Description

The broken removal of impurities complete device of horizontal rubbish from cooking

Technical field

The present invention relates to a kind of rubbish pretreatment unit, especially relate to the broken removal of impurities complete device of a kind of horizontal rubbish from cooking.

Background technology

Along with the raising of socioeconomic development and living standards of the people, the generation of China's house refuse continues to increase.2011, China's domestic waste amount of clearing reached 1.64 hundred million tons, became rubbish and surrounded one of the most serious country in city.At present, 8 cities such as Beijing, Shanghai have successively been carried out categorized consumer waste and have been collected pilot work, house refuse are divided into the large class of rubbish from cooking, recyclable rubbish, Harmful Waste and Other Waste four.As the main component of house refuse, rubbish from cooking accounts for 45% ~ 60% of rubbish total amount; Therefore, the reasonable disposal of rubbish from cooking will become China's Classified Collection of Municipal Solid Wastes Sources decreasing and recycling work and whether have the crucial restrictive factor of sustainability.Exploitation rubbish from cooking application technology as the second resource and equipment research have important practical significance.

At present, domestic and international rubbish from cooking resource technology mainly comprises Fertilizer Transformed, fodder, energy three kinds of modes.Rubbish from cooking recovery energy technology, owing to can realizing kitchen waste reduction and biomass waste being changed into the feature of clean energy resource-methane, becomes domestic and international organic garbage treatment disposal technology study hotspot and development trend.But, different from developed country, China's kitchen garbage component is complicated, by the impact of resident living mode, in rubbish from cooking, the non-biodegradable impurity such as plastics is up to 20% ~ 30%, very easily causes anaerobic digestion reaction vessel to entirely collapse if directly carry out anaerobic fermentation without the rubbish from cooking of broken removal of impurities process.Therefore, the research and development bottleneck that first China's rubbish from cooking recovery energy technology must break through rubbish from cooking efficiency crushing removal of impurities pretreatment complete set technique and equipment be realized.

Because developed country's refuse classification system is perfect, after classification, waste component is single, and recycling is relatively simple, therefore a lot of external rubbish pre-processing device cannot be applicable to the numerous and diverse garbage disposal of China's component.At present, domestic existing rubbish pre-processing device is handling object mainly with non-classified house refuse, and specific aim is not strong.Have in processing procedure that broken bag poor effect, heavy substance are serious for equipment attrition, polybag wrapping phenomena serious, living beings separative efficiency is not high, discharging particle diameter is uneven directly cannot carry out the problems such as anaerobic methane production, limit its further industrialized development.Therefore, for realizing the direct anaerobic fermentation recovery energy of rubbish from cooking, a set of pre-processing device for China's rubbish from cooking characteristic is developed imperative.

Summary of the invention

In order to overcome the defect of pretreatment or equipment in background technology, the object of the present invention is to provide the broken removal of impurities complete device of a kind of horizontal rubbish from cooking for the rubbish from cooking after categorized consumer waste, acquisition can be directly used in the living beings of anaerobic methane production, and the recyclable resource such as highly purified plastics, metal.

Operation principle of the present invention is as follows:

As shown in Figure 1, four functional areas of the present invention realize different functions, and rubbish from cooking can realize heavy substance (as glass, metal, pottery, stone etc.) after four functional areas, living beings, the efficient separation of plastics, and the effect of four functional areas is as follows:

(1) charging bag breaking area:

Rubbish from cooking is evenly transported in device by conveying worm 1, enters into cylindrical shell along conveyance conduit; Conveying pipeline inner wall inclination arranged crosswise has 2 ~ 4 groups of stationary saw serrated knives 2, in the process that material moves straight down by the thrust of gravity and material below, polybag in material is carried out broken bag and tentatively fragmentation by blade, reduces polybag for the parcel of material, living beings are fully exposed.

(2) hammer crushing district:

When material is after broken bag, enter hammer crushing district through charging aperture 3, broken up by a series of (totally 3 ~ 5 groups, often organize 3 ~ 6) jump bit 17; Utilize the heavy substance such as glass, pottery compared to living beings, plastics poor toughness simultaneously, easily produce the characteristic of brittle break, heavy substance is carried out fragmentation, broken size controlling between 10-30 mm, through interior shaft screen 16.In addition, the tup flat side of a hammer of jump bit 17 is designed with angle of inclination, can produce carrying capacity forward to remaining material, thus promotes remaining material and move right, and enters next functional areas.

(3) heavy substance Disengagement zone:

After heavy substance is crushed to target grain size, through interior shaft screen 16, stop the living beings outer shaft screen 15 compass screen surface being less than 20 mm ~ 30 mm with part and mix.The angle cutter that screw arrangement one group is sharp on interior shaft screen outer wall.Circular knife group 18, along with interior shaft screen 16 low speed rotation, utilizes living beings different from the intensity of heavy substance, living beings is carried out second-time breakage, makes its particle diameter be less than outer shaft screen 15 aperture, through outer shaft screen 15, collects in living beings discharging bin 8; And heavy substance cannot be broken, simultaneously angle cutter spacing 10 mm ~ 20 mm, makes heavy substance cannot be transported to left heavy substance discharging opening 6 through circular knife group 18 with the rotation of circular knife group 18, realizes heavy substance and remove in mixed material.Simultaneously, shaft screen 7 and outer shaft screen 8 be synchronized reverse rotation, prolongation material and angle cutter time of contact, make feed separation effect better.Interior shaft screen 7 is driven by screen drum motor 5 by gear drive with outer shaft screen.

(4) living beings Disengagement zone:

Living beings Disengagement zone cannot be transported to through the living beings of interior shaft screen 16 and plastics, being undertaken shearing by the shearing-crushing cutter group 14 of High Rotation Speed be main, punching type is auxiliary fragmentation, living beings are crushed to below screen drum aperture, through screen drum 13, realize living beings and be separated with plastics.Meanwhile, plastics can be carried out certain fragmentation by shearing-crushing cutter group 14, prevent the winding of bulk plastic.And the living beings after screening are collected together with the isolated part biological matter in front end, carry out follow-up recycling.Plastics are scraped ejecting plate 10 by plastics and are transferred to from plastics discharging opening 11, collect.Shearing-crushing cutter group 14 and jump bit 17 are all arranged on main drive shaft 4, driven, realize coaxial synchronized rotation by spindle motor 9.Screen drum 13 is connected with interior shaft screen 16, realizes coaxial synchronized rotation.
