Description

Technical Field

[0001] The utility model belongs to the technical field of fuel tank oil purification devices, and more specifically relates to a hydraulic fuel tank oil purification and cleaning device. Background Art

[0002] Metal impurities such as iron filings are common pollutants in hydraulic oil circuits. The sources of these metal impurities mainly include metal chips, rust, and welding slag generated during the wear, oxidation corrosion, welding, and processing of hydraulic components. These metal impurities can cause problems such as increased wear of hydraulic components, aging of seals, deterioration of oil, and system failures, thereby reducing the working efficiency and lifespan of the system. Therefore, purifying metal impurities in the hydraulic oil circuit is a very important task.

[0003] Currently, metal impurities are mostly purified by adding magnetic filters to the inlet pipeline of the fuel tank. However, the purification effect is limited, and some metal impurities will still enter the fuel tank, affecting the normal operation of the hydraulic system. To address this problem, one solution is to directly place a strong magnetic rod or a strong magnetic plate into the fuel tank to adsorb and purify the metal impurities in the fuel tank. However, the adsorption capacity of the strong magnetic rod or the strong magnetic plate is limited, and the placement position and quantity of the strong magnetic rod or the strong magnetic plate need to be considered. Too much or too little will affect the purification effect. In addition, the strong magnetic rod or the strong magnetic plate needs to be regularly inspected and replaced, and the replacement of the strong magnetic rod or the strong magnetic plate is not convenient.

[0004] Based on the above problems, a hydraulic fuel tank oil purification and cleaning device is needed. Summary of the Utility Model

[0006] To achieve the above object, the utility model is realized through the following technical solutions: A hydraulic fuel tank oil purification and cleaning device is installed at the manhole of the hydraulic fuel tank, and includes: a fuel tank hole cover, a connecting rod, a strong magnetic frame, a motor, and a stirring paddle; the fuel tank hole cover is provided with mounting holes corresponding to the original manhole cover of the hydraulic fuel tank; the connecting rod is a hollow tube and is arranged and installed on the fuel tank hole cover; the strong magnetic frame is a circular ring frame provided with a number of strong magnetic rods, and the strong magnetic frame is arranged and installed on the connecting rod; the motor is installed on the top of the fuel tank hole cover, and the output shaft of the motor passes through the central hole of the connecting rod; the stirring paddle is arranged and installed on the output shaft of the motor.

[0007] Further, a bearing is arranged inside the tube wall of the connecting rod, and the output shaft of the motor passes through the bearing for installation.

[0008] Further, a sealing plug is arranged at the bottom inside the tube wall of the connecting rod.

[0009] Further, a plurality of stirring paddles are mounted on the output shaft, including: Stirring Paddle I and Stirring Paddle II.

[0010] Further, the motor is electrically connected to a controller, and the motor is controlled through the controller; the motor is electrically connected to the main control of the hydraulic system.

[0011] It can be understood that the shape of the fuel tank hole cover can be changed according to the manhole shape of the hydraulic fuel tank.

[0012] The beneficial effects of the present utility model: The present utility model drives Stirring Paddle I and Stirring Paddle II to rotate through the driving motor, enabling the metal impurities suspended in the oil to be easily adsorbed by the strong magnetic rods on the strong magnetic frame, effectively purifying the metal impurities in the oil, and improving the operation efficiency and stability of the hydraulic system.

[0019] The shape of the oil tank hole cover 1 is set according to the shape of the manhole of the hydraulic oil tank, and a mounting hole corresponding to the original manhole cover of the hydraulic oil tank is set on the oil tank hole cover 1; the connecting rod 3 is a hollow tube, and the connecting rod 3 is set and installed on the oil tank hole cover 1, located in the middle position of the oil tank hole cover 1; the strong magnetic frame 4 is a circular frame with a plurality of strong magnetic bars 401, and the strong magnetic frame 4 is set and installed on the connecting rod 3; the motor 2 is installed on the top of the oil tank hole cover 1, and the output shaft 201 of the motor 2 passes through the center hole of the connecting rod 3, and bearings 301 are set at the upper and lower ends of the tube wall of the connecting rod 3. The output shaft 201 of the motor 2 is installed and fixed through the bearing 301, so that the output shaft 201 can rotate freely, avoiding the occurrence of bending or deformation of the output shaft 201, and improving the service life and stability of the device; a sealing plug 302 is also set at the bottom of the tube wall of the connecting rod 3 to ensure the sealing effect and prevent oil from entering the connecting rod 3; the stirring paddle I5 is set and installed on the output shaft 201 of the motor 2.

[0020] After the installation is completed, the utility model device is installed at the manhole of the oil tank. By driving the motor 2, the stirring paddle Ⅰ5 installed on the output shaft 201 of the motor 2 will be driven to rotate, which can effectively stir the oil, so that the metal impurities suspended in the oil are easily adsorbed by the strong magnetic rod 401 on the strong magnetic frame 4, thereby achieving the purpose of purifying the oil. After using it for a period of time, the utility model device can be taken out to clean the metal impurities attached to the strong magnetic rod 401.
