Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure sterilization, in particular to an autoclave, in particular to a large-volume autoclave. Background Art

[0002] High temperature sterilization refers to killing microorganisms with heat energy. The principle is that high temperature denatures the protein in the protoplasm and inactivates the enzyme, causing the microorganism to die. High temperature sterilization mainly includes high pressure steam sterilization, dry heat sterilization and burning sterilization. The device usually used for high temperature sterilization is a sterilizing pot.

[0003] Most existing autoclaves are manually closed by the lid on the pot body, and then the two are connected by bolts. During the user's use, at least six bolts need to be locked to open and close the lid, which is complicated to operate and has a poor user experience. Therefore, some people have proposed the use of autoclaves with automatic lid opening. Although this type of autoclave can open the lid automatically, the operator still needs to use additional tools to lift the tray or basket in the pot to take and place the sterilized items, which is neither convenient nor safe to operate. Especially for large-volume autoclaves, there are many items placed on the tray or in the basket, and it is also difficult to manually lift and take and place in the high-temperature pot. Summary of the invention

[0004] The utility model aims to provide a sterilizing pot to solve the problems existing in the prior art.

[0013] Furthermore, the number of the connecting rods is 2 to 4 and they are arranged symmetrically. The connecting rods are provided with multiple sections of external threads, and the external threads support the stainless steel tray by connecting washers and nuts.

[0014] Furthermore, the outer diameter of the stainless steel tray is 5 to 20 mm smaller than the inner diameter of the stainless steel liner, and the length of the connecting rod is 5 to 15 mm smaller than the depth of the stainless steel liner.

[0015] In some embodiments, the stainless steel tray is further provided with a detachable porous casing, which is a detachable structure in half and connected by magnetic blocks on both sides.

[0016] In some embodiments, a plurality of hooks are provided on the outer periphery of the rod body of the connecting rod, and items that are difficult to place stably can be hung thereon.

[0017] Furthermore, a control panel is provided below the front of the stainless steel pot body, and a display screen and a variety of control buttons are provided on the control panel.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution 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.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] Embodiment 1:

[0030] like Figure 1 to Figure 3 As shown, a sterilizing pot comprises a stainless steel pot body 1 and a pot cover 2 arranged above the stainless steel pot body 1, wherein a stainless steel inner liner 3 is arranged in the stainless steel pot body 1, and a plurality of first connecting plates 4 are arranged on the outer side of the stainless steel pot body 1, wherein the first connecting plates 4 are connected with a lifting drive member 5, and a telescopic rod 6 of the lifting drive member 5 extends upward and is connected to the pot cover 2 through a second connecting plate 7; a plurality of connecting rods 12 are arranged under the pot cover 2, and the connecting rods 12 are detachably connected with a stainless steel tray 13; and the pot cover 2 is also provided with at least a temperature sensor 8, a pressure gauge 9 and a pressure relief valve 10.

[0031] The sterilizing pot is improved in the opening structure of the pot cover 2 and the way of taking and placing the stainless steel tray 13, so that the pot cover 2 can be automatically opened and closed and the stainless steel tray 13 can be taken out. On the one hand, it can avoid manual opening of the lid, reduce labor consumption, and improve operating efficiency. On the other hand, it can avoid high temperature or high temperature steam from overflowing and injuring people when the lid is opened, and has high safety. At the same time, it is convenient for operators to take and place items directly on the pot body, which further improves operating efficiency and safety.

[0032] The pot cover 2 is a stainless steel sealed pot cover with good sealing performance; the lifting drive member 5 can directly drive the pot cover 2 to rise and fall using its telescopic rod 6, thereby realizing the opening and closing of the pot cover 2. This process can be carried out fully automatically without the need for manual use of tools to tighten bolts, screws or buckles to fix the pot cover. Especially for large-volume sterilizing pots (capacity of dozens of liters or tens of liters), it can greatly reduce the difficulty of opening and closing the pot cover and improve the efficiency of opening and closing the pot cover.

[0033] The stainless steel tray 13 is linked with the pot cover 2 through the connecting rod 12, and can rise and fall along with the pot cover 2. When the pot cover 2 is raised, the stainless steel tray 13 can be lifted above the opening of the stainless steel inner pot. At this time, it is very convenient and safe to put in or take out items from above, and it also saves the operation of manually lifting the tray or basket in the existing sterilization pot.

[0034] The first connecting plate 4 and the second connecting plate 7 are arranged as connecting parts on the outside of the stainless steel pot body and the pot cover. While playing a connecting role, they will not make the appearance structure of the entire sterilizing pot complicated. The changes to the original pot body are relatively small, and the heating and pressurizing system, water circulation system, etc. in the original pot body are not affected.

[0035] The structure of the pot cover 2 is simpler than that of the original pot cover. The temperature sensor can obtain the temperature in the pot in real time during operation. The pressure gauge (pressure sensor) is used to monitor the pressure in the pot. The pressure relief valve can relieve pressure and exhaust air before opening the cover.

[0036] Furthermore, a pot cover protrusion 201 is provided below the pot cover 2, a guide angle is provided at the lower edge of the pot cover protrusion 201, and at least one sealing ring is provided on the periphery of the pot cover protrusion.

