[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model provides the following technical solution: As attached Figure 1-2As shown, this utility model discloses a sealed mixing tank, mainly including a tank body 1, a head 2, and a support leg 3. The head 2 is disposed above the tank body 1, and the lower end of the head 2 is connected to the upper end of the tank body 1. The support leg 3 is disposed on the side of the tank body 1 away from the head 2. A sealing connection assembly 4 is provided between the head 2 and the tank body 1. The sealing connection assembly 4 fixes the head 2 on the tank body 1. The sealing connection assembly 4 includes a sealing assembly 5 and a connecting assembly 6. The connecting assembly 6 includes an upper fixing ring 7 and a lower fixing ring 8. The upper fixing ring 7 is fixedly connected to the head 2, and the lower fixing ring 8 is fixedly connected to the tank body 1. The sealing assembly 5 is disposed between the upper fixing ring 7 and the lower fixing ring 8. The sealing assembly 5 includes a sealing element 9 and a sealing ring 10. The sealing element 9 is disposed between the upper fixing ring 7 and the lower fixing ring 8. Specifically, both the upper fixing ring 7 and the lower fixing ring 8 have sealing ring grooves 11, which cooperate to form a sealing cavity 12, and the sealing element 9 is disposed within the sealing cavity 12. Sealing grooves 13 are provided on both the upper and lower sides of the sealing element 9, and the sealing ring 10 is disposed within the sealing grooves 13. In this embodiment, the connecting assembly 6 serves to tightly connect the upper fixing ring 7 and the lower fixing ring 8 together, forming a stable structure to ensure that the sealing assembly 5 can be stably disposed between the tank body 1 and the end cap 2. Simultaneously, the design of the connecting assembly 6 also considers ease of disassembly and installation, allowing for easy operation when maintenance or replacement of the sealing assembly 5 is required. Furthermore, the connecting assembly 6, through the arrangement of the upper and lower fixing rings, ensures a stable connection effect during long-term use, avoiding sealing failure due to loosening or damage. The sealing assembly 5 ensures a good seal at the connection between the end cap 2 and the tank body 1, preventing material leakage within the tank body 1. The sealing assembly 5, through the arrangement of the sealing element 9 and the sealing ring 10, and the cooperation of the upper fixing ring 7 and the lower fixing ring 8, forms a tight sealing structure. The sealing element 9 has an I-shaped cross-section, with its upper and lower sealing grooves 13 corresponding to the sealing ring grooves 11 of the upper fixing ring 7 and the lower fixing ring 8, respectively. The sealing ring 10 is disposed within the sealing grooves 13, thus achieving a multiple sealing effect. This design not only improves the reliability of the seal but also effectively prevents material leakage from the connection under high pressure or high temperature conditions.

[0020] Furthermore, the sealing element 9 has an I-shaped cross-section, with its upper and lower ends extending into the sealing ring grooves 11 of the upper fixing ring 7 and the lower fixing ring 8 for connection. The sealing ring 10 is disposed between the sealing element 9 and the connecting assembly 6. In this embodiment, the function of the sealing element 9 is to provide a stable sealing surface, ensuring that the sealing ring 10 can fit tightly between the upper fixing ring 7 and the lower fixing ring 8, thereby preventing material leakage. At the same time, the I-shaped structure design of the sealing element 9 also increases its structural strength, enabling it to withstand greater pressure and improving the durability of the sealing assembly 5. In addition, the fit design between the sealing element 9 and the sealing ring 10 further enhances the sealing effect, ensuring the safe storage of materials in the tank 1.

[0021] Furthermore, the upper fixing ring 7 and the lower fixing ring 8 are tightly fitted together. The side wall of the upper fixing ring 7 near the lower fixing ring 8 is provided with several first positioning strips 14 and first limiting ring grooves 15. The lower fixing ring 8 is provided with second limiting ring grooves 16 and second positioning strips 17 at positions corresponding to the first positioning strips 14 and first limiting ring grooves 15, respectively. The first positioning strips 14 on the upper fixing ring 7 extend into the second limiting ring grooves 16, and the second positioning strips 17 on the lower fixing ring 8 extend into the first limiting ring grooves 15 for connection. In this embodiment, the first positioning strips 14 and first limiting ring grooves 15, together with the second positioning strips and second limiting ring grooves, ensure accurate alignment of the upper fixing ring 7 and the lower fixing ring 8 during connection, avoiding misalignment or displacement leading to poor sealing. In addition, the design of the positioning strips and limiting ring grooves also increases the stability of the connecting assembly 6, enabling it to withstand greater external forces and pressures, ensuring the reliability and durability of the sealing assembly 5 during long-term use. Meanwhile, the design of the positioning strip and the limiting ring groove, together with the sealing component 5, can effectively prevent material leakage from the connection under high pressure or high temperature conditions, further improving the sealing performance.

