<p>PURPOSE:To prevent the generation of excessive vacuum between places filled with powdered body absorption pipes in discharge ports by supplying a powdered body and air to the insides of the discharge ports by negative pressure caused by discharging water from the discharge ports through the powdered body absorption pipes and air absorption pipes, and mixing the powdered body with discharged water together with air. CONSTITUTION:When water supplied into an impeller casing 13 is injected to the inside of a stirring water tank 10 through injection nozzles 18d, 18e and 18f, negative pressure is generated in a powdered body mixing space in discharge ports 17a, 17b and 17c. The powdered body 22 is injected into a mixing space of the injection nozzles 18d, 18e and 18f by the negative pressure through a powdered body absorption pipe 19d, a collecting cylinder 20, absorption pipes 19a, 19b and 19c and is mixed with the discharged water. At that time, air is mixed into the discharged water flowing into ejector nozzles in the discharge ports 17a, 17b and 17c through air absorption pipes 52a, 52b, 52c and 52d linked with the air. The powdered body 22 is mixed with the discharged water mixed with air bubbles in the mixing space to discharge it into the water tank 10.</p> |
