Description

Technical Field

[0001] This invention relates to the field of filtration, specifically to an electrophoretic treatment mechanical device with automatic circulating filtration function. Background Technology

[0002] Electrophoretic coating machines are automated industrial equipment that uses electrophoresis technology to coat or treat the surface of materials. The principle involves immersing conductive workpieces in a bath containing water-soluble electrophoretic coatings. An external DC electric field causes charged resin and pigment particles in the coating to migrate and deposit directionally on the workpiece surface, forming a uniform, dense, and strongly adhesive coating. This process is the cornerstone of modern coating industry, widely used for anti-corrosion primers and decorations in automotive bodies, chassis, hardware, home appliances, and building materials. Its outstanding advantages include a seamless coating, excellent edge coverage, and uniform and controllable film thickness. It also boasts high environmental friendliness and economy, with extremely low volatile organic compound emissions, and is easily automated for production lines. A complete electrophoretic coating machine typically consists of a main electrophoresis tank, a dedicated rectifier power supply system, a precise temperature and pH control system, a circulating filtration device to maintain bath stability, and a crucial post-coating ultrafiltration cleaning unit. Electrophoretic coating machines provide a vital foundation for the long-term durability and appearance quality of industrial products.

[0003] During the operation of the electrophoresis treatment machine, the electrophoresis solution needs to be filtered to remove impurity particles, including iron filings and phosphate slag that fall off the workpiece. If these impurities are not removed, they will directly damage the coating quality. They will adhere to the surface of the wet paint film and form particle protrusions after curing, affecting the appearance and feel. In the existing technology, when filtering the electrophoresis solution, it usually relies on the gravity of the electrophoresis solution to flow to the filtration equipment. This method has low filtration efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an electrophoresis treatment mechanical device with an automatic circulating filtration function, which solves the problem of low working efficiency caused by relying on the gravity flow of the electrophoretic liquid to the filtration equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electrophoretic treatment mechanical device with automatic circulating filtration function, comprising a funnel, the lower end of which is inverted conical, a filter cylinder inside the funnel, a cleaning component on the side wall of the filter cylinder, a rotating rod at the bottom of the filter cylinder, a first bevel gear at the upper end of the rotating rod, a second bevel gear on one side of the first bevel gear, the second bevel gear meshing with the first bevel gear, a drive shaft at the middle of the second bevel gear, a first pulley at one end of the drive shaft, a second pulley below the first pulley, the first pulley and the second pulley connected by a belt, a shaft at the middle of the second pulley, a rotating plate at one end of the shaft, a drive mechanism and a striking mechanism at the other end of the shaft, a hollow column at the bottom of the funnel, the rotating plate rotating inside the hollow column, a filter box at the bottom of the hollow column, an outlet at the bottom of the filter box, and a secondary filtration component inside the filter box.

[0006] The above technical solution achieves the following: by starting the drive motor, the filter cylinder, the striking mechanism, and the drive mechanism are driven simultaneously, enabling one power source to drive multiple devices. The filter cylinder, driven by the drive motor, undergoes centrifugal motion. Under centrifugal force, impurities are rapidly pushed against the cylinder wall and trapped by the filter cylinder, significantly improving the filtration effect. The drive mechanism drives the filter plate in reciprocating motion, accelerating the movement of the electrophoretic liquid and enhancing the filtration effect. Furthermore, the striking mechanism, while the filter plate is filtering the electrophoretic liquid, drives a ball to rhythmically strike the filter plate, dislodging impurities clogging the filter pores, restoring and maintaining the filter plate's patency, thus achieving continuous and efficient filtration.

[0007] Preferably, the cleaning assembly includes a connecting cylinder installed on the side wall of the filter cylinder, a connecting rod inside the connecting cylinder, a spring inside the connecting cylinder, one end of the spring being connected to the side wall of the filter cylinder, the other end of the spring being connected to the end of the connecting rod, a scraper being installed on the other end of the connecting rod, the end of the scraper being tapered, and one end of the scraper being tightly fitted against the inner wall of the funnel, a through hole being opened in the side wall of the connecting cylinder, and a limiting post being provided on the side wall of the connecting rod that is adapted to the through hole, the limiting post being locked in the through hole, and the limiting post being used to restrict the rotation of the connecting rod.

[0008] Preferably, the secondary filtration assembly includes a filter frame installed inside a filter box, with both ends of the filter frame passing through the side wall of the filter box. The filter frame has an installation groove, in which a filter plate is installed. The surface of the filter frame is inclined.

