Abstract

The invention discloses a method for conveying a material by using a screw conveyer. The screw conveyer comprises a shell (1) and a screw propeller (2) placed in the shell (1); a material inlet (3) and a material outlet (4) are formed at two ends of the shell (1) respectively; and the screw propeller (2) comprises a shaft and at least three screw blades. Each screw blade comprises a first part and a second part, the screw blades of the first part are the screw blades close to the material inlet (3), the screw blades of the second part are the screw blades close to the material outlet (4), and the screw pitch of the screw blades of the second part is larger than that of the screw blades of the first part. The method comprises the following steps: adding the material into the shell (1) through the material inlet (3) and conveying the material to the material outlet (4) through the screw propeller (2). The method for conveying the material by using the screw conveyer can be used for remarkably overcoming the problem of material blockage in the shell.

Description

Technical field [0001] The invention relates to a method for conveying materials using a screw conveying device. Background technique [0002] Screw conveyors are widely used in the conveying process of solid particles in various fields. The screw conveying device used in the existing solid particle conveying method usually includes a shell, a screw propeller, a feed port and a discharge port; the screw propeller is located in the shell, and the feed port and the discharge port are located in the shell. The two ends of the body; the screw propeller includes a shaft and a spiral blade located on it. There is a gap between the outer edge of the spiral blade and the inner wall of the casing; and all the spiral blades form the same pitch. The screw conveying device has a gap between the outer edge of the screw blade and the inner wall of the housing. Therefore, as the screw blade advances forward when conveying solid particles, the solid particles fall onto the inner wall of the hou...
