Description

Overflow and drain device for a tank

This design relates to the field of developing chemical tanks, and more specifically, it is possible to reduce the manufacturing cost by not using a drain valve while simultaneously allowing the overflow pipe and the drain pipe to be integrated into one, while having the same function. An apparatus for overflow and drain treatment of a liquid tank, which is relatively easy to maintain.

In order to develop the photographic film, a developer is required. Since the developer is present as a liquid, a tank for holding it is required.

The tank for storing the liquid containing the developing chemical as described above is generally provided with an overflow and drain treatment device for preventing the liquid from overflowing or draining the liquid into the waste liquid container as necessary.

In the conventional liquid tank overflow and drain treatment apparatus, as shown in FIG. 1, the overflow tube 3 and the drain tube 4 provided between the liquid tank 1 and the waste liquid container 2 are provided. And a drain valve 5 installed in the middle of the drain pipe 4 to open and close the flow path of the drain pipe 4, wherein the upper end of the overflow pipe 3 is It is installed through the liquid tank (1) to the height of the upper limit of the liquid, the upper end of the drain pipe (3) is made of a structure that is installed so as to be located on the bottom surface through the liquid tank (1).

The overflow and drain treatment apparatus of the conventional liquid tank by the above-described configuration is used in the waste liquid container 2 through the overflow pipe 3 when the liquid contained in the liquid tank 1 overflows the liquid upper limit. The liquid flows down automatically so that the liquid tank 1 does not overflow, and when the user opens the drain valve 5, the liquid contained in the liquid tank 1 is drained while the drain valve 5 is open. 2) it flows down into the waste container 2 so that the user can adjust the level of the liquid in the liquid tank (1).

However, such a conventional liquid tank overflow and drain processing apparatus requires two pipes and a drain valve of an overflow pipe and a drain pipe, resulting in an increase in manufacturing cost and relatively difficult maintenance. .

The purpose of the present invention is to solve such a conventional problem, and while having the same function, it is possible to integrate the overflow pipe and the drain pipe into one and at the same time reduce the manufacturing cost by not using the drain valve. It is to provide a liquid tank overflow and drain treatment device that can be relatively easy to maintain.

1 is a configuration diagram of an overflow and drain treatment apparatus of a conventional liquid tank.

2 is a block diagram of an overflow and drain treatment apparatus of a liquid tank according to an embodiment of the present invention.

DETAILED DESCRIPTION Hereinafter, the most preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. . Other objects, features, and operational advantages, including the purpose, operation, and effect of this design, will become more apparent from the description of the preferred embodiment.

For reference, the embodiments disclosed herein are only presented by selecting the most preferred embodiment from among the various possible examples to help those skilled in the art to understand, the technical spirit of the present invention is not necessarily limited or limited only by this embodiment In addition, various changes, additions and changes are possible within the scope without departing from the technical spirit of the present invention, as well as other embodiments that are equally clear.

The arrangement of the overflow and drain treatment apparatus of the liquid tank according to one embodiment of the present invention is installed between the liquid tank 1 and the waste liquid container 2, as shown in FIG. Drain pipe (7) is formed while the screw 71 is formed so as to penetrate the liquid tank (1) and located on the bottom surface, and to be coupled to the screw 71 of the drain pipe (7) at the lower end The overflow pipe 6 is formed with a screw 62 and an overflow hole 610 is formed at a position corresponding to the height of the upper limit of the liquid of the liquid tank 1 and the handle 63 is formed at the upper end thereof. It is made to include.

With the above configuration, the operation of the overflow and drain treatment apparatus of the liquid tank according to the embodiment of the present invention is as follows.

Normally, the screw 71 formed on the upper portion of the drain tube 7 and the screw 62 formed on the lower portion of the overflow tube 6 are connected to each other so that the drain tube 7 and the overflow tube ( 6) to be integrated.

Thus, when the drain pipe 7 and the overflow pipe 6 are integrated, the overflow hole of the overflow pipe 6 when the liquid contained in the liquid tank 1 overflows the liquid upper limit line ( The liquid which flows down through 61) flows down into the waste liquid container 2 through the drain pipe 7 connected to the overflow pipe 6, so that the liquid tank 1 does not overflow and serves as an overflow pipe. do.

However, when the user grasps and rotates the handle 63 formed at the upper end of the overflow tube 6, the user forms the screw 71 formed on the upper part of the drain tube 7 and the lower part of the overflow tube 6. When the screw 62 is released and the drain tube 7 and the overflow tube 6 are separated from each other, the liquid contained in the liquid tank 1 is discharged through the drain tube 7. As it flows down to), it serves as a drain pipe.

In this case, even if there is no separate drain valve, the overflow pipe 7 serves as a drain valve so that the drain pipe 7 is operated.

Therefore, the user can use the overflow tube 6 as an overflow tube or drain tube by integrating or separating the overflow tube 6 from the drain tube 7 as necessary.

As discussed in the above embodiment, this design can reduce the manufacturing cost and maintain the maintenance by not using the drain valve while allowing the overflow pipe and the drain pipe to be integrated as one, while having the same function. It has an effect that can be easily done.
