Specific embodiments
[0024] The following further elaborates on the present utility model in conjunction with embodiments: Embodiment
[0025] As Figures 1-6 shown, the present utility model provides a lithium carbonate crystallization drying device, including a drying main body 1. Both ends at the top of the drying main body 1 are fixedly connected with slide rails 2. The inner wall of the slide rails 2 is slidably connected with a cover 3. The inner wall of the cover 3 is fixedly connected with an electric heating coil 4. The center at the top of the outer wall of the cover 3 is fixedly connected with a motor 5. The output end of the motor 5 is fixedly connected with a stirring rod 6. The left side of the outer wall of the drying main body 1 is fixedly connected with a drain pipe 7. One end of the drain pipe 7 is fixedly connected with a waste liquid bin 8. The top of the waste liquid bin 8 is sleeved with a guiding pipe 9. The top of the guiding pipe 9 is fixedly connected with a fixing table 10. The center at the top of the fixing table 10 is clamped with a filter barrel 11. The four sides at the bottom of the fixing table 10 are fixedly connected with vibrators 12.
[0026] In this embodiment, by arranging slide rails 2 at both ends of the top of the drying main body 1, pulling the pull rod arranged on the outer wall of the cover 3, the cover 3 is moved along the slide rails 2 to the top. At this time, the lithium carbonate raw material is introduced into the filter barrel 11 arranged on the top of the fixing table 10. Then, the pull rod is pulled to close the cover 3 and the fixing table 10. At this time, the motor 5 arranged at the center of the top of the outer wall of the cover 3 is started, so that the motor 5 drives the stirring rod 6 to stir the lithium carbonate raw material in the filter barrel 11. At the same time, the electric heating coil 4 arranged on the inner wall of the cover 3 is started to heat the lithium carbonate raw material. During this period, the sodium carbonate solution is continuously added into the filter barrel 11 until the lithium carbonate raw material is separated from the impurities. The waste liquid flows into the guiding pipe 9 along the filter barrel 11, and the waste liquid is discharged into the waste liquid bin 8 through the guiding pipe 9. Then, the waste liquid is discharged through the drain pipe 7. At this time, the hydrogen peroxide solution is injected into the filter barrel 11 to carry out a secondary reaction on the lithium carbonate. When the lithium carbonate crystallizes and precipitates, the above operation is repeated to discharge the waste liquid through the drain pipe 7. Then, the lithium carbonate crystals are continuously dried. At this time, the vibrators 12 arranged at the four sides of the bottom of the fixing table 10 are started to continuously vibrate the agglomerated and precipitated lithium carbonate crystals in the filter barrel 11 to separate the crystals from each other, solving the problem that in the traditional lithium carbonate crystal drying device during use, the lithium carbonate crystals are easy to agglomerate after reacting with the reagent, and when drying them, it is easy to cause uneven heating of the lithium carbonate crystals. Embodiment
[0027] As Figures 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, buffers 13 are fixedly connected to the four corners of the inner wall top of the drying main body 1, the output ends of the buffers 13 are fixedly connected to the four corners of the outer wall of the fixing table 10, a limiting groove 14 is opened at the top of the inner wall of the fixing table 10, a retaining piece 15 is clamped on the inner wall of the limiting groove 14, and the bottom of the retaining piece 15 is lapped with the outer wall of the filter barrel 11.
[0028] In this embodiment, by arranging buffers 13 at the four corners of the inner wall top of the drying main body 1, when the vibrators 12 vibrate the agglomerated and precipitated lithium carbonate crystals in the filter barrel 11, the buffers 13 are used to buffer the fixing table 10. By arranging a limiting groove 14 at the top of the inner wall of the fixing table 10, the retaining piece 15 is passed through the top of the filter barrel 11 and embedded into the limiting groove 14 to fix the filter barrel 11, avoiding the filter barrel 11 from toppling during the vibration of the vibrators 12, thereby causing damage to the internal parts. Embodiment
[0029] As Figures 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, one end of the outer wall top of the cover 3 far away from the motor 5 is fixedly connected with a telescopic pipe 16, one end of the telescopic pipe 16 is fixedly connected with a flow dividing valve 17, and the input end of the flow dividing valve 17 is fixedly connected with a plurality of liquid storage bins 18.
[0030] In this embodiment, distilled water, sodium carbonate solution and hydrogen peroxide solution are respectively injected into the liquid storage bin 18. When it is necessary to mix the lithium carbonate raw materials in the filter barrel 11, the flow dividing valve 17 provided at the output end of the liquid storage bin 18 is opened, and the corresponding solution is led along the telescopic tube 16 provided at the output end of the flow dividing valve 17 and discharged into the filter barrel 11 through the sealing cover 3, which is convenient for subsequent multiple and small-scale addition of the lithium carbonate raw materials. Embodiment
[0031] As Figures 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a vacuum tube 19 is fixedly connected to the top of the outer wall on the right side of the drying main body 1, one end of the vacuum tube 19 is fixedly connected to the outer wall of the guiding tube 9, and the bottom of the filter barrel 11 is composed of a PES membrane and a PVDF membrane, and a cavity is provided between the PES membrane and the PVDF membrane.
