[0025] 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.

[0026] Please see Figures 1-7 This utility model provides a technical solution: a variable diameter sieve plate carbonization tower for soda ash preparation, including a base 1, a sieve plate 2, and a variable diameter carbonization tower body 3. The base 1 is installed above the variable diameter carbonization tower body 3, and the sieve plate 2 is snapped into the inner wall of the variable diameter carbonization tower body 3. The surface of the sieve plate 2 is provided with several holes 4. The base 1 provides a supporting foundation for the entire variable diameter carbonization tower, ensuring stable placement of the equipment. As a gas inlet channel, it guides external gas into the interior of the carbonization tower to participate in the reaction. The sieve plate 2 constructs a gas-liquid reaction zone inside the carbonization tower. Gas rises through the holes 4 on the surface to form bubbles, which fully contact the liquid on the sieve plate 2, promoting gas-liquid mass transfer and reaction. It separates the internal space of the carbonization tower, allowing the gas and liquid to form specific flow paths between different sieve plates 2, thus extending the reaction time. After the gas enters the tower from the base 1, it flows in the middle tower body 18 and the top tower body 19 with different diameters, and reacts with the liquid entering from the liquid inlet pipe 23 of the top tower body 19 at the sieve plate 2. The variable diameter structure changes the flow state of the gas and liquid, promoting a more complete reaction.

[0027] A fixing assembly for securing the sieve plate 2 is installed on one side. One end of the fixing assembly is connected to the inner wall of the variable-diameter carbonization tower body 3. The fixing assembly includes a support base 5, a positioning pin 6, a spring 7, and an operating rod 8. The support base 5 is L-shaped and is symmetrically installed on the inner wall of the variable-diameter carbonization tower body 3. The horizontal part of the L-shaped structure of the support base 5 bears the weight of the sieve plate 2, while the vertical part enhances the stability of the connection with the tower wall, ensuring that the sieve plate 2 will not be displaced due to the impact of gas and liquid during the operation of the carbonization tower. The positioning pin 6 is located on the support base. On the bottom surface of 5, a groove 9 is provided on the bottom of the screen plate 2. The positioning pin 6 is adapted to the groove 9 and is used to initially position the screen plate 2. A movable plate 11 is symmetrically installed on both sides of the positioning pin 6, with one side of each movable plate 11 fitting against one side of the positioning pin 6. A spring 7 is installed on the side of the movable plate 11 away from the positioning pin 6. When the operating lever 8 pushes the side plate 12 and the movable plate 11, the spring 7 is compressed, storing elastic potential energy. When the external force is removed, the spring 7 releases the elastic potential energy, pushing the movable plate 11 and the positioning pin 6 back to their original positions, allowing the positioning pin 6 to re-insert into the groove of the screen plate 2. The groove 9 serves to automatically lock the screen plate 2, ensuring the screen plate 2 is securely installed. Side plates 12 are symmetrically installed on the side of the moving plate 11 away from the positioning pin 6. One end of each operating rod 8 is installed at the rear end of the side plate 12. A square groove 10 is provided inside the support base 5. The operating rod 8 is vertically installed inside the square groove 10, with one end extending to the surface of the support base 5. A sealing strip 24 is installed on the surface of the square groove 10, tightly fitting against the surface of the square groove 10 to form a sealing structure surrounding the operating rod 8. The operating rod 8 is positioned within the sealing strip 24. The internal space enclosed by 4 has a certain amount of room for movement, allowing for limited swaying in the left and right directions. It also provides dust protection. When the screen plate 2 needs to be installed, the operating lever 8 pulls the side plate 12 outward, causing the moving plate 11 to compress the spring 7, which in turn causes the positioning pin 6 to retract to both sides. At this time, the screen plate 2 can be placed on the support base 5. The operating lever 8 is released, and the spring 7 rebounds and pushes the moving plate 11, causing the positioning pin 6 to insert into the groove 9 of the screen plate 2 to complete the fixation. The square groove 10 provides a moving track for the operating lever 8, ensuring that the operating lever 8 can stably pull the side plate 12.

