Technical Field
[0001] This utility model relates to the fields of machining and environmental protection technology, specifically to a cutting fluid recovery device. Background Technology
[0002] Cutting fluid plays a crucial role in machining processes, including lubrication, cooling, cleaning, and rust prevention. Its performance directly affects machining efficiency and workpiece surface quality. With increasingly stringent environmental requirements and growing awareness of resource conservation, the recycling and reuse of cutting fluids has become an important issue in the machining field. However, existing cutting fluid recovery devices still have certain limitations in practical applications, particularly in terms of recovery efficiency, filtration accuracy, ease of operation, and protection of cutting fluid performance.
[0003] A cutting fluid filtration device, disclosed in CN105413292B, utilizes a cleaning mechanism and a filtration mechanism. It removes impurities from the filter screen using scrapers, adsorption balls, and adsorption blades, achieving filtration through a ring-shaped filter screen. However, in this technical solution, the cleaning of the filter screen relies primarily on mechanical scraping and adsorption, which may leave fine particles behind, increasing the risk of clogging. Furthermore, the cleaning mechanism is relatively complex, leading to higher maintenance costs and operational difficulties. It also provides insufficient protection for the chemical components in the cutting fluid, potentially affecting its lubrication and rust prevention performance.
[0004] Another cutting fluid circulation device, disclosed in CN104589152B, uses a float to control the opening and closing of the connecting pipe, combined with a slide pipe and a spring mechanism to achieve the circulation of cutting fluid. This technical solution can improve the utilization rate of cutting fluid, but its magnet and spring design may experience wear or failure during long-term operation. Furthermore, this device does not adequately consider the separation and removal of impurities in the cutting fluid, which may lead to residual particles in the circulating fluid damaging the workpiece's machined surface and affecting machining quality.
[0005] The aforementioned problems indicate that existing cutting fluid recovery devices still have room for improvement in terms of filtration accuracy, cleaning effect, equipment reliability, and protection of cutting fluid performance. Therefore, it is necessary to design a new type of cutting fluid recovery device to optimize filtration and cleaning functions, simplify equipment structure, extend the service life of the cutting fluid, and improve recovery efficiency, thereby meeting the modern industrial demand for efficient and environmentally friendly cutting fluid recovery.

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0034] This utility model provides a cutting fluid recovery device, combined with the attached... Figures 1 to 6 The specific implementation of this device will be described in detail below. The device includes a recovery tank 1, a separation mechanism, and a circulation mechanism. The efficient cutting fluid recovery function is achieved through a rational structural design among the components. The following will describe the components and their interconnections in detail with reference to the accompanying drawings.
[0035] The recovery tank 1 is the main body of the overall device, with an inlet 2 at the top and an outlet 3 at the bottom. The inlet 2 receives cutting fluid containing impurities, while the outlet 3 discharges the treated cutting fluid. An internal separation mechanism is located within the recovery tank 1, fixedly connected to the inner wall of the tank via a bracket to ensure stability during operation. The core component of the separation mechanism is a filter cartridge 4, whose two ends are rotatably connected to the inner wall of the recovery tank 1 via bearings, allowing for rotation. The outer wall of the filter cartridge 4 has multiple evenly distributed filter holes for preliminary filtration of the cutting fluid. The drive assembly includes a motor 5 and a transmission gear 6. The motor 5 is fixedly mounted on the outer wall of the recovery tank 1, and the transmission gear 6 meshes with one end of the filter cartridge 4. When the motor 5 starts, the transmission gear 6 drives the filter cartridge 4 to rotate, thus achieving dynamic filtration of the cutting fluid.
[0036] The filter cartridge 4 is equipped with a cleaning assembly consisting of a scraper 7 and a guide plate 8. The scraper 7 is arranged axially along the filter cartridge 4 and slides in contact with the inner wall of the filter cartridge 4, continuously removing impurities adhering to its inner wall as the filter cartridge 4 rotates. The guide plate 8 is fixedly installed on the inner wall of the filter cartridge 4, and its inclination direction is consistent with the rotation direction of the filter cartridge 4, used to guide impurities in the cutting fluid to move towards one end of the filter cartridge 4. To further optimize the impurity collection effect, a guide groove 9 is installed on the inner wall of the recovery tank 1. The guide groove 9 is arranged axially along the filter cartridge 4, and its opening faces the outer wall of the filter cartridge 4. A slag collection tank 10 is provided at the bottom of the guide groove 9. The slag collection tank 10 is connected to the outside of the recovery tank 1 through a slag discharge pipe 11, used to collect and discharge impurities that fall off the surface of the filter cartridge 4.
