It generally has a relatively high height and can make full use of the vertical space to store a large amount of rice. There is a feeding port at the top of the silo for receiving the input of rice; there is a discharging port at the bottom for discharging the rice when needed.

[0003] Chinese Patent with application number 202223470573.X discloses a vertical silo for storing rice, which includes a vertical silo body. The vertical silo body includes support feet and a silo body. The silo body includes an outer plate and an inner plate. There is a drying layer between the outer plate and the inner plate. A rotating motor is fixedly installed at the top of the silo body. The driving end of the rotating motor faces downward and is connected with a rotating rod. The rotating rod extends to the lower part inside the silo body and an "S" stirring ring and an "L"-shaped stirring member are installed at the end. A number of mutually intersecting inclined buffer frames are arranged on the two side walls of the inner layer of the silo body. By setting a rotating motor and a rotating rod at the top of the silo body in the utility model, an "S" stirring ring and an "L"-shaped stirring member are arranged at the end of the rotating rod, and the rice is stirred during discharging to avoid slow discharging; inclined buffer frames are arranged on the two side walls in the upper and middle parts of the silo body, and the rice can be buffered layer by layer to avoid the problem of high breakage rate; a drying layer is arranged in the silo body to prevent moisture from getting in due to temperature difference inside the silo body. The structure is novel and suitable for rice production enterprises to use.

[0004] However, the above-mentioned vertical silo for storing rice has the following problems in actual use: For rice storage, the most important thing is the airtightness of the silo to ensure that the dry rice will not get damp. However, the existing silos lack an airtightness detection mechanism and cannot detect air leakage points in time. And the existing sealing method at the position of the silo door is a sealing strip, and air leakage points are likely to appear.

[0033] The airtightness detection component 4 includes an air pump 41. The outlet of the air pump 41 is connected to a three-way pipe 42 through a pipeline. The three-way pipe 42 is connected to an exhaust pipe 43. One end of the exhaust pipe 43 penetrates through the silo door 3 and is connected to an exhaust port 44. The exhaust port 44 is arranged inside the silo door 3. A pressure sensor 45 is installed below the exhaust port 44. Air is injected into the silo body 1 to gradually increase the pressure inside the silo body 1 to a certain value. After the pressurization is completed, the pressure change inside the silo body 1 is continuously monitored through the pressure sensor 45. If the pressure drops slightly within a period of time, it indicates that the airtightness of the silo body 1 is good. If the pressure drops rapidly, it indicates that there is a leakage point;

[0034] The airtight component 5 includes an airbag ring 51 embedded in the inner wall of the window 2. The airbag ring 51 is located between the window 2 and the silo door 3. One side of the airbag ring 51 is connected to an air injection interface 52 through a pipeline. The air injection interface 52 is connected to a gas guide pipe 53. The gas guide pipe 53 is connected to the three-way pipe 42. The airbag ring 51 is embedded in the inner wall of the window 2. After the silo door 3 is closed, air is injected into the airbag ring 51 to make the airbag ring 51 closely adhere to the silo door 3. Compared with rubber sealing, this airbag ring 51 sealing method has better airtightness and is not prone to air leakage due to aging.

[0035] Specifically, a feed inlet 6 is installed at the top of the silo body 1. The feed inlet 6 is connected to a feed pipeline 7. A discharge outlet 8 is installed at the bottom of the silo body 1. The silo body 1 is fixedly connected to a support leg 9.

[0036] Furthermore, a handle 10 is fixed on the silo door 3. One side of the silo door 3 is connected to the window 2 through a hinge, and the other side is connected to the window 2 through a movable lock.

[0037] Still further, the air pump 41 is fixed on the outside of the silo door 3 through a fixing frame. The inlet of the air pump 41 is connected to a filtering and adsorption component 11.

[0038] It should be noted that the filtering and adsorption component 11 includes a pipe body 111. Two correspondingly arranged filter meshes 112 are installed inside the pipe body 111. An adsorption filler 113 is filled between the filter meshes 112. The adsorption filler 113 is set as a mixture of a moisture absorbent and activated carbon.

[0039] It should be noted that a partition net 12 is installed inside the exhaust port 44. A protective sleeve ring 13 is fixed outside the pressure sensor 45. A protective partition net 14 is installed on the inner wall of the end of the protective sleeve ring 13.

[0042] Working principle and process: When performing the airtightness detection of the chamber 1, open the control valve 15 on the exhaust pipe 43 and start the air pump 41 of the airtightness detection assembly 4. Then, the outside air passes through the filtration and adsorption assembly 11, and the adsorption filler 113 can adsorb the water vapor and dust in the air, so that the clean air is injected into the chamber 1. Subsequently, the air passes through the air pump 41, the tee pipe 42, and the exhaust pipe 43 and is introduced into the chamber 1 through the exhaust port 44, so that the pressure in the chamber 1 gradually rises to a certain value. After the pressurization is completed, the pressure sensor 45 continuously monitors the pressure change in the chamber 1. If the pressure drops slightly within a period of time, it indicates that the airtightness of the chamber 1 is good; if the pressure drops rapidly, it indicates that there is a leakage point. After the chamber door 3 is closed, open the control valve 15 on the air duct 53 and start the air pump 41, so that the air is injected into the airbag ring 51 through the air duct 53 and the air injection interface 52, causing the airbag ring 51 to expand and closely adhere to the chamber door 3 to ensure the airtightness at the position of the chamber door 3.
