Description

Technical Field

[0001] This utility model relates to the technical field of cutting fluid recovery equipment, specifically to an integrated device for circulating, purifying, and regenerating machining cutting fluid. Background Technology

[0002] In machining, cutting fluid plays a crucial role. It effectively cools the cutting tool and workpiece, reducing damage from the high temperatures generated during cutting and extending tool life. It also provides excellent lubrication, reducing friction between the tool and workpiece, improving surface finish, reducing surface roughness, and ensuring machining accuracy. Furthermore, cutting fluid promptly removes chips generated during machining, preventing them from scratching the machined surface and maintaining a clean machining environment.

[0003] However, used cutting fluids often contain a large amount of impurities, such as metal shavings, grinding wheel powder, and other solid particles, as well as oil contamination from equipment lubrication system leaks, and may also breed a large number of bacteria. Directly discharging this used cutting fluid will cause serious pollution to the soil, water bodies, and other ecological environments, harming the living environment of plants and animals and disrupting the ecological balance. Furthermore, the frequent purchase and use of cutting fluid can lead to high costs for enterprises. According to relevant statistics, in some machining companies, the purchase cost of cutting fluid accounts for 5%-10% of the company's production cost; if the cost of disposing of waste cutting fluid is added, the cost percentage will be even higher. Therefore, effective recycling, purification, and regeneration of cutting fluids is of significant practical importance.

[0004] Currently, various cutting fluid circulation, purification, and regeneration devices exist on the market. For example, patent application number CN202022360199 discloses a cutting fluid purification and regeneration circulation system, which includes a filtration device, an oil separation device, and a sterilization device. An aeration device is installed at the bottom of the oil separation chamber, connected to an external ozone sterilizer. The aeration device decomposes air into ultra-small bubbles, rapidly separating oil molecules suspended in the water from the bottom to the liquid surface. This increases the oil separation rate while the ozone sterilizer effectively kills anaerobic bacteria and other organic matter proliferating in the cutting fluid, preventing it from developing an odor. However, in practical applications, this device is not very effective at filtering highly viscous impurities, and its overall structure is relatively complex, resulting in high maintenance costs. Another example is patent application number CN202123442387, which proposes a cutting fluid regeneration and reuse device. This device uses a fiber braided tube as the main separation process, combined with a centrifuge for solid-liquid separation. This device offers moderate filtration precision and high water production, effectively removing floating oil and reducing the investment and operating costs of cutting fluid reuse. However, it is not thorough enough in filtering fine particulate impurities in the cutting fluid, making it difficult for the regenerated cutting fluid to meet the requirements of some high-precision machining applications. For example, patent application CN202310637048 describes a cutting fluid circulation and purification device for machine tools. By setting up a solid-liquid separation mechanism, it achieves coordinated solid-liquid separation, waste chip ejection, waste chip expulsion and compression, and waste chip recycling operations, improving solid-liquid separation efficiency. However, this device is not ideal for processing cutting fluids containing various complex impurities, and cannot effectively remove oil and bacteria from the cutting fluid. Utility Model Content

[0005] The purpose of this invention is to provide an integrated device for circulating, purifying, and regenerating machining cutting fluid, addressing the issues raised in the background art where used machining cutting fluid often contains a large amount of impurities, such as metal shavings, grinding wheel powder, and other solid particles, as well as oil contamination from equipment lubrication system leaks, and may also breed a large number of bacteria. Directly discharging this used cutting fluid would cause serious pollution to the soil, water bodies, and other ecological environments, harming the living environment of plants and animals and disrupting the ecological balance.

[0006] To achieve the above objectives, this utility model provides an integrated device for circulating, purifying, and regenerating machining cutting fluid, including a cutting fluid collection tank. A filter assembly is connected to one side of the cutting fluid collection tank, and an oil-gas separation component is connected to one end of the filter assembly. The oil-gas separation component includes a dissolved gas tank and a separation pool. A regenerated liquid storage tank is connected to one side of the oil-gas separation component, and a disinfection component is installed on the top inner wall of the regenerated liquid storage tank.

[0007] This setup collects waste cutting fluid generated during machining through a cutting fluid collection tank. After solid impurities are removed by a filtration component, the fluid enters an oil-gas separation unit (dissolved gas tank and separation pool) to separate oil contaminants. The resulting purified regenerated fluid is stored in a regenerated fluid storage tank. A sterilization unit then sterilizes the regenerated fluid, enabling recycling.

