Description
Technical Field
[0001] This utility model relates to a grinding machine, and more particularly to a grinding machine for producing lithium carbonate from lepidolite. Background Technology
[0002] Lithium mica is a lithium-containing layered silicate mineral and one of the important raw materials for lithium extraction. It usually occurs as flaky or scaly aggregates and is light gray, light green, or light purple in color. In the process of producing lithium carbonate, lithium mica mineral is added to a grinding mill for grinding.
[0003] Existing grinding mills are widely used in grinding technology, but they also have many problems. For example, after grinding lepidolite, large particles of material are easily left above the screen, which can cause product contamination in the long run, affecting the grinding effect and product quality.
[0004] Therefore, it is necessary to design a grinding mill for producing lithium carbonate from lepidolite. Utility Model Content
[0005] In order to overcome the shortcomings of existing grinding mills, which leave large particles of material on the screen after grinding lepidolite, and cause product contamination over time, thus affecting the grinding effect and product quality, the technical problem is to provide a grinding mill for producing lithium carbonate from lepidolite.
[0006] The technical implementation scheme of this utility model is as follows: A grinding mill for producing lithium carbonate from lepidolite includes a body, a first support frame, a control display screen, a second support frame, a first motor, a first corrugated toothed roller, a second corrugated toothed roller, a large gear, a support block, a slide bar, a screen, and a spring. The first support frame is fixedly connected to both the front and rear sides of the machine body. A control display screen is installed on the left side of the machine body. The second support frame is fixedly connected to the left side of the machine body, and the first motor is installed on the second support frame. The first motor is electrically connected to the control display screen. The output shaft of the first motor passes through the interior of the machine body and is rotatably connected to the machine body. A first corrugated toothed roller is connected to the output shaft of the first motor. The machine body includes a toothed roller and a second toothed roller rotatably connected inside. Large gears are fixedly connected to the left ends of both the first and second toothed rollers, and these two gears mesh with each other. Two symmetrical support blocks are fixedly connected to the front and rear sides of the machine body. A sliding rod is fixedly connected to the top of each support block. The two rear sliding rods are longer than the two front sliding rods. A strainer is slidably connected between the four sliding rods. Springs connect the strainer to the support blocks, and the two rear springs are longer than the two front springs. The machine body also includes a cleaning mechanism for cleaning large lithium mica materials from the strainer.
[0007] Furthermore, the cleaning mechanism includes a rotating rod, a pulley assembly, an eccentric wheel, a top block, a baffle, and a storage box. The rotating rod is rotatably connected to the left side of the machine body. The first motor is connected to the rotating rod via the pulley assembly. An eccentric wheel is fixedly connected to the right end of the rotating rod. A top block is fixedly connected to the right side of the eccentric wheel. The top block contacts and engages with the strainer. A baffle is slidably connected to the left side of the machine body and is located in front of the strainer. A storage box is slidably connected to the front side of the machine body and is located in front of the baffle.
[0008] Furthermore, it also includes a spraying mechanism. The spraying mechanism is installed on the machine body and includes a connecting pipe, a water pump, water pipes and nozzles. The connecting pipe is fixedly connected to the left side of the machine body, and a water pump is installed on the top of the connecting pipe. The water pump is electrically connected to the control display screen. Water pipes are fixedly connected between the connecting pipe and the front and rear sides of the machine body. Multiple nozzles are fixedly connected to the water pipes on the sides that are close to each other.
[0009] Furthermore, it also includes a third support frame, a second motor, a connecting rod, and a wire brush. The third support frame is fixedly connected to the right side of the machine body, and the second motor is installed on the third support frame. The second motor is electrically connected to the control display screen. The connecting rod is connected to the output shaft of the second motor. The machine body is rotatably connected to the connecting rod, and wire brushes are fixedly connected to both the front and rear sides of the connecting rod.
[0010] Furthermore, it also includes a sealed door, which is rotatably connected to the top of the machine body.
[0011] Furthermore, it also includes a storage bin, which is slidably connected to the bottom of the machine body.
