Description

Technical Field

[0001] The utility model relates to the technical field of pipeline flushing equipment, in particular to a water supply pipe network flushing device. Background Art

[0002] As we all know, in the municipal water supply network, due to the uncertainty of users' water use and other reasons, the tap water in some pipe sections flows too slowly or stays for a long time, which can easily cause secondary pollution of the water quality. These pipe sections need to be flushed regularly to reduce the impact on residents' lives.

[0003] At present, the method for flushing the water supply network is generally to first flush it with a large amount of clean water, then soak it in chlorinated water for 24 hours, and then flush it again with clean water until the water quality management department takes samples for testing and passes them. The existing flushing method is generally to directly use a water pump to pump water from the water source and send it into the pipeline to be flushed in the water supply network.

[0004] For different pipelines, the inside of the pipeline is often flushed by high-speed water delivery. The existing water supply network flushing device usually uses a filter to intercept the scale that falls during flushing. However, there is too much scale inside the pipeline. The filter is easily clogged when the scale is intercepted by the filter, and the filter needs to be replaced frequently. The filter is not only difficult to replace, but also increases the cost. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a water supply network flushing device having the following

[0015] Beneficial effects:

[0016] This water supply network flushing device replaces the traditional filter screen by configuring a sedimentation box, a first baffle, a second baffle and a sedimentation plate. The flushing water flows into the sedimentation box, and scale is precipitated inside the sedimentation box. A large amount of scale is precipitated inside the sedimentation box, so there is no need to use a filter screen to filter the scale, thereby reducing the cost of replacing the filter screen.
