Description

Technical Field

[0001] The present invention relates to the technical field of chemical equipment, in particular to a lithium bicarbonate pyrolysis device. Background Art

[0002] As a specialized chemical equipment, the core function of the lithium bicarbonate pyrolysis unit is to efficiently and safely promote the pyrolysis reaction of lithium bicarbonate. The unit incorporates carefully designed key components, including the pyrolysis kettle, heat source system, condenser, collection tank, and a series of precision pipelines, to ensure the stable operation of the entire pyrolysis process. The pyrolysis kettle, as the core container, can withstand extreme conditions of high temperature and high pressure, providing the necessary space for the full reaction of lithium bicarbonate. The heat source system, through precise regulation, provides a stable and appropriate amount of heat energy for the pyrolysis reaction. The condenser utilizes an efficient cooling mechanism to rapidly condense the high-temperature gases produced by the reaction into liquid or solid products, facilitating subsequent separation and collection.

[0003] The collection tank plays a crucial role in product collection and processing. It not only contains the lithium carbonate and other byproducts produced after pyrolysis, but also ensures their stability and purity. Given the significant deliquescent nature of lithium carbonate, the collection tank is typically pre-filled with a high-efficiency desiccant to effectively absorb any moisture that may enter, thereby maintaining the lithium carbonate's dry state and chemical stability.

[0004] However, traditional desiccants have limited adsorption efficiency and need to be replaced promptly once they reach saturation. This process is not only time-consuming and labor-intensive, but may also interrupt the production process and affect overall efficiency. Therefore, we propose a new lithium bicarbonate pyrolysis device. Summary of the Invention

There are several arc rods and semicircular arc rings, one of which is fixedly connected to a current-carrying wire that passes through the collection tank, and the semicircular arc rings and arc rods are staggered with each other.

[0014] Preferably, a controller is fixedly installed on the base between the pyrolysis kettle and the collection tank, and the controller is electrically connected to the temperature sensor and the fan.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention effectively solves the problem that traditional desiccant has limited adsorption efficiency during lithium bicarbonate pyrolysis by arranging a dehydration component, and once saturation is reached, it needs to be replaced in time. The dehydration component can continuously and efficiently remove the moisture on the surface of lithium carbonate by the synergistic effect of a blower, a multi-port connector, an air guide connector, a dehydration pipe and a heating element, without the need to frequently replace the desiccant, thereby significantly improving production efficiency. At the same time, the design of the dehydration component further enhances the dehydration effect, so that the moisture on the surface of lithium carbonate is rapidly evaporated, improving the dryness and quality of the product.

[0017] 2. The present invention achieves uniform heating of the collection tank's interior by providing curved rods and connected semicircular arc rings. The staggered arrangement of the semicircular arc rings and curved rods forms a highly efficient heating network, enabling the collection tank to quickly reach and maintain a desired temperature. This facilitates drying of the lithium carbonate within the tank, accelerating the evaporation of surface moisture. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figures 1 to 6 The lithium bicarbonate pyrolysis device includes a base 1, a pyrolysis kettle 2 is fixedly installed on the top of the base 1, a collecting mechanism 3 is provided on one side of the pyrolysis kettle 2, and the collecting mechanism 3 includes a collecting tank 31 and a dewatering component 32, wherein the collecting tank 31 receives the pyrolysis product in the pyrolysis kettle 2, and uses the dewatering component 32 to dewater the product.

[0036] See also Figures 2 to 6 The dewatering component 32 includes a fan 321 fixedly mounted on the base 1, a multi-port connector 322 fixedly mounted on the output end of the fan 321, an air guide connector 323 fixedly mounted on the air outlet end of the multi-port connector 322, a dewatering pipe 324 passing through the collection tank 31 fixedly mounted on the air outlet end of the air guide connector 323, and a heating element 325 fixedly mounted on the dewatering pipe 324.

