Problems solved by technology

The amount of defoamer added cannot be controlled, and during the dispersion process, as the dispersion time prolongs, the defoamer is easy to volatilize, and the defoaming effect is poor. The defoaming effect is greatly reduced

Abstract

The invention discloses an automatic defoaming agent adding device for dispersing conductive slurry of a carbon nano-tube. The device comprises a vertical grinding barrel, wherein a controller is arranged at the bottom of the vertical grinding barrel, and a timer is arranged in the controller; an S-shaped circulating water pipe uniformly winds the periphery of the side wall of the vertical grinding barrel; the vertical grinding barrel is filled with conductive slurry of a carbon nano-tube, a liquid level sensor and a temperature sensor; a defoaming agent storage tank is arranged above the vertical grinding barrel, and a liquid outlet directing to the inside of the vertical grinding barrel is formed in the bottom of the defoaming agent storage tank; an electromagnetic valve and a flow sensor are arranged on the liquid outlet; and the opening degree of the electromagnetic valve can be adjusted, and the flow sensor is used for detecting the flow rate of the defoaming agent flowing in the vertical grinding barrel. According to the device, the defoaming agent can be automatically added in the dispersing process, the adding amount of the defoaming agent can be automatically determined according to the liquid level and temperature of the conductive slurry of the carbon nano-tube, and heat generated in the dispersing process can be automatically controlled.

Description

technical field [0001] The application relates to an auxiliary inspection device in the production process of carbon nanotube slurry, in particular to an automatic defoamer adding device for dispersing carbon nanotube conductive slurry. Background technique [0002] As a one-dimensional nanomaterial, carbon nanotubes are light in weight, perfectly connected in a hexagonal structure, and have many unusual mechanical, electrical, and chemical properties. [0003] Carbon nanotubes have good mechanical properties. The tensile strength of CNTs reaches 50-200GPa, which is 100 times that of steel, but the density is only 1 / 6 of steel, which is at least an order of magnitude higher than that of conventional graphite fibers; its elastic modulus can reach 1TPa , equivalent to the modulus of elasticity of diamond, about 5 times that of steel. For carbon nanotubes with a single-walled ideal structure, the tensile strength is about 800 GPa. Although the structure of carbon nanotubes is...
