Abstract
The invention relates to an air filter system of a movable screw compressor. An air filter connected with a compressor host is arranged in a vehicle body, and the top of the vehicle body is provided with a coarse filter system which is connected with the air filter through a connecting pipe. The front end of the air filter is provided with the coarse filter system, so the environmental air is filtered twice by the coarse filter system and the air filter so as to improve the filter effect of the air and improve the service life of the air filter. A filter layer of the coarse filter system consists of a filter core inserted in a guide groove, and the filter layer can be extracted from the guide groove, so the filter layer is convenient to assemble, disassemble and clean. The outside of the filter core is also provided with a locking mechanism which is tightly supported by adopting spring force with good effects of preventing vibration and loosening.
Description
(1) technical field
The present invention relates to a kind of air filtering system of movable screw compressor, be applied in the air-channel system of movable screw compressor.
(2) background technique
Movable screw compressor generally is used for field work, and surrounding environment is poor, and more dust is arranged.Cleaner for the air of guaranteeing to enter compressor, the suction port at compressor adds air filter usually.
Existing movable screw compressor, its air filtering system have only one-level to filter usually, and ambient air enters and enters compressor again after air filter filters.This air filtering system has the following disadvantages: 1, the filtering material in the air filter is very easy to stop up, and the life-span is short; 2, air filter cleans inconvenient; 3, because of compressor has the casing parcel, the air filter mounting or dismounting are very inconvenient.
(3) summary of the invention
The present invention is directed to the problems referred to above, a kind of air filtering system of not susceptible to plugging movable screw compressor is provided.
Technological scheme of the present invention is such: a kind of air filtering system of movable screw compressor, in car body, be provided with the air filter that links to each other with compressor host, the top of described car body is provided with the coarse filtration system, and this coarse filtration system links to each other with described air filter by taking over.
The further technological scheme of the present invention is:
Described coarse filtration system is made of the intake grill that is linked in sequence, filter layer and air collection chamber, and the bottom of described air collection chamber is provided with exhaust outlet.Described filter layer is made of the filter core that is plugged in the guiding groove, and described guiding groove is fixed on the top of described air collection chamber.Described filter core is made of framework and the filtering material that is fixed in the described framework.Described filtering material folds.Described filter core is divided into two.
The arranged outside of described filter core has locking mechanism.Described locking mechanism by bolt, spring, reinforcement pad, compress dead bolt and nut constitutes, described spring is at bolt head and strengthen between the pad, described bolt passes the housing of described air collection chamber and compresses dead bolt and fixed by nut.The described dead bolt that compresses is provided with stop screw, and the housing of described air collection chamber is provided with spherical pit, and the bulb projection of described stop screw matches with described spherical pit.
Compared with the prior art the present invention has the following advantages:
1, the present invention is provided with the coarse filtration system at the front end of air filter, and ambient air has improved the filtering effect of air, the working life of having improved air filter through coarse filtration system and twice filtration of air filter.
2, coarse filtration system is installed in the top of car body, and ambient air is better relatively.
The filter layer of 3, coarse filtration system can be extracted out in guiding groove, and mounting or dismounting and cleaning are convenient.
4, locking mechanism adopts spring force to prop up tightly, and the vibrationproof anti-loosing effect is good.
5, the location of locking mechanism adopts spherical pit to cooperate with the bulb projection, and is convenient and reliable.

(5) embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
See Fig. 1, the present invention is a kind of air filtering system of movable screw compressor.In the car body 5 of movable screw compressor, be provided with the air filter 4 that links to each other with compressor host 1.Be provided with coarse filtration system 2 at the top of car body 5, this coarse filtration system 2 links to each other with air filter 4 by taking over 3.The present invention is provided with coarse filtration system 2 at the front end of air filter 4, and ambient air has improved the filtering effect of air, the working life of having improved air filter 4 through coarse filtration system 2 and air filter 4 twice filtration.
As Fig. 2～shown in Figure 5, described coarse filtration system 2 is made of the intake grill 6 that is linked in sequence, filter layer 7 and air collection chamber 8.Be provided with exhaust outlet 9 in the bottom of air collection chamber 8, exhaust outlet 9 links to each other with an end of taking over 3.Described filter layer 7 is made of the filter core 11,12 that is plugged in the guiding groove 13, and filter layer 7 can be extracted out in guiding groove 13, the convenient cleaning.Guiding groove 13 is fixed on the top 14 of air collection chamber 8.Described filter core 11,12 is made of framework and the filtering material that is fixed in the framework.Filtering material folds, and can increase filter area.About described filter core is divided into two, i.e. filter core 11 and filter core 12.
In order to prevent that filter layer 7 from skidding off in guiding groove 13, locking mechanism 10 is arranged in the arranged outside of filter core 11,12.Described locking mechanism 10 by bolt 19, spring 15, strengthen pad 16, compress dead bolt 17 and nut 18 constitutes, spring 15 is between 15 on bolt and reinforcement pad 16.Bolt 15 passes the housing of air collection chamber 8 and compresses dead bolt 17 and fixing by nut 18.
Time vibration causes locking mechanism 10 rotation displacements in order to prevent work, compress dead bolt 17 and be provided with stop screw 20, the housing of air collection chamber 8 is provided with spherical pit 22, and the bulb projection 21 of stop screw 20 matches with described spherical pit 22, makes locking mechanism 10 location.
