PURPOSE:To provide an economical collecting method for fine powder deposited in tanks which is used suitably for a synthetic resin film production process such as a disposed film crushing process of multiple series provided with dust collecting facility. CONSTITUTION:Fine powder delivery pipes 14, 24, and 34 and pressurizing gas inlet pipes 15, 25, and 35 are installed at the lower side of storing tanks 10, 20, and 30. Also the fine powder delivery pipes 14, 24, and 34 of the storing tank are connected to a common dust collecting facility 3 at the lower side of which a fine powder collecting port 1 is provided and at the upper suction port of which a suction blower 2 is connected. Then pressurizing gas is led from a pressurizing gas inlet pipe of the storing tank from which fine powder must be collected to disperse the fine powder deposited in the storing tank and drive the suction blower 2 of the common dust collecting facility 3. Thus fine powder in the storing tanks can be collected by the common dust collecting facility. |
