Reactor for resin production with scraper

Abstract

The invention discloses a reaction kettle for resin production with a scraping device. The improvement of the reaction kettle is that an outer coil is arranged around the periphery of the kettle body, and the outer coil is formed by a heat-conducting oil inner tube and a steam outer tube. The outside of the outer coil is also covered with a layer of heat insulation; the stirring shaft is provided with a cage stirrer, and the corresponding two sides of the stirring shaft are horizontally fixed with horizontal shafts, and the end of each horizontal shaft is vertically provided with vertical plates. A welding scraper device 1 is fixed on the outer surface of each vertical plate, arc-shaped plates are also arranged on the top and bottom of the stirring shaft, and a welding scraper device 2 is fixed on the convex surface of each arc-shaped plate; the reaction kettle stirring disclosed by the present invention The effect is good, the reaction efficiency is improved, the heating effect is good, the heating speed is fast, the heat preservation effect is good, the heat loss is small, the reaction is complete, and the heating peripherals save the internal reaction space, the maintenance is convenient, the removal of the scale is simple and convenient, and the equipment can last for a long time Normal operation, less difficult to clean.

Description

technical field [0001] The invention relates to a reaction kettle, in particular to a reaction kettle for resin production with a scraping device. Background technique [0002] Reactors are widely used in the chemical industry and are an indispensable and important reactor in the chemical industry. At present, for the preparation of different chemical products, reactors suitable for their production will be manufactured according to their performance. In the reactor Generally, the stirring equipment is the main factor that directly determines whether the reaction is complete. Secondly, it is on the heating device of the reaction kettle. The general heating device is installed inside the reaction kettle. However, there is a disadvantage of setting it inside. It also occupies the reaction space inside the reactor, reducing the effective reaction space; again, the general reactor is heated by steam or heat conduction oil, and after heating, it is transported to the jacket in th...

[0002] Reactors are widely used in the chemical industry and are an indispensable and important reactor in the chemical industry. At present, for the preparation of different chemical products, reactors suitable for their production will be manufactured according to their performance. In the reactor Generally, the stirring equipment is the main factor that directly determines whether the reaction is complete. Secondly, it is on the heating device of the reaction kettle. The general heating device is installed inside the reaction kettle. However, there is a disadvantage of setting it inside. It also occupies the reaction space inside the reactor, reducing the effective reaction space; again, the general reactor is heated by steam or heat conduction oil, and after heating, it is transported to the jacket in the reactor for heating reaction. The heating speed of this method is slow, the heating effect is poor, and the heating time is long, which affects the reaction efficiency; in addition, after a period of reaction in the general reactor, a part of the residual scale will be bonded inside, and the scale will form layers. If it is thicker, it will seriously affect the heat transfer efficiency of the heating device, and then affect the reaction. Therefore, the reactor generally adopts the method of manually entering the interior of the reactor for cleaning after working for a period of time. This method is difficult to handle and is likely to cause dangerous accidents. , and the removal is not thorough enough, and the removal time is longer, which will affect the normal operation of the entire production line
