Abstract

The invention discloses a correcting device of a belt filter press, comprising a sensor, a controller and an executing component, the sensor comprises an excursion sensor and a displacement sensor that adopt angle sensors, the executing component comprises an electric engine steering controller, an excursion-regulating electric engine, a transmission mechanism and a correcting roller, the angle sensors of the displacement sensor and the excursion sensor are respectively mounted right above standard positions of a filter belt and the correcting roller; the angle detection signals of the filter belt and the correcting roller, which are detected and output by the angle sensors, are transformed by the controller to output a control signal for controlling the correcting motions of the executing component. By adopting the semi-continuous correcting way having correcting roller pulse type regulation and using the angle sensors to continuously detect the displacement signal, the invention overcomes the flaws in the prior art and has the advantages of reasonable structure and simple control as well as achieves, at very low manufacturing cost, the continuous correction control precision in the continuous correcting device which requires high cost.

Description

technical field [0001] The invention relates to a deviation correcting device, in particular to a deviation correcting device for a belt filter press used for correcting the deviation of the filter belt of the belt filter press. Background technique [0002] During the operation of the belt filter press, due to the inconsistency between the installation error of the drive roller and the inconsistency of the lateral tension of the filter belt during operation, the filter belt often deviates, which affects the normal operation of the belt filter press, and a deviation correction device is required To correct the deviation of the filter belt. The deviation correction device is mainly composed of a sensor, a controller and a deviation correction execution part. According to the control mode, there are two types: switch type and continuous type. The switch-type deviation correction device is easy to control, but the deviation correction accuracy is relatively low. Continuous de...
