DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Fuel filters can effectively filter out particles, water and impurities in the fuel, protect the internal combustion engine from wear and damage, ensure the stable performance of the internal combustion engine and extend its service life. The importance of the stable operation of the internal combustion engine cannot be ignored. At the same time, clean fuel can burn more fully, improve fuel economy, reduce exhaust emissions, and save energy and protect the environment. Therefore, it is also very important to replace the fuel filter regularly to avoid filter blockage affecting fuel flow, thereby ensuring the stable operation of the internal combustion engine. In a nutshell, the fuel filter plays an irreplaceable role in the normal operation and performance maintenance of the internal combustion engine.

[0030] The commonly used fuel filter structure on the market is mainly composed of a housing, a filter element, a filter element and other components. The housing protects the internal filter element, which is usually made of metal or plastic and has an oil inlet and an oil outlet; the filter element is the core of the filter, and common types include paper filter elements, microporous filter membranes, etc., which are responsible for removing impurities in the fuel. Its working principle is to use the fine pore screening effect of the filter element to block particles and pollutants from entering the fuel system, while using the pre-filter layer to filter large particles first to extend the life of the filter element. There is also a separation layer inside the filter element to separate water and tiny particles to ensure fuel cleanliness. In addition, the filter is also equipped with a pressure relief valve to prevent excessive internal pressure, a temperature sensor to monitor the operating temperature of the filter element, and a fuel metering device to accurately control the amount of fuel entering the engine.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 4 As shown, this embodiment provides a shaft-driven high-efficiency diesel filter device, comprising:

[0033] The filter body 1 includes a main oil chamber 2 and a power chamber 3 which are arranged correspondingly above and below;

[0034] The filter rotating assembly 4 includes an iron core frame 43 which is rotatably arranged in the main oil chamber 2. A paper filter element 44 for filtering diesel is arranged on the iron core frame 43. Diesel from the outside enters the inner cavity of the paper filter element 44 and enters the main oil chamber 2 after being filtered.

The motor 52 is fixed to the bottom of the power chamber 3 through the motor seat 51. The induction wheel seat 58 is installed on the upper layer of the power chamber 3, and the coupling bearing 57 is fixed on the induction wheel seat 58, and its axis and the axis of the first bearing and the second bearing 46 are all on the filter axis.

[0059] In one embodiment of the present application, the outer shell of the filter body 1 is made of brass.

[0060] The present invention can form an efficient magnetic coupling gear structure by accurately configuring the number of induction magnets 56, transmission magnets 435 and iron blocks 11, so that the motor can output a higher speed under a smaller volume and load, thereby improving the working efficiency of the filtering rotating component.

[0061] Working process:

[0062] When the filter is working, the motor 52 is turned on, and the driving wheel 53 drives the induction wheel 55 to rotate around the filter axis through the belt 54. The induction magnet 56 in the induction wheel 55 also rotates around the filter axis. At this time, the direction of the magnetic flux lines in the iron block 11 is offset with the moving induction magnet 56, causing the magnetized magnetic moment in the iron block 11 to point in the opposite direction of the incoming direction, thereby driving the four transmission magnets 435 above to move in the opposite direction of the induction magnet 56, driving the entire filter rotating assembly 4 to rotate continuously around the filter axis, and according to the magnetic field modulation theory, the source magnetic field generated by the induction magnet 56 is 6 pairs of poles, After modulation of the eight iron blocks 11, a modulated magnetic field with two pairs of poles is generated in the air gap, which couples with each other to generate torque and plays the role of magnetic coupling gears. Therefore, the rotation speed of the filtering rotating component 4 is increased to three times the rotation speed of the induction magnet 56, and the low-temperature diesel enters the main oil chamber 2 from the upper oil inlet channel 6. Since a large amount of heat is generated by the magnetic induction transmission, the spiral fan blades 434 stir and transfer the heat evenly to the diesel and reduce its viscosity. At the same time, the diesel passes through the filter paper core under the centrifugal effect of the rotation of the filtering rotating component 4, and the rotation of the spiral fan blades 434 stirs the filtered diesel upward to make it flow out from the oil outlet channel 8.

[0063] Beneficial effects of the present invention:

[0064] 1. The magnetic shaft coupling assembly 5 of the present invention generates a large amount of heat due to magnetic induction transmission when working, and transfers the heat evenly to the diesel in the filter through the spiral blades 434, thereby reducing the viscosity of the diesel and improving the filtering efficiency.

[0065] 2. The present invention uses a rotatable filter rotating assembly 4 structure, which can quickly throw diesel out of the paper filter element 44 through centrifugal action during rotation, thereby improving the filtering efficiency of the filter.

[0066] 3. The filter rotating assembly 4 and the magnetic shaft coupling assembly 5 used in the present invention are respectively arranged in the main oil chamber 2 and the power chamber 3. Only the power chamber 3 is connected to the line, and the filter rotating assembly 4 and the magnetic shaft coupling assembly 5 operate without contact. Therefore, the two components are independent of each other, do not require lubrication, and have high reliability.

[0067] 4. The spiral blades 434 of the present invention stir the filtered diesel in the main oil chamber 2 upward, which can promote its rapid discharge from the oil outlet channel 8 and improve the working efficiency of the entire filter.

[0068] 5. The present invention can form an efficient magnetic gear structure by accurately configuring the number of induction magnets 56, transmission magnets 435 and iron blocks 11, so that the motor 52 can output a higher speed under a smaller volume and load, thereby improving the working efficiency of the filtering rotating component 4.
