Description

Technical Field

[0001] This utility model relates to the field of chemical drying equipment technology, and in particular to a drying device for drying lithium carbonate. Background Technology

[0002] Lithium carbonate, as an important basic chemical raw material, is widely used in lithium batteries, ceramics, glass, pharmaceuticals, and metallurgy, among other fields. Its product quality directly affects the performance and stability of downstream industries. In the production process of lithium carbonate, drying is one of the key post-processing steps, primarily used to remove moisture from the material to ensure it meets the specified moisture content standards. The effectiveness of drying not only affects the purity, flowability, and storage stability of the product but also influences the smooth progress of subsequent processing techniques.

[0003] However, existing lithium carbonate drying equipment still has many shortcomings in practical applications. Traditional drying devices generally suffer from uneven drying, and the material is prone to clumping and adhesion on the inner wall of the cylinder or in dead corners. This not only affects heat transfer efficiency and reduces drying effect, but also leads to incomplete discharge, resulting in material residue and waste.

[0004] Therefore, it is necessary to design a drying device for lithium carbonate drying to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of materials easily clumping and adhering on the cylinder wall or in dead corners, which leads to reduced drying efficiency and difficulty in complete discharge, resulting in material residue and waste, this utility model provides a drying device for lithium carbonate drying.

[0006] Technical solution: A drying device for lithium carbonate drying includes a base plate, a drying cylinder, a connecting frame, a controller, and a feeding hopper. The drying cylinder is fixedly connected to the top of the base plate, the connecting frame is fixedly connected to the right side of the top of the base plate, the controller is fixedly connected to the front side of the connecting frame, and the feeding hopper is fixedly connected to the top of the connecting frame. The feeding hopper is connected and communicates with the drying cylinder. The device also includes a support block, a servo motor, a drive shaft, a feeding screw, and stirring blades. The support block is fixedly connected to the right side of the connecting frame, the servo motor is fixedly connected to the top of the support block, the servo motor is electrically connected to the controller, and the drive shaft is fixedly connected to the output shaft of the servo motor. The drive shaft passes through the connecting frame and extends into the interior of the drying cylinder. The portion of the drive shaft inside the drying cylinder is fixedly connected to the feeding screw and stirring blades. The feeding screw is arranged axially, and the stirring blades are evenly distributed in the gaps between the feeding screws.

[0007] In addition, it is particularly preferred that the device also includes a hot air generator and an air duct, with the hot air generator fixedly connected to the bottom of the connecting frame, the hot air generator being electrically connected to the controller, and the air outlet of the hot air generator being connected and communicated with the hot air inlet on the side wall of the drying cylinder through the air duct.

[0008] In addition, it is particularly preferred that the device also includes a sealing cover and an exhaust pipe, with the sealing cover slidably connected to the left side of the drying cylinder, and the front and rear sides of the sealing cover being connected and connected to exhaust pipes, which are in communication with the inside of the cylinder.

[0009] In addition, preferably, it also includes a discharge frame, a connecting frame, a fan, an observation window, a storage drawer, and a dust collection box. The discharge frame is connected and communicates with the bottom left side of the drying cylinder. The connecting frame is fixedly connected to the bottom left side of the drying cylinder.

Dust discharge ports are respectively opened at corresponding positions on the front side of the connecting frame and the rear side of the dust collection box.

[0010] In addition, it is particularly preferred that the observation window is made of a transparent material.

[0011] In addition, it is particularly preferred that the surface of the stirring blades is coated with a polytetrafluoroethylene non-stick coating.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention sets a feeding screw and a stirring blade in a coordinated structure on the transmission shaft, and sprays a polytetrafluoroethylene anti-stick coating on the surface of the stirring blade to prevent lithium carbonate from clumping and adhering on the cylinder wall or dead corners during the drying process. This effectively improves the uniformity of material turning and the continuity of drying, reduces material residue, and improves the integrity of the discharge.

[0013] 2. This utility model uses a hot air generator and air duct to evenly introduce high-temperature airflow into the drying cylinder. Combined with the axial conveying action of the feeding screw on the material, it achieves the effect of full contact between the material and the hot air, so that the moisture evaporates quickly and the drying efficiency is improved. At the same time, the cooperation between the sealing cover and the exhaust pipe ensures the airtightness of the drying environment, which is conducive to controlling the stability of the drying process.

[0014] 3. This utility model activates the fan on the rear side of the connecting frame during the discharge stage, using airflow to blow the fine dust remaining in the discharge frame and connecting channel through the dust discharge port to the dust collection box.

The front side of the connecting frame 3 is connected to the controller 4 by screws. The top of the connecting frame 3 is connected to the feeding hopper 5 by screws. The feeding hopper 5 is connected to and communicates with the drying cylinder 2. The device also includes a support block 6, a servo motor 7, a drive shaft 8, a feeding screw 9, and stirring blades 10. The right side of the connecting frame 3 is connected to the support block 6 by screws. The top of the support block 6 is connected to the servo motor 7 by screws. The servo motor 7 is electrically connected to the controller 4. The output shaft of the servo motor 7 is fixedly connected to the drive shaft 8. The drive shaft 8 passes through the connecting frame 3 and extends into the interior of the drying cylinder 2. The part of the drive shaft 8 located inside the drying cylinder 2 is fixedly connected to the feeding screw 9 and the stirring blades 10. The feeding screw 9 is arranged axially. The stirring blades 10 are evenly distributed in the gaps between the feeding screw 9. The surface of the stirring blades 10 is coated with a polytetrafluoroethylene anti-stick coating.

[0022] like Figure 2 and Figure 3 As shown, it also includes a hot air generator 11, an air duct 12, a sealing cover 13, and an exhaust pipe 14. The bottom of the connecting frame 3 is connected to the hot air generator 11 by screws. The hot air generator 11 is electrically connected to the controller 4. The air outlet of the hot air generator 11 is connected to and communicates with the hot air inlet on the side wall of the drying cylinder 2 through the air duct 12. The sealing cover 13 is slidably connected to the left side of the drying cylinder 2. The front and rear sides of the sealing cover 13 are connected to and communicate with the exhaust pipe 14. The exhaust pipe 14 communicates with the inside of the cylinder.

[0023] like Figure 4 and Figure 5 As shown, it also includes a discharge frame 15, a connecting frame 16, a fan 17, an observation window 18, a storage drawer 19, and a dust collection box 21. The discharge frame 15 is connected and communicated with the bottom left side of the drying cylinder 2. The connecting frame 16 is connected to the bottom left side of the drying cylinder 2 by screws. The fan 17 is connected to the rear side of the connecting frame 16 by screws.

[0026] When the set drying time is reached, the controller 4 automatically stops the servo motor 7 and the hot air generator 11, the equipment stops, and the dried material is discharged under gravity and falls directly into the storage drawer 19 below for easy collection and transfer. The entire device achieves efficient, uniform, sealed and low-loss drying of lithium carbonate material through the coordinated operation of its components.
