Description

Technical Field

[0001] This utility model relates to filtration structures, and in particular to a straight-through T-type filter pleated filter element. Background Technology

[0002] A ship-shaped filter element is an oil filter element that resembles the shape of a ship's hull. It is also often called a quick-opening filter element. It is easy to install and suitable for situations where it is inconvenient to replace and maintain traditional filter elements, especially in scenarios involving high-viscosity oils or requiring frequent replacement.

[0003] Therefore, boat-shaped filter elements typically use a more traditional mesh structure as the filtration unit, which has high flow capacity and is easy to clean, but has low filtration accuracy and is usually used in the oil suction port of hydraulic pumps. In order to improve the filtration accuracy of traditional mesh filter elements, the design considers applying pleated filter elements inside boat-shaped filter elements. Traditional pleated filter elements are usually formed by folding stainless steel fiber sintered felt. If they are fixed by welding, the boat-shaped filter elements cannot be reused. Therefore, a new structure is needed to combine pleated filter elements with boat-shaped filter elements. Utility Model Content

[0004] The purpose of this invention is to provide a straight-through T-type pleated filter element, which has the advantages of convenient installation and disassembly, improved filtration accuracy, and good impact resistance.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a straight-through T-type filter pleated filter element, comprising a filter element body, the filter element body comprising a sealing end, a sliding guide plate, a circular hole concave arc plate and a pleated metal mesh, the sealing end being disposed at the front end of the sliding guide plate, a filter window being disposed at the center of the sliding guide plate, the circular hole concave arc plate being disposed at the bottom of the filter window, the circular hole concave arc plate being bent downward in the height direction of the sliding guide plate, a filter plate being disposed at one end of the circular hole concave arc plate facing the sealing end, a sealing plate being disposed at the other end of the circular hole concave arc plate, a reinforcing frame being disposed at the bottom of the circular hole concave arc plate, sheet metal connecting hooks being disposed on both sides of the sliding guide plate in the width direction, and connecting holes cooperating with sheet metal connecting hooks being disposed at both ends of the pleated metal mesh in the width direction, the pleated metal mesh covering the top of the filter window, the folding direction of the pleated metal mesh allowing the pleated metal mesh to deform into the circular hole concave arc plate.

[0006] Preferably, the sheet metal connecting hook is formed by sheet metal stamping and bending, and the sliding guide plate is provided with punching holes for stamping the sheet metal connecting hook. The projected area of ​​the punching holes is larger than that of the sheet metal connecting hook, and the punching holes are respectively provided on both sides of the width direction of the filter window.

[0007] By adopting the above technical solution, the manufacturing cost is lower, and the punching hole allows the portion of the folded metal mesh to enter below the sheet metal connecting hook.

[0008] Preferably, the sheet metal connecting hook includes an inclined section and a horizontal section, one end of the inclined section is connected to a punching hole, the other end of the inclined section is connected to the other end of the horizontal section, and the horizontal section is located directly above the punching hole.

[0009] By adopting the above technical solution, the inclined section creates a gap between the horizontal section and the sliding guide plate. The gap allows the folded metal mesh to enter from both sides in the width direction, which plays a guiding role during installation, making installation more convenient and preventing loosening.

[0010] Preferably, the folded metal mesh has connecting sections on both sides in the width direction, the connecting holes are located in the connecting sections, the connecting sections are located below the horizontal sections, and the ends of the horizontal sections are bent into the punching holes.

[0011] By adopting the above technical solution, the connecting section is set horizontally, which facilitates fixing between the horizontal section and the sliding guide plate. At the same time, the end of the horizontal section is bent into the punch hole, forming a curved structure, which avoids the sharp connecting section being exposed to the outside, and avoids rubbing between the filter element and the inner cavity of the shell during the installation process, thus facilitating installation.

[0012] Preferably, the folded metal mesh has a wavy folded section between adjacent connecting sections. The wavy folded section can unfold and close along the width direction of the folded metal mesh. The length of the wavy folded section is less than the length of the filter window. The wavy folded section deforms downward and fits against the upper surface of the concave arc plate with the circular hole.

[0013] By adopting the above technical solution, the wave-folded section increases the filtration area during the filtration process, improving the filtration effect within a limited space. At the same time, during the impact resistance process, it deforms downwards, allowing it to fit against the surface of the arc-shaped plate and accommodate filtered impurities.

[0014] Preferably, the longitudinal section of the concave arc plate with the circular hole is semi-circular, the filter plate and the sealing plate are semi-circular, and the filter plate and the sealing plate are welded to the concave arc plate with the circular hole and the filter window in the circumferential direction.

[0015] By adopting the above technical solution, the impact resistance is better, and the fluid pressure can be distributed to the sliding guide plates on both sides, thereby improving the overall pressure resistance.

[0016] Preferably, the concave arc-shaped plate with the circular hole is provided with filter holes, the filter holes are circular and distributed inside the filter plate.

[0017] By adopting the above technical solution, the filter holes play a filtering role.

[0018] Preferably, the reinforcing frame includes C-shaped rings, with the two ends of the C-shaped rings in the length direction connected to the bottom of the two ends of the sliding guide plate in the width direction. The C-shaped rings are evenly distributed along the length direction of the sliding guide plate, and the inner side of the C-shaped rings is connected to the bottom of the concave arc plate with the circular hole.

[0019] By adopting the above technical solution, the structural strength can be improved within the space, and the deformation at that location can be reduced.

[0020] Preferably, a guide mounting plate is provided at the bottom of the concave arc plate with the circular hole, and the guide mounting plate passes through the C-shaped ring and is connected to the bottom of the concave arc plate with the circular hole.

[0021] By adopting the above technical solution, the filter element can be guided during installation, avoiding positional shifts and preventing rotation during use.

[0022] In summary, during use, the sealing end, the concave arc plate with the circular hole, and the sliding guide plate form the boat-shaped filter element structure in the prior art. By providing sheet metal connecting hooks on both sides of the sliding guide plate in the width direction and connecting holes on the folded metal mesh, installation and disassembly are convenient. Furthermore, after the sheet metal connecting hooks are hooked into the connecting holes, the folded metal mesh can deform upwards towards the concave arc plate with the circular hole. That is, during the filtration process, after the fluid impacts the folded metal mesh, it unfolds and deforms towards the position of the concave arc plate with the circular hole, achieving dual filtration through the concave arc plate with the circular hole and the folded metal mesh. Simultaneously, the concave arc plate with the circular hole provides the first layer of support for the folded metal mesh; at the same time, the reinforced frame provides the second layer of support for the concave arc plate with the circular hole, improving its impact resistance.

At the same time, the filter holes 31 are evenly distributed on the circular hole concave arc plate 3. The diameter of the filter holes 31 is larger than the diameter of the filter holes in the pleated metal mesh 4 to avoid reducing the filtration rate.

[0027] like Figure 2 As shown, a filter plate 32 is provided at one end of the concave arc plate 3 with a circular hole facing the sealing end 1, and a sealing plate 33 is provided at the other end of the concave arc plate 3 with a circular hole.
