Description
Technical Field
The utility model belongs to the technical field of rotary blower equipment, especially, rotary blower uses gas oil separator.
Background
The rotary fan is a positive displacement fan, has the characteristics of forced conveying constant torque pneumatics, and has higher volumetric efficiency, lower leakage rate and lower noise compared with a Roots fan.
The rotary blower makes the working volume alternatively enlarged and reduced by means of the rotary motion of the rotor in the casing, so as to suck gas and raise the gas pressure. Because the rotary blower needs to use lubricating oil to lubricate the machine body in the running process, but the lubricating oil is inevitably evaporated due to the high temperature generated by compression of the rotary blower, certain oil mist can be contained in the discharged air, an air-oil mixture can be generated, and the environment can be directly polluted.
SUMMERY OF THE UTILITY MODEL
In order to overcome among the prior art rotary air-blower compressed gas produces the oil mist, the defect of polluted environment, the utility model provides an oil separator for rotary air-blower can separate the oil in the gas, reaches the clean effect of air.
The utility model provides a technical scheme that its technical problem adopted is: an air oil separating device for a rotary blower is characterized in that: including the casing both ends are equipped with respectively about the casing and connect inside manometer disk seat, the oil extraction mouth upper portion is equipped with fixed upper filter screen, lower part in the casing is equipped with fixed lower floor's filter screen, and the air inlet pipeline runs through the casing side and extends to the position that is close to lower floor's filter screen between inside lower floor's filter screen of casing and the upper filter screen, and the exhaust pipeline runs through the casing lower extreme and extends to the position of the inside upper filter screen upper surface of casing.
Preferably, the centers of the oil discharge nozzle, the lower layer filter screen, the upper layer filter screen and the pressure gauge valve seat are positioned on the same axis.
Preferably, the air inlet pipeline and the exhaust pipeline are arranged on corresponding sides of the shell.
Preferably, the through holes of the lower filter screen and the upper filter screen are conical through holes.
Preferably, the lower filter screen and the upper filter screen are arranged in a symmetrical mirror image mode.
Compared with the prior art, the utility model discloses the beneficial effect who has: the utility model discloses in, get into high-pressure oily gas by the air inlet pipe way, spray the back on the lower floor's filter screen, through the first oil-gas separation. At the moment, the oil subjected to primary filtration descends due to gravity, the gas rises to fill the whole cavity, secondary filtration is carried out through the upper filter screen, the oil subjected to secondary filtration descends due to gravity to obtain double-layer filtered clean air, and the clean air enters the exhaust pipeline and enters the system pipe network to reach the working condition.
Drawings
The following description of the present invention will be made with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of a semi-sectional structure of an air-oil separator for a rotary blower according to the present invention;
in the figure: the oil-gas separator comprises a shell 1, an air inlet pipeline 2, an oil discharge nozzle 3, an exhaust pipeline 4, a lower-layer filter screen 5, an upper-layer filter screen 6 and a pressure gauge valve seat 7.
Detailed Description
In order to make the technical solution and the advantageous effects of the present invention more clear, the following detailed description of the present invention is provided in conjunction with the following embodiments.
The utility model discloses a gas oil separator for rotary blower, refer to fig. 1, it includes casing 1, both ends are equipped with respectively and connect 1 inside manometer disk seat 7 of casing about casing 1, oil extraction nozzle 3, upper portion is equipped with fixed upper filter screen 6 in casing 1, the lower part is equipped with fixed lower floor's filter screen 5, air inlet pipe 2 runs through casing 1 side and extends to and is close to the position of lower floor's filter screen 5 between 1 inside lower floor's filter screen 5 of casing and the upper filter screen 6, exhaust pipe 4 runs through the position of 1 lower extreme of casing and extends to the 6 upper surface of 1 inside upper filter screen of casing, oil extraction nozzle 3, lower floor's filter screen 5, upper filter screen 6, the center of manometer disk seat 7 is on the same axis, get into high-pressure oily gas by air inlet pipe 2, spray on lower floor's filter screen 5 after, through first oil-gas separation. At the moment, the oil subjected to primary filtration descends due to gravity, the gas rises to fill the whole cavity, secondary filtration is carried out through the upper filter screen 6, the oil subjected to secondary filtration descends due to gravity to obtain double-layer filtered clean air, and the clean air enters the exhaust pipeline 4, enters the system official network and reaches the working condition.
The inlet line 2 and the outlet line 4 are located on respective sides of the housing 1. On the one hand, each part of the equipment is convenient to uniformly install and set, on the other hand, the flow in the cavity can be increased, the air flow is slowed down, the filtering time is prolonged, and the filtering is thorough.
The through holes of the lower filter screen 5 and the upper filter screen 6 are conical through holes, and the lower filter screen 5 and the upper filter screen 6 are symmetrically arranged in a mirror image mode. In the ascending process of the gaseous oil mist mixture, on one hand, the oil can be attached to the upper surface of the lower filter screen 5 and the inner wall of the conical through hole, so that the gaseous oil mixture is gradually separated from the oil in the ascending process in an overturning manner, on the other hand, the oil can be attached to the lower surface of the upper filter screen 6 and the inner wall of the conical through hole to stop ascending, so that the gaseous oil mixture is gradually separated from the oil in the ascending process, and finally exhausted gas contains no oil as much as possible.
The gyration air-blower is when the operation, and casing and rotor friction need the oil lubrication, consequently through the gaseous oiliness of air-blower pressurization, the utility model discloses a gas-oil separator can separate the oil in the gas, reaches the clean effect of air.
It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only, not by way of limitation, since other embodiments will become apparent to those skilled in the art upon consideration of the following detailed description of the invention without any creative effort.
