The utility model relates to the technical field of constant temperature liquid tanks, in particular to a constant temperature oil tank with good heat preservation effect for constant temperature heating. As the name suggests, a thermostatic bath is a bath that provides constant temperature. It can be divided into constant temperature air tank and constant temperature liquid tank, which is a constant temperature liquid. The tank is widely used in aviation, aerospace, shipbuilding, information, electronics and other fields. Constant or alternating damp heat test and humidity gradient or sudden change test for instruments, electrical products, materials, components and equipment to evaluate the behavior and performance of samples under given environmental conditions. The temperature stability of the constant temperature oil tank is an important criterion for considering the quality of the constant temperature oil tank. A constant temperature environment with stable and small fluctuations is an indispensable condition for the use of the constant temperature oil tank, and the external ambient temperature has a great influence on the temperature stability of the constant temperature oil tank. However, the existing constant temperature fuel tank generally has a heating device at the bottom of the fuel tank, and the heating area is small. In order to ensure the stability of the temperature in the fuel tank, although the heating device is always in working state, the temperature at the bottom of the fuel tank cannot be transferred upwards in time after heating, and the temperature stability in the constant temperature fuel tank often fails to meet the requirements. At the same time, the existing constant temperature fuel tank has poor thermal insulation effect, and heat is easily transferred to the external environment, resulting in heat dissipation. How to solve the above technical problems is the direction of those skilled in the art.

The purpose of the utility model is to provide a constant temperature oil tank with good thermal insulation effect, so as to solve the technical problems of uneven heating and poor thermal insulation effect of the existing constant temperature oil tank. The utility model specifically adopts the following technical solutions to achieve the above purpose: a constant temperature oil tank with good thermal insulation effect, comprising a box body, a constant temperature chamber arranged in the box body, and an oil storage tank for filling oil into the constant temperature chamber; There are two lifting mechanisms symmetrically arranged under the constant temperature chamber; the bottom of the constant temperature chamber is provided with a composite heating mechanism and a magnetic stirrer; the outer bottom of the constant temperature chamber is fixed with a mechanism for driving the rotation of the magnetic stirrer. There is a vertical guide mechanism in the constant temperature oil tank box to prevent the deviation of the constant temperature chamber. The vertical guide mechanism includes vertical guide rods symmetrically arranged on both sides of the constant temperature chamber. Each vertical guide rod is provided with a guide ring. There is a press ring, and two sides of the press ring are provided with connecting blocks which are detachably connected with the corresponding guide rings. The lifting mechanism includes two steps. The lower step of the step table is provided with a supporting plate a and a supporting plate b. A rotating shaft is arranged between the top of the supporting plate a and the supporting plate b. The rotating shaft is provided with an eccentric wheel. The top of the thermostatic chamber is in contact with the bottom of the thermostatic chamber; the steps on the step table are provided with a drive motor that drives the rotating shaft to rotate. The compound heating mechanism of the constant temperature oil tank includes a plurality of heating pipe assemblies evenly distributed at the bottom of the constant temperature chamber, each heating pipe assembly is provided with partitions on both sides, and the heating pipe assembly includes a straight pipe section and a curved pipe section connected at one end, and the straight pipe section and the curved pipe section are connected. The other end of the pipe section extends out of the thermostatic chamber and is connected to the power cord connector. The outside of the constant temperature oil tank body is provided with an oil inlet and a transparent oil level pipe which are respectively connected with the top and bottom of the oil storage tank. The tank body is also provided with a refueling pipeline. One end of the refueling pipeline is connected to the inner bottom of the oil storage tank through a hose, and the other One end is above the constant temperature chamber.

The utility model has the following beneficial effects:

1. The utility model has a simple structure. During the heating process of the constant temperature oil tank, when the magnetic drive mechanism rotates, the magnetic stirrer can be driven to rotate at the bottom of the constant temperature chamber. This stirring method has a simple structure and does not require a complicated stirring mechanism, so that the water heating effect in the constant temperature room is better, and the temperature in the constant temperature room is more uniform; Prevent heat loss. The setting of the oil storage tank of the constant temperature oil tank can choose whether to refuel according to the amount of oil in the constant temperature room.

2. There is a lifting mechanism in the box below the constant temperature chamber of the constant temperature oil tank, which drives the constant temperature chamber to move up and down. When working, adjust the lifting mechanism to adjust the constant temperature room to a suitable height, which is convenient for workers of different heights to operate, and then turn on the heating mechanism to heat the oil in the constant temperature room to the required temperature.

3. The constant temperature oil tank is provided with a vertical guide mechanism to prevent the incubator from deviating. This structure can prevent the incubator from deviating or generating lateral vibration during the lifting process, thereby affecting the use of the equipment.

4. The compound heating mechanism of the constant temperature oil tank includes a plurality of heating pipe assemblies evenly distributed at the bottom of the constant temperature chamber. There are partitions on both sides of each heating pipe assembly. The heating pipe assembly includes straight pipe sections and curved pipe sections. It can effectively increase the area of ​​the bottom heat source, and the heating effect is better.

5. There is a transparent oil level pipe connected to the bottom of the oil storage tank on the outside of the constant temperature oil tank. Since the oil level in the oil storage tank cannot be seen, the oil level in the oil storage tank can be known through the transparent oil level tube.

6. The present invention has the advantages of simple structure, convenient installation and installation, low cost and good stability.
