This affects the efficiency of the pretreatment of lithium carbonate grading and purification of multi-component solid waste, and thus affects the overall efficiency of lithium carbonate grading and purification of multi-component solid waste.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a first crushing mechanism, with the bottom of the first variable frequency motor fixed to the bottom of the crushing tank, and the top of its output shaft passing through the crushing tank and fixed to the bottom of the support frame. Stable transmission is achieved through the power provided by the first variable frequency motor. The support frame is fixed to the inner wall of the fixed frame, and the surface of the fixed frame is in movable contact with the inner wall of the crushing tank, ensuring that the fixed frame rotates synchronously with the output shaft of the first variable frequency motor. Several first crushing blades are fixed to the surface of the fixed frame.

By controlling the second variable frequency motor to rotate counterclockwise and staggered with the first crushing blades, this reverse rotation and staggered layout can significantly increase the contact area with multi-component solid waste, improve crushing efficiency and crushing uniformity. At the same time, when the tank lid is raised or lowered, the rotating rod and the second crushing blades can move with the tank lid. With the limiting of the insert block and insert frame, the stable operation of the second variable frequency motor is ensured, further optimizing the crushing effect. This lays a good pretreatment foundation for the overall process of lithium carbonate graded purification of multi-component solid waste and improves the overall efficiency of lithium carbonate graded purification of multi-component solid waste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A lithium carbonate grading and purification device suitable for multi-component solid waste includes a crushing tank 1, a first crushing mechanism 8 is provided inside the crushing tank 1, a tank cover 3 is provided on the top of the crushing tank 1, a second crushing mechanism 9 is provided inside the tank cover 3, and electric telescopic rods 5 are provided on both sides of the crushing tank 1. The first crushing mechanism 8 includes a fixed frame 801, a plurality of first crushing blades 802, a support frame 803, and a first variable frequency motor 804. The first crushing blades 802 are fixedly connected to the surface of the fixed frame 801, the support frame 803 is fixedly connected to the inner wall of the fixed frame 801, the surface of the fixed frame 801 is in movable contact with the inner wall of the crushing tank 1, the top of the first variable frequency motor 804 is fixedly connected to the bottom of the crushing tank 1, the top of the output shaft of the first variable frequency motor 804 passes through the crushing tank 1 and is fixedly connected to the bottom of the support frame 803, and the surface of the output shaft of the first variable frequency motor 804 is in movable contact with the interior of the crushing tank 1.

[0019] In this embodiment: the crushing tank 1 is stably supported by the support leg 10, the electric telescopic rod 5 is fixed by the support block 7, and the support frame 4 and the support block 13 cooperate to make the electric telescopic rod 5 drive the tank cover 3 to rise and fall. When discharging material, the external power supply and controller make the electric telescopic rod 5 raise the tank cover 3 by 10 centimeters. Then, the external rod-shaped tool is used to move the second crushing blade 902 and the first crushing blade 802 to be misaligned. Then, the tank cover 3 is raised again. After the multi-component solid waste in block and granular form is put into the crushing tank 1, the tank cover 3 is closed. Then, the first variable frequency motor 804 is started to rotate clockwise, driving the first crushing blade 802 to rotate. Then, the second variable frequency motor is started. Motor 901 rotates counterclockwise, driving the second crushing blade 902 to rotate. The two blades work together to quickly crush blocky and granular multi-component solid waste. Then, the cover 2 of the air inlet 15 and the valve 12 of the discharge pipe 11 are opened. The external extraction device extracts the material through the wear-resistant discharge pipe 11 and valve 12, completing the crushing. This solves the problem that the existing crushing structure for the pretreatment of lithium carbonate classification and purification of some multi-component solid waste only uses one set of blades, resulting in low crushing efficiency. This affects the efficiency of the pretreatment of lithium carbonate classification and purification of multi-component solid waste, and consequently affects the overall efficiency of lithium carbonate classification and purification of multi-component solid waste.

