When the feed hopper is blocked, the staff starts the motor 1, so that the output end of the motor 1 drives the telescopic rod to rotate, and the telescopic rod drives the support plate to rotate through the fixed ring and the reinforcing rod, so that the support plate drives the motor 2 to rotate ninety degrees clockwise, and then the staff starts the motor 2, so that the output end of the motor 2 drives the transmission rod to rotate, and the transmission rod drives the drill bit to rotate, and drives the support rod and the rotating rod to rotate at the same time, and then the staff starts the telescopic rod to retract, and the motor 2 drives the drill bit, the support rod and the rotating rod to rotate downward through the output end, and the drill bit, the support rod and the rotating rod can clear the blocked material and improve work efficiency.

[0004] However, the above technology will have the following disadvantages when used: when the above technology is used to dry lithium carbonate, gas will be generated and needs to be discharged to the outside. The gas has a certain temperature, and direct discharge to the outside will increase the working environment temperature of the staff. The above technology condenses the hot air into a layer of liquid through the external temperature difference, and the cooling effect is general. A large amount of waste heat will still be dissipated into the air. The staff working under high temperature is prone to dehydration, which is not conducive to protecting the personal health of the staff. In addition, when the lithium carbonate is drying, the dryer is connected to the feed pipe, the hollow tube, and the feed hopper. The feed hopper is connected to the outside, which will cause part of the temperature to overflow, which is not conducive to maintaining temperature stability during the drying work. Therefore, a drying device for lithium carbonate production is urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0036] Embodiment 1, as Figure 1 - Figure 5 As shown, the utility model provides a drying device for lithium carbonate production, comprising: a drying box 1, one end of which is provided with a pressure relief valve 10, and further comprising:

[0037] The heat insulation cover 7 is fixedly mounted on one end of the drying box 1 close to the pressure relief valve 10, and a plurality of heat dissipation fins 901 are fixedly mounted on one end of the heat insulation cover 7 away from the pressure relief valve 10;

[0038] Two heat sinks 9 are respectively fixedly mounted on both ends of the heat shield 7 where a plurality of heat sink fins 901 pass through. A rectangular through hole 701 is formed at one end of the heat shield 7 away from the plurality of heat sink fins 901.

[0039] A drainage block 702 is fixedly mounted on one end of the heat shield 7 close to the rectangular through hole 701, and a connecting pipe 703 is fixedly mounted on one end of the drainage block 702 away from the heat shield 7;

[0040] The water tank 8 is fixedly mounted on one end of the connecting pipe 703 away from the drainage block 702 , and a water pump 801 is fixedly mounted on one end of the water tank 8 away from the connecting pipe 703 .

[0041] In this embodiment, when in use, all the equipment used in the device is connected to the external power supply, the staff controls the drying box 1 to work, the internal temperature thereof rises, and the lithium carbonate material inside is dried. The high-pressure and high-temperature gas generated during the drying work is placed in the heat insulation cover 7 through the pressure relief valve 10 rows to prevent the temperature from being dissipated to the external working environment. The multiple heat dissipation fins 901 in the heat insulation cover 7 absorb the gas temperature and conduct it to the partial heat dissipation fins 901 and the heat dissipation plate 9 outside the external heat insulation cover 7. After cooling, the gas in the heat insulation cover 7 is condensed into liquid and flows into the drainage block 702 from the rectangular through hole 701 at the bottom of the heat insulation cover 7 under the action of gravity. The liquid in the drainage block 702 flows into the water tank 8 through the connecting pipe 703 and mixes with the original liquid in the water tank 8. The staff turns on the power supply system of the water pump 801 and the booster pump 802, and controls both to start working. The input end of the water pump 801 is at the bottom of the water tank 8. When the water pump 801 is working, its internal motor drives the impeller to rotate. This creates a pressure difference in the liquid in the water tank 8, making it easier to send the liquid into the booster pump 802 through the impeller. After the booster pump 802 works, the liquid is increased in volume and transported to the delivery pipe 803. The delivery pipe 803 transports the pressurized liquid to the two secondary water storage blocks 804. After the internal liquid of the secondary water storage blocks 804 and the delivery pipe 803 is filled, the water pressure reaches the pressure value of the multiple spray nozzles 805. The multiple spray nozzles 805 spray the liquid into atomized form onto the outer surfaces of the heat sink fins 901 and the heat sink 9, which is beneficial to evaporating and cooling the heat sink fins 901 and the heat sink 9, thereby quickly taking away the temperature of the two on the external body of the heat insulation cover 7, and then the heat sink fin 901 body located inside the heat insulation cover 7 continues to absorb the temperature of the gas inside the heat insulation cover 7, causing the gas to condense into liquid, further improving the cooling efficiency of the high-temperature and high-pressure gas at the pressure relief valve 10, and helping to avoid a large amount of waste heat from being dissipated into the air. The high-temperature and high-pressure gas condenses into liquid and enters the water tank 8 for reuse, which is beneficial to saving water resources.

