Description

Technical Field

[0001] This utility model belongs to the field of disinfection devices. More specifically, this utility model relates to a concentrated hydrochloric acid disinfection device for testing and quarantining silkworm microparticle disease. Background Technology

[0002] In the inspection and quarantine of silkworm microsporidiosis, concentrated hydrochloric acid is a commonly used disinfectant. Its strong acidity and volatility impose special requirements on the safety of disinfection operations and environmental protection. Currently, conventional disinfection containers are mostly sealed with simple lids, a structure that cannot achieve a sustained seal. Because concentrated hydrochloric acid continuously releases hydrogen chloride gas at room temperature, the tiny gap between a standard sealing cap and the container opening is insufficient to effectively prevent gas escape. Furthermore, over long-term use, the sealing material may age and deform due to hydrochloric acid corrosion, further reducing the reliability of the seal. Leaks of hydrochloric acid gas not only irritate the respiratory tract of operators but also corrode laboratory equipment and pollute the environment.

[0003] To address the aforementioned sealing issues, the industry has attempted to employ water-sealed structures. However, in concentrated hydrochloric acid environments, the water layer within traditional water-sealed tanks continuously absorbs the volatilized hydrogen chloride gas, gradually forming a dilute hydrochloric acid solution. This lowers the pH value of the water-sealing liquid, weakening its sealing effect; furthermore, the generated dilute hydrochloric acid is corrosive to the water-sealed tank and its surrounding structures, potentially accelerating equipment damage. Maintaining a durable and effective seal in a highly volatile and corrosive concentrated hydrochloric acid environment, while simultaneously preventing secondary contamination, has become a pressing technical challenge in this field. Utility Model Content

[0004] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0005] One objective of this invention is to provide a concentrated hydrochloric acid disinfection device for testing and quarantining silkworm microparticle disease. This device can achieve continuous and effective sealing during the concentrated hydrochloric acid disinfection process, preventing the volatilization and leakage of hydrogen chloride gas, while overcoming the problem of sealing failure caused by the absorption of hydrogen chloride gas in traditional water seal structures.

[0006] To achieve these objectives and other advantages of this utility model, a concentrated hydrochloric acid disinfection device for the inspection and quarantine of silkworm microparticle disease is provided, comprising: The disinfection tank has an acid drain port at the bottom, and a first valve is installed at the acid drain port; A first water seal tank is provided at the opening of the disinfection tank. A first rubber gasket is provided on the inner wall of the first water seal tank. The cross-section of the first rubber gasket is triangular to form an inclined contact surface on the inner wall of the tank. The first sealing cover has a first water seal edge on its edge and a second rubber gasket on the inner side of the first water seal edge. When the first sealing cap is placed on the disinfection tank, the second rubber gasket abuts against the contact surface of the first rubber gasket to form the first seal. The free end of the first water seal edge extends into the first water seal tank so that after alkaline liquid is injected into the first water seal tank, the free end of the first water seal edge is submerged below the liquid surface to achieve the second seal.

[0007] Preferably, it also includes an acid-base neutralization tank, which is connected to the acid discharge port.

[0008] Preferably, the bottom of the first water seal tank is provided with a first drain outlet, and a second valve is provided at the first drain outlet, and the acid-base neutralization tank is connected to the first drain outlet.

[0009] Preferably, the acid-base neutralization tank has an open structure with a second drain outlet at the bottom and a third valve at the second drain outlet. The upper end of the acid-base neutralization tank has a liquid inlet that is connected to the acid drain outlet, and the height of the liquid inlet is lower than that of the acid drain outlet.

[0010] Preferably, the acid-base neutralization tank is provided with a second sealing cover.

[0011] Preferably, the acid-base neutralization tank is provided with a second water seal tank at the tank opening, a third drain outlet is provided at the bottom of the second water seal tank, a fourth valve is provided at the third drain outlet, and a second water seal edge is provided on the edge of the second sealing cover, with the free end of the second water seal edge extending below the water surface in the second water seal tank.

[0012] Preferably, it also includes a disinfection basket, the top of which is provided with two handles, and a torsion spring is provided at the hinge of the handles and the disinfection basket so that the two handles can rotate upwards in a figure-eight shape under the tension of the torsion spring.

[0013] Preferably, it also includes: A concentration sensor is installed on the inner wall or bottom of the disinfection tank to monitor the concentration of concentrated hydrochloric acid in the disinfection tank in real time; a display screen is installed on the outer wall of the disinfection tank and is connected to the concentration sensor to display the hydrochloric acid concentration value monitored by the concentration sensor in real time.

