Problems solved by technology

There are two existing dry material heating methods: one is to heat the dry material through a separate dry material heating device such as a dry material preheating screw, the system first heats the screw, and then conducts heat through the dry material preheating screw Feed the dry material, after the dry material reaches a certain temperature, it is transported to the kneading pot for dry mixing and wet mixing. This method needs to preheat the dry material first, which causes waste of energy, and the problem of dust and smoke is not well solved. The other is to directly transport the dry material to the kneading pot for dry mixing, and increase the temperature of the dry material by prolonging the dry mixing time, which requires that the kneading pot itself must have a heating function. The phenomenon that the reamer destroys the large particles in the dry material, thereby changing the original particle size formulation, and making the final performance of the product deviate from people's expectations
Both methods have inaccurate temperature control, resulting in differences in paste quality between different batches.

Abstract

The invention discloses a dry material heater, which consists of a top cap (5), a cavity (11), a feed opening (2), a discharge door (10), an electrode plate (7), a ventilating duct (1), a flue gas duct (4), an infrared thermometer (3) and the like. The dry material heater is characterized in that: the feed opening (2) is formed at the central position of the top cap (5); the infrared thermometer (3) is arranged beside the feed opening (2); the top cap (5) is connected with a cavity wall (6); the electrode plate (7) is fixed on the inner surface of the cavity wall (6); the discharge door (10) is arranged at the bottom of the cavity (11); and the ventilating duct (1) and the flue gas duct (4) are communicated with the cavity (11) through the top cap (5). Through the dry material heater, theheating temperature of a dry material can be accurately controlled, the energy consumption is reduced, the production efficiency is improved, and dust and flue gas pollution is reduced.

Description

technical field [0001] The invention relates to a dry material heater, in particular to a dry material heater used in the field of traditional carbon product production, and the invention can also be applied to applicable occasions in other industries. technical background [0002] Traditional carbon products such as graphite electrodes and prebaked anodes generally use coke as aggregate and coal tar pitch as binder, and some products also add a small amount of additives such as iron oxide powder, etc., after kneading, pressing, roasting, impregnation, graphitization, etc. The production process finally forms the product. The kneading effect of coke and asphalt is one of the key factors affecting the final performance of the product. The main technical parameters of kneading include kneading temperature and kneading time. According to the types of products produced and the properties of the used asphalt, the kneading temperature is generally controlled at 140 Between ~180°C...
