Description

Technical Field

[0001] The present application relates to the field of filtering technology, and in particular to a hydraulic oil filtering device. Background Art

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] During the assembly process of the bulldozer, iron filings from the raw materials themselves and impurities such as iron filings generated during the assembly process may enter the hydraulic system and cause contamination of the hydraulic oil. Therefore, it is necessary to filter the hydraulic oil of the hydraulic system to remove the iron filings. The existing filtering method is to start the circulating hydraulic system and filter the hydraulic oil through the filter element during the circulation process, which can effectively remove these iron filings and impurities. However, the existing filter element is not convenient to disassemble in the circulating hydraulic system, which results in the filter element being unable to be cleaned in time after being full of iron filings, affecting the subsequent filtering work. Therefore, it is necessary to design a hydraulic oil filtering device that is easy to disassemble and clean. Utility Model Content

[0005] The purpose of this application is to provide a hydraulic oil filtering device, which connects the base and the upper cover through a support frame to form a vertical frame structure, which is convenient for installation and disassembly. After the filtering is completed, the entire filtering device can be directly removed from the hydraulic system, and then each magnet can be cleaned, thereby improving the efficiency of disassembly and cleaning.

[0008] As a further preferred embodiment, the base is provided with four mounting grooves, which are evenly distributed on the base, and the support frame is composed of three support bars, which respectively correspond to the three mounting grooves on the base, and the support bars are fixedly connected to the mounting grooves on the base.

[0009] As a further preference, the mounting groove is a rectangular groove body with the edge of the base recessed downward.

[0010] As a further preferred embodiment, a handle is further included, and a side of the upper cover away from the base is fixedly connected to the handle.

[0011] As a further preference, the base and the upper cover are circular, and the diameter of the upper cover is larger than the diameter of the base.

[0020] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0021] A hydraulic oil filter device, such as Figure 1-3As shown, it includes: a base 2, an upper cover 1, a limit plate 5, a support frame 3 and a magnet 6, the base 2 and the upper cover 1 are fixedly connected by the support frame 3, the base 2 and the upper cover 1 are parallel to each other, the support frame 3 and the base 2 are perpendicular to each other, the base 2 and the support frame 3 are welded and fixed, the upper cover 1 and the support frame 3 are welded and fixed, the limit plate 5 is a semicircular ring, there are multiple limit plates 5, and the multiple limit plates 5 are arranged on the support frame 3 in parallel with each other, the limit plates 5 and the support frame 3 are welded and fixed, the limit plates 5 and the base 2 are parallel to each other, and the magnet 6 is placed on the limit plate 5. In this way, the device is placed in a hydraulic system. When the hydraulic oil passes through the magnet 6, the magnet 6 absorbs the iron filings in the hydraulic oil. After the adsorption is completed, the device is taken out as a whole, and then the magnet 6 is removed for cleaning, so that it can be easily disassembled.

[0022] like Figure 1 As shown, the base 2 is provided with four mounting grooves 4, which are evenly distributed on the base 2, and the support frame 3 is three support bars 8, which correspond to the three mounting grooves 4 on the base 2 respectively, and the support bars 8 are fixedly connected with the mounting grooves 4 on the base 2, so that the base 2 and the upper cover 1 can be fixed. In this way, the magnet 6 can be placed on the limiting plate 5 through the direction of the remaining mounting groove 4 without the support bar 8, which facilitates the installation and removal of the magnet 6 while ensuring the supporting effect of the support bar 8.

[0023] like Figure 1 As shown, the installation groove 4 is a rectangular groove body with the edge of the base 2 recessed downward, which facilitates the installation of the support bar 8.

[0024] like Figure 2 As shown, it also includes a handle 7. The side of the upper cover 1 away from the base 2 is fixedly connected to the handle 7. The handle 7 is used to facilitate the removal of the entire device for subsequent cleaning.

[0025] like Figure 1 As shown, the base 2 and the upper cover 1 are circular, and the diameter of the upper cover 1 is larger than the diameter of the base 2, which is convenient for installation.

[0026] A sealing ring is provided at one end of the upper cover 1 close to the limiting plate 5 to prevent leakage of hydraulic oil.

[0027] like Figure 2 As shown, the distance between adjacent limiting plates 5 is greater than or equal to the thickness of the magnet 6, which facilitates the installation of the magnet 6.

[0028] The magnet 6 is a ring magnet 6, which is convenient for disassembly.

[0029] like Figure 2As shown, there are multiple magnets 6 , and a gap is left between adjacent magnets 6 for the installation position of the magnet 6 to facilitate the flow of hydraulic oil between the magnets 6 .

[0030] In the technical solution of the present application, a mounting hole is opened in the hydraulic oil tank 9 of the hydraulic system, and the filter device is placed in the hydraulic oil tank 9, such as Figure 3 As shown, the hydraulic oil flows from the liquid inlet of the hydraulic oil tank 9 to the liquid outlet, and will pass through the filtering device, so that the iron filings residue in the hydraulic oil can be adsorbed by the magnet 6 of the filtering device. After the adsorption and cleaning of the magnet 6 is completed, the liquid inlet and the liquid outlet of the hydraulic oil tank 9 are closed, so that the filtering device can be safely taken out, and the device can be taken out of the hydraulic oil tank 9 as a whole by pulling the handle 7. After that, the magnet 6 is removed from the limiting plate 5 for cleaning, and the adsorbed iron filings residue is cleaned. Then, the iron filings residue remaining on the base 2, the upper cover 1, the limiting plate 5, and the support frame 3 are cleaned, and finally the magnet 6 is installed back on the limiting plate 5, thus completing the cleaning of the filtering device. Finally, the cleaned filtering device is installed back into the hydraulic oil tank 9, so that the next hydraulic oil cleaning can be carried out.

[0031] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
