Dust removing cloth bag for coal charging car

Abstract

The invention discloses a dust removing cloth bag for a coal charging car. The dust removing cloth bag for the coal charging car comprises an outer bag body, an inner bag body and a skeleton, wherein a secondary air flow passage is formed between the outer bag body and the inner bag body in an annulus manner; the upper end of the outer bag body is provided with an air outlet connected with the secondary air flow passage; a barrel is mounted between the bottom of the inner bag body and the bottom of the outer bag body; an open end of the barrel is communicated with the inside of the inner bag body; two side walls of the barrel are both provided with air holes communicated with the secondary air flow passage; a sliding block is arranged in the barrel in a sliding manner; the bottom of the sliding block is provided with a spring. Acting stress generated during the secondary expansion of the outer bag body is far more than acting stress generated during the primary expansion of the outer bag body, so that mill dust adhered to the outer bag body is completely popped out; in comparison with a dust removing cloth bag with a single-layer structure, the dust removal efficiency of the dust removing cloth bag for the coal charging car is greatly improved; moreover, the expansion of the outer bag body is driven by the expansion of the inner bag body; the direct scour carried out directly on the outer bag body by an air current is decreased; furthermore, the loss of the outer bag is decreased.

Description

technical field [0001] The invention relates to the field of bag dust removal, in particular to a dust removal bag used for coal loading vehicles. Background technique [0002] Environmental protection has become a crucial link in industrial development, and the investment in environmental protection equipment will also become a large proportion, which will bring great financial pressure to users. The existing dust bag is a drum single-layer structure, which is easy to process. It is a form commonly used in the existing market, but because of its large size, the equipment manufacturing cost increases, the operating cost is too high, and the single-layer structure has a general filtering effect and a short service life. Moreover, the cloth bag is easy to fold due to the long-term impact of the gas during the collection process, thereby affecting the filtration area of ​​the filter cloth bag, and then affecting the filtering effect of the filter cloth bag.
