The invention discloses a pipeline cleaning robot. The pipeline cleaning robot comprises traveling driving mechanisms, a sweeping mechanism, an impurity recovery mechanism and a trunk body. The two ends of the trunk body are both provided with the traveling driving mechanisms. The impurity recovery mechanism is mounted at one end of the trunk body. The sweeping mechanism is mounted in the middle of the trunk body. The sweeping mechanism comprises a rotation driving assembly and a plurality of first sweeping assemblies. Each first sweeping assembly comprises a sweeping brush, a first sweeping arm and a second sweeping arm. The pipeline cleaning robot achieves the automatic cleaning effect of pipelines without manual operation, greatly saves manpower, and is suitable for cleaning of both straight pipelines and curved pipelines, wide in application range, economical and practical.

The disclosure relates to an apparatus for cleaning piping and a method of cleaning piping. In particular, the apparatus may be a "pig", a device for insertion into a pipe for removing deposits from the inner surface of the pipe. The disclosure is particularly applicable in the field of alumina production. In this field, it is common to obtain alumina from bauxite by grinding the bauxite, mixing this with caustic liquor to form a slurry, and heating the slurry. This leads to the alumina trapped in the bauxite dissolving to form a supersaturated solution of alumina in the caustic liquor with a suspension of the residue from the bauxite. Using known methods, alumina can be recovered from such a solution. The disclosure provides a pipe cleaning device (1) for removing deposits from the inner surface of a pipe. The pipe cleaning device (1) comprises a propelling piston (10) and a cleaning tool (100) attached to the propelling piston (10), wherein: the cleaning tool (100) comprises a main body (110) and a plurality of circumferentially spaced arms (200), pivotably attached to the main body (110) and urged by an urging force to pivot away from a longitudinal axis of the main body (110); each arm (200) has an insert (300) with a plurality of teeth (400) on its distal end defining a working surface for engaging deposits on the inner surface of the pipe; and the teeth (400) have a distal end and a cutting edge spaced from the distal end.
