Abstract
The utility model discloses a self-cleaning type filter unit of an air compressor. The self-cleaning type filter unit comprises a filter cartridge, a back flushing device arranged above the filter cartridge and a sealing device arranged on the periphery of the filter cartridge as well as upper and lower box-type devices, wherein the upper box-type device is in a structure with upper and lower openings; the lower box-type device is in a structure the upper end of which is open, the periphery of a box body of the upper box-type device is provided with a filter screen which is made of a non-woven fabric material, the peripheral edges with the open upper end of the box body of the upper box-type device are connected with the peripheral edges of the lower end of the sealing device on the periphery of the filter cartridge, and the peripheral edges with the open lower end of the upper box-type device are connected with the upper openings of the lower box-type device. The self-cleaning type filter unit provided by the utility model has the advantages that impurities with large volumes or large particles are effectively filtered, a condition that dust falling after back flushing is absorbed into the filter cartridge so as to cause 'secondary pollution' is avoided, the using cost is low, and the replacement is convenient.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of air compressor machine self cleaning filtering device.
Background technology
For guaranteeing the normal operation of air compressor machine, oxygen company air compression station generally is provided with self cleaning filtering device, at first gas enter air compressor machine after self cleaning filtering device filters, when the inlet outlet pressure differential that filters device surpasses setting, control system will start back-blowing device, to filter blowback one by one, thereby the dust on filter surface is come off.But, in existing filter, the air-flow that these dusts are often followed again air is drawn onto filter surfaces, form secondary pollution, do not have the blowback effect.Thereby blowback is not just carried out in some station.Finally, the dust of filter surface aggregation is too many, cause that the air compressor machine suction pressure is low, affect the normal operation of equipment, the place that some dust is large at pressure reduction penetrates filter, enter air compressor machine, accumulate on impeller, affected the dynamic balancing of impeller, thereby cause vibration high, the air compressor machine made often occurs to stop and overhauls, and what impact was produced normally carries out.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of air compressor machine self cleaning filtering device, and this filter can effectively filter out larger impurity in gas and again be inhaled into filter with the dust of avoiding blowback to come off, causes secondary " pollution ".
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of air compressor machine self cleaning filtering device, comprise cartridge filter, be arranged on the back-blowing device of cartridge filter top and be arranged on cartridge filter sealing device on every side, its special feature is, it also comprises upper and lower two chamber installations, wherein going up chamber installation is upper lower open mouth structure, the box type device is the uncovered structure in upper end, the casing surrounding of described upper chamber installation is the nonwoven cloth material screen pack, and uncovered surrounding, its upper end is connected with the surrounding of cartridge filter sealing device lower end on every side respectively, uncovered surrounding, its lower end is connected with the upper end of described box type device is uncovered.
Further, the bottom of described box type device is provided with osculum.
The utlity model has following major advantage:
The filter effect of one, enhancing air compressor machine self cleaning filtering device, the upper chamber installation that is the nonwoven cloth material screen pack by the casing surrounding filters out leaf, plastic paper and other volume or the larger impurity of particle in advance;
Two, in the situation that the box type bottom of device is put into a small amount of water, the dust that can effectively avoid blowback to come off is inhaled into cartridge filter again, causes secondary " pollution ";
Three, upper chamber installation can conveniently be installed and removed, and when on the nonwoven of surrounding, dust is more, can take off, and it is reusable that bullet falls dust, when nonwoven reaches service life, also can conveniently replace.
The accompanying drawing explanation
The air compressor machine self cleaning filtering device partial sectional view that Fig. 1 is prior art.
Fig. 2 is air compressor machine self cleaning filtering device partial sectional view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
From Fig. 1 and Fig. 2, can find out, the air compressor machine self cleaning filtering device of the utility model and prior art all comprises the back-blowing device 2 that is arranged on cartridge filter 1 top and is arranged on cartridge filter 1 sealing device 3 on every side.Unlike the prior art, the utility model also comprises upper and lower two chamber installations 4,5, wherein going up chamber installation 4 is upper lower open mouth structure, box type device 5 is the uncovered structure in upper end, the casing surrounding of described upper chamber installation 4 is the nonwoven cloth material screen pack, and uncovered surrounding, upper end is connected with the surrounding of cartridge filter 1 sealing device 3 lower ends on every side respectively, and uncovered surrounding, lower end is connected with the upper end of described box type device 5 is uncovered.In this specific embodiment, the nonwoven cloth material screen pack of upper chamber installation 4 has been made the aluminium plastic window between sealing device 3 and box type device 5, is convenient to like this clean and change screen pack; Also nonwoven cloth material directly can be followed closely on the surrounding of sealing device 3 and box type device, although so simply be unfavorable for changeing.The gas sucked is before entering air compressor machine, and at first the nonwoven screen pack by upper chamber installation 4 filters out leaf, plastic paper and other volume or the larger impurity of particle in advance, and then further filters through filter cylinder 1.For what seal, so can inject therein some water, form pond due to box type device 5 bottoms, dust after blowback is due to Action of Gravity Field, fall in water and remove, thereby the dust of avoiding blowback to come off is inhaled into cartridge filter 1 again, causes secondary " pollution ".Box type device 5 bottoms can be both independently sealing plates, also can directly utilize the bottom of ground as box type device 5.Bottom at box type device 5 also can be provided with osculum 6, can regularly to the mud in pond, be cleared up like this, avoids the generation of bacterium, contaminated environment.While usually normally using, osculum 6 use stoppers are blocked, stopper is extracted during cleaning.Because the contained dust of gas after upper chamber installation 4 filters is not a lot, so box type device 5 can arrange to such an extent that be not very high.
Claims (2)
1. an air compressor machine self cleaning filtering device, comprise cartridge filter (1), be arranged on the back-blowing device (2) of cartridge filter (1) top and be arranged on cartridge filter (1) sealing device (3) on every side, it is characterized in that: it also comprises upper and lower two chamber installations, wherein going up chamber installation (4) is upper lower open mouth structure, box type device (5) is the uncovered structure in upper end, the casing surrounding of described upper chamber installation (4) is the nonwoven cloth material screen pack, and uncovered surrounding, its upper end is connected with the surrounding of cartridge filter (1) sealing device (3) lower end on every side respectively, uncovered being connected of upper end of uncovered surrounding, its lower end and described box type device (5).
