Description

Technical Field

[0001] This utility model belongs to the field of lithium carbonate production technology, and specifically relates to a lithium carbonate centrifuge device. Background Technology

[0002] Lithium carbonate is a common inorganic lithium salt, appearing as a colorless monoclinic crystal or a white powder. Its molecular weight is 73.891. It is slightly soluble in water and dilute acids, but insoluble in ethanol and acetone. Lithium carbonate centrifuges are devices used to separate lithium carbonate from liquids, playing a crucial role in the lithium carbonate production process. Lithium carbonate centrifuges primarily separate lithium carbonate from liquids through centrifugal force. During centrifugation, due to centrifugal force, the solid is thrown towards the outer wall of the centrifuge, while the liquid flows towards the center, thus achieving solid-liquid separation.

[0003] Announcement No. "CN221638459U" discloses a lithium carbonate centrifuge device, including an outer cylinder with a detachable cover fixedly connected to its upper end. A centrifuge cylinder is located inside the outer cylinder, with several small holes. A first bevel gear is fixedly connected to the upper end of the centrifuge cylinder, and a feed pipe is fixedly connected to one side of the upper end of the first bevel gear. A disc is fixedly connected to the outer wall of the feed pipe and is rotatably connected to the cover. A feed valve is fixedly connected to the feed pipe, located above the disc. An outlet is fixedly connected to the lower center of the centrifuge cylinder. This invention employs an outlet, a dispersing plate, a disc, a water guide groove, and a rod, allowing the lithium carbonate to be dispersed by the dispersing plate during centrifugation. This not only improves centrifugation efficiency but also prevents the lithium carbonate from rotating with the centrifuge cylinder, enabling better centrifugation treatment. Furthermore, the water guide groove, rod, and outlet allow the water guide groove to be removed for convenient lithium carbonate discharge, making it easy to use.

[0004] While the aforementioned utility model allows lithium carbonate to be dispersed by the dispersing plate during centrifugation, improving centrifugation efficiency and preventing lithium carbonate from rotating with the centrifuge drum, thus enabling better centrifugation processing, and with the water guide groove, insert rod, and discharge port, the water guide groove can be removed for convenient lithium carbonate discharge and ease of use, it is inconvenient to remove the centrifuge drum from the inside of the outer drum. Lithium carbonate will adhere to the inner wall of the centrifuge drum during centrifugation, making it difficult to thoroughly clean the inside. The residue accumulated over time may affect the normal operation of the equipment and even the product quality. Moreover, different batches of lithium carbonate or production needs may require centrifuge drums of different specifications or materials. If the centrifuge drum cannot be disassembled, it is impossible to replace it with a centrifuge drum of different specifications or materials as needed, thus limiting the flexibility and adaptability of the equipment. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a lithium carbonate centrifuge device to solve the problems of inconvenience in removing the centrifuge cylinder from the inside of the outer cylinder, lithium carbonate adhering to the inner wall of the centrifuge cylinder during the centrifugation process, making it difficult to thoroughly clean the inside, and the residue accumulated over a long period of time may affect the normal operation of the equipment and even affect the product quality.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A lithium carbonate centrifuge device includes a base, an outer cylinder fixedly connected to the upper end of the base, a fixed seat fixedly connected to the bottom end of the base, a rotating groove opened at the upper end of the fixed seat, a rotating seat rotatably connected inside the rotating groove, a rotating component installed between the rotating seat and the rotating groove, an installation groove opened at the upper end of the rotating seat, a centrifuge cylinder movably connected inside the installation groove, limit components symmetrically installed on the outer side wall of the outer cylinder, and a top cover movably connected to the upper end of the outer cylinder.

[0008] The rotating assembly includes a second drive motor, a drive gear, a driven gear, and a connecting shaft. The second drive motor is installed at the bottom of the rotating groove. The drive gear is fixedly connected to the outer side of the output end of the second drive motor. The connecting shaft is rotatably connected to the center of the bottom of the rotating groove via a bearing. The other end of the connecting shaft is fixedly connected to the bottom of the rotating seat. The driven gear is fixedly connected to the outer wall of the connecting shaft. The driven gear meshes with the drive gear, which can remove lithium carbonate adhering to the inner wall of the centrifuge tube, thereby keeping the equipment clean and hygienic. Moreover, it can select the appropriate centrifuge tube type or specification according to the characteristics of the material, thereby optimizing the centrifugation effect.

