Description

Technical Field

[0001] The utility model belongs to the technical field of oil filter elements, in particular to an oil filter element for a hydraulic oil pipeline. Background Art

[0002] The hydraulic oil filter is an indispensable key filter component in the hydraulic system. Its main function is to effectively filter out various solid pollutants that invade from the outside or are generated inside the system during operation, including metal grinding chips, dust particles and other mechanical impurities. As a protective barrier for the hydraulic system, the filter element significantly reduces the contamination of the hydraulic oil through precision filtration, thereby protecting the hydraulic components from abnormal wear and ensuring the reliability and stability of the system operation. At the same time, regular maintenance and replacement of the hydraulic oil filter element can maintain the performance indicators of the hydraulic oil, extend the service life of the hydraulic oil, and thus improve the operating efficiency and service life of the entire hydraulic system. However, it still has the following disadvantages in actual use:

[0003] 1. When the hydraulic oil filter is working, the hydraulic oil flows into the outside of the filter element, is filtered by the filter element, and is discharged into the hydraulic system through the output pipeline. When the filtering efficiency of the traditional hydraulic oil filter element decreases, the filter element is usually replaced directly, which is difficult to clean and requires frequent replacement, resulting in high cost of use;

[0004] 2. Secondly, when the filter element is in use, surface filtration is performed to achieve a larger filtration area. Impurities in the hydraulic oil will be deposited on the surface of the filter element and in the filter. After a certain period of use, more impurity precipitation will remain in the filter. After the impurities are precipitated, the staff needs to clean them manually, which is inconvenient to operate. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses an oil filter element for a hydraulic oil pipeline, comprising a mounting plate, a filter element main body, a fixing sleeve and a flushing assembly, wherein a filter element main body is fixed at the top center of the mounting plate, a scraper ring is sleeved on the peripheral side of the filter element main body, a fixing sleeve is fixed on the peripheral side of the scraper ring, an inner wall of the scraper ring is sleeved on the peripheral side of the filter element main body, a flushing assembly is arranged in the filter element main body, the flushing assembly comprises a flushing shell and a spray hole, and the spray holes are evenly opened on the peripheral side of the flushing shell. When working, the installation of the filter element main body is provided through the mounting plate, and when the filter element main body is working, the hydraulic oil entering the filter is filtered, the scraper ring is connected thereto through the fixing sleeve, and the scraper ring rises when the fixing sleeve rises, so as to scrape off the impurities filtered out on the surface of the filter element main body, and guide the impurities to flow into the fixing sleeve through the scraper ring, and after the hydraulic oil through flushing enters the flushing shell, it is evenly sprayed into the filter element main body through the spray hole to flush the filter element main body.

[0008] Furthermore, an output pipe is fixed vertically through the center of the installation disk, and the top end of the output pipe is connected to the inside of the filter element body. When the installation disk is working, the hydraulic oil filtered in the filter element body is discharged through the output pipe.

[0009] Furthermore, a sealing ring is fixed to the bottom of the mounting plate outside the output pipe, and screws are fixed to the bottom of the output pipe outside the sealing ring in a circular array. When the output pipe is working, the sealing ring seals the gap between the mounting plate and the output pipe and the filter.

[0010] Furthermore, the vertical section of the scraper ring is a right triangle, the inner bottom of the fixing sleeve is fixed with fixing rods in a ring array, the tops of all the fixing rods are commonly fixed with a connecting ring, and the fixing sleeve is connected to the connecting ring through the fixing rods.

[0011] Furthermore, the flushing assembly also includes a flushing pipe, and the top center of the flushing shell is fixedly connected with the flushing pipe. The flushing shell is arranged in the filter element body. When the flushing assembly is working, the hydraulic oil for flushing is transported to the flushing shell through the flushing pipe.

