Description

Technical Field

[0001] This utility model relates to the field of adjustable carbonization tower technology, and in particular to an adjustable sieve plate carbonization tower. Background Technology

[0002] A carbonation tower is an industrial device used for gas-liquid carbonation reactions. It primarily reacts carbon dioxide gas with liquid reactants under specific conditions to produce carbonate products. It is a core piece of equipment in the soda ash industry, food carbonation, and environmental CO2 capture. A type of adjustable sieve plate carbonation tower is a chemical device used for gas-liquid reactions. Its core feature is the presence of one or more adjustable sieve plate structures within the tower. By changing parameters such as sieve plate aperture, open area ratio, interlayer spacing, or inclination angle, the gas-liquid contact efficiency is dynamically optimized to adapt to different process conditions, raw material characteristics, or product requirements.

[0003] To address this, patent CN200960451Y discloses a sieve-plate carbonization tower, comprising a tower body and a sieve plate disposed within the tower body. After this utility model device was put into production, it demonstrated good performance, ensuring orderly and stable gas-liquid flow, improving its corrosion resistance, and enhancing the operating conditions of the carbonization tower. Firstly, it increased the gas-liquid mass transfer area, improving the NaCl conversion rate of the carbonized extract to over 75%, while reducing raw material consumption. Secondly, it increased the output of the carbonization tower, increasing its production capacity by 20%. Thirdly, it produced uniform, large, and high-quality crystal particles, resulting in low impurity content in the alkali solution and minimal filtration loss. Furthermore, by reducing the thickness and weight of the sieve plate and changing the connection method to internal bolt fixing, disassembly and assembly are convenient during maintenance.

[0004] The sieve plate carbonization tower described above is not convenient for adjusting the aperture of the sieve plate during use, making it difficult to meet the reaction requirements of different materials, resulting in incomplete reaction or reduced efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable sieve plate carbonization tower to solve the problem that existing sieve plate carbonization towers are not convenient for adjusting the aperture size.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable sieve plate carbonization tower, including a tower body;

[0007] The top of the tower body is equipped with an end cap, and the inside of the tower body is equipped with an adjustment structure. The adjustment structure includes a first sieve plate installed inside the tower body, a second sieve plate installed at the top of the first sieve plate, a limit ring fixed at the bottom of the second sieve plate, an annular groove provided inside the first sieve plate outside the limit ring, a first sieve hole provided inside the second sieve plate, a second sieve hole provided inside the first sieve plate, an mounting plate installed at the top of the second sieve plate, a rotating shaft fixed at the top of the mounting plate, a rotating block fixed at the top of the rotating shaft, a rotating groove provided inside the end cap, a gear fixed outside the rotating shaft inside the rotating groove, a limit groove provided on one side of the rotating groove inside the end cap, and a rack installed on one side of the gear inside the limit groove.

[0008] The top of the first sieve plate is fixed with a telescopic structure.

[0009] Preferably, the first sieve plate and the second sieve plate have the same diameter, and guide grooves are provided on both sides of the interior of the tower body. Guide blocks are fixed on both sides of the first sieve plate inside the guide grooves, and the limiting ring and the first sieve plate are rotatably connected through an annular groove.

[0010] With the above structure, during use, the guide groove and guide block cooperate to restrict the first screen plate to move only in the vertical direction, preventing horizontal deviation, thereby ensuring that the second screen plate can rotate horizontally relative to the first screen plate.

[0011] Preferably, the first sieve holes are evenly spaced inside the second sieve plate, and the second sieve holes are evenly spaced inside the first sieve plate. The first sieve holes and the second sieve holes correspond one-to-one, and the diameters of the first sieve holes and the second sieve holes are the same.

[0012] With the above structure, during use, the rotation of the second sieve plate causes the first and second sieve holes to gradually shift, thereby achieving a gradual adjustment of the opening rate.

[0013] Preferably, the interior of the rotating groove is connected to the interior of the limiting groove, and the gear and rack are meshed.

[0014] With the above structure, during use, rotating the rotating block drives the gear to rotate, which in turn drives the meshing rack to move linearly, thereby controlling the second screen plate to automatically maintain its position after adjustment.

[0015] Preferably, the tower body and end cap are internally fitted with fixing bolts. The telescopic structure includes a fixing cylinder fixed at the bottom edge of the first sieve plate. A lifting rod is installed inside the fixing cylinder. A third sieve plate is fixed at the bottom end of the lifting rod. A third sieve hole is provided inside the third sieve plate. A first internal groove is provided inside the top end of the lifting rod. A first spring is fixed inside the first internal groove. A first locking block is fixed at one end of the first spring. A first locking groove is provided on one side of the fixing cylinder outside the first locking block. A second internal groove is provided inside the lifting rod at the bottom end of the first internal groove. A second spring is fixed inside the second internal groove. A second locking block is fixed at one end of the second spring. A second locking groove is provided on the other side of the fixing cylinder outside the second locking block.

