Description

CONTROL METHOD OF REUSE DEVICE OF WASHING WATER FOR DEVELOPING MACHINE}

The present invention relates to a recycling apparatus and a control method of the flushing water for the film developer, and more particularly, by recycling the flushing water used in the film developing machine, it is easy to save the washing water and discharge the amount of water to the sewage, etc. The present invention relates to a recycling apparatus and a method of controlling the same, which can be used to reduce water pollution.

In general, the flushing water is to wash out the developer in the photo paper, which is developed in close contact with a medical X-ray film developing machine, an automatic developing machine, a manual developing machine, a general photo developing machine, a printing plate photo developing machine, and the like.

In addition, conventionally, since the used washing water is discharged as sewage, water pollution is caused, and thus a device capable of recycling the water is required.

Accordingly, it is conventionally filed and disclosed as a 'flush washing machine for film developer' of Patent No. 10-1999-3812, and a conventional flushing water recycler is distributed to a lower end of a reservoir for storing flush water used in a film developing machine. A pipe for the pipe, a pump inlet pipe on one side of the distribution pipe, a drain pipe and a drain valve on the other side of the distribution pipe, and a pump connected between the pump inlet pipe and the pump discharge pipe. Install a valve in the discharge pipe, connect a filter between the pump discharge pipe and the filter discharge pipe, install another distribution pipe at the tip of the filter discharge pipe, and install a waste water pipe and a wastewater valve on one side of the distribution pipe. On the other side, the recycling pipe and recycling valve are installed on the other side.

In the conventional film developing flusher recycling machine made in this way, the flushing water used in the film developing machine usually leads to a pipe via a reservoir → a pump → a filter and flows into the film developer in the pipe to recycle the flushing water.

In the wastewater treatment, the recycling valve is closed and the wastewater valve is opened to supply wastewater to a separate wastewater tank via the wastewater valve by the power of the pump.When the pump fails, the wastewater is opened by opening a drain valve installed in the reservoir. Can be supplied to the barrel.

Furthermore, the conventional flushing water recycling machine for film developing machine can automatically recycle the flushing water used in the film developing machine by operating the pump in conjunction with the solenoid valve on the film developing machine side.

However, since the conventional film developing washing machine recycling machine cannot automatically warn of failure of the pump or deterioration of the filtration capacity of the filter, there is a disadvantage that it is inconvenient for the user to always check the failure of the pump or the performance of the filter. .

In addition, in the conventional state, since the flow rate forcibly transferred by the pump is larger than the amount of flush water naturally discharged from the film developer, not only is it difficult to automate, but also a lot of idling of the pump occurs, which reduces the pump life. Bubbles may be generated in the wash water that is introduced into the film developer and recycled when the water is not filled in the tank. There is a further disadvantage that the wash water used in the film developing machine can be easily overflowed in the reservoir when it is small, so that it is difficult to automate.

Furthermore, in the related art, since the circulating water is automatically filtered and circulated by interlocking with the solenoid valve of the film developing machine, an additional connector or the like is required separately from the installed solenoid valve of the film developing machine. There is another disadvantage of not being able to.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention can be easily installed by anyone by connecting to the hose for discharging the flushing water from the film developer to recycle the flushing water used in the film developer. In addition, it is possible to reduce the amount of water flushed out to the sewer, and to easily save the washing water, and to provide a recycling apparatus and a control method of the flushing water for film development that can easily reduce water pollution. In particular, an object of the present invention is to provide a control method that can be realized by smoothly supplying the flushing water by preventing the pump idle, and easy to realize the automation of the warning of the degradation of the motor performance and the reduction of the filtration capacity of the filter. have.

BEST MODE Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 and 2 is a view showing an example of a recycling apparatus for washing water for film developing according to the present invention, the recycling apparatus for washing water for film developing according to the present invention is a medical X-ray (X-ray) film developing, automatic To filter and recycle the flushing water flowing out of the film developing unit 1, such as a developing unit, a manual developing unit, a general photo developing unit, a printing plate developing unit, and the like, and reference numeral 1 denotes a recycling apparatus.

In the recycling apparatus 10 according to the present invention, a pump 12 is installed in a first storage tank 11 that stores and flushes water from the film developing unit 1, and between the pump 12 and the filter 13. And a first valve 15 communicating with each other between the filter 13 and the second storage tank 14 by a hose, and intermittently flushing the water flow between the film developer 1 and the first storage tank 11. And a second valve 16 for controlling a water flow between the second storage tank 14 and the film developing unit 1, and an agent for regulating the supply of supplementary flush water flowing into the second storage tank 14. Each of the three valves 17 is installed.

