Description

Technical Field

[0001] This invention relates to the field of aluminum sulfate preparation technology, and more specifically to a production apparatus for polyaluminum sulfate. Background Technology

[0002] Aluminum polysulfate, as an important inorganic polymeric flocculant, is widely used in water treatment, papermaking, and chemical industries. Its high-efficiency flocculation performance is of great significance for industrial production and environmental protection. In the production of liquid aluminum polysulfate, the core process involves mixing aluminum hydroxide slurry, water, and concentrated sulfuric acid in a specific ratio and then carrying out a chemical reaction. Traditional production equipment often adopts a single-batch, intermittent reaction mode, meaning that after one feeding, reaction, and discharge cycle, the next batch of production begins. This production method has significant drawbacks: Firstly, in single-batch production, the raw material addition, reaction, and discharge stages are independent of each other. Each stage requires waiting for the preceding stage to finish, resulting in significant waiting time in the production process. In particular, the reaction vessel needs to be refilled after unloading and wait for the reaction to restart, leading to low production efficiency and difficulty in meeting the needs of large-scale production. Secondly, traditional equipment cannot flexibly adjust the stirring speed according to actual production needs such as raw material ratios and reaction progress, easily causing problems such as incomplete reaction or over-stirring, affecting the stability of product quality. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a production apparatus for polyaluminum sulfate. Through the alternating operation of the dual chambers of the reaction cylinder, seamless integration of raw material addition, reaction, and discharge processes is achieved. When the mixture on one side reaches a certain volume, the reaction cylinder rotates 180°, the positions of the two sides are interchanged, and liquid begins to enter the empty side. The stirring mechanism continuously stirs both sides to accelerate the reaction, eliminating the waiting time of traditional single-batch production and making the production process continuous. The stirring mechanism can be adjusted to achieve fast or slow stirring by adjusting the lifting rod, and the switching speed of the two sides of the reaction cylinder also changes accordingly. This, combined with the feeding speed of the feeding mechanism, allows for flexible adjustment of the production speed according to actual production needs, enabling switching between fast and slow production modes and improving the applicability and production flexibility of the apparatus.

[0013] The beneficial effects of this invention are:

[0014] 1. This invention achieves seamless connection between raw material addition, reaction, and discharge processes through the alternating operation of the dual chambers of the reaction cylinder. When the mixture on one side reaches a certain amount, the reaction cylinder rotates 180°, the positions of the two sides are interchanged, and the empty side begins to receive liquid. The stirring mechanism continuously stirs both sides to accelerate the reaction, eliminating the waiting time of traditional single-batch production, making the production process continuous, greatly improving production efficiency, and meeting the needs of large-scale industrial production.

[0015] 2. The lifting rod in the device can synchronously adjust the working speed of the stirring mechanism and the reaction cylinder drive mechanism. By adjusting the lifting rod, the stirring mechanism can achieve fast or slow stirring.

