Description

Technical Field

[0001] The utility model relates to the technical field of dredging equipment, and more specifically to a pneumatic flow-assisted warehouse clearing system. Background Art

[0002] Silos are used in various industries such as mining, metallurgy, chemical industry, building materials, machinery, etc. to transport materials. Due to internal friction, deliquescence, electrification, component segregation and other reasons of the materials in the silo, "blocking" and "arching" are caused, resulting in a reduction in silo capacity and even silo blockage, which in turn causes feeder failures such as material cutoff, affecting production and even causing safety accidents. In order to prevent silo blockage, the inner wall of the silo needs to be cleaned from time to time.

[0003] Manual, air cannon and hydraulic loosening machine. Manual cleaning not only has a long cleaning cycle, poor cleaning effect and certain personnel safety hazards; air cannons must have a certain gap in the bin to be effective, and can only clean local areas. When in use, there is a lot of noise, and when there is no gap, the compressed air of the air cannon cannot penetrate into the material; the hydraulic push rod that needs to be installed inside the bin of the hydraulic loosening machine becomes a support point for blocking and sticking materials. When the material is stored in the bin, the hydraulic push rod will move back and forth inside the material, and its force is not on most of the material. The hydraulic movement frequency is limited, generally only once a minute to block the material, which is inefficient and has a poor effect on cleaning arches. Utility Model Content
