Description

Technical Field

[0001] This utility model belongs to the field of polypeptide production and processing technology, and relates to a low-temperature centrifugation device for ether substances. Background Technology

[0002] In the production and processing of peptides, initially, peptides are usually mixed with some ethers and other impurities. Centrifugation equipment is generally used to remove impurities. However, ethers usually have a low flash point. During centrifugation, the friction between ethers and other substances will cause the material to heat up, making the ethers in the centrifuge equipment at risk of ignition, thus leading to safety accidents. Utility Model Content

[0003] The purpose of this invention is to provide a low-temperature centrifugation device for ether-containing materials, which effectively reduces the risk of ignition when centrifuging materials containing ethers.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A low-temperature centrifugation device for ethers includes a main body with a tank, a centrifuge disc coaxially arranged inside the tank, a gas pipe, a cooling assembly, a gas pump, and a gas tank. The centrifuge disc and the lower part of the tank form a sealed space. The bottom surface of the centrifuge disc is evenly provided with a plurality of air holes. The upper part of the tank is provided with a first exhaust port and a second exhaust port. One end of the gas pipe is connected to the first exhaust port, and the other end of the gas pipe is connected to the input end of the gas pump. The output end of the gas pump is connected to the sealed space. The cooling assembly is configured to cool the gas pipe. The gas tank stores inert gas and is branched onto the gas pipe. A valve is provided on the gas pipe.

[0006] Furthermore, the sealed space is evenly divided into six parts around the central axis of the centrifugal disc by a partition, and the three parts that are in a centrally symmetrical position are connected to the first switching valve.

[0007] Furthermore, the first switching valve is an electrically controlled valve.

[0008] Furthermore, it also includes a controller and a temperature sensor, the temperature sensor being adapted to monitor the temperature inside the tank, the temperature sensor being connected to the input terminal of the controller, and the output terminal of the controller being connected to the air pump.

[0009] Furthermore, it also includes a control panel connected to the controller.

[0010] Furthermore, it also includes a suction pump, the input end of which is connected to the tank body, and the output end of which is connected to the outside.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This novel low-temperature centrifuge device includes a main body with a tank, as well as a gas pipe, a cooling component, a gas pump, and a gas tank. Before centrifugation, the second exhaust port is opened, and inert gas from the gas tank is introduced into the tank, forcing the air inside the tank out through the second exhaust port. The second exhaust port is then closed, and the material to be centrifuged is placed into the tank of the main body. During centrifugation, the gas pump continuously enters the sealed space and is introduced through the air vent. Inert gas overflows from the side of the material and the ground, which not only reduces the adsorption of different material components but also allows the low-temperature inert gas to carry away heat, preventing the risk of ignition due to excessively high temperatures in ether-containing substances. Simultaneously, the inert gas flowing through the material is discharged through the first exhaust port and cooled by the cooling component before being recycled back into the tank. This effectively reduces the internal temperature of the tank, minimizing the risk of ignition when centrifuging ether-containing materials. Furthermore, the amount of inert gas can be replenished through the gas tank when necessary. Attached Figure Description

[0025] As described in the background section, in the initial production and processing of peptides, peptides are usually mixed with some ethers and other impurities. Centrifugation equipment is generally used to remove impurities. However, ethers usually have a low flash point.

[0026] Based on this, the inventors created a low-temperature centrifugation device for ether substances, as described in this application, to solve the aforementioned technical problems.

[0027] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0028] Example

[0029] Please see Figure 1 , Figure 2A low-temperature centrifuge device for ether-based substances includes a main body with a tank 10, inside which a centrifuge disc 11 is coaxially arranged. It should be noted that the centrifuge disc 11 refers to a rotating component that primarily centrifuges the material; for example, the edge of the centrifuge disc 11 can be fitted into the side wall of the tank 10. The low-temperature centrifuge device also includes a gas pipe 20, a cooling assembly 30, a gas pump 40, and a gas tank 50. The centrifuge disc 11 and the lower inner part of the tank 10 form a sealed space 12. Here, inert gas is introduced into the sealed space, allowing it to exit through the gas vent 111, thus flowing from the bottom surface towards the material, dispersing the material while simultaneously cooling it. The bottom surface of the centrifugal disc 11 is evenly provided with a plurality of air holes 111. The upper part of the tank 10 is provided with a first exhaust port 13 and a second exhaust port 14. One end of the air pipe 20 is connected to the first exhaust port 13, and the other end of the air pipe 20 is connected to the input end of the air pump 40. The output end of the air pump 40 is connected to the sealed space 12. The cooling component 30 is configured to cool the air pipe 20. The gas tank 50 stores inert gas and branches off to the air pipe 20. A valve 21 is provided on the air pipe 20. Here, the first exhaust port 13 is mainly used for the circulation of inert gas, and the second exhaust port 14 is mainly used to discharge air during initial use, so that the tank 10 is filled with inert gas. For example, the cooling component 30 can be a water-cooling device, which achieves cooling by wrapping the water-cooling device around the air pipe 20, or it can be a refrigerator, etc. This utility model is not limited to these.

[0030] The low-temperature centrifuge device of this invention includes a main body with a tank 10, a gas pipe 20, a cooling component 30, a gas pump 40, and a gas tank 50. Before centrifugation, the second exhaust port 14 is opened, and inert gas from the gas tank 50 is introduced into the tank 10, squeezing out the air inside the tank 10 from the second exhaust port 14. The second exhaust port 14 is then closed, and the material to be centrifuged is placed into the tank 10 of the main body. During centrifugation, the gas pump 40 continuously enters the sealed space 12 and is introduced through the air hole 111. Inert gas overflows from the side of the material and the ground, which not only reduces the adsorption of different material components, but also allows the low-temperature inert gas to carry away heat, preventing the risk of ignition due to excessively high temperatures in ether-containing substances. At the same time, the inert gas flowing through the material is discharged through the first exhaust port 13 and cooled by the cooling component 30 before being recycled back into the tank 10. This effectively reduces the temperature inside the tank 10, reducing the risk of ignition when centrifuging ether-containing materials. Furthermore, the amount of inert gas can be replenished through the gas tank 50 when the amount is insufficient.

[0031] Furthermore, the sealed space 12 is evenly divided into six parts around the central axis of the centrifugal disc 11 by a partition. The first group of three centrally symmetrical parts is connected to a first switching valve 112, and the second group of three centrally symmetrical parts is connected to a second switching valve. In this way, the first switching valve 112 can control the opening and closing of half of the sealed space 12, thereby allowing half or all of the vents 111 to be opened as needed. Furthermore, the first switching valve 112 can be an electrically controlled valve.

[0032] Furthermore, the system also includes a controller and a temperature sensor. The temperature sensor is adapted to monitor the temperature inside the tank 10. The temperature sensor is connected to the input terminal of the controller, and the output terminal of the controller is connected to the air pump 40. With this configuration, the temperature inside the tank 10 is monitored by the temperature sensor and fed back to the controller, thereby allowing the temperature inside the tank 10 to be controlled by adjusting the power of the air pump 40. Furthermore, the system also includes a control panel connected to the controller.

[0033] Furthermore, it also includes a suction pump, the input end of which is connected to the tank 10, and the output end of which is connected to the outside. This configuration allows the suction pump to quickly expel the air from inside the tank 10 and fill it with inert gas.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
