Description

Technical Field

[0001] The invention relates to the technical field of chemical raw material processing, in particular to chemical raw material mixing reaction equipment. Background Art

[0002] Chemical raw materials refer to the initial substances used for various chemical reactions and processes in the chemical industry. These raw materials can be of natural origin, such as minerals, petroleum, natural gas, biomass, etc., or they can be chemicals prepared by other chemical processes. The mixing reaction of chemical raw materials is a core process in the chemical industry, which involves mixing two or more different chemical substances in specific proportions and conditions to produce new compounds or materials through chemical reactions. The mixing effect of chemical raw materials is not only related to the quality of the final product, but also involves many aspects such as production safety, economic benefits and environmental impact. Therefore, in chemical production, it is crucial to ensure the uniform and sufficient mixing of raw materials.

[0003] However, the following problems still exist in the process of mixing chemical raw materials: 1. It is common to use a driving shaft to directly drive the stirring rod to rotate to complete the mixing of chemical raw materials. In this way, the stirring rod is only supported by the rotating shaft. When mixing a large amount of chemical raw materials, the stirring rod is subject to greater resistance from the chemical raw materials, which will affect the structural strength of the connection point between the stirring rod and the rotating shaft. After long-term use, the overall stability of the stirring structure is easily reduced, and the service life is shortened, which is not conducive to the control of the cost of the processing equipment.

[0004] 2. When stirring is performed only by circumferential rotation of the stirring rod, the stirring force and stirring range acting on the chemical raw materials are insufficient, and it is difficult to ensure the uniformity and activity of the mixing of the chemical raw materials, which leads to a decrease in the mixing quality and mixing efficiency of the chemical raw materials. Summary of the invention

[0005] The present invention provides a chemical raw material mixing and reacting device, which includes a reaction tank. A tank cover is arranged at the upper end of the reaction tank, and two semi-circular bottom plates distributed left and right are arranged at the lower end of the reaction tank. A stirring unit is arranged at the lower end of the tank cover; an installation component is arranged between the reaction tank and the tank cover. The installation component includes a fixing ring fixedly sleeved outside the reaction tank. A circumferentially uniformly arranged installation column is installed at the lower end of the tank cover, and a limiting member is arranged at the lower end of the installation column; the stirring unit includes a central shaft rotatably installed at the center of the tank cover and on the left side of the feed port. A stirring component is arranged under the tank cover and is uniformly arranged up and down along the central shaft. The stirring component includes an installation ring sleeved outside the central shaft. The installation ring at the uppermost position is slidably connected to the central shaft up and down, and the rest of the installation rings are fixedly connected to the central shaft. Except for the uppermost installation ring, stirring members are arranged circumferentially and uniformly on the outer sides of the rest of the installation rings.

[0008] In a possible implementation manner, side scraping rods are hinged to the ends of the stirring rods far from the central shaft. Slots are opened on the sides of the rest of the side scraping rods far from the central shaft. The width dimension of the slot along the radial direction of the reaction tank is much larger than the width dimension of the insertion piece along the radial direction of the reaction tank. Except for the lowermost side scraping rod, insertion pieces for cooperating with the corresponding slots are installed at the lower ends of the rest of the side scraping rods. Bottom scraping rods are circumferentially and uniformly arranged on the outer side of the lower end of the central shaft. An inverted U-shaped groove for slidingly matching with the corresponding bottom scraping rod is opened at the lower end of the lowermost side scraping rod. The internal height of the inverted U-shaped groove is much larger than the thickness of the bottom scraping rod. Annular grooves for slidingly matching with the bottom scraping rods are opened at the positions of the inner wall of the reaction tank corresponding to the bottom scraping rods.

