[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thermostatic bath apparatus used for conducting chemical reactions, stirring, mixing, etc. under a required constant temperature.

[0002]

[Prior Art]

 A device shown in FIG. 2 has been conventionally known as this type of device and will be described with reference to FIG. That is, in the figure, 51 is a constant temperature tank having a required volume, 52 is a stirring blade mounted in the constant temperature tank 51 through a required mounting metal fitting, and 53 is a motor for rotating the stirring blade 52. -54, 55 are a heating body and a cooling body such as a heater installed in the constant temperature bath 51, and the heating body 54 and the cooling body 55 are interlocked with each other via an automatic temperature controller (not shown). It is supposed to work. In addition, A indicates a bath liquid filled with water or the like in the constant temperature bath 51.

In the conventional example configured as described above, the stirring blade 52 is rotated at a constant speed by the operation of the motor 53, while the heating body 54 and the cooling body 55 are operated in conjunction with each other, and The bath solution A is kept at a predetermined temperature. Then, a substance contained in a required container is put into a constant temperature bath 51 by a conventional method to carry out a chemical reaction, stirring and mixing.

[0004]

[Problems to be solved by the device]

 The above-mentioned conventional example has a compact structure and can be used very easily. On the other hand, the heating body 54 and the cooling body 55 are provided in the constant temperature bath 51 to directly heat and cool the bath liquid A to adjust the temperature. Therefore, it is very difficult to maintain a constant temperature at all times because the temperature difference during temperature control tends to become severe. In addition, since the stirring blade 52 is directly provided in the constant temperature bath 51 together with the heating member 54 and the cooling member 55, not only the effective utilization space in the constant temperature bath 51 is significantly reduced, but also the reaction container and the like are brought into contact with each other. It had a defect that it was easily damaged.

This invention not only solves the conventional problems all at once, greatly increases the effective use space in the constant temperature bath, and can always keep the bath liquid at a constant temperature. An object of the present invention is to provide a thermostatic oven device that does not damage the reaction vessel.

[0006]

[Means for Solving the Problems]

 That is, in this invention, the adjusting bath 2 is connected to the constant temperature bath 1 via the liquid feeding / refluxing pipes 3 and 11 so that the bath liquid can freely circulate, and the required heating body 8 and cooling body 9 are provided in the adjusting bath 2. A substantially cap-shaped jammer plate 4 having a required diameter having a through hole 5 is attached to a tip portion of the liquid supply pipe 3 which is internally provided and is located in the adjustment tank 2, and in the jammer plate 4. It has a configuration in which a required stirring blade 6 is provided to correspond to the liquid delivery pipe 3.

[0007]

[Action]

 The bath liquid A in the constant temperature bath 1 is sequentially fed into the adjusting bath 2 through the liquid feeding pipe 3, and the heating blade 8 and the cooling body 9 are operated in conjunction with each other while stirring in a swirling manner with the stirring blade 6. Therefore, after the temperature is adjusted to a predetermined temperature, it is returned to the constant temperature bath 1 again via the reflux pipe 11 and circulated, whereby the bath liquid A in the constant temperature bath 1 is always kept at a constant temperature.

【Example】

 An embodiment of the present invention shown in the drawings will be described below. Reference numeral 1 denotes a thermostatic chamber having a required volume whose outer side is surrounded by a heat insulating material, 2 is an adjusting tank which is disposed under the thermostatic chamber 1 and which is surrounded by a heat insulating material, and 3 is a bottom of the thermostatic chamber 1. In the connected liquid feed pipe, the free end portion of the liquid feed pipe 3 is arranged horizontally in the adjustment tank 2 substantially at the center. 4 is a substantially cap-shaped baffle plate attached to the tip of the liquid feed pipe 3, 5 is a required number of through holes formed at an equal pitch on the outer peripheral wall of the baffle plate 4, and 6 is a liquid feed pipe 3 The stirring blades 7 are provided in the baffle plate 4 so as to correspond to the tips thereof, and 7 is a motor for rotating the stirring blades 6. Reference numeral 8 denotes a heating element such as a heater arranged in a spiral shape in the adjusting tank 2 so as to surround the free end portion of the liquid feeding pipe 3, and 9 denotes a spiral shape so as to surround the outer circumference of the heating element 8. A cooling body 10 provided with water or cold water as a refrigerant is a temperature sensor installed in the upper part of the adjusting tank 2, and the cooling body 9 and the heating body 8 are automatically detected by the temperature sensor 10. A temperature controller (not shown) operates in conjunction with each other. Reference numeral 11 is a reflux pipe that connects the upper portion of the adjustment layer 2 and the upper end portion of the constant temperature bath 1 via the lid body 12 in a communicating manner.

In the embodiment configured as described above, the bath liquid A in the constant temperature bath 1 is circulated through the adjustment layer 2 and kept constant at a predetermined temperature. That is, the bath liquid A in the constant temperature bath 1 is sequentially fed into the baffle plate 4 of the adjustment bath 2 through the liquid feeding pipe 3, and the heating blade 8 and the cooling body are stirred while being swirled by the rotation operation of the stirring blade 6. The bodies 9 are operated in conjunction with each other to adjust the temperature to a predetermined temperature. The bath liquid A adjusted to a predetermined temperature is returned to the constant temperature bath 1 again via the reflux pipe 11. Similarly, the bath liquid A in the constant temperature bath 1 is circulated through the adjustment bath 2 and kept at a constant temperature at a predetermined temperature in the same manner as described above, and is used for the required purpose as in the conventional example.

[0010]

[Effect of the device]

 Since the present invention is configured as described above, the bath liquid A in the constant temperature bath 1 is sequentially fed into the adjustment bath 2 via the liquid delivery pipe 3, and is agitated by the agitating blades 6 in a swirling manner while heating the heating element. 8 and the cooling body 9 are operated in conjunction with each other to adjust the temperature to a predetermined temperature, and then the bath liquid A in the thermostat 1 is returned to the thermostat 1 via the reflux pipe 11 and circulated. Not only can the temperature be maintained constantly and reliably at a constant temperature, but the stirring blade 6 and heating element 8 are not directly installed inside the constant temperature tank 1 as in the conventional example. The effective utilization space of the constant temperature bath 1 can be greatly increased, and there is no risk of damage to the reaction vessel during use.
