Compressed air assisted airless pressure spraying premixing granulation equipment and binding material spraying system

Abstract

The invention provides compressed air assisted airless pressure spraying premixing granulation equipment and a binding material spraying system, which are applied to binding material spraying. The premixing granulation equipment comprises an airless pressure spraying device and a compressed air assisted granulation device, wherein the airless pressure spraying device comprises a spraying hopper and a hydraulic pumping device connected to the spraying hopper through a high-pressure pipeline; an airless pressure spraying sleeve head is connected to the bottom of the spraying hopper; a pluralityof airless pressure spraying holes are arranged in the bottom of the airless pressure spraying sleeve head; the compressed air assisted granulation device comprises a granulation cavity and an auxiliary air compressor connected to the granulation cavity; the airless pressure spraying sleeve head is located in the granulation cavity; the granulation cavity is cylindrical; cable-stayed fixing bladesare arranged on the inner wall of the granulation cavity; and compressed air in the granulation cavity forms a tangential airflow field under the action of the cable-stayed fixing blades. According to the compressed air assisted airless pressure spraying premixing granulation equipment and the binding material spraying system, the granulation effect, the jet density, the conveying distance, the spraying range and the spraying uniformity of the technology are uniformly improved in the radial direction of the fluid.

Description

technical field [0001] The invention relates to the field of gelling material spraying, in particular to a compressed air assisted airless spray pressure premixing granulation equipment and a gelling material spraying system. 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 i...
