Description

Fast steam boiler

Technical field

The utility model is related to steam boiler more particularly to a kind of boilers of Rapid steam output.

Background technology

Existing steam boiler, including pressure vessel, heater, pressure vessel are equipped with water inlet, sewage draining exit, go out steam Mouth, pressure gauge, safety valve etc. store a large amount of flowing to be heated between internal pressure vessel walls and the heating surface of heater Water or steam, and the volume of such water or steam to be heated is prodigious, under conditions of heater power is certain, Want these water to be heated or steam being heated to required vapor (steam) temperature, generally requires to wait for for a long time, be not achieved quickly Go out the purpose of steam.

Utility model content

To overcome the originally heating cold water of existing steam boiler, to steam stand-by period too long of defect is gone out, this practicality is new Type the technical solution adopted is that：

The water that flowing is added in heater heated pressure container forms steam, in heater wattage output and heated pressure In the case that heating area when container inner medium is certain, the method for reducing heated medium volume in pressure vessel can be used, Quickly the medium in pressure vessel is made to heat up to realize, to achieve the purpose that Rapid steam output；And fully to reduce pressure vessel The interior volume for being added hot medium, on the one hand can be by the small as possible of design of pressure vessels, as long as heater is generated heat bread Contain into just；On the other hand identical or not of uniform size sky can be filled between pressure vessel and heater heating surface Heart steel ball or hollow rod iron make to be heated by the heaters to supplant the volume of a part of cold water or steam in pressure vessel Cold water or steam medium amount are reduced；Due to using determining heating power, heating the seldom cold water or steam stayed, quickly It will obtain the steam of required temperature or pressure.

The hollow rod iron, the closed both ends for being welded on steel pipe of end cap outwardly protruded for both ends ball.

The hollow rod iron is at least between an electrothermal tube for being placed in the heater and the internal pressure vessel walls, and with The electrothermal tube of heater is parallel, and is also attached on deflector with the electrothermal tube of heater, and the deflector is equipped with uniform The aperture of distribution is passed perpendicularly through in aperture by the electrothermal tube of the heater is alternate with the hollow rod iron, is welded and fixed, with row Squeeze out the volume of a part of cold water or steam in the pressure vessel.

The hollow steel ball is closed hollow global shell.

The hollow steel ball or hollow rod iron, wall thickness can bear the maximum internal pressure of the pressure vessel, be unlikely to shrivel Or damage hollow steel ball or hollow rod iron by pressure.

The hollow steel ball or hollow rod iron, internal pressure are negative pressure.

The hollow steel ball or hollow rod iron, internal pressure are positive pressure.

The hollow steel ball or hollow rod iron, it is internal or be equipped with substance of the thermal coefficient less than the thermal coefficient of water, by In the small substance of filling thermal coefficient inside it, the pressure difference of the front and back interior ectosphere wall of hollow steel ball heating can be alleviated, so It is safer.

At least provided with one layer of permeable elastomeric flexible blanket pad between the internal pressure vessel walls and the heater heating surface, use The stress that the hollow steel ball or hollow rod iron in the alleviation medium expand with heat and contract with cold.

The fence is set to water inlet, goes out at steam port and sewage draining exit, is made of metal grill, is fixed on the pressure and holds On device inner wall, for blocking hollow steel ball or hollow rod iron, prevent hollow steel ball or hollow rod iron from being leaked from the pressure vessel Go out；Another effect is to ensure that hollow steel ball or hollow rod iron are unlikely to block water inlet, go out steam port, sewage draining exit and safety valve Mouthful.

Specific implementation mode

It is the horizontal electric heating steam boiler of three-phase alternating current in Fig. 1~Fig. 3, hollow rod iron 25 is that the both ends of steel pipe 28 are used 29 welded closure of spherical surface end cap outwardly protruded, the electrothermal tube 27 that heater 2 is at least placed in by a hollow rod iron generate heat Between face 10 and internal pressure vessel walls 9, and it is parallel with the electrothermal tube of heater 2 27 and same as the electrothermal tube of heater 2 27 It is fixed on fixed deflector 26, fixed deflector 26 is equipped with equally distributed aperture 34, by heater 2 in aperture 34 Electrothermal tube 27 is alternate with hollow rod iron 25, passes perpendicularly through, and welds, fixes, to supplant a part of cold water 11 in pressure vessel 1 Or the volume of steam 12, so that the cold water 11 heated by the electrothermal tube 27 of heater or 12 medium of steam is reduced, due to utilizing determination Heating power, heat the seldom cold water 11 or steam 12 stayed, and water 11 can also be met and surround heater heating surface 10, So the steam 12 of required temperature or pressure will soon be obtained, to reach the mesh that the utility model quickly goes out steam 's.

It is 25 schematic diagram of hollow rod iron in Fig. 1 in Fig. 3.Both ends are welded on stainless for the end cap 29 that spherical surface outwardly protrudes 28 both ends of steel pipe.

Wherein fence 17 is set to water inlet 3, goes out steam port 5 and sewage draining exit 4,7 mouthfuls of safety valve, is made of metal grill, Gu It is scheduled on internal pressure vessel walls 9, is prevented from pressure vessel 1 to leakage for blocking hollow steel ball 13,16 and hollow rod iron 25 Go out；Another effect is to ensure that 13,16 or hollow rod iron 25 of hollow steel ball is unlikely to block water inlet 3, goes out steam port 5, blowdown 7 mouthfuls of mouth 4 and safety valve.

It is vertical fuel open firing steam boiler in Fig. 4, tightening patch in internal pressure vessel walls 9 sets one layer of water penetration Soft blanket pad 15, permeable elastomeric flexible blanket pad 15 is irregularly pressed together with stainless steel metal wire is made sheet, has The blanket pad of elasticity；Be filled between vertically-arranged internal pressure vessel walls 9 and heater heating surface 10 the unlimited hollow steel ball 13 of size, 16, including vacuum hollow steel ball, or the hollow steel ball 16 of built-in hollow or small thermal coefficient substance is filled, to supplant big portion Divide the volume of cold water 11 or steam 12, it is same as above to achieve the purpose that the utility model Rapid steam output.

It is 13 sectional view of hollow steel ball in Fig. 5；It is equipped with air or the small substance of thermal coefficient in 13 intracavitary of hollow steel ball 14, the hollow steel ball 16 of the small substance of built-in thermal coefficient is just constituted, this hollow steel ball can reduce interior before and after it is heated The pressure difference of ectosphere wall.

In Fig. 6, sheet is made irregularly to be pressed together with stainless steel metal wire 33, flexible permeable bullet Property soft blanket pad 15, the stress to expand with heat and contract with cold for relieving stress the hollow steel ball 13,16 in 1 medium of container is bad to prevent supportting Pressure vessel 1 or heater heating surface 10.

Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to In this, to pressure vessel 1, heater 2, water inlet 3, sewage draining exit 4, go out steam port 5, safety valve 7, check valve 8, insulating layer 30, Structure, shape, the connection connection type of cable inlet 31, are not intended to limit, any variations and alternatives expected without creative work, All cover and is within the protection scope of the utility model.
