Description

Inner half-pipe electric heating reaction kettle

Technical Field

The utility model relates to a reaction kettle, in particular to a reaction kettle for heating materials during organic synthesis reaction. The reaction kettle is mainly applied to the fields of resin synthesis, organic synthesis, paint production and the like.

Background

In resin synthesis, organic synthesis and paint production, a heating reaction kettle is generally required. The heating modes of the heating reaction kettle comprise steam heating, hot water heating, heat transfer oil heating and electric heating, wherein the electric heating mode reaction kettle has the advantages of simple equipment system, low manufacturing cost and wide application; the electric heating reaction kettle in the prior art is mostly characterized in that an electric heating sleeve is fixed on the outer wall of a kettle body of the reaction kettle or an electric heating element is arranged inside the reaction kettle to heat materials. However, the heating efficiency is low due to the small heat exchange area of the outer wall electric heating mode, and the inner electric heating mode has the phenomena of uneven temperature distribution, easy material adhesion and even coking.

Disclosure of Invention

The utility model aims at the defects of the prior electric heating reaction kettle, and provides an inner half-tube electric heating reaction kettle for heating organic synthetic materials by combining mass transfer, heat transfer theory and hydromechanics knowledge.

The utility model discloses an interior half tub of electrical heating reation kettle, include: the reactor barrel (3), go through flange joint's reation kettle upper cover (2) with reation kettle barrel (3), the welding is at reation kettle lower cover (6) of reation kettle barrel (3) lower part, the welding is in the clamp cover (4) of reation kettle barrel (3) outer wall, be located inside the reation kettle barrel, agitator (5) through the coupling joint with outside motor (1), the welding is at reation kettle barrel (3) inner wall, with the axial unanimity and closely range interior half pipe (7), electric heating wire (8) in inserting interior half pipe (7), and the mouth of pipe of welding in reation kettle barrel (3) surface and clamp cover (4) surface. The inner half pipe (7) is obtained by cutting a seamless steel pipe into two parts along the axial direction; the welding is including (mixing) shaft mouth of pipe (a), feeding pipe mouth (b), ejection of compact mouth of pipe (d) on reation kettle barrel (3) surface and the mouth of pipe that presss from both sides cover (4) surface, arranges sediment mouth of pipe (e), thermometer mouth of pipe (g), advances electric heating wire mouth of pipe (h), goes out electric heating wire mouth of pipe (i), advances cooling water pipe mouth (c), goes out cooling water pipe mouth (f).

The working principle of the utility model is as follows:

the utility model discloses an interior half tub of electrical heating reation kettle is at the during operation, reaction raw materials gets into the cavity of reation kettle barrel (3) from reinforced mouth of pipe (b) inside, give electric heating wire (8) switch on simultaneously, drive agitator (5) rotation down in motor (1), reaction raw materials carries out even heat exchange with the produced heat energy of electric heating wire (8) in inserting interior half tub of (7), adjust the power size of electric heating wire (8) through automated control system, can realize the relatively stable of the inside material temperature of reation kettle, thereby realize the heating reaction operation in succession.

In order to ensure the stable temperature of the material and the normal performance of the chemical reaction, especially to cool the material after the chemical reaction is finished, cooling water needs to be introduced into the jacket (4), and the cooling water enters from the cooling water inlet pipe orifice (c) and is discharged from the cooling water outlet pipe orifice (f).

In order to ensure the safe and smooth proceeding of the chemical reaction of the materials in the reaction kettle, a thermometer is required to be installed at the pipe orifice (g) of the thermometer to monitor the reaction temperature of the materials.

The utility model discloses following beneficial effect has:

1. the inner half tube electric heating mode is adopted, the heat exchange area is large, and the heating efficiency is high.

2. Because the inner half pipe is uniformly distributed, the material temperature is uniformly distributed, and the coking phenomenon is not easy to occur.

3. The inner half pipe has the baffling effect of the baffle, so that the materials are mixed more uniformly, and meanwhile, the adhesion phenomenon of the materials on the inner wall can be avoided.
