Abstract
The invention discloses a pulse bag type dust collector blow pipe and a manufacturing method thereof. The product comprises a pipe body, wherein a plurality of air outlet holes are arranged on one side of the pipe body; each air outlet hole is respectively connected with a short pipe; and the pipe body at the outer edge of the air outlet hole is in the shape of a chamfer angle. The structure is reasonable, and pulse blowing strength or range can be increased effectively. The test reveals that, with the adoption of the scheme, when the pulse blowing range is the same, the amount of compressed air can be saved by about 20% or the blowing strength can be improved in comparison with the prior art; when the consumption of the compressed air is the same, the range can be increased by about 30% in comparison with the prior art, so that the satisfied effect can be obtained for a filter bag higher than 6 meters.
Description
Technical field
The present invention relates to a kind of pulse bag type dust collector winding-up pipe and manufacturing approach thereof.
Background technology
Improving constantly of Along with people's living standard, more and more stronger to the protection of environment consciousness, therefore, the use of deduster becomes more extensive in commercial production, and the thing followed is, the performance requirement of deduster is improved constantly.
Pulse bag type dust collector is a kind of device of dry type Chalk-dust filtering.It is applicable to and captures tiny, dry, non-fiber dust.Be applicable to the smoke harnessing of industries such as metallurgy, pottery, chemical industry, grain processing, machine-building, mining industry.Small-sized deduster is applicable to that grinding operation, package handling, powder drop into environment such as operation, frosted operation, cutting operation, bore operation, cutting operation, stirring operation, comminution process simultaneously.Good deduster dust treatment effect can reach 99.9%.Along with the development of sack cleaner technology and the raising day by day of environmental requirement, can utilize sack cleaner to handle high temperature, high humidity, bonding, blast, abrasion flue gas at present, even filter the air that contains ultrafine dust.Sack cleaner at present can the flue gas of treatment temperature below 300 ℃, surpasses this temperature and then tackle flue gas and carry out pre-cooled processing, under special circumstances, can use the metallic fiber filtrate directly to handle 450～550 ℃ high-temperature flue gas.Handle the flue gas of high temperature kilns such as steam boiler, cement kiln, metallurgical furnace kiln, incinerator with sack cleaner, day by day general at home and abroad.The caking property dust hardens on the filter bag surface easily; Sack cleaner can be handled the caking property dust through suction-operated; Promptly in system pipeline, mix an amount of mushy powder, utilize powder to adsorb the caking property dust, carry out purified treatment by sack cleaner then.
Plurality of advantages such as pulse bag type dust collector is because of saving the energy, and at the bottom of the equipment operation management expense, efficiency of dust collection is high, save infrastructure investment, and volume and floor space are little at home and abroad develop rapidly.Its weak point is to have only injection hole on the conduit that passes through of Compressed Gas; Therefore the consumption of Compressed Gas is bigger than normal; At the bottom of the winding-up intensity, ash-removal effect is poor, and range (pulse jet gas gets into the effective impulse deashing distance in the filter bag) is short; Cause long filter bag bottom ash-removal effect very poor, even can not deashing.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, can effectively strengthen the pulse bag type dust collector winding-up pipe and the manufacturing approach thereof of pulse jet intensity or range.
Technical solution of the present invention is:
A kind of pulse bag type dust collector winding-up pipe comprises body, and it is characterized in that: body one side is provided with a plurality of ventholes, and each venthole is connected with a short tube respectively, and the body at venthole outer rim position is the chamfering form.
A kind of manufacturing approach of pulse bag type dust collector winding-up pipe is characterized in that: comprise the following steps:
(1) on body, opens aperture; And in body, place the hydraulic mandril device, and the hydraulic mandril device comprises hydraulic mandril, the hydraulic mandril end is connected with backstay; The diameter of backstay is smaller or equal to the diameter of said aperture, and the diameter of hydraulic mandril is greater than the diameter of said aperture;
(2) hydraulic mandril mechanism is stretched out, make backstay stretch into said aperture, and further make hydraulic mandril make aperture, hydraulic mandril mechanism withdraws from, aperture venthole, the body at venthole outer rim position is the chamfering form.
The present invention is rational in infrastructure, can effectively strengthen pulse jet intensity or range.Evidence, when the pulse jet range was identical, this programme was saved the compressed gas scale of construction about 20% or is improved winding-up intensity than prior art; When consuming identical air supply, can increase the range about 30% than prior art, thereby can obtain gratifying effect for the filter bag more than 6 meters.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of product of the present invention.
Fig. 2 is the partial enlarged drawing at the venthole position of Fig. 1.
Fig. 3, Fig. 4 are the venthole process drawings.
The specific embodiment
A kind of manufacturing approach of pulse bag type dust collector winding-up pipe comprises the following steps:
(1) on body 1, opens aperture 4; And in body, place the hydraulic mandril device, and the hydraulic mandril device comprises hydraulic mandril 2, the hydraulic mandril end is connected with backstay 3; The diameter of backstay is smaller or equal to the diameter of said aperture 4, and the diameter of hydraulic mandril is greater than the diameter of said aperture 4;
(2) hydraulic mandril mechanism is stretched out; Make backstay stretch into said aperture, and further make hydraulic mandril make aperture, hydraulic mandril mechanism withdraws from; Aperture venthole; The body at venthole outer rim position 5 is chamfering form (promptly at this position, towards the venthole direction, the attenuation gradually of the tube wall of body).
The pulse bag type dust collector winding-up pipe that makes comprises body 1, and body one side is provided with a plurality of ventholes, and each venthole is connected with a short tube 6 respectively, and the body at venthole outer rim position is the chamfering form.Also have pulse valve 7 among the figure, divide gas bag 8, cloth bag 9.
