Description

Material prevents stifled quick-witted returning wind and presses down dirt sealing device

Technical Field

The utility model belongs to the technical field of anti-blocking machines, and particularly relates to a material anti-blocking machine air return dust suppression sealing device.

Background

The material breakage caused by material blockage of a stock bin or a pipeline in the process of conveying the dust materials is always a common problem which troubles related enterprises such as coal-fired power generation and the like, so that the labor and material resources are greatly wasted, and the material conveying is interrupted and the production is stopped if the material is heavy. The raw material anti-blocking machine is generally used at present because the raw material anti-blocking machine can effectively solve the problems of bonding and blocking of a storage bin and a pipeline. The structure of the material anti-blocking machine comprises an upper fixed cylinder, a lower fixed cylinder, a rotating body, a scraper, a power system and the like. When the scraper cleaning machine works, the power system drives the rotating body to rotate, and the rotating body drives the scraper to rotate, so that the adhered materials on the bin wall or the pipe wall are removed, and the materials are guaranteed to fall and circulate smoothly.

The connecting part of the fixed cylinder and the rotary bin needs to be sealed, so that the materials are prevented from leaking in the circulating process. Most of the existing sealing methods for dust materials comprise labyrinth sealing, flexible gasket sealing, packing sealing and the like. The sealing structure is worn quickly due to the friction of dust, and the sealing materials can be worn to cause leakage after being used for a period of time. In particular, in a coal-fired power generation or heat supply unit, positive pressure air generally exists in a coal dropping pipe of a hearth, a coal dropping pipe of a coal mill and a coal bunker, and the sealing structures are abraded more quickly and more seriously under the pressure in the bunker or the pipe, so that serious environmental pollution is caused.