[0009] In one possible implementation, a vertical rod that slides through the lowest mounting ring is installed on the upper end of the bottom scraper rod near the central axis, and a support plate is installed on one end of the vertical rod near the central axis. Vertical grooves that slide with the vertical rod are provided at positions on the central axis corresponding to the vertical rods, and connecting springs that are evenly arranged up and down are connected between the side walls of the vertical grooves and the vertical rods. A shift rod is installed on the side of the stirring rod in the lowest stirring assembly near the central axis, and the upper end of the shift rod is inclined upward, and the support plate conflicts with the inclined surface of the corresponding shift rod away from the axis of the central axis. A shifting groove for avoiding the rotation of the shift rod is provided on the vertical rod, and an avoidance groove for avoiding the vertical rod and the shift rod is provided on the lowest mounting ring. The upper ends of the left and right semicircular bottom plates are jointly provided with matching grooves that rotate with the lower end of the central axis.

[0010] In one possible implementation, the driving assembly includes a rotating gear installed after the upper end of the central shaft rotates through the tank cover, and a driving gear rotatably installed on the upper end of the tank cover is meshed with the rear side of the rotating gear. The upper end of the driving gear is connected to the output shaft of the motor, and the motor is installed on the upper end of the tank cover through a support.

[0011] In one possible implementation, a control component for controlling the uppermost mounting ring to move up and down along the central axis is disposed inside the upper end of the central axis, the control component includes a threaded column connected to the internal thread of the upper end of the central axis, a control circular plate is rotatably mounted on the lower end of the threaded column and cooperates with the central axis to slide up and down, control rods are mounted on the outer ring surface of the control circular plate and are evenly arranged circumferentially and fixedly connected to the inner ring surface of the uppermost mounting ring, and positions on the central axis corresponding to the control rods are provided with strip-shaped through grooves connected to the control rods to slide up and down.

[0012] In one possible implementation, a conical sleeve mounted on the central axis is installed on the upper end of the mounting ring, a protective sleeve mounted between the central axis and the conical sleeve and used to shield the strip-shaped through groove is installed on the upper end of the uppermost mounting ring, and a sliding through hole is provided on the conical sleeve below the connecting column to slide up and down with the connecting column.

[0013] In one possible implementation, a rotating ring is rotatably installed on the inner side of the tank cover, and balls that are evenly arranged in the circumference are rollingly installed on the lower end of the rotating ring. A circular groove that cooperates with the balls in rolling is opened on the upper end of the reaction tank, and a guide groove plate that is located on the inner side of the balls and evenly arranged in the circumference is installed on the lower end of the rotating ring. A top rod that is coaxially hinged with the corresponding auxiliary rod is hinged on the top mounting ring, and a pin rod that is slidably connected to the corresponding guide groove plate is hinged on the other end of the top rod.

[0015] Beneficial effects of the present invention: 1. The present invention utilizes the wall of the reaction tank to provide support and guidance for the stirring assembly during mixing and stirring, thereby ensuring that the stirring assembly is evenly stressed and improving the relative stability between the stirring assembly and the reaction tank. At the same time, the connecting pieces arranged between the upper and lower adjacent stirring assemblies help to increase the structural stability between the upper and lower adjacent stirring assemblies. A highly stable connection structure is maintained between the stirring assembly and the reaction tank / tank cover, between the reaction tank and the tank cover, between the upper and lower adjacent stirring assemblies, and between the stirring assembly and the driving assembly, thereby improving the overall stability and reliability of the stirring unit during operation, thereby effectively improving the efficiency and effect of the stirring assembly on mixing chemical raw materials.

[0016] 2. The installation assembly adopted in the present invention can not only guide and support the tank cover during the installation process through the cooperation between the installation column and the fixing ring, but also limit the tank cover circumferentially. At the same time, the tank cover placed on the upper end of the reaction tank is limited up and down by the limiting member. This method of fixing the tank cover is not only simple and convenient, but also has high installation efficiency. It can also increase the relative stability between the tank cover and the reaction tank, ensuring that the tank cover is stably and reliably fixed on the upper end of the reaction tank, which is conducive to the subsequent effective and stable stirring and mixing operations.

