Description

Technical Field

[0001] The utility model relates to the technical field of biological and pharmaceutical production equipment, and more specifically, to an automatic feeding solution reactor device. In addition, the utility model also relates to a chemical reaction experimental device comprising the automatic feeding solution reactor device. Background Art

[0002] With the rapid development of medicine, human beings have a variety of means to understand life and treat diseases, and chemical reactions are diverse. However, exothermic chemical reactions and dissolution processes that need to be maintained within a certain temperature range are not easy to control. For example, the feed in cell culture involves a high concentration of strong alkali. For example, the dissolution process of sodium hydroxide will release a large amount of heat. The process of solid solution preparation cannot be directly added to the feed or culture medium, otherwise a large amount of heat will cause the temperature to be too high, affecting the culture and / or key components in the feed, and seriously affecting the nutritional needs of the later cell culture process. Therefore, temperature control is very important; therefore, how to keep the heat of strong alkali dissolution removed as soon as possible during the preparation of the culture medium or feed to ensure the experimental needs is the key to the preparation process. Conventional operations are mostly carried out in cold storage, but the construction cost of cold storage is high. In addition, the time required to prepare the solution is long, and the personnel are prone to fatigue. In addition, the protection requirements for personnel during the strong alkali operation are high. Once the drug directly contacts the skin or splashes on the face during the open sample addition process, it will cause greater damage. When preparing the solution, it often takes a day to complete the preparation of the reagent, which is time-consuming and labor-intensive, seriously affecting the rapid progress of the experiment and increasing the cost of the experiment.

[0003] In summary, how to improve the progress speed of the experiment is an urgent problem to be solved by technical personnel in this field. Utility Model Content

There is a gap between the reaction chamber 2 and the fixed container 3. The distance between the outer wall of the reaction chamber 2 and the inner wall of the fixed container 3 is 5cm-10cm. The fixed container 3 is provided with a liquid inlet 4 and a liquid outlet 5.

[0035] The feeding device is disposed above the reaction chamber 2 and is used to add chemicals into the reaction chamber 2;

[0036] The cooling liquid supply device is connected to the liquid inlet 4 and the liquid outlet 5, and is used to introduce cooling liquid between the reaction chamber 2 and the fixed container 3 and realize the circulation of the cooling liquid.

The coolant can be selected according to the chemicals reacting in the reaction chamber 2, preferably cooling water. The coolant supply device is connected to the liquid inlet 4 and the liquid outlet 5. The coolant supply device can pass the coolant between the reaction chamber 2 and the fixed container 3 through the liquid inlet 4.

The liquid inlet 4 and the liquid outlet 5 can be arranged on the same side or different sides of the fixed container 3. There is no restriction on the specific position. It is sufficient to ensure that the horizontal height of the liquid inlet 4 is lower than the liquid outlet 5 to improve the cooling effect of the coolant.

[0041] On the basis of the above embodiment, a spiral pipeline is arranged between the outer wall of the reaction chamber 2 and the fixed container 3 , and the two ends of the spiral pipeline are respectively connected to the liquid inlet 4 and the liquid outlet 5 , and the spiral pipeline is spirally arranged around the reaction chamber 2 .

The control valve 12 is provided with multiple gears, and the multiple gears are used to regulate the releasable flow in the drainage tube. The drainage tube is used to insert into the through hole 18, and it should be noted that the size of the through hole 18 needs to be larger than the outer circumferential size of the drainage tube to ensure air permeability.

[0053] Optionally, the fixing frame 10 may be circular, but its diameter should be smaller than the maximum diameter of the funnel 11 to prevent the funnel 11 from falling off.

[0055] Specifically, the connection with the power source is achieved through the external power cord 13 and the three-phase plug 14, so that the stirring rotor can be supplied with power. Since heat is released when the solution is prepared, it is safer than the built-in power supply.

[0056] Optionally, a transformer may be connected between the three-phase plug 14 and the socket to ensure voltage stability.

[0057] Based on the above embodiment, the surface of the agitator 1 is provided with a numerical control display screen 15, an adjustment key 16 and a power button 17, and the numerical control display screen 15, the adjustment key 16 and the power button 17 are all connected to the control system signal, and the control system is connected to the stirring rotor signal.
