Combined explosion-proof electric heater

Abstract

The invention provides a combined explosion-proof electric heater. The combined explosion-proof electric heater comprises a first heater, a second heater, a first connecting pipe, a second connecting pipe and a third connecting pipe, wherein the first heater comprises a first explosion-proof terminal box, a first container body, and a first container cover, wherein a first heating cavity of the first heater is divided into a first chamber, a second chamber and a third chamber by a first partition plate and a second partition plate; the second heater comprises a second explosion-proof terminal box, a second container body, and a second container cover; a second heating cavity of the second heater is divided into a fourth chamber, a fifth chamber and a sixth chamber by a third partition plate and a fourth partition plate; two ends of the first connecting pipe separately communicate with the first chamber and the fourth chamber; two ends of the second connecting pipe separately communicate with the second chamber and the fifth chamber; and two ends of the third connecting pipe separately communicate with the third chamber and the sixth chamber. According to the combined explosion-proof electric heater disclosed by the invention, the flowing stroke of fluid is extended, and the heating time of the fluid is prolonged, so that the fluid can be sufficiently heated, and the heating effect is improved.

Description

technical field [0001] The invention relates to the technical field of electric heaters, in particular to a combined explosion-proof electric heater. Background technique [0002] The explosion-proof electric heater includes a container shell, an explosion-proof chamber, a plurality of electric heating pipes, and a plurality of transition sleeves, and the container shell is provided with an inlet and an outlet; the existing explosion-proof electric heaters have mostly one container shell The straight cylindrical tube body and the electric heating tube are arranged in the container shell, so that the stroke of the fluid in the container shell is short, and the fluid cannot be fully heated, resulting in an unsatisfactory heating effect. SUMMARY OF THE INVENTION [0003] Based on the technical problems existing in the background art, the present invention proposes a combined explosion-proof electric heater. [0004] A combined explosion-proof electric heater proposed by the ...