[0009] Preferably, the driving mechanism includes a third bevel gear mounted on the end of a shaft, a fourth bevel gear located below the third bevel gear, the third and fourth bevel gears meshing with each other, a rotating shaft mounted on the fourth bevel gear, a turntable mounted at the bottom of the rotating shaft, a drive shaft mounted at the bottom of the turntable, a sliding groove connecting rod sleeved on the drive shaft, the drive shaft driving the sliding groove connecting rod to reciprocate in the horizontal direction, a pull rod mounted on the side wall of the sliding groove connecting rod, the other end of the pull rod being connected to a filter frame, a fixing ring sleeved on the pull rod, the fixing ring being used to control the reciprocating motion of the pull rod, and the curvature of the drive shaft surface matching the curvature of both ends of the sliding groove connecting rod.

[0010] Preferably, the striking mechanism includes a first gear mounted on a shaft, the first gear being located between a second pulley and a third bevel gear, a second gear meshing below the first gear, a striking rod mounted on the second gear, the striking rod being L-shaped, and a ball at the end of the striking rod, the ball performing circular motion, and when the ball rotates to its highest point, a gap is left between the ball and the top of the filter box.

[0011] Preferably, a rubber strip is installed in the middle of the filter box, and the filter frame is tightly fitted with the rubber strip. The rubber strip is used to seal the filter box. A bracket is fixedly installed on the side wall of the filter box, and a protective shell is installed on the bracket. The first gear, the second gear, the third bevel gear, and the fourth bevel gear are located inside the protective shell.

[0012] Preferably, a drive motor is provided on one side above the funnel, the output end of the drive motor is connected to the end of the transmission shaft, a circulation pump is installed on the side wall of the funnel, the output end of the circulation pump is connected to a pipe, and the other end of the pipe passes through the top of the funnel and is placed inside the filter cylinder.

[0013] Preferably, the top of the funnel is provided with an annular groove, and the filter cylinder rotates within the annular groove.

[0014] Preferably, the filter cartridge is used for coarse filtration of the electrophoresis solution, and the secondary filtration assembly is used for fine filtration of the electrophoresis solution.

[0015] Preferably, the circulating pump pumps the electrophoresis solution into the filter cartridge through the pipeline. The electrophoresis solution is filtered by the filter cartridge and flows downward into the filter box. It is then filtered again by the filter plate and finally flows out from the outlet.

[0016] Working principle: During operation, the circulation pump and drive motor are started. The circulation pump pumps the electrophoresis solution into the filter cartridge through the pipeline. The output end of the drive motor drives the transmission shaft to rotate, which in turn drives the second bevel gear to rotate, and in turn drives the first bevel gear meshing with it to rotate, thereby driving the rotating rod and the filter cartridge to rotate. The rotating filter cartridge causes the electrophoresis solution to undergo centrifugal motion. As the filter cartridge rotates, it drives the scraper connected to it to rotate, which in turn scrapes the electrophoresis solution on the inner wall of the funnel. The electrophoresis solution flows into the filter box through the hollow column. The drive motor drives the first pulley to rotate, which in turn drives the second pulley connected by the belt to rotate. The rotating shaft drives the shaft and rotating plate to rotate. As the electrophoretic solution passes through the hollow column, the rotating plate agitates the electrolyte. The rotation of the shaft also drives the first gear to rotate, which in turn drives the second gear and the striking rod to rotate. The rotating rod, in turn, drives the ball to make a circular motion, periodically striking the filter plate. The rotation of the shaft also drives the third bevel gear to rotate, which in turn drives the fourth gear meshing with it to rotate, thereby driving the turntable to rotate. The rotation of the turntable drives the drive shaft to make a circular motion, which in turn drives the sliding groove connecting rod and the pull rod to make a reciprocating motion, thereby driving the filter plate to make a reciprocating motion.

[0017] This invention provides an electrophoresis treatment mechanical device with automatic circulating filtration function. It has the following beneficial effects: 1. The present invention uses a filter cylinder that is driven to rotate during operation. When the electrophoresis liquid is pumped into the filter cylinder by the circulation pump, the rotating filter cylinder causes the electrophoresis liquid to undergo centrifugal motion. Under the action of centrifugal force, impurities are quickly pushed to the cylinder wall and intercepted by the filter cylinder, which significantly improves the filtration effect.

[0018] 2. The present invention uses a secondary filtration component to filter the electrophoresis solution again. While the filter plate is filtering, the drive mechanism drives the filter frame and the filter plate to reciprocate, which accelerates the movement of the electrophoresis solution and improves the filtration effect.

[0019] 3. The present invention uses a tapping mechanism to drive a ball to regularly tap the filter plate when the filter plate is filtering the electrophoresis liquid, thereby shaking off the impurities blocking the filter holes, restoring and maintaining the unobstructed flow of the filter plate, so as to achieve continuous and efficient filtration.

