Embodiment 1

[0067] 1) The food waste transport truck dumps the materials into the silo, and the chain-plate conveyor at the bottom of the silo transports the materials to the roller crusher. During the conveying process, the chain-plate conveyor filters out most of the free wastewater through the plate gap; The silo is equipped with an automatic opening and closing cover. The conveying equipment under the silo adopts a chain conveyor, and the gap between the chain conveyors is 8mm. Each chain plate is equipped with a scraper baffle, and the height of the baffle is 150mm. The free wastewater filtered out by the clearance of the guide plate of the water receiving tank is set under the surface;

[0068] 2) The food and kitchen materials are roughly crushed in the double-roll crusher, and the hard-to-break impurities can be removed in it to avoid damage to the integrated machine; the double-roll crusher is provided with an inspection port to facilitate the cleaning of unbreakable impurities, a...

Abstract

The invention provides a kitchen waste anaerobic pretreatment device and method. The device comprises a crusher, a crushing and screening all-in-one machine and a sand remover. The crusher is provided with a kitchen waste inlet and a crushed material outlet. The crushing and screening all-in-one machine is provided with a crushed material inlet, a kitchen waste serous fluid outlet and an impurity outlet. The crushed material inlet is connected with the crushed material outlet. The sand remover is provided with a kitchen waste serous fluid inlet. The kitchen waste serous fluid inlet is connected with the kitchen waste serous fluid outlet. Through the device provided by the invention, components such as plastic bags, dump rags, bottles, tableware and gravels which cannot be subjected to anaerobic fermentation conveniently in kitchen waste can be filtered out as much as possible, the material solid content and material particle diameter are adjusted, the subsequent anaerobic process requirement of the kitchen waste is met, and thus the anaerobic treatment effect can be improved. In addition, the kitchen waste is subjected to anaerobic pretreatment through the device, process equipment is simple and reliable, and the device is quite suitable for mass application.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to an anaerobic pretreatment device and method for kitchen waste. Background technique [0002] Food waste is the most important type of municipal organic waste, including food processing waste and food residues generated by families, schools, canteens and catering industries. In China, due to the improvement of living standards and the existence of bad eating concepts, people gather in restaurants not only in terms of quality but also in quantity, and at least 30% of the space must be reserved in terms of quantity. The ubiquity of these phenomena has caused an astonishing amount of food waste such as leftovers in some canteens, hotels, restaurants and other eating units. [0003] Anaerobic treatment of food waste (anaerobic fermentation to produce biogas) is a new technology, and its application in Europe is relatively mature. However, my country adopts anaerobic ...
