Abstract

The invention discloses a porous gas-liquid mixed spraying device. The porous gas-liquid mixed spraying device comprises an injection pipe, wherein the injection pipe is connected with a slurry pump through a pipeline, the injection pipe is of a double-layer structure, a slurry storage pipe is arranged on the outer layer, and an air inlet pipe is arranged on the inner layer; spray holes are formedin the slurry storage pipe; air injection ports are formed in the positions, corresponding to the spray holes, of the air inlet pipe; the inner wall of the slurry storage pipe is not in contact withthe outer wall of the air inlet pipe, two ends of the slurry storage pipe are closed, and a slurry inlet is formed in the slurry storage pipe; and the air inlet pipe is connected with a compressed airpipeline.

Description

technical field [0001] The invention relates to a spraying device for alloy or non-metal molten material casting machines, in particular to a gas-liquid mixing spraying device at porous positions. Background technique [0002] The special material casting machine is a continuous production equipment that casts high-temperature molten alloy molten iron or non-metallic materials into the shape and particle size required by customers. The casting mold is the key part, batch part and consumable part of the casting machine, and its service life is directly related to the production cost of the alloy manufacturer. On the one hand, the service life of the casting mold is determined by its internal quality, that is, it is related to the material, structure, annealing process rationality, etc.; on the other hand, it is determined by the use and maintenance conditions, that is, it is related to the rationality of the spray cooling process and the spraying process. The working conditi...
