Description

Technical Field

[0001] This application relates to the field of liquid purification and treatment, and more particularly to metal cutting waste liquid purification and treatment technology, specifically to a metal cutting waste liquid treatment device. Background Technology

[0002] Metal cutting fluid is a liquid used in metal processing, mainly for cooling, lubrication, and cleaning of the working area. It is widely used in various metal processing techniques such as turning, milling, drilling, and grinding. It can not only improve processing efficiency and workpiece quality, but also extend tool life and help protect the safety of machine tools and operators.

[0003] Metal cutting fluid that cannot be used after deterioration or contamination is called metal cutting waste fluid. Metal cutting waste fluid containing too many pollutants must be treated to meet discharge standards before it can be discharged. Therefore, metal waste fluid treatment equipment is needed to remove metal impurities, waste oil, etc. from the waste fluid.

[0004] Common metal waste liquid treatment equipment generally purifies metal waste liquid through filtration and oil-water separation. However, the purification effect is not good, and multiple treatments are required to meet the discharge requirements. Moreover, because metal waste liquid contains sharp metal impurities generated from cutting, it is easy to cause filter screen blockage and wear during filtration, affecting the filtration effect and requiring constant filter screen replacement, resulting in low purification efficiency. Summary of the Invention

[0005] To address the aforementioned deficiencies in existing technologies, this application provides a metal cutting waste liquid purification and treatment device that can improve the purification effect and efficiency, and has strong practicality.

[0006] To achieve the above objectives, the present invention employs the following techniques:

[0007] A metal cutting waste fluid purification and treatment device, comprising:

[0008] The primary treatment chamber has a rotating plate that rotates coaxially on its lower inner surface. Multiple magnetic rods are vertically arranged on the upper surface of the rotating plate. A lifting ring is coaxially movable on the inner wall of the primary treatment chamber. A rotating disk is coaxially rotated on the inner side of the lifting ring. Multiple lifting channels through which the magnetic rods pass are connected are arranged. A circular opening is coaxially through the upper surface of the primary treatment chamber. The outer wall of the primary treatment chamber has a first water pipe with two ends connected to the upper and lower ends of the side wall of the primary treatment chamber respectively. A first valve is installed on the first water pipe.

[0009] The secondary processing chamber has multiple chambers located below the central axis of the primary processing chamber, arranged in a circular array around the central axis. A second water pipe connects the lower surface of the secondary processing chamber to the primary processing chamber. A second valve is installed on each of the second water pipes. The lower end of each secondary processing chamber is open.

[0010] The intermediate ring has multiple rings that are movable parallel to the central axis and whose number matches that of the secondary processing chamber. They are arranged in a circular array that matches the secondary processing chamber and rotate around the central axis. The inner wall of the intermediate ring matches the outer wall of the secondary processing chamber. The inner wall of the intermediate ring is coaxially provided with a mounting ring for loading a filter screen.

[0011] The three-stage treatment chambers are located below the middle ring and are matched in number and size to the two-stage treatment chambers. They are moved coaxially with the two-stage treatment chambers. Each of the three-stage treatment chambers is connected to a third water pipe, and a third valve is installed on the third water pipe. The upper part of each of the three-stage treatment chambers is open.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. By setting up a primary treatment chamber, a secondary treatment chamber, an intermediate ring, and a tertiary treatment chamber, it is possible to first treat metallic impurities and then treat other impurities, thus achieving multi-stage purification treatment of metal cutting waste fluid and improving the purification effect of metal cutting waste fluid.

[0014] 2. The magnetic suction rod in the primary treatment chamber first removes metal impurities, preventing them from clogging or damaging the filter screen, reducing the frequency of filter cleaning and replacement, and improving the purification efficiency of metal cutting waste fluid.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0027] like Figure 1 As shown in the figure, this embodiment provides a metal cutting waste liquid purification and treatment device, including a primary treatment chamber 1, a secondary treatment chamber 2, an intermediate ring 3, and a tertiary treatment chamber 4.

