Description

Technical Field

[0001] The invention belongs to the technical field of lithium carbonate conveying devices, and in particular relates to a lithium carbonate production and processing conveying device. Background Art

[0002] Lithium carbonate is an inorganic compound and one of the main raw materials used in the production of new energy vehicle batteries. During the production and processing of lithium carbonate, a conveying device is needed to transport the lithium carbonate.

[0003] In production, the sulfuric acid production process is more mature and widely used in industry. The basic principle of this process is that sulfuric acid reacts with spodumene or lithium mica at a specific temperature to produce lithium sulfate. Subsequently, lithium sulfate is converted into lithium carbonate through a series of physical and chemical reactions, but the lithium carbonate product produced is usually a crude product and contains a certain amount of impurities. In order to meet the demand for high-purity lithium carbonate in the fields of lithium-ion batteries, medicine, etc., it is usually necessary to purify the crude product. The purification process is to dissolve lithium carbonate in water or other solvents, remove impurities through precipitation, filtration, crystallization and other steps to improve the purity. The crude product lithium carbonate easily absorbs moisture in the air, causing the lithium carbonate to absorb moisture and agglomerate. The agglomerated crude product lithium carbonate dissolves slowly in water or other solvents during the purification process, reducing the efficiency of production purification.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] like Figures 1 to 5 As shown, an embodiment of the present invention provides a lithium carbonate production, processing and conveying device, including a processing bin 1, a dehumidification structure is provided on the outside of the processing bin 1, and the dehumidification structure is used to dehumidify the air in the inner cavity of the processing bin 1, and a cold wind cooling structure is also provided on the outside of the processing bin 1 to prevent the material in the inner cavity of the processing bin 1 from overheating, and the inner cavity of the processing bin 1 is also provided with a scattering and dredging structure for scattering the material;

[0028] Wherein, the dehumidification structure includes a dehumidification bin 4, which is fixedly connected to the outside of the processing bin 1, and the inner cavity of the dehumidification bin 4 is fixedly connected with a dehumidification box 5, and the top of the dehumidification box 5 is fixedly connected with a discharge barrel 6, and the top of the discharge barrel 6 is fixedly connected with a storage bin 7, and the top of the storage bin 7 is threadedly connected with a plugging head 19, and the inner cavity of the discharge barrel 6 is movably sleeved with a conveying plate 8, and the side of the conveying plate 8 close to the outside of the dehumidification bin 4 is fixedly connected with a raised head 9, and the top of the dehumidification box 5 is fixedly connected with a support spring 10, and the middle part of the support spring 10 is fixedly connected with a descending rod 11, and the bottom end of the descending rod 11 is fixedly connected with a combing rod 12;

[0029] The top of the processing chamber 1 is fixedly connected to a servo motor 13, and the outer side of the processing chamber 1 is movably sleeved with a rotating disk 14, and the rotating disk 14 is rotatably connected to the output shaft of the servo motor 13 through a belt, and the bottom end of the rotating disk 14 is fixedly connected to a support rod 15, and the bottom end of the support rod 15 is provided with a reducer 16, and the support rod 15 is transmission-connected to the conveying plate 8 through the reducer 16;

[0030] The dehumidification box 5 is connected to the inner cavity of the discharge barrel 6, and the bottom end of the dehumidification bin 4 is fixedly connected to a water collecting bin 31, and the water collecting bin 31 is used to collect the product after the moisture-proof particles react. The dehumidification box 5 is located above the water collecting bin 31, and the bottom end of the water collecting bin 31 is fixedly connected to a drain pipe 18;

[0031] A screen 30 is fixedly connected to the connection between the processing chamber 1 and the moisture removal chamber 4 , and the moisture removal chamber 4 is connected to the inner cavity of the processing chamber 1 through the screen 30 .