[0020] Specifically, such as Figure 4 As shown, the second crushing mechanism 9 includes a second variable frequency motor 901, several second crushing blades 902, and a rotating rod 903. The bottom of the second variable frequency motor 901 is fixedly connected to the top of the can lid 3. The bottom of the output shaft of the second variable frequency motor 901 passes through the can lid 3 and is fixedly connected to the top of the rotating rod 903. The surface of the output shaft of the second variable frequency motor 901 is in movable contact with the inside of the can lid 3. The second crushing blades 902 are fixedly connected to the surface of the rotating rod 903. The second crushing blades 902 and the first crushing blades 802 are staggered.

[0021] Specifically, such as Figure 5As shown, the top of the can lid 3 is provided with an air inlet 15, and the top of the air inlet 15 is provided with a cover 2, the surface of the cover 2 being threadedly connected to the inner wall of the air inlet 15.

[0022] Specifically, such as Figure 2 As shown, support blocks 7 are fixedly connected to both sides of the crushing tank 1, and the bottom of the electric telescopic rod 5 is fixedly connected to the top of the support blocks 7.

[0023] In this embodiment: the second variable frequency motor 901 drives the rotating rod 903 and the second crushing blade 902 to rotate counterclockwise. The second crushing blade 902 and the first crushing blade 802, which rotates clockwise, are staggered, which significantly improves the crushing efficiency and uniformity. The air inlet 15 cooperates with the threaded hole cover 2, which can easily open the hole cover 2 to avoid negative pressure hindering the discharge during material discharge. The support block 7 provides a stable installation base for the electric telescopic rod 5, ensuring that it does not deviate during operation and ensuring the stable lifting and lowering of the tank cover 3.

[0024] Specifically, such as Figure 2 and Figure 4 As shown, a support frame 4 is fixedly connected to the top of the can lid 3, and support blocks 13 are fixedly connected to both sides of the support frame 4. The top of the telescopic end of the electric telescopic rod 5 is fixedly connected to the bottom of the support block 13.

[0025] Specifically, such as Figure 2 and Figure 4 As shown, both sides of the can lid 3 are fixedly connected with insert blocks 14, and both sides of the crushing can 1 are fixedly connected with insert frames 6, with the insert blocks 14 movably inserted into the interior of the insert frames 6.

[0026] In this embodiment: the support frame 4 and the support block 13 cooperate to provide a reliable connection point for the extension and retraction end of the electric telescopic rod 5, so that the driving force is transmitted smoothly. With the help of the external synchronous controller, the extension and retraction ends of the two electric telescopic rods 5 are controlled simultaneously to ensure that the can lid 3 is raised and lowered synchronously. The insert block 14 is movably inserted into the insert frame 6, which can limit the can lid 3 when it is closed, so that the second frequency conversion motor 901 rotates more stably.

[0027] Specifically, such as Figure 1 As shown, a discharge pipe 11 is fixedly connected to the front side of the crushing tank 1, and a valve 12 is installed inside the discharge pipe 11.

[0028] Specifically, such as Figure 1 As shown, the bottom of the crushing tank 1 is fixedly connected with support legs 10. The support legs 10 are inclined and there are several support legs 10 evenly distributed at the bottom of the crushing tank 1.

[0029] In this embodiment: the discharge pipe 11 facilitates the discharge of crushed materials, the valve 12 can flexibly control the opening and closing of the discharge pipe 11, and the inclined and evenly distributed support legs 10 provide stable support for the crushing tank 1, effectively preventing the crushing tank 1 from shaking and tipping over during operation, and ensuring operational safety.