[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] Example: Refer to Figure 1 and Figure 2 as well as Figure 3This invention provides an electrophoresis treatment device with automatic circulating filtration function, including a funnel 1, the lower end of which is inverted conical. A filter cylinder 2 is disposed inside the funnel 1, and a cleaning assembly 3 is provided on the side wall of the filter cylinder 2. A rotating rod 21 is installed at the bottom of the filter cylinder 2, and a first bevel gear 4 is installed at the upper end of the rotating rod 21. A second bevel gear 5 is provided on one side of the first bevel gear 4, and the second bevel gear 5 meshes with the first bevel gear 4. A drive shaft 6 is installed in the middle of the second bevel gear 5, and a first bevel gear 6 is installed at one end of the drive shaft 6. A first pulley 7 is provided, and a second pulley 8 is provided below the first pulley 7. The first pulley 7 and the second pulley 8 are connected by a belt. A shaft 9 is installed in the middle of the second pulley 8. A rotating plate 10 is installed at one end of the shaft 9. A drive mechanism 11 and a striking mechanism 12 are provided at the other end of the shaft 9. A hollow column 13 is installed at the bottom of the funnel 1. The rotating plate 10 rotates inside the hollow column 13. A filter box 14 is installed at the bottom of the hollow column 13. A water outlet is provided at the bottom of the filter box 14. A secondary filtration assembly 15 is provided inside the filter box 14.

[0024] Specifically, in practical applications, the drive motor 17 drives the filter cylinder 2 to rotate. At the same time, the electrophoretic liquid is pressurized by the circulation pump 20 and continuously pumped into the rotating filter cylinder 2. The electrophoretic liquid inside the cylinder undergoes centrifugal motion as the filter cylinder 2 rotates. During this process, the centrifugal force experienced by solid suspended impurities with a density greater than that of liquid far exceeds gravity, and they are quickly thrown towards the inner wall of the cylinder. The impurities are trapped on the inner wall of the filter cylinder 2, while the pure electrophoretic liquid passes through the filter cylinder 2 under the drive of centrifugal motion, significantly improving the filtration effect. The electrophoretic liquid thrown out by the filter cylinder 2 flows into the filter box 14 through the hollow column 13 for secondary filtration. This filtration is fine filtration. When the electrophoretic liquid flows through the hollow column 13, the rotating plate 10 rotates inside the hollow column 13, so that the electrophoretic liquid flows more smoothly into the filter box 14 under the action of stirring for the second filtration.

[0025] Reference Figure 7 The cleaning component 3 includes a connecting cylinder 301 installed on the side wall of the filter cylinder 2. A connecting rod 302 is provided inside the connecting cylinder 301. A spring 303 is provided inside the connecting cylinder 301. One end of the spring 303 is connected to the side wall of the filter cylinder 2, and the other end of the spring 303 is connected to the end of the connecting rod 302. A scraper 304 is installed on the other end of the connecting rod 302. The end of the scraper 304 is tapered. One end of the scraper 304 is tightly fitted to the inner wall of the funnel 1. A through hole is opened on the side wall of the connecting cylinder 301. A limiting post 305 that is adapted to the through hole is provided on the side wall of the connecting rod 302. The limiting post 305 is stuck in the through hole and is used to limit the rotation of the connecting rod 302.

[0026] Specifically, when the filter cylinder 2 drives the electrophoresis liquid to perform centrifugal motion, the filtered electrophoresis liquid is thrown out. Some of the electrophoresis liquid is thrown out and flows directly to the bottom of the funnel 1, while some of the electrophoresis liquid is thrown onto the inner wall of the funnel 1. The scraper 304 is set to rotate while the filter cylinder 2 rotates, thereby scraping off the electrophoresis liquid on the inner wall of the funnel 1. The spring 303 is set to apply a pushing force to the scraper 304 while it is rotating, so that the scraper 304 moves closely against the inner wall of the funnel 1, making the scraping cleaner.

[0027] Reference Figure 5 and Figure 6 as well as Figure 8 The secondary filtration assembly 15 includes a filter frame 1501 installed in the filter box 14. Both ends of the filter frame 1501 pass through the side wall of the filter box 14. An installation groove is provided on the filter frame 1501, and a filter plate 1502 is installed in the installation groove. The surface of the filter frame 1501 is inclined.

[0028] Specifically, after centrifugation filtration, the electrophoresis liquid flows into the filter box 14, which is equipped with a filter plate 1502 to finely filter the incoming liquid, removing finer suspended impurities and thus further improving the cleanliness of the electrophoresis liquid.

