Description

Technical Field

[0001] This utility model relates to the field of medical and health technology, and more specifically, it relates to a Brucella inactivation device. Background Technology

[0002] In the fields of medical and health care and scientific research, the safe handling of Brucella has always been an important and challenging task. Traditional Brucella inactivation methods usually employ high temperature and high pressure sterilization technology. Although this method is effective, it has some significant limitations in actual operation. The primary problem is how to safely and effectively release the high pressure inside the sterilization equipment after the sterilization process. Existing inactivation devices often lack precise pressure relief control mechanisms, which not only increases operational risks but may also affect the inactivation effect. Sudden pressure release may lead to sample contamination or safety hazards, while excessively slow pressure relief may prolong the entire processing and reduce work efficiency.

[0003] Furthermore, the handling of high-risk pathogens such as Brucella in biosafety laboratories and medical institutions is subject to extremely stringent requirements. The inactivation process not only needs to ensure that the pathogens are completely inactivated, but also needs to ensure the safety and controllability of the entire process. However, the design of existing inactivation devices in the depressurization stage is often too simple and cannot meet the needs of precise control. In this case, operators may need to manually intervene in the depressurization process, which not only increases the complexity of the operation, but also potentially increases the biosafety risks. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a Brucella inactivation device to solve the technical problems mentioned in the background art, which often lack a precise pressure relief control mechanism. This not only increases the operational risk, but may also affect the inactivation effect. Sudden pressure release may cause sample contamination or safety hazards, while excessively slow pressure relief may prolong the entire processing and reduce work efficiency.

[0006] (II) Technical Solution

The inactivation tank is mounted on the support base, the sealing cap is located at one end of the inactivation tank, the placement rack is installed inside the inactivation tank, the water storage tank is located inside the placement rack, and the heater is installed on the outer wall of the inactivation tank. A pressure relief mechanism is provided at the top of the inactivation tank. The pressure relief mechanism includes a pressure relief sleeve, a spiral plate, a mating sleeve, a connecting sleeve, a sealing plate, a control sleeve, a connecting rod, a central rod, and a sliding groove. The pressure relief sleeve is mounted on the inactivation tank, the spiral plate is mounted on the inner wall of the pressure relief sleeve, the mating sleeve is mounted on the top of the spiral plate, the connecting sleeve is threaded into the mating sleeve, the sealing plate is mounted at the bottom of the connecting sleeve, the control sleeve rotates at the top of the pressure relief sleeve, multiple sets of connecting rods are provided and mounted on the inner wall of the control sleeve, the central rod is mounted between the multiple sets of connecting rods, and the sliding groove is located in the connecting sleeve and slidably connected to the central rod.

[0008] The present invention is further configured such that an installation block is installed on the outer wall of the inactivation tank, and a hinge arm is installed on the sealing cover. The hinge arm is rotatably connected to the installation block. This design improves the ease of operation and sealing effect of the sealing cover. The installation block provides a stable connection point for the hinge arm, while the hinge arm allows the sealing cover to be easily opened and closed, while ensuring a tight fit when closed, effectively preventing high-pressure steam leakage.

[0009] The present invention is further configured such that a sealing groove is provided on the bottom surface of the pressure relief sleeve and a sealing strip is provided on the bottom surface of the sealing plate. This configuration greatly improves the sealing performance of the pressure relief mechanism. The precise fit between the sealing groove and the sealing strip ensures complete sealing in the non-pressure relief state, preventing accidental leakage of high-pressure steam, and also improving the controllability of the pressure relief process.

[0010] The present invention is further configured such that the top surface of the mating sleeve is provided with a sliding rod, the inner wall of the pressure relief sleeve is provided with an inner ring, and multiple sets of sliding rods are provided and slidably connected with the inner ring. This design enhances the stability and accuracy of the pressure relief mechanism. The sliding connection between multiple sets of sliding rods and the inner ring ensures the stability of the mating sleeve during movement, prevents skewing or jamming, and thus improves the accuracy and reliability of pressure relief adjustment.

[0011] The present invention is further configured such that both the central rod and the sliding groove are polygonal and slide in fit. The polygonal design increases the contact area and transmission stability, prevents rotation during sliding, ensures precise correspondence between the central rod and the sliding groove, and improves the operating accuracy and controllability of the entire pressure relief mechanism.

