Description

Technical Field

[0001] This invention relates to the field of blending can production, specifically to a surface corrosion resistance testing device for blending can production. Background Technology

[0002] A mixing tank is an industrial device used for mixing, blending, heating, and storing materials. It uses mechanical stirring, pump circulation, or pneumatic pulse to uniformly mix materials of different components. It is suitable for processing liquids, semi-fluids, and high-viscosity materials and is widely used in the food, pharmaceutical, chemical, lubricant, and coating industries.

[0003] Surface corrosion resistance testing is a quality control step in the production of blending tanks. It is a crucial step in ensuring the long-term stable operation of equipment and guaranteeing product quality and safety. Corrosion weakens the structural strength of the tank, leading to weld cracking, perforation, or leakage. Regular testing can detect corrosion tendencies in advance, avoiding sudden equipment failures and production downtime losses. To facilitate handling in different corrosive environments, existing testing devices are equipped with multiple testing chambers, allowing blending tanks to enter the chambers sequentially for corrosion resistance testing. While this improves the testing efficiency, after the blending tank is tested in the first chamber, a large amount of corrosive liquid residue remains on its surface. If not cleaned, this residue will enter the next testing chamber. As the blending tank enters multiple testing chambers sequentially, it can easily cause contamination of the testing chambers, lacking a proper cleaning function for the blending tank.

A cavity for the prismatic tube to slide within the fixed tube is provided inside the fixed tube. The bottom end of the driven rod is rotatably installed on the top of the positioning frame. A gear located below the positioning frame is fixedly installed outside the driven rod. An mounting ring is fixedly installed between the tops of the multiple scrapers, and multiple racks distributed centrally symmetrically are fixedly installed outside the mounting ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention, through a testing mechanism, enables the installation and positioning of multiple mixing tanks. The mixing tanks are then immersed in a corrosive liquid in a testing tank while rotating. The corrosion resistance of the mixing tanks is determined by the corrosive liquid. After testing, the mixing tanks are transferred to an adjacent cleaning tank to rinse away any remaining corrosive liquid from their surfaces. This facilitates the transfer of the mixing tanks to the next testing tank for continuous testing, preventing contamination of the testing tanks and improving the convenience of continuous testing of the mixing tanks.

[0018] This invention, through a sewage discharge mechanism, enables the cleaning tank to press the ring frame downwards when the mixing tank enters the cleaning tank. The ring frame drives the sleeve to move along the outside of the sleeve, and the spiral slide and the spiral groove on the outside of the sleeve drive the sleeve to rotate. This causes the scraper at the bottom of the sleeve to move in a circular motion along the bottom inner wall of the cleaning tank, quickly pushing the residual sewage on the bottom inner wall of the cleaning tank into the drain hole, thereby improving sewage discharge efficiency and preventing corrosive liquid residue from accumulating at the bottom of the cleaning tank.

[0019] The present invention, through a cleaning mechanism, enables the roller brush to reciprocate and move up and down while the second nozzle cleans the outside of the mixing tank, which facilitates the rapid removal of impurities from the surface of the mixing tank, thereby improving the cleaning efficiency of the mixing tank and making it easier for the mixing tank to enter the next testing tank for testing.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0030] Example 1: Please refer to Figures 1-8 The diagram illustrates a surface corrosion resistance testing device for blending tank production. It includes a base 1 and multiple mounting frames 2 centrally symmetrically fixed to the top of the base 1. Testing tanks 3 are fixedly mounted on the top of the mounting frames 2, each storing different types of corrosive liquids. Blending tanks to be tested are placed into these testing tanks for corrosion resistance testing, facilitating testing in various corrosive environments. Multiple centrally symmetrical water tanks 4 are fixedly mounted on the top of the base 1, and cleaning tanks 5 are fixedly mounted on the top of each water tank 4. The cleaning tanks 5 and testing tanks 3 are staggered, allowing the tested blending tanks to be cleaned by the cleaning tanks 5, facilitating their entry into the next testing tank 3 and preventing cross-contamination. The device also includes a testing mechanism for continuous testing and cleaning of the blending tanks, mounted on the top of the base 1.

