Description

Technical Field

[0001] This utility model relates to the technical field of chemical production equipment, and in particular to a reaction vessel for pre-excitation of precursors of silicon-aluminum industrial solid waste. Background Technology

[0002] A reaction vessel for pre-activation of precursors for silicoaluminous industrial solid waste is a specialized piece of equipment that uses a feed pipe, stirring shaft, and quantitative feeding components to collaboratively complete material conveying, stirring reaction, and quantitative output. It pre-treats silicoaluminous industrial solid waste such as fly ash and coal gangue to change their physicochemical properties for resource recycling and building material production. It features precise material conveying control, uniform and efficient reaction, strong temperature regulation adaptability, and the ability to achieve harmless, reduced, and resource-based utilization of solid waste.

[0003] Reactors used for pre-activation of precursors for silicon-aluminum industrial solid waste typically consist of a main structure (including vessel body and vessel cover), stirring components (including stirrer, stirring shaft, and drive device), heating / cooling, inlet and outlet pipelines, sealing, control and safety devices, auxiliary devices, and special functional components set according to process requirements. These components are designed to balance corrosion resistance, mixing efficiency, and temperature and pressure control, ensuring that the solid waste and activator react fully.

[0004] The reactor used for pre-activation of precursors from silicon-aluminum industrial solid waste suffers from poor pipe sealing and reactor sealing, leading to easy leakage of media. This can easily cause accidents such as fires, poisoning, and pollution, while also reducing production efficiency, increasing equipment maintenance costs, and posing safety risks. Media leakage can cause an imbalance in the ratio of solid waste to activator, affecting the sufficiency and uniformity of the reaction, reducing the pre-activation effect, and consequently affecting the quality of the final product. In addition, the leaked corrosive media can corrode equipment and plant buildings, shortening equipment lifespan and increasing maintenance costs. Furthermore, if the leaked substance is toxic, flammable, or explosive, it can threaten the personal safety of operators and even cause major safety accidents such as fires and explosions. Moreover, the material waste caused by sealing failure increases production costs and leads to a decline in economic benefits. At the same time, material leakage can also pollute the surrounding environment, violating the concept of green production. Therefore, a reactor for pre-activation of precursors from silicon-aluminum industrial solid waste is proposed to solve the above problems. Utility Model Content

[0007] This utility model has the following beneficial effects: 1. In this invention, the driving gear meshes with the driven gear and rotates to drive the crank connecting rod. The crank connecting rod and the arc-shaped clamp are connected and squeezed by the rotation of the gear, moving along the arc-shaped groove in the driven gear. Through gear transmission, the power of the electric motor is converted into the centripetal motion of the arc-shaped clamp. This allows for uniform and stable squeezing and fixing of the feed pipe after it is connected to the reactor lid. This fixing method effectively avoids loosening, displacement, or even detachment of the feed pipe during material transportation due to pressure fluctuations or mechanical vibrations, ensuring stable material delivery to the reactor, preventing raw material leakage that could lead to waste and environmental pollution, and also preventing interruption of the reaction process due to pipe detachment, thus improving production continuity and efficiency. 2. In this utility model, the sliding connection between the three-way pipe and the piston allows for precise control of material extraction and discharge through piston movement. The reciprocating sliding of the piston can accurately adjust the amount of material entering the component, avoiding the impact of excessive or insufficient material feeding on subsequent production processes. The transmission structure composed of the connecting rod, connecting plate, clamping plate, and cylinder provides reliable power for the turning of the three-way pipe. The extension and retraction of the cylinder drives the clamping plate to move, which in turn enables the three-way pipe to rotate flexibly through the connecting plate and connecting rod. This design allows the three-way pipe to quickly switch material flow direction for efficient conversion. The water tank can temporarily store a fixed amount of material, which, in conjunction with the operation of the compression pump, achieves stable material output. Attached Figure Description

[0013] 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.

[0014] Reference Figures 1 to 3 This utility model provides an embodiment of a reactor for pre-excitation of precursors for silicon-aluminum industrial solid waste, including a feed pipe 9. A driven gear 17 is slidably connected to the bottom of the feed pipe 9. The driven gear 17 can rotate flexibly around the bottom of the feed pipe 9, providing a basis for the operation of the subsequent pipe fixing mechanism. Multiple crank connecting rods 18 are slidably connected inside the driven gear 17. When the driven gear 17 rotates, the crank connecting rods 18 slide along the internal groove of the gear. Arc-shaped clamps 20 are fixedly connected to the inner side of each of the multiple crank connecting rods 18. The movement of the crank connecting rods 18 drives the arc-shaped clamps 20 to move into the gear, thereby realizing the squeezing and fixing of the pipe and ensuring the stability of the pipe connection.

