Summary of the invention

Purpose of design: avoid the weak point in the background technology, design and a kind ofly both had winding-up, have the special-purpose pulse recoil deashing device of air cleaning facility and the ash removal method of dedusting and purifying air function again from the deashing function.

Design: in order to realize above-mentioned purpose of design.1, adopting the design of electromagnetic impulse valve control high pressure draught, is one of technical characterictic of the present invention.The purpose of doing like this is: it can make high pressure draught be the pulse type air feed; Thereby make the air-casing formula piston that constitutes by air-casing and piston wireway demonstrate high pressure, low-pressure state; The state of this high pressure, low pressure can piston motion form and move up and down, and drive the winding-up swivel mount through piston and move up and down.2, the design of air-casing formula piston is two of a technical characterictic of the present invention.The purpose of doing like this is: because the stopper rod of piston is steel pipe and is communicated with winding-up swivel mount air admission hole; Have air admission hole around the stopper ring of piston; Have pore on the piston rod on piston stopper ring top; Therefore when air pulse was got in the air cavity that is made up of piston stopper ring top and air-casing by the pore on the piston rod, its air pulse forced piston to be motion up and down, covers down motion thereby drive off-line ash-clearing.

Technical scheme 1: the special-purpose pulse recoil of air cleaning facility deashing device; It comprises the air cleaning cleaner, is provided with the jetting deashing system in the said cleaner, the triangle locating rack in the jetting deashing system be fixed on orifice plate the hole around; Off-line ash-clearing covers on the hole of orifice plate and is positioned at the triangle locating rack; The air-casing upper end is connected with triangle locating rack upper head plate, and piston is positioned at air-casing and the air-casing inwall moves up and down in the effect lower edge of compressed gas, and its piston rod upper end is passed air-casing and is spacing with stop nut and is slidingly matched; Stop nut is communicated with gas bag through wireway and impulse electromagnetic valve; Gas bag is positioned on the plate of orifice plate, and the lower end of piston rod is communicated with the winding-up swivel mount, and the winding-up swivel mount is positioned at filter cylinder and the swivel mount lower end of jetting holds out against handwheel and is rotating.

Technical scheme 2: the special-purpose pulse recoil of air cleaning facility deashing device from ash removal method; It comprises the air cleaning cleaner; When it comprises that filter cylinder in the air cleaning cleaner needs deashing regeneration; The band pressurized air source is given the gas bag air feed, opens impulse electromagnetic valve, after air pulse with pressure gets into piston through wireway; The piston of leading up to gets into the winding-up swivel mount, the pore on the piston rod on piston stopper ring top of leading up to gets in the air cavity that is made up of piston stopper ring top and air-casing and force piston to move up and down according to air pulse; Piston drives off-line ash-clearing and covers down when moving, and its winding-up swivel mount rotates in the effect bottom of air-flow, the limit deashing, thereby reaches the purpose of filter cylinder regeneration.

The present invention compares with background technology, and the one, both realized the purpose of air-flow regeneration filter cylinder having the little characteristics of noise again; The 2nd, structural design is novel, simple, reliable, practical.
