The main purpose of the drying process is to remove moisture on its surface to improve the purity of lithium carbonate and prepare for its subsequent sintering process.

[0041] Embodiment 1:

[0042] See also Figure 1-11The present invention provides a lithium carbonate drying device, comprising a drying box 1, wherein the outer end surface of the drying box 1 is rotatably connected to a box door plate 2, and further comprising a track frame 3, wherein the track frame 3 is fixed to the inner wall of the end surface of the drying box 1 away from the box door plate 2, wherein the inner wall of the track frame 3 is slidably connected to a moving frame 4, and the inner wall of the moving frame 4 is rotatably connected to a drying cylinder 5;

[0043] Track plates 6, two track plates 6 are provided and fixed in parallel to the bottom inner wall of the drying box 1, a material receiving frame 7 is provided below the drying cylinder 5 and is slidably mounted on the inner walls of the two track plates 6, a wind blade 8 is rotatably mounted on the bottom inner wall of the drying box 1 is provided on one side of the material receiving frame 7, a driving motor 9 coaxially connected to the wind blade 8 is provided below the drying box 1, a traveling material turning mechanism 10 matched with the moving frame 4 is provided below the drying box 1, and a swing balancing mechanism 11 matched with the drying cylinder 5 is provided on the top surface of the moving frame 4;

[0044] It should be noted that an air inlet pipe is connected to the outer wall of the drying box 1 away from the door panel 2, and an exhaust pipe is connected to the top thereof. An electrical component for heating the internal space is also provided inside the drying box 1 to ensure the smooth drying of lithium carbonate in the drying cylinder 5.

[0045] It should be noted that the wind blades 8 are driven by the driving motor 9 to rotate synchronously, so that the hot air in the drying box 1 is in a flowing state, so as to facilitate better dehydration and drying of the lithium carbonate in the drying cylinder 5;

[0046] By setting the traveling material turning mechanism 10, it moves synchronously with the drive of the driving motor 9, so that the moving frame 4 performs reciprocating translational motion on the track frame 3, that is, drives the drying cylinder 5 to reciprocate in the drying box 1. At the same time, the traveling material turning mechanism 10 continuously turns the lithium carbonate raw material inside the drying cylinder 5 in a reciprocating state, thereby avoiding the accumulation of lithium carbonate in the drying box 1 and significantly improving the adequacy of the drying process of lithium carbonate in the drying cylinder 5.

[0047] The swing balancing mechanism 11 is set up, during the reciprocating translational motion of the mobile frame 4 and the drying cylinder 5, the drying cylinder 5 moves along with the translational action of the mobile frame 4 in the drying box 1, and the drying cylinder 5 performs a reciprocating swing process in the mobile frame 4, thereby further improving the turning effect of lithium carbonate, and effectively preventing lithium carbonate from adhering to the inner wall of the drying cylinder 5, effectively reducing the workload of subsequent cleaning and maintenance of the drying cylinder 5;

[0048] Lithium carbonate to be dried is placed in the material receiving frame 7 and the drying cylinder 5. When drying the lithium carbonate, first a portion of lithium carbonate is placed in the material receiving frame 7 for preliminary preheating and drying in a stacking manner. After the preheating and drying is completed, the pre-dried lithium carbonate in the material receiving frame 7 is transferred to the drying cylinder 5, and a new portion of lithium carbonate is placed in the material receiving frame 7, thereby achieving simultaneous preheating and drying of the lithium carbonate in the material receiving frame 7 and mobile turning and drying of the preliminary dried lithium carbonate in the drying cylinder 5. The above operation is repeated multiple times, thereby continuously performing stacking preheating and drying as well as mobile turning and drying of multiple portions of lithium carbonate, effectively improving the drying effect and efficiency of the lithium carbonate.

[0049] Further Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 and Fig.11 As shown, it is worth to explain in detail that the traveling material turning mechanism 10 includes a moving rod 101, two moving rods 101 are provided and are distributed in parallel and penetrate the side wall of the drying box 1, the top ends of the two moving rods 101 are fixed to the surface of the moving frame 4, the bottom ends of the two moving rods 101 are commonly fixed with a moving ring 102, and the outer sides of the top ends of the two moving rods 101 are provided with a turning piece 103 that cooperates with the drying cylinder 5;

[0050] The mounting plate 104 is fixed to the bottom surface of the drying box 1. The top surface of the mounting plate 104 is provided with a driving gear 105 coaxially fixed with the output end of the driving motor 9. The top surface of the mounting plate 104 is rotatably connected with a driven gear 106. The driving gear 105 is meshedly connected with the driven gear 106. A rotating column 107 is fixed to the top surface of the driven gear 106. The moving ring 102 is sleeved on the periphery of the rotating column 107.

