The present invention relates to a developing device of an automatic developing device for automatically developing an X-ray film, and in particular, to control the flow of a solution made through a circulator and a refilling device, and to conveniently control the water level and drainage. It relates to an X-ray film developing apparatus.

A general X-ray film automatic developing device is an apparatus that automatically performs a series of processes for developing the medical film taken by X-rays with the naked eye, and the configuration thereof is shown in FIGS. 1 and 2. Has been shown. Figure 1 shows a table-type automatic developing, Figure 2 shows a large-scale automatic developing, as shown, the film accommodating portion 21, the detection unit 22, the developing unit 23, the fixing unit 24, the number It consists of the main components of the details (25), the crimping section 26, the drying section 27, the heat exchanger 31, the supplemental pump 32, the drying fan 33 is mounted on the lower portion of the center of the main body 20 The film inserting portion 21 has a structure in which a roller driving device is attached.

As shown in FIG. 3, the X-ray film automatic developing device having the above-described main configuration is first inserted into the detection unit by the detection sensor by inserting the film on which the X-ray imaging is completed. After sensing, it is inserted into the developing unit to perform the developing process. In the developing process, the halogenated silver particles in the exposed emulsion film are converted into silver and become latent images, and most of them are reduced by immersing them in a developing solution to change into black silver particles (developed silver grains). do. When the developing process is completed, a process of melting silver halide which is not reduced by being transferred to the fixing unit is performed. Here, the unexposed silver halide remains as it is in the development process, and when exposed to a bright place as it is, in this state, all of them turn into silver particles and the entire surface becomes black. To prevent this, almost no silver is dissolved, and an aqueous solution of a drug that solubilizes silver halide is used.

After the fixing process is completed, the film is transferred to the water washing unit to remove the fixing solution or silver salt in which the emulsion film remains, and is transferred to the drying unit to remove water from the film and dried with warm air.

In the automatic developing which undergoes such a series of processes, the conventional developing apparatus includes a developing tank 41 in which a chemical solution is embedded to change the latent image of the film into a visible image, and the developing tank 41. A replenishment tank 42 for replenishing the solution, a supply pump 43 for supplying the solution in the replenishment tank 42 to the developing tank 41, and suppressing precipitation of the solution in the developing tank 41. It consists of a circulating pump 44 for continuously circulating the solution and a filter 45 mounted on a line connecting the circulating pump 44 and the developing tank 41 to filter the circulating solution.

The conventional developing apparatus as described above has a problem that the developer is often thrown out of the developing tank by the hydraulic pressure of the circulation pump during the circulation of the solution, which adversely affects the development of the film.

Therefore, the present invention is devised to solve the above problems, the X-ray film to smooth the flow of the solution to prevent the solution of the circulating developer to splash out, and to easily adjust the level in the developer ( Its purpose is to provide an X-ray film developer.

In order to achieve the above object, the present invention, a developing tank in which a developing solution for developing a latent image of the film as a visible image; A circulation pump circulating the solution so that the solution in the developing tank does not precipitate; An X-ray film developing apparatus having a replenishment tank for replenishing a solution to the developing tank and a supply pump for supplying a solution in the replenishment tank to the developing tank, wherein the developing tank has an inner surface of one side of the developing tank. A flow stabilization means mounted on one side thereof and having a bent surface so as to be positioned on an inlet hole of the developing tank, preventing flow of the developing solution by water pressure of the circulation pump and controlling a flow rate; Means for adjusting the water level in the developing tank mounted on the other inner surface of the developing tank; And a drainage tank connected to the outlet hole of the developing tank and storing the developer discharged therefrom.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

The X-ray film developing apparatus of the present invention is implemented to prevent the developing solution from splashing out of the developing tank by the hydraulic pressure of the circulation pump, and as shown in FIG. 4, the developing solution for developing the latent image of the film into a visible image. The inherent developing tank 1 is formed as a storage container having a pentagonal section with an open top, and a developing solution inlet hole 1a and an outlet hole 1b are formed at both sides of the bottom.

