Description

Technical Field

[0001] The utility model relates to the field of pipeline processing, in particular to a pipeline socket cleaning device. Background Art

When the annular groove is polished or cut on the inner wall of the socket, a lot of waste slag often remains in the annular groove. For example, the Chinese patent with the patent number CN201710247908.6 provides a method for cleaning the residual core of the ductile iron pipe socket, in which the two ends of the cast ductile iron pipe are placed on two sets of roller groups respectively, and the ductile iron pipe is vibrated by the rotation and vibration of at least one set of roller groups, and at the same time, at least one pneumatic hammer is arranged along the length direction of the ductile iron pipe to knock the ductile iron pipe, and the knocking of the pneumatic hammer causes the large pieces of residual core in the ductile iron pipe socket to fall off; a sand blowing air pipe equipped with a scraper is extended from one end of the ductile iron pipe socket, and the sand blowing air pipe is installed on a trolley. The sand blowing air pipe moves in a direction parallel to the center line of the ductile iron pipe, and the scraper takes out the residual core blocks remaining in the ductile iron pipe; high-pressure air is blown out from the sand blowing air pipe to clean the residue in the ductile iron pipe socket and the straight pipe section. For example, in the above-mentioned prior art ductile iron pipe socket residual core cleaning device, when cleaning, the residue is easily accumulated in the annular groove of the socket, which makes it difficult to blow out.
