Description

Technical Field

[0001] This utility model relates to a mineralization reaction device, specifically to a multi-stage carbon dioxide mineralization reaction filling body generation device. Background Technology

[0002] With the accelerated advancement of the global carbon neutrality strategy, carbon dioxide mineralization technology has demonstrated enormous application potential in building materials, mine backfilling, and industrial solid waste resource utilization. This technology, by reacting carbon dioxide with calcium- and magnesium-rich solid materials (such as steel slag, fly ash, and tailings), not only achieves permanent carbon dioxide sequestration but also significantly improves the mechanical properties of backfill materials and reduces the use of traditional cementitious materials. Therefore, developing efficient carbon dioxide mineralization reaction backfill material generation devices is of great significance for optimizing the reaction process, improving carbon dioxide utilization, ensuring uniform mineralization of backfill materials, and promoting the achievement of carbon neutrality goals.

[0003] In the prior art, for example, patent publication number CN220576290U discloses a carbon dioxide mineralization curing reaction device, which includes a support frame with a notch at the bottom and a sliding groove inside; a sleeve rotatably mounted on the support frame. This solution, through the arrangement of stirring components, can perform large-area stirring when the mixture of carbon dioxide, concrete, and water is injected into the reactor. The crossbars and U-shaped rods can prevent the mixture of concrete and water from adhering to the inner wall of the reactor, avoiding the situation where the introduced carbon dioxide can only react with the upper layer of concrete and water mixture. This solution, through the arrangement of pushing components, can reciprocate the connecting parts and the reactor to promote the overall stirring of the stirring components, so as to achieve a high degree of fullness of reaction between carbon dioxide and the mixture of concrete and water.

[0004] Based on existing technology, traditional carbon dioxide mineralization reaction packing material generation devices have several drawbacks. First, the reaction products (such as calcium carbonate and magnesium carbonate) form a dense layer on the material surface, hindering further diffusion of carbon dioxide into the interior, leading to a sharp decline in reaction efficiency over time. Second, most traditional carbon dioxide mineralization reaction packing material generation devices cannot adjust the carbon dioxide flow rate according to actual reaction requirements, easily leading to excessive carbon dioxide supply, further wasting resources and increasing costs, or insufficient carbon dioxide supply, resulting in incomplete reaction. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-stage carbon dioxide mineralization reaction filling material generation device, which enables carbon dioxide to fully carry out mineralization reaction in materials, prevents the formation of a dense layer on the material surface, and improves reaction efficiency; at the same time, it can precisely control the amount of carbon dioxide introduced according to actual reaction needs, avoid resource waste and reduce costs under the premise of complete mineralization reaction.

[0006] To solve this technical problem, the present invention adopts the following technical solution:

[0007] A multi-stage carbon dioxide mineralization reaction filling material generation device includes a sealed cylinder with a cylinder cover on top. The cylinder cover is fixed to the sealed cylinder by bolts. A carbon dioxide detector is installed on the cylinder cover to detect the carbon dioxide concentration in the sealed cylinder.

[0028] 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.

[0029] like Figure 1 As shown, this utility model includes a sealing cylinder 1, and a detachable cylinder cover 5 is provided on the top of the sealing cylinder 1. The cylinder cover 5 is fixed to the sealing cylinder 1 by bolts. A sealed space is formed between the sealing cylinder 1 and the cylinder cover 5. A sealing ring is sandwiched between the bottom surface of the cylinder cover 5 and the top surface of the sealing cylinder 1. The sealing ring can effectively improve the airtightness of the internal space of the sealing cylinder 1.

[0030] The cylinder head 5 is equipped with a carbon dioxide detector 7 (specifically an SCD41 sensor) and a PLC board. The carbon dioxide detector 7 and the PLC board are electrically connected. The detection probe of the carbon dioxide detector 7 is located inside the sealed cylinder 1 and is used to detect the carbon dioxide concentration in the sealed cylinder 1. The PLC board is fixed to the outer wall of the sealed cylinder 1. By setting up the carbon dioxide detector 7, the carbon dioxide concentration in the sealed cylinder 1 can be detected in real time, thereby controlling the opening and closing of the air pump 8 and the water pump 61, and accurately controlling the amount of carbon dioxide and water introduced. Under the premise of complete mineralization reaction, resource waste is further avoided.

