Problems solved by technology

[0002] Existing oil tanks usually install heating pipes on the shell when heating the oil, but this heating method has a small contact area with the oil, so the heat conduction efficiency is not high. In addition, the heat loss is large, resulting in energy waste

Abstract

The invention discloses an oil tank heating device. The oil tank heating device comprises an oil tank body, and the oil tank body comprises an inner shell, a middle layer shell and an outer shell layer. A heating gap is formed between the inner shell and the middle layer shell. A reflux gap is formed between the middle layer shell and the outer shell layer. The right end of the heating gap communicates with a liquid inlet pipe, the reflux gap communicates with a reflux pipe, and the reflux pipe is arranged outside the liquid inlet pipe in a sleeving mode. The reflux pipe communicates with theliquid inlet pipe through a circulating pipe. A circulating pump and a heater are mounted on the circulating pipe. The left end of the reflux gap and the left end of the heating gap communicate with each other through a communicating hole. According to the oil tank heating device, the reflux gap is used for preserving the heat of the heating gap, due to the fact that the temperature of the refluxgap is lower, heat loss is reduced, and heat loss is effectively reduced; and moreover, oil in the oil tank can flow through overall heating of the gap layer and ultrasonic vibration, and the heat transfer efficiency is improved.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to an oil tank heating device. Background technique [0002] Existing oil tanks usually install heating pipes on the shell when heating the oil, but this heating method has a small contact area with the oil, so the heat conduction efficiency is not high. In addition, the heat loss is large, resulting in energy waste. Contents of the invention [0003] In order to solve the above problems, the present invention provides an oil tank heating device. The present invention uses the backflow gap to insulate the heating gap. Because the backflow gap temperature is lower, the heat loss is reduced, thereby effectively reducing the heat loss, and the gap layer is heated as a whole, and the oil in the oil tank is made to flow through ultrasonic vibration. Thereby increasing the heat transfer efficiency. [0004] For reaching above-mentioned technical effect, technical scheme of the present inventi...