[0032] In the embodiment, the plug 19 is first unscrewed, and then the moisture-proof particles are poured into the inner cavity of the storage bin 7. In this embodiment, the moisture-proof particles are calcium chloride particles. Then the servo motor 13 is started to drive the rotating disk 14 to rotate, and the reducer 16 is driven to operate through the rotating disk 14, and then the reducer 16 is used to reduce the speed and drive the conveying plate 8 to slowly flip in the inner cavity of the discharge barrel 6, so that the moisture-proof particles in the inner cavity of the storage bin 7 can pass through the discharge barrel 6 and fall into the inner cavity of the dehumidification box 5. When the moisture-proof particles in the inner cavity of the dehumidification box 5 are full, although the conveying plate 8 continues to rotate, the conveying plate 8 will have a downward squeezing force on the moisture-proof particles when it rotates into the moisture-proof particles in the dehumidification box 5. Because the moisture-proof particles are always in consumption, the extrusion force generated can make the moisture-proof particles closer together, thereby improving the effect of absorbing air moisture.

[0033] It should be noted that when the conveying plate 8 rotates, the protruding head 9 is driven to rotate, and the protruding head 9 presses the descending rod 11. At this time, the elasticity of the supporting spring 10 causes the descending rod 11 to shrink when being pressed. When the protruding part of the protruding head 9 is separated from the descending rod 11, the tension of the supporting spring 10 drives the combing rod 12 to move up and down in the inner cavity of the dehumidification box 5, thereby driving the moisture-proof particles to move, so that the original contacting side of the moisture-proof particles is exposed, further improving its ability to absorb moisture. At the same time, the up and down movement of the combing rod 12 in the inner cavity of the dehumidification box 5 also prevents the moisture-proof particles from agglomerating, and also improves its ability to absorb moisture. The moisture-proof particles in the inner cavity of the dehumidification box 5 absorb the moisture in the processing chamber 1 and the air entering the processing chamber 1, and the reaction product flows out through the dehumidification box 5 and is then discharged through the drain pipe 18 at the bottom of the water collection chamber 31.

[0034] It should also be noted that the combing rod 12 moves up and down in the inner cavity of the dehumidification box 5, driving the moisture-proof particles to move and breaking up the moisture-proof particles, which will make the moisture-proof particles loose, allowing air to pass through easily, causing moisture to pass through easily, and when the conveying plate 8 rotates to enter the moisture-proof particles in the dehumidification box 5, it will have a downward squeezing force on the moisture-proof particles, which can make the moisture-proof particles become compact, and the two have a mutually reinforcing effect.

[0035] like Figure 2As shown, an embodiment of the present invention provides a lithium carbonate production, processing and conveying device, wherein the cold air cooling structure comprises a support plate 20, wherein the support plate 20 is fixedly connected to a side of the dehumidification bin 4 away from the processing bin 1, and a cold air blower 21 is fixedly connected to the top of the support plate 20, and an air outlet pipe 22 is fixedly connected to the right side of the cold air blower 21, and an air blowing pipe 23 is fixedly connected to the right side of the air outlet pipe 22;

[0036] The air blowing pipe 23 is located in the inner cavity of the dehumidification chamber 4 and at a side of the dehumidification box 5 away from the screen 30 . Four air nozzles are fixedly installed on a side of the air blowing pipe 23 close to the dehumidification box 5 .

[0037] In the embodiment, cold air is generated by the air cooler 21 and transported to the inner cavity of the blowing pipe 23 through the outlet pipe 22, and then blown in the direction of the dehumidification box 5 through the four air nozzles of the blowing pipe 23. The cold air passes through the dehumidification box 5 for dehumidification and then enters the inner cavity of the processing bin 1, thereby cooling the material in the crushing process in the inner cavity of the processing bin 1. This is because when crushing the agglomerated lithium carbonate, the breaking rod 24 will rub against the lithium carbonate, and the lithium carbonate itself will also collide and rub against each other, causing the lithium carbonate to be heated. The cold air can reduce the temperature of the working environment and avoid overheating and decomposition of lithium carbonate with low thermal stability.

