Abstract

A kind of dining room electrically heated boiler, furnace body shell including cuboid and the liner holder by a plurality of they sup-port center in furnace body shell, furnace body outer casing bottom is supported by supporting leg, there is the identical liner of shape positioned at upper and lower they sup-port further through a plurality of inside liner holder, and it is closed between liner and liner holder and vacuumize to form vacuum area, liner lateral wall coils the heating tube for having uniform fold, liner inside top is provided with the water inlet pipe being in communication with the outside and is communicated with the temperature and water-level gauge for reaching bottom, liner interior bottom portion is then communicated with depotition cock, liner holder is cylinder, and one layer of silver layer is coated in vertical cambered surface.The utility model can effectively transfer heat to liner, and effectively heat radiation concentration can be reflected into liner, the heat of generation is preferably acted on the water inside liner, improves heating efficiency and heat utilization ratio.

Description

A kind of dining room electrically heated boiler

Technical field

The utility model relates to a kind of boiler, specifically a kind of dining room electrically heated boiler.

Background technique

Dining room is that flow of personnel amount and hot water demand measure biggish place, and almost all of dining room is equipped with for supplying The boiler of hot water, most of boilers are electric furnace, but the design of current electric furnace structure is not reasonable, cannot effectively by The gathering in water to be heated of more concentrating of heat that electrothermal tube generates, lead to the thermal efficiency of filtering and produce the efficiency of hot water compared with It is low.

Utility model content

To solve the above problems, the purpose of the utility model is to provide a kind of dining room electrically heated boilers.

The utility model to achieve the above object, a kind of dining room electrically heated boiler, the furnace body shell including cuboid With the liner holder by a plurality of they sup-port center in furnace body shell, furnace body shell is made of stainless steel, furnace body shell Bottom is supported by supporting leg, is located at upper and lower they sup-port further through a plurality of inside liner holder and has the identical liner of shape, interior Gallbladder shell and liner are made of stainless steel, and thickness is thicker, can fully ensure that intensity, and edge uses sealing welding It connects, and closed between liner and liner holder and vacuumize to form vacuum area, liner lateral wall coils the heating for having uniform fold Pipe, liner inside top are provided with the water inlet pipe being in communication with the outside and are communicated with the temperature and water-level gauge for reaching bottom, liner Interior bottom portion is then communicated with depotition cock, and liner holder is cylinder, and one layer of silver layer is coated in vertical cambered surface.

The heating tube of the utility model is located in vacuum area, and heating tube be tightly wound around liner periphery, can effectively by Heat transfer is to liner, and vacuum structure has good insulation ability, and heat is effectively prevent to dissipate by liner holder It is dealt into the external world；The periphery of heating tube be provided with a circle for reflection silver coating, can effectively by heat radiation concentrate reflection Into liner, plays the role of heat build-up and concentrate heat, the heat of generation is preferably acted on into the water inside liner, improve and add The thermal efficiency and heat utilization ratio, and the speed aoxidized after the heating of electroplate layer can also be effectively reduced in the vacuum formed, it is ensured that The reflex of silver coating is permanently effective.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

As shown in Figure 1, a kind of dining room electrically heated boiler, furnace body shell 1 including cuboid and pass through a plurality of support Bar 2 is supported on the liner holder 3 at center in furnace body shell 1, and 1 bottom of furnace body shell is supported by supporting leg, and 3 inside of liner holder is again logical Cross it is a plurality of be located at upper and lower support rod 2 and be supported by the identical liner 4 of shape, and it is closed between liner 4 and liner holder 3 and take out true Sky forms vacuum area 5, and 4 lateral wall of liner coils the heating tube 6 for having uniform fold, and 4 inside top of liner is provided with the external world even Logical water inlet pipe 7 and it being communicated with the temperature for reaching bottom and water-level gauge 8,4 interior bottom portion of liner is then communicated with depotition cock 9, Liner holder 3 is cylinder, and one layer of silver layer 10 is coated in vertical cambered surface, the 5 upper end lower end of vacuum area in liner holder 3 Also be welded with zinc bar 12, zinc bar 12 can be preferentially in conjunction with oxygen remaining in vacuum area 5, it is ensured that silver layer 10 high-temperature heating not by Oxidation, to guarantee the reflective of long duration.

Thermal insulation material 11 is filled between furnace body shell 1 and liner holder 3, thermal insulation material 11 is glass silk floss.

Liner holder 3 and 4 section of liner are inverted isosceles trapezoid, and heating tube 6 extends to liner at the bottom, in this way on toward Under become narrow gradually, heat internal water when, heat can rise from lower to upper, and heat is more concentrated compared with traditional cylindrical tube Into the water on upper layer, be conducive to improve whole heating efficiency.

5 vacuum degree of vacuum area is -7 to -8Pa, certainly can also be according to the intensity of liner holder 3 and liner 4 come appropriate Increase vacuum degree, or reduces vacuum degree.

The standardized element that the utility model uses can commercially, shaped piece according to specification and attached drawing Record can carry out customized, the specific connection type of each part is all made of in the prior art mature bolt, rivet, weldering Equal conventional means are connect, this will not be detailed here.

Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above, this The those of ordinary skill of technical field, in the essential scope of the utility model, variation, change, addition or the replacement made, all It should belong to the protection scope of the utility model.
