Description

Coal conveying anti-overflow multistage sealing guide chute

Technical Field

The utility model relates to a carry the technical field of auxiliary device, especially relate to coal conveying anti-overflow multistage sealed baffle box.

Background

As is well known, the powder leakage of a guide chute of a coal conveying system in domestic industry is a common problem, the dust emission during the operation of the guide chute is large, the dust quality standard (8mg/m3) of a working site specified by the state cannot be met, and the potential safety hazard is large. To dustproof modes such as negative pressure dust pelletizing system, spraying, fender powder curtain of adopting more of baffle box system in the current trade solve the raise dust problem, have following problem:

1. the tail part of the existing material guide groove is sealed and is in a simple straight cylinder shape, so that the coal powder can not be effectively sealed when the material falls, and more dust is generated;

2. the existing guide chute has an unreasonable structure, the buffer space inside the guide chute is insufficient, and the dust movement space cannot be well sealed, so that the situation that materials overflow from two sides of the guide chute is serious, and a large amount of dust is formed in a belt corridor;

3. the existing guide chute wear-resistant liner plate and the anti-overflow skirt edge have poor use effects, so that the material scattering and leaking are serious, and a large amount of dust overflows.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a coal conveying anti-overflow multistage sealed baffle box effectively restraines the emergence that the raise dust is big and buggy secondary raise dust during the baffle box operation.

The utility model discloses a multistage sealed baffle box of coal conveying anti-overflow, including the baffle box body, the baffle box body includes the mother board and installs two sets of curb plates in mother board bottom both sides, is provided with multistage labyrinth on two sets of curb plates and presses down dirt air curtain, and baffle box body afterbody is provided with the afterbody seal box, all is provided with double-deck anti-overflow shirt rim on two sets of curb plates, and baffle box body inner wall is provided with wear-resisting welt, and baffle box body export and afterbody seal box afterbody install the tip with keeping off the curtain cooperation additional and seal.

Compared with the prior art, the beneficial effects of the utility model are that: the newly-increased 150mm height of both sides curb plate of baffle box body, promote baffle box buggy buffering space, increase wear-resisting lining plate thickness simultaneously, baffle box side overflow limit crowd adopts double-deck anti-overflow shirt rim to seal, combine baffle box body length, inside every 450mm-550mm scope, install multistage dirt wind curtain additional, multistage dirt wind curtain install the motion route that can prolong the dust additional, let its energy decay, subside naturally, it is sealed to install tip fender curtain cooperation additional at baffle box afterbody and afterbody seal box afterbody export of baffle box body 1 simultaneously, the afterbody seal box cushions the malleation of the whirl formation of blanking mouth, prevent the external leakage that the high atmospheric pressure that the big air whirl of afterbody arouses from producing.
