Description

oil separator filter assembly

technical field

The utility model belongs to the field of refrigeration system devices, especially related to the oil separator filter assembly.

Background technique

Existing oil separators include a tank body, an air intake pipe assembly, an air outlet pipe assembly, a filter screen assembly, and a rotary separation device. The edge of the net is pressed against the outer ring pressing sheet and the filter screen support and fixed by spot welding between the filter screen support and the outer ring pressing sheet. There is a protrusion in the center of the filter screen support, and the center of the filter screen support is arranged along the circumferential direction around the protrusion. There are many holes evenly distributed. When the filter screen assembly is press-fitted into the tank, the force of the protrusions will easily disengage the solder joints on the filter screen bracket and the outer ring pressing piece, so that the filter screen bracket and the outer ring pressing piece will be separated, increasing The assembly scrap rate of the oil separator is improved.

Utility model content

The purpose of the utility model is to overcome the defect that the filter screen assembly of the existing oil separator has poor firmness in the assembly process, and to provide a filter screen assembly of the oil separator with good firmness.

For this reason, the utility model adopts the following technical solutions: the filter screen assembly of the oil separator includes a sheet filter screen, a filter screen bracket and an outer ring pressing piece, the filter screen bracket is a disc shape with a central protrusion, and the There are a plurality of holes evenly distributed in the circumferential direction, and the edge of the sheet filter is fixed by pressing against the filter bracket and the outer ring pressing sheet, and it is characterized in that the outer ring of the filter bracket and the sheet filter Both are provided with downwardly extending flanging, and the flanging of the sheet filter is attached to the outside of the flanging of the filter support, and the outer ring pressing piece includes an integrally formed ring part, a round pipe part and a ring presser foot , the ring part is arranged at one end of the round tube part, and the ring part and the round tube part are respectively pressed against the edge part of the sheet filter and the outside of the flanging of the sheet filter, and the ring presser foot is L-shaped, relatively The short side is fixedly connected to the other end of the round pipe part, and the longer side of the annular presser foot is spaced a certain distance from the inner wall of the round pipe part, so that the annular presser foot and the round pipe part form an annular groove cavity, and the filter screen support and the flanging of the sheet filter are embedded in the annular groove cavity, the filter bracket and the ring portion of the outer ring pressing piece are fixedly connected by spot welding, and the presser foot of the outer ring pressing piece is connected to the The flanging of the filter screen bracket and the round pipe part of the outer ring pressing sheet are fixedly connected by spot welding, which improves the overall assembly firmness of the filter screen assembly and avoids the filter screen bracket and the filter screen assembly being pressed into the tank. The outer ring pressing piece is detached.

Using the utility model can achieve the following beneficial effects: by fixing and pressing the flange of the filter screen bracket and the sheet filter screen into the annular groove cavity composed of the ring presser foot and the round tube part on the outer ring pressing piece, the filtration efficiency is improved. The firmness of the overall assembly of the screen assembly, when the filter screen assembly is press-fitted into the tank, effectively prevents the filter screen bracket and the outer ring pressing piece from being separated due to the disengagement of the solder joints, reducing the assembly scrap rate of the oil separator.

FIG. 2 is a schematic cross-sectional view along line A-A of FIG. 1 .

Detailed ways

Specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 2, the utility model includes a sheet filter 3, a filter support 1 and an outer ring pressing sheet 2. The filter support 1 is a disc shape with a central protrusion, and is surrounded by the protrusion along the circumferential direction. A plurality of holes are evenly distributed, and the outer rings of the filter screen support 1 and the sheet filter screen 3 are provided with flanges extending downward, and the flanges of the sheet filter screen 3 are attached to the flanges of the filter screen support 1. On the outside, the outer ring pressing piece 2 includes an integrally formed ring part, a round pipe part and an annular presser foot 4, and the edge of the sheet filter 3 passes through the filter screen support 1 and the outer ring pressing piece 2 The ring part is fixed against the pressure, and the ring part is arranged at one end of the round tube part, and the ring part and the round tube part are respectively pressed against the edge of the sheet filter 3 and the outside of the flanging of the sheet filter 3 , the annular presser foot 4 is L-shaped, and the shorter side is fixedly connected to the other end of the circular tube part, and the longer side of the annular presser foot 4 is spaced from the inner wall of the circular tube part by a certain distance, so that the annular presser foot 4 and the circular tube part form a An annular groove cavity, the flange of the filter screen support 1 and the sheet filter screen 3 is embedded in the annular groove cavity, the filter screen support 1 and the ring part of the outer ring pressing piece 2 They are fixedly connected by spot welding, and the annular presser foot 4 of the outer ring pressing piece 2 is fixedly connected with the flanging of the filter screen support 1 and the round pipe part of the outer ring pressing piece 2, which improves the filter screen assembly. The firmness of the overall assembly prevents the filter screen support 1 and the outer ring pressing piece 2 from detaching when the filter screen assembly is press-fitted into the tank.
