[0002]

In the processing of photographic light-sensitive materials such as color photographic light-sensitive materials, X-ray films and printing films,
Since the photographic waste liquid generated by the development process contains various pollutants, it cannot be discharged as it is to sewage. Therefore, we have outsourced the collection of waste liquid to a collection company, but recently, by concentrating photographic waste liquid with a vacuum heat pump-type evaporative concentrator with high processing capacity per hour, it is possible to simplify waste liquid handling and reduce transportation costs. Has been done. On the other hand, the amount of waste liquid for small-scale users is 1
In the small automatic development processing apparatus which is as small as about 0 liter / day or less, there is a demand for a small automatic development processing apparatus which can be built in the automatic development processing apparatus and can be downsized at a low cost without increasing the installation space. In this case, there is also proposed a waste liquid evaporative concentration processing device that uses the exhaust air from the drying section of the automatic development processing device.

[0003]

In such an automatic photographic processor for photography, the amount of water used recently has decreased, but it is necessary to always handle the water.

The fixing step 30 and the ascending path by the roller pair 43 having a plurality of treatment liquid holding functions are the water washing step 40. There is a fixer reservoir 32 at the bottom of each process. A temperature sensor and a heater (not shown) are connected to the fixer reservoir 32, and the heated fixer is injected from the upper part of the descending path by the pump 35. The light is circulated and supplied to the photosensitive material (hereinafter sometimes simply referred to as a photosensitive material) F by the nozzle 38.

By circulating and supplying the fixing solution as the processing solution thus heated, the rollers, the processing solution holding member and the processing solution impregnated into them are heated. As a means, a roller or a holding member having a processing liquid holding function may be directly heated by a heater (not shown) to secondarily heat the processing liquid that comes into contact with the photosensitive material.

The roller pair 43 on the ascending path has a processing liquid holding function, and the washing water is heated by a heater (not shown) or the like, and the upper roller pair 43 has a processing liquid holding function.
And the photosensitive material F, and the fixing solution storage section 3 is provided by spontaneous fall.

The water and the concentrated fixer from the concentrated fixer replenisher tank 71 are commanded to operate the pumps 73 and 164 in accordance with the amount of processed photosensitive material by a replenishment controller (not shown). And is supplied to the water washing step 40, is supplied to the upper roller pair 43, and is washed with water while being mixed with the fixing solution in the lower fixing solution storage section 32 to be diluted. Then, a part of the increased fixing liquid is discharged to the waste liquid storage tank 91. In this way, the fixing solution which is always kept in a normal state is injected from the injection nozzle 38, flows down on the roller pair 33 and the photosensitive material F, and forms a circulation path to be returned to the fixing solution storage section 32.

A part of the processing liquid of (1) is reduced and transferred to the waste liquid tank 91. Along with this, the tanks 71 and 81 of the concentrated replenishing solutions of the respective processing agents are replenished. At that time, water corresponding to the diluted preparation must be supplied. Further, the waste liquid is concentrated and delivered to a recovery company, and the evaporated condensed water generated at that time is stored in a water tank as a water storage tank 161.

Therefore, the waste liquid is transferred from the waste liquid storage tank 91 to the evaporative concentration container 140 by the metering pump 93,

Thus, when the treating agent is solid or the amount of water evaporated from the waste liquid and recovered in the dehumidifier due to evaporation from the treatment process is insufficient with respect to the amount of water used, moisture contained in the outside air is removed. A dehumidifier can be used to collect water to make up for the water shortage.

In the third embodiment, as shown in the schematic view of FIG. 2 in addition to the embodiment of the first or second embodiment, the water storage tank 161 has its liquid level as described above. When the liquid level sensor 163 detects a low level, the solenoid valve 167 is opened, and tap water is directly injected from the supply plug 166 or the supply tank and is controlled so as to be closed when reaching the upper liquid level. It is designed so that there is no hindrance to the replenishment of diluting water or washing water.

As a result, the waste liquid can be concentrated, the handleability of the waste liquid can be improved, the amount of water used can be significantly reduced, and the operation can be performed fully automatically.
