[0002] Heated oil storage tanks are widely used in industrial and commercial applications. Tank heating methods include steam heating, electric heating, and hot oil heating. Electric heating primarily involves installing electric heating rods inside the tank or installing electric heating tapes outside the tank. The heating rods are inserted directly into the oil, converting electrical energy into thermal energy; the heating tapes are wrapped around the outside of the tank, heating the oil through heat conduction. Electric heating offers precise temperature control and ease of operation, but relatively high operating costs. It's suitable for smaller tanks or applications requiring high temperature control.

[0003] Hot oil heating: Circulates external, high-temperature thermal oil through heating coils inside or outside the tank, transferring heat to the oil. This method is common in some large oil storage and processing systems and can provide a stable, high-temperature heat source.

[0004] However, the existing hot oil heating method is relatively simple, and cannot adjust the excess space in the oil tank and the gas pressure in the pipe caused by the loss of oil, and requires frequent manual replenishment of new heat transfer oil. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable thermal oil tank, which can flexibly control the flow effect of the thermal oil and discharge the gas in time; so as to solve the technical problems raised in the above background technology.

[0013] As a further technical solution of the present invention, the pump group includes two pumps, and the liquid inlet end of each pump is equipped with a filter and an oil inlet valve, wherein the oil inlet valve is also connected to the oil collecting pipe;

[0014] The liquid outlet end of the pump is equipped with an oil outlet valve, and the oil outlet valve is also connected to the oil return pipe.

[0015] As a further technical solution of the present invention, the pump is electrically connected to the controller; a solenoid valve is serially connected to the oil supply pipe, and the solenoid valve is electrically connected to the controller.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this utility model, when the oil inlet pipe transports the thermal oil, some air will be generated inside due to the loss of thermal oil.

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0027] Please refer to Figure 1-4 , in the embodiments of the utility model, an adjustable heat conducting oil tank comprises an electric heater 1, one side of the electric heater 1 is provided with a pump group 2; the pump group 2 is connected with a heating tank 3 through an oil extraction pipe 9; the other end of the heating tank 3 is connected with the electric heater 1 through an oil inlet pipe 10; the oil extraction pipe 9 is connected with an oil supplement pipe 8 through a tee pipe, and the oil supplement pipe 8 is connected at the bottom of a heat conducting oil tank 5; the oil inlet pipe 10 is connected with an exhaust pipe 11 through a tee pipe, and the exhaust pipe 11 extends into the heat conducting oil tank 5.

[0028] More specifically, the heating tank 3 has a sandwich layer for containing heat conducting oil and heating the tank body; and the sandwich layer is connected with the oil extraction pipe 9 and the oil inlet pipe 10.

[0029] By adopting the above technical scheme, when in use, the electric heater 1 is used to heat the heat conducting oil, which is then delivered into the sandwich layer of the heating tank 3 through the oil inlet pipe 10 to heat the heating tank 3, so as to heat the materials in the tank; then the heat conducting oil is extracted by the pump group 2 through the oil extraction pipe 9 and then returns to the electric heater 1 for cyclic heating, so as to ensure the heating effect of the heat conducting oil on the heating tank 3.

[0030] When the oil inlet pipe 10 transports the heat conducting oil, some air will be generated inside due to the loss of the heat conducting oil, and the air will be discharged through the air outlet pipe 11 and then enter the heat conducting oil tank 5. Since the discharged gas has a certain temperature, the heat conducting oil can be preheated after being discharged into the heat conducting oil tank 5, and the heating time of the heat conducting oil can be reduced when the heat conducting oil is replenished subsequently, thereby achieving the function of energy saving and consumption reduction.

[0031] In the embodiment, the heat conducting oil tank 5 is fixed on the top of the rack body 4, and a guardrail 6 is further arranged on the top of the rack body 4; and a ladder 7 is further fixed on the outer side of the rack body 4.

[0032] The ladder 7 facilitates the climbing of the staff and the maintenance and maintenance of the heat conducting oil tank 5, and also facilitates the addition of the heat conducting oil into the heat conducting oil tank 5.

[0033] In the embodiment, the top of the heat conducting oil tank 5 is provided with a pressure relief valve and a safety valve.

[0034] By adopting the above technical scheme, the pressure relief valve and the safety valve can balance the pressure of the heat conducting oil tank 5, and ensure the safe use of the heat conducting oil tank 5.

[0035] In the embodiment, the pump set 2 includes two pumps 24, and a filter 22 and an oil inlet valve 23 are arranged on the liquid inlet end of each pump 24, wherein the oil inlet valve 23 is further connected with the oil collecting pipe 21.

[0036] The liquid outlet end of the pump 24 is provided with an oil outlet valve 25, and the oil outlet valve 25 is further connected with the oil return pipe 26.

[0037] By adopting the above technical scheme, whether the pump set 2 works as a single pump or a double pump is realized by the opening and closing of the oil outlet valve 25 and the oil inlet valve 23; in the initial stage, the double pump working can quickly realize the flow of the heat conducting oil and speed up the heating speed of the heating tank 3; in the constant temperature rising state, the single pump working realizes the energy saving effect under the condition of ensuring the normal circulation of the heat conducting oil.

[0038] In the embodiment, the pump 24 is electrically connected with the controller 12; and an electromagnetic valve is connected in series on the oil supplement pipe 8, and the electromagnetic valve is electrically connected with the controller 12.

[0039] When the recyclable heat conducting oil is reduced due to loss, the controller 12 controls the electromagnetic valve to open, and the heat conducting oil in the heat conducting oil tank 5 passes through the oil supplement pipe 8 and enters the oil suction pipe 9, thereby realizing the addition of the heat conducting oil and ensuring the sufficiency of the heat conducting oil.

[0040] The working principle of the present utility model is: when in use, the electric heater 1 is used to heat the heat-conducting oil, which is then transported to the interlayer of the heating tank 3 through the oil inlet pipe 10 to heat the heating tank 3, so as to heat the material in the tank; then the heat-conducting oil is extracted by the pump group 2 through the oil extraction pipe 9, and then flows back to the electric heater 1 for circulation heating, thereby ensuring the heating effect of the heat-conducting oil on the heating tank 3.

[0041] When the oil inlet pipe 10 transports the thermal oil, some air will be generated inside due to the loss of the thermal oil. The air will be discharged through the exhaust pipe 11 and then enter the thermal oil tank 5. Since the exhausted gas has a certain temperature, it can preheat the thermal oil after being discharged into the thermal oil tank 5. When the thermal oil is subsequently replenished, the heating time of the thermal oil can be reduced, thereby achieving the function of energy saving and consumption reduction.

[0042] Whether the pump group 2 is operating as a single pump or as a dual pump is determined by opening and closing the oil outlet valve 25 and the oil inlet valve 23; in the initial stage, the dual pump operation can quickly realize the flow of the thermal oil and speed up the heating speed of the heating tank 3; in the constant temperature rising state, the single pump works to achieve energy saving while ensuring the normal circulation of the thermal oil; when the circulatory thermal oil is reduced due to loss, the controller 12 controls the solenoid valve to open, and the thermal oil in the thermal oil tank 5 is connected to the oil extraction pipe 9 through the oil replenishment pipe 8, thereby realizing the addition of thermal oil to ensure the sufficiency of the thermal oil.
