[0001] This utility model relates to the field of organosilicon emulsion production technology, specifically to a stirring tank for producing anti-blocking organosilicon emulsion. Background Technology
[0002] Organosilicon emulsions are emulsions with organosilicon compounds as the main component, dispersed in water or other liquid media in the form of tiny droplets. In the production process, organosilicon compounds, emulsifiers, water, and other additives need to be stirred and mixed in a mixing tank to carry out the reaction.
[0003] The publication number CN216458264U discloses a mixing tank with an anti-sticking structure for the production of organosilicon emulsions, including a tank body and a scraper. Feed hoppers are provided on the upper left and right sides of the tank body, and a motor is installed at the top of the tank body. A humidity detector is installed on the left side of the tank body.
[0004] The aforementioned mixing tank facilitates the replacement and cleaning of the filter frame by the staff. However, during the mixing process, the scraper continuously scrapes the material as it rotates with the mixing blades, which can easily cause wear on the inner wall of the tank. Furthermore, the raw materials in the emulsion can easily rotate synchronously with the mixing blades, reducing the mixing efficiency of the emulsion. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] Combination Figures 1-5 A mixing tank for producing anti-adhesion silicone emulsion includes a tank body 1, a scraping mechanism 2 installed inside the tank body 1, and a mixing mechanism 3 installed outside the scraping mechanism 2.
[0026] See Figure 3 and Figure 4 Furthermore, the scraping mechanism 2 includes a fixed frame 4 and a shaft 8. The fixed frame 4 is fixedly installed on the top of the tank body 1. A lifting cylinder 5 is installed on the top of the fixed frame 4. A lifting seat 6 is movably installed inside the fixed frame 4. A motor 7 is installed inside the lifting seat 6. The shaft 8 is fixedly installed at the bottom end of the output shaft of the motor 7. A sliding groove 9 is opened at the bottom end of the tank body 1. Two toothed discs 10 are movably installed and two toothed discs 10 are fixedly installed on the outside of the shaft 8. Two connecting rods 11 are fixedly installed on the outside of the two toothed discs 10 that are sleeved on the outside of the shaft 8. A scraper 12 is fixedly installed between the outer ends of the two connecting rods 11 located at the upper and lower ends. A positioning rod 13 is movably installed through the top of the tank body 1.
[0027] The lifting seat 6 is fixedly installed at the bottom of the telescopic rod of the lifting cylinder 5. The lifting seat 6 is located inside the fixed frame 4 and is slidably arranged up and down. The positioning rod 13 is threadedly connected to the top of the tank body 1. The lifting seat 6 is driven to slide up and down by the lifting cylinder 5, which in turn drives the motor 7 to slide the shaft 8 up and down.
[0028] The shaft 8 passes through the top of the tank body 1 and is slidably installed up and down. The gear plate 10, which is sleeved on the outside of the shaft 8, is slidably connected to the shaft 8. When the shaft 8 slides up and down, the gear plate 10 sleeved on the outside of the shaft 8 remains stationary.
[0029] The outer side of the scraper 12 slides on the inner wall of the tank body 1. The toothed disc 10 sleeved on the outside of the shaft 8 and the toothed disc 10 fixed on the outside of the shaft 8 are meshed with each other. After the toothed disc 10 is meshed, the shaft 8 drives the outer toothed disc 10 to rotate, so that the toothed disc 10 sleeved on the outside of the shaft 8 rotates accordingly.
[0030] Specifically, the motor 7 drives the shaft 8 to slide downward through the lifting seat 6, so that the toothed disc 10 fixed outside the shaft 8 meshes with the toothed disc 10 sleeved outside the shaft 8, thereby driving the scraper 12 to rotate. The scraper 12 scrapes off the material adhering to the inner wall of the tank 1. The motor 7 drives the shaft 8 to rise, so that the toothed disc 10 disengages. During the stirring process, the scraper 12 is prevented from continuously scraping the material, which would cause wear on the inner wall of the tank 1.
[0031] Example 2
[0032] See Figure 5 Furthermore, based on Embodiment 1, the stirring mechanism 3 includes a central rod 14, which is movably installed inside the shaft 8. Several fixed disks 15 are fixedly installed on the outside of the shaft 8. A slider 16 is fixedly installed at the bottom end of the central rod 14. Two stirring blades 17 are movably installed on the outside of each fixed disk 15. Conical teeth 18 are fixedly installed at the inner end of the rotating shaft of each stirring blade 17 and at the corresponding position on the outside of the central rod 14.
[0033] The central rod 14 is movably connected inside the shaft 8. The slider 16 and the slide groove 9 have rectangular cross-sections. The slider 16 is located in the slide groove 9 and is slidably positioned. The shaft 8 drives the central rod 14 to rise and fall synchronously. The slider 16 prevents the central rod 14 from rotating with the shaft 8.
[0034] The stirring blade 17 is located outside the fixed disk 15 and is rotatably connected by a rotating shaft. The bevel teeth 18 at the inner end of the rotating shaft of the stirring blade 17 are meshed with the bevel teeth 18 on the outside of the central rod 14. The shaft 8 drives the stirring blade 17 to rotate around, and the stirring blade 17 is rotated by the bevel teeth 18.
[0035] Specifically, the center rod 14 moves up and down synchronously with the shaft 8 via the slider 16 without rotating. When the shaft 8 drives the stirring blade 17 to rotate around, the conical teeth 18 of the stirring blade 17 rotate through the conical teeth 18 outside the center rod 14, thereby improving the stirring efficiency of the emulsion during the rotation process.
[0036] In actual operation, the raw materials used to produce silicone emulsion are added into tank 1, and the raw materials are stirred and mixed by stirring blade 17 to react. The emulsion adhering to the inner wall of tank 1 is scraped off by scraper 12.
[0037] During cleaning, the motor 7 drives the shaft 8 and the stirring blade 17 to rotate and stir the raw materials. The lifting cylinder 5 drives the lifting seat 6 to slide up and down, which in turn drives the motor 7 to slide up and down the shaft 8. This causes the toothed disc 10 fixed outside the shaft 8 to mesh with the toothed disc 10 sleeved outside the shaft 8. When the shaft 8 rotates, it drives the scraper 12 to rotate. The scraper 12 scrapes off the material adhering to the inner wall of the tank 1. The lifting cylinder 5 drives the motor 7 and the shaft 8 to rise, causing the toothed disc 10 to disengage. The positioning rod 13 slides down under the action of the thread. The bottom end of the positioning rod 13 blocks the connecting rod 11 to prevent the scraper 12 from rotating. This prevents the scraper 12 from continuously scraping the material during the stirring process and causing wear on the inner wall of the tank 1.
[0038] During stirring, the central rod 14 rises and falls synchronously with the shaft 8. The slider 16 slides within the groove 9, allowing the central rod 14 to rise and fall synchronously with the shaft 8 without rotating. The conical teeth 18 of the stirring blade 17 mesh with the conical teeth 18 on the outside of the central rod 14. When the shaft 8 drives the stirring blade 17 to rotate, the meshing of the conical teeth 18 causes the stirring blade 17 to rotate outside the fixed disk 15, thereby improving the stirring efficiency of the emulsion during rotation.
[0039] Although embodiments of the present 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 the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
