Abstract
The utility model relates to an air filter, in particular to an air filter which is applied in an inlet of a large scale air compressor and has the self-cleaning function. The air filter mainly comprises a shell, a control system and a filtration system which is arranged in the shell. The air filter is characterized in that the filtration system comprises a primary filtering device and a secondary filtering device which are composed of a plurality of parallel horizontal filter cartridges, wherein each horizontal filter cartridge is composed of a direct filter cartridge and an enlarging taper filter cartridge which are connected into a whole, a back-blowing self-cleaning device which is composed of an air storage pipe, a blowing valve, a blowing pipe and a tapping pipe is arranged in the shell, a nozzle which is corresponding to an air outlet end of each horizontal filter cartridge is arranged on the blowing pipe, and the utility model has the advantages that the filtering efficiency is high, the service life is long, the whole structure is compact, the occupied area is small, and the like.
Description
One, technical field
The utility model relates to a kind of air cleaner, and especially a kind of large-scale air compressor machine air cleaner inlet, that have self-cleaning function that is applied to belongs to the air cleaner technical field.
Two, background technology
Be subjected to the influence of dust for fear of large-scale air compressor machine inside, people are often installed dust removal filter additional at the air compressor machine inlet, and dust removal filter generally is to have the filter of self-cleaning system and be not with self-cleaning filter; Though the former can reach than higher degree on filter efficiency, exist filter to change frequently, need stop when changing filter shortcomings such as compressor operation; Often there is inefficient problem in the latter, though the filter efficiency of patent ZL2006200702817.2 increases, cartridge filter is the monotubular structure, and mounting means is vertical, and floor space is big.
Three, summary of the invention
The purpose of this utility model is intended at above-mentioned deficiency, and a kind of have self-cleaning function, compact conformation, long service life, efficient self-cleaning air cleaner that efficient is high are provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of efficient self-cleaning air cleaner, mainly comprise housing, control system and place the interior filtration system of housing, its special character is, filtration system comprises by several and arranged side by side is installed on one-level filter and the cascade filtration device that the horizontal cartridge filter on the retainer constitutes, and each horizontal cartridge filter all is the double-cylinder type structure that the enlarging awl filter cylinder by the straight filter cylinder of air intake and outlet air end is connected as a single entity and forms; In housing, be provided with the blowback self-cleaning device of mainly forming by cylinder, winding-up valve, winding-up pipe and pressure pipe, the winding-up pipe is connected with cylinder by the winding-up valve, the winding-up pipe is provided with and the corresponding nozzle of the outlet air end of each horizontal cartridge filter, and the winding-up valve is controlled by the magnetic valve group.
The good effect that compared with the prior art the utility model has is, because filtration fraction adopts cascade filtration, and the one-level filter has self-cleaning function, the filter efficiency height, air cleaning is more thorough, long service life, and its unique bedroom is arranged and is made filtration device structure compactness more, floor space is little, is easy for installation and maintenance.
Four, description of drawings
Fig. 1 is a plan structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of horizontal cartridge filter.
Five, the specific embodiment
For better understanding the utility model, it is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, efficient self-cleaning air cleaner described in the utility model mainly is by housing 12, control system 3 and places filtration system and blowback self-cleaning device in the housing to constitute, its filtration system comprises one-level filter and the cascade filtration device 5 that is made of several horizontal cartridge filters 17 arranged side by side, each horizontal cartridge filter 17 all is installed on the retainer 15, and all be to bore the double-cylinder type structure that filter cylinder 11 is connected as a single entity and forms by the straight filter cylinder 1 of air intake and the enlarging of outlet air end, between straight filter cylinder 1 and the enlarging awl filter cylinder 11 sealing gasket 117 is housed, as shown in Figure 2; The blowback self-cleaning device mainly is made of cylinder 9, winding-up valve 7, winding-up pipe 8, nozzle 6 and pressure pipe 2, winding-up pipe 8 is connected with cylinder 9 by winding-up valve 7, nozzle 6 is located on the winding-up pipe 8 and is corresponding with the outlet air end of each horizontal cartridge filter 17, control system 3 obtains pressure difference signal by the pressure pipe 2 of division board 13 both sides, by 8 foldings of magnetic valve group 10 control winding-up valves, compressed air enters double-drum filter through winding-up valve 8 by winding-up pipe 7 and nozzle 6 by cylinder 9 and realizes automatically cleaning; Cascade filtration device 5 is made up of several air cleaners.
During work, air is under the powerful negative pressure of air compressor machine, enter the one-level filter by inlet, most dust is filtered, be attached on the windward side of horizontal cartridge filter, dust constantly raises the resistance of horizontal cartridge filter, when resistance reaches a certain numerical value, control system is started working, it sends instruction opens winding-up valve 7, and the compressed air in cylinder 9 is sprayed onto through nozzle 6 on the inwall of enlarging awl filter cylinder 11 and straight filter cylinder 1 by winding-up pipe 8, vibrations and air-flow reserve motion take place in instantaneous filter cylinder, blowing off is attached to dust on the filter windward side, and the resistance of one-level filter descends thereupon, when resistance drops to a certain numerical value, control system stops blowback, and filter cylinder is worked in can be for a long time between the Resistance Level of setting so repeatedly; When the resistance of filter cylinder reaches setting value, just should be replaced.The cascade filtration device that is placed in thereafter of the superfine dust of being tackled by first order filter cylinder is not removed, and is connected the change in resistance situation of the Pressure gauge 4 on the cascade filtration device by observation, determines whether to change the cascade filtration device.
