Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter element connector technology, specifically a filter element connector that facilitates quick assembly and disassembly. Background Technology
[0002] In the field of industrial filtration, the quick installation and removal of filter cartridges is crucial for equipment maintenance and operational efficiency. Traditional filter cartridge fixing methods typically rely on screws for fastening, a design that has many drawbacks.
[0003] On the one hand, the process of fixing the filter element with screws is cumbersome, requiring tools to tighten or loosen the screws one by one, which is time-consuming and laborious. Especially in scenarios where the filter element needs to be replaced frequently, this inefficient disassembly and assembly method will significantly affect production efficiency.
[0004] While existing quick-release structures simplify the assembly and disassembly process to some extent, they often rely on complex mechanical structures, which not only increases manufacturing costs but also may lead to assembly and disassembly failures due to structural malfunctions. Furthermore, some quick-release structures lack sufficient sealing performance, failing to ensure a reliable seal between the filter element and the tube sheet, thus affecting the overall performance of the filtration system. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a fixing structure that enables quick and convenient disassembly and assembly of filter element connectors while ensuring sealing performance and structural reliability.
[0006] This utility model is achieved through the following technical solution: A filter element connector for easy and quick assembly and disassembly, comprising a filter element connector and a perforated plate, wherein the perforated plate has perforated plate holes, characterized in that the outer surface of the filter element connector is provided with a sealing structure for sealing the perforated plate holes, the outer surface of the filter element connector is provided with one or more flanges, the top of the perforated plate is provided with one or more T-shaped positioning posts, the flange is engaged with one side of the T-shaped positioning post after rotation, and the flange and the T-shaped positioning post are provided with a limiting structure for engaging the flange and the T-shaped positioning post.
[0007] A further technical solution involves creating a hollow space between two or more flanges.
[0008] In a further technical solution, the vertical cross-sectional shape of the T-shaped positioning post is T-shaped.
[0009] In a further technical solution, the number of T-shaped positioning posts is the same as the number of flanges.
[0010] A further technical solution is that the sealing structure includes an O-ring fixedly disposed on the outer surface of the filter element connector.
[0011] In a further technical solution, an annular groove is provided on the outer surface of the filter element connector, and the O-ring is fitted inside the annular groove.
[0012] A further technical solution includes a limiting structure comprising a plane disposed within the flange, wherein one side of the plane is provided with an inclined surface, and when the flange is disposed below the T-shaped positioning post, the plane abuts against the bottom surface of the horizontal portion of the T-shaped positioning post.
[0013] A further technical solution includes a groove in the plane of the limiting structure, and a glass ball screw is provided in the T-shaped positioning post.
[0014] In a further technical solution, the glass ball screw is provided with a steel ball that can move up and down elastically. When the groove abuts against the steel ball, the steel ball is elastically engaged in the groove.
[0015] In a further technical solution, the T-shaped positioning post is provided with a threaded hole, which is threadedly connected to the glass ball screw.
[0016] The beneficial effects of this utility model are: First, this structure does not require screws to fix the filter element. Through the structural design of flange, bevel, groove, plane, glass ball screw and steel ball, the filter element connector is stably fixed in the hole of the tube sheet. The filter element connector can be fixed and disassembled by rotating the filter element connector, which is very convenient.
[0017] Second, a plane is provided in the flange, forming a stepped shape between the plane and the flange, so that the T-shaped positioning post can be set against the plane, which facilitates the docking of the groove and the glass ball screw.
[0018] Third, the flange is also provided with a bevel, which facilitates the gradual pressing of the steel ball in the glass ball screw into the glass ball screw during the rotation of the filter element connector, making it easier for personnel to rotate the filter element connector clockwise.
[0019] Fourth, a cutout is provided between the flanges. When installing the filter element connector, the cutout is aligned with the T-shaped positioning post. When disassembling the filter element connector, the cutout is also aligned with the T-shaped positioning post, making it easier for personnel to identify the installation position.

Detailed Implementation
[0027] like Figures 1-5 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationship of the filter element is consistent in the up, down, left, right, front, and back directions. This utility model provides a filter element connector that is easy to quickly assemble and disassemble. It includes a filter element connector 11 and a perforated plate 22. The perforated plate 22 is provided with perforated plate holes 21. The filter element connector 11 is inserted into the perforated plate holes 21. The outer surface of the filter element connector 11 is provided with a sealing structure to seal the perforated plate holes 21. The outer surface of the filter element connector 11 is provided with one or more flanges 16. The top of the perforated plate 22 is provided with one or more T-shaped positioning posts 24. After rotation, the flange 16 is snapped into one side of the T-shaped positioning post 24. The flange 16 and the T-shaped positioning post 24 are provided with a limiting structure to snap the flange 16 and the T-shaped positioning post 24 into place.
