Description

Technical Field

[0001] This application relates to the technical field of cutting fluid purification equipment, and in particular to a cutting fluid recovery and purification mechanism for tricycle processing. Background Technology

[0002] Cutting fluids are mainly divided into water-based cutting fluids and oil-based cutting fluids. They are commonly used in metal cutting, grinding and other machining processes. Their main functions are: to absorb the heat generated during the cutting process and reduce the temperature of the tool and workpiece; to form a lubricating film between the tool, workpiece and chips, reduce the coefficient of friction and reduce the cutting force; to flush away chips, grinding debris and other impurities generated during the cutting process and prevent them from entering between the tool and workpiece; and to form a protective film on the metal surface to prevent the workpiece and machine tool from rusting.

[0003] Water-based cutting fluids are commonly used in tricycle manufacturing. To reduce production costs, it is necessary to recycle and purify these fluids. Impurities in water-based cutting fluids mainly include metal shavings and abrasive particles of varying sizes, microorganisms, oil impurities, ionic impurities, and suspended impurities, requiring different treatment processes for effective removal. Existing water-based cutting fluid recycling and purification facilities with large processing capacities and high precision often suffer from low equipment efficiency and large space requirements due to the numerous processing steps. Furthermore, clogged components and the high content of various impurities, especially small-particle impurities, can make the backwashing process cumbersome.

[0004] Therefore, how to design a cutting fluid recovery and purification mechanism for tricycle processing that has both high processing capacity and efficiency, small footprint, and convenient and quick backwashing has become the problem we need to solve. Summary of the Invention

[0010] By adopting the above technical solution, this utility model has at least one of the following beneficial effects compared with the prior art: 1.

During filtration and backwashing, the spiral plate has a certain cleaning effect on the inner side of the filter cartridge and the inlet end of the multi-layer filter plate.

[0013] To better understand the technical solutions shown in the embodiments of this application, the working principle of existing water-based cutting fluid recovery and purification equipment will first be introduced: The water-based cutting fluid is first pressurized by a booster pump. The pressurized fluid then flows through the inlet pipe into the primary filtration unit. As the fluid passes through the filter screen, larger metal chips, abrasive particles, and suspended impurities are trapped on the screen surface. The filtered fluid exits the filter unit and enters another booster pump for secondary pressurization. The pressurized fluid then flows into the deep filtration unit, where it first passes through a rectifier grid for flow correction. The rectified fluid then flows to the nanofiltration membrane, where oil impurities, some ionic impurities, and microorganisms are trapped on and inside the membrane. The filtered fluid is then discharged through the outlet pipe. If the filter screen or nanofiltration membrane becomes clogged, the primary or deep filtration unit must be removed for backwashing.

[0014] Existing water-based cutting fluid recovery and purification equipment suffers from low processing efficiency, large space requirements, and cumbersome backwashing procedures when filters or nanofiltration membranes become clogged. This invention presents a cutting fluid recovery and purification mechanism for tricycle machining that offers both high processing capacity and efficiency, a smaller footprint, and convenient and quick backwashing.

[0015] Please see Figures 1 to 5 This utility model provides a technical solution: a cutting fluid recovery and purification mechanism for tricycle processing, including a support plate 1, a purification mechanism 2, a drive mechanism 3, a fixing plate 4, an upper cover plate 5, a liquid inlet pipe 6, a slag discharge pipe 7, an oil discharge pipe 8, and a liquid outlet pipe 9.

[0016] like Figure 1As shown, the purification mechanism 2 includes a spiral plate A21, a pusher plate 22, a spiral plate B23, a housing 24, a filter cartridge 25, a flow rectifier grid 26, a multi-layer filter plate 27, a liquid outlet chamber 28, and a liquid separator 29. The housing 24 is fixedly connected to the upper surface of the edge of the support plate 1, and the filter cartridge 25 is fixedly connected to the upper surface of the middle position of the support plate 1. The filter cartridge 25 is made of stainless steel and has a filter screen with a pore size of 0.5 to 1 mm. The function of the filter cartridge 25 is to remove larger metal chips, abrasive particles, and suspended impurities from the cutting fluid. The fixing plate 4 is fixedly connected to the upper end of the housing 24, and the fixing plate 4 has a pusher rod groove 41 for the pusher rod 221 to move. The upper end of the spiral plate A21 is rotatably connected to the lower surface of the fixed plate 4 in the middle position. The spiral plate A21 not only imparts speed to the cutting fluid to filter the filter cartridge 25, but also transports the debris to the bottom of the filter cartridge 25 in a timely manner, thus slowing down the process of debris clogging the filter cartridge 25. The outer diameter of the spiral plate A21 is similar to the inner diameter of the filter cartridge 25, which can clean the debris accumulated on the inside of the filter cartridge 25.

