Abstract

The invention discloses a rotary type pipeline cleaner which is suitable for plastic-type soft pipelines. The rotary type pipeline cleaner is composed of a cleaning head, a rotary mandrel, a shell body and supports. The cleaning head is welded into a whole by a front end cover, a rear end cover and a separation board for forming a front cavity and a rear cavity, the front cavity is hollow and high pressure water is filled in the rear cavity. A plurality of jet nozzles are installed on the rear end cover of the cleaning head and can be replaced at any time, a certain inclined angle is formed among the axis of the jet nozzles, the axis of a pipeline and the fracture surface tangent direction, and forward and rotary movement is produced. A connecting pipe is connected with a flushing ball through a nylon rope, and the flushing ball rotates to impact and scrape the pipeline to strengthen the cleaning on the pipeline. The outer ends of the three pairs of supports have different diameters through adjustable rods and are supported in the pipeline, and meanwhile the cleaning head is located in the middle of the pipeline. Idler wheels in the supports rotate to reduce the forward resistance of the rotary type pipeline cleaner in the pipeline. All parts in the rear of the rotary mandrel can be disassembled, the length of the rotary type pipeline cleaner is shortened, and an elbow in the pipeline can be cleaned.

Description

Rotary type pipeline cleaner
Technical field
The present invention relates to pipeline cleanser, be specifically related to Plastic pipe-dredging washer.
Background technology
In the discharge tube of sewage vent line and other fluid media (medium), because dirt is in the deposition of duct wall and adhesion, pipeline drift diameter is progressively reduced, as effectively cleared up not in time, when fouling acquires a certain degree, normal use will be had a strong impact on.Existing a large amount of pipe-dredgings, cleaning technique and equipment mainly strive steel, cement concrete material pipeline.
The soft pipeline of Plastic uses in a large number in recent years, existing pipe-dredging, cleaning equipment, easily such pipeline is produced to damage, damages.The existing soft pipeline of Plastic mainly utilizes high pressure water washing method to clear up dirt, and completely by high pressure water washing, length consuming time, water consumption are large, costly uneconomical.
Cleaning head for pipelines in the market, cleaning head is overall processing, and manufacturing process is complicated, and the size of nozzle cannot adjust according to requirements, and nozzle wear cleaning head is then scrapped.
Summary of the invention
The object of the invention is to: a kind of rotary type pipeline cleaner being applicable to the soft pipeline of Plastic is provided, solve the soft pipe-dredging of Plastic, cleaning problem, the consumption of water of increasing work efficiency simultaneously, reduce.
Technical solution of the present invention is: rotary type pipeline cleaner comprises cleaning head, rotary core shaft, housing, holder part.
