[0019] As a further technical solution of the present invention, a spring is provided at the bottom end of the connecting shaft, and the spring is arranged outside the second rotating shaft.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. Through the mutual cooperation of the mixing component and the cleaning component in the present invention, when the multi-ratio preparation device needs to be cleaned, first connect to the water source through the connecting pipe and an external water pump. The water source is introduced into the cleaning ring through the connecting pipe and finally discharged from the nozzles after being split, so as to wash the inner wall of the mixing tank. When cleaning, start the motor. When the motor starts, it drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the rotation of the first gear. The rotation of the first gear drives the rotation of the cleaning ring. The rotation of the cleaning ring drives the rotation of the nozzles, so that the nozzles can comprehensively wash the inner wall of the mixing tank. At the same time, when the cleaning ring rotates, it drives the scraper to rotate along the inner wall of the mixing tank, which helps to scrape off the raw materials and dirt layers attached to the inner wall of the mixing tank, improves the cleaning effect on high-viscosity dirt, and thus improves the cleaning efficiency of the multi-ratio preparation device.

[0022] 2. Through the setting of the control plate rotating and opening in the present invention, when cleaning, when the water source enters the cleaning ring, the water pressure forces the connecting shaft to move downward. The movement of the connecting shaft drives the movement of the connecting plate. When the connecting shaft moves downward and contacts the convex block, the convex block is embedded at the bottom of the connecting shaft and pushes the connecting plate upward. The movement of the connecting plate drives the movement of the rack plate. The movement of the rack plate drives the rotation of the second gear. The rotation of the second gear drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the control plate, opening the opening at the top of the connecting shaft, facilitating the water source to enter the second rotating shaft from it and finally discharging from the flushing port to wash the inner wall of the mixing tank, improving the cleaning effect.

[0023] 3. Through the setting of the scraper rotating during cleaning in the present invention, when the connecting shaft moves downward, the movement of the connecting shaft drives the movement of the slider. When the slider moves, it guides the second rotating shaft to rotate through the chute. The rotation of the second rotating shaft drives the rotation of the scraper, making the scraper rotate 180 degrees, so that the flushing port is located on one side of the mixing blade, facilitating the flushing of the mixing blade and improving the comprehensiveness of flushing.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 7 shown, in the embodiment of the present invention, a multi-ratio preparation device for producing petroleum sulfonic acid blend includes a mixing tank 1. A mixing component and a cleaning component are arranged inside the mixing tank 1. A tank cover 2 is installed at the top of the mixing tank 1. A proportioning tank 3 is arranged at the top of the tank cover 2. A discharge pipe 4 is fixedly installed at the bottom of the mixing tank 1;

[0034] The mixing component includes a mixing shaft 6 arranged inside the mixing tank 1. The top of the mixing shaft 6 is connected to a motor 5. Mixing blades 7 are fixedly installed on the outer wall of the mixing shaft 6;

[0035] The cleaning component includes a cleaning ring 8 disposed inside the mixing tank 1. A connecting ring 9 is embedded at the top end of the cleaning ring 8. A connecting pipe 10 is fixedly connected to the top end of the connecting ring 9. Nozzles 11 are uniformly installed at the bottom of the cleaning ring 8 in an annular array. A scraping plate 15 is installed at the bottom end of the cleaning ring 8.

[0036] One side of the cleaning ring 8 is meshed with a first gear 12. A first rotating shaft 13 is fixedly installed inside the first gear 12. A motor 14 is installed at the top end of the first rotating shaft 13.

[0037] Existing: CN221808918U discloses a casting resin sand proportioning device. The mixing tank 1, tank cover 2, proportioning tank 3, and discharge pipe 4 proposed in the present application document are disclosed in this patent. These technical means will not be elaborated one by one here.

[0038] One end of the connecting pipe 10 away from the tank cover 2 is connected to an external water pump. After the water pump is connected to the water source, it flushes the inside of the mixing tank 1.