[0008] Preferably, the filtration assembly includes a coarse filter chamber, a fine filter chamber, and a magnetic filter connected in series. The coarse filter chamber is equipped with a coarse filter screen to intercept large particulate impurities in the waste cutting fluid. The fine filter chamber is equipped with a fine filter screen to filter out fine particulate impurities in the waste cutting fluid. The magnetic filter is used to adsorb ferromagnetic impurities in the waste cutting fluid.

[0009] This setup filters out particles from large to small, including magnetic impurities, layer by layer, improving filtration efficiency and precision, and ensuring that the liquid entering subsequent processing stages has a low impurity content.

[0010] Preferably, the dissolved gas tank is externally connected to an air inlet pipe, the drain end of the filter assembly is connected to the dissolved gas tank via a pipeline, one side of the dissolved gas tank is connected to the separation tank via a discharge pipe, and a feed pump is installed on the discharge pipe.

[0011] The filtered liquid enters the dissolved gas tank through a pipeline, and air (or other gas) is introduced into the tank through the air inlet pipe to form dissolved gas water. The dissolved gas water is pressurized by the feed pump and then transported to the separation tank through the discharge pipe. The tiny bubbles generated when the dissolved gas is released adsorb oil droplets and suspended matter in the liquid, causing them to float to the surface and be separated.

[0012] Preferably, a stirring rod is vertically arranged inside the dissolved gas tank, and several stirring blades are installed on the outer wall of the stirring rod. The top of the stirring rod is driven to rotate by a stirring motor.

[0013] This feature involves a stirring rod inside the dissolved gas tank that is driven by a stirring motor to rotate, which in turn drives the stirring blades to agitate the liquid, ensuring that the introduced gas and liquid are fully mixed and accelerating the dissolution of the gas to form a uniform dissolved gas water.

[0014] Preferably, the separation tank is equipped with a vertical partition with an overflow port. The partition divides the separation tank into a regenerated liquid tank and an oil tank. A distributor is installed on the upper part of the regenerated liquid tank. The inlet of the distributor is connected to the discharge pipe. The bottom of the distributor has several downward-facing distribution holes.

[0015] This feature separates the tank into a regenerated liquid tank and an oil tank using a partition. The distributor evenly disperses the dissolved air water into fine streams, allowing the air bubbles to fully contact the oil droplets, while the floating oil sludge gathers in the oil tank. The overflow port allows the purified liquid to overflow from the regenerated liquid tank to the other side of the oil tank, achieving liquid-sludge separation.

[0016] Preferably, the bottom side of the regenerated liquid tank is connected to the regenerated liquid storage tank via a liquid outlet pipe, and the bottom side of the oil tank is connected to a slag discharge pipe.

[0017] This system includes an outlet pipe that transports the purified liquid from the bottom of the regenerated liquid tank to the regenerated liquid storage tank, preventing the floating oil from mixing in; and a sludge discharge pipe that regularly discharges the oil sludge and impurities deposited at the bottom of the oil tank, maintaining the processing capacity of the separation tank.

[0018] Preferably, the disinfection component is an ultraviolet disinfection lamp, one side of the regenerated liquid storage tank is connected to an inlet, the inlet is connected to an outlet pipe, the other side of the regenerated liquid storage tank is connected to an outlet, and the outlet is returned to the cutting fluid storage device through a pipeline.

[0019] This device is equipped with ultraviolet disinfection lamps, which use ultraviolet light to destroy the DNA structure of bacteria and microorganisms in the regenerated solution, thus achieving sterilization. The inlet and outlet are connected to the separation tank and the cutting fluid storage equipment to form a circulation loop, allowing the regenerated solution to be reused in machining.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In this integrated circulating purification and regeneration device for machining cutting fluid, the filtration assembly adopts a multi-layered impurity interception system, consisting of a coarse filter chamber, a fine filter chamber, and a magnetic filter connected in series. The coarse filter quickly intercepts large particles of impurities in waste cutting fluid, preventing them from clogging subsequent filtration channels; the fine filter further filters fine particles of impurities, ensuring the cleanliness of the cutting fluid; and the magnetic filter efficiently adsorbs ferromagnetic impurities, showing particularly outstanding performance in treating cutting fluids containing a large amount of metal machining debris. Compared to single filtration methods, this multi-stage filtration approach greatly improves the removal capacity for impurities of different types and particle sizes, ensuring the purity of the purified cutting fluid and meeting the stringent quality requirements of high-precision machining.

