Description

Warehouse pump ash removal system Technical Field The invention relates to the technical field of pneumatic conveying equipment, in particular to a bin pump ash removal system. Background The bin pump is used as core equipment of a pneumatic conveying system, is widely applied to the fields of industrial dust removal, material conveying and the like, and has the main functions of temporarily storing and collecting dust and conveying the dust to a designated position through high-pressure gas. Traditional storehouse pump ash handling system generally includes storehouse pump body, feeding subassembly, air inlet unit, charge level indicator subassembly, pressure detection subassembly, exhaust subassembly, fluidization subassembly and ejection of compact pipe fitting isotructure, receives the dust through feeding subassembly, and air inlet unit provides the delivery pressure, and fluidization subassembly assists the fluidization of dust, finally realizes the discharge and the transportation of dust through ejection of compact pipe fitting and ejection of compact valve subassembly. In the existing bin pump ash removal system, anti-blocking measures are carried out by blowing operation mostly depending on a fluidization plate arranged at the bottom of the bin pump, and air flow is introduced into the bin through the fluidization plate to fluidize dust at the bottom so as to improve the fluidity of the dust. In the practical application process, the powder particles are influenced by mutual extrusion and adhesion, and when the powder is temporarily stored and conveyed in a bin pump, compaction and caking are easy to form, so that the powder fluidity is obviously reduced. The anti-blocking mode of upward blowing of the bottom fluidization plate is only relied on, and under the working condition that the dust is compacted, the method has obvious limitation that when the dust is compacted to form a compact structure, the fluidization plate air flow is difficult to penetrate through a compacting layer, and the bottom dust can be further compacted, so that the dust is more difficult to discharge from a discharge hole, and the discharge efficiency is seriously influenced. This compaction situation can prevent the dust from falling normally, resulting in a continuous accumulation of dust in the bin, further exacerbating the discharge difficulties. Meanwhile, the combination relation among dust particles cannot be fully destroyed by unidirectional air flow, caking cannot be effectively broken, massive dust is easy to drop, and then blockage is formed in a discharging pipe fitting and a subsequent conveying pipeline, so that the conveying flow can be interrupted, equipment shutdown can be possibly caused, and maintenance cost and production interruption risk are increased. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a bin pump ash removal system, which solves the technical problems that the traditional bin pump is easy to cause dust compaction, discharge blockage and low conveying efficiency by only spraying by virtue of a bottom fluidization plate, realizes efficient scattering and compaction blockage prevention of dust, and improves the operation stability and reliability of the bin pump ash removal system. In order to achieve the above purpose, the present invention adopts the following technical scheme: The utility model provides a storehouse pump ash handling system, includes the storehouse pump and establishes feeding subassembly, air inlet unit, charge level indicator subassembly, pressure detection subassembly, exhaust subassembly, fluidization subassembly and ejection of compact pipe fitting on the storehouse pump, be provided with ejection of compact valve subassembly on the ejection of compact pipe fitting, storehouse pump lower extreme discharge end links to each other with ejection of compact pipe fitting through the ring flange, still be equipped with anti-blocking assembly on the storehouse pump, establish the rotatory rotary blowing mechanism of air current drive in the anti-blocking assembly, rotary blowing mechanism disposes the shower nozzle of giving vent to anger along with its pivoted, the shower nozzle spun air current of giving vent to anger cooperatees with fluidization subassembly's blowout air current, realizes that the dust breaks up and prevents the compaction jam.
