Abstract
The present invention relates to an active dust suction type air return filter. A filter screen is fixed on a machine base or in a wall hole. After a blower is started for air draft, a speed reducer drives a hollow transmission shaft and a suction cleaner to rotate, the suction cleaner sucks and eliminates dust attached on the screen surface of the filter screen, and the dust flows into an air distributing box and a dust collecting device through the hollow transmission shaft and a dust pipe. The air return filter of the present invention has the advantages of thorough dust removal, no air leakage, high efficiency, little filtration resistance and 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 from gas or steam of being specifically designed to, particularly relate to a kind of active dusting back breeze filter of fibre-bearing dust.
Air-conditioning system is generally all utilized and is filled air-conditioned room air (being return air), returns air conditioning chamber, after mixing, through air-conditioner processing, sends into the place that needs air-conditioning with outdoor new wind.At present, the air-conditioning system of textile industry, for the return air that contains the dust such as fiber, must be filtered through one return air, just can send into air conditioning chamber, like this could be clean empty
Existing return air filter has a circular screen pack, screen pack motor and transmission mechanism drive, make it revolution, return air filter is contained in air conditioning chamber's porthole, owing to there being blower fan exhausting in air conditioning chamber, make screen pack both sides cause an air pressure difference, screen pack is negative pressure by air conditioning chamber's one side, opposite side is malleation, dust laden air (return air) in malleation side flows to screen pack, after strainer filtering, enter the air conditioning chamber of suction side, in return air, contained fiber dust is adsorbed on the screen pack of inlet side, on the filtration wire side of being close to inlet side, brush or scraper plate are housed, or in filtering net surface, be covered with disposal box, cause what is called " zone of silence ", in the time that screen pack turns round, the fiber dust that invests wire side nuzzles up brush or scraper plate and is scraped and brush down, or fall into the bottom of disposal box, can regularly manually remove,
Above-mentioned return air filter exists following shortcoming:
1. to make brush or scraper plate brush away the fiber dust that invests screen pack wire side, brush or scraper plate must press filter screen, and filter screen both sides air has certain pressure reduction, filter screen air side is low-pressure area, has the dust attracting on filter screen to flow to the active force of air side, through wiper and the extruding of overcompaction wire side brush or scraper plate, impel wire side dust to flow into air side through filter screen, enter in filtered air, increased thus the dustiness of filtered air, reduce attached dirt efficiency
2. brush or scraper plate must be close to filter screen wire side, could remove the dust that adheres to wire side.Therefore, the flatness mistake of requirement screen pack can not be too large, but the screen pack diameter of above-mentioned return air filter is generally 2～3 meters of left and right, foozle is inevitable very large, 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 filtration air quantity.
3. between disposal box and screen pack plane, namely on the rotating limit that enters of screen pack, must leave gap, could allow the fiber dust that wire side adheres to pass through, proceed in disposal box, allow brush or scraper plate wiper, owing to leaving this gap, the region that disposal box and filter screen wire side surround still has air to enter, be not real " zone of silence ", therefore, scrape from wire side the fiber dust brushing down and falling into the process of disposal box, still existed the attraction that air pressure difference causes to be again adsorbed onto wire side by wire side both sides, wire side dust can not be bought (or sell) on credit to the greatest extent, increase equally resistance, reduce filtration air quantity.
4. screen pack is contained in round frame, and circle frame is loaded in porthole, and circle frame is to shape with cold-working or hotwork, and without cutting, its diameter is large, and deviation from circular from is just large, and filter screen circularity diameter and coaxiality error are also large, the therefore larger gap of existence, one 10～15 millimeters the most.Like this, will seal gap as seal with rubber, but all large with surface jitter and flat deviation from circular from, rubber is not smooth yet, still has gap, leaks out, and dust laden air is flowed in the clean air having filtered, and has reduced efficiency of dust collection.
The object of this invention is to provide a kind of improved active dusting back breeze filter, the clear utmost point for prior art filters, 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 flow in clean air through mesh.
A kind of active dusting back breeze filter of the present invention comprises support, cylinder, filter screen, blower fan, motor and transmission mechanism, it also comprises the dust catcher with suction nozzle, the dust delivering tube being connected with above-mentioned transmission mechanism, matching air box and dust collect plant, described transmission mechanism comprises decelerator and hollow drive shaft, one end of hollow drive shaft is connected with the dust catcher that is arranged on filter screen upper rotary, size is about the cleaner suction nozzle of filter screen radius towards filter screen, filter screen is connected with cylinder by housing and is fixed on support or in porthole, matching air box with 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.
Compared with the return air filter of a kind of active dusting back breeze filter of the present invention and prior art, there is following advantages:
1. adopt revolution dust catcher to absorb the fiber dust of filter screen wire side, can not order about dust and flow in clean air and go through mesh, filter air quantity large, efficiency of dust collection is high.
2. adopt dust catcher dedusting, do not need " zone of silence ", can not occur to remove from wire side the fiber dust getting off and turn back to wire side and get on, everyly turn round inswept wire side through suction nozzle, the dust adhering to is all inhaled clear, and not only dedusting is effective, and reduced filtration resistance, increase filtration air quantity.
3. filter screen and cylinder entirety are fixing on the wall, filter screen transfixion, and there is not any gap around in filter screen, does not therefore leak out, and improved efficiency of dust collection.
4. filter screen maintains static, increase the rigidity of structure, adopt dust catcher dedusting, suction nozzle and the wire side larger gap that can be separated by, is generally 15～25 millimeters, and do not need to resemble prior art, brush or scraper plate is close to wire side, therefore, filter screen fabrication error can be larger, is convenient to manufacture, and saves man-hour.
Below in conjunction with accompanying drawing, the present invention is elaborated.
