The treating method for urban domestic rubbish comprises the following steps of: (1) collecting rubbish by a rubbish throwing box which is provided with sieve holes; (2) delivering the rubbish throwing box to an initial selection machine; (3) dumping the rubbish in the rubbish throwing box to the initial selection machine; (4) sorting the rubbish by the initial selection machine in advance for sorting out large bricks and large and long organic matters; (5) crushing the large and long organic matters; carrying out magnetic selection and screening; using the screen underflow for compost or as a brick manufacturing raw material; carrying out wind selection on the screen overflow after drying; and (6) obtaining different matters by wind selection to be respectively used according to different types. The rubbish throwing box in the treating method of the domestic rubbish comprises a box cover and a box body, wherein the lower part of the box body is provided with the sieve holes. The invention decreases the content of water in the rubbish, reduces stirring, shortens production period, and reduces environmental pollution and energy consumption in the process of treating the rubbish.

Description

The processing method of domestic waste and device thereof
Technical field
The invention belongs to environmental technology field, a kind of processing method and device thereof that is used for domestic waste.
Background technology
Country and governments at all levels have classified Urban Domestic Waste Comprehensive Treatment as the key project of social sustainable development at present, but the corresponding hysteresis of treatment of urban garbage technology.The processing method of Chinese patent application 200910074832.7 house refuses is owing to be mingled with a large amount of moisture content in the collection process of rubbish, easily make in the domestic waste storage and transport process, the easy fermentation of easy ponding is grown mosquitos and flies and is caused preliminary pollution, repeatedly stirring and enter behind landfill yard and the destructor plant three to ten days production cycles in the follow-up product fortune process more makes pollution level continue to worsen to deepen, in process because the big consumption that increases energy of rubbish moisture content.
Summary of the invention
The objective of the invention is to provide a kind of method and device thereof of domestic garbage comprehensive processing, reduce the water content in the rubbish, minimizing is stirred, and shortens the production cycle, reduces environmental pollution, reduces the energy consumption in the garbage disposal process.
The present invention realizes by following steps:
(1) rubbish that uses the bottom to be provided with sieve aperture is thrown in case and is collected crude waste;
(2) rubbish of filling is thrown in case is transported to the special use at primary election machine place with special garbage removing cart lifting means;
(3) rubbish directly rubbish thrown in the case of Zhuan Yong lifting means is dumped into the primary election machine inlet capable;
(4) rubbish carries out pre-sorting through the primary election machine, sub-elects bulk masonry and particle diameter greater than the organic pre-sorting rubbish of greatly enhancing of 300mm;
(4) the big brick stone that sub-elects is pulverized the back as brick-making raw material;
The organic matter that greatly enhances that (5) will sub-elect is broken into the material that particle diameter is not more than 100mm, after magnetic separation, mix with pre-sorting rubbish, sending 20~25mm rotary screen to sieves, screenings is used for after compost or the high-temperature sterilization as brick-making raw material, enter rubbish air blasting device after the oversize drying and carry out selection by winnowing, according to the proportion selection by winnowing of material go out heavy substance, organic matter, not recyclable or combustion thing and light plastic are planted in corruption;
(6) heavy substance that goes out of selection by winnowing reclaims metal through magnetic separation, and sorts out high-temperature sterilization behind the battery, and is broken as brick-making raw material;
(7) corruption that goes out of selection by winnowing is planted organic matter and is used for compost or directly advances incinerator and burn;
(8) be used to prepare garbage derivatived fuel after the not recyclable combustible fragmentation that selection by winnowing goes out;
(9) light plastic that goes out of selection by winnowing is used to prepare plastic reclaimed particle.
Owing to adopt the technical scheme of the invention described above, have the following advantages compared with the prior art:
One, in the garbage collection process, the moisture content in the rubbish obtains getting rid of, and reduces the cost in rubbish transportation and the processing procedure, the minimizing expense.
Two, reduce refuse moisture, suppressed the rubbish fermentation probability, reduced odor pollution.
Three, reduce rubbish and produce stirring in the fortune process, alleviate artificial labour intensity.

Fig. 2 is that rubbish used in the present invention is thrown in the case front view.
Fig. 3 is that rubbish used in the present invention is thrown in the case side view.
The specific embodiment
The present invention is further described below in conjunction with accompanying drawing:
Embodiment 1
Shown in Figure 1, process flow diagram of the present invention.
(1) rubbish that uses the bottom to be provided with sieve aperture is thrown in case and is collected crude waste;
(2) rubbish of filling is thrown in case is transported to the special use at primary election machine place with special garbage removing cart lifting means;
(3) rubbish directly rubbish thrown in the case of Zhuan Yong lifting means is dumped into the primary election machine inlet capable;
(4) rubbish carries out pre-sorting through the primary election machine, sub-elects bulk masonry and particle diameter greater than the organic pre-sorting rubbish of greatly enhancing of 300mm;
(4) the big brick stone that sub-elects is pulverized the back as brick-making raw material;
(5) greatly enhance organic matter and be broken into the material that particle diameter is not more than 100mm, after magnetic separation, mix with pre-sorting rubbish, sending 20~25mm rotary screen to sieves, screenings is used for after compost or the high-temperature sterilization as brick-making raw material, oversize dewaters through centrifugal drier, enter rubbish air blasting device and carry out selection by winnowing, according to the proportion selection by winnowing of material go out heavy substance, organic matter, not recyclable or combustion thing and light plastic are planted in corruption.
(6) heavy substance that goes out of selection by winnowing reclaims metal through magnetic separation, and sorts out high-temperature sterilization behind the battery, and is broken as brick-making raw material;
(7) corruption that goes out of selection by winnowing is planted organic matter and is used for compost or directly advances incinerator and burn;
(8) be used to prepare garbage derivatived fuel after the not recyclable combustible fragmentation that selection by winnowing goes out;
