Description

Technical Field

[0001] This invention relates to the field of electrophoresis equipment technology, specifically to a mechanical structure for an electrophoresis treatment tank with a constant temperature stirring function. Background Technology

[0002] Electrophoresis is the process by which charged particles move towards an electrode with the opposite charge under the influence of an electric field. Electrophoresis has been increasingly widely applied in various fields such as analytical chemistry, biochemistry, clinical chemistry, toxicology, pharmacology, immunology, microbiology, and food chemistry. With social progress, electrophoresis technology has also been gradually applied to automotive primers and hardware surface treatment, achieving significant economic benefits in the industry. The electrophoresis tank is a very important piece of equipment in electrophoresis technology. Deviations in the parameter control within the electrophoresis tank often lead to unsatisfactory electrophoresis results.

[0003] In existing technologies, defects such as particles, pinholes, and pores in electrophoresis products are mostly caused by a decline in parameters or liquid quality within the electrophoresis tank. After prolonged electrophoresis, the pH value in the electrophoresis tank may exceed the range, leading to defects. Oil stains floating on the liquid surface can also cause pinholes. As the electrophoresis time increases and the temperature changes, impurity ions increase, requiring the continuous addition of pure water, which consumes a huge amount of pure water and increases costs. Summary of the Invention

[0006] Preferably, the baffle includes a plate body, with openings on both sides of the plate body, and a rotating layer is rotatably connected to the inside of the opening via a shaft.

[0007] Preferably, a U-shaped stop frame is provided on the lower side of the rotating layer, and the two ends of the stop frame are fixedly connected to the plate body.

[0008] Preferably, a hollow elastic telescopic rod is provided on one side of the connecting column, and the elastic telescopic rod is fixedly connected to the upper chamber. A slot is provided on the surface of the connecting column corresponding to the elastic telescopic rod.

[0009] Preferably, extension plates are fixed at both ends of the stirring shaft, and magnetic blocks are fixed on the sidewalls of the extension plates.

[0010] Preferably, a heat-conducting plate is fixedly provided on the inner side wall of the electrophoresis tank, and a cooling channel is opened inside the heat-conducting plate. An inlet and an outlet are respectively provided at both ends of the cooling channel. Several temperature sensors are fixedly provided inside the electrophoresis tank.

[0011] Preferably, an oil removal assembly is installed inside the upper chamber. The oil removal assembly includes two sets of sliding plates, which are slidably installed on both sides of the upper chamber. A collection plate is rotatably arranged on the lower axis of the sliding plate, and a collection groove is opened on the surface of the collection plate. Linear lifting devices are respectively arranged on both sides of the electrophoresis tank to adjust the height of the sliding plates. Several flow holes one and flow holes two are respectively opened on the opposite side of the two collection grooves.

[0012] Preferably, the side wall of the collecting plate is provided with a groove, and a drain connector connected to the collecting tank is fixed in the groove, and a valve is installed on the drain connector.

[0013] Preferably, the first flow hole is a convex channel, and a magnetic ring is embedded and fixed inside the first flow hole, and the channel of the first flow hole facing the second flow hole is a frustum shape.

[0014] Preferably, a T-shaped connector is provided inside the second flow hole, and a plurality of support blocks are provided on the outer wall of the connector. A support ring is fixedly provided on the side of the connector facing the first flow hole, and a magnetic ring is embedded in the side wall of the support ring. A tension spring is fixed between the support ring and the collecting plate.

[0015] Working principle: When the driving device drives the stirring shaft to rotate in the opposite direction, the stirring blades remain vertical due to liquid resistance, which can fully stir the electrophoresis solution and prevent it from settling and affecting subsequent use. When electrophoresis is performed, stirring is stopped, and the stirring blades fold under gravity to reduce the space occupied. After electrophoresis for a period of time, impurities will accumulate at the bottom of the tank, and the pH value of the solution will also change. At this time, the driving device drives the stirring shaft to rotate in the forward direction, and the motor shaft drives the push block to rotate. The push block abuts against the protrusion, which drives the winding wheel to rotate. The winding wheel winds up the rope, pulling the baffle upward. The process continues until the baffle touches the top wall of the lower chamber, separating the upper and lower chambers. Then, the drain port is opened to discharge some of the tank liquid and debris deposited at the bottom of the lower chamber. After drainage, the drain port is closed, and the drive unit rotates in the opposite direction. When the push block contacts the protrusion, it rotates and passes over the protrusion, and no further pushing force is applied. The baffle falls under gravity, pulling the take-up wheel to unload the line in the opposite direction, reopening the lower chamber. Finally, pure water is added. The discharge and separation of the liquid in the lower chamber is completed by the raising and lowering of the baffle, achieving the effect of saving pure water.