[0051] It should be noted that the driving gear 105 rotates synchronously with the drive of the driving motor 9, and the meshing transmission effect of the driving gear 105 and the driven gear 106 makes the driven gear 106 and the rotating column 107 rotate synchronously in a circular motion. When the rotating column 107 rotates in a circular motion with the driven gear 106, the rotating column 107 is always located in the moving ring 102 and is squeezed with the moving ring 102. At the same time, the moving ring 102 is guided and limited by the moving rod 101, so that the moving ring 102 is synchronously reciprocated with the continuous circular rotation of the rotating column 107. The moving rod 101 is connected to the moving frame 4, so that the moving frame 4 is reciprocated in the track frame 3, that is, the drying cylinder 5 is reciprocated in the drying box 1, and the mobile drying of lithium carbonate in the drying cylinder 5 is achieved through the drying effect of the hot air in the drying box 1.

[0052] The material turning member 103 is set so that when the drying cylinder 5 moves back and forth with the moving frame 4, the material turning member 103 performs continuous rotational material turning processing inside the drying cylinder 5, thereby effectively avoiding the accumulation of lithium carbonate in the drying cylinder 5 and greatly increasing the contact area between lithium carbonate and hot air, thereby effectively improving the drying effect of lithium carbonate;

[0053] It should be noted that if Fig.11 As shown, when the driving gear 105 rotates with the driving motor 9, the driven gear 106 and the rotating column 107 also rotate synchronously, and the moving ring 102 slides through the top of the moving rod 101 and penetrates the outer surface of one side of the drying box 1. At this time, the continuously rotating rotating column 107 applies an extrusion thrust in the rotating state to the moving ring 102, so that the moving ring 102 reciprocates as a whole on the bottom surface of the drying box 1 through the sliding guide of the moving rod 101. At this time, as the rotating column 107 rotates synchronously and continuously with the driven gear 016, the position of the rotating column 107 at the inner ring of the moving ring 102 changes periodically.

[0054] Further Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, it is worth specifically explaining that the material turning member 103 includes a fixed sleeve 1031, the fixed sleeve 1031 is fixed to the top surface of the mobile frame 4, the interior of the drying cylinder 5 is provided with a rotating rod 1032 rotatably connected to the inner wall of the fixed sleeve 1031, the inner wall of the drying cylinder 5 is provided with a plurality of material turning blades 1033 which are all tightly sleeved with the outer surface of the rotating rod 1032, and the outer end of the fixed sleeve 1031 is provided with a material turning gear 1034 which is tightly sleeved with the outer surface of the rotating rod 1032;

[0055] A fixed rack rod 1035, the fixed rack rod 1035 is fixed to the inner wall of the end surface of the drying box 1, and the material turning gear 1034 and the fixed rack rod 1035 are meshingly connected;

[0056] It should be noted that when the movable frame 4 reciprocates on the track frame 3, the end of the rotating rod 1032 rotates on the fixed rack rod 1035 through the material turning gear 1034, so that the material turning blade 1033 continuously rotates on the fixed sleeve 1031 along with the rotating rod 1032. Since the fixed sleeve 1031 and the drying cylinder 5 both move back and forth synchronously with the movable frame 4, the material turning blade 1033 can continuously turn the material in the drying cylinder 5, thereby effectively avoiding the accumulation of lithium carbonate and greatly improving the adequacy of the drying process of lithium carbonate in the drying cylinder 5.

[0057] Further Figure 4 , Figure 5 and Figure 6 As shown, it is worth to explain in detail that the ends of the plurality of material turning blades 1033 are all arranged in an arc surface, and the air holes 12 opened on the outer surface of the top of the drying cylinder 5 are arranged above the plurality of material turning blades 1033;

[0058] It should be noted that the arc surface of the end of the material turning blade 1033 is arranged to fit the inner wall of the drying cylinder 5, so that when the material turning blade 1033 performs continuous material turning processing in the drying cylinder 5, it can also effectively prevent lithium carbonate from adhering to the inner wall of the drying cylinder 5;

[0059] Two adjacent turning blades 1033 are in contact with each other and are staggered at equal angles. Two turning blades 1033 are installed on the rotating rod 1032 in the same manner, so that the lithium carbonate is turned in all directions in the drying cylinder 5, which improves the turning effect of the lithium carbonate to a certain extent.

