ABSTRACT:
The invention relates to a device for cleaning the pipes of heat-exchangers by means of cleaning bodies, generally sponge balls. The removal and reintroduction of the cleaning bodies occurs with the aid of a device installed in the outlet pipe, which consists of a casing (1) with one or two screens (2) arranged within it. The screens (2) end on the downstream side at a pipe (3) with an opening (4). Inside this pipe (3) there is another pipe (5) with an opening (6) which preferably rotates continuously. The cleaning bodies (9) are collected in the inner pipe (5). A pressure water pipe (7) and a cleaning body outlet pipe (8) are connected to the outer pipe (3). When the inner pipe (5) is in the appropriate position, the cleaning bodies (9) are washed out of the inner pipe (5) by pressure water and introduced into the inlet pipe of the heat-exchanger via the cleaning body outlet pipe (8). A lock (11) is built into the cleaning body return pipe in order to introduce and remove the cleaning bodies (9).
