Description

Technical Field

[0001] The utility model relates to the technical field of oil filters, in particular to an oil filter pressurizing device. Background Art

[0002] The oil filter pressurizing device is a device used to filter impurities in hydraulic oil. Its structure is mainly composed of a housing and a filter element. The main function of the oil filter pressurizing device is to ensure the cleanliness and stable operation of the hydraulic system, because the particulate impurities in the oil will cause wear to the hydraulic components and affect the performance of the system. According to different filtering requirements, oil filters can be divided into multiple accuracy levels, including coarse oil filters, ordinary oil filters, fine oil filters and special fine oil filters. These oil filters can be based on their design, such as mesh type, wire gap type, paper core type and sintered type, etc. Different forms meet the specific filtering accuracy requirements of various hydraulic systems.

[0003] However, it still has the following disadvantages in actual use:

[0004] In the existing oil filter, the internal filter element will be clogged during long-term filtration. The clogged filter element will restrict the flow of oil, resulting in a decrease in the working efficiency of the hydraulic system, which may manifest as slow operation or sluggish response of the equipment. When the filter element cannot effectively filter impurities, these impurities may enter the system, aggravating the wear of the relative motion surface and may even cause the slide valve to stick or the throttling orifice to be clogged. In the long run, this will greatly reduce the life and reliability of the equipment.

[0005] Therefore, a new oil filter pressurizing device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an oil filter pressurizing device to solve the problem raised in the above background technology that the internal filter element of the existing oil filter will be blocked during long-term filtration. The blocked filter element will restrict the flow of oil, resulting in a decrease in the working efficiency of the hydraulic system, which may manifest as slow operation or slow response of the equipment. When the filter element cannot effectively filter impurities, these impurities may enter the system, aggravate the wear of the relative motion surface, and may even cause the slide valve to become stuck or the throttling orifice to become blocked. In the long run, this will greatly reduce the life and reliability of the equipment.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] See also Figure 1-Figure 4 As shown, this embodiment is an oil filter pressurizing device, comprising:

[0040] A main body component, the main body component includes an oil filter housing 11;

[0041] The main assembly also includes a filter element 12, a vacuum pump 13, an oil inlet 14, and an oil return port 15;

[0042] A filter element 12 is installed inside the oil filter housing 11, a vacuum pump 13 is installed above the oil filter housing 11, an oil inlet 14 is connected to one side of the oil filter housing 11, and an oil return port 15 is connected to the other side of the upper end of the oil filter housing 11;

[0043] The oil filter housing 11 is used to accommodate and protect the core component filter element 12 inside. The vacuum pump 13 is mainly used to create a negative pressure environment to assist the filtering process. The oil inlet 14 is the channel for the oil to be filtered to enter the filter. The oil return port 15 is the oil cleaned by the filter element 12 and returned to the system or the oil tank through here.

[0044] The anti-blocking component includes a connecting pipe 21, a connecting block 22, a first connecting rod 23, a second connecting rod 24, and a semi-ring plate 25;

[0045] A connecting pipe 21 is passed through the oil filter housing 11. A connecting block 22 is fixed to the upper surface of the connecting pipe 21. A first connecting rod 23 is movably connected to one side of the connecting block 22. A second connecting rod 24 is movably connected to the lower end of the first connecting rod 23. A semi-ring plate 25 is connected to the lower end of the second connecting rod 24.

[0046] The connecting pipe 21 penetrates the inside of the oil filter housing 11 and is a component for connecting and transmitting force;

[0047] The anti-blocking assembly also includes a connecting groove 26, a blocking block 27, a spring 28, and a square groove 29;

[0048] A connecting groove 26 is provided in the middle of the upper end of the semi-ring plate 25, a blocking block 27 is fixed to the outer side wall of the semi-ring plate 25, a spring 28 penetrates the outer surface of the connecting pipe 21, and a square groove 29 is provided at the lower end of the connecting pipe 21;

[0049] The spring 28 is sleeved outside the connecting pipe 21 to provide necessary elastic force to help achieve the anti-blocking function, and the lower end of the spring 28 can be inside the oil filter housing 11;

[0050] When the filter element 12 is clogged, the impurities accumulated on the filter holes can be pushed away or removed by the blocking block 27 through the transmission of the mechanical connecting rod, thereby restoring the permeability of the filter element 12 and avoiding the reduction of efficiency or damage of the hydraulic system caused by the blockage of the filter element 12;

[0051] Working principle:

[0052] When the filter element 12 is clogged;

[0053] First, the staff can directly hold the lower end of the connecting pipe 21 and pull it downward.

[0054] At this time, the spring 28 is compressed, driving the connecting block 22 to move downward, and at the same time the first connecting rod 23 is opened outward and placed horizontally.

[0055] The second connecting rod 24 is driven to move to both sides, and the semi-ring plate 25 is driven to move outward, so that the blocking block 27 is stuck into the filter hole of the filter element 12, and the blocked particles are pushed out.

[0056] At the same time, after the staff releases their hands, the spring 28 recovers its deformation, drives the connecting block 22 to move upward, and drives the semi-ring plate 25 to move inward, so as to remove the blocked impurities, thereby avoiding the need to replace the filter element 12 in advance due to long-term accumulation.

[0057] This step saves costs, ensures the fluidity and cleanliness of the oil, and prevents problems such as insufficient pump oil suction, slow component movement, or non-movement of the oil cylinder due to blockage of the filter element 12.

[0058] See also Figure 5 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0059] Sealing components;

[0060] The sealing assembly includes a fixing ring 31, a thread groove 32, a connecting plate 33, and a clamping column 34;

[0061] A fixing ring 31 is fixed to the middle of the lower surface of the oil filter housing 11, a thread groove 32 is provided inside the fixing ring 31, a connecting plate 33 is threadedly connected inside the fixing ring 31, and a clamping column 34 is fixed inside the connecting plate 33;

[0062] The function of the fixing ring 31 is to provide a fixing point for connecting other sealing components, and the function of the thread groove 32 is to cooperate with the thread on the connecting plate 33 to achieve a tight connection between the connecting plate 33 and the fixing ring 31;

[0063] Working principle:

[0064] After cleaning the filter element 12, in order to prevent the connecting pipe 21 from leaking oil;

[0065] At this time, the staff only needs to rotate the connecting plate 33 into the interior of the fixing ring 31.

[0066] And the clamping column 34 is inserted into the interior of the connecting pipe 21,

[0067] This step can ensure the working efficiency of the hydraulic system and the stability of energy transmission, and can reduce maintenance costs and time.
