Automatic separating device and method for domestic garbage

Abstract

The invention discloses an automatic separating device and an automatic separating method for domestic garbage, and belongs to the technical field of garbage separation. The separating device has a differential crawler reciprocating structure, and comprises an upper crawler system consisting of an upper chain wheel, an upper chain wheel, an upper chain group and an upper harrow mechanism, a lowercrawler system consisting of a lower chain wheel, a lower chain group, a lower chain wheel and a lower harrow mechanism, a discharging system consisting of a strainer, a shaking-off mechanism, a first-level discharge hole, a second-level discharge hole and a third-level discharge hole, a feeding hole, a frame and a motor driving system. In the method, the continuous conveying of the materials is realized through the crawler harrow mechanism, the bag-breaking and crushing treatment on the materials is realized through the relative tearing force generated by the upper and lower harrow mechanisms, and the separation of the materials is realized through the sieving and shaking-off mechanisms, so three functions of conveying, bag-breaking/crushing and separating the materials are integrated and the domestic garbage is separated into three classes, namely heavy small-sized garbage, heavy large-sized garbage and light large-sized garbage. The device and the method have the advantages of highseparation efficiency, large treatment capacity, low energy consumption and environmental friendliness.

Description

Technical field [0001] The invention belongs to the technical field of garbage sorting, and in particular relates to an automatic sorting equipment and method for household garbage, which is suitable for automatic sorting of urban household garbage. Background technique [0002] In the field of municipal solid waste treatment, the problems of relatively lagging facilities construction and low level of resource utilization are more prominent. As the amount of municipal solid waste continues to rise and its composition becomes more and more complex, how to achieve “reduction, resource utilization, and harmless” treatment of waste has become a very urgent topic. Due to the influence of people's living habits, regional differences, seasonal changes and other factors, the composition, scale and composition of urban domestic garbage in our country are very different, which increases the difficulty of "three transformations" of garbage. The comprehensive garbage disposal method has bec...

Problems solved by technology

Although these two methods can achieve rough separation of garbage, there are obvious shortcomings: the winnowing system has large resistance, relatively high energy consumption, low sorting efficiency, and secondary dust removal is required, which is prone to secondary environmental pollution; The screening is mainly based on the drum screen, and the garbage is entangled in the drum so that the sorting is not thorough and the efficiency is low

However, since the first stage of so
