For realizing above-mentioned purpose; Design a kind of screw compression host machine of integrated funnel-shaped crude oil separation structure; Comprise the helical lobe compressor host, oil gas tube, olein separator, the airflow baffle that are connected with the exhaust shaft bearing; It is characterized in that: the helical lobe compressor host below is provided with the casing urceolus, and the outer tube bottom of casing adopts fastening piece to connect the upper end of oil gas tube, and the casing of the rotor chamber bottom of helical lobe compressor host is positioned at the inner chamber of casing urceolus; The casing of rotor chamber bottom has the funnel that crude separation is used; The sidewall of funnel is provided with vent, and an end of outlet pipe penetrates from the bell mouth of funnel bottom and places funnel inner chamber, the other end of outlet pipe to pass the import that connects the olein separator behind the oil gas tube sidewall; To the exhaust passage of vertically establishing a kink shape, the lower end mouth of exhaust passage connects the casing outer tube side wall from the exhaust ports of exhaust shaft bearing, and the relief opening of upper end, exhaust passage connects rotor chamber like this, the lower end mouth perforation casing outer tube side wall of exhaust passage.
The casing of described funnel, casing urceolus and helical lobe compressor host is an integral type.
The lural center of circle with funnel bottom is the center of circle, and vent is positioned on the concentric circle at counterclockwise 270 ℃ of direction places of exhaust passage lower end mouth.
And be provided with an airflow baffle between the casing urceolus tapping of exhaust passage lower end mouth perforation place and the outer wall of funnel.
The present invention compares with existing technology, and employing and casing funnel cast in block are as the crude separation parts, and be not only simple in structure, and level of integration is high, saves cost; And helical lobe compressor host adopts bolt to be connected with barrel of oil and gas, need not to connect flexible pipe, and barrel of oil and gas is only made oil tank and used, and the barrel of oil and gas volume dwindles significantly, and complete machine takes up space and also reduces significantly, and thick oil separates effective.

[embodiment]
Below in conjunction with accompanying drawing the present invention is further described.
Referring to Fig. 1 and Fig. 2, the helical lobe compressor host 16 that connects exhaust shaft bearing 2 mainly is made up of male rotor 3 in the casing 1 that is provided with intakeport 12 and rotor chamber 15, the rotor chamber and female rotor 4; Helical lobe compressor host 16 belows are provided with casing urceolus 9; Casing urceolus 9 bottoms adopt fastening piece such as bolt etc. directly to connect the upper end of oil gas tube 6; The casing of rotor chamber 15 bottoms of helical lobe compressor host is positioned at the inner chamber of casing urceolus 9; The casing of rotor chamber bottom has the funnel 8 that crude separation is used; The sidewall of funnel 8 is provided with vent 10, and an end of outlet pipe 7 penetrates from the bell mouth of funnel 8 bottoms and places funnel 8 inner chambers, the other end of outlet pipe 7 to pass the import that connects olein separator 5 behind oil gas tube 6 sidewalls; Begin to the exhaust passage 13 of vertically establishing a kink shape similar " C " font from the exhaust ports of original exhaust shaft bearing; The upper/lower terminal mouth of exhaust passage 13 connects the rotor chamber 15 of helical lobe compressor host and casing urceolus 9 sidewalls of rotor chamber below respectively, and wherein the upper end-hole of exhaust passage 13 also is the relief opening of original exhaust shaft bearing; Described funnel 8, casing urceolus 9 are integral type with the casing of helical lobe compressor host 16;
And be provided with between the tapping on the casing urceolus 9 of exhaust passage 13 lower end mouth perforations place and the outer wall of funnel 8 one counterclockwise to airflow baffle 14, through this airflow baffle, gas is caused casing urceolus 9 and is rotated with 8 in funnel and separates;
The center of circle with the bell mouth 11 of funnel 8 bottoms is the center of circle, and vent 10 is positioned on the concentric circle at counterclockwise 270 ℃ of direction places of exhaust passage 13 lower end mouth.
During work, when driving male rotor 3 rotations, its spiral gear promotes female rotor 4 and rotates simultaneously; Suck low-pressure air from intakeport 12 continuously, in casing 1, in rotor chamber 15, spray into lubricant oil simultaneously, along with the rotation of negative and positive rotor; It is compressed into the gas mixture of high pressure, and in the relief opening of the upper end of entering exhaust passage 13, this moment, exhaust passage 13 interior gases were gas mixtures of high pressure; After needing gas mixture separated through crude separation and smart separation of double, the pressurized air that oil content is very low just can be drawn and supplied the user to use, and its crude separation process is following: gas mixture is discharged from the lower end mouth of the exhaust passage 13 that is positioned at exhaust shaft bearing 2; Get into 8 in casing urceolus 9 and funnel; Carry out baffling through airflow baffle 14 to counterclockwise position, be rotated counterclockwise in the passage of gas mixture between casing urceolus 9 and funnel 8, referring to direction shown in Fig. 3 hollow core arrow; Air-flow is from 0 ° of-90 ° of-180 ° of-270 ° of direction high speed rotating; Be after air-flow rotates about 3/4 circle, to get in the funnel 8 through the vent on the sidewall of funnel 8 10, the air-flow of the high-pressure air after the process crude separation gets into olein separators 5 through outlet pipe 7 to carry out discharging after essence is separated; Bigger oil droplet is got rid of on the inwall of casing urceolus 9 owing to centrifugal force, then in inwall falls to barrel of oil and gas 6.
