Embodiment 1

[0050] Such as figure 1 As shown, the food waste mechanical pretreatment system proposed in this embodiment includes: a temporary storage silo 1, a double shaftless screw conveyor 2, a vertical shaft hammer mill 3, a dust remover 4, and a homogeneous buffer box 5. And sand removal and oil separation machine 6.

[0051] Such as figure 2 , image 3 with Figure 4 As shown, the temporary storage bin 1 is provided with a feed port 11 above the feed port 11 of the temporary storage bin 1 is covered with a reversible cover 12, the reversible cover 12 is in the normally open state, and the reversible cover 12 is driven by a large cylinder 13 to turn over. The feed inlet 11 of the temporary storage bin 1 is provided with a reversible grid 14 driven by a small cylinder 15, such as Figure 4 As shown, the grid size of the reversible grille 14 is 300×300mm, and the reversing state of the reversible grille 14 is as follows Figure 5 Shown.

[0052] Such as figure 2 , image 3 with Figure 4...

Abstract

The invention discloses a kitchen waste mechanical pretreatment system and a pretreatment process for the kitchen waste mechanical pretreatment system. The mechanical pretreatment system comprises a temporary storage material bin, double non-shaft screw conveyors, a vertical shaft hammer type grinding machine, an impurity removal machine, a homogenizing cache box and a sand removal and oil separation integrated machine. By means of the kitchen waste mechanical pretreatment system and the pretreatment process for the kitchen waste mechanical pretreatment system, kitchen waste with complex composition is taken as raw materials, high-purity organic slurry is produced, aftertreatment material inlet requirements for dry or wet anaerobic fermentation or black gadfly breeding and the like are met, sorted residue meets various heat treatment technology material inlet heat value requirements for incineration, gasification and the like, separation and purification of the kitchen waste are realized, the technical bottleneck of existing kitchen waste mechanical pretreatment being long in process chain, low in organic matter separation efficiency and high in impurity content and energy consumption is broken through, and a more optimized, more suitable and more reliable mechanical pretreatment technology is provided for a city classified kitchen waste treatment project.

Description

Technical field [0001] The invention relates to the technical field of pre-treatment (pre-treatment) of kitchen waste wet anaerobic biogas production engineering, and pre-treatment (pre-treatment) engineering of kitchen waste breeding black water horsefly extraction bio-protein engineering, in particular to a mechanical pre-treatment system for kitchen waste Pretreatment process. Background technique [0002] Food waste is the most important sort of waste in the waste sorting system. It includes food processing leftovers (kitchen waste) and edible residues (sweat feet) produced by households, schools, canteens, and catering industries. Its composition is complicated, mainly A mixture of oil, water, fruit peels, vegetables, rice noodles, fish, meat, bones, waste tableware, plastics, paper towels and other substances has significant harm and duality of resources. Food waste cannot be used directly as a resource. It must undergo appropriate pretreatment technology to remove all kin...
