Abstract
This invention provides a sensor for a membrane rod washing and separation device. The sensor, from the inside out, comprises an inner pipe of the membrane rod washing and separation device, a detection electrode, a radial shielding electrode, a filling material, an electrostatic shielding cover, and a waterproof protective shell. The sensor is located in the residual membrane distribution and collection pipe and the cotton stalk distribution and collection pipe of the membrane rod washing and separation device, respectively. The data acquisition system mainly consists of a micro-capacitance acquisition module, a microcontroller control module, and a switching circuit. The capacitance tomography sensor is connected to the data acquisition system via a data transmission line (waterproofed). The acquired capacitance signal is transmitted to the data acquisition system, analyzed and processed by the data acquisition system, and then transmitted to an imaging computer. The computer uses corresponding algorithms to complete image reconstruction and statistical analysis of cotton stalk and residual membrane information within the image.
