[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1, referring to Figure 1-3 A metal processing coolant wastewater regeneration system includes a treatment tank 1. The upper part of the treatment tank 1 is provided with a top cover, and the top cover is provided with a feed inlet 2. The bottom of the treatment tank 1 is also provided with a liquid outlet. A guide rod 9 is vertically installed at the bottom of the treatment tank 1. An oil collection hopper 4 is connected to the upper part of the inner side of the treatment tank 1 through a drive component. A pipe body 8 is provided at the bottom of the oil collection hopper 4, and the top of the guide rod 9 extends to the inner side of the pipe body 8. The oil collection hopper 4 and the pipe body 8 are connected through a feed hole 15. Exchange holes 7 are evenly opened on the outer side of the pipe body 8. A hydrophilic and oleophobic film 24 is provided in the exchange holes 7. Several kapok fiber balls 22 are also placed at the bottom of the pipe body 8.

[0030] The driving components include an electric telescopic rod 3, a connecting frame 5, and a bracket 6. The electric telescopic rod 3 is fixed to the upper inner side of the treatment box 1, the connecting frame 5 is fixed to the bottom of the electric telescopic rod 3, and the bracket 6 is arranged in a ring array between the connecting frame 5 and the oil collection hopper 4. The top of the guide rod 9 is arranged in a ring array with multiple sets of control structures. The multiple sets of control structures are used to clean the hydrophilic and oleophobic film 24 and control the water and oil separation in the pipe body 8.

[0031] Reference Figure 5-7 The control structure includes a baffle 16, a straight rod 17, and an oil-wiping cloth 19. The straight rod 17 is arranged in a ring array on the upper circumferential position of the guide rod 9. The baffle 16 is vertically installed at the far end of the straight rod 17 and is attached to the inner wall of the tube body 8. The oil-wiping cloth 19 is adhered to the lower end of one side of the baffle 16. During the up-and-down movement of the baffle 16 and the oil-wiping cloth 19, it will come into contact with the hydrophilic and oleophobic film 24. The hydrophilic and oleophobic film 24 is specifically a polytetrafluoroethylene modified film, and the thickness of the hydrophilic and oleophobic film 24 matches the thickness of the exchange hole 7.

[0032] A slot 20 is provided at the lower end of one side of the baffle 16. Multiple elastic blocks 18 are arranged from top to bottom in the slot 20. The other side of the elastic block 18 is bonded to the oil wiping cloth 19.

[0033] Wastewater containing coolant is injected into the treatment tank 1 through the inlet 2. The liquid level is controlled so that it is below the oil collection hopper 4 at the initial position. The electric telescopic rod 3 is activated to move downwards, and the position of the oil collection hopper 4 drops. When the upper edge of the oil collection hopper 4 just covers the upper liquid surface of the wastewater, the oil floating on the water surface enters the inner side of the oil collection hopper 4 and enters the interior of the pipe body 8 through the inlet 15. When the electric telescopic rod 3 returns and drives the oil collection hopper 4 to rise, the floating oil on the liquid surface stops entering the oil collection hopper 4. At the same time, the hydrophilic and oleophobic film 24 is a polytetrafluoroethylene modified film. After the oil collection hopper 4 leaves the wastewater, the water that has entered the pipe body 8 is discharged again by utilizing the hydrophilic properties of the polytetrafluoroethylene modified film, leaving the oil inside the pipe body 8.

[0034] As the oil collecting hopper 4 descends, the positions of the top baffle 16 and the straight rod 17 of the guide rod 9 remain unchanged. When the baffle 16 coincides with the position of the hydrophilic-oleophobic membrane 24, the baffle 16 and the oil-wiping cloth 19 installed at its lower end can wipe the surface of the hydrophilic-oleophobic membrane 24 during the continued descent of the pipe body 8, removing particulate impurities adhering to the surface of the hydrophilic-oleophobic membrane 24, ensuring the normal working efficiency of the hydrophilic-oleophobic membrane 24. At the same time, the oil-wiping cloth 19 and the baffle 16 are used to seal the exchange hole 7 to prevent wastewater from entering the pipe body 8. During the process below the surface, a large amount of water enters the pipe body 8 through the exchange hole 7. Secondly, multiple elastic blocks 18 are provided inside the groove 20 at the lower end of the baffle 16. When the oil wiping cloth 19 comes into contact with the exchange hole 7, the elastic blocks 18 tightly press the oil wiping cloth 19 against one side of the hydrophilic and oleophobic film 24. The oil wiping cloth 19 is made of a waterproof material. When the oil collecting hopper 4 moves upward, the baffle 16 and the exchange hole 7 separate from each other, thus exposing the exchange hole 7. This facilitates the drainage of water inside the pipe body 8 after the oil collecting hopper 4 is suspended in the air.