[0015] Multiple fixed plates 19 are fixedly connected to the bottom of multiple crank connecting rods 18. The fixed plates 19 support and fix the crank connecting rods 18, preventing them from shifting or shaking during operation and ensuring the reliability of the pipeline fixation. A chassis 31 is slidably connected to the outer side of the multiple fixed plates 19. The chassis 31 provides a sliding track for the fixed plates 19, ensuring the stability and accuracy of the fixed plates 19 during operation. A drive gear 16 is slidably connected to the top of the chassis 31. The drive gear 16 can slide freely on the chassis 31, ensuring good meshing with the driven gear 17 and achieving efficient power transmission. A gear shaft 15 is rotatably connected inside the drive gear 16. The rotation of the gear shaft 15 drives the drive gear 16 to rotate synchronously, providing power support for the entire transmission device. The bottom of the feed pipe 9 is fixedly connected to the top of the reactor cover 7, making the feed pipe 9 and the reactor cover 7 form a whole, ensuring that the raw materials can smoothly enter the reactor and avoid leakage.

[0016] The bottom of the vessel lid 7 is slidably connected to the vessel body 3. This connection method ensures a tight fit between the lid 7 and the vessel body 3, while also facilitating disassembly and installation, thus improving equipment maintenance efficiency. The bottom of the vessel body 3 is slidably connected to a feed pipe 21, which serves as the outlet for the reaction products, allowing the reacted materials to be smoothly discharged from the reactor, preparing for subsequent processing steps. The bottom of the feed pipe 21 is fixedly connected to a conduit 22, providing a channel for material transport. The other end of the conduit 22 is slidably connected to a connecting pipe 23, which connects the conduit 22 to a quantitative feeding assembly, enabling continuous material transport and ensuring the continuity of the production process. The bottom of the connecting pipe 23 is fixedly connected to a quantitative feeding assembly. The quantitative feeding assembly can precisely control the amount of material fed, ensuring the stability and consistency of product quality.

[0017] Reference Figure 1 , Figure 2 , Figure 4The quantitative feeding component includes a three-way valve 24, which can flexibly switch the material flow direction to achieve precise distribution of materials between different pipelines, ensuring that reaction products can be transported along a set path. A piston 25 is slidably connected to the right side of the three-way valve 24. The piston 25 precisely controls the extraction and discharge of liquid by reciprocating within the three-way valve 24, thereby realizing the core function of quantitative feeding. The front side of the three-way valve 24 is slidably connected to the rear side of the connecting rod 26. The connecting rod 26 can effectively transmit the linear motion of the piston 25, providing a power transmission basis for the action of subsequent components. The other end of the connecting rod 26 is rotatably connected to a connecting plate 27. The connecting plate 27 converts the linear motion of the connecting rod 26 into arc motion, providing a flexible movement mode for the clamping plate 28. The other end of the connecting plate 27 is rotatably connected to a clamping plate 28. Under the drive of the connecting plate 27, the clamping plate 28 realizes the control of the three-way valve. Precise control of the rotation angle of the pipe 24 changes the material conveying direction. The other end of the clamp 28 is fixedly connected to a cylinder 29, which serves as a power source and precisely drives the clamp 28 through telescopic movement, ensuring the stability and reliability of the rotation operation of the three-way pipe 24. The left side of the three-way pipe 24 is slidably connected to the right side of the pipe 32. The pipe 32 receives the material distributed by the three-way pipe 24 and will stably convey it to the next stage. The left side of the pipe 32 is connected to a sleeve 33, which provides stable support and protection for the pipe 32 to prevent leakage or damage due to external forces during material conveying. The left side of the sleeve 33 is connected to a water tank 34, which is used to temporarily store the material after quantitative measurement, providing buffer and storage space for subsequent processing. The top of the water tank 34 is fixedly connected to a compression pump 30, which squeezes the material in the water tank 34 at a set flow rate, ultimately achieving the purpose of precise quantitative feeding.

[0018] The other end of the feed pipe 9 is fixedly connected to a water pump 10. The water pump 10 can generate strong suction to quickly and stably transport the silicon-aluminum industrial solid waste precursor raw material in the raw material tank 11 to the reactor through the straight pipe 35 and the feed pipe 9, ensuring the raw material supply efficiency. The other end of the water pump 10 is fixedly connected to a straight pipe 35, which provides a straight channel for raw material transportation, reduces the resistance of the raw material during transportation, and allows the raw material to enter the water pump 10 at a stable flow rate. The bottom of the straight pipe 35 is slidably connected to the raw material tank 11. This connection method facilitates quick replacement of the raw material tank 11 while ensuring a tight connection to prevent raw material leakage.

