Description

A kind of pocket type is received the powder device

Technical field:

The utility model belongs to the metallurgy industry environmental protection equipment, is specifically related to a kind ofly prevent that the ultra-fine grain in the iron-smelting blast furnace production process is discharged into airborne device.

Background technology:

The receipts powder device that iron work uses now is to be made of strumbox, sand removing device, filter bag in the strumbox is a reversal of the natural order of things inward flow filtration-type cloth bag, its physical dimension is big, and the cloth bag inside and outside differential pressure changes greatly, the cloth bag cracky, filter bag very easily stops up, poor filtration effect influences normal coal powder injection operation, and the dust of removing on the filter bag is blown and beaten by artificial entirely, intensity of workers is bigger, influences working efficiency.

Summary of the invention:

The utility model aims to provide a kind of dust that can remove automatically on the filter bag, and the volume that alleviates intensity of workers is little, ash-removal effect good, the pocket type of long service life is received the powder device.

The realization the technical solution of the utility model is: comprise strumbox, separator box, sand removing device, the strumbox internal fixing is installed filter bag, baffle plate is set in the separator box, separator box is clipped in the centre of two strumboxes, strumbox, separator box all are not provided with at the bottom of the case, sand removing device is installed in the bottom of strumbox and separator box, it is characterized in that installing on the separator box back-blowing device, and the filter bag in the strumbox is to be linked together by the sack that several cross sections assume diamond in shape.

Described back-blowing device is to be made of blowback bellows, gas blower, cylinder, and gas blower is fixedly mounted on a side of blowback bellows, and cylinder is fixedly mounted on the top of blowback bellows, and the blowback bellows are arranged on the top of separator box.

Principle of work of the present utility model is: the air of band dust enters space below the separator box baffle plate from inlet mouth, granule dust drops into the lower floor in the sand removing device, air admission is to strumbox, the filter bag handle enters into the airborne fine particles detention of strumbox on its bag wall, through the uncovered space that enter into separator box baffle plate more than of filtered air, discharge by venting port from filter bag.When removing the dust on the filter bag bag wall, close venting port, start gas blower simultaneously, promote cylinder piston and move up, back draught enters into strumbox through separator box, disposes the dust on the filter bag bag wall.

By test at Taiyuan Iron ﹠ Steel's iron work, the utility model low cost of manufacture, automatic ash removing is effective, dust stratification not on the filter bag, volume is little, occupies little space, and safeguards simple, reliable, long service life has alleviated staff's labour intensity, has improved working efficiency.
