Description

Technical Field

[0001] This utility model relates to the field of cooling technology, and in particular to a polypeptide lysis circulating cooling device. Background Technology

[0002] During peptide cleavage, heat is generated. The circulating cooling device mainly consists of a cooling unit, a circulation unit, a temperature control unit, and a cleavage reaction vessel. The heat generated by the cleavage reaction is absorbed by the cooling medium (such as cold water or coolant) in the cooling pipes of the cooling unit. The circulation pump drives the cooling medium to circulate in the pipes to achieve continuous heat transfer, and the temperature control unit monitors the reaction temperature in real time.

[0003] Temperature can be precisely regulated by controlling the flow rate of the cooling medium or the operation of the refrigeration equipment, so that the pyrolysis reaction can proceed under suitable temperature conditions, ensuring the stability of the reaction and the quality of the products.

[0004] External environmental factors (such as ambient temperature) can interfere with the accuracy of temperature control. In the hot summer, the high ambient temperature can affect the heat dissipation effect of the cooling device, leading to deviations in temperature control. Utility Model Content

[0030] Example 1

[0031] This embodiment proposes a polypeptide lysis circulating cooling device, such as... Figure 1 As shown, the reactor includes a reactor 1, a solvent pipe 2 is fixedly installed on the top of the reactor 1, a circulating cooling pipe 3 is connected to the side of the reactor 1, a circulating pump 4 is fixedly installed on the outer wall of the circulating cooling pipe 3 and on the top of the fixed frame 51, and a jacket is provided inside the reactor 1, with the two ends of the circulating cooling pipe 3 connected to the upper and lower ends of the jacket respectively.

[0032] The cooling medium is pumped by the circulating pump 4, thereby circulating the cooling medium in the circulating cooling pipe 3 and the jacket to cool the internal temperature of the reactor 1.

[0033] like Figure 2 As shown, a heat exchange mechanism 5 is provided on the side of the reactor 1. The heat exchange mechanism 5 includes a fixed frame 51. A heat dissipation fin 52 is fixedly installed at the center of the fixed frame 51. A fan 53 is rotatably connected to the back of the fixed frame 51. The fan 53 rotates to accelerate the airflow at the heat dissipation fin 52, thereby reducing the temperature of the cooling medium.

[0034] like Figure 3 and Figure 4 As shown, a bimetallic coil spring 54 is fixedly installed on the side of the fixed frame 51. The end of the bimetallic coil spring 54 is bent and there is a gap between it and the fixed frame 51. A knob 58 electrically connected to the fan 53 is rotatably connected to the top of the fixed frame 51. A transmission intermediate component is provided between the bimetallic coil spring 54 and the knob 58. The transmission intermediate component includes a square frame 56 and a toothed plate 57. The bottom of the toothed plate 57 is slidably connected to the fixed frame 51. Multiple teeth are provided on the outer arc surface of the knob 58. The multiple teeth are distributed in a ring at equal angles along the outer arc surface of the knob 58. The knob 58 is connected to the toothed plate 57 through the teeth. The other side of the toothed plate 57 is fixedly connected to the square frame 56. The end of the bimetallic coil spring 54 extends to the center of the square frame 56.

[0035] The bimetallic coiled spring 54 contracts under the influence of ambient temperature, causing the bent portion at its end to shift. This movement of the spring 54 drives the frame 56, which in turn rotates the knob 58 via the toothed plate 57, thus changing the rotational speed of the fan 53. In high ambient temperatures, the bimetallic coiled spring 54 expands, causing its bent end to rotate counter-clockwise. This moves the toothed plate 57 to the left and rotates the knob 58 clockwise, increasing the fan 53's speed. In low ambient temperatures, the opposite occurs. The knob 58 provides stepless adjustment of the fan 53's speed, and its rotational resistance is low to reduce friction.

[0036] The end of the bimetallic coil spring 54 has a U-shaped structure, and a roller 55 is rotatably connected inside the opening of the bimetallic coil spring 54. The roller 55 slides up and down along the frame 56. The roller 55 and the frame 56 cooperate to prevent the bimetallic coil spring 54 from getting stuck during rotation.

[0037] In this embodiment, when the ambient temperature is high, the cooling effect of the heat dissipation fins 52 on the cooling medium is reduced. If the temperature of the cooling medium is high, the internal temperature of the reactor 1 will be uncontrollable. At this time, by increasing the speed of the fan 53, the airflow speed at the heat dissipation fins 52 is increased, so as to accelerate the heat exchange efficiency between the air and the cooling medium and avoid the ambient temperature from affecting the heat dissipation effect of the cooling device.

[0038] Example 2

[0039] Based on Example 1, this example proposes a polypeptide lysis circulating cooling device, such as... Figure 5 As shown, a preheating mechanism 6 extending to the outer wall of the solvent pipe 2 is provided on the front side of the fixed frame 51. The preheating mechanism 6 includes a heat-concentrating cylinder 61. The end of the heat-concentrating cylinder 61 is fixedly connected to the fixed frame 51. A water tank 64 is fixedly installed on the outer wall of the solvent pipe 2. The water tank 64 is filled with heat-exchange water. A hot air pipe 62 for heating water is fixedly installed at the other end of the heat-concentrating cylinder 61.

[0040] Solvent pipe 2 passes through the axis of heat exchange tube 63. Solvent pipe 2 absorbs heat from the water inside water tank 64. The hot air from the heat dissipation fins 52 is blown into heat collection cylinder 61 by fan 53. Heat collection cylinder 61 heats the water inside water tank 64. Finally, the water in water tank 64 is used to preheat the solvent added to solvent pipe 2.

[0041] A heat exchange tube 63 is fixedly installed at the end of the hot air pipe 62. The heat exchange tube 63 is located inside the water tank 64 and has a spiral structure. The other end of the heat exchange tube 63 extends out from inside the water tank 64. The spiral heat exchange tube 63 extends the residence time of the hot air inside the water tank 64.

[0042] In this embodiment, the hot air at the heat dissipation fins 52 is blown into the heat collection cylinder 61 by the fan 53. The heat collection cylinder 61 transfers the hot air to the water tank 64 to heat the water inside the water tank 64. Finally, the water in the water tank 64 is used to preheat the solvent added at the solvent pipe 2.

[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
