[0025] The negative pressure exhaust device 3, the feeding hopper 1 and the double valve recovery device 4 are arranged beside the storage bin (2) to reduce the occupied space in height, thereby adapting to the high floors on the ground floor.

[0028] The deposition chamber A40 and the deposition chamber B41 are arranged in an upper and lower distribution, and the discharge end of the deposition chamber A40 is connected to the feed end of the deposition chamber B41.
[0029] Specifically, when a certain amount of product is collected in the deposition chamber A40, gravity is used to allow the product in the deposition chamber A40 to enter the deposition chamber B41, where it is further collected and finally returned to the feed pipe 10 from the deposition chamber B41.
[0030] The discharge end of the deposition chamber A 40 is provided with a discharge pipe A 400 connected to the deposition chamber B 41 , and the discharge end of the deposition chamber B 41 is provided with a discharge pipe B 410 connected to the feed pipe 10 .

[0033] The discharge valve A401 and the discharge valve B411 adopt an interlocking design. The two are a pair of interlocking valves. The open state of the discharge valve A401 requires the discharge valve B411 to remain in the closed state, and the discharge valve B411 can only be opened when the discharge valve A401 is closed.

A production processing link is also provided upstream of the low-layer high negative pressure discharge packaging system, and a packaging and transportation link is also provided downstream. Specific implementation method:
[0045] When the upstream product processing is completed, the worker operates the machine to put the product into the feeding hopper 1, and the screening device in the feeding hopper 1 screens the product into large and small powders;
[0046] After the powder is screened, small particles enter the feed pipe 10 downward, while large particles are screened out from the pipe opening on the side of the feed hopper 1 for further processing;
[0047] During the above work, the negative pressure exhaust device 3 is working at the same time, and the exhaust gas route is the feeding hopper 1, the material conveying pipe 10, the storage bin 2, the negative pressure exhaust pipe B 301, the deposition chamber A40, the negative pressure exhaust pipe A300, and finally to the negative pressure exhaust device 3.
[0048] When the small particles enter the storage bin 2, they are deposited and stored in the storage bin 2 by gravity;
[0049] During the storage process, a large amount of floating small particles are generated, and the negative pressure exhaust pipe B 301 is used to suck the large amount of floating small particles into the deposition chamber A40;
[0050] Sedimentation chamber A40 performs secondary deposition of floating small particles;

After completion, the discharge valve A401 is closed, and the discharge valve B 411 is opened, and the collected product re-enters the feed pipe 10;
[0052] Finally, a cycle of product collection is completed.
[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
