[0004] Although the electric push rod is provided in the prior art 1 to facilitate the removal of items from the sterilizer, the saturation of the steam has a great influence on its protein inactivation or denaturation ability. In order to ensure the sterilization effect of the steam sterilizer, saturated steam must be used. In the prior art, the steam directly introduced into the sterilizer from the boiler through the pipeline will inevitably lose heat, and droplets will condense in the saturated steam. When some of the droplets are mixed with the saturated steam and enter the sterilizer body, the sterilization effect will be affected. Utility Model Content

[0005] The utility model aims to provide a vertical pressure steam sterilizer, which can solve the problem in the prior art that the steam directly introduced into the sterilizer will condense into droplets due to heat loss during the process of being transported from the boiler through a pipeline, thus affecting the sterilization effect.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0021] When the driving device installed on the outlet pipe assembly drives the inlet pipe assembly to rotate, under the action of the water retaining part connected to the inlet pipe assembly, the steam and droplets flowing into the inlet pipe assembly rotate together. Since the droplets are more affected by the centrifugal force than the steam, the liquid adheres to the water retaining plate under the action of the centrifugal force, further accelerating the efficiency and effect of separating the steam and droplets in the steam.

[0037] The air inlet pipe assembly 103 is rotatably mounted on the air outlet pipe assembly 102 from top to bottom, and the air outlet pipe assembly 102 is connected to the steam generator through the air inlet pipe assembly 103; a driving device 104 for driving the air inlet pipe assembly 103 to rotate is mounted on the air outlet pipe assembly 102, and a gas flow channel is formed between the air outlet pipe assembly 102 and the air inlet pipe assembly 103, and the air outlet pipe is connected to the gas flow channel;

[0038] A drain valve 105 for draining condensed water is installed at the bottom end of the air outlet pipe assembly 102 , and a water retaining portion 106 is connected to the air inlet pipe assembly 103 .

[0039] In the present invention, the sterilizer body 101 is used to place items to be sterilized, and the steam generator is used to produce steam and input the steam into the air inlet pipe assembly 103. The steam entering the air inlet pipe assembly 103 first flows from top to bottom along the inside of the air inlet pipe assembly 103, and the steam flowing to the outlet at the lower end of the air inlet pipe assembly 103 flows from bottom to top again through the gap between the air inlet pipe assembly 103 and the air outlet pipe assembly 102; by installing the air inlet pipe assembly 103 on the outlet organ assembly, the flow distance of the steam can be increased. During the flow of steam in the air inlet pipe assembly 103 and the gas flow channel, when the droplets generated in the steam are blocked by the water retaining portion 106, they will adhere to the water retaining portion 106 under the action of inertia, and the steam will bypass the water retaining portion 106 and flow away; the droplets that come into contact with the water retaining portion 106 flow to the steam trap under the action of their own gravity, and finally The steam is finally discharged through the steam trap, which reduces the content of droplets in the high-temperature steam; the steam without droplets enters the sterilizer body 101 through the connection between the air outlet pipe assembly 102 and the sterilizer body 101, and sterilizes the items placed in the sterilizer body 101; when the driving device 104 installed on the air outlet pipe assembly 102 drives the air inlet pipe assembly 103 to rotate, under the action of the water retaining part 106 connected to the air inlet pipe assembly 103, the steam and droplets flowing into the air inlet pipe assembly 103 rotate together, because the droplets are more affected by the centrifugal force than the steam, the liquid adheres to the water retaining part 106 under the action of the centrifugal force, which further accelerates the efficiency and effect of the separation of steam and droplets in the steam; the steam generator and steam trap recorded in this embodiment are both conventional industrial devices that can be used to manufacture and input steam in the prior art, and their specific structures and functions are no longer described one by one in this embodiment.

[0040] Specifically, the air outlet pipe assembly 102 includes an outer sleeve 107 and a branch pipe 108, the outer sleeve 107 is connected to the sterilizer body 101 through the branch pipe 108, and the air inlet pipe assembly 103 is rotatably mounted on the outer sleeve 107. The steam flowing from bottom to top through the gap between the air inlet pipe assembly 103 and the air outlet pipe assembly 102 enters the sterilizer body 101 through the branch pipe 108, and sterilizes the objects placed in the sterilizer body 101.

[0041] Specifically, the air inlet pipe assembly 103 includes an inner sleeve 109 and a rotary joint 110. The inner sleeve 109 is rotatably mounted on the outer sleeve 107. The inner sleeve 109 is connected to the steam generator through the rotary joint 110. The driving device 104 is mounted on the outer sleeve 107 and is used to drive the inner sleeve 109 to rotate. The water retaining portion 106 is fixedly connected to the inner wall of the inner sleeve 109. When the inner sleeve 109 rotates under the drive of the driving device 104, the water retaining portion 106 disturbs the gas steam entering the inner sleeve 109, so that after the steam is centrifuged, the liquid in the steam is separated from the steam and flows to the steam trap under the action of its own gravity to be discharged, and the gas flow channel is formed between the inner sleeve 109 and the outer sleeve 107.

[0042] Specifically, the water retaining parts 106 are staggered from top to bottom in the inner sleeve 109. By staggering and fixing the water retaining parts 106 in the inner sleeve 109, the flow path of the steam containing the droplets can be increased while further increasing the probability of the droplets directly contacting the water retaining parts 106, thereby improving the dewatering effect.

[0043] Specifically, the water retaining portion 106 is tilted downwards. By tilting the water retaining portion downwards, the liquid droplets attached to the water retaining portion 106 can be discharged through the steam trap after sliding down the water retaining portion 106 .

[0044] Specifically, the inner sleeve 109 is coaxially connected with a mounting portion 112, the outer sleeve 107 is provided with a slide rail 113, and the mounting portion 112 is provided with a slide groove 114, and the mounting portion 112 is rotatably mounted on the outer sleeve 107 through the slide groove 114. After the mounting portion 112 is rotatably mounted on the outer sleeve 107 through the slide groove 114, the slide rail 113 slidably matched with the slide groove 114 limits and guides the mounting portion 112, so that the mounting portion 112 and the inner sleeve 109 connected to the mounting portion 112 rotate more smoothly under the drive of the driving device 104.

[0045] Specifically, the mounting portion 112 is detachably connected to the inner sleeve 109. The mounting portion 112 is detachably connected to the inner sleeve 109 via bolts, so that the inner sleeve 109 can be easily installed and replaced.

[0046] Specifically, a sealing ring is rotatably mounted on the outer sleeve 107 , and the sealing ring is used to seal the gap between the outer sleeve 107 and the inner sleeve 109 .

[0047] Specifically, the driving device 104 includes a driving motor 115, a driving gear 116 and a driven gear 111. The driving motor 115 is installed on the outer sleeve 107. The driving gear 116 is connected to the output end of the driving motor 115. The driven gear 111 is sleeved on the mounting portion 112 and meshes with the driving gear 116. The driving gear 116 is fixedly sleeved on the output end of the driving motor 115. The driven gear 111 is coaxially fixedly connected with the mounting portion 112. When the driving motor 115 drives the driving gear 116 to rotate, it drives the driven gear 111 and the mounting portion 112 to rotate, so that the water retaining portion 106 disturbs the steam after the inner sleeve 109 rotates.

[0048] Specifically, the drain valve 105 is threadedly connected to the outer sleeve 107. By threading the drain valve 105 to the outer sleeve 107, the drain valve 105 can be easily installed and replaced.