[0039] When it is necessary to clean the multi-proportioning device, first connect the connecting pipe 10 to an external water pump and connect to the water source. The water source is introduced into the cleaning ring 8 through the connecting pipe 10 and finally splits and discharges from the nozzles 11, thereby flushing the inner wall of the mixing tank 1.

[0040] When cleaning, start the motor 14. When the motor 14 starts, it drives the first rotating shaft 13 to rotate. The rotation of the first rotating shaft 13 drives the rotation of the first gear 12. The rotation of the first gear 12 drives the rotation of the cleaning ring 8. The rotation of the cleaning ring 8 drives the rotation of the nozzles 11, so that the nozzles 11 comprehensively flush the inner wall of the mixing tank 1.

[0041] At the same time, when the cleaning ring 8 rotates, it drives the scraping plate 15 to rotate along the inner wall of the mixing tank 1, which helps to scrape off the raw materials and dirt layers attached to the inner wall of the mixing tank 1, improves the cleaning effect on high-viscosity dirt, and thus improves the cleaning efficiency of the multi-proportioning device.

[0042] As Figures 3 to 6 shown, the cleaning ring 8 is rotatably connected to the connecting ring 9.

[0043] During the rotation of the cleaning ring 8, the connecting ring 9 is always located at the top to ensure the stability during connection.

[0044] As Figure 2 shown, the scraping plate 15 is disposed on one side of the mixing blade 7. The scraping plate 15 is slidably fitted with the inner wall of the mixing tank 1.

[0045] As Figures 2 to 6 shown, a second rotating shaft 16 is fixedly connected to the top end of the scraping plate 15. The second rotating shaft 16 is embedded at the bottom of the cleaning ring 8. Flushing ports 28 are evenly formed inside the scraping plate 15.

[0046] As shown Figure 6 and Figure 7 in FIG. 1, a connecting shaft 17 is provided below the connecting pipe 10. The connecting shaft 17 is installed inside the cleaning ring 8. A control board 18 is installed on the inner wall of the connecting shaft 17. Third rotating shafts 19 are fixedly connected to both sides of the control board 18. A second gear 20 is fixedly installed at one end of one of the third rotating shafts 19. A rack plate 22 is meshed and connected to one side of the second gear 20. A connecting plate 23 is fixedly connected to the bottom end of the rack plate 22. A convex block 24 is provided below the connecting plate 23. The convex block 24 is fixedly installed on the inner wall of the cleaning ring 8.

[0047] During cleaning, when water enters the cleaning ring 8, the water pressure forces the connecting shaft 17 to move downward. The movement of the connecting shaft 17 drives the movement of the connecting plate 23. When the connecting shaft 17 moves downward and contacts the convex block 24, the convex block 24 is embedded in the bottom of the connecting shaft 17 to push the connecting plate 23 upward. The movement of the connecting plate 23 drives the movement of the rack plate 22. The movement of the rack plate 22 drives the rotation of the second gear 20. The rotation of the second gear 20 drives the rotation of the third rotating shaft 19. The rotation of the third rotating shaft 19 drives the rotation of the control board 18, opening the opening at the top of the connecting shaft 17, facilitating the entry of water from it into the second rotating shaft 16, and finally discharging from the flushing port 28 to flush the inner wall of the mixing tank 1, improving the cleaning effect.

[0048] As shown Figure 7 in FIG. 2, the connecting shaft 17 is slidably connected to the cleaning ring 8.

[0049] As shown Figure 7 in FIG. 3, the flushing port 28 is arranged to incline downward, and the opening of the flushing port 28 faces one side of the mixing tank 1.

[0050] The downward inclination can utilize the gravity effect to make the water flow downward naturally, enhancing the flushing effect.

[0051] As shown Figure 7 in FIG. 4, a torsion spring 21 is installed on the outer wall of the other third rotating shaft 19.

