Description

Transfer pump for deaeration

The present invention relates to a bubble removing transfer pump, and more particularly, to a bubble removal transfer pump having a hopper-shaped transfer tank installed in the vertical direction.

Transfer pumps are used to transfer or separate raw or mined minerals from paper mills, mines or gold mines that carry abrasive fluids containing abrasive materials such as slurry, sand and limestone.

Such a transfer pump has a problem in that, when bubbles or bubbles are included in the fluid during the transfer or separation process, a cavitation occurs, which damages the impeller and the impeller case mounted on the transfer pump and degrades the pumping performance.

However, the horizontal centrifugal volute type pump mainly used in the related art has been difficult to remove bubbles generated during the transfer or separation process.

The present invention is to solve the above problems, it is an object of the present invention to provide a bubble removal transport pump that can effectively remove the bubbles or bubbles generated in the process of transporting or separating the fluid.

The above object of the present invention, the motor; A transfer tank having a top and bottom narrow hopper shape each having an upper fluid suction port, a bubble discharge port, and a lower fluid passage; A rotating shaft penetrating the transfer tank up and down and having a lower end positioned in the fluid passage, and rotated by a motor; An impeller having a plurality of horizontal guide vanes, the center portion of which is coupled to the lower end of the rotating shaft; An impeller case having a fluid discharge port at one side, the impeller case being coupled to a lower end so as to communicate with the fluid passage of the transfer tank and accommodating the impeller; It is achieved by providing a bubble pump transfer pump configured to include.

In another aspect of the invention, the motor may be connected to the rotating shaft by a coupling or by a pulley and a belt.

In another aspect of the present invention, a housing is installed on the transfer tank, a plurality of rotary shaft support bearings may be installed inside the housing.

In another aspect of the present invention, the bubble receiving tank connected to the bubble outlet on the upper side of the transfer tank may be installed.

In another aspect of the present invention, the fluid overflow prevention plate may be installed in the interior of the transfer tank above the bubble outlet.

The bubble pump transfer pump according to the present invention is the fluid flows downward along the inner wall of the transfer tank formed in the vertical direction to remove some of the bubbles contained therein, the remaining bubbles and bubbles are separated through the impeller By discharging through the bubble discharge port formed on the upper side of the transfer tank there is an effect that can minimize the cavitation.

In addition, by installing a bubble receiving tank on one side of the transfer tank there is an effect that can be easily beneficiated and recycled light ore mixed in the upper surface of the bubbles gathered into the bubble receiving tank through the bubble outlet. In particular, high levels of recycling can be expected when transporting materials such as pulp, which generate large amounts of suspended solids.

Figure 4 is a front view of the bubble pump transfer pump according to another embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view of a bubble removing transfer pump according to an embodiment of the present invention, Figure 2 is a side view of Figure 1, Figure 3 is a cross-sectional view of FIG.

As shown in Figures 1 to 3, the bubble removal conveying pump according to an embodiment of the present invention, the motor 10, the fluid suction port 31 is installed in a vertical direction with respect to the ground and inclined upwardly; The upper and lower narrow hopper-shaped transfer tank 30 having a bubble discharge port 32 and a fluid passage 34 formed at a lower end thereof, and a lower portion of the fluid passage 34 of the fluid passage 30. Rotation shaft 20 is fixed to the position and is vertically connected to the motor 10 through the coupling (11) is rotated by the transmission of power, and the center impeller 40 is installed to be coupled with the lower end of the rotation shaft (20) And an impeller case 50 having a fluid discharge port 51 provided with a valve 52 at one side thereof and coupled to a lower end thereof so as to communicate with the fluid passage 34 of the transfer tank 30 and accommodating the impeller 40. It is configured to include.

The impeller 40 has a plurality of horizontal guide vanes 41, and the horizontal guide vanes 41 are installed inside the impeller case 50 so as to face upward in a direction opposite to the moving direction of the fluid.

The fluid intake prevention plate 33 for preventing the fluid from overflowing the transfer tank 30 when the intake amount of the fluid is larger than the discharged upper portion of the fluid inlet 31 and the bubble outlet 31 into the transfer tank 30. ) Is installed, the upper side of the transfer tank 30 may be installed in the bubble receiving tank 80 to be connected to the bubble outlet (32). At this time, the through hole 33a is formed in the center of the fluid overflow preventing plate 33 so that the rotating shaft 20 penetrates.

In addition, a housing 60 is installed on the transfer tank 30, and a plurality of rotary shaft support bearings 61 for rotatably supporting the rotary shaft 20 are installed inside the housing 60 to rotate the rotary shaft 20. Vibration can be minimized.

Reference numeral 81 denotes a discharge pipe connected to the bubble receiving tank 80 to discharge the bubbles and bubbles when the bubble is filled in the bubble receiving tank 80, and 70 is a support coupled to the side of the transfer tank 30. Indicates.

Referring to the operation of the bubble removal transfer pump according to an embodiment of the present invention configured as described above are as follows.

The fluid introduced through the fluid suction port 31 of the transfer tank 30 is coupled to the lower end of the transfer tank 30 through the fluid passage 34 along the inner wall of the inclined transfer tank 30. Flows into the inside of the air, and at this time, some of the bubbles contained in the fluid flow down to the bottom of the transfer tank 30 due to an increase in the fluid movement speed resulting from the difference in the vertical cross-sectional area of the transfer tank 30. .

Then, when the rotating shaft 20 is rotated by the operation of the motor 10, the impeller 40 installed inside the impeller case 50 rotates together, and light bubbles or bubbles contained in the fluid move upwardly to the transfer tank 30. The fluid that floats and is bubbled as above is discharged out through the fluid outlet 51.

Some of the bubbles that emerged are naturally burst or removed from the inside of the transfer tank 30, the bubbles and bubbles not removed through the bubble outlet (32) formed on the upper side of the transfer tank (30) 80, which is contained in the bubble receiving tank 80 may contain some of minerals such as carbon depending on the fluid to be transported, and these minerals may be separately collected and then recycled as resources.

On the other hand, in the case of the structure that connects the motor 10 to the rotary shaft 20 and the coupling 11 as in one embodiment, there is a hassle to change the outer diameter of the impeller 40 in order to change the delivery amount of the transfer pump. .

Figure 4 shows a bubble removal conveying pump according to another embodiment of the present invention, the motor 10 is configured to be connected by the rotating shaft 20, the pulley 12 and the belt 13 impeller 40 By simply changing the diameter of the pulley 12 installed on the upper end of the rotary shaft 20 without changing the outer diameter of the change the rotational speed of the motor 10 transmitted to the rotary shaft 20 to easily control the amount of delivery of the transfer pump Can be.

Although the present invention has been described above with reference to specific embodiments, it is not necessarily limited thereto, and modifications and variations may be made without departing from the scope of the present invention.
