In-situ cleaning process of chamber filter presses with sensor-controlled and demand-oriented automation

The content of this paper is the cleaning of filter surfaces from remaining filter cakes. Remaining dirt on filter surfaces is a widespread problem. To counteract this, increasingly automated cleaning systems are being integrated, which clean these surfaces with great cleaning effort. The reduction of the cleaning effort can be achieved by the combination of a camera with a surface contamination detection software. The advantages for the cleaning process are a more efficient cleaning, less produced wastewater and an effective documentation of the cleaning. The cleaning procedure is carried out using 3 steps: It starts with the recording of a picture. Then, an algorithm detects contamination, generates corresponding coordinates and a nozzle path. These coordinates are then approached by means of a xyz table and the contamination is cleaned by a jet stream. Different nozzles and cleaning parameters were tested and their influence on the cleaning effectiveness is discussed in the context of this study.
