Abstract

The utility model relates to a portable numerical control coal-electricity double-purpose normal pressure boiler, which comprises a boiler body, an upper water tank, a lower water tank, a base, an electric heating system, an automatic numerical control box and a numerical thermometer. The portable numerical control coal-electricity double-purpose normal pressure boiler is characterized in that a hearth is formed by a coal stove and the electric heating system; a steam outlet pipe is arranged on the sidewall of the hearth; two ends of a water pipe are respectively connected with the upper water tank and the lower water tank; a hot water tank is provided with an observation hole, a cupola pipe and a cylindrical body; an electric heating pipe is arranged in a sandwich layer between the hearth and a boiler body; and the automatic numerical control box and the numerical thermometer are arranged outside the hearth. The measures are implemented, the boiler not only can use coal, but also use electricity; and the water tanks are added above the boiler, thereby not only reducing the external temperature of the boiler, but also reducing the occupied area of the system. The thermal efficiency of the boiler is obviously improved compared with the prior similar boiler.

Description

A kind of portable numerical control coal, electric ordinary-pressure boiler for both

Technical field:

The utility model relates to boiler, particularly a kind of portable numerical control coal, electric ordinary-pressure boiler for both.

Background technology:

Being of wide application of boiler, but traditional vertical water tube boiler insulation construction inwall directly contacts with high-temperature flue gas, thereby cause insulation material requirement height, thickness is big, radiation loss is big, surface temperature is too high, also need join softened water tank in addition, what have also need be provided with the waste-heated water-tank to improve the efficient of boiler at the flue gas afterbody.Cause that system layout is huge, complicated, floor space is big.

Summary of the invention:

The utility model purpose is in order to solve the deficiency that the above-mentioned background technology exists, to provide a kind of simple in structure, make boiler easy to maintenance, easy use, a kind of coal, electric dual-purpose especially is provided, can being decided to be the normal-pressure boiler of fully automatic working during electricity consumption.

For achieving the above object, the utility model adopts following technical scheme:

A kind of portable numerical control coal, electric ordinary-pressure boiler for both comprise boiler body, upper water box, and lower header, base constitute, and it is characterized in that, and described boiler body is by upper water box, electric heating tube, burner hearth, the automatic numerical control case, the digital temperature instrument is formed; Electric heating tube is located at the interlayer of burner hearth and body of heater, and the digital temperature instrument is placed in the burner hearth outside, and described burner hearth is made of coal stove and electric heating system, and burner hearth sidewall is provided with steam outlet pipe, and the two ends of water pipe link to each other with lower header with upper water box respectively; The described boiler of going up is made of peep hole and cover plate, impact tube and cylindrical shell.

Boiler is a steel vessel, which is provided with the liquid level gauge metered valve, it has down water level meter valve device, boiler one side is equipped with out the vapour bend pipe, the upper end and the lower hot water tank that go out the vapour bend pipe are connected, and steam-water separator is equipped with in the lower end, with vapour, water separately, by the outside steam supply of venthole, outwards supply water by discharge outlet.

The utility model makes boiler both can use coal owing to implemented its technique effect of above-mentioned measure and be, also can electricity consumption, above boiler, increase upper water box, and both reduced boiler appearance temperature, reduced system's floor space again.Boiler thermal output is significantly improved than existing similar boiler.

The utility model is mixed numerical control control, can realize fully automatic operation, has safe and reliable, the unique novelty of structure, makes characteristics such as easy, compares with similar existing product, heat loss is little, thermal efficiency height, and cost is low, floor space is little, because water capacity is little, and the operation safety and reliability.This product can be made into series of products in 0.1t/h.Being mainly used in clothing industry and small-sized enterprise and institution and family uses.
