Abstract

The utility model relates to an internal heating chemical reaction pot. An electrical heating tube is arranged around the inner wall of a pot body, a temperature sensor is installed on a pot cap, and the transmission lead of the temperature sensor is connected with a temperature controller. In the internal heating chemical reaction pot, because the electrical heating tube is adopted to be directly contacted with and to heat the material inside the pot, the electrical heating tube is a generally accepted highly efficient heat conduction element, thus the heating speed is high, in addition, because the material inside the pot is heated firstly, the temperature rise of the pot body is generated by the temperature rise of material inside the pot, therefore, the heating of the pot body is slow and uniform, the crack, the drop-out and the damage of the anticorrosion cushion of the inner wall of the pot body caused by the rapid temperature rise of the pot body can be avoided, and the service life of the pot body is prolonged; in addition, the heating method can reduce the heat loss and improve the heat efficiency; the maintenance of the electrical heating tube is convenient, the automatic temperature adjustment can be realized through the temperature controller, and the labor intensity of the operating personnel can be decreased.

Description

The internal-heating chemical retort

Technical field

The utility model relates to a kind of chemical reaction jar kind equipment.

Background technology

Existing chemical industry generally is made up of tank body, cover, charging aperture, agitating device, heating clamber with retort, and its heating clamber generally is made up of the chuck between the double-level-metal plate that constitutes tank body.Retort allows steam, conduction oil or other heating agents with uniform temperature pass through from heating clamber in the time of need heating, its heat conducts to a jar interior material by the metallic plate and the corrosion protective lining layer of retort inner tank wall, make the material heating, this mode of heating is called external heating type.This mode of heating is because heating agent at first contacts with tank body, and heat is conducted by tank body material in jar then, thereby jar interior material intensification is slower, and has the temperature control hysteresis; In addition because tank body sharply is heated, attached to the corrosion protective lining layer on the inner tank wall because of causing corrosion protective lining slabbing line, come off or damage with the coefficient of expansion of tank body material is inconsistent, thereby the service life of reduction retort; Outer owing to external heating type retort heating location in addition, thereby its heat loss is bigger, the thermal efficiency is lower.Interior reactor heating is common in no chuck equipment, and the still internal heater is the coiled pipe group made from alloy material, and there is following weakness in the still internal heater of this structure: 1. price height, corrosion-resistant, use receive the order short; 2. owing to be overall structure, maintenance needs in the still integral body hang out to hang in, and the still inner surface is to be afraid of collision, and hanging out, hanging in all needs very carefully, keeps in repair very inconvenient; 3 heating carriers normally adopt steam or hot water, are difficult to realize automatic control for temperature control.

Summary of the invention

At the problem that existing retort heater exists, the utility model provides a kind of and can directly heat material in the jar in retort, reduces heat loss, improves the thermal efficiency, and is easy to maintenance, can realize the heating-up temperature internal heating type retort of control automatically simultaneously again.

The purpose of this utility model is achieved in that

A kind of internal-heating chemical retort comprises tank body, cover, agitator, it is characterized in that: be shaped on the electrothermal tube installing hole around tank body, electrothermal tube is housed in jar, temperature sensor is housed on cover, the temperature sensor transfer wire connects temperature controller.

The utility model internal-heating chemical retort, owing to be directly to contact heating with a jar interior material with electrothermal tube, and electrothermal tube is the high-efficiency heat conduction element of generally acknowledging, thereby firing rate is fast, owing to be that a jar interior material is heated earlier, tank body is owing to jar intensification of interior material heats up, thereby tank body is heated slowly and evenly in addition, avoid because of tank body sharply heat up the anticorrosion lining of inner tank wall that causes crackle, come off and damage the service life of prolongation tank body.This in addition mode of heating also can reduce heat loss, improves the thermal efficiency.Electrothermal tube is easy to maintenance, and has temperature controller can realize the temperature automatic temperature-control, reduces labor intensity of operating staff.

Description of drawings

Fig. 1 is an internal-heating chemical retort schematic diagram.

Among the figure: 1 reacting tank body, 2 agitators, 3 electrothermal tubes, 4 temperature sensors, 5 temperature controllers

The specific embodiment

Be described with reference to the accompanying drawings structure of the present utility model.

At conventional belt or the top that does not have a reacting tank body 1 of chuck with the popular response jar cover is arranged, cover is provided with charging aperture and temperature sensor installing hole, be provided with discharge opening in the middle of the bottom of tank body 1, be provided with agitator 2 in the tank body, in tank body 1, around inner tank wall electrothermal tube 3 is housed, its quantity depends on reactor volume, inventory, reaction temperature.Temperature sensor 4 is housed on cover, and the temperature sensor transfer wire connects temperature controller 5, and temperature controller 5 can select for use the also optional usefulness of the temperature controller of single temperature control function to have the temperature control equipment of programming in logic, can realize temperature programmed control.

When retort is worked, add the industrial chemicals that needs processing by charging aperture earlier in jar, the heat of the electrothermal tube 3 in the jar conducts to the industrial chemicals in the tank body 1 rapidly, and meanwhile, the agitator 2 in jar begins rotation and stirs, make the industrial chemicals thermally equivalent, when temperature reaches design temperature, close electrothermal tube by sensor 4 by temperature controller 5 and stop heating, when being lower than design temperature, temperature controller 5 will start electrothermal tube 3, until finishing the total overall reaction process.

Claims (1)

1 one kinds of internal-heating chemical retort comprise tank body, cover, and agitator is characterized in that: be shaped on the electrothermal tube installing hole around tank body, electrothermal tube is housed in jar, temperature sensor is housed on cover, the temperature sensor transfer wire connects temperature controller.