[0014] Preferably, it also includes: The fastening assembly includes a fixing block disposed on the outer wall of the disinfection tank and a movable fastening arm disposed on the edge of the first sealing cover. The free end of the movable fastening arm is provided with an eccentric cam quick-locking mechanism. When the first sealing cover is closed, the movable buckle arm can rotate to engage with the fixed block, and the rotation of the eccentric cam quick-lock mechanism presses the first sealing cover onto the disinfection tank to enhance the sealing between the first rubber gasket and the second rubber gasket.

[0015] This invention offers at least the following advantages: It effectively blocks the volatilization of concentrated hydrochloric acid through a double-sealing structure. A rubber gasket forms the first seal between the first sealing cap and the disinfection tank, which, combined with the second liquid seal formed by injecting alkaline liquid into the first water seal tank, constitutes a reliable sealing system. This design not only significantly reduces hydrogen chloride gas leakage, avoiding environmental pollution and equipment corrosion, but also overcomes the problem of traditional water seals gradually failing due to hydrogen chloride absorption. The use of alkaline liquid neutralizes the volatilized acidic gas, maintains the pH value of the water seal liquid, and ensures the durability of the sealing effect. Simultaneously, the device has a simple and reasonable structure, is easy to operate, and improves the safety and reliability of the disinfection process.

[0022] like Figure 1-4 As shown, a concentrated hydrochloric acid disinfection device for testing and quarantining silkworm microsporidiosis includes: The disinfection tank 1 has an acid drain port at its bottom, and a first valve is installed at the acid drain port; The first water seal trough 2 is located at the opening of the disinfection tank 1. The inner wall of the first water seal trough 2 is provided with a first rubber gasket 7. The cross-section of the first rubber gasket 7 is triangular to form an inclined contact surface at the inner wall of the trough. The first sealing cover 3 has a first water seal edge on its edge, and a second rubber gasket 8 is provided on the inner side of the first water seal edge; When the first sealing cap 3 is placed on the disinfection tank 1, the second rubber gasket 8 abuts against the abutting surface of the first rubber gasket 7 to form a first seal. The free end of the first water seal edge extends into the first water seal tank 2 so that after alkaline liquid is injected into the first water seal tank 2, the free end of the first water seal edge is submerged below the liquid surface to achieve a second seal.

[0023] The disinfection tank 1 can be a rectangular or circular container made of acid-resistant materials such as polypropylene or stainless steel, with a capacity selectable from 10 liters to 100 liters, for example, 30 liters. An acid drain port is provided at the bottom of the disinfection tank 1, with a diameter selectable from 10 mm to 50 mm, for example, 20 mm. A first valve is installed at the acid drain port, which can be a ball valve or a butterfly valve, made of polytetrafluoroethylene or stainless steel to resist corrosion from concentrated hydrochloric acid. A first water seal tank 2 is located at the opening of the disinfection tank 1, and can be integrally formed with the disinfection tank 1 or connected by welding. The depth of the first water seal tank 2 can be selectable from 50 mm to 150 mm, for example, 100 mm. A first rubber gasket 7 is installed on the inner wall of the first water seal tank 2. The first rubber gasket 7 has a triangular cross-section, forming an inclined contact surface, with an inclination angle selectable from 30 degrees to 60 degrees, for example, 45 degrees. The material of the first rubber gasket 7 can be fluororubber or ethylene propylene rubber, which can be obtained from chemical suppliers. The first rubber gasket 7 is tightly connected to the inner wall of the first water seal groove 2.

[0024] The first sealing cap 3 has a first water seal edge along its edge, and a second rubber gasket 8 is installed on the inner side of the first water seal edge. The material of the second rubber gasket 8 can be fluororubber or ethylene propylene rubber. The first rubber gasket 7 is fixed to the inner wall of the first water seal groove 2 by adhesive bonding or embedding. For example, an annular groove can be provided on the inner side, and the second rubber gasket 8 is partially bonded in the groove, with part of it exposed in the annular groove, so that the exposed part can abut against the contact surface to seal and prevent concentrated hydrochloric acid from passing through, forming the first seal. The free end of the first water seal edge extends into the first water seal groove 2, and the insertion depth can be selected in the range of 20 mm to 50 mm, for example, 30 mm. The specific operation is as follows: First, press down the first sealing cap 3 against the opening of the disinfection tank 1 so that the contact surfaces of the second rubber gasket 8 and the first rubber gasket 7 are in close contact to form the first seal; then inject an alkaline liquid, such as sodium hydroxide solution, into the first water seal tank 2. The concentration can be selected in the range of 1% to 5%, for example, 2%. After injection, the free end of the first water seal edge is submerged below the liquid surface. The liquid level can be maintained 10 mm to 30 mm above the free end of the first water seal edge, for example, 20 mm, to achieve the second seal. The liquid level is lower than the second rubber gasket 8.

