Description

Technical Field

[0001] The invention relates to the technical field of drying devices, and in particular to a drying device for lithium carbonate. Background Art

[0002] The chemical formula of lithium carbonate is Li2CO3, the molecular weight is 73.89, it is a colorless monoclinic crystal, the melting point is 720°C, it is soluble in water and dilute acid, insoluble in ethanol and acetone, the thermal stability is lower than the carbonates of other elements in the same group in the periodic table, it is not deliquescent in the air, and can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solution. Its aqueous solution can be converted into an acid salt by passing carbon dioxide, which releases carbon dioxide when heated to form lithium carbonate. The aqueous solution is hydrolyzed when boiled, and is used as a raw material for ceramics, glass, ferrite, etc., and for spraying silver paste on components, etc.

[0003] However, the prior art still has the following disadvantages in the process of drying lithium carbonate:

[0004] Generally, when drying, lithium carbonate needs to be put into the drying equipment at one time for drying. Because too much lithium carbonate is put into the drying equipment at one time, the drying is not uniform and the drying process takes a long time.

[0005] For example, the utility model with announcement number CN217131722U directly places lithium carbonate on a tray for drying. Since the lithium carbonate is wet before, it is easy to solidify together, which affects the subsequent drying.

[0006] After drying, the temperature of lithium carbonate is relatively high, making it inconvenient for workers to transport and store it.

[0007] In view of the above problems, the present invention document proposes a drying device for lithium carbonate. Summary of the invention

[0008] The invention provides a drying device for lithium carbonate, which solves the shortcomings of the prior art that too much lithium carbonate is added at one time, resulting in uneven drying, easy solidification, and high temperature, which is convenient for workers to transport and store.

[0009] The present invention provides the following technical solutions:

When the rotating shaft drives the upper hollow drying plate and the lower hollow drying plate to rotate to evenly dry the raw materials, when the discharge holes cooperate with the through holes, the raw materials in the upper hollow drying plate and the lower hollow drying plate can just fall downwards and fall into the first guide plate and the second guide plate respectively, which are used for drying the raw materials again and storing the raw materials.

The crushing plate 29 can squeeze the raw material on the upper hollow drying plate 2 and crush the solidified raw material, so as to facilitate the uniform drying of the raw material in the later stage.

[0061] Reference Figure 1 Two retaining rings 4 are fixedly connected in the upper hollow drying plate 2, and the tops of the two retaining rings 4 are rotatably connected with the bottoms of the upper hollow drying plate 2 and the lower hollow drying plate 3 respectively. The bottoms of the upper hollow drying plate 2 and the lower hollow drying plate 3 are both provided with discharge holes 5, and the two retaining rings 4 are both provided with through holes 6, and the discharge holes 5 and the through holes 6 cooperate with each other. When the rotating shaft 14 drives the upper hollow drying plate 2 and the lower hollow drying plate 3 to rotate to evenly dry the raw materials, when the discharge holes 5 cooperate with the through holes 6, the raw materials in the upper hollow drying plate 2 and the lower hollow drying plate 3 can just fall downward, and fall into the first guide plate 21 and the second guide plate 25 respectively, for drying the raw materials again and storing the raw materials.

[0062] Reference Figure 1 An exhaust hole 16 is provided at the top of the drying box 1, and a fan 17 is provided in the exhaust hole 16. The bottom end of the rotating shaft 14 of the fan 17 is fixedly connected to a first fixing rod 15, and the bottom end of the first fixing rod 15 is fixedly connected to the top of the rotating shaft 14. A plurality of resistance wire heating plates 13 are fixedly connected to the inner wall of the drying box 1, and the resistance wire heating plates 13 are located below the lower hollow drying plate 3. When the blower 11 blows the hot air in the drying box 1 upward to dry the raw materials, the hot air can drive the fan 17 to rotate, and the fan 17 drives the rotating shaft 14 to rotate, which facilitates the uniform drying of the raw materials in the later stage.

[0063] Reference Figure 4A material distribution plate 22 is fixedly sleeved on the outer wall of the rotating shaft 14, and the material distribution plate 22 is located between the upper hollow drying plate 2 and the lower hollow drying plate 3. A first material guide plate 21 located below the through hole 6 is fixedly connected to the inner wall of one side of the drying box 1, and the bottom end of the first material guide plate 21 is located above the material distribution plate 22, and a circular ring 23 is fixedly connected to the top of the material distribution plate 22. A plurality of material distribution grooves 24 are provided on the top of the material distribution plate 22. After the raw materials in the upper hollow drying plate 2 are initially dried, they fall onto the rotating material distribution plate 22 through the first material guide plate 21. The rotation of the material distribution plate 22 can prevent the raw materials from accumulating on one side of the top of the material distribution plate 22, and the material distribution plate 22 can make the raw materials slide off the material distribution grooves 24 when rotating, so that the raw materials can be evenly sprinkled on the lower hollow drying plate 3, thereby avoiding the accumulation of raw materials on the lower hollow drying plate 3.

