Problems solved by technology

[0015] In fact, however, the poor overall positioning of the heating element and the insulating plate with respect to the spherical flask leads to unsatisfactory distillation characteristics obtained
[0016] Moreover, in the distillation equipment currently available on the market, the correct positioning of the spherical distillation flask cannot be ensured only empirically by placing the spherical distillation flask on an insulating plate closing the heating wall

Embodiment Construction

[0043] Such as figure 1 As shown, the device for heating a spherical distillation flask according to the present invention includes: a frame 1 on which a heating wall 2 is installed, and the heating wall 2 includes a heating component 3 .

[0044] The heating wall 2 is closed at its upper part by an insulating plate 4 provided with a central opening 5 for the bottom of said spherical distillation flask 6 .

[0045] The heating wall 2 is vertically movable between its two positions relative to the frame 1 of the distillation apparatus: i.e. figure 1 The high position (or operating position) shown in, in this position, insulation plate 4 keeps supporting this spherical distillation flask 6; And, figure 2 The low position (or stop position) shown in .

[0046] In order to facilitate the movement between the above two positions, the heating wall 2 is provided with a transfer column 7 at its lower part, which cooperates with the guide device 8 connected to the equipment frame 1,...

Abstract

The invention discloses a device for heating a spherical distilling flask, comprising: a frame, a heating wall for displacing the spherical distilling flask, an insulating board, and a control and regulation device, and further comprising: a spring carriage which vertically moves along the frame and is connected with the heating wall by a spring including fixing force to drive the heating wall to vertically move to an operating position or a ceasing position; a control device for controlling the spring carriage to vertically move along the frame; a stopping device which is mounted on the frame elastically and located at a connecting position, the heating wall is restricted at the operating position; when located at a separating position, the heating wall resets to the ceasing position.

Description

technical field [0001] The invention relates to a test device, in particular to a device for heating a spherical distillation flask. Background technique [0002] It is understood that the distillation characteristics of petroleum products are: the performance of petroleum products and the danger to users. The determination of the above-mentioned characteristics of petroleum products is especially important in the case of hydrocarbon fuels used in the automotive or aviation industries where safety issues are of utmost importance. These characteristics, especially those shown in graphs or curves, represent the percentage of vaporization of the sample with temperature during distillation, or also residues and losses. [0003] An expert in the industry can infer the characteristics to judge whether a given petroleum product can be used completely safely and achieve the properties sought under the given circumstances. [0004] In the above cases, experts in the field can set v...
