DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figure 1 to Figure 2 As shown, a cutting fluid oil-water separation and filtration system of the present invention comprises a controller and a collection box 1, wherein a filter plate 11 is fixedly connected between the inner walls of the collection box 1; the collection box 1 is connected to an oil-water separator through a water pump; an electric push rod 12 is fixedly connected to the outer side of the collection box 1; the piston rod of the electric push rod 12 penetrates the collection box 1 and is fixedly connected to a push plate 13; the push plate 13 is located above the filter plate 11; the area of ​​the bottom of the push plate 13 is smaller than the area of ​​the top of the push plate 13; a waste box 14 is fixedly connected to the collection box 1; the waste box 14 is away from the electric push rod 12 and is provided with a feed port 15 at a position corresponding to the push plate 13;

[0025] In the prior art, when the cutting fluid is filtered, the cutting fluid flows into the filtering system along with a large amount of chips, and the chips accumulate in the filtering system, causing the filtering system to be blocked, making the filtering system unable to be used normally, causing oil to overflow the filtering system, causing waste, and the oil that is difficult to clean will also pollute the production environment. In addition, the ground contaminated by oil can easily cause people to slip, leading to safety accidents.

[0026] According to the present invention, by setting a collection box 1, the cutting fluid discharged from the machine tool is discharged into the collection box 1, the filter plate 11 performs preliminary filtering on the chips in the cutting fluid, and the cutting fluid after preliminary filtration is pumped into the oil-water separator through a water pump for oil-water separation and then recycled, and the electric push rod 12 is controlled by the controller to start at a fixed time, and the electric push rod 12 drives the push plate 13 to push the chips accumulated on the filter plate 11 into the waste box 14 through the feed port 15. The area of ​​the bottom of the push plate 13 is small, so that the push plate 13 is prevented from being too much during the working process. The chips are stuck at the bottom of the push plate 13, resulting in an increase in the friction between the push plate 13 and the filter plate 11, thereby reducing the resistance of the push plate 13 during operation and preventing damage to the push plate 13 and the filter plate 11, thereby facilitating the collection of the chips and preventing a large amount of chips from accumulating on the filter plate 11 and causing blockage of the filter plate 11, thereby improving the stability of the working process of the filtration system, preventing oil pollution from overflowing, reducing damage to the production environment, preventing the occurrence of safety accidents, reducing the impact of chips during the oil-water separation process, and improving the efficiency and effect of oil-water separation.

[0027] As an embodiment of the present invention, the cross section of the filter plate 11 is arc-shaped; the push plate 13 is provided with an adjustment mechanism, and the adjustment mechanism includes a slide groove 21, a connecting block 22 and a spring 23; the bottom of the push plate 13 is provided with a slide groove 21; the slide groove 21 is slidably connected with a connecting block 22; the connecting block 22 is fixedly connected to the inner wall of the slide groove 21 with a spring 23; when working, by setting the arc-shaped filter plate 11, when filtering the cutting fluid, the filter residue can slide along the arc surface of the filter plate 11, so that the chips are accumulated on the filter plate 11. 1, so that the position where the filter plate 11 has no chip accumulation can still filter the cutting fluid, prevent the chips from clogging the filter plate 11, and improve the filtering effect of the filter plate 11 on the cutting fluid. When the controller controls the electric push rod 12 to start, the push plate 13 drives the connecting block 22 to move, and the connecting block 22 slides in the slide groove 21 under the elastic force of the spring 23, so that the connecting block 22 abuts against the upper surface of the filter plate 11 when following the push plate 13 to move, so that the connecting block 22 can push the chips into the waste box 14 along the curved surface of the filter plate 11.

[0028] As an embodiment of the present invention, the filter plate 11 is made of an elastic material; during operation, when the connecting block 22 abuts against the upper surface of the filter plate 11 and moves along the curved surface of the filter plate 11, the filter plate 11 made of the elastic material will vibrate with the movement and extrusion of the connecting block 22, so that the chips adhered to the filter plate 11 are loosened, thereby improving the cleaning effect of the connecting block 22 on the chips on the surface of the filter plate 11, preventing the chips from adhering to the filter plate 11, and preventing the filter plate 11 from being blocked.

