Example Embodiment

[0032] Embodiment one:

[0033] According to the proportion of ceramic raw materials (clay) accounting for 90% of the weight of the mixture, conductive filler particles with a particle size of 5μ-10μ accounting for 10% of the weight of the mixture, the mixture is composed, and the traditional manufacturing methods such as mixing, ball milling, granulation, molding, sintering, and glazing are used. The outer surface is insulated, and the ceramic tube with conductive strips embedded in the middle is made by pottery technology.

Example Embodiment

[0034] Embodiment two:

[0035] The mixture is composed of clay accounting for 50% of the weight of the mixture and conductive filler particles with a particle size of 50μ accounting for 50% of the weight of the mixture. After a traditional sintering process, a ceramic tube with an insulating outer surface and a conductive strip embedded in the middle is prepared.

Example Embodiment

[0036] Embodiment three:

[0037] The mixture is composed of clay accounting for 75% of the weight of the mixture, and conductive filler particles with a particle size of 30μ accounting for 25% of the weight of the mixture. After a traditional sintering process, a ceramic tube with an insulating outer surface and a conductive strip embedded in the middle is prepared.

Abstract

Two or more electric heating electrodes are arranged orderly and in interval along axial line or in annular along cross section inside ceramic tube. Material of the ceramic tube is evenly mixed china clay and stuffing of current conducting fine particle. Preparing an insulated surface according to conventional method for manufacturing ceramic tube and embedding bus bar in advance or posting bus bar after makes electric heater unit. The electric heater unit could be solid rod shaped. The invention has advantages of good water resistance and insurability, high safety and high conversion efficiency of electric heating.

Description

technical field [0001] The invention relates to a conductive heating ceramic tube and a preparation method thereof. Background technique [0002] Most of the traditional water heating methods provide low-temperature heat by burning coal and gas. Because the chemical energy in the fuel is not fully utilized, there is a huge waste, and a large amount of CO is emitted during combustion 2 , SO 2 Harmful substances such as dust and dust not only cause environmental pollution, but also lead to ecological damage, such as: greenhouse effect, acid rain, etc. [0003] Electric heat source is a clean and direct energy source. With the development of nuclear energy and hydropower generation, extensive use of electric heating has great significance for saving coal and gas resources and protecting the environment. [0004] The existing electric heating methods mainly include wire heating electric heaters, air conditioners, electric heating films, cable floors, etc. Electric heaters wi...
