Mixing and kneading device

Abstract

The invention discloses a mixing and kneading device which consists of a pot cover, a pot body, a stirring shaft, a ceramic heating sleeve, an exhaust pipeline and a belt conveyor, wherein the stirring shaft is arranged in the center of the pot cover in a penetrating way; the pot cover is provided with a feeding hole, an infrared thermometer and the exhaust pipeline; the stirring shaft is provided with a stirring paddle; the mixing and kneading device is characterized in that a pot wall is internally provided with a cooling water pipeline; the surface of the pot body is provided with a ceramic heating sleeve; the surface of the ceramic heating sleeve is provided with a heat insulation layer; a discharge hole is formed in the bottom of the pot body; the belt conveyor is arranged under the discharge hole; the exhaust pipeline is connected with a condenser; and the lower end of the condenser is connected with a receiving tank. After the mixing and kneading device is adopted, a bonding agent can be evenly distributed on the surfaces of dry particles, so that the performances of fine-structure carbon products can be improved; and furthermore, the operations including heating, mixing and kneading and cooling can be carried out on a material at the same time, so that the equipment input can be reduced.

Description

technical field [0001] The invention relates to a kneading device, in particular to a kneading device used in the production field of fine-structure carbon products, and the invention can also be applied to other industries. Background technique [0002] In the production process of carbon products, kneading operation is required to make the coke material and binder material mix evenly. The traditional kneading process has four steps: material preheating, dry mixing, wet mixing, and cooling. The material heating needs to be equipped with a special heating system according to the type of material, such as asphalt heat medium system and dry material heater. After being heated to the set temperature, the material needs to be put into the kneading pot for dry mixing and wet mixing. After the wet mixing is completed, the paste needs to be placed in the cooling machine for cooling. The traditional kneading equipment and process have the following defects: First, the working envir...

AI Technical Summary

Problems solved by technology

The traditional kneading equipment and process have the following defects: First, the working environment is poor. When the binder is heated, the light components in the binder will partly volatilize, and the components such as S and N contained in it will cause harm to the environment; However, due to the existence of fine particles during dry mixing, dust is easily generated, resulting in deterioration of the operating environment

Secondly, due to the temperature difference of the material in the kneading pot, the paste is likely to agglomerate, which in turn causes the phenomenon of "simmering pot", resulting in waste products and affecting the continuity of production

Again, the traditional process requires a large investment in equipment

Fourth, the paste formed after kneading is in the form of a spherical mixture with a size of 5 to 50 mm. There are uneven distribution of materials between the spherical mixture and inside the spherical mixture. This uneven phenomenon It is more serious in the production of fine-structured products, which seriously affects the final quality of the product. Therefore, when producing fine-structured carbon products, repeated rolling is required after the kneading process is completed, which prolongs the production cycle and increases production costs.

When this kind of kneading pot is kneading, the air pressure is applied to the inside of the pot through the pressure port to increase the pressure inside the pot to increase the wetting ability of the asphalt, thereby improving the kneading effect, but if the applied pressure is small, the kneading The effect is not improved obviously, and if the applied pressure is high, there are special requirements for the material and airtightness of the kneading pot, so its practicability is not strong
