Abstract
The utility model relates to a charging barrel quartz pipe heating ring, which comprises a circular quartz heating pipe bundle 4, circular pipe plates 5, an inner sleeve 3, an outer sleeve 1, circular end covers 6 and a heat insulating layer 2, wherein, the circular pipe plates 5 are fixedly connected with both ends of the circular quartz heating pipe bundle 4, the inner sleeve 3 is sheathed outside the circular quartz heating pipe bundle 4, the outer sleeve 1 is sheathed outside the inner sleeve 3, the circular end covers 6 are covered to both ends of the circular pipe plates 5, and the heat insulating layer 2 is embedded between the inner sleeve 3 and the outer sleeve 1 and also between the circular pipe plate 5 and the circular end cover 6. The heating ring has less heat loss and high thermal efficiency which reaches to above 90 percent; the needed pre-heating time of a screw extruder can be reduced from the original 2 to 2.5 hours to 40 minutes by now; the production efficiency is greatly increased; moreover, the raw material cost of the quartz pipe heating ring is low, and the weight is light.
Description
Technical field:
The utility model relates to a kind of barrel quartz ampoule heating collar.Be mainly used in the heating of the barrel of screw extruder, injection machine etc.Belong to the plastics machinery technical field.
Background technology:
Screw extruder, injection machine etc. are mainly used in the heat fused of plastic pellet and extrude.Plastic pellet in its barrel is to come heat fused by being set in the outer heating collar of barrel.Traditional heating collar is an aluminium alloy system.Form by aluminium alloy sleeve barrel and the heating wire that is embedded in the sleeve.Heating wire energising back heating aluminium alloy sleeve barrel, aluminium alloy sleeve barrel conducts heat to the screw extruder barrel again.On the one hand, the aluminium alloy heating collar does not have the insulation measure, and thermal loss is many, and it is slow to conduct heat, and the thermal efficiency is low, only is about 60%; Screw extruder is required, and to preheat the time long, was generally 2～2.5 hours, and production efficiency is lower.On the other hand, aluminium alloy heating collar cost of raw material height, Heavy Weight.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of thermal efficiency height, barrel quartz ampoule heating collar that the cost of raw material is low are provided.
The purpose of this utility model is achieved in that a kind of barrel quartz ampoule heating collar, comprise ring-type quartz heating-pipe bundle, ring-type tube sheet, interior cover, overcoat, ring-type end cap and insulating, the ring-type tube sheet is fixedly connected on ring-type quartz heating-pipe bundle two ends, interior being placed on outside the ring-type quartz heating-pipe bundle, outside overlapping in overcoat is placed on, ring-type end cap lid places ring-type tube sheet two ends, insulating to be embedded between interior cover and the overcoat and between ring-type tube sheet and the ring-type end cap.
Because quartz heating-pipe of the present utility model is provided with insulating outward, on the one hand, thermal loss is few, and thermal efficiency height can reach more than 90%; The time that preheats that screw extruder is required can be reduced to about 40 minutes by original 2～2.5 hours, and production efficiency improves greatly.On the other hand, the quartz ampoule heating collar cost of raw material is low, and is in light weight.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cut-away view of Fig. 1.
Fig. 3 is the right side view of Fig. 1.
The specific embodiment:
As Fig. 1～3, the utility model is a kind of barrel quartz ampoule heating collar.Mainly form by ring-type quartz heating-pipe bundle 4, ring-type tube sheet 5, interior cover 3, stainless steel outer sleeve 1, ring-type end cap 6 and asbestos insulation heat-insulation layer 2.Ring-type tube sheet 5 is fixedly connected on ring-type quartz heating-pipe bundle 4 two ends, interior cover 3 is placed on outside the ring-type quartz heating-pipe bundle 4, overlap outside 3 in stainless steel outer sleeve 1 is placed on, ring-type end cap 6 lids place ring-type tube sheet 5 two ends, asbestos insulation heat-insulation layer 2 to be embedded between interior cover 3 and the stainless steel outer sleeve 1 and between ring-type tube sheet 5 and the ring-type end cap 6.
