Description

Technical Field

[0001] This utility model relates to the field of dissolving equipment technology, and in particular to a dissolving device for polyaluminum chloride reaction. Background Technology

[0002] A polyaluminum chloride (PAC) reaction dissolution device is a specialized unit designed to efficiently convert solid PAC into a homogeneous liquid solution. It primarily accelerates the dissolution process of PAC in water through stirring and heating, ensuring complete dissolution and guaranteeing the stable and efficient conduct of subsequent chemical reactions. This dissolution device plays a crucial role in numerous industrial fields such as water treatment, papermaking, and printing and dyeing. It precisely controls the solution concentration, effectively improving the performance of PAC in various production processes and meeting the stringent requirements of different production processes for reagent solutions.

[0003] When the dissolving device for polyaluminum chloride (PAC) is in operation, solid PAC is first added to the dissolving tank along with an appropriate amount of water. The stirring system is then activated, and the impeller rotates at high speed. This ensures thorough contact and mixing between the PAC and water, breaking up their original aggregated state and increasing the contact area. Simultaneously, the mechanical force accelerates the diffusion of molecules. If a heating system is included, the solution temperature will be raised, further accelerating molecular thermal motion and reducing the dissolution time of the PAC. Under the synergistic effect of these multiple processes, the solid PAC gradually dissolves in the water, forming a uniformly dispersed liquid PAC solution with a concentration meeting the requirements for subsequent chemical reactions.

[0004] However, in existing technologies, some polyaluminum chloride (PAC) reaction dissolving devices suffer from inconvenient feed pipe replacement. Due to the inherent chemical properties of PAC, the feed pipe is highly susceptible to corrosion and wear during continuous feeding, significantly shortening its lifespan and necessitating frequent replacement. Furthermore, some dissolving devices have design flaws, with extremely complex connections between the feed pipe and the main body, involving numerous cumbersome installation and disassembly steps. This not only requires highly skilled technicians to expend considerable time and effort, but also poses a risk of accidental damage to other components during replacement, affecting the overall operation of the dissolving device, leading to reduced production efficiency, increased maintenance costs, and considerable disruption to the production and operation of related enterprises. Therefore, this paper proposes a PAC reaction dissolving device to address these issues. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a dissolving device for polyaluminum chloride reaction, comprising a tank 1, a top cover 2 fixedly connected to the top of the tank 1, and a fixing ring 3 fixedly connected to the top of the top cover 2. The presence of the fixing ring 3 allows subsequent installed components such as shrinkage columns 4 and telescopic columns 6 to be precisely positioned and work together, ensuring the compact and stable structure of the entire device and preventing malfunctions due to loose components during operation, thus enhancing the reliability and safety of the device. Multiple shrinkage columns 4 are fixedly connected to the inner wall of the fixing ring 3. When subjected to external pressure, an internal damping device consumes part of the impact force, causing the shrinkage columns 4 to slowly retract. The multiple shrinkage columns 4 are evenly distributed on the inner wall of the fixing ring 3, and springs 5 ​​are respectively sleeved on the outside of each of the multiple shrinkage columns 4. When the impact force disappears, the springs 5 ​​release elastic potential energy, pushing the lower pressure ring 7 to reset, thereby driving other components connected to the lower pressure ring 7 back to their initial positions.

[0033] Multiple telescopic columns 6 are fixedly connected to the top of the fixed ring 3. These telescopic columns 6 function when the height of the feed pipe 14 needs to be finely adjusted to adapt to different working conditions or material characteristics. A downward pressure ring 7 is fixedly connected to the top of each telescopic column 6. When the downward pressure ring 7 rises or falls with the telescopic columns 6, it drives the connected push block 8 to move synchronously. Multiple push blocks 8 are fixedly connected to the bottom of the downward pressure ring 7. When the telescopic columns 6 drive the downward pressure ring 7 to descend, the push block 8 moves downward accordingly, and its wedge-shaped inclined surface contacts the moving block 9. As the downward pressure ring 7 continues to descend, the inclined surface of the push block 8 converts the vertically downward force into a horizontal component force, pushing the moving block 9 to slide outward.