[0030] Working principle: First, the crushing tank 1 is stably supported by the outriggers 10. Several inclined outriggers 10 are evenly distributed at the bottom of the crushing tank 1, providing a stable support foundation and preventing the crushing tank 1 from shaking or tipping over during crushing operations. The support blocks 7 fixed on both sides of the crushing tank 1 provide installation points for the electric telescopic rod 5. The bottom of the electric telescopic rod 5 is fixedly connected to the top of the support block 7 to ensure stable installation of the electric telescopic rod 5. The support frame 4 fixed to the top of the tank cover 3 and the support blocks 13 fixed on both sides allow the top of the telescopic end of the electric telescopic rod 5 to be fixedly connected to the bottom of the support block 13. Thus, the lifting and lowering operation of the tank cover 3 is achieved by extending and retracting the electric telescopic rod 5. When it is necessary to put multiple sets of blocky and granular materials into the crushing tank 1... When sorting solid waste, first power is supplied to the electric telescopic rods 5 via an external power source. Then, the external controller simultaneously controls the telescopic ends of both electric telescopic rods 5 to rise. At this time, the can lid 3 moves upward under the action of the electric telescopic rods 5. When the can lid 3 is opened by 10 centimeters, it stops rising. At this point, because the second crushing blade 902 and the first crushing blade 802 are staggered with a gap, they will not come into contact. Next, an external rod-shaped tool is inserted into the crushing can 1 to move the second crushing blade 902 to a staggered position with the first crushing blade 802, to avoid collision between the first crushing blade 802 and the second crushing blade 902 when the can lid 3 is raised further. Then, the external controller continues to control the telescopic ends of the two electric telescopic rods 5 to extend upward until the can lid 3 is fully open. Open the container, and you can then put the multi-component solid waste in block and granular form into the crushing tank 1. Then, control the extension end of the electric telescopic rod 5 to descend, causing the tank cover 3 to close. The insert block 14 is then reinserted into the insert frame 6. Since the insert blocks 14 fixed on both sides of the tank cover 3 are movably inserted into the insert frames 6 fixed on both sides of the crushing tank 1, the cooperation between the insert blocks 14 and the insert frames 6 can limit the closing of the tank cover 3, making the rotation of the second variable frequency motor 901 more stable. Subsequently, control the first variable frequency motor 804 and the second variable frequency motor 901 to work. The first variable frequency motor 804 rotates clockwise, and the top of its output shaft passes through the crushing tank 1 and is fixedly connected to the bottom of the support frame 803. The support frame 803 is fixed to the inner wall of the fixed frame 801, and the surface of the fixed frame 801 is flush with the crushing tank 1. The inner wall is in contact with the fixed frame 801, and several first crushing blades 802 are fixedly connected to its surface. Therefore, when the first variable frequency motor 804 rotates, it drives the support frame 803, the fixed frame 801, and the first crushing blades 802 to rotate clockwise together. At the same time, the second variable frequency motor 901 rotates counterclockwise. The bottom of its output shaft passes through the tank cover 3 and is fixedly connected to the top of the rotating rod 903. Several second crushing blades 902 are fixedly connected to the surface of the rotating rod 903, and the second crushing blades 902 are staggered with the first crushing blades 802. Therefore, when the second variable frequency motor 901 rotates, it drives the rotating rod 903 and the second crushing blades 902 to rotate counterclockwise together. The clockwise rotating first crushing blades 802 and the counterclockwise rotating second crushing blades 902 cooperate with each other.The crushing tank 1 rapidly crushes lumpy and granular multi-component solid waste. The staggered blades ensure more thorough contact with the waste, improving crushing efficiency and effectiveness. After crushing, an air inlet 15 is provided at the top of the tank cover 3, with a threaded cap 2 connected to it. Opening the cap 2 allows the crushing tank 1 to communicate with the outside atmosphere, preventing negative pressure from forming inside and affecting extraction efficiency during subsequent material extraction. Simultaneously, the valve 12 installed inside the discharge pipe 11 on the front side of the crushing tank 1 is opened. Both the discharge pipe 11 and valve 12 are made of wear-resistant material to prevent excessive wear due to material friction during extraction, extending their service life. Then, an external extraction device is connected to the discharge pipe 11, using suction to remove the crushed multi-component solid waste. The material is extracted from the crushing tank 1, completing the crushing operation. The first crushing blade 802 and the second crushing blade 902 rotate in different directions to crush blocky and granular multi-component solid waste, improving the crushing efficiency and effect. This solves the problem of existing crushing structures for lithium carbonate fractionation and purification pretreatment of some multi-component solid waste, where crushing is only completed by one set of blades, resulting in low crushing efficiency and affecting the efficiency of lithium carbonate fractionation and purification pretreatment, thus impacting the overall efficiency of lithium carbonate fractionation and purification. It should be noted that the first variable frequency motor 804, the second variable frequency motor 901, and the electric telescopic rod 5 are all existing, published, and mature technologies, powered by an external power supply and controlled by an external controller. Furthermore, any content not described in detail in this specification is prior art known to those skilled in the art, and its basic mechanisms will not be elaborated here.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
