Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate carbonation technology, specifically to a multi-compartment carbonation device. Background Technology

[0002] In the process of calcium carbonate carbonation, lime slurry is injected into the carbonation tank, and then carbon dioxide gas is introduced. The carbon dioxide gas reacts with the lime slurry to produce calcium carbonate precipitate.

[0003] Chinese patent CN212024797U discloses a calcium carbonate carbonation tower, including a tower body. The top of the tower body is equipped with a stirring device, a feed inlet, and a vent. Ventilation pipes are symmetrically distributed on the side walls of the tower body, interconnected at the bottom. Each ventilation pipe has several air holes covered by a diffuser plate. The bottom of the ventilation pipes has a first inlet pipe and a second inlet pipe, both equipped with air valves. The bottom of the tower body has a discharge outlet and a base. However, this device still has the following problems during use:

[0004] The gas inlet pipe of the device is located on one side of the reaction tower. When the carbonization reaction begins, carbon dioxide gas flows out from one side and reacts with the substances in the calcium hydroxide slurry on the same side first. This causes the calcium hydroxide slurry on both sides of the reaction tower to not be able to mix evenly with the carbon dioxide gas in time, resulting in inconsistent carbonization speed and reduced calcium carbonate production quality.

[0005] Based on this, the present invention designs a multi-compartment carbonization device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-compartment carbonization device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-compartment carbonization device includes a reactor, a multi-compartment synchronous mixing mechanism, and a baffle. A baffle is fixedly installed in the middle of the reactor's interior, dividing the reactor into upper and lower compartments. The upper compartment is a calcium hydroxide slurry stirring compartment, and the lower compartment is a mixing compartment. A multi-compartment synchronous mixing mechanism is installed at the upper end of the reactor to stir the materials in the calcium hydroxide slurry stirring compartment and the mixing compartment at different speeds. The multi-compartment synchronous mixing mechanism includes a drive assembly for controlling the movement of a movable component, a movable component for driving a spiral stirring blade, and spiral stirring blades. The drive assembly is installed at the upper end of the reactor, and the movable component is mounted on the drive assembly. Two spiral stirring blades are fixedly installed on the movable component.

[0009] Furthermore, it also includes a gas guide pipe, a gas guide ring, and a flow rate regulating mechanism. The gas guide pipe is fixedly installed on the lower side of the reactor; the gas guide ring is fixedly installed on the inner bottom of the reactor; and the gas guide pipe is connected to the gas guide ring; the outer end of the gas guide pipe is connected to a gas pump; the gas guide ring is provided with multiple first gas guide holes and multiple second gas guide holes, which are staggered and evenly distributed in a circumferential array on the gas guide ring; the carbon dioxide gas flow rate inside the gas guide pipe is constant.

[0010] The gas guide ring is equipped with a flow rate regulating mechanism that controls the closure of the first or second gas guide hole to change the flow rate of carbon dioxide gas; a calcium hydroxide slurry inlet is provided above the reactor.

[0011] Furthermore, the size of the first air guide hole is smaller than the size of the second air guide hole;

[0012] Furthermore, the drive assembly includes a support frame, a small drive gear, a large drive gear, and a control drive assembly for controlling the simultaneous rotation of the small drive gear and the large drive gear. The support frame is fixedly installed at the upper end of the reactor, and the control drive assembly is installed on the upper right side of the support frame. The small drive gear is rotatably installed on the inner top right side of the support frame. The large drive gear is rotatably installed on the inner bottom right side of the support frame. The control drive assembly is connected to the small drive gear and the large drive gear. Both the small drive gear and the large drive gear are connected to the movable assembly.

[0013] Furthermore, the movable component includes a driven pinion, a driven gear, a first rotating shaft, and a second rotating shaft. The upper end of the first rotating shaft is rotatably mounted on the bottom left side of the support frame, and the lower end of the first rotating shaft is rotatably mounted in the middle of the baffle. The second rotating shaft is disposed inside the first rotating shaft and rotatably connected to it. The upper end of the second rotating shaft is rotatably mounted on the top left side of the support frame, and the lower end of the second rotating shaft is rotatably mounted on the bottom of the reactor. The driven pinion is fixedly mounted on the upper end of the first rotating shaft. The driven gear is fixedly mounted on the upper end of the second rotating shaft. The driving pinion meshes with the driven gear. The driving gear meshes with the driven pinion. A spiral stirring blade is fixedly mounted on the outer end of the first rotating shaft. A spiral stirring blade is also fixedly mounted below the outer end of the second rotating shaft.

