Description

A continuous neutralization reaction device for pseudoboehmite Technical Field

[0001] This invention belongs to the field of boehmite production technology, and in particular relates to a continuous neutralization reaction device for boehmite. Background Technology

[0002] Boehmite is a transitional aluminum oxide with high specific surface area and large pore volume. Its wet form is a white colloidal substance, while its dry form is a white powder. It possesses a thixotropic gel structure and uniform pore size distribution, making it suitable as a desiccant, adsorbent, and catalyst and catalyst support in petrochemical, fertilizer, and waste gas industries.

[0003] Patent document CN219502684U discloses a reaction device for producing boehmite, which includes a carbonization tank and a storage tank. The storage tank is disposed on the carbonization tank and stores carbon dioxide and supplies carbon dioxide to the carbonization tank. It also includes an auxiliary box, a sealing plate and a driving mechanism. The auxiliary box is disposed on the outer wall of the storage tank and has multiple vent holes on the side of the auxiliary box near the carbonization tank.

[0004] In the aforementioned application, carbon dioxide enters the tank through a connecting pipe, and then sequentially passes through a vent, a connecting hole, an annular cavity, and an outlet. As the rotating shaft rotates, the central plate rotates as well, and the first and second side plates remain in contact with the inner wall of the tank. When carbon dioxide is ejected from the outlet, it rotates, thus supplying carbon dioxide into the tank. However, the carbon dioxide may become unevenly distributed within the storage tank over a long period, making it difficult to ensure continuous and stable delivery of carbon dioxide and inconvenient to control the concentration of delivered carbon dioxide. Therefore, improvements are needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a pseudo-boehmite continuous neutralization reaction apparatus, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a continuous neutralization reaction device for pseudo-boehmite, comprising a reaction vessel, wherein a feed pipe is connected through and fixedly to the top of the reaction vessel, a discharge pipe is connected through and fixedly to the bottom of the reaction vessel, a motor is fixedly installed on the top of the reaction vessel, and a rotating shaft is fixedly connected to the motor through its output shaft, the bottom of the rotating shaft penetrates the reaction vessel and extends into the interior of the reaction vessel, and at least one continuous conveying mechanism is provided on the surface of the reaction vessel;

[0007] The continuous conveying mechanism includes a bevel gear A, a support, a piston pump, a carbon dioxide storage tank, and a connecting rod. The bevel gear A is fixedly connected to the top surface of the rotating shaft. The support is fixedly connected to the top of the reactor. A rotating rod is rotatably connected through the side of the support. A turntable and a bevel gear B are fixedly connected to both sides of the rotating rod, respectively. The bevel gear B meshes perpendicularly with the bevel gear A. A connecting column A is fixedly connected to the side of the turntable away from the rotating rod. The piston pump and the carbon dioxide storage tank are both fixedly connected to the surface of the reactor. A piston rod is slidably connected inside the piston pump. The top of the piston rod extends out of the rear side of the piston pump and is fixedly connected to the connecting column B. The bottom of the piston rod is located inside the piston pump and is fixedly connected to a sealing slider. The two ends of the connecting rod are rotatably connected to the connecting column A and the connecting column B, respectively. An air intake pipe and an air delivery pipe are fixedly connected through the lower part of the piston pump. The end of the air intake pipe away from the piston pump is connected to the carbon dioxide storage tank.

[0008] A fixed pipe is fixedly connected to the bottom of the reactor. Multiple nozzles are rotatably connected to the rotating shaft inside the reactor. A self-sealing connection assembly is provided at the end of the gas supply pipe away from the piston pump.

[0009] According to the above technical solution, the self-sealing connection assembly includes an insertion head and two sets of inserts. The insertion head passes through and is fixedly connected to the end of the gas delivery pipe away from the piston pump. One set of inserts passes through and is fixedly connected to the side of the carbon dioxide storage tank, and the other set of inserts passes through and is fixedly connected to the side of the fixed pipe. The insertion head and the two sets of inserts are all provided with a communicating cavity. A spring telescopic rod is fixedly connected inside the communicating cavity, and a top head is fixedly connected to the telescopic end of the spring telescopic rod.

