Novel roller screen

Abstract

The invention discloses a novel roller screen, and belongs to the field of screening equipment. The novel roller screen comprises a frame, a screen cylinder, a motor, a speed reducer and a screen cylinder cleaning device, wherein the screen cylinder cleaning device comprises a roller, an adjusting rotating shaft, a cleaning motor and a plurality of cleaning parts; the roller is hollow and rotatably connected with the frame; the adjusting rotating shaft is rotatably connected in the roller; a plurality of rows of through holes which are uniformly distributed circumferentially are formed in theroller; the plurality of cleaning parts correspond to the plurality of through holes one by one; the distribution mode of screen holes in the screen cylinder is the same as that of the through holes in the roller; each cleaning part comprises an outer sleeve, an ejector rod, a limiting baffle plate, a spiral spring and a bottom plate; the outer sleeves, the ejector rods, the limiting baffle plates, the spiral springs and the bottom plates are positioned inside the roller; two rotary tables are arranged on the adjusting rotating shaft; a plane spiral sliding groove is formed in the end surfaceof each rotary table; a plurality of sliding blocks are arranged on the plane spiral sliding grooves; and the bottom plates are arranged on the sliding blocks. According to the the novel roller screen, the dredging strength of the screen cylinder cleaning device to the screen holes can be flexibly adjusted as required.

Description

technical field [0001] The invention relates to the field of screening equipment, in particular to a novel drum screen. Background technique [0002] Drum screen is a kind of machinery widely used in sorting technology. A trommel usually includes a frame, a screen drum, a motor and a reducer. The sieve cylinder is installed obliquely on the frame, and the motor is connected with the sieve cylinder through a reducer through a coupling to drive the sieve cylinder to rotate around its axis. When the material enters the screen cylinder, due to the inclination and rotation of the screen cylinder, the material on the screen surface turns and rolls on it, so that the qualified material (product under the screen) is discharged through the sieve hole on the screen cylinder, and the unqualified material (screened product) is discharged through the screen hole on the screen cylinder. The upper product) is discharged through the discharge port at the end of the screen drum. Due to th...
