Abstract

본 발명은 가스량 및 가스의 흐름을 제어하므로서 점결성 분체의 정량공급이 가능케 한 유동층에 의한 분체 공급장치에 관한 것이다.The present invention relates to a powder supply apparatus by a fluidized bed which enables the quantitative supply of caking powder by controlling the amount of gas and the flow of gas.

즉, 가스에 의한 점결성 분체의 공급장치는 본체와 가스 유입구(7), 분산판 (6), 제1분체배출구(4), 오리피스관(8), 유량조절밸브(2) 및 제2분체 배??구(5)와 저장조(3)로 구성되어 있으며, 실린더(1)내의 분체 입자층 표면과 저장도(3) 사이에 균일압력 영역을 형성하여 저장조와 실린더(1)내의 분체입자층을 유동화시키므로서 정량공급이 가능하게 되었다.That is, the apparatus for supplying caking powder by gas includes a main body, a gas inlet 7, a dispersion plate 6, a first powder outlet 4, an orifice pipe 8, a flow control valve 2, and a second powder discharge. It consists of a sphere (5) and a reservoir (3) and forms a uniform pressure region between the surface of the powder particle layer in the cylinder (1) and the storage degree (3) to fluidize the powder particle layer in the reservoir and the cylinder (1). As a result, quantitative supply is possible.
