Technical Field

[0001] The utility model relates to the technical field of chemical substance preparation, in particular to a tubular heater. Background Art

[0002] Chemical substances refer to substances composed of different atoms or molecules, which change through chemical reactions, including colorless transparent liquids such as p-dichlorobenzene, o-dichlorobenzyl, and m-dichlorobenzene. When preparing colorless transparent liquids such as p-dichlorobenzene, o-dichlorobenzyl, and m-dichlorobenzene, it is necessary to use equipment such as reactors, distillation towers, and crystallizers. In the reactor, the tubular heater is one of the important components. The tubular heater can transfer heat energy to the reactor and provide the required energy for the chemical reaction. It can effectively increase the reaction speed and efficiency and promote the progress of the chemical reaction.

[0003] At present, when the tubular heater is used, there is a lack of a structure that facilitates its positioning. The tubular heater is prone to loosening during operation, resulting in poor stability of the tubular heater. For this reason, we propose a tubular heater. Utility Model Content

[0008] The personnel connect the end positioning head to the carbon fiber electric heating tube, and then connect the end positioning head to the inner wall of the cavity with a small flange, which can further enhance the stability of the carbon fiber electric heating tube.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] In order to improve the stability of the tubular heater, such as Figure 1-4 As shown, a tubular heater described in the utility model comprises a reaction kettle 1, a carbon fiber electric heating tube 4 and a positioning seat 7, the upper end of one side of the reaction kettle 1 is connected with a power line 14, the other end of the carbon fiber electric heating tube 4 is fixed with a terminal 9, and the current output end of the power line 14 is electrically connected to the current input end of the carbon fiber electric heating tube 4 through the terminal 9;

Positioning plates 8 are provided at both ends of one side of the positioning seat 7, and mounting holes 15 are provided inside the positioning plates 8. One end of the carbon fiber electric heating tube 4 is connected to an end positioning head 10, and a small flange 11 is fixed to one side of the end positioning head 10.

[0029] The personnel connect the end positioning head 10 to the carbon fiber electric heating tube 4, and then connect the end positioning head 10 to the inner wall of the cavity 5 through the small flange 11, which can further enhance the stability of the carbon fiber electric heating tube 4.

[0032] For example, Figure 1 As shown, a cavity 5 is provided inside the reactor 1 , and a heat preservation plate 6 is embedded on the outside of the cavity 5 inside the reactor 1 .

[0033] When in use, the cavity 5 is convenient for personnel to install the carbon fiber electric heating tube 4 inside the reactor 1 , and the insulation board 6 is made of asbestos material with poor thermal conductivity, which can prevent the heat dissipation inside the reactor 1 .
