Description

Technical Field

[0001] This invention belongs to the field of calcium carbonate processing technology, specifically a carbonation tower for processing nano-calcium carbonate. Background Technology

[0002] Nano-calcium carbonate is a calcium carbonate powder material with a particle size ranging from 1 to 100 nm. Its chemical nature is the same as that of ordinary calcium carbonate. Its core feature is that the particle size is precisely controlled at the nanoscale through artificial chemical synthesis, thus possessing special properties that ordinary micron-sized calcium carbonate does not have. In order to precisely control the particle size of calcium carbonate crystals to the nanoscale, regulate the crystal morphology, achieve ultrafine particle size, ensure the core performance of the product, and realize the large-scale production of nano-calcium carbonate, a carbonation process must be adopted in the processing. Carbonation is the core chemical reaction of lime milk and carbon dioxide to produce calcium carbonate, and it is also the key core step in the preparation of nano-sized calcium carbonate.

[0003] In existing technologies, carbonation reactors used in the processing and production of nano-calcium carbonate are mainly carbonation towers. To enhance the mixing and contact efficiency of the gas and liquid phases, precisely control the carbonation reaction process, and ensure the quality stability of products such as nano-calcium carbonate, existing carbonation towers are generally equipped with stirring facilities to ensure full contact between gas and liquid. However, in actual use, stirring still cannot solve the problems of stirring dead zones, material agglomeration, and density stratification, which not only reduces the production quality of calcium carbonate but also leads to significant limitations in the application of carbonation towers.

[0010] Preferably, it includes a stress-relieving square column, which is installed on the side of the pressure-bearing base near the inner bottom surface of the U-shaped base; The pressure relief square tube is connected to the pressure base plate on the side close to the pressure bearing base; the end of the pressure relief square column away from the pressure bearing base is located inside the pressure relief square tube, and the two are fitted together; the pressure relief square tube and the pressure relief square column are slidably fitted together.

