) etc. have the following qualities in order to prevent particles from settling during storage and to reduce resistance during pipe transportation. In other words, as the shear rate increases, the viscosity decreases, and if the shear rate remains the same, the viscosity decreases over time, and if the material is left to stand without stirring or flowing, the viscosity gradually returns to its original value. It has pseudoplasticity and chicken tropic properties in that it returns.
而して従来のスラリ貯槽ではスラリに対する格別の払出
し手段を備えていないのが実情である。The reality is that conventional slurry storage tanks are not equipped with special means for discharging slurry.

出すものである。(Function) As described above, in the slurry storage tank according to the present invention, a reserve for dispensing the slurry in the storage tank is provided near the dispensing port in the storage tank and/or in the dispensing piping between the storage tank and the dispensing pump. Since a stirrer is provided, before discharging the slurry in the storage tank, by driving the pre-stirrer, the slurry near the pre-stirrer is stirred to give a slurry to the slurry. reduce the viscosity of
Thereafter, the dispensing pump is operated to discharge the slurry in the storage tank.

In addition, the shape of the stirring blade may be a propeller type, a turbine type, etc. in addition to a metre-type or a screw type. It is also possible to combine Bt of type 2a or higher in one pre-stirrer.