[0014] Furthermore, the flow rate regulating mechanism includes a sliding ring, a third air guide hole, an inner magnetic block, an outer magnetic block, a limiting slide rail, and a limiting plate. The sliding ring is rotatably connected to the outer end of the air guide ring, and the sliding ring is provided with multiple third air guide holes. The inner magnetic block is fixedly installed on the sliding ring. The limiting slide rail is fixedly installed below the outer end of the reactor, and limiting plates are fixedly installed at both ends of the limiting slide rail. The outer magnetic block is slidably connected to the limiting slide rail. The inner magnetic block and the outer magnetic block are attracted to each other.

[0015] Furthermore, the size of the third air guide hole is the same as the size of the second air guide hole;

[0016] Furthermore, the third air guide holes are evenly distributed in a circular array on the sliding ring.

[0017] Compared with the prior art, the advantages of this invention are as follows: When the calcium carbonate carbonation operation begins, the calcium hydroxide slurry enters the calcium hydroxide slurry stirring chamber through the feed inlet above the reactor. Subsequently, the drive assembly operates, causing the movable assembly to move. The spiral stirring blades move along with the movable assembly. At this time, the rotating spiral stirring blades rapidly stir the calcium hydroxide slurry in the stirring chamber, quickly dispersing any precipitates and ensuring uniform mixing with carbon dioxide gas. After the calcium hydroxide slurry is fully stirred, the flow control valve opens the channel between the calcium hydroxide slurry stirring chamber and the mixing chamber. At this point, the fully stirred calcium hydroxide slurry... The gas flows downwards into the mixing chamber, and then the channel between the calcium hydroxide slurry stirring chamber and the mixing chamber is closed. Subsequently, carbon dioxide gas enters the gas guide ring through the gas guide pipe. The closure of the first or second gas guide hole is adjusted according to the amount of calcium hydroxide slurry and the flow rate regulating mechanism. When the first gas guide hole is closed, carbon dioxide gas enters the gas guide ring through the gas guide pipe and flows out through the second gas guide hole. When the second gas guide hole is closed, carbon dioxide gas enters the gas guide ring through the gas guide pipe and flows out through the first gas guide hole. At this time, the spiral stirring blades below rotate with the moving components, stirring the carbon dioxide gas and calcium hydroxide slurry in the mixing chamber.

[0018] Because the flow rate of carbon dioxide gas entering the gas guide pipe is constant, and the opening size of the first gas guide hole is smaller than that of the second gas guide hole, the flow rate of carbon dioxide gas flowing out of the first gas guide hole will be greater than that flowing out of the second gas guide hole. When there is a large amount of calcium hydroxide slurry in the mixing chamber, the mixing of calcium hydroxide slurry and carbon dioxide gas will be more uniform, and the carbonation efficiency of calcium carbonate can be accelerated. Furthermore, when the carbon dioxide gas and calcium hydroxide slurry in the mixing chamber are being stirred, the calcium hydroxide slurry for the next reaction enters the calcium hydroxide slurry stirring chamber from the feed inlet above the reactor, and the spiral agitator above... The mixing blades perform a stirring operation; through the cooperation of the drive component and the moving component, the upper and lower spiral stirring blades are controlled to rotate at different speeds, so that the device can simultaneously and rapidly stir the unmixed calcium hydroxide slurry and fully mix the calcium hydroxide slurry with carbon dioxide gas under the same driving force, improving the practicality of the device; and through the flow rate adjustment mechanism, the outflow rate in the mixing chamber can be flexibly changed according to the amount of calcium hydroxide slurry while the carbon dioxide gas supply flow rate is constant, so that the calcium hydroxide slurry and carbon dioxide gas can be mixed and reacted more evenly, further improving the practicality of the device.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] In some embodiments, please refer to the accompanying drawings. Figures 1-6 A multi-compartment carbonization device includes a reactor 1, a multi-compartment synchronous mixing mechanism 2, a gas guide pipe 3, a gas guide ring 4, a flow rate regulating mechanism 5, and a baffle 6. The baffle 6 is fixedly installed in the middle of the reactor 1, dividing the reactor 1 into upper and lower compartments. A flow control valve is installed on the baffle 6 to control the connectivity between the upper and lower compartments. The upper part of the baffle 6 is a calcium hydroxide slurry stirring compartment, and the lower part of the baffle 6 is a mixing compartment. The upper end of the reactor 1 is equipped with a multi-compartment synchronous mixing mechanism 2 for stirring the materials in the calcium hydroxide slurry stirring compartment and the mixing compartment at different speeds.

