Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, specifically a modular hydraulic oil filter. Background Technology

[0002] In hydraulic equipment, the hydraulic medium plays a role in energy transfer, lubrication of moving components, sealing between moving parts, and heat conduction. However, the hydraulic medium often contains contaminants, including solid particles, water, and air, which cause corrosion, abrasive wear, and cavitation wear to the components of the hydraulic system. Abrasive wear is the most harmful, greatly shortening the service life of hydraulic equipment. Filtration is an effective way to remove solid particulate contaminants from the hydraulic fluid.

[0003] Existing hydraulic oil filters do not allow for direct observation of whether the filter element inside the filter needs replacement, making them inconvenient to use. Furthermore, the overall sealing performance of existing hydraulic oil filters is not good enough, which reduces the sealing effect when assembling the first and second filter frames, thus reducing the filter's filtration efficiency. In addition, existing hydraulic oil filters typically lack positioning assembly capabilities, which means that the oil filter cannot be assembled indefinitely, reducing the filtration speed. They also cannot be used as standalone units on hydraulic equipment, further reducing the filter's assembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a modular hydraulic oil filter to solve the problems mentioned in the background art, such as the poor overall sealing performance of hydraulic oil filters during use and the lack of positioning and assembly functions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular hydraulic oil filter, comprising a first assembly cover, a second assembly cover disposed below the first assembly cover, a first filter frame disposed inside the first assembly cover, a second filter frame disposed inside the second assembly cover, inner plates installed on the inner walls of both the first and second filter frames, slots formed on the surfaces of both the first and second filter frames, the slots being ultrasonically welded together, assembly parts installed on the surfaces of the corner positions of both the first and second assembly covers, assembly holes formed on the surfaces of the assembly parts, positioning assembly mechanisms provided on the inner walls of both the first and second assembly covers, and high-sealing mechanisms provided on the inner walls of both the first and second filter frames.

[0006] Preferably, the surface of the first assembly cover is equipped with a first splicing seat, the surface of the second assembly cover is equipped with a second splicing seat, the surface of the first assembly cover and the second assembly cover are provided with oil inlet and outlet ports, the inner plates are provided with iron wire for heat conduction welding, the iron wire is engaged with the inner wall of the inner plate, and the first filter frame and the second filter frame are welded by heat conduction welding process.

[0007] Preferably, the positioning assembly mechanism consists of a positioning groove, a positioning block, a protrusion, and a groove. The inner wall of the second assembly cover is equipped with positioning blocks for positioning and assembling the first assembly cover and the second assembly cover. The inner wall of the first assembly cover is provided with a positioning groove, and the positioning groove and the surface of the positioning block are engaged with each other.

[0008] Preferably, the surface of the positioning block is provided with protrusions, and the inner wall of the first assembly cover is provided with grooves, and the surface of the protrusions and the inner wall of the grooves are engaged with each other.

[0009] Preferably, the high-sealing mechanism consists of a sealing strip, a first rubber pad, a sealing groove, and a second rubber pad. The inner wall of the second filter frame is equipped with a sealing strip for sealing between the first filter frame and the second filter frame. The inner wall of the first filter frame is provided with a sealing groove. One end of the sealing strip extends into the interior of the sealing groove and fits against the inner wall of the sealing groove.

[0010] Preferably, the inner walls on both sides of the sealing groove are equipped with second rubber pads to improve the sealing effect between the first filter frame and the second filter frame, and the surface of the sealing strip is equipped with a first rubber pad, with the surface of the first rubber pad in contact with the surface of the second rubber pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the modular hydraulic oil filter not only greatly improves the sealing effect when assembling the first filter frame and the second filter frame, making the filter better, but also allows the oil filter to be assembled indefinitely, infinitely increasing the filtration speed. It can also be used as a standalone unit on hydraulic equipment, making the filter assembly efficiency higher, or it can be combined together as a filtration device.

