise with the rotation of the airflow and are blocked by the precision filter rod 8 and adsorbed on the surface of the precision filter rod 8. The excess gas is discharged from the stainless steel exhaust pipe 10 and the exhaust valve 18 on the top. At this time, the negative pressure fan 27 provides a negative pressure environment for the device through the three-way interface 28 and the exhaust valve 18. The precision filter rod 8 is installed on the filter rod mounting flange 9. The separation tank filter rod pulse cleaning valve 31 uses compressed air to pulse backblow the separation tank filter rod to make the powder fall off for effective collection. After the powder is collected in the cooling discharge purge tanks 13 and 14, it is transported to the conical receiving tank 21 through the cooling purge fan 15.

[0051] The utility model realizes multiple separation and filtration after the dust-containing air is sucked in, so as to recover the dust to the greatest extent, and finally achieves the effect of high recovery rate of dust recovery and sustainable production. A purge tank is set to continuously promote the recovery and prevent the accumulation of dust in the pipeline.