[0025] The device provided by this technical solution can effectively block the volatilization of concentrated hydrochloric acid through a double-sealed structure, reduce hydrogen chloride leakage, lower the risk of environmental pollution, and improve the safety and reliability of the disinfection process.

[0026] In another technical solution, an acid-base neutralization tank 4 is also included, which is connected to the acid discharge port.

[0027] The acid-base neutralization tank 4 can be designed as an open-top tank with a capacity ranging from 30 liters to 150 liters (e.g., 50 liters). The material can be polypropylene or polyethylene. A second drain outlet is located at the bottom of the tank, with a diameter ranging from 15 mm to 40 mm (e.g., 25 mm). A third valve is installed at the drain outlet; the valve type can be a ball valve or a gate valve, and the material can be polytetrafluoroethylene (PTFE). A liquid inlet is located at the top of the tank, with a diameter ranging from 20 mm to 50 mm (e.g., 30 mm). The liquid inlet is connected to the acid drain outlet of the disinfection tank 1 via a connecting pipe. The height difference between the centerline of the liquid inlet and the centerline of the acid drain outlet of the disinfection tank 1 can be ranging from 100 mm to 300 mm (e.g., 150 mm) to ensure that the liquid flows out by gravity.

[0028] During assembly, the second drain outlet is located at the lowest point of the tank bottom, and the third valve is connected to the drain outlet via a flange or thread. The inlet is located on the upper side wall of the tank and is connected to the acid drain outlet of disinfection tank 1 via a PVC or stainless steel pipe. The pipe can be kept at a certain inclination, for example, a 20 mm drop per meter. During operation, when the first valve of the acid drain outlet of disinfection tank 1 is opened, the waste acid flows into the acid-base neutralization tank 4 through the pipe from the inlet. After the neutralization reaction is completed in the tank, the third valve is opened, and the treated liquid is discharged from the second drain outlet. Parameter settings include determining the tank volume based on the amount of waste acid, typically 1.5 to 2 times the capacity of disinfection tank 1. For example, if the disinfection tank is 130 liters, the acid-base neutralization tank 4 would be 50 liters.

[0029] This technical solution, by setting up an acid-base neutralization tank 4 with a specific structure, can effectively collect and treat the waste acid liquid discharged from the disinfection tank 1, utilize the height difference to achieve liquid gravity flow, reduce energy consumption, and facilitate the discharge of liquid after the neutralization reaction.

[0030] In another technical solution, the bottom of the first water seal tank 2 is provided with a first drain outlet, and a second valve is provided at the first drain outlet. The acid-base neutralization tank 4 is connected to the first drain outlet.

[0031] The diameter of the first drain outlet at the bottom of the first water seal tank 2 can be selected within the range of 15 mm to 40 mm, for example, 25 mm. The drain outlet can be a standard pipe thread interface. The second valve can be a ball valve or a butterfly valve, with a nominal diameter selected within the range of 20 mm to 50 mm, for example, 30 mm. The valve body material can be PTFE-lined or stainless steel. The first drain outlet is located at the lowest point of the bottom of the first water seal tank 2 and is connected to the second valve via a flange or thread. The connecting pipe can be made of PVC or stainless steel, with an inner diameter selected within the range of 20 mm to 50 mm, for example, 30 mm. The two ends of the pipe are connected to the outlet of the second valve and the inlet of the acid-base neutralization tank 4, respectively.

[0032] During operation, when it is necessary to drain the liquid in the first water seal tank 2, the second valve is opened, and the liquid flows out through the first drain outlet under the action of gravity and enters the acid-base neutralization tank 4 through the connecting pipe.

[0033] This technical solution, by setting a drain outlet at the bottom of the first water seal tank 2 and connecting it to the acid-base neutralization tank 4, can conveniently discharge and centrally treat the waste liquid in the water seal tank, realize unified treatment of waste liquid, reduce operation steps, and reduce the impact of waste liquid on the environment.

