Description

Technical Field

[0001] This utility model belongs to the field of battery cathode material processing technology, and in particular relates to a high-efficiency water washing and drying equipment for cathode materials. Background Technology

[0002] Moisture in batteries can affect their performance, such as causing electrolyte deterioration, reacting with the electrolyte to produce harmful gases, increasing internal pressure, deformation, high internal resistance, high self-discharge, low capacity, poor cycle life, and even leakage. Therefore, it is necessary to control the moisture content to an extremely low level through drying, generally requiring a moisture content of (100 to 300) × 10⁻⁻⁻⁶. 6 Between ppm, heated air is used as the drying medium, and heat is transferred to the material through convection, causing the moisture in the material to evaporate. This method is suitable for drying most battery materials, but it still has the following drawbacks in practical use:

[0003] In the drying process of positive electrode materials, the battery positive electrode materials are directly dried using drying equipment. During the drying process, the positive electrode materials flow in the fluidized bed. However, during the flow, the pressure is different at different locations in the hot air conveying process. The material is prone to clogging the pores of the fluidized bed during the conveying process, which affects the drying effect of the material.

[0004] Secondly, after the dried material is discharged from the entire drying equipment, an additional collection hopper is needed to collect the dried material. During operation, the material is easily blown out by the airflow during the output process, making collection inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency water washing and drying equipment for cathode materials. By setting up a support chamber, a sealing plate and a support plate, it solves the problems that the material is easily blocked in the air outlet pores during material conveying, which affects the drying effect of the material, and that the material is not sufficiently separated from the airflow during output.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a high-efficiency water washing and drying device for positive electrode materials, comprising a support chamber, a sealing plate, and a support plate. An air inlet pipe is fixedly connected to the lower part of one end of the support chamber, and equally spaced heating components are fixed inside the air inlet pipe. The bottom of the support chamber is arc-shaped, and a discharge pipe is fixedly connected to the bottom edge of the support chamber away from the air inlet pipe. A sealing plate is fixedly fixed to the top of the support chamber, and an air outlet sleeve is fixedly fixed through one short side of the sealing plate. Support plates are symmetrically fixed to both sides of the support chamber. During operation, a fluidized bed is fixed within the support chamber. After hot air enters the support chamber below the fluidized bed, it passes through the fluidized bed, drying the battery positive electrode material passing over the surface of the fluidized bed. The sealing plate seals the top of the support chamber through a fixed connection, and the support plate provides support for the support chamber on the support spring.

[0008] Furthermore, a vibration motor is fixed to the upper part of both sides of the support chamber. The vibration motor is located above the support plate and drives the support chamber to vibrate.

[0009] Furthermore, an inclined fluidized bed is fixed inside the support chamber, and a baffle is fixed at the lower end of the fluidized bed. The baffle is fixed to the inner wall of the support chamber, and the discharge pipe is located on the side of the baffle away from the fluidized bed. The fluidized bed on the support chamber is connected to the baffle, and the baffle separates the space for air supply in the fluidized bed from the space for material discharge in the support chamber.

[0010] Furthermore, an air filter element is fixed inside the air outlet sleeve, and the air filter element is located above the discharge pipe. The air filter element inside the air outlet sleeve performs exhaust filtration.

[0011] Furthermore, a conveying pipe is fixedly installed inside the sealing plate at a position symmetrical to the air outlet sleeve. A corrugated pipe is fixedly connected to the top end of the conveying pipe, and an inlet pipe is fixedly connected to the top end of the corrugated pipe. The inlet pipe conveys the material into the corrugated pipe and then into the support chamber.

[0012] Furthermore, support springs are symmetrically fixed to the bottom of the support plate, and support seats are fixed to the bottom ends of the two support springs at the bottom of the same support plate. The support plate is supported by the cooperation of the support springs and the support seats.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of clogged air vents affecting the drying effect in high-efficiency water washing and drying equipment for cathode materials by setting up a support chamber and a sealing plate. The vibration motor drives the support chamber to vibrate, while the material is conveyed into the support chamber. Air is also conveyed into the support chamber through an air inlet pipe. After being heated by the heating element, the air is conveyed to the fluidized bed below the support chamber. Simultaneously, the vibration motor drives the support chamber and the fluidized bed to vibrate as the material is conveyed onto the fluidized bed. The hot air dries the material while it vibrates, allowing it to dry simultaneously with the air vents from the fluidized bed. This results in a smoother material conveying process in the high-efficiency water washing and drying equipment for cathode materials, reducing the likelihood of clogged air vents and improving the drying effect.

