Fig. 2 present invention process device therefor latter half structural representation.
Detailed description of the invention
Below in conjunction with the equipment structure chart used in the present invention process shown in Fig. 1, present invention process flow process is described in detail.
This technological process is completed by following steps:
A, from old rubbish in rough segmentation plastic sheeting out, main body is plastic sheeting, but is wherein mingled with the foreign matter that some do not allow water, as brick, stone, metallic foreign body etc., and general bind dirt on plastic sheeting in addition.Plastic sheeting is sent on belt material-feeding machine 1 by mechanical gripping car, under the transmission of belt, sends into drum washing machine 3.Drum washing machine comprises inside and outside double-layer structure, and outer for being covered with the cylinder of circular hole, cylinder inner wall is equipped with triangular steel plate array, cylinder two ends are arranged on bearing and also can rotate under power drive, inside is turning cylinder, and turning cylinder is equipped with blade, and cylinder interior is equipped with sparge pipe simultaneously.When plastic sheeting enters in cylinder, cylinder and turning cylinder rotating in same direction, blade does not stop to pat plastic sheeting, sparge pipe is sprayed water, dirt on plastic sheeting to come off down one after another beating, along with flowing water falls from circular hole together, be receiver below cylinder, addle flows into sedimentation basin 2 through receiver and precipitates.Drum rotation speed 7-8 rev/min, turning cylinder rotating speed 150-180 rev/min.Plastic sheeting through first time wash laggard enter winnowing separator 4.
B, plastic sheeting enters the laggard sector-style choosing of winnowing separator 4, winnowing separator bottom is conveyer belt, seal case is covered with above conveyer belt, seal case and both ends open parallel with conveyer belt, one end open is equipped with blower fan, the other end is equipped with screen cloth, conveyer belt moves to blower fan direction, plastic sheeting enters into defeated moving and brings in the middle part of seal case, move to blower fan direction, be blown up and conveyer belt reverse movement simultaneously, blow to screen cloth end to fall and enter the second belt material-feeding machine 5, screen cloth has the function of unloading wind, the weights such as brick stone contained in plastic sheeting cannot be moved by wind, fall along with conveyer belt moves to blower fan one end and be collected, blast 1200-1500Pa during air blast, air quantity 8000M
3/ hour.
C, plastic sheeting enter bath disintegrating machine 7 after the second belt material-feeding machine 5, bath disintegrating machine 7 is the turning cylinder of High Rotation Speed, which is provided with blade, plastic sheeting can be smashed, limit bath is also wanted to carry out second time washing while smash, dirt residual on plastics in the process smashed is again by wash-out, and broken rotating speed 500-550 rev/min, the plastic sheeting after fragmentation flows out from the bottom of bath disintegrating machine and enters the first bath screw feeding machine 8.In this step, can also set up material loading platform 6, plastic sheeting first carries material loading platform through the second belt material-feeding machine, then enters bath disintegrating machine again by material loading platform.Because the second belt material-feeding machine discharging is intermittent, and disintegrating machine of washing by water needs continuous feed, and the second belt material-feeding machine discharging carries out buffering accumulation through platform, by artificial manual to bath disintegrating machine uniform feeding, is conducive to the stability of technique.
D, after plastic sheeting enters the first bath screw feeding machine 8, carry out after third time washing, being transported to the first bath friction cleaning machine 9 through bath and carry out the 4th washing, wherein first bath screw feeding machine 8 outside for being uniformly distributed the cylinder of circular hole, inner for rotating auger, plastic sheeting is carried by auger, water after flushing leaks down to return sedimentation basin through cylinder, first bath friction cleaning machine 9 has circle tube inner wall, circle tube inner wall top is provided with inlet opening, bottom is provided with leaking hole, it is pivoting friction axle in the middle part of circle tube inner wall, pivoting friction axle is equipped with friction plate, pivoting friction axle rotating speed is 400 revs/min,
E, plastic sheeting out enter the second bath screw feeding machine 10 afterwards from the first bath friction cleaning machine 9 and carry out the 5th washing, then enter the second bath friction cleaning machine 11 and carry out the 6th washing;
F, plastic sheeting out enter the 3rd bath screw feeding machine 12 afterwards from the second bath friction cleaning machine, then enter screw squeezer 13 to extract, be double helix auger in the middle of screw squeezer, outer cover has cylinder, cylinder is distributed with circular hole, the port of export of screw squeezer is equipped with hydraulic pressure and goes out mouth, and entrance point is equipped with feeding screw, and the plastic sheeting extracted goes out mouth from hydraulic pressure and extrudes;
G, the plastic sheeting extracted enter beater 14 and break up, and then enter comminutor 16 through the 3rd belt material-feeding machine 15 and carry out granulation, be stored into gathering-device 17 after plastic grain of making is collected.
Respectively walk the sewage cleaned in present invention process and enter sedimentation basin, after purification, carry out circulation flushing use, be conducive to saving water resource, reduce costs.
More than just illustrate one of the present invention's design and unrestricted, under design of the present invention, any technical scheme without essence conversion is all in this patent protection domain.
