Problems solved by technology

Li Shengli [4] Introduced to change the centrifuge controlled by relays to PLC controlled by Mitsubishi series, which solved some problems caused by relay control and basically achieved safety and stability, but it was difficult to debug and maintain
Guo Hongbin [5] Yang Peiwen [6] etc. introduced the use of Siemens series PLC combined with frequency converters for speed regulation control. Although good results can be achieved, frequency converters are expensive. If mass production will increase the company's huge cost

Abstract

The invention discloses a PID-based double-stage pusher centrifuge control device and method. The device is designed based on the principle of simpleness, practicality, stability and low cost; centrifugal revolution number thereof is lower than 3000r / min; and the device is suitable for separating suspension liquid of crystalline and fibrous material of particles, and is also suitable for materials, which need to the washed and suspension liquid of which is high in solid content. Hardware of the device is formed by a PLC, a main motor, an oil pump motor, a power supply module, a sensor, an electric appliance protection switch and some peripheral circuits. The device is stable to work, is easy to maintain and improves production efficiency and product quality; meanwhile, compared with other control systems adopting the PLC and a frequency converter, the device saves cost, and is easy to operate and maintain; and the device has a manual control mode and an automatic control mode, so that through the flexible control modes, a user can carry out operation very conveniently.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a PID-based two-stage pusher centrifuge control device and method. Background technique [0002] Centrifuges are widely used in food, pharmaceutical, agrochemical, chemical and other industries, and their development trend is toward intelligence, energy saving, specialization, and large-scale development [1] . The centrifuge control system of the present invention is suitable for the suspension of crystalline or fibrous materials in the separation of particles, such as potassium nitrate, potassium chloride, ammonium bicarbonate, sodium sulfate, potassium sulfate, polyethylene, polypropylene, cellulose, etc. Separation of materials. [0003] The principle of the centrifuge is to use centrifugal force to separate the solid particles in the suspension from the liquid, or to separate two different densities and immiscible liquids in the emulsion; it can also be used to remove the l...
