Abstract

The invention provides a cementing material spraying method and system for compressed air assisted airless spraying, pressing, premixing and granulating. The method comprises the following steps of (1) feeding a cementing material into a spraying hopper of an airless spraying and pressing device; (2) enabling the cementing material to form high-density continuous linear jet flow by utilizing the airless spraying and pressing device, and enabling the high-density continuous linear jet flow to enter a compressed air auxiliary granulating device; (3) shearing the high-density continuous linear cementing material jet flow into particles by utilizing the compressed air auxiliary granulating device, and enabling the granulated cementing material to enter a main spraying device along with compressed air; and (4) pushing the granulated cementing material to be conveyed for a long distance along with a material spraying pipe by utilizing the main spraying device, spraying the granulated cementing material through a spray head, and spraying the cementing material on a working surface. The method can achieve the effects of being good in granulation effect, large in jet density, long in conveying distance, wide in spraying range and uniform in spraying.

Description

technical field [0001] The invention relates to the field of gelling material spraying, in particular to a gelling material spraying method and system for compressed air-assisted airless spray pressure premixing granulation. Background technique [0002] The use of airless spray pressure to spray liquid materials such as paint has been widely used in domestic and foreign coating industries. Its main technical principle is to use high-pressure equipment to apply a pressure of more than 10 MPa to the liquid material, so that the sprayed material will be directly atomized and sprayed on the surface of the sprayed object through the intense impact of the airless spray nozzle and the air. Its characteristic is that the compressed air does not directly contact the sprayed material, the jet density is high, and the atomization effect is good, but the disadvantage is that the spraying distance is short and the delivery range is small. For cementitious materials, the bulk density is...