[0031] The multi-compartment synchronous mixing mechanism 2 includes a drive assembly 23 for controlling the movement of the movable component 24, a movable component 24 for driving the spiral stirring blade 25 to rotate, and the spiral stirring blade 25. The drive assembly 23 is installed at the upper end of the reactor 1, and the movable component 24 is installed on the drive assembly 23. Two spiral stirring blades 25 are fixedly installed on the movable component 24.

[0032] The gas guide pipe 3 is fixedly installed on the lower side of the reactor 1; the gas guide ring 4 is fixedly installed on the inner bottom of the reactor 1; and the gas guide pipe 3 is connected to the gas guide ring 4; the outer end of the gas guide pipe 3 is connected to the gas pump; the gas guide ring 4 is provided with a plurality of first gas guide holes 41 and a plurality of second gas guide holes 42, the first gas guide holes 41 and the second gas guide holes 42 are staggered, and the first gas guide holes 41 and the second gas guide holes 42 are evenly distributed in a circumferential array on the gas guide ring 4; the opening size of the first gas guide hole 41 is smaller than the opening size of the second gas guide hole 42; the flow rate of carbon dioxide gas in the gas guide pipe 3 is constant.

[0033] A flow rate regulating mechanism 5 is installed on the gas guide ring 4 to control the closure of the first gas guide hole 41 or the second gas guide hole 42, thereby changing the flow rate of carbon dioxide gas; a calcium hydroxide slurry inlet is provided above the reactor 1.

[0034] In this invention, when the calcium carbonate carbonation process begins, calcium hydroxide slurry enters the calcium hydroxide slurry mixing chamber through the feed inlet above the reactor 1. Subsequently, the drive assembly 23 operates, driving the movable assembly 24 to move. The spiral stirring blade 25 moves along with the movable assembly 24. At this time, the upper spiral stirring blade 25 rotates to rapidly stir the calcium hydroxide slurry in the mixing chamber, quickly dispersing any precipitates and ensuring uniform mixing with carbon dioxide gas. After the calcium hydroxide slurry is fully stirred, the flow control valve opens the channel between the calcium hydroxide slurry mixing chamber and the mixing chamber. The fully stirred calcium hydroxide slurry then flows downwards into the mixing chamber. The passage between the calcium hydroxide slurry stirring chamber and the mixing chamber is closed; then, carbon dioxide gas enters the gas guide ring 4 through the gas guide pipe 3. Subsequently, the closure of the first gas guide hole 41 or the second gas guide hole 42 is changed according to the amount of calcium hydroxide slurry and the flow rate adjustment mechanism 5. When the first gas guide hole 41 is closed, carbon dioxide gas enters the gas guide ring 4 through the gas guide pipe 3 and flows out through the second gas guide hole 42; when the second gas guide hole 42 is closed, carbon dioxide gas enters the gas guide ring 4 through the gas guide pipe 3 and flows out through the first gas guide hole 41. At this time, the spiral stirring blade 25 below rotates together with the movable component 24 to stir the carbon dioxide gas and calcium hydroxide slurry in the mixing chamber.

[0035] Because the flow rate of carbon dioxide gas entering the gas guide pipe 3 is constant, and the opening size of the first gas guide hole 41 is smaller than that of the second gas guide hole 42, the flow rate of carbon dioxide gas flowing out of the first gas guide hole 41 will be greater than that flowing out of the second gas guide hole 42. When there is a large amount of calcium hydroxide slurry in the mixing chamber, the mixing of calcium hydroxide slurry and carbon dioxide gas will be more uniform, and the carbonation efficiency of calcium carbonate can be accelerated. Furthermore, when the carbon dioxide gas and calcium hydroxide slurry in the mixing chamber are being stirred, the calcium hydroxide slurry for the next reaction enters the calcium hydroxide slurry stirring chamber from the feed inlet above the reactor 1, and the spiral above... The stirring blades 25 perform a stirring operation; through the cooperation of the drive assembly 23 and the movable assembly 24, the upper and lower spiral stirring blades 25 are controlled to rotate at different speeds, so that the device can simultaneously and rapidly stir the unmixed calcium hydroxide slurry and fully mix the calcium hydroxide slurry with carbon dioxide gas under the same driving force, thus improving the practicality of the device; and through the flow rate adjustment mechanism 5, the outflow rate in the mixing chamber can be flexibly changed according to the amount of calcium hydroxide slurry while the carbon dioxide gas supply flow rate is constant, so that the calcium hydroxide slurry and carbon dioxide gas can be mixed and reacted more evenly, further improving the practicality of the device;

[0036] like Figures 1-3 As shown, the drive assembly 23 includes a support frame 231, a drive pinion 232, a drive gear 233, and a motor 234. The support frame 231 is fixedly installed on the upper end of the reactor 1, and the motor 234 is fixedly installed on the upper right side of the support frame 231. The drive pinion 232 is rotatably installed on the inner top right side of the support frame 231. The drive gear 233 is rotatably installed on the inner bottom right side of the support frame 231. The output end of the motor 234 is fixedly connected to the drive pinion 232 and the drive gear 233. Both the drive pinion 232 and the drive gear 233 are connected to the movable assembly 24.