[0037] The pot cover protrusion 201 can be matched with the upper opening of the stainless steel inner pot 3. When the pot cover is closed, the pot cover protrusion can be inserted therein, and with the cooperation of the sealing ring, a good sealing effect is formed; a sealing ring can also be provided at the matching surface of the pot cover and the stainless steel pot body to further improve the overall sealing performance. The guide angle is a rounded structure or a slope structure, which facilitates the pot cover protrusion to be pressed in from top to bottom.

[0038] Furthermore, the first connecting plate 4 is an L-shaped steel plate, and a pair of the first connecting plates 4 are symmetrically welded to the outside of the stainless steel pot body 1; the second connecting plate 7 is a horizontal steel plate, and the second connecting plate 7 is welded to the outer edge of the pot cover 2. By welding, these steel plates can be connected more firmly to form a stable connection relationship.

[0039] Furthermore, the lifting drive member 5 is an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, which can provide sufficient driving force; the lifting drive member 5 is connected to the first connecting plate 4 by a plurality of bolts, and the upper end of the telescopic rod 6 passes through the second connecting plate 7 and is connected with a locking nut. This connection method is simple and convenient, and can also be disassembled during subsequent use and maintenance.

[0040] Furthermore, the connecting rods 12 are two centrally symmetrically arranged, and the connecting rods 12 are provided with multiple sections of external threads (such as Figure 4 As shown), the external thread supports the stainless steel tray by connecting gaskets and nuts.

[0041] Depending on the depth of the sterilizing pot and the stainless steel inner tank, connecting rods 12 of different lengths can be set. For a longer connecting rod 12 (the corresponding volume of the sterilizing pot is also larger), many sections of external threads can be set on its rod body, so that multiple stainless steel trays 13 can be arranged at intervals, so that more items can be placed for sterilization operations; the stainless steel tray is fixed by using the connecting gasket and nut, which makes connection and disassembly more convenient.

[0042] Furthermore, the outer diameter of the stainless steel tray 13 is 5 to 20 mm smaller than the inner diameter of the stainless steel inner liner 3 , and the length of the connecting rod 12 is 5 to 15 mm smaller than the depth of the stainless steel inner liner 3 .

[0043] While ensuring that the stainless steel tray 13 and the connecting rod 12 can be completely accommodated in the stainless steel inner container 3, the gap between them is also controlled to facilitate gas flow and control the overall temperature rise performance.

[0044] Furthermore, a control panel 11 is provided at the lower front of the stainless steel pot body 1, and a display screen and various control buttons are provided on the control panel 11. The temperature sensor 8, the pressure gauge 9, the pressure relief valve 10 and the lifting drive 5 are respectively electrically connected to the control panel 11. A power switch and a drain valve are also provided at the lower side of the stainless steel pot body 1.

[0045] The control panel 11 can be used to conveniently control the entire sterilizer, for example, it adopts a microcomputer control system, touch buttons, digital display, and is equipped with a complete fault alarm system, and real-time fault information prompts (safer and more reliable to use); fast exhaust, slow exhaust, insulation and pressure holding time, etc. can be set; for example, the working processes such as water injection, exhaust, heating, sterilization, and drying are fully automated and do not require personnel supervision.

[0046] For example, in tissue culture or routine microbiological experiments, high-temperature steam sterilization usually requires 15 minutes of heat preservation at 121°C (i.e., steam pressure of 1kg / cm2 or 15 pounds / inch2, or 0.105MPa). This requirement generally applies to test tubes, Erlenmeyer flasks and other items with a capacity of less than 200ml. If the volume of a single item is large, especially solid culture medium, the sterilization time can be appropriately extended to avoid incomplete sterilization.

[0047] The sterilizing pot is also equipped with a heating protection device, an anti-dry burning alarm device, and an over-temperature and over-pressure protection device. When the heater exceeds the set temperature, the system automatically cuts off the power supply to the heater and displays an alarm message; when the water level is lower than the heating tube, the anti-dry burning device automatically cuts off the heating power supply and displays an alarm message; when the temperature and pressure inside the sterilizing pot exceed the safe range, the system automatically starts the temperature and pressure reduction program to ensure that the sterilized items are not damaged; when the pressure inside the sterilizing pot exceeds the set pressure, the pressure relief valve can also automatically open to release the pressure.

[0048] Embodiment 2:

[0049] The difference between this embodiment and the first embodiment is that the structure of the connecting rod is different.

[0050] Specifically, Figure 5 As shown, a plurality of hooks 14 are provided on the outer periphery of the connecting rod 12. Through the arrangement of this structure, a stainless steel tray is arranged under the rod body, which can be used to place some items with storage conditions, and these hooks 14 on the rod body can be used to hang some items that cannot be placed stably. Through the arrangement of the hooks, the diversity of item placement is improved.

[0051] Embodiment three:

[0052] The difference between this embodiment and the first embodiment is that a stainless steel tray with another structure is provided.

[0053] Specifically, Figure 6 and 7 As shown, the stainless steel tray 13 is also provided with a detachable porous protective tube 15, which is a half-detachable structure connected by magnetic blocks 16 on both sides. The stainless steel tray 13 is provided with a circle of clamping grooves, and the porous protective tube 15 can be directly clamped on the clamping grooves, so that the porous protective tube 15 can form a structure similar to a net basket with the stainless steel tray 13, which can not only place items, but also prevent some small items from falling under the tray.

[0054] The magnetic connection method is adopted to facilitate the disassembly of the porous casing 15 so that it can be removed or installed from above the stainless steel tray 13 without disassembling the stainless steel tray 13.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
