Reaction kettle

Abstract

The invention provides a reaction kettle comprising a kettle body. An external cooling jacket is arranged on the outer side of the kettle body. A variable-frequency motor is arranged on the upper portion of the kettle body. The variable-frequency motor is connected with a speed reducer. A stirring device is connected with the lower portion of the speed reducer and located in the kettle body. A flow guide cylinder is arranged between the kettle body and the stirring device. An internal cooling jacket is arranged outside the flow guide cylinder. The bottom and the top of the internal cooling jacket are connected with a cooling water inlet pipe and a cooling water outlet pipe respectively, and the cooling water inlet pipe and the cooling water outlet pipe extend out of the kettle body. The reaction kettle has the advantages that when the variable-frequency motor works, the turning radius of a horizontal sliding sleeve can be changed through centrifugal force, and therefore the stirring effect is better; the flow guide cylinder and the internal cooling jacket are additionally arranged in the kettle body, the balance of temperature distribution in the kettle body can be greatly improved, and especially the temperature balance on the peripheral area of a stirring shaft is improved; besides, the flow guide cylinder is designed to be in a waist drum shape, reactants can form turbulence, and the reaction is evener and more complete.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a reaction kettle. Background technique [0002] The reaction kettle is one of the commonly used equipment in chemical production, and the most important part is generally the stirring device. At present, the general-purpose stirring device is a stirring blade driven by a motor, but this type of stirring has a narrow range of use, limited stirring capacity, and high energy consumption; Sometimes the material has higher requirements on its reaction temperature. If the reaction temperature exceeds the required temperature, the reaction will not be sufficient, so the temperature needs to be lowered. A common reactor is equipped with a coil for cooling, but the contact area between the coil and the material is limited, so the cooling effect is not obvious. Contents of the invention [0003] The object of the present invention is to provide a reaction kettle to solve th...

Problems solved by technology

At present, the general-purpose stirring device is a stirring blade driven by a motor, but this type of stirring has a narrow range of use, limited stirring capacity, and high energy consumption; Sometimes the material has higher requirements on its reaction temperature. If some reaction temperature exceeds the required temperature, the reaction will be insufficient, so it is necessary to cool down.

A common reactor is equipped with a coil for cooling, but the contact area between the coil and the material is limited, so the cooling effect is not obvious
