Description

Dispersed winnowing machine feed hopper

Technical Field

The utility model relates to the field of winnowing machines, in particular to a dispersed winnowing machine feed hopper.

Background

In the development process of modern cities, the generation of various solid waste garbage is inevitable, and a better treatment method is found under the high requirement of advocating sustainable cycle reproduction, so that the new requirement on the industrialized route is met.

With the improvement of living standard, various wastes in daily life are increased, and usually include recyclable materials, such as plastic bags, metal bottle caps, packaging paper boxes and the like. If the domestic garbage is not screened, the domestic garbage cannot be effectively treated by any method, and obviously, the finer the screening of the domestic garbage is, the higher the recycling degree of renewable substances from the domestic garbage is.

The refining screening of the domestic garbage currently adopts two measures: firstly, a plurality of garbage recycling bins are arranged in a town community, people are required to put household garbage in a classified mode, the method is waited for the improvement of the overall environmental awareness of social personnel, and the pushing difficulty is large; secondly, before the domestic garbage is deeply treated, the domestic garbage is sorted manually, so that the labor intensity is high, the production environment is severe, and the domestic garbage is difficult to thoroughly sort.

Winnowing machines have gradually become the basic equipment for processing kitchen waste, construction waste and other light and heavy material sorting procedures in other fields. For example, CN1026586108A discloses a garbage winnowing device, which works as follows: garbage is crushed and input into a feeding opening, a fan directly blows air towards an air separation cylinder, and high-pressure air pressure forms negative pressure in the feeding opening so that the garbage is blown into a separation cylinder through a jet principle. The wind pressure of the wind power generation device rotates spirally in the winnowing cylinder along with the wind guide belt to form spirally rotating airflow. The garbage rotates in the spiral rotating airflow generated in the sorting cylinder along with wind power, and the garbage rotates fast at the lower part of the cylinder wall and slowly at the upper part of the cylinder wall when being formed by self gravity. When the garbage is transferred to the wall of each spiral stage, the rotating speed is reduced from bottom to top, and the non-plastic films with different specific gravities in the garbage respectively fall into the slag discharging port on the lower wall part by means of self weight in each spiral stage air guide belt and are output to the slag collecting chamber. After multi-stage rotation, the plastic film is gradually separated from the mixed garbage and is output to a material collecting bin from an output port at the rear end of the air separation cylinder.

The winnowing is a direct feeding mode for feeding the winnowing machine, and the winnowing machine has the defect that the winnowing efficiency is low because materials are not dispersed. The other feeding mode is a common vibration feeder, and the defect of the vibration feeding mode is that the equipment space is large.
