Abstract
The present invention relates to a kind of active dusting back breeze filter, filter screen is fixed on the support or in the porthole, after the fan starting exhausting, decelerator drives hollow drive shaft and dust catcher revolution, dust catcher will invest the dust of filter screen wire side and absorb, and dust flows into matching air box and dust collect plant by hollow drive shaft and dust delivering tube.Return air filter dedusting of the present invention is not leaked out to the greatest extent, the efficient height, and filtration resistance is little, convenient processing and manufacture.
Description
The present invention relates to separator, relate to a kind of improved filter and filter method that dispersed granules is separated that be specifically designed to from gas or steam, particularly relate to a kind of active dusting back breeze filter of fibre-bearing dust.
Air-conditioning system is generally all utilized the room air (being return air) that air-conditioning is housed, and returns the air conditioning chamber, after the chamber is located new wind and mixed, handles through air-conditioner, sends into the place that needs air-conditioning.At present, the air-conditioning system of textile industry must be filtered through a logical return air for the return air that contains dust such as fiber, just can send into the air conditioning chamber, like this ability pure air.
Existing return air filter has a circular screen pack, and screen pack is driven by motor and transmission mechanism, makes it revolution.Return air filter is contained in air conditioning chamber's porthole, owing in the air conditioning chamber blower fan exhausting is arranged, make the screen pack both sides cause an air pressure difference, screen pack is a negative pressure by air conditioning chamber's one side, opposite side is a malleation, and the dust laden air (return air) that is in the malleation side flows to screen pack, behind strainer filtering, enter the air conditioning chamber of suction side, fiber dust contained in the return air is adsorbed on the screen pack of inlet side.Brush or scraper plate are housed being close on the filtration wire side of inlet side, brush or scraper plate are covered with disposal box, cause what is called " zone of silence ".When screen pack turned round, the fiber dust that invests wire side nuzzled up brush or scraper plate and is scraped and brush down, and falls into the bottom of disposal box, can regularly manually remove.
Above-mentioned return air filter exists following shortcoming:
1, the fiber dust that brush or scraper plate are brushed away invest the screen pack wire side, brush or scraper plate must press filter screen.And filter screen both sides air has certain pressure reduction, the filter screen air side is a low-pressure area, there is the dust that attracts on the filter screen to flow to the active force of air side, wiper and extruding through overcompaction wire side brush or scraper plate, impel wire side dust to pass filter screen and flow into the air side, enter in the filtered air, increased the dustiness of filtered air thus, reduced efficiency of dust collection.
2, brush or scraper plate must be close to the filter screen wire side, could remove the dust that adheres to wire side.Therefore, require the flatness error of screen pack can not be too big.But the screen pack diameter of above-mentioned return air filter is generally about 2～3 meters, and foozle is inevitable very big, can not accomplish that brush or scraper plate and wire side be close to everywhere.So just make wire side dust not divisible, increased resistance, reduced the filtration air quantity.
3, between disposal box and screen pack plane, just, must leave the gap on the rotating limit that enters of screen pack, the fiber dust that could allow wire side adhere to passes through, and changes in the disposal box, allows brush or scraper plate wiper.Owing to leave this gap, disposal box and filter screen wire side area surrounded still have air to enter, and are not real " zone of silence ".Therefore, scrape the fiber dust that brushes down from wire side and falling into the process of disposal box, still the attraction that is existed air pressure difference to cause by the wire side both sides is adsorbed onto wire side again, makes wire side dust not divisible, has increased resistance equally, has reduced the filtration air quantity.
4, screen pack is contained in the round frame, and the circle frame is loaded in the porthole, and the circle frame is to shape with cold-working or hotwork, and without cutting, its diameter is big, and deviation from circular from is just big, and filter screen circularity diameter and coaxiality error are also big, therefore has big gap, is generally 10～15 millimeters.Like this, will seal the gap as seal with rubber, but wire side is beated and flatness error is all big, rubber is not smooth yet, still has the gap, promptly leaks out, and dust laden air is flowed in the clean air that has filtered, has reduced efficiency of dust collection.
The purpose of this invention is to provide a kind of improved active dusting back breeze filter, passiveness at prior art is filtered, and carries out positive dust-absorbing filtering, makes it thoroughly to remove screen pack wire side dust, can not leak out, dust also can not pass mesh and flow in the clean air.
A kind of active dusting back breeze filter of the present invention comprises support, cylinder, filter screen, blower fan, motor and transmission mechanism, and it also comprises the dust catcher that has suction nozzle, dust delivering tube, matching air box and the dust collect plant that is connected with above-mentioned transmission mechanism; Described transmission mechanism comprises decelerator and hollow drive shaft, one end of hollow drive shaft be arranged on filter screen on rotating dust catcher be connected, size is about the cleaner suction nozzle of filter screen radius towards filter screen, filter screen is connected with cylinder and is fixed on the support or in the porthole, the matching air box that has dust is connected with dust collect plant, wherein dust from dust catcher flow into hollow drive shaft and by dust delivering tube to matching air box.
A kind of active dusting back breeze filter of the present invention is compared with the return air filter of prior art, has following advantage:
1, adopt the revolution dust catcher to absorb the fiber dust of filter screen wire side, can not order about dust and pass mesh and flow in the clean air and go, it is big to filter air quantity, the efficiency of dust collection height.
2, adopt the dust catcher dedusting, do not need " zone of silence ", can not take place to remove the fiber dust that gets off and turn back to wire side and get on from wire side.Every through the inswept wire side of suction nozzle revolution, adhered dust is all inhaled clear, and not only dedusting is effective, and has reduced filtration resistance, has increased the filtration air quantity.
3, filter screen and cylinder overall fixed on the wall, there is not any gap around the filter screen in the filter screen transfixion, does not therefore leak out, and has improved efficiency of dust collection.
4, filter screen maintains static, and has increased the rigidity of structure.Adopt the dust catcher dedusting, suction nozzle and the wire side bigger gap that can be separated by is generally 15～25 millimeters, brush or scraper plate is not close to wire side and need not resemble the prior art.Therefore, the filter screen fabrication error can be big, is convenient to make, and saves man-hour.
Below in conjunction with accompanying drawing the present invention is elaborated.