[0009] In one embodiment, an annular sliding groove is formed on the inner wall of the rotating slot, and an annular sliding block is fixedly connected to the outer wall of the rotating seat. The annular sliding block matches the curvature of the annular sliding groove, and the annular sliding block and the annular sliding groove are slidably connected. This can effectively limit the shaking and offset of the rotating seat, thereby improving the motion stability of the rotating seat and helping to ensure the accuracy and reliability of the equipment during operation.

[0010] In one embodiment, positioning blocks are symmetrically fixedly connected to the bottom of the mounting groove, and positioning grooves are symmetrically opened at the bottom of the centrifuge cylinder. The positioning blocks and positioning grooves are plugged in, which can effectively fix the centrifuge cylinder on the rotating seat, prevent it from shaking or shifting during operation, help improve the overall stability of the centrifuge device, and ensure that the equipment can operate smoothly and efficiently.

[0011] In one embodiment, the limiting assembly includes a fixed column, a threaded hole, an adjusting bolt, a torsion block, and an arc-shaped limiting block. Fixed columns are symmetrically fixedly connected to the outer wall of the outer cylinder. One end of each fixed column has a threaded hole communicating with the interior of the outer cylinder. An adjusting bolt is threaded into the threaded hole. A torsion block is fixedly connected to the end of the adjusting bolt away from the centrifuge cylinder. The other end of the adjusting bolt is rotatably connected to the arc-shaped limiting block. An annular limiting groove is formed on the outer wall of the centrifuge cylinder. The annular limiting groove and the arc-shaped limiting block are interlocked. The arc-shaped limiting block slides within the annular limiting groove, ensuring the stability of the centrifuge cylinder during rotation and preventing vibration or displacement caused by various external forces and internal stresses. This helps improve the centrifugation effect and ensures stable operation of the equipment.

[0012] In one embodiment, a first drive motor is installed on the upper end of the top cover. The output end of the first drive motor passes through the top cover and is fixedly connected to a rotating column. The other end of the rotating column extends into the interior of the centrifuge cylinder. A stirring roller is symmetrically fixedly connected to the outer wall of the rotating column. This can significantly improve the mixing uniformity of the material in the centrifuge cylinder, which helps to ensure that lithium carbonate particles can be evenly distributed during the centrifugation process, thereby improving the centrifugation effect and product quality.

[0013] In one embodiment, a waste liquid tank is symmetrically slidably connected inside the base. The inside of the waste liquid tank is interconnected with the inside of the outer cylinder, which can collect the wastewater after centrifugation. By collecting and treating the wastewater, environmental pollution can be reduced and ecological balance can be protected.

[0014] In summary, the present invention has the following main advantages:

[0015] First, in this utility model, the centrifuge cylinder is placed inside the mounting groove of the rotating seat inside the outer cylinder, and the positioning block is inserted into the positioning groove. Then, the lithium carbonate material is placed inside the centrifuge cylinder, the top cover is fixed to the upper end of the outer cylinder, the second drive motor is started, and the drive gear is controlled to rotate. The drive gear drives the driven gear to rotate, thereby causing the connecting shaft to drive the rotating seat and the internal centrifuge cylinder to rotate, separating the lithium carbonate from the liquid. The separated liquid flows into the waste liquid tank below, which can remove the lithium carbonate adhering to the inner wall of the centrifuge cylinder, thereby keeping the equipment clean and hygienic. Moreover, the appropriate centrifuge cylinder type or specification can be selected according to the characteristics of the material, thereby optimizing the centrifugation effect.

[0016] Secondly, in this utility model, the centrifuge cylinder is placed inside the mounting groove of the rotating seat inside the outer cylinder, and the positioning block is inserted into the positioning groove. The torsion block is rotated, which drives the adjusting bolt to rotate, thereby causing the adjusting bolt to rotate with the threaded hole. The adjusting bolt drives the arc-shaped limiting block to move forward. The arc-shaped limiting block moves into the annular limiting groove opened on the outer wall of the centrifuge cylinder. When the centrifuge cylinder rotates, the arc-shaped limiting block slides and limits itself inside the annular limiting groove. This ensures the stability of the centrifuge cylinder during rotation and prevents the centrifuge cylinder from being affected by various external forces and internal stresses, which could lead to vibration or displacement. This helps to improve the centrifugation effect and thus ensures the stable operation of the equipment. Attached Figure Description