[0015] Preferably, it includes suction pipes, which are respectively installed on the side of the annular pipe and the transfer pipe near the pressure plate; the number and position of the suction pipes correspond one-to-one with the suction cups; the end of the suction pipe away from the annular pipe and the transfer pipe is located inside the suction cup.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The stirring power is provided by the continuous small-amplitude left and right swaying of the tower body. The continuous left and right swaying of the tower body and the stirring use the same driving source, which reduces the energy consumption when the carbonization tower is used and reduces its application limitations. This also makes the gas and liquid continuously follow the left and right swaying of the tower body while being stirred, constantly dispersing the gas and liquid distribution position, avoiding dead corners during stirring, and avoiding the problems of material agglomeration and density stratification. This makes the gas and liquid constantly change position in the tower body to receive stirring, strengthen the gas-liquid contact, not only improve the production quality of calcium carbonate, but also further reduce the application limitations of the carbonization tower. (2) When the tower body is actively controlled to swing left and right in small amplitudes, the pressure-bearing circular plate connected to the bottom of the tower body will rotate under the action of the stress relief and energy-lowering mechanism, causing the guide block on it to slide back and forth along the guide semi-ring continuously. This allows the guide block to rotate around the guide semi-ring, thereby limiting the rotation of the pressure-bearing circular plate and preventing it from dislodging. At the same time, it limits the rotation angle and position of the tower body on the pressure-bearing circular plate, preventing the pressure-bearing circular plate from swaying back and forth with the tower body. This improves the swing stability of the tower body, allowing the gas and liquid inside to mix evenly, further improving the production quality and grade of calcium carbonate. It is worth mentioning that when the guide block swings left and right on the guide semi-ring continuously, it continuously compresses the guide spring, thus... The constant buffering and resetting process absorbs and reduces the impact force on the tower body during its continuous left-right oscillation caused by the pressure plate, further enhancing the stability of the carbonization tower. Simultaneously, when the guide spring is compressed and the tower body needs to reset, the power source can be shut off, eliminating the force acting on the tower body. This causes the guide spring, which is in a buffered state, to reset, thus resetting the tower body. This repetitive cycle reduces the energy consumption of the carbonization tower and allows for the selection of a lower-cost motor, eliminating the need for a high-cost reciprocating motor. This further reduces the limitations of the carbonization tower's application, making it more environmentally friendly and improving its performance, thereby ensuring the production efficiency and quality of the carbonization tower. (3) The power source output end rotates back and forth slightly, driving the tower body to move back and forth, that is, to swing back and forth continuously, so that the gas and liquid inside also move together, so that the components in the gas and liquid move continuously and come into contact with each other, avoiding the problems of insufficient gas-liquid contact, uneven material distribution leading to slow carbonization reaction rate, low conversion rate, uneven nano-calcium carbonate particle size, disordered crystal form, quality fluctuation and poor batch stability; at the same time, when the tower body swings back and forth slightly, the rotating gear on it also continuously meshes with the half-tooth ring and rotates, so that the rotating gear drives the stirring shaft inside the tower body to rotate back and forth, so that the stirring rods on it continuously rotate inside the tower body, continuously contact the gas and liquid inside the tower body, so that they are evenly mixed, and the agglomerated material is broken up. The repeated contact with gas and liquid ensures that the gas and liquid are fully contacted, thereby improving the carbonization reaction rate and conversion rate of the carbonization tower during use. (4) When the tower body is stirred or reciprocating, the gas and liquid inside it continuously impact the inner wall of the tower body, causing the tower body to shake. The force generated by the shaking is transmitted to the pressure base through the pressure-bearing circular plate, so that the unloading square column on it can move within the unloading square tube, so that the tower body can unload when it is subjected to impact force. At the same time, the compression spring in the unloading square tube is in a buffer state, and the resulting buffer force is used to further reduce and absorb the impact force on the tower body during use, realize the unloading buffer when the tower body is subjected to impact force, thereby further improving the stability of the tower body during gas-liquid stirring and reciprocating swing, so that the production quality and quality of calcium carbonate can be guaranteed, thereby improving the use effect of the carbonation tower and ensuring its service life. (5) When the tower body is in use, its bottom contacts the pressure-bearing circular plate, which not only supports the tower body and prevents it from dislodging when it swings left and right, but also improves the stability of the tower body. At the same time, by starting the air pump, the input end of the pump generates suction. The suction is transmitted to the air extraction pipe through the cooperation of the transfer pipe, hollow pipe and annular pipe. The air extraction pipe port is also set in the suction cup, so that the air inside is extracted by the air pump. When the bottom of the tower body contacts the pressure-bearing circular plate, it also contacts several suction cups at the same time. By extracting the gas in several suction cups at the same time, the contact surface between the bottom of the tower body and the pressure-bearing circular plate is made into a vacuum state, so that the tower body is adsorbed and fixed on the pressure-bearing circular plate, preventing the tower body from dislodging when it swings left and right. This improves the installation effect and stability of the tower body, and also ensures the safety of the carbonation tower, thereby further improving the production quality of calcium carbonate.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Implementation examples, by Figures 1 to 10 The present invention includes a U-shaped base 1; a tower body 2; the tower body 2 is located inside the opening of the U-shaped base 1; a complex control mixing device is provided on the U-shaped base 1 for slightly shaking the tower body 2 to achieve full contact between the gas and liquid inside; the complex control mixing device includes a rotating shaft 3, installed on opposite sides of the U-shaped base 1; the opposite ends of the two rotating shafts 3 are connected to the outer wall of the tower body 2; a pressure-bearing circular plate 4 is located inside the U-shaped base 1; the pressure-bearing circular plate 4 is disposed at the bottom of the tower body 2, and the two are in contact; a power source 8 is installed on the side of the U-shaped base 1; and a rotating groove 9. A rotating shaft 3 is located on the side away from the tower body 2; the output end of the power source 8 passes through the side of the U-shaped base 1 and engages with the rotating groove 9; a half-toothed ring 10 is installed on the U-shaped base 1; the half-toothed ring 10 is coaxial with the center of the rotating shaft 3; a stirring shaft 11 is installed inside the tower body 2; a stirring rod 12; several stirring rods 12 are connected to the stirring shaft 11; a rotating gear 13 is installed on the outer wall of the tower body 2; the rotating gear 13 is rotatably connected to the stirring shaft 11; the rotating gear 13 is meshed with the half-toothed ring 10. Turn on the switch of power source 8 to make its output end rotate. The output end of power source 8 is engaged with the rotating groove 9, so that when the output end of power source 8 rotates, it synchronously drives the rotating shaft 3 to rotate, which in turn makes the tower body 2 on it rotate. It is worth mentioning that power source 8 can be a reciprocating motor, so that its output end rotates back and forth in a small amplitude, thereby driving the tower body 2 to reciprocate, that is, to swing back and forth continuously from left to right. This causes the gas and liquid inside to move together, so that the components in the gas and liquid move continuously and come into contact with each other. This avoids the problems of insufficient gas-liquid contact, uneven material distribution, slow carbonization reaction rate, low conversion rate, uneven nano-calcium carbonate particle size, disordered crystal form, quality fluctuation and poor batch stability. Meanwhile, as the tower body 2 swings back and forth in small amplitudes, the rotating gear 13 on it continuously meshes with the half-tooth ring 10 and rotates, causing the rotating gear 13 to drive the stirring shaft 11 inside the tower body 2 to rotate back and forth. This causes the stirring rods 12 on it to rotate continuously inside the tower body 2, continuously contacting the gas and liquid inside the tower body 2, so that they are evenly mixed and the clumps of material are broken up. The repeated contact between the gas and liquid ensures that the gas and liquid are fully in contact, thereby improving the carbonization reaction rate and conversion rate of the carbonization tower during use. It is worth mentioning that the aforementioned stirring power is provided by the continuous small-amplitude left-right swaying of the tower body 2. This allows the continuous left-right swaying of the tower body 2 and the stirring to share a single driving source, reducing the energy consumption during the use of the carbonation tower and thus minimizing its limitations. This also ensures that while the gas and liquid are stirred within the tower body 2, they also continuously follow the left-right swaying motion, constantly dispersing the gas and liquid distribution, avoiding dead zones during stirring, and preventing material agglomeration and density stratification. This continuous change in the position of the gas and liquid within the tower body 2 enhances the contact between them, improving the production quality of calcium carbonate and further reducing the application limitations of the carbonation tower.