[0028] Advantageously, when there are two or more flanges 16, a cutout 17 is formed between the flanges 16. The cutout 17 is used to align the T-shaped positioning post 24 so as to avoid interference during insertion. After the filter element connector 11 is inserted into the tube sheet hole 21, the T-shaped positioning post 24 is set in the cutout 17. Then, after rotating the flange 16, the T-shaped positioning post 24 is engaged with the flange 16.
[0029] Advantageously, the vertical cross-sectional shape of the T-shaped positioning post 24 is T-shaped. After the flange 16 abuts against the upper end face of the tube sheet 22, the filter element joint 11 and the flange 16 rotate so that the upper end face of the flange 16 abuts against the bottom surface of the horizontal part of the T-shaped positioning post 24.
[0030] Advantageously, the T-shaped positioning post 24 includes a horizontal disc portion and a vertical cylindrical portion.
[0031] Advantageously, the number of T-shaped positioning posts 24 is the same as the number of flanges 16.
[0032] Advantageously, the sealing structure includes an O-ring 12 fixedly disposed on the outer surface of the filter element connector 11. After the filter element connector 11 is inserted into the perforated plate hole 21, the O-ring 12 abuts against the inner wall of the perforated plate hole 21 to form a sealing structure.
[0033] Advantageously, the number of O-rings 12 can be one, two, or more.
[0034] Advantageously, the outer surface of the filter element connector 11 is provided with an annular groove 33, the O-ring 12 is fitted inside the annular groove 33, the O-ring 12 protrudes from the annular groove 33, and the protruding part of the O-ring 12 abuts against the inner wall of the perforated plate hole 21.
[0035] Advantageously, the limiting structure includes a plane 15 disposed within the flange 16, and a slope 13 is provided on one side of the plane 15. When the flange 16 is disposed under the T-shaped positioning post 24, the plane 15 abuts against the bottom surface of the horizontal part of the T-shaped positioning post 24.
[0036] Advantageously, the limiting structure also includes a groove 14 provided in the plane 15, a glass ball screw 23 provided in the T-shaped positioning post 24, and a steel ball 32 that can move up and down elastically in the glass ball screw 23. When the groove 14 and the steel ball 32 abut against each other, the steel ball 32 is elastically engaged in the groove 14 to prevent the flange 16 from loosening.
[0037] Benefically, the ball screw 23 and the steel ball 32 are existing technologies. The ball screw mainly consists of a screw shank with a spring ball and a nut or threaded hole that mates with it. The screw shank is the main body of the screw and typically has an internal hexagonal, external hexagonal, or other shaped head for easy tightening using tools such as wrenches or screwdrivers. The screw shank may also have threads for mating with the nut or threaded hole. When the screw is tightened, the spring ball is pressed into the threaded hole or nut, providing locking and positioning.
[0038] Advantageously, the T-shaped positioning post 24 is provided with a threaded hole 31, which is threadedly connected to the ball screw 23. By rotating the ball screw 23, the initial height of the steel ball 32 can be adjusted.
[0039] When in use, the filter element connector 11 is inserted into the perforated plate hole 21, and a sealing structure is formed between the O-ring 12 and the inner wall of the perforated plate hole 21.
[0040] After the cutout 17 aligns with the T-shaped positioning post 24, insert the filter element connector 11 into the tube sheet hole 21, so that the lower end face of the flange 16 abuts against the upper end face of the tube sheet 22. Then rotate the filter element connector 11 clockwise. After the flange 16 rotates, the inclined surface 13 passes through the lower end face of the T-shaped positioning post 24, and then the flat surface 15 abuts against the lower end face of the T-shaped positioning post 24. When the steel ball 32 contacts the inclined surface 13 and the flat surface 15, it can retract into the glass ball screw 23. When the groove 14 aligns with the glass ball screw 23, the steel ball 32 and the groove 14 are elastically engaged, and the filter element connector 11 is installed in place.
[0041] When disassembling the filter element connector 11, rotate the filter element connector 11 counterclockwise. When the cutout 17 is aligned with the T-shaped positioning post 24, the filter element connector 11 can be pulled upwards.
[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
