Example (b):

as shown in fig. 1, the utility model provides a safe stirred tank liquid seal device, including sealed lid 1 and reservoir 2 that is used for storing sealed liquid. The liquid storage tank 2 includes an inner cylinder 21 and an outer cylinder 22 sleeved outside the inner cylinder 21. An annular reservoir 2 is formed between the inner cylinder 21 and the outer cylinder 22. The stirring shaft 3 is inserted into the inner cylinder 21 and can rotate inside the inner cylinder 21. In practice, the reservoir 2 is placed on top of the stirring tank 4. The stirring shaft 3 is inserted into the stirring tank 4 through the inner cylinder 21, and then stirs the materials in the stirring tank 4. Sealing lid 1 fixed connection is in (mixing) shaft 3 for sealing lid 1 can follow (mixing) shaft 3 rotation. The sealing cover 1 is in an inverted bowl shape. The open end of the sealing cover 1 is accommodated in the liquid storage tank 2 and is immersed in the sealing liquid.

The utility model discloses a safe stirred vessel liquid seal device during the use, (mixing) shaft 3 inserts in agitator tank 4 and stirs the material in agitator tank 4. When the stirring shaft 3 is inserted into the stirring tank 4, the opening end of the sealing cover 1 is accommodated in the liquid storage tank 2 and is immersed in the sealing liquid. So that the gas in the stirring tank 4 is sealed by the sealing liquid, and is further well sealed. Simultaneously, sealed lid 1 and (mixing) shaft 3 are connected and follow the (mixing) shaft 3 rotation, avoid rotating between the two to connect and lead to sealed effect not good. The sealing body can be well sealed in rotation in a sealing liquid sealing mode. Further, the sealing pressure in the stirring tank 4 can be adjusted by adjusting the depth of the sealing liquid in the reservoir 2. The deeper the sealing liquid in the reservoir 2, the greater the sealing air pressure. When the air pressure in the stirring tank 4 is too large, the pressure can be automatically relieved through the sealing liquid, and the device is safe and reliable.

In this embodiment, the height of the inner cylinder 21 is greater than the height of the outer cylinder 22. Too high a level of liquid in the reservoir 2 may cause the sealing liquid in the reservoir 2 to climb over the inner drum 21 and enter the interior of the whisking cylinder. In practical use, the sealing cover 1 rotates along with the stirring shaft 3 to cause the sealing liquid to rotate in the liquid storage tank 2, so that the liquid level rises. This may also cause the sealing liquid in the reservoir 2 to climb over the inner drum 21 and enter the inside of the agitating drum.

The height of the inner cylinder 21 is greater than the height of the outer cylinder 22. The sealing liquid in the liquid storage tank 2 can be effectively prevented from entering the stirring cylinder after crossing the inner cylinder 21.

In this embodiment, the inner diameter of the open end of the outer cylinder 22 is smaller than the inner diameter of the lower portion of the outer cylinder 22. This causes the open end of the outer barrel 22 to taper inwardly. When the sealing liquid rotates along with the sealing cover 1, the rising liquid is gradually blocked by the inner wall of the inner turning of the outer cylinder 22, and the sealing liquid is further effectively prevented from flowing out through the outer cylinder 22.

In this embodiment, a sealing ring 11 is disposed between the sealing cover 1 and the stirring shaft 3. This enables an effective seal between the sealing cap 1 and the stirring shaft 3, avoiding gas leakage in the stirring tank 4.

In this embodiment, the distance between the open end of the sealing cover 1 and the bottom of the liquid storage tank 2 is less than one third of the depth of the liquid storage tank 2. Make sealed lid 1 submergence that can be fine in sealed liquid, avoided sealed liquid to rise when rotatory and lead to the opening of sealed lid 1 to break away from sealed liquid, guarantee sealed effect.

In this embodiment, the inner wall of the outer cylinder 22 is provided with a plurality of water blocking columns 221. The plurality of water blocking columns 221 extend in the direction of the inner cylinder 21. When the sealing liquid rotates along with the sealing rod, the water retaining column 221 can block the sealing liquid to reduce the speed of the sealing liquid, so that the sealing effect is not good due to the fact that the rotating speed is too fast.

In this embodiment, the opening end of the seal cap 1 is in the shape of a knife edge. This reduces the contact area between the seal cap 1 and the sealing liquid, and further reduces the rotation speed of the sealing liquid, thereby preventing leakage.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
