The first motor drives the arc-shaped bin to rotate, which can not only stir the hydraulic oil in the processing bin to fully mix the viscous hydraulic oil at the bottom, but also, under the action of centrifugal force, the hydraulic oil in the arc-shaped bin can penetrate from the filter holes to achieve preliminary filtration, effectively improving the filtration efficiency and quality, and ensuring the filtration efficiency of the hydraulic oil; Extrusion assembly, the bottom of the first motor is also rotatably connected to the extrusion assembly, the second motor in the extrusion assembly drives the arc rod and the extrusion plate to move, cooperates with the first spring and the airbag, and strongly squeezes the hydraulic oil in the arc bin, so that the hydraulic oil is filtered through the filter hole more quickly, further improving the filtering efficiency, and impurities are temporarily stored in the arc bin. After the work is completed, they can be conveniently taken out from the arc bin, which is simple to operate and easy to maintain, reducing the time and cost of cleaning impurities, and improving the overall practicality of the equipment; A filter hole is provided on the top of the arc-shaped bin.

The first motor 43 drives the arc chamber 41 to rotate, which can not only stir the hydraulic oil in the processing chamber 2 to fully mix the viscous hydraulic oil at the bottom, but also, under the action of centrifugal force, the hydraulic oil in the arc chamber 41 can penetrate from the filter hole 46 to achieve preliminary filtration, effectively improve the filtration efficiency and quality, and ensure the filtration efficiency of the hydraulic oil; The arc-shaped bin 41, the bottom of the first motor 43 is rotatably connected to the arc-shaped bin 41; The bottom of the extrusion assembly 45, the first motor 43 is also rotatably connected to the extrusion assembly 45, and the second motor 451 in the extrusion assembly 45 drives the arc rod 452 and the extrusion plate 453 to move, and cooperates with the first spring 455 and the air bag 454 to strongly squeeze the hydraulic oil in the arc bin 41, so that the hydraulic oil is filtered through the filter hole 46 more quickly, further improving the filtering efficiency, and impurities are temporarily stored in the arc bin 41. After the work is completed, it can be conveniently taken out from the arc bin 41, which is simple to operate and easy to maintain, reducing the time and cost of cleaning impurities, and improving the overall practicality of the equipment; The filter hole 46 is provided at the top of the arc-shaped bin 41 .

[0021] The first motor 43 is fixedly connected to the top of the processing chamber 2 through a bracket 42 .

[0022] The bottom of the first motor 43 is rotatably connected to the arc-shaped bin 41 through a connecting rod 44, and the outer wall of the extrusion assembly 45 is fixedly connected to the outer wall of the connecting rod 44; Combined with Figure 6 As shown, when the first motor 43 is powered on and started, the arc bin 41 is driven to rotate through the connecting rod 44. When the arc bin 41 is located in the processing bin 2 and rotates, the hydraulic oil is stirred, thereby mixing the viscous hydraulic oil in the bottom part. Moreover, under the rotation of the arc bin 41, the hydraulic oil in the arc bin 41 penetrates out from the filter hole 46 under the action of centrifugal force.

[0023] The extrusion assembly 45 includes a second motor 451 , and an outer wall of the second motor 451 is fixedly connected to an outer wall of the connecting rod 44 .

[0024] The outer wall of the second motor 451 is rotatably connected to one end of an arc-shaped rod 452 , and the arc-shaped rod 452 has the same axis as the arc-shaped bin 41 .

[0025] The other end of the arc rod 452 is fixedly connected to a pressing plate 453 , and the outer wall of the pressing plate 453 is fixedly connected to an air bag 454 .

[0026] The outer wall of the airbag 454 is fixedly connected to one end of the first spring 455, and the other end of the first spring 455 is fixedly connected to the rubber plate 456. The rubber plate 456, the first spring 455, the airbag 454 and the extrusion plate 453 are inserted into the arc-shaped bin 41; The second motor 451 is powered on to start and drives the arc rod 452 to rotate. A control element is provided in the second motor 451, so that the second motor 451 rotates and drives the arc rod 452 to extend into the arc bin 41, and then leaks out of the arc bin 41 in the opposite direction. When the extrusion plate 453 moves toward the arc bin 41, it will squeeze the hydraulic oil in the arc bin 41. The first spring 455 drives the rubber plate 456 to squeeze the hydraulic oil in the arc bin 41. The rubber plate 456 is made of rubber material and has a size larger than the inner diameter of the arc bin 41, so it will fit on the inner wall of the arc bin 41 for extrusion. At this time, the first spring 455 will squeeze the rubber plate 456 while squeezing the airbag 454, so that the airbag 454 will expand toward the outer circle, so it will also fit on the inner wall of the arc bin 41 for extrusion, and then the hydraulic oil squeezed in the arc bin 41 will be filtered by the filter hole 46. The impurities are temporarily stored in the arc-shaped bin 41 and are taken out from the arc-shaped bin 41 after the work is completed.

[0027] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The bottom of the processing chamber 2 is fixedly connected with an impact mechanism 5. The impact mechanism 5 at the bottom of the processing chamber 2 generates airflow through a fan 51, so that more bubbles are generated in the processing chamber 2, which disperses the density of the hydraulic oil and reduces its viscosity. On the one hand, it is beneficial to the subsequent filtering process and makes it easier for the hydraulic oil to pass through the filtering device; on the other hand, it also helps to improve the working efficiency of the entire filtering system. The impact mechanism 5 includes an airflow pipe 52, which is fixedly connected to the bottom of the processing chamber 2. The bottom of the airflow pipe 52 is fixedly connected with the fan 51, and the inner wall of the airflow pipe 52 is fixedly connected with one end of the second spring 53. The airflow pipe 52 The second spring 53 is tilted toward the bottom of the arc-shaped bin 41, and the airflow drives the hydraulic oil to flow toward the arc-shaped bin 41, which is convenient for the filter mechanism 4 to filter the hydraulic oil. At the same time, the elastic band 54 and the scraper rod 55 in the airflow tube 52 move under the action of the airflow to stir the hydraulic oil deposited at the bottom of the processing bin 2, thereby reducing the deposition of impurities, further optimizing the filtering effect, ensuring the stable and efficient operation of the oil filter, and improving the filtering efficiency of the hydraulic oil. The other end of the second spring 53 is fixedly connected to the scraper rod 55, and the inner wall of the second spring 53 is fixedly connected to one end of the elastic band 54. The airflow tube 52 is positioned toward the bottom of the arc-shaped bin 41; Combined with Figure 8 As shown, the fan 51 is connected to the bottom of the processing chamber 2 through the airflow pipe 52. When the fan 51 is continuously started, it blows out airflow, so the hydraulic oil in the processing chamber 2 will not flow into the fan 51. Then, under the flow of airflow, more bubbles are generated in the processing chamber 2. The bubbles will disperse the density of the hydraulic oil and reduce the viscosity of the hydraulic oil. The airflow pipe 52 is inclined toward the bottom of the arc-shaped bin 41, so the airflow drives the hydraulic oil to flow into the arc-shaped bin 41, thereby facilitating subsequent filtering by the filtering mechanism 4; When the airflow flows in the airflow pipe 52 , it drives the elastic belt 54 to move, and then drives the scraper rod 55 and the second spring 53 to move, so as to stir the hydraulic oil deposited at the bottom of the processing chamber 2 .
