Description

Anti-foaming device for rolling oil cleaning solution {APPARATUS FOR PREVENTING FORMING OF BUBBLES IN OIL DETERGENT LIQUID RETURN TANK}

The present invention relates to an antifoaming device for rolling oil cleaning solution, and provides an apparatus capable of preventing bubbles generated by a dropping vehicle while the alkaline cleaning solution falls from the cleaning tank to the solution storage tank.

In general, since the cleaning solution for cleaning the rolled oil is used while being circulated through the solution storage tank 1 as shown in FIG. 1, the solution 3 is returned from the cleaning tank to the solution storage tank 1 so that the dropping difference in the tank may be reduced. Foam is generated by the foam is discharged out of the storage tank (1) through the foam outlet (2) to remove the foam by the spraying device for removing bubbles (4) or periodically put a defoamer to prevent foaming To prevent it.

However, this method increases the waste of the solution and there is a risk that the operator can slip due to the solution to contaminate or push the surrounding environment as the foam is pushed out of the tank. In addition, when a large amount of antifoaming agent is used to prevent foaming, there is a problem in that the degreasing ability is low and the solution concentration must be increased or the solution must be frequently exchanged, thereby increasing the solution consumption.

The present invention has been made to solve the above problems, it is an object of the present invention to provide a device that can effectively prevent the generation of bubbles by eliminating the drop of the solution returned to the storage tank (1).

The present invention for achieving the above object is that the load of the accumulated solution when the solution (3) is returned to the float pipe 12 through the solution inlet pipe 11 to eliminate the distance that the cleaning solution falls into the storage tank As the float pipe 12 is gradually lowered according to the anti-foam device designed to be discharged to the lower part of the storage solution, the float pipe 12 and the float to temporarily accumulate the solution (3) flowing into the solution inlet pipe (11) It is provided with a solution foam prevention device characterized in that the spring 13 for supporting the pipe is installed and the adjusting shaft 18 and the adjusting plate 17 for adjusting the pressure of the spring 13 is installed.

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

Figure 2 is a longitudinal sectional view of the anti-foaming device according to the present invention, Figure 3 is a perspective view of the anti-foaming device according to the present invention, Figure 4 is an installation state of the device, Figure 5 is an enlarged excerpt of the main portion of the device. The same parts as in the conventional apparatus will be described with the same reference numerals.

The present invention does not directly drop the solution returned to the storage tank (1) from the cleaning tank storage tank (1), the storage tank so that it is discharged to the tank bottom through the solution outlet (14) of the solution inlet pipe (11) 1) It is installed from the lower side to the return pipe, the solution inlet pipe 11 inside the float pipe 12 and the spring 13 which can be moved up and down gradually in accordance with the load of the solution is installed, the float pipe The adjustment shaft 18 which can adjust the height of (12) and the adjustment plate 17 which moves up and down along this adjustment shaft 18 are provided. In addition, the through-holes 15 and 16 are drilled in and out of the float pipe 12, and the pressure between the float pipe 12 and the adjusting shaft 18, the float pipe 12 and the solution inlet pipe 11 by the pressure of the solution. In order to reduce the friction of the adjusting shaft 18, the adjusting shaft 18 and the adjusting plate 17 in the form of male and female screws as shown in Figure 5 so that the adjusting plate 17 can move up and down by the rotation operation of the adjusting shaft 18. Combining, the solution outlet 14 of the solution inlet pipe 11 is configured in the form of the upper and lower deposits so that the discharge of the solution increases while going down.

According to the present invention configured as described above, when the upper end of the float tube 12 is adjusted to match the solution inlet tube 11 by rotating the adjusting shaft 18, the returned solution 3 gradually enters the float tube 12. While the float tube 12 is gradually lowered by the load of the solution according to the solution inflow amount, the introduced solution is discharged to the storage tank 1 through the solution outlet 14 formed in the lower portion. In addition, as the float pipe 12 descends below the solution inlet pipe 11, the discharge of the solution through the outlet 14 increases, and the spring 13 when the flow rate of the solution flowing into the inlet pipe 11 decreases. The float pipe 12 gradually rises up by the pressure of), that is, the float pipe 12 operates up and down in accordance with the inflow amount, thereby automatically adjusting the solution discharge rate.

As described above, the present invention discharges the solution to the lower portion of the storage tank 1 while the return solution to the storage tank 1 is adjusted by the solution pressure flowing into the float tube 12. It provides a useful effect that can effectively prevent the occurrence.
