When taking and putting the piece smoke box 33 that is equipped with the piece cigarette in album nitrogen apparatus 3, can dismantle sealing rod 321 from base 31, then promote sealing rod 321 and drive the cover body 32 and separate with base 31, the operating personnel can get and put piece smoke box 33 between the cover body 32 and base 31 this moment, then control sealing rod 321 descends to base 31 on and with base 31 reconnection, album nitrogen apparatus 3 can constantly reuse this moment, need not to destroy the cover body 32, the purpose of material saving has been reached.

Referring to fig. 3, a plate lug 3211 is horizontally and fixedly connected to the sealing rod 321, the plate lug 3211 is located above the base 31, a bolt is threadedly connected to the plate lug 3211, one end of the bolt, which is far away from the bolt cap, penetrates through the plate lug 3211 and then is threadedly connected to the base 31, a plurality of plate lugs 3211 are provided, and the plate lugs 3211 are distributed along the length direction of the sealing rod 321; a first sealing ring and a second sealing ring are arranged between the sealing rod 321 and the bottom surface of the groove, the bottom of the groove on the base 31 is fixedly connected with the first sealing ring, and the lower side of the sealing rod 321 is fixedly connected with the second sealing ring. In the process of the threaded connection of the first bolt and the base 31, the sealing rod 321 can be attached to the bottom surface of the groove more tightly, so that the first sealing ring and the second sealing ring are tightly abutted, and the sealing effect of the nitrogen collecting device 3 is better.

Referring to fig. 3, a supporting rod 311 is disposed on the base 31, one end of the supporting rod 311 is hinged to the base 31 in a universal manner, and the other end is fixedly connected with a hook 3111. After lifting the sealing rod 321 and driving the cover body 32 and separating from the base 31, the supporting rod 311 can be rotated to a proper position, then the sealing rod 321 is abutted to the hook 3111 on the supporting rod 311, an operator can take and place the cigarette box 33 between the cover body 32 and the base 31, the supporting rod 311 can fix the sealing rod 321 relative to the base 31 at the moment, the sealing rod 321 does not need to be manually held by manpower, and the purpose of convenient operation is achieved.

Referring to fig. 3, an air suction pipe 5 is arranged on the nitrogen collecting device 3, one end of the air suction pipe 5 is provided with an air suction fan 51, the other end of the air suction pipe is communicated with the inside of the nitrogen collecting device 3 through a base 31, and an adjusting valve 52 is arranged on the air suction pipe 5. After the tobacco flakes are loaded into the nitrogen collecting equipment 3, the adjusting valve 52 can be opened, then the suction fan 51 is started to exhaust most of air in the nitrogen collecting equipment 3, and then the adjusting valve 52 is closed again, so that the content of oxygen in the nitrogen collecting equipment 3 can be reduced, and the aim of reducing the possibility of deterioration of the stored tobacco flakes is fulfilled.

The implementation principle of the tobacco lamina warehousing system based on the preprocessing technology in the embodiment of the application is as follows: after the tobacco flakes are loaded in the nitrogen collecting equipment, the ozone concentration sensor 43 detects that the ozone content in the pipeline 2 is lower than a preset reference value, so that the controller can automatically control the gas collecting valve 222 to be opened and the exhaust valve 411 to be closed, then the ozone generator 42 is opened to introduce ozone into the pipeline 2, when the ozone concentration is increased to be higher than the preset reference value, the controller can automatically control the gas collecting valve 222 to be closed and the exhaust valve 411 to be opened, at the moment, the ozone is discharged into the air through the exhaust pipe 41 after flowing through the pipeline 2, the ozone generator 42 is controlled to stop working after a period of time, at the moment, the high-concentration ozone still exists in the pipeline 2, the ozone in the pipeline 2 is continuously discharged into the air after being placed for a period of time, and when the ozone concentration sensor 43 detects that the residual ozone concentration in the pipeline 2 is lower than the preset reference value, the controller can automatically open the gas, Closing the exhaust valve 411, then opening the nitrogen making machine 1 to convey nitrogen into the nitrogen collecting equipment 3 through the pipeline 2, finally stopping the nitrogen making machine 1 from working when the concentration of the nitrogen in the nitrogen collecting equipment 3 meets the requirement, and closing the control valve 221; before nitrogen flows through the pipeline 2, the inner wall of the pipeline 2 is sterilized by ozone, meanwhile, odor molecules in the pipeline 2 can be decomposed by ozone, and when nitrogen is filled into the nitrogen collection equipment 3 through the pipeline 2 subsequently, the nitrogen hardly carries mould and peculiar smell, so that the possibility that the tobacco flakes in the nitrogen collection equipment 3 are polluted by the storage environment is low, and the purpose of improving the quality of the tobacco flakes in the tobacco flake storage system is achieved.

The embodiment of the application also discloses a working method of the tobacco lamina storage system based on the preprocessing technology, and the working method comprises the following steps with reference to fig. 2 and 3:

s1, putting the tobacco flake box 33 filled with tobacco flakes into the nitrogen collecting equipment 3, and opening the control valve 221;

s2, opening the adjusting valve 52, opening the suction fan 51, closing the suction fan 51 after a period of time, and closing the adjusting valve 52;

s3, starting the ozone generator 42 to discharge ozone into the pipeline 2, when the ozone concentration sensor 43 detects that the ozone content in the pipeline 2 rises to a certain concentration, the controller automatically controls the air collecting valve 222 to be closed and the exhaust valve 411 to be opened, and the ozone in the pipeline 2 is discharged into the air;

s4, after a period of time, turning off the ozone generator 42, and when the ozone concentration sensor 43 detects that the ozone content in the pipeline 2 is reduced to a certain concentration, the controller will automatically control the gas collection valve 222 to be opened and the exhaust valve 411 to be closed;

s5, opening the nitrogen generator 1 to discharge nitrogen into the pipeline 2, the nitrogen will flow into the nitrogen collecting device 3, closing the nitrogen generator 1 after a while, and closing the control valve 221.

Referring to fig. 3, in the working process of the tobacco lamina warehousing system, the controller can control the gas collection valve 222 and the exhaust valve 411 to automatically act according to the detection signal of the ozone concentration sensor 43, so that the states of the gas collection valve 222 and the exhaust valve 411 can be automatically switched when two processes of ozone sterilization pretreatment and nitrogen gas introduction into the nitrogen collection device 3 are carried out in the pipeline 2, manual switching is carried out after people do not need to know switching conditions, and the control valve 221 only needs to be manually controlled twice, so that the purpose of convenient operation is achieved.
