Description

Technical Field

[0001] This utility model relates to the field of lithium phosphate preparation technology, and more specifically, to a synthesis apparatus for preparing lithium phosphate. Background Technology

[0002] Lithium phosphate is an inorganic compound mainly used in the production of colored phosphors, special glasses, optical disc materials, etc., and can also be used as a catalyst. Solvent synthesis is one of the commonly used methods for lithium phosphate preparation. Solvent synthesis mainly utilizes the extraction effect of solvents to extract the lithium phosphate component from the raw materials, and then further processes it to obtain the lithium phosphate product. For example, the patent application number 202021787934.1 proposes a high-efficiency synthesis device for synthesizing lithium hexafluorophosphate, which includes: a main cavity for holding low-temperature anhydrous hydrofluoric acid; a cover for sealing the main cavity to prevent gas leakage; a gas supply cam uniformly embedded in the side wall of the main cavity, which is integrated with the main cavity and has multiple sets of one-way gas supply valves; a gas supply device including a gas supply chamber and multiple sets of gas supply pipes uniformly connected to one side of the gas supply chamber, wherein the gas supply chamber is connected to the gas supply cam and the one-way gas supply valves thereon; and a stirring device including a rotating shaft driven by a motor and an impeller mounted on the rotating shaft. This significantly increases the contact area between the gas and the solution, and makes the contact between the gas and the solution more uniform in position. This solves the problem that in existing ventilation methods, the gas tends to repeatedly come into contact with local solutions, reducing the chance of contact with other parts of the solution, resulting in insufficient reaction and reduced synthesis efficiency of lithium hexafluorophosphate.

[0003] In existing synthesis apparatuses, after the gas is delivered into the apparatus containing the solution, some gas remains in the cavity above the liquid surface. The reaction rate between this gas and the solution is slow, which increases production time and reduces efficiency. Therefore, we propose an improved synthesis apparatus for lithium phosphate preparation. Utility Model Content

[0004] The main purpose of this invention is to provide a synthesis apparatus for lithium phosphate preparation, which can effectively solve the problem that after the gas is delivered into the synthesis apparatus containing the solution, some gas remains in the cavity above the liquid surface.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A synthesis apparatus for preparing lithium phosphate includes a support frame and a barrel. The barrel is rotatably mounted on one side of the support frame. A driving mechanism is provided on the top of the support frame and the barrel. A gas delivery pipe is provided at the center of the upper surface of the barrel.

[0008] Preferably, a conveying cover is installed on the top inner wall of the barrel, and several through holes are opened through the lower outer surface of the conveying cover, with one end of the gas conveying pipe located inside the conveying cover.

[0009] Preferably, the drive mechanism includes a mounting frame and an annular mounting plate. The mounting frame is fixedly mounted on the top of the support frame, the annular mounting plate is mounted on the outer side of the upper surface of the barrel, and a drive motor is mounted on the top of the mounting frame.

[0010] Preferably, a first rotating rod is installed at the output end of the drive motor, one end of the first rotating rod is rotatably mounted on the bottom inner wall of the mounting frame, and a drive gear is fixedly installed on the rod body of the first rotating rod.

[0011] Preferably, the outer surface of the annular mounting plate is provided with an external gear ring, which meshes with the drive gear, and a support plate is installed on the upper surface of the barrel.

[0012] Preferably, a second rotating rod is rotatably mounted on one side of the lower surface of the support plate, one end of the second rotating rod is located inside the barrel, a first driven gear is fixedly mounted on the upper side of the second rotating rod, and a second driven gear is also rotatably mounted on one side of the lower surface of the support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Gas can be delivered to the interior of the conveying hood through a gas delivery pipe. The gas can then be delivered to the interior of the barrel through through holes at the bottom and surface of the conveying hood. This allows the gas to be directly delivered to the lower part of the solution inside the barrel, where it can directly mix with the solvent inside the barrel. Driven by a motor, the second rotating rod can be controlled to rotate in the opposite direction to the barrel through the meshing action between the driving gear and the external gear ring, as well as the second driven gear and the first driven gear and the internal gear ring. This allows the first and second stirring rods to stir the solvent at various locations inside the barrel, keeping the solvent in a state of constant positional change. This results in faster solvent-gas fusion, shorter synthesis reaction time, and effectively improved processing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1 , Figure 2 As shown, a synthesis apparatus for preparing lithium phosphate includes a support frame 1 and a barrel 2. The barrel 2 is rotatably mounted on one side of the support frame 1. A drive mechanism 5 is provided on the top of the support frame 1 and the barrel 2. A gas delivery pipe 4 is provided at the center of the upper surface of the barrel 2. A liquid inlet 3 is also provided on one side of the top of the barrel 2. A liquid outlet 6 is provided on one side of the bottom of the barrel 2.