[0012] 1. By incorporating a high-sealing mechanism, when the first filter frame is assembled onto the surface of the second filter frame, the second filter frame causes the sealing strip to engage with the interior of the sealing groove. The combined action of the sealing strip and the sealing groove enhances the sealing performance of the first and second filter frames during assembly. Simultaneously, the first rubber pad on the surface of the sealing strip moves to contact the surface of the second rubber pad. The combined action of the first and second rubber pads ensures a tighter fit between the first and second filter frames during assembly, preventing oil leakage and achieving a high-sealing function for the filter. This significantly improves the sealing effect of the first and second filter frames during assembly, resulting in better filtration performance.

[0013] 2. By incorporating a positioning and assembly mechanism, when the user assembles the first and second assembly covers, the positioning block on the inner wall of the second assembly cover moves into the positioning groove. Under the combined action of the positioning groove and the positioning block, the first and second assembly covers are positioned and assembled, making the docking of the components more precise. At this time, the positioning block drives the protrusion to automatically engage with the groove, thus enabling the first and second assembly covers to be assembled together accurately and efficiently. This achieves the function of positioning and assembling the filter, allowing the oil filter to be assembled indefinitely and its filtration speed to be infinitely amplified. It can also be used as a standalone unit on hydraulic equipment, making the filter assembly efficiency higher. It can also be combined and used as a filtration device, suitable for engineering machinery and hydraulic equipment. Attached Figure Description

[0023] The present invention provides a modular hydraulic oil filter with the following structure: Figure 1 and Figure 2 As shown, the assembly includes a first assembly cover 1, with a second assembly cover 101 located below it. First splicing seats 102 are mounted on the surface of the first assembly cover 1, and second splicing seats 103 are mounted on the surface of the second assembly cover 101. Both the first and second assembly covers 101 have oil inlet / outlet ports 104. A first filter frame 105 is installed inside the first assembly cover 1, and a second filter frame 106 is installed inside the second assembly cover 101. The inner walls of both the first and second filter frames 105 are equipped with... The inner plate 107 has a wire 108 for heat conduction welding between it. The wire 108 is interlocked with the inner wall of the inner plate 107. The first filter frame 105 and the second filter frame 106 are welded by heat conduction welding. The surfaces of the first filter frame 105 and the second filter frame 106 are provided with slots 111. The slots 111 are ultrasonically welded together. The surfaces of the first assembly cover 1 and the second assembly cover 101 are equipped with assembly parts 110. The surfaces of the assembly parts 110 are provided with assembly holes 109.

[0024] Furthermore, such as Figure 4 and Figure 6 As shown, the inner walls of the first assembly cover 1 and the second assembly cover 101 are provided with positioning assembly mechanisms 2. The positioning assembly mechanism 2 consists of positioning grooves 21, positioning blocks 22, protrusions 23 and grooves 24. The inner walls of the second assembly cover 101 are all equipped with positioning blocks 22 for positioning and assembling the first assembly cover 1 and the second assembly cover 101. The inner walls of the first assembly cover 1 are all provided with positioning grooves 21. The surfaces of the positioning grooves 21 and the positioning blocks 22 are engaged with each other. The surfaces of the positioning blocks 22 are provided with protrusions 23. The inner walls of the first assembly cover 1 are provided with grooves 24. The surfaces of the protrusions 23 and the inner walls of the grooves 24 are engaged with each other.

[0025] During implementation, when the user assembles the first assembly cover 1 and the second assembly cover 101, the positioning block 22 on the inner wall of the second assembly cover 101 moves into the positioning groove 21. Under the joint action of the positioning groove 21 and the positioning block 22, the first assembly cover 1 and the second assembly cover 101 are positioned and assembled, making the docking of the assembly parts 110 more precise. At this time, the positioning block 22 drives the protrusion 23 to automatically lock into the groove 24, so that the first assembly cover 1 and the second assembly cover 101 can be assembled together accurately and efficiently to realize the function of filter positioning assembly.