[0010] According to the above technical solution, a pressure gauge is installed on the top of the reactor, and multiple stirring blades are fixedly connected to the surface of the rotating shaft located inside the reactor. One-way valves are installed inside the suction pipe, the gas delivery pipe and the nozzle. The end of the suction pipe away from the piston pump is connected to the carbon dioxide storage tank through and fixedly connected. When a negative pressure is formed inside the piston pump, carbon dioxide will be drawn from the carbon dioxide storage tank through the suction pipe.

[0011] According to the above technical solution, in the initial state, the insert head is connected to a group of inserts near the carbon dioxide storage tank by bolts. When the carbon dioxide in the piston pump is squeezed in the initial state, it will be transported back to the carbon dioxide storage tank through the gas delivery pipe to form a circulating flow.

[0012] According to the above technical solution, the bottom of the rotating shaft is connected to the top of the fixed tube and rotates through it. The connecting cavity and the top head are both frustum-shaped. The fixed tube is provided with a rotation mechanism and at least one stirring mechanism. When the top head is squeezed and moves towards the inside of the connecting cavity, a gap is formed between the top head and the connecting cavity, allowing gas to flow.

[0013] According to the above technical solution, the self-rotating mechanism includes a vertical rod and bevel gears D corresponding to the nozzles. The bottom of the vertical rod is fixedly connected to the bottom of the fixed tube, the top of the vertical rod extends into the bottom cavity of the rotating shaft, and at least one bevel gear C is fixedly connected to the top surface of the vertical rod. The bevel gear D is fixedly connected to the surface of the corresponding nozzle.

[0014] According to the above technical solution, the bevel gear D meshes perpendicularly with the corresponding bevel gear C. When the bevel gear D revolves around the nozzle, it meshes with the bevel gear C and thus rotates.

[0015] According to the above technical solution, the agitation mechanism includes a crossbar, a slide cylinder, and a pressing rod. The crossbar passes through and is rotatably connected to the side of the fixed tube. Multiple agitating blades are fixedly connected to the surface of the crossbar. A driven gear is fixedly connected to the outer wall of the end of the crossbar that extends into the fixed tube. The slide cylinder is fixedly connected to the inner wall of the fixed tube. A slide rod is slidably connected inside the slide cylinder. An arc block is fixedly connected to the top of the slide rod. A toothed rod is fixedly connected to the bottom of the slide rod. A return spring is sleeved on the surface of the slide rod. The pressing rod is fixedly connected to the surface of the rotating shaft.

[0016] According to the above technical solution, the teeth on the rack mesh with the teeth on the driven gear, and the two ends of the return spring abut against the top of the slide cylinder and the bottom of the arc block, respectively. When the rack moves downward, its teeth mesh with the teeth on the driven gear, which will drive the driven gear to rotate. When the arc block drives the slide rod to move downward, the return spring will be compressed.

[0017] According to the above technical solution, the arc surface of the arc block is located on the movement trajectory of the extrusion rod. During the rotation of the extrusion rod following the rotating shaft, it will extrude the arc surface of the arc block, causing the arc block to move downward.

[0018] This invention provides a continuous neutralization reaction apparatus for pseudoboehmite. It has the following beneficial effects:

[0019] (1) The present invention, through the setting of a continuous conveying mechanism, enables the motor to drive the rotating shaft to rotate. During the stirring process, the rotating shaft drives the stirring blade to rotate. In addition, through the cooperation of structures such as bevel gear A, bevel gear B, and piston pump, the suction pipe draws carbon dioxide from the carbon dioxide storage tank and delivers it back to the carbon dioxide storage tank through the gas delivery pipe to form a circulation flow, so that the carbon dioxide concentration in the carbon dioxide storage tank is uniform. When the gas delivery pipe is connected to the fixed pipe through the self-sealing connection component, the carbon dioxide will be continuously and stably delivered to the fixed pipe and finally sprayed out into the reaction vessel by the nozzle to react with the sodium aluminate solution. The concentration of carbon dioxide delivered to the reaction vessel can be controlled according to the number of gas delivery pipes connected to the fixed pipe.

