A food waste sorting line

Abstract

A trommel screen and its food waste sorting line, the food waste sorting line includes: a hopper, used to store garbage to be processed, and continuously input the garbage into a crusher; a crusher, used to break the garbage into granules shape, and then enter the roller sieve for screening: the roller sieve is used to screen larger volumes of garbage, and the screened small particles of garbage are fed into the drum sieve; the drum sieve is used to further screen the garbage so that the small particles of garbage It is screened out and then sent to the crusher; the grinder is used to grind the garbage into a slurry-like liquid mixture, and then transport the ground garbage to the solid-liquid separator; the solid-liquid separator is used to grind the slurry Solid-liquid separation of waste. In this embodiment, a screw extruder can be used to separate the solid and liquid of the pulpy garbage. Of course, the liquid can be purified after fermentation, so as to be recycled to save water resources. Solids are generally used as raw materials for fertilizers and processed into fertilizers.

Description

technical field [0001] The invention relates to a kitchen waste treatment technology, in particular to a kitchen waste sorting line. Background technique [0002] Garbage sorting is currently the main means of environmental protection. The treatment of kitchen waste mainly includes the following processes: collection, crushing, screening, grinding, fermentation, and finally extraction of industrial crude oil, industrial alcohol, and industrial protein. In the actual implementation process, due to the lack of residents' awareness of waste classification, food waste is easily mixed with other waste, such as tableware, bones, metal utensils, plastic products, etc., which brings great difficulties to the subsequent treatment of food waste. serious impact. First of all, when screening, since trommel screens, roller screens, and vibrating screens are mostly used for screening, it is easy to cause blockage and seriously affect the stability of the equipment. Secondly, in order to...

Problems solved by technology

In the actual implementation process, due to the lack of residents' awareness of waste classification, food waste is easily mixed with other waste, such as tableware, bones, metal utensils, plastic products, etc., which brings great difficulties to the subsequent treatment of food waste. severe impact

First of all, when screening, since trommel screens, roller screens, vibrating screens, etc. are mostly used for screening, it is easy to cause blockage and seriously affect the stability of the equipment.

Secondly, in order to avoid high-frequency blockage during screening, generally the particles screened are relatively large, which makes it easy to mix in harder glass slag, ceramic slag, metal slag, plastic slag, etc., causing greater damage to the subsequent grinder. burden, and it is easy to cause damage to the blade of the grinder and blockage inside the grinder, so the failure rate of the grinder is abnormally high. At present, the above-mentioned problems are mainly reduced by increasing the size of the particles ground by the grinder, but This causes problems such as long subsequent fermentation time and incompleteness, which seriously affects the treatment and recycling of kitchen waste.