[0012] This utility model has the following advantages: 1. By setting up a cleaning mechanism, the output shaft of the first motor rotates and drives the rotating rod to rotate through the pulley assembly. The eccentric wheel at the right end of the rotating rod rotates accordingly. The rotation of the eccentric wheel drives the top block to rotate, and the spring deforms. Under the action of the top block, the screen vibrates in an inclined manner. Large particles will slide forward to the baffle. Pulling the baffle to the left, the large particles, without the obstruction of the baffle, fall into the storage box for collection. This can achieve the cleaning of the screen surface, effectively solving the problem that after grinding lithium mica, large particles of material are easily left on the screen, which can easily cause product contamination and affect the grinding effect and product quality in the long term.
[0013] 2. This utility model incorporates a spraying mechanism. A water hose is installed at the inlet of a water pump. When the water pump is started, it draws water from the pool into a connecting pipe via the water hose. Once the connecting pipe is full, the water is transported to various nozzles through the water pipe. The nozzles spray water onto the inside of the machine body, making the internal cleaning more efficient and improving the grinding effect. The second motor is then started, and its output shaft rotates, causing the connecting rod to rotate. The rotating connecting rod then rotates the wire brush, cleaning the inner sidewalls of the machine body and brushing off lithium mica particles or dust adhering to the sidewalls, thus maintaining the cleanliness of the machine body.

[0022] Example: A grinding mill for producing lithium carbonate from lepidolite, such as... Figures 1-3 As shown, the machine includes a body 1, a first support frame 2, a control display screen 3, a second support frame 4, a first motor 5, a first corrugated toothed roller 6, a second corrugated toothed roller 7, a large gear 8, a support block 9, a slide bar 10, a mesh screen 11, and a spring 12. The first support frame 2 is welded to both the front and rear sides of the body 1. The control display screen 3 is mounted on the left side of the body 1. The second support frame 4 is welded to the left side of the body 1, and the first motor 5 is mounted on the second support frame 4. The first motor 5 is electrically connected to the control display screen 3. The output shaft of the first motor 5 passes through the interior of the body 1 and is rotatably connected to the body 1. The first corrugated toothed roller 6 is connected to the output shaft of the first motor 5. The second corrugated toothed roller 7 is rotatably connected inside the body 1. The toothed roller 7, the first corrugated toothed roller 6, and the second corrugated toothed roller 7 are all welded with large gears 8 on their left ends. The two large gears 8 mesh with each other. Inside the machine body 1, there are two symmetrical support blocks 9 welded on the front and rear sides. Each support block 9 is welded with a slide rod 10 on its top. The length of the two slide rods 10 on the rear side is longer than that of the two slide rods 10 on the front side. A strainer 11 is slidably connected between the four slide rods 10. Springs 12 are connected between the strainer 11 and the support blocks 9. The length of the two springs 12 on the rear side is longer than that of the two springs 12 on the front side, so that the strainer 11 is in an inclined state. It also includes a cleaning mechanism. The machine body 1 is equipped with a cleaning mechanism for cleaning the large lithium mica material on the strainer 11.
[0023] like Figures 1-4 As shown, the cleaning mechanism includes a rotating rod 13, a pulley assembly 14, an eccentric wheel 15, a top block 16, a baffle 17, and a storage box 18. The rotating rod 13 is rotatably connected to the left side of the machine body 1. The first motor 5 is connected to the rotating rod 13 via the pulley assembly 14. The eccentric wheel 15 is welded to the right end of the rotating rod 13. The top block 16 is fixedly connected to the right side of the eccentric wheel 15. The top block 16 is in contact with the strainer 11. The baffle 17 is slidably connected to the left side of the machine body 1. The baffle 17 is located in front of the strainer 11. The storage box 18 is slidably connected to the front side of the machine body 1. The storage box 18 is located in front of the baffle 17.
[0024] like Figure 1 , Figure 2 and Figure 5As shown, it also includes a spraying mechanism. The spraying mechanism is installed on the machine body 1. The spraying mechanism includes a connecting pipe 19, a water pump 20, a water pipe 21, and a nozzle 22. The connecting pipe 19 is welded to the left side of the machine body 1. The water pump 20 is installed on the top of the connecting pipe 19. The water pump 20 is electrically connected to the control display screen 3. The connecting pipe 19 is fixedly connected to the front and rear sides of the machine body 1. Five nozzles 22 are fixedly connected to the sides of the water pipes 21 that are close to each other, which makes the internal cleaning of the machine body 1 more efficient and helps to improve the grinding effect.