[0016] Preferably, the fixed cylinders are evenly spaced at the bottom end of the first sieve plate, and the third sieve holes are evenly spaced inside the third sieve plate.

[0017] The above structure ensures that the third screen plate is subjected to uniform force during lifting and lowering, preventing the screen plate from tilting or shifting.

[0018] Preferably, the first locking block and the first built-in groove form a telescopic structure through the first spring, the first locking block and the fixed cylinder form a locking structure through the first locking groove, and the second locking block and the second built-in groove form a telescopic structure through the second spring.

[0019] With the above structure, the first and second locking blocks can extend and retract under the action of the first and second springs respectively during use, so that the lifting rod can be smoothly adjusted in height.

[0020] Preferably, the second locking block and the fixed cylinder form a locking structure through the second locking groove. One end of both the first locking block and the second locking block is arc-shaped. The first locking groove is evenly distributed on one side of the fixed cylinder, and the second locking groove is evenly distributed on the other side of the fixed cylinder.

[0021] With the above structure, during use, the first and second locking blocks form a mirror-symmetrical locking structure with the first and second locking slots on both sides of the fixed cylinder, thereby achieving a bidirectional stable locking function.

[0022] The adjustable sieve plate carbonization tower provided by this utility model has the following advantages:

[0023] By incorporating an adjustable structure, the opening and closing degrees of the first and second sieve plates can be adjusted to flexibly regulate the flow rate of gas or liquid, optimize the reaction contact area, and improve carbonization efficiency.

[0024] By incorporating a telescopic structure and adjusting the height of the third sieve plate, combined with sieve hole misalignment adjustment, multi-level control can be achieved to meet complex process requirements. Attached Figure Description

[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] Please see Figure 1-5 The present invention provides an adjustable sieve plate carbonization tower, comprising a tower body 1.

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, an end cap 2 is installed at the top of the tower body 1. Fixing bolts 3 are installed inside the tower body 1 and the end cap 2. An adjustment structure 4 is installed inside the tower body 1. The adjustment structure 4 includes a first sieve plate 401 installed inside the tower body 1. A second sieve plate 402 is installed at the top of the first sieve plate 401. A limit ring 403 is fixed at the bottom of the second sieve plate 402. An annular groove 404 is provided inside the first sieve plate 401 outside the limit ring 403. A first sieve hole 405 and a second sieve hole 406 are provided inside the second sieve plate 402. An mounting plate 407 is installed at the top of the second sieve plate 402. A rotating shaft 408 is fixed at the top of the mounting plate 407. A rotating block 409 is fixed at the top of the rotating shaft 408. A rotating groove 410 is provided inside the end cap 2. A tooth is fixed to the outside of the rotating shaft 408 inside the rotating groove 410. Wheel 411, end cover 2, the inner rotating groove 410 is provided with a limiting groove 412 on one side, the gear 411 inside the limiting groove 412 is equipped with a rack 413 on one side, the first screen plate 401 and the second screen plate 402 have the same diameter, the inner sides of the tower body 1 are provided with guide grooves, the inner sides of the first screen plate 401 are fixed with guide blocks, the limiting ring 403 and the first screen plate 401 are rotatably connected through the annular groove 404, the first screen hole 405 is evenly distributed inside the second screen plate 402, the second screen hole 406 is evenly distributed inside the first screen plate 401, the first screen hole 405 and the second screen hole 406 correspond one-to-one, the first screen hole 405 and the second screen hole 406 have the same diameter, the inner side of the rotating groove 410 is connected to the inner side of the limiting groove 412, the gear 411 and the rack 413 are meshed.

[0034] The first sieve plate 401 and the second sieve plate 402 are sequentially installed inside the tower body 1. The first sieve plate 401 is engaged with the guide groove inside the tower body 1 by a guide block to ensure that it can move in the vertical direction. The second sieve plate 402 can rotate relative to the first sieve plate 401 by a limiting ring 403 embedded in the annular groove 404 of the first sieve plate 401. Then, the rotating block 409 drives the rotating shaft 408, which drives the gear 411 to rotate. The gear 411 meshes with the rack 413, thereby pushing the second sieve plate 402. 02 Horizontal rotation achieves alignment or misalignment of the first sieve hole 405 and the second sieve hole 406 to adjust the opening and closing state of the sieve plate. When one end of the rack 413 abuts against one side of the inside of the limiting groove 412, the first sieve hole 405 and the second sieve hole 406 are completely aligned. At this time, the opening ratio is the largest. The meshing structure of the gear 411 and the rack 413 can maintain stability and prevent the sieve plate from rotating on its own. In turn, by adjusting the state of the sieve plate, the fluid distribution is more uniform, improving the efficiency of the carbonization reaction and the quality of the product.
