Self-sealing type double-layer horizontal rotating disc dust-discharging valve

Abstract

The invention relates to the technical field of dust-discharging valves, and discloses a self-sealing type double-layer horizontal rotating disc dust-discharging valve, which comprises a dust-discharging valve body, a dust-discharging groove is formed in the top of the dust-discharging valve body, a first partition plate is fixedly mounted in the dust-discharging groove, a second partition plate located at the bottom of the first partition plate is fixedly mounted in the dust-discharging groove, the bottom of the dust-discharging valve body is fixedly connected with a discharging pipe communicating with the dust-discharging groove, the bottom of the discharging pipe is fixedly connected with a rotating motor, and an output shaft of the rotating motor is fixedly connected with a rotating shaft which sequentially penetrates through the dust-discharging valve body, the second partition plate and the first partition plate and extends to the top of the first partition plate. According to the self-sealing type double-layer horizontal rotating disc dust-discharging valve, the problems that a disc-type dust-discharging valve is simple in structure and small in occupied space, has high adaptability to the characteristics of dust and is wide in application range, however, the self-sealing performance of the existing disc-type dust-discharging valve is low, a sealing strip is abraded in the using process, and consequently, the sealing performance is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of ash unloading valves, in particular to a self-sealing double-layer horizontal rotary disc ash unloading valve. Background technique [0002] The dust discharge valve is the main component of dust removal equipment, material transportation and other equipment feeding. It is widely used in mining, electric power, cement and other industries. Dust removal equipment is equipped with a dust discharge valve at the dust discharge port to control the dust. Ideal The ash unloading valve must not only ensure effective ash discharge, but also prevent outside air from being sucked into the dust removal system through the ash unloading valve. During the operation of the dust removal equipment, once the ash unloading valve leaks air, it will not only damage the internal flow field of the dust removal system, causing serious "secondary secondary dust ", and even lead to the failure of the dust removal system. At present...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a self-sealing double-layer horizontal rotary disc ash unloading valve, which has the advantages of strong sealing and low maintenance frequency, and solves the problem that the disc ash unloading valve has a simple structure and takes up little space. , has strong adaptability to the characteristics of ash materials, and has a wide range of applications, but the existing disc-type ash unloading valve is not self-sealing, and the sealing strip will be worn during use, which will lead to the problem of reduced sealing performance.