[0020] (2) The present invention uses a self-rotation mechanism to enable the motor to drive the rotating shaft to rotate. The rotating shaft drives the stirring blades to rotate during the stirring process. In addition, the nozzle rotates and sprays carbon dioxide into the reaction vessel through the cooperation of structures such as bevel gear C and bevel gear D. This allows the carbon dioxide to be distributed more evenly in the reaction vessel, resulting in a better reaction with the sodium aluminate solution.

[0021] (3) The present invention, through the setting of the stirring mechanism, enables the motor to drive the rotating shaft to rotate. The rotating shaft drives the stirring blade to rotate during the stirring process. In addition, the crossbar rotates back and forth through the cooperation of the extrusion rod, arc block, slide cylinder and other structures. The back and forth rotation of the crossbar will drive the stirring blade to stir the pseudo-boehmite crystals generated at the bottom of the reactor, so as to prevent some sodium aluminate solution from being mixed in and unable to react with carbon dioxide.

[0035] 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.

[0036] Please refer to Figures 1-10. One embodiment of the present invention is: a continuous neutralization reaction device for pseudo-boehmite, including a reactor 1. A feed pipe 2 is connected through and fixedly to the top of the reactor 1, and a discharge pipe 3 is connected through and fixedly to the bottom of the reactor 1. A motor 5 is fixedly installed on the top of the reactor 1. A rotating shaft 6 is fixedly connected to the motor 5 through its output shaft. The bottom of the rotating shaft 6 penetrates the reactor 1 and extends into the interior of the reactor 1. At least one continuous conveying mechanism 8 is provided on the surface of the reactor 1. The continuous conveying mechanism 8 includes a bevel gear A81, a support 82, a piston pump 86, a carbon dioxide storage tank 813, and a connecting rod 814. The bevel gear A81 is fixedly connected to the top surface of the rotating shaft 6. The support 82 is fixedly connected to the top of the reactor 1. A rotating rod 83 is rotatably connected through and to the side of the support 82. Turntable 84 and bevel gear B815 are fixedly connected to both sides of rod 83 respectively. Bevel gear B815 meshes perpendicularly with bevel gear A81. Connecting column A85 is fixedly connected to the side of turntable 84 away from rotating rod 83. Piston pump 86 and carbon dioxide storage tank 813 are both fixedly connected to the surface of reactor 1. Piston rod 87 is slidably connected inside piston pump 86. Connecting column B88 is fixedly connected to the top of piston rod 87 extending out of the rear side of piston pump 86. The bottom of piston rod 87 is located inside piston pump 86 and is fixedly connected to sealing slider. The two ends of connecting rod 814 are rotatably connected to connecting column A85 and connecting column B88 respectively. Suction pipe 89 and gas delivery pipe 810 are respectively passed through and fixedly connected to the lower part of piston pump 86. The end of suction pipe 89 away from piston pump 86 is connected to carbon dioxide storage tank 813.A fixed pipe 811 is connected through and fixedly to the bottom of the reactor 1. Multiple nozzles 812 are rotatably connected to the rotating shaft 6 inside the reactor 1. A pressure gauge 4 is installed at the top of the reactor 1. Multiple stirring blades 7 are fixedly connected to the surface of the rotating shaft 6 inside the reactor 1. One-way valves are installed inside the suction pipe 89, the delivery pipe 810, and the nozzles 812. When a negative pressure is formed in the piston pump 86, carbon dioxide is drawn from the carbon dioxide storage tank 813 through the suction pipe 89. A self-sealing connection assembly 9 is installed at the end of the delivery pipe 810 away from the piston pump 86. The self-sealing connection assembly 9 includes an insert head 91 and two sets of inserts 92. The insert head 91 is connected through and fixedly to the end of the delivery pipe 810 away from the piston pump 86. One set of inserts 92 is connected through and fixedly to the side of the carbon dioxide storage tank 813, and the other set of inserts 92 is connected through and fixedly to the fixed pipe. On the side of 811, the insert head 91 and the two sets of insert tubes 92 each have a connecting cavity 94. A spring telescopic rod 95 is fixedly connected inside the connecting cavity 94, and a top head 96 is fixedly connected to the telescopic end of the spring telescopic rod 95. In the initial state, the insert head 91 is connected to a set of insert tubes 92 near the carbon dioxide storage tank 813 by bolts. When the carbon dioxide in the piston pump 86 is squeezed in the initial state, it will be transported back to the carbon dioxide storage tank 813 through the gas delivery pipe 810 to form a circulation. The bottom of the rotating shaft 6 is connected to the top of the fixed pipe 811 through and rotatably. The connecting cavity 94 and the top head 96 are both frustum-shaped. The fixed pipe 811 is provided with a rotation mechanism 10 and at least one agitation mechanism 11. When the top head 96 is squeezed and moves towards the inside of the connecting cavity 94, a gap is formed between the top head 96 and the connecting cavity 94, allowing gas to flow.

