Dust collecting device at vertical straining portion of air cushion

Abstract

The invention discloses a dust collecting device at the vertical straining portion of an air cushion. A box body surrounds a vertical straining turnabout drum in a half manner. Dust collecting outer connection pipes are fixed to the portions, located on the front belt face and the rear belt face of a conveying belt, of the side wall of the box body correspondingly. A long and narrow gap is machined in each dust collecting outer connection pipe. A connecting plate II and a connecting plate I are welded to the gaps at a certain angle correspondingly. A polyurethane baffle II and a polyurethane baffle I are fastened to the connecting plate II and the connecting plate I through bolts correspondingly. Holes for the other ends of the dust collecting outer connection pipes to penetrate out are machined in the side walls, corresponding to the dust collecting outer connection pipes, of the box body, connected with an air cushion dust collecting system through a connecting pipe and fixed throughbolts. A hole for the conveying belt to pass through is machined in a bottom plate of the box body. According to the technical scheme, the dust collecting device is installed on a vertical strainingdevice of an air cushion machine, by means of parts such as the box body and the polyurethane baffles, in a relative closed negative pressure space which is formed by the front surface and the rear surface of the conveying belt and is of a horn mouth shape, dust is drawn away by a dust collecting system of the air cushion machine by means of the gaps of the dust collecting pipes, and the overall environment-friendly performance of a conveying machine is improved.

Description

technical field [0001] The invention relates to a dust collection device, which is especially suitable for the return conveyor belt of an air cushion conveyor to be used on a vertically stretched reforming cylinder. Background technique [0002] The air cushion conveyor is an environmentally friendly conveying equipment, and its various environmental performance indicators are at a relatively high level. It is the most important model to consider in areas with strict environmental protection requirements. However, for some special materials at present , the environmental protection performance of the air cushion conveyor has not been perfected, and there will always be different degrees of dust in some places. The vertical tensioning device is an important part. When the drum is running, ash and dust are formed due to the change of the running direction, because there are many parts at the vertical tensioning device, and the shape and installation position are not conducive ...