[0012] The present invention is further configured such that the outer wall of the pressure relief sleeve is provided with a positioning mechanism, the positioning mechanism including a positioning groove, a positioning block, a locking sleeve and a push spring. Multiple sets of positioning grooves are distributed on the outer wall of the pressure relief sleeve, multiple sets of positioning blocks slide on the control sleeve, the locking sleeve slides on the outer wall of the pressure relief sleeve, and multiple sets of push springs are installed on the bottom surface of the locking sleeve and connected to the pressure relief sleeve. This complex positioning mechanism design realizes automatic locking and precise positioning of the pressure relief setting. Multiple sets of positioning grooves and positioning blocks provide multi-level adjustment options, and the push springs ensure the automaticity and reliability of locking, greatly improving the operational safety and convenience of the device.

[0013] The present invention is further configured such that the outer wall of the pressure relief sleeve is provided with a limiting strip, and multiple sets of the limiting strip are provided and slidably connected with the locking sleeve. The design of the limiting strip further enhances the stability and accuracy of the locking sleeve movement. Multiple sets of limiting strips ensure that the locking sleeve maintains linear movement during sliding, preventing skew or shaking, thereby improving the reliability and accuracy of the positioning mechanism.

[0014] The present invention is further configured such that a reset spring is installed on the inner side of each of the multiple sets of positioning blocks. The reset spring is provided in multiple sets and is connected to the outer wall of the control sleeve. The design of the reset spring ensures that the positioning block can automatically return to the initial position after unlocking. The multiple sets of reset springs increase the reliability of the system and also improve the convenience and efficiency of the adjustment operation, enabling the operator to make repeated adjustments quickly and accurately.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a Brucella inactivation device, which has the following beneficial effects:

[0017] 1. The sterilization mechanism achieves efficient inactivation of Brucella bacteria through the ingenious combination of inactivation tank, sealing cap, placement rack, water storage tank and heater. This design not only generates a high temperature and high pressure environment for sterilization, but also ensures the stable placement of samples during the processing. The connection design between the hinged arm and the mounting block improves the sealing performance and ease of operation of the sealing cap, effectively solving the problems of poor sealing or cumbersome operation of traditional sterilization equipment. The water storage tank allows water vapor to be evenly distributed, improving the consistency of sterilization effect.

[0018] 2. The design of the pressure relief mechanism greatly improves the safety and controllability of the device. Through the ingenious combination of the pressure relief sleeve, spiral plate, mating sleeve, connecting sleeve, sealing plate, control sleeve, connecting rod, central rod, and slide groove, precise control and release of pressure inside the inactivation tank are achieved. The operator can rotate the control sleeve to drive the entire mechanism to operate, and ultimately control the position of the sealing plate, thereby adjusting the opening degree of the pressure relief channel. The design of the polygonal central rod and slide groove increases the accuracy and stability of adjustment. The cooperation between the sealing groove and the sealing strip ensures complete sealing in the non-pressure relief state. This design not only allows for flexible adjustment of the pressure relief speed as needed, but also effectively prevents potential safety hazards caused by sudden pressure relief.

[0019] 3. The introduction of the positioning mechanism solves the problem of the pressure relief setting being easily changed accidentally, greatly improving the reliability and ease of use of the device. The combination of the positioning groove, positioning block, locking sleeve, and push spring forms an automatic locking system. When the ideal pressure relief setting is reached, the locking sleeve automatically slides down under the action of the push spring, causing the positioning block to embed into the positioning groove, thereby locking the setting. The limit strip ensures the smoothness of the locking process, and the design of the reset spring allows the positioning block to automatically return to the initial position after unlocking, facilitating the next operation. This design not only ensures the stability of the pressure relief setting during sterilization, but also greatly improves the safety and efficiency of operation. Operators can easily switch between different pressure relief settings to adapt to different sterilization needs, without worrying about the setting being changed accidentally during use, thus ensuring the safety and reliability of the entire inactivation process.

