Grinding mill and kitchen waste sorting assembly line

Abstract

The invention discloses a grinding mill and a kitchen waste sorting assembly line. The kitchen waste sorting assembly line comprises a hopper, a crusher, a roller screen, a drum screen, a grinding machine and a solid-liquid separator, wherein the hopper is used for storing to-be-treated waste and continuously inputting the waste into the crusher; the crusher is used for crushing waste into particles and then inputting the particles into the roller screen for screening; the roller screen is used for screening large-size waste and inputting screened small-particle waste into the drum screen. thedrum screen is used for further screening waste, so that small-particle waste is screened out and then fed into the crusher; the grinding machine is used for grinding the waste into a slurry liquid mixture and then conveying the ground waste to the solid-liquid separator; and the solid-liquid separator is used for carrying out solid-liquid separation on the slurry waste. According to the kitchenwaste sorting assembly line, a screw extruder can be adopted, so that solid and liquid of the slurry waste can be separated out; certainly, the liquid can be purified after being fermented, so that the liquid can be recycled to save water resources; and solid generally serves as a fertilizer raw material to be processed into fertilizer.

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.
