Comprehensive garbage sorting machine

Abstract

The invention relates to a comprehensive garbage sorting machine, which comprises a cylindrical shell, a feed inlet and a feed outlet. A spiral pushing device is arranged at the middle part of the shell, a plurality of holes are arranged at the bottom of the shell. An n-level exhaust inlet is arranged at the middle-upper part of the shell, wherein n is greater than 0 and smaller than 6. The spiral pushing device comprises a screw and a vane spirally and axially extending along the screw. The screw is provided with an adjustable speed reducer. Furthermore, a gap is reserved between periphery of the screw of the spiral pushing device and the inner wall of the shell. The gap must ensure that the beer bottle cannot stand. Furthermore, the exhaust strengths of the exhaust inlets are different. Preferably, the exhaust strength of the n-level exhaust inlet increases gradually. A wind shelter is arranged at the tail end of the shell. The front half part at the bottom of the shell adjacent to the feed inlet is small, and the rear half part far away from the feed inlet is great. The comprehensive garbage sorting machine effectively separates mixed domestic garbage through multiple spiral movements by adding the spiral pushing device and the multi-level exhausting device.

Description

technical field [0001] The invention relates to a garbage comprehensive sorting machine, which is used for sorting mixed household garbage. Background technique [0002] Mixed domestic waste contains plastics, bricks, bottles, soil residue and organic matter, etc. The existing waste sorting technology mainly includes six categories: (1) Screening: such as figure 1 As shown, there are several holes at the bottom of the container. After the garbage is input from the feed port, only soil residue and some organic matter are filtered from the bottom of the container, and other garbage is output from the discharge port. Obviously, this method makes the garbage at the discharge port still mixed together, which can only play a role in reducing the amount. (2) winnowing: if figure 2 As shown, the inlet of the container is equipped with a blower port, and the waste is input from the upper part of the feed port. After strong air selection, different discharge areas are formed in the...

AI Technical Summary

Problems solved by technology

(3) Magnetic separation: use the principle of magnets to sort out magnetic metals, and the sorting range is very narrow

(4) Centrifugal separation: use the principle of centrifugal force to sort out non-magnetic metal waste, and the sorting range is very narrow

This method not only wastes clean water, but also has a lot of sewage, and it is difficult to separate the dregs and organic matter in the sediment.