[0025] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a third support frame 23, a second motor 24, a connecting rod 25, and a wire brush 26. The third support frame 23 is welded to the right side of the machine body 1. The second motor 24 is installed on the third support frame 23. The second motor 24 is electrically connected to the control display screen 3. The connecting rod 25 is connected to the output shaft of the second motor 24. The machine body 1 is rotatably connected to the connecting rod 25. Wire brushes 26 are welded to both the front and rear sides of the connecting rod 25 to brush off the lithium mica particles or dust adhering to the side wall of the machine body 1, keeping the inside of the machine body 1 clean.
[0026] like Figure 1 As shown, it also includes a sealing door 27 and a storage box 28. The sealing door 27 is rotatably connected to the top of the machine body 1 to prevent dust from escaping and to prevent external debris from entering the machine body 1 and affecting the grinding effect. The storage box 28 is slidably connected to the bottom of the machine body 1.
[0027] When grinding lepidolite minerals is required, the operator first turns the sealing door 27 to open the machine body 1, pours the lepidolite to be ground into the machine body 1, and then turns the sealing door 27 to close the machine body 1 to prevent dust from escaping and to prevent external debris from entering the machine body 1 and affecting the grinding effect. Next, the operator starts the first motor 5 via the control display screen 3. The output shaft of the first motor 5 rotates, driving the first corrugated toothed roller 6 to rotate. The rotation of the first corrugated toothed roller 6, through two meshing large gears 8, drives the second corrugated toothed roller 7 to rotate in the opposite direction, causing the lepidolite to be ground to pass through the first corrugated toothed roller 6 and... The second corrugated toothed roller 7 grinds and crushes the lithium mica particles into small particles, which fall onto the screen 11. The output shaft of the first motor 5 rotates, driving the rotating rod 13 to rotate via the pulley assembly 14. The eccentric wheel 15 at the right end of the rotating rod 13 rotates accordingly. The rotation of the eccentric wheel 15 drives the top block 16 to rotate. When the top block 16 is in a vertical position below the eccentric wheel 15, it will press down on the screen 11. The screen 11 moves downward on the slide rod 10, and the spring 12 is compressed. When the top block 16 is no longer in a vertical position below the eccentric wheel 15, the screen 11 detaches from the top block 16. The pressure causes the slide bar 10 to move upwards, and the spring 12 returns to its original position. This causes the screen 11 to vibrate continuously at an angle under the action of the top block 16. Particles of the correct size fall through the screen 11 into the storage bin 28 below the machine body 1 for easy collection and subsequent processing. Larger particles remain on the screen 11. This process not only speeds up the passage of particles of the correct size through the screen 11 but also prevents it from clogging. When there are many large particles on the screen 11, the vibration causes them to slide forward to the baffle 17 and gradually accumulate, preventing them from accumulating. Particles clog the screen 11, affecting subsequent screening. After grinding, turn off the first motor 5, pull the baffle 17 to the left, and the large particles, no longer blocked by the baffle 17, fall into the storage box 18 for collection. Push the baffle 17 to the right to reset it, thus cleaning the surface of the screen 11. Subsequently, the storage box 18 can be pulled out to the left to pour the large particles inside back into the machine body 1 for grinding and then reset. Finally, the storage box 28 can be pulled out to the left to process the ground lepidolite particles in the storage box 28 and then reset. In this way, the grinding and processing of lepidolite mineral can be achieved.
[0028] When cleaning the inside of the machine body 1 is required, a water hose is installed at the inlet of the water pump 20. The water pump 20 is started via the control display screen 3. The water pump 20 draws water from the pool into the connecting pipe 19 through the water hose. When the connecting pipe 19 is full, the water is delivered to each nozzle 22 through the water pipe 21. The nozzles 22 spray water onto the inside of the machine body 1, making the cleaning of the inside of the machine body 1 more efficient and helping to improve the grinding effect. The output shaft of the second motor 24 is started by the control display screen 3 to rotate, which drives the connecting rod 25 to rotate. The rotation of the connecting rod 25 drives the wire brush 26 to rotate, cleaning the inner side wall of the machine body 1 and brushing off the lithium mica particles or dust attached to the side wall of the machine body 1, keeping the inside of the machine body 1 clean. During the cleaning process, impurities and sewage fall into the storage tank 28 through the machine body 1. After cleaning is completed, the air pump and the second motor 24 are turned off, and the impurities and sewage inside the storage tank 28 are treated, thus completing the internal cleaning of the machine body.
