Description

Vertical continuous mixing machine

Technical field

The present invention relates to a kneader, and more particularly to a vertical continuous kneader.

Background technique

In the narrow sense, the kneading process is divided into two sections. The front section is called dry mixing. That is, the coke granule aggregate and powder with a certain particle size composition are heated and mixed uniformly in the kneading pot; the latter section is called wet mixing, that is, adding liquid. Continued mixing after the binder, also known as kneading, is called kneading together. The kneading process requires the material to have a higher temperature to ensure sufficient penetration and penetration of the liquid binder to the aggregate and the powder, thereby improving the kneading quality. Therefore, depending on the requirements of the carbon product, the kneading temperature is usually between 175 and 210 °C. However, in order to ensure the quality of the product in the subsequent molding process, according to the different requirements of the carbon product, the temperature of the material needs to be rapidly lowered to 114 to 150 ° C before the material is transported to the molding equipment, so the kneading process in a broad sense should also be Includes the cool stage. At present, there are special equipments at each stage: dry mixing machines in the dry mixing stage, wet mixing machines in the wet mixing stage, and cooling machines in the cool stage. In the actual production, there has been a device for combining a dry mixer and a wet mixer, that is, a continuous kneader in a narrow sense, such as a double-layer preheating kneader described in the Chinese invention patent No. 101530755, "Light Metal" On page 37 of the first issue of 2007, Yuan Renchun's "Continuous Kneading Machine's Kneading Mechanism Research and Its Guidance for Production Maintenance" is published, and a Chinese invention patent with the publication number 102188920A is described as a continuous Kneading machine, but from the public content, the previous invention patent only involves the "mixing" and "pinching" stages, and does not involve the cooling stage of the material after kneading, not the continuous kneading machine in the true sense or in the broad sense; Not only are the continuous kneaders in a broad sense, but they are not vertical but horizontal kneaders.
