[Problems with the prior art of the present invention]

In a culture system for microorganisms, etc., a temperature controller 2 is generally installed in a shaking tank device 1 as shown in FIG.
Then, the driving mechanism 3 is installed, and the shaking table 5 is swingably mounted in the constant temperature water bath 4. A culture bottle 7 filled with a culture solution 6 is set on a shaking table, a certain amount of water is poured into the tank, a constant temperature water 8 is stored in the tank by a temperature controller, and the culture is carried out by the shaking action of the shaking table. Measures have been taken to cultivate microorganisms, etc. under a suitable constant temperature. However, in conventional shaking tank devices, the constant temperature water that is shaken in the tank by the left and right shaking action of the shaking table 5 in the direction of the arrow is It often collides with the inner wall of the tank and is pushed upwards, causing droplets to be scattered inside and outside the tank. To solve this problem, (a) make the culture tank deeper and install a shaking table at the bottom; (b) Lower the constant temperature water level in the culture tank. Technical measures such as the following can be considered, but in the case of (a), there is the disadvantage that the culture bottle loses the advantage of being placed at the top of the tank so that it can be easily observed from outside the tank, and in the case of (b), it is difficult to remove the culture bottle due to a drop in the constant temperature water level. This method has the disadvantage that the culture bottle is exposed to the outside air more frequently, which hinders temperature control and culture efficiency. In addition, the drawbacks of conventional devices are the need to maintain a stable culture temperature and to avoid fluctuations in the temperature inside the constant-temperature water tank in order to increase culture efficiency. Permanent culture can be achieved, but if the culture continues for a long time, the constant temperature water in the tank becomes contaminated with bacteria, leading to the deterioration of the observation function and the deterioration of the culture environment. desired.

[Problems to be solved by the present invention] The present invention was made with the aim of solving the above-mentioned difficulties technically and structurally.The first problem is to solve the splash phenomenon caused by constant-temperature water colliding with the inner wall. In other words, the problem can be solved without changing the depth of the tank, which degrades external observation. Second, eliminate contamination of constant temperature water in the tank. Third, when purifying constant-temperature water, minimize temperature fluctuations due to changes in constant-temperature water. Fourth, the new structure is a practical structure that is easy to handle and simple and labor-saving.

The present invention has been proposed as a new culture tank device that solves the above problems.

[Structure and embodiment of the present invention]

The configuration of the present invention is based on the configuration described in the above-mentioned utility model registration claims.

Preferred embodiments of the present invention will be illustrated and described below. FIG. 1 is an overall sectional view of a culture tank showing an embodiment of the present invention, and wave-dissipating plates 10, 10 each having an inverted L-shaped cross section as shown in FIG. When installed, the upper plate 10a is aligned with the upper end of the tank, and the lower plate 10b is allowed to hang down to the appropriate depth of the tank. 11 is an air vent hole provided in the upper part of the hanging plate 10b. In addition to FIGS. 1 and 2, the wave canceling mechanism is shown in FIG. 4, in which the mounting plate 12 and bottom plate 13, which are in close contact with the inner wall of the tank, are bent and integrally formed, as shown in FIGS. 3 and 4. It is also possible to use a wave canceling mechanism of the case body K. Reference numeral 14 denotes an air discharge hole drilled in the inner wall 1a of the tank 1, or in the inner wall 1a and the mounting plate 12 of the wave holding mechanism, and connected to the air pump installed in the tank 1 with a pipe 15 to discharge air a into the tank. do. 16 is a hanging plate 10 of the wave canceling mechanism
A gap 17 is created between the upper and lower walls of the tank by means of a guide plate installed approximately midway between the inner wall 1a and the mounting plate 12.
will be established. A short baffle plate 18 stands in contact with the bottom surface 1b of the tank, and is provided at a constant interval below the lower end of the hanging plate 10b in the direction in which the lower end extends, forming a window 19. The window 19 is an inlet and an inlet for constant temperature water that swings from side to side. Reference numeral 20 denotes a filter installed between the guide plate 16 and the baffle plate 18. The filter 20 is installed flush with the lower end of the guide plate, and the purified constant temperature water filtered by the filter passes through the lower gap 17 and along the inner wall surface and the guide plate. and rise. At this time, air bubbles discharged from the inner wall surface or the lower discharge hole 14 of the mounting plate energize the rising flow force of the constant temperature water. The constant-temperature water purification mechanism installed at the bottom of the tank described above may be installed on both the left and right walls of the tank, but test results show that even if it is installed only on one side of the inner wall as shown in the example drawings, the tank will not work. This shows the purification effect of internally constant temperature water.

As mentioned above, this proposal consists of a wave canceling mechanism attached to the top of the tank and a purification mechanism installed at the bottom of the tank.As mentioned above, the wave canceling mechanism, guide plate, baffle plate, and It is advantageous for handling and operation if the purification mechanism consisting of a filter is constructed in an integrated case K in which each frame is assembled as shown in FIG. 4, and can be installed and removed at will.

The above-mentioned structure is made of a transparent synthetic resin member or the like so that it can be viewed from the outside, and the design is changed as appropriate depending on the purpose and scale of the culture tank apparatus.

[Operation of the present invention]

The structure of the present invention is as exemplified in the above-mentioned embodiments, but to describe its function, the constant temperature water that swings from side to side due to the shaking action of the shaking table in the culture tank is moved between the wave canceling plate 10 and the baffle plate on the wall surface. A part of the water flows through the window 19 opened between 18 and rises along the guide plate, but a part flows downward and is filtered by the filter 20 between the guide plate and the baffle plate, and flows into the inner wall or the mounting plate and the guide plate. It rises along the gap, merges with the other rising constant temperature water, collides with the upper plate 10a of the wave-dissipating plate, turns downward, and flows down along the hanging plate 10b. At this time, the air compressed on the upper surface of the wave-dissipating plate and the air discharged from the air discharge hole are bubbled and discharged to the outside of the tank through the air vent hole 11 provided in the hanging plate. Therefore, the air vent holes are adjusted so as to reduce the pressure on the wave-dissipating plate, reduce the force of the rising waves, reverse the flow, and not disturb the oscillating rhythm of the constant-temperature water caused by shaking. Further, when the pressurized air discharged from the air discharge hole rises as bubbles, it enhances the rising force of the constant temperature water, and acts to increase the force of the constant temperature water passing through the filter.

[Effects of this invention]

The present invention is a structure consisting of the above-mentioned wave canceling mechanism and purifying mechanism, which solves the problems of conventional devices and has new effects and advantages. In other words, even though the tank structure is the same as the conventional one, the phenomenon of splashing when constant temperature water collides with the inner wall due to shaking is eliminated, and the structure does not reduce the advantage of the transparent observation function of the culture bottle from outside the tank. The air vent holes in the eraser board also ensured a stable effect when adjusting the shaking of constant-temperature water. Furthermore, by purifying the thermostatic water in the tank, the culture environment of the apparatus is improved, the problem of contamination of the thermostatic water is eliminated, and the observation effect of the culture bottle is also improved. In addition, the installation of a purification mechanism has greatly reduced the need for constant temperature water conversion, which is useful for long-term culture tests, and temperature changes and adjustments due to exchange have been further improved compared to the past.

Incidentally, since the novel mechanism of the present invention is used as the case body of each frame assembled integrally as shown in FIG. 4, it has the advantage of being easy to handle and providing a labor-saving device.

As described above, the novel structure according to the present invention can be provided as a culture tank device having functionality, efficiency, stability, and durability.
