Description

The fuel supply system of rotation vaporizing burner

The utility model relates at boiler and uses 4kgf/cm with rotation in the vaporizing burner ²During the electronic pump of above high pressure, can handle the fuel supply system of the rotation vaporizing burner of the air in fuel conduit when igniting initial stage and burning naturally.

The employed burner of domestic boiler, in short-term or the water in the airtight tank body of certain hour heating make burnings such as fuel for indoor greenhouse and use hot water.

Fuel is supplied with usually and is passed through cartridge from fuel tank, and behind oil filter and oil pressure pump or electronic pump, order is delivered to burner and combustion chamber.

Thereby above-mentioned electronic pump extracts the fuel supplied burner from fuel tank, and this burner is not only with the fuel initial ignition that provides, and it is burnt sustainedly and stably.

In the said burner kind, the rotation vaporizing burner is used to oil burning boiler, the stability when utilizing the ultrasonic vibration sprayer that is arranged at the auxiliary fuel jar on the burner combustion part to maintain igniting when initial ignition.

The fuel supply system of rotation vaporizing burner in the past, as shown in Figure 1, outlet at level pressure electronic pump (1) is provided with nozzle carrier fixing body (2), connects the copper pipe (4) of certain-length in the outlet of this nozzle carrier fixing body (2), and injected limit, fuel limit is discharged from.Owing to be provided with nozzle (3) in the inherent upper end of said nozzle seat fixing body (2), thereby, produce the shortcoming that flame is swung because of gassing thereupon using by electronic pump (1) under the situation of kerosene.

Promptly, 20, in the low capacity of 000kcal/h, since can not the limit nozzle (3) burner oil in the nozzle carrier fixing body (2), the air of upper part is handled on the limit, therefore flame vibration, this be because from electronic pump (1) to nozzle (3) pressure height gassing not, and begin while spraying to mix with air thereby discharge bad from said nozzle (3).

Thereby the utility model considers not only not make bubble infiltrate fuel conduit in order to solve shortcoming as described above, even and then bubble infiltrate fuel conduit and also can discharge rapidly, but also consider stability.

The purpose of this utility model is to provide a kind of nozzle carrier fixing body that will be connected in level pressure electronics delivery side of pump with the copper pipe of certain-length to carry out numerous variations, make the fluid velocity that ejects from spray nozzle front end not on the same line of above-mentioned copper pipe, after impacting deceleration on the nozzle wall surface of said nozzle seat fixing body, because collecting naturally, its fluid flows, thereby not only obtain certain flow, and do not make bubble infiltrate fuel conduit, even bubble is sneaked into the fuel supply system of the rotation vaporizing burner that fuel conduit also can discharge rapidly.

The fuel supply system of rotation vaporizing burner of the present utility model to achieve these goals is characterized in that: in the outlet of the level pressure electronic pump (11) that passes through oil filter (10), copper pipe (14) by certain-length is provided with nozzle carrier fixing body (12), in this nozzle carrier fixing body (12) inside, be provided with by the fixing nozzle (13) of the O type circle (16) of central authorities, form the jet space (17) of different said nozzles (13) and the fuel discharge outlet (18) of nozzle carrier fixing body (12).

Fig. 1 is a profile of showing the fuel supply system of rotation vaporizing burner in the past.

Fig. 2 is a profile of showing the fuel supply system of the rotation vaporizing burner that relates to embodiment of the present utility model.

Fig. 3 is the profile of another form of showing the fuel supply system of rotation vaporizing burner of the present utility model.

Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.

Fig. 2 is a profile of showing the fuel supply system of the rotation vaporizing burner that relates to embodiment of the present utility model, and the fuel supply system of rotation vaporizing burner of the present utility model uses 4kgf/cm when going up at rotation vaporizing burner (not shown) ²During the electronic pump of above high pressure (11), owing to form jet space (17) center of different nozzles (13) and fuel discharge outlet (18) center of nozzle carrier fixing body (12), thereby when initial ignition and burning, can handle the air in fuel conduit naturally.

Inlet at the electronic pump (11) of above-mentioned high pressure connects oil filter (10), and connects certain-length in the exit

Font copper pipe (14), the nozzle carrier fixing body (12) that this copper pipe (14) is connected in inlet is a cuboid, forms fuel discharge outlet (18) in a central side.Go up to be provided with by the fixing nozzle (13) of the O type circle (16) of central authorities at this nozzle fixing body (12), it is formed with (17) center, space of the different fluids (15) that eject from said nozzle (13) and fuel discharge outlet (18) center of said nozzle seat fixing body (12).

The fuel supply system of the present utility model of Gou Chenging turns round if pass through oil filter (10) electronic pump (11) as described above, and then fluid moves along copper pipe (14), and the nozzle (13) from nozzle carrier fixing body (12) ejects.

At this moment, because the speed of the fluid (15) that ejects from nozzle (13) is not certain value, thereby on the wall of said nozzle seat fixing body (12), fluid is injected in the space (17), naturally after underspeeding, the fluid limit is full of limit, above-mentioned space (17) and moves to fuel discharge outlet (18) naturally.

Thereby, as mentioned above, because jet space (17) center of each self-forming jet blower (13) and fuel discharge outlet (18) center of said nozzle seat fixing body (12), therefore discharge air naturally by the fuel discharge outlet (18) of said nozzle seat fixing body (12), not only flame is not swung on rotation vaporizing burner (not shown), and can obtain stable flame.

Fig. 3 is the figure of another form that shows the fuel supply system of rotation vaporizing burner of the present utility model, forms the center of different nozzle (13) and nozzle carrier fixing body (12) respectively.Nozzle carrier fixing body (12) shown in Fig. 3 (A), identical with nozzle carrier fixing body (12) shown in Figure 2, it is fuel discharge outlet (the 18 ') difference of directly installing, structure of the nozzle carrier fixing body (12) of collecting fluid (15) is set for it and in the hole of side, fuel is gone up at fuel discharge outlet (18 ') and flowed out.

Nozzle carrier fixing body (12 ') shown in Fig. 3 (B), identical with nozzle carrier fixing body (12) shown in Figure 2, just do not have fuel discharge outlet (18), and only form hole (19), it is provided with the structure of the nozzle carrier fixing body (12) of collecting fluid (15) and the hole of side is flow through fuel.

Different therewith, nozzle carrier fixing body shown in Fig. 3 (C) (12 "); with nozzle carrier fixing body (12; the 12 ') difference shown in Fig. 2 and Fig. 3 (A), (B); in a straight line; the epiphragma that is provided with mesh epiphragma (20) or does not have mesh in the space (17) between nozzle (13) and nozzle carrier fixing body (12 ") obtains certain flow with the control flow velocity with the entrance and exit setting.

As mentioned above, if employing the utility model, then can provide a kind of making various changes to be arranged with the nozzle carrier fixing body of the copper pipe connection of certain-length in level pressure type electronic pump outlet, make the speed of the fluid that ejects from spray nozzle front end and above-mentioned copper pipe not on same line, after impacting deceleration on the nozzle wall surface of said nozzle seat fixing body, because can collect this fluid flows naturally, thereby not only obtain certain flow, and can not make bubble sneak into fuel conduit, even bubble is sneaked into the fuel supply system of the rotation vaporizing burner that fuel conduit also can discharge rapidly.