[0017] like Figure 5 As shown, the liquid diaphragm 29 is fixedly connected within the annular cavity formed by the outer shell 24 and the filter cartridge 25. The liquid diaphragm 29 contains the flow-rectifying grid 26, the spiral plate B23, and the multi-layer filter plate 27. The liquid diaphragm 29 is made of an elastic liquid-blocking material. The top view of the liquid diaphragm 29 consists of a semi-circle and fan-shaped rings that fit the outer side of the filter cartridge 25 and the inner side of the outer shell 24. The straight edge of the semi-circle coincides with the generatrix of the fan-shaped rings. The inlet side of the liquid diaphragm 29 is set as a semi-circle to fit the shape of the flow-rectifying grid 26. The purpose of setting the fan-shaped rings on both sides of the liquid diaphragm 29 is to allow the liquid diaphragm 29 to fit tightly against the inner side of the outer shell 24 and the outer side of the filter cartridge 25, preventing cutting fluid from flowing out from the gap between the liquid diaphragm 29 and the outer side of the filter cartridge 25, and between the liquid diaphragm 29 and the inner side of the outer shell 24 during the movement of the pusher plate 22. This would reduce the amount of water passing through the multi-layer filter plate 27 and cause a large amount of cutting fluid to accumulate on the rear side of the pusher plate 22, resulting in greater resistance when the pusher plate 22 returns to its original position. The function of the liquid diaphragm 29 is to restrict the direction of water flow through the rectifier grid 26, the multi-layer filter plate 27, and the outlet chamber 28, ensuring stable water flow within the liquid diaphragm 29 and preventing cutting fluid from seeping out from one side of the filter cartridge 25 during the movement of the pusher plate 22. This would cause the cutting fluid to generate vortices and turbulent flow before passing through the multi-layer filter plate 27, thus affecting the filtration of the multi-layer filter plate 27. On the other hand, the liquid diaphragm 29 ensures the stability of the material of the internal cutting fluid, preventing cutting fluid that has not been filtered by the multi-layer filter plate 27 from entering the outlet chamber 28. The liquid diaphragm 29 also restricts the flow of backwash water during backwashing.

[0018] like Figure 5As shown, the rectifier grid 26 is fixedly connected to the upper surface of the support plate 1 corresponding to the inlet position of the liquid separator 29. The inlet direction of the rectifier grid 26 is consistent with the inlet direction of the liquid separator 29. The rectifier grid 26 is composed of a series of concentric fan rings and coaxial fan rings with very small widths. The concentric fan rings and coaxial fan rings are combined to form a large number of rectifier grids with very small areas. The top view of the rectifier grid 26 is composed of a semi-circle and fan rings that fit the inner side of the liquid separator 29. The straight edge of the semi-circle coincides with the generatrix of the fan ring. The purpose of setting the inlet side of the rectifier grid 26 as a semi-circle is to optimize the water flow distribution, so that the water flow can pass through the rectifier grid 26 more evenly. It can also significantly reduce the resistance when the water flows through, reduce the wear and corrosion caused by the water flow, and enhance the structural stability of the rectifier grid 26. The two sides of the rectifier grid 26 are set as fan rings to fit the inner side of the liquid separator 29 to prevent unrectified cutting fluid from disturbing the water flow. The function of the rectifier bar 26 is to eliminate eddies and turbulent flow in the water flow, so that the water flow is evenly distributed, which is beneficial to the filtration process of the multi-layer filter plate 27.

