Definitions

• the present invention relates to a fluid circuit in a photosensitive material processing apparatus and other processing apparatuses.
• the temperature is adjusted while transferring and circulating the processing liquid to the processing tank.
• fluid circuits that perform only circulation for temperature control except when processing photosensitive materials are often used.
• an electromagnetic valve is provided in the circulation system, and the temperature is circulated by switching the solenoid valve except during processing.
• switching to the processing liquid transfer circulation to the processing top is possible.
• Etc. cannot be used as a cartridge tank (liquid storage tank)
• the structure of the present invention that achieves this object is based on the processing in the storage tank.
• the liquid is sent to the heat exchanger by the first -circulation bomb and its temperature is adjusted.
• Processing liquid transfer circulation that supplies and returns the remaining liquid in this processing tank to the storage tank
• the feature is that the minute and the minute are constituted by the same pipeline.
• FIG. 1 shows an embodiment of a fluid circuit of a processing apparatus according to the present invention.
• FIG. 2 shows the temperature control circulation during non-treatment.
• Fig. 3 illustrates the operation and transfer of processing solution during processing.
• FIG. 1 A first figure.
• FIG. 1 shows an embodiment of a fluid circuit of a processing apparatus according to the present invention.
• FIG. 2 is an operation explanatory view showing temperature control circulation during non-processing
• FIG. 3 is an operation explanatory view showing processing liquid transfer circulation during processing.
• reference numeral 1 denotes a treatment tank, below which a cartridge type storage tank 2 is disposed, and a lower part of the treatment tank 1 is provided by a drainage pipe 3.
• Numeral 0 4 communicating with the liquid storage tank 2 is a first circulation bong.
• the processing liquid 6 is sent to the heat exchanger 7 by the outgoing pipe 5, and the liquid is stored by the return pipe 8 by the return pipe 8. O 9 to be returned to tank 2
• the second circulation pump is the same as the first circulation pump 4]).
• the discharge capacity is large (for example, more than double).
• 10 is a filter
• 11 is a blowout nozzle
• the blowout nozzle 11 the filter 10
• the liquid tank 2 is connected by a forward pipe 12.
• the temperature control circulation circuit that regulates the temperature of the processing liquid 6 in the storage tank 2 is composed of a first circulation pump 4, an outgoing line 5, and a heat exchanger.
• a processing liquid transfer circuit that supplies the processing liquid to the processing tank and returns the remaining liquid to the storage tank 2.
• ⁇ GVPI Consists of a second circulation bomb 9, a filter 10, a blowing nozzle 11, an outgoing pipe 12, and a drain pipe 3 (corresponding to the outgoing pipe). Is done.
• the treatment liquid 6 in the liquid storage tank 2 is sent to the heat exchanger 7 by the first circulation bomb 4 and heated there. After the temperature is adjusted, it is guided to the return line 8 and returns to the liquid storage tank 2 again. In this case, the second circulation bomb 9 should be working.
• the material to be treated is fed into the treatment tank 1, this is detected by a sensor shown in FIG. 2 and the second circulation pump 9 is operated.
• the discharge capacity of the second circulation bomb 9 is equal to the discharge capacity of the first circulation bomb '4! 3)
• the processing liquid 6 sent out from the heat exchanger 7 and the processing liquid in the storage tank 2 were removed.
• Processing liquid 6 injected from 1 is sometimes stored at the bottom of processing tank 1]? Guided by drainage pipe 3 and returned to storage tank 2 again o
• the filter 9 are arranged on the upstream side of the heat exchanger 7 and the filter 10 1 respectively, but the reverse is also possible. Also, the filter
