Preparation method for making recycled material from domestic kitchen waste

Abstract

The invention discloses a preparation method for making reused substances from domestic kitchen waste. Including acquisition of manufacturing equipment, including crusher, extrusion molding machine, blanking guide mechanism and drying mechanism, waste heat drying ember chamber, waste heat flue gas circulation pipe, opening the waste heat flue gas circulation pipe, passing hot flue gas into the forming extrusion Extruder, hot flue gas temperature 100-200°C, preheating 5-10min; forming extruder preheating 3-5min; open the heat radiation source of the drying mechanism, set the heating temperature 200-280°C, the material of the drying mechanism The transmission device is preheated for 1 to 3 minutes; domestic kitchen waste and straw powder are mixed at a ratio of 3:1 to 5:1, and 3% to 6% of modified starch is added, and then enter the crusher for crushing; after crushing, the material enters the extrusion molding machine and keeps Extrusion heat conduction for 5s, extrusion molding; extruded materials enter the drying mechanism, and the drying time of materials is controlled for 20s; the dried materials are transferred to the residual heat drying chamber, where the residual heat is used to dry and store.

Description

technical field [0001] The invention relates to the technical field of combustible domestic waste treatment, in particular to a preparation method for making reusable materials from domestic kitchen waste. Background technique [0002] At present, the per capita domestic garbage output in cities across the country is high, and the problem of garbage treatment and disposal has become one of the most urgent problems faced by my country's urban environmental sanitation. Since domestic garbage itself cannot be extruded by machines, it is usually used in the prior art. The organic waste in domestic waste is mixed with biological straw in a certain proportion for re-preparation to form reusable materials such as pellet feed, fuel or bio-fertilizer, which can not only make full use of a large amount of waste biomass in rural areas, but also solve some waste disposal problems. Improve people's living environment and reduce air pollution. The crude fiber content in biomass is high, th...

AI Technical Summary

Problems solved by technology

The crude fiber content in biomass is high, the density is lower than that of viscose fiber, and the bulk density and breaking strength are small. Since the biomass crude fiber contains a large number of voids, it is easy to be formed under pressure after being mixed with organic waste, which reduces the pressure consumption during the mixing process. The reused material after forming has high strength, uniform density, easy storage and convenient use. The existing organic waste preparation methods adopt screening, crushing, extrusion molding and natural air drying methods. The crusher used in the crushing and extrusion molding process And the forming machine only crushes and extrudes the material mixed with organic waste and straw. Due to the high moisture content in the waste, the formed material also contains more water. It takes a long time to dry by natural air drying, and the efficiency is low. Poor air-dry quality, affecting product quality and use of reused substances such as pellet feed, fuel or biofertilizer