[0019] like Figure 5 As shown, the upper end of the spiral plate B23 is rotatably connected to the lower surface of the fixed plate 4 near the outlet of the rectifier grid 26. The spiral plate B23 can transport the oil sludge to the bottom of the spiral plate B23 in a timely manner, slowing down the process of oil sludge clogging the multi-layer filter plate 27. The outer diameter of the spiral plate B23 is similar to the width of the multi-layer filter plate 27, which can clean the oil sludge accumulated on the inlet side of the multi-layer filter plate 27. The spiral plate B23 has a large pitch, so the degree of disturbance to the water flow is very low. The multi-layer filter plate 27 is fixedly connected to the upper surface of the support plate 1 on the opposite side of the spiral plate B23. The inlet direction of the multi-layer filter plate 27 is consistent with the inlet direction of the liquid separator 29. The multi-layer filter plate 27 is composed of a multi-layer nanofiltration plate made of polyamide material with a pore size of 1-1000 micrometers, arranged from large to small pore size. The top view of the multi-layer filter plate 27 is composed of a semi-circle and a fan-shaped ring that fits the inner side of the liquid separator 29. The straight edge of the semi-circle coincides with the generatrix of the fan-shaped ring. The purpose of setting the inlet side of the multi-layer filter plate 27 as a semi-circle is to make the water flow evenly distributed on the multi-layer filter plate 27, reduce the dead zone of the water flow, smooth the flow, improve the water flow capacity, stabilize the water flow, prevent the flow deviation, and reduce the wear of the multi-layer filter plate 27. The fan-shaped rings on both sides of the multi-layer filter plate 27 fit the inner side of the liquid separator 29 to prevent unfiltered cutting fluid from entering the outlet chamber 28. The function of the multi-layer filter plate 27 is to remove oil impurities, some ionic impurities, and microorganisms. The outlet side of the multi-layer filter plate 27 and the tail of the liquid separator 29 form a liquid outlet chamber 28. The cutting fluid filtered by the multi-layer filter plate 27 is discharged from the liquid outlet pipe 9 at the bottom of the liquid outlet chamber 28.

[0020] like Figure 4As shown, the push plate 22 includes a push plate rod 221, a support plate 222, and an arc-shaped plate 223. The end of the push plate rod 221 is fixedly connected to the other end of the lever arm 326. The support plate 222 is fixedly connected to the arc-shaped plate 223. The support plate 222 prevents the arc-shaped plate 223 from deforming due to water flow resistance and friction on both sides. The support plate 222 is fixedly connected to the push plate rod 221. The top view of the arc-shaped plate 223 consists of a semi-circle and a fan-shaped ring that fits the outer side of the filter cartridge 25 and the inner side of the outer shell 24. The circular straight edge coincides with the generatrix of the fan ring. The purpose of setting the water-facing surface of the arc plate 223 as a semi-circle is to make the water flow more smoothly, reduce turbulence and eddies in the water flow, and reduce the resistance of the water flow to the push plate 22. At the same time, it makes the force distribution more uniform when the push plate 22 pushes the water flow, avoids excessive local pressure, and improves the stability of the push plate 22's movement. The arc-shaped water-facing surface helps guide the water flow to form a more regular flow pattern, reducing the scouring effect on the surface of the push plate 22. The two sides of the push plate 22 are set as fan rings to fit the outer side of the filter cartridge 25 and the inner side of the outer shell 24, preventing cutting fluid from flowing out from the gap between the push plate 29 and the outer side of the filter cartridge 25, and between the push plate 22 and the inner side of the outer shell 24 during the movement of the push plate 22. This would reduce the water pressure caused by the push plate 22 and cause a large amount of cutting fluid to accumulate on the rear side of the push plate 22, resulting in greater resistance when the push plate 22 returns to its original position. The outer side of the arc-shaped plate 223 of the push plate 22 is provided with a smooth elastic material liquid-separating plate, which ensures that the arc-shaped plate 223 fits tightly with the outer side of the filter cartridge 25 and the inner side of the outer shell 24 while reducing friction. The tail of the liquid-separating cover 29 can fit tightly with the tail of the push plate 22, reducing the volume of cutting fluid left on the rear side of the push plate 22 and reducing the resistance when the push plate 22 returns to its original position.

