Abstract
The utility model relates to a dust-removing device, in particular to a boiler slag hole dust-removing device. The boiler slag hole dust-removing device comprises a conveyer belt which is connected with a slag hole, and a dust-absorbing cover is fixed on the conveyer belt, the dust-absorbing cover is located at the connecting position between the slag hole and the conveyer belt. The boiler slag hole dust-removing device further comprises a dust-absorbing pipe, wherein one end of the dust-absorbing pipe is connected with the tail portion of a boiler, and the other end of the dust-absorbing pipe is connected with the dust-absorbing cover. The boiler slag hole dust-removing device has the advantages of being capable of effectively absorbing flying dust when boiler slag falls down, reducing the splashing range of the flying dust and improving site environment, low in cost and the like.
Description
Technical field
The utility model relates to a kind of dust arrester, especially relates to a kind of boiler slag notch dust arrester.
Background technology
The existing boiler mode of slagging tap is that the slag in the boiler is delivered in the slag storehouse by conveyer belt, but owing to have difference in height between slag notch and the conveyer belt, causes airborne dust easily when slag is fallen on the conveyer belt, causes site environment relatively poor.
As the Chinese patent publication number be: CN101603690A, in disclosed a kind of follow-on biomass straw boiler slag discharge hole structure on December 16th, 2009, the slag that falls behind its boiler adopts same outlet with the ash that falls, the described cinder notch that falls is arranged at boiler burning chamber bottom, described ash port is arranged at boiler convection pass bottom, and fall cinder notch and ash port lower end are equipped with the ash discharge slag bucket.But owing to have difference in height between slag notch and the conveyer belt, when slag is fallen on the conveyer belt, cause airborne dust easily, cause site environment relatively poor.
The utility model content
The utility model mainly is when slagging tap at existing boiler owing to have difference in height, slag between slag notch and the conveyer belt and cause airborne dust easily when falling, cause problems such as site environment is relatively poor, provide a kind of can absorb slag effectively and fall the time airborne dust, dwindle scope that airborne dust splashes, improve site environment, boiler slag notch dust arrester that cost is low.
The purpose of this utility model mainly is achieved by following proposal: a kind of boiler slag notch dust arrester, comprise the conveyer belt that links to each other with slag notch, be set with dust shield on the described conveyer belt, dust shield is positioned at the junction of slag notch and conveyer belt, also comprise sweep-up pipe, an end of described sweep-up pipe links to each other with boiler tail, the other end links to each other with dust shield.Slag is discharged and is dropped on the conveyer belt by slag notch, fixedly mounts dust shield on conveyer belt, and the position of dust shield is positioned at the junction of slag notch and conveyer belt, is connected with sweep-up pipe on the dust shield, and the other end of sweep-up pipe is connected boiler tail.Boiler in use because the internal pressure at boiler tail place less than external pressure, promptly has negative pressure, so also has negative pressure in the sweep-up pipe.Sweep-up pipe with negative pressure sucks dust shield by the airborne dust that slag produced that dust shield will drop on the conveyer belt, and sucks sweep-up pipe by dust shield, is sucked the inside of boiler tail again by sweep-up pipe.Adopt the negative pressure of boiler internal self to adsorb the airborne dust that produces when slag is discharged, not only cost is low, and can dwindle scope that airborne dust splashes effectively, improves site environment.
As preferably, described sweep-up pipe is provided with valve.Mounted valve on sweep-up pipe is controlled the size of dust suction intraductal pressure by valve, and then controls the dynamics that absorbs airborne dust.
As preferably, described valve is a butterfly valve.Valve adopts butterfly valve, is convenient to operation, and cost is low.
As preferably, be connected with part flow arrangement on the described sweep-up pipe.Can connect part flow arrangement on the sweep-up pipe, can branch out a plurality of arms, a plurality of slag notches are carried out dust suction by part flow arrangement.
As preferably, described part flow arrangement is a three-way pipe.Part flow arrangement can be three-way pipe, is convenient to connect, and cost is low.
Therefore, boiler slag notch dust arrester of the present utility model possesses following advantage: 1, boiler in use, because the internal pressure at boiler tail place is less than external pressure, promptly has negative pressure, therefore also has negative pressure in the sweep-up pipe, sweep-up pipe with negative pressure sucks dust shield by the airborne dust that slag produced that dust shield will drop on the conveyer belt, and by dust shield suction sweep-up pipe, suck the inside of boiler tail again by sweep-up pipe, adopt the negative pressure of boiler internal self to adsorb the airborne dust that produces when slag is discharged, not only cost is low, and can dwindle the scope that airborne dust splashes effectively, improve site environment; 2, mounted valve on sweep-up pipe is controlled the size of dust suction intraductal pressure by valve, and then controls the dynamics that absorbs airborne dust; 3, can connect part flow arrangement on the sweep-up pipe, can branch out a plurality of arms, a plurality of slag notches are carried out dust suction by part flow arrangement.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, 2, a kind of boiler slag notch dust arrester comprises the conveyer belt 4 that links to each other with slag notch, is installed with dust shield 3 on the conveyer belt 4, dust shield 3 is positioned at the junction of slag notch and conveyer belt 4, and dust shield 3 adopts sheet iron to be made.Be connected with sweep-up pipe 2 between dust shield 3 and the boiler tail 1, an end of sweep-up pipe 2 links to each other with boiler tail 1, the other end links to each other with dust shield 3.Be connected with part flow arrangement 5 on the sweep-up pipe 2, part flow arrangement 5 is a three-way pipe.Valve 6 is installed on sweep-up pipe 2, and valve 6 is a butterfly valve.
Slag is discharged and is dropped on the conveyer belt by slag notch, fixedly mounts dust shield on conveyer belt, and the position of dust shield is positioned at the junction of slag notch and conveyer belt, is connected with sweep-up pipe on the dust shield, and the other end of sweep-up pipe is connected boiler tail.Boiler in use because the internal pressure at boiler tail place less than external pressure, promptly has negative pressure, so also has negative pressure in the sweep-up pipe.Sweep-up pipe with negative pressure sucks dust shield by the airborne dust that slag produced that dust shield will drop on the conveyer belt, and sucks sweep-up pipe by dust shield, is sucked the inside of boiler tail again by sweep-up pipe.Adopt the negative pressure of boiler internal self to adsorb the airborne dust that produces when slag is discharged, not only cost is low, and can dwindle scope that airborne dust splashes effectively, improves site environment.Mounted valve on sweep-up pipe is controlled the size of dust suction intraductal pressure by valve, and then controls the dynamics that absorbs airborne dust.Valve adopts butterfly valve, is convenient to operation, and cost is low.Can connect part flow arrangement on the sweep-up pipe, can branch out a plurality of arms, a plurality of slag notches are carried out dust suction by part flow arrangement.Part flow arrangement can be three-way pipe, is convenient to connect, and cost is low.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
