Description

A sand recovery device for asphalt waterproof membrane

technical field

The utility model relates to the field of waterproof coiled materials, in particular to a sand recovery device for asphalt waterproof coiled materials.

Background technique

Waterproof membrane is an indispensable building material in today's social buildings. It is used to enhance the waterproofness of buildings and prevent groundwater from invading building foundations. In order to cope with different building environments, a variety of different waterproof membranes have been developed. Among them, waterproof membranes with sandy surfaces have high tensile strength, strong foundation adhesion, and sandy surfaces are bonded to protective layers and cement sections. Good features, excellent performance.

Patent No. CN201621172928.9 discloses a surface sand-coated waterproof membrane sand recovery device, which solves the problems of recycling excess sand and fine dust pollution to the working environment during the production of surface sand-coated waterproof membranes. The key point of the technical solution is that a surplus material storage hopper is arranged under one end of the conveyor belt, a cleaning brush is arranged on the surplus material storage hopper, the bottom of the cleaning brush is connected to the surplus material storage hopper, and the cleaning brush conflicts with the lower belt surface of the conveyor belt.

Although the above-mentioned device can remove and recycle the sand on the conveyor belt, the removal is not thorough enough. It is only cleaned by the cleaning brush. If some sand attached to the conveyor belt is not removed in time, it will accumulate more and more, which will affect the subsequent sanding work. , At the same time, the dust is relatively large and the pollution is serious during the sanding process, so the dust removal device of the spraying sanding system becomes the top priority.
