Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described further:
Technological process of the present invention as shown in Figure 1, whole technical process all is to rely on circulating air compression, the expansion refrigeration that will purify, provide degree of depth cold by Cryogenic air.Waste steel wire tyre A clean, that dried enters cool chamber 1 deep colling to-90 ℃, sends into low temperature roll-in-hammering disintegrating machine 2 and flattens through roll-in, and after the hammering fragmentation, the rubber grain separates with wirecord fabric.Is that the rubber grain of 6 millimeter blows to the adding the feed bin 4 of low temperature vortex airslide disintegrating mill 5 tops through pipeline in disintegrating machine with the high speed cold air-flow with diameter, enters in the airslide disintegrating mill from charging aperture by deadweight then.Fine glue powder comes out to import after fine glue powder storehouse 6 treats that 0.8MPa air-flow from compressor is with its cold recovery from airslide disintegrating mill below, and the temperature recovery of fine glue powder is to normal temperature, i.e. the product B of this device.
Air is compressed to 0.8MPa by air compressor 11, and drying device 10 dry backs are given cold by tail gas at cool exchanger 9, enter gas expansion refrigeration machine 8 expansion refrigerations to-105 ℃, and pressure is 0.3MPa.Be divided into two, wherein a part enters low temperature roll-in-hammering disintegrating machine 2 as low temperature in the holding chamber and coarse crushing and carry the power of micelle, deliver at the micelle that with diameter is 6 millimeters and promptly to go to cool chamber 1 that tire A is frozen to-90 ℃ after adding feed bin 4, the air self temperature recovery is behind normal temperature, getting back to air compressor 11 through filter 12 is compressed once again, another part-105 ℃, 0.3MPa air then enter low temperature vortex airslide disintegrating mill 5 micelle pulverized to behind the fine glue powder, going into cool exchanger 9 through filter 7, to give cold pressure from air compressor as tail gas be the air of 0.8MPa, and exhaust temperature goes back up to and enters air compressor 11 behind the normal temperature and compressed once again.
Account for the steel wire and the cord C of rail tyre weight 1/2nd, some rubber that do not purify of slag inclusion, in low temperature roll-in-hammering disintegrating machine, discharge as the byproduct of producing, collect in the byproduct storehouse 3, its cold is absorbed from the pressure of the air compressor air-flow by 0.8MPa, temperature recovery is to normal temperature, i.e. the byproduct of this device.Can be by hand behind the C separating device or other machineries the steel wire and the cord that flatten are dragged out again.The rubber grain that is clipped in is wherein shaken off with the way of mechanical oscillation, reclaimed, steel wire and cord also can reclaim respectively.
The air cooling of being made up of air-refrigeration system etc. is handled the device that waste steel wire tyre reclaims fine glue powder and is also comprised following three parts: low temperature roll-in-hammering disintegrating machine, low temperature vortex airslide disintegrating mill and cool chamber, wherein:
Low temperature roll-in-hammering disintegrating machine: the roller 12 that a pair of rotation is set in casing, the below of the roller 12 that rotates is provided with two pairs of hammering wheels 13,14 successively, below hammering wheel 14, be obliquely installed a vibratory sieve 15, below the hammering wheel 13,14 and vibratory sieve 15 above be respectively equipped with low- temperature airflow nozzle 16,17 and 18.Blow the rubber grain with high velocity air they and steel wire and cord are peeled off, cold airflow remains on about-90 ℃ casing internal work temperature simultaneously.
Deep colling, be the waste steel wire tyre A of glassy state, the roller 12 that is being rotated be involved in and flatten, by real, make the tire that is the concavity cross section become a real pie.Rubber is squeezed, and produces and gives stress, and internal structure begins to destroy.The tire that has flattened falls into first pair of hammering wheel inlet by deadweight, deflection when preventing from, and available trundle is arranged along falling direction and is forced tire decide direction by giving.Tire is subjected to the effect of knocking of a plurality of tups on the hammering wheel 13, and is broken and separate with steel wire, cord, continues to fall into second pair of hammering by deadweight simultaneously and takes turns 14 and enter the mouth.Between 13,14 the time, micelle is blown off by the high-speed low temperature air-flow that penetrates from nozzle 16.Tire in second pair of hammering wheel 14, be subjected to once more the knocking of a plurality of tups, broken, residual rubber is separated with wirecord fabric, continue simultaneously to fall on the slideway 19 on the vibratory sieve by deadweight, micelle is fallen for continuous time by the high-speed low temperature air-flow that penetrates from nozzle sets 17,18, through vibratory sieve, diameter is sent back to hammering greater than 6 millimeters micelle 20 by air-flow and is taken turns 13 tops.Continue broken; Diameter is delivered to adding in the feed bin of low-temperature airflow pulverizer top greater than 6 millimeters micelle 21 by air-flow, treats further powder rock; The tire shelf that only contains steel wire, cord then drops on stacking place 22 by slideway and regularly takes out.
Low temperature spiral vortex type air-flow pulverizer: as shown in Figure 3, low temperature spiral vortex type air-flow pulverizer mainly is made up of tremie pipe 1, high velocity air nozzle 23, crushing chamber 24 and clasfficiator 25 4 parts.The micelle of diameter below 6 millimeters that is glassy state flows in the Lowtemperaturepulverizer by deadweight in Feeding box.Flow out in the gap between charge pipe 1 and powder rock machine chassis, by the production capacity of adjusting play height-adjustable pulverizer.Pressure be 0.3MPa, temperature for-105 ℃ low-temperature airflow by nozzle 23 after-acceleration, the micelle that will be in greater than the angle of repose state rises, and impacts with the shock plate of arranging on crushing chamber 24 inwalls at a high speed, utilizes this percussion that micelle is pulverized; The micelle that high-speed motion is bump formation autogenous grinding mutually simultaneously.Keep operating temperature-90 ℃ in the crushing chamber.Fine glue powder (more than 60 orders) relies on the classified device 25 of inertia force to discharge.Below low temperature spiral vortex type air-flow pulverizer, import the fine glue powder storehouse.Tail gas is discharged from the top of low temperature spiral vortex type air-flow pulverizer, goes cool exchanger to reclaim cold.
Cool chamber: cool chamber places temperature to remain in-40 ℃ the shallow cold house.Waste steel wire tyre is reduced to-40 ℃ by normal temperature in shallow cold house after, enter in the cool chamber by freezing to-90 ℃ from the low temperature exhaust gas that adds feed bin.Tire is transported at a slow speed by chain plate conveyor belt in the cool chamber of tunnel type, and lifts the low temperature roll-in from ground-the stamping machine top, and the transmission device of chain plate conveyor belt is installed on outside the storehouse.
Device structure of the present invention is simple, and is easy to operate; Technology advanced person, the recovery utilization rate height; Air can be recycled, energy savings.Very easily promote the use of, can produce good economic benefit surely.
