Description

Technical Field

[0001] The utility model relates to the technical field of garbage screening, in particular to a screening processing device applied to residues after incineration of domestic garbage. Background Art

[0002] With the increasing demand for domestic waste treatment, it is very important to effectively screen the residue after incineration. Screening the waste residue through a screening device can achieve resource recycling, reduce environmental pollution, and also help reduce the cost of waste treatment.

[0003] The residue after the incineration of domestic waste enters the screening treatment device through the feeding system. In the screening system, the residues of different particle sizes are separated into different levels under the action of the screen. The residues of smaller particle sizes fall through the sieve holes, and the residues of larger particle sizes remain on the screen surface. After screening by the screen, the residues are divided into multiple particle size levels. Finally, the residues of different particle size levels are transported to the collection system for collection through the conveying system.

[0004] The existing screening and processing device screens the garbage residue by the vibration of the screening plate, but the residue after the incineration of domestic waste has strong adhesion. They will move on the screening plate in the form of large blocks and cannot effectively pass through the sieve holes, thereby reducing the screening efficiency. Therefore, a screening and processing device applied to the residue after the incineration of domestic waste is proposed to solve the above problem. Utility Model Content
