Description

AREA OF APPLICATION AND PRIOR ART

The invention relates to a system for preventing Dickstoffverstopfung in a thick matter delivery line when pumping thick matter in the thick matter delivery line.

TASK AND SOLUTION

The invention is based on the object of providing a system for preventing a thick matter clogging in a thick matter delivery line when pumping thick matter in the thick matter delivery line.

The invention solves this problem by providing a system having the features of claim 1. Advantageous developments and / or embodiments of the invention are described in the dependent claims.

The system according to the invention is designed to avoid a, in particular partial or complete, thick matter clogging in a thick matter delivery line during or during pumping of thick matter in the thick matter delivery line. The system has a, in particular electrically, controllable clogging prevention device and a, in particular electrical, control device. The obstruction avoidance device is designed for, in particular autonomous or autonomous or automatic, avoidance of thick matter clogging in the thick matter delivery line. The control device is designed, when pumping in thick matter, to control the blockage avoidance device independently or autonomously or automatically in a pumping control mode in such a way that the blockage avoidance device avoids a thick matter blockage, in particular independently.

Thick material can be a mixture of liquid and solid components. In particular, thick matter may comprise or be concrete, cement, plaster, mortar, screed and / or sludge. In a promotion of thick matter in the thick matter delivery line, the liquid and solid components can be separated so that a dry, stuck part, namely a Dickstoffverstopfung, can arise, which can block or prevent further promotion.

So far, could be detected by an operator only by the lack of thick matter at one end of the thick matter delivery line a Dickstoffverstopfung. As a rule, thick matter clogging has already been very pronounced at this time. Then the work had to be interrupted and the thick matter clogging in the thick matter delivery line had to be manually searched by the operator and solved. In most cases, the thick matter delivery line had to be opened in a time-consuming manner, with considerable dangers for the operator, in particular due to thick matter suddenly spouting out of the thick matter delivery line. Only after a successful solution of the thick matter clogging could be continued with the work, in particular the promotion.

Now, the system according to the invention enables the avoidance of a thick matter blockage, in particular by the independently controlling control device. In other words, the operator does not need to avoid a thick matter clogging, in particular not to control the control device or the clogging prevention device. Thus, the system allows loading of the thick matter delivery line and / or other components to reduce or even prevent operator risk and / or disruption or downtime.
