Description

Technical Field

[0001] This utility model relates to the field of oil pipe oil stain cleaning technology, and in particular to a device for cleaning oil stains from hydraulic oil pipes in blast furnace front equipment of ironmaking plants. Background Technology

[0002] Currently, during the use of blast furnace equipment in ironmaking plants, due to the large amount of smoke and dust at the equipment site, the outer walls of numerous hydraulic oil pipes in the furnace front equipment easily accumulate a lot of dust and oil stains. It is necessary to clean the oil stains and dust on the surface of the hydraulic oil pipes regularly to prevent corrosion. However, the existing cleaning method is usually manual cleaning with brushes or cloths. This cleaning method is not only time-consuming and labor-intensive, but also unsafe, especially when operating on vertically installed hydraulic oil pipes, and is very inefficient. Therefore, there is an urgent need to design a device for cleaning oil stains from hydraulic oil pipes in blast furnace front equipment to solve the above problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hydraulic oil pipe cleaning device for blast furnace front equipment, which can solve the problems of existing cleaning methods being time-consuming, labor-intensive, unsafe, and extremely inefficient.

[0004] To solve the above problems, the technical solution of this utility model is: this hydraulic oil pipe oil sludge cleaning device for blast furnace front equipment includes a scraper, a control lever and a lifting ring; one end of the control lever is welded to the circular lifting ring, and the other end is connected to the scraper.

[0005] A more specific solution to the above technical solution is that the scraper is a semi-cylinder with a thickness of 2 mm and an outer diameter of 50-80 mm.

[0006] Furthermore, the front end of the scraper is set as a slope with a gradient of 30-45 degrees.

[0007] Furthermore: the control lever is welded to the scraper.

[0008] Furthermore, the control lever is threadedly connected to the scraper via a threaded connecting ring.

[0009] Furthermore: the threaded connecting ring is welded to the end of the scraper, and the end of the operating lever connected to the scraper is provided with threads.

[0010] Furthermore, the scraper, the control lever, and the lifting ring are made of carbon steel.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0012] This utility model has a simple structure and can select a suitable semi-circular cleaning scraper according to the diameter of the hydraulic oil pipe on site. It can fit well against the outer pipe wall for cleaning, and can safely and quickly clean the dust and oil stains on the outer pipe wall. It saves time and effort, improves cleaning efficiency, and avoids rust and corrosion on the surface of the hydraulic oil pipe. It solves the problems of existing cleaning methods being time-consuming, labor-intensive, unsafe, and inefficient. Attached Figure Description

[0016] The labels in the diagram are: 1. scraper; 2. control lever; 3. lifting ring; 4. threaded connecting ring. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0018] Figure 1 and Figure 2 The hydraulic oil pipe oil sludge cleaning device for blast furnace front equipment includes a scraper 1, a control lever 2, and a lifting ring 3.

[0019] One end of the control lever 2 is welded to the circular lifting ring 3, and the other end is connected to the scraper 1; the connection between the control lever 2 and the scraper 1 can be direct welding or threaded connection; for example Figure 3 As shown, when a threaded connection is used, a threaded connecting ring 4 is welded to the scraper 1, and the end of the operating lever 2 connected to the scraper 1 is threaded. By welding the threaded connecting ring 4 to different scrapers, the operating lever 2 can be connected to scrapers 1 of different specifications, thereby saving the number of operating levers 2; in this embodiment, the connection method between the operating lever 2 and the scraper 1 is welding. The operating lever 2 is for hand gripping during operation; the length of the operating lever 2 is 800-1000 mm. In this embodiment, the length of the operating lever 2 is 800 mm, it is a cylinder, and the diameter of the cross-section circle is 20 mm.

[0020] Scraper 1 is a semi-cylinder with a thickness of 2mm. The inner diameter of the semi-cylinder depends on the diameter of the oil pipe to be cleaned, ranging from 50-80 mm. In this embodiment, the inner diameter is 70mm. During cleaning, the inner surface of the semi-circular scraper 1 scrapes back and forth against the outer pipe wall, effectively removing accumulated dust and oil stains from the surface of the hydraulic oil pipe and preventing rust and corrosion. To reduce resistance during cleaning, the front end of scraper 1 can be sloped at an angle of 30-45 degrees (not shown in the figure). The lifting ring 3 is a circular ring used for hanging when not in use and for gripping when in use. The scraper 1, operating lever 2, lifting ring 3, and threaded connecting ring 4 are made of carbon steel.
