As shown in Figure 1: a kind of efficient scratch system, comprise vacuum feeder 1, hopper 2, vibration feeder 3, charging aperture 4, buhrstone mill 5, conveying pipeline road 6, cyclone separator 7, Blowing stopper 8, vibratory sieve 9, material receiving port 10 and air-introduced machine 11, vacuum feeder 1 is connected with hopper 2 by antistatic enhanced plastic flexible pipe; Hopper 2 is connected with vibration feeder 3 by bearing; Charging aperture 4 is directly installed on the buhrstone mill 5; Buhrstone mill 5 outlets are connected with conveying pipeline road 6; Conveying pipeline road 6 ends are connected with cyclone separator 7 by flange; Cyclone separator 7 exhaust outlets are connected with air-introduced machine 11 by pipeline; Cyclone separator 7 feed openings are connected with Blowing stopper 8 by flange, visor; Blowing stopper 8 is connected with vibratory sieve 9 by blanking reducing pipeline; The outlet of vibratory sieve 9 accepts is over against material receiving port 10; Vibration feeder 3 other ends are connected with charging aperture 4; Also comprise desiccant dryer 12, described desiccant dryer 12 is installed in the air inlet of buhrstone mill 5 by adpting flange.
Described flour mill 5 is provided with fan blade 5-1, and described fan blade 5-1 is fixedlyed connected with the mill main shaft by bolt 5-2.Described conveying pipeline road 6 and cyclone separator 7 peripheries are equipped with water-cooling jacket, form cooling chamber between described conveying pipeline road 6 and cyclone separator 7 and the water-cooling jacket.Described Blowing stopper 8 is 7 liters/commentaries on classics block-resistant type bearing external Blowing stopper.
During concrete enforcement, desiccant dryer 12 is installed in the air inlet of buhrstone mill 5 by adpting flange, the size of fan blade 5-1 is set by the specification of flour mill 5 in the middle of the mill, be that fan blade 5-1 is fixedly connected by the bolt 5-2 on the mill main shaft, set the cooling jacket on conveying pipeline road 6 according to the diameter on conveying pipeline road 6, set the cooling jacket of cyclone separator 7 according to the diameter of cyclone separator 7, by adopting wind, water is two cold, utilize the cooling of cooling jacket of the water-cooling jacket on conveying pipeline road 6 and cyclone separator 7 and the cooling of mill fan blade 5-1, reduced the operating temperature in the body preferably, guaranteed the stability of PETG material: temperature is not high, viscosity is little, the material that grinds is mutability not; By changing block-resistant type Blowing stopper 8, employing blanking amount is bigger, the bearing external Blowing stopper 8 of special rotor, and according to the interface size of Blowing stopper 8, enlarge the feed opening of cyclone separator 7 and the feed opening of Blowing stopper 8, powder can not wadded a quilt with cotton in cyclone separator 7 and be gathered, lumps like this, and powder can not block the bearing of Blowing stopper 8, has guaranteed the smooth and easy of blanking, reduce the generation of ramming material, improved total quality and the working (machining) efficiency of product.
Blowing stopper 8 in this device changing 7 liters/commentaries on classics into by 2.8 liters original/commentaries on classics, changes block-resistant type bearing external into by plain edition.
Draw by above-described embodiment and the utlity model has following advantage:
One, the PETG glass transition temperature only is 86 ℃, when the abrasive dust temperature is high, causes the abrasive dust cutter sticky, the ramming material phenomenon occurs, and powder is poly-, the caking of wadding in cyclone separator easily, influences grinding speed and milling quality.The present invention adopts water-cooled (flour mill housing water-cooled, material pipe, cyclone separator water-cooled) and air-cooled (the inner employing of flour mill is air-cooled) mode, guarantees that the abrasive dust temperature keeps low-temperature condition below 60 ℃.
Two, owing to contain ester group in the PETG macromolecular chain, hygroscopicity is arranged, if the existence of moisture is arranged in the polyester, during heating and melting, because moisture evaporation can produce a large amount of bubbles, influence the product apparent property; Simultaneously, PETG is backbone, even there is the moisture of trace to exist, can cause molecular chain rupture during fusion, molecular weight and molecular weight, and the product qualitative change is bad.Therefore, install desiccant dryer additional at the flour mill air inlet, air intake drying when as far as possible keeping abrasive dust.
Three, viscosity is big during PETG high temperature, causes the abrasive dust cutter sticky, the ramming material phenomenon occurs, powder poly-, the caking of wadding, not blanking in cyclone separator easily.Fine powder material enters the Blowing stopper bearing chamber easily when using the plain edition Blowing stopper, just can by changing the block-resistant type Blowing stopper, adopt the bearing external Blowing stopper means of special rotor to problems such as bearing block in the short time, reaches blanking effect smoothly.
The utility model also can be used for the abrasive dust of particulate material such as PVC, PET simultaneously, and the field is widely used.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
