It should be noted that the features of the embodiments of the present utility model may be combined with each other without conflict.

As described in the background art, in the process of vacuum sterilization of materials, the sterilization chamber usually maintains a high temperature state for sterilization treatment, but after sterilization, the sterilization chamber has a problem of slow cooling, and the real-time temperature of the sterilization chamber needs to be continuously detected.

Referring to fig. 1 and 2, a vacuum sterilization system 100 according to an embodiment of the present utility model can solve the above-mentioned problems, and will be described in detail.

The vacuum sterilization system 100 includes a sterilization chamber 110, a vacuum pump 120, and a water tank 130;

The sterilization chamber 110 has an inner chamber 111 and an interlayer 112, the interlayer 112 surrounds the outer side of the inner chamber 111, the vacuum pump 120 is communicated with the inner chamber 111, and the water tank 130 is communicated with the interlayer 112.

This vacuum sterilization system 100 can carry out the evacuation operation to inner room 111 and intermediate layer 112 through vacuum pump 120 earlier when needs cooling, adds the cooling water to intermediate layer 112 by water tank 130 again, absorbs the heat through the cooling water, and then realizes quick cooling for need not to last the detected temperature again after the cooling, thereby improves the operating efficiency.

It should be noted that, before the sterilization operation, the vacuum pump 120 may perform a vacuum treatment on the inner chamber 111, so as to avoid the residual gas in the inner chamber 111 from affecting the sterilized material. After the sterilization operation, the vacuum pump 120 may also perform a vacuum process on the inner chamber 111, so as to avoid the too slow cooling rate caused by the high temperature gas residue in the inner chamber 111.

In addition, the pipe line between the vacuum pump 120 and the inner chamber 111 penetrates through the interlayer 112, and performs sealing treatment at the penetrating position, so as to prevent the medium in the interlayer 112 from leaking.

Referring to fig. 2, the interlayer 112 is provided with a verification port 113 therethrough, and the verification port 113 communicates with the inner chamber 111.

In the above technical solution, by providing the verification port 113, it is convenient to install a temperature sensor to detect the temperature of the inner chamber 111.

Notably, the temperature sensor may be long-term installed in the verification port 113 to detect the temperature of the inner chamber 111 in real time; the temperature sensor may be intermittently inserted into the verification port 113, and when the temperature sensor is inserted into the verification port 113, the verification port 113 needs to be double-layer sealed, the inner layer seals the side wall of the inner chamber 111, and the outer layer seals the side wall of the interlayer 112, so that the inner chamber 111 and the interlayer 112 are prevented from being conducted with the outside to generate sterile gas overflow.

Of course, because the sterile gas is in a high temperature or high oxidation state, if there is a great safety hazard due to overflow, the plug-in temperature sensor needs to be placed in the verification port 113 for temperature information acquisition after the vacuum pump 120 performs the vacuum pumping operation on the inner chamber 111.

And, the vacuum sterilization system 100 further includes two pressure sensors 190 and two safety valves 192, wherein the two pressure sensors 190 are respectively used for acquiring the real-time pressure in the inner chamber 111 and the interlayer 112, and the two safety valves 192 are respectively used for protecting the inner chamber 111 and the interlayer 112, so that the two pressure sensors can be depressurized under the condition of overlarge internal air pressure to ensure the safety of the sterilization chamber 110.

Referring to fig. 1 and 2, the vacuum sterilization system 100 further includes a first air inlet branch 140, the first air inlet branch 140 being in communication with the interlayer 112.

In the above technical solution, the first air inlet branch 140 is communicated with the interlayer 112 for delivering industrial steam, so as to perform heat preservation and insulation operation on the inner chamber 111 during sterilization operation.

It is noted that the second inlet branch 145 may be provided with two inputs, which are in communication with a supply line of clean air or pure steam, respectively. Of course, the input end of the second air inlet branch 145 may be connected to a three-way structure, and further connected to a clean air or pure steam supply pipeline.

When multiple mediums need to be added to the inner chamber 111, the second air inlet branch 145 may also have three, four, etc. input ends, or a four-way or five-way structure may be connected to the input end of the second air inlet branch 145, so as to ensure that multiple mediums can be smoothly added to the inner chamber 111.

And, a plurality of media may be simultaneously added so that the media may be mixed in advance before entering the inner chamber 111 to increase the media mixing speed; multiple sequential addition in a specific order can also be used to avoid premature mixing of the media prior to entry into the chamber 111, thereby substantially ensuring that the functionality of each media is fully utilized.

Specifically, the second air inlet branch 145 is provided with a filter 150, and the filter 150 is provided to filter the second air inlet branch 145, so that the effect of sterilization is prevented from being affected by the mixing of impurities.

Of course, the filters 150 may be installed on the first air inlet branch 140, the third air inlet branch 148, the first water inlet branch 160 and the second water inlet branch 165, so as to filter and intercept impurities possibly existing in each pipeline when the medium is conveyed, and the specific type of the filters 150 may be selected according to different types and sizes of the impurities, so that efficient operation of the whole vacuum sterilization system 100 is ensured.

In this embodiment, the vacuum sterilization system 100 further includes a third air intake branch 148, wherein the third air intake branch 148 is configured to communicate with a solenoid valve, a cylinder, etc. for delivering compressed air as a power source.

Similarly, it is of course possible to install a solenoid valve or a manual ball valve on the third air intake branch 148 in order to ensure the accuracy of the on-off control of the third air intake branch 148.

Referring to fig. 1, the vacuum sterilization system 100 further includes a first water inlet branch 160, the first water inlet branch 160 being in communication with both the vacuum pump 120 and the water tank 130.

In the above-described embodiments, the first water inlet branch 160 is used to supply water to the vacuum pump 120 and the water tank 130.

Specifically, the first water inlet branch 160 is provided with a check valve 170 for ensuring that the water can flow in one direction in the first water inlet branch 160, thereby preventing the occurrence of reverse flow.

Of course, in order to ensure the accuracy of the on-off control of the first water inlet branch 160, a solenoid valve or a manual ball valve may be installed on the first water inlet branch 160.

Referring to fig. 1, the vacuum sterilization system 100 further includes a second water inlet branch 165, an input end of the second water inlet branch 165 is connected to the water tank 130, and an output end of the second water inlet branch 165 is connected to the vacuum pump 120.

Specifically, the second water inlet branch 165 is provided with a check valve 170 for ensuring that the water can flow in one direction in the second water inlet branch 165, thereby avoiding the occurrence of reverse flow.

Referring to fig. 1, the water tank 130 is provided with an outer drain pipe 180.

In the above technical solution, the water tank 130 may drain the stored water through the drain pipe 180, so as to avoid the water from being degraded or bacteria from growing when the water is stored in the water tank 130 for too long.

In order to ensure the one-way flow of the water in the drain pipe 180, the check valve 170 may be attached to the drain pipe 180, thereby avoiding the need for the reverse flow of the water in the drain pipe.

It should be noted that an electromagnetic valve may be installed on the outer drain pipe 180, so as to implement intelligent control on and off of the outer drain pipe 180.

Of course, a manual ball valve may be mounted on the outer tube 180, and the on/off of the outer tube 180 may be controlled manually.

In addition, in order to improve the intelligent detection to the water level of the water tank 130, a liquid level meter is arranged in the water tank 130, and the water level information in the water tank 130 is fed back in time through the liquid level meter, so that the water level of the water tank 130 is prevented from being too high or too low.

The vacuum sterilization system 100 further includes a control box, which may be mounted on the vacuum pump 120 or the water tank 130, or may be spaced apart from the vacuum pump 120 and the water tank 130.
