Municipal sewer desilting device

Abstract

The invention relates to a municipal sewer desilting device which solves the problems that in the prior art, the cleaning efficiency of dry sludge adhering to the wall of a pipeline is low, and a scraper rotating mode is not suitable for removing sludge containing obstacles in the pipeline. The technical scheme for solving the problems is as follows: the municipal sewer desilting device comprisesa bracket, wherein a rotating shaft is arranged on the bracket, a conical sleeve is arranged on a rotating shaft, a scraper frame is arranged on the conical sleeve; a scraper is arranged on a scraperframe, a sliding block is arranged on the rotating shaft, poke rods are arranged on the sliding block, a first sleeve is arranged above the conical sleeve; a through hole coaxial with the rotating shaft is formed in the upper end of the first sleeve, a plurality of vertical baffle plates in one-to-one correspondence with the poke rods are uniformly distributed on the circumference of the through hole, and after the sliding block drives the poke rod to move downwards, the poke rods can be matched with the baffles, so that the sliding block rotates along with the rotating shaft to drive the conical sleeve to rotate together, the sliding block drives the poke rods to move upwards, and after the poke rods are separated from the baffles, and the conical sleeve rotates reversely to reset. The device is novel in concept, ingenious in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of sewer dredging machinery, in particular to a municipal sewer dredging device. Background technique [0002] When the sewer contains silt, a high-pressure water gun is usually used to impact the silt in the pipe to dredge the sewer. In addition, there are also dredging vehicles to suck out the silt in the sewer through the high-pressure pipe. These two methods are more effective for the silt containing water in the sewer However, it does not work for the dry sludge that has dried on the sewer pipe wall and adhered to the pipe wall. Although the sludge on the pipe wall can be removed by using a high-pressure water gun, it requires a lot of water resources and is easy to cause water pollution. The waste of waste, using the dredging truck to suck out the sludge in the sewer through the high-pressure pipeline, cannot treat the sludge on the pipeline wall; [0003] For the cleaning of the sludge on the inner wall of the...
