Description

A kind of energy-saving pelletizing module with high percentage of open area
1 technical field:
The present invention relates to a kind of pelletizing template that is used for hot melt is carried out granulation underwater.Common hot melt has PE, PP, EVA, TPEE, the transparent anti-impact resin of butylbenzene, polyamide and PUR etc.
2 background technologies:
In hot melt granulation underwater process, pelletizing template is the crucial parts of producing.Because the pelletizing template exit side immerses in the cooling water that flows, must cause heat to scatter and disappear.In the orifice plate central region, because the hot melt heat that companion's heat and discharge opening flow is enough to compensate the heat of being taken away by the cooling water that flows, so this regional temperature is basic identical, each discharge opening discharging is even.Face is at the inside and outside fringe region of orifice plate, the hot melt shortage of heat that companion's heat and discharge opening flow is to compensate the heat that the surface is taken away by the cooling water that flows, and the result causes along with close to the inside and outside edge of orifice plate, and temperature reduces gradually, the discharge opening discharging reduces gradually, even " freezing to death " not discharging.For avoiding this defective, the prior art scheme adopts the heat insulation schemes that adds heat insulating mattress, compresses heat insulating mattress by gland.But because a variety of causes such as structure and dismounting inevitably cause to have the slit that directly contacts with cooling water on the template parent at the inside and outside edge of contiguous orifice plate.The in fact most of area of heat insulating mattress that compresses by gland is in non-impaction state simultaneously, thereby can cause cooling water to infiltrate.Problems such as therefore, still there is each discharge opening discharging inequality in the heat insulating mattress heat insulation schemes, percent opening is low, pressure load is big and waste energy.
Patent US 4,378, and 964, US 4,752,196, US 4,856, and 974, US 4,678,423, US5,679,380, EP 1 413 413, DE 4 036 196, JP 8-192423, JP 10-264251, CN2456910 provide different heat insulation schemes respectively with CN2595551.The manufacturing complexity that these heat insulation schemes have; The reliability that has is low; The manufacturing process that has can not realize.
3 summary of the invention:
The orifice plate regional temperature is basic identical and be different from a kind of energy-saving pelletizing module with high percentage of open area of existing patented technology when the invention provides a kind of easy manufacturing, reliability height, template operation.
The objective of the invention is to finish with following mode:
A kind of energy-saving pelletizing module with high percentage of open area includes template parent, orifice plate; Be processed with some runners and the some extrusion cavities that communicate with it, interior companion's passage of heat on the template parent, accompany between the passage of heat, companion's thermal medium manhole appendix, some screw mounting holes, extrusion cavities and accompany the passage of heat outward; Be processed with discharge opening on the orifice plate with extrusion cavities centering; It is characterized in that being coated with certain thickness thermal insulation layer on template parent surface.
Energy-saving pelletizing module with high percentage of open area of the present invention, heat insulating mattress and interior heat insulating mattress, outer gland and internal gland outside it is characterized in that on the template parent, can arranging, outer gland and outside have the installing hole that has centering on installing hole, internal gland and the interior heat insulating mattress of centering on the heat insulating mattress.
Energy-saving pelletizing module with high percentage of open area of the present invention is characterized in that can spraying thermal insulation layer on apertured template parent surface.
Energy-saving pelletizing module with high percentage of open area of the present invention is characterized in that the template parent surface of gland and outer heat insulating mattress periphery can spray thermal insulation layer outside.
Energy-saving pelletizing module with high percentage of open area of the present invention is characterized in that the template parent surface between extrusion cavities can spray thermal insulation layer.
Energy-saving pelletizing module with high percentage of open area of the present invention, it is characterized in that interior companion's passage of heat, outside accompany the sidewall of the passage of heat can spray thermal insulation layer.
Energy-saving pelletizing module with high percentage of open area of the present invention is characterized in that can spraying thermal insulation layer at the screw mounting hole sidewall.
Orifice plate can be spliced by some fanning strips; The fanning strip material is an anti-friction material; Orifice plate and template parent adopt soldering to be solidly fixed.
Orifice plate also can be made for stainless steel material; On orifice plate, arrange paxilla and little cylindrical shell by anti-friction material processing; But little cylindrical shell endoporus double as discharge opening of while; Orifice plate, template parent, paxilla and little cylindrical shell adopt soldering to be solidly fixed.
Orifice plate can be realized by the anti-friction material powder is sprayed on the template parent, be processed with the discharge opening with extrusion cavities centering on it.
The thermal insulation layer material is the material that the coefficient of heat conduction is low, high temperature resistant and do not chap.
Typical case's insulating layer material is a zirconia.
Thermal insulation layer can be realized by spraying methods such as vacuum coating, plasma spray coating, supersonic spray coatings with the mode of fixedlying connected of template.
Typical case's anti-friction material has titanium carbide, Cr-Ni-W alloy and tungsten carbide etc.
Orifice plate thickness is 1~5mm.
It is as follows that this energy-saving high open-ratio granulating is touched plate groundwork principle:
After the hot melt that has a certain pressure flows through runner, extrusion cavities and discharge opening on the template parent successively, in the cooling water that flows, be cut into particle by the rotary cutter that fits together with the orifice plate exit side.
Because the existence of thermal insulation layer, the whole regional temperature of orifice plate is basic identical during the template operation, and all discharge opening dischargings evenly, template percent opening height, pressure load be low; Heat scatters and disappears less, saves companion's heat energy simultaneously, the cooling water heat load is low.
The present invention has following characteristics:
1. each discharge opening discharging evenly, template percent opening height, pressure load be low;
2. heat scatters and disappears less, saves companion's heat energy, the cooling water heat load is low;
3. simple in structure, easy to manufacture, reliable.