[0026] Furthermore, such as Figure 5 and Figure 7 As shown, both the inner walls of the first filter frame 105 and the second filter frame 106 are provided with a high-sealing mechanism 3. The high-sealing mechanism 3 consists of a sealing strip 31, a first rubber pad 32, a sealing groove 33, and a second rubber pad 34. The inner wall of the second filter frame 106 is equipped with a sealing strip 31 for sealing between the first filter frame 105 and the second filter frame 106. The inner wall of the first filter frame 105 is provided with a sealing groove 33. One end of the sealing strip 31 extends into the interior of the sealing groove 33 and fits against the inner wall of the sealing groove 33. The inner walls on both sides of the sealing groove 33 are equipped with second rubber pads 34 to improve the sealing effect between the first filter frame 105 and the second filter frame 106. The surface of the sealing strip 31 is equipped with a first rubber pad 32, and the surfaces of the first rubber pad 32 and the second rubber pad 34 are in contact.

[0027] In practice, when the first filter frame 105 is assembled on the surface of the second filter frame 106, the second filter frame 106 drives the sealing strip 31 to be engaged inside the sealing groove 33. Under the combined action of the sealing strip 31 and the sealing groove 33, the sealing performance of the first filter frame 105 and the second filter frame 106 during assembly is better. At this time, the first rubber pad 32 on the surface of the sealing strip 31 moves to contact the surface of the second rubber pad 34. Under the combined action of the first rubber pad 32 and the second rubber pad 34, the first filter frame 105 and the second filter frame 106 are more tightly assembled, and there will be no oil leakage, so as to achieve the function of high sealing performance of the filter.

[0028] Working principle: In use, firstly, place the first assembly cover 1 in the designated position. When the first filter frame 105 is assembled on the surface of the second filter frame 106, the second filter frame 106 drives the sealing strip 31 to be engaged inside the sealing groove 33. Under the combined action of the sealing strip 31 and the sealing groove 33, the sealing performance of the first filter frame 105 and the second filter frame 106 during assembly is better. At this time, the first rubber pad 32 on the surface of the sealing strip 31 moves to contact the surface of the second rubber pad 34. Under the combined action of the first rubber pad 32 and the second rubber pad 34, the first filter frame 105 and the second filter frame 106 are more tightly assembled, and there will be no oil leakage, so as to achieve the high sealing performance of the filter. This greatly improves the sealing effect of the first filter frame 105 and the second filter frame 106 during assembly, making the filter effect better.

[0029] Subsequently, the user places the first assembly cover 1 and the second assembly cover 101 on the surfaces of the first filter frame 105 and the second filter frame 106, respectively. The first splicing seat 102 on the surface of the first assembly cover 1 moves to contact the surface of the second splicing seat 103 on the surface of the second assembly cover 101. Under the combined action of the first splicing seat 102 and the second splicing seat 103, the first assembly cover 1 and the second assembly cover 101 are spliced ​​and locked together. The surfaces of the first filter frame 105 and the second filter frame 106 are welded together using ultrasonic technology, and the first filter frame 105 and the second filter frame 106 are joined together using thermal conductivity welding technology. The wire 108 is used to heat-conduct the welding between the first filter frame 105 and the second filter frame 106. Subsequently, the user uses ultrasonic welding technology to weld the groove 111. The groove 111 is used to fill the interior of the first filter frame 105 and the second filter frame 106 with decolorizing sand filter material. With the combined action of the assembly 110 and the assembly hole 109, multiple filters can be assembled together and can be assembled indefinitely to infinitely increase the filtration speed. It can also be used as a standalone unit on hydraulic equipment. Oil enters and exits through the inlet and outlet ports 104 inside the first assembly cover 1 and the second assembly cover 101.

[0030] Subsequently, when the user assembles the first assembly cover 1 and the second assembly cover 101, the positioning block 22 on the inner wall of the second assembly cover 101 moves into the positioning groove 21. Under the joint action of the positioning groove 21 and the positioning block 22, the first assembly cover 1 and the second assembly cover 101 are positioned and assembled, making the docking of the assembly parts 110 more precise. At this time, the positioning block 22 drives the protrusion 23 to automatically lock into the groove 24, so that the first assembly cover 1 and the second assembly cover 101 can be assembled together accurately and efficiently to realize the function of filter positioning assembly. This allows the oil filter to be assembled infinitely and the filtration speed to be infinitely amplified when the filter is used. It can also be used as a standalone unit on hydraulic equipment, making the filter assembly efficiency higher and finally completing the use of the modular hydraulic oil filter.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
