[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1-8As shown:

[0036] A mobile cutting fluid purification device includes a water inlet pipe 1 for introducing cutting fluid into a pipe filter 2. The end of the pipe filter 2 is designed to be open. A collection bucket 3 is fixed to the outside of the pipe filter 2 for collecting cutting fluid that passes through the pipe filter 2 and / or is filtered by the pipe filter 2. The cutting fluid in the collection bucket 3 is filtered through a paper tape filter 4 and then enters a treatment box 5. The cutting fluid inside the treatment box 5 is purified by dissolved air flotation technology.

[0037] In this solution, the pipe filter 2 is an improved design made of a water pipe. The core structure is a pipe wall made of a filter mesh. The pipe wall of the pipe filter 2 can be a filtration aperture of 100 mesh. When the cutting fluid passes through the pipe filter 2, the pipe filter 2 not only has the function of a pipe and can transport the cutting fluid, but also can filter some larger iron chips in the cutting fluid during the transportation process, thereby improving the purification efficiency of the cutting fluid and reducing the workload of subsequent purification. The pipe filter 2 does not force the filtration of all the cutting fluid, but only performs adaptive filtration work when the cutting fluid flows through the pipe filter 2. When the flow rate of the cutting fluid increases or the pipe filter 2 is blocked, the excess cutting fluid is directly discharged from the end of the pipe filter 2, and part of the cutting fluid is filtered and flows out from the filter wall of the pipe filter 2, thereby achieving adaptive filtration work. The filtered cutting fluid, or the cutting fluid discharged directly through the end of the pipe filter 2 will enter the collection barrel 3, and then the cutting fluid in the collection barrel 3 is transported to the paper tape filter 4 for secondary filtration. The pipe filter 2 can filter 20%-30% of the iron in the cutting fluid. Cutting, the paper filter 4 can filter 40% -50% of the iron cuttings in the cutting fluid, the cutting fluid filtered by the paper filter 4 enters the processing box 5, and then the cutting fluid inside the processing box 5 is purified by dissolved air flotation technology. Dissolved air flotation technology is a commonly used technical means in the field of cutting fluid purification. It uses hydraulic cutting and high and low pressure instantaneous conversion to make the multi-phase combination of water, emulsified oil (combined oil), and solid particles in the cutting fluid undergo phase change, and by destroying the emulsified or agglomerated state of the emulsified oil, liquid, and particles, the oil droplets (including The solid particles are also separated due to the crushing of agglomeration, and the relatively heavy iron chips sink due to their own weight. For other impurities with lighter mass (including dissolved oil, combined oil, and light particles), the negative pressure principle (such as the vacuum effect generated by high-speed fluid) is used to actively adsorb the floating oil on the surface of the cutting fluid, or to make tiny oil droplets float up under the influence of cavitation bubbles, so as to achieve efficient collection of floating oil. Finally, the scraping mechanism in the dissolved air flotation technology is used to scrape off the floating foam to achieve purification of the cutting fluid.

[0038] In an optional embodiment, the processing box 5 includes a processing area A 26, a processing area B 27 and a processing area C 28. The cutting fluid inside the processing area A 26 is purified by dissolved air flotation technology, the slag in the processing area A 26 enters the processing area B 27 for temporary storage, and the cutting fluid purified in the processing area A 26 is transported to the processing area C 28, and ozone is introduced into the processing area C 28.

[0039] In this embodiment, after the cutting fluid in the treatment area A 26 is purified by the dissolved air flotation technology, the purified cutting fluid in the treatment area A 26 is transported to the treatment area C 28 by a water pump. A submersible pump or a centrifugal pump and a water pipe can be used. When extracting the cutting fluid in the treatment area A 26, the liquid portion in the middle layer of the area can be extracted; the purified cutting fluid entering the treatment area C 28 is sterilized by ozone to restore the cutting fluid. When the ozone is introduced, a plurality of air bubbles can be evenly installed at the bottom of the treatment area C 28, and the plurality of air bubbles are connected to the ozone gas delivery hose.

[0040] The ozone sterilization step and the dissolved air flotation technology for purifying cutting fluid are treated in different areas. In order to prevent the two treatment methods from affecting each other, ozone has strong oxidizing properties, which can oxidize the surfactants on the surface of the flotation microbubbles (such as emulsifiers and soaps in the cutting fluid), reducing the adsorption capacity of the bubbles and pollutants. If the ozone dosage is too high, it may cause the microbubbles to rupture faster, shorten their residence time in the water, and weaken the flotation effect.

[0041] In an optional embodiment, the axis of the pipe filter 2 is perpendicular to the ground.

[0042] In this embodiment, the pipe filter 2 is arranged vertically. With the help of gravity, the cutting fluid introduced will naturally sink to the bottom, so that the initial area of the filter in contact with the cutting fluid can fully carry out the filtering operation first. When the area is blocked due to the continuous accumulation of impurities, the liquid level will gradually rise during the continuous introduction of cutting fluid, allowing other areas of the pipe filter 2 to start filtering. This arrangement can ensure the filtering effect while preventing the cutting fluid from being directly discharged from the end of the pipe filter 2 without being fully filtered when the filter still has filtering capacity. In addition, the vertically arranged pipe filter 2 allows large particles of iron chips to naturally settle during the filtering process of the cutting fluid, reducing the filtering burden and making it easier to clean the iron chips in a centralized manner.