[0052] During flushing, when the control board 18 rotates and opens, the third rotating shaft 19 rotates to deform the torsion spring 21 to store elastic potential energy. After flushing, the elastic potential energy is released by the torsion spring 21 to make the control board 18 rotate in the reverse direction to reset.

[0053] As shown Figure 7 in FIG. 5, the connecting shaft 17 is sleeved on the outer wall of the second rotating shaft 16. A slider 25 is fixedly installed on the inner wall of the connecting shaft 17. The slider 25 is embedded in the inner wall of a chute 26. The chute 26 is opened on the outer wall of the second rotating shaft 16.

[0054] When the connecting shaft 17 moves downward, the movement of the connecting shaft 17 drives the movement of the slider 25. When the slider 25 moves, it is guided by the chute 26 to make the second rotating shaft 16 rotate. The rotation of the second rotating shaft 16 drives the rotation of the scraper 15, causing the scraper 15 to rotate 180 degrees, so that the flushing port 28 is located on one side of the mixing blade 7, facilitating the flushing of the mixing blade 7 and improving the comprehensiveness of flushing.

[0055] As Figure 7 shown, a spring 27 is provided at the bottom end of the connecting shaft 17, and the spring 27 is arranged outside the second rotating shaft 16.

[0056] During cleaning, when the connecting shaft 17 moves downward due to water pressure, the spring 27 deforms to store elastic potential energy. After flushing, the elastic potential energy is released by the spring 27 to make the connecting shaft 17 move upward and reset;

[0057] Similarly, the scraper 15 reverses, so that the outlet of the flushing port 28 faces the inner wall of the mixing tank 1, preventing raw materials from entering during mixing.

[0058] Working principle and usage process:

[0059] When the multi-ratio preparation device needs to be cleaned, first connect it to an external water pump through the connecting pipe 10 and introduce water. The water source is introduced into the cleaning ring 8 through the connecting pipe 10 and finally splits and discharges from the nozzles 11, so as to flush the inner wall of the mixing tank 1;

[0060] During flushing, when the water source enters the cleaning ring 8, the water pressure forces the connecting shaft 17 to move downward. The movement of the connecting shaft 17 drives the movement of the slider 25. When the slider 25 moves, it is guided by the chute 26 to make the second rotating shaft 16 rotate. The rotation of the second rotating shaft 16 drives the rotation of the scraper 15, causing the scraper 15 to rotate 180 degrees, so that the flushing port 28 is located on one side of the mixing blade 7;

[0061] At the same time, the movement of the connecting shaft 17 drives the movement of the connecting plate 23. When the connecting shaft 17 moves downward and contacts the convex block 24, the convex block 24 is embedded in the bottom of the connecting shaft 17 to push the connecting plate 23 upward. The movement of the connecting plate 23 drives the movement of the rack plate 22. The movement of the rack plate 22 drives the rotation of the second gear 20. The rotation of the second gear 20 drives the rotation of the third rotating shaft 19. The rotation of the third rotating shaft 19 drives the rotation of the control plate 18, opening the opening at the top of the connecting shaft 17 to facilitate the water source to enter the second rotating shaft 16 from it and finally discharge from the flushing port 28 to flush the mixing blade 7;

[0062] When flushing, start the motor 14. When the motor 14 starts, it drives the first rotating shaft 13 to rotate. The rotation of the first rotating shaft 13 drives the rotation of the first gear 12. The rotation of the first gear 12 drives the rotation of the cleaning ring 8. The rotation of the cleaning ring 8 drives the rotation of the nozzles 11, so that the nozzles 11 comprehensively flush the inner wall of the mixing tank 1;

[0063] Meanwhile, when the cleaning ring 8 rotates, it drives the scraper 15 to rotate along the inner wall of the mixing tank 1, which helps to scrape off the raw materials and dirt layers attached to the inner wall of the mixing tank 1, and to flush the outer wall of the mixing blade 7 through the flushing port 28.

[0064] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