[0022] Furthermore, a fastener is provided between the upper fixing ring 7 and the lower fixing ring 8. The upper fixing ring 7 has several fixing holes 18, and the lower fixing ring 8 has connecting holes 19 corresponding to the fixing holes 18. The fastener passes through the fixing holes 18 and the connecting holes 19 to fix the upper fixing ring 7 and the lower fixing ring 8. In this embodiment, the fastener tightly connects the upper fixing ring 7 and the lower fixing ring 8 together through the connecting holes 19 and the fixing holes 18, forming a stable overall structure. This fixing method not only enhances the stability of the connecting assembly 6 but also improves the sealing performance of the sealing assembly 5. The design of the fastener ensures a stable fixing effect during long-term use, avoiding sealing failure due to loosening or damage. At the same time, the installation and removal of the fastener are relatively convenient, facilitating operation when maintenance or replacement of the sealing assembly 5 is required. In this embodiment, the fastener can be a bolt or screw, or other fastening connector. (Fastener not shown in the diagram) Furthermore, a gasket 20 is provided between the upper fixing ring 7 and the lower fixing ring 8. The gasket 20 has an annular hollow structure and is positioned between the fixing member and the positioning strip 14. In this embodiment, the gasket 20 serves to increase the sealing between the upper fixing ring 7 and the lower fixing ring 8, preventing material leakage from the gap between the positioning strip and the limiting ring groove. The annular hollow structure design of the gasket 20 not only provides an additional sealing layer but also effectively disperses pressure, reducing the pressure exerted by the fixing member on the upper fixing ring 7 and the lower fixing ring 8. In addition, the gasket 20 also increases the buffering performance of the connecting assembly 6, making the entire sealed connecting assembly 4 more stable when subjected to external forces, further improving the durability and safety of the mixing tank.

[0023] Furthermore, the sealing element 9 is interference-fitted with the upper fixing ring 7 and the lower fixing ring 8. In this embodiment, the sealing element 9 is interference-fitted with both the upper and lower sides, which ensures that the sealing element 9 can fit tightly between the upper fixing ring 7 and the lower fixing ring 8, thereby forming a continuous, leak-free sealing structure. This interference-fit design not only improves the reliability of the seal but also effectively prevents material from leaking out from the tiny gaps between the sealing element 9 and the mating surfaces under high pressure or high temperature conditions. At the same time, the interference fit also enhances the overall structural strength of the sealing assembly 5, enabling it to withstand greater external forces and pressures, ensuring the stability and durability of the sealing assembly 5 during long-term use. In addition, the interference fit design simplifies the installation process of the sealing assembly 5 and improves work efficiency, because once the sealing element 9 is correctly installed between the upper fixing ring 7 and the lower fixing ring 8, it will automatically fit tightly against the mating surfaces due to the interference fit, without the need for additional fixing or adjustment.

[0024] Furthermore, both the sealing element 9 and the sealing ring 10 are made of elastic rubber. In this embodiment, the material chosen for the sealing element 9 and the sealing ring 10 is elastic rubber. This material has good elasticity and corrosion resistance, enabling it to adapt to various harsh working environments and maintain stable sealing performance. Simultaneously, the elastic rubber material can effectively absorb and disperse pressure, protecting the sealing assembly 5 from direct impact from material pressure, thereby extending the service life of the entire sealing connection assembly 4. In addition, the elastic rubber material also has good wear resistance and anti-aging properties, maintaining a stable sealing effect during long-term use and avoiding sealing failure due to material aging. Therefore, choosing elastic rubber as the material for the sealing element 9 and the sealing ring 10 is one of the key factors in ensuring the stable and reliable sealing performance of the mixing tank.
