Smart Sensors And Smart Devices For Centrifuge Applications

Application of smart sensors and smart devices. This has a huge effect on the centrifuge because there are many problems in the automatic continuous production process of the centrifuge. Through the use of smart sensors and smart equipment, the following problems can be effectively improved:

Improve the problem of difficult control of the feed volume. At present, the feed volume control of our continuous centrifuge is mainly judged and controlled by the reactor liquid level, flow meter, material level detection, experience time, etc. These parameters only reflect the amount of solid-liquid mixture. After the mother liquor is thrown out, the solid filter cake Thickness and quality cannot be judged, resulting in excessive cleaning and excessively long or short dehydration time. For this reason, we are developing laser and ultrasonic thickness gauges and weighing systems. Through laser and ultrasonic thickness gauges, we can accurately determine the thickness of the solid filter cake of the centrifuge. The weighing system can measure the solid material in the centrifuge drum filter. According to these parameters, the centrifuge control system can automatically adjust and modify the cleaning volume parameters and dehydration to achieve refined production.

Improve the problem that the moisture content of solid materials is difficult to judge during high-speed separation. Long centrifuge high-speed separation time will cause the residual filter cake to be too thick and affect the secondary separation effect. Short separation time will cause high moisture content of the material, which is easy to transport during transportation. Blockage, waste of energy consumption in the drying process section and other shortcomings. At present, this problem can only be solved through manual observation and time experience. With the future development, the technical development of smart cameras and image recognition or the emergence of online moisture content detection sensors will solve this technical problem.

Improve the difficulty of replacing the filter cloth.The replacement of filter cloth requires work in a confined space. Residual chemical gases and solids in the machine and in the pipeline are harmful to the human body, and the replacement time is long, resulting in long downtime of the centrifuge and other shortcomings. For this reason, we are developing intelligent robotic arms to replace filter cloths, thereby improving the labor intensity of workers and shortening the downtime of centrifuges.

With the increasing development of science and technology, sensing technology has become increasingly mature. In the future, it will be sensed by the equipment itself, even if the concentration, color and temperature of the material have changed. The centrifuge can automatically adjust the feed flow rate, feed speed, separation time, separation speed and other parameters through sensing and control system calculations and analysis. Through real-time monitoring and independent adjustment of material separation data, it is no longer restricted by upstream equipment. The influence of the centrifuge, the final separation effect meets customer needs.

We believe that the rapid development of sensor technology may be another key factor in the upgrade of centrifuge technology. Just as the use of PLC and DCS in centrifuges has realized the progress from manual to automatic, the application of sensor technology in centrifuges is to promote The centrifuge is the key to becoming intelligent.
