Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, and discloses an oil-water separator for a numerical control machine tool. Background Technique

[0002] A numerical control machine tool is an automated machine tool equipped with a program control system. This control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, input it into the numerical control device through an information carrier, and after arithmetic processing, the numerical control device issues various control signals to control the operation of the machine tool. The numerical control machine tool has better solved the problems of processing complex, precise, small-batch, and multi-variety parts. It is a flexible and high-efficiency automated machine tool. When a numerical control machine tool is working, an oil-water separator is required. Modern oil-water separators for numerical control machine tools have become increasingly mature and can perform oil-water separation on the oil stains generated during the processing of numerical control machine tools.

[0003] The patent with the patent number CN212523115U in the prior art introduces an oil-water separator for a numerical control machine tool, including a collection box. A lead screw is vertically installed on the top surface of the collection box, and one end of the lead screw penetrates through the top surface of the collection box and extends into the interior of the collection box. In the utility model, a lead screw is vertically installed on the top of the collection box, and one end of the lead screw penetrates through the surface of the collection box and extends into the interior. An oil suction pipe is installed at the bottom end of the collection box through a fixed clamp, and one end of the oil suction pipe is connected to a suction pump through a drain pipe. Through the combined use of the suction pump and the oil suction pipe, it is convenient to adsorb the oil floating on the surface of the collection box. This method changes the traditional method of scraping with a scraper, greatly improving the working efficiency. Secondly, a threaded sleeve is sleeved on the surface of the lead screw. The threaded sleeve is meshed with a gear through the teeth on the surface, and one end of the gear is connected to the output end of the stepping motor through a transmission shaft. Through the combined use of the lead screw, the threaded sleeve, the teeth, and the gear, it is convenient to adjust the depth of the oil suction pipe inside the collection box.

[0004] However, the patents in the prior art have the following several disadvantages:

[0005] (1) When the patents in the prior art are in use, the waste water may be mixed with some sundries, which will affect the oil-water separation.

[0006] (2) When the patents in the prior art are in use, there will still be a small amount of oil in the remaining waste water that cannot be sucked, resulting in incomplete oil-water separation. Content of the Utility Model

[0007] The technical problem to be solved by the utility model is to overcome the above technical defects and provide an oil-water separator for a numerical control machine tool that can not only filter sundries but also achieve more thorough oil-water separation.

[0008] To solve the above technical problems, the present utility model provides the following technical solutions: An oil-water separator for a numerical control machine tool, comprising an oil-water separation tank. The left end of the oil-water separation tank is connected to a feed pipe, and the upper end of the feed pipe is provided with a feed port. A magnet plate is arranged inside the feed pipe. A window is provided on the right end surface of the oil-water separation tank. Slide rails are provided on both the front and rear sides of the right end of the window. A filter box is slidably connected inside the window, and a filter screen is arranged inside the filter box. A drain pipe is provided at the bottom of the oil-water separation tank. A door plate is rotatably connected to the front end of the oil-water separation tank. A handle is provided on the front end surface of the door plate, and a sealing rubber ring is provided on the rear end surface of the door plate. A water pump is provided at the upper end of the oil-water separation tank. An oil suction hose is provided at the left end of the water pump, and an oil suction cover is provided at the bottom end of the oil suction hose. An oil storage tank is provided on the right side of the oil-water separation tank, and an oil delivery pipe is provided between the oil storage tank and the water pump. A lifting device is provided above the interior of the oil-water separation tank, and an oil suction device is provided at the bottom side of the interior of the oil-water separation tank.

[0009] Further, the lifting device comprises a first screw rod. A first motor is provided at the upper end of the first screw rod. The first screw rod is rotatably connected to the oil-water separation tank. A sliding shaft is provided on one side of the first screw rod, and the upper end of the sliding shaft is fixedly connected to the oil-water separation tank.

[0010] Further, a slider is sleeved on the surface of the sliding shaft. The left end of the slider is threadedly connected to the first screw rod, and the right end of the slider is fixedly connected to the oil suction hose. A limit ring is provided at the bottom end of the first screw rod.

[0011] Further, the oil suction device comprises a second screw rod. A second motor is provided at the left end of the second screw rod. The second screw rod is rotatably connected to the oil-water separation tank. A sliding rod is provided on one side of the second screw rod, and both ends of the sliding rod are fixedly connected to the oil-water separation tank.

