Technical Field

[0001] The utility model relates to the field of garbage classification, in particular to a pneumatic separation device for garbage classification. Background Technique

[0002] Garbage classification generally refers to the general term of a series of activities that classify, collect, transport and process garbage according to certain regulations or standards, so as to transform it into public resources.

[0003] After retrieving the patent document with the publication number of CN215542734U, this patent document discloses "a pneumatic separation device for domestic garbage classification. This device disperses the just unpacked and aggregated garbage by setting several guide plates on both sides of the feeding pipe, and conveys the hot air inside the heating box to the inside of the feeding pipe through a blower to dry the wet garbage inside, which is convenient for the high-pressure blower to perform pneumatic separation on the garbage, and solves the problem that the high-pressure blower could not effectively perform pneumatic separation on the aggregated and wet garbage before".

[0004] Although the above device processes some garbage clusters that adhere together due to moisture through the cooperation of several guide plates and a drying structure, so as to separate them to avoid affecting pneumatic separation. When the garbage cluster that adheres together due to moisture is large, it is difficult to shake the adhered garbage cluster apart, so it is difficult to dry the inside of the garbage cluster during drying.

When the drive motor 37 is started, the three spreading frames 38 can be rotated, so that the spreading frames 38 can break up the fallen garbage clusters. By starting the hot air blower 39, a high temperature can be generated inside the working frame 35, so as to dry the wet garbage.
