Abstract
The utility model discloses an air heater which comprises a case and a heater arranged in the case, the heater is formed by high-frequency ceramic and heating coils, the section of the high-frequency ceramic is provided with 6 through holes, and the inner walls of the through holes are provided with bulges which are in triangular arrangement and are used for supporting the heating coils. The heating coils are supported on the inner walls of the through holes in a bulge point form, so that the contact surface of cool air and the heating coils is increased, the air is guaranteed to flow from the three sides of the heating coils, and thus the heating efficiency is improved.
Description
Technical field
The utility model belongs to firing equipment, relates in particular to a kind of industrial hot blast generation machine.
Background technology
Industrial air-heater is widely used in the industries such as electronics, food, pharmacy, printing, packing, and its critical piece is air blast, heating element.Heating element consists of the heating wire that honeycombed cylinder and the brace rod support of chamber wall within it arrange, the heating element of this structure, because the arrangement form of the through hole of honeycombed cylinder is unreasonable, thereby cause the contact area of cold air and heating wire little, the efficiency of heating surface is on the low side.
The utility model content
The utility model, for the problem that prior art exists, provides a kind of efficiency of heating surface high air-heater.
For practical above purpose, the utility model is achieved in that a kind of air-heater, comprises cabinet
And the heater that is formed by high-frequency ceramic and heating wire that arranges in cabinet, the cross section of described high-frequency ceramic offers the through hole of 3 multiple, and the inwall of described through hole is furnished with the projection that is used for supporting heating wire of triangular layout.
The quantity of described through hole is 6,12,18 or 36.
Compared with prior art, designed the through hole of 3 times of quantity due to the inner chamber of high-frequency ceramic, and on through-hole wall, the point format with projection supports heating wire, has increased the contact area of cold air and heating wire, guarantee three side flow of air from heating wire, thereby improved the efficiency of heating surface.
Description of drawings
Fig. 1 is the structural representation of air-heater.
Fig. 2 is the installation diagram of heater.
Fig. 3 is the cross section structure figure of heater.
Fig. 4 is the partial enlarged drawing of Fig. 3.
The utility model is described in further details with most preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, air-heater is comprised of base 1, air blast 7, cabinet 6, heating element 8, thermocouple 3, electrical control cubicles 2.Air blast 7, cabinet 6 and electrical control cubicles 2 are installed on base 1, and cabinet 6 tops arrange cylinder 4, and cabinet 6 side openings are provided with shutter.Pipe 4 outer wrapping thickness are high-purity type refractory fiber blanket 5(low heat conductivity of 25mm, 1260 ℃ of high refractory temperatures), high insulating effect, heat loss are low.The air outlet place of cylinder 43 hangs thermocouple.
As shown in Figure 2, cylinder 4 inside arrange heating element 8, and heating element 8 consists of high-frequency ceramic 9 and heating wire 10.
As shown in Figure 3, it is certain that high-frequency ceramic is that Qi Transverse cross section of post shapes ， offers the through hole 11(of 6 perforations, and the quantity of through hole also can be designed to 12,18 or 36 according to practical situations), the inner wall even distribution of through hole 11 arranges 12,3 projections of 3 projections, and to be equilateral triangle uniform.Heating wire turns to spiral-shaped by specific purpose tool, it is arranged in the through hole of high-frequency ceramic, and by projection, is supported.High-frequency ceramic has that dielectric constant is little, and dielectric loss is low, and mechanical strength is high, and the performances such as higher dielectric strength, insulaion resistance and thermal conductivity.Heating wire adopts high pure 2080 nickel filaments of intensity under nonmagnetic, corrosion-resistant and high temperature to do heater element, does not contain irony, is difficult for oxidation, and long service life, serviceability temperature can reach 800 degrees centigrade.Because heating wire directly contacts with air, can fast the generation heat be converted to the hot-air of higher temperature, air evenly passes through from the both sides of spirality heating wire, the thermal efficiency high (near 100% thermal conversion rate).
As shown in Figure 4, the supporting surface of each projection 12 of through hole 11 inwalls is the indent arc-shaped surface.
Claims (2)
1. air-heater, comprise arrange in cabinet and cabinet by adding that high-frequency ceramic and heating wire form
Hot device is characterized in that: the cross section of described high-frequency ceramic offers the through hole of 3 multiple, and the inwall of described through hole is furnished with the projection that is used for supporting heating wire of triangular layout.
2. air-heater according to claim 1, is characterized in that, the quantity of described through hole is 6,12,18 or 36.
