Chemical reaction crystallization kettle with long service life

Abstract

The invention discloses a chemical reaction crystallization kettle with long service life. The chemical reaction crystallization kettle with long service life comprises a motor, a motor controller, a seal box and a kettle body, wherein the kettle body is arranged in a seal box; a turnover door is arranged on the top of the seal box; two sides of the kettle body are respectively provided with a rotating shaft and a fixed shaft; each of the rotating shaft and the fixed shaft forms an integrated structure together with the kettle body; the other end of the rotating shaft is rotatably mounted on the side wall of the seal box; the other end of the fixed shaft is provided with a gear; and the gear and the fixed shaft are integrally casted. According to the invention, since the inner bottom surface of the seal box is provided with an automatic turnover device, the kettle body is turned over for discharging after completion of a reaction; and the motor is used for driving stirring vanes to scrape off raw materials adhered on the inner wall of the kettle body, so the raw materials is prevented from leaving in the kettle body and corroding the kettle body, loss of the raw materials is reduced, a discharging manner is simple, and thorough discharging is realized.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a long-life chemical reaction crystallization kettle. Background technique [0002] 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 If the chilled water and refrigerant water are used to cool down, it is easy to cause excessive ...

[0002] 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

And the crystallization kettle needs to use the motor to stir when the material is mixed. The control of the motor is mostly realized by an oscillator or a square wave generator combined with a switching element. It is easy to burn out switching elements such as transistors and MOS tubes
