Description

Technical Field

[0001] This utility model relates to the field of separation device technology, specifically to a device for separating cutting fluid debris from a large grinding machine. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. It is made of a variety of high-performance additives through scientific compounding and has good cooling performance, lubrication performance, rust prevention performance, degreasing and cleaning function, anti-corrosion function, and easy dilution characteristics.

[0003] Currently, the common method for separating cutting fluid is to place the generated chips in a static location and allow them to separate naturally by gravity. However, this method is not very efficient, and the size of impurities such as iron filings in the cutting fluid varies, making it impossible for traditional separation devices to completely separate them.

[0004] The prior art discloses a patent number CN210255749U, which includes a chassis, a controller on the surface of the chassis, the controller being fixedly connected to the chassis by bolts, a housing on the top of the chassis, a dual-axis motor on the upper part of the housing, a roller shaft below the dual-axis motor, and oscillators on both sides inside the chassis. This is a spiral extrusion mill cutting fluid purification and separation device. The cutting fluid flows into a holding tank, and the drive motor is started to drive the drive shaft to rotate, causing the holding tank to rotate. Through the action of centrifugal force, the cutting fluid is thrown out of the holding tank. The cutting fluid is separated again through a secondary screen, with impurities remaining in the holding tank and the cutting fluid flowing into a collection tank, completing the separation process. This setup performs multiple separations on cutting fluid containing iron filings, and can filter out iron filings of different sizes, improving the separation quality of the cutting fluid.

[0005] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0006] First, during the machining process of a large grinding machine, a large amount of iron dust is generated. This iron dust is easily mixed into the cutting fluid, which can clog the nozzle when the cutting fluid is reused, thus affecting the machining quality of the workpiece.

[0007] Secondly, in existing powder separation devices, the iron fragments tend to accumulate inside the device after separation, making it difficult to remove them and increasing the cleaning difficulty for operators.

[0008] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a cutting fluid debris separation device for large grinding machines. This device solves the problems of iron debris easily getting mixed into the cutting fluid, causing the nozzle to clog during reuse and affecting the workpiece processing quality; and iron debris easily accumulating in the separation device, making it difficult to remove and increasing the cleaning difficulty for operators.

[0010] To achieve the above objectives, the present invention provides the following technical solution.

[0011] A cutting fluid debris separation device for a large grinding machine includes a collection tank and a recovery tank arranged side by side. An overflow plate is fixedly connected inside the collection tank, dividing the collection tank into an overflow zone and a separation zone. The overflow zone is connected to the recovery tank.

[0012] The collection tank has a mounting hole at the bottom of one end of the separation zone, which is located above the recovery tank. A magnetic roller is rotatably mounted inside the mounting hole, with its lower surface below the mounting hole. A water-driving roller that rubs against the magnetic roller's peripheral wall is positioned above the magnetic roller and moves up and down.

[0013] The collection trough is located at the end opening of the separation zone and is hinged to a swinging scraper. The upper end of the scraper rubs against the peripheral wall of the magnetic roller, and a debris collection trough is movably provided below the lower end of the scraper.

[0014] As an optimized solution, two guide plates are fixedly attached in a tapered manner on the bottom surface of the separation zone near the mounting hole, and the outlet width between the two guide plates is smaller than the width of the magnetic roller.

[0015] As an optimized solution, the water-driving roller is located on one side of the centerline of the magnetic roller and close to the overflow plate.

[0016] As an optimized solution, guide posts are obliquely fixed to the top of opposite side walls of the collection tank, and a slider is slidably connected to each guide post. The two ends of the water-driving roller are rotatably mounted on the opposite inner walls of the two sliders.

[0017] As an optimized solution, the upper end of the guide post is provided with an external thread section, and a nut is threadedly connected to the thread section. A compression spring is fitted on the guide post, and the two ends of the compression spring abut against the nut and the slider, respectively.

[0018] As an optimized solution, the width of the scraper is greater than the width of the magnetic roller, and guide plates are fixedly attached to the upper surface of the scraper near the opposite sidewall.

[0019] As an optimized solution, an arc-shaped adjustment groove is provided on the side wall of the collection tank, and a screw is fixedly connected to the side wall of the scraper and slidably constrained in the arc-shaped adjustment groove. A locking nut is threaded onto the screw, and the side wall of the locking nut rubs against the outer wall of the collection tank.

[0020] As an optimized solution, the lower end of the debris collection trough is fixedly connected with moving wheels in parallel.

[0021] As an optimized solution, the bottom of the overflow area is fixedly connected to an outlet cylinder that communicates with the recovery tank.

[0022] As an optimized solution, a drain cylinder communicating with its inner cavity is fixedly connected to the bottom of the recovery tank.

[0023] As an optimized solution, the collection tank is equipped with a liquid inlet cylinder above the separation zone.

[0024] As an optimized solution, a speed reducer for driving the magnetic roller to rotate is fixed to the outer wall of the collection tank.

[0025] As an optimized solution, the collection trough is fixedly connected to a bracket, and the lower surface of the scraper is hinged to the bracket via a hinge seat.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] The liquid-debris mixture enters the separation zone through the liquid inlet cylinder connected to the liquid outlet of the large grinding machine. After the debris falls to the bottom of the separation zone, the liquid enters the overflow zone through the overflow plate and then enters the recovery tank through the liquid outlet cylinder for reuse.

[0028] The liquid mixture in the separation zone carries debris toward the mounting hole, and the liquid flows through the mounting hole into the recovery tank; while the debris is attracted by the magnetic roller and adheres to the surface of the magnetic roller to perform the adsorption and separation of iron filings.

