Dedusting equipment and method for fixed-point unloading movable dumper

Abstract

The invention relates to the technical field of unloading and dedusting bulk materials, in particular to dedusting equipment and a dedusting method for a fixed-point unloading movable dumper. The equipment comprises a central control room movable dumper, a feeding groove, a storage bin, a hanger plate, an electromagnet, a lower seat, a guide rod and a telescopic dustproof cover, wherein an automatic control system, a dumper encoder, two frequency conversion driving devices, two driving wheels with reverse taper directions, a feeding groove encoder, a level gage, a dustproof cover on the upper side of the feeding groove, an outer barrel in an inverted funnel shape, an inner barrel in a funnel shape, and rigid sealing strips are arranged in the movable dumper. The dedusting method comprises the following steps that: a central control room operates the movable dumper to move, align, stop, unload and move away through the automatic control system on the movable dumper according to information transmitted by the level gage in each storage bin. Through the invention, energy is saved and emission is reduced when the movable dumper unloads materials, automatic control is convenient to realize, the working efficiency of the equipment is improved, the working environment of a worker is improved, and investment is saved.

Description

technical field [0001] The invention relates to the technical field of unloading and dedusting of bulk materials, in particular to a fixed-point unloading and dedusting equipment for a mobile unloading vehicle and a dedusting method thereof. Background technique [0002] At present, mobile unloading vehicles are widely used in metallurgy, mining, chemical industry and other industries. The mobile unloading truck is used for multi-point unloading on the top of the silo. Due to the large drop in feeding, the opening of the silo is open, causing dust to fly during unloading, which seriously pollutes the working environment and endangers the health of workers, especially when unloading. Contamination is especially serious when drying fine materials. [0003] There is a steel support on the silo platform, and the unloading vehicle moves along the track on the support. There are silo openings on both sides of the track, but the form of the silo opening is different. One is t...

AI Technical Summary

Problems solved by technology

Regardless of the form, when unloading, the amount of dust in the corridor is very large. If indoor ventilation or dust collection at the silo opening is used to remove dust, due to factors such as the open silo opening and the large dust suction space, a large air volume must be set. Advanced ventilation and dust removal facilities not only consume a lot of energy, but also have a series of problems such as large floor area, high investment and operating costs