[0015] This invention solves the problem of insufficient separation between the positive electrode material and the airflow during output by setting up a support chamber, a sealing plate, and a support plate. The material is conveyed from the feed pipe to the corrugated pipe, then to the conveying pipe, and finally to the support chamber. As the fluidized bed vibrates, the positive electrode material flows and dries on the fluidized bed. During the flow, hot air fully dries the material. When the material flows to the baffle and then to the discharge pipe, the air rises into the air outlet sleeve and is filtered by the air filter element inside the air outlet sleeve. During operation, this allows for sufficient separation between the airflow and the positive electrode material, effectively preventing the material from being discharged with the airflow.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-4 This utility model relates to a high-efficiency water washing and drying device for positive electrode materials, comprising a support chamber 1, a sealing plate 2, and a support plate 3. An air inlet pipe 101 is fixedly connected to the lower part of one end of the support chamber 1. The support chamber 1 transports the washed positive electrode material. The end of the air inlet pipe 101 away from the support chamber 1 is connected to an air conveying device. Heating components 1011 with equal spacing are fixed inside the air inlet pipe 101. When air passes through the air inlet pipe 101, it is heated by the heating components 1011. The bottom of the support chamber 1 is... The support chamber 1 is designed in an arc shape. A discharge pipe 103 is fixedly connected to the bottom edge of the support chamber 1, which is away from the air inlet pipe 101. The discharge pipe 103 outputs the dried positive electrode material from the support chamber 1. A sealing plate 2 is fixedly fixed to the top of the support chamber 1, which seals the top of the support chamber 1. An air outlet sleeve 201 is fixedly fixed through one short side of the sealing plate 2. The top of the air outlet sleeve 201 is connected to the exhaust device to exhaust the air from the support chamber 1. Support plates 3 are symmetrically fixed on both sides of the support chamber 1, and the support plates 3 provide support for the support chamber 1.

[0027] Specifically, a vibration motor 104 is fixed on the upper part of both sides of the support chamber 1. The vibration motor 104 is located above the support plate 3. When the support chamber 1 is working, the vibration motor 104 drives the support chamber 1 to vibrate.

[0028] Furthermore, an inclined fluidized bed 105 is fixed inside the support chamber 1. A baffle 102 is fixed at the lower end of the fluidized bed 105. The baffle 102 is fixed to the inner wall of the support chamber 1. The discharge pipe 103 is located on the side of the baffle 102 away from the fluidized bed 105. When the support chamber 1 is working, the material enters it, flows through the fluidized bed 105, and is dried by the fluidized bed 105. When the baffle 102 is working, it separates the drying airflow area of ​​the fluidized bed 105 from the material output area of ​​the discharge pipe 103, and initially separates the air and the dried material.

[0029] The operation process of this embodiment is as follows: During operation, the vibration motor 104 is started, and the vibration motor 104 drives the support chamber 1 to vibrate. At the same time, the material is conveyed into the support chamber 1, and air is conveyed into the support chamber 1 through the air inlet pipe 101. After being heated by the heating component 1011, the air is conveyed to the fluidized bed 105 in the support chamber 1. The material is conveyed onto the fluidized bed 105 in the support chamber 1. At the same time, the vibration motor 104 is started, and the vibration motor 104 drives the support chamber 1 and the fluidized bed 105 to vibrate. As the air is conveyed onto the fluidized bed 105, the hot air dries the material. After drying, the material flows into the discharge pipe 103, so that the material is fully dried as it flows through the support chamber 1 during operation. Specific Implementation Example 2

[0030] Please see Figure 1-6 Based on the first specific embodiment, an air filter element 202 is fixed inside the air outlet sleeve 201. The air filter element 202 is located above the discharge pipe 103. When the air outlet sleeve 201 is working, the air is filtered by the air filter element 202 to reduce pollution.

[0031] Specifically, a conveying pipe 203 is fixedly installed in the sealing plate 2 at a position symmetrical to the vent sleeve 201.

The top end of the feed pipe 205 is connected to the equipment for conveying battery positive electrode material. The battery positive electrode material is conveyed into the feed pipe 205, then transferred through the corrugated pipe 204, and finally conveyed into the conveying pipe 203, and finally conveyed onto the fluidized bed 105 in the support chamber 1.

[0032] Furthermore, support springs 301 are symmetrically fixed at the bottom of the support plate 3. The bottom ends of the two support springs 301 at the bottom of the same support plate 3 are jointly fixed to the support seat 302. The support plate 3 fixes the support springs 301 at its bottom end. The support springs 301 support the support plate 3 on the support seat 302 and are supported on the ground by the support seat 302.

[0033] The operation process of this embodiment is as follows: During operation, the material is conveyed from the feed pipe 205 to the corrugated pipe 204, then to the conveying pipe 203, and finally to the support chamber 1. As the fluidized bed 105 vibrates, the positive electrode material flows and dries on the fluidized bed 105. During the flow, hot air dries the material thoroughly. When the material flows to the baffle 102 and then to the discharge pipe 103, the air rises into the air outlet sleeve 201 and is filtered by the air filter element 202 inside the air outlet sleeve 201. During operation, the airflow and the positive electrode material are fully separated, effectively preventing the material from being discharged with the airflow.
