Description

Technical Field

[0001] This utility model relates to the field of steam sterilization technology, and in particular to a vertical pressure steam sterilization device. Background Technology

[0002] A vertical pressure steam sterilizer is a vertically placed device that uses high-temperature, high-pressure saturated steam for sterilization. It is primarily used in medical, laboratory, and industrial fields for sterilizing instruments, dressings, culture media, and other items. Its core structure includes a sterilization chamber, a sealing cap, a pressure vessel, a heating system, a control system, and safety devices. During operation, steam is generated through electric heating, creating a high-pressure, high-temperature environment within the sealed chamber. The temperature is typically 121℃-134℃, and the pressure is 0.1-0.2 MPa. The latent heat of the steam penetrates the items to achieve efficient sterilization. Compared to horizontal structures, the vertical design occupies less space, making it suitable for locations with limited space.

[0003] A search revealed that patent CN222426714U discloses a vertical pressure steam sterilization device. The device is connected to an air inlet via an air pump. The air pump is then used to inflate the air inlet, causing two air bladders to expand and press tightly against the inner wall of the limiting groove, effectively ensuring a high-pressure environment inside the vessel.

[0004] Existing vertical sterilization devices share the same drawbacks as this device: the access port is located at the top, the bottom is the water heating zone, the top is the item placement area, and the steam outlet is in the center. When items are placed at the top for sterilization, their position is fixed, resulting in insufficient steam penetration at the contact surface and affecting the sterilization effect. Secondly, the top location of the access port makes it inconvenient to retrieve and place items. Therefore, further improvements are needed. To this end, we propose a vertical pressure steam sterilization device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a vertical pressure steam sterilization device is disclosed, comprising a cabinet 1, a partition 4 fixed to the bottom of the cabinet 1, and several ventilation holes 41 provided on the partition 4. The side of the cabinet 1 above the partition 4 is open, and a side door 2 is connected to the side of the cabinet 1 near the open by a hinge. A fixing component 3 for fixing the side door 2 is provided on the outer side wall of the cabinet 1 away from the hinge. A shelf 5 is provided above the partition 4. A geared motor 6 for driving the shelf 5 to rotate is fixed on the upper surface of the cabinet 1. An electric heater 7 is fixedly installed at the bottom of the inner side wall of the cabinet 1. A water supply pipe 8 is fixed on the side wall of the cabinet 1 below the partition 4. A controller is provided on the surface of the side door 2.

[0025] In this embodiment, the controller is a Siemens SIMATIC S7-1500 CPU 1516-3PN / DP (6ES7516-3AN00-0AB0), which controls the operation of various electronic components of the device.

[0026] The top of the water inlet pipe 8 is connected to a sealing cap 9 via a threaded rotation.

[0027] Water can be added to the bottom of cabinet 1 through water inlet pipe 8. After adding water, screw the sealing cap 9 onto the top of water inlet pipe 8 to ensure the bottom of cabinet 1 is sealed.

[0028] The electric heater 7 is electrically connected to the controller, and a transparent viewing window 12 is installed on the bottom side wall of the cabinet 1.

[0029] The electric heater 7 uses the same technology as existing steam sterilization devices. The electric heater 7 is operated by a controller. The electric heater 7 heats the water at the bottom of the cabinet 1. The heated water generates steam. The steam then rises through the vent holes 41 on the partition 4, thereby using the steam to sterilize the items on the shelf 5.

[0030] An automatic pressure relief valve 10 is fixedly installed on the top wall of cabinet 1.

[0031] In this embodiment, the automatic pressure relief valve 10 adopts the same technology as the existing steam sterilization device. When the air pressure inside the cabinet 1 reaches the upper limit, the automatic pressure relief valve 10 releases the pressure inside the cabinet 1 to prevent the air pressure inside the cabinet 1 from being too high.

[0032] A pressure gauge 11 is installed on the surface of side door 2.

[0033] Pressure gauge 11 can monitor the pressure value inside cabinet 1 in real time for user reference.

[0034] The shelf 5 includes a mesh plate 51 horizontally set above the partition 4. The upper surface of the mesh plate 51 is fixed with brackets 52 on both sides. The top of the brackets 52 is fixedly connected to the output shaft of the geared motor 6.

[0035] Both the mesh plate 51 and the support 52 are made of stainless steel, and the support 52 is fixedly connected to the output shaft of the geared motor 6 with bolts. When in use, the items to be sterilized are placed on the surface of the mesh plate 51. During the steam rise process, the steam can pass through the mesh plate 51 to sterilize the items on its surface.

[0036] The fixing component 3 includes an L-shaped plate 31 hinged to the surface of the cabinet 1. The L-shaped plate 31 is connected to a screw 32 through the side away from the cabinet 1 and is rotatably connected by a screw. A handle 33 is fixedly connected to the end of the screw 32 away from the cabinet 1. The side door 2 is provided with a positioning groove for screwing in the screw 32. A sealing strip is provided at the contact position between the side door 2 and the cabinet 1.

[0037] After closing side door 2, rotate L-shaped plate 31 to one side of side door 2 so that screw 32 faces the surface of side door 2. Then rotate handle 33 to move screw 32 so that screw 32 is screwed into positioning groove. Rubber sleeve can be fitted on the end surface of screw 32 to protect the surface of side door 2. Screw 32 is used to press side door 2 to fix side door 2. Sealing strip ensures that the inside of cabinet 1 is completely sealed after side door 2 is closed.

[0038] Working principle: Rotate to open the side door 2, place the items to be sterilized on the upper surface of the mesh plate 51 and close the side door 2. Use the fixing component 3 to fix the side door 2. Then start the electric heater 7 to heat the water at the bottom of the cabinet 1. The steam generated by heating rises through the vent hole 41, thereby sterilizing the items placed on the surface of the mesh plate 51. At the same time, start the reduction motor 6 to drive the shelf 5 to rotate, thereby rotating the items, so that the steam can sterilize the items evenly and improve the sterilization effect.
