Scraping apparatus containing reactor for resin production

Abstract

The invention discloses a scraping apparatus containing reactor for resin production. The reactor is characterized in that an external coil pipe is arranged around the external periphery of the reactor body, the external coil pipe is prepared by sleeving a steam outer sleeve on a thermal conductive inner pipe, the external of the external coil pipe is covered by a thermal insulation layer; a stirring shaft is provided with a cage-type stirrer, horizontal shafts are horizontally and fixedly arranged on two opposite side surfaces of the stirring shaft, the end part of each horizontal shaft is vertically provided with a vertical plate, a scarping device (a) is fixed on the external side surface of each vertical plate, the top part and bottom part of the stirring shaft are both provided with an arc plate, and a scraping device (b) is arranged on the projected surface of each arc plate. The discloses reactor has the advantages of good stirring effect, improved reaction efficiency, good heating effect, rapid heating speed, good thermal insulation effect, little thermal energy loss, and complete reactions, moreover, the heating device is arranged out of the reactor, the inner reaction space is saved, the maintenance becomes easier, the scales can be removed easily and conveniently, the normal operation of equipment can last for a long time, and the cleaning difficulty is reduced.

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
