Description

Passive vacuum storage tank with air ejector
Technical Field
The invention belongs to the technical field of vacuum storage, and particularly relates to a passive vacuum storage tank (cabinet) with an air ejector.
Background
Along with the continuous improvement of living standard, the requirement of people on storage is higher and higher, the stored articles are medicines, out-of-season clothes, books and the like besides common food, and people often put the articles into a traditional box and store the articles in a plastic bag of the plastic box, so that the problems of mildew, moth and the like are particularly serious in a humid place, especially in the plum rain season every year in south China, and the service life of the articles is greatly shortened. The vacuum storage technology can fundamentally solve the problem of sealed storage, and the time for the stored articles to become damp, mildew and oxidize and deteriorate can be effectively prolonged by forming vacuum storage in a low-oxygen low-pressure (negative pressure) state in the vacuum storage tank (cabinet).
The prior art mainly adopts two methods, namely a manual vacuum pump and an electric vacuum pump. The manual vacuum pump has poor vacuum pumping performance and cannot ensure the vacuum degree. The electric vacuum pump needs to consume electric energy to produce vacuum, and when the electric energy is continuously in shortage, the electric vacuum pump loses the function. The energy-saving electric vehicle is not suitable for being used in scenes with energy shortage or lack, such as field scientific research teams, frontier troops and the like. In addition, the electric vacuum pump has the advantages of complex structure, more parts and higher failure rate, and the application range of the electric vacuum pump is reduced. Therefore, the electric vacuum pump which needs to be additionally provided with electric energy to work cannot meet the defects of working under a passive condition, reliability and the like, and needs further improvement.
Disclosure of Invention
In order to solve the problems in the prior art, the invention aims to design a passive vacuum storage tank with an air ejector, which does not need the consumption of external electric energy under the condition of not excessively complicating a system, and only depends on manpower to work to obtain higher vacuum degree.
In order to achieve the purpose, the technical scheme of the invention is as follows: a passive vacuum storage tank with an air ejector comprises a manpower-driven inflating pump, a one-way valve a, a pressure gauge a, the air ejector, a one-way valve b, a pressure gauge b, a vacuum storage tank and a vacuum breaker valve;
the inlet of the manpower-driven inflating pump is directly communicated with the atmosphere, and the outlet of the manpower-driven inflating pump is connected with the inlet of the one-way valve a through a gas pipeline;
the outlet of the one-way valve a is connected with the working fluid inlet of the air ejector through a pipeline;
the pressure gauge a is arranged at a working fluid inlet of the air ejector and used for displaying the pressure of the working fluid of the air ejector;
an injection fluid inlet of the air ejector is connected with an outlet of the one-way valve b, and an outlet of the air ejector is communicated with the atmosphere through a pipeline; the inlet of the one-way valve b is connected with the vacuum storage tank through a pipeline;
the pressure gauge b is arranged at an injection fluid inlet of the air ejector and used for displaying the pressure of injection fluid of the air ejector, namely the pressure in the vacuum storage tank;
the vacuum breaking valve is arranged at the top of the vacuum storage tank.
Further, the vacuum storage tank is replaced by a vacuum storage cabinet or a vacuum storage container.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention utilizes the air ejector to produce vacuum, effectively avoids the problems of poor vacuum pumping performance and insufficient vacuum degree of the traditional manual vacuum pump, and ensures the storage quality of articles.
2. According to the invention, the manual-drive inflating pump is used as a working fluid source of the air ejector during vacuum pumping, so that the problems that the electric vacuum pump cannot work under the condition of shortage of electric energy, the structure is complex, and the failure rate is high are effectively solved, the storage under a passive condition is ensured, the high vacuum degree is obtained only by manpower, and the vacuum pump is suitable for working under a special scene (passive).
Drawings
FIG. 1 is a schematic composition diagram of the present invention.
In the figure: 1. the manual driving type inflating pump comprises a manual driving type inflating pump body 2, check valves a and 3, pressure gauges a and 4, an air ejector 5, check valves b and 6, pressure gauges b and 7, a vacuum storage tank 8 and a vacuum breaking valve.
Detailed Description
The invention is explained in more detail below with reference to the figures and examples. As shown in fig. 1, a passive vacuum storage tank with an air ejector comprises a manpower-driven inflating pump 1, a one-way valve a2, a pressure gauge a3, an air ejector 4, a one-way valve b5, a pressure gauge b6, a vacuum storage tank 7 and a vacuum breaking valve 8;
the inlet of the manpower-driven inflating pump 1 is directly communicated with the atmosphere, and the outlet is connected with the inlet of a one-way valve a2 through a gas pipeline;
the outlet of the one-way valve a2 is connected with the working fluid inlet of the air ejector 4 through a pipeline;
the pressure gauge a3 is arranged at the working fluid inlet of the air ejector 4 and is used for displaying the pressure of the working fluid of the air ejector 4;
the injection fluid inlet of the air ejector 4 is connected with the outlet of the one-way valve b5, and the outlet of the air ejector 4 is communicated with the atmosphere through a pipeline; the inlet of the one-way valve b5 is connected with the vacuum storage tank 7 through a pipeline;
the pressure gauge b6 is arranged at the injection fluid inlet of the air ejector 4 and is used for displaying the pressure of the injection fluid of the air ejector 4, namely the pressure in the vacuum storage tank 7;
the vacuum break valve 8 is installed on the top of the vacuum canister 7.
Further, the vacuum storage tank 7 is replaced with a vacuum storage cabinet or a vacuum storage container.
The working process of the invention is as follows:
vacuum storage tank 7 arranges the plane in, operating personnel is through observing the pressure value of manometer b6, when for malleation (atmospheric pressure), operating personnel is through self strength drive manpower drive inflating pump 1, the produced high-pressure gas of manpower drive inflating pump 1 passes through check valve a2 and gets into air ejector 4, thereby draw the air in the vacuum storage tank 7 through check valve b5, and draw the required vacuum of ejection in vacuum storage tank 7 inside, export discharge mist to the atmosphere from air ejector 4. When an operator observes that the pressure gauge b6 is in a calibrated vacuum degree, high-pressure gas generated by the manual driving type inflating pump 1 stops entering the air ejector 4, and the whole device stops supplying air. When an operator needs to take out the articles stored in the vacuum storage tank 7 in a vacuum state, the entry of outside air can be realized by actuating the vacuum breaking valve 8, the vacuum environment inside the vacuum storage tank 7 is broken, and the vacuum storage tank 7 can be opened to take out the articles. When the vacuum degree of the vacuum storage tank 7 is insufficient or the vacuum needs to be pumped again, an operator pumps high-pressure gas into the air ejector 4 through the manual driving type inflating pump 1 through the one-way valve a2, and when the pressure gauge b6 reaches the calibrated vacuum degree again, the operator stops driving the manual driving type inflating pump 1 and stops pumping the high-pressure gas into the air ejector 4.
The present invention is not limited to the embodiment, and any equivalent idea or change within the technical scope of the present invention is to be regarded as the protection scope of the present invention.
