Problems solved by technology

However, the existing disc-type ash unloading valve lacks a self-sealing function, such as a rotary disc-type scraper ash unloading machine disclosed in Chinese patent (CN103287846A), which can only realize the ash unloading function, but cannot realize the sealing function while unloading the ash

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] like figure 1 and figure 2 The shown self-sealing double-layer horizontal rotary disc dust discharge valve includes an inverted conical shell 10, the lower end of which is sealed and fixed to the lower sealing disc 4, and the lower sealing disc 4 has a lower sealing disc feeding port 41, a rotating shaft 5 penetrates into the casing 10 from the center of the lower sealing disc 4, and a transmission rod 13 cooperates with the rotating shaft 5, so that the rotating shaft 5 can rotate around its own center line. There is a shaft sleeve 51 on the outer ring of the rotating shaft 5, and the The centerline coincides with the centerline of the rotating shaft 5;

[0033] There is a lower rotary disk 3 on the upper side of the lower sealing disk 4, the center of the lower rotary disk 3 is sealed and fixedly connected with the rotating shaft 5, and the lower rotary d...

Abstract

The invention relates to a self-sealing double-layer horizontal rotary disk cinder valve which comprises an obconical shell (10), an upper and lower rotary disks (1, 3) installed on a rotating shaft (5), an upper sealing disk (2) positioned on the lower side of the upper rotary disk (1), and a lower sealing disk (4) positioned on the lower side of the lower rotary disk (3), wherein the upper sealing disk (3) and the lower sealing disk (4) are fixed to the shell (10). The superposition between an upper rotary disk feed opening (11) and an upper sealing disk feed opening (21) and the superposition between a lower rotary disk feed opening (31) and a lower sealing disk feed opening (41) do not occur simultaneously; and the cinder valve can implement alternate plugging on the feed openings of the upper and lower sealing disks (2, 4) on the premise of implementing alternate cinder discharge, thereby implementing the self-sealing function. The cinder valve has the advantages of high appearance taper degree and small space structure, is beneficial to implementing miniaturization on the dust removing plant, ensures the sealability in the cinder discharge process, is easy for mounting and operation, and is stable and reliable.

Description

technical field [0001] The invention relates to an ash unloading valve, in particular to a disc type ash unloading valve with a self-sealing function, which belongs to the technical field of environmental protection dust removal valves. Background technique [0002] The ash unloading valve is the main component of dust removal equipment, material conveying and other equipment feeding, and it is widely used in mining, electric power, cement and other industries. The dust removal equipment installs a dust discharge valve at the dust discharge port to control the dust discharge. The ideal dust discharge valve should not only ensure effective dust discharge, but also prevent external air from being sucked into the dust removal system through the dust discharge valve. During the operation of the dust removal equipment, once the dust discharge valve leaks, it will not only damage the internal flow field of the dust removal system, cause serious "secondary dust", and even lead to t...
