Screening equipment and method for screening out solid waste long materials

Abstract

The invention discloses screening equipment and method for screening out solid waste long materials. The screening equipment comprises at least two sliding rods capable of rotating around respective corresponding fulcrums, and elastic elements. A screening falling channel is formed between every two adjacent sliding rods; When waste is fed into the sliding rods, the portions, bearing the waste, ofthe sliding rods rotate downwards around the fulcrums and are in an inclined state all the time. The elastic elements are arranged on the rotating paths of the sliding rods and provide elastic deformation for the sliding rods. The screening method is used for screening through the equipment. The screening equipment and method are high in screening efficiency and high in working efficiency.

Description

technical field [0001] The invention relates to the field of solid waste screening, in particular to a screening device and method for screening long solid waste materials. Background technique [0002] Generally, solid waste can meet the requirements after being coarsely crushed by a double-shaft crusher and finely crushed by a single-shaft crusher. However, after the solid waste is crushed by the twin-shaft crusher, there will still be a small amount of filament and thread-shaped materials, which will affect the subsequent uniform batching and pneumatic conveying feeder. Therefore, these filaments need to be crushed , Silk-shaped materials are sorted out and then returned to the crushing link. [0003] Existing screening methods generally use screening equipment with a screen structure to sieve qualified waste from the screen holes by trembling, and the waste remaining on the screen is the required filament and silk-shaped material. However, screening equipment with this...

[0002] Generally, solid waste can meet the requirements after being coarsely crushed by a double-shaft crusher and finely crushed by a single-shaft crusher. However, after the solid waste is crushed by the twin-shaft crusher, there will still be a small amount of filament and thread-shaped materials, which will affect the subsequent uniform batching and pneumatic conveying feeder. Therefore, these filaments need to be crushed , silk-shaped materials are sorted out and then returned to the crushing link

[0003] Existing screening methods generally use screening equipment with a screen structure to sieve qualified waste from the screen holes by trembling, and the waste remaining on the screen is the required filament and silk-shaped material. However, screening equipment with this type of screen structure has problems such as low screening efficiency and low work efficiency during use. The material will block the sieve holes, so that the waste materials that should pass through the sieve holes cannot be sieved. Moreover, the waste that has not been sieved remains on the screen, which is easy to accumulate, and needs to be cleaned out manually at regular intervals, and there is a certain degree of difficulty in cleaning the filaments and silk-shaped materials that are entangled on the screen, and some auxiliary equipment needs to be configured. Cleanup, cumbersome and inefficient