[0031] The sealed cylinder 1 is equipped with a water supply assembly 6 for supplying water to the internal mineralization reaction. A gas storage cylinder 9 is located beside the sealed cylinder 1, and the gas storage cylinder 9 is connected to the sealed cylinder 1 via a one-way air pump 8. The air pump 8 is electrically connected to the PCL plate.

[0032] like Figure 2As shown, the sealing cylinder 1 is equipped with an air guide ring 3, combined with... Figure 3 As shown, an air inlet pipe 31 is provided laterally on one side of the air guide ring 3. The end of the air inlet pipe 31 extends from the side wall of the sealed cylinder 1 and is connected to the air outlet of the air pump 8. Several connecting pipes 32 are provided at equal intervals at the lower end of the air guide ring 3. The lower end of each connecting pipe 32 is connected to a stirring component 4. Each stirring component 4 has a reaction tank 2 at its bottom. All reaction tanks 2 are located at the bottom of the sealed cylinder 1 and are distributed circumferentially at equal intervals.

[0033] Combination Figure 4 and Figure 5 As shown, the agitation assembly 4 includes a sliding cylinder 41 fixed to the connecting pipe 32. The upper end of the sliding cylinder 41 is coaxially connected to the lower end of the connecting pipe 32 by bolts. A sliding block 42 is provided inside the sliding cylinder 41, and the sliding block 42 is slidably connected to the sliding cylinder 41. Specifically, a plurality of spiral grooves 411 are equidistantly arranged on the inner wall of the sliding cylinder 41, and a spiral strip is provided on the side wall of the sliding block 42, which cooperates with each spiral groove 411. Each spiral strip is slidably connected in its corresponding spiral groove 411. Specifically, since the spiral grooves 411 guide the spiral strips on the outer wall of the sliding block 42, the sliding block 42 rotates itself when it moves up and down inside the sliding cylinder 41. Figure 8 As shown, a storage groove 43 is formed in the center of the sliding block 42. Both the upper and lower ends of the storage groove 43 are open. A first spring 431 and a ball valve 432 are disposed within the storage groove 43. The bottom end of the first spring 431 is called a fixing ring, and the top end is called an abutment ring. The fixing ring is fixed to the bottom of the storage groove 43, and the abutment ring is welded to the bottom of the ball valve 432. The diameter of the ball valve 432 is larger than the upper opening of the storage groove 43. The first spring 431 provides support for the ball valve 432. When the ball valve 432 is in close contact with the upper opening of the storage groove 43, gas inside the sliding cylinder 41 cannot enter the storage groove 43. A duct 421 is fixed to the lower side of the sliding block 42. The upper end of the duct 421 is connected to the lower end of the storage tank 43. Four equidistant exhaust holes 422 are opened at the bottom of the side wall of the duct 421. A second spring 44 is sleeved on the outer side of the duct 421. The top end of the second spring 44 abuts against the bottom surface of the sliding block 42, and the bottom end of the second spring 44 abuts against the inner bottom surface of the sliding cylinder 41. The elastic coefficient of the second spring 44 is less than that of the first spring 431. A rotating cone 45 is fixed to the bottom end of the duct 421. Several turbulence vanes 451 are equidistantly arranged on the outer wall of the rotating cone 45, and each turbulence vane 451 is perpendicular to the rotating cone 45.

[0034] By setting up the stirring component 4, the material is stirred and dispersed, preventing the formation of a dense layer on the surface of the material after the carbon dioxide reacts with the material in a mineralization reaction. This avoids the carbon dioxide being unable to continue to react fully with the material, improves reaction efficiency, reduces resource waste, and lowers reaction costs.