[0064] Reference Figure 8 A rotating shaft 37 is rotatably connected in the hollow tube 9, and a plurality of wind gathering plates 38 are fixedly connected to the outer wall of the rotating shaft 37. A wind shield 42 located above the rotating shaft 37 is fixedly connected to the inner wall of one side of the hollow tube 9. A round rod 39 located above the placement tray 10 is fixedly connected in the storage box 7. A push plate 40 is rotatably sleeved on the outer wall of the round rod 39. A pushing rod 41 that touches the push plate 40 slides through the hollow tube 9. External air enters the hollow tube 9, and the external air pushes the rotating shaft 37 and the wind gathering plates 38 to rotate. The wind gathering plates 38 can push the push plates 40 to reciprocate when rotating in cooperation with the push rod 41, and the reciprocating rotation of the push plates 40 can level the raw materials entering from the second guide plate 25 to prevent the raw materials from piling up on one side and affecting the subsequent storage of raw materials.

[0065] Working principle: raw materials are gradually injected into the upper hollow drying plate 2 through the feed hole on one side of the drying box 1, and then the blower 11 is started. The blower 11 discharges the outside air into the hollow tube 9 through the air drying structure 8. The air entering the hollow tube 9 is dried by the air drying structure 8 and absorbs the moisture therein. The blower 11 injects the dry air into the drying box 1, and the resistance wire heating plate 13 heats the air entering the drying box 1. The hot air floats upward. When the hot air moves upward, it first dries the raw materials in the lower hollow drying plate 3. The dried air carries part of the moisture in the raw materials and moves to the upper hollow drying plate 2 to dry the raw materials on the upper hollow drying plate 2. Then the hot air moves upward to push The fan 17 rotates, and the fan 17 drives the rotating shaft 14, the upper hollow drying plate 2 and the lower hollow drying plate 3 to rotate slowly. When the upper hollow drying plate 2 and the lower hollow drying plate 3 rotate slowly, the turning plate 20 can stir-fry the raw materials in the upper hollow drying plate 2 and the lower hollow drying plate 3, so that the front and back of the raw materials can be dried, and the discharge holes 5 at the bottom of the upper hollow drying plate 2 and the lower hollow drying plate 3 are aligned with the corresponding through holes 6, and the stir-fried and dried raw materials fall on the first guide plate 21 and the second guide plate 25 respectively, and the raw materials on the first guide plate 21 fall on the distribution plate 22, and the rotating shaft 14 drives the distribution plate 22 to rotate, which can prevent the raw materials from accumulating on one side of the distribution plate 22, and the distribution plate 22 can rotate. The raw materials are made to slide down from the material distribution trough 24, and then the raw materials can be sprinkled on the lower hollow drying plate 3 respectively, so as to avoid the accumulation of raw materials on the lower hollow drying plate 3. The raw materials dropped from the upper hollow drying plate 2 to the lower hollow drying plate 3 can be further dried, so as to perform double drying of the raw materials. During the drying process, the raw materials can be gradually added to the upper hollow drying plate 2, which can not only increase the drying efficiency but also make the raw materials evenly dried. The raw materials on the second material guide plate 25 enter the storage box 7 for storage. Since the blower 11 injects the air of the storage box 7 into the drying box 1, the outside air enters the hollow tube 9, and the outside air drives the rotating shaft 37 and the air collecting plate 38 to rotate. The air collecting plate 38 rotates and pushes The movable rod 41 cooperates to push the push plate 40 to reciprocate, and the reciprocating rotation of the push plate 40 can level the raw materials entering from the second guide plate 25 to prevent the raw materials from piling up on one side and affecting the subsequent storage of the raw materials. The outside air entering the hollow tube 9 can reduce the temperature of the hollow tube 9, and the dried raw materials can be cooled through the hollow tube 9. In addition, when the raw materials enter the upper hollow drying plate 2, the rotating shaft 14 drives the upper hollow drying plate 2 and the arc plate 32 to rotate. The cooperation of the arc plate 32 and the L-shaped plate 31 can make the crushing plate 29 reciprocate up and down. The crushing plate 29 can squeeze the raw materials on the upper hollow drying plate 2 and crush the solidified raw materials, which is convenient for uniform drying of the raw materials in the later stage.