[0037] In use, close the discharge pipe 3, and then feed the raw material sodium aluminate solution into the reactor 1 through the feed pipe 2. After closing the feed pipe 2, unscrew the bolts to separate the insert 91 from the insert 92 on the carbon dioxide storage tank 813. At this time, the spring telescopic rod 95 inside the insert 91 and the insert 92 on the carbon dioxide storage tank 813 will rebound. The rebound of the spring telescopic rod 95 will drive the top head 96 to move and seal the connecting cavity 94, preventing gas from flowing out. Then, insert the insert 91 into the insert 92 on the side of the fixed pipe 811 and tighten it with bolts. At this time, the two sets of top heads 96 will squeeze each other and move towards the inside of the connecting cavity 94. When the device is moved, the spring telescopic rod 95 is compressed, creating a gap between the top head 96 and the connecting cavity 94, allowing gas to flow. The number of insertion heads 91 connected to the side inserts 92 of the fixed tube 811 can be selected according to the concentration of carbon dioxide to be supplied to the reactor 1. The motor 5 is turned on, and its output shaft drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the bevel gear A81 to rotate, which in turn drives the bevel gear B815 to rotate. The rotation of the bevel gear B815 drives the rotating rod 83 to rotate, which in turn drives the turntable 84 to rotate. The rotation of the turntable 84, in turn, drives the connecting column A8... 5. The connection between connecting rod 814 and connecting column B88 forms a connecting rod that drives piston rod 87 to move up and down repeatedly. When piston rod 87 moves upward, it creates a negative pressure in piston pump 86, thereby drawing carbon dioxide from carbon dioxide storage tank 813 through suction pipe 89. When piston rod 87 moves downward, it compresses the carbon dioxide in piston pump 86, causing it to be transported to fixed pipe 811 through gas delivery pipe 810. Carbon dioxide not connected to fixed pipe 811 is transported back to carbon dioxide storage tank 813 through gas delivery pipe 810, forming a circulation. This ensures that the carbon dioxide storage tank 813... The idle carbon dioxide concentration is kept uniform, and then enters the cavity at the bottom of the rotating shaft 6 from the fixed pipe 811. Finally, it is sprayed into the reaction vessel 1 through the nozzle 812 to react with the raw material sodium aluminate solution. The rotation of the rotating shaft 6 also drives the stirring blades 7 to stir, so that the carbon dioxide and the raw material sodium aluminate solution are in uniform contact. Compared with the existing technology, the overall delivery of carbon dioxide is more continuous and stable. The concentration of carbon dioxide delivered to the reaction vessel 1 can be controlled according to the number of gas delivery pipes 810 and fixed pipes 811 connected. At the same time, it can also ensure that the carbon dioxide concentration in the idle carbon dioxide storage tank 813 remains uniform.

