Description

The dustlessization separator of relative lightweight component in a kind of construction refuse regenerated material

Technical field

The utility model relates to a kind of separator of construction refuse regenerated material, in espespecially construction refuse regenerated material Dustlessization of relative lightweight component (such as plastics, textile fabric, bamboo and wood material) separates.

Background technique

In China, nowadays while the continuous fast development of the industries such as traffic and building, the demand of construction material is also got over Come bigger.A large amount of solid waste material can be generated during urban construction or removal.These obsolete materials are without any processing Just it is transported toward city suburbs or rural area, is handled in a manner of air storage or discarded landfill etc. mostly, and without personal management.Not only Ecological environment is destroyed, vast resources is wasted, expends land requisition expense, also increases additional rubbish cleaning construction cost, It influences the appearance of the city and certain detrimental effect is also generated to the soil and groundwater of surrounding, while clearing stacking process in building waste Dust, dust and sand of middle generation etc. are also one of the main source of air pellet pollution.

In order to preferably push comprehensive utilization of resources, develop sustainable circular economy, construction forms 21 century socialism Resource-conserving and environment-friendly society, it is necessary to by construction refuse resource.How will be at these construction refuse resource regeneration Reason, and the building waste aggregate after regeneration is put into engineer application, reach protection environment, resources sustainable development utilizes Purpose be that China needs one of the problem studied and solved at this stage.

Currently, according to the specific gravity of relative lightweight component in construction refuse regenerated material (such as plastics, textile fabric, bamboo and wood material) Difference carries out the main common principle that separation is current separator design.

Chinese utility model patent ZL03236218.8 discloses a kind of air-flow specific-gravity winnowing machine, with inclined surface The roller that fixed discharge nozzle and cooperation four movable support roller supports are helped is set on board, which is equipped with big sprocket wheel for dynamic The chain winding in power source simultaneously rotates roller, and several helical blades being equally spaced are equipped in roller and are equally spaced triangle gear Piece, helical blade front end form flat segments and then go deep into discharge nozzle, and a strength windmill utilizes baffle and rolling fixed on oblique conical section For the arrival end of cylinder close to without contacting, the baffle under the baffle using bending forms discharging notch.The technical solution utilizes air It repeats to blow separation principle, turn round to stir and provoke principle, stir and provoke principle and air draught concentration venturi tube generation attraction original Reason etc., realize different volumes, the plastics of different specific weight are effectively forced to separate.

Chinese utility model patent ZL200520008755.2 discloses a kind of plastic wind-power classifier, includes that pocket type removes Dirt device, feeder, transfer pipeline, has tortuous winnowing machine and separation expansion chamber at frequency conversion fan.The air outlet and complications of frequency conversion fan The lower end of winnowing machine is connected, and the air outlet of tortuous winnowing machine is connected with the wind inlet end for separating expansion chamber, separates going out for expansion chamber Wind end is connected by sack cleaner with the air intake of frequency conversion fan.The lower part of tortuous winnowing machine is equipped with material and enters just, at it Feeder is equipped at material inlet.The technical solution uses wind-force, and the plastics of different specific weight are separated.

Chinese utility model patent ZL.200820078855.6 discloses a kind of Specific gravity separation type garbage sorting plant, packet The first belt feeder, bellows, classifying drum screen and the foreign organic matter collecting net for passing sequentially through rack setting are included, is successively set in bellows It is equipped with electronic rotation double-edged fine-toothed comb and the second belt feeder, electronic rotation double-edged fine-toothed comb is by the rotary grate subframe and transmission shaft that are arranged on the rack Composition, castor fixing seat is connected on transmission shaft, several groups castor item, every group of castor item edge have been axially fixed in castor fixing seat The front end of even circumferential distribution, castor item has separation claw.The technical solution first half sorts (horizontal gas flow wind using horizontal wind Select, distribute formula), it is latter half of to use rotary pneumatic separating, the material of different specific weight is separated.

Specific gravity, can be differed bigger material and separated by these material sorting devices based on wind-force.But Wind election process be easy to cause fugitive dust, and secondary pollution can be caused to environment, at the same the regenerative material purity after selection by winnowing separates compared with It is low, limit the comprehensive utilization of construction refuse regenerated profile material.

Chinese invention patent application 201110073889.2 discloses in a kind of water of rubbish at separator, including access Reason main separate tank, the rewinding screw rod, feed screw device of water, and can be by rubbish along the setting wheel of water (flow) direction pushing; Rubbish is fallen in main separate tank from above main separate tank, is separated by specific gravity, heavy rubbish sink and through rewinding screw rod and It is set to feed screw device of the main separate tank by front end and is conveyed out main separate tank, the comparable rubbish of specific gravity with water floats on water In and through rewinding screw rod and be set to main separate tank and transfer out main separate tank by the feed screw device of rear end, it is having a specific gravity smaller than that of water Rubbish floats on the water surface and through water flow, setting wheel and the main separate tank of conveyer belt submitting for being set to main separate tank end.

However the device uses spiral discharging structure, fine precipitates are difficult to transport out, and helical structure is easy by card Firmly, device operation is influenced.In addition, the device only has conveying function, without agitating function, and water velocity is uneven, can not obtain The higher product of purity is obtained, and separates product and has large quantity of moisture, separating effect is undesirable.

It is to sum up told, the prior art be easy to cause fugitive dust, and secondary pollution, and obtained product purity can be caused to environment Lower, separating effect is undesirable, limits the comprehensive utilization of relative lightweight component in construction refuse regenerated material to a certain extent.