[0017] 3. The stirring unit in the present invention can stir and mix the chemical raw materials by using the stirring components evenly arranged up and down, and the stirring parts and connecting parts evenly arranged circumferentially can further increase the stirring force of the stirring components to mix the chemical raw materials, improve the activity and mixing uniformity of the chemical raw materials, and thus improve the mixing quality and mixing efficiency of the chemical raw materials.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] See also Figure 1 and Figure 2A chemical raw material mixing reaction equipment comprises a reaction tank 1, a tank cover 2 is arranged at the upper end of the reaction tank 1, a feed port is opened at the upper end of the tank cover 2, two semicircular bottom plates 11 distributed on the left and right are arranged at the lower end of the reaction tank 1, and a stirring unit 21 is arranged at the lower end of the tank cover 2 (the feed port can be connected to the existing feeding equipment through a pipeline, and the two semicircular bottom plates 11 on the left and right at the lower end of the reaction tank 1 can be controlled to open / close by the existing electric control equipment, and the feeding equipment and the electric control equipment are not shown in the figure).

[0031] See also Figure 1 , Figure 2 and Figure 3 A mounting assembly is arranged between the reaction tank 1 and the tank cover 2, and the mounting assembly includes a fixing ring 12 fixedly sleeved on the outside of the reaction tank 1, and a mounting column 121 evenly arranged in the circumferential direction is installed at the lower end of the tank cover 2. A mounting through hole that slides up and down with the mounting column 121 is provided on the fixing ring 12, and a limiting member is provided at the lower end of the mounting column 121. The limiting member includes a limiting ring 122 installed on the outside of the mounting column 121, and a mounting groove 123 located below the limiting ring 122 and evenly arranged in the circumferential direction is provided on the mounting column 121. A trapezoidal slider 124 with an inclined section facing downward is slidably installed in the mounting groove 123, and a telescopic spring 125 evenly arranged up and down is connected between the trapezoidal slider 124 and the side wall of the mounting groove 123.

[0032] Before adding chemical raw materials into the reaction tank 1 for mixing reaction, the tank cover 2 can be moved down by existing equipment or manually to place the stirring unit 21 in the reaction tank 1, and the circumferentially arranged mounting posts 121 are synchronously moved down with the tank cover 2 and gradually inserted into the corresponding mounting through holes. In this process, the trapezoidal sliders 124 evenly arranged circumferentially at the lower ends of the mounting posts 121 first contact the fixing ring 12, and the trapezoidal sliders 124 are subjected to the extrusion force to compress the telescopic springs 125 and move along the mounting grooves 123 to the inside of the mounting posts 121, so that the mounting posts 121 drive the trapezoidal sliders 124 to pass through the mounting through holes. After passing through the mounting through holes, the trapezoidal sliders 124 can be reset under the action of the telescopic springs 125, and at this time, the limiting rings 122 contact the fixing rings 12. Pressed on the upper end of the fixing ring 12, the tank cover 2 is just pressed on the upper end of the reaction tank 1. The cooperation between the mounting column 121 and the mounting through hole can not only guide and support the downward movement of the tank cover 2, but also limit the circumferential position of the tank cover 2. The mounting column 121 and the tank cover 2 can be limited up and down through the cooperation of the limiting ring 122 and the trapezoidal block. The method of fixing the tank cover 2 is not only simple and convenient, but also can increase the relative stability between the tank cover 2 and the reaction tank 1, ensuring that the tank cover 2 is stably and reliably pressed on the upper end of the reaction tank 1, thereby improving the stability of the stirring unit 21. When the tank cover 2 needs to be moved up later, the trapezoidal slider 124 can be pressed into the mounting groove 123 with the help of external force, so that the mounting column 121 can be smoothly separated from the fixing ring 12.