[0022] The dissolved gas tank and separation tank in the oil-gas separation unit work together to achieve highly efficient oil-gas separation. The dissolved gas tank introduces gas through an inlet pipe, and the rotation of the stirring rod and blades thoroughly mixes the gas with the cutting fluid, forming microbubbles. These bubbles effectively adhere to the surface of oil droplets, causing them to float. A baffle in the separation tank divides the space into a regenerated fluid tank and an oil tank. The distributor ensures uniform dispersion of the dissolved cutting fluid, extending the oil-water separation time. Combined with the overflow design, this further improves the separation efficiency of oil and cutting fluid, resulting in a more thorough removal of oil contaminants from the cutting fluid compared to traditional separation methods.

[0023] The device adopts an integrated design, organically combining functional modules such as filtration components, oil-gas separation units, and regenerated liquid storage tanks. The overall structure is compact, occupies a small area, and is easy to install and arrange. Compared to similar devices with complex structures on the market, this device reduces unnecessary connecting parts and redundant structures, lowering the probability of equipment failure. During routine maintenance, staff can more easily inspect, clean, and repair each component, effectively reducing maintenance costs and difficulty.

[0024] The ultraviolet (UV) sterilization lamps installed on top of the regenerated fluid storage tank can sterilize and disinfect the purified cutting fluid. UV sterilization is highly efficient and produces no secondary pollution. It can quickly inactivate bacteria and microorganisms that thrive in the cutting fluid, preventing deterioration and foul odor caused by bacterial growth. This ensures the hygiene, safety, and performance of the regenerated fluid, extends its service life, and allows it to continuously and stably perform its cooling, lubrication, and cleaning functions during machining.

[0025] This integrated device enables the recycling, purification, and regeneration of cutting fluid, allowing previously discarded cutting fluid to be treated and then returned to the cutting fluid storage equipment for reuse. This not only reduces the amount of new cutting fluid that companies need to purchase, lowering production costs, but also avoids the pollution of soil, water bodies, and other ecological environments caused by the direct discharge of waste cutting fluid. It aligns with the concepts of green environmental protection and sustainable development, and has significant economic and social benefits. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides an integrated device for circulating, purifying, and regenerating machining cutting fluid, such as... Figure 1 As shown, it includes a cutting fluid collection tank 1, a filter assembly 2 connected to one side of the cutting fluid collection tank 1, an oil-gas separation component connected to one end of the filter assembly 2, the oil-gas separation component includes a dissolved gas tank 3 and a separation tank 4, a regenerated liquid storage tank 5 connected to one side of the oil-gas separation component, and a disinfection component 51 installed on the top inner wall of the regenerated liquid storage tank 5.

[0033] Waste cutting fluid generated during machining is collected in the cutting fluid collection tank 1. After solid impurities are removed by the filter assembly 2, it enters the oil-gas separation component, which consists of a dissolved gas tank 3 and a separation tank 4, to separate oil contaminants. The finally purified regenerated fluid is stored in the regenerated fluid storage tank 5, where a disinfection component 51 sterilizes the regenerated fluid, achieving recycling. Integrated design: Integrates filtration, oil-gas separation, storage, and disinfection functions, simplifying the process and reducing equipment footprint. Recycling: Waste cutting fluid can be reused after treatment, reducing production costs, reducing industrial wastewater discharge, and meeting environmental protection requirements.

[0034] In this embodiment, as Figure 1 As shown, the filter assembly 2 includes a coarse filter chamber 21, a fine filter chamber 22, and a magnetic filter 23 connected in series. The coarse filter chamber 21 is equipped with a coarse filter screen to intercept large particulate impurities in the waste cutting fluid. The fine filter chamber 22 is equipped with a fine filter screen to filter fine particulate impurities in the waste cutting fluid. The magnetic filter 23 is used to adsorb ferromagnetic impurities in the waste cutting fluid.

