A graphene powder preparation system for carbon nanotube slurry preparation

Abstract

The invention relates to a graphene powder preparation system for carbon nanotube slurry preparation, which includes a grinding device, a conveying device and a drying device. The drying device includes a drying cylinder and a water tank. There is a material guide plate, and the material guide plate is set up in a spiral shape; a heating box is installed on the side wall of the drying cylinder, and an induced draft fan and an electric heater are installed in the heating box. An electric heater is installed on the pipe, and the other end of the air outlet pipe runs through the heating box and the drying cylinder and is located above the material guide plate; the water tank is set on one side of the drying cylinder, and a water pump is installed on the water tank, and the water pump is connected to the water tank through a pipeline. The output end of the water pipe is connected with a water delivery pipe, and one end of the water delivery pipe is connected with the top of the drying cylinder and an atomizing nozzle is connected with the top of the inner wall of the drying cylinder. Under the action of the material guide plate, the graphene powder rolls down along the material guide plate, which increases the drying time of the graphene powder.

Description

technical field [0001] The invention belongs to the technical field of conductive slurry preparation, and in particular relates to a graphene powder preparation system for carbon nanotube slurry preparation. Background technique [0002] As a new type of green energy, lithium-ion batteries are widely used in power systems for digital products, electric vehicles, and national defense and military equipment due to their advantages such as high capacity, high voltage, small size and light weight, long cycle life, good safety, and no memory effect. , and photovoltaic energy storage systems and many other fields.

Problems solved by technology

The equipment in the existing graphene powder preparation system has poor grinding effect during grinding, and there will still be large particle agglomeration in the graphene slurry, and a separate grinding disc is used for grinding, and the grinding efficiency is low; and the existing The internal structure of the dryer is simple. When drying the graphene slurry, the graphene slurry cannot be fully dried, and a small amount of insufficiently dried graphene powder will fall directly into the collection box under the action of gravity, thereby Affect the quality of graphene powder