[0028] Specifically, such as Figure 2As shown, a rotating plate 11 is coaxially rotatable on the lower surface of the primary treatment chamber 1. Multiple magnetic suction rods 12 are vertically arranged on the upper surface of the rotating plate 11. In this example, four magnetic suction rods 12 are provided. A lifting ring 13 is coaxially movable on the inner wall of the primary treatment chamber 1. A rotating disk 14 is coaxially rotatable on the inner side of the lifting ring 13. Multiple lifting channels 15 through which the magnetic suction rods 12 are respectively inserted are provided on the rotating disk 14. More specifically, the contact surfaces between the primary treatment chamber 1 and the lifting ring 13, the contact surfaces between the lifting ring 13 and the rotating disk 14, and the contact surfaces between the magnetic suction rods 12 and the lifting channels 15 are all airtight. A circular opening 16 is coaxially passed through the upper surface of the primary treatment chamber 1. A first water pipe 17 is provided on the outer wall of the primary treatment chamber 1, with its two ends respectively connected to the upper and lower ends of the side wall of the primary treatment chamber 1. In this example, a total of four first water pipes 17 are provided. A first valve 18 is provided on the first water pipe 17. The first valve 18 can be a sealing valve with both liquid-tight and airtight properties.

[0029] Specifically, such as Figure 3 As shown, the secondary processing chamber 2 has multiple chambers parallel to the central axis of the primary processing chamber 1 located below it and arranged in a circular array around the central axis. The lower surfaces of the secondary processing chamber 2 and the primary processing chamber 1 are connected by a second water pipe 21. The second water pipe 21 is equipped with a second valve 22. The second valve 22 can be a sealing valve that has both liquid-tight and air-tight properties. The lower end of the secondary processing chamber 2 is open.

[0030] Specifically, such as Figure 3 As shown, there are multiple intermediate rings 3 that are movably arranged parallel to the central axis and whose number matches that of the secondary processing chamber 2. They are all arranged in a circular array that matches the secondary processing chamber 2 and rotate around the central axis. The inner wall of the intermediate ring 3 matches the outer wall of the secondary processing chamber 2 in size, so that the contact surface between the inner wall of the intermediate ring 3 and the outer wall of the secondary processing chamber 2 is airtight. The inner wall of the intermediate ring 3 is coaxially provided with an installation ring 31 that carries a filter screen 32.

[0031] Specifically, such as Figure 3 As shown, there are multiple tertiary treatment chambers 4 located below the intermediate ring 3, with the same number and size as the secondary treatment chambers 2, and they are all coaxially movable within the secondary treatment chambers 2. Each tertiary treatment chamber 4 is connected to a third water pipe 41, and a third valve 42 is installed on the third water pipe 41. The third valve 42 can be a sealing valve that has both liquid-tight and air-tight properties. The upper end of each tertiary treatment chamber 4 is open.

[0032] During operation, metal cutting waste fluid is discharged from the circular opening 16 into the primary treatment chamber 1. The rotating plate 11 is rotated, causing the magnetic suction rod 12 to rotate. Simultaneously, the lifting ring 13 moves. The movement of the lifting ring 13 and the rotation of the magnetic suction rod 12 disturb the metal cutting waste fluid in the primary treatment chamber 1, ensuring full contact between the waste fluid and the magnetic suction rod 12. This allows metal impurities in the waste fluid to be adsorbed onto the magnetic suction rod 12. After adsorption is complete, the intermediate ring 3 and the tertiary treatment chamber 4 are moved upwards, causing the lower end of the secondary treatment chamber 2 to extend into the intermediate ring 3 and align with the upper surface of the mounting ring 31. The upper end of the tertiary treatment chamber 4 is inserted into the intermediate ring 3 and makes airtight contact with the upper surface of the mounting ring 31. The rotation of the rotating plate 11 is stopped, the first valve 18, the second valve 22, and the third valve 42 are opened, and the lifting ring 13 is slowly moved upward. The metal cutting waste liquid enters the first water pipe 17 from the upper end of the side wall of the primary treatment chamber 1, and then enters the space below the lifting ring 13 through the first water pipe 17. It then enters the secondary treatment chamber 2 through the second water pipe 21, and enters the tertiary treatment chamber 4 through the filter screen 32. Finally, it is discharged through the third water pipe 41.

[0033] After all the metal cutting waste fluid has passed through the filter screen 32, move the intermediate ring 3 and the tertiary treatment chamber 4 downwards. After the secondary treatment chamber 2 and the tertiary treatment chamber 4 have both left the intermediate ring 3, rotate the intermediate ring 3 so that it leaves the space between the secondary treatment chamber 2 and the tertiary treatment chamber 4. At this point, the filter screen 32 can be cleaned.

