Description

Technical Field

[0001] This utility model relates to the field of stirring devices, and more specifically, to a powerful stirring device for the production of graphene-modified carbon fiber brake pads. Background Technology

[0002] Graphene-modified carbon fiber brake pads are high-performance composite brake pads. They significantly improve overall performance by introducing graphene nanomaterials into a traditional carbon fiber reinforced matrix. Graphene, with its excellent strength, thermal conductivity, and lubrication properties, effectively enhances the wear resistance, heat dissipation efficiency, and braking stability of brake pads, making it particularly suitable for extreme conditions such as high speed and high load. The preparation of graphene requires a mixer because nano-graphene particles are prone to agglomeration, and chopped carbon fibers are easily unevenly distributed. Therefore, a mixer is needed to forcibly break up the graphene agglomerates and uniformly disperse them along with the carbon fibers into the resin matrix, forming a homogenized composite slurry.

[0003] A prior art mixing and stirring device for graphene production, disclosed in CN119524788A, includes a reaction tank, a shell, and a rotating mixing structure. The rotating mixing structure achieves stirring of the materials inside the reaction tank. However, this stirring device only has one reaction tank, and the entire process requires feeding, stirring, unloading, and cleaning before feeding can begin again. In other words, the next batch of materials cannot be stirred until the current batch is completely stirred. This results in significant waiting or downtime, low equipment utilization, and overall low production efficiency, failing to meet the demands of modern large-scale, continuous production. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide a powerful stirring device for the production of graphene-modified carbon fiber brake pads.

The rotating disk has multiple working positions. Each working position is equipped with a positioning plate fixedly connected to the rotating disk, a tank located inside the positioning plate, a cover that can close the tank, and a lifting unit that can drive the cover to rise and fall. The side wall of the tank has a sandwich layer with a spiral pipe inside. The tank has an inlet and an outlet that are respectively connected to the two ends of the spiral pipe. The multiple working positions include a feeding position, a stirring position, and two storage positions. The cover located at the stirring position is a stirring cover. A stirring motor is installed at the stirring cover. The stirring motor drives a rotating shaft. The rotating shaft is connected to a stirring paddle that can extend into the tank.

[0012] Furthermore, each connecting plate has multiple guide rods, and each cover has multiple fixing sleeves, with each guide rod corresponding to a fixing sleeve.

[0013] This allows the lifting platform to rise and fall stably.

[0014] Furthermore, the top of the lifting plate has a lifting lug, and the movable end of the electric telescopic rod is fixedly connected to the lifting lug by bolts and nuts.

[0015] This facilitates the fixed connection between the electric telescopic pole and the lifting platform.

[0016] Furthermore, the inner side of the stirring cover has a sealing groove, and a sealing ring is provided in the sealing groove, and the top of the tank can be accommodated in the sealing groove.

[0017] This achieves a better sealing effect.

[0018] Furthermore, a plurality of first reinforcing ribs are provided between the mounting plate and the main support rod.

[0019] This ensures a stable connection between the mounting plate and the main support.

[0020] Furthermore, multiple second reinforcing ribs are provided between the fixed plate and the main support rod.

[0021] This ensures a stable connection between the fixed plate and the main support.

[0022] Furthermore, the mounting plate has multiple fixing holes.

When the mixing position is in the mixing position, hot water is introduced to heat the material and promote mixing. When the storage position is in the storage position, cold water is introduced to cool the material and facilitate material preservation. Nitrogen gas can be injected into the storage position to form protection and effectively prevent the material from oxidizing during storage. Attached Figure Description

Multiple first reinforcing ribs 5.1 are provided between the mounting plate 4 and the main support rod 5, and multiple second reinforcing ribs 5.2 are provided between the fixed plate 3 and the main support rod 5.

[0042] Working principle: The mixing device of this application is fixedly installed on the frame or other fixed device by the mounting plate. The drive unit can drive the rotating disk to rotate, thereby realizing the switching of working positions. This allows the feeding, mixing and storage processes to be carried out continuously, thereby significantly improving production efficiency.

[0043] Specifically, before mixing, the lifting unit first drives the corresponding cover to rise (for ease of description, the tanks at the initial positions of the feeding position, mixing position, and two storage positions are referred to as tank A, tank B, tank C, and tank D, respectively). Then, the raw materials to be mixed are placed into tank A. After loading, the drive unit drives the rotating disk to rotate, positioning tank A at the mixing position. At this time, tanks B and C are positioned at the two storage positions, and tank D is positioned at the feeding position. Next, the mixing cover at the mixing position is lowered to close tank A, and hot water is introduced into the inlet of tank A to heat the materials. Then, the mixing motor is started to mix the materials in tank A. During mixing, materials can be added to tank D. After mixing is complete, the mixing motor is turned off, and the mixing cover is raised. Then, the rotating disk is driven to rotate, positioning tank A at the upstream storage position. At this time, tank B is positioned at the downstream storage position, tank C is positioned at the feeding position, and tank D is positioned at the mixing position. If the material has not yet been used downstream, it can be temporarily stored at the storage location. Specifically, the cover at the storage location is lowered to close tank A, and cold water is introduced into the inlet of tank A to facilitate the preservation of the mixed material.

[0044] Next, the mixing cover is closed to seal tank D, and the mixing motor is started to mix the material inside tank D. While mixing, material can be added to tank C. After mixing is complete, the mixing motor is turned off, and the mixing cover is raised. Then, the rotating disc is driven to rotate, positioning tank A at the downstream storage position. At this point, tank B is at the feeding position, tank C is at the mixing position, and tank D is at the upstream storage position. If the downstream area is not yet in use, the mixed material can be temporarily stored at the storage position. Specifically, the cover at this storage position is lowered to close tank D, and cold water is introduced into the inlet of tank D to facilitate the preservation of the mixed material.

[0045] Next, the material in tank C is stirred following the steps above. This process is repeated to form a continuous production line. While the stirred material awaits transport to the next production stage, the two storage locations can simultaneously store two batches of material. Furthermore, when the material is in a storage location, nitrogen gas can be injected into the tank via a hose connected to the tank's air inlet, which helps to better preserve the stirred material and prevent oxidation. When unloading is required, the tank can be removed from the storage location and replaced with an empty tank.

[0046] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
