Ceramic electric heating carrier and preparing method thereof

Abstract

A ceramic electric heating carrier comprises a heating carrier body, a heating wire is arranged inside the heating carrier body, the two ends of the heating wire are provided with heating wire connectors, the heating carrier body is made of high-temperature ceramic materials, and the heating carrier body is provided with installing holes and heat dissipating holes. A preparing method comprises the steps of preparation of raw materials and gel-casting formation. According to the step of preparation of the raw materials, the formula raw materials are added to a ball grinding machine to be mixed and levigated for 12-14 hours, the raw materials are roasted and synthesized, levigation is carried out for 8-10 hours, and 0.8-1.5% of chitosan is added to the formula materials to be stirred evenly to be a standby after the formula materials are screened through a 160-mesh vibration screen. According to the forming and casting process comprising raw material slurrying and matching, a product mold is placed on a vibration platform to be vibrated for the first time, namely, the mold is taken down from the platform to be paved with the heating wire, the mold is placed on the vibration platform to be poured with a needed amount of slurry, and then the mold is taken down from the platform to stand to be solidified. The ceramic electric heating carrier has the advantages that the carrier body cannot be exploded or oxidized and is even and stable when used for heating in the high-temperature environment, heat transmission is fast, the energy-saving effect is obvious, the mold does not deform, the specification standard is uniform, assembling is convenient, the technology is simple, production efficiency is high, and production cost is greatly reduced.

Description

technical field [0001] The invention relates to a ceramic electric heating heating carrier and a preparation method thereof. Background technique [0002] The traditional structure of this product is that the mica insulating medium and the resistance wire are supported by the lining and the heating sheet is made of a metal material outside. Its structure is complex, unreasonable, high in cost and short in service life. The resistance wire and the insulating ceramic slurry are injected and connected with the metal garden pipe to form a single body. The external matching metal shell is easy to rust, and the indirect heat transfer heat efficiency is poor and the energy consumption is high. [0003] The TPC ceramic heater in the existing market is self-conducting and heating, the resistivity changes with temperature, the resistivity increases when the temperature rises, the current drops, and the heating rate changes. The Curie temperature of TPC ceramics is low, and the contro...

AI Technical Summary

Problems solved by technology

The curie temperature of TPC ceramics is low, and the control temperature is also low. Therefore, it is affected by the surrounding close environment, which is not conducive to continuous heat generation. It can only be used as a part of the air conditioner to heat the working medium, and cannot be made into an independent heater.
