Abstract
The invention discloses a water heater liner, which belongs to the technical field of the water heater. The water heat liner is characterized in that the manufacture process is blow molding process; the water heater liner is made of engineering plastic; the whole water heater liner has a barrel shape; more than three flanges are designed on the lateral wall of the barrel; flanges are arranged at two ends of the lateral wall of the barrel; two end faces of the barrel are convex surfaces projecting outward; the embodiment I of the engineering plastic is modified polyphenyl ether, and the embodiment II of the engineering plastic is reinforced modified polypropylene; the embodiment I of the barrel is a vertical type with central axis in vertical direction, and a hole is formed in the center of the lower end face of the barrel; and the embodiment II of the barrel is a transverse type with the central axis in horizontal direction, and a hole is formed in the center of the lower side of the barrel. The water heater liner has the advantages of simple process, small equipment investment, lower production cost, good corrosion resistance, good temperature preservation, excellent electric performance and long service life.
Description
Technical field
The present invention relates to a kind of water heater liner of hollow blow molding, belong to technical field of water heaters.
Background technology
The water heater of prior art has two big classifications: the one, and electric heater, the 2nd, solar water heater.The principle that this two classes water heater adds hot water is different, but the major function of the inner bag of two class water heaters all is a water storage, and it must possess insulation, withstand voltage, non-corrosive, no incrustation scale, impermeable characteristic.The preparation method of the inner bag of this two classes water heater also is similar thus.
Material a multitude of names of water heater liner in the market, but in fact the inner bag of water heater mainly contains two kinds of stainless steel inner container and enamel inner containers.So-called titanium inner bag, golden Gui inner bag, quartzy enamel, sapphire or the like, but be to plate silicide or rare metal alloy (improving corrosion resistance and intensity to a certain extent) these two kinds main material outsides, individual call changed.
The advantage of stainless steel inner container is that the inner bag material is good, intensity is high, high temperature resistant, stable performance is difficult for getting rusty.But it has two big shortcomings: the one, be difficult to welding, and in technological process, easily produce the rosin joint phenomenon, and be difficult for being found, leak with regard to easily getting rusty between long slightly weld seam of time, and rosin joint can't be checked before partly dispatching from the factory; The 2nd, be difficult to solve etching problem, especially commissure.
The enamel on enamel inner container surface is nonmetallic materials, and its advantage is both non-corrosive, does not also have incrustation scale, and stronger voltage endurance capability is arranged.But common enamel inner container has 3 weak points: the first, and fishscale is the critical defect of common enamel inner container; The second, enamel belongs to silicate, the slow dissolving of meeting, attenuation, i.e. boiling water weightlessness in high-temperature water; The 3rd, acid water confrontation enamel inner container has great destructiveness.
Stainless steel inner container and enamel inner container also have two common shortcomings: the one, and the processing technology complexity, equipment investment is bigger; The 2nd, production cost is higher.
Inner bags such as titanium inner bag, golden Gui inner bag, quartzy enamel, sapphire, be to plate silicide or rare metal alloy at stainless steel inner container or enamel inner container master material outside, can improve corrosion resistance and intensity to a certain extent, but it makes further process complications, equipment investment increase, production cost improve.
The invention provides a kind of water heater liner that solves above-mentioned all kinds of water heater liner shortcomings.
Summary of the invention
The object of the invention is to provide that a kind of processing technology is simple, equipment investment is little, production cost is lower, anticorrosive property is good, the water heater liner of good heat preservation performance, long service life.
For achieving the above object, the present invention adopts following technical proposals:
Water heater liner manufacture craft of the present invention is a hollow blow molding technology: plant equipment is the System of Hollow Blow Shaping Machine tool, selects suitable engineering plastics that can blow molding, designs suitable mould and carries out hollow blow molding, one-shot forming.
Water heater liner material of the present invention adopts engineering plastics, and this project plastics must have excellent comprehensive performances: acid and alkali-resistance, electrical property is good, water imbibition is little, heat resistance high (can use for a long time more than 100 ℃), have that higher intensity, this material are nontoxic to human body, this material is applicable to hollow blow molding technology.The selection of material is given an example: Noryl, enhancing modified polypropene.
The overall shape of water heater liner of the present invention is a cylinder body, can be vertical (axis is at vertical direction), also can be (axis in the horizontal direction) of horizontal type; For improving the intensity of water heater liner, design three above chimbs 2 on the sidewall 1 of water heater liner cylinder body, there is chimb 3 at the two ends of cylinder body sidewall, and the both ends of the surface of cylinder body are convex surface 4 and the convex surfaces 5 that outwards protrudes; Vertical water heater liner is opened a hole 6 at the center of its lower surface 5, can be installed into devices such as water pipe, outlet pipe, electric heating tube, temperature sensor on the cover plate in this hole, add a sealing ring between cover plate and the hole, cover plate and water heater liner are fastening firmly with securing member; Open in the center of its downside 1 in the hole 6 of the water heater liner of horizontal type, and the effect and the fastening method of the cover plate in this hole are same as described above.
The present invention has following conspicuous advantage compared with prior art:
1, technology is simple, equipment investment is little.
2, production cost is lower.
3, anticorrosive property is good.
4, good heat preservation performance.
5, good, the good insulating of electrical property.
6, long service life.