[0043] In an optional embodiment, the filter tube wall of the pipeline filter 2 is a conical structure that is larger at the top and smaller at the bottom.

[0044] In this embodiment, the pipe filter 2 has a conical structure design with a larger upper portion and a smaller lower portion. The iron cuttings are deposited in the area near the top of the cone, which makes the discharge of the iron cuttings smoother and less likely to cause dead corners.

[0045] In an optional embodiment, the bottom of the pipe filter 2 is sleeved on the outer surface of the water inlet pipe 1 through an elastic ring 61 .

[0046] In this embodiment, in order to ensure the sealing of the pipe filter 2 and to ensure that the iron cuttings that sink to the bottom of the pipe filter 2 can be discharged, the bottom of the pipe filter 2 is pressed against the outer surface of the water inlet pipe 1 with a certain pressure by the elastic ring 61, thereby achieving a temporary closure between the pipe filter 2 and the outer surface of the water inlet pipe 1 (such as Figure 6 As shown in the figure, the angle between the pipe filter 2 and the water inlet pipe 1 is used to temporarily store the sunken iron cuttings. Excessive accumulation of iron cuttings will occupy the filtering area of the pipe filter 2. When new cutting fluid to be filtered is continuously introduced, the effective filtering area of the pipe filter 2 is reduced, which will cause the internal pressure of the pipe filter 2 to increase. The pressure will open the elastic ring 61 at the bottom of the pipe filter 2, thereby discharging the iron cuttings at the bottom. After the iron cuttings are discharged, there is no accumulation of iron cuttings to occupy the filtering area of the pipe filter 2, and the effective filtering area of the pipe filter 2 is restored. When new cutting fluid to be filtered is continuously introduced, the internal pressure will not increase.

[0047] In an optional embodiment, the drainage end of the water inlet pipe 1 is fixedly connected to an inner pipe 6 for extending to the upper layer of the pipe filter 2 .

[0048] In this embodiment, the inner tube 6 and the water inlet pipe 1 should be made of hard materials, such as Figure 4 As shown, the inner tube 6 extends to the middle and upper layers of the pipe filter 2. When iron cuttings are deposited, the discharge port of the inner tube 6 is far away from the deposited part of the iron cuttings. When the cutting fluid is introduced through the inner tube 6, the turbulence has little interference on the sinking iron cuttings, thereby preventing or reducing the turbulence caused by the turbulence of the liquid, which causes the iron cuttings to be unable to sink.

[0049] At the same time, due to the increase in the length of the inner tube 6 entering the pipeline filter 2, the amount of iron cuttings that can be effectively deposited between the inner tube 6, the angle between the water inlet pipe 1 and the pipeline filter 2 can be increased, which can be more conducive to controlling the discharge of iron cuttings, and when discharging iron cuttings, the discharge of cutting fluid can be relatively reduced. If the deposited iron cuttings are less, more iron cuttings will be in a turbulent flow carrying state for a long time due to turbulence, so there is a greater probability that the iron cuttings will adhere to the inner wall of the pipeline filter 2 and affect filtration. When the filtration speed of the cutting fluid is less than the introduction speed of the cutting fluid, the liquid level inside the pipeline filter 2 will continue to increase, which will cause the internal pressure of the pipeline filter 2 to gradually increase. When the pressure is large enough, it will break through the restriction of the elastic ring 61, and the bottom of the pipeline filter 2 will open, resulting in the discharge of a small amount of iron cuttings and relatively more cutting fluid.

[0050] In an optional embodiment, a fixing ring 10 is fixedly connected to the top of the pipe filter 2, the outer end surface of the fixing ring 10 is fixedly connected to the inner wall surface of the collecting barrel 3, and a through hole 11 is opened at the fixing ring 10 between the collecting barrel 3 and the pipe filter 2.

[0051] In this embodiment, the pipe filter 2 is a flexible filter mesh, which itself does not have a good structural support effect. In order to maintain the top position, the top of the pipe filter 2 is fixed by a fixing ring 10 fixed to the collection bucket 3, which plays a fixed support effect. At the same time, the through hole 11 opened on the fixing ring 10 can allow the cutting fluid to pass through the through hole 11 into the collection bucket 3 when it overflows from the top of the pipe filter 2.

[0052] In an optional embodiment, a top cover 7 is provided at the top of the fixing ring 10 , and a counterweight 8 is fixed at the center of the top surface of the top cover 7 . The diameter of the top cover 7 is smaller than the diameter of the collecting barrel 3 and larger than the diameter of the fixing ring 10 .