[0031] The testing mechanism includes a mounting plate 6 positioned above the device base 1, capable of transporting multiple mixing tanks. The mechanism also includes a first motor 9 fixedly mounted on the top of the device base 1, with its output end fixedly connected to the bottom of the mounting plate 6. Multiple centrally symmetrically distributed electric slides 10 are fixedly mounted on the bottom of the mounting plate 6. The first motor 9 drives the mounting plate 6 to rotate, enabling the replacement of the positions of the multiple electric slides 10. A second motor 11 is fixedly mounted on the slide of each electric slide 10, allowing the electric slide 10 to drive the second motor 11 to move vertically. The output end of the second motor 11 is fixedly mounted on... Equipped with an electric suction cup 12, the bottom of the mixing tank is suctioned by the electric suction cup 12, causing the mixing tank to be inverted under the bottom of the electric suction cup 12. The electric slide table 10 inserts the mixing tank into the test tank 3, immersing the mixing tank in the corrosive liquid of the test tank 3 to test the corrosion resistance of the mixing tank. In conjunction with the first motor 9 and the mounting plate 6, the mixing tank can enter the adjacent cleaning tank 5 for cleaning, and then enter the next test tank 3 for secondary testing. Thus, continuous testing of the mixing tank is achieved. An installation pipe 13 is fixedly installed on the inner wall of the top of the water tank 4. The top end of the installation pipe 13 extends into the interior of the cleaning tank 5 and is fixed. A first nozzle 14 is installed, and the mixing tank inside the cleaning tank 5 can be fitted over the outside of the first nozzle 14. A water pump 15 is fixedly installed at the bottom of the mounting pipe 13. The water pump 15 draws water from the water storage tank 4 and discharges it through the first nozzle 14, allowing the first nozzle 14 to rinse the inner wall of the rotating mixing tank. A second nozzle 16 is fixedly installed inside the cleaning tank 5. The second nozzle 16 is connected to the mounting pipe 13 through a drain pipe, allowing the mounting pipe 13 to inject water into the second nozzle 16 through the drain pipe. The second nozzle 16 can then rinse the outer wall of the rotating mixing tank. The bottom of the cleaning tank 5 is connected to the water storage tank 4. The top of each tank has a corresponding drain hole, allowing the wastewater from rinsing the cleaning tank 5 to enter the water storage tank 4 through the drain hole. A detection probe 40 is fixedly installed on the outside of the electric slide table 10, enabling the detection probe 40 to visually inspect the surface of the mixing tank. A ring filter screen 41 is fixedly installed on the outside of the water pump 15, allowing the water pump 15 to filter impurities in the wastewater when pumping wastewater from the water storage tank 4. The bottom inner wall of the cleaning tank 5 has a frustum structure, which facilitates the discharge of wastewater into the drain hole of the cleaning tank 5. A drain pipe 34 is fixedly installed on the outside of the water storage tank 4, through which the wastewater in the water storage tank 4 can be discharged.

[0032] Example 2: Please refer to Figures 2-6This embodiment further illustrates Example 1. The sewage discharge mechanism shown in the figure includes multiple scrapers 7 arranged symmetrically on the inner wall of the top of the cleaning tank 5. The scrapers 7 can scrape away sewage from the inner wall of the bottom of the cleaning tank 5. The sewage discharge mechanism also includes a positioning plate 17 fixedly installed at the bottom of the first nozzle 14. A positioning frame 18 is fixedly installed on the inner side of the cleaning tank 5. Multiple sliding rods 19 are fixedly installed between the positioning frame 18 and the positioning plate 17, and an annular frame 20 is slidably installed between the multiple sliding rods 19. When the mixing tank enters the cleaning tank 5, the mixing tank can contact the annular frame 20, causing the mixing tank to push the annular frame 20 downward. A spring 21 is fixedly installed between the bottom of the annular frame 20 and the top of the positioning frame 18, so that when the annular frame 20 moves downward, it can activate the spring 21. 1. Compression facilitates the resetting of the ring frame 20. A collar 22 is fixedly installed on the inner side of the ring frame 20, and a sleeve 23 is rotatably installed on the outer side of the mounting tube 13. The collar 22 is slidably installed on the outer side of the sleeve 23. Two spiral slide bars 42 are fixedly installed on the inner side of the collar 22 in a centrally symmetrical distribution. The outer side of the sleeve 23 is provided with a spiral groove for the spiral slide bars 42 to limit their sliding. When the ring frame 20 moves the collar 22 downward, the collar 22 can drive the spiral slide bars 42 to move along the spiral groove on the sleeve 23, causing the spiral slide bars 42 to drive the sleeve 23 to rotate. The scraper 7 is fixedly installed at the bottom of the sleeve 23. When the sleeve 23 rotates, it can drive the scraper 7 to make a circular motion along the bottom inner wall of the cleaning tank 5, discharging the residual sewage in the cleaning tank 5 into the drain hole in the cleaning tank 5.

