During the processing, in order to reduce the temperature of the tool and the workpiece and reduce friction and wear, coolant or lubricant is usually used, resulting in a large amount of oil impurities on the tool.

[0003] However, when cleaning the tool in the prior art, after the cleaning step, the impurities and oil in the cleaning agent are mostly filtered physically. However, the pore sizes of the existing filter materials may vary greatly. Some pore sizes are too large, so that the oil impurities and bacteria with a diameter greater than 1nm cannot be effectively intercepted; while some pore sizes are too small, which will hinder the passage of cleaning agent molecules and reduce the filtration efficiency. In addition, the uneven distribution of pore sizes will also cause the flow speed of the cleaning agent to be unstable during the filtration process. The flow speed in some areas is too fast, and the cleaning agent passes through before it can be fully filtered; while the flow speed in some areas is too slow, which is easy to cause the accumulation of oil impurities, further blocking the filter holes, affecting the durability of the filtration effect, and thus failing to achieve a full separation of the cleaning agent and oil impurities.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the present invention provides a technical solution: a cleaning agent recycling system, comprising a filter tank 1, wherein a filter structure 2 is arranged inside the filter tank 1; A pressure structure 3 is provided above the filter tank 1; The outer side wall of the filter tank body 1 is provided with a support structure 5; The filtering structure 2 includes a ceramic filter plate 201 fixedly connected to the inner wall of the filtering tank body 1, and ultra-micropores are evenly opened on the ceramic filter plate 201, and the pore size of the ultra-micropores is less than or equal to 1nm. Since the diameter of the cleaning agent molecule is less than 1nm, and the diameter of the oil, impurities, bacteria and the like cleaned by the tool is greater than 1nm, the ultra-micropores arranged on the ceramic filter plate 201 can effectively filter the cleaning agent molecules, and the bottom of the ceramic filter plate 201 is fixedly connected with an arc-shaped protrusion 202, and the bottom center of the ceramic filter plate 201 is fixedly connected with a fixed column 203, and the outer wall of the fixed column 203 is rotatably connected with a turbine fan 204, and the top of the turbine fan 204 is fixedly connected with a support rod 205, and four support rods 205 are arranged, and the four support rods 205 are distributed in a circular array. At the top of the turbine fan 204, the ends of the four support rods 205 close to the turbine fan 204 are respectively hinged with inclined rods 206, and the outer side walls of the four inclined rods 206 are respectively provided with limiting grooves 207, and the ends of the four inclined rods 206 away from the turbine fan 204 are respectively fixedly connected with hemispheres 208, and the tops of the four hemispheres 208 are all fitted with the bottom of the ceramic filter plate 201, and the tops of the four support rods 205 are respectively fixedly connected with columns 209, and the tops of the support rods 205 are fixedly connected with springs 210, and the ends of the springs 210 away from the support rods 205 are provided with sliders, and the tops of the sliders are fitted with the bottoms of the inclined rods 206, and the inner side wall of the filter tank body 1 is fixedly connected with a snap ring 211, and the end of the support rod 205 close to the snap ring 211 is rotatably connected with a roller 212; After the mixed liquid enters the interior of the filter tank body 1, the used cleaning agent is filtered by the ceramic filter plate 201. At this time, the back-blowing device blows high-pressure gas into the interior of the filter tank body 1. At this time, the turbine fan 204 rotates under the influence of wind force, thereby driving the four support rods 205 to rotate synchronously. In addition, because four arc-shaped protrusions 202 are provided at the bottom of the ceramic filter plate 201, when the top of the hemispherical body 208 fixed at one end of the four inclined rods 206 conflicts with the outer side walls of the four arc-shaped protrusions 202, the four inclined rods 206 are forced to move toward The four support rods 205 move in the same direction, thereby compressing the four springs 210. When the four hemispheres 208 gradually move away from the four arc-shaped protrusions 202, under the action of the elastic force of the four springs 210 themselves, the four inclined rods 206 will drive the four hemispheres 208 to knock on the bottom of the ceramic filter plate 201, causing the ceramic filter plate 201 to vibrate. The vibration will make the movement of the oil molecules more chaotic. They may continuously collide and gather on the surface of the filter plate, or be loosened by the vibration and more easily carried away by the backblowing gas.

