PURPOSE: A pneumatic conveyor for conveying impurities is provided to prevent impurities from sticking to the inner surface of a container body. CONSTITUTION: A pneumatic conveyor for conveying impurities comprises a container body (10), an inlet valve (20), a guide hopper (30), a compressed air/cleaning water inlet part (40), and a reduce type exhaust pipe (50). Impurities are put into the container body. The container body stores the impurities and transfers the impurities when compressed air is put therein. The inlet valve installed on the top of the container body is opened when the impurities are put into the container body and exhausts the impurities to the bottom when compressed air is put into the container body. The guide hopper is installed on the top of the inlet valve and prevents the impurities from being discharged to the outside. The compressed air/cleaning water inlet part sends compressed air and cleaning water to the top of the container body depending on the output signal of a control part. The reduce type exhaust pipe is installed on the bottom of the container body and guides the exhaust of the impurities. [Reference numerals] (60) Control unit
