Description
Technical field
The present invention relates to a kind of carpet back-adhesive tearing-off (CaCO
3Mixture with SBR butadiene-styrene rubber) method the invention still further relates to the equipment that is exclusively used in this method.
Background technology
The recycling of waste carpet is whole world government and environmental administration's issue to be resolved always, and the recycling difficult problem of waste carpet mainly is exactly will be with fiber and gum (CaCO
3Mixture with SBR) breaks away from.
Carpet generally is by knitting the fiber on the PP braid over braid, the PP net of bottom, middle CaCO
3Form with the mixture of SBR.CaCO
3With the mixture of SBR be to be bonded at fiber U type root fully.This brings very big difficulty to reclaiming fiber useful in the carpet.
A lot of companies have all done a large amount of research in this respect, but still do not have good solution so far.Disclosed as the Chinese patent communique, by Dutch DSM N. V. 1996 patent of invention " from contain the nylon refuse, reclaiming the method for caprolactam " in China's application, publication number CN1196048, it mainly solves from contain the nylon refuse from the method for chemical depolymerization and reclaims caprolactam.The investment of this method is big, and economic benefit is also not obvious.
Existing with carpet fiber and CaCO
3, the mixture of the SBR method of sloughing mainly contains two kinds, the one, will with chemical solvent SBR be dissolved away after the carpet fragmentation, water washes CaCO again
3, this method is very big to the pollution of environment, can not promote.Another kind method is exactly with the scissors of sheepshearing the fiber on the carpet to be cut off, and the treatment effeciency of this method and the rate of recovery are all low, and output is also very little.
Summary of the invention
First technical problem to be solved by this invention, just provide that a kind of investment is little, treatment effeciency and rate of recovery height, the method that can simply and effectively carpet fiber and the gum that is bonded at the fiber root be broken away from, gum is transformed into the object of powdery by this method, and the fiber on the carpet also keeps the original length constant substantially, is convenient to both and separates easily.
The method step of carpet back-adhesive tearing-off of the present invention is as follows:
1) the good carpet of will classifying removes bottom PP net bottom;
2) carpet that will remove the PP net bottom by the active drawing-in device of the cylinder of pressing being formed by a group will be stained with gum one side hello to the abrasive machine emery wheel, emery wheel is ground to powdery with gum or gum and part PP braid over braid.
In the above-mentioned steps:
One group of described active drawing-in device is respectively initiatively and driven cylinder pressure roller, and the grinding face of drive roll and abrasive machine emery wheel is less than or equal to 10mm apart from more than or equal to 2mm.
The pressing wheel device that described carpet also is provided with the band cylinder after by the grinding just of abrasive machine emery wheel overlays on abrasive machine wheel grinding face carpet further, and grinding becomes powdery fully up to gum, the grinding face distance of the cylinder of pressing wheel device and abrasive machine emery wheel is less than or equal to 10mm more than or equal to 2mm.
The difference of described abrasive machine wheel grinding speed and carpet rate of feeding is more than or equal to 500 meters/minute, be less than or equal to 2500 meters/minute, described abrasive machine emery wheel is preferably silicon carbide material, have pore, the abrasive machine grinding wheel speed is more than or equal to 500 rev/mins, be less than or equal to 2500 rev/mins, the overall diameter of emery wheel is less than or equal to 600mm more than or equal to 200mm.
The method advantage of carpet back-adhesive tearing-off of the present invention:
1, compare with the scissors of sheepshearing the fiber on the carpet is cut off the method for getting off, processing method of the present invention is more effective, has improved processing speed greatly.
2, compare the method for using organic solvent dissolution SBR, the complete environmental protection of the present invention does not produce secondary pollution.
3, the present invention is simple to operate, and fault rate is low, realizes automated production easily.
This method efficiently solve over perplex always people for many years slough CaCO in the carpet
3With the difficult problem of SBR mixture, to the landfill that reduces carpet and carpet has been reclaimed very big impetus.
Certainly, the present invention is a link in the carpet recovery system, the various material in the carpet is spun off fully, becomes reproducible resource, also to just can reach through other processing procedure,
Second problem to be solved by this invention provides a kind of equipment that is exclusively used in the method for above-mentioned carpet back-adhesive tearing-off:
On frame, be provided with abrasive machine, drawing-in device and pressing wheel device, described drawing-in device comprises: the active and driven two cylinders that are provided with the parallel and mutual applying of rotating shaft in a frame supported seat, drive roll is fixed and is pressed close to the abrasive machine emery wheel, and driven cylinder is slidably supported on the guide rail of supporting seat and is provided with spring compression mechanism by bearing pushes driven cylinder to drive roll; Described pressing wheel device is: be provided with the cylinder that rotating shaft is parallel to the abrasive machine grinding wheel spindle in a frame supported seat, the cylinder of pressing close to the abrasive machine emery wheel is slidably supported on the guide rail of supporting seat and is provided with the spring compression position-limit mechanism by bearing pushes the pinch roller cylinder to the abrasive machine emery wheel to certain spacing.
The T profile shaft that described driven roller bearings is a prior art holds, and mechanism of described spring compression mechanism is: the T profile shaft holds and is provided with slide bar, in the middle of the slide bar compression spring is housed, and the slide bar end passes the pilot hole of frame supported seat.