[0029] Please see Figures 1-5 A Brucella inactivation device includes a support base 1, on which a sterilization mechanism is mounted. The sterilization mechanism includes an inactivation tank 2, a sealing cap 3, a placement rack 4, a water storage tank 5, and a heater 6. The inactivation tank 2 is mounted on the support base 1, the sealing cap 3 is located at one end of the inactivation tank 2, the placement rack 4 is installed inside the inactivation tank 2, the water storage tank 5 is located inside the placement rack 4, the heater 6 is installed on the outer wall of the inactivation tank 2, and a pressure relief mechanism is provided at the top of the inactivation tank 2. The pressure relief mechanism includes a pressure relief sleeve 7, a spiral plate 8, a mating sleeve 9, a connecting sleeve 10, and a sealing plate. 11. Control sleeve 12, connecting rod 13, center rod 14 and slide groove 15. Pressure relief sleeve 7 is installed on inactivation tank 2. Spiral plate 8 is installed on the inner wall of pressure relief sleeve 7. Fitting sleeve 9 is installed on the top of spiral plate 8. Connecting sleeve 10 is threadedly connected to fitting sleeve 9. Sealing plate 11 is installed at the bottom of connecting sleeve 10. Control sleeve 12 rotates on the top of pressure relief sleeve 7. Multiple sets of connecting rods 13 are installed on the inner wall of control sleeve 12. Center rod 14 is installed between multiple sets of connecting rods 13. Slide groove 15 is set in connecting sleeve 10 and slidably connected to center rod 14.

[0030] An installation block 16 is installed on the outer wall of the inactivation tank 2, and a hinge arm 17 is installed on the sealing cover 3. The hinge arm 17 is rotatably connected to the installation block 16. This design enables flexible opening and closing of the sealing cover 3 and a stable seal. The rotatable connection between the hinge arm 17 and the installation block 16 allows the sealing cover 3 to be easily opened and closed, while providing sufficient pressure in the closed state to ensure the complete sealing of the inactivation tank 2, effectively preventing high-pressure vapor leakage and improving operational convenience.

[0031] The bottom surface of the pressure relief sleeve 7 is provided with a sealing groove 18, and the bottom surface of the sealing plate 11 is provided with a sealing strip 19. This configuration creates an efficient sealing system. When the sealing plate 11 is in the closed position, the sealing strip 19 is precisely embedded in the sealing groove 18 to form a tight sealing interface, which effectively prevents high-pressure steam leakage. At the same time, when pressure relief is required, the slight movement of the sealing plate 11 can break the seal and achieve precise pressure release.

[0032] The top surface of the fitting sleeve 9 is provided with a sliding rod 20, and the inner wall of the pressure relief sleeve 7 is provided with an inner ring 21. Multiple sets of sliding rods 20 are provided and are slidably connected to the inner ring 21. This design ensures the stable movement of the fitting sleeve 9 during the pressure relief process. The sliding connection between multiple sets of sliding rods 20 and the inner ring 21 provides multi-point support and guidance, preventing the fitting sleeve 9 from tilting or getting stuck during movement, thereby ensuring the smooth operation and precise control of the pressure relief mechanism.

[0033] Both the center rod 14 and the slide groove 15 are polygonal and slide in fit. This polygonal design increases the contact area and transmission stability, prevents the center rod 14 from rotating in the slide groove 15, ensures precise correspondence and linear motion between the two, improves the operating accuracy and controllability of the entire pressure relief mechanism, and makes the pressure release process more precise and reliable.

[0034] In this embodiment, firstly, the sample to be inactivated is placed on the placement rack 4, an appropriate amount of water is injected into the water storage tank 5, and the sealing cap 3 is closed. The sealing cap 3 is connected to the mounting block 16 via the hinge arm 17 to ensure a tight seal. The heater 6 is then activated to heat the outer wall of the inactivation tank 2, causing the temperature inside the tank to rise. Water generates steam at high temperature, which fills the inactivation tank 2, sterilizing the sample under high temperature and pressure to effectively inactivate Brucella bacteria. The rotation control sleeve 12 drives the central rod 14 to rotate through multiple sets of connecting rods 13. The polygonal central rod 14 drives the connecting sleeve 10 to rotate. The rotating connecting sleeve 10 engages with the mating sleeve 9 through a threaded connection, causing the mating sleeve 9 to move downwards and compress the spiral plate 8, facilitating the adjustment of the preset force of the spiral plate 8. When the pressure inside the inactivation tank 2 is too high, the pressure pushes the sealing plate 11 to move the mating sleeve 9 upwards through the sliding sleeve. The mating sleeve 9 pulls the spiral plate 8 to overcome the preset force of the spiral plate 8. When the sealing plate 11 moves upwards, the sealing strip 19 leaves the sealing groove 18, opening the pressure relief channel and allowing the pressure inside the inactivation tank 2 to gradually release.

