Novel cross-beam chain grate

Abstract

The invention discloses a novel cross beam chain grate, mainly comprising a grate base, a front axle, a sprocket wheel, a plenum chamber, a fire grate back roller, a fire grate and a cross beam on which a fire bar can be mounted. The cross beam of the invention is provided with a rectangular fire bar of which both ends are provided with axles; the plenum chamber adopts the design of the even air supply. Compared with the prior fire bar, in the condition of same area, the rectangular fire bar of which both ends are provided with axles is much less in number and weight, thereby the invention has the advantages of saving materials, labor and time, along with easy assembly; because the plenum chamber adopts the design of the even air supply to supply air to the coal bed, the combustion efficiency is improved; moreover, because the invention adopts a plurality of patent technologies such as the anti-coal leak fire bar, the anti-air leak and anti-channeling air chamber and the novel layering coal feeding bucket, etc., the novel cross beam chain grate of the invention must achieve the best firing effect and improve the efficiency of the matching boiler to a maximum extent.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a beam chain grate for a chain grate boiler. technical background [0002] The crossbeam of the existing crossbeam chain grate is equipped with many small grates, and the dovetail groove structure is adopted to install the T-shaped iron on the crossbeam. The segmented air supply chamber of the beam chain grate is a relatively long rectangular ventilating body. Regardless of whether the air is supplied from one end or from both ends, the air is unevenly supplied to the grate and the coal seam, which affects the combustion effect of the coal. Contents of the invention [0003] The present invention provides a novel beam chain grate which overcomes the above-mentioned disadvantages. [0004] The present invention is realized like this: novel crossbeam chain fire grate, main part is made up of fire grate base, front axle, sprocket wheel, blower chamber, fire grate rea...

AI Technical Summary

Problems solved by technology

[0002] There are many small grates on the beam of the existing beam chain grate, and the T-shaped iron installed on the beam with a dovetail groove structure. This structure uses more materials to increase the weight of the grate, and it takes a lot of work and time to replace the grate.

The segmented air supply chamber of the beam chain grate is a relatively long rectangular ventilation body, no matter whether the air is supplied from one end or from both ends, it is unevenly supplied to the grate and the coal seam, which affects the combustion effect of the coal
