Problems solved by technology

[0002] At present, most of the straight rods in the prior art use large helical wires, and the center electrode wire needs to pass through the inside of the helix wire. The current structure has a small electrical gap, and long-term use will cause the helix wire and the center electrode wire to be disconnected. The tube wall of the electric heating tube bursts, which is very dangerous. In order to improve the work efficiency, improve the practicability of the electric heating tube, prolong the life of the heating tube, and reduce the risk, the invention proposes a single-head U-shaped tube with a detachable straight rod. Electric heating tube

Abstract

The invention discloses a straight rod detachable type electric heating pipe with a single-end U-shaped pipe, and belongs to the technical field of electric heating pipes. The electric heating pipe comprises a sealed bottom, the top is provided with a high-temperature porcelain head and two metal steel pipes which are different in lengths and are connected side by side, the top of the high-temperature porcelain head is further connected with a binding post, a U-shaped single-port magnesium oxide pipe is arranged inside the pipe body of each metal steel pipe, each U-shaped single-port magnesiumoxide pipe extends towards the bottom from the one-third position of the interior of the corresponding metal steel pipe, double-port magnesium oxide pipes matched with two ends of each U-shaped single-port magnesium oxide pipe are arranged at the two ends of each U-shaped single-port magnesium oxide pipe respectively, the U-shaped single-port magnesium oxide pipes are wrapped with the double-portmagnesium oxide pipes, and an electric resistance wire is paved inside each U-shaped single-port magnesium oxide pipe. According to the electric heating pipe designed in the invention, the heating efficiency is improved, the service life is prolonged, and the electric heating pipe is simple in structure and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of electric heating tubes, in particular to a single-headed U-shaped tube with a detachable straight rod electric heating tube. Background technique [0002] At present, most of the straight rods in the prior art use large helical wires, and the center electrode wire needs to pass through the inside of the helix wire. The current structure has a small electrical gap, and long-term use will cause the helix wire and the center electrode wire to be disconnected. The tube wall of the electric heating tube bursts, which is very dangerous. In order to improve the work efficiency, improve the practicability of the electric heating tube, prolong the life of the heating tube, and reduce the risk, the invention proposes a single-head U-shaped tube with a detachable straight rod. Electric heating tube. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a sing...