[0037] The circulation mechanism is located outside the recovery tank 1 and includes a pump body 12 and a distributor 13. The inlet of the pump body 12 is connected to the outlet 3 of the recovery tank 1 via a pipe, and the outlet is connected to the inlet of the distributor 13 via a pipe. The outlet of the distributor 13 is divided into two paths: one path is connected to the top of the recovery tank 1 via a return pipe 14, and the other path is connected to external processing equipment via a delivery pipe 15. An adjusting plate 16 is provided inside the distributor 13. The adjusting plate 16 is rotatably connected to the inner wall of the distributor 13 via a rotating shaft 17. One end of the rotating shaft 17 extends to the outside of the distributor 13 and is equipped with a handle 18. By manually adjusting the position of the handle 18, the angle of the adjusting plate 16 can be changed, thereby adjusting the flow ratio of the return pipe 14 and the delivery pipe 15 to meet the needs of different working conditions.
[0038] An exhaust pipe 19 is installed on the top of the recovery tank 1. One end of the exhaust pipe 19 is connected to the interior of the recovery tank 1, and the other end is equipped with a one-way valve 20. The one-way valve 20 opens towards the outside of the recovery tank 1 to promptly discharge the gas inside the recovery tank 1, preventing excessive air pressure from affecting the flow of cutting fluid and the filtration effect. Multiple raised strips 21 are provided on the outer wall of the filter cartridge 4. The raised strips 21 are arranged along the axial direction of the filter cartridge 4 and are integrally formed with the outer wall of the filter cartridge 4. Multiple grooves are provided on the surface of the raised strips 21. These grooves increase the flow path of the cutting fluid on the surface of the filter cartridge 4, thereby improving the filtration effect.
[0039] A baffle 22 is installed on the inner wall of the recovery tank 1. The baffle 22 is located below the filter cartridge 4 and maintains a certain gap with the outer wall of the filter cartridge 4. The inclination direction of the baffle 22 is opposite to the rotation direction of the filter cartridge 4, which can effectively prevent the cutting fluid from directly impacting the outer wall of the filter cartridge 4 and reduce the wear of the filter cartridge 4. The bottom of the recovery tank 1 is provided with an inclined surface 23, and the lowest point of the inclined surface 23 is connected to the drain port 3. Multiple guide vanes 24 are installed on the inclined surface 23. The guide vanes 24 are arranged along the length of the inclined surface 23 to guide the cutting fluid to flow to the drain port 3 and reduce the residence time of the cutting fluid at the bottom of the recovery tank 1. One end of the filter cartridge 4 is provided with a sealing cap 25. The sealing cap 25 is fixedly connected to the end of the filter cartridge 4 by bolts. A sealing ring is provided on the inner side of the sealing cap 25. The sealing ring fits tightly with the end of the filter cartridge 4 to prevent the cutting fluid from leaking from the end of the filter cartridge 4.
[0040] In actual operation, the cutting fluid containing impurities enters the recovery tank 1 through the inlet 2 and then flows into the rotating filter cartridge 4. The rotation of the filter cartridge 4 causes the cutting fluid to diffuse outward under the action of centrifugal force. Impurities in the cutting fluid are trapped on the outer wall of the filter cartridge 4, while the liquid enters the internal space of the recovery tank 1 through the filter holes. The scraper 7 continuously cleans the impurities on the inner wall of the filter cartridge 4 as it rotates, while the guide plate 8 guides the impurities to one end of the filter cartridge 4, and finally falls into the slag collection tank 10 through the guide groove 9 and is discharged through the slag discharge pipe 11. The cutting fluid that has undergone preliminary filtration accumulates at the bottom of the recovery tank 1 and is then pumped by the pump body 12 and sent to the distributor 13. The operator adjusts the position of the regulating plate 16 in the distributor 13 through the handle 18 according to actual needs, thereby controlling the flow ratio of the return pipe 14 and the delivery pipe 15. A portion of the cutting fluid returns to the recovery tank 1 through the return pipe 14 for reprocessing, while the other portion is transported to external processing equipment for reuse through the delivery pipe 15.
