Description

Technical Field

[0001] This utility model relates to a filter element replacement tool, and more particularly to a special tool for replacing the lubricating oil filter element of a screw compressor. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] The screw compressor lubricating oil filter is used to filter impurities in the lubricating oil, ensuring its cleanliness and good lubrication performance. The filter chamber is a cylinder with an inner diameter of φ=437mm and a length of L=1300mm, with only one flange that can be opened. The chamber is used to install a cylindrical oil filter element with a diameter of φ=377mm and a length of L=1211mm. The oil filter element must be axially aligned with a positioning hole with a diameter of φ=387mm inside the chamber, with a 5mm clearance between the oil filter element and the positioning hole. During routine oil filter element replacement, maintenance personnel push the oil filter element in from one side of the chamber. Due to the confined space and obstructed view, maintenance personnel cannot observe the relative position of the oil filter element and the positioning hole, and can only rely on feel to slowly try to push the oil filter element into the positioning hole. This process consumes a lot of time, severely reducing maintenance efficiency. Furthermore, the oil filter element may collide with the positioning hole during the pushing process, easily causing deformation of the oil filter element.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0024] Figure 2 This is a bottom view of the present invention.

[0025] Figure 3 This is a side view of the present invention.

[0026] In the diagram, 1 is the bracket, 2 is the height adjustment device, 3 is the handle; 11 is the hollow part, 21 is the bolt seat, 22 is the bolt, 31 is the connecting rod, and 32 is the handle rod. Detailed Implementation

[0027] The general concept of this utility model is as follows: to design a special tool for replacing the lubricating oil filter element of a screw compressor, with the following objectives:

[0028] 1. Adjust the bolt length to meet the clearance requirements between the oil filter element and the positioning hole;

[0029] 2. During the process of pushing the oil filter element into the positioning hole, collision between the oil filter element and the positioning hole is avoided.

[0030] The overall technical solution of this utility model is as follows: Figure 1 As shown, it includes:

[0031] Bracket 1, the top surface of bracket 1 is used to horizontally support the cylindrical oil filter element in the lubricating oil filter of the screw compressor, and the size of bracket 1 is designed according to the external size of the cylindrical oil filter element.

[0032] A handle 3 is fixed at one end of the bracket 1 for dragging the bracket 1 horizontally, thereby feeding the cylindrical oil filter element into the screw compressor lubricating oil filter.

[0033] The bottom of the bracket 1 is equipped with a height adjustment device 2, which is used to adjust the height of the bracket 1 in the screw compressor lubricating oil filter, so as to align the cylindrical oil filter element with the installation position.

[0034] like Figure 2 As shown, the handle 3 includes a connecting rod 31 fixedly connected to one end of the bracket 1, and the connecting rod 31 is installed along the central axis of the bracket 1; the other end of the connecting rod 31 is fixedly provided with a handle 32, which is convenient for the operator to hold manually.

[0035] The bracket 1 is an arc-shaped thin sheet with a hollowed-out section 11 along the central axis, which can reduce weight and material without reducing strength.

[0036] like Figure 3 As shown, the height adjustment device 2 includes a bolt seat 21 located at the bottom of the bracket 1, and the bolt seat 21 is threadedly connected to a bolt 22. In use, tightening the bolt 22 adjusts the height of the bracket 1 within the screw compressor lubricating oil filter.

[0037] One bolt seat 21 and one bolt 22 form a group, and multiple groups can be designed according to actual needs.

[0038] Example 1:

[0039] In one embodiment, the special tool consists of a bracket 1, a handle 3, and an adjusting bolt assembly 2. The bracket 1 is made of carbon steel and is used to support the oil filter element. The handle 3 is also made of carbon steel and is used to push the oil filter element into the positioning hole. The adjusting bolt assembly 2 is made of carbon steel and is used to adjust the support height to meet the fitting clearance requirements between different oil filter elements and the positioning hole. The specific solution is as follows:

[0040] A special tool is designed based on the shape of the oil filter element. The tool consists of two 3mm thick curved flat steel bars and two 3mm thick straight flat steel bars, which are welded together to form a frame. A handle 3 is welded in the middle of the curved flat steel bar to facilitate the operator in pushing the oil filter element in. Four adjusting bolt assemblies 2 are installed below the curved flat steel bar to support the special tool against the inner wall of the cavity.

[0041] When using: When replacing the oil filter element, first adjust the bolt height to meet the fitting clearance between the oil filter element and the positioning hole. Then, place the oil filter element horizontally on the special tool, hold the handle and gently push the special tool into the cavity. The oil filter element will then enter the cavity together. When it is pushed all the way, push the oil filter element into the positioning hole.

[0042] Example 2:

[0043] A slider (not shown in the figure) that works with this tool can be placed under the oil filter element through the hollow part 11, making it easier to push the oil filter element in.
