Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology, and in particular to a filter element structure for an oil return filter. Background Technology
[0002] The filter element structure of the return oil filter is mainly used to filter impurities, dirt, and particulate matter in the oil, ensuring the cleanliness of the oil and the normal operation of the equipment. Through its specific pore size and material, the filter element effectively intercepts contaminants in the oil, preventing them from entering the mechanical system, reducing wear and failure risks, and extending equipment life. At the same time, the filter element can also maintain the fluidity and pressure stability of the oil, ensuring the efficient operation of the hydraulic and lubrication systems. Regularly replacing the filter element can maintain the cleanliness of the system and reduce maintenance costs.
[0003] However, the existing filter element structure of the return oil filter lacks an effective impurity collection mechanism during use. Impurities are randomly distributed inside, and as filtration proceeds, the material is gradually filled with impurities, leading to pore blockage of the filter medium, reduced filtration area, and increased fluid resistance. This not only significantly reduces the collection effect but also causes a sharp drop in filtration efficiency, seriously affecting the overall performance and service life of the equipment.
[0004] Therefore, this application provides a filter element structure for a return oil filter to meet the requirements. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a filter element structure for a return oil filter.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a filter element structure for an oil return filter, comprising:
[0007] A bottom support plate and a support rod placed on top of the bottom support plate, with a top support plate installed on top of the support rod;
[0008] A bottom fixing assembly is placed on top of a bottom support plate. The bottom fixing assembly includes a first lifting ring fixed to the top of the bottom support plate. Each of the first lifting rings is provided with a first clamping plate. Each of the first clamping plates is provided with a first fabric clamping rod. Each of the inner sides of the first lifting rings is provided with a connecting block. A connecting rod is provided between the connecting blocks. A support ring is provided in the middle of the connecting rod.
[0009] A top fixing assembly is placed at the bottom of a top support plate. The top fixing assembly includes a second lifting ring fixed to the bottom of the top support plate. A second clamping plate is provided on each of the second lifting rings, and a second fabric clamping rod is provided on each of the second clamping plates.
[0010] In a preferred embodiment, an expansion plate is provided on the outer side of the second lifting ring, and the expansion plate is slidably connected to the outer telescopic rod.
[0011] The beneficial effect of adopting the above-mentioned further solution is that: an expansion plate is provided on the outer side of the second lifting ring, which is slidably connected to the telescopic rod. When the screw rotates and the bottom component rises, the telescopic rod pushes the second lifting ring to move in the opposite direction through the expansion plate, thereby achieving the flipping of the filter cloth.
[0012] In a preferred embodiment, a lead screw is provided on the support ring, and a motor is provided on the top of the lead screw.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the motor drives the lead screw to rotate, which drives the support ring to rise and fall, thereby adjusting the bottom fixing component and realizing the flipping of the filter cloth.
[0014] In a preferred embodiment, the top of the top support plate has a slot, and a box cover is provided on the top support plate through the slot. A hinge is provided between the top support plate and the box cover.
[0015] The beneficial effects of adopting the above-mentioned further solution are: the top support plate has a slot at the top and is connected to the box cover by a hinge. When the filter cloth is flipped over, the box cover can be opened manually to wash the filter cloth. The internal particles generated during washing can be smoothly discharged from the box cover along the slot.
[0016] In a preferred embodiment, the first clamping plate is directly provided with a rotating shaft near the first lifting ring.
[0017] The beneficial effect of adopting the above-mentioned further solution is that a rotating shaft is provided near the first lifting ring on the first clamping plate. When the filter cloth is flipped, the rotating shaft makes the first clamping plate rotate flexibly, thus avoiding cloth damage.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] 1. The first lifting ring is fixed on the bottom support plate. The first clamping plate and the first cloth clamping rod on the first lifting ring are used to firmly clamp one end of the filter cloth. The connecting rod connected to the inner connecting block has a support ring in the middle. When working, the support ring moves up and down along the connecting rod under the power of the motor, which drives the first lifting ring to rise and fall, thereby adjusting the flipping of the filter cloth, so as to achieve the effect of flipping the filter cloth and collecting the residue on the filter cloth into the equipment.
