Abstract
The utility model discloses a combined air filter, which is characterized in that a first sponge coarse filter and a second sponge coarse filter are respectively arranged in an air filtering chamber; the air outlets of the first and the second sponge coarse filters are respectively connected into an air inlet pipeline through a first check valve and a second check valve; a stainless steel mesh fine filter is arranged at an air inlet of a compressor; and the air inlet pipeline is connected with the air inlet of the stainless steel mesh fine filter. According to the combined air filter provided by the utility model, as multilayered filtering is provided, the cleanliness of the air is ensured; and the structure is simple, the maintenance is easy and the use cost is low.
Description
Technical field:
The utility model relates to a kind of combination type air filter, is specially adapted to air screw compressor.
Background technology
When air screw compressor was applied to various environment, common this environment may be with being inhaled in the compressor and finally being transported to dust and chip in the apparatus with pressurized air stream; Dust in the compressed air and chip may dirty apparatus parts or are become entrained in the air and be transmitted, thus the pollution engineering project; In addition, airborne dust and chip are inhaled into compressor possibility increasing friction force, shorten the average life span of compressor itself.
Air screw compressor air intake filter of the prior art is comprised of a housing and a lid, and a filter core is arranged in housing; But in the larger working environment of dust, the filter core that price is very expensive needs often to change, and this situation has increased production cost greatly.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of combination type air filter being provided, to reduce the production cost of air screw compressor.
The utility model is that the technical solution problem adopts following technical scheme:
The design feature of the utility model combination type air filter is: in the filter air chamber the first cavernous body coarse filter and the second cavernous body coarse filter are set respectively, the gas outlet of described the first cavernous body coarse filter and the second cavernous body coarse filter is respectively by the first stop valve and the second stop valve access admission line, air inlet at compressor arranges the stainless steel cloth fine filter, and described admission line is connected to the air inlet of described stainless steel cloth fine filter.
The design feature of the utility model combination type air filter also is:
The sponge thickness of described cavernous body coarse filter is 4mm-5mm.
Described stainless steel cloth fine filter is Wrapping formed by 120 purpose stainless steel cloths.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model multiple filtration has guaranteed the cleanliness factor of air;
2, the utility model is selectively to work with the first cavernous body coarse filter and the second cavernous body coarse filter, when one of them need to clean, closing corresponding one tunnel stop valve removes it, opening another road stop valve devotes oneself to work another road cavernous body coarse filter, such form can prolong the stream time of stainless steel cloth fine filter greatly, thereby reduces production costs.
Description of drawings
Fig. 1 is the utility model structural representation;
Number in the figure: 11 first cavernous body coarse filters; 12 second cavernous body coarse filters; 21 first stop valves; 22 second stop valves; 3 admission lines; 4 compressors; 5 stainless steel cloth fine filters; 6 filter air chambers.
The specific embodiment
Referring to Fig. 1, the combination type air filter is in filter air chamber 6 the first cavernous body coarse filter 11 and the second cavernous body coarse filter 12 to be set respectively in the present embodiment, the gas outlet of the first cavernous body coarse filter 11 and the second cavernous body coarse filter 12 is respectively by the first stop valve 21 and the second stop valve 22 access admission lines 3, air inlet at compressor 4 arranges stainless steel cloth fine filter 5, and admission line 3 is connected to the air inlet of stainless steel cloth fine filter 5.
In the implementation, the sponge thickness of cavernous body coarse filter is 4mm-5mm, and stainless steel cloth fine filter 5 is Wrapping formed by 120 purpose stainless steel cloths.The filter air chamber needs sealing, the energy rain-proof dust-proof, and with ground floor filtration of its formation to air, cavernous body coarse filter thereafter and stainless steel cloth fine filter form respectively the second layer and filter and three layer filtration, and the form of this multiple filtration has guaranteed the filtering effect.
Two-way cavernous body coarse filter is set in the present embodiment, and by stop valve it is selectively devoted oneself to work.When air screw compressor normally moves, the first stop valve and the second stop valve are that a unlatching one is closed, suction because of the generation of air screw compressor air inlet, air is inhaled into the road cavernous body coarse filter that stop valve is opened by the filter air chamber of dried and clean, enter in the stainless steel cloth fine filter by admission line again, finally enter compressor.
When the road cavernous body coarse filter that is chosen as duty need to be changed cleaning, close this road stop valve it is removed; Open another road stop valve, another road cavernous body coarse filter is devoted oneself to work, can greatly prolong like this stream time of stainless steel cloth fine filter.
Two-way cavernous body coarse filter also can adopt the occupation mode of periodic replacement, and the stainless steel cloth fine filter is set to the occupation mode of periodic cleaning.
