Abstract
The utility model discloses an underwater pelleting device which comprises a pelleting molding board, a cutter, a pelleting quenching groove, a cooling groove for pelleted product. The pelleting molding board is made heat trace by a heat resource and is provided with a plurality of pelleting holes; the flowing cooling water is filled in the pelleting quenching groove, the exit sides of the pelleting holes on the pelleting molding board and the cutter are dipped into the flowing cooling water in the pelleting quenching groove. The pelleting process is as follows: the rotary cutter pellets the hot-melt bodies extruded from the pelleting holes on the pelleting molding board, the pelleted product is shrunken into a quasi-spherical shape in the flowing cooling water in the pelleting quenching groove, then the pelleted product is conveyed by the flowing cooling water to the cooling groove for pelleted product to further be cooled to an internal temperature below the softening point, and the dehydration is made in the successive working section when the temperature requirement is reached. The utility model can shape low softening point high adhesive hot-melt bodies such as hot-melt adhesive and so on, into quasi-spherical shaped particles.
Description
Technical field:
The utility model relates to a kind ofly can be high temperature the low softening point material that flow regime, normal temperature are solid state, is shaped to the granulation underwater device of torispherical particle as PUR etc.
Background technology:
Chinese patent (the patent No.: 98 2 44552) provided a kind of hot melt prilling granulator, although to low viscosity (＜2000cp) elevated temperature heat melt such as PUR can carry out granulating and forming, but because the PUR heat transfer is poor, cooling difficulty on the cooling steel band, granulation yields poorly.For high viscosity (＞3000cp) the high sticking hot melt of low softening point such as PUR can not granulating and forming, because such hot melt adhesion prilling head produces the wire drawing phenomenon.
Summary of the invention:
The purpose of this utility model provides that a kind of shaped granule is regular, the granulation underwater device of granulation output height, non-environmental-pollution, and it is specially adapted to low softening point elevated temperature heat fused mass granulating.
The purpose of this utility model is finished with following mode: include pelletizing template, cutting knife, granulation quench tank, pelletizing product cooling bath; Pelletizing template has some granulations hole by thermal source companion heat on it; It is characterized in that granulation hole exit side and cutting knife are in the granulation quench tank on the pelletizing template, granulation hole exit side end face enters the mouth with pelletizing product cooling bath and communicates with cutting knife cutting edge vertical range 0.02--0.2mm, the outlet of granulation quench tank.
The utility model has following advantage:
1. granulation output height.
2. shaped granule is torispherical, regular, not wire drawing, adhesion.
3. there is not dust, non-environmental-pollution
Description of drawings:
Fig. 1 is a granulation underwater device schematic diagram
The specific embodiment:
The purpose of this utility model is finished with following mode:
Include pelletizing template 1, cutting knife 3, granulation quench tank 4, pelletizing product cooling bath 5; Pelletizing template 1 has some granulations hole 2 by thermal source companion heat on it; It is characterized in that granulation hole 2 exit sides and cutting knife 3 are in the granulation quench tank 4 on the pelletizing template 1, granulation hole 2 exit side end faces enter the mouth with pelletizing product cooling bath 5 and communicate with cutting knife 3 cutting edge vertical range 0.02-0.2mm, 4 outlets of granulation quench tank.
Granulation process is as follows: pelletizing template 1 is preheating to prilling temperature, fill in the granulation quench tank 4 and make with the cooling water that flows that granulation hole 2 exit sides immerse in the mobile cooling water with cutting knife 3 on the pelletizing template 1, adjusting granulation hole 2 exit side end faces and cutting knife 3 cutting edge vertical ranges is 0.02--0.2mm, starting the cutter driving system makes cutting knife rotate with certain speed, starting feeding system makes hot melt be extruded by the mobile cooling water side of 2 immersions of granulation hole on the template 1, the extruding and hot melting body is by the cutting knife pelletizing that rotatablely moves, pelletizing product 6 is punctured into torispherical in the cooling water that flows, pelletizing product 6 is transported in the pelletizing product cooling bath 5 by mobile cooling water and is further cooled off by cooling water then.Pelletizing product 6 is fully cooled off, is treated to go after internal temperature drops to below the softening point dehydration of follow-up workshop section in pelletizing product cooling bath 5.
Claims (1)