[0029] As an embodiment of the present invention, an oil filter hole 24 is provided on the connecting block 22; during operation, by providing the oil filter hole 24, when the connecting block 22 pushes the chips, the cutting fluid mixed with the chips can pass through the oil filter hole 24, thereby reducing the resistance during the movement of the connecting block 22, reducing the content of the cutting fluid in the chips, thereby reducing the waste of the cutting fluid and improving the recovery value of the chips and the cutting fluid.

[0030] As an embodiment of the present invention, the push plate 13 corresponds to the size of the feed port 15; when working, the push plate 13 can enter the feed port 15 during its movement, so that the chips can be completely pushed into the waste box 14 from the feed port 15 by the push plate 13, preventing the chips from remaining at the feed port 15, so that the chips hinder the movement of the push plate 13, resulting in more chips accumulation and causing a vicious circle, thereby improving the chip cleaning effect, preventing chip accumulation, preventing the filter plate 11 from being blocked and causing oil to overflow, reducing damage to the production environment, preventing the occurrence of safety accidents, reducing the impact of chips in the oil-water separation process, and improving the efficiency and effect of oil-water separation.

[0031] As an embodiment of the present invention, the inner wall of the waste box 14 is fixedly connected with a cutter 3 at the feed port 15; when working, by setting the cutter 3, the push plate 13 pushes the strip-shaped chips and scraps to the cutter 3 when being pushed, so that the cutter 3 cuts the strip-shaped chips and scraps, thereby preventing the strip-shaped chips and scraps from being difficult to pass through the feed port 15 and causing the feed port 15 to be blocked, which is convenient for the subsequent oil-water separation processing of the chips and the recovery of the chips.

[0032] As an embodiment of the present invention, a drying barrel 4 is provided in the waste box 14; a drying hole 41 is provided on the drying barrel 4; a chip discharge port 42 is provided on the side of the drying barrel 4; a baffle 43 is slidably connected in the drying barrel 4; the baffle 43 corresponds to the position of the chip discharge port 42; when working, the chips are pushed into the drying barrel 4 by the push plate 13. Since the cutting fluid may be in a circulating process during the working process of the push plate 13, the cutting fluid content in the chips is relatively high. The cutting fluid mixed in the chips is filtered again through the drying hole 41 on the drying barrel 4, thereby reducing the content of the cutting fluid in the chips, thereby reducing the waste of the cutting fluid and improving the recovery value of the chips and the cutting fluid. When cleaning the chips in the drying barrel 4, the baffle 43 is pulled out to open the chip discharge port 42, and the chips in the drying barrel 4 are taken out through the chip discharge port 42.

[0033] As an embodiment of the present invention, a motor 44 is fixedly connected to the bottom of the waste box 14; the output shaft of the motor 44 passes through the waste box 14 and is fixedly connected to the drying barrel 4; when working, the motor 44 is started by the controller, so that the motor 44 drives the drying barrel 4 to rotate, so that the cutting fluid in the drying barrel 4 is quickly discharged from the drying hole 41 into the waste box 14 under the action of centrifugal force, thereby improving the drying efficiency and drying effect of the chips in the drying barrel 4, reducing the content of cutting fluid in the chips, thereby reducing the waste of cutting fluid, and improving the recovery value of chips and cutting fluid.

[0034] As an embodiment of the present invention, a door panel 5 leading into the waste box 14 is hinged on one side of the collection box 1 close to the waste box 14; an electromagnet 51 is fixedly connected to one side of the door panel 5 located in the collection box 1; during operation, when discharging chips in the drying barrel 4, the chip discharge port 42 is adjusted toward the door panel 5, the electromagnet 51 is started by the controller, and then the baffle 43 is pulled out to open the chip discharge port 42, so that the electromagnet 51 adsorbs the chips in the drying barrel 4, and then the door panel 5 is opened, and a container for recovering chips is placed under the door panel 5, and the controller controls the electromagnet 51 to be closed, so that the chips fall into the container for recovering chips, and the width of the chip discharge port 42 can be set to be larger than the radius of the drying barrel 4. At this time, the efficiency of chip collection can be improved, and the chips can be prevented from being blocked by the drying barrel 4, thereby facilitating manual collection of chips, reducing the labor of workers, preventing chips from cutting workers, and improving safety during operation.

