Description

Refilling device of bubble type container {APPARATUS FOR CHARGING LIQUID OF BUBBLE VESSEL}

The present invention relates to a bubble container, and more particularly, to a bubble container refilling device capable of filling residual chemical solutions in a bubble container into another bubble container.

A bubble vessel is a vessel used to provide a desired amount of chemical solution in a reaction vessel using nitrogen (N 2). Such a vessel can provide the desired amount of chemical solution to the reaction vessel only if the solution in the vessel is maintained at a constant level.

Therefore, conventionally, when a solution in a bubble container falls below a predetermined liquid level (generally 1/5), the supply of the solution is stopped, and a solution in another bubble container is continuously provided to the reaction container. At this time, it is determined that the solution is used up to some extent, that is, a state in which the remaining solution in the replaced container, that is 1/5 or less, but conventionally no method for using such a residual solution has been devised. That is, if the residual solution in the used containers can be transferred to another container, the collected residual solution can be reused, but no separate device is proposed to fill the remaining solution in the used container into another container. Therefore, in the conventional bubble type container, since the remaining solution in the container cannot be used at all, the whole amount is discarded, and there is a problem that the waste of the solution is large and causes one of environmental pollution.

The present invention is to solve this problem, an object of the present invention is to provide a refilling device of the bubble container capable of filling the remaining bubble in the bubble container to another bubble container.

In order to achieve the above object, the present invention provides an apparatus for filling a remaining bubble in a bubble container into a filling bubble container, wherein the bubble container includes a first inlet tube and an internal residual solution in which a predetermined nitrogen can be introduced thereon.

That is, when the predetermined liquid 21 flows in through the inflow pipe 18, the liquid level in the container 12 rises, and the gas in the container 12 will be discharged | emitted through the discharge pipe 19 as the liquid level rises.

The level sensor 22 is attached to the upper part of the container 12, and this level sensor 22 detects whether the solution 21 in the container 12 exists up to the position where the level sensor 22 is attached. To the control unit or display unit.

Hand valves HV3 and HV4 are connected to the inlet pipe 18 and the discharge pipe 19 of the container 12, respectively, and the hand valves HV3 and HV4 are opened and closed by a user's control.

Nitrogen from the nitrogen source, on the other hand, is provided to valves V11 and V12 via supply passage 100, wherein nitrogen from valve V11 is to valve V4 and nitrogen from valve V12 is a hand valve. Is provided in (HV2). Here, the valve V4 is configured between the hand valve HV1 and the intermediate passage 200, and provides the liquid 17 in the container 11 to the intermediate passage 200 in accordance with the opening and closing state thereof.

The supply passage 100 includes a hand valve HV5 as shown, and inflows nitrogen from a nitrogen source as the hand valve HV5 opens and closes, and the introduced nitrogen is checked valve 101, a filter 102. And through the flowmeter 103 to the valves V11 and V12. Such a configuration in the supply passage 100 is not an essential configuration constituting the present invention and only has an auxiliary meaning will be easily understood by those skilled in the art from the following description.

The intermediate passage 200 has a check valve 201 and a filter 202, and nitrogen supplied through the valve V11 or liquid provided through the valve V4 to the valves V2 and V31. to provide. Here, the valve V2 is connected to the hand valve HV3 in the vessel housing 10 described above, and the valve V31 is configured to discharge nitrogen from the intermediate passage 200 to the outside in accordance with the opening and closing thereof.

On the other hand, the hand valve HV4 in the container housing 10 is connected to the valve V32, and the gas from the hand valve HV4 is discharged | emitted to the exterior according to the opening / closing state of the valve V32.

In the drawings, the valves V11 and V12 perform a common function of receiving nitrogen from the supply passage 100, and thus, the valves V11 and V12 are illustrated as a pair using a dotted line. The valves V31 and V32 have a common function of discharging nitrogen to the outside. As shown, a pair is shown using a dotted line.