[0042] Embodiment 2, as Figure 1 - Figure 5As shown, the pressure relief valve 10 is located inside the heat insulation cover 7, a booster pump 802 is fixedly installed at the output end of the water pump 801, a delivery pipe 803 is fixedly installed at the output end of the booster pump 802, two secondary water storage blocks 804 are fixedly installed at one end of the delivery pipe 803 away from the booster pump 802, and multiple spray nozzles 805 are fixedly installed at one end of the two secondary water storage blocks 804 close to the multiple heat dissipation fins 901, the end of the water tank 8 close to the booster pump 802 is fixedly installed at one end of the drying box 1, the end of the booster pump 802 away from the delivery pipe 803 is fixedly installed at one end of the water tank 8, and the outer surface of the delivery pipe 803 away from the booster pump 802 is fixedly installed At one end of the drying box 1, one end of the two secondary water storage blocks 804 away from the multiple spray nozzles 805 is fixedly installed at one end of the drying box 1, and a feed hopper 2 is fixedly installed at the end of the drying box 1 away from the heat insulation cover 7. A slide groove 3 is provided at the end of the feed hopper 2 close to the drying box 1, and a baffle plate 4 is slidably installed on the inner surface of the slide groove 3. A threaded rod 6 is threadedly installed at one end of the baffle plate 4 away from the center of the feed hopper 2. Both ends of the threaded rod 6 away from the baffle plate 4 are installed at one end of the feed hopper 2 through bearings, and a motor 5 is fixedly installed at one end of the feed hopper 2 close to the threaded rod 6, and the output end of the motor 5 is coaxially fixedly connected with the end of the threaded rod 6 that passes through the feed hopper 2.

[0043] In this embodiment, when in use, after the material in the feed hopper 2 enters the interior of the drying box 1, the staff turns on the power supply system of the motor 5 and controls the output end of the motor 5 to drive the threaded rod 6 to rotate clockwise. Since the blocking plate 4 is slidably installed in the slide groove 3 and is restricted by the slide groove 3, the threaded rod 6 drives the blocking plate 4 threadedly installed therewith to move in the slide groove 3 toward the motor 5 when rotating. When the blocking plate 4 completely enters the interior of the slide groove 3, the motor 5 stops working, so that the blocking plate 4 can block and seal the feed hopper 2 and the drying box 1, which is beneficial to avoid the internal temperature of the drying box 1 from overflowing, resulting in reduced drying efficiency, and at the same time, it is beneficial to avoid external debris from falling into the interior of the drying box 1 and affecting the drying work of the lithium carbonate.

[0044] Working principle: When in use, all the equipment used in this device is connected to the external power supply. The staff controls the drying box 1 to work, and its internal temperature rises to dry the lithium carbonate material inside. The high-pressure and high-temperature gas generated during the drying work is placed in the heat insulation cover 7 through the pressure relief valve 10 to prevent the temperature from emitting to the external working environment. The multiple heat dissipation fins 901 in the heat insulation cover 7 absorb the gas temperature and conduct it to the part of the heat dissipation fins 901 and the heat dissipation plate 9 outside the external heat insulation cover 7. After the gas in the heat insulation cover 7 is cooled, it condenses into liquid and flows into the drainage block 702 from the rectangular through hole 701 at the bottom of the heat insulation cover 7 under the action of gravity. The liquid in the drainage block 702 flows into the To the water tank 8, it is mixed with the original liquid in the water tank 8. The staff turns on the power supply system of the water pump 801 and the booster pump 802, and controls the two to start working. The input end of the water pump 801 is at the bottom of the water tank 8. When the water pump 801 is working, its internal motor drives the impeller to rotate, thereby causing a pressure difference in the liquid in the water tank 8, which is convenient for sending the liquid into the booster pump 802 through the impeller. After the booster pump 802 works, the liquid is increased and transported to the delivery pipe 803. The delivery pipe 803 transports the pressurized liquid to the two secondary water storage blocks 804. After the internal liquid of the secondary water storage block 804 and the delivery pipe 803 is filled, the water pressure reaches the pressure value of the multiple spray nozzles 805, and the multiple spray nozzles 805 spray the liquid The body is atomized and sprayed onto the outer surfaces of the heat dissipation fins 901 and the heat dissipation plate 9, which is beneficial to evaporation and cooling of the heat dissipation fins 901 and the heat dissipation plate 9, thereby quickly taking away the temperature of the two on the outer body of the heat insulation cover 7, and then the heat dissipation fins 901 body located inside the heat insulation cover 7 continue to absorb the temperature of the gas inside the heat insulation cover 7, so that the gas condenses into liquid, further improving the cooling efficiency of the high-temperature and high-pressure gas at the pressure relief valve 10, which is beneficial to avoid a large amount of waste heat from being dissipated into the air. The high-temperature and high-pressure gas condenses into liquid and enters the water tank 8 for reuse, which is beneficial to saving water resources. When in use, after the material in the feed hopper 2 enters the interior of the drying box 1, the staff turns on the power supply system of the motor 5, controls the output end of the motor 5 to drive the thread The rod 6 rotates clockwise. Since the baffle plate 4 is slidably installed in the slide groove 3 and is restricted by the slide groove 3, the threaded rod 6 drives the baffle plate 4 threadedly installed therewith to move in the slide groove 3 toward the motor 5. When the baffle plate 4 completely enters the interior of the slide groove 3, the motor 5 stops working, so that the baffle plate 4 can block and seal the feed hopper 2 and the drying box 1, which is beneficial to avoid the internal temperature of the drying box 1 from overflowing, resulting in reduced drying efficiency. At the same time, it is beneficial to avoid external debris from falling into the drying box 1 and affecting the drying work of lithium carbonate. The model of the motor 5 is K2x-30x, the model of the water pump 801 is F42-203-055-5011, and the model of the booster pump 802 is 40-125.