[0016] This invention provides a mechanical structure for an electrophoresis treatment tank with a constant temperature stirring function. It has the following beneficial effects: 1. This invention, through the cooperation of the stirring shaft and stirring blades, can fully stir the electrophoretic solution when rotating in opposite directions, avoiding the sedimentation problem caused by long-term stillness and ensuring the uniformity of the electrophoretic solution composition; at the same time, the stirring blades can rotate and fold under gravity during electrophoresis, reducing interference with the workpiece electrophoresis process. Combined with the degreasing component, it can accurately collect the grease floating on the surface of the bath solution, avoiding the shrinkage defects caused by grease, reducing product defects such as particles and pinholes from the source, and significantly improving the quality of electrophoretic processing.

[0017] 2. The heat-conducting plate inside the chamber of this invention, together with the cooling channel, forms a high-efficiency temperature control system. Combined with temperature sensors distributed in multiple areas, the temperature of the electrophoresis solution can be monitored in real time. The flow rate of the coolant can be adjusted by the control unit to achieve precise cooling or heat preservation in different areas, ensuring that the electrophoresis solution is always within a suitable temperature range, avoiding the impact of temperature fluctuations on the electrophoresis effect, and ensuring the stability and consistency of the process.

[0018] 3. The present invention utilizes the baffle lifting design of the drain assembly to achieve the separation and connection of the upper and lower chambers. Impurities generated during electrophoresis are deposited in the lower chamber. When the tank solution needs to be adjusted, only the impurity-containing liquid and sediment in the lower chamber need to be drained, without replacing the entire tank solution, which greatly reduces the amount of pure water replenishment and lowers water consumption and production costs.

[0019] 4. The drainage component of this invention realizes the automatic lifting, locking and unlocking of the baffle through the forward and reverse rotation of the stirring shaft, without the need for manual operation of the partition structure; the oil removal component uses a linear lifting device to drive the collection plate to automatically complete the unfolding, oil collection and drainage cleaning. The whole process is highly automated, which not only reduces the intensity of manual labor, but also reduces operation errors, and improves the operating efficiency and maintenance convenience of the equipment.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 4 This invention provides a mechanical structure for an electrophoresis tank with a constant temperature stirring function. The tank includes an electrophoresis tank 1, which comprises an upper chamber 2 and a lower chamber 3. A stirring shaft 4 is rotatably mounted inside the upper chamber 2, and stirring blades 5 are rotatably mounted on the surface of the stirring shaft 4. A drive device (not shown in the figure) is mounted on the surface of the electrophoresis tank 1 to drive the stirring. The drive device is a motor. When the motor is fixed to the top of the electrophoresis tank 1, transmission is achieved by fixing sprockets on the motor shaft and the stirring shaft 4, and then engaging the two sprockets with a chain. When the motor is fixed to the side wall of the electrophoresis tank 1, the motor shaft passes through the electrophoresis tank 1 and the rotating wheel, and is fixedly connected to one end of the stirring shaft 4 for transmission. A torque sensor is mounted on the motor shaft, connected in series between the motor output shaft and the stirring shaft 4, to collect real-time feedback data during rotor rotation. The force torque is directly output as the resistance torque value, which is used to detect the load resistance applied to the motor when the baffle 61 abuts against the lower chamber 3, thereby controlling the motor to shut down in time. The lower side wall of the lower chamber 3 is fixed with a drain port with a valve, and the lower chamber 3 is equipped with a drain assembly 6. The drain assembly 6 includes a baffle 61, and several connecting posts 62 are fixed on the upper surface of the baffle 61. A winding wheel 63 that is rotatably connected to the upper chamber 2 is set above the connecting posts 62. A pull rope 64 is fixed between the winding wheel 63 and the connecting posts 62. A cavity is opened inside the winding wheel 63, and a protrusion 66 is fixed inside the cavity. The two ends of the stirring shaft 4 extend into the cavity and are rotatably connected to push blocks 7. A sealing gasket is fixed at the contact point between the upper surface of the baffle 61 and the inner wall of the lower chamber 3 to improve the sealing performance when the two abut against each other.

