Rotary screen capable of rotating forwards and backwards and provided with spiral screening rings

Abstract

The invention provides a rotary screen capable of rotating forwards and backwards and provided with spiral screening rings, and belongs to the field of screening equipment. The defects that according to an existing rotary screen, screening efficiency is low, the screening effect is poor, and a screen net is prone to be blocked are overcome. The rotary screen is composed of a rack, a motor, four rolling wheels and a screen body, wherein the motor, the four rolling wheels and the screen body are installed on the rack, the left of the rack is higher than the right of the rack, the motor is connected with one rolling wheel, the screen body comprises two rollers, weft-direction screening strips parallel with the screen body in direction and the spiral warp-direction screening rings with screening holes in ring bodies, one roller is borne on every two rolling wheels, and the weft-direction screening strips penetrate through the screening holes in the warp-direction screening rings to form the screen. In this way, screening efficiency is improved, the screening effect is optimized, and a screen net is prevented from being blocked.

Description

technical field [0001] A drum screen with a spiral screen ring capable of forward and reverse rotation of the present invention belongs to the field of screening equipment, and in particular relates to a drum screen with a spiral screen ring capable of forward and reverse rotation. Background technique [0002] The trommel screen is a relatively traditional screening equipment. After the material of the pulverizer enters the trommel screen, it relies on the centrifugal force of the rotation of the central drum and the jigging effect to screen the material evenly, and screens the materials one by one by relying on screens of different meshes. However, during the screening process, since the sieve body always rotates in the same direction, the material is easy to accumulate on the screen, the screening efficiency is low, and the mesh is easy to be blocked. At the same time, the material is not sieved clean and wasted. It is one piece, and it is difficult to repair, so sometime...

[0002] The trommel screen is a relatively traditional screening equipment. After the material of the pulverizer enters the trommel screen, it relies on the centrifugal force of the rotation of the central drum and the jigging effect to screen the material evenly, and screens the materials one by one by relying on screens of different meshes. However, during the screening process, since the sieve body always rotates in the same direction, the material is easy to accumulate on the screen, the screening efficiency is low, and the mesh is easy to be blocked. At the same time, the material is not sieved clean and wasted. It is one piece, and it is difficult to repair, so sometimes even the entire screen needs to be replaced, which is time-consuming and labor-intensive to repair