[0016] 3. The sealing components installed in the moving discharge pipes on both sides of the reaction cylinder can adaptively open or seal when coupled or decoupled from the stationary discharge pipe. Under normal conditions, the sealing plate blocks the through hole, and no liquid is discharged from the moving discharge pipe. When the moving discharge pipe moves to the stationary discharge pipe, the contact rod is pushed to open the through hole, and the liquid after the reaction flows into the stationary discharge pipe and is discharged. Discharge can be achieved without manual operation, ensuring the smoothness and sealing of the discharge process, and improving the automation and reliability of the device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0027] refer to Figure 1 and Figure 2The diagram illustrates a specific embodiment of the production apparatus for polyaluminum sulfate according to the present invention. It includes a base 1, a reaction cylinder 2, a feeding mechanism 3, a stirring mechanism 4, and a reaction cylinder drive mechanism 5. The reaction cylinder 2 is rotatably mounted on the upper end of the base 1. A partition 202 is fixedly installed in the middle of the reaction cylinder 2. The feeding mechanism 3 can inject reaction raw materials into one side of the reaction cylinder 2 according to a preset ratio. The stirring mechanism 4 is installed on the upper end of the partition 202. The reaction cylinder drive mechanism 5 is installed inside the base 1. A drive shaft 101 and a lifting rod 102 are mounted on the base 1. The drive shaft 101 can synchronously drive the stirring mechanism 4 and the reaction cylinder drive mechanism 5. The lifting rod 102 can synchronously adjust the working speed of the stirring mechanism 4 and the reaction cylinder drive mechanism 5. The stirring mechanism 4 can synchronously stir both sides of the partition 202. The reaction cylinder drive mechanism 5 can intermittently drive the reaction cylinder 2 to rotate 180°. In operation, aluminum hydroxide slurry, water, and concentrated sulfuric acid are mixed and continuously injected into one side of the partition 202 inside the reaction cylinder 2. Once the mixture on one side of the reaction cylinder 2 reaches a certain volume, the reaction cylinder 2 rotates 180°, swapping the positions of the two sides. Liquid begins to enter from the empty side. During this process, the stirring mechanism 4 continuously stirs both sides of the reaction cylinder 2 to accelerate the reaction. A movable discharge pipe 203 is symmetrically fixedly installed on both sides of the reaction cylinder 2, and a stationary discharge pipe 103 is fixedly installed on one side of the base 1. A sealing component is installed inside the movable discharge pipe 203. This sealing component is used to adaptively open or seal when the movable discharge pipe 203 is coupled or decoupled from the stationary discharge pipe 103. When the side of the reaction cylinder 2 containing the reaction liquid moves to the stationary discharge pipe 103, the reacted liquid can be discharged for subsequent processing. Through the above structural design, this invention enables continuous production through the alternating operation of the dual chambers of the reaction cylinder 2, eliminating the waiting time of traditional single-batch production, and seamlessly connecting the raw material addition, reaction, and discharge processes, greatly improving production efficiency. Furthermore, since the lifting rod 102 can synchronously adjust the working speed of the stirring mechanism 4 and the reaction cylinder drive mechanism 5, the feeding speed of the feeding mechanism 3 can be adjusted according to production needs. The stirring speed of the stirring mechanism 4 and the switching speed of the two sides of the reaction cylinder 2 can be adjusted by adjusting the lifting rod 102, thereby adjusting the production speed.

[0028] like Figure 3As shown, the stirring mechanism 4 includes a fixed frame 401, two stirring rods 402, and a rotating shaft 407. The fixed frame 401 is fixedly installed on the upper end of the partition 202. The upper ends of the two stirring rods 402 are rotatably installed on both ends of the fixed frame 401. Gear 1 403 and gear 2 404 are fixedly installed on the upper ends of the stirring rods 402. Gear 3 405 and gear 406 are symmetrically rotatably installed on both ends of the fixed frame 401. Each gear 3 405 meshes with the corresponding gear 1 403. Gear 406 meshes with corresponding gear 2 404. A cover 201 is fixedly installed on the upper end of the reaction cylinder 2. A rotating shaft 407 is rotatably installed in the middle of the cover 201. The upper end of the rotating shaft 407 is connected to the drive shaft 101 via a belt and pulley. Gear 5 408 is slidably installed on the lower end of the rotating shaft 407. Gear 6 409 is fixedly installed on the upper end of gear 5 408. Gear 5 408 meshes with gear 3 405, and gear 6 409 meshes with gear 406. The diameter of gear 1 403 is smaller than the diameter of gear 2 404, and the diameter of gear 5 408 is larger than the diameter of gear 6 409. The distance between each gear 1 403 and its corresponding gear 2 404 is greater than the distance between gear 5 408 and gear 6 409. The upper end of gear 6 409 is slidably connected to the upper end of the lifting rod 102. Rotating the shaft 407 can drive gears 408 and 409 to rotate synchronously. When gear 408 moves down and meshes with gear 3 405, gear 409 does not contact gear 406. Through the transmission of each gear, the stirring rod 402 can be driven to rotate quickly to achieve rapid stirring. When the lifting rod 102 drives gear 409 to move up, gear 409 meshes with gear 406, and gear 408 does not contact gear 3 405. Through the transmission of each gear, the stirring rod 402 can be driven to rotate slowly to achieve slow stirring. The above structure not only enables the switching of stirring speed, but also ensures that the driving of the stirring rod 402 does not interfere with the rotation of the reaction cylinder 2.

