The patented technology of the present invention discloses an oil storage tank having a heating device. It comprises a can body and an electric heater interface arranged side by side on the circumferential surface of the can body, the electric heater being inserted radially into the can body through the electric heater interface and extending into the bottom of the can body. The distance between the two electric heaters to the end faces of the cans is equal. The tank body is also provided with a circulation pipeline. The inlet end of the circulation pipeline is connected with the middle end face of one side of the tank body. The outlet end of the circulation pipeline extends radially from the bottom of the tank body to the middle part of the tank body. The outlet side of the circulation pipeline is provided with a temperature measuring mouth, a temperature measuring device is arranged in the temperature measuring mouth, and an exhaust port is arranged on the side of the temperature measuring mouth. After adopting the above structure, the oil in the tank is heated uniformly, the product performance is ensured, the heating time is greatly shortened, and the efficiency is improved. In addition, the temperature measuring port is arranged between the electric heating pipes, and the temperature measurement accuracy is greatly improved under the condition of heating uniformity, and the structural design is reasonable and the cost is low.

[Summary of technical implementation steps]
The patented technology relates to an oil storage tank, and more particularly to an oil storage tank having a heating device.

Technology Introduction
Oil storage tanks are a common oil storage facility. Its performance and use status directly affect economic benefits. Under the condition of lower temperature, the oil in the tank is easy to condensate when it is cooled, whether it needs to be taken out or transported. It usually needs to be heated to increase the fluidity so that it can be taken out or convenient for transportation. In the prior art, the hot water heating method has been used. In the prior art, on the one hand, the heating time is long, the efficiency is low, and in addition, the uniformity of heating is poor, so that the product performance is deteriorated. On the other hand, installing a boiler has high cost and low utilization rate, resulting in waste of cost. he temperature inside the can is not uniform and it is difficult to obtain an accurate temperature.



Technical realization ideas
The technical problem to be solved by the patented technology is to provide an oil storage tank having a heating device with high heating speed, good uniformity, high efficiency and low cost. In order to solve the above technical problems. An oil storage tank having a heating device of the patented technology. The utility model comprises two electric heater interfaces arranged side by side on the tank body and the circumferential surface for plugging in the electric heater. The electric heater is radially inserted into the tank body through the electric heater interface and extends to the bottom of the tank body. The distance between the two electric heaters to the end faces of the cans is equal. The tank body is further provided with a circulation line, and the inlet end of the circulation line is connected to the middle of the end surface of one side of the tank body. The outlet end of the circulation line projects radially from the bottom of the can body to the middle of the can body. A temperature measuring port is arranged on one side of the outlet end of the circulation pipeline, and a temperature measuring device extending into the tank body is arranged in the temperature measuring port, and an exhaust port is arranged on one side of the temperature measuring port. One side of the exhaust port is provided with a safety valve. The upper end surface of the can body is provided with an upper level gauge interface at the upper middle portion and a lower level gauge interface at the middle portion. The tank body is further provided with a nitrogen filling protection port located outside one of the heating devices. An upper portion of the end surface where the inlet end is located is provided with an overflow port. The bottom edge position of the tank body is provided with a sewage outlet. After adopting the above structure, the electric heater is electrically operated by means of an electric heater interface arranged side by side on the circumferential surface of the tank body.
