[0018] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0019] like Figures 1 to 3 As shown, a machining waste oil filtration device includes a filter tank 1 and a settling tank 2. The settling tank 2 is located below the filter tank 1, and a discharge pipe 5 is provided at the lower end of the filter tank 1, through which the filter tank 1 communicates with the settling tank 2. The coolant to be filtered first passes through the filter tank 1, leaving the waste in the filter tank 1, and the filtered filtrate then enters the settling tank 2 for collection.

[0020] The settling tank 2 and the filter tank 1 are detachably connected. In this application, the filter tank 1 is placed above the settling tank 2. In order to prevent the relative positions of the two from shifting, several recessed positioning grooves are provided at the lower end of the filter tank 1, and several protruding positioning blocks are provided at the corresponding positions at the upper end of the settling tank 2. The positioning blocks are inserted into the positioning grooves to fix the filter tank 1 and the settling tank 2 relative to each other.

[0021] A fixed column 3 is installed inside the filter tank 1. The two ends of the fixed column 3 are fixedly connected to the inner walls of the front and rear sides of the filter tank 1, respectively. The fixed column 3 is a triangular prism with a triangular cross-section; its lower end is a flat surface, and its upper end has two inclined planes, dividing the filter tank 1 into left and right sides. To prevent the coolant to be filtered from overflowing the fixed column 3, a partition plate 7 is installed above the fixed column 3. The height of the uppermost part of the partition plate 7 is similar to the height of the uppermost part of the filter tank 1, ensuring that the coolant does not overflow the partition plate 7.

[0022] Insertion interfaces are provided on both the left and right side walls of the filter tank 1. Filter plates 4 are inserted into these interfaces horizontally into the filter tank 1. A hook block 6, a right-angled elongated block, is provided on the lower end face of the fixing post 3, forming a groove between the hook block 6 and the lower end face of the fixing post 3. When the filter plate 4 is inserted below the fixing post 3, it enters the groove, which supports one side of the filter plate 4 to prevent it from falling. The end of the filter plate 4 away from the hook block 6 is supported by the insertion interface, ensuring the filter plate 4 is stably fixed.

[0023] To prevent coolant from flowing out of the connector during filtration, a sealing block 8 is provided at the end of the filter plate 4 away from the groove. Sealing blocks 8 are provided on both the upper and lower sides of the filter plate 4, and one side of the sealing block 8 is inclined. When the sealing block 8 moves with the filter plate 4 to the connector, it will insert into the connector and seal the connector to prevent coolant from flowing out of the connector.

[0024] The filter plate 4 is provided with several protruding ridges 9, arranged horizontally on the filter plate 4 with the direction from the insertion interface to the groove as the straight line, that is, the several protruding ridges 9 are arranged parallel to the insertion interface. The filter holes on the filter plate 4 are located between two protruding ridges 9. When it is necessary to remove the filter plate 4 from the insertion interface, the several protruding ridges 9 can block the waste on the filter plate 4 and prevent the waste from falling into the settling tank 2.

[0025] The side wall of the filter tank 1 is provided with several clips 10. In this design, the clips 10 are rotatably connected to the side wall of the filter tank 1. When the filter plate 4 is inserted into the filter tank 1, by rotating the clips 10, one end of the clip 10 abuts against one side of the filter plate 4, thus fixing the filter plate 4 and preventing it from moving out of the insertion interface. The filter plate 4 is provided with a pull ring 11. After opening the clips 10, the filter plate 4 can be easily removed from the filter tank 1 through the pull ring 11.

[0026] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
