Screening machine and screening device of screening machine

Abstract

The invention discloses a screening device used for screening and separating mixed materials. The screening device comprises a screening body, a driving mechanism which drives the screening body to move, and supports which support the screening body. The screening body comprises a screening mesh plate, a plurality of strip-shaped protrusions are arranged on the working surface of the screening mesh plate, and the protrusions divide the screening mesh plate into a plurality of screening regions in the length direction. The supports comprise the first support and the second support lower than the first support, wherein the first support and the second support are distributed in the length direction and connected to the ends of the screening body. The screening device is simple in structure, three types of materials can be screened and separated at the same time, the screening process can be effectively shortened, occupied work space is reduced, screening efficiency and screening quality are improved, and energy consumption is remarkably reduced. On this basis, the invention further provides a screening machine with the screening device.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to a screening machine and a screening device thereof. Background technique [0002] During garbage disposal and mineral separation, it is necessary to use a screening machine to classify and screen mixed garbage or minerals. In particular, in the screening and processing of municipal waste, due to the complex composition of domestic waste and the uneven degree of dryness and humidity, accurate and fast classification is still one of the important issues in the waste screening and processing industry today. [0003] Usually, in the screening process of garbage, the garbage is mainly divided into three categories: one is light garbage, which generally refers to plastics and other relatively light substances, etc., according to the specific composition of garbage to distinguish the classification of light garbage Types; the second is small granular substances, generally r...

AI Technical Summary

Problems solved by technology

[0005] When the screening equipment of the prior art is used for garbage classification treatment, the garbage to be screened is sorted one by one, the required process is long, and there are many related classification treatment devices and complex installation work is required

Obviously, the current screening equipment occupies a large space and consumes a lot of energy during the operation process. Moreover, when it is necessary to screen garbage from different locations, the transfer of the equipment is cumbersome.

[0006] In addition, when screening and processing light waste, due to the accumulation of waste, some light waste is accompanied by other impurities such as soil, and cannot be completely separated; moreover, the purity of light waste obtained only through the air separation device is low , garbage that may be mixed with other impurities

Therefore, the garbage screening process in the current technology cannot accurately and effectively classify the garbage.
