Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting oil tanks, in particular to a heat-conducting oil tank. Background Art

[0002] The thermal oil tank is to directly heat the organic carrier (thermal oil) by inserting the electric heater directly, and then forcing the liquid phase to circulate through the high-temperature oil pump, and then transport the heated thermal oil to the heat-using equipment, and then return to the hot oil furnace for heating from the oil outlet of the heat-using equipment, forming a complete circulation heating system. The thermal oil heater uses a digital temperature controller to control the temperature, and has over-temperature alarm, low oil level alarm, and over-pressure alarm functions. It is an efficient and energy-saving heating equipment in the chemical, textile, printing and dyeing, food, plastic, film and other industries.

[0003] When the existing thermal oil tank is in use, the thermal oil in the tank is heated only by an electric heater. As a result, when the thermal oil is heated, the temperature of the oil near the heater is higher, while the temperature of the oil far from the heater is lower, causing uneven heating of the thermal oil. There is a problem where the temperature sensor shows that the temperature meets the standard, but the temperature of the thermal oil at other locations in the tank does not meet the standard, and the oil is drained, resulting in the problem of insufficient temperature of the heat-using equipment. In this regard, we have proposed a thermal oil tank to solve the above-mentioned problems. Utility Model Content
