Description

Technical Field

[0001] The invention relates to the technical field of oil filtration, in particular to a new filter for filtering mineral oil. Background Art

[0002] After a period of use, the mineral oil in the equipment will be contaminated and contain some mechanical impurities. If not handled, it will cause the equipment using the mineral oil to malfunction. Therefore, after the mineral oil has been used for a period of time, it needs to be filtered with a filter to remove the impurities in the mineral oil and restore the cleanliness of the mineral oil.

[0003] Existing filters often suffer from poor mineral oil filtration due to loose filter element seals. Furthermore, improper oil inlet design in existing filters causes high-speed, high-pressure mineral oil to directly impact the filter element, shortening its lifespan. Utility Model Content

[0004] The utility model aims to solve the problem that the service life of the filter element is shortened due to improper oil port design, and solves the problem that the mineral oil filtering effect is poor due to loose fixing and sealing of the filter element.

[0005] In order to solve the above problems, this application is implemented through the following technical solutions:

[0006] A new filter for filtering mineral oil includes a filter cartridge. The inner wall of the bottom of the filter cartridge is fixedly sealed and connected to the bottom of the filter element through a first sealing ring, and the top of the filter element is fixedly sealed and connected to the filter element pressure plate through a second sealing ring. A screw is provided inside the filter element pressure plate to connect to the top of an oil distributor. The oil outlet of the oil distributor is connected to the bottom side wall of the filter cartridge. A flange is provided on the top of the filter cartridge, and the flange is fit and fixedly connected to a cover plate.

[0007] The cover plate is equipped with an exhaust valve and a pressure gauge.

[0008] The top side wall of the filter cartridge is fixedly and sealedly connected to the cover plate through a third sealing ring.

[0009] The bottom side wall of the filter cartridge is provided with a sewage outlet.

[0010] The bottom wall of the filter cartridge is provided with an oil outlet.

[0011] The oil outlet distributor is arranged inside the filter element, and a plurality of oil outlet holes are arranged on the inner wall of the oil outlet distributor.

[0012] The side wall of the filter cartridge is provided with an oil inlet.

[0013] A buffer plate is provided inside the oil inlet of the oil inlet.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The purpose of this new model is to manufacture a new type of filter for filtering mineral oil, which has the characteristics of easy disassembly, simple production, stable filtration and long service life.

[0016] 2. This new model slows down the direct impact of high-speed and high-pressure mineral oil entering the filter by setting an oil inlet and a buffer plate. By setting a sealing ring in the filter element and setting a sealing ring and a top flange inside the filter element, the filter can filter effectively and stably for a long time, ensure the air tightness of the filter device, and avoid the problem of filter element damage. At the same time, a pressure gauge is set to judge whether the filter element is blocked, which is convenient for cleaning and replacement of the filter element. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example 1

[0023] See also Figure 1 and Figure 2A new type of filter for filtering mineral oil includes a filter cartridge 7, an oil inlet 6 is provided on the side wall of the filter cartridge 7, the bottom inner wall of the filter cartridge 7 is fixedly sealed and connected to the bottom of the filter element 3 through a first sealing ring 2, and the top of the filter element 3 is fixedly sealed and connected to the filter element pressing plate 10 through a second sealing ring 9. A screw is provided inside the filter element pressing plate 10 to connect the top of the oil distributor 5, and the oil outlet 1 of the oil distributor 5 is connected to the bottom side wall of the filter cartridge 7. A flange 8 is provided on the top of the filter cartridge 7, and the flange 8 is fitly fixedly connected to the cover plate 12.

[0024] The cover plate 12 is equipped with an exhaust valve 13 and a pressure gauge 14.

[0025] The top side wall of the filter cartridge 7 is fixedly and sealedly connected to the cover plate 12 via a third sealing ring 11 .

[0026] A sewage outlet 15 is provided on the bottom side wall of the filter cartridge 7 .

[0027] An oil outlet 1 is provided on the bottom wall of the filter cartridge 7 .

[0028] The oil distributor 5 is installed inside the filter element 3 , and a plurality of oil outlet holes are provided on the inner wall of the oil distributor 5 , which are used to discharge the filtered mineral oil through the oil outlet 1 .

[0029] An oil inlet 6 is provided on the side wall of the filter cartridge 7 , and a buffer plate 4 is provided on the inner side of the oil inlet of the oil inlet 6 .

[0030] Preferably, the buffer plate 4 is used to block and buffer the oil at the oil inlet 6. Preferably, the oil outlet distributor 5 is used to fix the oil outlet of the filter element. Preferably, the first sealing ring 2 is used to seal the contact between the bottom of the filter element 3 and the bottom inner wall of the filter cartridge 7. Preferably, the second sealing ring 9 is used to seal the contact between the top of the filter element 3 and the filter element pressure plate 10.

[0031] like Figure 1 As shown, a new filter for filtering mineral oil, the screw on the lower side of the filter element pressing plate 10 is threadedly connected to the internal threaded hole at the top of the oil distributor 5, pressing the filter element 3 into the filter cartridge 7; the cover plate 12, the filter cartridge 7 and the third sealing ring 11 form a closed filter chamber for the mineral oil;

[0032] Mineral oil enters the filter cartridge 7 from the oil inlet 6, passes through the oil-blocking buffer plate 4, and changes direction to enter the outer side of the filter element 3. The high-pressure oil does not directly impact the filter element 3, but is evenly filtered through the filter element 3. Impurities are blocked on the outer surface of the filter element 3, and only clean oil enters the inner cavity of the filter element 3. The clean mineral oil obtained by filtration enters the inner wall of the oil distributor 5 through the multiple oil outlet holes densely distributed on the oil distributor 5, and is then discharged from the equipment through the oil outlet 1. Impurities are discharged through the drain port 15 on the filter cartridge 7.

[0033] When mineral oil enters the inner cavity of the filter cartridge 7, the gas in the inner cavity of the filter cartridge 7 is discharged through the exhaust valve 13 on the cover plate 12 so that the oil fills the inner cavity of the filter cartridge 7; the pressure gauge 14 detects the pressure in the inner cavity of the filter cartridge 7. When the pressure is greater than 0.5Mpa, the filter element 3 needs to be replaced.
