Description

Technical Field

[0001] This utility model belongs to the field of carbon-containing composite material production technology, and in particular relates to a carbon-containing composite material production device. Background Technology

[0002] In recent years, graphite anode materials have become the mainstream choice in the lithium-ion battery market due to their excellent electrochemical performance. However, in practical applications, surface modification is still needed to further improve their performance. During the anode material modification process, it is usually necessary to dissolve polymeric coating materials such as asphalt and resin in an organic solvent to prepare a coating solution, which is then stirred and mixed with graphite anode material powder to form a uniform thin film or coating on the surface of the anode material to construct a composite material system. When combining the coating material with the graphite anode material powder, thorough stirring and heating are required. The coating solution has a certain viscosity; if the stirring is uneven, it can easily lead to uneven coating and affect the coating effect. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a production device for carbon-containing composite materials.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The mixing chamber is equipped with heating wires inside its side wall;

[0007] The mixing chamber is equipped with a first rotating shaft that rotates within it, and the first rotating shaft is coaxially arranged with the mixing chamber.

[0008] The first stirring rods are evenly arranged in a circular array on the side of the first rotating shaft, and the first stirring rods are evenly distributed in a linear array along the axis of the first rotating shaft.

[0009] The mixing chamber is equipped with a second rotating shaft, and four second rotating shafts are evenly distributed in a circular array around the center of the first rotating shaft.

[0010] The second rotating shaft has a second stirring rod evenly arranged in a circumferential array on its side, and the second stirring rod is evenly distributed in a linear array along the axis of the second rotating shaft;

[0011] The second stirring rod is staggered with the first stirring rod, and the second stirring rods adjacent to the second rotating shaft are staggered;

[0013] The mixing chamber is equipped with a first scraper that rotates inside, and one side of the first scraper abuts against the inner wall of the mixing chamber.

[0014] The mixing chamber is equipped with a drive assembly on top, which is used to drive the first rotating shaft, the second rotating shaft and the scraper to rotate.

[0015] Through the above technical solution, the graphite material and the coating material enter the mixing box from the feed pipe. The heating wires in the inner wall of the mixing box and the heating wires in the first rotating shaft, the second rotating shaft, the first stirring rod and the second stirring rod heat the material in the mixing box. The staggered first stirring rod and the second stirring rod, as well as the adjacent staggered second stirring rods, can mix the material evenly, so that the coating material can better coat the negative electrode material. The first scraper scrapes the inner wall of the mixing box to prevent the coating material from sticking to the inner wall of the mixing box.

[0016] Furthermore, both the first and second stirring rods are provided with heat-conducting strips, which are arranged vertically, with one end of the heat-conducting strip extending into the first and second stirring rods and connected to the heating wire.

[0023] A motor is provided on the top of the mounting cover, and the output end of the motor extends into the mounting cover and is connected to the first gear.

[0024] Through the above technical solution, the motor drives the first gear to rotate, which in turn drives the second gear to rotate. The first gear drives the first shaft to rotate, and the second gear drives the second shaft to rotate, thereby driving the first stirring rod and the second stirring rod to mix the materials in the mixing box.

[0025] Furthermore, a third gear is coaxially mounted on one of the second gears;

[0029] Furthermore, the mounting cover is provided with multiple fixing blocks, the top of the fixing blocks is fixedly connected to the top of the mounting cover, and the bottom of the fixing blocks is fixedly connected to the top of the mixing box.

[0033] Using the above technical solution, the coated graphite anode material is discharged from the discharge pipe.

[0034] Furthermore, a second scraper is provided at the bottom of the second rotating shaft. The lower end of the second scraper is triangular, and the second scraper abuts against the bottom of the mixing tank.

[0035] Through the above technical solution, the material can be discharged more effectively during the rotation of the second rotating shaft.

[0036] This utility model has the following beneficial effects:

[0037] Graphite material and coating material enter the mixing chamber through the feed pipe. The heating wires in the inner wall of the mixing chamber and the heating wires in the first and second rotating shafts, the first stirring rod and the second stirring rod heat the material in the mixing chamber. The staggered first and second stirring rods and the adjacent staggered second stirring rods can mix the material evenly, so that the coating material can better coat the negative electrode material.

A drive assembly is provided at the top of the mixing chamber 1 to drive the first rotating shaft 2, the second rotating shaft 3, and the scraper to rotate.

The staggered arrangement of the first stirring rod 21 and the second stirring rod 31, as well as the adjacent staggered arrangement of the second stirring rod 31, can mix the materials evenly, so that the coating material can better coat the negative electrode material. The first scraper 4 scrapes the inner wall of the mixing chamber 1 to prevent the coating material from sticking to the inner wall of the mixing chamber 1.

[0053] Specifically, the drive assembly includes a mounting cover 6, which is located on top of the mixing chamber 1; a first gear 61 is rotatably mounted inside the mounting cover 6, and a second gear 62 is located around the periphery of the first gear 61; four second gears 62 mesh with the first gear 61, and the second gears 62 are rotatably mounted inside the mounting cover 6; the top of a first rotating shaft 2 extends out of the mixing chamber 1 and is connected to the first gear 61; the top of a second rotating shaft 3 extends out of the mixing chamber 1 and is connected to the second gear 62; a motor 64 is located on the top of the mounting cover 6, and the output end of the motor 64 extends into the mounting cover 6 and is connected to the first gear 61, with a third gear 63 coaxially mounted on one of the second gears 62; a gear ring 65 is rotatably mounted inside the mounting cover 6, and the gear ring 65 meshes with the first gear 61.

At the same time, the rotation of the second gear 62 drives the third gear 63 to rotate, thereby driving the gear ring 65 to rotate, thereby driving the first scraper 4 to rotate along the inner wall of the mixing box 1 and scrape.

[0054] Specifically, the discharge pipe 12 is coaxially arranged with the mixing box 1.

During the rotation of the second rotating shaft 3, the second scraper 32 can better discharge the material.

[0055] The working principle of this utility model is as follows: Graphite material and coating material enter the mixing chamber 1 through the feed pipe 11.

The motor 64 drives the first gear 61 to rotate, thereby driving the second gear 62 to rotate. The first gear 61 drives the first rotating shaft 2 to rotate, and the second gear 62 drives the second rotating shaft 3 to rotate. The staggered arrangement of the first stirring rod 21 and the second stirring rod 31, as well as the adjacent staggered arrangement of the second stirring rod 31, can mix the material evenly, so that the coating material can better coat the negative electrode material. The heat-conducting strip 5 can stir in the longitudinal direction. At the same time, the rotation of the second gear 62 drives the rotation of the third gear 63, thereby driving the gear ring 65 to rotate, thereby driving the first scraper 4 to rotate along the inner wall of the mixing chamber 1 and scrape off the material. After the coating is completed, under the drive of the second rotating shaft 3, the second scraper 32 can better scrape the material to the opening of the discharge pipe 12 for discharge.
