Description

Technical Field

[0001] The utility model belongs to the technical field of biomaterial production and specifically relates to a silo purge device. Background Art

[0002] In the industrial field, silos are widely used as storage containers. When the density and particle size of the material are too small or there is a certain viscosity, it is easy to produce wall and crusting when stored in the silo for too long, and the material is easy to deteriorate due to moisture absorption. When the industry has high requirements for product quality, it has to face the problem of timely warehouse clearance. Traditional warehouse clearance mainly uses manual entry into the silo to remove the crusted and wall-hanging materials, but manual cleaning belongs to confined space operations, and the wall-hanging materials in the silo are prone to collapse, which is highly dangerous. In addition, there is mechanical cleaning using devices such as vibrators, stirrers, and conveyor belts, which can loosen, break, and flow the materials in the silo, thereby achieving the purpose of cleaning the silo, but mechanical cleaning requires regular maintenance and maintenance to ensure the normal operation of the machine device. Therefore, gas blowing is generally used to clean the silo, that is, gas is introduced into the silo, and the pressure and flow rate of the gas are used to blow out the materials in the silo, which has the advantages of simple operation, convenience and speed.

[0003] CN211726857U discloses a silo cleaning device and a cleaning apparatus thereof, which include a cleaning component and a purge component that are independent of each other, and both the cleaning component and the purge component can move up and down, thereby achieving comprehensive cleaning and purge everywhere, having a good cleaning effect, and being able to replace manual cleaning, thereby solving the technical problems of high work intensity and low cleaning efficiency caused by manual cleaning of silos in the prior art.

[0004] CN218786239U discloses a silo dust removal device, comprising a silo body and a telescopic assembly arranged in the silo body, the telescopic assembly comprising a telescopic tube, the telescopic tube is passed through the interior of the silo body, a telescopic cylinder is arranged on the outside of the telescopic tube, and the telescopic cylinder is extended and retracted to drive the telescopic tube to extend and retract; at least two groups of main pipes are circumferentially arranged at one end of the telescopic tube leading to the interior of the silo body, and at least two branch pipes are extended circumferentially from the main pipe; an air compressor is connected to one end of the telescopic tube leading to the outside of the silo body; through the extension and contraction of the telescopic tube, the silo body can be purged from top to bottom, the dust on the inner wall of the silo body can be purged, and the dust can be prevented from accumulating on the inner wall of the silo body to form lumps.

[0005] However, the current devices used for silo blowing can only blow up and down. This blowing method has limited effect on silos with severe wall hanging and crusting, and is prone to jamming. In addition, the up and down blowing method can only blow the side walls of the silo, which is more suitable for cleaning silos that are symmetrical up and down, such as cylindrical silos, but cannot meet the requirements of blowing the top and bottom of the silo, especially the requirements of cleaning conical silos. Therefore, it is necessary to develop a blowing device that can clean the entire inner wall of the silo to achieve rapid cleaning of the silo. Utility Model Content