[0032] In this embodiment, by providing the vacuum tube 19 at the top of the outer wall on the right side of the drying main body 1, after the lithium carbonate reaction in the filter barrel 11 is completed, the air in the guiding tube 9 is pumped out along the vacuum tube 19 by using a vacuum pump, so that the air pressure in the guiding tube 9 becomes smaller, thereby pumping out the waste liquid in the filter barrel 11. Since the bottom of the filter barrel 11 is composed of a PES membrane and a PVDF membrane respectively, and a cavity is provided between the PES membrane and the PVDF membrane, the waste liquid passing through the PES membrane is secondarily precipitated in the cavity, and the precipitated waste liquid flows through the PVDF membrane under the influence of air pressure and flows into the waste liquid bin 8, solving the problem that in the traditional lithium carbonate crystallization reaction process, some lithium carbonate crystal particles are discharged along with the waste liquid before being completely reacted, resulting in waste.
[0033] Next, the working principle of the lithium carbonate crystallization drying device will be specifically described.
[0034] As Figures 1-6As shown, by injecting distilled water, sodium carbonate solution and hydrogen peroxide solution into the liquid storage bin 18 respectively, when the lithium carbonate raw material in the filter barrel 11 needs to be mixed, the diverter valve 17 set at the output end of the liquid storage bin 18 is opened, and the corresponding solution is discharged into the filter barrel 11 through the cover 3 along the telescopic tube 16 set at the output end of the diverter valve 17, so as to facilitate the subsequent multiple small additions of the lithium carbonate raw material. By setting slide rails 2 at both ends of the top of the drying body 1, the pull rod set on the outer wall of the cover 3 is pulled to move the cover 3 to the top along the slide rails 2. At this time, the lithium carbonate raw material is introduced into the filter barrel 11 set on the top of the fixed platform 10, and then the pull rod is pulled to close the cover 3 and the fixed platform 10. At this time, the motor 5 set at the top center of the outer wall of the cover 3 is started. , the motor 5 drives the stirring rod 6 to stir the lithium carbonate raw material in the filter barrel 11, and at the same time, the electric heating coil 4 arranged on the inner wall of the cover 3 is started to heat the lithium carbonate raw material. During this period, sodium carbonate solution is continuously added to the filter barrel 11 until the lithium carbonate raw material is separated from the impurities. A vacuum tube 19 is arranged on the top of the right side of the outer wall of the drying body 1. When the reaction of the lithium carbonate in the filter barrel 11 is completed, the air in the guide pipe 9 is extracted along the vacuum tube 19 by a vacuum pump, so that the air pressure in the guide pipe 9 becomes small, thereby extracting the waste liquid in the filter barrel 11. Since the bottom of the filter barrel 11 is composed of a PES membrane and a PVDF membrane respectively, and a cavity is arranged between the PES membrane and the PVDF membrane, the waste liquid passing through the PES membrane is discharged in the air. Secondary precipitation is carried out in the cavity, and the waste liquid after precipitation passes through the PVDF membrane under the influence of air pressure and flows into the waste liquid bin 8, which solves the problem that in the traditional lithium carbonate crystallization reaction process, some lithium carbonate crystal particles have not reacted completely and are discharged with the waste liquid, thereby causing waste. The waste liquid flows into the guide pipe 9 along the filter barrel 11, and the waste liquid is discharged into the waste liquid bin 8 through the guide pipe 9, and then the waste liquid is discharged through the drain pipe 7. At this time, the hydrogen peroxide solution is injected into the filter barrel 11 to carry out secondary reaction on the lithium carbonate. When the lithium carbonate crystals are precipitated, the above operation is repeated, and the waste liquid is discharged through the drain pipe 7. Then the lithium carbonate crystals are continuously dried. At this time, the vibrators 12 arranged on the four sides of the bottom of the fixed platform 10 are started to vibrate the lithium carbonate precipitated in the filter barrel 11. The crystals are continuously vibrated to separate the crystals from each other. Buffers 13 are arranged at the four corners of the top of the inner wall of the drying body 1. When the vibrator 12 vibrates the agglomerated and precipitated lithium carbonate crystals in the filter barrel 11, the buffer 13 is used to buffer the fixed platform 10. A limiting groove 14 is arranged on the top of the inner wall of the fixed platform 10, and a baffle 15 is passed through the top of the filter barrel 11 and embedded in the limiting groove 14 to fix the filter barrel 11. This prevents the filter barrel 11 from tipping over during the vibration of the vibrator 12, thereby damaging the internal parts. This solves the problem that in the use of the traditional lithium carbonate crystal drying device, the lithium carbonate crystals are prone to agglomeration after reacting with the reagent, and the lithium carbonate crystals are prone to uneven heating when they are dried.
[0035] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
