DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid injection order sorting device that can sort liquids in the order of injection.

In order to know the changes in the quality of medical test liquids that are continuously provided for a long time, or the quality of running water, waste water, etc. over time, we can incorporate them and analyze them according to the order of intake and by time zone, etc. There is a need for a liquid sorting device that has a simple structure for sorting liquids.

In order to satisfy the above-mentioned needs, the present invention provides a cylindrical liquid reservoir that is installed upright with an injection port provided on the upper side, and has a plurality of compartments having a series of steps at predetermined intervals in the vertical direction. A reservoir having a predetermined internal capacity is connected to each outlet of the separator, which is provided with an inlet and a plurality of outlets corresponding to the plurality of inlets are provided at the lower side of the cylindrical liquid reservoir. It is an object of the present invention to provide a liquid injection order sorting device which has a simple structure and is capable of sorting liquids according to the order in which they are taken in, such as by time period.

The present invention provides a cylindrical liquid reservoir in which a plurality of dividing intake ports having a series of steps at predetermined intervals in the vertical direction are provided inside a cylindrical liquid reservoir that is installed upright with an injection port provided on the upper side. A storage device having a predetermined internal capacity is connected to each outlet of a separator in which a plurality of outlet ports corresponding to the plurality of intake ports are provided at the lower side of the reservoir. .

Next, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 shows the first part of the liquid injection order sorting device of the present invention.
FIG. 2 is an exploded perspective view of the main parts of the embodiment.

A thick disk-shaped plate 4 with a stepped portion 3 formed on the outer periphery is fitted into the hole 2 on the top surface of the hollow box body 1, which is a base. Multiple cylindrical (six cylindrical in this example) intake ports 5, 6, 7, 8, each having a step α.
9 and 10 are arranged circumferentially at equal intervals and are fitted through the box body 1 in the vertical direction, and on the upper side of the box body 1,
A cylindrical liquid reservoir 11 surrounding the intake ports 5, 6, 7, 8, 9, and 10 is fitted onto the step 3 of the plate 4, and the lid has a liquid receiving port 12 at the upper end opening of the liquid reservoir 11. 13 is inserted. The lid 13 has a bottomed cylinder 14 protruding downward from the center thereof, which forms a hole 12 serving as the liquid receptacle, and a downwardly directed circular tube 15 protruding from the center of the bottom of the cylinder 14. Six small holes 16 penetrating in the vertical direction are formed on the outer periphery of 12.

A tube-shaped outlet 18 is connected to each of the protruding parts 17 of the intake ports 5, 6, 7, 8, 9, and 1 into the hollow box 1, and the outlet ports 18 are connected to the outside through holes in the side of the box 1. Their ends 19 are connected by couplings 20 to respective reservoirs 5A, 6A of predetermined internal capacity.
It is detachably connected to 7A, 8A, 9A, and 10A. In addition, each storage 5A, 6A, 7A, 8A,
From near the mouths of 9A and 10A, inside each tube-shaped discharge port 18, cylindrical intake ports 5, 6, 7, 8, 9,
A thin pipe 21 for air venting that penetrates inside 10
are protruded from the small holes 16 of the lid 13, respectively.

Next, the operation of the above embodiment will be explained.

In the liquid injection order sorting device 200 of this embodiment, when the test liquid is continuously poured into the hole 12 serving as a liquid receiving port, the test liquid travels through the circular tube 15 and drips onto the center portion 41 of the plate 4. . The test liquid dropped onto the plate 4 is first poured into the reservoir 5A from the intake port 5 through the discharge port 19 and is stored therein. When the reservoir 5A becomes full, it overflows from the intake port 5 and begins to fill the liquid reservoir 11. Next, (2) when the liquid level rises by the step α and reaches the upper end of the intake port 6, it is poured from the intake port 6 through its discharge port 19 into the reservoir 6A and stored therein, and the reservoir 6A becomes full. Continuing (3),
As in the case (2), when the liquid level rises by the step α and reaches the upper end of the intake port 7, it is poured from the intake port 7 through its discharge port 19 into the reservoir 7A and stored, until the reservoir 7A is full. Become. Further, in the same manner, (4) the reservoir 8A is filled, then (5) the reservoir 9A is filled, and then (6) the reservoir 10A is filled.

As described above, the test liquid is transferred to the liquid reservoir 11.
Each reservoir 5A, 6A, 7A, 8A, 9A, 1 according to the order of injection except for some residual
It is classified as 0A.

In the above-mentioned division operation, the speed of injection into the liquid receiving port 12 is kept constant, and each reservoir 5A,
If the internal capacities of 6A, 7A, 8A, 9A, and 10A are set to be the same, each storage 5A, 6A, 7A, and 8
In A, 9A, and 10A, injection liquids within the same continuous time period can be divided and stored.

In the above embodiment, the intake port is cylindrical, but in the second embodiment shown in an exploded perspective view in FIG.
Of course, it may be 0, 80, 90, or 100, and in this case, the whole can be made compact, the liquid reservoir can be made smaller, and the amount remaining in the liquid reservoir can be reduced. Further, in the above embodiment, there are six intake ports and six reservoirs, but it goes without saying that the number may be increased or decreased as necessary.

Furthermore, since the entire device is compact, it is convenient to store the entire device in a heat-insulating box or the like when it is used to separate sample liquids that require low-temperature maintenance.

In the liquid injection order sorting device of the present invention, a plurality of sorting intake ports having steps at predetermined intervals in the vertical direction are provided inside a cylindrical liquid reservoir that is installed upright with an injection port provided on the upper side. , a storage device having a predetermined internal capacity is connected to each outlet of a separator in which a plurality of outlets corresponding to the plurality of inlets are provided on the lower side of a cylindrical liquid reservoir; It has a structure of a liquid injection order sorting device characterized by the following features: It has a simple structure, it can sort liquid according to the order of intake, and furthermore, the capacity of each reservoir is the same, and the intake speed is constant. This represents the effect that the injection liquid within the same continuous time width can be classified by time zone.
