A large-capacity constant temperature box for petroleum sample detection

Abstract

The invention provides a high-capacity thermotank for petroleum sample detection. The high-capacity thermotank includes an outer box with a door, an inner box in the outer box and a constant temperature heating device. The inner box is internally equipped with at least one vertical rotating column, and the periphery of the rotating column is surrounded by clamping devices, the high-capacity thermotank also includes a circuit board and a motor, the circuit board and the motor are both mounted between the outer box and the inner box to drive the rotating column to rotate, the plurality of clamping devices are clamping rings, the surfaces of the clamping rings are provided with subareas, a fixed ring is disposed above each placement area, and the fixed rings are fixed on the surface of the rotating column. The rotating column's surface areas equipped with the fixed rings are all provided with grooves, a horizontal rotating shaft is disposed at the bottom of each groove, and two side walls of the groove in which the rotating shaft is fixedly arranged are both equipped with a slideway sliding up and down, and each slideway includes a stop device.

Description

technical field [0001] The invention relates to the technical field of testing instruments, in particular to a large-capacity constant temperature box for testing petroleum samples. Background technique [0002] Most of the experimental ones are electric thermostats, equipped with electric heaters and temperature regulators, which are boxes or cabinets with insulating materials on the outer walls. Samples or materials stored at constant temperature have strict requirements on temperature, too high or too low temperature will lead to obvious experimental errors. The commonly used incubator has a simple structure. Its structure is that the box has built-in heating elements and a temperature controller, and the heating elements mostly use low-cost heating tubes. The heating tubes increase the surrounding temperature through self-heating. Raise to the equilibrium temperature, which makes the rising temperature above the heat pipe slightly higher, while the temperature inside th...

Problems solved by technology

[0005] In order to overcome the problems existing in the prior art that the constant temperature box accommodates less parts to be tested, the manufacturing cost is high, and the box body is large in volume, the effect of turbulence is not very ideal, and thus the effect of reducing the temperature difference is very limited, the present invention provides A large-capacity constant temperature box for petroleum sample detection
