A quick-change dust-proof telescopic soft cover for a ship loader

Abstract

The invention relates to an environment-friendly dustproof device for ship loading, in particular to a fast-to-replace dustproof telescopic soft cover for a ship loader. The fast-to-replace dustproof telescopic soft cover comprises a square cloth outer sleeve, wherein self-adhesion belts are arranged on the two opposite side edges of the cloth outer sleeve, and are mutually pasted for rolling the cloth outer sleeve into a round tube shape with upper and lower openings, the upper end opening part and the lower end opening part of the cloth outer sleeve are respectively and fixedly provided with annular channel steel hoops, an annular telescopic slide tube inner clamp hoop is fixedly arranged on the inner surface of the cloth outer sleeve, an annular telescopic slide tube outer clamp hoop is arranged on the outer surface of the cloth outer sleeve, a groove is formed in the inner annular surface of the telescopic slide tube outer clamp hoop, and the telescopic slide tube inner clamp hoop is arranged in the groove. The fast-to-replace dustproof telescopic soft cover has the beneficial effects that the cloth outer sleeve can be conveniently replaced when the cloth outer sleeve is damaged, the production halt time is reduced, the work intensity of workers is reduced, the production efficiency is improved, and the problem of all-around spreading dust pollution phenomenon due to negative loss since a soft cover is inconvenient to replace after being damaged is solved.

Description

technical field [0001] The invention relates to an environmental protection dustproof device for shipping, in particular to a quick-change dustproof telescopic soft cover for a shipping machine. Background technique [0002] When loading cement, clinker, fly ash, slag, coke, grain, etc. at the wharf, double-layer telescopic chute must be used to ensure that the material is dropped to the cabin through the inner steel chute during the loading machine, and when the material falls, the The dust is directly recycled into the dust collector through the outer sealing telescopic soft cover to reduce or prevent dust pollution. [0003] The dust-proof telescopic soft cover is easily scratched during shipment. Because the telescopic soft cover must be able to expand and contract at any time and the weight can not be too heavy, it can only be made of soft materials, and the telescopic chute cover is formed according to the extension length and the stroke after multi-section connection...

AI Technical Summary

Problems solved by technology

When replacing, the telescopic chute must be completely dismantled by a car crane, and then the soft cover should be put on one by one. Each replacement must stop production for one to two days, which is time-consuming, labor-intensive and laborious; sometimes the soft cover is damaged even if only one The section will also lose pressure and produce a large amount of dust, which must be stopped and replaced in time, which will affect production and pollute the environment

At the same time, when the two sections of the soft cover are connected, the channel steel clamp is used to easily accumulate material, which will form a hard block after being damp, which will cause the chute to increase in weight or become unbalanced, and the soft cover will burst.
