Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1 and Figure 2, one way of life rubbish sludge reduction onsite integrated apparatus, comprising: device body side is provided with lifting device 1, for promoting rubbish and pouring the breaker 2 being positioned at device body top into; Breaker 2 is exported and is connected by conveying device 3 between the charging aperture 4-1 of aerobic reaction double shell 4; Described aerobic reaction double shell 4 is made up of the aerobic reactor of two series connection, and be all provided with one in each aerobic reactor along axle center for pushing and stirring the stirring rotator 8 of material, stirring rotator 8 one end is connected with the drive unit 10 driving its rotation; The discharging opening 4-5 of aerobic reaction double shell 4 divides into vibratory sieve 7.
Operation principle of the present invention and process as follows:
The tubbiness rubbish collected is promoted by dustbin lifting device 1, tilt to pour breaker 2 into and carry out broken bag break process, breaker 2 is by its shear action, and by composting or sorted refuse breaking to particle diameter 3 ~ 7cm, the rubbish after fragmentation falls in conveying device 3; Rubbish after fragmentation is delivered to charging aperture 4-1 by conveying device 3, aerobic reaction double shell 4 carries out associating stepwise fermentation, by at the layer-transferred conveying stirring of stirring rotator 8 and control temperature 60 ~ 70 DEG C in cylindrical shell, by material fermentation, fermentation aerobic environment is realized by blast aeration, living beings particle diameter is fermented dehydration gradually, and particle diameter reduces.Other impurity cannot ferment, and keep original particle diameter 3 ~ 7cm; Material after fermentation in vibratory sieve 7, to realize that living beings are homogeneous, removal of impurities through discharging opening 4-5 by material difference through vibratory sieve continuous shaking.Obtain purity be greater than 95% living beings of becoming thoroughly decomposed can direct utilization.Agitating device is fixed in reactor, is pushed by the material entering reactor by conveyor screw along convergent direction, arrives stirrer paddle region.Stirrer paddle, by stirring material, makes it fully mix and ferment.The material fermented the most at last exports to outside reactor, realizes processing continuously.
As shown in Figure 6, stirring rotator 8 is made up of central shaft 8-1, conveyor screw 8-2 and stirrer paddle 8-3, and conveyor screw 8-2 is fixed on this central shaft 8-1 side with one heart and is tapering type extension from axle head to axle centre position, for axially pushing material; Stirrer paddle 9 and conveyor screw 7 are coaxially fixed on this central shaft 8-1 opposite side; The laying standard of some stirrer paddles 9 is: the propelling movement power not producing centrally axle 8-1 axis in rotary course.
And the reason arranging this laying standard is: in fill process, if stopping charging, then conveyor screw can not produce propelling movement power to the bank body in reactor, and the pushed circumferential stirring only receiving stirrer paddle to stirrer paddle, but can not pushed outwardsly further give.Therefore, the same batch of material entered all can concentrate in a certain FX, and can not with the mixing of materials of other batches.Current one batch of material entered is fermented to time to a certain degree, can add materials in conveyor screw further, utilizes new material outwards to be pushed by fermented-material, forms layering fermentation system in reactor.This system can reduce the composite rate of new marine store greatly, effectively controls the solid material time of staying in the reactor, improves the degradation efficiency of outputting material, promotes end product quality.
In present embodiment, and increase the raising blade stirring rigidity of stirrer paddle, improve anti-interference intensity and toughness, stirrer paddle 9 cross section assumes diamond in shape, and rhombus major axis is axially parallel with central shaft 8-1.During stirring, stirrer paddle contacts material with largest face, fully stirs the material of blade periphery, makes it ferment evenly.