[0021] The stress relief and energy mitigation mechanism of this embodiment is disposed on the pressure-bearing circular plate 4. The stress relief and energy mitigation mechanism is used to absorb the impact force generated during stirring and mixing in the tower body 2. The stress relief and energy mitigation mechanism includes a pressure-bearing base 5, which is installed on the outer wall of the pressure-bearing circular plate 4; a stress relief column 18, which is installed on the side of the pressure-bearing base 5 near the inner bottom surface of the U-shaped base 1; a stress relief cylinder 19, which is connected to the pressure base plate 16 near the pressure-bearing base 5; the end of the stress relief column 18 away from the pressure-bearing base 5 is located inside the stress relief cylinder 19, and the two are fitted together; the stress relief cylinder 19 and the stress relief column 18 are in sliding fit; a compression spring 20 is disposed inside the stress relief cylinder 19; one end of the compression spring 20 is fixedly connected to the inner bottom surface of the stress relief cylinder 19; the other end of the compression spring 20 is fixedly connected to the stress relief column 18. The tower body 2 is fixed to the pressure-bearing circular plate 4 by adsorption. When the tower body 2 is stirred or reciprocating, the gas and liquid inside it continuously impact the inner wall of the tower body 2, causing the tower body 2 to shake. The force generated by the shaking is transmitted to the pressure-bearing base 5 through the pressure-bearing circular plate 4, which allows the unloading column 18 on it to move within the unloading cylinder 19. This allows the tower body 2 to unload the force when it is subjected to impact. At the same time, the compression spring 20 inside the unloading cylinder 19 is in a buffer state. The resulting buffering force is used to further reduce and absorb the impact force received by the tower body 2 during use, realizing the unloading and buffering of the tower body 2 when it is subjected to impact force. This further improves the stability of the tower body 2 during gas-liquid stirring and reciprocating shaking, ensuring the production quality of calcium carbonate, thereby improving the use effect of the carbonation tower and ensuring its service life.