[0029] like Figure 4As shown, the feeding mechanism 3 includes a first material cylinder 301, a second material cylinder 302, a third material cylinder 303, a first connecting pipe 304, a stirring cylinder 305, and a second connecting pipe 306. The first material cylinder 301, the second material cylinder 302, and the third material cylinder 303 are all fixedly installed above the reaction cylinder 2. The first material cylinder 301, the second material cylinder 302, and the third material cylinder 303 are respectively used to store aluminum hydroxide slurry, water, and concentrated sulfuric acid. The stirring cylinder 305 is fixedly installed below the first material cylinder 301 and the second material cylinder 302. The first connecting pipe 304 connects to the lower end of the first material cylinder 301, the lower end of the second material cylinder 302, and the upper part of the stirring cylinder 305. The two connecting pipes 306 are connected to the lower end of the three material cylinders 303, the bottom of the stirring cylinder 305, and the lower part of the cylinder cover 201. A stirring roller is rotatably installed inside the stirring cylinder 305. The lower end of the stirring roller is connected to the drive shaft 101 through the cooperation of a belt and a pulley. After aluminum hydroxide slurry of a specific concentration and water are mixed in a certain proportion, it enters the stirring cylinder 305 through the first connecting pipe 304 and is mixed in the stirring cylinder 305. Then, the aluminum hydroxide slurry with the adjusted concentration is mixed with concentrated sulfuric acid through the second connecting pipe 306 and injected into one side of the reaction cylinder 2 from the top, thus completing the feeding. A valve 307 is fixedly installed at the connection between the first material cylinder 301 and the second material cylinder 302 and the first connecting pipe 304, for adjusting the feeding ratio of aluminum hydroxide slurry and water. A valve 308 is fixedly installed at the connection between the third material cylinder 303 and the second connecting pipe 306, for adjusting the feeding ratio of concentrated sulfuric acid. A valve 309 is fixedly installed at the lower end of the second connecting pipe 306, for controlling the feeding speed.

[0030] like Figure 5 and Figure 6As shown, the reaction cylinder drive mechanism 5 includes a second rotating shaft 501, a turntable 502, two telescopic rod assemblies 504, and a semi-ring plate 505. The second rotating shaft 501 passes through the upper end of the base 1 and is rotatably connected to the base 1. The turntable 502 is fixedly installed on the upper end of the second rotating shaft 501. A single tooth 503 is fixedly installed on the edge of the turntable 502. The semi-ring plate 505 is fixedly installed on the upper end of the base 1 and is coaxial with the turntable 502. The two telescopic rod assemblies 504 are symmetrically installed on the lower end of the reaction cylinder 2, and both telescopic rod assemblies 504 are located in the gap between the turntable 502 and the semi-ring plate 505. Telescopic rods 5042 are elastically installed on the telescopic rod assemblies 504. The telescopic rod assembly 504 includes a housing 5041 with a through groove inside. The telescopic rod 5042 is slidably installed in the through groove. Grooves are symmetrically arranged on both sides of the through groove, and guide rods 5044 are fixedly installed in the grooves. Protrusions 5043 are symmetrically arranged on both sides of the telescopic rod 5042, each protrusion 5043 being disposed in a corresponding groove, and each guide rod 5044 passing through a corresponding protrusion 5043. A spring 5045 is sleeved on each guide rod 5044. Normally, one end of the telescopic rod 5042 passes through the outside of the housing 5041 (e.g., ...). Figure 5 As shown at point A in the diagram, as the reaction cylinder 2 rotates, when the telescopic rod 5042 contacts the semi-annular plate 505, the semi-annular plate 505 pushes one end of the telescopic rod 5042, causing it to retract until the other end of the telescopic rod 5042 passes through the inner side of the outer casing 5041 (as shown in the diagram). Figure 5 As shown at point B, the rotating disk 502 is driven to rotate by the rotating shaft 501. The single tooth 503 contacts the telescopic rod 5042 at point B and drives the reaction cylinder 2 to rotate. When the telescopic rod 5042 at point B rotates to point A, the telescopic rod 5042 disengages from the semi-ring plate 505 and resets. The single tooth 503 disengages from the telescopic rod 5042, and the reaction cylinder 2 stops rotating. When the rotating disk 502 rotates 180°, it re-contacts the other telescopic rod 5042 and drives the reaction cylinder 2 to rotate again, thus realizing the intermittent rotation of the reaction cylinder 2 by 180°.