[0024] Specifically, the drive device drives the stirring shaft 4 to rotate in the opposite direction, causing the stirring blades 5 to rotate against the stirring shaft 4 under the action of liquid resistance, maintaining a vertical position to stir the electrophoresis solution. This ensures thorough agitation of the electrophoresis solution, preventing sedimentation that would occur during prolonged static conditions and affect subsequent normal use. During electrophoresis, stirring stops, and the blades rotate and fold under gravity, reducing their space occupation. After a period of electrophoresis, impurities will accumulate at the bottom of the tank, and the pH value of the solution will also change, requiring the addition of pure water and the removal of some of the original solution. At this time, the drive device drives the stirring shaft 4 to rotate in the forward direction. Simultaneously, the motor shaft drives the push block 7 to rotate. The push block 7, through contact with the protrusion 66, drives the winding wheel 63 to rotate. At this point, the push block 7 and the stirring... The centerline of the mixing shaft 4 remains vertical, causing the take-up wheel 63 to take up the pull rope 64 and pull the baffle 61 upward until it touches the top wall of the lower chamber 3, thus separating the upper chamber 2 and the lower chamber 3. Then, the drain port is opened to discharge some liquid and the debris deposited at the bottom of the lower chamber 3. Finally, the drain port is closed, and the drive device is controlled to rotate in the forward direction. When the drive device rotates in the reverse direction, the push block 7 rotates when it contacts the protrusion 66 and passes through the protrusion 66. No longer, the push force is applied to the protrusion 66. At this time, under the action of gravity of the baffle 61, the take-up wheel 63 is pulled to rotate in the reverse direction to release the line, thereby opening the lower chamber 3. Then, pure water is added. The discharge and separation of the liquid inside the lower chamber 3 is achieved by the raising and lowering of the baffle 61, thus saving pure water.

[0025] Please see the appendix Figure 5 -Appendix Figure 6 The baffle 61 includes a plate 611, with openings 612 on both sides of the plate 611. A rotating layer 614 is rotatably connected inside the opening 612 via a shaft. A sealing gasket is fixed at the intersection of the rotating layer 614 and the plate 611 to improve the sealing performance when closed.

[0026] Specifically, when the baffle 61 descends into the lower chamber 3, the rotating layer 614 rotates downward under gravity, forming an inverted V-shape, thereby reducing the obstruction of the baffle 61 on the debris, allowing the debris to accumulate at the bottom of the lower chamber 3 for discharge. When the baffle 61 abuts against the inner top wall of the lower chamber 3, the rotating layer 614 is blocked by the inner top wall of the lower chamber 3 and rotates to remain horizontal, thereby closing the opening 612 for isolation.

[0027] Please see the appendix Figure 6 A U-shaped stop frame 615 is provided on the lower side of the rotating layer 614, and the two ends of the stop frame 615 are fixedly connected to the plate 611.

[0028] Specifically, the stop frame 615 is used to restrict the rotation position of the rotating layer 614, so as to prevent one end of the rotating layer 614 from touching the bottom and affecting the impurities to be accumulated relatively evenly in the lower chamber 3.

[0029] Please see the appendix Figure 7A hollow elastic telescopic rod 67 is provided on one side of the connecting column 62. The elastic telescopic rod 67 includes an outer cylinder that is slidably connected and an inner rod made of ferromagnetic material. An elastic element is fixed between the outer cylinder and the inner rod. The elastic telescopic rod 67 is fixedly connected to the upper chamber 2. A slot 68 is provided on the surface of the connecting column 62 corresponding to the elastic telescopic rod 67.