[0029] A water-repelling roller is installed above the magnetic roller, which removes the liquid adhering to the debris, further separating the liquid from the debris. The debris adheres to the magnetic roller, and as the magnetic roller rotates, it carries the debris into the area where the scraper is located. Due to the friction between the scraper and the magnetic roller, the debris is scraped off. The scraped debris is guided by the scraper and slides into the debris collection trough. By flexibly moving the debris collection trough, the iron filings can be transferred, which is convenient and quick, reduces the labor intensity of operators, and improves the cleaning efficiency of iron filings.

Detailed Implementation

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0035] like Figure 1 and Figure 2 As shown, the cutting fluid debris separation device for a large grinding machine includes a collection tank 1 and a recovery tank 2 arranged side by side. An overflow plate 4 is fixedly connected inside the collection tank 1, and the overflow plate 4 divides the collection tank 1 into an overflow zone 6 and a separation zone 5. The overflow zone 6 is connected to the recovery tank 2.

[0036] A mounting hole 10 is provided at the bottom of one end of the collection tank 1, which is located above the recovery tank 2. A magnetic roller 12 is rotatably installed inside the mounting hole 10. The lower surface of the magnetic roller 12 is lower than the mounting hole 10. A water-driving roller 13 is raised and lowered above the magnetic roller 12, which is in frictional contact with its peripheral wall.

[0037] The collection trough 1 is located at the end opening of the separation zone 5 and is hinged to a swinging scraper 18. The upper end of the scraper 18 rubs against the peripheral wall of the magnetic roller 12, and the lower end of the scraper 18 is movably provided with a debris collection trough 3.

[0038] Two guide plates 11 are fixedly attached to the bottom surface of the separation zone 5 near the mounting hole 10 in a tapering manner. The outlet width between the two guide plates 11 is smaller than the width of the magnetic roller 12, so as to gather the liquid and iron filings and prevent them from entering the gap between the end wall of the magnetic roller 12 and the inner wall of the collection tank 1.

[0039] The water-driving roller 13 is located on one side of the centerline of the magnetic roller 12 and close to the overflow plate 4, so as to allow the squeezed liquid to enter the separation zone 5 instead of the scraper 18 side.

[0040] Guide posts 14 are fixedly and inclinedly connected to the top of opposite side walls of the collection tank 1. A slider 15 is slidably connected to each guide post 14. The two ends of the water-driving roller 13 are rotatably installed on the opposite inner walls of the two sliders 15.

[0041] The upper end of the guide post 14 is provided with an external thread section, and a nut is threadedly connected to the thread section. A compression spring 17 is fitted on the guide post 14. The two ends of the compression spring 17 abut against the nut and the slider 15 respectively, so as to adjust the clamping force of the water-driving roller 13.

[0042] The width of the scraper 18 is greater than the width of the magnetic roller 12, and guide plates 19 are fixedly attached to the upper surface of the scraper 18 near the opposite side wall.

[0043] An arc-shaped adjustment groove 22 is provided on the side wall of the collection tank 1. A screw 20 is fixedly connected to the side wall of the scraper 18 and slidably constrained in the arc-shaped adjustment groove 22. A locking nut is threaded on the screw 20. The side wall of the locking nut rubs against the outer wall of the collection tank 1, so that when the gap at the upper end of the scraper 18 increases due to friction, the upper end of the scraper 18 can be swung to make it contact the magnetic roller 12, thereby improving the cleaning efficiency of iron filings.

[0044] The lower end of the debris collection trough 3 is fixed with moving wheels in parallel.

[0045] The bottom of the overflow area 6 is fixedly connected to the liquid outlet cylinder 8, which is connected to the recovery tank 2.

[0046] The bottom of the recovery tank 2 is fixedly connected to a drain cylinder 9 that communicates with its inner cavity.

[0047] The collection tank 1 is located above the separation zone 5 and is equipped with an inlet cylinder 7.

[0048] A reducer 23 that drives the magnetic roller 12 to rotate is fixed to the outer wall of the collection tank 1.

[0049] The collection tank 1 is fixedly connected to a bracket, and the lower surface of the scraper 18 is hinged to the bracket via a hinge seat.

[0050] The collection tank 1 and the recycling tank 2 are fixedly supported by the frame. Since this is not an innovative feature of this solution, it will not be described in detail here.

[0051] The working principle of this device is as follows:

[0052] The liquid-debris mixture enters the separation zone 5 through the liquid inlet cylinder 7 connected to the liquid outlet of the large grinding machine. After the debris falls to the bottom of the separation zone 5, the liquid enters the overflow zone 6 through the overflow plate 4 and enters the recovery tank 2 through the liquid outlet cylinder 8 for reuse.

[0053] The liquid mixture located in the separation zone 5 carries debris toward the mounting hole 10, and the liquid flows through the mounting hole 10 into the recovery tank 2; while the debris, when passing through the mounting hole 10, is attracted by the magnetic roller 12 and adheres to the surface of the magnetic roller 12 to perform the adsorption and separation of iron filings.

[0054] A water-repelling roller 13 is provided above the magnetic roller 12 and is in contact with it. This removes the liquid adhering to the debris, further separating the liquid from the debris. The debris adheres to the magnetic roller 12. As the magnetic roller 12 rotates, it carries the debris into the area where the scraper 18 is located. Due to the friction between the scraper 18 and the magnetic roller 12, the debris is scraped off. The scraped debris is guided by the scraper 18 and slides into the debris collection trough 3. By flexibly moving the debris collection trough 3, the iron filings can be transferred, which is convenient and quick, reduces the labor intensity of operators, and improves the cleaning efficiency of iron filings.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
