[0026] The discharge mechanism 4 is connected through the bottom of the storage tank 5. The storage tank 5 can only be discharged through the through pipe 1, and the top of the through pipe 1 is sealed by the sealing mechanism 2. The volatilization of the liquid in the storage tank 5 will accumulate in the top of the storage tank 5, and will not volatilize and leak through the discharge mechanism 4 located at the bottom. The installation of the internal floating roof storage tank sealing assembly can ensure the sealing performance of the storage tank and prevent the liquid or gas in the storage tank from leaking to the external environment. The storage tank is used to store liquid petroleum products, chemicals or other liquid substances. When the liquid level in the storage tank changes, the sealing assembly will not leak, thereby reducing the contact between the liquid and the outside air, reducing volatilization and oxidation, ensuring the quality and safety of the liquid in the storage tank, and improving the safety and operating efficiency of the storage tank.

[0027] like Figure 3 As shown, the utility model provides a technical solution: preferably, the discharging mechanism 4 includes a connecting pipe 44, a motor 43 is fixedly installed on the left end of the connecting pipe 44, a turbine blade 42 is driven and installed on the right end of the motor 43 and located in the connecting pipe 44, a filter screen 41 is fixedly installed on the top of the turbine blade 42 and located at the top of the connecting pipe 44, and the top of the connecting pipe 44 is inserted into the bottom of the storage tank 5.

[0028] In this embodiment, the internal floating roof tank sealing assembly realizes the discharging function through the discharging mechanism 4, and can extract the liquid inside the tank 5 through the through pipe 1. First, the protective mechanism 3 and the sealing mechanism 2 are opened, and the motor 43 drives the turbine blades 42 to rotate to draw the liquid in the tank 5 into the through pipe 1 and the protective mechanism 3.

[0029] like Figure 4 As shown, the utility model provides a technical solution: preferably, the sealing mechanism 2 includes a base column 23, a through groove 24 is opened in the middle of the base column 23, an external pipe 21 is fixedly installed on the top of the base column 23, a sealing plate 22 is hydraulically driven and installed at the lower middle part of the external pipe 21, the protective mechanism 3 is fixedly installed on the top outside of the external pipe 21, the base column 23 is fixedly installed on the top of the through pipe 1, and a threaded pipe 25 is connected to the top of the external pipe 21.

[0030] In this embodiment, when the storage tank 5 is sealed, the external pipe 21 of the internal floating roof storage tank sealing assembly pushes the sealing plate 22 to be located in the through groove 24 to seal and play a sealing role. When the liquid in the storage tank 5 needs to be extracted, the sealing plate 22 is lifted by the external pipe 21 to make the through groove 24 open. The external pipe 21 is connected to the external pipe line through the threaded pipe 25 at the top to drain the liquid in the storage tank 5.

[0031] like Figure 5 As shown, the utility model provides a technical solution: preferably, the protective mechanism 3 includes a ring 33, a rotating shaft 32 is fixedly installed on the left side of the ring 33, a baffle 31 is rotatably installed on the ring 33 through the rotating shaft 32, and the ring 33 is sleeved on the top outer surface of the sealing mechanism 2.

[0032] In this embodiment, when the storage tank 5 is stored, the protection mechanism 3 of the sealing assembly of the internal floating roof storage tank rotates the baffle 31 through the rotating shaft 32, so that the baffle 31 is located on the top of the sealing mechanism 2 to play a protective role and prevent the sealing mechanism 2 used for discharging from being contaminated.

[0033] The following is a detailed description of the working principle of the internal floating roof tank sealing assembly.

[0034] like Figure 1-5As shown, the discharge mechanism 4 is connected through the bottom of the storage tank 5. The storage tank 5 can only be discharged through the through pipe 1, and the top of the through pipe 1 is sealed by the sealing mechanism 2. The volatilization of the liquid in the storage tank 5 will accumulate in the top of the storage tank 5, and will not volatilize and leak through the discharge mechanism 4 located at the bottom. The installed internal floating roof storage tank sealing assembly can ensure the sealing performance of the storage tank and prevent the liquid or gas in the storage tank from leaking to the external environment. The storage tank is used to store liquid petroleum products, chemicals or other liquid substances. When the liquid level in the storage tank changes, the sealing assembly will not leak, thereby reducing the contact between the liquid and the outside air, reducing volatilization and oxidation, ensuring the quality and safety of the liquid in the storage tank, and improving the safety and operation efficiency of the storage tank. The installed internal floating roof storage tank sealing assembly realizes the discharge function through the discharge mechanism 4, and can extract the liquid inside the storage tank 5 through the through pipe 1. First, the protective mechanism 3 and the sealing mechanism 2 are opened, and the motor 43 drives the turbine blades 42 to rotate to draw the liquid in the storage tank 5 into the storage tank 5, and then the liquid is drawn out through the through pipe 1 and the protective mechanism 3. When the storage tank 5 is sealed, the external pipe 21 of the internal floating roof storage tank sealing assembly pushes the sealing plate 22 to be located in the through groove 24 to seal and play a sealing role. When the liquid in the storage tank 5 needs to be extracted, the sealing plate 22 is lifted by the external pipe 21 to make the through groove 24 open. The external pipe 21 is connected to the external pipe line through the top threaded pipe 25 to guide the liquid in the storage tank 5. When the storage tank 5 is stored, the protective mechanism 3 of the internal floating roof storage tank sealing assembly rotates the baffle 31 through the rotating shaft 32, so that the baffle 31 is located at the top of the sealing mechanism 2 to play a protective role and prevent the sealing mechanism 2 used for discharging from being contaminated.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
