[0036] Compared with the prior art, the beneficial effects of this utility model are:

[0037] In this type of calcination equipment for producing battery-grade lithium carbonate, after heating is complete and material needs to be discharged, the user activates the electric push rod, causing its output end to move backward. This removes the limitation on the mounting side plate, and the mounting column moves backward under the elastic force of the spring, abutting against the front end of the annular detection plate. The drive shaft drives the annular detection plate. When the positioning slot on the annular detection plate moves to the rear of the mounting column, the rear end of the mounting column is inserted into the positioning slot. At this time, the mounting side plate at the lower end of the mounting column moves backward, applying pressure to the pressure sensor. The pressure sensor transmits the collected pressure information to the controller. After detecting the transmitted pressure information, the controller sends a command to the motor, causing the motor to stop working. This limits the annular detection plate and the drive shaft, and simultaneously aligns the feed pipe and discharge pipe of the heating furnace with the feed assembly and discharge assembly, respectively.

[0038] This invention solves the problem in the prior art that when the positioning block is inserted into the inner side of the positioning hole for limiting, the drive motor is still in the starting state, which can easily lead to damage to the drive motor and other equipment.

[0050] like Figure 1-5As shown, this utility model embodiment provides a calcination equipment for the production of battery-grade lithium carbonate, including a heating furnace 5. The heating furnace 5 is installed on the right side of the mounting frame 1 through a drive mechanism 2. A feed pipe 4 is installed at the upper end of the heating furnace 5, and a discharge pipe 6 is installed at the lower end of the heating furnace 5. Switch valves are installed on both the feed pipe 4 and the discharge pipe 6.

[0051] The drive mechanism 2 includes a motor 201 and a drive shaft 203. The motor 201 is mounted on the upper inner side of the mounting frame 1 via a motor 201 bracket. The left end of the drive shaft 203 is fixedly connected to the right end of the output shaft of the motor 201. The right end of the drive shaft 203 passes through the mounting frame 1 and is connected to the heating furnace 5.

[0052] In this embodiment, a feeding component 3 and a discharging component 7 are also included. Both the feeding component 3 and the discharging component 7 are fixedly installed on the right end of the mounting frame 1. The feeding component 3 is located directly above the feeding pipe 4, and the discharging component 7 is located directly below the discharging pipe 6.

[0053] The feeding assembly 3, the discharging assembly 7, the heating furnace 5, the feeding pipe 4, and the discharging pipe 6 are all derived from the authorized patent with application number 202322963559.1, and are existing technologies.

[0054] When in use, lithium carbonate is introduced into the inner side of the heating furnace 5 through the feeding component 3. Then, the user starts the motor 201, which drives the heating furnace 5 to rotate through the drive shaft 203.

[0055] The drive mechanism 2 also includes a drive plate 204 and an annular plate 205. The drive plate 204 is fixedly installed on the right end of the drive shaft 203. There are two annular plates 205, which are symmetrically fixedly installed on the right end of the drive plate 204. Both annular plates 205 are fitted onto the heating furnace 5.

[0056] The rotating drive shaft 203 can drive the drive plate 204 to rotate, and the rotating drive plate 204 can drive the heating furnace 5 to rotate through two annular plates 205.

[0057] The drive mechanism 2 also includes a detection box 202, which is mounted on the drive shaft 203 and fixedly installed on the left end of the mounting bracket 1.

[0058] The drive mechanism 2 also includes an annular detection plate 206 and a positioning slot 214. The annular detection plate 206 is mounted on the drive shaft 203 and is located inside the detection box 202. The positioning slot 214 is located at the front end of the annular detection plate 206.

[0059] The drive mechanism 2 also includes a mounting cylinder 207 and a mounting post 208. The front end of the mounting cylinder 207 is fixedly connected to the front wall inside the detection box 202. The front end of the mounting post 208 is fixedly connected to the front wall inside the mounting cylinder 207 by a spring. The rear end of the mounting post 208 slides through the rear end of the mounting cylinder 207 and is inserted into the positioning slot 214.

[0060] The drive mechanism 2 also includes an upper L-shaped mounting plate 213, a lower L-shaped mounting plate 211, an electric push rod 209, and a mounting side plate 212. The front ends of the upper L-shaped mounting plate 213 and the lower L-shaped mounting plate 211 are fixedly connected to the front wall of the inner side of the detection box 202. The upper L-shaped mounting plate 213 and the lower L-shaped mounting plate 211 are symmetrically arranged on the upper and lower sides of the mounting cylinder 207. There are two electric push rods 209. The two electric push rods 209 are fixedly connected to the rear ends of the upper L-shaped mounting plate 213 and the lower L-shaped mounting plate 211, respectively. The output ends of the two electric push rods 209 pass through the upper L-shaped mounting plate 213 and the lower L-shaped mounting plate 211, respectively. There are two mounting side plates 212. The two mounting side plates 212 are symmetrically fixedly installed on the upper and lower ends of the mounting column 208. The two mounting side plates 212 are located inside the upper L-shaped mounting plate 213 and the lower L-shaped mounting plate 211, respectively.

[0061] The drive mechanism 2 also includes a pressure sensor 210 and a controller 215. The pressure sensor 210 is fixedly installed on the lower L-shaped mounting plate 211. The pressure sensor 210 is located between the lower L-shaped mounting plate 211 and the mounting side plate 212 located at the lower end of the mounting column 208. The controller 215 is fixedly installed on the mounting bracket 1. The pressure sensor 210 is electrically connected to the controller 215, and the controller 215 is electrically connected to the motor 201.

[0062] After heating is complete and unloading is required, the user activates the electric push rod 209, causing its output end to move backward. This removes the limiting effect on the mounting side plate 212, allowing the mounting post 208 to move backward under the spring force and abut against the front end of the annular detection plate 206. The drive shaft 203 drives the annular detection plate 206. When the positioning slot 214 on the annular detection plate 206 moves to the rear side of the mounting post 208, the rear end of the mounting post 208 is inserted into the positioning slot 214, at which point it is positioned on the mounting post 208. The mounting side plate 212 at the lower end of 08 moves backward to apply pressure to the pressure sensor 210. The pressure sensor 210 can transmit the collected pressure information to the controller 215. The controller 215 is an SC200 general-purpose controller. After the controller 215 detects the transmitted pressure information, it can send a command to the motor 201, and the motor 201 stops working, thereby limiting the ring detection plate 206 and the drive shaft 203, and at the same time aligning the feed pipe 4 and the discharge pipe 6 of the heating furnace 5 with the feed assembly 3 and the discharge assembly 7, respectively.

[0063] When continued use is required, the mounting post 208 can be moved forward and separated from the positioning slot 214 by activating the electric push rod 209 via the two mounting side plates 212.

[0064] The drive mechanism 2 also includes guide side grooves and guide side blocks. There are four guide side grooves, which are arranged in a ring array on the inner wall of the mounting cylinder 207. There are four guide side blocks, which are arranged in a ring array and fixed to the side end face of the mounting column 208. The guide side grooves and guide side blocks are both arranged in the front-back direction. The four guide side blocks are slidably connected to the four guide side grooves in the front-back direction.

[0065] The guide block can slide back and forth in the guide groove to guide the mounting post 208 and prevent the mounting post 208 from rotating axially, which would affect the smooth pressing of the pressure sensor 210 by the mounting side plate 212 located at the lower end of the mounting post 208.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
