It consists of a drying part 107. The developing section 104, the fixing section 105, and the water washing section 106 constitute the tanks 104a, 105a, and 106a so as to store the developer, the fixing solution, and the flushing water, respectively. In addition, the film passes through the spaces of the detection unit 103, the developing unit 104, the fixing unit 105, the water washing unit 106, and the drying unit 107 through the feed rollers 108 arranged in a plurality. The feed rollers 108 are arranged in a zigzag manner to maximize the contact between the developer, the fixer, and the wash water with the film as the film passes.

Therefore, when the X-ray film is input through the detection unit 103, the X-ray film is introduced into the water tank 104a of the developing unit 104 along the feed roller 108 and developed by contact with the developer. That is, the developer in contact with the surface of the film forms an image by reducing the silver substance exposed to the film to turn into a metal. The film passing through the developing unit 104 is continuously introduced into the water tank 105a of the fixing unit 105 and fixed by contact with the fixing liquid. In addition, the X-ray film is introduced into the water tank 106a of the water washing unit 106, washed with water to wash the developer and the fixing solution on the surface, and then introduced into the drying unit 107 and dried to complete the film development. .

By the way, in the X-ray film developing machine 101 as described above, the developing waste liquid and the fixed waste liquid can be extracted from the resources such as silver, and separately collected and consigned to the wastewater treatment company, but a small amount of chemicals, gelatin and scales In the case of mixed wash water, the amount reaches 3-6ℓ per minute, and averages about 1 ton per day, which makes it difficult to purify the waste water and there is a problem in that the cost is excessive.

Accordingly, the developer washing water is discharged to the sewer. As compared with the developing solution and the fixing solution, the washing water must be used in a large amount to improve the quality. There is a problem that the amount to be discharged is increased to increase the environmental pollution, as well as waste of water.

Therefore, the present invention has been made in order to solve the above problems, the main object of the present invention is to wash a large amount of washing water by filtering and recycling the washing water flowing from the developer after washing the X-ray film. The present invention provides an automatic developing flushing treatment device that can reduce the cost burden and minimize the environmental pollution and water waste caused by simply throwing the flushing water into the sewer.

In addition, another object of the present invention is to provide an automatic developing water treatment apparatus to minimize the installation space by reducing the overall structure, as well as to reduce the manufacturing cost.