[0035] like Figure 6 and Figure 7 As shown, the drainage assembly includes a water pump 61 located on top of the cylinder head 5. The water pump 61 is fixedly connected to the cylinder head 5 by bolts, and the water pump 61 is electrically connected to the PCL plate. A main water supply pipe 62 is connected to the bottom (outlet) of the water pump 61. Six branch water supply pipes 621 are equidistantly arranged around the bottom circumference of the main water supply pipe 62, and the outlet of each branch water supply pipe 621 is located above the corresponding reaction tank 2. The main water supply pipe 62 and each branch water supply pipe 621 are all located inside the sealed cylinder 1.

[0036] The multi-stage carbon dioxide mineralization reaction filling material generation device of this utility model is used as follows:

[0037] Materials are added to all reaction vessels 2, and then the cylinder cover 5 is fixed to the top of the sealed cylinder 1 with bolts. The one-way air pump 8 is turned on, and carbon dioxide in the gas storage bottle 9 is drawn into the gas guide ring 3 through the air inlet pipe 31, and then into each connecting pipe 32, and then into the interior of each stirring component 4.

[0038] As the air pressure increases, the sliding block 42 rotates and slides downward under the pressure of the air pressure in each stirring component 4. The second spring 44 is gradually compressed, and the air guide pipe 421 drives the rotating cone 45 to rotate downward. The turbulence vanes 451 on the rotating cone 45 can stir and disperse the material in the reaction tank 2.

[0039] When the second spring 44 is compressed to its maximum extent (the sliding block 42 slides to the bottom of the sliding cylinder 41), the rotating cone 45 reaches the bottom of the reaction tank 2. The air pressure then acts on the first spring 431, causing it to compress and deform. The ball valve 432 moves downward, opening the top of the storage tank 43. Carbon dioxide can then pass through the top and bottom openings of the storage tank 43, eventually entering the gas guide pipe 421 and being discharged through the exhaust port 422 into the material gap, where it undergoes a thorough mineralization reaction with the already stirred and dispersed material. At this time, the carbon dioxide detector 7 detects an increase in carbon dioxide concentration and sends an electrical signal to the PLC board. The PLC board then sends an electrical signal to the water pump 61, which turns on. Water is output from the bottom of the water pump 61, passing through the main water supply pipe 62 and the branch water supply pipe 621, and finally falling into each reaction tank 2, promoting the mineralization reaction in the reaction tank 2.

[0040] When the carbon dioxide detector 7 detects that the carbon dioxide concentration has reached its maximum value, it sends an electrical signal to the PLC board, which in turn sends an electrical signal to the air pump 8. The air pump 8 shuts down, and carbon dioxide stops being drawn into the sealed cylinder 1. As the material undergoes a mineralization reaction with the carbon dioxide, the carbon dioxide in the sealed cylinder 1 gradually decreases, causing the gas pressure to gradually drop. The second spring 44 rebounds, and the ball valve 432 re-seals the top opening of the storage tank 43, preventing carbon dioxide gas from escaping through the exhaust port 422 via the gas guide pipe 421. At this time, the carbon dioxide detector 7 detects a decrease in carbon dioxide concentration and sends an electrical signal to the PLC board, which in turn sends an electrical signal to the water pump 61. The water pump 61 shuts down, stopping the supply of water to the reaction tank 2.

[0041] Then the first spring 431 rebounds, and the sliding block 42 rotates and rises in the sliding cylinder 41, which drives the gas guide pipe 421 and the rotating cone 45 to rotate and rise together. The turbulence vanes 451 on the rotating cone 45 stir and disperse the material in the reaction tank 2 again, preventing the formation of a dense layer on the surface of the material, promoting the full mixing of carbon dioxide and the material, and continuing the mineralization reaction.

[0042] The process continues until the first spring 431 returns to its original state, thus completing one round of mineralization reaction and filling material generation. This process is repeated continuously until the filling material generation is complete.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