[0033] Example 3: Please refer to Figures 4-8This embodiment further illustrates other embodiments. The cleaning mechanism shown in the figure includes multiple centrally symmetrically distributed roller brushes 8. The roller brushes 8 are made of bristle material and can clean liquid residue on the surface of the mixing tank. The cleaning mechanism also includes a fixed tube 24 fixedly installed inside the roller brushes 8. A driven rod 25 is slidably installed inside the fixed tube 24, and a prismatic tube 26 is fixedly installed outside the driven rod 25. The fixed tube 24 has a cavity inside for the prismatic tube 26 to slide and limit its movement. When the driven rod 25 rotates, it can drive the fixed tube 24 to rotate through the prismatic tube 26. The fixed tube 24 drives the roller brushes 8 to rotate, so that the roller brushes 8 can rotate and clean the mixing tank. The bottom end of the driven rod 25 is rotatably installed on the top of the positioning frame 18, and the outer side of the driven rod 25... A gear 27 is fixedly installed below the positioning frame 18. An mounting ring 28 is fixedly installed between the tops of multiple scrapers 7, and multiple centrally symmetrically distributed racks 29 are fixedly installed on the outer side of the mounting ring 28. This allows the scrapers 7 to drive the mounting ring 28 to rotate, and the mounting ring 28 drives the gear 27 to rotate via the racks 29, thus rotating the roller brush 8. A coil spring 30 is fixedly installed between the outer side of the driven rod 25 and the inner side of the positioning frame 18. When the driven rod 25 rotates, the coil spring 30 is compressed, and when the racks 29 move away from the gear 27, the spring force of the coil spring 30 causes the driven rod 25 to rotate back. This facilitates the roller brush 8 to reciprocate cleaning of impurities on the surface of the mixing tank, improving cleaning efficiency. Multiple centrally symmetrically distributed racks 29 are fixedly installed on the top of the fixed tube 24. A support plate 32 is fixedly installed on the top of the sliding ball 31 of the cloth driven rod 25. The support plate 32 is fixedly installed on the inner side of the cleaning tank 5, so that the support plate 32 provides support for the top of the driven rod 25. The bottom of the support plate 32 has a spherical groove for the sliding ball 31 to be inserted into, and the spherical groove is a one-third spherical structure. A tension spring 33 is fixedly installed between the bottom of the prismatic tube 26 and the inner side of the fixed tube 24. When the fixed tube 24 rotates, it can drive the sliding ball 31 to slide out of the spherical groove on the support plate 32. The reaction force of the sliding ball 31 pushes the fixed tube 24 to move along the outer side of the prismatic tube 26 and stretches the tension spring 33. As the fixed tube 24 rotates, when the sliding ball 31 is aligned with the spherical groove again, the rebound force of the tension spring 33 makes the fixed tube 24 move along the outer side of the prismatic tube 26. When tube 24 returns to its original position, the sliding ball 31 can enter the spherical groove, enabling the fixed tube 24 to move back and forth, facilitating the rapid removal of impurities from the surface of the cleaning tank 5. Turntables 35 are fixedly installed at both the top and bottom of the driven rod 25. A pull rod 36 is hinged to the outer side of the turntable 35, and a moving rod 37 is rotatably installed between the two pull rods 36. Sliding grooves are provided on the outer sides of the positioning frame 18 and the support plate 32 for the moving rod 37 to slide and be limited. Rotating the turntable 35 allows the pull rod 36 to pull the moving rod 37 back and forth along the inner side of the positioning frame 18 and the support plate 32. A pressing plate 38 is fixedly installed on the outer side of the moving rod 37, causing the moving rod 37 to drive the pressing plate 38 to reciprocate and press the outer side of the roller brush 8, facilitating the squeezing out of any residual water inside the roller brush 8.A U-shaped frame 39 is fixedly installed between the support plate 32 and the positioning frame 18, and the squeezing plate 38 is slidably installed on the inner side of the U-shaped frame 39, allowing the squeezing plate 38 to move along the inner side of the U-shaped frame 39, facilitating the removal of residual sewage from the squeezing plate 38.

