Abstract

The utility model discloses a settling-type ash hopper air inlet structure. The settling-type ash hopper air inlet structure comprises an ash hopper, wherein the ash hopper is provided with an air inlet pipe, one end of the air inlet pipe is connected with a reducer pipe, the air inlet pipe is connected with the ash hopper through the reducer pipe, a pipe orifice, communicated with the ash hopper, of the reducer pipe is in an irregular flared structure, the position, adjacent to the pipe orifice of the reducer pipe, of the inner wall of the ash hopper is fixedly provided with a framework positioning device in a welding manner, a framework rotating shaft is installed on the framework positioning device in a hinge manner, a framework is fixedly welded on the framework rotating shaft, a plurality of layers of guide plates are installed on the framework, and each guide plate is right opposite to the pipe orifice of the reducer pipe on the ash hopper. The settling-type ash hopper air inlet structure is ingenious in structure improvement, mainly applied to an air inlet of a dust collector ash hopper, can be used for pre-settling the large-particle dust and can well homogenize the inlet airflow.

Description

Sedimentation type ash bucket air inlet structure

Technical field

The utility model cleaner technical field is mainly a kind of sedimentation type ash bucket air inlet structure.

Background technology

At present, sack cleaner is in the time of design, because of the difference of smoke property and exhaust gas volumn, what a lot of dedusters adopted is all from ash bucket air intake, this project organization is simple, easy to maintenance, but some drawbacks are also there are in the process using, for example air intake air-flow wind speed is too fast or angle is improper, there will be the phenomenon of airflow scouring filter bag bottom, also can cause the service life of overall filter bag unbalanced, there is dead angle in indoor some position of bag even, without dust-filtering, also have a small amount of dust of ash bucket bottom storage that reentrainment of dust etc. also easily occurs.For this reason, also designed import deflector before, but be mainly to design the whole plate of a fritter at air inlet place, air-flow is stopped to changed course, this deflector does not have the effect of equal wind, and import wind speed is still too fast, the dynamics of the washing away minimizing to dust and filter bag is also not obvious, so need to study more preferably air intake flow-guiding structure of a kind of effect.

Utility model content

The purpose of this utility model is the deficiency in order to make up existing common sack cleaner ash bucket air inlet structure, the phenomenon such as too fast, the skewness of air-flow wind speed, reentrainment of dust during for ash bucket air intake, provides a kind of with sedimentation function and sedimentation type ash bucket air inlet structure that can uniform air-flow.

The technical solution adopted in the utility model is:

A kind of sedimentation type ash bucket air inlet structure, include ash bucket, ash bucket is provided with blast pipe, it is characterized in that: one end of described blast pipe is connected with a reducer pipe, described blast pipe is connected with described ash bucket by reducer pipe, described reducer pipe the is communicated with position mouth of pipe with ash bucket is irregular bell-mouth structure of air, on described ash bucket inwall, be fixedly welded with framework locator in the position near the reducer pipe mouth of pipe, the hinged framework turning cylinder that is provided with on described framework locator, on described framework turning cylinder, be fixedly welded with framework, multilayer deflector is installed on framework, described deflector faces the mouth of pipe of reducer pipe on ash bucket.

On described ash bucket inwall, the framework locator of fixing welding has two, and described framework turning cylinder is stuck between two framework locators and is articulated and connected with it.

The utility model middle frame is fixed with framework turning cylinder, and framework turning cylinder rotates and can drive multilayer deflector to rotate, and when turning to different angles, the angle of the gas shock deflector of coming in is just different, has also just reached different water conservancy diversion effect.

The utility model is on the basis of existing common ash bucket air inlet structure, adopt new technology, make the sedimentation type ash bucket air inlet structure after improving there is the effect of sedimentation bulky grain and uniform air-flow, wherein the air-flow in blast pipe is entering before ash bucket through reducer pipe, the mouth of pipe of reducer pipe is irregular horn mouth shape, flue gas is by after reducer pipe, wind speed is reduced to 1/3 original left and right, the enlarging of reducer pipe is located at below, meet and slip grey needs, and can make airflow direction change to oblique below, opposite, wherein multilayer deflector can be adjusted angle according to air-flow trend, air-flow is uniformly distributed, and have and stop oarse-grained effect, the dust that in flue gas, abrasion is stronger falls into ash bucket in advance, protect the bag end, and air-flow has also reached a kind of speed and all effects of balance of air quantity entering before bag chamber, make the load balancing of every filter bag, more balance is also incited somebody to action in the long-term operation of deduster.

The utility model has the advantages that:

The utility model architecture advances is ingenious, be provided with reducer pipe and can reduce wind speed, then impinge upon again on multilayer deflector, can carry out pre-sedimentation to oarse-grained dust, and air intake air-flow is carried out to preferably all wind, and deflector can rotate, when turning to different angles, the angle of the gas shock multilayer deflector of coming in is just different, thereby reaches different water conservancy diversion effect.

Detailed description of the invention

Referring to Fig. 1, 2, a kind of sedimentation type ash bucket air inlet structure, include ash bucket 1, ash bucket 1 is provided with blast pipe 2, one end of described blast pipe 2 is connected with a reducer pipe 3, described blast pipe 2 is connected with described ash bucket 1 by reducer pipe 3, described reducer pipe 3 the is communicated with position mouth of pipe with ash bucket 1 is irregular bell-mouth structure of air, on described ash bucket 1 inwall, be fixedly welded with framework locator 7 in the position near the reducer pipe mouth of pipe, the hinged framework turning cylinder 6 that is provided with on described framework locator 7, on described framework turning cylinder 6, be fixedly welded with framework 5, multilayer deflector 4 is installed on framework 5, described deflector 4 faces the mouth of pipe of reducer pipe 3 on ash bucket.

On described ash bucket inwall, the framework locator 7 of fixing welding has two, and described framework turning cylinder 6 is stuck between two framework locators 7 and is articulated and connected with it.

In operation, air-flow enters the process of ash bucket 1 from blast pipe 2, first pass through reducer pipe 3, reduce wind speed, impinge upon again on multilayer deflector 4 after entering ash bucket 1, big dust particle is settled down, multilayer deflector 4 is fixed on framework 5, and framework turning cylinder 6 drives framework 5 to rotate, thereby multilayer deflector 4 can adjust angle according to air-flow trend, and air-flow is uniformly distributed.
