Abstract

The utility model relates to a steam generating device, in particular to a non-boiler intermittent steam generating device, characterized in that a coil pipe is covered outside the heating pipe, an annular passage is left between the coil pipe and the heating pipe, two ports of the coil pipe are sealed with the heating pipe, the wire of the heating pipe is deviated from two sides, a water inlet and a steam outlet are provided on the coil pipe, and the integral is placed in heat-insulating cotton. The purpose is to design a steam generating device which is convenient to control and safe. Compared with existent techniques, the utility model has the advantages of simple structure, quick steam generation, either continuous or intermittent use of steam, and wide application area.

Description

Steam generating device

Technical field

The utility model relates to steam generating device, particularly relates to the intermittent steam generating device of a kind of no boiler.

Background technology

The steam generating device kind is a lot of in the market, its architectural feature roughly can reduce two classes: the first kind is a boiler formula structure, in an airtight container, add a certain amount of water, make the water boiling produce steam, by cap relief valve and pipeline steam is sent to again and uses the position by heating.The problem that exists is: 1, used pressure vessel, certain danger is arranged; 2, steam recurs and intermittent the use is a contradiction, solve it safety device need be installed, and discharges unnecessary steam and come release when steam pressure is too high, and the steam that emits will influence the safety of working environment; 3, the steam end is wanted mounted valve, and the control steam send and stops, and valve is under the condition of high temperature, and valve will be used special material and special construction.4, boiler level control and automatic watering apparatus are also very complicated.Second class is the atomizing structure, with a sprayer unit water that atomizes is sprayed at heater surfaces, and moment produces steam, with air blast vapor pump is arrived and uses the position.This device does not have boiler, does not have HCS, and is dangerous less.But this device air blast service condition is more abominable, and the life-span is short; The steam generation chamber needs bigger space, and is very not compact on the structure, and steam is by the powerful conveying of air blast, and the steam flow velocity is than difficult control.

Summary of the invention

The purpose of this utility model is the steam generating device that design is a kind ofly controlled conveniently, security is good.

In order to achieve the above object, the utility model adopts following technical solution: a kind of steam generating device, comprise heating tube, it is characterized in that at heating tube overcoat sabot pipe, leave the circular passage between coil pipe and the heating tube, coil pipe two-port and heating tube sealing, the heating tube wiring is drawn from two ends, also be provided with water inlet and vapor outlet port on coil pipe, integral body places heat-preservation cotton.Water inlet connection traffic adjuster and magnetic valve.

Owing to utilize the interlayer between bilayer sleeve to add hot water, produce steam, structure is very simple, the problem that does not also have steam to reveal, security is fabulous, and installing space is seldom; Simultaneously, this device vapor outlet port place does not need valve control, avoid using specific components, by regulating the flow or the break-make of flow regulator and solenoid valve control water, just can control the generation and the conveying of steam well, the steam end does not have gate, does not definitely have the too high problem of steam pressure to take place.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is present embodiment principal section figure.

Fig. 2 is Fig. 1 left profile figure.

The specific embodiment

As Fig. 1-shown in Figure 2, present embodiment comprises coil pipe (1), heating tube (3), heat-preservation cotton (5), protective cover (6), flow regulator (7), magnetic valve (8) and thermocouple (9).Heating tube (3) is sleeved in the coil pipe (1), leave circular passage (10) between coil pipe and the heating tube, coil pipe two-port and heating tube welded seal (11), heating tube wiring (12) is drawn from two ends, also be provided with water inlet (2) and vapor outlet port (4) in the coil pipe both sides, water inlet (2) connection traffic adjuster (7) and magnetic valve (8), thermocouple (9) is located on the coil pipe (1).Coil pipe (1) is circular with coiling together after heating tube (3) welding, or shapes such as dish squarely, snakelike, polygon, and integral body places heat-preservation cotton (5), and heat-preservation cotton (5) is peripheral to be encased by protective cover (6).

In water enters circular passage between coil pipe (1) and the heating tube from the left end water inlet, water is heated the pipe Fast Heating when flowing through the circular passage, produce steam, and steam is overflowed from the right-hand member vapor outlet port, regulate the flow of water inlet saliva, can guarantee to be vaporized into steam fully to the water of the port of export.When using steam continuously, magnetic valve often leaves, and regulates inflow, overflows up to steam end no liquid, can use steam continuously; Intermittently use steam and intermittent time more in short-term, electrothermal tube is controlled by thermocouple, remains uniform temperature, and the water inlet magnetic valve opens or closes, and that just can control steam has or do not have; Intermittent time, the tempus intercalare electric heating tube was in not heated condition when longer, when needing steam, and electric heater for heating, magnetic valve is delayed about unlatchings in 10 seconds (length of time-delay or weak point can be set) can use steam; When stopping, magnetic valve cuts out in advance, and heating tube is delayed outage in about 10 seconds, can avoid the inner ponding in circular passage, and the object that need be heated up by electric heating tube in this device is exactly a heating tube itself, so programming rate is very fast, can satisfy actual needs.

In sum, the utility model compared with prior art has the following advantages:

1, structure is very simple.

2, steam generation speed is fast.

3, steam can use continuously and can intermittently use.

4, this device can be widely used in many-sides such as clothes ironing equipment, bating equipment, steam sterilization sterilizing equipment decontaminating apparatus.
