Low-consumption energy-saving reaction temperature-varying automatic-overturning crystallization kettle

Abstract

The invention discloses a low-consumption and energy-saving reaction temperature-changing self-turning crystallization kettle, which comprises a sealed box and a kettle body. The shaft and the fixed shaft, the rotating shaft and the fixed shaft are all integrated with the kettle body, the other end of the rotating shaft is rotatably installed on the side wall of the sealed box, and the other end of the fixed shaft is provided with a gear, and the gear and the fixed shaft are integrally cast Formed, the bottom surface of the kettle body is in the shape of a bowl, the main body of the kettle body is in the shape of a round platform with a large upper part and a smaller lower part, a motor is installed in the center of the top of the kettle body, and the output end of the motor is connected with a rotating rod extending into the interior of the kettle body. The device is equipped with an automatic turning device on the inner bottom of the sealed box. After the reaction is completed, the kettle body is turned over and unloaded, and the stirring blade is driven by the motor to scrape off the raw materials attached to the inner wall of the kettle, so as to avoid the raw materials remaining in the kettle body. The body is corroded and the loss of raw materials is reduced. The unloading method is simple and thorough.

Description

Technical field [0001] The invention relates to the field of energy-saving chemical equipment, in particular to a low-consumption energy-saving reaction temperature-variable self-turning crystallization kettle. Background technique [0002] In chemistry, after a hot saturated solution is cooled, solutes are precipitated in the form of crystals. This process is called crystallization. Crystallization is a separation technology with a long history. It is a refining technology commonly used in chemical, pharmaceutical, light industry and other industrial production. It can obtain crystalline solids of a certain shape and size from a homogeneous liquid phase. In the biological products industry such as amino acids, organic acids and antibiotics, crystallization has become an important separation and purification method. Crystallization is a phenomenon in which crystals with a certain shape and regular arrangement of molecules (atoms, ions) are generated from the liquid or gas phase....

AI Technical Summary

Problems solved by technology

The crystallization kettle is a crystallization equipment that needs refrigerated water or refrigerant water to cool down sharply in the interlayer after the material is mixed and reacted. Most of the conventional crystallization kettles adopt the bottom discharge method, and a discharge port is set at the bottom of the crystallization kettle, but this discharge method will cause A large amount of raw materials remain in the kettle body, which will corrode the kettle body, affect the product quality of the next processing, and cause a certain waste of raw materials. Some raw materials need to increase the temperature during the reaction. When cooling and crystallizing, they pass through the interlayer Cooling with chilled water and refrigerant water can easily cause excessive temperature difference and cause damage to the kettle body
