Second screening machine, 7 structure and the third screening machine 8 are identical.In this way, only need to produce a kind of part, It can be suitable for whole machinery, to reduce production cost.
The rotating wheel of first conveyer belt 65, the second conveyer belt 66 and third transmission belt 81 being capable of ADSORPTION OF GOLD with magnetism Metal particles.In this way, the magnetic action of rotating wheel can be utilized, thus (mainly by the magnetic metal particle in raw material Iron) it adsorbs, avoid these impurity from entering in subsequent screening machine.
The splicing plate 3 being obliquely installed, the splicing plate 3 are provided between the feed conveyor belt 2 and the feed inlet 11 Lower end is located at right above the feed inlet 11 and upper end is located at the lower section of the feed conveyor belt 2, the band of the feed conveyor belt 2 Wheel belt is magnetic adsorbable metal charge, and 3 bottom of splicing plate is provided with vibrating member 31.The belt wheel band of the present apparatus is magnetic, from And feed inlet 11 can be entered to avoid metal charge, then damage crushing washing portion 1.Also, in order to improve transfer efficiency, in splicing 3 bottom of plate is arranged vibrating member 31 and, by the plastics on splicing plate 3, is smoothly delivered to charging by the effect of vibration of vibrating member 31 Mouth 11.
The crushing washing portion 1 is connected with water inlet pipe, the water inlet pipe input clean water to crushing washing portion 1 inside Plastics are cleaned and are conveyed.The effect of water removes the impurity on its surface first is that plastics can be cleaned;Second is that also providing one Spot lubrication effect, can protect the shredder mechanism in crushing washing portion 1;It is thirdly exactly that broken plastics can be carried out defeated It send.
It is provided with skewback 41 in the conveying drying portion 4, relief hole 411, the row are provided on the skewback 41 Material hole 411 is equipped with baffle 412, is additionally provided with filter 43 on the skewback 41.The plastics conveyed on drying conveyor 60 Grain, under the action of the factors such as hot gas, understands some and falls.Therefore, the present apparatus is provided with skewback 41 and filter 43 Cooperation, so that these plastic pellets for being can be discharged by relief hole 411.These plastic pellets are to have already passed through broken and scavenger Sequence, once, only need by drying.In this way, it is possible to save working time.
It is located at upper 51 two sides of outlet portion in the conveying drying portion 4 and is respectively arranged with partition 44.By the way that partition is arranged 44, it can either avoid being located at the plastic pellet dried in upper outlet portion 51, not will receive the droplet come out from discharge nozzle 12 It influences, also, limit for height can also be carried out to the plastic pellet on drying conveyor 60, to guarantee the quality of drying.
4 bottom of conveying drying portion is provided with sewage draining exit 421, and the sewage draining exit 421 is connected with sewage pipe 422.In this way Setting, sewage can be discharged from sewage draining exit 421, will not influence the plastic pellet dried in conveying drying portion 4, and dirty Water can be recycled, energy conservation and environmental protection after purification.
When the present apparatus works, the recycled plastic product classified will be needed to be put into feed inlet 63, in this way, these plastic products enter To 61 inside of screen cylinder.Screen cylinder 61 is provided with material-dropping hole and is enclosed with screening net, therefore, some to pass through screening net The plastic products of small volume will enter blanking gap 611, then fallen again by the second discharge port 64 in the second transmission On band 66, eventually passes through the second conveyer belt 66 and enter the progress sifting sort of third screening machine 8.And the biggish plastic products of volume are protected It stays in screen cylinder 61.And screen cylinder 61 is driven by the motor, can gyrate.The plastic products of these large volumes are in baffle It under the action of 62, can gradually be subjected to displacement, finally leave screen cylinder 61 from the first discharge port 621, enter the first conveyer belt On 65, then it is transported to the second screening machine 7 and carries out sifting sort.Second screening machine 7 is identical with the structure of third screening machine 8, work It is also consistent to make principle.
Saline solution 82 is perfused in third screening machine 8, after plastic products transport comes, heavy plastic products then can Precipitating is gone down, and the small plastic products of specific gravity will float on liquid level.And can be rotated always when the work of runner 83, therefore, set thereon The fishing feed bin set will pick up the plastic products of these floatings, be then placed on discharge belt 831 again, therefore these specific gravity Small plastic products just are screened out.
The plastic products to go down are precipitated, can be accumulated in the bottom of third screening machine 8.And the bottom of third screening machine 8 is provided with The plastic products of these accumulations can be transported out outside third screening machine 8 by third conveyer belt 81, the third conveyer belt 81.
In order to improve the precision of screening, a greater variety of plastics are isolated, can be installed at 8 rear of third screening machine more Screening machine 801, the structure of these screening machines 801 is consistent with third screening machine 8.Then pass through the saliferous of adjusting saline solution Amount, it will be able to so that the plastic products of different specific weight float on liquid level, then are picked up by fishing feed bin, separation.
The work of second screening machine 7 and third screening machine 8 is identical.
The present apparatus is provided with horizontal stripe to improve the transfer efficiency of conveyer belt on a moving belt.These horizontal stripes are capable of providing Larger frictional force helps to convey.
The plastic part to come from the transport of sifting sort mechanism is first dropped on splicing plate 3, then by feed conveyor belt 2 Entering feed inlet 11 by splicing plate 3, hence into progress crushing washing process in crushing washing portion 1.Then pass through discharging Pipe 12 enters conveying drying portion 4 and carries out drying and processing.Plastic pellet carries out defeated on the drying conveyor 60 in conveying drying portion 4 It send, and is oven-dried under the drying hot air acting that puff prot 54 sprays.Final plastic pellet leaves from discharge port 7.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims Subject to, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that each fall within of the invention Protection scope.
A kind of plastic material sorting unit of the invention can classify the plastic products of recycling first with physical method, Then break process is carried out again, is cleaned and is conveyed using water, is finally carrying out dry tack free processing, so that output of classifying is dry Net finished plastic particle, has outstanding classification drying effect, and energy conservation and environmental protection does not pollute the environment.