[0033] See also Figure 2 , Figure 4 and Figure 7 The stirring unit 21 includes a central shaft 22 rotatably mounted at the center of the tank cover 2 and located on the left side of the feed port, and the upper ends of the left and right semicircular bottom plates 11 are jointly provided with a matching groove that is rotatably matched with the lower end of the central shaft 22. A stirring assembly evenly arranged up and down along the central shaft 22 is arranged below the tank cover 2, and the stirring assembly includes a mounting ring 221 sleeved on the outside of the central shaft 22, the mounting ring 221 located at the top is slidably connected to the central shaft 22 up and down, and the remaining mounting rings 221 are fixedly connected to the central shaft 22. Except for the top mounting ring 221, the outer sides of the remaining mounting rings 221 are provided with stirring members evenly arranged in the circumferential direction, and the stirring member includes a stirring rod 222 hingedly connected to the mounting ring 221. The inner wall of the reaction tank 1 corresponding to the stirring assembly is provided with an annular inclined groove 223 that is rotatably matched with the corresponding stirring rod 222. The stirring rod 22 An inclined auxiliary rod 224 is hinged on the upper end of the auxiliary rod 224 through a pin shaft, and the pin shaft is slidably connected to the stirring rod 222. The upper end of the auxiliary rod 224 is hinged to the corresponding mounting ring 221. The auxiliary rod 224 and the stirring rod 222 corresponding to the same mounting ring 221 share a hinge axis. A connecting piece is provided between the upper and lower adjacent stirring pieces. The connecting piece includes an inclined rod 225. Except for the uppermost auxiliary rod 224, the other auxiliary rods 224 are hinged with an inclined rod 225. The other end of the inclined rod 225 is hinged to the lower end of the corresponding stirring rod 222. The lower end of the uppermost mounting ring 221 is equipped with connecting columns 226 that are evenly arranged around the central axis 22. The upper end of the mounting ring 221 is equipped with a conical sleeve 227 that is sleeved on the central axis 22. The conical sleeve 227 located below the connecting column 226 is provided with a sliding through hole that is slidably matched with the connecting column 226. The auxiliary rod 224 , the connected tilting rod 225 and the stirring rod 222 connected to the upper end of the auxiliary rod 224 form a triangular structure as a whole. The auxiliary rod 224 , the stirring rod 222 connected to its lower end and the central shaft 22 also form a triangular structure.

[0034] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A control component for controlling the uppermost mounting ring 221 to move up and down along the central shaft 22 is provided inside the upper end of the central shaft 22, and the control component includes a threaded column 228 connected to the inner thread of the upper end of the central shaft 22, and a control circular plate 229 is rotatably installed at the lower end of the threaded column 228 to slide up and down with the central shaft 22. Control rods that are evenly arranged in the circumference and fixedly connected to the inner surface of the uppermost mounting ring 221 are installed on the outer ring surface of the control circular plate 229, and bar-shaped through grooves 231 that are slidably connected to the control rods are provided at positions on the central shaft 22 corresponding to the control rods, and a protective sleeve 232 that is sleeved between the central shaft 22 and the conical sleeve 227 and is used to cover the bar-shaped through grooves 231 is installed on the upper end of the uppermost mounting ring 221.

[0035] During the process of the stirring unit 21 moving down into the reaction tank 1, the central shaft 22 drives the stirring components evenly arranged up and down to move synchronously into the reaction tank 1 until the lower end of the central shaft 22 is inserted into the matching groove jointly opened at the upper ends of the left and right semicircular bottom plates 11. During this process, the stirring rods 222 are in a state of tilting upward and not contacting the wall of the reaction tank 1, so that the stirring unit 21 can smoothly enter the reaction tank 1. The threaded column 228 can then be rotated to make the control circular plate 229 move downward along the central axis 22. The control circular plate 229 drives the uppermost mounting ring 221 to move downward along the central axis 22 through the control rod sliding downward along the strip groove 231. The protective sleeve 232 moves downward synchronously with the uppermost mounting ring 221 and blocks the outer side of the strip groove 231, so as to prevent the chemical raw materials from entering the strip groove 231 in the future. The uppermost mounting ring 221 drives the corresponding circumferentially arranged auxiliary rods 224 and the connecting column 226 to move downward synchronously. When the auxiliary rod 224 moves downward, it drives the pin shaft to slide accordingly along the corresponding stirring rod 222, and pushes the stirring rod 222 at its lower end through the pin shaft. The mixing rod 222 rotates, and the mixing rod 222 rotates downward around the hinge point between the mixing rod 222 and the corresponding mounting ring 221 until the end of the mixing rod 222 away from the central axis 22 rotates into the corresponding annular bevel groove 223. At this time, the connecting column 226 just passes through the sliding through hole on the corresponding conical sleeve 227 and presses against the corresponding mounting ring 221, so as to limit the uppermost mounting ring 221 and increase the connection stability between the uppermost mounting ring 221 and the mounting ring 221 below it. The conical sleeve 227 helps to avoid the subsequent accumulation of chemical raw materials on the upper end of the mounting ring 221. It should be noted that the mixing rod 222 only needs to rotate at a small angle to press into the corresponding annular bevel groove 223.