[0037] Airflow is generated by fan 321 and distributed through multi-port connector 322. Air is then introduced into dewatering pipe 324 via air guide connector 323. Heating element 325 heats the airflow in dewatering pipe 324, converting it into hot air that blows over the surface of the lithium carbonate, rapidly evaporating moisture. This design improves product dryness, ensuring the continuity of the lithium bicarbonate pyrolysis process and ensuring product quality.

[0038] In some embodiments, the multi-port connector 322 includes a main pipe 3221 , a top end of which is fixedly mounted a plurality of branch pipes 3222 communicating with the inner cavity of the main pipe 3221 , and the plurality of branch pipes 3222 are evenly distributed on the main pipe 3221 in a circular shape.

[0039] In this embodiment, the multi-port connector 322 ensures that the airflow generated by the fan 321 is evenly distributed to each branch pipe 3222, and then evenly guided into the dewatering pipe 324 through the air guide connector 323. This design improves the uniform flow of air in the dewatering pipe, thereby enhancing the dewatering effect and ensuring the dryness and production efficiency of the lithium bicarbonate pyrolysis product.

[0040] In some embodiments, the air guide connector 323 includes a first connecting elbow 3231 , and a second connecting elbow 3232 communicating with the inner cavity of the first connecting elbow 3231 is fixedly installed at the air outlet end of the first connecting elbow 3231 .

[0041] In this embodiment, the outlet end of the first connecting elbow 3231 is continuously guided by the second connecting elbow 3232, ensuring that the airflow generated by the fan 321 can smoothly enter the multi-port connector 322 and be stably directed into the water removal pipe 324 after passing through the two-stage elbow. This design enhances the stability and guidance of the airflow.

[0042] In some embodiments, the heating element 325 includes a semicircular arc ring 3251, to which an arc rod 3252 is fixedly connected. There are several arc rods 3252 and several semicircular arc rings 3251, and one of the arc rods 3252 is fixedly connected with a current-carrying wire 3253 that passes through the collection tank 31, and the semicircular arc rings 3251 and the arc rods 3252 are staggered with each other.

[0043] In this embodiment, a heating network is formed by the staggered arrangement of semicircular arc rings 3251 and curved rods 3252. Current-carrying conductors 3253 supply power to the entire heating network, heating the gas as it passes through it. This design increases the heating area and improves heating efficiency, ensuring the required temperature for water removal during the lithium bicarbonate pyrolysis process. The staggered arrangement also enhances heating uniformity, preventing localized overheating that could lead to lithium carbonate decomposition.

[0044] See also Figure 5 The collecting tank 31 is fixedly mounted on the base 1; a plurality of temperature sensors 4 are fixedly mounted on the inner wall of the collecting tank 31, and the temperature sensors 4 are evenly distributed on the inner wall of the collecting tank 31 in a circular shape; a drainage pipe 5 communicating with the inner cavity of the collecting tank 31 is fixedly mounted on the collecting tank 31.

[0045] The collection tank 31 receives the pyrolysis products. A temperature sensor 4 on the inner wall monitors the temperature, and a drain pipe 5 removes moisture and impurities. The collection tank 31, its temperature sensor 4, and drain pipe 5 ensure product purity. The sensor monitors the temperature in real time and provides feedback to the controller to ensure precise control of the water removal process. The drain pipe effectively removes moisture and uncondensed gases, ensuring product quality.

[0046] See also Figures 1 to 4 A condensing mechanism 6 is fixedly installed on the top of the pyrolysis kettle 2. The condensing mechanism 6 includes an air guide pipe 61 fixedly installed at the center of the top of the pyrolysis kettle 2 and connected to the inner cavity of the pyrolysis kettle 2. A condenser 62 is fixedly installed on the gas outlet end of the air guide pipe 61. A liquid guide pipe 63 fixedly connected to the collecting tank 31 is fixedly installed on the output end of the condenser 62. The liquid guide pipe 63 is connected to the inner cavity of the collecting tank 31.

