[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 - Figure 5 A reaction vessel for preparing aluminum ferric chloride water purification agent includes: a reaction vessel cylinder 1, a transmission assembly 5, and a wall scraping assembly 8. The reaction vessel cylinder 1 contains aluminum ferric ions that hydrolyze and polymerize to form a high molecular polymer. The transmission assembly 5 includes an outer shell 51, with two drive rods 7 fixedly installed at the bottom of the outer shell 51. The wall scraping assembly 8 is located at the outer end of the drive rods 7 and includes a connecting block 82 and a fixing plate 86. A scraper 83 is fixedly connected to the outer end of the connecting block 82. A movable groove is opened on the inner side of the connecting block 82, and the connecting block 82 is sleeved on the outer end of the fixing plate 86 through the movable groove. The drive rods 7 are driven by the transmission assembly 5 to drive the wall scraping assembly 8 to rotate. The centrifugal force generated by the rotation of the connecting block 82 causes the scraper 83 to abut against the inner wall of the reaction vessel cylinder 1.

[0037] The top of the reactor body 1 is detachably fitted with a cover 4. Inside the cover 4 is a drive assembly 6. A partition 12 is fixedly installed on the inner side of the cover 4. The cover 4 isolates the drive assembly 6 and the transmission assembly 5 on the inner side through the partition 12. The bottom of the reactor body 1 is provided with a discharge port 11, and the top of the cover 4 is provided with a feed port 3.

[0038] Aluminum ferric chloride water purifier is a highly efficient inorganic polymeric flocculant that transforms aluminum and iron raw materials into polymers with water purification functions through specific chemical reactions. The device in this scheme is mainly used to accommodate the chemical reaction, utilizing polymerization and hydrolysis, and promoting the hydrolysis and polymerization of aluminum and iron ions through stirring to form a polymer.

[0039] The reactor body 1 is a container for the reaction. A cover 4 is detachably installed on the top of the reactor body 1. The cover 4 can be installed on the reactor body 1 by bolts or clips. A partition 12 is fixed inside the cover 4. The partition 12 is mainly used to isolate the transmission assembly 5 and the drive assembly 6 inside the cover 4. At the same time, a round hole is opened in the center of the partition 12 so that the transmission assembly 5 can drive the stirring and scraping device located inside the reactor body 1.

[0040] A discharge port 11 is provided at the bottom of the reactor body 1. A valve is installed on the discharge port 11 to control the discharge. The reacted material can be released through the discharge port 11. A feed port 3 is provided at the top of the cover 4. The feed port 3 is mainly used for feeding materials. It is worth mentioning that a guide plate is fixed on the inside of the cover 4. The guide plate is connected to the feed port 3 so that when materials are fed through the feed port 3, they will not come into contact with the transmission component 5 and the drive component 6.

[0041] Multiple wall-scraping components 8 are installed on both drive rods 7, and the wall-scraping components 8 on the two drive rods 7 are staggered. The drive rods 7 drive the wall-scraping components 8 to scrape the inner wall of the reactor body 1 by rotating the transmission component 5, so that the material adhering to the inner wall is hung off. At the same time, the scraper 83 is installed on the outer end of the fixed plate 86 through the connecting block 82. The fixing pin 84 installed on the connecting block 82 is slidably connected to the slide groove 87 on the fixed plate 86. When the drive rods 7 rotate, centrifugal force is generated, so that the connecting block 82 moves outward in the slide groove 87 through the fixing pin 84. The scraper 83 will always be pressed against the inner wall of the reactor body 1, so that it can always be in close contact with the inner wall of the reactor body 1.

[0042] Please see Figure 5 The wall scraping assembly 8 also includes a mounting sleeve 81, which is fixedly mounted on the outer end of the drive rod 7. A fixing plate 86 is fixedly mounted on the outer end of the mounting sleeve 81. The outer end of the fixing plate 86 is provided with equally spaced sliding grooves 87. The outer end of the connecting block 82 is provided with equally spaced through holes 85. A fixing pin 84 is fixedly mounted inside the through hole 85. The connecting block 82 is slidably connected to the sliding grooves 87 on the fixing plate 86 through the fixing pin 84.

[0043] In this design, the mounting sleeve 81 is fixed to the drive rod 7. The multiple scraping components 8 on the two drive rods 7 are vertically equidistant and staggered to cover more of the inner wall of the reactor body 1. The fixing plate 86 is fixed to the outer end of the mounting sleeve 81. Multiple sliding grooves 87 are vertically equidistant on the fixing plate 86. The scraper 83 is fixed to the outer end of the connecting block 82. The scraper 83 is made of plastic and has an arc-shaped outer surface so that it can fit against the inner wall of the reactor body 1.

[0044] An active groove is provided on the inner side of the connecting block 82. This active groove matches the fixed plate 86. The connecting block 82 can be sleeved on the outer end of the fixed plate 86 through the active groove. Multiple through holes 85 are provided on the outer end of the connecting block 82. A fixing pin 84 is fixed inside each through hole 85. The fixing pin 84 is slidably connected to the slide groove 87. The connecting block 82 can drive the scraper 83 to move outward by the cooperation of the fixing pin 84 and the slide groove 87.

[0045] When the drive rod 7 is driven to rotate by the transmission assembly 5, it can drive the scraper assembly 8 to rotate. When the scraper 83 and the connecting block 82 rotate, centrifugal force is generated. At this time, the connecting block 82 will drive the scraper 83 to move outward through the fixing pin 84, so that the scraper 83 can stick tightly to the inner wall of the reactor body 1. This can offset the errors generated during the processing and assembly of the parts, so that the scraper 83 can always stick tightly to the inner wall of the reactor body 1 when working. When not working, the scraper 83 will not stick tightly to the inner wall of the reactor body 1, and the scraper assembly 8 can be easily removed.