[0037] like Figures 1-3As shown, the movable component 24 includes a driven pinion 241, a driven gear 242, a first rotating shaft 243, and a second rotating shaft 244. The upper end of the first rotating shaft 243 is rotatably mounted on the bottom left side of the support frame 231, and the lower end of the first rotating shaft 243 is rotatably mounted on the middle of the baffle 6. The second rotating shaft 244 is disposed inside the first rotating shaft 243 and rotatably connected to the first rotating shaft 243; the upper end of the second rotating shaft 244 is rotatably mounted on the top left side of the support frame 231. The lower end of the first rotating shaft 243 is rotatably mounted on the inner bottom of the reactor 1; a driven pinion 241 is fixedly mounted on the upper end of the first rotating shaft 243; a driven large gear 242 is fixedly mounted on the upper end of the second rotating shaft 244; the driving pinion 232 is meshed with the driven large gear 242; the driving large gear 233 is meshed with the driven pinion 241; a spiral stirring blade 25 is fixedly mounted on the outer end of the first rotating shaft 243; a spiral stirring blade 25 is also fixedly mounted on the lower part of the outer end of the second rotating shaft 244.

[0038] In this invention, the motor 234 controls the simultaneous rotation of the small drive gear 232 and the large drive gear 233. The rotation of the small drive gear 232 drives the driven large gear 242 to rotate. Since the small drive gear 232 is smaller than the driven large gear 242, the driven large gear 242 drives the second rotating shaft 244 to rotate at a reduced speed. The large drive gear 233 drives the driven small gear 241 to rotate. Since the large drive gear 233 is larger than the driven small gear 241, the driven small gear 241 drives the first rotating shaft 243 to rotate at an accelerated speed. At this time, the rotation speed of the second rotating shaft 244 is less than the rotation speed of the first rotating shaft 243. The operation of the first rotating shaft 243 drives the spiral stirring blade 25 connected to the first rotating shaft 243 to rotate, which rapidly stirs and disperses the calcium hydroxide slurry in the calcium hydroxide slurry mixing chamber. The operation of the second rotating shaft 244 drives the spiral stirring blade 25 connected to the second rotating shaft 244 to rotate, which uniformly stirs and mixes the calcium hydroxide slurry and carbon dioxide gas in the mixing chamber.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, the flow rate regulating mechanism 5 includes a sliding ring 51, a third air guide hole 52, an inner magnetic block 53, an outer magnetic block 54, a limiting slide rail 55, and a limiting plate 56. The sliding ring 51 is rotatably connected to the outer end of the air guide ring 4, and a plurality of third air guide holes 52 are provided on the sliding ring 51. The third air guide holes 52 are evenly distributed in a circumferential array on the sliding ring 51 at equal intervals. The opening size of the third air guide holes 52 is the same as the opening size of the second air guide holes 42.

[0040] An inner magnetic block 53 is fixedly installed on the sliding ring 51; a limiting slide rail 55 is fixedly installed below the outer end of the reactor 1, and limiting plates 56 are fixedly installed at the left and right ends of the limiting slide rail 55; an outer magnetic block 54 is limited and slidably connected to the limiting slide rail 55; the inner magnetic block 53 and the outer magnetic block 54 are attracted and connected to each other.

[0041] Furthermore, the shell, gas guide pipe 3, and gas guide ring 4 of the reactor 1 are all non-magnetic;

[0042] In this invention, when it is necessary to increase the flow rate of carbon dioxide gas, the operator pulls the outer magnetic block 54 along the limiting slide rail 55. At this time, the outer magnetic block 54 will attract the inner magnetic block 53 to drive the sliding ring 51 to rotate around the gas guide ring 4, so that the third gas guide hole 52 on the sliding ring 51 is aligned with the first gas guide hole 41. At this time, the second gas guide hole 42 is blocked by the sliding ring 51, and the carbon dioxide gas can only flow out through the first gas guide hole 41. Similarly, when it is necessary to decrease the flow rate of carbon dioxide gas, the third gas guide hole 52 is aligned with the second gas guide hole 42. At this time, the first gas guide hole 41 is blocked by the sliding ring 51, and the carbon dioxide gas can only flow out through the second gas guide hole 42.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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 will 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.