[0034] Working principle: First, the operator installs multiple mixing containers to be tested onto multiple electric suction cups 12, and pours various types of corrosive liquids into multiple testing containers 3. Then, water is poured into a cleaning tank 5, allowing the water to flow into the water tank 4 through the drain holes of the cleaning tank 5 and the water storage tank 4. Next, the operator operates multiple electric slides 10, causing the second motor 11 to move downwards. The second motor 11 rotates the electric suction cups 12, inserting the mixing container into the testing container 3 directly below, immersing the rotating container in the corrosive liquid. Then, the electric slides 10 remove the mixing container from the current testing container 3. The rotating container is then visually inspected by a detection probe 40, and the surface condition of the container is recorded. In the event of corrosion, the first motor 9 drives the mounting plate 6 to rotate, which in turn drives multiple electric sliding tables 10 to rotate synchronously, moving the mixing tank above the cleaning tank 5 and inserting it into the cleaning tank 5. The water pump 15 in the water tank 4 draws water from the tank and sends it into the first nozzle 14 and the second nozzle 16. As the mixing tank rotates, the first nozzle 14 and the second nozzle 16 respectively rinse the inner and outer sides of the mixing tank. Simultaneously, the outer side of the mixing tank contacts the outer side of multiple roller brushes 8, and the bottom of the mixing tank contacts the top of the annular frame 20. The annular frame 20 moves downwards along the outer side of the sliding rod 19, compressing the spring 21. The annular frame 20 also drives the collar 22 along the outer side of the sleeve 23. Moving downwards, the collar 22 drives the spiral slide 42 to move along the spiral groove on the sleeve 23, causing the spiral slide 42 to drive the sleeve 23 to rotate. The sleeve 23 drives multiple scrapers 7 to make a circular motion along the inner side of the cleaning tank 5, sending the residual impurities and sewage on the bottom inner wall of the cleaning tank 5 into the drain hole. At the same time, the multiple scrapers 7 drive the mounting ring 28 to rotate, causing the mounting ring 28 to drive the rack 29 to make a circular motion. When the rack 29 contacts the gear 27, the gear 27 drives the driven rod 25 to rotate, causing the driven rod 25 to drive the fixed tube 24 to rotate through the prismatic tube 26, and compressing the coil spring 30. The fixed tube 24 drives the roller brush 8 to rotate, causing the roller brush 8 to clean the corrosive liquid residue and impurities on the outside of the mixing tank. When the rack 29 moves away from the gear 27... At the same time, the rebound force of the coil spring 30 causes the driven rod 25 to rotate, causing the roller brush 8 to reciprocate to clean the impurities on the surface of the mixing tank. Simultaneously, the fixed tube 24 drives multiple sliding balls 31 to move in a circular motion around the driven rod 25 as the center point, causing the sliding balls 31 to slide out of the spherical groove on the support plate 32. The reaction force of the sliding balls 31 pushes the fixed tube 24 to move along the outside of the prismatic tube 26, stretching the tension spring 33. As the fixed tube 24 rotates, the sliding balls 31 align with the spherical groove again. The rebound force of the tension spring 33 causes the fixed tube 24 to return to its original position, and the sliding balls 31 insert into the spherical groove. Thus, as the fixed tube 24 continues to rotate, the sliding balls 31 can repeatedly enter the spherical groove, causing the fixed tube 24 to move up and down reciprocally along the outside of the prismatic tube 26.The roller brush 8 quickly removes impurities from the outside of the mixing tank. Finally, the electric slide 10 removes the cleaned mixing tank from the current cleaning tank 5. The first motor 9 then drives the mounting plate 6 to rotate, causing the mounting plate 6 to move multiple electric slides 10 synchronously. The cleaned mixing tank moves to the bottom of the next testing tank 3 and is immersed in the testing tank 3 for testing. This achieves continuous testing of the mixing tank, thereby improving the testing efficiency and avoiding cross-contamination between multiple testing tanks 3, ensuring the accuracy of corrosion resistance testing on the surface of the mixing tank.
