Problems solved by technology

The radiant tube of the electric radiant tube in the prior art is a straight tube with equal wall thickness. The structure of the electric radiant tube with this structure is simple and easy to manufacture. However, when heating, since the radiant tube is a straight tube with equal wall thickness, the heater The heat is transferred to the entire radiant tube, not only the heating section of the radiant tube is heated by external radiation, but also the other parts of the radiant tube except the heating section are also heated by external radiation, resulting in a lot of energy waste and low heating efficiency

Abstract

The invention discloses an efficient and energy-saving type electric radiant tube heater which comprises a straight tubular radiant tube, and a heater and a flange which are arranged in the radiant tube. The radiant tube is provided with at least one annular partition slot on the inner wall between the end portion of the heater and the flange. The further improvement is that a heat-resisting nonmetallic material is arranged in the partition slot. According to the invention, by blocking the heat transfer on the radiant tube, the heating efficiency can be significantly improved, and the energy consumption is significantly reduced.

Description

technical field [0001] The invention relates to an electric heater, in particular to an electric radiant tube electric heater for electric heating furnaces. Background technique [0002] The electric radiant tube heater is an important part of the electric heating furnace. It generally includes a radiant tube and a heater installed in the radiant tube. The part corresponding to the axial direction of the radiant tube and the heater in the tube is the heating section. Play an effective radiant heating effect. The radiant tube of the electric radiant tube in the prior art is a straight tube with equal wall thickness. The structure of the electric radiant tube with this structure is simple and easy to manufacture. However, when heating, since the radiant tube is a straight tube with equal wall thickness, the heater The heat is transferred to the whole radiant tube, not only the heating section of the radiant tube is heated by external radiation, but also the other parts of the...