And, one side of the developing tank (1) is connected to the supplement tank (2) and the supply pump (3) for supplying a new developer to the inside continuously through the supply line (4), the developing tank ( On one side of the outlet hole 1b of 1), a drain tank 5 for storing the aged developer discharged from the developing tank 1 is provided through the discharge line 6.

In addition, a circulation line 7 is connected to an inlet hole 1a and an outlet hole 1b of the developing tank 1 to provide a developer circulation path, and a circulation pump 8 is mounted on the circulation line 7. Thus, the developer is circulated continuously so that the developer inherent in the developing tank 1 does not precipitate.

On one inner surface of the developing tank 1, fixing plates 9 formed of opposed grids are mounted at predetermined intervals, and the fixing plate 9 has an upright surface 10a having a cross shape and an inflow hole of the developing tank 1. The flow stabilizer plate 10 formed by the bent surface 10b positioned at (1a) is fitted. The flow stabilizer plate 10 is provided with a filter 11 on its bent surface 10b to control the rapid flow rate of the developer flowing into the inlet hole 1a through the circulation pump 8, thereby developing the developer by hydraulic pressure. It prevents splashing out of the developing tank 1 and at the same time performs a function of filtering a small amount of precipitate in the circulating developer.

The filter 11 in this embodiment is formed of a wire mesh or a synthetic resin mesh having a predetermined mesh.

On the other hand, the other side of the developing tank (1) is formed with a guide groove (1c) at a predetermined distance from the side end surface, the guide groove (1c) is provided with a water level control plate 12 to open and close the development tank (1) It is possible to arbitrarily adjust the level of the developer. In addition, the level control plate 12 has a stepped portion 12a formed at an upper end thereof so that the aged developer overflows and maintains the proper level at all times, and the developer overflowing the level control plate flows into the drain tank.

Referring to the working state of the present invention configured as described above are as follows.

As the X-ray photographed film is introduced into the developing tank 1 through the detection unit, the supply pump 3 is operated to continuously introduce new developing solution from the supplement tank 2 into the developing tank 1. Accordingly, the developing solution in the developing tank 1 is discharged through the outlet hole 1b while maintaining a constant water level, and is also developed into the inlet hole 1a through the circulation line 7 in accordance with the operation of the circulation pump 8. It flows in. At this time, the old developer circulating in the developing tank 1 rises due to the dropping pressure of the new developer supplied from the replenishment tank 2, and flows over the stepped portion 12a of the water level control plate 12, thereby draining the tank ( 5) to be collected.

In the process of introducing the developer circulating into the inlet hole 1a of the developing tank 1, the solution flows into the developing tank 1 via the filter 11 of the flow stabilizer plate 10 located in the inlet hole 1a. Therefore, the rapid flow rate by the circulation pump 8 is reduced to flow into the developing tank 1, and when the developer passes through the filter 11, foreign matters such as precipitates after development are filtered out. Therefore, the developer 11 can always maintain a clean developer solution, thereby maintaining the clarity of development, and purging the developer by removing the foreign matter trapped in the filter 11 by removing the flow stabilizer plate 10 every predetermined period and then reattaching it. Will be able to simplify.

On the other hand, in the state where the development of the film is completed, the water level control plate 12 is separated from the guide groove 1c of the developing tank 1, and the developer tank 1 is simply discharged by discharging all of the developing solution into the drain tank 5. You will be able to clean.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

As described above, according to the present invention, by simply adopting the flow stabilization plate and the water level tank plate in the developing tank, the flow rate is controlled by lowering the water pressure according to the operation of the circulation pump to make the flow of the developer constant, and also provided in the flow stabilization plate. It is possible to prevent contamination of the modern liquid by easily filtering foreign substances such as sediment generated after developing through the filter. In addition, by discharging the old developer through the water level control plate to the outside always maintains the proper water level and has the effect of simplifying the cleaning operation by facilitating the discharge of the developer when cleaning the developing tank.