[0012] Furthermore, the bottom end of the filter element body is open, a fixing hole is provided in the center of the top cover of the filter element body, the flushing pipe is passed through and fixed in the fixing hole, and the filter element body fixes the flushing pipe through the fixing hole.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the traditional hydraulic oil filter is difficult to clean and needs to be replaced frequently by arranging a mounting plate, a filter element body and a flushing assembly. The hydraulic oil is transported to the flushing shell through a flushing pipe. After the flushing hydraulic oil is evenly sprayed onto the inner wall of the filter element body through the flushing shell through the spray hole, the flushing hydraulic oil passes through the filter element body to flush out the impurities retained in the filter element body and flush the filter element body, so that the hydraulic oil filter element can be easily flushed, the replacement cycle is longer, and the use cost is lower.

[0015] 2. The utility model solves the problem that the traditional hydraulic oil filter element has only filtering function and the impurities deposited in the filter are inconvenient to clean by arranging the mounting plate, the filter element main body and the fixing sleeve. During operation, the deposited impurities generated by the hydraulic oil filtration are deposited in the fixing sleeve. When working for a long time and a large number of impurities are deposited on the surface of the filter element main body, the connecting ring is pulled and connected with the fixing sleeve through the fixing rod, so as to drive the fixing sleeve and the scraping ring to rise on the outside of the filter element main body. After the scraping ring scrapes on the surface of the filter element main body, the impurities are deposited on the bottom of the fixing sleeve. After the scraping ring leaves the surface of the filter element main body, it is arranged on the outside of the flushing pipe. After cleaning the impurities deposited in the fixing sleeve, the impurities deposited on the outside of the filter element main body are cleaned up. Then the connecting ring is held and the scraping ring is put on the outside of the filter element main body. The connecting ring is pressed down until the bottom end of the fixing sleeve is supported and arranged on the top of the mounting plate. The cleaning of the deposited impurities filtered out by the filter element is completed, so that the impurities deposited in the filter and the impurities filtered out on the surface of the filter element and easy to scrape off are conveniently scraped off and cleaned up.

Specific embodiment 1

[0027] See also Figure 1-4 The utility model is an oil filter element for a hydraulic oil pipeline, comprising a mounting plate 1, a filter element body 2, a fixing sleeve 3 and a flushing assembly 4. The filter element body 2 is fixed at the top center of the mounting plate 1. When the mounting plate 1 is working, the filter element body 2 is installed thereon in cooperation, and the oil is filtered through the filter element body 2. A scraping ring 301 is provided on the peripheral side of the filter element body 2. When scraping between the scraping ring 301 and the filter element body 2, impurities retained on the surface of the filter element body 2 are scraped off. A fixing sleeve 3 is fixed on the peripheral side of the scraping ring 301. Impurities on the surface of the filter element are scraped off by the scraping ring 301. The impurities deposited in the oil fall into the fixed sleeve 3, and the deposited impurities are caught by the fixed sleeve 3. The inner wall of the scraper ring 301 is sleeved on the peripheral side of the filter element main body 2. A flushing component 4 is arranged in the filter element main body 2. When the flushing component 4 works, the flushing oil is input into the filter element main body 2, so that the impurities filtered in the filter element main body 2 are flushed away. The flushing component 4 includes a flushing shell 401 and an ejection hole 402. The ejection holes 402 are evenly opened on the peripheral side of the flushing shell 401. The flushing oil entering the flushing shell 401 is ejected through the ejection hole 402.

[0028] Specifically, an output pipe 101 is fixed vertically through the center of the mounting disk 1. After the mounting disk 1 is installed in the filter, the bottom end of the output pipe 101 is connected to the device for outputting filtered hydraulic oil, and the top end of the output pipe 101 is connected to the inside of the filter element body 2. The mounting disk 1 discharges the oil in the filter element body 2 through the output pipe 101.