[0034] After all the metal cutting waste fluid has entered the space below the lifting ring 13, the first valve 18 can be closed and the lifting ring 13 can be moved downward. The air pressure in the space below the lifting ring 13 in the primary treatment chamber 1 will increase, which will accelerate the filtration of the filter screen 32 and improve the purification efficiency of the metal cutting waste fluid.

[0035] The equipment can also perform oil-water separation as follows: After the metal cutting waste liquid is discharged from the circular opening 16 into the primary treatment chamber 1, a demulsifier is added into the primary treatment chamber 1 from the circular opening 16 manually or through an external mechanical device. When the lifting ring 13 and the magnetic suction rod 12 disturb the metal cutting waste liquid, the demulsifier will come into full contact with the metal cutting waste liquid. After that, the disturbance of the metal cutting waste liquid by the lifting ring 13 and the magnetic suction rod 12 is stopped. The metal cutting waste liquid is allowed to stand and separate into oil and water. After separation, the oil layer on the upper layer can be discharged through the first water pipe 17, the second water pipe 21, and the third water pipe 41 by the upward movement of the lifting ring 13. Alternatively, the oil layer can be sucked out manually or by a mechanical device inserted into the outside of the circular opening 16, thus achieving oil-water separation.

[0036] Preferred, such as Figure 4As shown, a rotating groove 19 is coaxially provided on the inner side of the lifting ring 13, and a rotating ring 110 is coaxially provided on the side of the rotating disk 14. The rotating ring 110 is rotatably fitted in the rotating groove 19. A first rotating motor 111 is provided on the lower outer surface of the primary processing chamber 1. The drive shaft of the first rotating motor 111 is coaxially connected to the rotating plate 11. The first rotating motor 111 is used to drive the rotating plate 11 to rotate.

[0037] Preferred, such as Figure 5 As shown, the equipment also includes a support platform 5, on which a first support rod 51 is provided. The first support rod 51 is connected to a support frame 52, and the primary processing chamber 1 is installed on the support frame 52.

[0038] Preferred, such as Figure 4 and Figure 5 As shown, the diameters of the rotating plate 11, rotating disk 14, and circular opening 16 are matched. A mating ring 112 is coaxially provided on the bottom surface of the primary processing chamber 1. The side wall of the rotating plate 11 slides in contact with the mating ring 112, and its upper surface is coplanar with the upper surface of the mating ring 112. A right-angled groove 113 with dimensions matching the mating ring 112 is provided at the lower end of the inner side of the lifting ring 13. The lower surface of the rotating disk 14 is coplanar with the horizontal groove surface of the right-angled groove 113. The upper surface of the rotating disk 14 extends beyond the upper end of the lifting ring 13 and extends beyond... The length of the magnetic rod 12 is matched with the wall thickness of the primary processing chamber 1. The upper end of the magnetic rod 12 is coplanar with the outer upper surface of the primary processing chamber 1. The support frame 52 is provided with a linear cylinder 114 whose driving direction is perpendicular to the central axis. The drive shaft of the linear cylinder 114 is vertically connected to a push plate 115. The lower end of the push plate 115 slides in contact with the outer upper surface of the primary processing chamber 1. The outer wall of the primary processing chamber 1 is provided with a receiving chamber 116, which is located on the driving path of the linear cylinder 114.

[0039] With this design, since the size of the right-angle groove 113 matches the mating ring 112, and the lower surface of the rotating disk 14 is coplanar with the horizontal groove surface of the right-angle groove 113, when the lifting ring 13 moves down to the bottom surface of the primary processing chamber 1, the lower surface of the lifting ring 13 will contact the bottom surface of the primary processing chamber 1, the right-angle groove 113 will contact the mating ring 112, and the lower surface of the rotating disk 14 will contact the upper surface of the rotating plate 11. That is, the liquid and gas below the lifting ring 13 will all enter the first water pipe 17 and the second water pipe 21. Since the diameter of the rotating disk 14 matches the diameter of the circular opening 16, and the upper surface of the rotating disk 14 extends beyond the upper end of the lifting ring 13 with a length matching the wall thickness of the primary processing chamber 1, when the lifting ring 13 moves up to the primary processing chamber... When the lifting ring 13 moves upward, the upper surface of the lifting ring 13 will contact the upper surface of the primary processing chamber 1. The side wall of the upper surface of the rotating disk 14 extending from the lifting ring 13 will slide in contact with the inner wall of the circular opening 16. The upper surface of the rotating disk 14 will be coplanar with the upper surface of the outer side of the primary processing chamber 1. That is, all the liquid above the lifting ring 13 will enter the first water pipe 17. When the lifting ring 13 moves upward, the rotating disk 14 will scrape the metal impurities on the surface of the magnetic suction rod 12 upward. Since the upper end of the magnetic suction rod 12 is coplanar with the upper surface of the outer side of the primary processing chamber 1, when the lifting ring 13 moves upward to the upper surface of the primary processing chamber 1, the linear cylinder 114 drives the push plate 115 to move. The push plate 115 pushes the metal impurities into the receiving chamber 116.

