Abstract

The utility model discloses a novel chemical reaction vessel comprising a vessel body, a vessel lid and a stirrer. Electrothermal tube mounting holes are arranged along the periphery of the vessel body; electrothermal tubes are arranged in the vessel; internal walls of the vessel body and the vessel lid are both lined with organic materials; a temperature sensor is arranged on the vessel lid; and a transmission conducting wire of the temperature sensor is connected with a temperature controller. The electrothermal tubes which are recognized as high-efficiency heat conducting components heat materials in the vessel by direct contact, and the heating speed is high. In addition, because the materials in the vessel are firstly heated and the temperature of the vessel body is raised because of the temperature rise of the materials in the vessel, the vessel body is heated slowly and uniformly so that the anti-corrosion lining layer of the internal wall of the vessel body is prevented from cracking, falling off and damaging caused by the rapid temperature rise of the vessel body, and the service life of the vessel body can be prolonged. The internal walls of the vessel body and the vessel lid are both lined with the organic materials with low coefficient of heat conductivity, thereby being beneficial to preserving the heat and improving the heat efficiency. The electrothermal tubes can be conveniently maintained, and the temperature controller can realize the automatic temperature adjustment, thereby reducing the labor intensity of operating personnel.

Description

Novel chemical reaction jar

Technical field

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

Background technology

The retort that existing chemical industry is used generally is made up of tank body, cover, charging aperture, agitating device, heating clamber, 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.Generally the overcoating of retort inner tank wall is enamel for glassed steel, though this material has good chemical stability, its thermal conductance height is unfavorable for insulation.External heating mode 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; In addition, because external heating type retort heating location is outer, thereby its heat loss is bigger, and 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, and corrosion-resistant, service life is short; 2. owing to be overall structure, maintenance needs in the still integral body hang out to hang in, and the still inner surface will prevent collision, keeps in repair very inconvenient; 3. heating carrier normally adopts steam or hot water, is difficult to realize automatic control for temperature control.

The utility model content

At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of novel chemical reaction jar, can address the above problem fully.

The technical solution adopted in the utility model is: a kind of novel chemical reaction jar, comprise tank body, cover and agitator, and it is characterized in that: be provided with the electrothermal tube installing hole around tank body, electrothermal tube is housed in jar, inner tank wall also is lined with the machine material again; The cover inwall is lined with the machine material again, and temperature sensor is housed on cover, and the temperature sensor transfer wire connects temperature controller.

Advantage of the present utility model is: directly contact heating with a jar interior material with electrothermal tube, and electrothermal tube is the high-efficiency heat conduction element of generally acknowledging, so firing rate is fast, in addition 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, 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.Inner tank wall and cover inwall all are lined with the machine material again, and its thermal conductivity factor is little, and favourable insulation 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 a structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As shown in Figure 1, on the top of reacting tank body 2 cover 1 is arranged, cover 1 is provided with charging aperture and temperature sensor installing hole, be provided with discharge opening in the middle of the bottom of tank body 2, be provided with agitator 5 in the tank body 2, in tank body 2, along tank body 2 periphery of inner wall electrothermal tube 3 is housed, its quantity depends on reactor volume, inventory, reaction temperature.Temperature sensor 4 is housed on cover 1, and temperature sensor 4 transfer wires connect temperature controller 6, and temperature controller 6 can select for use the also optional usefulness of the temperature controller 6 of single temperature control function to have the temperature control equipment of programming in logic, can realize temperature programmed control.In addition, tank body 2 and cover 1 inwall all are lined with machine material 7 again.

When retort in when work, add the industrial chemicals that needs processing by charging aperture earlier in jar, the heat of the electrothermal tube 3 in jar conducts to the industrial chemicals in the tank body 2 rapidly, meanwhile, the agitator 5 in jar begins to rotate stirring, makes the industrial chemicals thermally equivalent, when temperature reaches design temperature, stop heating by sensor 4 by temperature controller 6 control electrothermal tubes 3, when being lower than design temperature, temperature controller 6 will start electrothermal tube 3.So circulation is until finishing the total overall reaction process.
