Description
Technical Field
[0001] The utility model relates to the technical field of constant temperature reaction, in particular to an adjustable constant temperature reaction device. Background Art
[0002] A constant temperature water bath is a commonly used heating device in laboratories. It mainly provides a stable experimental environment through constant temperature and stirring to meet the experimental requirements in fields such as chemistry, biology, and medicine. The working principle of a constant temperature water bath is to heat water or oil to a set temperature by a heating device and keep it constant. When the water temperature is lower than the set temperature, the heater starts to work to increase the water temperature; when the water temperature reaches the set temperature, the constant temperature control system adjusts the heating power to keep the water temperature fluctuating around the set value, thereby achieving the constant temperature effect.
[0003] Constant temperature water baths are widely used in experimental research in fields such as chemistry, biology, and medicine. For example, they are used to control the reaction temperature in chemical experiments; to maintain a stable temperature for cell, bacterial, or tissue cultures in biological experiments; to study drug solubility, stability, dissolution, etc. in drug research; and to control the temperature during food processing in the food processing field.
[0004] Currently, some pharmaceutical chemical reactions often need to be carried out under a constant temperature state, and generally a constant temperature water bath is used to provide a constant temperature environment. However, in some reactions that require observing the reaction process, the constant temperature water bath cannot provide observation and adjustment.
[0005] Thus, it can be seen that in actual work, the existing constant temperature reaction equipment has the following two problems:

[0035] The working principle of the present utility model:
[0036] The temperature sensor 363 is used to monitor the internal temperature change of the constant temperature reaction chamber 3 in real time, facilitating temperature control. During temperature control, it can be controlled by stopping the continuous delivery of high-temperature gas, or by discharging the internal high-temperature gas to achieve the effect of rapid ventilation and cooling, and adjusted according to the use. The temperature value of the high-temperature gas can be manually preset within a threshold range in advance, and being within the threshold range means meeting the requirements of this reaction.

[0039] The first viewing window 33 facilitates manual observation of the inside of the constant temperature reaction chamber 3, and the second viewing window 43 facilitates manual observation of the operating states of the heating wire 42 and the two-way fan 44.
[0040] One end of the top of the two second support rods 22 is fixedly connected to the bottom of the experimental table 1. By installing two first support rods 21, second support rods 22, and reinforcement connecting rods 23 between the experimental table 1 and the support base 2, a reinforcement and support effect is achieved during the overall installation, facilitating subsequent manual observation of the real-time operation data of the reaction equipment.

Reactions can be carried out synchronously inside the internal reaction cylinder 37 and the reaction box 369. According to the requirements of the reaction drug raw materials, the internal reaction cylinder 37 or the reaction box 369 can be selected for the placement of the reaction treatment. Workers can observe the inside through the first viewing window 33. The temperature sensor 363 monitors the temperature changes inside the constant temperature reaction box 3 in real time. During actual use, the length of the heat transfer pipeline 364 can be adjusted as required. That is, one end of the heat transfer pipeline 364 can be placed on the top of the internal reaction cylinder 37 to cooperate better for heating treatment, so as to realize the synchronous reaction treatment inside the internal reaction cylinder 37 and the reaction box 369, and solve the technical problem of shortening the reaction cycle. By setting the recovery plate 5 and the heat collection bin 34 to cooperate with the recovery and discharge of the internal high-temperature gas, it not only protects the internal equipment but also recycles resources, solving the technical problem of increased cost consumption. At the same time, the reaction feeding pipeline 35 can also be externally connected to a cold air conveying pipeline to transport cold air into the reaction box 369 for low-temperature constant temperature treatment, and the temperature can be controlled at minus 10 degrees.
