Description

Technical Field

[0001] This invention relates to the field of high-purity lithium carbonate preparation technology, and more specifically, to a reaction apparatus for preparing high-purity lithium carbonate. Background Technology

[0002] Lithium carbonate is a crystalline inorganic compound that can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solution. It is commonly used in the medical field to treat patients with depression. High-purity lithium carbonate is usually prepared using lepidolite as a raw material, and the preparation process requires the use of appropriate calcination reaction equipment.

[0003] When existing roasting reactors are in use, because the roasting device is in a static state, the lepidolite raw material will accumulate inside the device after the operator puts it in. Therefore, during the roasting process, the raw material at the bottom of the accumulation layer cannot be heated by the roasting device in time, which will affect the overall heating efficiency of the raw material. Furthermore, after roasting, the operator usually needs to manually pour out and collect the raw material in the roasting device. However, due to the large size of the roasting device, it is inconvenient for the operator to turn the device over to pour out and collect the raw material.

[0004] Therefore, based on the inventor's extensive experience in design, development, and actual manufacturing in the relevant industry over many years, the inventor has researched and improved the existing structure and its shortcomings, and provided a reaction device for preparing high-purity lithium carbonate, in order to achieve a faster efficiency in preparing high-purity lithium carbonate. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a reaction apparatus for preparing high-purity lithium carbonate. The present invention incorporates movable components. An operator adds raw materials through one end of the calcining furnace body. After addition, the feed cover and discharge cover are installed on the left and right sides of the calcining furnace body, respectively. Then, driven by an automatic feeding component, the entire calcining component is moved into the interior of the toothed rotating ring, and a locking block is installed inside the mounting groove, fixing the calcining furnace body to the toothed rotating ring. A first driving device then drives the rotating shaft to rotate, causing the rotating gear to rotate synchronously. Through meshing with the toothed rotating ring, the toothed rotating ring can be connected to the calcining furnace body installed inside, allowing for synchronous rotation. This improves the heating rate of the raw materials, and the operator can later rotate the locking block... The connecting rod can be quickly disassembled, facilitating the cleaning of the stirring blades and thus improving the practicality of the device. The invention features an automatic feeding assembly that lifts the entire roasting furnace body. A third drive device rotates the connecting shaft, allowing the connecting ring to flip along with the furnace body at a certain angle. This automates the unloading of raw materials, replacing manual feeding and further enhancing the device's practicality. Furthermore, the invention incorporates a collection assembly that aligns the flipped furnace body surface with the interior of the U-shaped trough, providing support and allowing the raw materials to fall along the guide plate into the finished product collection box. This facilitates the unified collection of roasted materials, improving the device's convenience and addressing the problems mentioned in the background section.

A rotating screw is fixedly installed on the surface of the hexagonal locking block. A flipping assembly is movably installed on the surface of the rotating screw.

[0010] In a preferred embodiment, the flipping assembly includes a movable column, a first fixed column fixedly installed on the left side of the top surface of the movable column, a second fixed column fixedly installed on the right side of the top surface of the movable column, an electrically operated telescopic rod fixedly installed inside the first fixed column, a lifting block fixedly installed at the top of the electrically operated telescopic rod, a third driving device fixedly installed on the surface of the lifting block, a connecting shaft fixedly installed on the surface of the third driving device, a sliding block fixedly installed on the side of the lifting block, and a rotating groove fixedly installed at one end of the connecting shaft.

[0011] In a preferred embodiment, the collection assembly includes a fixed box, the surface of which is fixedly connected to the side of the roasting device base. A finished product collection box is detachably installed inside the fixed box. A pull handle is fixedly installed on the surface of the finished product collection box.

A U-shaped groove is formed on the surface of the guide plate.

[0012] In a preferred embodiment, there are two snap-fit ​​blocks, the surfaces of the two snap-fit ​​blocks are respectively movably connected to the interior of two mounting slots, and the surface of the mounting ring is movably connected to the interior of the rotating slot.

[0013] In a preferred embodiment, the surface of the connecting rod is movably connected to the interior of the feed cover, and the surface of the roasting furnace body is movably connected to the interior of the U-shaped groove.

[0016] The technical effects and advantages of this invention are as follows:

[0017] This invention, through the installation of movable components, allows operators to add raw materials through one end of the roasting furnace body. After addition, the feed cover and discharge cover are installed on the left and right sides of the roasting furnace body, respectively. Then, driven by the automatic feeding component, the roasting component is moved into the interior of the toothed rotating ring, and the locking block is installed inside the mounting groove, fixing the roasting furnace body to the toothed rotating ring. The first driving device then drives the rotating shaft to rotate, causing the rotating gear to rotate synchronously. Through meshing with the toothed rotating ring, the toothed rotating ring connects to the roasting furnace body installed inside, allowing for synchronous rotation. Therefore, in conjunction with the stirring blades, it prevents the raw materials from accumulating inside the roasting furnace body, thus improving the heating rate of the raw materials. Furthermore, operators can quickly disassemble the connecting rod by rotating the locking pin, facilitating cleaning of the stirring blades, thereby improving the practicality of the device.

[0018] This invention features an automatic feeding assembly. After the raw material is roasted, a second drive device rotates the rotating end, causing the hexagonal locking block inside the rotating end to rotate synchronously. This allows the rotating screw to rotate inside the first fixed plate, enabling the moving column to move horizontally on the top surface of the roasting device base. This allows the mounting ring inside the connecting ring to move horizontally along with the roasting furnace body, disengaging the roasting furnace body from the toothed rotating ring. At this point, an electric telescopic rod extends, lifting the entire roasting furnace body. A third drive device then rotates the connecting shaft, causing the connecting ring and the roasting furnace body to rotate at a certain angle. This automated material unloading replaces manual feeding, significantly improving the device's practicality.

[0019] This invention, by setting up a collection component, fits the surface of the roasting furnace body after it has been flipped into contact with the inside of the U-shaped groove, thus providing a certain degree of support for the roasting furnace body. This allows the raw materials to fall along the surface of the guide plate and eventually into the interior of the finished product collection box, making it convenient for operators to collect the roasted raw materials in a unified manner, thereby improving the convenience of the device.

[0032] Among them, as attached Figure 7The collection component 5 includes a fixed box 51, the surface of which is fixedly connected to the side of the roasting device base 1.

[0033] The working principle of this invention is as follows: First, the operator adds the raw material through one end of the roasting furnace body 391. After adding the raw material, the feed cover 394 and the discharge cover 3910 are installed on the left and right sides of the roasting furnace body 391, respectively.
