固体颗粒输送装置
摘要：
本实用新型公开了一种固体颗粒输送装置。其包括固体颗粒输送入口和固体颗粒输送管，固体颗粒输送入口和固体颗粒输送管之间通过喇叭口部件进行连接，所述固体颗粒输送入口由第一侧面、第二侧面以及格栅组成，第一侧面的两端连接在筒式固体颗粒容器的内壁面上，第二侧面为筒式固体颗粒容器内圆周壁面的一部分，格栅一端连接于第一侧面上部的周边上，另一端连接于第二侧面，其中第一侧面的横截面为弧形，其上开有槽口，格栅的水平倾角α为0°～45°。本实用新型可用于催化裂化再生器上，与现有技术相比，在相同催化剂和输送管操作条件下，可将催化剂循环量提高10％～30％，并且结构简单、易于装置操作。
摘要（英）：

The utility model discloses a solid particle conveyor which comprises a solid particle conveying inlet and a solid particle conveying pipe. The solid particle conveying inlet and the solid particle conveying pipe are connected through a flared part, the solid particle conveying inlet is composed of a first side face, a second side face and a grid, two ends of the first side face are connected on the inner wall of a barrel type solid particle container, the second side face is a portion of the inner circumferential wall of the barrel type solid particle container, one end of the grid is connected on the upper periphery of the first side face, the other end of the grid is connected to the second side face, the transverse section of the first side face is arc-shaped, notches are arranged on the first side face, and the horizontal inclination angle alpha of the grid is 0-45 degrees. The solid particle conveyor can be used for a catalytic cracking regenerator, catalyst circulating quantity can be increased by 10-30% as compared with that of the prior art under operating conditions of same catalysts and conveying pipes, and the solid particle conveyor is simple in structure and easy to operate.
