Fig. 1 is a kind of wind electricity blade recovery and treatment method flow chart of the present invention;
Fig. 2 is resin particle, glass granule and light material particle separation schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
In the wind electricity blade recovery and treatment method of the present embodiment, by the full-size vanes block less than 2m (artificial or other modes cut after vanes block, vanes block is block, block longest edge size is less than 2m, as: 2m × 1m × 0.2m) it is broken into the full-size particulate matter less than 5cm and (is preferably 8mm, so as powder process afterwards), and described particulate matter is easily separated by material type, isolate resin particle, glass granule and light material granule (including: PVC granule, the light materials such as Ba Shamu, material density is lower more than 10 times than glass fibre). concrete steps are as it is shown in figure 1, include:
Step S110, adopts the first shredder that the full-size vanes block less than 2m carries out first time and tears up, and the vanes block after tearing up is transported to the second cyclopentane gas detector.
Step S120, the second shredder first time is torn up after vanes block carry out second time and tear up, formed be smaller in size than first time tear up after vanes block, the vanes block transmission after second time being torn up is to pulverizer. The present embodiment, adopt twice varigrained shredder (secondary shredder granularity is less than secondary shredder granularity), vanes block being torn up the size of particulate matter close to 5cm (being namely a bit larger tham 5cm), compares and once tear up, fragment size is evenly.
Step S130, pulverizer by second time tear up after vanes block pulverize, form the described full-size particulate matter less than 5cm.
Step S140, is easily separated described particulate matter by grader and airflow separator, isolates resin particle, glass granule and light material granule.
The wind electricity blade recovery and treatment method of the present embodiment achieves and reclaims resin particle, glass granule and light material granule by type, and the material of the particulate matter relative bulk made utilizes field wider, to carry out secondary utilization, it is to avoid material waste, improve utilization of materials.
Owing to blade material hardness is high, toughness is strong, and Heavy Weight, process extremely difficult for blade material, it is processed into the material less than 5cm currently without more perfect processing mode, and core, glass fibre, resin are effectively separated, in order to solve the problems referred to above, in the present embodiment, step S140 includes:
As shown in Figure 2, described particulate matter is blown into (shown in solid arrow) by materiel fan and is arranged in the grader 1 (particulate matter enters grader 1 from the mouth shown in solid arrow) above airflow separator 2, by dust, (air-flow takes away dust to the air-flow that the classifying turbine 11 of grader 1 produces, air-flow as the dotted line arrows, enters the flow process of dedusting and filtration treatment) and described particulate separation.
The particulate matter freely falling body separated is to described airflow separator 2, to isolate resin particle, glass granule and light material granule.
Particulate matter is subject to the combined effect of mechanical vibration and ascending air simultaneously after entering airflow separator 2. According to material physical characteristic, different materials can carry out well-regulated sequence motion by proportion shape. Move upward than great and that diameter is big granule, discharge from higher discharging opening 21, the granule that proportion is little and diameter is little moves downward, discharge from relatively low discharging opening 22, the lighter light material granule of quality flows away (as shown in dotted line arrow) with ascending air mouth from above, thus resin particle, glass and PVC being easily separated. Specifically, resin particle will flow out below airflow separator 2, glass granule flows out above airflow separator 2, the light material granule of some relatively lightweights is by under the effect by the negative-pressure air-flow above airflow separator, it is inhaled into another the first cyclopneumatic separator, discharges below the first cyclone separator.
In order to avoid environmental pollution, also include carrying out dedusting and filtration treatment to from the isolated air-flow with dust of described grader. Dust is separated with gas by dust by cyclopneumatic separator, and dust is collected by the lower section of the second cyclopneumatic separator, then air-flow imports the abnormal flavour in the dust removal and filtration pipeline remaining a small amount of dust of filtration and air-flow.
And, airflow separator air-flow out is by discharging after dust removal and filtration, light material granule is separated by the first cyclopneumatic separator with gas, and light material granule is collected by the lower section of the first cyclopneumatic separator, then air-flow imports the abnormal flavour in dust removal and filtration pipeline removing air-flow.
In the present embodiment, in step S120, by the vanes block transmission after second time being torn up with the transmission band of magnetic separator to pulverizer, damage pulverizer to avoid the metalwork in blade to enter pulverizer.
In the present embodiment, the product after broken may be used for but is not limited to following field:
Resin particle after broken and glass granule, especially 2cm particles below can be done packing material, reinforcing material and add tough material etc., as: do mixed earth reinforcing material, artificial stone reinforcing material etc., to strengthen the intensity of these concrete and artificial stone, reduce cost simultaneously. The equally possible packing material that does of light material granule is to alleviate finished product density and weight.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
