Household waste classifying device

Abstract

The invention relates to a household waste classifying device which comprises a machine body, wherein a crushing cavity and a separating cavity are formed in the machine body up and down separately and communicate with each other; a crushing device is arranged in the crushing cavity; a separating device is arranged in the separating cavity; the crushing device comprises a plurality of steel kniferolling shafts and a plurality of rubber rolling shafts corresponding to the steel knife rolling shafts; and a plurality of high-pressure water sprayers are arranged in the crushing cavity and flush the corresponding steel knife rolling shafts and / or rubber rolling shafts in central symmetry distribution. The household waste classifying device can quickly, simply, conveniently and effectively classify household waste, is different from the existing classifying standard and method, realizes classification according to weight, hydrophilia, density and other features of waste after the preliminary crushing of waste, is simple, high in integration level and convenient to operate, and can ensure the sorting effect to certain degree.

Description

technical field [0001] The invention relates to a sorting device for domestic garbage, which belongs to the field of environmental protection equipment. Background technique [0002] Most domestic garbage can be classified into fruit shell garbage, larger particles or metal garbage, soft sediment garbage that can absorb water and settle, and floating garbage with low density; in real life, due to various reasons, my country The classification of waste in the residential stage is slow. The above-mentioned domestic waste is generally not classified, but waste classification is urgent in our country. According to reports, Beijing or Shanghai produces nearly 25,000 tons of waste a day, most of which are domestic waste, which cannot be classified and recycled. All of them need to be landfilled, which will cause great damage to the environment, and garbage sorting and recycling are imminent. In addition, garbage sorting also contains huge economic benefits.

[0002] Most of domestic garbage can be classified into fruit shell garbage, larger particles or metal garbage, soft sediment garbage that can absorb water and precipitate, and floating garbage with low density; in real life, due to various reasons, my country's current The classification of garbage in my country is slow in the residential stage. The above-mentioned household garbage is generally not classified, but garbage classification is an urgent task in our country. According to reports, Beijing or Shanghai produces nearly 25,000 tons of garbage a day, most of which are household garbage, and garbage cannot be sorted and recycled. All of them need to be landfilled, which will cause great damage to the environment, and garbage sorting and recycling are imminent. In addition, garbage sorting also contains huge economic benefits. The research and development of domestic waste sorting devices has broad market prospects. At present, most of the garbage recycling on the market is still Manual sorting is used, partly with equipment sorting, but the sorting equipment is large in size, cumbersome in process, high in equipment cost, inconvenient in operation and low in efficiency
