The utility model has the advantages of simple structure, high heat efficiency, and convenient installation and maintenance.

Description

A kind of electric heater unit that is used for reactor

The utility model relates to a kind of electric heater unit, a kind of electric heater unit that is used for reactor of more specifically saying so

Electric heating reacting kettle commonly used at present is that electrothermal tube is installed in the chuck of reactor, make the reactor heating by the conduction oil that charges in the heating jacket, because the heat transfer property of oil is limited, for improving rate of heat transfer, pot adopts stainless steel material to make usually in the reactor, so cost costliness and maintenance difficult.

The purpose of this utility model provides a kind of simple in structure, thermal efficiency height, and the electric heater unit in the reactor is directly inserted in installation, maintenance easily.

The purpose of this utility model is realized by following technical scheme.

The utility model is made up of electrothermal tube, sleeve pipe, outer tube, dividing plate and arm, it is characterized in that:

The electrothermal tube that has groove on a, the outer wall inserts in the middle of the sleeve pipe, and the outer tube that outer surface is evenly distributed with longitudinal fin is placed in the outer Lower Half of sleeve pipe;

Some dividing plates are housed in b, the sleeve pipe, are filled with worker quality liquid between every dividing plate and dividing plate and casing shoe, be filled with heat-insulating material between first dividing plate in top and sleeve pipe;

Cylindrical arm one end that c, surface are evenly distributed with axial brachypterism sheet passes the interior the lower partition of outer tube insertion sleeve pipe, and a dish is equipped with in the arm below on the electrothermal tube, and angle is greater than 90 degree between its card and electrothermal tube.

During use, its upper end is loaded on the reactor housing, insert in the reactor bottom, connects electrothermal tube power and get final product Fast Heating.

The utility model has the advantages that owing to utilize the heating working medium liquid thermal conductivity, thereby thermal efficiency height, again because of directly inserting heating in the reactor, thereby reactor fills the chuck of conduction oil in need not to add again, housing also need not to adopt the expensive stainless steel material, baffle plate in the also alternative former still, thus the cost of reactor and easy to maintenance reduced.

Another advantage of the present utility model is simple in structure, installation, easy to use.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model user mode figure.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Embodiment:

(referring to Fig. 1,2) inserts in the electrothermal tube 1 that has groove on the outer wall in the middle of the sleeve pipe 2, and the outer tube 3 that outer surface is evenly distributed with longitudinal fin 6 is placed in sleeve pipe 2 outer Lower Halves; Adorn two dividing plates 4 in sleeve pipe 2, will fill into worker quality liquid between its two dividing plate 4 and dividing plate 4 and sleeve pipe 2 bottoms, 2 of lastblock dividing plate 4 and outer tubes fill up heat-insulating material; Cylindrical arm 5 one ends that again surface are evenly distributed with axial brachypterism sheet 6 pass dividing plate 4 bottoms that outer tube 3 inserts in the sleeve pipes 2, below arm 5, a dish 7 are housed on the electrothermal tube 1, make that angle is 120 degree between card and electrothermal tube.