[0035] As an embodiment of the present invention, the waste box 14 is connected with an air pipe 6; when working, one end of the air pipe 6 located in the waste box 14 faces the drying barrel, and the air pipe 6 is provided to connect the hot air source to the drying barrel 4 to pass hot air, thereby improving the drying efficiency and drying effect of the chips in the drying barrel 4, reducing the content of cutting fluid in the chips, and at the same time, when the compressed gas flows to the filter plate 11, it can also blow away the chips adhering to the filter plate 11 to prevent the filter plate 11 from being blocked.

[0036] The specific workflow is as follows:

[0037] The cutting fluid discharged from the machine tool is discharged into the collection box 1, and the filter plate 11 performs preliminary filtering on the chips in the cutting fluid. The cutting fluid after preliminary filtration is pumped into the oil-water separator through the water pump for oil-water separation and recycling. The electric push rod 12 is controlled by the controller to start at a fixed time, and the electric push rod 12 drives the push plate 13 to push the chips accumulated on the filter plate 11 into the waste box 14 through the feed port 15. By setting the arc-shaped filter plate 11, when filtering the cutting fluid, the filter residue can slide along the arc surface of the filter plate 11, so that the chips are accumulated in the low-lying part of the filter plate 11, so that the position of the filter plate 11 without chip accumulation can still filter the cutting fluid. When the controller controls the electric push rod 12 to start, the push plate 13 drives the connecting block 22 to move, and the connecting block 22 is elastic The spring 23 slides in the slide groove 21 under the elastic force of the spring 23, so that the connecting block 22 abuts against the upper surface of the filter plate 11 when following the movement of the push plate 13, so that the connecting block 22 can push the chips into the waste box 14 along the curved surface of the filter plate 11. When the connecting block 22 abuts against the upper surface of the filter plate 11 and moves along the curved surface of the filter plate 11, the filter plate 11 made of elastic material will vibrate with the movement and extrusion of the connecting block 22, so that the chips adhered to the filter plate 11 are loosened. By providing the oil filter hole 24, when the connecting block 22 pushes the chips, the cutting fluid mixed with the chips can pass through the oil filter hole 24, thereby reducing the resistance of the connecting block 22 during the movement, and reducing the content of the cutting fluid in the chips. During the movement of the push plate 13, the push plate 13 can enter the feed port 15. The chips can be completely pushed into the waste box 14 from the feed port 15 by the push plate 13, and the chips are prevented from remaining at the feed port 15, so that the chips hinder the movement of the push plate 13, resulting in more accumulation of chips and causing a vicious cycle. By setting the cutter 3, the push plate 13 pushes the strip-shaped chips and scraps to the cutter 3 when pushing, so that the cutter 3 cuts the strip-shaped chips and scraps, thereby preventing the strip-shaped chips and scraps from being difficult to pass through the feed port 15 and causing the feed port 15 to be blocked, which is convenient for the subsequent oil-water separation of the chips and the recovery of the chips. The chips are pushed into the drying barrel 4 by the push plate 13. Since the cutting fluid may be in a circulating working process during the working process of the push plate 13, the cutting fluid content in the chips is relatively high, and the chips are dried on the drying barrel 4. The hole 41 filters the cutting fluid mixed in the chips again, and the controller controls the motor 44 to start, so that the motor 44 drives the drying barrel 4 to rotate, so that the cutting fluid in the drying barrel 4 is quickly discharged from the drying hole 41 under the action of centrifugal force. When discharging the chips in the drying barrel 4, the chip discharge port 42 is adjusted to face the door panel 5, and the controller controls the electromagnet 51 to start, and then the baffle 43 is pulled out to open the chip discharge port 42, so that the electromagnet 51 adsorbs the chips in the drying barrel 4, and then the door panel 5 is opened, and the container for recovering chips is placed under the door panel 5. The controller controls the electromagnet 51 to close, so that the chips fall into the container for recovering chips, and the air pipe 6 is set to pass compressed gas to the drying barrel 4 through the air pipe 6 to reduce the content of cutting fluid in the chips.At the same time, when the compressed gas flows to the filter plate 11, the chips adhering to the filter plate 11 can also be blown away.