[0046] Please see Figure 2 and Figure 3 The drive assembly 6 includes a synchronous pulley 61 and a drive shaft 64. The synchronous pulley 61 is fixedly installed on the outer end of the drive shaft 64. The drive motor 2 is installed on the top of the cylinder cover 4. One end of the drive shaft 64 passes through the top of the cylinder cover 4 and is connected to the output end of the drive motor 2.

[0047] The drive assembly 6 also includes a synchronous gear ring 62 and a synchronous belt 63. The synchronous gear ring 62 is fixedly mounted on the outer surface of the housing 51, and the synchronous pulley 61 and the synchronous gear ring 62 are connected by the synchronous belt 63.

[0048] In this design, the drive assembly 6 is mainly used to drive the transmission assembly 5. The drive motor 2 is fixed on the top of the cylinder cover 4. The transmission shaft 64 is fixedly connected to the output end of the drive motor 2. The synchronous pulley 61 is fixed on the outer end of the transmission shaft 64, and the synchronous gear ring 62 is fixed on the outer edge of the outer shell 51. The synchronous gear ring 62 and the synchronous pulley 61 are connected by a synchronous belt 63. When the drive motor 2 drives the synchronous pulley 61 to rotate through the transmission shaft 64, the synchronous pulley 61 will drive the synchronous gear ring 62 through the synchronous belt 63, thereby allowing the outer shell 51 to rotate.

[0049] Please see Figure 3 and Figure 4 The transmission assembly 5 also includes a fixed shaft 52 and two mounting shafts 54. The fixed shaft 52 is fixedly installed inside the cylinder cover 4, and the two mounting shafts 54 are rotatably installed inside the outer shell 51. The outer shell 51 is rotatably installed on the outer end of the fixed shaft 52.

[0050] A fixed gear 53 is fixedly installed on the outer end of the fixed shaft 52. A driven gear 55 is fixedly connected to the outer ends of the two mounting shafts 54. The driven gear 55 meshes with the fixed gear 53. Both the driven gear 55 and the fixed gear 53 are located inside the outer shell 51. The bottom end of the mounting shaft 54 ​​passes through the bottom of the outer shell 51 and is fixedly connected to a drive rod 9. A stirring device 10 is fixedly installed on the outer end of the drive rod 9.

[0051] In this scheme, the transmission component 5 is mainly used to drive the stirring device 10 and the wall scraping component 8 to rotate. The fixed shaft 52 is fixed to the top of the inner side of the cylinder cover 4 and is non-rotatable. At the bottom of the fixed shaft 52, the fixed gear 53 is fixed and is also non-rotatable. The outer shell 51 is rotatably installed on the outer end of the fixed shaft 52, so that the outer shell 51 can rotate around the fixed shaft 52. The stirring device 10 is mainly composed of multiple stirring blades connected to each other.

[0052] Inside the outer casing 51, two mounting shafts 54 are rotatably mounted. The top of the mounting shafts 54 is rotatably connected to the top of the inner side of the outer casing 51. At the same time, a driven gear 55 is fixed at the outer end of each of the two mounting shafts 54. Both driven gears 55 are meshed with the fixed gear 53. Both mounting shafts 54 pass through the bottom of the outer casing 51 and are fixedly connected to the second drive rod 9. Multiple stirring devices 10 are fixed on the second drive rod 9. These multiple stirring devices 10 are installed in the same way as the wall scraping assembly 8, which are all installed in a staggered manner. The two drive rods 7 are fixed to the bottom of the outer casing 51.

[0053] When the synchronous gear ring 62 drives the outer shell 51 to rotate around the fixed shaft 52, since the fixed shaft 52 and the fixed gear 53 are fixed, the outer shell 51 will drive the two mounting shafts 54 to rotate around the fixed shaft 52. At this time, through the meshing of the driven gear 55 and the fixed gear 53, the mounting shaft 54 ​​can rotate and also rotate on its own axis, so that the drive rod 9 drives the stirring device 10 to rotate and rotate on its own axis. Compared with the traditional method of only rotating on its own axis, the stirring amplitude can be larger, and the material can be stirred more evenly, improving uniformity. At this time, the rotating outer shell 51 will also drive the drive rod 7, so that the wall scraping assembly 8 scrapes the material on the inner wall of the reactor cylinder 1.

[0054] Working principle: When preparing aluminum ferric chloride, after the material is put into the reactor body 1, the drive motor 2 can be started. The drive motor 2 drives the synchronous pulley 61 to rotate through the transmission shaft 64. The synchronous pulley 61 drives the synchronous gear ring 62 through the synchronous belt 63, so that the outer shell 51 can rotate. The outer shell 51 will drive the two mounting shafts 54 to rotate around the fixed shaft 52. At this time, through the meshing of the driven gear 55 and the fixed gear 53, the mounting shaft 54 ​​can rotate and rotate on its own, so that the stirring device 10 can rotate and rotate on its own at the same time, which can stir the material more evenly. At the same time, the drive rod 7 is driven to rotate by the outer shell 51. When the scraper 83 and the connecting block 82 rotate, centrifugal force will be generated. At this time, the connecting block 82 will drive the scraper 83 to move outward through the fixed pin 84, so that the scraper 83 can always be in close contact with the inner wall of the reactor body 1 during operation.
