Description

Technical Field

[0001] The utility model belongs to the technical field of filtering devices, in particular to a T-type magnetic filter. Background Art

[0002] With the rapid development of industrialization, demand for hydraulic systems is increasing across all industries. Hydraulic systems are inseparable from filtration systems, and their use has driven the rapid development of filters and filter elements. Filters are coarse filters, typically installed in low-pressure or return lines of hydraulic systems to protect the system's hydraulic components and prevent large particulate contaminants. Filters offer a simple structure, high flow capacity, and low resistance. Their straightforward operation has led to a wide range of applications across various fields.

[0003] After hydraulic operation and oil return, the oil will contain certain impurities. The impurities in the oil are mainly metal powders such as iron and copper chips. During normal filtration, the metal powders will be adsorbed on the filter medium. When the filter medium is saturated with adsorption, they will accumulate in the filter element. When the pressure difference reaches the bypass valve opening pressure difference, the bypass valve opens and impurities will enter the hydraulic system, thereby increasing hydraulic system wear and reducing service life. Therefore, it is necessary to improve the system. Utility Model Content

[0004] In order to solve the above problems in the prior art, the utility model provides a T-type magnetic filter, which can effectively adsorb metal powder in oil, reduce filter element clogging, and improve filtration quality.

[0026] The filter element 2 includes a filter element body 21, the structure of which is prior art and will not be described in detail here; the filter element body 21 is provided with one or more magnetic steel members 22. As an example, the number of magnetic steel members 22 in this embodiment is four, and the four magnetic steel members 22 are arranged on the filter element body 21 in a circular array; the magnetic steel members 22 are connected to the filter element body 21 by connecting screws 23. According to actual needs, the magnetic steel members 22 are located inside or outside the filter element body 21; the two ends of the connecting screw 23 are connected to the filter element body 21. The nut 24 is detachably connected to the filter element body 21; as an example, the filter element body 21 is cylindrical, the magnetic steel part 22 is cylindrical, and the connecting screw 23 passes through the inner hole of the magnetic steel part 22 and is assembled to the filter element body 21. It should be noted that the filter element body 21 is provided with corresponding designs for the installation of the magnetic steel part 22 and the connecting screw 23, such as the magnetic steel part's yielding part and the connecting screw mounting hole, which are not repeated here; the magnetic steel part 22 has magnetic adsorption ability, and the magnetic steel part 22 can be reused, which saves costs while protecting the hydraulic system.

[0027] In one embodiment, if Figure 1 As shown, the cover plate 3 is detachably connected to the first support plate 5 of the housing 1 via a fastener 4; a first sealing member 6 is provided between the cover plate 3 and the first support plate 5 to prevent oil leakage.

[0028] In one embodiment, since there is an installation avoidance space between the filter element 2 and the filter cavity 11, in order to prevent the filter element 2 from moving up and down in the filter cavity 11 after installation, an elastic member 7 is also included. The elastic member 7 is a spring. The elastic member 7 is located between the top of the filter element 2 and the cover plate 3. The elastic member 7 plays an elastic supporting role for the filter element 2.

[0029] In one embodiment, if Figure 1 and Figure 3 As shown, for the convenience of connection, the ends of the liquid inlet pipe 12 and the liquid outlet pipe 13 are respectively connected with connecting flanges 8 to facilitate the connection of the corresponding oil inlet pipeline and oil outlet pipeline; the overall structure is simplified, the application is wide, the customer is convenient for installation and adjustment, and the installation difficulty and cost are reduced.

[0030] In one embodiment, if Figure 1 As shown, in order to keep the housing 1 in a vertical state, a mounting hole 9 is opened at the bottom of the housing 1, and the mounting hole 9 is locked on the ground by anchor bolts for easy installation.

[0031] In one embodiment, if Figure 1 As shown, an oil drain hole 10 is opened at the bottom of the shell 1, and the oil drain hole 10 is connected to the filter chamber 11; an oil drain plug 15 is detachably connected to the oil drain hole 10, and when oil needs to be drained, the oil drain plug 15 is removed.

[0033] The filter of this embodiment has magnetic adsorption capabilities. A magnetic steel element is installed inside the filter element, i.e., the filter cavity before filtration. The magnetic steel element generates a magnetic field, which attracts magnetic impurities such as iron filings and iron powder generated by the hydraulic system, thereby adsorbing them to the magnetic steel element. The hydraulic system does not need to replace the filter element, and impurities on the magnetic steel element can be cleaned for reuse, making operation simple and convenient. To clean the filter element, the cover plate is removed and the filter element is removed, which is convenient and quick.

[0034] The filter element is a magnetic filter element. When the oil enters the filter from the liquid inlet, because the oil carries a lot of metal impurities such as iron filings and iron powder, a part of it will be captured by the magnetic field generated by the magnetic steel parts and adsorbed on the magnetic steel parts, while clean oil enters the hydraulic system, improving the filtration efficiency and service life; effectively solving the problem of excessive metal impurities in the hydraulic system, reducing damage and saving costs; the filter element is a magnetic filter element, which has magnetic adsorption ability. The magnetic filter element can be reused, saving costs while protecting the hydraulic system.
