<p>PROBLEM TO BE SOLVED: To provide a fluid stirring device which can be readily mounted to a general purpose sand pump, and has excellent slime processing efficiency, and a sand pump using the same.SOLUTION: A fluid stirring device is configured to use: an extended rotary shaft of an underwater sand pump as a power source; an upper water flow limit plate provided above a screw so that the water flow around the screw may not circulate; a suction pipe isolated from the screw through which water is supplied to the screw; and a lower water flow guide member under the screw to spread a downward water flow caused by the screw.</p> |