[0041] During operation, the design of the exhaust pipe 19 and the one-way valve 20 ensures stable air pressure inside the recovery tank 1, preventing obstruction of cutting fluid flow or decreased filtration efficiency due to excessive air pressure. Simultaneously, the design of the baffle 22 reduces the direct impact of cutting fluid on the outer wall of the filter cartridge 4, decreasing wear and improving filtration efficiency. The arrangement of the guide vanes 24 further optimizes the flow path of the cutting fluid at the bottom of the recovery tank 1, reducing its residence time and preventing performance degradation due to prolonged retention. The design of the sealing cap 25 and the sealing ring ensures the airtightness of the filter cartridge 4, preventing cutting fluid leakage that could lead to resource waste or environmental pollution.
[0042] Through the above structural design and operating principle, this device achieves a highly efficient and stable cutting fluid recovery function, solving the problems of insufficient filtration accuracy, poor cleaning effect, high equipment complexity, and insufficient protection of cutting fluid performance in the existing technology.
[0043] To enable those skilled in the art to fully understand and implement this utility model, the following detailed explanation of the implementation principle of this utility model is provided in conjunction with a specific application scenario.
[0044] In machining workshops, cutting fluid recovery devices are installed next to machine tools to treat cutting fluid containing impurities discharged from the machines. This device achieves efficient filtration, impurity separation, and cutting fluid recycling through a series of structural designs and operational procedures.
[0045] First, cutting fluid containing impurities such as metal shavings and oil enters the recovery tank 1 through the inlet 2. The cutting fluid flows into the rotating filter cartridge 4, at which point the motor 5 starts and drives the filter cartridge 4 to rotate at high speed via the transmission gear 6. Due to centrifugal force, the liquid portion of the cutting fluid passes through the filter holes on the outer wall of the filter cartridge 4 into the interior space of the recovery tank 1, while larger solid impurities are trapped on the outer wall of the filter cartridge 4. This process, based on the principle of centrifugal separation, effectively prevents fine particles from clogging the filter holes, thereby improving filtration efficiency. Simultaneously, the raised strips 21 on the outer wall of the filter cartridge 4 further increase the flow path of the cutting fluid on its surface, making the separation between the liquid and impurities more thorough.
[0046] Secondly, during the rotation of the filter cartridge 4, the internal scraper 7 continuously removes residual impurities adhering to the inner wall of the filter cartridge 4. Guided by the guide plate 8, these impurities move towards one end of the filter cartridge 4 and eventually fall into the slag collection tank 10 through the guide groove 9. Subsequently, the impurities in the slag collection tank 10 are discharged into an external collection container through the slag discharge pipe 11. This step ensures that the filter cartridge 4 remains clean at all times, preventing a decrease in filtration efficiency or equipment malfunction due to impurity accumulation. Furthermore, the design of the baffle 22 effectively prevents cutting fluid from directly impacting the outer wall of the filter cartridge 4, reducing wear and extending its service life.
[0047] After initial filtration, the cutting fluid accumulates at the bottom of the recovery tank 1 and flows along the inclined surface 23 to the drain port 3. During this process, the guide vanes 24 play a crucial role; arranged along the inclined surface 23, they optimize the flow path of the cutting fluid, reducing its residence time at the bottom and thus preventing performance degradation due to prolonged stagnation. When the cutting fluid passes through the drain port 3, the pump 12 draws it in and sends it to the distributor 13. The operator manually adjusts the position of the handle 18 according to actual needs, changing the angle of the adjusting plate 16 inside the distributor 13, thereby controlling the flow ratio between the return pipe 14 and the delivery pipe 15. A portion of the cutting fluid returns to the recovery tank 1 through the return pipe 14 for reprocessing, while the other portion is delivered to external processing equipment for reuse through the delivery pipe 15. This flexible flow distribution mechanism meets the cutting fluid requirements under different operating conditions.
[0048] Throughout the operation, the design of the exhaust pipe 19 and the one-way valve 20 plays a crucial role. When gas is generated inside the recovery tank 1, the one-way valve 20 automatically opens, venting the gas to the external environment and maintaining stable internal pressure. This not only ensures smooth flow of the cutting fluid but also prevents external contaminants from entering the recovery tank 1 through the exhaust pipe 19, ensuring the quality of the cutting fluid. Simultaneously, the fit between the sealing cap 25 and the sealing ring ensures the airtightness of the filter cartridge 4, preventing cutting fluid leakage that could lead to resource waste or environmental pollution.
[0049] Through the above steps and principles, the cutting fluid recovery device of this invention achieves efficient impurity separation, stable filtration effect, and reliable recycling function. The coordinated operation of all components solves the problems of insufficient filtration accuracy, poor cleaning effect, high equipment complexity, and inadequate protection of cutting fluid performance in existing technologies, providing a practical solution for the machining field.
[0050] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
