Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
See Fig. 1, building waste compound is under the control of blanking buffering chamber (1), oscillating feeder (2) is entered with certain inlet amount, under the vibration of oscillating feeder (2), fall on belt conveyor (3), travel forward along belt conveyor (3), then fall by belt conveyor (3), when entering the viewing area of image capturing system in color separatory vessel (10), the building waste compound of CCD imaging device (4) to motion carries out shooting imaging, and form data signal output, processed by information processing and control system, judge the material needing to select, generate control signal and control jet apodization system (6) action or duty.During IMAQ and signal transacting, building waste compound continues to fall, enter the dead ahead of jet apodization system (6) nozzle, now, jet apodization system (6) is ready under the control signal of information processing and control system, if not heterochromatic materials such as common brick blocks, then close corresponding nozzle, allow material freely-movable enter discharging opening 1 (7); If heterochromatic materials such as common brick blocks, then open corresponding jet, changing it departs from original movement locus, enters discharging opening 2 (8), completes the color sorting of building waste thus.
Color separatory vessel (10) is the core apparatus carrying out material particles acquisition of information, is also the dust arrester of system simultaneously, can effectively isolates the dust generated in assorting room, free from environmental pollution.CCD imaging device (4) is provided with camera lens and linear array/area array CCD, by camera lens, the granule materials by observation station is imaged on CCD clearly with certain multiplication factor, changed by A/D, then information processing and control system is transferred to, optical adjusting frame (5) be used for regulate CCD imaging device (4) position, to ensure the Obtaining Accurate of material image.Light regulates lamp (9) to be mainly used to as CCD imaging device (4) imaging provides light illumination, to ensure brightness during material Image Acquisition.The digital image information of acquisition is sent to information processing and control system by color separatory vessel (10), information processing and control system can be divided into two parts, a part is the information processing system of acceptance and analysing digital image information, another part is the control system generating control information according to the analysis result information of information processing system, and the control information of generation completes material sorting for controlling jet apodization system (6).
The utility model is described in further detail below, and blanking buffering chamber has been used for entering of raw material and controlling, and needs, by controlling blanking buffering chamber blanking velocity, to select the coupling of speed with the demand and material look that meet vibrator.Building waste compound forward upward is dished out by vibration by oscillating feeder, allows material can fall on belt conveyor by certain speed, and by ensureing that raw material disperses uniformly with the cooperation of Belt Conveying motor speed, reduces stock jump as far as possible.Because this building waste color separation system is compared with other photoelectric colour sorter, output improves greatly, and therefore the vibration ability of oscillating feeder and blanking velocity also increase accordingly greatly.Belt conveyor below vibrator, and leads to color separatory vessel inside, and material falls by belt conveyor, enters the viewing area of image capturing system, and keeps appropriate distance with color separatory vessel point of observation.This belt conveyor mainly contains two functions, and one is limit building waste compound in appropriate width range, and two is ensure that building waste compound moves to color separatory vessel point of observation with certain speed.In addition, belt conveyor also must ensure the dispersed of material and easy motion.CCD imaging device is compared with conventional electrophotographic system, by face battle array or linear array imaging, there is high resolution ratio, two magnitudes can be improved against the background of the prior art, complete the high-resolution imaging of the individual particle to most of building waste compound, instead of as conventional electrophotographic system, each picture point may have the superposition of multiple material particles, thus obtaining additional effect is substantially increase signal to noise ratio.Information acquisition system is mainly combined with color separatory vessel, completes collection and the amplification of information.Information processing system mainly completes the post processing of Information Monitoring, comprises the alignment of building waste compound, segmentation, process and judgement etc.Jet apodization system mainly under control of the control system, jet to material certain time such as the fragments of brick in building waste, jet direction is vertical with the direction of motion of material, with what ensure maximal efficiency, the materials such as fragment of brick are departed from former moving line, and dropping in discharging opening 2, jet apodization system has carried out selecting heterochromatic material the bests such as fragments of brick by the selection of the length of jet time, the size of air pressure and jet initial time.
Last it is noted that obviously, above description is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among the protection domain of the application.