[0020] 2. The top fixing component is installed at the bottom of the top support plate, and the second lifting ring is firmly fixed here. The second clamping plate and the second cloth clamping rod on it work together to accurately clamp the other end of the filter cloth. When the bottom fixing component is driven by the motor, the filter cloth connects the two, which will cause the second lifting ring to drive the second clamping plate to move in the opposite direction. This will help the bottom fixing component to flip the filter cloth, transfer the residue on the outside of the filter cloth to the inside, and facilitate collection into the equipment, ensuring a stable and long-lasting filtration effect.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a filter element structure for a return oil filter, comprising: a filter element structure for a return oil filter, comprising:
[0033] The bottom support plate 1 and the support rod 6 placed on top of the bottom support plate 1, with a top support plate 2 provided on the top of the support rod 6;
[0034] The bottom fixing component 5 is placed on top of the bottom support plate 1. The bottom fixing component 5 includes a first lifting ring 51 fixed on the top of the bottom support plate 1. Each first lifting ring 51 is provided with a first clamping plate 52. Each first clamping plate 52 is provided with a first cloth clamping rod 53. Each inner side of the first lifting ring 51 is provided with a connecting block 54. A connecting rod 55 is provided between the connecting blocks 54. A support ring 56 is provided in the middle of the connecting rod 55. The first lifting ring 51 is fixed on the bottom support plate 1. The first clamping plate 52 and the first cloth clamping rod 53 on the first lifting ring 51 are used to firmly clamp one end of the filter cloth 11. The connecting rod 55 connected to the inner connecting block 54 has a support ring 56 in the middle. When working, the support ring 56 moves up and down along the connecting rod 55 under the power drive of the motor 9, which drives the first lifting ring 51 to rise and fall, thereby adjusting the flipping of the filter cloth 11, so as to achieve the effect of flipping the filter cloth 11 and collecting the residue on the filter cloth 11 into the equipment.
[0035] The top fixing component 7 is located at the bottom of the top support plate 2. The top fixing component 7 includes a second lifting ring 71 fixed at the bottom of the top support plate 2. The second lifting ring 71 is provided with a second clamping plate 72, and the second clamping plate 72 is provided with a second cloth clamping rod 73. The top fixing component 7 is installed at the bottom of the top support plate 2, and the second lifting ring 71 is firmly fixed here. The second clamping plate 72 and the second cloth clamping rod 73 work together to accurately clamp the other end of the filter cloth 11. When the bottom fixing component 5 is driven by the motor 9, since the filter cloth 11 connects the two, the second lifting ring 71 will drive the second clamping plate 72 to move in the opposite direction, thereby cooperating with the bottom fixing component 5 to realize the flipping of the filter cloth 11, transferring the residue on the outside of the filter cloth 11 to the inside, making it easier to collect into the equipment and ensuring a stable and long-lasting filtration effect.
[0036] Furthermore, such as Figure 1 - Figure 4 As shown: An expansion plate 74 is provided on the outer side of the second lifting ring 71. The expansion plate 74 is slidably connected to the telescopic rod 12 on the outer side. When the screw 8 rotates to raise the bottom component, the telescopic rod 12 pushes the second lifting ring 71 to move in the opposite direction through the expansion plate 74, thus cooperating to achieve the flipping of the filter cloth 11.
[0037] The above solutions also have the problem of fabric flipping, such as... Figure 1 - Figure 4 As shown: In this scheme, a lead screw 8 is provided on the support ring 56, and a motor 9 is provided on the top of the lead screw 8. The motor 9 drives the lead screw 8 to rotate, thereby driving the support ring 56 to rise and fall, thereby adjusting the bottom fixing component 5 and realizing the flipping of the filter cloth 11.
[0038] Working principle: such as Figure 1 - Figure 4 As shown, in the bottom fixing assembly 5, the first lifting ring 51 is fixed to the bottom support plate 1, and its first clamping plate 52 and the first cloth clamping rod 53 clamp one end of the filter cloth 11. The connecting block 54 connects the connecting rod 55 and the middle support ring 56. The motor 9 is fixed through the connecting plate 10. When the motor 9 drives the lead screw 8 to rotate, the support ring 56 rises and falls along the connecting rod 55, driving the first lifting ring 51 to move, adjusting the filter cloth 11 to flip, so that the outer residue is transferred to the inner collection. The top fixing assembly 7 is located at the bottom of the top support plate 2. The second clamping plate 72 on the second lifting ring 71 and the second cloth clamping rod 73 clamp the other end of the filter cloth 11. When the bottom assembly moves, because the filter cloth 11 is connected, the second lifting ring 51... The lowering ring 71 drives related components to move in the opposite direction to cooperate in flipping. The outer expansion plate 74 of the second lifting ring 71 is slidably connected to the telescopic rod 12. When the screw 8 rotates and the bottom component rises, the telescopic rod 12 pushes the second lifting ring 71 to move in the opposite direction to assist in flipping. The top support plate 2 has a groove at the top and is connected to the box cover 3 by the hinge 4. After the filter cloth 11 flips, the box cover 3 can be opened manually to rinse the filter cloth 11. The internal particles are discharged from the box cover 3 through the groove. The first clamping plate 52 is close to the rotating shaft 57 of the first lifting ring 51. When the filter cloth 11 flips, the first clamping plate 52 can rotate flexibly to prevent the filter cloth 11 from being damaged. These components cooperate with each other to ensure the stable and efficient filtration performance and convenient maintenance of the return oil filter element.
[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