In the present invention, by installing a fourth valve 18 for discharging the lower flush water in the second storage tank 14 to the outside to discharge the flush water to the outside to clean the recycling apparatus 10, the first The first limit switch 19 and the second limit switch 20 are installed in the storage tank 11, and the third limit switch 21 is installed in the second storage tank 14.

Here, the first storage tank 11 stores the flush water flowing out of the film developing device 1, and the pump 12 forcibly transfers the flush water in the first storage tank 11, The filter 13 is to filter the flushing water transferred from the pump 12, the second storage tank 14 stores the flushing water filtered by the filter 13 and back to the film developer (1) It is leaking.

In addition, the first limit switch 19 detects the water level of the flushing water which locks the lower end of the inlet of the pump 12 to the flushing water in the first storage tank 11 to supply power to the pump 12. As a result, the inlet of the pump 12 is sufficiently immersed in the flushing water to facilitate the forced transfer of the flushing water.

The second limit switch 20 is connected to a warning sound, that is, the alarm generator 20a by detecting a dangerous water level overflowing the water in the first storage tank 11, and can emit an alarm light in addition to the alarm generator 20a. Self-explanatory

The third limit switch 21 detects the level of the wash water that can be supplied to the film developing unit 1 in the second storage tank 14 so that the indicator 21a emits light. This is because the washing water can be smoothly supplied to the film developing device 1 when the amount of washing water sufficient in the step 14) is stored.

In the present embodiment, in order to efficiently configure the recycling apparatus 10, two diaphragms 10b and 10c are installed in the main body 10a, and the second storage tank 14 is disposed on the diaphragm 10b. The filter 13 is installed in the diaphragm 10c.

In addition, in the present embodiment, the first safety valve 22 is installed between the second valve 16 and the second storage tank 14, and between the fourth valve 18 and the second storage tank 14. It is obvious to install the second safety valve 23 in the valve.

Thus, the recycling apparatus for film developing water for washing according to the present invention opens the first valve (15) to introduce the flushing water flowing out of the film developing device (1) into the first storage tank (11). 1 When the water level of the flushing water in the storage tank 11 is increased and the first limit switch 19 is operated, the pump 12 is operated to forcibly transfer the flushing water in the first storage tank 11. When the water flushed is filtered by the filter 13 and flows into the second storage tank 14, and the water level of the flushing water flowing into the second storage tank 14 is increased to operate the third limit switch 21. The indicator 21a indicating the light is emitted, and thus the user returns the filtered flush water to the film developer 1 by recycling the second valve 16.

However, when the flushing water in the first storage tank 11 is not easily moved due to the failure of the pump 12 or the deterioration of the filter 13, the first valve 15 flows into the first storage tank 11. When the amount of the flushing water to be more than the amount of flushing water flowing out of the first storage tank 11, the level of the flushing water in the first storage tank 11 is continuously increased to raise the second limit switch 20. It will be activated and a warning sound or alarm will sound.

At this time, the user can check the pump 12 and the filter 13 to take action.

On the other hand, if there is a limit in the recycling of the flushing water, the fourth valve 18 is opened, and the pump 12 is manually operated continuously. The film developing apparatus 1, the first storage tank 11, and the second storage tank 14 ) The flushing water in the tank can be completely discharged.

If the flushing water level in the second storage tank 14 does not rise even though the pump 12 continues to operate for a long time, or the flushing water rise in the second storage tank 14 is smooth. If not, since the washing water is insufficient, the third valve 17 is opened to replenish the washing water.

Thus, the recycling apparatus for the film developer for washing water of the present embodiment can be easily filtered and recycled.

Meanwhile, in the present invention, the recycling apparatus for the film developer washing water can be automatically operated. As another example, as shown in FIG. 3, first, second, third and fourth solenoid valves which electronically operate the valve and the like. The valves 15a, 16a, 17a, and 18a can be improved and automatically controlled by the controller 24, so that the controller 24 receives signals from the first, second and third limit switches 19, 20 and 21. And the first, second, third and fourth valves 15a, 16a, 17a, and 18a and the pump 12 are controlled.