[0034] In another technical solution, the acid-base neutralization tank 4 has an open structure with a second drain outlet at the bottom and a third valve at the second drain outlet. The upper end of the acid-base neutralization tank 4 has a liquid inlet that is connected to the acid discharge outlet, and the height of the liquid inlet is lower than that of the acid discharge outlet.

[0035] A second drain outlet is located at the bottom of the tank, with a diameter selectable between 15 mm and 40 mm (e.g., 25 mm). A third valve is installed at the drain outlet; the valve type can be a ball valve or a gate valve, and the material can be polytetrafluoroethylene (PTFE). A liquid inlet is located at the top of the tank, with a diameter selectable between 20 mm and 50 mm (e.g., 30 mm). The liquid inlet is connected to the acid drain outlet of sterilization tank 1 via a connecting pipe. The height difference between the centerline of the liquid inlet and the centerline of the acid drain outlet of sterilization tank 1 can be selectable between 100 mm and 300 mm (e.g., 150 mm) to ensure that the liquid flows out by gravity.

[0036] During assembly, the second drain outlet is located at the lowest point of the tank bottom, and the third valve is connected to the drain outlet via a flange or thread. The inlet is located on the upper side wall of the tank and is connected to the acid drain outlet of disinfection tank 1 via a PVC or stainless steel pipe. The pipe can be kept at a certain inclination, for example, a 20 mm drop per meter. During operation, when the first valve of the acid drain outlet of disinfection tank 1 is opened, the waste acid flows into the acid-base neutralization tank 4 through the pipe from the inlet. After the neutralization reaction is completed in the tank, the third valve is opened, and the treated liquid is discharged from the second drain outlet. The tank volume is determined according to the amount of waste acid, usually 1.5 to 2 times the capacity of disinfection tank 1. For example, if the disinfection tank is 130 liters, the acid-base neutralization tank 4 is 50 liters.

[0037] This technical solution, by setting up an acid-base neutralization tank 4 with a specific structure, can effectively collect and treat the waste acid liquid discharged from the disinfection tank 1, utilize the height difference to achieve liquid gravity flow, reduce energy consumption, and facilitate the discharge of liquid after the neutralization reaction.

[0038] In another technical solution, the acid-base neutralization box 4 is provided with a second sealing cover 6.

[0039] The thickness of the second sealing cover 6 can be selected from 3 mm to 8 mm, for example, 5 mm. The sealing cover material can be polypropylene or polyethylene, which are corrosion-resistant. The second sealing cover 6 can be connected to the acid-base neutralization tank 4 via hinges. The hinges can be made of stainless steel, and the number can be 2 to 4, for example, 3. A sealing gasket can be placed on the contact surface between the sealing cover and the tank body. The gasket material can be silicone rubber or fluororubber, and the thickness can be selected from 2 mm to 5 mm, for example, 3 mm. During assembly, the hinges are fixed to the edge of the tank body and the edge of the sealing cover, and the sealing gasket is fixed to the contact surface of the sealing cover by adhesive.

[0040] During operation, when acid-base neutralization is required, open the second sealing cap 6 and add the neutralizing agent; after the operation is complete, close the sealing cap, and a sealed interface is formed between the sealing gasket and the chamber. Parameter settings include determining the size of the sealing cap based on the chamber dimensions; typically, the diameter of the sealing cap is 10 to 30 millimeters larger than the diameter of the chamber opening, for example, 20 millimeters larger. During functional testing, a small amount of hydrochloric acid solution can be added to the chamber, and after closing the sealing cap, observe whether any gas escapes. The experimental subject can be actual waste acid solution after use, and the sealing effect can be monitored using a gas detector.

[0041] This technical solution, by setting a second sealing cover 6 on the acid-base neutralization tank 4, can effectively seal the tank during intermittent use, reduce the volatilization of acidic gases, improve the operating environment, and prevent external impurities from entering the neutralization tank.

[0042] In another technical solution, a second water seal tank 5 is provided at the opening of the acid-base neutralization tank 4, a third drain outlet is provided at the bottom of the second water seal tank 5, a fourth valve is provided at the third drain outlet, and a second water seal edge is provided on the edge of the second sealing cover 6, with the free end of the second water seal edge extending below the water surface in the second water seal tank 5.

