Abstract
The present invention relates to a method for converting urban house refuse into composite fertilizer and its installation. Said invented method includes the following procedures: rough selection, sorting, magnetic separation, fermentation, stoving, pulverizing, mixing and granulation, and the invented installation includes the following equipments: conveyer, sorting device, magnetic rotating plate, fermentation tank, baker, stirring machine and granulator. Said invention can implement classification treatment and digestion of urban house refuse, and can reduce environmental pollution.
Description
The present invention relates to a kind of rubbish is converted into organic method and device, be specifically related to a kind of method and device that domestic waste is converted into compoiste fertilizer.
At present, China's garbage treatment all adopts traditional filling type method, though seem to invest little, processing power is big, still has its fatal drawback.First area occupied is bigger, moreover because the interior organism of landfill material at multiple microbial process, can produce the gas release thing by the effect of pressing several stages such as oxygen, liquefaction, generation methane, comprising a large amount of CO
2, CH
4With the volatile organic matter of other microcomponent, discharge towards periphery by landfill tectum or sidewall, underground water source is polluted, also can work the mischief to human beings'health and environment.Existing people adopts the treatment process of " burning ", though high temperature is harmless, its energy can be used for generating, is not easy to cause for the second time and pollutes, and the equipment that this kind method is adopted is relatively more expensive, and investment is big, also can cause the waste of many useful resources.The present composite fertilizer of China output is very limited, composite fertilizer's amount of application only accounts for 7.7% of total amount of application, far below level of developed countries, the composite fertilizer of quite a few need be from external import, greatly develop composite fertilizer and be the trend of the times of China's chemical fertilizer industry, municipal wastes is handled by scientific and rational processing method, turn waste into wealth, comprehensive utilization makes it to become the starting material of production composite fertilizer, and the development that promotes composite fertilizer has become a present big problem.
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of method and device that domestic waste is converted into composite fertilizer through art breading is provided.
The objective of the invention is to realize that by following technical scheme it is made up of the following step:
1〉roughly select: the foreign material that will have no benefit with artificial or mechanical system are removed;
2〉letter sorting: rubbish is carried out the branch level sortation by the eccentric wheel double vibrations;
3〉magnetic separation: metal sundries is separated with organic waste by magnetic rotary disk;
4〉ferment: organic waste is delivered to fermented 3～5 days in the fermentation vat;
5〉oven dry: the organic waste after will fermenting is sent into the baker inner drying;
6〉pulverize: the exsiccant organic waste is crushed into tiny particle;
7〉stir: in the rubbish of having pulverized, add trace element;
8〉system particle: will contain trace element and the organic waste pulverized make compound fertilizer granules.
The present invention adopts conveying belt, sorting equipment, magnetic rotary disk, fermentation vat, dryer, stirrer, system granulator to finish above-mentioned series of processes; sorting equipment adopts eccentric vibrating screen layering setting; vibratory screening apparatus mesh diameter dwindles from top to bottom gradually, connects with conveying belt between each device.
The present invention classifies domestic waste and handles and digestion, be converted into the needed composite fertilizer of China's chemical fertilizer industry, not only realized the purpose that turns waste into wealth, and make municipal wastes receipts fortune and processing accomplish rationalization, innoxious and resource utilization, to doing urban environmental hygiene well, guarantee the city cleaning, reduce environmental pollution, ensure human beings'health, have great realistic significance, can promote the use of in each large, medium and small city.
Description of drawings:
Fig. 1 is a process flow sheet of the present invention;
Fig. 2 is apparatus of the present invention synoptic diagram.
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention finishes through the following steps:
1〉roughly select: earlier rubbish is inserted above the conveying belt, roughly select with artificial or mechanical system, conveying belt speed is per hour 0.5～1.2 meter, bigger unwanted waste can be selected;
2〉letter sorting: can divide three phases to carry out, adopt eccentric vibrating screen to carry out, can large and small different materials classification be handled by the width of mesh classification of vibration screen;
3〉magnetic separation: behind three level sortations, thin material falls on the conveying belt, adorns a magnetic rotary disk in conveying belt, can be with metal species rubbish (as bottle cap etc.) absorption by the electro-magnet effect, rotating disk after rotating to another place disconnects electric current, and metal species rubbish is separated with organic matter rubbish;
4〉fermentation: be sent to fermenting tank for fermentation through the rubbish after letter sorting, the magnetic separation by conveying belt, about 35～45 cubic metres of fermentation vat volume, fermentation time is 3～5 days;
5〉oven dry: the rubbish after will fermenting is sent into oven dry in the baker;
6〉pulverize: the rubbish after will drying is sent into crushing system by conveying belt again, makes it become tiny particle;
7〉stir: earlier the organic waste after pulverizing is measured, added some trace element according to measurement result then, make it reach the standard content of composite fertilizer, stir with stirrer again;
8〉system particle: will contain trace element and the pulverizing grain of the standard composite fertilizer that stirred is inserted in the system granulator, and make compound fertilizer granules, packing is made product again.
The present invention realizes that by a series of devices as shown in Figure 2 it comprises conveying belt 1,3; 4,7,9; sorting equipment 2, magnetic rotary disk 14, fermentation vat 5; baker 8, pulverizer 10, stirrer 11; system granulator 12, sorting equipment 2 adopts eccentric vibrating screen 13 layering settings, can be provided with three layers; every layer of vibratory screening apparatus mesh diameter dwindles from top to bottom gradually, and the particle that lower floor sorted is just very tiny.Conveying belt 1,3,4,7,9 connect each device respectively, and each operation is overlapped, and its operation is fast, and is easy.Working process is as follows: earlier rubbish is inserted above the conveying belt 1; deliver to after roughly selecting on the sorting equipment 2; establish eccentric wheel 13 on the sorting equipment 2; and be positioned on the conveying belt 3; the rubbish that sorts out is sent into again on the conveying belt 4 by conveying belt 3; in the conveying belt 4 magnetic rotary disk is housed; can simultaneously metal sundries be removed; removing back rubbish falls in the fermentation vat 5; fermentation back places and delivers in the baker 8 on the conveying belt 7 again by being arranged on thruster 6 in the pond; rubbish after the oven dry is sent in the pulverizer 10 by conveying belt 9 again and is pulverized, and adds an amount of micro-sending in the granulator 12 and make compound fertilizer granules in stirrer 11 after stirring, and is packaged into product export.
All adopt the conveying belt transfer mode between each device of the present invention, compact construction, easy to use, also can form automatization by computation.
