Background technology
The dusty gas that Low-Pressure Pulse Bag Filter is mainly used for the industries such as metallurgy, electric power, building materials purifies, and dust settling pocket
It is the core component of deduster, is directly related to the dust removing effects of deduster.The dust settling pocket being commonly used is mainly by bag body
With bag cage form, wherein bag body is usually the cylindrical shape cloth bag (both ends equal diameter) that one end open one end is not open, according to containing
The characteristic and working condition of dust and gas body, this dust settling pocket service life is about in 1.5-2.For the cylindrical shape dust removing cloth
Bag, on the surface thereof, dust below is to the supporting role that produces above, thus dust is difficult to take off naturally by gravity when deashing
It falls, there are the halfway defects of deashing.
Application No. is 201020549287.0 utility model patents to disclose a kind of dedusting for bag-type dust collecting equipment
Bag, by the way that bag body is designed as taper or taper type bag body, and the open end diameter of the bag body is more than sealing end diameter, energy
It is enough fully so that the dust being attached on bag body is fallen off by gravity, to overcome the halfway defect of prior art deashing.But
The dust removing effects of above-mentioned dust settling pocket are not ideal enough, and the effect for making dust land only by improved shape is limited, can still cause
The accumulation of dust on dust settling pocket is easy to lump on dust settling pocket when with moisture, leads to dedusting especially when gas flow temperature is relatively low
Efficiency reduces.
Utility model content
The technical problems to be solved in the utility model is exactly to overcome above-mentioned the deficiencies in the prior art, and provide a kind of deashing effect
Fruit is good, and the self ash-cleaning type dust settling pocket that cleaning efficiency is high.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
Design a kind of self ash-cleaning type dust settling pocket, including bag cage and the dust settling pocket being set on the outside of the bag cage, the bag cage
Including support portion and the deashing portion being arranged inside the support portion, the support portion is in up big and down small cone cage shape structure, institute
It is up-small and down-big cone tubular structure to state deashing portion, and deashing portion upper end closed, lower end is opening；The side wall in the deashing portion
Upper circumferential direction is laid with multiple spray-holes；Wind pushing mechanism is equipped in deashing subordinate end at center.
Preferably, in above-mentioned self ash-cleaning type dust settling pocket, the support portion include the perpendicular support of be arranged circumferentially multiple and on
Under multiple stulls disposed in parallel, wherein stull both ends are connected in perpendicular support and deashing portion.
Preferably, in above-mentioned self ash-cleaning type dust settling pocket, the wind pushing mechanism is mounted on seat board, which passes through week
It is connected to the multiple spokes being arranged radially with deashing subordinate end.
Preferably, in above-mentioned self ash-cleaning type dust settling pocket, the wind pushing mechanism is breeze fan.
Preferably, in above-mentioned self ash-cleaning type dust settling pocket, all side walls of the axial line of the spray-hole and the bag cage
It is perpendicular.
The advantageous effects of technical solutions of the utility model are：
The utility model provides a kind of self ash-cleaning type dust settling pocket, using the deashing portion of cone cylinder shape, and generates sending for air-flow
Wind mechanism is gradually reduced, air pressure meeting after entering to deashing portion for the air-flow of deashing since deashing cross section is bottom-up
It gradually increases, air-flow after supercharged is projected by spray-hole on the dust settling pocket that after-blow is adhered to on support portion, and dust settling pocket is made to generate
Fluctuation is to make to be attached to the dust on its surface to be shaken off, and compared with the existing technology, dust falls by dead weight, then substantially increases clear
Grey efficiency and ash-removal effect.
In addition, wind pushing mechanism set by the utility model can further increase the wind pressure in deashing portion, deashing is further increased
Effect, and wind pushing mechanism can cause negative pressure in rotation to the bottom of support portion, keep the external wind containing dust quicker
Ground is by dust settling pocket, to reduce the pressure of supply air system.

Specific implementation mode
Below in conjunction with the accompanying drawings, a specific implementation mode of the utility model is described in detail, it is to be understood that this
The protection domain of utility model is not restricted by specific implementation.
As shown in Figures 1 to 5, a kind of self ash-cleaning type dust settling pocket that the utility model embodiment provides, including bag cage and set
The dust settling pocket 1 being located on the outside of bag cage.
Wherein, bag cage includes support portion 2 and the deashing portion 3 that is arranged inside support portion.And support portion is in up big and down small
