Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment technology, and in particular to a high-pressure sterilizer. Background Technology

[0002] An autoclave is a specialized device that kills microorganisms through a high-temperature, high-pressure environment. It is widely used in medical, scientific research, food processing, and biopharmaceutical fields for sterilizing medical devices, laboratory equipment, food ingredients, and other items. As a device capable of effectively killing bacteria, viruses, and other microorganisms, the autoclave plays a crucial role. However, some existing autoclaves currently have shortcomings in practical applications.

[0003] In terms of storage structure, most traditional autoclaves have a fixed and simple storage frame structure. On the one hand, it is difficult to flexibly adjust and divide the space according to the size, shape and quantity of the items to be sterilized. This results in low space utilization and disorderly placement of items when placing different types of items. This may not only affect the sterilization effect, but also increase the cumbersomeness of operation. On the other hand, the installation guidance stability of the storage frame in the sterilization chamber is insufficient. It is easy to shake or tilt during the process of pushing or taking out, which may even cause items to fall and be damaged. It also causes inconvenience to operators and poses certain safety hazards. Summary of the Invention

[0024] The present invention will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] like Figure 1-7 As shown, an autoclave includes an outer shell 1, a sterilization chamber 3, an end cap 2, and multiple storage frames 4. The outer shell 1 is a rectangular frame structure, and the sterilization chamber 3 is fixedly installed inside by bolts. The sterilization chamber 3 is cylindrical, and its upper opening is sealed to the end cap 2 by a sealing ring. Multiple storage frames 4 are stacked inside the sterilization chamber 3, and the bottom is supported by a support plate 26 fixed to the inner wall of the sterilization chamber 3 by bolts. The support plate 26 is a triangular structure and is located directly above the heating tube 5, which facilitates steam circulation and can support the weight of the storage frames 4.

[0026] The sterilization chamber 3 has symmetrically fixed first U-shaped blocks 6 on its left and right sides, with the openings of the first U-shaped blocks 6 facing the center of the sterilization chamber 3. Each storage box 4 has a first guide block 7 welded to its left and right side walls. The first guide block 7 slides into the groove of the first U-shaped block 6 to ensure that the storage box 4 moves stably in the vertical direction when pushed in or taken out, avoiding shaking or tilting.

[0027] like Figure 6 As shown, the storage frame 4 is a circular frame. Multiple 20mm diameter ventilation holes are evenly opened on the side wall and bottom of the storage frame 4 to facilitate steam penetration and sterilization, forming a steam circulation channel. Each storage frame 4 has a handle 14 rotatably connected to both sides by a pin. The handle can be rotated upwards by 90° for easy handling.

[0028] The divider 8 is an inverted T-shaped metal frame that is slidably installed inside the storage frame 4. Two divider plates 9 are respectively fitted onto the longitudinal rod in the middle of the divider 8 and can be slidably adjusted along the rod. The divider plates 9 and the divider 8 are both fixed with second guide blocks 11, which slide and cooperate with the second U-shaped blocks 12 on the inner wall of the storage frame 4 to ensure that the divider plates 9 remain stable when adjusted.

[0029] Meanwhile, the partition plate 9 is provided with an M5 specification limit thread hole. After the limit bolt 10 passes through the thread hole, the end of the limit bolt 10 is tightly abutted against the top surface of the rod of the partition frame 8. The position of the partition plate 9 can be locked by rotating the limit bolt 10, so as to realize the flexible division of the storage space. The top center of the partition frame 8 is connected to a lifting ring 13 by thread, which makes it easy to lift the partition frame and partition plate as a whole by hook, so as to facilitate replacement or cleaning.

[0030] like Figure 1As shown, the locking mechanism of the end cover 2 includes a connecting post 19 welded to the left side of the outer shell 1. An arc-shaped pressure plate 20 is rotatably mounted on the upper end of the connecting post 19 via a pin. The arc of the arc-shaped pressure plate 20 matches the top contour of the end cover 2. A limit post 21 is fixed on the right side of the outer shell 1. The top of the limit post 21 is hemispherical. When the end cover 2 is closed, the right end of the arc-shaped pressure plate 20 is inserted into the groove of the limit post 21. By rotating the adjusting screw 22, the handle of which is a round handle 23, the limit block at the lower end of the adjusting screw 22 is pressed against the top surface of the end cover 2, thereby achieving a sealed fixation.

[0031] A safety valve 24 is installed in the center of the top surface of the end cap 2. When the pressure inside the sterilization chamber 3 exceeds 0.2MPa, the valve will automatically open to release pressure and ensure the safety of the equipment.

[0032] A pressure gauge 15 is installed on the front of the outer casing 1 to display the air pressure inside the sterilization chamber in real time. A PLC control panel 16 is set on the right side, which integrates temperature and time setting buttons and heating tube start / stop switch. The sterilization process is automatically controlled by a preset program. Self-locking casters 25 are installed at the four corners of the bottom of the outer casing 1 for easy movement of the equipment. The casters are locked after the equipment is in place to prevent slippage.

[0033] like Figure 2 As shown, the sterilization chamber 3 has an inlet pipe and an outlet pipe welded to the bottom, which pass through the side wall of the outer shell 1 respectively. One end of the inlet pipe is connected to an external water source such as a distillation water machine, and the other end is equipped with an inlet valve 18 for injecting clean water into the sterilization chamber. One end of the outlet pipe is connected to the drain port at the bottom of the sterilization chamber 3, and the other end is equipped with a drain valve 17. After sterilization, the drain valve 17 is opened to discharge wastewater.

[0034] In use, adjust the internal partition space of the storage box 4 by sliding the partition plate 9 according to the size of the items to be sterilized, fix it with the limit bolt 10, put the items into the storage box 4, push the storage box into the sterilization box 3 along the first U-shaped block 6 through the handle 14, and stack it on the support plate 26.

[0035] Close end cap 2, rotate arc-shaped pressure plate 20 to engage limit post 21, rotate adjusting screw 22 to press end cap tight; set temperature and time through PLC control panel 16, start heating tube 5.

[0036] Heating tube 5 heats water to generate steam. The steam penetrates the items evenly through the vent holes of storage frame 4. Pressure gauge 15 displays the pressure in real time. When the pressure rises to 0.1MPa, the corresponding temperature is 121℃. Sterilization is completed after maintaining the set time.

[0037] After sterilization, the safety valve 24 automatically releases the residual pressure. When the pressure drops to 0, the end cover 2 is opened, the storage box 4 is taken out, and the wastewater is discharged through the drain valve 17 to clean the equipment.
