Kitchen waste sorting and pulping method and large-substance sorting machine and fine pulper thereof

Abstract

The invention relates to a kitchen waste sorting and pulping method and a large-substance sorting machine and a fine pulper thereof. Original kitchen waste is conveyed into the large-substance sortingmachine, a sorting main shaft drives a plurality of sets of stripping conveying tools to rotate at a low speed to scatter large inert sundries in the kitchen waste and push oil-water mixtures and organic matter to the outlet direction after stripping, sorted rough slurry flows into a rough slurry temporary storage bin through a rough steel sieve screen board, the sorted inert sundries are discharged through a large material outlet, a dual-cylinder slurry conveying pump continuously conveys the rough slurry into a crushing bin of the fine pulper, a crushing main shaft drives a plurality of sets of crushing tools to rotate at a high speed, the rough slurry is cut and crushed, the crushed slurry flows into a fine slurry temporary storage bin through a fine steel sieve screen board, and lightfragments are thrown out through a fragment discharging outlet on the upper rear portion. The method can effectively separate degradation-resistant inert sundries and reduce loss of grease and organic mater, the sundry content of the slurry is low, materials are uniform, and the equipment failure rate and abrasion are reduced.

Description

technical field [0001] The invention relates to a method for sorting and pulping kitchen waste, a large material sorting machine and a fine pulping machine, and belongs to the technical field of kitchen waste treatment. Background technique [0002] The composition of food waste in my country is complex, the management of collection and transportation is not in place, and there are a lot of food waste debris, such as cutting boards, plastic buckets, large plastic bags, rubber, fabrics, metal blocks and large bones. Bulky debris mainly includes large plastic bags, metal products, bones, ceramic glass products, fabrics and rubber products. In order to ensure the smooth operation of the follow-up treatment process, it is necessary to sort out the debris that cannot be used in the follow-up process as much as possible during the pretreatment of food waste, otherwise it will cause equipment jams, increased wear, reduced purity of organic matter, and increased difficulty of subseq...

AI Technical Summary

Problems solved by technology

The traditional separation technology has the following problems: (1) The loss rate of organic matter in rough separation is high, the amount of separated materials is large and the water content is high, and the loss of oil is large

(2) The fine sorting is not thorough, there are many sundries in the slurry, and the sorted sundries have high moisture content

Due to the direct acceptance of original and complex materials and the need for crushing and sorting, the sorting speed is very high. The high-speed processing of complex materials makes the equipment failure rate and wear of the first method very high. Due to the need to ensure the processing capacity, the aperture of the screen cannot be very large. Small, so the pulping effect is not satisfactory, and the debris particles are large and the number is large

However, multi-stage sorting pulping has the problems of long process chain, many equipment, large loss of organic matter, and large loss of oil. At the same time, it faces the problem that ceramics, glass, etc. are too finely broken, which makes it difficult to separate the subsequent inert heavy sand and gravel.
