Abstract
The utility model discloses a bag self-cleaning dust remover for ventilation and dust removal. The dust remover is composed of a cylinder body, a cleaning hole plate, a rib rack in a cloth bag, the cloth bag, a mechanism for positioning and loosening the cloth bag, a dust collecting box, an arched dust scraping plate, a main shaft, a rotatory blowing pipe, an anti-blocking air shutter, a gear speed reducer, a cleaning blower, etc. Dusty air enters the dust remover through a spiral air inlet, and the air is exhausted from the upper part of the cloth bag after dust filtration in the cloth bag. Dust deposited on the surface of the cloth bag is blown by a self-rotating blowing pipe of the cleaning blower, and dust deposited in the dust collecting box is discharged by the main shaft which drives the arched dust scraping plate from an outlet through the air shutter. The cleaning blower is controlled to start and stop by an automatic control system.
Description
The utility model belongs to dust removal by ventilation and Pneumatic Conveying Technology field, particularly is applicable to the Bag self-cleaning deduster that factory's trap dust such as feed processing, grain processing, cement and chemical industry purify air.Its international Patent classificating number is B01D.
Deduster should have the efficiency of dust collection height, be easy to characteristics such as dust discharge on performance.Before the utility model was made, as the sack cleaner of prior art, as the mechanical vibrator sack cleaner, though simple in structure, fitting operation was convenient, only is applicable to little dirt source point, and handling air quantity can not be too big, and efficiency of dust collection is low; Though blowback wind deduster can continue filter dirt in deashing, it is bigger to handle air quantity, weak point be structure plain heavy, appearance and size is high, installation and transportation are difficult, when cloth bag is changed in maintenance, the operator need enter in the deduster, working condition is abominable, drive apparatus is many, dust free-falling to cone time outlet easily stifled, and power consumption is big, the internal work situation is difficult for observing (Tan Tianhu: industrial ventilation dedusting technology, China Construction Industry Press, 1984; Su Ruwei: industrial ventilation and dustproof engineering science, publishing house of Beijing Economics College, nineteen ninety).
The utility model overcomes above-mentioned deficiency and a kind of efficiency of dust collection height of designing exactly, can clear up dust automatically, and is simple and reasonable for structure, can observe the internal work situation, is convenient to transport, fitting operation and Bag self-cleaning deduster easy to maintenance.
The purpose of this utility model can reach by following measure:
The deduster shell is a circular cylinder body, and cylindrical shell and frame merogenesis are made, and connect into integral body with flange then.Inlay three arc glass windows of being convenient to observe and be convenient for changing cloth bag around the cylindrical shell, cylindrical shell top connects the top cover case, and the top cover upper box part is installed the vertical type blower fan, and the following end device of the outlet of blower fan and main shaft ring set revolves blowpipe.Cylindrical shell top connects the spiral air inlet of arc spiral case.N in device is installed the interior muscle frame of cloth bag of cloth bag in the cylindrical shell, and the top of muscle frame is connected with the cleaning orifice plate with flange in the cloth bag, and cloth bag overlaps from bottom to top to flange, ties up with rope band.The bottom of cylindrical shell is provided with the location that cooperates the replacing cloth bag to use with muscle frame in the cloth bag frame casket that gets loose.The cylindrical shell lower bottom part is provided with flat disposal box.The center of cylindrical shell is provided with main shaft, and the two ends up and down of main shaft connect with bolt respectively goes up semiaxis and following semiaxis, and device is scraped hawk and dust-blocking cover at the disposal box place.
The exit of cylindrical shell bottom disposal box connects anti-blocking airlock, the bottom device gear-shift mechanism, and the impeller shaft device sprocket wheel of anti-blocking airlock by the chain drive gear-shift mechanism, rotates thereby drive main shaft.
Specifically, the utility model can also reach by following measure:
Make cylindrical shell with the metal material merogenesis, connect with steel flange between every joint, n the arc glass window of being convenient to observe and be convenient for changing cloth bag is set around the cylindrical shell, encapsulant all is housed around steel flange and the arc glass window.The top cover case that the upper top device of cylindrical shell connects with securing member, device cleaning blower fan on the plane of top cover case.Cylindrical shell top is fixed with the cleaning orifice plate, and the bottom is provided with cloth bag location release mechanism, and the cleaning orifice plate is corresponding with the hole of cloth bag location release mechanism.Mounting flange dish, sealing gasket and securing member constant cross-section are the trapezoidal interior muscle frame of 12 cloth bags below the cleaning orifice plate.Cloth bag by under be inserted in the muscle frame, suitable for readingly be banded on cleaning orifice plate bottom and the interior muscle frame flange connecting dish by rope band.The interior muscle frame lower end that cloth bag is housed puts the posting casket again, and an end of posting casket is connected with fixing ring stand with bearing pin, other end usefulness bolt and fixedly ring stand locate.When drawing back pin, the posting casket can be rotated down 90 °.
The center fixture main shaft of cylindrical shell, the two ends up and down of main shaft connect with bolt respectively goes up semiaxis and following semiaxis.The blowpipe that revolves at cylindrical shell top is connected the top that is fixed on semiaxis with the vertical axis cover, and the air inlet that revolves blowpipe is relative with the air-out vertical tube of blower fan, and the vertical air outlet of blower fan maintains static, and revolves blowpipe with main axis rotation.Be matched in clearance herein, revolve the hole of the gas outlet corresponding flat cleaning orifice plate of blowpipe, circular cleaning orifice plate is fixed on cylindrical shell top.Drive the arc dust scraping plate by main shaft, dust-blocking cover, revolve the blower rotary work.
