The top of tank cover 2 is threadedly connected with multiple screws 3, and the bottom of multiple screws 3 is threadedly connected at the top of tank body 1, to ensure the sealing between tank cover 2 and tank body 1, to prevent chemical leakage.

[0032] The top of tank cover 2 is fixedly connected with constant pressure cylinder 4, and constant pressure cylinder 4 is used to maintain stable pressure in tank, and the outside of constant pressure cylinder 4 is fixedly connected with pressure gauge 11, which can display the pressure condition in tank in real time, so as to be monitored and adjusted by operator. The inner wall of the top of constant pressure cylinder 4 is fixedly connected with spring 5, and the other end of spring 5 is fixedly connected with pressing plate 6, and the outer wall of pressing plate 6 is slidingly connected to the inner wall of constant pressure cylinder 4, so that pressing plate 6 can move up and down inside constant pressure cylinder 4, so as to automatically adjust pressure according to the change of pressure in tank. The bottom of constant pressure cylinder 4 is fixedly connected with gas delivery pipe 7, and gas delivery pipe 7 is used to deliver gas, so as to realize the gas circulation between constant pressure device and storage tank device. The inner wall of gas delivery pipe 7 is slidingly connected with sliding ring 8, and the design of sliding ring 8 makes the whole one-way valve device movable to compress the gas in pipe. The top of sliding ring 8 is rotatably connected with rotating plate 9, and the inner wall radius of sliding ring 8 is smaller than the radius of rotating plate 9, so that rotating plate 9 can rotate 90 degrees inside gas delivery pipe 7, while ensuring that gas can only flow in one direction. The bottom of gas delivery pipe 7 is fixedly connected with filter head 10, and the function of filter head 10 is to filter out impurities and chemical substances in the gas entering gas delivery pipe 7, to prevent the internal blockage of gas delivery pipe 7.

[0033] The outer wall of tank body 1 is fixedly connected with fixing ring 12, and the bottom of fixing ring 12 is fixedly connected with multiple support frames 13, and fixing ring 12 and support frame 13 are used to support the whole storage tank device, and make the storage tank device stable during operation. The side of multiple support frames 13 is fixedly connected with bottom plate 14, and the top of bottom plate 14 is fixedly connected with working assembly for self-circulation stirring during stirring process of storage tank device, and bottom plate 14 is used to carry working assembly.

[0034] Referring to Figures 1 to 3, the working assembly includes a motor 15, which is the power source of the entire mechanical stirring tank device. The bottom of the motor 15 is fixedly connected to the top of the base plate 14 to ensure the stability and safety of the motor 15. The driving end of the motor 15 is fixedly connected to a transmission column 16, which is used to transmit the power of the motor 15 to the stirring device inside the tank body 1. The outer wall of the transmission column 16 is rotatably connected to the bottom of the tank body 1. The outer wall of the transmission column 16 is fixedly connected to a sleeve 17, and the outer wall of the sleeve 17 is fixedly connected to a plurality of stirring bars 18, which are key components for achieving material mixing. The other ends of the plurality of stirring bars 18 are in contact with the inner wall of the tank body 1 to ensure that the stirring bars 18 can fully contact the material in the tank during rotation to achieve uniform mixing.

[0035] The outer wall of the transmission column 16 is fixedly connected to a sleeve 21, and the outer wall of the sleeve 219 is fixedly connected to a screw feeder 20. The screw feeder 20 will rotate with the transmission column 16, thereby transporting the material from the bottom of the tank body 1 to the top of the tank body 1 for circulation, so as to achieve the purpose of sufficient mixing. The bottom of the tank body 1 is fixedly connected to a discharge pipe 21, and the bottom of the discharge pipe 21 is provided with a sealing port, which can remain closed when discharge is not required to prevent material leakage.

[0036] Working principle: When the mechanical stirring tank device is in operation, the motor 15 is turned on, and the operation of the motor 15 drives the transmission column 16 to rotate. When the transmission column 16 rotates, it drives the sleeve 17 and the sleeve 2 19 to rotate. When the sleeve 17 rotates, it drives the stirring bar 18 to rotate, thereby stirring and mixing the material inside the tank body 1. At the same time, the rotation of the sleeve 2 19 drives the screw feeder 20 to rotate, thereby continuously transporting the material at the bottom to the top of the tank body 1 and then falling, thereby realizing self-circulating stirring of the material inside the tank body 1, thereby improving the stirring and mixing effect.

[0037] During the mixing process, some chemicals react to increase or decrease the pressure of the gas inside the tank 1. When the pressure of the gas inside the tank 1 increases, the gas enters the gas pipe 7 through the filter head 10, pushes the rotating plate 9 to rotate 90 degrees, and enters the constant pressure cylinder 4, so that the pressure acts on the pressing plate 6, the pressing plate 6 moves upward, the spring 5 is compressed, and the air above the pressing plate 6 is discharged from the constant pressure cylinder 4, so as to balance the pressure inside the tank 1. When the pressure of the gas inside the tank 1 decreases, the air above the pressing plate 6 is sucked from the outside, so as to drive the spring 5 to stretch, drive the pressing plate 6 to move downward, and when the pressing plate 6 moves downward, the rotating plate 9 is closed due to the direction of the gas from outside to inside, so as to drive the rotating plate 9 and the sliding ring 8 to move downward, further compress the gas inside the tank 1, and then increase the pressure inside the tank 1 to the set value. In this way, the gas inside the tank 1 is treated with constant pressure under the premise of ensuring that the chemicals inside the tank 1 do not leak.
