Description

Technical Field

[0001] The utility model relates to the technical field of sterilizing pots, in particular to a biological product sterilizing device. Background Art

[0002] Biological products refer to medicines prepared from biological materials such as microorganisms, cells, and various animal and human tissues and fluids obtained by ordinary or genetic engineering, cell engineering, protein engineering, fermentation engineering and other biotechnologies, and used for the prevention, treatment and diagnosis of human diseases. These medicines often need to be sterilized. There are many sterilization methods, and for biological products, the most reliable one is high-pressure steam sterilization. In the existing technology, high-pressure steam sterilizers are generally used for this operation.

[0003] The principle of a high-pressure steam cooker is similar to that of a pressure cooker, which boils water in a closed container and uses steam to sterilize the items to be sterilized under high pressure and high temperature. The biological products after sterilization have a high temperature and need to be cooled. The natural cooling process takes more than ten minutes, and the water cooling speed is too fast and is not suitable for biological products. Therefore, sterile air cooling is used most of the time. However, during the air cooling process, due to the flow of air, some holes are opened on the device. The existence of these holes can easily cause external bacteria to re-enter the biological products. In view of this, in-depth research was conducted on the above-mentioned issues, which led to this case. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: See Figure 1-4 A biological product sterilization device comprises a cooking barrel 7, a cover 5 is arranged at the top of the cooking barrel 7, and a three-way solenoid valve 2 is arranged on one side of the top of the cover 5, an air inlet pipe 1 is installed at the top of the three-way solenoid valve 2, and an exhaust pipe 3 is installed on one side of the three-way solenoid valve 2, an air supply pipe 4 is installed at the bottom end of the three-way solenoid valve 2, and the bottom end of the air supply pipe 4 is connected with the inside of the cover 5, a fixed cylinder 17 is installed on the other side of the top of the cover 5, and the bottom end of the fixed cylinder 17 is connected with the inside of the cover 5, an exhaust pipe 21 is installed on one side of the fixed cylinder 17, and a threaded block 15 is arranged inside the fixed cylinder 17, a plurality of spring telescopic rods 16 are installed at the bottom end of the threaded block 15, and a piston 20 is installed at the bottom end of the plurality of spring telescopic rods 16, a groove 18 is provided at the bottom end of the piston 20, and an exhaust groove 19 is provided on one side of the groove 18;

[0021] The exhaust groove 19 has the same diameter as the inside of the exhaust pipe 21;

[0022] A placing rack 8 is installed at the bottom of the cooking barrel 7, a placing cage 10 is arranged above the placing rack 8, and a heating pipe 9 is arranged below the placing rack 8;

[0023] Specifically, Figure 1 and Figure 4As shown, when using the device, the biological product to be sterilized is placed in the placement cage 10, water is added to the inside of the cooking barrel 7 and the liquid level is below the placement rack 8, and then the water is heated by the heating tube 9. At the same time, the cover 5 and the cooking barrel 7 form a closed space for sterilization. When the air pressure inside the cooking barrel 7 is too large, it will impact the piston 20, so that the piston 20 overcomes the spring telescopic rod 16 and moves. When the exhaust groove 19 is aligned with the exhaust pipe 21, part of the air pressure can leave through the groove 18, the exhaust groove 19 and the exhaust pipe 21 in turn, avoiding the device The internal pressure is too high. When sterilization is completed, the position of piston 20 can be adjusted to reduce the internal air pressure. Subsequently, sterile cold air can be introduced from the air inlet pipe 1 to be discharged from the exhaust pipe 3. After the airflow passes for a period of time, the three-way solenoid valve 2 is adjusted to guide the airflow to the air supply pipe 4 to enter the device to prevent impurities adhered to the inner walls of the air inlet pipe 1 and the exhaust pipe 3 from entering the device. After the cold air flows into the device, it entrains heat and finally leaves from the exhaust pipe 21. During this process, after some cold air is introduced, the piston 20 can be adjusted to keep the exhaust pipe 21 unobstructed.

[0024] The inner wall of the top of the fixed cylinder 17 is installed with a threaded rod 14 through a rotating shaft, and the top of the threaded rod 14 extends to the top of the fixed cylinder 17 and is installed with a knob, the bottom of the threaded rod 14 extends to the inside of the fixed cylinder 17, and the threaded rod 14 penetrates the inside of the threaded block 15 and forms a threaded fit with the threaded block 15;

[0025] A guide groove is provided on the inner wall of the fixed cylinder 17 above the exhaust pipe 21, a guide block is installed on the outer wall of the threaded block 15, and the threaded block 15 forms a sliding connection with the fixed cylinder 17 through the cooperation between the guide block and the guide groove;

[0026] Specifically, Figure 4 As shown, by rotating the threaded rod 14, the threaded block 15 can be directed to move under the guidance of the guide block and the guide groove, thereby changing the position of the piston 20. When the exhaust groove 19 is completely aligned with the exhaust pipe 21, this place is fully open. On the contrary, when the piston 20 is pressed on the bottom end of the fixed cylinder 17 and the spring telescopic rod 16 is in a compressed state, this place is in a fully closed state. If the spring telescopic rod 16 can be extended and the exhaust groove 19 is below the exhaust pipe 21, a one-way valve is formed here. The above three usage states can be adjusted as needed.

[0027] A plurality of second fixing blocks 12 are installed on the outer wall of the cover 5, and a corresponding number of first fixing blocks 11 are installed on the outer wall of the cooking barrel 7. A rotating rod 6 is provided on the inner wall of the first fixing block 11, and the top end of the rotating rod 6 extends to the top of the second fixing block 12 and is rotatably installed with a limiting plate 13. The second fixing block 12 is U-shaped, and the width of the inside of the second fixing block 12 is less than the length of the limiting plate 13.

[0028] The inner wall of the first fixing block 11 is provided with an internal thread, and the outer wall of the rotating rod 6 is provided with an external thread matching therewith;

[0029] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the lid 5 is placed above the cooking barrel 7, and the limiting plate 13 is passed through the gap in the middle of the second fixed block 12. The limiting plate 13 is then rotated a quarter of a turn, and the rotation of the limiting plate 13 is limited by one hand, and the other hand rotates the rotating rod 6. As the rotating rod 6 moves downward inside the first fixed block 11, it drives the limiting plate 13 until it presses the second fixed block 12, so that the lid 5 can be quickly fixed on the cooking barrel 7.
