Abstract
The utility model relates to an online cooling system of an internal surface of polyolefin pipes. The online cooling system of the internal surface of the polyolefin pipes comprises a mould for producing the polyolefin pipes, an air conduit and a draught fan, wherein the draught fan is connected with an inner air flue and an outer air flue of the mould through the air conduit, and the air conduit is also connected with a hot air drying hopper on production lines of the polyolefin pipes. Compared with the prior art, the online cooling system of the internal surface of the polyolefin pipes has the advantages of saving energy consumption and improving quality and quantity of products and being used widely and being safe and reliable.
Description
Technical field
The utility model relates to cooling system, especially relates to the online cooling system of a kind of polyolefin pipe inner surface.
Background technology
Current, in the polyolefin pipe process of manufacture, existing tubing cooling system only through with the form of cool water shower or dipping bath pipe outer surface being cooled off, only cools off by nature and tubing is inner.Because the heat-conductive characteristic of plastics is poor; This type of cooling can not be cooled off the tubing materials inside fast; Thereby be prone to produce molten hanging down and cause greatly on the big model tube wall thickness that lower deviation is big, internal surface of pipe has burnt material situation, tubing circularity is not high, produce crooked, cooling effectiveness is low, needs to increase more cooling device; Cause the polyolefin pipe production line long, the workshop is put difficulty and is caused lot of energy and the shortcoming and the problems such as waste of water resource.
Summary of the invention
The purpose of the utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of energy-saving and cost-reducing, improve product yield and quality, be widely used, the safe and reliable online cooling system of polyolefin pipe inner surface.
The purpose of the utility model can realize through following technical scheme: the online cooling system of a kind of polyolefin pipe inner surface; Comprise the mould of producing polyolefin pipe; It is characterized in that; Also comprise ventilation shaft and blower fan, described blower fan connects the interior air channel and outer air channel of mould through ventilation shaft, and described ventilation shaft also connects the heated-air drying hopper on the polyolefin pipe production line; The air that fan starting, the hot-air that polyolefin pipe is inner interior air channel through mould and outer air channel are formed flows and extracts out in the air channel, reduction polyolefin pipe temperature inside, and hot-air introduced the heated-air drying hopper of production line, heat drying raw material.
Described ventilation shaft is connected to form by straight tube, flange and elbow.
Described ventilation shaft is provided with thermal insulation layer outward.
Described blower fan is installed on the blower fan seat.
Compared with prior art, the utlity model has following advantage:
One, energy-saving and cost-reducing: as in the polyolefin pipe production process, to use this inner surface cooling system, can reduce the spray equipment on the production line, can shorten production line cooling length 40%, save mass energy consumption.And, substitute the heater of hot-air drying device with the heated-air drying hopper on the hot-air introducing production line of interior pipe extraction.Saved the required energy consumption of raw material drying.
Two, improve product yield and quality: this inner surface cooling system can make extruder output improve 60%; Improve polyolefin pipe inner surface fineness, remove phenomenons such as burnt material, ripple; Improve polyolefin pipe circularity; Improve molten hanging down, reduce the tube wall thickness deviation.
Three, be widely used: this inner surface cooling system can be applied in the thick-wall tube production line of caliber 250～2400mm, and main specifications has
polyolefin pipe production lines such as
.
Four, simple to operate: as when using this inner surface cooling system, to regulate air cooling system, reach best cooling effect, guarantee the tubing quality of production.
Five, safe and reliable: the ventilation duct design height does not influence the production line routine operation in this invention, and ventilation duct has thermal insulation layer outward, prevents to scald.