[0035] Filter assembly 2 employs a three-stage filtration system: the coarse filter in coarse filter chamber 21 intercepts large particles such as metal fragments and fibers, reducing the load on subsequent fine filtration. The fine filter in fine filter chamber 22 filters fine particles such as micron-sized impurities, further improving liquid clarity. The magnetic filter 23 utilizes a magnetic field to adsorb ferromagnetic impurities such as iron and nickel particles, specifically removing magnetic contaminants. This tiered filtration process filters from large particles to fine particles and magnetic impurities layer by layer, improving filtration efficiency and precision, ensuring low impurity content in the liquid entering subsequent treatment stages. It also extends equipment lifespan by reducing wear on downstream components such as dissolved air tank 3 and separation tank 4, thus improving the overall stability of the system.

[0036] Specifically, such as Figure 2As shown, the dissolved gas tank 3 is externally connected to an air inlet pipe 34, the drain end of the filter assembly 2 is connected to the dissolved gas tank 3 through a pipeline, and one side of the dissolved gas tank 3 is connected to the separation tank 4 through a discharge pipe 35. A feed pump is installed on the discharge pipe 35.

[0037] The filtered liquid enters the dissolved air tank 3 through a pipeline, and air or other gases are introduced through its external air inlet pipe 34 to form dissolved air water. The dissolved air water is pressurized by a feed pump on the discharge pipe 35 and then transported to the separation tank 4. The microbubbles generated during dissolved air release adsorb oil droplets and suspended solids in the liquid, causing them to float to the surface for separation. High-efficiency air flotation separation: The dissolved air tank 3 provides ample dissolved air water, allowing oil contaminants to combine with the bubbles and float rapidly, resulting in high separation efficiency. It is suitable for removing emulsified oil and micro-oil droplets. Controllable power: The feed pump adjusts the flow rate to adapt to different processing loads, ensuring a stable separation process.

[0038] Furthermore, such as Figure 2 As shown, a stirring rod 31 is vertically arranged inside the dissolved gas tank 3, and several stirring blades 32 are installed on the outer wall of the stirring rod 31. The top of the stirring rod 31 is driven to rotate by the stirring motor 33.

[0039] The stirring rod 31 inside the dissolved gas tank 3 is driven to rotate by the stirring motor 33, which in turn drives the stirring blades 32 to agitate the liquid, accelerating gas dissolution and forming a uniform dissolved gas water. This enhances dissolved gas efficiency: mechanical stirring promotes gas-liquid mixing, shortens the dissolved gas time, increases the amount of dissolved gas per unit volume, and enhances the subsequent air flotation separation effect. It also prevents sedimentation: stirring avoids the deposition of solid impurities at the bottom of the tank, maintaining the uniformity of the fluid within the tank.

[0040] Furthermore, such as Figure 2 As shown, a vertical partition 41 is installed inside the separation tank 4. An overflow port 42 is provided on the partition 41. The partition 41 divides the interior of the separation tank 4 into a regenerated liquid tank and an oil tank. A distributor 43 is installed on the upper part of the regenerated liquid tank. The inlet of the distributor 43 is connected to the discharge pipe 35. Several small distribution holes with downward openings are provided at the bottom of the distributor 43.

[0041] The separator 4 is divided into a regenerated liquid tank and an oil tank by a baffle 41. A distributor 43 evenly disperses the dissolved air water into fine streams, ensuring full contact between the air bubbles and oil droplets, while the floating oil sludge accumulates in the oil tank. An overflow port 42 allows the purified liquid to overflow from the regenerated liquid tank to the other side of the oil tank, achieving liquid-sludge separation. The small holes in the distributor 43 ensure even distribution of the dissolved air water, improving the flotation effect. The baffle 41 and overflow port 42 effectively isolate the oil sludge from the regenerated liquid, preventing secondary pollution. The structure is compact: a single tank provides dual-function separation and temporary storage, simplifying equipment layout.

[0042] Furthermore, such as Figure 1 , Figure 2As shown, the bottom of one side of the regenerated liquid tank is connected to the regenerated liquid storage tank 5 through the liquid outlet pipe 44, and the bottom of one side of the oil tank is connected to the slag discharge pipe 45.

[0043] The outlet pipe 44 transports the purified liquid from the bottom of the regenerated liquid tank to the regenerated liquid storage tank 5, preventing the upper floating oil from mixing in; the sludge discharge pipe 45 regularly discharges the oil sludge and impurities deposited at the bottom of the oil tank, maintaining the processing capacity of the separation tank 4. High purity of the regenerated liquid: bottom sampling ensures avoidance of the floating oil layer, improving the quality of the regenerated liquid; convenient maintenance: the sludge discharge pipe 45 facilitates regular cleaning, preventing oil sludge accumulation from affecting separation efficiency.