[0019] A base plate 31 is slidably connected to the bottom of the feed pipe 9. The base plate 31 provides stable support for the feed pipe 9 and allows the feed pipe 9 to be flexibly adjusted in position for easy and precise docking with the feed port on the lid 7. A driven gear 17 is rotatably connected to the top of the base plate 31. The driven gear 17 can rotate flexibly around the base plate 31, providing a power transmission basis for driving the arc clamp 20 to fix the pipe. The top of the fixing plate 19 is slidably connected to the bottom of the driven gear 17. The fixing plate 19 restricts the movement trajectory of the crank connecting rod 18, ensuring that the arc clamp 20 can be stably pushed in a predetermined direction when the driven gear 17 rotates. The top of the driven gear 17 is slidably connected to the bottom of the arc clamp 20. When the driven gear 17 rotates, it drives the arc clamp 20 to move towards the center through the crank connecting rod 18, thereby achieving strong compression and fixation at the connection between the feed pipe 9 and the lid 7.

[0020] A chassis 31 is slidably connected to the outside of the gear shaft 15. The chassis 31 provides support and guidance for the gear shaft 15, ensuring stability when the gear shaft 15 drives the drive gear 16 to rotate. The drive gear 16 is slidably connected to the top of the chassis 31. The drive gear 16 can slide smoothly on the chassis 31 and maintain a good meshing state with the driven gear 17, efficiently transmitting the power of the motor 14. The outer side of the drive gear 16 is meshed with the driven gear 17. This meshing transmission method accurately transmits the rotational power of the drive gear 16 to the driven gear 17, driving the pipe fixing mechanism to operate.

[0021] A motor 8 is fixedly connected to the top of the vessel lid 7. The motor 8 serves as the power core of the stirring device, outputting strong and stable power to drive the stirring shaft 13 to rotate. The stirring shaft 13 is rotatably connected to the bottom of the vessel lid 7. Driven by the motor 8, the stirring shaft 13 can rotate freely inside the vessel lid 7, transmitting power to the stirring blades 12. The stirring blades 12 are fixedly connected to the outside of the stirring shaft 13. The stirring blades 12 rotate at high speed with the stirring shaft 13, thoroughly stirring the chemical liquid inside the vessel body 3, ensuring uniform mixing of the reactants, and accelerating the chemical reaction process. A manhole 5 is fixedly connected inside the vessel lid 7, allowing operators to observe the reaction inside the vessel and perform operations such as adding materials and maintaining equipment. A thermometer 6 is slidably connected inside the vessel lid 7, monitoring the temperature changes inside the vessel in real time and providing data for operators to adjust the temperature of the medium inside the jacket 1.

[0022] A flange 4 is rotatably connected to the bottom of the vessel lid 7. The flange 4 fits tightly with the vessel lid 7 to form a sealed structure, preventing material leakage and the entry of external impurities during the reaction. The vessel body 3 is rotatably connected to the bottom of the flange 4, so that the vessel lid 7, flange 4 and vessel body 3 are tightly connected to form a closed reaction space, ensuring the safe and stable progress of the reaction. A jacket 1 is fixedly connected to the outside of the vessel body 3. The jacket 1 can be injected with heating or cooling media. By adjusting the temperature of the media, the reaction rate inside the vessel body 3 can be precisely controlled. A support leg 2 is fixedly connected to the bottom of the jacket 1. The support leg 2 provides stable support for the reactor, ensuring that the equipment remains balanced during operation and avoiding the impact of shaking on the reaction and sealing effect.

[0023] Working principle: After the worker connects the feed pipe 9 and the feed port on the lid 7, the motor 14 is started. The motor 14 drives the gear shaft 15, which in turn drives the drive gear 16 on the chassis 31. The drive gear 16 drives the driven gear 17 to rotate. The rotation of the driven gear 17 compresses the crank connecting rod 18 to move along the internal groove of the gear. The crank connecting rod 18 compresses the arc-shaped clamp 20 to move into the gear. The fixing plate 19 fixes the crank connecting rod 18, thereby forming a compression to fix the pipeline. The lid 7 and the flange 4 that contacts the lid 7 provide a sealing function. The support leg 2 supports the lid body 3.

[0024] After the pipeline is fixed, the worker starts the water pump 10 to draw the raw material from the raw material barrel 11 through the straight pipe 35. When the liquid enters the reactor body 3, the motor 8 is started. The motor 8 drives the stirring shaft 13, which drives the stirring blade 12 to rotate and stir the chemical liquid. The chemical reaction is monitored through the manhole 5 and the thermometer 6. The rate of chemical reaction in the reactor is controlled by adding heating or cooling medium through the jacket 1. When the chemical reaction is completed, the liquid flows through the feed pipe 21, through the conduit 22, and through the connecting pipe 23 into the three-way pipe port 24, which rotates to connect the left pipe 32 and the sleeve 33 into the water tank 34. The piston 25 is started to draw the liquid. After the liquid is full, the cylinder 29 extends and retracts, which drives the clamping plate 28 to move to the left, thereby driving the connecting plate 27 and the connecting rod 26 to make a clockwise arc movement, which drives the three-way pipe port 24 to rotate and connect to the left pipe water tank 34. The piston 25 squeezes the liquid into the water tank 34, and then the compression pump 30 squeezes the liquid out of the container to achieve the purpose of quantitative feeding.