[0043] The second water seal tank 5 can be located at the edge of the opening of the acid-base neutralization tank 4. The tank depth can be selected from 40 mm to 100 mm, for example, 60 mm, and the tank width can be selected from 30 mm to 80 mm, for example, 50 mm. The second water seal tank 5 can be made of polypropylene or polyethylene, integrally molded with the tank body or welded together. A third drain outlet is provided at the bottom of the tank. The diameter of the drain outlet can be selected from 10 mm to 30 mm, for example, 15 mm. A fourth valve is installed at the drain outlet; the valve type can be a ball valve or a butterfly valve, and the material can be polytetrafluoroethylene (PTFE). A second water seal edge is provided along the edge of the second sealing cover 6. The height of the water seal edge can be selected from 50 mm to 120 mm, for example, 80 mm, and the material is the same as the sealing cover.

[0044] During assembly, the second water seal groove 5 surrounds the tank opening, the third drain outlet is located at the lowest point of the groove, and the fourth valve is fixed to the drain outlet via a threaded connection. The second water seal edge is perpendicularly connected to the edge of the second sealing cover 6, forming an inverted U-shaped structure. During operation, alkaline liquid is first injected into the second water seal groove 5, maintaining the liquid level 10 mm to 30 mm above the free end of the water seal edge, for example, 20 mm. Then, the second sealing cover 6 is placed on top, submerging the second water seal edge below the liquid surface to form a liquid seal. Parameter settings include determining the amount of alkaline liquid injected based on the circumference of the tank opening; for example, approximately 5 liters of liquid are injected when the circumference is 1 meter.

[0045] In some designs, a third rubber gasket can be added to the second water seal trough 5, and a fourth rubber gasket can be set on the second water seal edge corresponding to the second sealing cover 6. When the second sealing cover 6 is closed on the box opening, the third rubber gasket and the fourth rubber gasket abut against each other to form the first seal, and the alkaline liquid in the second water seal trough 5 forms the second liquid seal. This sealing structure is the same as the sealing structure formed by the first rubber gasket 7 and the second rubber gasket 8.

[0046] This technical solution, through the combined use of the second water seal tank 5 and the second water seal edge, can enhance the sealing effect of the acid-base neutralization tank 4, reduce the volatilization of gas during the neutralization process, and facilitate the replacement of the liquid in the tank through the third drain outlet, thus maintaining the stability of the liquid seal effect.

[0047] In another technical solution, a disinfection basket 9 is also included. The top of the disinfection basket 9 is provided with two handles 10. A torsion spring is provided at the hinge of the handles 10 and the disinfection basket 9 so that the two handles 10 can rotate upward under the tension of the torsion spring to form a figure-eight structure.

[0048] The sterilization basket 9 can be rectangular or cylindrical to match the shape of the sterilization tank 1. Its capacity can be selected from 5 liters to 20 liters, for example, 10 liters. The material can be polypropylene or stainless steel. Two handles 10 are symmetrically arranged on both sides of the top of the sterilization basket 9. The length of the handles 10 can be selected from 100 mm to 200 mm, for example, 150 mm, and the diameter of the handles 10 can be selected from 10 mm to 20 mm, for example, 15 mm. The handles 10 are connected to the sterilization basket 9 via hinge shafts. The diameter of the hinge shafts can be selected from 5 mm to 10 mm, for example, 8 mm. Torsion springs can be fitted onto the hinge shafts. The wire diameter of the torsion springs can be selected from 1 mm to 2 mm, for example, 1.5 mm, and the number of coils can be selected from 5 to 10 coils, for example, 8 coils.

[0049] During assembly, the hinge shaft passes through the mounting hole on the side wall of the disinfection basket 9 and the through hole in the base of the handle 10. The two ends of the torsion spring are fixed to the fixing points on the base of the handle 10 and the side wall of the disinfection basket 9, respectively. During operation, when no external force is applied, the tension of the torsion spring causes the two handles 10 to rotate upwards, forming a figure-eight structure with an included angle between 30 and 60 degrees, for example, 45 degrees. When it is necessary to place or remove the disinfection basket 9, the operator can hold the handles 10 to operate it; when the sealing cap is closed, the weight of the sealing cap presses the handles 10 downwards, causing the handles 10 to fit against the edge of the basket opening.

[0050] This technical solution, by setting a handle 10 with a torsion spring on the disinfection basket 9, enables convenient and safe handling of the disinfection basket 9, reducing the risk of operators directly contacting concentrated hydrochloric acid. At the same time, the automatic opening function of the handle 10 improves the ease of operation.

[0051] Another technical solution also includes: A concentration sensor is installed on the inner wall or bottom of the disinfection tank 1 to monitor the concentration of concentrated hydrochloric acid in the disinfection tank 1 in real time. The display screen is located on the outer wall of the disinfection tank 1 and is connected to the concentration sensor for real-time display of the hydrochloric acid concentration value monitored by the concentration sensor.

