Description
Technical field
The present invention relates to a kind of recycling method of terylene waste, and its apparatus system and equipment.
Background technology
Terylene waste is the industrial leftover pieces produced in polyester experimental branch line, is the waste material for necessarily leading to, and its yield is about
Account for the 1～2% of PET industry total output.
Substantial amounts of terylene waste is transported to the enterprise of some workshop classes at present.Water and detergent is used to process waste silk table first
The oil preparation in face, one ton of terylene waste of cleaning need the tap water using 5～10 tons.Then will be the terylene waste centrifugation after cleaning de-
Water, being put into foam material machine carries out friction pelletize, makes friction material (being commonly called as foam material).Foam material machine is generally used for plastics chemical fibre (PP/PE
Plastic sheeting, PET polyester waste silks, PET mylars, terylene, polypropylene) reclaim after pelletize, it is short that the foam material of production is used for waste spinning
Fibre, uses as low-grade products such as filling species.
Foam material machine utilizes frictional heat principle, can terylene waste directly be carried out crushing a granulating, is a kind of by terylene
Waste silk makes the plastics Aided Machine of friction material.Foam material machine, is made tight with threephase asynchronous machine as power by Belt Drive
Gu the moving knife on movable knife disc forms rotational shear with the stationary knife being fastened in pot, the thermoplastic film being put in pot can be entered
Row is crushed repeatedly, simultaneously because rotor disk rotates at a high speed, makes the plastic sheet being broken form vortex shape under the influence of centrifugal force
State, recycles the frictional heat produced between storeroom and material and pot wall material is slightly plastified, then add water it is acute cold so that
Cold granulating of material.
The current application of traditional foam material technique is primarily present problems with and defect：
1st, terylene waste cleaning, produces large amount of sewage, can cause serious secondary pollution.
During spinning, PET fiber surface will go up a certain amount of oil preparation, to smoothly complete spinning technique.So needing
Water and detergent is used to process the oil preparation on waste silk surface, one ton of waste silk of cleaning needs the tap water using 5～10 tons, and water consumption is very
Greatly.
2nd, the B values of foam material product are high, its colour changed into yellow, poor quality.
Foam material machine knife disk and terylene waste frictional heat, temperature are up to melting point polyester or so, while exposure is in atmosphere
Oxidation reaction must occur with oxygen and turn to be yellow.
3rd, degrade serious, the viscosity index of foam material declines a lot.
The frictional heat produced between storeroom and material and pot wall makes material slightly plastify, and then adds water acute cold so that thing
Cold granulating of material, polyester can occur serious water degraded at high temperature with water.
4th, foam material is low value-added.
Foam material is only used for the short fibre of waste spinning, uses as low-grade products such as filling species.

It is connected and seals with reacting cylinder body bottom, sheath body is arranged on outside bearing, and vacuum chamber is formed between bearing.3-6, vacuum chamber with it is anti-
Answer cylinder to connect, on sheath body, offer vacuum outlet port 3-7.
The rotation direction of disc-grinding mechanism is with the direction of rotation of microwave field conversely, making have relative fortune between material and microwave
It is dynamic, the microwave field of rotation at a high speed is produced, while microwave convolution antenna is set up on the mill that discharges, increases microwave in reacting cylinder body anti-
Penetrate, make material thermally equivalent, solve the problems, such as that solid terylene waste cannot uniform stirring.
Quick end cap of opening includes 4-2, flange lower cover 4-3, rotation clip 4-4, flange gate seat are covered on end socket 4-1, flange
4-5, microwave leakage-proof ring, viton seal ring, flange lower cover are welded on the open-topped upper edge of reacting cylinder body, the weldering of flange gate seat
It is connected in reacting cylinder body, on end socket, flange, lid, rotation clip weld together and pass through to rotate clip and the formation rotation of flange gate seat
Turn to open connection soon, will lock between lid and flange lower cover on flange during closing lid, the upper surface of flange lower cover has twice annular groove, micro-
Ripple leakage-proof ring and viton seal ring are respectively placed in wherein, to sealing between lid and flange lower cover on flange, anti-high pressure
And vacuum.Compressed air is filled with annular groove to placement viton seal ring, it is possible to increase sealing effectiveness.End socket is justified using cambered surface
Disk, uniform stressed can preferably avoid stress concentration phenomenon, air-tightness from being also relatively easy to be guaranteed.
The microwave purifying equipment is operated for batch type.Terylene waste is added by reacting cylinder body open top, is carried out wherein
Drying, oil removing, degraded or alcoholysis etc. are operated.
