Abrasive jet descaling device for steel pipe surface

Abstract

The invention discloses a steel pipe surface abrasive jet descaling device. The steel pipe passes through the steel pipe conveying mechanism, the first-level descaling mechanism, the image detection mechanism, the second-level descaling mechanism, the cleaning mechanism and the air-drying mechanism; multiple sets of roller tables are located under the steel pipe and hold the steel pipe, and the descaling chamber is fixed with a slurry Material ejector, the bottom of the descaling chamber is connected to the slurry collector, the slurry collector is connected to the inlet of the slurry pump through the slurry recovery device, and the outlet of the slurry pump is connected to the slurry ejector; the impeller is installed on the descaling motor, and the impeller The outer side is provided with an impeller casing, which is fixedly connected with the descaling motor and the descaling chamber respectively, and the connection between the lower side of the impeller casing and the descaling chamber is opened, and the slurry pump is connected to the impeller casing through a pipeline. The invention improves the descaling efficiency of the steel plate by using water and metal abrasive scouring, reduces the cost, and has no pollution to the environment; image detection is used to control the number of openings of the descaling mechanism, so that the utilization of material energy is more efficient.

Description

technical field [0001] The invention discloses a steel material descaling device, in particular to a steel pipe surface abrasive jet descaling device. Background technique [0002] At present, the existing steel descaling methods: 1. Tool descaling. Mainly use tools such as wire brushes to polish the steel surface, which can remove loose or raised scale, rust, welding slag, etc. Hand tool descaling can reach Sa2 level. However, the efficiency of tool descaling is low, and product automation cannot be realized. 2. Pickling and descaling. Chemical pickling removes scale, rust, and old coatings. Although chemical cleaning can achieve a certain degree of cleanliness and roughness on the surface, pickling is prone to over-corrosion and hydrogen embrittlement, and acid mist is harmful to the human body and the environment. 3. Shot blasting and descaling. Shot peening is a method of removing metal rust by using compressed air or mechanical centrifugal force as power and frict...