[0035] Example 2, Reference Figure 5-6 The difference between this embodiment and embodiment 1 is that the guide rod 9 inside the tube body 8 has multiple sets of toggle components arranged in a ring array outside. The toggle components include a main board 21, a toggle 23 and a notch 14.

[0036] The main board 21 is vertically fixed to the outside of the guide rod 9. The paddles 23 are symmetrically arranged on both sides of the main board 21, and the two paddles 23 are inclined upward. The notch 14 is opened through the paddle 23.

[0037] To better absorb the oil entering the tube body 8, kapok fiber balls 22 are added to the bottom of the tube body 8. This material is mainly used to absorb oil. Using the kapok fiber balls 22 to absorb oil increases the amount of oil absorbed. Meanwhile, multiple sets of main plates 21 and symmetrically arranged paddles 23 on both sides of the main plates 21 are evenly arranged at the upper outer side of the guide rod 9. When the tube body 8 descends, the paddles 23 squeeze and agitate the kapok fiber balls 22 at the lower end of the tube body 8. The kapok fiber balls 22 then enter the space between the main plates 21 and the paddles 23. The oil will fall through the notch 14 on the paddle 23. During the stirring process, it can effectively break the water-oil surface layer inside the tube 8, allowing the re-entering oil molecules to contact the kapok fiber balls 22 more quickly. Secondly, as mentioned above, the wastewater contains some particulate matter. These particulate matter adheres to the outer surface of the kapok fiber balls 22, causing the fiber pores inside the kapok fiber balls 22 to be blocked. Later, when cleaning the inside of the tube 8, most of the oil is concentrated on the kapok fiber balls 22, making cleaning easier.

[0038] Example 3, Reference Figure 4The difference between this embodiment and Embodiments 1 and 2 is that an aeration assembly 13 is provided at the bottom of the treatment tank 1. Several sets of aeration assemblies 13 are arranged in an array at the bottom of the treatment tank 1. A strong oxidant, ozone, is injected into the treatment tank 1 through multiple sets of aeration assemblies 13. Multiple sets of first ropes 11 are suspended from the lower end of the oil collecting hopper 4. A magnetic ring 10 is fixedly attached to the bottom of the first rope 11. A second rope 12 is connected between the magnetic ring 10 and the bottom of the treatment tank 1. The redundancy of the second rope 12 is greater than that of the first rope 11. Multiple magnetic rings 10 swing with the rising air bubbles, and adjacent magnetic rings 10 are not affected by magnetic adsorption.

[0039] The wastewater containing coolant may contain metal fragments and microorganisms. These substances need to be treated before the coolant can be recycled to the next stage.

[0040] To this end, an array of aeration components 13 is arranged at the bottom of the treatment tank 1 to add ozone to the coolant inside the treatment tank 1. Ozone can effectively remove microorganisms and prevent the growth of microorganisms in the coolant. Secondly, a magnetic ring 10 is fixed between the oil collection hopper 4 and the treatment tank 1 by a first rope 11 and a second rope 12. The magnetic ring 10 uses its adsorption capacity to adsorb metal particles. At the same time, the redundancy of the second rope 12 is greater than that of the first rope 11, so that the magnetic ring 10 can move up and down with the oil collection hopper 4. Due to the ozone injected by the aeration components 13 below, upward bubbles are continuously generated in the coolant wastewater. The movement and breakage of the bubbles can cause the first rope 11 to swing. When the first rope 11 swings, the magnetic ring 10 can swing within a certain range inside the treatment tank 1, increasing the range of motion of the magnetic ring 10. When swinging, the adsorption effect of the magnetic ring 10 on metal particles can be improved. In addition, a certain distance is set between adjacent magnetic rings 10 so that they will not be attracted to each other during operation.

