Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing.
Anhydrous useless renovation process of moulding is exactly undertaken giving up moulding to regenerate by disposable technique replacement WATER-WASHING METHOD being processed into qualified particle, pp material such as various waste and old plastic woven bag, cement are moulded regeneration such as compiling packaging bag by disposable technique and are processed into plastic grain by this production method, or polyethylene raw material such as various waste and old plastic film regeneration are processed into and mould grain.
Next introduce anhydrous giving up of the present invention by specific embodiment and mould renovation process, it mainly comprises fragmentation, removal of impurities, dust suction, separation, granulation, pelletizing, packaging and other steps, and details are as follows for concrete steps:
One, broken, removal of impurities
Raw material fragmentation is carried out in disintegrating machine, and the raw material after fragmentation falls assorted through gravity removal of impurities, magnetic force removal of impurities, sawing sheet removal of impurities and inertia successively, then carries out the step of dust suction, separation.Concrete steps are as follows:
First waste or used plastics raw material is transported to workshop from storehouse, then feeding is to conveyer 1, by conveyer belt running and enter disintegrating machine 2 after magnetic inspection, after fragmentation, enter the blanking processor 3 being arranged on disintegrating machine 2 bottom carry out gravity removal of impurities, by the speed of regulating shaft to blowing in blanking processor 3, overcome the interference of turning round wind in blanking processor, make lighter useless block of moulding to axial operation, and not sedimentation is blocked, stone simultaneously, cement block, grit, spill from the assorted mouth that falls of the bottom of blanking processor after the heavy foreign material sedimentation such as metal object, the assorted mouthpiece that falls is gradient, thus heavy foreign material can utilize gradient to skid off voluntarily, realize the removal of impurities of first gravity.
Material after fragmentation enters magnetic force trash separator 4 by blanking processor 3, and that does not remove in blanking processor uselessly moulds the much the same metal sundries of block weight, under the effect of magnetic force, falls, adsorbed and carry out clearing up and collecting from the bottom sedimentation of magnetic force trash separator 4.Then, material, through filter 5, by filter screen by clean for the impurity filter being less than 5mm, realizes second removal of impurities.
Material through second removal of impurities enters cutting machine 6, under the quick machinery repeatedly strike of cutting machine and the comprehensive function of wind-force, the useless attachment, sand and dust, earth etc. moulded on block comes off, and skids off voluntarily from the inclined-plane of the dust fall plate of the bottom of cutting machine, realizes third time removal of impurities.Enter inertia through the material of three removal of impurities to fall assorted device 7, remove remaining impurity.
Two, dust suction, separation
Dust and material to be carried out first time by dust catcher and are separated by the material after broken, removal of impurities, and the mass transport for the first time after separation is to feed bin; Carried out second time with partial material through cyclone separator by the dust of dust catcher sucking-off to be separated, the material after second time is separated through separator by satisfactory for size feed separation to collection box, and flow to feed bin in order to granulation.Concrete steps are as follows:
Material after the 4th removal of impurities-inertia falls to mixing enters dust catcher 8, dust and material is carried out first time to be separated, and is separated clean material and is delivered to feed bin 14, in order to granulation by feeder 9.
Enter cyclone separator 10 and carry out second time through the dust of dust catcher 8 sucking-off and the broken silk of moulding of part and be separated, dust and the tiny silk of moulding of trace fall into from cyclone separator and connect dirt bag.And separate from cyclone separator 10 brokenly mould silk and micronic dust enters separator 11, through third time be separated will be greater than 100 objects totally broken silk of moulding all reclaim and enter collection box 13, prepare against granulation by conveying device automatic transport to feed bin.
Through the isolated atomic dirt of separator 11 (superfine dust) after dust arrester filters, automatically enter and connect dirt bag.Filter clean air to meet environmental requirement and then discharged outside workshop by main air blower 12 after test.
Three, granulation, pelletizing, packaging
Granulation comprises three grades of granulation modes, is respectively at the first granulator heating, to heat and filter residue and production granulation in the 3rd comminutor at the second comminutor again, produces produce qualified and mould silk and to weigh after pelletizing packaging from the 3rd comminutor.Specific as follows:
The clean plastic wire block meeting granulation conditions in feed bin 14 sends into feeding machine 16 through Material sucking machine 15; feeding machine 16 is with the speed of coupling and the mode by mechanical pressurization; siccative is moulded uniformly a block and feed the first comminutor 18; feeding machine 16 is provided with feeding machine circulating fan 17, can circulation return air to feed bin 14.A block of moulding after the first comminutor 18 heats is admitted to the second grain-making machine 19; after heating filter residue again, the 3rd comminutor 20 is entered in the second comminutor; produce from the 3rd comminutor 20 silk of moulding produced and enter cooling bath, packaging of weighing after eventually passing pelleter 21 pelletizing.
The present invention without the need to washing, dry process produce can process clean, meet granulation conditions mould a block, and without sewage discharge, meet environmental requirement.Production system of the present invention is negative-pressure sealed operation.Workshop does not have flying dust and pollutes, and discharges air multistage filtering separation, discharges, free of air pollution through dust arrester.The present invention because of without the need to washing, northern severe winter can be produced as usual, realize all-weather produce.The each operation of the whole production process of the present invention is automation closed operation, except artificial toward except conveyer belt feeding, basic prosthetic work, alleviate labour intensity, decrease the amount of labour used, solve on-the-spot pollution, improve useless working environment and the industry image moulding regeneration industry of tradition, improve industry self-confidence and self-esteem.Flow process of the present invention is short, and equipment is simple, and running is reliable, and cost is low, and system unit-hour output is high, and siccative is broken, siccative granulation power consumption low (compared with former WATER-WASHING METHOD), and production efficiency is high, and unit cost reduces.The rate of recovery of the present invention is high, and Plastic is substantially lossless, also therefore non-pollutant discharge.The grit of discharging respectively when producing with bag of cement and cement flour all can distinguish reuse again or back to nature.
The present invention be instead of by the mode that physics is broken apart and pollutes water-washing method that is heavy, complex process, and existing plant equipment can be utilized to carry out processing, and equipment investment fund is lower, extensively can be adopted by medium-sized and small enterprises.
Present invention process is mature on the whole, after repetition test, test, test manufacture, again improving, the high-volume actual production of model machine production system, product quality reaches purpose of design (exceeding washing material), production capacity can reach 800kg in one hour, and production capacity meets or exceeds theoretical yield.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