[0053] In this embodiment, a sealing ring can be fixedly attached at the position where the top cover 7 contacts the fixing ring 10, and the upper shell 17 is detachably fixedly mounted on the top of the front shell 16 to cover the upper portion of the collecting barrel 3. The counterweight 8 on the top cover 7 gives the top cover 7 a certain weight. When the cutting fluid level in the pipeline filter 2 rises to the top cover 7, continued injection of cutting fluid will cause the liquid pressure inside the pipeline filter 2 to suddenly increase. The increased internal pressure of the pipeline filter 2 will force its bottom to overcome the elasticity of the elastic ring 61 and open, thereby discharging the iron shavings deposited at the bottom of the pipeline filter 2.

[0054] When the bottom of the pipe filter 2 is not discharged in time and the cutting fluid continues to flow in, the liquid pressure will push the top cover 7 open and separate it from the fixing ring 10, thereby causing the cutting fluid to overflow and avoid the pipe filter 2 from bursting. In order to increase the tensile strength of the pipe filter 2, a reinforcing rib 12 is fixedly installed on the outside of the pipe filter 2.

[0055] In an optional embodiment, a plurality of isolating balls 9 distributed at equal intervals are fixedly connected to the outer end surface of the top cover 7 .

[0056] In this embodiment, the isolation ball 9 can keep the top cover 7 as concentric as possible when covering the fixing ring 10, and the contact resistance between the isolation ball 9 and the inner wall of the collection bucket 3 is small, which is conducive to automatic self-correction under the influence of gravity.

[0057] In an optional embodiment, a fitting portion 13 fixed to the outer surface of the pipe filter 2 is provided at the bottom of the collecting barrel 3, and the gap between the minimum diameter of the fitting portion 13 and the outer diameter of the inner tube 6 is greater than the thickness of the pipe filter 2. A sealing layer is located between the covering area of the fitting portion 13 and the bottom end of the pipe filter 2.

[0058] In this embodiment, since the pipe filter 2 is a flexible filter tube, the fitting portion 13 is required to maintain its bottom position. The fitting portion 13 and the pipe filter 2 are in surface contact, which prevents the cutting fluid from leaking downward from the connection between the two. When the internal pressure of the pipe filter 2 increases, the bottom of the pipe filter 2 can be better maintained open. If there is no fitting portion 13, the bottom of the pipe filter 2 will be severely pulled down when it is under pressure, making the pipe filter 2 easily damaged and not conducive to the opening of the bottom of the pipe filter 2.

[0059] The sealing layer is located between the covering area of the fitting portion 13 and the bottom end of the pipe filter 2, which can prevent the cutting fluid from directly penetrating downward from this part. The pipe filter 2 is a flexible filter material and can be processed by coating the sealing layer part to make this part a sealing layer.

[0060] Further,

[0061] The rear shell 15 and the front shell 16 are both fixedly mounted on the base 14. The bottom of the base 14 is equipped with universal wheels for movement. The processing box 5 is installed in the rear shell 15. There is a certain space between the bottom of the processing box 5 and the bottom of the rear shell 15 for pipeline installation. The bottoms of the three processing areas of the processing box 5 are respectively connected to three pipes B29. The ends of the water inlet pipe 1 and the three pipes B29 are all equipped with manual valves 30 for controlling the passage and disconnection of the water inlet pipe 1 or the pipe B29. The pipeline in the cutting fluid delivery equipment is connected to the manual valve 30 installed at the end of the water inlet pipe 1. The cutting fluid delivery device is a device that can deliver the used cutting fluid at a certain pressure. That is, the cutting fluid in the water inlet pipe 1 can enter the inner side of the pipe filter 2. The liquid pressure is provided by the cutting fluid delivery device. After being filtered or delivered by the cutting fluid delivery device, the cutting fluid enters the inner side of the collecting barrel 3. It will first enter the pipe A19 and then be pressurized and delivered to the paper tape filter 4 by the liquid pump 20. One end of the hose can be connected to the water inlet 22 of the paper tape filter 4. The hose is then connected to the output end of the liquid pump 20 after passing through the mounting hole 21.

[0062] The iron shavings discharged from the bottom end of the pipe filter 2 will fall into the collection shell 23. The door panel 24 provided on the front shell 16 can be opened to remove the collection shell 23, so that the collection shell 23 can be easily dumped and cleaned.

[0063] The dissolved air flotation equipment can be connected to the control panel 18 for centralized operation. The dissolved air flotation equipment can be controlled through the control panel 18, for example, the purification time of the dissolved air flotation equipment and the liquid level display in the dissolved air flotation equipment can be controlled. It should be noted that the current dissolved air flotation equipment is generally equipped with a mechanism for detecting the liquid level. The liquid level detection is coordinated with the scraping mechanism. When the liquid level reaches the target value, the scraper in the scraping mechanism can contact the foam, and then the foam can be effectively scraped to other areas for temporary storage. The liquid pump 20 can also be connected to the control panel 18 to control the flow rate of the liquid pump 20. The paper tape filter 4 can also be connected to the control panel 18 to control the working power of the paper tape filter 4. The installation pipe 25 is provided to facilitate the ozone delivery pipe to be placed in the C treatment area 28 together with the bubble stone.
