Abstract
The utility model relates to a granulator for the plastic waste of polyolefin and the powder materials. The granulator belongs to water cooling granulators for polyolefin plastics, double supporting threaded rods are adopted in a water cooling type, and a water cooling device of the granulator can be regulated according to output. The utility model has the advantages of low cost, small ground occupation, energy saving and easy operation.
Description
The utility model relates to a kind of TPO powdery (waste material) comminutor.
At present, external existing TPO powdery (waste material) comminutor has the airtight underwater pelletizer under water fully of complete machine.This comminutor is with a whole set of online use of chemical industry polymerization unit.Domestic have an air-cooled comminutor, belong to unit, but cooling effect is undesirable, yields poorly.
The utility model is to take water-cooling method, makes the unit of polyolefin powdery (waste material) granulating, from structure, be similar to the waste wood recovery machine (GRA60 type) that Austria produces, but the discharge of the waste recovery machine cooling device that Austria makes can not be controlled.From the polyolefin plastics prilling, have only the particle of maintenance to be cooled to just can make particle light, epigranular about 40 ℃.Discharge is too big, and particle shrinks, and is uneven, rough surface; Discharge is too little asynchronous with output, should take measures the flow of control cooling water.
The waste recovery machine screw rod that Austria produces is single supporting, and just the feed end of screw rod matches with the extruder main shaft, and discharge end can only lean on extruder barrel to support naturally.It is sagging because the screw rod deadweight produces amount of deflection.When screw rod rotated, screw rod and machine barrel produced friction, the thorax phenomenon occurs sweeping, influence the service life of screw rod.Because the screw rod distortion produces pulsating nature, can influence the plasticizing quality of material.
The purpose of this utility model is that a kind of improved polyolefin powdered plastic prilling granulator will be provided.It can regulate cooling water flow according to the output of comminutor; Adopt the double base screw rod to prevent that screw rod is out of shape the plasticizing quality that produces pulsating nature and influence material, thereby reach the prolongation service life of equipment, improve the purpose of granulation quality.
The purpose of this utility model is achieved in that establishes a taper roller bearing on the extruder screw discharge end diameter of axle, this bearing one end links to each other with the screw rod diameter of axle, and the other end is fixed on the support.And discharge end is installed near extruder transmission main shaft one side, and feed end is at opposite side, and is opposite with common extruder.Like this when the powdery vistanex after feed arrangement enters extrusion system, material fusion under extrusion pressure and temperature action, because screw rod is a double base, reduced the possibility of screw rod distortion generation pulsating nature under the extrusion pressure effect, and can make the abundant fusion of material, again because the screw rod of this device is a form of taking upside-down mounting, from the expressing technique angle, adjust like this and equal correspondingly to have strengthened spiral groove depth, can improve complete machine output, material arrives machine head port mould through net-changing device after the extrusion system fusion, cut into particle.Particulate material is cooled to finished product via the trickling cooling plant that holds hydroecium and spray-hole composition.Hold the water pump of the water of hydroecium, can adjust by comminutor output incessantly and be arranged on water pump and the valve that holds on the hydroecium pipeline, supply water, spray to particle by spray-hole and make it cooling to holding hydroecium from 17 meters of lifts.
The utility model is cooled to 40 ℃ ± 2 ℃ optimum condition to keep particle, thereby guarantees granular mass because of only need regulating discharge according to comminutor output by adorning a valve on pipeline between supply-water pump and cooling device appearance hydroecium; Only need make the screw rod double base, just can avoid because of the screw rod distortion, sweep the drawback that thorax generation pulsating nature influences service life of equipment and plasticizing quality, thus simple in structure, be easy to realize.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a polyolefin powdery comminutor unit concrete structure view;
Fig. 2 is the cutaway view of Fig. 1 along the A-A line;
Describe concrete device details of the present utility model and working condition in detail below in conjunction with Fig. 1 Fig. 2.
This device is the extrusion system 1 by a plastifying material, this extrusion system comprises that material is carried out mixing, pressurization extrudes the screw rod 16 and the machine barrel 17 of effect, support plinth 2, feed arrangement 3, electrical equipment control screen 4, cooling blower 5,13,14, commutator machine 6, the control screw rod is the main frame transmission system 7 of rotating speed, moment of torsion Rotating with Uniform on demand, net-changing device 8, cooling device 9, water pump 10, vibratory sieve 11,12, the taper roller bearing 19 of standing screw feed end, the main hollow spindle of standing screw discharge end hold 18 and the valve 20 of control cooling water flow form.
Powdery (or waste material) vistanex enters extrusion system 1 through feed arrangement, and extrusion system is made up of screw rod 16 and machine barrel 17, and material is passed forward under the rotary screw effect, and at 215 ℃ ± 5 ℃ of extrusion temperatures, extrusion pressure 300kg/cm
2Under the effect, material becomes the fusion viscous state.The screw feed end is connected with main hollow spindle 18, taper roller bearing 19 connecting screw rods of establishing on discharge end and the diameter of axle are inverted with extruder is opposite usually, do the double base effect that has not only reached screw rod like this, make screw rod and machine barrel keep concentricity, from the extruding-out process angle, the inversion of screw rod equals correspondingly to have strengthened the degree of depth of screw channel, helps improving extruding output.Become the fused materials of viscous state, the net-changing device 8 of flowing through arrives the die orifice pelletizing.Cut particle is through cooling device 9 typings.The water pump of the water of hydroecium from 17 meters of lifts formed, held to cooling device by holding hydroecium and spray-hole.Owing to be provided with valve 20 on the pipeline between water pump 10 and the cooling device 9, can regulate cooling water flow according to granulation output, make particle keep being cooled to 40 ℃ ± 2 ℃ optimum temperature, smooth, even with the assurance particle.Particle behind the cooling and shaping is sent into vibratory sieve 11,12 under flow action, carry out that water particle separates and oven dry, through pressure fan 5,13,14 particle is imported material-storage jar 15 again, seals up for safekeeping stand-by.
Whole process flow is:
Powdery (waste material) resin---is extruded---Qie La---cooling and shaping (injection)---separation (oven dry)---basin storage.
