Description

Technical Field

[0001] The utility model relates to the technical field of dredging equipment, and more specifically to a flow-assisting and warehouse-clearing device. 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

The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the utility model provides a flow-assisting warehouse clearing device, including a first nozzle 1, a second nozzle 2, a gas injection assembly 3, a liquid injection assembly 4, a valve assembly 5 and a control assembly 6; the first nozzle 1 has a first nozzle 11 arranged horizontally, and a first pipe 12 connected to the first nozzle 11; the second nozzle 2 has a second nozzle 21 arranged obliquely downward, and a second pipe 22 connected to the second nozzle 21; the gas injection assembly 3 includes a gas compressor 31 and a third pipe 32 connected to the gas compressor 31; the liquid injection assembly 4 includes a water pump 41 and a third pipe 32 connected to the water pump The fourth pipeline 42 of 41; the valve component 5 is respectively connected to the first pipeline 12, the second pipeline 22, the third pipeline 32 and the fourth pipeline 42, the valve component 5 has a first state and a second state, when the valve component 5 is in the first state, the first pipeline 12 is only connected to the third pipeline 32, and the second pipeline 22 is only connected to the fourth pipeline 42; when the valve component 5 is in the second state, the first pipeline 12 is only connected to the fourth pipeline 42, and the second pipeline 22 is only connected to the third pipeline 32; the control component 6 is electrically connected to the valve component 5, and is used to control the valve component 5 to switch between the first state and the second state.