[0021] Combination Figure 1 , Figure 2 and Figure 3As shown, the drive mechanism 3 includes a motor A31, a drive module 32, a motor C33, a fixing device A34, a fixing device B35, a drive mechanism housing 36, and a control panel 37. The drive mechanism housing 36 is fixedly connected to the upper surface of the edge of the fixing plate 4, and the upper cover plate 5 is fixedly connected to the upper end of the drive mechanism housing 36. The control panel 37 is fixedly connected to the upper surface of the upper cover plate 5. The motor A31 is fixedly connected to the upper end of the spiral plate A21 corresponding to the upper surface of the fixing plate 4. The end of the output shaft of the motor A31 is fixedly connected to the upper end of the rotating shaft of the spiral plate A21. The motor A31 is a medium-speed, medium-torque motor, driving the spiral plate A21 to rotate at a medium speed and medium torque. The fixing device A34 is fixedly connected to the upper surface of the fixing plate 4 near the middle position, and the fixing device B35 is fixedly connected to the lower surface of the upper cover plate 5 near the edge position. The drive module 32 includes a motor B321, gears A322, B323, C324, D325, and a lever arm 326. Motor B321 is fixedly connected to the upper surface of the fixed device B35. The end of the output shaft of motor B321 is fixedly connected to gear A322. Motor B321 is a high-speed, low-torque motor. Gear B323 is rotatably connected to the lower surface of the fixed device B35. Gear B323 and gear C324 are fixedly connected. The lower surface of one end of the lever arm 326 is rotatably connected to the upper surface of the fixed device A34, and the upper surface of one end of the lever arm 326 is fixedly connected to the lower surface of gear D325. When motor B321 starts, the end of the output shaft of motor B321 drives gear A322 to rotate. Gear A322 meshes with gear B323. The diameter of gear A322 is smaller than the diameter of gear B323. When gear A322 drives gear B323 to rotate, the torque increases and the speed decreases. The diameter of gear B323 is larger than the diameter of gear C324. Since gear B323 and gear C324 are fixedly connected, when gear B323 drives gear C324 to rotate, the speed and torque remain constant, but the gear radius decreases. Gear C324 meshes with gear D325. The diameter of gear C324 is smaller than the diameter of gear D325. When gear C324 drives gear D325 to rotate, the torque increases and the speed decreases. Drive module 32 converts the high-speed, low-torque output of motor B321 into a low-speed, high-torque output, driving push plate 22 to rotate at low speed and high torque. Motor C33 is fixedly connected to the fixed plate 4 corresponding to the upper end of the spiral plate B23. The end of the output shaft of motor C33 is fixedly connected to the upper end of the rotating shaft of spiral plate B23. Motor C33 is a low-speed, low-torque motor that drives spiral plate B23 to rotate at low speed and low torque.

[0022] like Figure 1 and Figure 2As shown, an inlet pipe 6 runs through the fixed plate 4 and the upper cover plate 5 corresponding to the upper end of the spiral plate A21. A slag discharge pipe 7 runs through the supporting plate 1 corresponding to the lower end of the spiral plate A21. An oil discharge pipe 8 runs through the supporting plate 1 corresponding to the lower end of the spiral plate B23. An outlet pipe 9 runs through the supporting plate 1 corresponding to the lower end of the outlet chamber 28. Solenoid valves are installed on the inlet pipe 6, slag discharge pipe 7, oil discharge pipe 8, and outlet pipe 9. The control panel 37 controls the switching of the solenoid valves on the four pipes. The control panel 37 also controls the rotation sequence and speed of the three motors: motor A31, motor B321, and motor C33.

[0023] Working principle of the cutting fluid recovery and purification mechanism for tricycle processing: When the cutting fluid recovery and purification mechanism for tricycle machining is in operation, the control panel 37 controls the solenoid valve switches of four pipes: inlet pipe 6, slag discharge pipe 7, oil discharge pipe 8, and outlet pipe 9. The control panel 37 also controls the rotation sequence and speed of three motors: motor A31, motor B321, and motor C33. Before the cutting fluid recovery and purification mechanism for tricycle machining starts working, the push plate 22 is positioned close to the outlet chamber 28, and the end of the arc-shaped plate 223 is in contact with the end of the outlet chamber 28, so that when the filter cartridge 25 discharges water, there is as little cutting fluid accumulation as possible behind the push plate 22. Open the valves of the inlet pipe 6 and the outlet pipe 9. The cutting fluid is injected into the inside of the filter cartridge 25 through the inlet pipe 6. Start the motor A31 to drive the spiral plate A21 to rotate, pushing the cutting fluid towards the filter cartridge 25 for filtration. The filtered cutting fluid enters the annular cavity formed by the outer side of the filter cartridge 25 and the inner side of the outer shell 24. Larger metal chips, abrasive particles, and suspended impurities remain inside the filter cartridge 25. The rotation of the spiral plate A21 pushes the filter residue inside the filter cartridge 25 to the bottom of the filter cartridge 25. When the liquid levels on both the inner and outer sides of the filter cartridge 25 rise to a certain height and are level, close the valve of the inlet pipe 6 and stop the rotation of the spiral plate A21 driven by the motor A31. Start the motor B321 to drive the pusher plate 22. Since the liquid levels on both the inner and outer sides of the filter cartridge 25 are level, it can be assumed that there is no water flow moving in opposite directions on the inner and outer sides of the filter cartridge 25 in front of the pusher plate 22. The influence of the turbulent flow and vortex generated is very small and can be ignored under the action of the pusher plate 22. Without the rotation of the spiral plate A21, the amount of cutting fluid naturally seeping out of the filter cartridge 25 behind the pusher plate 22 is very small, and the resistance caused by the pusher plate 22 during its return is negligible. Therefore, the volume of cutting fluid in the filter cartridge 25 can be considered constant during the movement of the pusher plate 22. The pusher plate 22 pushes the cutting fluid in the annular cavity towards the rectifier grid 26 with a certain pressure. After the cutting fluid is rectified, it becomes a uniform and stable water flow with a certain pressure. The pitch of the spiral plate B23 is large, and its disturbance effect on the water flow is negligible. When the uniform and stable water flow passes through the multi-layer filter plate 27, the filtered cutting fluid enters the outlet chamber 28. Smaller metal debris and abrasive particles, microorganisms, oil impurities, divalent and polyvalent ions remain on the surface and inside of the multi-layer filter plate 27. The filtered cutting fluid is discharged through the outlet chamber 28 and the outlet pipe 9.