[0035] Please see Figure 5 As one implementation of the positioning mechanism: the outer wall of the pressure relief sleeve 7 is provided with a positioning mechanism, which includes a positioning groove 22, a positioning block 23, a locking sleeve 24 and a push spring 25. The positioning groove 22 is provided with multiple sets distributed on the outer wall of the pressure relief sleeve 7, the positioning block 23 is provided with multiple sets sliding on the control sleeve 12, the locking sleeve 24 slides on the outer wall of the pressure relief sleeve 7, and the push spring 25 is provided with multiple sets installed on the bottom surface of the locking sleeve 24 and connected to the pressure relief sleeve 7.

[0036] The outer wall of the pressure relief sleeve 7 is provided with limiting strips 26. Multiple sets of limiting strips 26 are provided and are slidably connected to the locking sleeve 24. This design uses multiple sets of limiting strips 26 to precisely guide and restrict the movement of the locking sleeve 24, ensuring that the locking sleeve 24 slides linearly on the outer wall of the pressure relief sleeve 7, preventing the locking sleeve 24 from shifting or rotating, thereby improving the stability and reliability of the positioning mechanism, and making the locking and unlocking operations of the pressure relief setting more precise and smooth.

[0037] Multiple sets of positioning blocks 23 are equipped with return springs 27 on their inner sides. There are multiple sets of return springs 27 and they are connected to the outer wall of the control sleeve 12. This design ensures that the positioning blocks 23 can automatically return to the initial position after unlocking through the elastic force of the return springs 27. The multiple sets increase the reliability and response speed of the system, enabling the operator to make repeated adjustments quickly and accurately. It also prevents the positioning blocks 23 from getting stuck in the non-working position, thus improving the operating efficiency and reliability of the entire positioning mechanism.

[0038] More specifically, when adjusted to the appropriate pressure relief position, the locking sleeve 24 slides downward under the action of the push spring 25, so that the positioning block 23 is embedded in the positioning groove 22 on the outer wall of the pressure relief sleeve 7. Multiple sets of limit bars 26 ensure the smooth movement of the locking sleeve 24. This locking mechanism prevents the control sleeve 12 from rotating accidentally during use and maintains the stability of the set pressure relief state. When readjustment is required, the locking sleeve 24 can be pushed up against the force of the push spring 25, so that the positioning block 23 is disengaged from the positioning groove 22. The reset spring 27 on the inner side of the positioning block 23 ensures that the positioning block 23 can automatically return to the initial position after unlocking, which is convenient for the next locking operation.

[0039] In summary, the overall equipment is used or operated as follows: First, place the sample to be inactivated on the placement rack 4, fill the water storage tank 5 with an appropriate amount of water, and close the sealing cover 3. The sealing cover 3 is connected to the mounting block 16 via the hinge arm 17 to ensure a tight seal. Then, start the heater 6 to heat the outer wall of the inactivation tank 2, causing the temperature inside the tank to rise. Water generates steam at high temperature, which fills the inactivation tank 2, sterilizing the sample under high temperature and pressure to effectively inactivate Brucella bacteria. The rotation control sleeve 12 drives the central rod 14 to rotate through multiple sets of connecting rods 13. The polygonal central rod 14 drives the connecting sleeve 10 to rotate. The rotating connecting sleeve 10 engages with the mating sleeve 9 through a threaded connection, causing the mating sleeve 9 to move downwards and compress the spiral plate 8, facilitating the adjustment of the preset force of the spiral plate 8. When the pressure inside the inactivation tank 2 is too high, the pressure pushes the sealing plate 11 to move the mating sleeve 9 upwards through the sliding sleeve. The mating sleeve 9 pulls the spiral plate 8 to overcome the preset force of the spiral plate 8. When the sealing plate 11 moves upwards, the sealing strip 19 leaves the sealing groove 18, opening the pressure relief channel and allowing the pressure inside the inactivation tank 2 to gradually release.

[0040] After being adjusted to the appropriate pressure relief position, the locking sleeve 24 slides downward under the action of the push spring 25, so that the positioning block 23 is embedded in the positioning groove 22 on the outer wall of the pressure relief sleeve 7. Multiple sets of limit bars 26 ensure the smooth movement of the locking sleeve 24. This locking mechanism prevents the control sleeve 12 from rotating accidentally during use and maintains the stability of the set pressure relief state. When readjustment is required, the locking sleeve 24 can be pushed up against the force of the push spring 25, so that the positioning block 23 is disengaged from the positioning groove 22. The reset spring 27 on the inner side of the positioning block 23 ensures that the positioning block 23 can automatically return to the initial position after unlocking, which is convenient for the next locking operation.

For all the fixed connections mentioned above, welding is preferred.
