Detection module 10 detects temperature value, humidity value, pressure value, biogas concentration and the carbon dioxide in fermentation cabin 4 in fermentation process
Concentration, and shown by the display screen on switch board 2, while remote controllers 1 are sent to by switch board 2, requirement of fermenting
Humidity value is 30% ~ 75%, and when humidity value is less than 30%, remote controllers 1 control warning device to provide warning message, same to time control
Cabinet 2 processed controls water pump two to work, and the water in water tank 6 is sprayed in house refuse through spray equipment 11, realizes the purpose of humidification,
When the pressure value that pressure sensor detects is the mpa of 0.2mpa ~ 0.3, and the biogas concentration that biogas concentration tester detects is
When 90% ~ 95%, remote controllers 1 control warning device to provide alarm, and switch board 2 controls induced-draught fan to work, in fermentation cabin 4
Biogas recovered pipeline be recycled in methane recovery tank 8, when fermenting between be 7 ~ 10 days, and temperature sensor detects
When temperature value in fermentation cabin is 70 DEG C ~ 80 DEG C, fermentation is completed, and remote controllers 1 control warning device to provide alarm,
In the presence of induced-draught fan, the biogas in fermentation cabin 4 is recycled in methane recovery tank 8, is detected when biogas concentration tester
When the concentration of biogas is less than 5%, remote controllers 1 control warning device to provide alarm, and staff is opened in fermentation cabin 4
Closure, while send instruction to switch board 2 by remote controllers 1, switch board 2 controls ventilating fan 13 to work, can also
Directly ventilating fan 13 is controlled to work by switch board 2, then the carbon dioxide in fermentation cabin 4 is discharged fermentation cabin 4 through exhaust outlet, together
When gas concentration lwevel tester detection fermentation cabin in carbon dioxide concentration, when the concentration of carbon dioxide reaches requirement most
During low value, staff enters fermentation cabin and carries out subsequent operation.
Step 3：Sort, the house refuse for completion of being fermented in step 2 is transported in mechanism for sorting 3, through Belt Conveying
The 15a of machine one is transported in primary screener mechanism, and after primary screener mechanism carries out primary screener, the small garbage filtered out divides
It is not collected through collecting the 32c of conveyer belt three, collecting the 32d of conveyer belt four and collecting the 32e of conveyer belt five, remaining rubbish is defeated through belt
Send the 15b of machine two be transported to m types rotation select in formula sorter 16, house refuse by m types rotation select formula sorter 16 smash and it is high abandon,
Falling on chain type screening conveyer belt 18, in dropping process, the polybag in rubbish is blown to one end of case 22 by winnowing machine 19, and
Through collect the 32a of conveyer belt one collect, the larger rubbish of volume be transported to chain type screening conveyer belt 18 end and through collect it is defeated
The 32b of band two is sent to collect, the rubbish of small volume is dropped on the 15c of belt conveyor three through chain type screening conveyer belt 18, and rubbish exists
Into shredder assemblies, in the presence of shredder assemblies, waste or used plastics and waste and old clothing can be passed through during the 15c of belt conveyor three
Organoclay on clothes effectively comes off, while blade can crush waste and old clothes, avoids waste and old clothes from being wound into chain type screening and passes
Send on band 18, with the 15c of belt conveyor three motion, the rubbish fallen on the 15c of belt conveyor three is transported to magnetic separator
At 20, metal of the metal after the screening of magnetic separator 20 in rubbish in rubbish is collected through metal collection conveyer belt 37, remaining
Rubbish is transported on vibratory sieve 21 through the 15d of belt conveyor four, and for example waste and old lighter of the larger rubbish of volume, plastic sheet etc. pass through
The 32f of conveyer belt six is collected to be collected, by upper sieve and not by the smaller rubbish of lower screen through collecting the 32g quilts of conveyer belt seven
Collect, be collected by the rubbish of lower screen through collecting the 32h of conveyer belt eight.The present invention realizes the recycling, innoxious of rubbish
Processing, completely eliminates waste water, waste gas and the waste residue in garbage processing procedure, caused by effectively prevent house refuse possibility
Secondary pollution.
To sum up, the present invention produces a desired effect.