[0024] When pusher plate 22 moves to the edge of rectifier grid 26, the cutting fluid in the liquid separator has been filtered as much as possible, with only a small amount of cutting fluid remaining near spiral plate B23. Reverse start motor B321 drives pusher plate 22 back to its original position, and the next cutting fluid recovery and purification process can begin. When the final process, where the liquid levels on both sides of the filter cartridge are low, is about to be completed, pusher plate 22 does not need to move back to its original position. At this time, a small amount of cutting fluid remains inside the filter cartridge 25 and near spiral plate B23. The valve of outlet pipe 9 is closed, and the valve of slag discharge pipe 7 is opened. The filter slag at the bottom of filter cartridge 25 is carried out by the small amount of cutting fluid inside the filter cartridge 25 and discharged through slag discharge pipe 7. Start motor C33 drives spiral plate B23 to rotate, pushing the oil sludge near it and on the filter plate to the bottom of spiral plate B23. The valve of oil discharge pipe 8 is opened, and the oil sludge at the bottom of spiral plate B23 is carried out by the small amount of cutting fluid remaining near spiral plate B23 and discharged through oil discharge pipe 8. Start motor B321 to drive push plate 22 to move back to its original position, turn off motor C33 to drive spiral plate B23 to stop rotating, and close the valves of slag discharge pipe 7 and oil discharge pipe 8.

[0025] The cutting fluid recovery and purification mechanism for tricycle processing opens the valves of the oil drain pipe 8 and the liquid outlet pipe 9 during backwashing of the filter cartridge 25 and multi-layer filter plate 27. Motor B321 is started, driving the push plate 22 to the edge of the rectifier grid 26 to prevent the chemical agent water from flowing to other positions. Motor C33 is started, driving the spiral plate B23 to rotate. A pressurized chemical agent water flow is connected to the liquid outlet pipe 9, causing the chemical agent water to flow in the opposite direction through the multi-layer filter plate 27. This carries out smaller metal debris, abrasive particles, oil impurities, microorganisms, and divalent and polyvalent ions that are blocked in the multi-layer filter plate 27. The rotation of the spiral plate B23 pushes the oil residue and the backwashed oil residue from the multi-layer filter plate 27 to the bottom. The oil residue and chemical agent water are discharged through the oil drain pipe 8. Motor C33 is turned off, stopping the spiral plate B23's rotation. Motor B321 is started, driving the push plate 22 to return to its original position.

[0026] Open the valve on the slag discharge pipe 7, and connect a pressurized stream of pure water to the outside of the oil discharge pipe 8. This allows the pure water to flow through the multi-layer filter plate 27, carrying out any residual chemicals within the filter plate 27 and discharging them through the liquid outlet pipe 9. Simultaneously, the pure water flows in the opposite direction through the rectifier grid 26, carrying out any residual chemicals within the rectifier grid 26, and then flows in the opposite direction through the annular cavity into the filter cylinder 25. This carries out larger metal fragments, abrasive particles, and suspended impurities within the filter cylinder 25 and discharges them through the slag discharge pipe 7. If there are too many impurities in the filter cylinder 25, causing severe blockage, consider starting the motor A31 to rotate the spiral plate A21 at a lower speed to clean the inside of the filter cylinder 25 and push the backwashed filter residue to the bottom. The backwashing water and filter residue are then discharged through the slag discharge pipe 7.

[0027] This embodiment utilizes a spiral plate to both accelerate the cutting fluid through the filter cartridge for filtration and to clean the filter residue and oil, transporting them to their respective discharge ports, making the backwashing process convenient and quick. This embodiment also employs an annular cavity with an outer filter cartridge, optimizing the shape and significantly reducing the space occupied by such devices.

[0028] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