[0040] Preferred, such as Figure 5 As shown, the support frame 52 is equipped with an assembly frame 117. A first electric lead screw 118 is mounted on the assembly frame 117 along the central axis. The drive shaft of the first electric lead screw 118 is threadedly fitted with a first mating block 119. The first mating block 119 is connected to an L-shaped rod 120. A lifting port 121 extends through the upper surface of the primary processing chamber 1. The vertical section of the L-shaped rod 120 slides through the lifting port 121 along the central axis and connects to the upper surface of the lifting ring 13. The horizontal section of the L-shaped rod 120 connects to the first mating block 119. The first electric lead screw 118 is used to drive the lifting mechanism. Ring 13 moves along the central axis; more preferably, the support frame 52 is provided with two assembly frames 117, one of which is provided with a first electric lead screw 118, and the other assembly frame 117 is provided with a first slide rod along the central axis. A slider is slidably fitted on the first slide rod, and the slider is also connected to an L-shaped rod 120. Two lifting ports 121 pass through the upper surface of the primary processing chamber 1. The vertical section of the L-shaped rod 120 connected to the slider also slides through one of the lifting ports 121 along the central axis and is connected to the upper surface of the lifting ring 13.

[0041] Preferred, such as Figure 6 As shown, the third water pipe 41 is connected to a hose 43, which is connected to the support platform 5 and is used to communicate with the water tank located below the support platform 5. The hose 43 is used to facilitate the movement of the three-stage treatment tank 4.

[0042] Preferred, such as Figure 6 As shown, the device also includes multiple dust collection chambers 6 and multiple air supply chambers 7. The number of dust collection chambers 6 matches the number of secondary processing chambers 2; that is, in this example, there are four dust collection chambers 6 and four air supply chambers 7. The dust collection chambers 6 are respectively arranged between adjacent secondary processing chambers 2 and are arranged in a circular array around the central axis together with the secondary processing chambers 2. The lower end of the dust collection chamber 6 is open and coplanar with the lower end of the secondary processing chamber 2. The outer diameter of the lower end of the dust collection chamber 6 matches the inner diameter of the intermediate ring 3. The upper end of each dust collection chamber 6 is connected to a dust collection pipe 61. The support platform 5 is equipped with a number of dust collection mechanisms 62 matching the number of dust collection chambers 6. The working end of the dust collection mechanism 62 is connected to the dust collection pipe 61. The dust collection mechanism 62 can be an industrial vacuum cleaner, used for... Dust is sucked from the top of the suction chamber 6; the number of air supply chambers 7 matches the number of the three-stage treatment chambers 4. The air supply chambers 7 are respectively arranged between adjacent three-stage treatment chambers 4 and are arranged in a circular array around the central axis together with the three-stage treatment chambers 4 and are all moved along the central axis. The top of each air supply chamber 7 is open. The outer diameter of each air supply chamber 7 matches the inner diameter of the intermediate ring 3. Each air supply chamber 7 is provided with an air supply mechanism 71 at its lower end. The air supply mechanism 71 can be a fan, which is used to supply air to the top of the air supply chamber 7. The number of intermediate rings 3 is set to twice that of the two-stage treatment chambers 2. Each of their side walls is provided with a heating mechanism 33. The heating mechanism 33 is used to heat the filter screen 32. The filter screen 32 is made of a material with good thermal conductivity.

