Dustproof device of hopper car

Abstract

The invention discloses a dustproof device of a hopper car, which comprises a hopper car main body (1) and a cloth bag opening (5), wherein the vertically downward cloth bag opening (5) is disposed at a hopper opening (2) of the hopper car main body (1), the cloth bag opening (5) is a flexible cloth bag with two communicated ends, and a sealing cover (6) is disposed on the mid-lower part. In the dustproof device of the hopper car provided by the invention, the cloth bag opening and the sealing cover are disposed at a discharge hole of the hopper car, the hopper car can be well connected with other equipment in a sealed manner by the sealing cover when materials inside a hopper falls to a feeding hole of the other equipment, so that dust at the discharge hole is avoided from flying into air when the materials in the hopper fall to the discharge hole of the other equipment, possibility in operators' contact with the dust is greatly reduced, physical health and safety of the operators are guaranteed, and the problem existing in the prior art that dust generated during falling of the materials in the hopper car flies around and influences the physical health and safety of people can be effectively solved. The dustproof device of the hopper car provided by the invention is also characterized by a simple structure, a cheap price and convenient utilization operations.

Description

technical field [0001] The invention belongs to the technical field of funnel design and relates to a dustproof device for a funnel car. Background technique [0002] Dust can not only cause occupational diseases and endanger human health, but also some combustible dusts, such as flour and coal powder, have the risk of explosion when they reach a certain concentration. At present, the raw materials used in many factories are fine powder, and many of them need to be mixed and put into the hopper car, transported to the designated discharge port, and the discharge switch plate is pulled to make it reach along the discharge port. machine, but because there is a certain distance between the discharge port of the hopper car and the discharge port, when the material is discharged, a lot of dust will float in the workshop, which seriously threatens the health and safety of workers. Contents of the invention [0003] The technical problem to be solved by the present invention is:...
