technical field

The utility model relates to the technical field of reaction kettles, in particular to a chemical reaction kettle.

Background technique

Chemical reactors are widely used in chemical production processes. The key to product quality during operation is the control accuracy of the temperature in the reactor. Due to the complex characteristics of the object, it is difficult to meet the requirements of product quality on temperature by using traditional control methods. Therefore, many production plants, especially private enterprises, still use manual operations, resulting in high labor intensity, poor working environment, large temperature fluctuations in reactors, and low product quality and output. Therefore be necessary to design a kind of chemical reactor.

Utility model content

In order to solve the above problems, the utility model provides a chemical reaction kettle, which overcomes the impact on product quality caused by factors such as large judgment errors of manual operation, untimely response, and operational errors, and can also overcome interference factors other than humans. It can reduce labor intensity, improve working environment, improve production safety, and has strong practicability.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a chemical reaction kettle, including a kettle body, a jacket, a motor, a stirring shaft, a stirring blade, a feeding port, a water injection port, a steam heating device, a temperature sensor, a water Shower device, material level sensor, PLC controller and upper computer, jacket is set outside the kettle body, motor is installed at the center of the top of the kettle body, the motor is connected to the stirring shaft, stirring blades are set on the stirring shaft, and the temperature is set in the kettle body. sensor, material level sensor, the upper part of the kettle body is also equipped with a feed port and a water injection port, the side wall of the jacket is provided with a steam heating device and a cold water temperature control device, and a water shower device is installed outside the kettle body, the motor, the feed port The valve of the water injection port, the steam heating device, the temperature sensor, the water shower device and the material level sensor are all connected with the PLC controller, and the PLC controller is connected with the upper computer.

As a preference, the bottom of the kettle body is also provided with a material outlet and a water outlet.

Preferably, the PLC controller is also connected with an over-temperature alarm.

The utility model has the following beneficial effects: it overcomes the impact on product quality caused by factors such as large judgment errors of manual operation, untimely response, and operational errors, and can also overcome the impact of interference factors other than humans, and can reduce labor intensity. , Improve the working environment, improve production safety, and strong practicability.