[0060] The provision of the air holes 12 allows the hot air in the drying box 1 to better enter the drying cylinder 5, and cooperates with the continuous turning of lithium carbonate in the drying cylinder 5, thereby further improving the contact between the lithium carbonate and the hot air. The air holes 12 are not provided on the bottom outer surface of the drying cylinder 5, which can effectively prevent the drying cylinder 5 from falling when it reciprocates with the movable frame 4.

[0061] Further Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that a discharge channel 13 opened on the outer surface of the bottom of the drying cylinder 5 is provided below the air vent 12, and a discharge frame 14 connected to the bottom surface of the drying cylinder 5 is provided below the discharge channel 13, and an arc-shaped sealing plate 15 is slidably connected inside the discharge channel 13, and a sealing plug 16 is detachably connected to the outer end surface of the drying cylinder 5 close to the box door plate 2;

[0062] It should be noted that the lithium carbonate that has been preheated and dried in the receiving frame 7 is fed from the sealing plug 16 by opening the sealing plug 16 and using the external funnel-shaped inclined feeding pipe, so that the lithium carbonate can be better fed from the sealing plug 16;

[0063] The arc-shaped sealing plate 15 is provided with a groove at its outer end, so that the arc-shaped sealing plate 15 can be easily pulled out from the bottom of the drying cylinder 5. After the lithium carbonate is dried, the receiving frame 7 at the bottom can be pulled out and replaced with another receiving frame 7. By sliding and pulling out the arc-shaped sealing plate 15, the lithium carbonate in the drying cylinder 5 can pass through the unloading channel 13 to the discharging frame 14, and then fall into the receiving frame 7 for collection and processing;

[0064] It should be noted that the driving motor 9 can be a stepper motor, and the opening size of the material receiving frame 7 is larger than the material opening size of the material discharging frame 14. The driving motor 9 can be driven to make the rotating column 107 rotate slightly with the driven gear 106, so that the drying cylinder 5 and the material discharging frame 14 can perform a small displacement movement with the moving frame 4. At the same time, the material turning blade 1033 turns the material slightly in the drying cylinder 5, thereby improving the convenience of unloading and transferring lithium carbonate to the material receiving frame 7 to a certain extent.

[0065] Further Figure 3 , Figure 4 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the swing balancing mechanism 11 includes a docking sleeve 111, which is sleeved on the outer surface of the rotating rod 1032 and fixed at the center of the outer end surface of the drying cylinder 5, and the outer surface of the docking sleeve 111 is tightly sleeved with a swing gear 112, and the outer periphery of the swing gear 112 is meshedly connected with a U-shaped rack rod 113;

[0066] An L-shaped plate 114 is fixed to the top surface of the mobile frame 4. A balancing rod 115 is slidably penetrated through the top surface of the L-shaped plate 114. The bottom end of the balancing rod 115 is fixed to the top surface of the U-shaped rack rod 113. A balancing spring 116 is arranged on the periphery of the balancing rod 115 and is fixed to the opposite surfaces of the U-shaped rack rod 113 and the L-shaped plate 114. A running wheel 117 is installed on the top of the balancing rod 115. A corrugated rod 118 is fixed to the inner side wall of the drying box 1. The bottom surface of the corrugated rod 118 is in contact with the wheel body of the running wheel 117.

[0067] It should be noted that when the movable frame 4 performs reciprocating translational motion on the track frame 3, the walking wheel 117 is driven to perform contact walking on the surface of the corrugated rod 118. At this time, the balance rod 115 is acted upon by the elastic force of the balance spring 116, so that the balance rod 115 performs up and down reciprocating motion on the L-shaped plate 114, so that the U-shaped rack rod 113 synchronously performs up and down reciprocating motion on the movable frame 4, and through the meshing transmission action of the U-shaped rack rod 113 and the swing gear 112, the swing gear 112 and the docking sleeve 111 perform continuous reciprocating swing, that is, the drying cylinder 5 is reciprocatingly swung on the movable frame 4, thereby further preventing the accumulation and adhesion of lithium carbonate during the drying process.

