Abstract
The invention discloses a bag filter. A dust removal box is arranged on a collection box. An air inlet is formed in one side wall of the dust removal box, and an air outlet is formed in the other side wall of the dust removal box. A plurality of independent box units are arranged in the dust removal box. A plurality of rows of filter bags are arranged in each independent box unit. Corresponding flues are arranged on the upper portions of the independent box units. Off-line valves are arranged on the flues respectively. A blowing system is arranged above each row of filter bags. Each blowing system comprises a blowing pipe and a plurality of blowing openings formed in the side wall of the blowing pipe. A pulse valve is arranged at one end of each blowing pipe, and the two ends of each blowing pipe are movably connected to the corresponding independent box unit. Each blowing system further comprises a swing driver. The output ends of the swing drivers are connected with the blowing pipes. The bag filter can swing to remove dust.
Description
Technical field
The present invention relates to powder collection device field, particularly relate to a kind of bag hose.
Background technology
Fume gases is filtered by sack cleaner, forms dust just dirt on filter bag surface, and in dust removal process afterwards, dust just dirt just becomes the main filtration layer of filter bag.Along with the corresponding increase of dust resistance, the pressure reduction when filter bag both sides is increased to a timing, the fine dust be attached on filter bag layer can be squeezed away, efficiency of dust collection is obviously declined.Therefore, when dust remover resistance is wanting timely deashing after certain value.
Publication number be the bag hose of CN204275687U for Chalk-dust filtering, when needing deashing, then the Off-line valve on bag hose is closed, air-flow in bag hose casing is not circulated, then pulse valve is opened, carry out deashing to bag hose box house, entered rapidly in bag hose casing produce gas expansion by compressed air, filter bag shake reaches the object of deashing.Although existing bag hose casing correspondence is provided with multiple pulse valve of jetting to filter bag, but due to higher from pulse valve blowing gas pressure out, each pulse valve forms fixed-point type ground and jets to filter bag, most dust can be cleaned out like this, but owing to there is spacing between adjacent two pulse valves, therefore, filter bag still has interior part cannot obtain winding-up active force, causes ash-removal effect undesirable.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of can realization and swings the bag hose carrying out deashing.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of bag hose, comprise dust-removing box and collection tank, described dust-removing box is arranged in collection tank, described dust-removing box one sidewall is provided with air inlet, another sidewall is provided with air outlet, multiple independent case body unit is set in described dust-removing box, arrange in each independent case body unit and arrange filter bag more, described independent case body unit top arranges corresponding flue, described flue is equipped with Off-line valve, the top of often arranging filter bag all arranges an injection system, described injection system comprises injection tube and is arranged on the several winding-up mouths on injection tube sidewall, one end of described injection tube is provided with pulse valve, the two ends of described injection tube are movably connected on independent case body unit, also comprise a swinging driver, the output of this swinging driver is connected with injection tube.
Preferably, the winding-up mouth place of described injection tube is also provided with appendix, and the sectional area of the gas outlet of this appendix is greater than the sectional area of air inlet.
Preferably, described swinging driver comprises motor, and the output that this motor is fixed is connected with injection tube.
Preferably, described swinging driver comprises motor, bearing and decelerator, and described bearing is fixed on independent case body unit, and motor is fixed on bearing, and the output of motor is connected with the input of decelerator, and the output of decelerator is connected with injection tube.
Preferably, described decelerator is a pair sector gear.
Have employed such scheme, after compressed air enters into appendix, gas outlet due to appendix is that flat has little time to discharge, compressed air is squeezed at the middle part of appendix, be stressed to obtain and improve, on the other hand, the sectional area of the gas outlet of appendix is greater than the sectional area of air inlet, the gas outlet of adjacent two appendixs can be made adjacent, the blind area of giving vent to anger between two gas outlets is made to reduce widely like this, increase purging area, the gas exported from appendix is blown into filter bag, motor carries out the work rotated and reverse, thus power is delivered to injection tube by a pair sector gear, injection tube is produced swing, thus the gas be blown in filter bag is purged back and forth to filter bag.Therefore, after the present invention adopts the Purge methods of pendulum-type, filter bag is formed without dead angle cleaning, improves cleaning effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is the schematic diagram that swinging driver of the present invention is connected with injection tube;
In accompanying drawing, 1 is dust-removing box, and 2 is collection tank, and 3 is air inlet, and 4 is air outlet, and 5 is independent case body unit, and 6 is Off-line valve, and 7 is injection system, and 8 is injection tube, and 9 is appendix, and 10 is pulse valve, and 11 is motor, and 12 is bearing, and 13 is decelerator.
Detailed description of the invention
A kind of bag hose, comprise dust-removing box 1 and collection tank 2, described dust-removing box 1 is arranged in collection tank 2, described dust-removing box 1 one sidewall is provided with air inlet 3, another sidewall is provided with air outlet 4, in described dust-removing box 1, multiple independent case body unit 5 is set, arrange in each independent case body unit 5 and arrange filter bag more, described independent case body unit 5 top arranges corresponding flue, described flue is equipped with Off-line valve 6, the top of often arranging filter bag all arranges an injection system 7, described injection system 7 comprises injection tube 8 and is arranged on the several winding-up mouths on injection tube 8 sidewall, the winding-up mouth place of described injection tube is also provided with appendix 9, the sectional area of the gas outlet of this appendix 9 is greater than the sectional area of air inlet, preferably, the escape pipe of appendix 9 is set to taper, and gas outlet is flat, to improve the pressure of giving vent to anger.One end of described injection tube 8 is provided with pulse valve 10.The two ends of described injection tube 8 are movably connected on independent case body unit 5, and also comprise a swinging driver, the output of this swinging driver is connected with injection tube.Preferably, described swinging driver comprises motor 11, bearing 12 and decelerator 13, and described bearing 12 is fixed on independent case body unit, and motor 11 is fixed on bearing 12, the output of motor 11 is connected with the input of decelerator 13, and the output of decelerator 13 is connected with injection tube 8.Preferably, described decelerator 13 is a pair sector gear.One of them sector gear be connected on the output shaft of motor 11, another sector gear is connected in injection tube 8, and two sector gears engage each other.