[0038] Please refer to Figures 1-10. Based on the above embodiments, in another embodiment of the present invention, the rotating mechanism 10 includes a vertical rod 101 and bevel gears D103 corresponding to the nozzles 812. The bottom of the vertical rod 101 is fixedly connected to the bottom of the fixed tube 811, and the top of the vertical rod 101 extends into the bottom cavity of the rotating shaft 6. At least one bevel gear C102 is fixedly connected to the top surface of the vertical rod 101, and the bevel gear D103 is fixedly connected to the surface of the corresponding nozzle 812. D103 meshes perpendicularly with the corresponding bevel gear C102. When bevel gear D103 revolves around the nozzle 812, it meshes with bevel gear C102 and thus rotates. The agitation mechanism 11 includes a crossbar 111, a slide cylinder 114, and a squeezing rod 119. The crossbar 111 passes through and is rotatably connected to the side of the fixed tube 811. Multiple agitator blades 112 are fixedly connected to the surface of the crossbar 111. A driven gear 113 is fixedly connected to the outer wall of the end of the crossbar 111 that extends into the fixed tube 811. The slide cylinder 114 is fixedly connected to the inner wall of the fixed tube 811. A slide rod 115 is slidably connected inside the slide cylinder 114. An arc block 116 is fixedly connected to the top of the slide rod 115, and a gear 117 is fixedly connected to the bottom of the slide rod 115. A return spring 118 is sleeved on the surface of the slide rod 115. A pressing rod 119 is fixedly connected to the surface of the rotating shaft 6. The teeth on the gear 117 mesh with the teeth on the driven gear 113. The two ends of the return spring 118 are respectively connected to the top of the slide cylinder 114 and the arc block 116. The bottom of block 116 abuts against each other. When the rack 117 moves downward, its teeth mesh with the teeth on the driven gear 113, which will drive the driven gear 113 to rotate. When the arc block 116 drives the slide bar 115 to move downward, the return spring 118 will be compressed. The pressing rod 119 is fixedly connected to the surface of the rotating shaft 6. The arc surface of the arc block 116 is located on the movement trajectory of the pressing rod 119. During the rotation of the pressing rod 119 with the rotating shaft 6, it will press against the arc surface of the arc block 116, causing the arc block 116 to move downward.

[0039] In operation, when motor 5 is turned on and drives shaft 6 to rotate, shaft 6 rotates, causing nozzle 812 to revolve and spray carbon dioxide. Bevel gear D103, following nozzle 812's revolution, meshes with bevel gear C102, causing it to rotate. This rotation of bevel gear D103 drives nozzle 812 to rotate. Simultaneously, the rotation of nozzle 812 sprays carbon dioxide into reactor 1, allowing for more even distribution of carbon dioxide within reactor 1, thus improving the reaction with the sodium aluminate solution. Meanwhile, as extrusion rod 119 rotates with shaft 6, it presses against the arc surface of arc block 116, causing arc block 116 to move downwards. This downward movement of arc block 116 drives slide rod 11... 5. When the slide bar 115 moves downward, the return spring 118 is compressed, and the downward movement of the slide bar 115 will drive the rack 117 to move downward. When the squeeze rod 119 leaves the arc block 116, the return spring 118 rebounds, causing the slide bar 115, the arc block 116 and the rack 117 to move upward to restore their original positions. During the up-and-down movement, the teeth of the rack 117 mesh with the teeth on the driven gear 113, causing the driven gear 113 to rotate back and forth. The back-and-forth rotation of the driven gear 113 will cause the crossbar 111 to rotate back and forth. The back-and-forth rotation of the crossbar 111 will cause the stirring blade 112 to stir the pseudo-boehmite crystals generated at the bottom of the reactor 1, preventing some sodium aluminate solution from being mixed in and unable to react with carbon dioxide.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