[0022] The anti-deviation guide assembly of this embodiment is disposed on the U-shaped base 1; the anti-deviation guide assembly is used to limit the sway range of the tower body 2; the anti-deviation guide assembly includes a guide base 6; two guide bases 6 are installed on both sides of the U-shaped base 1; a guide semi-ring 14, the two ends of which are connected to the opposite surfaces of the two guide bases 6; the guide semi-ring 14 is coaxial with the center of the rotating shaft 3; a guide rotating block 15 is connected to the guide semi-ring 14 through the side; the guide rotating block 15 is slidably engaged with the guide semi-ring 14; a pressure plate 16 is also installed on the guide rotating block 15; a guide spring 17; the guide spring 17 is arc-shaped and sleeved on the guide semi-ring 14; one end of the guide spring 17 is fixedly connected to the guide rotating block 15, and the other end is fixedly connected to the guide base 6; Since the tower body 2 is fixed to the pressure plate 4 by the suction bonding unit during use, when the tower body 2 is actively controlled to swing left and right in small amplitudes, the pressure plate 4 connected to the bottom of the tower body 2 will drive the pressure plate 16 to rotate under the action of the stress relief and energy mitigation mechanism. This causes the guide block 15 on it to slide back and forth along the guide half ring 14, so that the guide block 15 rotates around the guide half ring 14. This limits the rotation of the pressure plate 4 and prevents it from dislodging. At the same time, it limits the rotation angle and position of the tower body 2 on the pressure plate 4, preventing the pressure plate 4 from shaking when it swings back and forth with the tower body 2. This improves the swing stability of the tower body 2, allowing the gas and liquid inside to mix evenly, and further improving the production quality and grade of calcium carbonate. It is worth mentioning that when the guide block 15 continuously swings left and right on the guide semi-ring 14, it continuously compresses the guide spring 17, keeping it in a buffered and reset state. The resulting buffering force is used to absorb and reduce the impact force suffered by the tower body 2 during the continuous left and right swinging of the pressure plate 4, further improving the stability of the tower body 2, i.e., the carbonization tower. At the same time, when the guide spring 17 is compressed and the tower body 2 needs to be reset and rotated, the power source 8 can be turned off, and the force acting on the tower body 2 will disappear, causing the guide spring 17, which is in a buffered state, to reset and drive the tower body 2 to reset. Repeating this process can reduce the energy consumption of the carbonization tower. At the same time, a lower-cost motor can be selected as needed, eliminating the need for a high-cost reciprocating motor, further reducing the limitations of the carbonization tower application, making the carbonization tower more environmentally friendly during use, thereby improving its performance and ensuring the production effect and quality of the carbonization tower.

[0023] The suction-bonding unit of this embodiment is disposed on the pressure-bearing circular plate 4; the suction-bonding unit is used to enhance the installation strength of the tower body 2; the suction-bonding unit includes a support frame 7, which is installed on the side of the pressure-bearing circular plate 4 away from the tower body 2; several support frames 7 are arranged in a circumferentially spaced manner with the center of the pressure-bearing circular plate 4 as the center; an auxiliary slot 21 is disposed on the side of the pressure-bearing circular plate 4 near the bottom of the tower body 2; a suction cup 22 is fitted into the auxiliary slot 21; when the pressure-bearing circular plate 4 contacts the bottom of the tower body 2, the suction cup 22 also contacts the bottom of the tower body 2; an annular pipe 23 is disposed on the side of the pressure-bearing circular plate 4 away from the tower body 2; several support frames 7 are connected together to the outer wall of the annular pipe 23; the annular pipe 23 The pressure-bearing circular plate 4 is coaxial with its center; a retaining frame 24 is connected to the side of the pressure-bearing circular plate 4 away from the tower body 2; an air pump 25 is installed inside the retaining frame 24; a transfer pipe 26 is installed on the input end of the air pump 25; a hollow pipe 27; one end of several hollow pipes 27 is connected to the outer wall of the transfer pipe 26, and the other end is connected to the annular pipe 23; the hollow pipes 27 are connected to the transfer pipe 26 and the annular pipe 23; air extraction pipes 28 are installed on the side of the annular pipe 23 and the transfer pipe 26 near the pressure-bearing circular plate 4; the number and position of the air extraction pipes 28 correspond one-to-one with the suction cups 22; the end of the air extraction pipe 28 away from the annular pipe 23 and the transfer pipe 26 is located inside the suction cups 22; When in use, the bottom of the tower body 2 can contact the pressure-bearing circular plate 4. This not only supports the tower body 2, preventing it from dislodging when swinging left and right, but also improves the stability of the tower body 2. At the same time, by activating the vacuum pump 25, a suction force is generated at its input end. The suction force is transmitted to the vacuum pipe 28 through the cooperation of the transfer pipe 26, the hollow pipe 27, and the annular pipe 23. The port of the vacuum pipe 28 is also located in the suction cup 22, so that the air inside is drawn out by the vacuum pump 25. When the bottom of the tower body 2 contacts the pressure-bearing circular plate 4, it also contacts several suction cups 22. By simultaneously drawing out the gas in several suction cups 22, the contact surface between the bottom of the tower body 2 and the pressure-bearing circular plate 4 is made into a vacuum state, so that the tower body 2 is adsorbed and fixed on the pressure-bearing circular plate 4. This prevents the tower body 2 from dislodging when it swings left and right, improves the installation effect and stability of the tower body 2, and ensures the safety of the carbonation tower, thereby further improving the production quality of calcium carbonate.