That is, in the recycling apparatus for the film developer washing water of the present embodiment, the flush water flowing out of the film developer 1 is introduced into the first storage tank 11 by the first valve 15a, and the first storage tank is interposed. The flushing water in (11) is forcibly transferred by the pump 12, filtered by the filter 13, then transferred to the second storage tank 14, the flushing water stored in the second storage tank 14 film The reflow of the developer 1 is interrupted by the second valve 16a, and the inflow of the flush water replenished with the second storage tank 14 is interrupted by the third valve 17a. The first limit switch 19 is operated when the flushing water level of the storage tank 11 is an intermediate level, and the second limit switch 20 is activated when the flushing level of the first storage tank 11 is an upper level. The third limit switch 21 is operated when the flushing water level of the second storage tank 14 is an intermediate level The machine 24 receives the signals of the first, second and third limit switches 19, 20 and 21 to individually separate the pump 12 and the first, second, third and fourth valves 15a, 16a, 17a and 18a. In addition to operating the alarm, the beeper and warning light are selectively operated.

In addition, in the present embodiment, the alarm generator 20a for generating a warning sound, the indicator 21a for emitting light by the signal of the third limit switch 21, and the power indicator 25a for emitting light in response to the signal of the power switch 25. Is obviously connected to the controller 24.

The method of controlling the recycling apparatus for washing water for film developing according to the present embodiment as described above will be described in detail with reference to FIGS. 4 and 5.

In the control method of the present invention, the pump 12 is operated when the level of the first storage tank 11 is raised to operate the first limit switch 19.

That is, when the power switch 25 is turned on, the first valve 15a is opened by the signal of the controller 24, and the water washing in the film developing device 1 is carried out through the first valve 15a. Flows into (S10).

When the wash water flows into the first storage tank 11, the operation of the first limit switch 19 is determined (S20). When the first limit switch 19 is turned on, the pump 12 is operated to store the first water. The flushing water in the tank 11 is transferred to the second storage tank 14 (S30).

In addition, the control method of the present invention flows into the first storage tank 11 by blocking the first valve 15a when the water level of the first storage tank 11 rises to operate the second limit switch 20. In addition to blocking the flushing water in the film developing device (1), while stopping the operation of the pump 12, one or more of the warning sound and warning lights are operated.

In other words, if the flushing water in the first storage tank 11 does not flow smoothly due to the failure of the pump 12 or the performance of the filter 13, the level of the flushing water in the first storage tank 11 is increased. In this case, it is determined whether the second limit switch 20 is on (S40). If the second limit switch 20 is on, the first valve 15a is shut off, the pump 12 is stopped, and the alarm is turned on. Will be generated (S41).

In addition, when the second limit switch 20 is turned off in the step S40, it is determined whether the third limit switch 21 is on (S50), and when the third limit switch 21 is on, the second valve 16a is turned on. ) To flush the flushing water in the second storage tank 14 to the film developer 1 (S60), and when the third limit switch 21 is off, the second valve 16a is blocked or blocked. It will be maintained (S51).

Meanwhile, in the control method of the present invention, when the first limit switch 19 and the third limit switch 21 are turned off, the third valve 17a is opened to transfer the supplementary flushing water to the second storage tank 14. It will be replenished with water supply.

That is, as shown in Figure 5, if the first limit switch 19 does not operate in the step (S20) it is determined whether the third limit switch 21 is on (S21), the third limit switch 21 If the third solenoid valve 17a is blocked or maintained in a closed state (S22), and if the third limit switch 21 is off, the third solenoid valve 17a is opened to open the second storage tank ( 14) to wash the water in (S52).

Of course, as described above, it is obvious that the water flush can be completely replaced by opening the fourth valve 18a.

Thus, the recycling apparatus and the control method of the film developer for washing water in accordance with the present invention can easily recycle the wash water used in the film developing.

As described above, the method of controlling the recycling apparatus for the film developer washing water according to the present invention is pumped by the operation of the first limit switch and prevents the overflow of the second storage tank by the operation of the second limit switch. Anyone can install it easily by connecting the hose which discharges the flushing water from the film developer by smoothly flowing the flushing water by the operation of the limit switch, so that anyone can install it easily. In addition to the savings, the amount of water discharged to the sewer can be reduced, so that water pollution can be easily reduced.

In particular, since the control method of the present invention can be easily connected to the flush water discharge hose installed in the film developing machine, anyone can easily install and use it, and can prevent the pump from idling and transfer it without air in the hose. As a result, a smooth supply of the flushing water is realized, and since there is an easy warning about the deterioration of the motor performance and the deterioration of the filtration capacity of the filter, there are further advantages such as easy automation.
