Embodiment 1

[0015] Such as figure 1 As shown, the cleaning device for removing oil stains on oil pipelines includes a scraping device 1, an edge grinding device 2, and a cleaning device 3 connected by threads in sequence from front to back; the scraping device 1, the edge grinding device 2, and the cleaning device 3 are all empty cavity structure and the inside of the scraping device 1, the edge grinding device 2, and the cleaning device 3 are connected to each other; The section is a right-angled trapezoid, one end of the spring 5 is connected to the scraper 6, and the other end is connected to the side wall of the hollow rod 4; Leak holes 7 are evenly opened on the outer wall of the hemispherical shape at the lower end; the hollow rod 4 is connected with the edging device 2 through threads.

[0016] In this embodiment, the scraping device 1 , the edge grinding device 2 and the cleaning device 3 are threaded from front to back in sequence, so that the oil stains on the oil wall pipeline...

Embodiment 2

[0018] In this embodiment, on the basis of Embodiment 1, the edging device 2 includes a grinding rod 8, a grinding layer 9 sleeved on the grinding rod 8, and a diamond grinding block 10 evenly arranged on the grinding layer 9; the grinding rod 8 The interior is provided with an internal thread, and the hollow rod 4 is fixed in the lower cavity of the grinding rod 8 through threaded connection.

[0019] After the scraper 6 preliminarily cleaned the oil pipeline, the edging device 2 in this embodiment will further clean the oil pipeline. The diamond grinding block 10 has a strong hardness and will remove the harder stains that the scraper 6 does not remove.

Embodiment 3

[0021] In this embodiment, on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3, the cleaning device 3 includes a connecting rod 11 and a brush 12 evenly arranged on the outer wall of the connecting rod 11; There are external threads, and the connecting rod 11 is fixed in the upper cavity of the grinding rod 8 through threaded connection.

[0022] After the scraping device 1 and the edge grinding device 2 have cleaned the inner wall of the pipeline, the stains will be basically removed, and the brush 12 on the cleaning device 3 will brush away the remaining stains to achieve the effect of thoroughly cleaning the oil pipeline.

Abstract

The invention relates to a cleaning device for removing oil stains on petroleum pipes. The cleaning device comprises a stain scrapping device, an edge grinding device and a cleaning device body which are connected through threads from front to back in sequence; the interiors of the stain scrapping device, the edge grinding device and the cleaning device body are of cavity structures; the stain scrapping device comprises a hollow rod, a spring and scrapping knives evenly hinged to the outer wall of the hollow rod, the longitudinal sections of the scrapping knives are in right trapezoid shapes, one end of the spring is connected with the scrapping knives, and the other end of the spring is connected to the lateral wall of the hollow rod; the hollow rod is of a cavity structure with an opening in the upper end, the lower end of the hollow rod is in a semi ball shape, and leakage holes are evenly formed in the semi-ball-shaped outer wall of the lower end of the hollow rod; the hollow rod is connected with the edge grinding device through threads. In the cleaning device, the stain scrapping device, the edge grinding device and the cleaning device body are connected through the threads from front to back in sequence, the oil stains on the petroleum wall pipes are sequentially washed for three times so as to achieve the high stain removing effect.

Description

technical field [0001] The invention relates to a decontamination device, in particular to a cleaner for removing oil stains from oil pipelines. Background technique [0002] With the continuous development of the petroleum industry, the large number of various oil injection wells has increased the demand for various oil pipelines and water pipelines. After long-term use of oil and water pipelines, there will be many oil stains and dirt on the inner wall of the oil pipelines. Impurities, when the oil and water pipes are used for dynamic monitoring work such as oil well testing and pressure measurement, and when oilfield water injection is relatively clogged, it will affect the monitoring results and bring difficulties to water injection. inconvenient. Contents of the invention [0003] In order to solve the defects that the oil pipeline is easy to generate oil stains to block the pipeline and is not easy to clean, the invention provides a cleaning device for removing oil ...
