Hopper bottom be provided with dust export, be additionally provided with controller on the cabinet, the controller connects electromagnetic impulse valve,
The electromagnetic impulse valve connects gas blow pipe, and the air inlet connects blast pipe, the blast pipe far from air inlet one
End is sealing structure, and the blast pipe is provided with variable diameter porous plate far from a side-lower of air inlet.
The length of the variable diameter porous plate accounts for about the half of entire air inlet length of tube, the height of the variable diameter porous plate
Degree is inwardly continuously increased from air inlet.
The height of the variable diameter porous plate is inwardly continuously increased from air inlet, and increasing angle is about 5 °.
Filter bag frame is provided with outside the dedusting filtering bag.
It is additionally provided with observation window on the cabinet, facilitates the filtering situation of observation box house.
(3) beneficial effect
(1) the utility model is provided with the structure of variable diameter porous plate using blast pipe far from a side-lower of air inlet, makes
Air inlet is uniformly distributed in ash bucket, and air inlet increases in the distance of dedusting filtering bag, and air inlet is made to have enough distances to slow down.
Gas is first downwardly into ash bucket after passing through air inlet, contacts dedusting filtering bag upwards from ash bucket, in this process,
The sectional area that gas passes through gently increases, and reduces gas flow rate gently, and the setting of variable diameter porous plate keeps front and back intake consistent
Uniformly, in the process, due to the reduction of speed, most of partial size is big, and the big particle of density is due to inertia and gravity
Directly sedimentation falls into ash bucket, and when dusty gas contacts dedusting filtering bag, speed is slowly uniform, and dustiness is reduced, and greatly improves and removes
The treatment effeciency of dirt device.
(2) it is provided with filter bag frame outside dedusting filtering bag, fixes filter bag shape, there is making for interests filter effect and filter bag
Use the service life.
Through actual use confirm, can make dedusting filtering bag service life extend 2 times or more, high concentration dedusting work in, formally
Dedusting filtering bag is without breakage in operating 30 days.

Specific embodiment
The technical solution of the utility model is understood in order to clearer, it is further to the utility model with reference to the accompanying drawing
Explanation.
A kind of pulse dust removal bag dust collector as shown in Figs 1-4 enters the wind current equalizer, including cabinet 1 and bracket 2, described
Cabinet 1 is provided with air inlet 3, net gas outlet 11, is internally provided with card 14 in cabinet 1, the card 14 connects dedusting filtering bag
7, the bottom of box is provided with ash bucket 12, and 12 bottom of ash bucket is provided with dust export 13, is additionally provided with control on the cabinet 1
Device 8 processed, the controller 8 connect electromagnetic impulse valve 10, and the electromagnetic impulse valve 10 connects gas blow pipe 15, the air inlet
Mouthfuls 3 connect blast pipes 4, and the one end of the blast pipe 4 far from air inlet 3 is sealing structure, and the blast pipe 4 is far from air inlet
A side-lower be provided with variable diameter porous plate.The length of the variable diameter porous plate account for about entire 4 length of blast pipe two/
One, when practical application, 4 length 2300mm of blast pipe, the length of variable diameter porous plate is about 1200mm, the height of the variable diameter porous plate
Degree is inwardly continuously increased (specific as shown in Figure 2) from air inlet 3.The height of the variable diameter porous plate from air inlet inwardly not
Disconnected to increase, increasing angle is about 5 °.Filter bag frame 6 is provided with outside the dedusting filtering bag.It is additionally provided on the cabinet 1
Observation window 9 facilitates the filtering situation of observation box house.
Working principle:
Dusty gas enters filter chamber by blast pipe.Granule dust in dusty gas is into prominent due to wind speed in ash bucket
So decline, the large dust particle in dusty gas directly falls after natural subsidence occurs, remaining dust enters cabinet mistake with air-flow
Filter area.
Dust collector box body filtering area top is provided with card, and the filter bay assembly of deduster is sealed using spring piston ring and card
Connection, dusty gas penetrate filter bag under the action of negative pressure in cabinet, and dust is stopped by filter bag, are adsorbed on the outer surface of filter bag,
Filtered clean gas penetrates filter bag and exports discharge through net gas.
The air inlet current equalizer is additionally provided with controller, and controller connects electromagnetic impulse valve, and the connection of electromagnetic impulse valve 10 is blown
Tracheae realizes that pulse automatically controls.
Blast pipe is provided with the structure of variable diameter porous plate far from a side-lower of air inlet, and air inlet is made uniformly to be distributed in ash
In bucket, air inlet increases in the distance of dedusting filtering bag, and air inlet is made to have enough distances to slow down.
The sectional area that gas passes through in blast pipe gently increases, and reduces gas flow rate gently, the setting of variable diameter porous plate
Keep front and back intake unanimously uniform, in the process, due to the reduction of speed, most of partial size is big, the big particle of density due to
The reason of inertia and gravity, directly settles and falls into ash bucket, and when dusty gas contacts dedusting filtering bag, speed is slowly uniform, and dustiness subtracts
It is few, the treatment effeciency of deduster is greatly improved, the service life of dedusting filtering bag is extended.
