Description
Technical Field
The invention relates to the field of garbage treatment, in particular to a method for efficiently and microbially degrading kitchen garbage.
Background
Everyone throws away a lot of rubbish every day, and in some areas that refuse management is better, most rubbish can get innoxious processing such as sanitary landfill, burning, compost, and the rubbish in more places is often simply piled up or buried, leads to the spread of foul smell, and pollutes soil and groundwater. The cost of harmless treatment of garbage is very high, and the cost of treating one ton of garbage is about one hundred yuan to several hundred yuan according to different treatment modes. People consume a large amount of resources, produce the garbage in a large scale, consume the garbage in a large amount, and produce the garbage in a large amount. In order to bypass waste disposal, methods of sorting waste have been pursued in many cities at the present time by utilizing the existing production capacity and recycling the recycled waste, including material utilization and energy utilization, and landfill disposal of the waste which has been temporarily unavailable.
The garbage classification refers to a general term of a series of activities for storing, throwing and carrying garbage classified according to a certain rule or standard, thereby converting the garbage into a common resource. The garbage classification can improve the resource value and the economic value of the garbage, and is performed by combining the resource utilization and the treatment mode of local garbage according to the component composition and the generation amount of the garbage.
The garbage classification is an improvement of the traditional garbage collection and disposal mode, and is a scientific management method for effectively disposing garbage. The garbage classified collection can reduce the garbage treatment amount and treatment equipment, reduce the treatment cost, reduce the consumption of land resources and has social, economic and ecological benefits. After the garbage classification treatment, one of the organic garbage from kitchen garbage includes leftovers, leaves, pericarps, eggshells, tea leaves, bones, shells, etc., which generally refer to raw materials and finished products (cooked food) or residues required in the household diet.
Because the kitchen waste contains a large amount of water (the highest water content of the kitchen waste is more than 85%), the treatment of the existing kitchen waste becomes a difficult problem, and the incinerator is used for incineration, so that the temperature of the incinerator is reduced, and the service life of the incinerator is reduced; if buried, the organic matter can be decomposed by microorganisms in the nature, but if the organic matter is not sterilized rapidly or is disposed properly, the organic matter is still easy to decay and smell, and vectors such as mosquitoes, flies, insects, cockroaches and the like are bred; the kitchen waste can not be effectively treated, and the environment can be polluted, so that the health of surrounding residents is influenced.

Through the effect of torsional spring 206 and stirring piece 203 for stirring tooth 204 produces the shake of certain extent when constantly stirring the rubbish from cooking of fermenting case 1 bottom, makes the rubbish from cooking disperse, effectively improves the mixed degree of rubbish from cooking and degradation fungus, improves the degree of consistency of mixture.
Referring to fig. 6, a plurality of material distributing pieces 205 are fixedly connected to the outer ends of the material turning teeth 204, and the outer ends of the material distributing pieces 205 are triangular. When the material turning teeth 204 continuously turn over the kitchen waste, the material distributing sheets 205 disperse the caked kitchen waste, so that the resistance of the material turning teeth 204 is effectively reduced in the turning process of the material turning teeth 204, the service life of the material turning teeth 204 is prolonged, 1, the kitchen waste is effectively dispersed, and the kitchen waste is convenient to degrade.
Referring to fig. 3, a feed hopper 101 communicated with the upper end of the fermentation box 1 is fixedly connected to the upper end of the fermentation box 1, a drain pipe 102 communicated with the left end of the fermentation box 1 is fixedly connected to the left end of the fermentation box 1, the drain pipe 102 is located at the lower side of the material turning assembly 2, a control panel 3 is installed at the front end of the fermentation box 1, and the control panel 3 is in signal connection with a material turning motor 201. Control fermentation case 1 through control panel 3 for stirring subassembly 2 is regularly started and is closed, effectively improves the degree of automation to kitchen garbage processing, reduces intensity of labour.
The use principle is as follows: controlling 201 the starting time interval and the working time of the stirring motor by using the control panel 3, and controlling the liquid discharge time of the liquid discharge pipe 102 by using the control panel 3; 201 stirring motor drives stirring rod 202 and rotates, makes stirring tooth 204 constantly overturn through stirring piece 203, will be located the garbage that is in of fermenting case 1 bottom and turn up, when stirring tooth 204 produces the upset, divide material piece 205 to be in the rubbish of caking and separate, stirring tooth 204 receives torsional spring 206 effect at the removal in-process, can shake after being in rubbish production change for kitchen garbage scattering, effectively improve the mixed degree of kitchen garbage and degradation fungus, improve the degradation efficiency of kitchen garbage.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
