Abstract

The utility model relates to an automatic steam water boiling device in which the steam is served as the heat source, composed of a double-layer-metal sealing container 1, a steam tube 2 with a fin 9, a water inlet pipe 3, a water outlet 4, an electromagnetic valve 5 for controlling automatically water supply, a water level sensor 6, a steam electromagnetic valve 7 for controlling automatically heating, and a temperature controller 8. The utility model having economical use, safety, high heat efficiency is especially suitable for the company which has the boiler and wants to substitute the electric boiling-water heater.

Description

Automatic steam water boiling device

The utility model belongs to heater, particularly steam-heated boiler.

With the immediate technology of the utility model be automatic electric water-boiling device, therefore it can control water inlet automatically, heats automatically, can provide boiling water continuously, uses very convenient and safety, is widely used in enterprises and institutions and public places such as factory, school, hotel.But because the present electric power resource anxiety of China, electricity price is higher, uses the electrical heating boiling water very uneconomical.Particularly be provided with the unit of steam boiler, if heat then comparatively economical with steam.Before the utility model, also existing steam boiler, but its water inlet and all necessary Artificial Control of heating, otherwise can not guarantee boiling water without interruption, and this boiler is then unhygienic in the place of factory, station or other environmental pollutions owing to will not sealed usually by manually-operated, the steam boiler that has, even steam directly led to the water that is heated, then boiler water and drinking water mix just more unhygienic; Simultaneously, the steam heat-exchange tube that this boiler adopts mostly is straight tube, rate of heat exchange heterodyne, and Artificial Control such as untimely and accurate, and the waste and dangerous the treating of then causing the energy have influenced the extensive use of steam boiler.

The purpose of this utility model just provides a kind of automatic steam boiler, adopts Steam Heating, and can control water inlet automatically, heats automatically, and the raising heat exchanger effectiveness, boiler sealing and insulation are with energy savings, health boiling water without interruption, safe in utilization and convenient.

The purpose of this utility model is achieved in that

Automatic steam boiler of the present utility model, chew by container, steam pipe, water inlet pipe and water outlet and to be basic comprising, container is preferably the double-level-metal container, adopt the metal material processing that is shaped easily, and the double-level-metal structure is beneficial to insulation and avoid skin temperature high and cause scald etc., can fill insulant material between the double-level-metal, also can be by the air thermal insulation, and container is an airtight container with cover; Generally all be located at the container bottom according to the heating principle steam pipe, and, all adopt helical structure in order to increase heat exchange area; According to conventional design, water inlet pipe is positioned at the top of container, and water outlet is chewed and then is positioned at the container bottom; Of the present utility model being characterised in that: a. advance no matter on be provided with magnetic valve, this magnetic valve is by the level sensor control of being located in the container, constitute automatic water inflow device, promptly when water level reaches nominal position, level sensor control electromagnetism is closed, stop into water, when water level drops to a certain position, water inlet is opened, replenished to level sensor control magnetic valve, magnetic valve and level sensor all are prior art and setting product, its method of attachment and the setting of water level up and down, those skilled in the art all can implement; B. the admission end at steam pipe is provided with steam electromagnetic valve, the temperature controller that this steam electromagnetic valve is located in the container by probe is controlled, constitute automatic heating apparatus, promptly when water temperature reached boiling point, temperature controller control steam electromagnetic valve was closed, stop heating, when water temperature was lower than a certain design temperature, temperature controller control steam electromagnetic valve was opened, and reheats, equally, the enforcement of steam electromagnetic valve and temperature controller is also grasped by those skilled in the art; C. the spiral steam pipe that carries out heat exchange in container is finned heat-exchange tube, to improve the efficient of heat exchange.

Technique scheme of the present utility model, realized above-mentioned the purpose of this utility model fully, water inlet of steam boiler and the automatic control of heating have promptly been realized, and safe and sanitary, the particularly improvement of heat-exchange tube makes the consumption of steam save 30～40%, saves heat time heating time about 30%, for the unit that is provided with boiler provides a kind of economic boiler that uses, can replace electric water-boiling device fully.

Embodiment of the present utility model and description of drawings are as follows:

Fig. 1. be automatic steam boiler side semi-section schematic diagram;

Fig. 2. be the positive partial cutaway schematic of automatic steam boiler;

Fig. 3. be the circuit diagram of automatic steam boiler.

Among the figure, the 1st, the double-layer stainless steel container is the air thermal insulation between the double-deck stainless steel, and seal cover is arranged above the container; The 2nd, steam pipe, the 3rd, water inlet pipe, figure middle steam tube 2 and water inlet pipe 3 all enter container 1 perpendicular to the back side of container 1, and this only is in order to express conveniently, generally can be provided with elbow and to make pipeline be close to the back side of container 1, installing so that boiler can be close to wall; The 4th, water outlet is chewed, and water outlet chews 4 can one to two, decide on container 1 volume, and the 5th, magnetic valve, the 6th, the gasbag-type level sensor, the 7th, steam electromagnetic valve, the 8th, compression-type temperature controller is set at the bottom of container 1, and the 9th, the fin on the heat exchange steam pipe.

In order to continue the use boiler at power failure or automatic water inflow device with when heating apparatus breaks down automatically, on the steam electromagnetic valve 7 of the magnetic valve 5 of water inlet pipe and steam pipe admission end, be parallel with manually-operated gate 10 and steam manually-operated gate 11 respectively.

Fin 9 on the heat exchange steam pipe 2, the simplest generation way and structure be with little metal book slip around and be embedded on the steam pipe 2.

Present embodiment also is equipped with pole pair 12 as water mangetizer on water inlet pipe, the water that enters boiler is magnetized, and magnetized drinking water not only is of value to human body, and can stop water to form incrustation scale in the boiler container.

On the front plate of boiler, the glass tube water level display 13 that communicates with container 1 inside is housed, water-thermometer 14, power supply indicator 15 and burner on light 16.

For preventing the obstruction of heat exchange steam pipe 2, be provided with vapor filter 17 at the admission end of steam pipe 2, the end of steam pipe is provided with drain valve 18 routinely.

For fear of because level sensor 6 is malfunctioning or go up water levels and transfer too highly, the water that container is 1 li overflows, be provided with the overflow pipe 19 that communicates with container 1 top, and overflow pipe 19 is located in the interlayer of double container, make the container profile complete attractive in appearance, container 1 bottommost also is provided with drainpipe 20 and water discharging valve 21, so that can be with the water emptying of container during cleaning container.