[0041] The working principle of this device is as follows:

[0042] Wastewater containing coolant is injected into the treatment tank 1 through the inlet 2. The liquid level is controlled so that it is below the oil collection hopper 4 at the initial position. The electric telescopic rod 3 is activated to move downwards, and the position of the oil collection hopper 4 drops. When the upper edge of the oil collection hopper 4 just covers the upper liquid surface of the wastewater, the oil floating on the water surface enters the inner side of the oil collection hopper 4 and enters the interior of the pipe body 8 through the inlet 15. When the electric telescopic rod 3 returns and drives the oil collection hopper 4 to rise, the floating oil on the liquid surface stops entering the oil collection hopper 4. At the same time, the hydrophilic and oleophobic film 24 is a polytetrafluoroethylene modified film. After the oil collection hopper 4 leaves the wastewater, the water that has entered the pipe body 8 is discharged again by utilizing the hydrophilic properties of the polytetrafluoroethylene modified film, leaving the oil inside the pipe body 8.

[0043] As the oil collecting hopper 4 descends, the positions of the top baffle 16 and the straight rod 17 of the guide rod 9 remain unchanged. When the baffle 16 coincides with the position of the hydrophilic-oleophobic membrane 24, the baffle 16 and the oil-wiping cloth 19 installed at its lower end can wipe the surface of the hydrophilic-oleophobic membrane 24 during the continued descent of the pipe body 8, removing particulate impurities adhering to the surface of the hydrophilic-oleophobic membrane 24, ensuring the normal working efficiency of the hydrophilic-oleophobic membrane 24. At the same time, the oil-wiping cloth 19 and the baffle 16 are used to seal the exchange hole 7 to prevent wastewater from entering the pipe body 8. During the process below the surface, a large amount of water enters the pipe body 8 through the exchange hole 7. Secondly, multiple elastic blocks 18 are provided inside the groove 20 at the lower end of the baffle 16. When the oil wiping cloth 19 comes into contact with the exchange hole 7, the elastic blocks 18 tightly press the oil wiping cloth 19 against one side of the hydrophilic and oleophobic film 24. The oil wiping cloth 19 is made of a waterproof material. When the oil collecting hopper 4 moves upward, the baffle 16 and the exchange hole 7 separate from each other, thus exposing the exchange hole 7. This facilitates the drainage of water inside the pipe body 8 after the oil collecting hopper 4 is suspended in the air.

[0044] To better absorb the oil entering the tube body 8, kapok fiber balls 22 are added to the bottom of the tube body 8. This material is mainly used to absorb oil. Using kapok fiber balls 22 to absorb oil can increase the amount of oil absorbed. At the same time, multiple sets of main plates 21 and symmetrically arranged paddles 23 on both sides of the main plates 21 are evenly arranged on the upper outer side of the guide rod 9. When the tube body 8 is lowered, the paddles 23 will squeeze and stir the kapok fiber balls 22 at the lower end of the tube body 8. During the stirring process, the water-oil surface layer inside the tube body 8 can be effectively broken, so that the oil molecules that re-enter can contact the kapok fiber balls 22 more quickly. Secondly, as mentioned above, the wastewater contains some particulate matter. These particulate matter adheres to the outer surface of the kapok fiber balls 22, which will cause the fiber pores inside the kapok fiber balls 22 to be blocked. When cleaning the inside of the tube body 8 later, most of the oil is concentrated on the kapok fiber balls 22, making cleaning easier.

[0045] The wastewater containing coolant may contain metal fragments and microorganisms. These substances need to be treated before the coolant can be recycled to the next stage.

[0046] To this end, an array of aeration components 13 is arranged at the bottom of the treatment tank 1 to add ozone to the coolant inside the treatment tank 1. Ozone can effectively remove microorganisms and prevent the growth of microorganisms in the coolant. Secondly, a magnetic ring 10 is fixed between the oil collection hopper 4 and the treatment tank 1 by a first rope 11 and a second rope 12. The magnetic ring 10 uses its adsorption capacity to adsorb metal particles. At the same time, the redundancy of the second rope 12 is greater than that of the first rope 11, so that the magnetic ring 10 can move up and down with the oil collection hopper 4. Due to the ozone injected by the aeration components 13 below, upward bubbles are continuously generated in the coolant wastewater. The movement and breakage of the bubbles can cause the first rope 11 to swing. When the first rope 11 swings, the magnetic ring 10 can swing within a certain range inside the treatment tank 1, increasing the range of motion of the magnetic ring 10. When swinging, the adsorption effect of the magnetic ring 10 on metal particles can be improved. In addition, a certain distance is set between adjacent magnetic rings 10 so that they will not be attracted to each other during operation.

[0047] This approach simultaneously addresses the issues of oil, microorganisms, and metal particles in the coolant wastewater.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
