Steam Heating Resin Reaction Kettle

Steam heating Resin Reaction Kettle Introduction

The steam-heated resin reactor is actually a small kettle, that is, it is directly required according to heating and its evaporation, cooling and its low-speed, high-speed mixing.

For the structural design and parameter design of the steam-heated resin reactor, it is necessary to strictly process, test and conduct trial operation according to the corresponding standards.

The steam-heated resin reactor consists of a pot body, upper and lower ends, a stirrer and a heating (cooling) jacket, and then there is a direct insulation layer, a support, and a transmission device and a shaft sealing device.

Feature:

Steam heated resin reactors are used to produce critical equipment for unsaturated polyester resins, rosin resins, epoxies, phenolic resins, alkyds, paints and adhesives.

According to the level of the reaction temperature, it is divided into a high temperature resin reactor (150 ° C - 300 ° C) and a low temperature resin reactor (60 ° C - 150 ° C).

Steam-heated resin reactors have a common reactor volume of 0.5-5 m3, and are mostly lined with acid-resistant enamel materials at a relatively low price. The kettle body is a sandwiched cylinder, an elliptical bottom, and the top cover is a spherical body with a plurality of apertures, and the fasteners are used to join the two together by a flange. The reaction kettle is normally open to the atmosphere, and is used for the production of dehydrated rubber and a reaction kettle using vacuum feed. The negative pressure is generally not more than 0.1 MPa, the thickness of the wall is generally 8-16 mm, and the thickness of the outer wall is 5- 10 mm, the larger the volume of the reactor, the thicker the wall. The pressure of steam or cooling water received in the interlayer generally does not exceed 0.3 MPa.

Production equipment：

The agitator is located in the center of the reaction kettle. Its structure is in the form of anchor, paddle and frame structure. It adopts more anchor structure, which can make the upper and lower layers of the material evenly mix. The rotation speed of the agitator is generally Within 40-100r/min, the rotation speed is fast, although the stirring efficiency is high, it is easy to generate foam. The rotation of the agitator is driven by the motor through a speed reducer. The type of reducer is mostly worm gear reducer, which is characterized by simple structure, stable transmission and convenient maintenance. At present, the ideal reducer is a balance needle reducer, which is popular due to its compact structure, small size and long service life.
