Steel belt pass-through shot blasting machine

Abstract

The invention relates to a pass-type shot-blast cleaning machine for a steel strip. According to the pass-type shot-blast cleaning machine, steel strip clamping devices are mounted on opposite sidewalls of a shot-blasting chamber, steel strip supporting devices, which form shot-blasting stations correspondingly with the steel strip clamping devices, are arranged in the shot-blasting chamber, and at least four shot blasters which are pointed to the shot-blasting stations are mounted on the shot-blasting chamber above and below the shot-blasting station in pairs; the at least four shot blasters are symmetrically arranged along the direction vertical to the steel strip conveying direction; the shot blasters are mounted obliquely, an included angle between the shot blasters located above the shot-blasting stations and the horizontal plane where the shot-blasting stations are located is alpha, an included angle between the shot blasters located below the shot-blasting stations and the horizontal plane where the shot-blasting stations are located is beta, an included angle between the shot blasters and a vertical plane along the steel strip conveying direction is gamma, and the included angles respectively meet the conditions that the alpha is not smaller than 15 degrees and not greater than 25 degrees, the beta is not smaller than 33 degrees and not greater than 43 degrees and the gamma is not smaller than 11 degrees and not greater than 21 degrees. The pass-type shot-blast cleaning machine can be used for carrying out shot-blasting treatment on the steel strip on the shot-blasting station from all angles and is high in efficiency and good in cleaning effect.

Description

technical field [0001] The invention relates to surface treatment equipment for steel strips, in particular to a steel strip pass-through shot blasting machine. Background technique [0002] The steel belt pass-through shot blasting machine transports the steel belt forward through the unwinding mechanism. When the steel belt enters the shot blasting room, the shot blaster starts to work sequentially. After shot blasting, the scale, dirt and other attachments on the steel surface are cleaned up, and the treated surface can reach Sa2-2.5 level. The working mode of the shot blasting machine is a continuous cycle. After the shot blasting time reaches the requirement, the shot blasting machine will stop working automatically. The pellets thrown by the shot blasting machine are collected and processed by the circulation processing system, and continue to be used by the shot blasting machine. [0003] In the prior art, the main disadvantage of the steel belt pass-through shot bl...