[0036] At the same time, the top stirring rod 222 can push the corresponding auxiliary rod 224 through the tilting rod 225 hinged at its lower end. The auxiliary rod 224 rotates downward around the hinge point between it and the corresponding mounting ring 221, and can use the same method as above to push the stirring rod 222 at its lower end to rotate synchronously into the corresponding annular bevel groove 223 through the pin shaft. By analogy, the stirring rods 222 in the stirring components evenly arranged up and down can be synchronously pressed into the corresponding annular bevel groove 223 in the same way, and the annular bevel groove 223 can be used for the subsequent rotation of the stirring rod 222 Providing support guidance and increasing the connection strength between the stirring rod 222 and the reaction tank 1, thereby improving the stability of the stirring assembly during operation; in addition, the tilting rod 225 and the auxiliary rod 224 can not only control the synchronous and stable rotation of the stirring rod 222, but also ensure that a stable triangular structure is formed between the upper and lower adjacent stirring rods 222 and between the stirring rod 222 and the mounting ring 221, thereby improving the overall structural strength and stirring stability of the stirring unit 21, and then increasing the subsequent stirring intensity of the chemical raw materials, further improving the activity and mixing uniformity of the chemical raw materials.

[0037] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 A rotating ring 233 is rotatably installed on the inner side of the tank cover 2, and balls 234 arranged evenly in the circumferential direction are rollingly installed on the lower end of the rotating ring 233. A circular groove 235 for rolling cooperation with the balls 234 is opened on the upper end of the reaction tank 1. A guide groove plate 236 located on the inner side of the balls 234 and arranged evenly in the circumferential direction is installed on the lower end of the rotating ring 233. A top rod 237 coaxially hinged to the corresponding auxiliary rod 224 is hinged on the top mounting ring 221, and a pin rod slidably connected to the corresponding guide groove plate 236 is hinged on the other end of the top rod 237.

[0038] When the top mounting ring 221 moves downward, it also drives the circumferentially evenly arranged push rod 237 to move downward. The other end of the push rod 237 can rotate around the pin and slide along the corresponding guide groove plate 236 through the pin. The cooperation between the push rod 237, the guide groove plate 236 and the pressure ring helps to further increase the connection stability between the stirring unit 21 and the tank cover 2. In the process of the tank cover 2 being pressed on the upper end of the reaction tank 1, the tank cover 2 can drive the rotating ring 233 to move downward to the upper end of the reaction tank 1 synchronously, and the circumferentially evenly arranged balls 234 move synchronously with the rotating ring 233 into the circular groove 235 at the upper end of the reaction tank 1. In the subsequent process of the central shaft 22 driving the evenly arranged stirring components up and down to rotate, the rotating ring 233 rotates synchronously with the top mounting ring 221 and the central shaft 22 through the push rod 237. The cooperation between the balls 234 and the circular groove 235 can not only reduce the friction between the rotating ring 233 and the upper end of the reaction tank 1, but also provide a guiding effect for the rotation of the rotating ring 233.