[0028] The variable-diameter carbonization tower body 3 is internally equipped with an adjustment assembly for adjusting the holes 4 of the sieve plate 2. The adjustment assembly is located below the sieve plate 2 and connected at one end. The assembly includes an adjustment rod 13, a horizontal plate 14, and a vertical plate 15. The adjustment rod 13 is conical at the top and cylindrical at the bottom, corresponding to the holes 4. The fit between the cylindrical part and the holes 4 enhances the stability of the adjustment rod 13 within the holes 4. Under the impact of gas-liquid flow, the tight fit between the cylindrical part and the holes 4 reduces the shaking and offset of the adjustment rod 13, improving the reliability and accuracy of the adjustment. The adjustment rod 13 is installed on the top of the horizontal plate 14, which ensures the relative position stability of multiple adjustment rods 13. The installation of the adjustment rods 13 corresponds to the bottom of the holes 4. The top of the vertical plate 15 is installed at the bottom of the horizontal plate 14. The top of plate 15 is connected to the horizontal plate 14, and the bottom is connected to the drive assembly. The power of the drive assembly is transmitted to the horizontal plate 14 through the vertical plate 15, which in turn drives the adjusting rod 13 to move up and down. The connection structure between the horizontal plate 14 and the vertical plate 15 ensures the smooth transmission of force and ensures that the adjusting rod 13 can move accurately according to the instructions of the drive assembly, so as to achieve precise adjustment of the size of the holes 4 in the sieve plate 2. The bottom of the vertical plate 15 is connected to the drive assembly. When the drive assembly drives the horizontal plate 14 to move up and down, the adjusting rod 13 moves accordingly. When the adjusting rod 13 moves upward, the conical part enters the hole 4, gradually reducing the effective flow area of ​​the hole 4 and limiting the gas flow. When the adjusting rod 13 moves downward, the effective flow area of ​​the hole 4 increases, increasing the gas flow, thereby achieving the adjustment of the hole size of the sieve plate 2 to adapt to different reaction conditions.

[0029] The variable-diameter carbonization tower body 3 is internally equipped with a drive assembly for providing power to the adjustment component. One end of the drive assembly extends to the inner wall of the variable-diameter carbonization tower body 3, and one end of the adjustment component is connected to one end of the drive assembly. The drive assembly includes an electric push rod 16 and a fixing plate 17. The electric push rod 16 is symmetrically mounted on the inner wall of the variable-diameter carbonization tower body 3 via the fixing plate 17. The fixing plate 17 is used to fix the electric push rod 16 to the inner wall of the variable-diameter carbonization tower body 3. The piston rods of the electric push rods 16 are movably connected to the bottom of the vertical plate 15. The electric push rods 16 are connected to the vertical plate 15 via the fixing plate 17. Fixed plates 17 are symmetrically installed on the inner wall of the variable diameter carbonization tower body 3. When the electric push rod 16 receives the control signal from the controller 20, its internal motor runs, and the motor drives the lead screw to rotate. The lead screw and nut cooperate to convert the rotational motion into linear motion, causing the piston rod to extend or retract. The piston rod is movably connected to the bottom of the vertical plate 15, thereby driving the vertical plate 15, the horizontal plate 14 and the adjusting rod 13 to move up and down, thereby adjusting the size of the holes 4 of the sieve plate 2. The electric push rod 16 can precisely control the stroke and speed to meet the high precision requirements for adjusting the hole size of the sieve plate 2.

[0030] The variable diameter carbonization tower body 3 includes a middle tower body 18 and a top tower body 19. The sieve plates 2 are installed inside the middle tower body 18 and the top tower body 19. After the gas enters the middle tower body 18 from the base 1, the gas flow rate and pressure distribution change with the change of the tower body diameter. When the tower body diameter increases, the gas flow rate decreases, which is conducive to more complete contact and reaction between the gas and the liquid. When the tower body diameter decreases, the gas flow rate increases, which promotes more uniform gas-liquid mixing.

[0031] A controller 20 is installed on the top of the top tower body 19. Pressure differential sensors 21 are installed on both the upper and lower surfaces of the sieve plates 2. The controller 20 is electrically connected to the pressure differential sensors 21. The pressure differential sensors 21 are installed on the upper and lower surfaces of each sieve plate 2. The sensitive elements inside the sensors can sense the pressure changes on both sides of the sieve plate 2 and convert the pressure signal into an electrical signal. The base 1 is hollow. An air inlet pipe 22 is installed on one side of the base 1. One end of the air inlet pipe 22 is connected to the base 1, and the other end is connected to an external gas source. Under the pressure of the external gas source, gas flows into the base 1 through the air inlet pipe 22. A liquid inlet pipe 23 is installed on one side of the top tower body 19. One end of the liquid inlet pipe 23 is connected to the top tower body 19, and the other end is connected to an external liquid conveying device. Liquid is then pumped or conveyed by gravity. Under the action of the controller, the liquid participating in the carbonization reaction flows into the top tower body 19 through the liquid inlet pipe 23. The controller 20 receives the pressure difference data of the upper and lower surfaces of the sieve plate 2 collected by the pressure difference sensor 21 in real time. The controller 20 has a preset pressure difference range and control algorithm stored in its internal storage. When the received pressure difference data exceeds the set range, the controller 20 calculates the stroke and direction that the electric push rod 16 needs to be adjusted according to the control algorithm and sends the corresponding control signal to the electric push rod 16. When the pressure difference is too large, it means that the hole 4 of the sieve plate 2 may be too large and the gas flow rate is too fast. The controller 20 controls the electric push rod 16 to push the adjusting rod 13 to move upward and reduce the size of the hole 4. Conversely, when the pressure difference is too small, the controller controls the electric push rod 16 to pull the adjusting rod 13 to move downward and increase the size of the hole 4. This realizes the automatic adjustment of the hole size of the sieve plate 2 and maintains a stable gas-liquid reaction environment in the carbonization tower.
