Description

Technical Field

[0001] The utility model relates to the field of garbage treatment, in particular to a collaborative treatment system for garden garbage and kitchen waste. Background Art

[0002] With the development of society, there are more and more garden garbage and kitchen waste generated in urban life. Among them, garden garbage mainly comes from tree branches, fallen leaves, grass clippings, withered flowers and other pruning wastes generated during the process of urban greening and beautification, suburban forestry tending and fruit tree pruning operations; while kitchen waste refers to the organic-rich garbage generated by families or vegetable markets, including leftovers, rice, vegetable leaves, fruit peels, eggshells, bones, shells, etc.

[0003] At present, garden garbage and kitchen waste are both treated independently. Among them, most of the garden garbage is currently landfilled and incinerated (which causes environmental pollution and resource waste), and a small amount of garden garbage is treated by composting fermentation. However, due to the large size of tree branches and trunks in garden garbage and the presence of substances such as lignin and cellulose that are not easily degraded, the composting fermentation treatment of garden garbage has problems such as a long ripening period and low efficiency. And most of the kitchen waste is also currently landfilled and incinerated (which also causes environmental pollution and resource waste), and a small amount of kitchen waste is treated by composting fermentation.

[0004] In view of the existence of the above problems, it is necessary to study a collaborative treatment system for garden garbage and kitchen waste, which can realize the collaborative treatment of garden garbage and kitchen waste, and has the advantages of improving the recycling rate of garden garbage, reducing the use of urea, and high fertilizer production efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a collaborative treatment system for garden garbage and kitchen waste, which can realize the collaborative treatment of garden garbage and kitchen waste, and has the advantages of improving the recycling rate of garden garbage, reducing the use of urea, and high fertilizer production efficiency.

[0006] To achieve the above purpose, the solution of the utility model is:

[0007] A co - processing system for garden waste and kitchen waste, which includes a garden waste crushing device, a garden waste sorting device, a wood drying and crushing device, an RDF granulation device, a kitchen waste organic matter separation device, a mixing device, and an organic fertilizer fermentation device; the discharge end of the garden waste crushing device is connected to the feed end of the garden waste sorting device, the non - perishable material discharge end of the garden waste sorting device is connected to the feed end of the wood drying and crushing device, and the discharge end of the wood drying and crushing device is connected to the RDF granulation device; the organic matter discharge end of the kitchen waste organic matter separation device and the perishable material discharge end of the garden waste sorting device are connected to the feed end of the mixing device, and the discharge end of the mixing device is connected to the feed end of the organic fertilizer fermentation device.

[0008] The garden waste sorting device adopts an air - separation specific gravity separator.

[0009] The organic fertilizer fermentation device adopts an aerobic organic fertilizer fermentation device.

[0010] The co - processing system for garden waste and kitchen waste further includes a drying device; the discharge end of the wood drying and crushing device is connected to the RDF granulation device through the drying device.

[0011] The co - processing system for garden waste and kitchen waste further includes an RDF packaging device, and the feed end of the RDF packaging device is connected to the discharge end of the RDF granulation device.

[0012] The co - processing system for garden waste and kitchen waste further includes an organic fertilizer screening device, and the feed end of the organic fertilizer screening device is connected to the discharge end of the organic fertilizer fermentation device.

[0013] The organic fertilizer screening device adopts a drum screen.

[0014] After adopting the above - mentioned scheme, the working principle of the present utility model is as follows: The collected kitchen waste is put into the kitchen waste organic matter separation device, and the kitchen waste organic matter separation device separates the organic matter in the kitchen waste and sends it into the mixing device; while the collected garden waste is first put into the garden waste crushing device for crushing, and the crushed garden waste is sent into the garden waste sorting device for sorting. The garden waste sorting device divides the crushed garden waste into perishable materials (such as branches and leaves, turf) and non - perishable materials (such as tree trunks). The non - perishable materials are crushed by the wood drying and crushing device and then sent into the RDF granulation device for granulation to obtain biomass fuel (i.e., RDF), and the perishable materials are sent into the mixing device to be mixed with the organic matter in the kitchen waste. The mixed perishable materials and organic matter enter the organic fertilizer fermentation device for fermentation to form organic fertilizer.

[0015] As can be seen from the above, a co-processing system for garden waste and kitchen waste of the present utility model can achieve the co-processing of garden waste and kitchen waste. Among them, the co-processing system for garden waste and kitchen waste of the present utility model can jointly produce organic fertilizer from the perishable substances in garden waste and the organic matter in kitchen waste. Moreover, since the organic matter in kitchen waste is rich in nitrogen elements, there is no need to add additional nitrogen fertilizer when producing organic fertilizer, which helps to reduce costs. In addition, the co-processing system for garden waste and kitchen waste of the present utility model can separate the perishable substances and non-perishable substances in garden waste through the garden waste sorting device, so that the non-perishable substances in garden waste do not participate in the production of organic fertilizer and can improve the fertilizer production efficiency. The non-perishable substances in garden waste are granulated through the RDF granulation device to obtain biomass fuel, thereby improving the recycling rate of garden waste.