[0029] Furthermore, a sealing ring 102 is fixed to the bottom end of the mounting disk 1 outside the output pipe 101, and a screw 103 is fixed to the bottom end of the output pipe 101 outside the sealing ring 102 in a ring array. When the output pipe 101 is working, the sealing ring 102 cooperates with the mounting disk 1 to close the mounting gap between the mounting disk 1 and the mounting device, and the screw 103 is inserted into the corresponding position on the filter device and then extended out, and then the mounting nut is screwed to the bottom end of the screw 103, and then rotated to the bottom end of the mounting nut and the filtering device, and after tightening, the mounting disk 1 is installed in the filtering device.

[0030] Furthermore, the vertical section of the scraper ring 301 is a right triangle, and the inner bottom of the fixed sleeve 3 is fixed with fixed rods 302 in a circular array, and the tops of all the fixed rods 302 are commonly fixed with a connecting ring 303. When the fixed sleeve 3 is working, the connecting ring 303 is connected through the fixed rod 302, and the pulling position is provided through the connecting ring 303.

[0031] The operation process of this embodiment is as follows: when installing the mounting disk 1 in the filter, insert one end of the mounting disk 1 with the screw 103 fixed at the bottom end into the filter and extend it out of the bottom of the filter. At this time, the output pipe 101 extends out of the filter, and then the mounting nut is screwed to the bottom end of the screw 103, and then the nut is turned to be pressed against the bottom end of the filter. After the sealing ring 102 is installed and fastened between the mounting disk 1 and the filter, the gap between the output pipe 101, the mounting disk 1 and the filter is sealed, and the output pipe 101 is connected to the input end of the hydraulic oil equipment used later. Then, hold the connecting ring 303, and put the scraper ring 301 in the fixing sleeve 3 onto the outside of the filter element body 2, and support it on the mounting disk 1. During the filtering process, the hydraulic oil is introduced into the filter. During operation, the deposited impurities generated by the hydraulic oil filtration are deposited in the fixing sleeve 3, and after working for a long time, more impurities are deposited on the surface of the filter element body 2. When impurities are removed, the connecting ring 303 is pulled and connected to the fixing sleeve 3 through the fixing rod 302, driving the fixing sleeve 3 and the scraping ring 301 to rise along the outer side of the filter element main body 2, and the scraping ring 301 scrapes on the surface of the filter element main body 2. Since the vertical section of the scraping ring 301 is a right-angled triangle, the surface impurities of the filter element main body 2 are scraped off together with the oil stains on the surface of the filter element main body 2, and the scraped impurities are deposited on the scraping ring 301 and guided to be deposited on the bottom of the fixing sleeve 3. After the scraping ring 301 leaves the surface of the filter element main body 2, it is set on the outer side of the flushing pipe 403. After the operator uses a brush or other tools to clean the impurities deposited in the fixing sleeve 3, the impurities deposited on the outer side of the filter element main body 2 are cleaned up, and then the connecting ring 303 is held, the scraping ring 301 is put on the outer side of the filter element main body 2, and the connecting ring 303 is pressed down until the bottom end of the fixing sleeve 3 is supported and set on the top of the mounting plate 1, and the cleaning of the deposited impurities filtered out by the filter element is completed.

[0034] Specifically, the bottom end of the filter element body 2 is open, a fixing hole 201 is provided in the center of the top cover of the filter element body 2, and the flushing tube 403 is fixed in the fixing hole 201. When the filter element body 2 is working, the flushing tube 403 is fixed through the fixing hole 201.

[0035] The operation process of this embodiment is as follows: during operation, when the filter element main body 2 works for a certain period of time and the filtering efficiency decreases, the valve on the pipeline connected to the output pipe 101 is closed, and the hydraulic oil for flushing is delivered to the flushing pipe 403 through an external hydraulic oil delivery device, and then the hydraulic oil is delivered to the flushing shell 401 through the flushing pipe 403, and the hydraulic oil is evenly sprayed into the filter element main body 2 from the spray hole 402. The flushing hydraulic oil passes through the inside of the filter element main body 2 and out of the filter element main body 2, flushes out the impurities retained in the filter element main body 2, and flushes the filter element main body 2.