[0038] like Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a lithium carbonate production and processing conveying device, the breaking and dredging structure includes a breaking rod 24, the breaking rod 24 is fixedly sleeved on the output shaft of the servo motor 13, the bottom end of the breaking rod 24 is fixedly connected with a scraping rod 25, the bottom end of the scraping rod 25 is fixedly connected with a fixed wheel 26, the bottom end of the processing bin 1 is fixedly connected with a spring assembly 27, the top end of the spring assembly 27 is fixedly connected with a discharge screen plate 28, the outer side of the discharge screen plate 28 is fixedly connected with a groove ring 29, and the fixed wheel 26 is fitted to the top end of the groove ring 29;

[0039] The spring assembly 27 is composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring cavity;

[0040] The bottom end of the processing chamber 1 is fixedly connected to the entry chamber 2, the bottom end of the entry chamber 2 is fixedly connected to the auger conveying device 3, and the top end of the processing chamber 1 is fixedly installed with a feeding pipe 17;

[0041] In the embodiment, after the material enters the inner cavity of the processing bin 1 from the feeding pipe 17 at the top of the processing bin 1, the servo motor 13 is started to drive the breaking rod 24 to rotate, so that the material is preliminarily broken up by the breaking rod 24;

[0042] When the breaking rod 24 rotates, it drives the scraping rod 25 to scrape the materials that may be contaminated on the inner wall of the processing bin 1, and then the fixed wheel 26 at the bottom end of the scraping rod 25 moves at the top end of the groove ring 29. When the fixed wheel 26 is not located in the groove of the groove ring 29, the groove ring 29 is pressed downward, so that the spring assembly 27 contracts. When the fixed wheel 26 moves to the groove at the top of the groove ring 29, the spring assembly 27 loses its limit and drives the groove ring 29 to bounce upward, driving the discharge screen plate 28 to vibrate. Through the vibration of the discharge screen plate 28, the broken materials are separated, and the unbroken logistics continue to remain on the discharge screen plate 28 for breaking. The agglomerated lithium carbonate is more easily soluble in water after being broken, thereby improving the efficiency of subsequent purification and improving the efficiency of production. The processed materials enter the inner cavity of the auger conveying equipment 3 through the entry bin 2 for transportation.

[0043] Working principle and use process: first pull out the plug 19, then pour the moisture-proof particles into the inner cavity of the storage bin 7, input the material into the inner cavity of the processing bin 1 from the feeding pipe 17 of the processing bin 1, then start the servo motor 13 to drive the scattering rod 24 to rotate to scatter the material, and use the scraping rod 25 to scrape the material on the inner wall of the processing bin 1. When the scraping rod 25 moves, the fixed wheel 26 fits the top of the groove ring 29, and the elasticity of the spring assembly 27 makes the groove ring 29 shake after being pressed by the fixed wheel 26, thereby driving the discharge screen plate 28 to shake, separating the scattered materials, and leaving the unbroken logistics on the discharge screen plate 28 for crushing;

[0044] At the same time, the air cooler 21 is started to generate cold air, which is transported to the air blowing pipe 23 along the air outlet pipe 22, blown out to the dehumidification box 5 through the air blowing pipe 23, and passes through the dehumidification box 5, so that the moisture-proof particles in the inner cavity of the dehumidification box 5 dry the air entering the inner cavity of the processing bin 1, and the cold air cools the material after entering the processing bin 1;

[0045] When the breaking rod 24 rotates, it drives the rotating disk 14 to rotate, and the supporting rod 15 is driven to rotate through the rotating disk 14. At this time, the conveying plate 8 is driven to decelerate the rotation through the reducer 16, so that the moisture-proof particles in the inner cavity of the storage bin 7 are conveyed to the inner cavity of the dehumidification box 5 by the conveying plate 8, and the moisture-proof particles in the inner cavity of the dehumidification box 5 are squeezed to make them tighter. The conveying plate 8 drives the raised head 9 to rotate, and the raised head 9 presses the descending rod 11. At this time, through the elasticity of the supporting spring 10, the protruding part of the raised head 9 is separated from the descending rod 11, and the elasticity of the supporting spring 10 can drive the combing rod 12 to move. Through the activity of the combing rod 12, the moisture-proof particles in the inner cavity of the dehumidification box 5 are moved, thereby driving the moisture-proof particles to move, so that the original contact side between the moisture-proof particles is exposed, further improving its ability to absorb moisture. At the same time, the combing rod 12 moves up and down in the inner cavity of the dehumidification box 5 to prevent the moisture-proof particles from agglomerating, and also improves its ability to absorb moisture.