In addition, PT1 and PT2 refer to a pressure sensor. As will be described later, the pressure sensor PT1 is nitrogen pressure from the valve V12, and the pressure sensor PT2 is nitrogen in the vessel 12. It performs the function of detecting the pressure discharged through.

The process of filling the container 12 with the remaining solution in the container 11 using the apparatus having the above-described configuration will be described below.

First, the first and second containers 11 and 12 are installed in the holders 20 and 30 in the container housing 10, respectively. Then, only the hand valve HV5 and the valves V11 and V31 are opened while all the valves are closed to allow nitrogen from the nitrogen source to be introduced.

The reason for introducing nitrogen in this way is to maintain the cleanliness by washing the gas and liquid passages in the apparatus described above with nitrogen. That is, since nitrogen from the nitrogen source is discharged to the outside through the valve V11, the intermediate passage 200 and the valve V31, impurities in the passage are removed by the nitrogen. This washing process is preferably performed for about 30 minutes.

That is, the cleaning process is performed by opening only the valves HV5, V11 and V31 and supplying nitrogen.

After performing the cleaning process, the valves V11 and V31 are closed and all the hand valves HV1, HV2, HV3 and HV4 in the container housing 10 are opened. With the hand valves HV1, HV2, HV3 and HV4 open, the valves V32, V2 and V4 are opened in the order described and finally the valve V12 is opened. Thus, nitrogen from the nitrogen source is provided in the vessel 11 through the supply passage 100, the valve V12 and the hand valve HV2. Thus, the nitrogen pressure in the vessel 11 is increased so that the liquid 17 in the vessel 11 is provided to the intermediate passage 200 through the hand valve HV1 and the valve V4, and the intermediate passage 200 ) Is provided to the inlet pipe 18 in the vessel 12 via the valve V2, ie the liquid in the vessel 11 is filled into the vessel 12.

During the filling process, when the liquid level of the container 11 is lower than the predetermined level or the liquid level in the container 12 is higher than the predetermined level, the filling process should be finished. The level sensors 16 and 22 described above are used for this purpose. That is, the level sensor 16 detects whether the liquid level in the container 11 is below the position of the level sensor 16 and provides it to the control unit or the display unit, and the control unit / user closes the valve V12 according to this signal / indication. Therefore, the liquid level is discharged from the container 11, and the level sensor 22 detects whether the liquid level in the container 12 is higher than the position of the level sensor 22, and the controller or the user controls the valve according to this signal / indication. Close V12). Therefore, it is possible to prevent the liquid level in the container 11 from being lower than the level sensor 16 or the liquid level in the container 12 from being higher than the level sensor 22.

In addition, when overpressure is sensed by the pressure sensors PT1 and PT2 during the charging process, it means an abnormal state. Therefore, the overpressure state should be released by closing the valves V11 and V12.

When the filling process is completed by the above-described process, that is, when the liquid level in the container 11 is below the position of the level sensor 16 or the liquid level in the container 12 is above the position of the level sensor 22, the valve V12 is closed. Then, the valves V4, V2, and V32 are sequentially closed, and then a cleaning process is performed. That is, by opening only the valves HV5, V11, and V31 and supplying nitrogen, the gas and liquid passages in the apparatus are washed with nitrogen and all processes are completed. This washing process is also preferably performed for about 30 minutes.

Meanwhile, as described above, the valves V11 and V12 are for supplying nitrogen, but the valves V11 are for cleaning and the valves V12 are for supplying nitrogen into the vessel 11. It will be readily appreciated that (V11, V12) should not be opened at the same time.

In addition, the valve (V31) is for discharging nitrogen in the washing process, the valve (V32) is for discharging the nitrogen in the container 12, these valves (V31, V32) should not be opened at the same time It will be easy to see.

As such, the present invention has an effect that the remaining solution in the bubble container can be reused by filling it into another bubble container.
