Description

Technical Field

[0001] The invention relates to the technical field of graphite production, in particular to a rotating disc centrifugal vibrating screening device for graphite production and a screening method thereof. Background Art

[0002] As an important non-metallic mineral material, graphite is widely used in batteries, coatings, metallurgy, chemical industry and other fields. In the graphite production process, screening is a key step to ensure the quality and performance of graphite products, so it is usually necessary to vibrate and screen graphite powder or granular graphite samples. The purpose of this step is to screen and remove dust from the raw materials, and remove a large amount of fine powder and impurities generated after crushing and ore crushing processes to ensure the purity and quality of graphite. At the same time, vibration screening is also used in the grading process of graphite powder. According to the different particle sizes, corresponding grades are formed on the screen, because the particle size of graphite powder is one of the key factors determining its physical and chemical properties.

[0003] Most of the existing rotating disc centrifugal vibrating screening machines for graphite production have simple structures. They directly use motors to drive the deflection hammer to rotate, thereby driving the screen plate to shake. Under the action of centrifugal force, the graphite powder moves on the surface of the screen plate, thereby performing screening. However, due to the limited shaking amplitude of the screen plate, and the existing rotating disc centrifugal vibrating screening machines for graphite production often find it difficult to effectively break the adhesion and agglomeration between graphite powder particles, it is easy to cause uneven distribution of graphite powder on the screen plate, affecting the accuracy and efficiency of screening. In addition, due to the adhesion and agglomeration of materials, it is easy to cause clogging of the screen holes, reducing the permeability of the screen plate, further affecting the screening effect. In response to the above problems, the present invention document proposes a rotating disc centrifugal vibrating screening device for graphite production. Summary of the invention

[0019] S1. When the operator uses the centrifugal vibrating screen body to screen the graphite powder, the motor is directly turned on first. The motor drives the eccentric weight and the rotating shaft to rotate. The rotating shaft drives the first rotating base and the second rotating base to rotate through the diamond column, so that the first rotating base drives the rubber impact ball to rotate through the first connecting plate, and the second rotating base drives the second connecting plate, the protective plate and the beating stick to rotate.

In addition, the impact of the graphite powder can also help clean the sieve holes, reduce blockage, maintain good permeability of the sieve plate, and further improve the screening effect.

[0024] 2. The rotating disk centrifugal vibrating screening device for graphite production is provided with a breaking structure.

During the rapid rotation of the breaking rod, it can impact the damp graphite powder on the surface of the screening plate, thereby breaking up the damp graphite powder, making the graphite powder particles finer and more fluid, which helps to reduce the accumulation and blockage of graphite powder in the screening process, and once again ensure the screening effect.

[0025] 3. The rotating disk centrifugal vibrating screening device for graphite production is provided with a cleaning structure. When the centrifugal vibrating screen body screens the graphite powder and the screening plate needs to be cleaned, the motor is still turned on. When the rubber impact ball hits the screening plate, the material stuck inside the screening plate can be discharged, and the operator can adjust the electric push rod so that the movable rod of the electric push rod pushes the rotating disk to move closer to the motor.