[0029] Reference Figure 3 and Figure 4 as well as Figure 6 The drive mechanism 11 includes a third bevel gear 1101 installed at the end of the shaft 9, a fourth bevel gear 1102 located below the third bevel gear 1101, the third bevel gear 1101 and the fourth bevel gear 1102 meshing with each other, a rotating shaft 1103 installed on the fourth bevel gear 1102, a turntable 1104 installed at the bottom of the rotating shaft 1103, a drive shaft 1105 installed at the bottom of the turntable 1104, a sliding groove connecting rod 1106 sleeved on the drive shaft 1105, the drive shaft 1105 drives the sliding groove connecting rod 1106 to reciprocate in the horizontal direction, a pull rod 1107 installed on the side wall of the sliding groove connecting rod 1106, the other end of the pull rod 1107 connected to the filter frame 1501, a fixing ring 1108 sleeved on the pull rod 1107, the fixing ring 1108 used to control the reciprocating motion of the pull rod 1107, the curvature of the drive shaft 1105 and the curvature of the two ends of the sliding groove connecting rod 1106 are adapted to each other.

[0030] Specifically, when the electrophoretic solution flows through the filter plate 1502, the drive mechanism 11 will simultaneously drive the filter frame 1501 and the filter plate 1502 to perform high-frequency, small-amplitude reciprocating motion. This causes the electrophoretic solution to move with the filter plate 1502, generating turbulence and acceleration effects. The reciprocating motion also produces periodic vibration and loosening effects on the already trapped impurity layer, effectively slowing down the rate at which the filter pores become clogged. The curvature of the drive shaft 1105 and the curvature of both ends of the sliding connecting rod 1106 are matched, allowing the drive shaft 1105 to drive the sliding connecting rod 1106 to perform reciprocating motion more smoothly, ensuring smooth operation.

[0031] Reference Figure 5 The striking mechanism 12 includes a first gear 1201 mounted on a shaft 9. The first gear 1201 is located between the second pulley 8 and the third bevel gear 1101. A second gear 1202 is meshed below the first gear 1201. A striking rod 1203 is mounted on the second gear 1202. The striking rod 1203 is L-shaped and has a ball 1204 at its end. The ball 1204 makes a circular motion. When the ball 1204 rotates to its highest point, there is a gap between the ball 1204 and the top of the filter box 14.

[0032] Specifically, through the set tapping mechanism 12, when the filter plate 1502 filters the electrophoresis liquid, the driven ball 1204 periodically taps the filter plate 1502, thereby shaking out the impurities blocked in the filter holes, restoring and maintaining the unobstructed flow of the filter plate 1502, so as to achieve continuous and efficient filtration; and while the filter plate 1502 is being tapped, the drive mechanism 11 simultaneously drives the filter plate 1502 to reciprocate. With the cooperation of these two mechanical movements, the impurities blocked deep in the filter holes can be more effectively loosened and shaken out.

[0033] Reference Figure 9 and Figure 10 A rubber strip 16 is installed in the middle of the filter box 14. The filter frame 1501 is tightly fitted with the rubber strip 16. The rubber strip 16 is used to seal the filter box 14. A bracket 18 is fixedly installed on the side wall of the filter box 14. A protective shell 19 is installed on the bracket 18. The first gear 1201, the second gear 1202, the third bevel gear 1101 and the fourth bevel gear 1102 are located inside the protective shell 19.

[0034] Specifically, when the filter frame 1501 reciprocates within the filter box 14, the rubber strip 16 effectively prevents the electrophoresis solution from flowing out of the filter box 14.

[0035] Reference Figure 1 and Figure 2 as well as Figure 11A drive motor 17 is provided on one side above the funnel 1. The output end of the drive motor 17 is connected to the end of the transmission shaft 6. A circulation pump 20 is installed on the side wall of the funnel 1. The output end of the circulation pump 20 is connected to a pipe. The other end of the pipe passes through the top of the funnel 1 and is placed inside the filter cylinder 2. An annular groove is provided on the top of the funnel 1. The filter cylinder 2 rotates in the annular groove.

[0036] Specifically, the top of the filter cylinder 2 is installed in the annular groove, which seals the upper end of the filter cylinder 2 and prevents the electrophoresis liquid from flowing out between the filter cylinder 2 and the top of the funnel 1.

[0037] Reference Figure 2 and Figure 10 The filter cartridge 2 is used for coarse filtration of the electrophoresis solution, and the secondary filter assembly 15 is used for fine filtration of the electrophoresis solution. The circulating pump 20 pumps the electrophoresis solution into the filter cartridge 2 through the pipeline. After being filtered by the filter cartridge 2, the electrophoresis solution flows downward into the filter box 14, is filtered again by the filter plate 1502, and finally flows out from the outlet.

[0038] Specifically, by setting up a secondary filtration component 15, the electrophoresis solution after being treated by the filter cartridge 2 is finely filtered to remove residual fine impurities, thereby significantly improving the final purity of the electrophoresis solution.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
