Description

Technical Field

[0001] This utility model belongs to the field of ultra-high pressure processing equipment, specifically relating to an ultra-high pressure processing equipment based on a gas medium. Background Technology

[0002] Existing ultra-high pressure sterilization equipment for materials generally uses liquid media for pressurization, such as oil, water, and alcohol. However, when using these liquid media to treat materials, the media residue is prone to occur, thus affecting the quality of the materials. If inert gas media such as carbon dioxide and nitrogen are used to treat materials, the above problem does not exist. However, existing gas booster pumps cannot directly meet the pressure required for ultra-high pressure treatment, thus making the idea of ​​using gas media for ultra-high pressure treatment impossible. Therefore, there is an urgent need to design an ultra-high pressure treatment equipment based on gas media. Utility Model Content

[0004] An ultra-high pressure processing device based on a gas medium includes a high-pressure cylinder. A plunger is slidably installed in the inner cavity of the high-pressure cylinder. The inner cavity of the high-pressure cylinder is connected to one interface of a first four-way pipe. The other three interfaces of the first four-way pipe are respectively connected to a pressure relief valve, a pressure sensor, and a shut-off valve. The other end of the shut-off valve is connected to a one-way valve through a pipeline. The other end of the one-way valve is connected to the outlet of a booster pump through a pipeline. The inlet of the booster pump is connected to a medium input pipe.

[0005] Furthermore, the flow direction of the medium inside the one-way valve is from the booster pump side to the shut-off valve side.

[0012] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figure 1 An ultra-high pressure processing device based on a gas medium includes a high-pressure cylinder 1. A plunger is slidably installed in the inner cavity of the high-pressure cylinder 1. The bottom of the inner cavity of the high-pressure cylinder 1 is connected to one interface of a first four-way pipe 2 through a pipeline. The other three interfaces of the first four-way pipe 2 are respectively connected to a pressure relief valve 3, a pressure sensor 4, and a shut-off valve 5. The other end of the shut-off valve 5 is connected to a one-way valve 6 through a pipeline. The other end of the one-way valve 6 is connected to the outlet of a booster pump 7 through a pipeline. The inlet of the booster pump 7 is connected to a medium input pipe 8. The other end of the medium input pipe 8 is connected to a gas medium storage tank.

[0014] In this embodiment, the flow direction of the medium in the one-way valve 6 is from the side of the booster pump 7 to the side of the shut-off valve 5. The one-way valve 6 can restrict the flow direction of the medium, so that the medium can only flow to the side of the high-pressure cylinder 1 through the one-way valve 6 and cannot flow back, thereby avoiding the depressurization of the high-pressure cylinder 1.

[0015] In this embodiment, the medium input pipe 8 is connected to an explosion-proof valve 11 and a safety valve 10, which can ensure the safety of related equipment and pipelines during the pressurization process of the booster pump 7.

[0016] In this embodiment, a second four-way pipe 9 is connected to the medium input pipe 8, and the explosion-proof valve 11 and the safety valve 10 are respectively connected to the other two ports of the second four-way pipe 9.

[0017] In this embodiment, the gas medium used for pressurization can be an inert, non-toxic, and harmless gas such as carbon dioxide or nitrogen.

[0018] The process for handling related materials using the equipment of this utility model is as follows:

[0019] First, the material to be processed is added to the inner cavity of the high-pressure cylinder 1. Then, the plunger is installed into the high-pressure cylinder 1 to close it. The shut-off valve 5 and the check valve 6 are opened, and the booster pump 7 is turned on to fill the high-pressure cylinder 1 with gas medium and gradually increase the pressure to a certain level. The shut-off valve 5 is closed, and then pressure is applied to the plunger, causing the plunger to move inside the high-pressure cylinder 1 and gradually compress the space inside the high-pressure cylinder 1, thereby increasing the pressure inside the high-pressure cylinder 1 to a large value and maintaining the pressure for a period of time to achieve full processing of the material. During the pressurization process, the pressure sensor 4 can monitor the pressure inside the high-pressure cylinder 1 in real time, which facilitates precise pressure control. After processing is completed, the pressure relief valve 3 is opened to release the pressure, and then the high-pressure cylinder 1 is opened to remove the material inside.

[0020] In this invention, the combination of the booster pump 7 and the plunger in the high-pressure cylinder 1 enables the use of gas medium to perform ultra-high pressure sterilization on the material in the high-pressure cylinder 1. Furthermore, using gas medium for ultra-high pressure sterilization not only improves the treatment effect but also eliminates the problem of medium residue on the material.

[0021] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