[0044] Furthermore, such as Figure 3 As shown, the disinfection component 51 uses an ultraviolet disinfection lamp. One side of the regenerated liquid storage tank 5 is connected to an inlet 52, which is connected to an outlet pipe 44. The other side of the regenerated liquid storage tank 5 is connected to an outlet 53, which is returned to the cutting fluid storage device through a pipeline.

[0045] The ultraviolet disinfection lamp 51 sterilizes the regenerated fluid by destroying the DNA structure of bacteria and microorganisms through ultraviolet irradiation. The inlet 52 connects to the outlet pipe 44, and the outlet 53 connects to the cutting fluid storage equipment through a pipeline, forming a circulation loop that allows the regenerated fluid to be reused in machining. Hygiene and safety: Disinfection treatment prevents the growth of microorganisms in the circulating cutting fluid, avoiding odors and equipment corrosion. Closed-loop circulation: The regenerated fluid is directly returned to the production system, reducing the amount of new fluid replenishment, lowering costs, and reducing environmental impact.

[0046] When the integrated machine cutting fluid circulation purification and regeneration device of this utility model is in use, the waste cutting fluid generated during the machining process is first collected into the cutting fluid collection tank 1. This collection tank serves as an initial storage unit, providing raw material reserves for subsequent processing and temporarily storing waste cutting fluid containing impurities such as metal scraps, oil stains, and microorganisms.

[0047] The collected waste cutting fluid flows from the cutting fluid collection tank 1 into the filter assembly 2 for three-stage filtration:

[0048] Coarse filtration: In the coarse filtration chamber 21, the coarse filter screen intercepts large particulate impurities, such as metal shavings and fibers, to initially purify the cutting fluid and reduce the pressure on subsequent filtration.

[0049] Fine filtration: The cutting fluid that has passed the coarse filtration enters the fine filtration chamber 22, where the fine filter screen further filters out micron-sized fine particulate impurities, improving the clarity of the liquid.

[0050] Magnetic adsorption: Finally, the cutting fluid flows through the magnetic filter 23, where the magnetic field adsorbs ferromagnetic impurities, such as iron and nickel particles, ensuring that the impurity content of the cutting fluid entering the next stage is greatly reduced.

[0051] The filtered cutting fluid enters the dissolved gas tank 3 through a pipeline for oil-gas separation.

[0052] Dissolving process: Air or other gases are introduced into the dissolving tank 3 through the air inlet pipe 34. At the same time, the stirring motor 33 drives the stirring rod 31 and stirring blade 32 to rotate, accelerating the mixing of gas and liquid to form uniform dissolved water, so that the gas is fully dissolved in the cutting fluid.

[0053] Air flotation separation: Dissolved air water is pressurized by a pump on discharge pipe 35 and then transported to separation tank 4. In separation tank 4, distributor 43 evenly disperses the dissolved air water into fine streams. The air bubbles in the dissolved air water release and adsorb oil droplets and suspended solids, causing them to float to the surface. Baffle 41 divides separation tank 4 into a regeneration liquid tank and an oil tank. The floating oil sludge accumulates in the oil tank, while the purified liquid overflows from the regeneration liquid tank to the other side through overflow port 42, achieving effective separation of oil and impurities.

[0054] The separated purified regenerated fluid flows from the bottom of the regenerated fluid tank in the separation tank 4 into the regenerated fluid storage tank 5 through the outlet pipe 44, preventing the upper floating oil from mixing in and ensuring the purity of the regenerated fluid. At the same time, the ultraviolet disinfection lamp 51 installed on the inner wall of the top of the regenerated fluid storage tank 5 irradiates the regenerated fluid, using ultraviolet light to destroy the DNA structure of bacteria and microorganisms, kill harmful microorganisms, and prevent the cutting fluid from deteriorating and smelling bad during storage and recycling.

[0055] The disinfected regenerated fluid is transported back to the cutting fluid storage equipment through the outlet 53 of the regenerated fluid storage tank 5 via pipeline, and then put back into machining production. This completes the closed-loop cycle of cutting fluid from collection and purification to reuse, realizing the reuse of resources and reducing the company's production costs and environmental burden.

[0056] Finally, it should be noted that the electronic components in the distributor 43 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order of each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
