Embodiment Construction

[0010] Use water as the power to flush the garbage into the channel. A group of tearing machines are installed in the channel to tear the bagged garbage, and then send it to the floating sedimentation separation tank. The material with a density greater than water enters the primary sedimentation tank from the lower part of the floating sedimentation separation tank. . Adjust the flow rate of the water in the settling tank so that metals, glass, and stones with higher density and faster settling speed are separated and enter the suspension separation tank, while the rest enter the secondary settling tank. Adjust the upward flow rate of the suspension separation tank, so that the substances with different densities are gradually suspended in the water and separated, and a small amount of sundries such as peels and vegetable chips are sent to the sedimentation tank. The peels and vegetable chips separated in the secondary sedimentation tank are sent to the sedimentation tank, an...

Abstract

The invention relates to a garbage sorting and recycling method. The method is characterized by comprising the following steps: flushing garbage into a channel by water, tearing the garbage bags by a set of tearing machines arranged in the channel, separating the garbage by a floating-precipitating method so as to separate the substances with a density larger than that of water and the substances with a density smaller than that of water; for the substances with a density larger than that of water, taking water as the flowing carrier, adopting a multi-stage settling method and a suspension separating method so as to separate metals, glass, stones, and plastic in a settling tank and a suspension separating tank, delivering the residual substances to a biogas digester to carry out fermentation; for the substances with a density smaller than that of water, subjecting the substances to dehydration and baking, the separating foams, films, paper, and fibers through a winnowing method, delivering the residual substances to a fermentation chamber to carry out fermentation, then filtering to remove plastic, and finally delivering the substances to a precipitating tank.

Description

technical field [0001] The invention relates to a garbage sorting and recycling method, in particular to a sorting and recycling method combining wet type, sedimentation and winnowing. Background technique [0002] Garbage sorting methods generally go through crushing, screening, sorting, magnetic separation, and then fermentation. Due to the particularity of the garbage components, this treatment method is suitable for mineral processing, but it is inefficient for garbage. Contents of the invention [0003] The object of the present invention is to provide a garbage disposal method with high sorting efficiency. [0004] The scheme that realizes the object of the present invention is: [0005] Water is used as the power to flush the garbage into the channel, and a set of tearing machines are installed in the channel to tear the bagged garbage, and then separate by floating sedimentation method, and use water to separate the substances in the garbage with a density greate...
