Description
Technical Field
The invention relates to a pipeline cleaning technology, in particular to a pipeline cleaning device and a pipeline cleaning method for cleaning submicron metal dust.
Background
The explosion cavity pipeline is 2 x 106The mounting carrier of the V-wire explosion-break switch is required to have good insulating ability. However, after each experiment, a large amount of metal dust adheres to the inner wall of the explosion cavity pipeline, and the insulating capability of the inner wall of the explosion cavity pipeline is seriously influenced. Cleaning of the explosion chamber tubes is therefore required.
The explosion chamber is usually cleaned manually by a long rod with a cleaning brush head tied to one end. In addition to the need for continuous replacement of the brush head during cleaning, the brush head and the inner wall need to be squeezed tightly to ensure cleaning quality, which makes it difficult to move the brush head back and forth and rotate the brush head. Meanwhile, metal dust is firmly adhered to the inner wall, and is difficult to clean completely by manpower, especially the far end (closed end) position of the explosion cavity. The existing manual cleaning mode is time-consuming and labor-consuming, and the working efficiency is seriously influenced. Therefore, a device for cleaning the inner wall of the explosion cavity needs to be developed so as to ensure that the inner wall of the explosion cavity is clean and the experimental work efficiency can be improved.
Currently, the existing pipe cleaning apparatuses include the following documents [1] to [6 ]:
chinese patent publication No. CN203817006U, entitled pipe cleaning machine;
chinese patent publication No. CN203565438U, entitled pipe cleaner;
chinese patent publication No. CN203635573U, entitled gas pipeline cleaning system;
chinese patent publication No. CN202527423U, entitled multifunctional pipe cleaning device;
chinese patent publication No. CN202343518U, entitled pipe cleaning device;
the application of the shallow-talk bidirectional adjustable cavity jet device in pipeline cleaning [ J ], China equipment engineering, 2020, 01, p 177-178.
The pipeline cleaning machine described in the document [1] utilizes high-pressure gas to spray cleaning agent into the pipeline, and then cleans the pipeline and utilizes a liquid pumping motor to pump waste liquid, so as to achieve the purpose of cleaning the pipeline. The pipeline cleaner described in the document [2] is composed of a brush head, a power device for driving the brush head to rotate and a transmission device for connecting the power device and the brush head, and is mainly used for cleaning a heat exchange pipe. The gas pipe cleaning system described in document [3] washes impurities in the gas pipe by injecting high-speed steam. The multifunction piping cleaning apparatus described in document [4] cleans a piping by using a high-pressure gas jet liquid. The pipeline cleaning device described in the document [5] adopts a soft elastic cleaning ball, which is put in from one side of the pipeline, tightly attached to the inner wall of the pipeline, and pulled out from the other side of the pipeline, thereby achieving the purpose of cleaning the pipeline. The bidirectional adjustable cavity jet device described in the document [6] utilizes water flow pressure and elastic blades to cling to the pipe wall to generate high-speed water flow to crush and flush away dirt, and the device can move forwards and backwards and is mainly used for cleaning the water conveying pipeline of the oil field.
The above documents all describe special cleaning devices for cleaning pipes for different working conditions. The main cleaning object of the apparatuses described in documents [1] to [6] is dirt generated on the inner wall by long-term transportation of the raw material in the pipeline, and most of the cleaned dirt can be discharged through the pipeline. Moreover, the devices are designed with various special structures and functions according to the working conditions of the devices, and the structures are complex. The length of the explosion cavity pipeline is about 4m, the diameter of the pipeline is about 150mm, one end of the explosion cavity pipeline is closed, pollutants on the inner wall of the explosion cavity pipeline are metal dust formed after the metal wire explodes, the metal dust is tightly adhered to the inner wall, and the metal dust is difficult to remove. In addition, in order to ensure the insulating property of the inner wall, the whole cleaning process can not use water and other liquids, but only use volatile organic liquids such as alcohol and the like. Such liquids cannot be used in large quantities because they are flammable. Therefore, the existing pipeline cleaning device is not suitable for cleaning the pipeline of the explosion cavity.
