Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsion mixing pump, and more particularly to a mixing pump which mixes water and fuels to form an emulsion without the need for a separate power means.

[0002]

2. Description of the Related Art A conventional emulsion mixing pump is disclosed in Korean Patent No. 84-1528, which includes a gear pump, a plurality of impellers, and a plurality of horizontal holes horizontally between them. It is configured by installing a fixed plate on which is formed and installing another drive motor outside to drive the gear pump and the impeller.

[0003]

However, in such a conventional emulsion mixing pump, a separately installed drive motor rotates a gear pump and a plurality of impellers, so that the drive motor consumes more electric power. However, there was a problem that the unit price of production increased incidentally.

In addition, since the fuel and water are mixed by the wing curved horizontally in the impeller and the horizontal hole formed horizontally in the fixed plate, the mixed water and fuel are separated again. Tended to be.

In particular, since there is not enough control device to keep the amount of water input at a constant ratio depending on the amount of fuel used, the ideal amount of water for the emulsified fuel is not always maintained, so that the efficiency is improved. In terms of aspects, it is a fact that it has not yet been put to practical use because it has major problems.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and it is a first object of the present invention to provide a mixing pump for mixing water and fuels and emulsifying them without the need of another power means. To aim.

A second object of the present invention is to provide an emulsion mixing pump which always keeps a constant amount of water input depending on the amount of fuel used.

[0008]

In order to achieve the above first object, the present invention provides an emulsion mixing pump having a plurality of impellers installed in a main body, which is sandwiched in a space of the main body and is provided on one side of a shaft. A plurality of grooves are formed on the outer surface of the combined rotating disk, and a vane pump in which a vane is sandwiched in each groove and side surfaces of a plurality of mixing impellers that are installed in the main body and are connected to a shaft. An inclined wing is formed to be inclined, a plurality of inclined holes is formed to be inclined on a side surface of the mixer installed between the mixing impellers, and a feeding impeller connected to a shaft is provided on a side of the mixer. An emulsion mixing pump comprising:

In order to achieve the above second object, the present invention provides
Provided is an emulsion mixing pump, characterized in that a jet pump including a trumpet-shaped diffuser and a nozzle at a lower end thereof is installed between a vane pump and an impeller installed in the main body.

[0010]

According to the mixing pump of claim 1, the fuel flowing into the vane pump receives a rotational force to rotate the mixing impeller and the feed impeller connected to the shaft of the vane pump, and then passes through the impeller. Mixed with water. The fuel and water that enter the impeller pass through the inclined wings of the mixing impeller and the inclined holes of the mixer, which are rotated by the rotational force of the vane pump, and thus the finely divided fuel particles and water particles are mixed and trapped. To be done.

According to the second aspect of the invention, the fuel entering the impeller draws in water in an amount corresponding to the amount of passage while passing through the jet pump, and is mixed with this water as described above. The quantity is always kept constant with respect to the fuel.

According to the third aspect of the present invention, after being mixed as described above, it is fed to the burner by the feeding impeller.
Fuel combustion is accelerated.

Embodiments of the present invention having the above-mentioned features will be described in detail below.

As shown in FIGS. 1 to 4, the emulsion mixing pump according to the present invention comprises a main body 10, a vane pump 20 and an impeller 30 on the inner surface thereof, and a jet pump 40 installed between the vane pump 20 and the impeller 30. Equipped with.

A fuel inlet 11 and a fuel outlet 12, a water / oils inlet 13 and a water / oils outlet 14 are formed in the body 10, for example, a cylindrical body 10.
A shaft 15 is rotatably installed in the center of the main body 10 in a lateral direction, and a space portion 16 in which a vane pump 20 described later is installed is formed on an inner surface of the shaft 15.

The vane pump 20, as shown in FIG.
In the space 10 of the main body 10, a rotary disc 21 which is penetrated by a shaft 15 and sandwiched is installed, and a plurality of grooves 22 are formed radially on the outer surface of the rotary disc 21 at regular intervals from the center thereof. However, a vane 23 is sandwiched in each groove 22. In the present invention, the vane pump (20) is illustrated as a non-deflecting type, but the present invention is not limited to this and may be a deflecting type.

As shown in FIG. 3, the impeller 30 includes a plurality of mixing impellers 31 installed on the inner surface of the main body 10, for example.
An inclined wing 32 inclined at a predetermined angle with respect to a center line is formed on the outer surface of the mixer, and a mixer 33 is installed between the mixing impellers 31. The mixer 33 has an inclined hole 34 inclined at a predetermined angle.
Is formed, and the feeding impeller 35 is installed in the rear of the above.

In the present invention, it is desirable that the inclination angle of the inclined wings 32 is 30 °, the inclination angle of the inclined holes 34 is 15 °, and the number of the inclined holes 34 is 160.

The jet pump 40 has, for example, a trumpet diffuser 41 and a nozzle 42 installed at the inlet 13 for mixing water and oils, and a check valve 43 and a water valve provided on one side of the nozzle 42 for allowing only the inflow of water. It is constituted by forming the passage 44.

The emulsion mixing pump according to the present invention is installed between the pump 7 and the burner 8 (see FIG. 4).
An unexplained reference numeral 9a in the drawings is a control valve.

The operation of the present invention will be described in detail below with reference to FIGS.

As shown in FIG. 4, before the fuel forcibly pushed by the refueling pump 7 installed in the existing boiler reaches the adjusting valve 9a, the vane pump 20 installed inside the main battery 10 through the fuel inlet 11 is provided. The fuel entering the vane pump 20 receives the rotational force to rotate the mixing and pushing impellers 31 and 35 connected to the shaft 15 of the vane pump 20, and the fuel exiting through the fuel outlet 12 of the vane pump 20 is adjusted. Only the required amount is sent to the burner 8 through the valve 9a, and the remaining amount of fuel is restored.

The fuel introduced into the burner 8 through the adjusting valve 9a is mixed with water by drawing in the water while passing through the jet pump 40 before reaching the burner 8, and is then rotated by the rotational force of the vane pump 20. Enter the mixing impeller 31. At this time, the mixture (fuel + water) is in the form of finely divided fuel particles and water particles while repeating the passing process of the inclined wings 32 of the mixing impeller 31 and the inclined holes 34 of the mixer 33 several times. . Here, the mixture in which the fuel particles are trapped on the surface of the water particles or the water particles are trapped on the surface of the fuel particles is fed to the burner 8 by the feed impeller 35.

When the water particles and the fuel particles are mixed in such a state that they are trapped in each other and enter the burner 8, the oxygen contained in the water accelerates the combustion of the fuel and suppresses the generation of non-combustible gas. Increase.

[0025]

As described above, according to the emulsion mixing pump of the present invention, the combustion of fuel is promoted and the generation of non-combustible gas is suppressed, so that the thermal efficiency is increased. Therefore, it has a useful effect not only in saving fuel but also in preventing industrial pollution.
