Description

All-functional electrostatic efficient curtain-type dedusting machine

The present invention a kind ofly is used to filter the gas that contains fiber impurity, suspension, dust and efficiently captures dust, extremely short fiber so that the gas dustiness reaches and conforms with the environmental sanitation requirement with reciprocal curtain filter screen or fixing circle shape filter screen defibre impurity, suspension with the reciprocal curtain of static, has the all-functional electrostatic efficient curtain-type dedusting machine of electromechanical integration function.

At present the home and abroad is used to weave, the dirt catcher of tobacco and other industry filtering dust-contained airflow mainly contains and have preseparator and the outer widely different commentaries on classics dirt catcher (being Luo Washi and domestic imitative Luo Washi) chewed, XLZ combined type dirt catcher, internal-suction type dirt catcher, flat dirt catcher, the honeycomb fashion dedusting unit etc. inhaled.Though XLZ combined type dirt catcher has advantages such as structure is simple, floor space is little, but in the dust pelletizing system design, main air blower must be contained in before the dirt catcher, makes impeller easily twine flower, operation under positive pressure environmental sanitation condition is poor, the system filtration load is big, and ventilation is little, and resistance is big, cross area and the floor space multiple proportions is little, can not prevent fires, inconvenient maintenance, domestic employing is fewer and feweri; Internal-suction type, outer suction formula rotary filter have all that floor space is big, filter area and the floor space multiple proportions is little, ventilation is little, resistance is also bigger, the rotary filter that has preseparator can not be prevented fires, fire alarm often appears in the production run, there are many problems and defect in actual the use, have been tending towards the gesture of eliminating at home, outward; Flat dirt catcher filter area is big, floor space is more preceding smaller, has the one-level fire protecting performance, filter area and floor space multiple proportions are big, by the PC programme-control dust on the filtrate face in each groove is carried out back and forth back and forth wheel suction and is provided with special gearing doing regularly to move back and forth up and down, like this, the electrical equipment complexity, the machine driving operating mode is abominable, be difficult for maintenance, the dust suction plastic tape is short easily broken service life, and the sealing difficulty, easily leaks out, the secondary filtrate is not easy to clean clean, maintenance workload is bigger, and particularly electrical equipment and machine components are through operation back reliability decrease about half a year, easy break-down.External and the domestic honeycomb fashion dedusting unit that occurred in recent years, owing to still have and the similar reciprocating machine of flat filter dirt machine, Electrified Transmission mechanism, and upper and lower filtrate tube is because sweep-up pipe pressure reduction is former thereby dust can not be cleaned consistent clean, the filtrate clean cycle time is still at 6-12 minute, so the weakness that still can not avoid dull and stereotyped dirt catcher to exist, the function that does not more have electrostatic precipitation, thereby to micronic dust, the removing of sub-micro dirt does not reach customer requirements, can't resolve ubiquitous " coal-dust stained yarn " problem.

It is worthy of note above two kinds of most representative types especially, its cascade filtration filtrate all can not clean continuously, and it is little less than the ultrafine dust effect of secondary filtrate cloth micro-pore for removing, its efficiency of dust collection can not satisfy the needs of development, also big shortening can't be arranged again and further improve the filtrate cleaning time.Thereby ventilation and appearance and size are subjected to inevitable restriction.Owing to mainly be the product that the external technology of digestion is made, so backward relatively.Have the textile dust extraction device of electrostatic precipitator, abroad only studying, do not see to come into the market to use domestic blank out especially.

The objective of the invention is: adopt ring-type filtrate cloth that ring-type filter screen or circle shape filter screen and chemical fibre make respectively as the filtrate of one-level filter and cascade filtration device, utilize the rotation of live-roller and make them turn round and do flexible moving (conversion rate as required) along the live-roller surface, to increase the media filtration area significantly and to dwindle dust removal machine volume and floor space, one, secondary ring-type filter screen, several fiber suction pipe or sweep-up pipes by the blower fan suction are equipped with in the front of cloth, reverse side then has several carrying rollers and sends into fine pipe of blowing of certain pressure gas or dust blowing tube by hair-dryer, and the suction pipe of drawing short fiber also is equipped with in one-level ring-type filter screen inboard (the inside); In the secondary filter chamber, the static generation roller of positive several high speeds made of plastic rotations in addition of secondary ring-type filtrate cloth and ring-type filtrate cloth rub and make the surface generation of ring-type filtrate cloth can attract the electrostatic charge of ultrafine dust and extremely short fiber, and the frictional drive of the little carrying roller of several plastics that ring-type filtrate cloth and reverse side are installed has also been strengthened the continuous generation of electrostatic charge and gathered.Electrical control cubicles can make amount of electrostatic charge remain at safety and effectively remove the level of fine dust.Like this, enter the one-level filter chamber and constantly accumulate in fiber impurity in the fine dust gas on the ring-type filter screen, suspension and on a small quantity with the dust of fiber wrapped folder very fast by pressure-vaccum enter horizontal horizontal installation and and special fan be contained in the high-efficiency fiber separator on machine top separated from the gas and by outside the continuous extruder automatically, and enter fine dusts in the gas of secondary filter chamber and extremely short fiber by ring-type filter screen hole owing to pressure reduction reason and electrostatic attraction, the very fast micro-pore that can not arrive and pass through the positive inboard of ring-type filtrate cloth attached to the surface of the moving ring-type filtrate cloth that has a large amount of electrostatic charges of not stopping transport, owing to blow, the acting in conjunction of sweep-up pipe enters mixed bellows and is constantly scraped bottom fine dust compactor attached to the screen tube surface by continuous rotating spiral cleaning foil, by outside the continuously automatic extruder, concentrate discharging simultaneously.The rotating band kinetodesma suction pipe that another kind of one-level filter (Type B) then utilizes live-roller and dust blowing tube in the positive and negative of circle shape filter screen relative do gyration synchronously so that attached to the fiber impurity in circle shape filter screen front, suspension and blown very soon with the dust of fiber wrapped folder on a small quantity, horizontal horizontal installation is gone in inspiration and and special fan be contained in the high-efficiency fiber separator on machine top separated from the gas and by outside the continuous extruder automatically, its cascade filtration apparatus structure is the same with aforementioned (A type).Like this, the ring-type filtrate cloth of the ring-type filter screen of one-level filter (A type) and circle shape filter screen (Type B) and cascade filtration device can both keep continuous and stable self-cleaning function and not only keep bigger ventilation wind speed but also the good function that can effectively stop fine dusts and extremely short fiber to pass through, do not have flat, the such structure of honeycomb fashion dust removal machine is comparatively complicated, be prone to the reciprocal drive mechanism of advance and retreat of fault, filter floor space ratio and filtrate unit are ventilation than all model dedusters are all much bigger now, owing to have the function (this all is the function that at present domestic and international textile dust extraction device fails to possess) of electrostatic precipitation simultaneously, reached and both improved filter efficiency and ventilation, also improved simultaneously the purpose of design of efficiency of dust collection, it also possesses fire-proof function, can be under negative pressure or malleation operating mode operate as normal, full machine compact conformation, check, easy to maintenance, electric drive control system is simple, safe and reliable, with this end in view and the invention a kind of novel all-functional electrostatic efficient curtain-type dedusting machine.
