Abstract

The invention relates to a swinging type screening device for screening cylindrical solid materials. The winging type screening device comprises a pair of horizontally-arranged groove-shaped rails, a rectangular frame type main body, and screen plates installed in a frame of the main body and arranged in parallel, wherein the internal bottom surfaces of the groove-shaped rails are concave-convex; rollers are arranged at four corners on one lower end surface of the frame type main body respectively and move in the rails; the screen plates comprise rectangular screen plate frames installed on the frame of the main body and parallel screen strips arranged on the screen plate frames, the axial directions of the screen strips on each layer of the screen plate are the same, and the distance between two of the screen strips is 5.55mm to 32.3mm, and the distance between the screen strips is reduced sequentially from the uppermost layer of screen plate to the lowermost layer of screen plate. The swinging vibration type screening device further comprises a driver, wherein the driver drives the rectangular frame type main body to swing in a reciprocating manner and vibrate through a connecting rod connected with the frame type main body. The screen plates can be arranged horizontally or obliquely. The cross section shapes of the screen strips and the distances among the screen strips determine the screening efficiency and the screening effect of cylindrical solids. And the winging type screening device has the characteristics of simple structure, low manufacturing and operating costs, high pertinence, energy conservation and high efficiency.

Description

technical field [0001] The invention relates to a screening device, in particular to a swing type screening device for screening solid columnar materials. Background technique [0002] Regarding the recycling status of waste batteries in our country, it is not optimistic and there are many problems. In 1998, my country's battery production was 14 billion. In 2002, it reached more than 20 billion, accounting for more than 1 / 3 of the world's total battery production. It is the world's largest battery producer, but the current recovery rate of waste batteries in my country is less than 2 %. Civilian batteries are currently the most widely used and scattered battery products, with an annual domestic consumption of 8 billion. Not only mercury in the battery will cause pollution, but zinc, manganese, cadmium, lead, etc. will seep into the ground with domestic garbage, and if they exceed a certain limit, they will also cause pollution. These harmful substances enter the human bod...
