Description

Technical Field

[0001] This utility model relates to the field of lithium carbonate processing technology, specifically to a high-efficiency lithium carbonate drying machine. Background Technology

[0002] Lithium carbonate is a basic lithium salt, a colorless monoclinic crystal with a melting point of 720℃. It is soluble in water and dilute acids, but insoluble in ethanol and acetone. Its thermal stability is lower than that of carbonates of other elements in the same group of the periodic table. It does not deliquesce in air and can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solutions. Passing carbon dioxide into its aqueous solution converts it to an acidic salt. Heating releases carbon dioxide to form lithium carbonate. Boiling the aqueous solution causes hydrolysis. Lithium carbonate is widely used in glass ceramics, new energy vehicles, alloys, and pharmaceuticals. In recent years, the new energy industry has developed rapidly, most notably in the booming lithium battery industry. Most cathode materials such as lithium cobalt oxide, lithium nickel oxide, lithium nickel cobalt oxide, lithium iron phosphate, and lithium nickel cobalt manganese oxide are prepared using lithium carbonate as a raw material. The demand for lithium carbonate is increasing and its application areas are expanding. However, the purity requirements are also getting higher and higher. The production cost of industrial-grade lithium carbonate is low and the output is large. Therefore, it is the most effective way to prepare battery-grade lithium carbonate directly from industrial-grade lithium carbonate. In the production process, lithium carbonate generally needs to be washed with water, centrifuged, and dried to obtain the finished lithium carbonate product.

[0003] A search revealed that Chinese patent application number 202223531263.4 discloses a lithium carbonate production apparatus, relating to the field of lithium carbonate technology. The apparatus includes a conveyor platform, a drive structure on the upper surface of the conveyor platform, a drying device slidably connected to the inner side of the drive structure, and an inlet box. A top plate is installed on the top of the inlet box, an electric heating plate is fixedly installed on the inner wall of the inlet box, and four inlet tubes are provided on the inner side of the inlet box.

[0004] The above-mentioned patent has the following shortcomings: In the process of drying lithium carbonate, the stacked lithium carbonate is dried by an electric heating plate. Due to the uneven internal heat transfer caused by the accumulation of materials, the moisture is difficult to escape effectively from the deep layers of the material, resulting in incomplete drying.

[0005] Therefore, there is an urgent need for a highly efficient lithium carbonate drying machine to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a highly efficient lithium carbonate drying machine. It solves the problem that in the process of drying lithium carbonate, when using an electric heating plate to dry the accumulated lithium carbonate, uneven internal heat transfer due to material accumulation makes it difficult for moisture to effectively escape from the deep layers of the material, resulting in incomplete drying.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency lithium carbonate drying machine, including a drying tank, a separation plate rotatably connected inside the drying tank, a plurality of evenly distributed screening ports on the separation plate, a plurality of evenly distributed mixing blades rotatably connected above and below the separation plate, a servo motor fixedly connected to the drying tank, the output end of the servo motor fixedly connected to the separation plate, a drying component connected to the drying tank, and a material suction component connected to one side of the drying tank.

[0008] Preferably, the drying component includes a drying rack fixedly connected to the drying tank, a dryer fixedly connected inside the drying rack, and multiple evenly distributed air outlets below the dryer.

[0009] Preferably, the suction component includes a suction pump fixedly connected to one side of the drying tank, a corrugated pipe fixedly connected to the suction pump, and the corrugated pipe, the air pump, and the drying tank are connected in communication.

[0010] Preferably, a pair of exhaust pipes are fixedly connected to the drying tank, and the exhaust pipes are connected to the drying tank.

[0011] Preferably, it also includes a movable frame, and the drying tank is fixedly connected inside the movable frame.

[0012] Preferably, a feeding plate is fixedly connected inside the movable frame, the feeding plate is inclined, a feeding port is opened on the drying tank, a baffle is rotatably connected to the feeding port, a cylinder is rotatably connected to the feeding plate, and the output end of the cylinder is rotatably connected to the baffle.