[0043] With this design, after all the metal cutting waste liquid has passed through the filter screen 32, the first valve 18 and the third valve 42 are closed first, and the lifting ring 13 is moved upward. The air pressure in the primary treatment chamber 1, the secondary treatment chamber 2, and the tertiary treatment chamber 4 below the lifting ring 13 decreases, and the boiling point of water in the space decreases. At this time, the heating mechanism 33 heats the filter screen 32, and the water in the impurities on the filter screen 32 evaporates. After evaporation is complete, the first valve 18 is opened to balance the air pressure, and the intermediate ring 3 and the tertiary treatment chamber 4 are moved downward. After the secondary treatment chamber 2 and the tertiary treatment chamber 4 have both left the intermediate ring 3, the intermediate ring 3 is rotated to move the intermediate ring 3 away from the secondary treatment chamber. Between chamber 2 and the tertiary treatment chamber 4, and with the intermediate ring 3 positioned between the dust collection chamber 6 and the air supply chamber 7, the air supply chamber 7 and the intermediate ring 3 are moved upwards, so that the lower end of the dust collection chamber 6 extends into the intermediate ring 3 and makes airtight contact with the upper surface of the mounting ring 31, and the upper end of the air supply chamber 7 extends into the intermediate ring 3 and makes airtight contact with the upper surface of the mounting ring 31. At this time, the air supply mechanism 71 blows the dried impurities on the filter screen 32, and the dust collection mechanism 62 sucks away the dried impurities. At the same time, since the number of intermediate rings 3 is set to twice that of the secondary treatment chamber 2, the next filtration and purification operation can be carried out simultaneously while cleaning the dried impurities on the filter screen 32.

[0044] Preferred, such as Figure 7As shown, two hanging rods 23 are connected to the lower outer surface of the primary processing chamber 1. The lower end of the hanging rods 23 is connected to the same hanging plate 24. The hanging plate 24 is connected to eight mounting rods 25, matching the number of the secondary processing chamber 2 and the dust collection chamber 6. Each mounting rod 25 is connected to a mounting frame 26. The secondary processing chamber 2 and the dust collection chamber 6 are respectively mounted on the mounting frame 26. This design is used to fix the secondary processing chamber 2 and the dust collection chamber 6.

[0045] Preferred, such as Figures 7-9 As shown, a second rotating motor 34 coaxially with the primary processing chamber 1 is provided on the hanging plate 24. The drive shaft of the second rotating motor 34 is coaxially connected to a drive disk 35. The drive disk 35 is connected to a number of drive rods 36 matching the number of the intermediate ring 3. Each drive rod 36 is connected to a drive frame 37. Each drive frame 37 is provided with a pair of vertical rods 38 along the central axis. Each vertical rod 38 is coaxially fitted with a spring 39. Each intermediate ring 3 is connected to a pair of connecting blocks 310. The pair of connecting blocks 310 are slidably fitted onto the pair of vertical rods 38. The two ends of the spring 39 are connected to the drive frame 37 and the connecting blocks 310 respectively. When the spring 39 is in its original state, the intermediate ring 3 is located below the secondary processing chamber 2.

[0046] With this design, the second rotating motor 34 is used to drive the intermediate ring 3 to rotate. And because of the spring 39, the intermediate ring 3 no longer needs to be equipped with a separate linear drive mechanism. Instead, it first contacts the third-level processing chamber 4 when the third-level processing chamber 4 moves upward, and then contacts the second-level processing chamber 2 under the drive of the third-level processing chamber 4.

[0047] Preferred, such as Figure 10 As shown, the support platform 5 is provided with four second support rods 44. The upper ends of the second support rods 44 are connected to the same support plate 45. The upper surface of the support plate 45 is provided with a second electric lead screw 46 along the central axis. The second electric lead screw 46 is threadedly engaged with a second mating block 47. More preferably, the upper surface of the support plate 45 is also provided with a second sliding rod along the central axis. The second mating block 47 slides through the second sliding rod. The second mating block 47 is connected to eight connecting rods 48, matching the number of the three-stage treatment chamber 4 and the air supply chamber 7. Each connecting rod 48 is connected to a connecting frame 49. The three-stage treatment chamber 4 and the air supply chamber 7 are respectively connected to the connecting frame 49. The second electric lead screw 46 is used to drive the three-stage treatment chamber 4 and the air supply chamber 7 to move.

[0048] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
