The invention relates to a screw-pitch-variable hole-pitch-variable drum screen separator. The screw-pitch-variable hole-pitch-variable drum screen separator comprises a screw conveyer, a screen support, a cylindrical screen and an air classification chamber. The screw conveyer is installed at one end of the screen support, and the center shaft of the screw conveyer penetrates to the other end of the screen support from one end of the screen support to be supported, installed and fixed. The cylindrical screen is installed on the center shaft of the screw conveyer, a feeding port of the cylindrical screen is communicated with a discharging port of the screw conveyer, and internal screw blades are arranged on the inner wall of the cylindrical screen. Screen holes are formed in the cylindrical screen and used for forming a pill material flowing curtain when pill material falls in the conveying process. The air classification chamber is arranged under the cylindrical screen and used for separating the pill material flowing curtain through air classification. The screw-pitch-variable hole-pitch-variable drum screen separator is characterized in that the screw pitch of the internal screw blades on the cylindrical screen becomes smaller in the heading direction of the pill material, and the pitch of screen holes in the cylindrical screen becomes smaller in the heading direction of the pill material. The screw-pitch-variable hole-pitch-variable drum screen separator can enable the pill material to form the pill material flowing curtain uniform in thickness and enable the air classification effect to be better, and is favorable for obtaining clean and uniform pill material.
Description
technical field [0001] The present invention relates to a shot material separation equipment, in particular to a variable-pitch variable-hole-pitch roller sieve separation device capable of separating large particles, small particles and fine dust from shot materials to obtain clean and uniform shot materials. device. Background technique [0002] In mining equipment, metallurgical equipment, cement machinery, shot blasting equipment, sandblasting equipment and many other occasions, it is necessary to separate the large particles, small particles and fine dust in the shot to obtain clean and uniform shot. The trommel screen separator is a commonly used separation equipment at present. It conveys the pellets through the internal helical blades arranged inside the cylinder screen. During the conveying process, the pellets fall from the holes on the cylinder screen to form a flow curtain of pellets, and then The large particles, small particles and fine dust in the pellets are...
