The filter element (8) is a coalescence filter element, and the precision of the coalescence filter element can reach 3 micrometers. The lower base (1) and the upper end cover (3) are fixed on the shell (2) through threads, and sealing gaskets are arranged between the lower base (1), the upper end cover (3) and the shell (2). The air inlet (4) and the air outlet (5) are both provided with internal threads for connecting an air pipeline.
The utility model discloses has following effect: according to the technical scheme, the filter element with the precision reaching 3 microns and the coalescence function is adopted, so that the oil-gas separation effect is better, and the service life is longer; the threaded connection mode of the lower base, the shell and the upper end cover is adopted, so that the filter element can be replaced or the cleaning operation can be facilitated.
Drawings
Fig. 1 is a main sectional view of the present invention.
Description of the drawings: 1. a lower base; 2. a housing; 3. an upper end cover; 4. an air inlet; 5. an air outlet; 6. a through opening; 7. an oil discharge port; 8. a filter element; 9. a screw.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1, an oil-gas separation filter, a lower base 1 of which is fixed at the lower end of a cylindrical housing 2, and the side of the lower base 1 is provided with an air inlet 4, a through hole 6 is arranged at the central position of the upper surface of the lower base 1 and is communicated with the air inlet 4, the through hole 6 protrudes out of the upper surface of the lower base 1, an oil groove is formed between the inner wall of the housing 2 and the outer side of the protruding part, one end of an oil discharge port 7 is arranged at the side of the lower base 1, and the other end is arranged in the oil groove; the upper end cover 3 is fixed at the upper end of the shell 2, the air outlet 5 is arranged on the side surface of the upper end cover 3, the upper end of the screw 9 is screwed into the central position of the upper end cover 3, and the lower end of the screw is provided with internal threads; the filter element 8 is vertically arranged in the shell 2, the bottom of the filter element 8 is communicated with the through hole 6 in a sealing way, and the top of the filter element 8 is closed and screwed into the internal thread of the screw 9 through a screw.
The lower base 1 and the upper end cover 3 are fixed on the shell 2 through threads, and sealing gaskets are arranged between the lower base 1, the upper end cover 3 and the shell 2. When replacing the filter element 8 or maintaining and cleaning the device, only the above-mentioned screw thread needs to be removed. And the sealing gasket plays a role in sealing the device.