[0047] The steam generated by pyrolysis in the pyrolysis kettle 2 enters the condenser 62 through the gas conduit 61 and condenses into liquid, and then flows into the collection tank 31 through the liquid conduit 63. The condensation mechanism 6 realizes the rapid condensation of steam and the effective collection of liquid, ensuring the smooth transfer of pyrolysis products and the subsequent dehydration process.

[0048] See also Figure 2 A controller 7 is fixedly installed on the base 1 between the pyrolysis kettle 2 and the collecting tank 31 . The controller 7 is electrically connected to the temperature sensor 4 and the fan 321 .

[0049] Controller 7 receives real-time temperature data from temperature sensor 4 within collection tank 31 via an electrical connection and precisely regulates the operating state of fan 321 based on this data. This enables precise control of the operation of dewatering assembly 32, ensuring smooth dewatering while avoiding decomposition of lithium carbonate due to excessive temperatures, thereby ensuring the quality and production efficiency of the pyrolysis products.

[0050] When in use, first, the lithium bicarbonate solution is poured into the pyrolysis kettle 2. The pyrolysis kettle 2 serves as the core container for the pyrolysis reaction. Its internal heating system can accurately heat the solution. As the temperature gradually increases, the lithium bicarbonate solution begins to undergo a pyrolysis reaction, decomposing into lithium carbonate (Li2CO3), water (H2O), and carbon dioxide (CO2). During this process, the solution boils and vaporizes, producing a large amount of steam.

[0051] The steam then enters the condensing mechanism 6 through the air duct 61 at the top of the pyrolysis vessel 2. The core component of the condensing mechanism 6 is the condenser 62, which utilizes a highly efficient cooling mechanism to rapidly condense the steam. The steam liquefies into a liquid in the condenser 62 and is then directed through the liquid duct 63 into the collection tank 31. At this point, the collection tank 31 contains not only the condensed liquid product but also a certain amount of water and uncondensed carbon dioxide.

[0052] In order to discharge these impurities, the operator can open the drain pipe 5 on the collection tank 31 to allow water and carbon dioxide to be discharged naturally under the action of gravity. This step is very important for maintaining the purity of the product in the collection tank 31.

[0053] Yet, because lithium carbonate has significant deliquescent characteristic, even through drainage step, its surface still may be attached with trace moisture.In order to thoroughly remove these moistures, dewatering assembly 32 comes into play.

[0054] Under the control of controller 7, fan 321 and heater 325 are activated simultaneously. Fan 321 generates strong wind, which is evenly distributed to each branch pipe 3222 via multi-port connector 322. The circular distribution of branch pipes 3222 ensures uniform wind flow in water removal pipe 324, thereby improving water removal efficiency.

[0055] As the gas flows through the dewatering pipe 324, it is heated by the heating element 325. The heating element 325 consists of semicircular arc rings 3251 and curved rods 3252, which are interlaced to form a dense heating network. As the gas passes through these heating elements, its temperature rises rapidly, turning into a gentle hot air. This hot air blows directly over the lithium carbonate, using its temperature and fluidity to quickly evaporate the moisture adhering to the lithium carbonate surface.

[0056] At the same time, the semicircular arc ring 3251 and the arc rod 3252 will also heat the inner cavity of the collection tank 31, so that the collection tank 31 is at a specified temperature, which is convenient for drying the lithium carbonate and making the water on the surface of the lithium carbonate evaporate faster.

[0057] To ensure precise control of the dewatering process, multiple temperature sensors 4 are installed on the inner wall of the collection tank 31. These sensors monitor the temperature inside the collection tank 31 in real time and feed the data back to the controller 7. Based on the received data, the controller 7 precisely adjusts the operating conditions of the fan 321 and the heater 325 to ensure smooth dewatering and prevent lithium carbonate decomposition due to excessive temperatures.

[0058] In summary, this lithium bicarbonate pyrolysis unit achieves efficient and safe lithium bicarbonate pyrolysis and pure product collection through a series of precisely designed components and an efficient workflow. Its unique water removal component not only improves product dryness but also ensures the stability and sustainability of the entire production process.

[0059] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