[0025] like Figure 6 , Figure 7 As shown: the pressure structure 3 includes a slide bar 301 fixedly connected to the top of the filter tank body 1, the outer wall of the slide bar 301 is slidably connected to a moving plate 302, the bottom of the moving plate 302 is fixedly connected to a motor 303, the output end of the motor 303 is fixedly connected to a threaded rod 304, the outer wall of the threaded rod 304 is threadedly connected to the top of the filter tank body 1, and the end of the threaded rod 304 away from the motor 303 is rotatably connected to a rubber block 305, and the outer wall of the rubber block 305 is in contact with the inner wall of the filter tank body 1; When in use, the motor 303 is started, and the motor 303 drives the threaded rod 304 to rotate. When the threaded rod 304 rotates, since the threaded rod 304 is threadedly connected to the top of the filter tank body 1, the rotation of the threaded rod 304 will move the movable plate 302 and the motor 303 toward the filter tank body 1. Because the end of the threaded rod 304 away from the motor 303 is rotatably connected to the rubber block 305, when the threaded rod 304 rotates and changes its position, it will push the rubber block 305 to move toward the bottom of the filter tank body 1. At this time, the movement of the rubber block 305 will compress the air inside the filter tank body 1, especially the air above the ceramic filter plate 201 inside the filter tank body 1, thereby increasing the filtration speed of the impurity mixture above the ceramic filter plate 201.

[0026] like Figure 6 , Figure 7As shown: the outer wall of the rubber block 305 is provided with a mounting groove 306, and the inner wall of the rubber block 305 is fixedly connected to a limiting rod 307, two limiting rods 307 are provided, and the two limiting rods 307 are both located inside the mounting groove 306, and the outer walls of the two limiting rods 307 are slidably connected to a baffle 309, and the top of the baffle 309 is fixedly connected to a return spring 308, and two return springs 308 are also provided, and the two return springs 308 are respectively wound around the outside of the two limiting rods 307. When in use, as the rubber block 305 moves toward the bottom direction of the filter tank body 1, the baffle 309 will be driven to move synchronously. When the baffle 309 moves to the connection point of the feed pipe 4, the baffle 309 stops, and the rubber block 305 continues to move. The fixed connection between the baffle plate 309 and the return spring 308 slides along the two limit rods 307, so that the rubber block 305 can continue to move, thereby further compressing the air inside the filter tank body 1. A slot 310 is provided on the inner wall of the filter tank body 1, and the slot 310 is located at the connection point between the filter tank body 1 and the feed pipe 4. The baffle plate 309 is engaged with the filter tank body 1 through the slot 310, and the outer wall of the baffle plate 309 is matched with the slot 310, which is convenient for limiting the position of the baffle plate 309 and preventing the baffle plate 309 from blocking the moving path of the rubber block 305 when it is stagnant. When the baffle plate 309 is inserted into the slot 310, the outer wall of the baffle plate 309 is matched with the inner wall of the filter tank body 1, so that the rubber block 305 can continue to move.

