An automatic magnetic filtration device

Abstract

This utility model discloses an automatic magnetic filtration device, including a cylindrical body. A first O-ring and a second O-ring are fixedly installed inside the cylindrical body, with the second O-ring installed inside the first O-ring. In this design, the device mainly consists of an upper flange, a magnetic rod, and a cylinder. These components are installed in the cylindrical body. Flowing liquid carrying ferromagnetic contaminants flows through the magnetic field area formed by the upper flange and the magnetic rod. Under the action of magnetic force, the ferromagnetic contaminants are adsorbed onto the sliding sleeve outside the magnetic rod. After a certain time or degree of accumulation, the main valve closes, the bypass valve opens, and the magnetic rod is lifted by the cylinder. The contaminants are discharged through the bypass drain valve. After discharge, the bypass valve closes, the main valve opens, and the filtration device begins the next working cycle. Through this structure, the device isolates the magnet and the adsorbed material using a non-magnetic material, effectively eliminating the influence of magnetic force on the adsorbed material during the cleaning process.

Description

Technical Field

[0002] In the metallurgical industry, especially in processes such as cold-rolled steel sheet and aluminum foil rolling, emulsions play a crucial role. They serve functions such as lubrication, cooling, cleaning, and rust prevention. However, during recycling, emulsions can become contaminated by various impurities, affecting their performance and the quality of rolled products. Furthermore, emulsions contain ferromagnetic particulate impurities, and excessive amounts of these impurities can clog flow meters. Therefore, we propose a magnetic filter.

[0003] To address the aforementioned issues, patent document publication number CN210945216U describes a magnetic filter comprising a tube body, an internal guide rod, a magnetic rod fixedly connected to the surface of the guide rod, a first connecting block fixedly connected to the top of the guide rod, connecting rods fixedly connected to both sides of the first connecting block, a slider fixedly connected to one side of the connecting rod, a sliding groove formed on the surface of the tube body, and the slider slidingly connected to the sliding groove, and a filter screen provided at the bottom of the tube body.

[0004] However, in actual use, it still has some shortcomings, such as the existing magnetic filtration devices all have the problem of not being able to remove adsorbed substances in a timely manner or not removing them completely, which makes the magnetic filtration devices have certain defects in use.

[0005] Therefore, an automatic magnetic filtering device was proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic magnetic filtration device to solve the problem that existing magnetic filtration devices cannot remove adsorbed substances in a timely manner or the removal is incomplete.

[0008] The system also includes an upper flange, which is detachably installed inside the cylinder. The bottom of the upper flange contacts the top of the cylinder. Six sliding sleeves are fixedly installed at the bottom of the upper flange. The six sliding sleeves are arranged in a ring at the bottom of the upper flange, and the distance between each sliding sleeve is equal. Several No. 4 screws are arranged in a ring at equal intervals at the top of the upper flange. A washer is installed between each No. 4 screw and the upper flange.

[0009] The system also includes a first connecting plate, a nut, and a cylinder. The bottom of the first connecting plate contacts the top of the upper flange. The first connecting plate is detachably installed on the top of the upper flange. Six magnetic rods are installed on the bottom of the first connecting plate. The six magnetic rods are arranged in a ring at the bottom of the first connecting plate, and the distance between each magnetic rod is equal. The tops of the six magnetic rods are connected to the bottom of the first connecting plate by nuts. Guide rings are fixedly installed at the bottom of each of the six magnetic rods. The six magnetic rods are slidably connected to the interior of six corresponding sliding sleeves. The cylinder is located at the bottom of the first connecting plate and is positioned in the middle of the six magnetic rods.

[0010] The system also includes a second connecting plate. Six No. 1 screws are installed at the protruding corners on the top of the second connecting plate, and six sleeves are installed at the protruding corners on the bottom of the second connecting plate.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, the device mainly consists of components such as an upper flange, a magnetic rod, and a cylinder. These components are installed in the cylinder. The flowing liquid carrying ferromagnetic contaminants flows through the magnetic field area formed by the upper flange and the magnetic rod. Under the action of magnetic force, the ferromagnetic contaminants are adsorbed onto the sliding sleeve outside the magnetic rod. After accumulating for a certain time or to a certain extent, the main valve closes, the bypass valve opens, and the magnetic rod is lifted by the action of the cylinder.
