Coverage type belt conveyor dust cover assembly

Abstract

The invention provides a coverage type belt conveyor dust cover assembly. The coverage type belt conveyor dust cover assembly comprises a (1) keel arranged above a belt of a belt conveyor, (2) a dust cover plate covering the keel and fixedly connected to the keel, (3) a dust cover support fixedly connected to the keel and used for supporting the keel and the dust cover plate, and (4) sealing assemblies arranged at the edges of the two sides of the dust cover plate to keep elastic sealing contact of the dust cover plate and the belt of the belt conveyor. Compared with a commonly-used full wrapping type belt conveyor dust cover assembly at present, the coverage type belt conveyor dust cover assembly directly covers the belt of the belt conveyor, it is guaranteed that dust cannot be leaked to the maximum degree, and the potential safety hazard that explosion under a certain dust concentration is caused by possibly-generated sparks caused by rotation of a carrier roller of the belt conveyor is avoided; and meanwhile, overhauling and replacement of the belt of the belt conveyor and the other components are facilitated, and manpower and materials are obviously saved.

Description

technical field [0001] The invention relates to a belt conveyor dust cover assembly, in particular to a covered belt conveyor dust cover assembly. Background technique [0002] In recent years, in order to obtain better economic benefits, various thermal power plants across the country have blended a part of lignite. Due to the high volatile content of lignite in the air-dried base, the environment inside the transfer station and trestle bridge is extremely harsh, with low visibility, and a large amount of coal dust also brings great harm to the health of the on-site workers. At the same time, the ignition point of lignite is very low. After the belt conveyor runs for a long time, a large amount of coal dust accumulates, which can easily cause spontaneous combustion, which has brought a severe test to the on-site fire prevention work. [0003] At present, all-inclusive dust covers have been installed on the coal conveying belt conveyors of some thermal power plants to wrap ...

AI Technical Summary

Problems solved by technology

[0004] 1. The bottoms of the side covers on both sides are flush with the ground, so that the flushing water pipe cannot directly flush the ground under the belt, making it difficult to clean the ground under the belt

In order to wash under the belt, one side cover must be disassembled at intervals of several meters, and the side cover needs to be installed after washing, which adds unnecessary trouble to the cleaner's work;

[0005] 2. Wrapping the whole belt in manpower and material causes waste;

[0006] 3. The upper cover keel of the dust cover is welded by circular stainless steel square tube and straight stainless steel square tube. This process not only wastes labor, but also is difficult to control the stress deformation caused by welding, which may easily lead to There is a large deviation in size, resulting in uneven appearance of the product, which not only affects the sealing, but also brings difficulties to on-site installation;

[0007] 4. It is very inconvenient for daily inspection, maintenance and replacement of belt conveyor parts. Generally, the on-site stacking space is limited, and many bolts on the dust cover plate need to be dismantled one by one, and then moved to a suitable place at a certain distance. Reset the dust cover plate to its original state, maintenance personnel may not install it in place when resetting, and repeated disassembly may easily lead to damage;

[0008] 5. Occasionally, sparks will be generated between the metal parts of the rotating idler roller during operation, and it is easy to cause an explosion after contacting with a certain concentration of coal powder. At present, the power plant generally uses a hand-held concentration detector to conduct random spot checks, and it is impossible to check the belt. Real-time monitoring of the dust concentration inside, so there is a major safety hazard