[0024] like Figure 3 , Figure 5 As shown, an annular limiting plate 201 is installed on the outer surface of the barrel 2, and a limiting groove 101 that cooperates with the annular limiting plate 201 is opened on one side surface of the support frame 1. Several first stirring rods 202 are evenly distributed on the inner wall of the barrel 2. A conveying cover 203 is installed on the top inner wall of the barrel 2. Several through holes 204 are opened through the lower outer surface of the conveying cover 203. One end of the gas conveying pipe 4 is located inside the conveying cover 203.

[0025] Gas can be delivered to the interior of the delivery hood 203 through the gas delivery pipe 4. The gas can be delivered to the interior of the barrel 2 through the through holes 204 on the bottom and surface of the delivery hood 203, so that the gas can be directly delivered to the interior of the solvent. Through the cooperation between the annular limiting plate 201 and the limiting groove 101, the position of the barrel 2 on one side of the support frame 1 can be limited, so that the barrel 2 can be rotated and set on one side of the support frame 1.

[0026] like Figures 2 to 5 As shown, the drive mechanism 5 includes a mounting frame 501 and an annular mounting plate 502. The mounting frame 501 is fixedly mounted on the top of the support frame 1, and the annular mounting plate 502 is mounted on the outer side of the upper surface of the barrel 2. A drive motor 503 is mounted on the top of the mounting frame 501, and a first rotating rod 504 is mounted on the output end of the drive motor 503. One end of the first rotating rod 504 is rotatably mounted on the bottom inner wall of the mounting frame 501. A drive gear 505 is fixedly mounted on the rod of the first rotating rod 504. An external gear ring 506 is provided on the outer surface of the annular mounting plate 502, and the external gear ring 506 meshes with the drive gear 505. A support plate 50 is mounted on the upper surface of the barrel 2. 7. A second rotating rod 508 is rotatably mounted on one side of the lower surface of the support plate 507. One end of the second rotating rod 508 is located inside the barrel 2. A first driven gear 509 is fixedly mounted on the upper side of the second rotating rod 508. A second driven gear 510 is also rotatably mounted on one side of the lower surface of the support plate 507. An internal gear ring 511 is provided on the inner surface of the annular mounting plate 502. The second driven gear 510 meshes with the first driven gear 509 and the internal gear ring 511. Several second stirring rods 512 are evenly distributed on the rod of the second rotating rod 508 located inside the barrel 2. The second stirring rods 512 are staggered with the first stirring rod 202.

[0027] Driven by the drive motor 503, the barrel 2 and the second rotating rod 508 can be rotated under the action of the core between the drive gear 505 and the outer gear ring 506, the second driven gear 510 and the first driven gear 509, and the inner gear ring 511. This causes the first stirring rod 202 and the second stirring rod 512 to rotate, which can stir the solvent inside the barrel 2, effectively shorten the time required for the solvent to react with the gas, and improve the processing efficiency.

[0028] The working principle of a synthesis apparatus for preparing lithium phosphate:

[0029] In use, the solution is added to the inside of the barrel 2 through the liquid inlet 3, and then gas is added to the inside of the barrel 2 through the gas delivery pipe 4, so that the gas and solution are mixed and a synthesis reaction takes place. The end of the gas delivery pipe 4 is located inside the delivery cover 203, which allows the gas to be directly delivered to the lower part of the solution inside the barrel 2, where it is directly mixed with the solvent inside the barrel 2. The first rotating rod 504 is driven to rotate by the drive motor 503. Under the meshing action between the drive gear 505 and the external gear ring 506, the rotation of the first rotating rod 504 will drive the barrel 2 to rotate. The annular mounting plate 502 on the top of the barrel 2... The second driven gear 510 will rotate, and under the meshing action between the second driven gear 510, the first driven gear 509, and the internal gear ring 511, the second rotating rod 508 can be controlled to rotate. The second rotating rod 508 rotates in the opposite direction to the barrel 2, which can make the first stirring rod 202 and the second stirring rod 512 inside the barrel 2 rotate in opposite directions, so that the solvent at various positions inside the barrel 2 can be stirred, so that the solvent is always in a state of position change, the solvent and gas fusion speed is faster, the synthesis reaction time is shorter, and the processing efficiency can be effectively improved. After the reaction is completed, the liquid can be discharged through the liquid outlet 6 at the bottom.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
