Above-mentioned a kind of back-blowing bag-type dust collector, it is characterized in that: described compound air duct valve, its outside is valve shell, valve shell is divided into upper and lower two parts, top is perpendicular cone cylinder wide at the top and narrow at the bottom, perpendicular cone cylinder upper end open is import, and bottom is horizontal cylinder, and the lower end of perpendicular cone cylinder is connected with the sidewall of horizontal cylinder; Horizontal cylinder open end is outlet, the other end sealing of horizontal cylinder; Blowback air channel is through the sidewall of perpendicular cone cylinder, blowback air channel inner port is positioned at perpendicular cone cylinder and opening upwards, and blowback air channel inner port marginal position is lower than inlet edge, and it is outer and be horizontally disposed with that blowback air channel external port is positioned at perpendicular cone cylinder; In valve shell, be designed with vertical pull bar, the top of pull bar is through blowback air channel sidewall, and termination, top passes and is connected with back-blowing sealing plate from blowback air channel inner port, and back-blowing sealing plate carries out shutoff to blowback air channel inner port; Pull bar bottom is designed with exhaust outlet sealing plate, and exhaust outlet sealing plate carries out shutoff to perpendicular cone cylinder lower port; The lower end of pull bar is connected with the piston rod outer end of cylinder, and cylinder is fixed on the below of horizontal cylinder; Blowback air channel and cylinder are connected with valve shell is airtight; Multiple compound air duct valves carry out anti-blow cleaning dust successively by electric control system controls.
Operation principle
This device is under high negative pressure state, to carry out work, dusty gas is from air inlet suction, heavier dust directly falls into lower box, then dusty gas enters respectively each dirt pocket, entering successively air-purifying chamber, compound air duct valve in dirt pocket after filter bag filters, then come together in and blend air channel and through exhaust duct air draft.
In the time that needs are cleared up a certain dirt pocket, control compound air duct valve rod up, by back blowing machine, the filter bag of a certain dirt pocket is carried out to deashing, the dust clearing out falls into lower box.After dedusting, control compound air duct valve rod descending, return to dedusting state; Other dirt pocket according to this principle operates successively.
Particularly, advantage of the present invention is as follows:
1, applied widely, the dedusting practicality that adapts to all kinds of heavy dust occasions of this product.
2, this product ventilation effect is good, occupies little space, low cost of manufacture, operation be simple and easy.
3, this product adopts locellus high-efficient reverse blowing deashing, and without shutting down, deashing and deashing are thorough.
4, unique wind path design, adapts to heavy dust containing Effect of Pretreatment, and life of bag filter is long.
5, electric automatization degree is high, and operation facilitates simple and easy.
