Abstract

The invention discloses an energy-saving type melt pipeline and a manufacturing method. The energy-saving type melt pipeline comprises a chrome molybdenum alloy pipeline with the smooth inner wall, a heating device is installed on the outer surface of the chrome molybdenum alloy pipeline, and a heat preservation layer is installed on the outer surface of the heating device. The outer surface of the chrome molybdenum alloy pipeline is evenly wound by the heating device, and the heating device is a stainless steel heating wire. The manufacturing method comprises the steps that a chrome molybdenum alloy pipeline material is adopted; firstly, the surface of the chrome molybdenum alloy pipeline material is polished; secondly, hard chromium plating is carried out on the polished chrome molybdenum alloy pipeline material; thirdly, the chrome molybdenum alloy pipeline material on which hard chromium plating is carried out is manufactured into the chrome molybdenum alloy pipeline with the pressure-resisting value reaching to 50 MPa; fourthly, the outer surface of the chrome molybdenum alloy pipeline is wound by the stainless steel heating wire; lastly, the outer surface of the chrome molybdenum alloy pipeline wound by the stainless steel heating wire is wrapped by the heat preservation layer. The energy-saving type melt pipeline has the advantages of being easy to bend, even in heating and small in heat loss.

Description

A kind of energy-saving melt pipe and making method
Technical field
The present invention relates to plastic melt conveying technology field, relate in particular to a kind of energy-saving melt pipe and making method.
Background technique
At present, plastic melt conveyance conduit generally only has following a kind of form:
Be that 45# steel punching is made, outer surface adopts a plurality of mica heating collars heating, and without any the runner of insulation safety measure.
This runner is when melt Conveying; because the density degree of mica heating collar parcel is different; there will be temperature sampling inaccurate; and skin do not have heat insulation protecting measure, can cause like this distribution loss of heat, also can cause the danger of scald; especially independently bending when pipeline needs bending; the elbow that need to install specified angle additional is realized turning, is uneconomical not energy-conservation way, and inadvisable.
Summary of the invention
The invention provides a kind of energy-saving melt pipe and making method.Have that pipeline turns round easily, homogeneous heating, the little feature of thermal losses.
In order to achieve the above object, technological scheme of the present invention is: a kind of energy-saving melt pipe, comprise the chrome molybdenum pipeline of inner wall smooth, and described chrome molybdenum pipeline external surface is provided with heating equipment, and described heating equipment outer surface is provided with thermal insulation layer.
Described chrome molybdenum pipeline external surface is evenly wound with heating equipment, and described heating equipment is stainless steel heating wire.
A kind of manufacture method of energy-saving melt pipe: adopt chrome molybdenum pipeline material, first polishing is carried out in its surface, again the chrome molybdenum pipeline material after polishing is carried out to hard chromium plating, then the chrome molybdenum pipeline material after hard chromium plating is manufactured to the chrome molybdenum pipeline that pressure resistance reaches 50MPa, then at chrome molybdenum pipeline external surface, be wound around stainless steel heating wire, finally at the coated thermal insulation layer of the chrome molybdenum pipeline external surface that is wound with stainless steel heating wire.
The invention has the beneficial effects as follows: the present invention is by comprising the chrome molybdenum pipeline of inner wall smooth, and described chrome molybdenum pipeline external surface is provided with heating equipment, and described heating equipment outer surface is provided with thermal insulation layer.Described chrome molybdenum pipeline external surface is evenly wound with heating equipment, and described heating equipment is stainless steel heating wire.Its manufacture method: adopt chrome molybdenum pipeline material, first polishing is carried out in its surface, again the chrome molybdenum pipeline material after polishing is carried out to hard chromium plating, then the chrome molybdenum pipeline material after hard chromium plating is manufactured to the chrome molybdenum pipeline that pressure resistance reaches 50MPa, then at chrome molybdenum pipeline external surface, be wound around stainless steel heating wire, finally at the coated thermal insulation layer of the chrome molybdenum pipeline external surface that is wound with stainless steel heating wire.Make that pipeline turns round easily, homogeneous heating, the little feature of thermal losses.
 
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Embodiment 1
An energy-saving melt pipe as shown in Figure 1, comprises the chrome molybdenum pipeline 1 of inner wall smooth, can be crooked arbitrarily as required.Described chrome molybdenum pipeline 1 outer surface is provided with heating equipment, and described heating equipment outer surface is provided with thermal insulation layer 3.
Described chrome molybdenum pipeline 1 outer surface is evenly wound with heating equipment, and described heating equipment is stainless steel heating wire 2.
A kind of manufacture method of energy-saving melt pipe, adopt chrome molybdenum pipeline material, first polishing is carried out in its surface, again the chrome molybdenum pipeline material after polishing is carried out to hard chromium plating, then the chrome molybdenum pipeline material after hard chromium plating is manufactured to the chrome molybdenum pipeline that pressure resistance reaches 50MPa, then at chrome molybdenum pipeline external surface, be wound around stainless steel heating wire, finally at the coated thermal insulation layer of the chrome molybdenum pipeline external surface that is wound with stainless steel heating wire.
Adopt chrome molybdenum material to form through polishing, hard chromium plating, processing and fabricating, the withstand voltage 50MPa of reaching when assurance pipeline is normally used, inner-walls of duct is smooth without delay, the oxidation of can not getting rusty; Can be crooked arbitrarily as required; Surface is wound around stainless steel heating wire, guarantees all even rapid of heating-up temperature; Outer surface is coated thermal insulation layer, guarantees that outside belongs to normal temperature, there will not be and scald unintentionally phenomenon, and melt heat does not leak, and the energy does not have loss, thereby has saved the energy.Using effect is significantly better than conventional pipeline.
