Abstract

The utility model provides an automatic keep apart and turn over board -like grey valve of putting, it includes two weights and two turn over the board, two are turned over board parallel mount and in the lower part of ash bucket, turn over the lateral wall that the ash bucket lower part was passed to the board level, turn over other lateral walls that the board is in the inboard adjacent ash bucket of part of ash bucket for the ash bucket is sealed, turns over the board and is the pole at the outside part of ash bucket, two weights set up respectively on two poles that turn over the board, lie in the outside of ash bucket, make to turn over the board and use the lateral wall that passes as fulcrum keep balance. The position is higher, and turn over the board and the weight is the first layer flap valve, and the position is lower, and turn over the board and the weight is a second floor flap valve, and its adopts the equilibrium principle of lever, simple structure, and low in cost has not only improved the security of putting grey equipment, has still effectively saved the station service, grey flow area is big in the automatic keep apart and turn over board -like grey valve of putting, is difficult for the deposition, and a small amount of inner wall deposition accessible strikes to be cleared up on line, and the effect is obvious, and the clearance is convenient.

Description

Automatism isolation slat belt ash-removing valve

Technical field

The utility model relates to one and puts grey equipment, particularly a kind of slat belt ash-removing valve adopting bilateral weight, i.e. a kind of automatism isolation slat belt ash-removing valve.

Background technique

In the industrial premises such as power station, cement plant, chemical plant; often a lot of dust can be produced in the flue of boiler; the superficial dust of boiler two, three flue and horizontal flue heating surface is purged by the shock wave soot blower being arranged on boiler both sides; the dust stratification dropped drops down onto the ash bucket of flue bottom; below ash bucket, electric lock pneumatic device is installed usually; ash passes through electric lock pneumatic device by even dispatch to hidden scraper conveyer, until be delivered to slag storehouse, transports outward process by automobile.In garbage incinerating power plant, ash bucket region is negative pressuren zone, and electric lock pneumatic device structurally can ensure sealing, but the grey viscosity of garbage incinerating power plant discharge is larger, equipment long-play can cause electric lock pneumatic device inwall dust stratification, and beating effect is not good in running, not easy to clean, if things go on like this, lower ash can be caused not smooth, finally make the inner dust stratification of ash bucket, ash bucket steel structure can be caused when dust stratification is serious to be out of shape, even affect the operation of enterprise's whole production line.Therefore, market is one not dust stratification urgently, or dust stratification easy to clean, and sealing puts grey equipment preferably, i.e. a kind of automatism isolation slat belt ash-removing valve.

Summary of the invention

Technical problem to be solved in the utility model overcomes above-mentioned existing ash bucket to put grey equipment---the deficiency of electric lock pneumatic device, and provide a kind of slat belt ash-removing valve adopting bilateral weight, i.e. a kind of automatism isolation slat belt ash-removing valve.

The technical scheme in the invention for solving the technical problem is: a kind of automatism isolation slat belt ash-removing valve, it comprises two weights and two turnover panels, described two turnover panels are installed in parallel in the bottom of ash bucket, turnover panel is horizontal through a sidewall of ash bucket bottom, turnover panel is in other sidewall of the adjacent ash bucket of part inside ash bucket, ash bucket is sealed, and the part that turnover panel is in ash bucket outside is bar; Described two weights are separately positioned on the bar of two turnover panels, are positioned at the outside of ash bucket, make turnover panel with the sidewall passed for fulcrum keeps balance.

This automatism isolation slat belt ash-removing valve provided by the utility model, the turnover panel that position is higher and weight are first layer Flap valve, the turnover panel that position is lower and weight are second layer Flap valve, it adopts the equilibrium principle of lever, first and second layer of Flap valve reset condition is all in state of equilibrium, i.e. closed condition, after dust stratification reaches constant weight, first layer Flap valve rotates and opens, after dust stratification falls to second layer Flap valve, first layer Flap valve rotates closes, in the process, second layer Flap valve is failure to actuate, in order to ensure tightness; Along with dust stratification deposition continues to increase, second layer Flap valve rotates to be opened, and to the defeated ash of scrapper conveyor, on turnover panel, dust stratification reduces, and then second layer Flap valve cuts out.

The counterweight of above-mentioned weight can regulate according to actual field situation.

This automatism isolation slat belt ash-removing valve provided by the utility model, structure is simple, cheap, not only increases the Security of putting grey equipment, also effectively saves station service; In automatism isolation slat belt ash-removing valve, grey circulation area is large, not easily dust stratification, and a small amount of inwall dust stratification carries out Hand scarf, successful by knocking, and cleaning is convenient.

Embodiment

Below in conjunction with embodiment, the utility model is described in further detail, but do not limit protection domain of the present utility model.

The utility model embodiment provides a kind of automatism isolation slat belt ash-removing valve, it comprises two weights 3 and two turnover panels 2, described two turnover panels 2 are installed in parallel in the bottom of ash bucket 1, turnover panel 2 is horizontal through a sidewall of ash bucket 1 bottom, turnover panel 2 is in other sidewall of the adjacent ash bucket 1 of part inside ash bucket, ash bucket 1 is sealed, and the part that turnover panel 2 is in ash bucket 1 outside is bar 4; Described two weights 3 are separately positioned on the bar 4 of two turnover panels 2, are positioned at the outside of ash bucket 1, make turnover panel 2 with the sidewall passed for fulcrum keeps balance.

This automatism isolation slat belt ash-removing valve provided by the utility model, the turnover panel 2 that position is higher and weight 3 are first layer Flap valve, the turnover panel 2 that position is lower and weight 3 are second layer Flap valve, it adopts the equilibrium principle of lever, first and second layer of Flap valve reset condition is all in state of equilibrium, i.e. closed condition, after dust stratification reaches constant weight, first layer Flap valve rotates and opens, after dust stratification falls to second layer Flap valve, first layer Flap valve rotates closes, in the process, second layer Flap valve is failure to actuate, in order to ensure tightness; Along with dust stratification deposition continues to increase, second layer Flap valve rotates to be opened, and to the defeated ash of scrapper conveyor, on turnover panel, dust stratification reduces, and then second layer Flap valve cuts out.
