Description
Technical field
The present invention relates to air compressor machine technical fields, specially screw-rod air compressor.
Background technique
Air compressor is a kind of equipment to compressed gas.Air compressor is similar with water pump structure.Most of skies
Air compressor is reciprocating-piston, rotating vane or rotary screw.Centrifugal compressor is very big application program.Wherein spiral shell
Bar air compressor machine only needs single power supply connection and compressed air connection using pre- complete configuration screw air compressor, and built-in
Cooling system enables installment work greatly simplified.Screw air compressor is high-effect with its, high efficiency, non-maintaining, highly reliable
The advantages that uniform provide good compressed air for all trades and professions.Screw air compressor uses pre- complete configuration,
Single power supply connection and compressed air connection, and built-in cooling system are only needed, enables installment work greatly simplified.
When in use, female rotor and male rotor inside screw-rod air compressor can constantly squeeze sky to screw-rod air compressor at present
Gas, and then the female rotor and male rotor made can generate high temperature after long time running, and if turned not in time to female rotor and sun
Son radiates, and female rotor and male rotor are after having put aside amount of heat, it may occur that deforms or cracks, and then yin is caused to turn
Son and male rotor damage, and existing cooling system can not directly cool down to female rotor and male rotor, and then cause to cool down
The cooling effect of system is greatly reduced, while existing screw-rod air compressor lacks filter device, and then the air made is a large amount of
Dust or small gravel enter in screw-rod air compressor, and then make female rotor and male rotor because of dust or small in air
There is pit or are corroded by dust in gravel, female rotor and male rotor surface.
Summary of the invention
The purpose of the present invention is to provide screw-rod air compressors, by the way that filter core and the second gas-guide tube is arranged by the ash in air
Dirt is filtered, and then is avoided because female rotor and male rotor directly turn female rotor and sun with dust or small gravel contact due to
There is the phenomenon that pit in the surface of son, while can increase the radiating efficiency of hood by the way that cooling fin is arranged in hood side wall, together
When due to being inlaid with copper core inside cooling fin and then the heat-transfer rate of cooling fin can be increased, by setting cooler bin can into
The air entered in hood cools down, and then the air entered in hood is enable directly to drop to female rotor and male rotor
Temperature, and then cooling effect is improved, and then avoid causes female rotor or male rotor because of high temperature since cooling effect is bad
And occur deforming or the phenomenon that surface cracks, while can do the air entered in hood by setting drying box
It is dry, and then avoid and cause corrosion to show female rotor or male rotor containing a large amount of moisture in air because entering in hood
As, while can be by the condensation water collection of condenser generation together by installation water storage barrel.
To achieve the above object, the invention provides the following technical scheme: screw-rod air compressor, including body, the body
Pedestal is arranged in bottom, and the internal body is arranged hood, installs male rotor inside the hood, the male rotor is nibbled with female rotor

And separated between the air receiver 12 and cavity 15 by partition 16, be inserted into escape pipe 19 inside the drying box 14, it is described go out
The outlet side of tracheae 19 is located in cavity 15, and the inlet end of the escape pipe 19 is connect with cooler bin 20, in the cooler bin 20
Condenser 21 is arranged in portion, and drainpipe 18 is arranged in 20 bottom of cooler bin, and 18 water outlet of drainpipe is inserted into water storage barrel 17,
The first gas-guide tube 22, the outlet side of 22 inlet end of the first gas-guide tube and the second gas-guide tube 23 are inserted into 20 side of cooler bin
Connection, the inlet end of second gas-guide tube 23 connect with the outlet side of the second air inlet pipe 25, second air inlet pipe 25 into
Gas end is equipped with filter core 24.
One the second through-hole 27 is set inside the partition 16, and three first through hole are arranged in 27 side of the second through-hole
26, and the escape pipe 19 is inserted into the second through-hole 27, and the overall diameter of the diameter and escape pipe 19 of second through-hole 27 is big
It is small identical, and active carbon is filled with inside the cavity 15, and between first air inlet pipe 11 and drying box 14 and escape pipe
In close connection between 19 and drying box 14, i.e., the air entered in hood 3 can be done by setting drying box 14
It is dry, and then avoid and female rotor 5 or male rotor 10 are caused to corrode containing a large amount of moisture in air because entering in hood 3
The phenomenon that.
In close connection between second gas-guide tube 23 and the first gas-guide tube 22, the second air inlet pipe 25, and described the
The shape of two gas-guide tubes 23 is in figure six, and first gas-guide tube 22 and escape pipe 19 are located at the two sides of cooler bin 20, in turn
Avoiding makes the surface of female rotor 5 and male rotor 10 because female rotor 5 and male rotor 10 are directly contacted with dust or small gravel
There is the phenomenon that pit.
3 side wall of hood is equipped with several cooling fins 9, and is welding between the cooling fin 9 and hood 3, and described

Or small gravel contacts and female rotor 5 and the surface of male rotor 10 is made the phenomenon that pit occur.
The male rotor 10 is located in the same datum plane with driving wheel 8, shaft coupling 7 and prime mover 13, and described
Axis device 7 and prime mover 13 are located at 3 outside of hood, and then make prime mover 13 that male rotor 10 and driving wheel 8 be driven to rotate.
Working principle: in use, driving driving wheel 8 and male rotor 10 to rotate by prime mover 13, and then make 8 band of driving wheel
Dynamic driven wheel 6 rotates, and then rotates female rotor 5, and then compress to the air inside hood 3, then compresses
Air is discharged from exhaust pipe 4, and when compressing to the air inside hood 3, outside air is into mistake for female rotor 5 and male rotor 10
When filter core 24 enters the second air inlet pipe 25, filter core 24 can be filtered the air, i.e., by the dust or molecule mistake in air
It filters out and, then the air in the second air inlet pipe 25 enters the second gas-guide tube 23, since the shape of the second gas-guide tube 23 is in " 6 " word
Shape, and then make air when by the second gas-guide tube 23, remaining dust can be deposited in the second gas-guide tube 23 in air, then
Air flows into cooler bin 20 after the first gas-guide tube 22 in second gas-guide tube 23, then flows into the air warp in cooler bin 20
It is flowed into escape pipe 19 after crossing the cooling of condenser 21, the condensed water that condenser 21 is generated when cooling down to cooler bin 20 is logical
Drainpipe 18 flow into water storage barrel 17 in, then in escape pipe 19 air after the drying of active carbon in cavity 15 from first through hole
26 flow into air receiver 12, then flow into the first air inlet pipe 11 in air receiver 12 by dry and cooling air, Jin Erliu
Enter in hood 3, it is lower due to flowing into air themperature in hood 3, and then female rotor 5 and male rotor 10 can be carried out quickly directly
Cooling, simultaneously because the dust in air is filtered by filter core 24 and the second gas-guide tube 23, and then avoid because of female rotor 5
It is directly contacted with dust or small gravel with male rotor 10 and the surface of female rotor 5 and male rotor 10 is made the phenomenon that pit occur,
The radiating efficiency of hood 3 can be increased by the way that cooling fin 9 is arranged in 3 side wall of hood simultaneously, simultaneously because inlaying inside cooling fin 9
There is copper core 28 and then the heat-transfer rate of cooling fin 9 can be increased.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