[0013] This invention provides a highly efficient lithium carbonate drying machine. Compared with the prior art, it has the following advantages:

[0014] This high-efficiency lithium carbonate drying machine uses airflow to blow air through the lithium carbonate during the drying process, thereby improving the thoroughness of drying. Furthermore, the sieve openings allow for the separation of thoroughly dried lithium carbonate, further enhancing the drying effect. This solves the problem of incomplete drying caused by uneven internal heat transfer due to material accumulation when using electric heating plates to dry piled-up lithium carbonate, making it difficult for moisture to effectively escape from the deeper layers of the material.

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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a high-efficiency lithium carbonate drying machine, including a drying tank 100, a separation plate 101 rotatably connected inside the drying tank 100, a plurality of evenly distributed screening ports 104 on the separation plate 101, a plurality of evenly distributed mixing blades 102 rotatably connected above and below the separation plate 101, a servo motor 103 fixedly connected to the drying tank 100, the output end of the servo motor 103 fixedly connected to the separation plate 101, a drying component connected to the drying tank 100, and a suction component connected to one side of the drying tank 100. The dried lithium carbonate can be separated through the screening ports 104 on the separation plate 101, and the contact surface between the lithium carbonate and the hot air can be increased under the action of the mixing blades 102, thereby improving the drying effect.

[0022] Please see Figures 1 to 3 The present invention provides a technical solution: the drying component includes a drying rack 110 fixedly connected to the drying tank 100, a dryer 111 fixedly connected inside the drying rack 110, and a plurality of evenly distributed air outlets 112 opened below the dryer 111. Hot air can be blown out through the air outlets 112 opened on the dryer 111 to dry lithium carbonate, which is more convenient to use.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: the suction component includes a suction pump 120 fixedly connected to one side of the drying tank 100, and a bellows 121 fixedly connected to the suction pump 120. The bellows 121, the air pump and the drying tank 100 are connected. By starting the suction pump 120, suction force is generated to move the bellows 121 to the lithium carbonate, thereby transferring the lithium carbonate into the drying tank 100, which is beneficial to improving the convenience of use.

[0024] Please see Figures 1 to 2 This utility model provides a technical solution: a pair of exhaust pipes 122 are fixedly connected to the drying tank 100. The exhaust pipes 122 are connected to the drying tank 100. The filter device set inside the exhaust pipes 122 can filter harmful gases while emitting gas, making it more practical.

[0025] Please see Figures 1 to 3 The present invention provides a technical solution: it also includes a movable frame 130, and the drying tank 100 is fixedly connected inside the movable frame 130. The movable frame 130 can improve the convenience of moving the device.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a feeding plate 131 is fixedly connected inside the movable frame 130. The feeding plate 131 is inclined. A feeding port 132 is opened on the drying tank 100. A baffle 133 is rotatably connected to the feeding port 132. A cylinder 134 is rotatably connected to the feeding plate 131. The output end of the cylinder 134 is rotatably connected to the baffle 133. By starting the cylinder 134 to retract and extend, the baffle 133 can be pushed to deflect, thereby opening and sealing the feeding port 132, which is beneficial to improving work efficiency.

[0027] During operation (or use): First, start the suction pump 120 to transport lithium carbonate through the bellows 121 into the drying tank 100. After all the material is sucked in, start the dryer 111. Hot air is blown out from the air outlet 112 to evenly dry the lithium carbonate. During the drying process, the dried lithium carbonate falls from the sieve 104 into the spacer plate 101 to avoid over-drying. At the same time, the mixing blades 102 rotate under the wind power to continuously stir the lithium carbonate on the spacer plate 101, enhancing the contact between the hot air and the material and improving drying efficiency. The exhaust pipe 122 discharges the evaporated moisture in real time to ensure a stable drying environment. After drying is completed, turn off the dryer 111 to allow the lithium carbonate to dry. Lithium naturally settles, and then cylinder 134 retracts, pulling baffle 133 to deflect and open discharge port 132. The dried lithium carbonate is discharged along discharge plate 131. Next, servo motor 103 is started to drive separation plate 101 to rotate, using centrifugal force to remove residual material adhering to the inner wall of drying tank 100. At the same time, the rotating structure of separation plate 101 can assist in cleaning the tank wall and improve the self-cleaning ability of the equipment. This design not only optimizes the drying effect, but also enhances the convenience of operation and the degree of automation, making the entire drying process more efficient and reliable.
