Description

TECHNICAL FIELD

[0002] Sludge ceramsite is a new type of environmental protection material, which is mainly made by sintering sludge in the urban sewage treatment process at high temperature, and the raw materials of the sludge ceramsite are relatively mixed, including sludge, clay, large particle solids and the like. In order to ensure that the materials are uniformly mixed, the sludge needs to be stirred before being made.

[0003] There are various types of sludge stirring devices, and a stirring barrel with a paddle is usually used for stirring. Since the raw materials of the sludge ceramsite are relatively mixed, it is necessary to separate the large particle solids and the too viscous materials in the sludge during the stirring process.

Therefore, a chemical dissolution method is usually used, or the stirring barrel is tilted or inverted to manually take out the large particle solids, which is very troublesome and not only easily damages the stirring barrel, but also causes accidental injuries if not handled properly, thereby affecting the further recovery and treatment of the sludge. Therefore, it is necessary to provide a sludge stirring device to solve the above problems.
