An air inlet pipe 21 and an air outlet pipe 22 are installed at the top of the heating oil storage tank 17, a one-way valve 23 is installed on the air inlet pipe 21, and a pressure valve 24 is installed on the air outlet pipe 22. For adjusting the pressure balance in the heating oil storage tank 17.
When the heating oil heating device is used, the heating oil is heated, then is pumped out through the liquid inlet pipe 14, is conveyed to the inner cavity 12 to heat materials, then flows to the outer cavity 13 through the communicating pipe 15, and then returns to the heating oil storage tank 17 to be heated again, and because the heating oil after the temperature reduction of the backflow is filled in the outer cavity 13, the heating oil in the inner cavity plays a heat preservation effect, so that the influence of the external temperature is effectively reduced.
