Description

Ash discharging device for dust collector

Technical field

The utility model relates to a kind of industrial dedusting equipment, is specifically related to a kind of ash discharging device for dust collector of cleaner.

Background technology

Cleaner is facility conventional in boiler and industrial production, its Main Function is that dust is separated from flue gas, ash exhauster is used under the ash bucket of cleaner, requires the dust stratification regularly or regularly got rid of in ash bucket, to ensure the normal operation of cleaner according to setting.Ash exhauster requires that operation should flexibly and air-tightness is good, be ensure air-tightness usually, needs the ash of keeping certain height to form ash envelope during ash discharge above ash quarrel.

The mode adopting the direct shutoff ash discharging hole of cover plate in prior art more, such as a kind of dual power automatic open close ash-valve, comprise cylindrical shell, blast pipe and exhaust duct, the bottom of cylindrical shell has ash discharging hole, ash discharging hole place is provided with ash exhauster, ash exhauster comprises, lower two gravity automatic open close ash-valves, each gravity automatic open close ash-valve has ash inlet and ash port respectively, the ash inlet being positioned at the gravity automatic open close ash-valve of top is connected with the ash discharging hole of cylindrical shell bottom, the ash port being positioned at the gravity automatic open close ash-valve of top is connected with the ash inlet of the gravity automatic open close ash-valve being positioned at below, each gravity automatic open close ash-valve comprises an ash bucket respectively, ash port is positioned at each ash bucket bottom, each ash bucket top is respectively equipped with cover plate, the middle part of each cover plate is vertically fixed with ash discharging cylinder respectively, ash discharging cylinder is rectangular tube, ash inlet is positioned at the top of each ash discharging cylinder, the cover plate of this kind of form only plays simple plugging action, and once ash discharge, cause because dust gets lodged near cover plate, it is good not to close, easy gas leakage.

Summary of the invention

The purpose of this utility model is to provide a kind of simple structure, automatic removing dust and the ash exhauster of good sealing effect.

To achieve these goals, the utility model provides a kind of ash discharging device for dust collector, include the flue-dust retainer be connected to below deduster, flue-dust retainer is tapered, described flue-dust retainer outlet is arranged straight down, an ash bucket is provided with below it, described ash bucket is U-shaped pipe, the import of ash bucket and flue-dust retainer export and abut against, the outlet of ash bucket is lower than its import, the side sidewall that ash bucket import exports away from ash bucket is fixed with a lever, the other end of lever is provided with a counterweight, the moment that counterweight produces is greater than ash bucket and internal dust produces moment.

The feature of technique scheme is: owing to have employed the mode that flue-dust retainer and ash bucket combine, ash bucket is similar to U-shaped pipe linker, for keeping balance after flue-dust retainer falls into dust, ash bucket will discharge the dust of equivalent, automatic removing dust is effective, and period is in by the state of ash bucket dust seal all the time, structure is simple too compared to the mode of traditional cover plate shutoff flue-dust retainer, the more important thing is when ash bucket blocking is abnormal, dust accumulation in flue-dust retainer can increase the moment of ash bucket one end, ash bucket is moved downward, automatically be separated with flue-dust retainer, realize the mode being similar to traditional cover plate shutoff, strengthen the gradient of ash bucket simultaneously, discharge part dust wherein, remove blocking, and the dust in flue-dust retainer is when being not enough to make the moment of ash bucket one end be greater than Balance weight end, ash bucket and flue-dust retainer recombine.

Preferably, in order to allow dust more easily ash bucket discharge, and ash bucket also can ash discharge when ash bucket tilts, and the outlet of described ash bucket is tilted to ash discharge direction.

Preferably, in order to make the sealing effectiveness of ash bucket and flue-dust retainer contact position better, described ash bucket import goes out to be provided with a rubber seal.

Preferably, in order to ensure can to have in flue-dust retainer the ash of enough height to form sealant, and again can ash discharge in time, the moment of preferred described counterweight generation is ash bucket and internal dust thereof produces 2 times of moment.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

As depicted in figs. 1 and 2: the utility model embodiment provides a kind of ash discharging device for dust collector, include the flue-dust retainer 1 be connected to below deduster, flue-dust retainer is tapered, flue-dust retainer 1 exports and arranges straight down, an ash bucket 2 is provided with below it, ash bucket 2 is the metal tube of U-shaped, its inner surface is provided with polytetrafluorethylecoatings coatings, with the raising wearability that reduces friction, the import of ash bucket 2 and flue-dust retainer 1 export and abut against, in order to make ash bucket 2 better with the sealing effectiveness of flue-dust retainer 1 contact position, ash bucket 2 import goes out to be provided with a rubber seal, the outlet of ash bucket 2 is lower than its import, in order to allow dust more easily ash bucket 2 discharge, even if it still also can ash discharge when making ash bucket 2 tilt, the outlet of ash bucket 2 is tilted to ash discharge direction, the side sidewall that ash bucket 2 import exports away from ash bucket 2 is fixed with a lever, the fulcrum 3 of lever is near ash bucket 2, lever is provided with a counterweight 4 away from one end of fulcrum 3, the moment that counterweight 4 produces is greater than ash bucket and moment that internal dust produces thereof, in order to ensure that the ash that can have enough height in flue-dust retainer 1 forms sealant, and again can ash discharge in time, 2 times of the moment that counterweight 4 produces to be ash bucket 2 and internal dust thereof produce moment, the position of counterweight 4 and size can adjust as required.

Its operation principle is as follows: because ash bucket 2 is similar to U-shaped pipe linker, can extrude the dust of ash bucket 2 after flue-dust retainer 1 falls into dust, and for keeping balance, ash bucket 2 can discharge the dust of equivalent usually; When there is blocking in ash bucket 2, dust accumulation in flue-dust retainer 1 can increase the moment of ash bucket 2 one end, ash bucket 2 is moved downward automatically be separated with flue-dust retainer 1, now dust is directly discharged from flue-dust retainer 1, the outlet of ash bucket 2 is simultaneously tilted more, also the dust discharging blocking when and dust in flue-dust retainer 1 is not enough to make the moment of ash bucket 2 one end be greater than counterweight 4 end time, ash bucket 2 and flue-dust retainer 1 recombine, and restPose.

Above-described is only preferred embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
