Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heating devices, in particular to an electromagnetic heating device for an oil storage barrel. BACKGROUND

[0002] In the process of industrial production of oil storage and use, the oil storage barrel bears the storage function of viscous oil such as diesel oil, lubricating oil and heavy oil. The viscosity of such oil is the key to its use. The viscosity increases sharply at low temperature, which will cause the oil flow to be blocked, and cannot meet the needs of equipment lubrication, fuel delivery and other needs, so the oil in the barrel must be heated by a heating device to reduce the viscosity.

[0003] Based on the above, it is found that the following problems exist: the heat in the existing electromagnetic heating device for the oil storage barrel is mainly transferred to the oil through electromagnetic induction heating of the barrel wall. However, the cohesive force between the molecules of viscous oil is strong, and the flow resistance is large. At the initial stage of heating, the oil near the barrel wall is heated and the density is reduced, which should form natural convection upward, but the high viscosity will offset the effect of buoyancy, and the convection movement is weak or even stagnant. The heat can only be transferred to the inside through the heat conduction of molecular collision, and the thermal conductivity of viscous oil is very low, resulting in very slow heat transfer in the device.

[0004] Therefore, in view of the above problems, the existing structure and defects are improved, and an electromagnetic heating device for an oil storage barrel is provided, so as to achieve the purpose of having more practical value. SUMMARY

[0012] Further, a high-temperature-resistant motor is fixedly installed at the top end of the base, and the output end of the high-temperature-resistant motor is in transmission connection with the heating core.

[0013] The beneficial effect of the above further scheme is that the high-temperature-resistant motor drives the heating core to drive the spiral fins to rotate, strengthens the turbulent effect of the oil, destroys the laminar flow form, reduces the adhesion and scaling of the oil, and at the same time speeds up the heat transfer, thereby further improving the heating efficiency.

[0014] Further, a connecting seat is fixedly installed at the bottom end of the base, the bottom end of the connecting seat is connected with the other side of the upper end surface of the base frame, and a heat dissipation grille is formed on the outer side of the base.

[0015] The beneficial effect of the above further scheme is that the connecting seat realizes stable connection of the heating mechanism and the base frame, and ensures the stability of the overall structure of the device; and the heat dissipation grille ventilates and dissipates heat for the high-temperature-resistant motor inside the base, avoids overheating and damage of the motor, and prolongs the service life of the equipment.

[0016] Further, a heat preservation layer is bonded to the inner side wall of the heating sleeve, the heat preservation layer is made of polyurethane material, and a plurality of temperature sensors are sequentially embedded and installed on the inner side wall of the heating chamber from top to bottom.

[0017] The beneficial effect of the above further scheme is that the heat preservation layer made of polyurethane material reduces heat loss in the heating chamber, saving energy consumption; and the plurality of temperature sensors monitor the temperature of the oil at different heights in real time from top to bottom, which is convenient for accurately regulating and controlling the heating process and avoiding excessively high temperature or uneven heating of the oil.
