Description

Technical Field

[0001] The utility model relates to the technical field of pipeline inner wall cleaning, in particular to a scraping tool for pipeline inner walls. Background Art

[0002] Currently, in order to improve production efficiency during the production and processing of food, pharmaceuticals, and cosmetics, most food production and processing companies use assembly lines. During assembly line operations, many pipes are required to transport materials. When conveying powders, the fluid dynamics generated by negative pressure in a closed pipe are typically used to transport the powder along the pipe to the processing equipment. Due to the different viscosities of various materials, after the material is discharged from the pipeline of the production equipment, a lot of material often remains at the outlet of the pipe, especially for liquids with slow flow. The residual material in the discharge pipe has always been a headache and troublesome problem, requiring staff to clean it up in a timely manner to ensure production safety.

[0003] In the traditional production process, there is no independent cleaning device designed for the discharge pipe. At this time, workers will scrape it by hand or use a scraper. This treatment method often cannot effectively clean it, which seriously affects the safety of production. At the same time, the scraper has limited length and width, and is not well applicable to certain pipes, resulting in low applicability. Manual scraping of materials often causes cross-contamination and unclean cleaning. The residual materials are exposed to the air for a long time, which will breed bacteria and easily cause product corruption and deterioration, leading to product quality and safety issues.

DETAILED DESCRIPTION

[0017] In order to make the technical scheme and beneficial effects of the utility model clearer, the utility model will be further described in detail below in combination with specific embodiments.

[0018] REFERENCE Figure 1 and Figure 2The embodiment of the utility model discloses a scraping tool for the inner wall of a pipe, including a telescopic rod 1 and a scraper 8. A servo motor 2 is fixed to the right end of the telescopic rod 1, and the output end of the servo motor 2 is connected to a fixed shaft 3. A plurality of scraping assemblies 4 are evenly distributed around the circumference of the fixed shaft 3. The scraping assembly 4 includes a vertical telescopic cylinder 5 arranged perpendicular to the fixed shaft 3. A fixed plate 6 is provided at the output end of the vertical telescopic cylinder 5. A connecting slide groove 7 is provided in the fixed plate 6 to enable the scraper 8 to slide and limit the position. The scraper 8 is a telescopic and adjustable scraper, and an elastic silicone sleeve 9 is sleeved on the scraper 8.

[0019] Reference Figure 1 and Figure 3 The scraper 8 includes an outer scraper 81 and an inner scraper 82. The inner scraper 82 is sleeved and slidably connected to the outer scraper 81. The outer and inner scrapers 81 and 82 are connected by a horizontal telescopic cylinder 83. The outer scraper 81 is fixed in the chute 7, and the inner scraper 82 is slidably connected to the chute 7.

[0020] After the material is conveyed through the pipeline, the residual material on the inner wall of the pipeline is cleaned. The fixed plate 6 and the scraper 8 are both made of stainless steel. The tool is placed in the pipeline and the width is adjusted by the telescopic adjustable scraper 8. The elastic silicone sleeve 9 has a certain elasticity and can be stretched within a certain range. Then the vertical telescopic cylinder 5 is adjusted to make the elastic silicone sleeve 9 fit well with the inner wall of the pipeline.
