Spraying type concrete preparation device and preparation method thereof

Abstract

The invention aims at providing a spraying type concrete preparation device and a preparation method thereof. The problem that cement cannot be fully utilized in the preparation process of concrete can be solved, and the utilization efficiency of the cement is improved. The spraying type concrete preparation device comprises a slurry stirring mechanism, a high-pressure slurry spraying mechanism and a concrete stirring mechanism. The cement slurry stirring mechanism comprises a cement slurry stirring barrel and a stirrer driven by a cement slurry stirring motor. The cement slurry stirring barrel is provided with a water and cement feed port and a slurry outlet. The high-pressure slurry spraying mechanism comprises a slurry spraying barrel and a high-pressure slurry pump, the slurry sprayingbarrel is provided with an aggregate feed port, a guide pipe and a slurry spray nozzle, an inlet of the high-pressure slurry pump is connected with the slurry outlet, and an outlet of the high-pressure slurry pump is connected with the slurry spray nozzle through a cement slurry guide pipe. The concrete stirring mechanism comprises a concrete stirring barrel and a concrete stirring motor, the concrete stirring barrel is provided with a feed port and a discharge port, the feed port is connected with the guide pipe, the discharge port is connected with a discharge hopper, and the concrete stirring motor drives the concrete stirring barrel to rotate through a transmission unit.

Description

technical field

[0001] The invention relates to a concrete preparation device and a preparation method thereof, in particular to a spray concrete preparation device and a preparation method thereof. Background technique

[0002] Concrete is a building material. With the rapid development of the construction industry, the amount of concrete used has also been greatly increased. The traditional mixing production process in my country is to mix concrete materials such as water, cement, sand, and stones and then mix them together, regardless of self-falling mixing or forced mixing (single-shaft mixing, twin-shaft mixing, or screw shaft mixing) Mixing) there are factors such as difficulty in controlling the water-cement ratio, dust pollution, gas in the concrete, etc., which cannot solve the operation quality and efficiency of the mixer well, especially in the traditional mixing production process due to the limitation of technology and mixing time in the mixing process , the ceme...
