Steel plate descaling, cleaning and air drying device

Abstract

The invention discloses a descaling, cleaning and air drying device of a steel plate. The descaling, cleaning and air drying device is that 1-3 sizing material ejection descaling mechanism, a steel plate washing mechanism and an air drying mechanism are sequentially arranged and connected, and the steel plate horizontally sequentially passes through the 1-3 sizing material ejection descaling mechanisms, the steel plate washing mechanism and the air drying mechanism; a descaling sizing material recovering circulating mechanism is respectively connected with the sizing material ejection descaling mechanisms and the steel plate washing mechanism, and descaling chambers arranged on the upper and lower parts of the steel plate are both fixedly provided with two sizing material ejectors which have same structure and are parallelly arranged. The descaling, cleaning and air drying device provided by the invention has the advantages that the descaling, cleaning and air drying device is efficient, environment-friendly and energy-saving, the secondary pollution is not generated, water and metal abrasives are utilized to descale the upper and lower surfaces of the steel plate, the descaling efficiency of the steel plate is improved, the cost is reduced, no pollution is generated to environment, ultrasonic wave impulse high pressure water is adopted to flush the surface of the steel plate, the power of a water pump is reduced, and the descaling, cleaning and air drying device is energy-saving and effective.

Description

technical field [0001] The invention relates to a descaling, cleaning and air-drying device, in particular to a steel plate descaling, cleaning and air-drying device. Background technique [0002] Currently available steel plate descaling methods: [0003] 1. Tool descaling mainly uses wire brushes and other tools to polish the steel surface, which can remove loose or lifted scale, rust, welding slag, etc. Hand tool descaling can reach Sa2 level. However, the low efficiency of tool descaling cannot realize product automation, and it is relatively harmful to human body. [0004] 2. Pickling and descaling Chemical pickling can remove 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. [0005] 3. Shot peening and descaling Shot peening is a method of removing metal rus...

AI Technical Summary

Problems solved by technology

However, the treatment of the steel plate by shot peening is easy to deform the workpiece, causing great environmental pollution, and can only be operated in a closed space.

[0006] 4. Slurry descaling. Although U.S. patents US7601226 and US6814815 have made corresponding descriptions on steel plate descaling and cleaning steel plates with steel brushes, the steel plates cleaned by this method will immediately return to rust when in contact with air, which cannot be removed with steel brushes. There are traces of secondary repair on the surface of the steel plate, and the fine particles on the surface cannot be completely removed with a steel brush and normal pressure water

The surface of the produced steel plate is relatively dirty