[0068] The present embodiment has the following working process: when drying and drying multiple portions of lithium carbonate, firstly, a portion of lithium carbonate is placed in the material receiving frame 7 for preheating and drying, and then the sealing plug 16 is opened to transfer it to the drying cylinder 5 and a new portion of lithium carbonate is placed in the material receiving frame 7, thereby achieving preheating and drying of the lithium carbonate in the material receiving frame 7 and re-drying of the lithium carbonate in the drying cylinder 5, and repeating the above operation to dry multiple portions of lithium carbonate. This method of drying and drying lithium carbonate improves the adequacy of drying and drying lithium carbonate to a certain extent;

[0069] The wind blades 8 are driven by the driving motor 9 to rotate in the drying box 1, so that the hot air fills the entire chamber of the drying box 1, and through the mutual cooperation of the traveling turning mechanism 10 and the swing balancing mechanism 11, the movable frame 4 and the drying cylinder 5 are made to perform reciprocating translational motion in the drying box 1, and the drying cylinder 5 is reciprocatingly swung on the moving movable frame 4, so that the lithium carbonate is mobile dried in the drying cylinder 5. Through the setting of the turning member 103 in the traveling turning mechanism 10, the turning blades 1033 are continuously turned over by the moving frame 4 in the drying cylinder 5 to process the lithium carbonate, and through the top ventilation effect of the air vents 12, the hot air is more fully in contact with the lithium carbonate, so that the drying effect and drying rate of the lithium carbonate are effectively improved.

[0070] Embodiment 2:

[0071] Based on the first embodiment, Figure 3 , Figure 4 and Figure 7 As shown, it is worth to explain in detail that the periphery of the wind blade 8 is provided with a protective cover shell 17 fixed to the inner wall of the drying box 1, and a partition plate 18 fixed to the inner wall of the drying box 1 is provided above the protective cover shell 17, and a piston plate 19 is slidably connected between the partition plate 18 and the inner wall of the drying box 1, and three supporting springs 20 equidistantly distributed are fixed between the piston plate 19 and the opposite surface of the drying box 1, and a resisting rod 21 matched with the piston plate 19 is fixed to the bottom surface of the moving frame 4;

[0072] It should be noted that when the resistance rod 21 moves with the movable frame 4 to contact with the piston plate 19, the piston plate 19 is driven to compress the support spring 20, which can not only achieve buffering when the movable frame 4 moves into the drying box 1 to prevent the movable frame 4 from reciprocating too quickly, but also enable the piston plate 19 to form an exhaust process at the partition plate 18, thereby improving the fluidity of the hot air in the drying box 1 and improving the drying effect of the lithium carbonate to a certain extent.

[0073] Further Figure 1As shown, it is worth explaining in detail that a transparent window 22 is provided on the outer end surface of the drying box 1 close to the box door panel 2, and the transparent window 22 is adapted to the height of the drying cylinder 5. The setting of the transparent window 22 facilitates intuitive observation of the smoothness of the reciprocating movement of the drying cylinder 5 in the drying box 1.

[0074] In summary, in combination with the two embodiments, it can be known that: through the driving of the driving motor 9 and the mutual cooperation of the traveling turning mechanism 10 and the swing balancing mechanism 11, the movable frame 4 and the drying cylinder 5 are made to perform reciprocating translational motion in the drying box 1, and at the same time, the drying cylinder 5 is made to reciprocate on the moving movable frame 4. Through the setting of the turning piece 103 in the traveling turning mechanism 10, the turning blade 1033 is made to continuously turn the lithium carbonate in the drying cylinder 5 as the movable frame 4 moves, so that the reciprocating movement of the movable frame 4, the reciprocating swing of the drying cylinder 5 and the continuous turning rotation of the turning blade 1033 are synchronously performed, and through the top ventilation effect of the air vent 12, the hot air is made to be in more sufficient contact with the lithium carbonate, thereby effectively improving the drying effect and drying rate of the lithium carbonate.

[0075] Through the mutual cooperation of the movable frame 4, the abutment rod 21, the piston plate 19 and the support spring 20, it is possible to achieve buffering when the movable frame 4 moves into the drying box 1 to prevent the movable frame 4 from reciprocating too quickly, and the piston plate 19 can also form an exhaust process at the partition plate 18, thereby improving the hot air flowability in the drying box 1 and improving the drying effect of the lithium carbonate to a certain extent.

[0076] The driving motor 9 can be purchased from the market and equipped with a separate power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