[0027] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown: the outer wall of the filter tank body 1 is fixedly connected with a feed pipe 4, the feed pipe 4 is located at the slot 310, and one end of the feed pipe 4 is located above the ceramic filter plate 201; like Figure 1 , Figure 2 and Figure 3 As shown: the outer wall of the filter tank body 1 is fixedly connected with a back-blowing pipe 6, and a pressurizing mechanism is arranged at one end of the back-blowing pipe 6 away from the filter tank body 1. When the high-performance ceramic filter plate 2 needs to be back-blown, the air is pressurized by the pressurizing mechanism, and then the pressurized airflow is transmitted to the interior of the filter tank body 1 through the back-blowing pipe 6 to back-blow the high-performance ceramic filter plate 2 to prevent oil and impurities from clogging the micropores opened on the high-performance ceramic filter plate 2. The back-blowing pipe 6 is located at one end of the interior of the filter tank body 1 below the high-performance ceramic filter plate 2 and is on the same vertical line as the center point of the high-performance ceramic filter plate 2. When the airflow enters the interior of the filter tank body 1, it is blown from the bottom of the high-performance ceramic filter plate 2 to the top of the high-performance ceramic filter plate 2. Because the back-blowing pipe 6 is located at the center of the bottom of the high-performance ceramic filter plate 2, the high-pressure airflow can be evenly distributed to the bottom of the high-performance ceramic filter plate 2 to avoid the back-blowing position being concentrated, resulting in incomplete cleaning. like Figure 1 , Figure 2 As shown: one end of the backflush pipe 6 located inside the filter tank 1 is below the ceramic filter plate 201 and is on the same vertical line as the center point of the ceramic filter plate 201. like Figure 1 , Figure 2 As shown: the support structure 5 includes an annular guardrail 501 fixedly connected to the outer wall of the filter tank body 1, and the outer wall of the annular guardrail 501 is fixedly connected to a bracket 502 like Figure 1 , Figure 2 As shown: the bottom of the filter tank body 1 is fixedly connected with a reflux pipe 7, which is located at the bottom center of the filter tank body 1. A valve 71 is provided on the reflux pipe 7 to facilitate the recovery and reuse of the recyclable detergent inside the filter tank body 1.

[0028] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, when the cleaning agent recycling system is in use, the mixed detergent enters the interior of the filter tank body 1 through the feed pipe 4, and the motor 303 is further started, and the motor 303 drives the threaded rod 304 to rotate. When the threaded rod 304 rotates, since the threaded rod 304 is threadedly connected to the top of the filter tank body 1, the rotation of the threaded rod 304 will move the moving plate 302 and the motor 303 toward the filter tank body 1. Because the end of the threaded rod 304 away from the motor 303 is rotatably connected to the rubber block 305, when the threaded rod 304 rotates and changes its position, it will push the rubber block 305 to pass through. The bottom of the filter tank body 1 moves, and the movement of the rubber block 305 at this time will compress the air inside the filter tank body 1, especially the air above the high-performance ceramic filter plate 2 inside the filter tank body 1, thereby increasing the air pressure above the high-performance ceramic filter plate 2. The high-performance ceramic filter plate 2 is provided with ultra-micropores, and the ultra-micropore pore size is less than or equal to 1nm. Since the diameter of the cleaning agent molecule is less than 1nm, and the diameter of the oil, impurities, bacteria, etc. cleaned by the tool is greater than 1nm, the ultra-micropores provided on the high-performance ceramic filter plate 2 can effectively filter the cleaning agent molecules. Since the molecular diameter of the oil impurities is generally The particles larger than 1 nm are intercepted by the high-performance ceramic filter plate 2 during filtration, thereby filtering and recovering the detergent. When the air above the high-performance ceramic filter plate 2 is compressed, the filtration speed of the impurity mixture above the high-performance ceramic filter plate 2 is increased. After the filtration is completed, 6 is started to blow high-pressure gas into the interior of the filter tank 1. At this time, the turbine fan 204 rotates under the influence of wind force, thereby driving the four support rods 205 to rotate synchronously. In addition, because four arc-shaped protrusions 202 are arranged at the bottom of the ceramic filter plate 201, when the top of the hemispherical body 208 fixed by one end of the four inclined rods 206 and the four When the outer wall of the arc-shaped protrusion 202 collides, the four inclined rods 206 are forced to move toward the direction of the four support rods 205, thereby compressing the four springs 210. When the four hemispheres 208 gradually move away from the four arc-shaped protrusions 202, under the action of the elastic force of the four springs 210 themselves, the four inclined rods 206 will drive the four hemispheres 208 to knock on the bottom of the ceramic filter plate 201, causing the ceramic filter plate 201 to vibrate. The vibration will make the movement of the oil molecules more chaotic. They may continue to collide and gather on the surface of the filter plate, or be loosened by the vibration and more easily carried away by the backblowing gas.
