Reaction kettle

Abstract

The present invention provides a reaction kettle. The reaction kettle comprises a reaction vessel, a motor, a rotating shaft and blades, wherein the motor is arranged at the upper end of the reaction vessel, and the rotating shaft is connected to the motor and extends into the reaction vessel; the reaction vessel comprises an upper head, a middle body and a lower head which are successively connected; a first blade is arranged at the top of the middle body of the rotating shaft; a second blade is arranged in the middle of the middle body of the rotating shaft; a plurality of stirring nails are formed on the side, facing the second blade, of the first blade; a heat transfer liquid inlet is formed in the middle body, and the heat transfer liquid inlet is connected to a heat transfer liquid conduit to introduce a heat transfer liquid from a heat transfer liquid storage tank; the heat transfer liquid inlet is connected to a heat transfer liquid inner pipe; the lower head is provided with a plurality of heating rod insertion slots leading to the heat transfer liquid inner pipe, and heating rods are inserted into the plurality of heating rod insertion slots; and the lower head is provided with a heat transfer liquid outlet leading to the heat transfer liquid inner pipe.

Description

technical field [0001] The invention relates to the field of synthetic resin manufacture, more specifically, the invention relates to a reaction kettle. Background technique [0002] Synthetic resin is completed through polycondensation reaction or polyaddition reaction at a certain temperature and pressure in a reactor. Reactor is the main equipment for resin production. The broad understanding of the reaction kettle is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Among them, for synthetic resins, fractionation columns, condensers, water separators, and dilute kettles are used as supporting equipment for reactors. [0003] Reactors are widely used in the production of resins, paints and other products. The structure of the reaction kettle is generally composed of a reaction vessel (kettle bo...