[0039] Please refer to Figure 2 , Figure 4 , Figure 7 and Figure 8 , one end of the stirring rod 222 far from the central axis 22 is hinged with a side scraping rod 238. Except for the uppermost side scraping rod 238, a slot 239 is provided on one side of the upper end of the remaining side scraping rods 238 far from the central axis 22. The width dimension of the slot 239 along the radial direction of the reaction tank 1 is much larger than the width dimension of the insertion piece 241 along the radial direction of the reaction tank 1. Except for the lowermost side scraping rod 238, insertion pieces 241 matched with the corresponding slots 239 are installed at the lower ends of the remaining side scraping rods 238. A bottom scraping rod 242 arranged circumferentially and evenly is provided on the outer side of the lower end of the central axis 22. An inverted U-shaped groove slidably matched with the corresponding bottom scraping rod 242 is provided at the lower end of the lowermost side scraping rod 238. The inner height of the inverted U-shaped groove is much larger than the thickness of the bottom scraping rod 242. Annular grooves slidably matched with the bottom scraping rod 242 are provided at the positions of the inner wall of the reaction tank 1 corresponding to the bottom scraping rod 242.

[0040] Please refer to Figure 2 , Figure 4 , Figure 7 and Figure 8 , a vertical rod 245 slidably penetrating through the lowermost mounting ring 221 is installed on the upper side of the bottom scraping rod 242 close to the central axis 22. A support plate 246 is installed at one end of the vertical rod 245 close to the central axis 22. Vertical grooves 248 slidably matched with the vertical rod 245 are provided at the positions of the central axis 22 corresponding to the vertical rod 245. Connecting springs 247 arranged evenly up and down are connected between the side walls of the vertical grooves 248 and the vertical rod 245. Stirring rods 222 in the lowermost stirring assembly are all provided with shifting rods 249 on the side close to the central axis 22. The upper ends of the shifting rods 249 are inclined upward, and the support plate 246 abuts against the inclined surface of the corresponding shifting rod 249 far from the axis of the central axis 22. A shifting through groove for avoiding the rotation of the shifting rod 249 is provided on the vertical rod 245. An avoidance groove for avoiding the vertical rod 245 and the shifting rod 249 is provided on the lowermost mounting ring 221.

[0041] The position where the side scraping rod 238 is hinged to the stirring rod 222 is above the center of gravity position of the side scraping rod 238 (as Figure 7As shown in the figure, the side scraping rod 238 can maintain a vertical state under its own gravity. During the process of the stirring unit 21 moving down into the reaction tank 1, the vertical side scraping rod 238 moves downward into the reaction tank 1 synchronously with the corresponding stirring rod 222. At this time, the lower end of the lowermost side scraping rod 238 has not yet contacted the semi-circular bottom plate 11. During the process of the stirring rod 222 rotating into the annular inclined groove 223, the corresponding side scraping rod 238 gradually approaches the inner wall of the reaction tank 1 while moving downward, and finally abuts tightly against the inner wall of the reaction tank 1, and the lower end of the lowermost side scraping rod 238 synchronously abuts against the upper end of the semi-circular bottom plate 11. In addition, the adjacent upper and lower side scraping rods 238 are matched with each other through the inserting piece 241 and the inserting slot 239. The moving side scraping rod 238 can drive the inserting piece 241 to move along the corresponding inserting slot 239 towards the inner wall of the reaction tank 1. Under the action of the inserting piece 241 and the inserting slot 239, the stability between the adjacent upper and lower side scraping rods 238 is improved synchronously; As Figure 7 shown, when the side scraping rod 238 abuts against the inner wall of the reaction tank 1, the inserting piece 241 is inserted into the corresponding inserting slot 239, and the side of the inserting piece 241 away from the center of the reaction tank 1 contacts the inner wall of the inserting slot 239 away from the center of the reaction tank 1. At this time, there is a sufficient distance between the side of the inserting piece 241 close to the center of the reaction tank 1 and the inner wall of the inserting slot 239 close to the center of the reaction tank 1.

