Small kitchen garbage on-site fertilization equipment

Abstract

The invention discloses small kitchen garbage on-site fertilization equipment which adopts a vertical and three-section type design and combines one-way material conveying of vertical gravity sedimentation with transverse screw propulsion type material conveying to perform staged aerobic fermentation. The equipment is composed of a pretreatment bin, a primary fermentation bin and a secondary fermentation bin, wherein the water content of the kitchen waste is adjusted through the pretreatment bin, and hot wet steam discharged by the pretreatment bin and the primary fermentation bin is used for dynamic temperature control and water supplementing of the secondary fermentation bin; the bottleneck problem that the water content of aerobic fermentation of the kitchen garbage is too high and the limitation of the source of auxiliary materials are solved, rapid initiation of the kitchen garbage is achieved, the fertilizer quality is good, the occupied area of equipment is small, the operation energy consumption is low, and the equipment is suitable for on-site fertilization of community, village and town kitchen garbage.

Description

technical field [0001] The invention belongs to the field of resource utilization of organic waste, and in particular relates to a small-scale equipment for in-situ fertilization of kitchen waste. Background technique [0002] Kitchen waste mainly comes from food waste and residues generated in family kitchens, farmers' markets, public canteens and the catering industry. With the implementation of my country's "garbage classification" policy, the separation rate of kitchen waste has increased significantly. In addition, kitchen waste is high in protein, organic, high in water, easy to corrupt, and the cost of collection and transportation is high. The demand for local resource utilization is more urgent. . At present, the on-site treatment methods of kitchen waste mainly include crushing and direct discharge and fertilization. Among them, the kitchen waste is crushed and discharged directly, which is convenient to operate, but the crushed kitchen waste is directly discharge...

AI Technical Summary

Problems solved by technology

Among them, the kitchen waste is crushed and discharged directly, which is convenient to operate, but the crushed kitchen waste is directly discharged into the sewer, which causes a waste of resources and increases the processing load of the urban sewage treatment plant.

In-situ fertilization of kitchen waste is to convert kitchen waste into organic fertilizer through aerobic fermentation under the action of microorganisms, which can be used for landscaping or soil improvement of surrounding farmland. The cycle is long, the malodorous gas is released, and the quality of the prepared organic fertilizer is low, which is difficult to promote and apply in the market
