Combined type vibrating screen

Abstract

The invention discloses a combined type vibrating screen. The vibrating screen comprises a screen box, a vibrating screen set, a relaxation screen set and a material guiding member, wherein the vibrating screen set comprises a plurality of vibrating screen nets, the vibrating screen nets are sequentially connected, transition parts are formed at the connecting positions, the relaxation screen set comprises a plurality of relaxation screen nets, the material guiding member comprises mounting parts and a plurality of extending parts, the mounting parts are fixed to the transition parts in the vertical direction, and the extending parts are arranged at intervals and extend away from the mounting parts. The vibrating screen set and the relaxation screen set can jointly act to achieve secondary screening of materials, the vibrating screen set of a step-shaped structure and the material guiding member can be matched with each other, the tearing and dispersing effects on the materials are effectively improved, the situation that the humid and adhesive materials are agglomerated and stay is avoided, and the screening efficiency on the viscous or humid materials is greatly improved. In addition, the screen nets in modular design is convenient to mount, dismount and overhaul, screen nets of different models or types can be rapidly replaced to be suitable for materials of different types, and the applicability of the equipment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of material screening, in particular to a composite vibrating screen. Background technique [0002] With the acceleration of urbanization, the output of urban garbage, waste, etc. continues to increase, and the increased pollution of garbage, waste, etc. to the environment is also becoming more and more serious. Screening is an important link in the solid waste treatment process, and the solid materials after screening are more beneficial to further processing. [0003] Most of the existing material screening realizes the separation of materials through the vibration of the screen, but this method is not suitable for wet or sticky materials, and sticky or wet materials are prone to stick to the screen holes or block the screen during the working process. As a result, the equipment cannot run continuously for a long time, and the screening efficiency is low. In addition, most of the current equipment adopts...

Problems solved by technology

[0003] Most of the existing material screening realizes the separation of materials through the vibration of the screen, but this method is not suitable for wet or sticky materials, and sticky or wet materials are prone to stick to the screen holes or block the screen during the working process. As a result, the equipment cannot run continuously for a long time, and the screening efficiency is low

In addition, most of the current equipment adopts an overall welded structure, which not only occupies a large area, but also needs to disassemble and replace the entire layer when the regional sieve plate is damaged, resulting in high operating costs
