Description
Technical field
The present invention relates to plastics machinery technical field, be specifically related to the Ni-based screw rod of a kind of novel three-stage and grind and uselessly mould modification regeneration energy-saving equipment, being mainly used in and uselessly moulding regeneration industry, wire vent has a wide range of applications in fields such as automobile, building, military affairs, lives.
Background technology
Since nineteen thirty, modern plastics industry formed, through the develop rapidly of more than 80 years, plastics industry became the mainstay of light industry.In the extensive use of plastic product, also produce huge plastic pollution, global ecological environment has been caused to great destruction.Mainly landfill disposal and burning disposal to the processing method of waste plastic garbage, but landfill disposal is because it takes up room larger, increase land resource pressure, simultaneously because useless moulding is difficult to degraded, serious obstruction the infiltration of water and underground water circulation, secondly the additive in useless moulding also can be to soil reclamation secondary pollution.Burning disposal is because CO, polycyclic aromatic compound and heavy metal that burning produces can discharge and environment is caused to very large pollution along with flue dust together with incineration residue.Along with scientific and technical progress, start to occur utilizing plastic reclaimed machinery group waste or used plastics to carry out regenerating and modifying, just in real consciousness, realize resources circulation.
At present, domestic useless correlation technique of moulding regenerating and modifying mechanical technique and developed countries is Comparatively speaking comparatively backward, and due to the increase gradually of domestic annual time-consuming generation, the degraded burden that has constantly increased the weight of the ecosystem of China, significantly improving the domestic useless regenerating and modifying mechanical technique of moulding has been the problem of having to face.Domestic existing market; the regenerating and modifying granulation machinery of waste or used plastics is more, but major part exist the regeneration stage during to modifying waste plastic the fineness of ball milling inadequate, regenerating and modifying material physicochemical property is poor; the defects such as equipment is fragile, unstable properties, have defect as follows:
1) legacy equipment structure is direct blanking, grinds, and affected by ground section depth dimensions, causes material feeding can not keep evenly, causes wire vent finished product not reach required quality requirement standard.
2) because waste or used plastics is before grinding, need to pass through crushing washing operation, plastic sheet after its cleaning is with large quantity of moisture, need to dewater to the plastics that contain moisture, just can strengthen normally modification program, otherwise, will reduce the physicochemical property of modified materials, thereby affect the capability and performance of made plastic products.In the industry of modifying waste plastic regeneration at present, the dehydration procedure carrying out for the waste or used plastics that contains moisture after cleaning, generally adopt dryer to dry, or the mode of drying under the sun is carried out dewatering operation.The defect of its existence is that dryer energy consumption is higher, and useless moulding in modification production procedure increases a link simultaneously, and its energy consumption is even more serious, has increased production cost; Dry and need the resource of employing a tremendous amount of manpower, inefficiency and waste work resource.
3) screw diameter of transmission is 159mm, and variations in temperature is fast, unstable, causes product quality also unstable.
4) in prior art, mostly be belt transmissioning mode for the transmission mechanism of screw actuator, transmission mechanism when work vibration is stronger, can drive and then vibration of screw rod, loses a part of mechanical energy, has influence on inside screw Grinding Quality simultaneously.In belt transmission, skidding is inevitable equally, causes the production efficiency of modified materials to be restricted, and the noise that belt transmission produces is large, causes noise pollution.
5) because screw rod wearing and tearing are in use very large, having it is the screw rod of regenerating device for waste plastics, uses and is just difficult to the 1-2 month using, and needs to change, and cost is high.
6) aspect the useless barrel and screw clearance of moulding modified device, 80 left and right of general processing, gap of domestic existing like product, simultaneously because screw surface treatment technology does not pass a test, screw rod easily expands phenomenon, screw flight and material tube inner wall come in contact friction, finally cause equipment normally to move.