[0031] like Figure 7As shown, the reaction cylinder drive mechanism 5 also includes a rotating shaft 3 506, which is rotatably mounted inside the base 1. Gear 7 507 and gear 8 508 are fixedly mounted on the upper end of the rotating shaft 3 506. The lower end of the rotating shaft 3 506 is connected to the drive shaft 101 through the cooperation of a belt and a pulley. Gear 9 509 is slidably mounted on the lower end of the rotating shaft 2 501. Gear 10 510 is fixedly mounted on the lower end of the gear 9 509. Gear 8 508 and gear 10 510 cooperate, and gear 7 507 and gear 9 509 cooperate. The diameter of gear 7 507 is smaller than the diameter of gear 8 508, and the diameter of gear 9 509 is larger than the diameter of gear 10 510. The distance between gear 7 507 and gear 8 508 is greater than the distance between gear 9 509 and gear 10 510. The lower end of gear 10 510 is slidably connected to the lower end of the lifting rod 102. Driven by drive shaft 101, rotating shaft 506 rotates. When lifting rod 102 drives gear 510 to move downward, gear 510 meshes with gear 508, causing rotating shaft 501 to rotate rapidly. The switching speed between the two sides of reaction cylinder 2 is relatively fast. Combined with the rapid feeding of feeding mechanism 3 and the rapid stirring of stirring mechanism 4, the device enters a fast production mode. When lifting rod 102 drives gear 510 to move upward, gear 509 meshes with gear 507, rotating shaft 501 rotates slowly. The switching speed between the two sides of reaction cylinder 2 is relatively slow. Combined with the slow feeding of feeding mechanism 3 and the slow stirring of stirring mechanism 4, the device enters a slow production mode. The production mode is adjusted according to actual production needs.

[0032] like Figure 8As shown, the sealing assembly includes a fixing plate 2031, a contact rod 2032, a sealing plate 2033, a fixing ring 2034, and a spring 2035. The fixing plate 2031 is fixedly installed inside the moving discharge pipe 203. The contact rod 2032 passes through the fixing plate 2031. The fixing plate 2031 has multiple through holes arranged in a circular array around the contact rod 2032. The sealing plate 2033 is fixedly installed at the upper end of the contact rod 2032, and the fixing ring 2034 is fixedly installed at the lower end of the contact rod 2032. At the end, the spring 2035 is sleeved on the contact rod 2032, and the spring 2035 is disposed between the fixing plate 2031 and the fixing ring 2034. A drain plate 1031 is fixedly installed inside the static discharge pipe 103. The drain plate 1031 is provided with multiple drain holes. A protrusion 1032 is fixedly installed at the upper end of the drain plate 1031. The upper end of the protrusion 1032 passes through the upper end of the static discharge pipe 103. The lower end of the contact rod 2032 and the upper end of the protrusion 1032 are both hemispherical. Under normal conditions, the sealing plate 2033 is attached to the fixing plate 2031, the through hole is blocked, and the moving discharge pipe 203 does not discharge liquid. When the moving discharge pipe 203 moves to the stationary discharge pipe 103, the contact rod 2032 contacts the protrusion 1032 and is pushed upward, the through hole opens, the reacted liquid flows into the stationary discharge pipe 103, and is discharged from the lower end of the stationary discharge pipe 103 through the leakage hole, thus achieving adaptive discharge.