[0052] The concentration sensor can be an electrochemical or optical hydrochloric acid concentration sensor, which are commercially available off-the-shelf devices. The sensor range can cover hydrochloric acid concentrations from 0% to 40%, with an accuracy of ±0.5%. The sensor probe material can be Hastelloy or PTFE to resist corrosion from concentrated hydrochloric acid. The sensor can be installed on the inner wall or bottom of the disinfection tank 11, with the inner wall installation position ranging from 50 mm to 150 mm above the bottom of the tank, for example, 100 mm. During installation, it is fixed with threads or flanges, and an acid-resistant sealing ring is used to ensure a tight seal. During operation, the concentration sensor continuously monitors the concentration of concentrated hydrochloric acid in the disinfection tank 1 and outputs an analog or digital signal.

[0053] The display screen can be an LCD or LED screen, with a size ranging from 3 to 7 inches, such as 5 inches. The screen housing can be made of ABS engineering plastic with an IP65 protection rating. The display screen can be installed on the outer wall of the disinfection tank 11 at a height that allows for easy observation, such as 100 mm to 200 mm from the top of the tank. During assembly, it is fixed using a bracket or recessed mounting, and waterproof connectors are used at the wiring points. The display screen connects to the concentration sensor via cable or wirelessly, and the connection interface can be RS485 or 4-20mA analog signal. During operation, the display screen receives and processes the signals from the concentration sensor in real time, displaying the current hydrochloric acid concentration value digitally, with an update frequency of once per second.

[0054] This technical solution can monitor the concentration of disinfectant in real time, ensuring the disinfection effect and avoiding waste or safety hazards caused by insufficient or excessive concentration.

[0055] Another technical solution also includes: The fastening assembly includes a fixing block 11 disposed on the outer wall of the disinfection tank 1 and a movable fastening arm 12 disposed on the edge of the first sealing cover 3. The free end of the movable fastening arm 12 is provided with an eccentric cam quick-locking mechanism 13. When the first sealing cover 3 is closed, the movable buckle arm 12 can rotate to engage with the fixed block 11, and the first sealing cover 3 is pressed onto the disinfection tank 1 by the rotation of the eccentric cam quick-lock mechanism 13, so as to enhance the sealing between the first rubber gasket 7 and the second rubber gasket 8.

[0056] The fixing block 11 can be made of polypropylene and its structure can be cuboid or cylindrical. The length of the fixing block 11 can be selected from 50 mm to 100 mm, for example, 70 mm, and the thickness can be selected from 10 mm to 20 mm, for example, 15 mm. The fixing block 11 is fixed to the outer wall of the disinfection tank 11 by welding or bolting, and the installation position is 50 mm to 150 mm below the tank opening, for example, 100 mm. Usually, 2 to 4 blocks are symmetrically arranged. The length of the movable latch arm 12 can be selected from 200 mm to 400 mm, for example, 300 mm, and the cross-section can be rectangular or circular. The movable latch arm 12 is connected to the edge of the first sealing cover 33 through a hinge shaft. The hinge shaft can be made of stainless steel and its diameter can be selected from 8 mm to 12 mm, for example, 10 mm.

[0057] The eccentric cam quick-lock mechanism 13 can be a commercially available standard part, made of corrosion-resistant materials such as alloy steel, stainless steel, or engineering plastics. The eccentricity of the eccentric wheel in the quick-lock mechanism can be selected within the range of 5 mm to 10 mm, for example, 7 mm. This mechanism is connected to the free end of the movable latch arm 12 via a pin, the diameter of which can be selected within the range of 6 mm to 10 mm, for example, 8 mm. During assembly, the fixed block 11 and the movable latch arm 12 are positioned correspondingly to ensure that the movable latch arm 12 can accurately engage with the fixed block 11 when rotating. During operation, when the first sealing cover 33 is closed on the disinfection tank 11, the movable latch arm 12 is rotated to the position of the fixed block 11, and the pin is rotated to make the eccentric wheel of the eccentric cam quick-lock mechanism 13 rotate and abut against the lower surface of the fixed block 11.

[0058] This technical solution can provide a stable and reliable clamping force, enhance the sealing between the first rubber gasket 77 and the second rubber gasket 88, reduce the risk of gas leakage, and improve the convenience of the closing operation.

[0059] The fastening components can be 2-6. For example, if the disinfection tank 1 is rectangular, one or two fastening components can be provided on each side to ensure a tight connection between the first sealing cover 3 and the disinfection tank 1.