[0034] Multiple push blocks 8 have sliding blocks 9 slidably connected to their bottom ends on opposite sides. When the push blocks 8 move downwards and push the sliding blocks 9 through the inclined plane, the sliding blocks 9 slide outwards within the track against friction. The sliding design of the sliding blocks 9 allows the entire feed pipe fixing system to be flexibly adjusted according to the movement state of the pressure ring 7. The bottom ends of the multiple sliding blocks 9 are fixedly connected to fixing strips 10. The fixing strips 10 mainly serve to connect the sliding blocks 9 to the connecting ring 11, transmitting the horizontal sliding motion of the sliding blocks 9 to the connecting ring 11.

[0035] Multiple fixing bars 10 are fixedly connected to their bottom ends with connecting rings 11. When the moving block 9 drives the fixing bars 10 to slide outward, the connecting rings 11 move outward accordingly, thereby driving the connected locking blocks 12 to move. The function of the connecting rings 11 is to concentrate the movement of the fixing bars 10 to the locking blocks 12. Locking blocks 12 are fixedly connected to adjacent sides of the multiple connecting rings 11. When the connecting rings 11 move outward, the locking blocks 12 move accordingly. The multiple locking blocks 12 work together to tightly clamp the feed pipe 14. A chassis 13 is fixedly connected to the outside of the multiple locking blocks 12. The feed pipe 14 is fixedly connected to the inner wall of the multiple chassis 13. A grinding assembly for grinding is fixedly connected to the top of the feed pipe 14.

[0036] Reference Figures 2 to 4 The grinding assembly includes a housing 15, the inner wall of which is fixedly connected to the outer top of the feed pipe 14. Multiple large rotating shafts 16 are rotatably connected to the inner top of the housing 15. When the motor starts, the large rotating shafts 16 rotate at high speed. The surface of the large rotating shafts 16 is typically provided with multiple large grinding teeth or protrusions. During rotation, these grinding teeth are used to initially coarsely crush the larger pieces of polyaluminum chloride raw material entering from the feed pipe 14. Multiple medium-sized rotating shafts 17 are rotatably connected to the middle section of the housing 15. When the raw material, initially crushed by the large rotating shafts 16, falls into the area of ​​the medium rotating shafts 17, the medium rotating shafts 17 rotate at high speed, using their surface grinding structures to further refine the particles.

[0037] Multiple medium-sized rotating shafts 17 work together to thoroughly grind the raw material as it falls. Multiple small rotating shafts 18 are rotatably connected to the bottom of the outer casing 15. When the raw material, after passing through the first two stages of grinding, reaches the position of the small rotating shaft 18, the small rotating shaft 18 rotates at high speed, using its fine grinding surface to perform a final fine grinding of the raw material, grinding the particles to an extremely fine degree. Multiple small rotating shafts 18 are evenly distributed inside the bottom of the outer casing 15, enabling comprehensive and meticulous grinding of the falling raw material, ensuring that the raw material particles reach the optimal fineness, providing a strong guarantee for efficient dissolution in the tank 1. A protective cover 19 is fixedly connected to the top of the outer casing 15. This further enhances the protection of the high-speed rotating components inside the grinding assembly, preventing foreign objects from falling in from above, while also reducing dust emissions during grinding, improving the working environment, and protecting the health of operators.

[0038] Reference Figures 1 to 3 Multiple connecting strips 20 are fixedly connected to the exterior of the outer casing 15 to ensure that the force borne by the outer casing 15 during operation can be effectively transmitted to the connecting rods 21 through the connecting strips 20, thereby achieving coordinated operation of the entire grinding assembly and other parts. Connecting rods 21 are fixedly connected to the opposite sides of the multiple connecting strips 20. The force transmitted from the outer casing 15 by the connecting strips 20 is transmitted to other connected structures, achieving force balance and coordinated movement among the components. A base plate 23 is fixedly connected to the bottom end of the top cover 2, providing a stable mounting platform for the upper support rod 22, the lower support rod 24, and the material outlet 25.

