When the exhaust piston of the exhaust seat 403 contracts, the exhaust piston 402 opens the channel between the exhaust cylinder and the inner cavity of the exhaust seat, and adjusts the air pressure of the exhaust seat section to ensure the material to fall smoothly.
The working method of the double butterfly valve remote slurry spraying machine comprises the following specific steps: when the gate valve mechanism and the second butterfly valve mechanism open the valve simultaneously, the material in the hopper enters between the gate valve mechanism and the first butterfly valve, the material between the first butterfly valve mechanism and the second butterfly valve mechanism enters into the material cavity of the rotor mechanism, and the valve of the first butterfly valve mechanism is closed to form sealing; the materials in the material cavity are continuously sprayed and conveyed through the discharge hole along with the rotation of the rotor mechanism. Then the gate valve mechanism and the second butterfly valve mechanism close the valve simultaneously to form sealing, the first butterfly valve is opened, the material falls into the position of the exhaust mechanism from the upper part of the first butterfly valve, and at the moment, due to the early sealing, the exhaust piston of the exhaust device is opened, so that the material is ensured to fall smoothly; according to the method, the gate valve mechanism, the first butterfly valve mechanism and the second butterfly valve mechanism are matched with each other to complete sealing in the blanking process, so that the generation of dust is reduced, and the spraying distance is increased. The conical distributor distributes the falling materials into each material cavity of the rotor, so that the continuity of concrete conveying and guniting is realized, and guniting pulses are reduced.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
