Electric heating tube insulation device

Abstract

The invention relates to the technical field of electric heating, in particular to an electric heating tube insulating device. The electric heating tube insulating device comprises an electric heating tube body, wherein the electric heating tube body comprises a tube body 1 of an electric heating tube; an electric heating wire 51 is arranged in the tube body 1 of the electric heating tube and is connected with a leading rod 5; magnesium oxide powder 11 is injected between the electric heating wire 51 and the tube body 1; a clamping sleeve 2 is arranged on the outer side of one end of the tube body 1 of the electric heating tube; the tube body 1 of the electric heating tube is fixedly connected to a tube plate 10 through the clamping sleeve 2; a sealing ring 3 is arranged between the end surface of the clamping sleeve 2 and the tube plate 10; an insulating plug 4 is arranged at one end, far away from the sealing ring 3, of the clamping sleeve 2; the leading rod 5 of the tube body 1 of the electric heating tube penetrates through the insulating plug 4; the clamping sleeve 2 and the insulating plug 4 are sealed; the insulating plug 4 and the leading rod 5 are sealed. The electric heating tube insulating device is used for various types of electric heating tubes; the insulating effect is better; moreover, the service life of an electric heater can be prolonged.

Description

technical field [0001] The invention relates to the technical field of electric heating, in particular to an insulating device for electric heating pipes. Background technique [0002] During the use of traditional electric heaters, the proportion of electric heaters damaged or unusable due to the reduction of the insulation resistance of electric heating tubes is very high. In addition, the most commonly used magnesium oxide powder insulation material for electric heaters is very easy to absorb moisture and lose its insulating ability. Therefore, the electric heater is often damaged due to insulation problems before it is used, which greatly affects the service life of the electric heater. There are many insulation and sealing methods to introduce electric heating pipes at home and abroad, but they have not been thoroughly solved and improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric heating ...

[0002] During the use of traditional electric heaters, the proportion of electric heaters damaged or unusable due to the reduction of the insulation resistance of electric heating tubes is very high

In addition, the most commonly used magnesia powder insulation material for electric heaters is very easy to absorb moisture and lose its insulating ability. Therefore, the electric heater is often damaged due to insulation problems before it is used, which greatly affects the service life of the electric heater.

There are many insulation and sealing methods for electric heating tubes at home and abroad, but they have not been completely solved and improved.
