Description

Technical Field

[0001] The invention relates to the field of filters, and in particular to a filter magnetization device. Background Art

[0002] Wear and tear during engine use is a common problem. Wear and tear will cause the engine to produce a large amount of iron powder. The iron powder circulates continuously in the engine with the oil, and due to continuous wear, the increase of iron powder will cause the engine accuracy to decrease. An oil filter is installed on the engine to filter out the iron powder or other impurities in the oil. However, due to the large aperture of the filter mesh inside the filter element, it can only filter larger particles of iron powder, and the small particles cannot be filtered by the dust filter, causing the iron powder to circulate in the engine with the oil, increasing the clearance between the transmission parts, and eventually leading to an overhaul of the engine or even scrapping, causing fatal damage to the car.

[0003] For this reason, filter magnetization devices have appeared on the market. Filter magnetization devices can effectively absorb iron powder generated by engine wear. For example, patent application number: CN201921747899.8 discloses a filter magnetization device, including a fixed disk, a claw belt and a magnetic part. The claw belt is provided with multiple strips, and all are arranged around the edge of the fixed disk. The first end of the claw belt is connected to the fixed disk, and the second end is designed to be bent; the magnetic part is arranged at the bottom of the fixed disk and the second end of the claw belt, so that the bottom of the fixed disk can be adsorbed and fixed to the top of the filter, and the second end of the claw belt can be adsorbed and fixed to the outside of the filter column. This type of magnetization device arranges multiple magnetic parts at intervals on the surface of the filter, and the iron powder in the filter is adsorbed by the magnetic parts. However, there is still a lot of space between the magnetic parts of this type of magnetization device, and the adsorption range of the magnetic parts is small. It can only adsorb the iron powder at the position of the magnetic parts, resulting in some iron powder flowing into the engine.

[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0005] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a filter magnetization device.

[0006] The present invention can be implemented by the following technical solutions:

A magnetic ring is put on the filter housing, and each magnetic ring is fixed by a fixing rod. The positioning block is slidably fixed on the fixing rod. After the positioning block presses against the magnetic ring from both sides of the magnetic ring, the positioning bolt on the positioning block is turned.

After each magnetic ring is fixed, one end of the strap passes through each slip ring in turn, and the end of the strap passes through the fixing block and then the strap is tightened. After the strap is tightened, the fixing bolt is turned. Since the fixing bolt is threadedly connected to the threaded pipe, when the fixing bolt is rotated, the bottom of the fixing bolt is squeezed with the strap to fix the strap on the fixing block. After the strap is fixed, the magnetic ring is fixed to the outside of the housing. Multiple magnetic rings are fixed around the filter housing. When the engine oil flows in the filter, the iron powder in the engine oil can be effectively adsorbed on the surface of the housing.

[0008] Preferably, a plurality of screw rods are fixed on the upper side of the top plate, and a nut rotatably connected to the fixing rod is provided at the end of the fixing rod, and the nut is threadedly connected to the screw rod. A corresponding number of fixing rods are selected according to the specifications of the filter, and the fixing rods are fixed to the top plate by assembling the nuts on the fixing rods with the screw rod threads.

The strap passes between the two support rollers, and the support rollers support the strap to prevent the strap from being worn and broken.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] Multiple magnetic rings are fixed around the filter housing. When the oil flows in the filter, it will pass through the magnetic field generated by the magnetic rings, which can effectively adsorb the iron powder in the oil to the surface of the housing. BRIEF DESCRIPTION OF THE DRAWINGS