[0030] Specifically, the inner rod is pressed tightly against the connecting post 62 by the elastic force of the elastic element. When the baffle 61 presses against the top wall of the lower chamber 3, the connecting post 62 rises so that the slot 68 is aligned with the elastic telescopic rod 67. At this time, the inner rod of the elastic telescopic rod 67 is inserted into the slot 68, thereby locking the position of the baffle 61 and reducing the load when the motor stops.

[0031] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 7 An extension plate 8 is fixed at both ends of the stirring shaft 4, and a magnetic block 10 is fixed on the side wall of the extension plate 8.

[0032] Specifically, when the drive device rotates in the reverse direction, it first drives the extension plate 8 to rotate to the elastic telescopic rod 67. The extension plate 8 drives the magnetic block 10 to rotate through the elastic telescopic rod 67. Through the magnetic attraction between the magnetic block 10 and the inner rod, the inner rod is disengaged from the slot 68, thereby achieving automatic unlocking and allowing the baffle 61 to fall automatically.

[0033] Please see the appendix Figure 8 A heat-conducting plate 11 is fixedly installed on the inner wall of the electrophoresis tank 1. A cooling channel is opened inside the heat-conducting plate 11, and an inlet and an outlet are respectively provided at both ends of the cooling channel. Several temperature sensors are fixedly installed inside the electrophoresis tank 1. The temperature sensors and the water pump are electrically connected to a control unit. Multiple sets of heat-conducting plates 11 and temperature sensors can be set and respectively set in different areas inside the upper chamber 2 and the lower chamber 3 for zoned temperature detection and temperature adjustment.

[0034] Specifically, the water pump outlet is connected to the water pump inlet, and the water pump inlet and outlet are connected to the cooling pool. The water pump draws coolant and circulates it through the cooling channel, which can absorb the temperature of the electrophoretic solution to achieve a cooling effect.

[0035] Before electrophoresis, the control unit presets the appropriate temperature range for the electrophoresis solution. During the electrophoresis process, temperature sensors collect real-time temperature data of the electrophoresis solution in the tank and transmit the data to the control unit. The control unit analyzes and processes the received temperature data to determine whether the temperature of each region is within the preset threshold range. If the temperature in a certain area is higher than the preset threshold, the control unit controls the water pump to increase the flow rate and the flow of the cooling medium, thereby increasing the cooling intensity of that area and achieving precise cooling. If the temperature is lower than the preset threshold, the control unit can control the flow rate to decrease or shut down, or reduce the flow of the cooling medium for the corresponding independent cooling plate, to ensure that the temperature rises back to the preset range. By controlling the temperature, the electrophoresis quality is improved.

[0036] Please see the appendix Figure 8 -Appendix Figure 9 The upper chamber 2 is equipped with an oil removal assembly 9, which includes two sets of slide plates 901. The two slide plates 901 are slidably installed on both sides of the upper chamber 2. A collection plate 902 is rotatably mounted on the lower shaft of the slide plate 901, and a collection groove is opened on the surface of the collection plate 902. Linear lifting devices 12 are respectively provided on both sides of the electrophoresis tank 1 to adjust the height of the slide plate 901. The linear lifting device 12 can be a linear motor, an electric push cylinder or a pneumatic cylinder. Several flow holes 1 904 and flow holes 2 905 are respectively opened on the opposite side of the two collection grooves.

[0037] Specifically, during electrophoresis, the linear lifting device 12 extends, causing the slide plate 901 to descend to the lowest point. At this time, the collecting plate 902 rotates downward under the influence of gravity, leaving processing space for the workpiece. During operation, grease will be generated on the surface of the tank liquid. When cleaning is required, the linear lifting device 12 drives the slider to rise slowly. At this time, the collecting plate 902 is blocked by the upper inner wall of the upper chamber 2 and rotates to maintain a horizontal position. During this process, the electrophoretic liquid in the collecting tank flows out through the first flow hole 904 and the second flow hole 905, thereby reducing the resistance during the rise. When the collecting tank rises above the liquid surface, the grease floating on the surface of the tank liquid stays in the collecting tank, thereby collecting the oil residue for processing.

[0038] Please see the appendix Figure 8 The side wall of the collecting plate 902 is provided with a groove, and a drain connector 903 connected to the collecting tank is fixed in the groove, and a valve is installed on the drain connector 903.

