[0037] like Figures 1 to 10 As shown, the defoaming unit based on machine tool cutting fluid includes the following embodiments.

[0038] like Figure 1 - Figure 7 As shown, Embodiment 1: A defoaming unit based on machine tool cutting fluid includes a storage tank 1 for holding cutting fluid. The machine tool's cutting fluid is filtered by the machine tool, and the recovered cutting fluid is injected into the storage tank 1 for storage.

[0039] In actual use, foam will appear on the surface of the filtered cutting fluid. A large amount of foam will leak out of the storage tank, causing pollution around the storage tank and deteriorating the working environment. Alternatively, the cutting fluid may also leak out due to the foam leaking out of the storage tank 1, resulting in a rapid decrease in the amount of cutting fluid. Furthermore, the presence of foam in the cutting fluid will affect its performance during use. Therefore, it is necessary to defoam the foam in the cutting fluid. Existing defoaming devices often directly break up the foam inside the storage tank 1, which cannot completely eliminate the foam and will generate new foam due to the large-scale agitation. Another method is to use a suction head to remove the foam, but this method will also remove a large amount of cutting fluid, increasing the workload. Therefore, this solution adopts a method in which a connecting frame 5 is installed inside the storage tank 1. The connecting frame 5 is attached to the inner wall of the storage tank 1, and a U-shaped plate 501 is fixedly connected to the bottom of the connecting frame 5. An adsorption sponge 5012 for adsorbing the foam at the edge of the storage tank 1 is installed inside the U-shaped plate 501.

[0040] The inside of the liquid storage tank 1 is symmetrically provided with two fixed sliding blocks 3, the two fixed sliding blocks 3 are respectively slidably connected to the two sides of the connecting frame 5, and a collecting assembly 4 for collecting foam is fixedly connected between the two fixed sliding blocks 3. The top of the liquid storage tank 1 is provided with a driving assembly 2, the driving assembly 2 drives the fixed sliding block 3 to move left and right, so that the collecting assembly 4 collects the foam in the liquid storage tank 1. The outside of the liquid storage tank 1 is provided with a treatment assembly 9 for defoaming treatment.

[0041] The collecting assembly 4 comprises a collecting frame 401 fixedly connected between the two fixed sliding blocks 3, and a flow guide frame 402 is fixedly connected to the two sides of the collecting frame 401 and communicates with the collecting frame 401. An opening is arranged at the end of the flow guide frame 402 away from the collecting frame 401, and a baffle 4021 is arranged at the opening. A liquid level sensor 6 for detecting the water level is fixedly connected to the outside of the collecting frame 401.

The outer sides of the two reciprocating lead screws 201 are connected with moving blocks 203 through ball nut pairs. The bottoms of the two moving blocks 203 are fixedly connected with hydraulic telescopic rods 204, and the two hydraulic telescopic rods 204 are fixedly connected with the fixed sliding blocks 3. Two first motors 205 are installed on the outer sides of the support frames 202, and the two first motors 205 are fixedly connected with the two reciprocating lead screws 201.

[0043] In specific implementation, the bubble detection sensor 12 is installed in the liquid storage tank 1. When the bubble detection sensor 12 detects that there is foam in the cutting fluid, the bubble detection sensor 12 can adopt CPR016-13-16-GB, and the equipment is adapted. The hydraulic telescopic rod 204 at the bottom of the moving block 203 is started to push the fixed sliding block 3 to descend, and then the fixed sliding block 3 drives the connecting frame 5 and the collecting assembly 4 to sink into the cutting fluid, so that the openings provided by the flow guide frames 402 on the two sides of the collecting assembly 4 are kept horizontal with the surface. The foam is suspended on the surface of the cutting fluid, so that the foam enters the inside of the collecting frame 401 together with part of the cutting fluid, and the baffle 4021 is arranged at the opening of the flow guide frame 402 to block the cutting fluid, thereby reducing the cutting fluid. The reciprocating lead screw 201 drives the moving block 203 to move, and then the fixed sliding block 3 drives the collecting frame 401 to move left and right in the liquid storage tank 1, so that the foam on the surface of the cutting fluid is collected into the inside of the collecting frame 401, thereby ensuring that the foam in the cutting fluid is collected, and avoiding inhaling a large amount of cutting fluid.

[0044] As Figure 1 Figure 8 ​As shown, embodiment two: because the foam part is attached to the side wall of the liquid tank 1, the adsorption of the foam is strong, so the existing suction head or the collection in embodiment one often cannot completely collect the foam attached to the surface, this embodiment is different from embodiment one in that the bottom of the connecting frame 5 is fixedly connected with a backplate 501, the backplate 501 is internally provided with an adsorption sponge 5012 for adsorbing the foam on the edge of the liquid tank 1; the outer side of the collection assembly 4 is provided with a squeezing piece, when the driving assembly 2 drives the collection assembly 4 to move through the fixed sliding block 3, the squeezing piece squeezes the adsorption sponge 5012 to absorb the foam.

The transmission rod (809) is fixedly connected to a second pulley (810) on the outside. The second pulley (810) and the first pulley (805) are connected by a belt drive.

3. A control system for a defoaming unit based on machine tool cutting fluid, applicable to a defoaming unit based on machine tool cutting fluid as described in any one of claims 1-2, characterized in that, The system includes a bubble detection sensor (12), a processor (13), and a comparison module (14). The output terminals of the liquid level sensor (6) and the bubble detection sensor (12) are connected to the input terminal of the processor (13). The processor (13) is connected to the comparison module (14). The output terminal of the processor (13) is connected to a controller (15). The controller (15) is connected to a first motor (205), a second motor (905), a suction pump (10), and a hydraulic telescopic rod (204), respectively.

4. A defoaming process based on machine tool cutting fluid, applicable to a defoaming unit based on machine tool cutting fluid as described in any one of claims 1-2, characterized in that: Includes the following steps: S1. The bubble detection sensor (12) detects the bubbles in the cutting fluid inside the storage tank (1). When foam appears, the hydraulic telescopic rod (204) is activated, which pushes the fixed slider (3). The fixed slider (3) pushes the connecting frame (5) and the collection assembly (4) to sink into the cutting fluid as a whole. S2. Then, the first motor (205) drives the collection component (4) to move on the surface of the cutting fluid in the storage tank (1) to collect the foam and part of the cutting fluid. At the same time, the adsorption sponge (5012) in the spiral plate (501) adsorbs the foam and cutting fluid on the side wall of the storage tank (1). S3. Finally, the foam in the collection component (4) and the adsorption sponge (5012) is sucked into the treatment component (9) by the suction pump (10), and then filtered by the crushing brush (903) inside the treatment component (9). The filtered cutting fluid is then reinjected into the storage tank (1).
