Description
Technical field
The invention belongs to powder collection device field, specifically a kind of adverse current pulse backblowing bag for collecting white carbon black
The combination blowing device of filter.
Background technology
The capital equipment that bag hose is that white carbon black is collected is collected, its effect is the powder charcoal by being conveyed with air-flow
Black collection, separation, being designed as using some of equipment standard ready for next step operation that be transported to white carbon black holding vessel
Bar filter bag is collected, and is conveyed with special equipment, but in actual production process, special due to white carbon black physical characteristics itself, typically
Equipment collect, conveying black carbon undesirable, easily cause buildup damage equipment, especially piled up in filter bag outer surface in white carbon black
Many, the blast of equipment when causing that in casing, pressure is excessive, is easily caused during over loading production, so as to reduce production efficiency, is wasted
Resource.
In the injection system of Publication No. CN202191804U, change of the Venturi tube to gas pressure is applied, makes arteries and veins
The filter bag shake that compressed air causes bag filter part is rushed, and white carbon black is shaken off.However, the compressed air from discharge pipe output can only
The dust of a part is cleaned out, its reason is, discharge pipe is fixed on casing, discharge pipe cannot action, that is to say, that go out
The trachea of airduct output is the injection for carrying out fixed-point type to filter bag, and it is larger that such processing mode obtains can only filter bag local
Shake, the amount of jitter that remaining position obtains is less, causes the cleaning effect of white carbon black unobvious.
Publication number CN105268258A discloses a kind of swing blowing device of bag hose, and this device makes to be arranged on filter bag
The appendix of top produces swing, so that the gas being blown in filter bag is purged back and forth to filter bag.Therefore, the present invention is adopted
After the Purge methods of pendulum-type, no dead angle cleaning is formed to filter bag, improves cleaning effect.However, as blowing device is arranged
In the top of filter pocket mouths, during injection, the gas major part of injection acts on the position near bag mouth, and gas flow to filter
Under the pressure of the middle and lower part of bag subtracts, therefore, cause the substantial cleaning effect in middle and lower part of filter bag poor.
Content of the invention
The purpose of the present invention is to propose to a kind of combination blowing device of the good reverse-flow pulse reverse-blow bag filter of cleaning effect.
The technical scheme for realizing the object of the invention is as follows：
The combination blowing device of reverse-flow pulse reverse-blow bag filter, including being installed on the casing of reverse-flow pulse reverse-blow bag filter
Compressed gas allotter, pulse valve, discharge pipe, discharge pipe with casing bag filter part be connected, on discharge pipe by rotation
Adaptor is connected with appendix, and appendix is connected with compressed gas allotter by pulse valve, is connected with the tube wall of discharge pipe
Multiple the first injection tubes that filter bag inside is blown, the side wall of the casing of the bag hose is provided with first support, case
The opposite side wall of body is provided with second support, and the two ends of the discharge pipe are respectively supported in first support and second support, institute
State first support and swinging driver is provided with, the swinging driver is connected with discharge pipe, the side wall of the casing is provided with use
In the second injection system that filter bag outer wall is blown.
Second injection system includes the second appendix and the second injection tube, several on the second gas transmission tube side wall
Second injection mouth, one end of the second injection tube is connected with the described second injection mouth, the axial direction of the second injection tube and the axial direction of casing
Between formed angle.
Second appendix is looped around around casing, and the side wall of the casing is provided with hole, the second injection tube
The other end is entered in casing through after the hole on wall box.
Second injection system is corresponding to the middle and lower part of filter bag.
Advantages of the present invention：Filter bag is blown into from the gas of discharge pipe output through the first injection tube, motor carries out rotating forward and anti-
The work for turning, so as to power is delivered to discharge pipe by drive mechanism, makes discharge pipe produce swing, so that being blown into filter bag
In gas filter bag is purged back and forth.The present invention is blown to the outer wall of filter bag also by the second injection system, filter bag
In the case that two sides all obtains injection, shake can filter bag, under shake active force, it is easier to make the dust stratification on filter bag
Drop, therefore, the present invention has more preferable cleaning effect to filter bag.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the top view of the second injection system in the present invention.
Specific embodiment
As depicted in figs. 1 and 2, the combination blowing device of the reverse-flow pulse reverse-blow bag filter of the present invention, inverse including being installed on
Compressed gas allotter 1, pulse valve 2 on the casing of stream pulse back-flushing bag filter, discharge pipe 3, in discharge pipe 3 and casing 4
Bag filter part is connected, and is connected with appendix 5 by swivel joint on discharge pipe 3, and appendix 5 is by pulse valve 2 and compressed gas
Body allotter 1 connects, and (in figure is not to be connected with multiple the first injection tubes that filter bag inside is blown on the tube wall of discharge pipe 3
Illustrate), the side wall of the casing 4 of the bag hose is provided with first support 6, and the opposite side wall of casing 4 is provided with second support
7, the two ends of the discharge pipe 5 are respectively supported in first support 6 and second support 7, and the first support 6 is provided with swing and drives