[0012] Further, a cross plate is sleeved on the surface of the sliding rod. The cross plate is threadedly connected to the second screw rod. A convex platform is provided on the right end surface of the cross plate, and a stud is threadedly connected inside the convex platform.

[0013] Further, a knob is provided at the right end of the stud. A clamping plate is rotatably connected to the left end of the stud. An oil absorption cotton plate is provided between the clamping plate and the cross plate.

[0014] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0015] (1) By setting a magnet plate and a filter box, the present utility model solves the problem that the existing oil-water separator for a numerical control machine tool cannot remove sundries. When the waste water passes through the feed pipe, the metal substances in the waste water will be adsorbed by the magnet plate. When the waste water passes through the filter box, the non-metal sundries will be filtered out by the filter screen, preventing the sundries from affecting the oil-water separation.

[0016] (2) By setting up an oil absorption device, the utility model solves the problem of incomplete separation of the existing oil-water separator for CNC machine tools. After the water pump finishes sucking the oil, starting the second motor can drive the second screw rod to rotate, causing the horizontal plate to move horizontally, and then the oil absorption cotton plate to move, so as to adsorb the oil floating on the water surface cleanly, achieving a better oil-water separation effect.

There is an oil storage tank 7 on the right side of the oil-water separation tank 1 for storing oil liquid. There is an oil delivery pipe 403 between the oil storage tank 7 and the water pump 4. The water pump 4 can transport the sucked oil liquid to the oil storage tank 7 through the oil delivery pipe 403. There is a lifting device 5 above the inside of the oil-water separation tank 1, which can control the height of the oil suction cover 402. There is an oil absorption device 6 at the bottom side inside the oil-water separation tank 1, which can adsorb the residual oil liquid.

[0025] Specifically, the oil absorption device 6 includes a second screw rod 601. There is a second motor 602 at the left end of the second screw rod 601. The second motor 602 can control the rotation of the second screw rod 601. The second screw rod 601 is rotatably connected to the oil-water separation tank 1. There is a slide rod 603 on one side of the second screw rod 601. Both ends of the slide rod 603 are fixedly connected to the oil-water separation tank 1. A cross plate 604 is sleeved on the surface of the slide rod 603. The cross plate 604 is threadedly connected to the second screw rod 601. The cross plate 604 will move on the slide rod 603 as the second screw rod 601 rotates. There is a boss 605 on the right end surface of the cross plate 604.

[0026] Through the above technical solution, after the water pump 4 finishes sucking the oil, starting the second motor 602 can drive the second screw rod 601 to rotate, causing the cross plate 604 to move in the horizontal direction, and then causing the oil-absorbing cotton plate 609 to move, adsorbing the oil floating on the water surface cleanly, and achieving a better oil-water separation effect.

[0027] Specifically, the lifting device 5 includes a first screw rod 501. There is a first motor 502 at the upper end of the first screw rod 501, which can control the rotation of the first screw rod 501. The first screw rod 501 is rotatably connected to the oil-water separation tank 1. There is a sliding shaft 503 on one side of the first screw rod 501.

[0028] Through the above technical solution, the first motor 502 can control the rotation of the first screw rod 501, causing the slider 504 to move in the vertical direction and thus changing the height of the oil suction cover 402, facilitating oil suction following the height of the wastewater.

[0029] During use, the wastewater passes through the feed pipe 101, and the metal substances in the wastewater are adsorbed by the magnet plate 103. Subsequently, the wastewater passes through the filter box 2, and the non-metallic sundries are filtered out by the filter net 201. The water pump 4 is started. The water pump 4 sucks the floating oil through the oil suction cover 402, and then conveys the sucked oil liquid to the storage oil tank 7 through the oil delivery pipe 403. The first motor 502 can control the rotation of the first screw rod 501, causing the slider 504 to move in the vertical direction and thus changing the height of the oil suction cover 402, facilitating oil suction following the height of the wastewater. After the water pump 4 finishes sucking the oil, the second motor 602 is started to drive the second screw rod 601 to rotate, causing the cross plate 604 to move in the horizontal direction, and then causing the oil-absorbing cotton plate 609 to move, adsorbing the oil floating on the water surface cleanly, and achieving a better oil-water separation effect.