[0042] During the process of the lowermost stirring rod 222 rotating downward around the hinge point between it and the corresponding mounting ring 221, the stirring rod 222 can synchronously drive the corresponding lever 249 to rotate upward. While the lever 249 rotates, it makes the vertical rod 245 move outward along the vertical groove 248 through the pressing support plate 246, and the connecting spring 247 elongates synchronously. The vertical rod 245 can drive the corresponding bottom scraping rod 242 to move outward synchronously. The bottom scraping rod 242 gradually inserts into the inverted U-shaped groove at the lower end of the corresponding side scraping rod 238, and finally enters the annular groove at the lower end of the reaction tank 1, so as to increase the connection degree and relative stability among the bottom scraping rod 242, the side scraping rod 238, and the reaction tank 1. It should be noted that the internal height of the inverted U-shaped groove is much larger than the thickness of the bottom scraping rod 242, so that the bottom scraping rod 242 can be smoothly inserted into the inverted U-shaped groove. The vertical rod 245 is always located in the vertical groove 248 before and after moving, so as to protect the connecting spring 247 inside the vertical groove 248.至此, the side scraping rods 238 are connected to each other as a whole, and this whole is simultaneously connected to the bottom scraping rod 242, that is, a whole is formed between the bottom scraping rod 242 and the corresponding side scraping rod 238 above it, and this whole is rotationally connected with the reaction tank 1 in a limited way, so as to ensure the stable rotation of the subsequent bottom scraping rod 242 and the corresponding side scraping rod 238 above it for scraping. Subsequently, the side scraping rod 238 and the bottom scraping rod 242 can respectively scrape and mix the chemical raw materials attached to the inner wall of the reaction tank 1 and the semi-circular bottom plate 11, thereby improving the mixing quality and mixing efficiency of the chemical raw materials.

[0043] Please refer to Figure 1 , Figure 2 and Figure 5 The upper end of the tank cover 2 is provided with a driving assembly for driving the central shaft 22 to rotate synchronously with the stirring assembly. The driving assembly includes a rotating gear 251 installed after the upper end of the central shaft 22 rotates through the tank cover 2. The rear side of the rotating gear 251 is meshed with a driving gear 252 rotatably installed on the upper end of the tank cover 2. The upper end of the driving gear 252 is connected to the output shaft of the motor 253. The motor 253 is installed on the upper end of the tank cover 2 through a support. The upper end of the threaded column 228 passes through the central shaft 22 and is provided with a rectangular groove. The upper end of the rotating gear 251 is installed with a column 254, and a moving plate is slidably installed on the column 254. The lower end of the moving plate is installed with a rectangular rod 256 that is plugged into the rectangular groove.

[0044] After the above-mentioned several stirring rods 222 rotate synchronously to the corresponding annular inclined grooves 223, the movable plate can be moved downward along the column 254, so that the rectangular rod 256 at the lower end of the movable plate is inserted into the rectangular groove at the upper end of the threaded column 228, so as to limit the threaded column 228 circumferentially, and also limit the uppermost mounting ring 221 up and down, effectively preventing the threaded column 228 from rotating and reducing the stability between the stirring assembly and the reaction tank 1, and ensuring that the threaded column 228 can rotate synchronously and stably with the central axis 22.

[0045] After the placement of the stirring unit 21 and the adjustment of the stirring assembly are completed, the existing feeding equipment can put the chemical raw materials to be mixed into the reaction tank 1 through the pipeline and the feed port. Finally, the driving gear 252 can be driven to rotate by the motor 253, and the rotating gear 251 and the central shaft 22 can rotate synchronously. The central shaft 22 drives the stirring components evenly arranged up and down to rotate synchronously, so as to stir and mix the chemical raw materials inside the reaction tank 1. After the mixing of the chemical raw materials is completed, the left and right semicircular bottom plates 11 can be controlled to open by the existing electric control equipment to complete the discharge of the mixed chemical raw materials.