[0039] Multiple support rods 22 are fixedly connected to the top of the base plate 23. Utilizing their rigid support, they provide auxiliary support to the top cover 2 from above. During operation, especially when the top cover 2 is subjected to pressure from the grinding assembly or other components, the support rods 22 can share some of the pressure, transferring the force to the base plate 23 and distributing it throughout the entire structure. Multiple support rods 24 are fixedly connected to the bottom of the base plate 23. When the entire device is subjected to vibration or other external forces, the support rods 24 can effectively transfer the reaction force from below to the base plate 23, maintaining the stability of the base plate 23 and the top cover 2 together with the support rods 22. A material outlet 25 is fixedly connected to the bottom of the base plate 23. The material outlet 25 is designed to be located at the bottom of the base plate 23, facilitating the natural fall of materials under gravity, reducing the need for additional conveying power, and improving production efficiency.

[0040] Multiple connecting rings 11 are fixedly connected at opposite ends to multiple contraction columns 4 at adjacent ends. When the contraction columns 4 are subjected to external force and expand or contract, the connecting rings 11 can drive the connected components such as the locking blocks 12 to move synchronously. The external parts of the multiple connecting rings 11 are slidably connected to the inside of the fixed ring 3. When the contraction columns 4 drive the connecting rings 11 to move, the connecting rings 11 can slide in a predetermined direction within the internal track of the fixed ring 3, thereby ensuring the accuracy and stability of the movement of the connected components such as the locking blocks 12. The external parts of the multiple moving blocks 9 are slidably connected to the inner wall of the top of the fixed ring 3, and the moving blocks 9 can slide freely within the groove. The moving blocks 9 are connected to components such as the push block 8 and the fixing strip 10. Their working principle is that when the push block 8 moves downward under the action of the pressing ring 7 and pushes the moving blocks 9, the moving blocks 9 slide horizontally within the groove on the inner wall of the top of the fixed ring 3.

[0041] Multiple springs 5 ​​are externally slidably connected to the inside of the fixed ring 3. When the contraction column 4 retracts under impact, the pressure ring 7 descends accordingly, compressing the springs 5, which store elastic potential energy. When the impact disappears, the springs 5 ​​release their elastic potential energy, pushing the pressure ring 7 to reset. Multiple locking blocks 12 are externally slidably connected to the inside of the fixed ring 3 on opposite sides. When the connecting ring 11 moves under the drive of the contraction column 4, the locking blocks 12 slide within the track inside the fixed ring 3, thereby achieving the clamping or releasing operation of the feed pipe 14. The chassis 13 is externally fixedly connected to the inner wall of the fixed ring 3. The weight from the locking blocks 12 and the feed pipe 14 is evenly transferred to the entire device structure through the fixed ring 3. The fixed ring 3 provides support and fixation for the chassis 13, ensuring that the chassis 13 does not shift or shake during device operation.

[0042] Working principle: When the feed pipe 14 needs to be replaced in the dissolving device for polyaluminum chloride reaction, the lower pressure ring 7 drives the telescopic column 6 downward. The push block 8, along with the lower pressure ring 7, pushes the moving block 9 to slide outward on the inner wall of the top of the fixed ring 3. The moving block 9 drives the fixed strip 10 and the connecting ring 11 to move outward simultaneously. The connecting ring 11 pulls the contraction column 4 and compresses the spring 5, while simultaneously causing the locking block 12 to disengage from the inner wall of the fixed ring 3. This allows the chassis 13 and the feed pipe 14 connected to the locking block 12 to be detached from the fixed ring 3. This achieves the effect of convenient and quick replacement of the feed pipe 14, facilitating equipment maintenance and adapting to different working conditions.

[0043] When the damp, clump-forming solid polyaluminum chloride enters the outer casing 15, the motor drives the large rotating shaft 16 to rotate. The large rotating shaft 16 drives the grinding components on it to initially crush the material, breaking down large pieces. After the initial processing, the material falls under gravity, and the medium rotating shaft 17, driven by the motor, rotates, driving the corresponding grinding components to further grind the material, making the particles even smaller. Next, the small rotating shaft 18, driven by the motor, rotates to finely grind the material, completely pulverizing it into fine particles. These fine particles enter the subsequent processes through the feed pipe 14. This effectively prevents the solid polyaluminum chloride from clogging the feeding mechanism due to moisture and clumping, ensuring smooth feeding and stable equipment operation.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
