Description
Technical field
The present invention relates to a kind ofly can effectively the dust that attaches in cartridge wall and the filter opening wall be removed regeneration fast, can realize again removing the special-purpose filter cylinder rotary blowing regeneration cleaning system of cleaner and the renovation process of the regeneration of air-flow, belong to dust separation device filter cylinder regenerative system and make the field.
Background technology
CN202478744U, title " filtering cylinder ash cleaning device ", comprise air inlet pipe, inside is provided with the ventilation cavity and is provided with the blowback assembly of venthole, all bodies are provided with the exhaust apparatus of a plurality of steam vents, fixture, air inlet pipe connects and internal communication with the blowback assembly, the blowback assembly connect with exhaust apparatus and the blowback component internal by venthole with the exhaust apparatus internal communication, fixture with the blowback assembly connect to support, fixing whole device.
CN201768459U, title " a kind of surface deashing device for cylindrical filtering element ", middle cavities the inside in cylindrical filter element arranges blowback air-flow cleaning plant, deashing shower nozzle and localized ejection go out the dust that the blowback air-flow blows the deposition of cylindrical filter element outside off, and the deashing shower nozzle of described blowback air-flow cleaning plant by drive unit relative rotation occurs with middle cavities and realizes 360 degree cleanings.
Weak point in the above-mentioned background technology: the one, can't effectively realize the regeneration of air-flow; The 2nd, regeneration effect is not good, still it is can't effectively remove to be attached to the dust that reaches on the cartridge wall on the filter opening wall, and this also is a for a long time insurmountable difficult problem of this area, causes regeneration effect poor, the regeneration filter cylinder uses makes the sharp increase of dust separation device energy consumption, and regeneration effect is poor, service life is short.
Summary of the invention
Purpose of design: avoid the weak point in the above-mentioned background technology, design and a kind ofly can effectively the dust that attaches in cartridge wall and the filter opening wall be removed regeneration fast, can realize again removing the special-purpose filter cylinder rotary blowing regeneration cleaning system of cleaner and the renovation process of the regeneration of air-flow.
Design: in order to realize above-mentioned purpose of design.1, the special-purpose filter cylinder rotary blowing regeneration of cleaner cleaning system is one of technical characterictic of the present invention by the design that filter cylinder rotary blowing reclaim equiment and gas purifying equipment consist of.The purpose of doing like this is: because filter cylinder rotary blowing reclaim equiment adopts high pressure blow smelting operation to combine with filter cylinder whirling vibration in structural design, it can make the dust that is attached to the dust on the filter cylinder face and is attached on the filter opening wall separate with wall rapidly by vibration, high pressure blow smelting operation, thereby reaches the purpose of rapid regeneration; The dust that gas purifying equipment produces in the time of then filter cylinder can being regenerated sucks in it, purifies, and makes pure air-flow after the purification again as the source of the gas of filter cylinder rotary blowing, thereby reaches the purpose of regeneration air stream, recycling, protection of the environment.2, the cone point of a plurality of cone posts in filter cylinder rotary blowing pipe support bottom is provided with the design of ball, is two of technical characterictic of the present invention.The purpose of doing like this is: because what form between the filter cylinder rotary blowing pipe support bottom cone post that be used for to support filter cylinder and the convex vibration plate face is to be concavo-convex whirling vibration to cooperate, the frequency of its vibration forces the cone post to produce and beats and drive the filter cylinder generation that is reproduced to be vibrated, the vibration of filter cylinder force be attached on the cartridge wall and filter opening in dust fast with in cartridge wall, filter opening wall separate, are shed to V font funnel after enter material-storing box, thereby solve the deficiency that the background technology of knowing clearly exists.
Technical scheme 1: the special-purpose filter cylinder rotary blowing regeneration of a kind of cleaner cleaning system is made of filter cylinder rotary blowing reclaim equiment and gas purifying equipment; Cabinet in the described filter cylinder rotary blowing reclaim equiment is provided with between case lid and case lid both sides and the casing and is connected by the gas bar, the bottom of cabinet is provided with material-storing box, be equipped with V font funnel on the material-storing box and V font funnel is built-in with filter cylinder rotary blowing pipe support, the cone point that filter cylinder rotary blowing pipe support bottom is provided with a plurality of cone posts and cone post is with the convex vibration plate that is positioned at V font funnel and is slidingly matched, filter cylinder rotary blowing pipe support bottom is communicated with tracheae one end by the gas transmission rotary union assembly, tracheae other end booster pump gas outlet is communicated with, the booster pump air inlet is communicated with the gas outlet that purifies air of gas purifying equipment, and cabinet top has dust exhausting hole and dust exhausting hole is communicated with the import of gas purifying equipment Air by metal hose.
Technical scheme 2: the renovation process of the special-purpose filter cylinder rotary blowing regeneration of a kind of cleaner cleaning system, put into saturated filter cylinder in the cabinet and be enclosed within on the filter cylinder rotary blowing pipe support, by gas bar closed pneumatic case lid; After starting gas purifying equipment, the gas purifying equipment clean gas that the gas outlet discharges that purifies air is supplied with booster pump by appendix, air-flow after the supercharging is through tracheae, in each air jet pipe after the gas transmission rotary union assembly distributes high pressure draught in the filter cylinder rotary blowing pipe support and by the nozzle on the air jet pipe high pressure draught is ejected on the wall of filter cylinder by certain angle and promotes the filter cylinder rotation, because being concavo-convex rotation for the filter cylinder rotary blowing pipe support bottom cone post that supports filter cylinder with convex vibration plate face cooperates, the convex vibration plate of male and fomale(M﹠F) forces the cone post to produce and beats and drive the filter cylinder generation that is reproduced and vibrates, thereby force the dust that is attached on the cartridge wall to separate with cartridge wall fast, enter material-storing box after being shed in the V font funnel, and be positioned at cabinet top dust exhausting hole under the effect of gas purifying equipment, by metal hose dusty gas in the cabinet being sucked gas purifying equipment purifies, clean gas after the purification is then again by the gas outlet that purifies air, appendix is supplied with booster pump, air-flow after the supercharging is through the filter cylinder rotary blowing pipe support of tracheae to the filter cylinder rotary blowing reclaim equiment, so circulation is until filter cylinder regeneration is finished.
The present invention compares with background technology, and the one, effectively realize the regeneration of air-flow; The 2nd, regeneration effect is good, still it is can effectively remove to be attached to the dust that reaches on the cartridge wall on the filter opening wall, has solved a for a long time insurmountable difficult problem of this area, favorable regeneration effect, solve the regeneration filter cylinder and used the defective of making the dust separation device energy consumption, long service life.