[0039] Specifically, after the collection plate 902 rises, the drain connector 903 is connected to the sewage pipe and the valve is opened, so that the oil and some of the electrophoretic liquid in the collection tank are discharged through the drain connector 903. Then, the collection tank is manually rinsed with degreasing liquid to clean and collect the grease.

[0040] Please see the appendix Figure 8 -Appendix Figure 9The first flow hole 904 is a convex channel, and a magnetic ring 911 and a sealing ring are embedded and fixed at the end of the first flow hole 904 facing the second flow hole 905. The channel of the first flow hole 904 facing the second flow hole 905 is frustoconical so that the support ring 908 can exit the first flow hole 904 when the collecting plate 902 rotates downward. The second flow hole 905 is provided with a T-shaped connector 907. A sealing ring is fixed on the side of the connector 907 facing the inner side wall of the collecting tank. The sealing performance is improved by the two sets of sealing rings pressing and cooperating with the support ring 908 and the connector 907 under the magnetic attraction. Several support blocks are provided on the outer wall of the connector 907. A support ring 908 is fixed on the side of the connector 907 facing the first flow hole 904, and a magnetic ring 909 is embedded in the side wall of the support ring 908. A tension spring 910 is fixed between the support ring 908 and the collecting plate 902.

[0041] Specifically, the connector 907 is supported by the support block, so that the connector 907 and the second flow hole 905 are concentrically distributed. The tension ring 910 applies tension to the support ring 908, making it close to the second flow hole 905. When the two collecting plates 902 rotate horizontally, the first flow hole 904 and the second flow hole 905 are horizontally aligned. At this time, the magnetic attraction force between the magnetic ring 909 and the magnetic attraction ring 911 makes the support ring 908 insert into the first flow hole 904, thereby connecting the two collecting plates 902 and improving the stability of the rising collecting plates 902. At the same time, the support ring 908 and the connector 907 cooperate to block the first flow hole 904 and the second flow hole 905 respectively to prevent grease from flowing out. When the collecting plate 902 rotates downward, it should be understood that when the collecting plate 902 rotates horizontally, the bottom wall of the collecting tank is lower than the liquid surface and the top is higher than the liquid surface.

[0042] Workflow: After electrophoresis has been performed for a period of time, impurities will accumulate at the bottom of the tank. In addition, the pH value of the tank solution will change. It is necessary to add pure water and drain some of the original tank solution. At this time, the drive equipment drives the stirring shaft 4 to rotate in the forward direction. The motor shaft drives the push block 7 to rotate. The push block 7 drives the winding wheel 63 to rotate by contacting the protrusion 66. At this time, the push block 7 is perpendicular to the center line of the stirring shaft 4, so that the winding wheel 63 winds up the pull rope 64 and pulls the baffle 61 up until it hits the top wall of the lower chamber 3, thereby separating the upper chamber 2 and the lower chamber 3. Then, open the drain port to discharge some liquid and debris deposited at the bottom of the lower chamber 3. Finally, close the drain port and control the drive device to rotate forward. When the drive device rotates in the reverse direction, the push block 7 rotates when it contacts the protrusion 66 and passes through the protrusion 66. No longer push force is applied to the protrusion 66. At this time, under the gravity of the baffle 61, the winding wheel 63 is pulled to rotate in the reverse direction to release the line, thereby opening the lower chamber 3. Then, pure water can be added. The discharge and separation of the liquid inside the lower chamber 3 is achieved by raising and lowering the baffle 61, thus saving pure water.

[0043] During electrophoresis, the linear lifting device 12 extends, causing the slide plate 901 to descend to the lowest point. At this time, the collecting plate 902 rotates downward under the influence of gravity, leaving processing space for the workpiece. During operation, grease will be generated on the surface of the tank liquid. When cleaning is required, the linear lifting device 12 drives the slider to rise slowly. At this time, the collecting plate 902 is blocked by the upper inner wall of the upper chamber 2 and rotates to maintain a horizontal position. During this process, the electrophoretic liquid in the collecting tank flows out through the first flow hole 904 and the second flow hole 905, thereby reducing the resistance during the rise. When the collecting tank rises above the liquid surface, the grease floating on the surface of the tank liquid stays in the collecting tank, thereby collecting the oil residue for processing.
