Abstract

The invention discloses a control method and system based on the material level of the silo. The height of the material level of the silo is measured by a probe, and the height signal is transmitted to the material level sensor. The material level sensor compares the received material level height with the high level of the material level The set value or low set value is compared, and the material level status signal is output according to the comparison result, and then the controller is used to control the opening of the sludge pump pumping displacement valve to adjust the speed of the pumping process of the pump body, and The speed of the screw feeder is controlled according to the corresponding ratio, so that the conveying speed of the screw feeder matches the pumping speed, so as to ensure the normal working process of the system and realize the automatic control of the pumping speed.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a control method and system based on the material level of a silo. Background technique [0002] The pump body is generally used in factories such as sewage treatment plants, and the working environment is relatively harsh. During the normal operation of the factory, the site does not need human control, but the work site is monitored and controlled through remote operation. During the normal pumping process, the pump body and the screw feeder do not pump according to a fixed displacement. Even if it is adjusted, it is not to artificially control the pumping speed of the pump body, but to achieve the pumping displacement. automatic control. The existing pumping system can use the anti-rotation level gauge to measure the height of the material level in the silo. The anti-rotation level gauge has rotating blades. When the material level is high, it will touch the material, pr...
