DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Referring to Figures 1-7 An extraction rectification toluene mixed liquid production storage tank, including tank body 1, feed inlet 2, discharge outlet 3, stirring assembly 4 and vibration assembly 8.

[0032] The tank body 1 is cylindrical, which is beneficial to the uniform distribution and storage of the liquid in the tank. The top of the tank body 1 is relatively flat, providing a stable platform for the installation of components such as the feed inlet 2 and the driving motor 6. The bottom is slightly concave compared to the top, which helps the liquid to collect at the center of the tank body 1 bottom, facilitating the discharge operation. The tank body 1 is made of corrosion-resistant metal material, such as stainless steel, to adapt to the chemical properties of the toluene mixed liquid, prevent the tank body 1 from being corroded, and ensure the service life of the storage tank. The feed inlet 2 is provided on the top of the tank body 1 in a funnel-shaped structure, with the large end facing upwards and the small end directly communicating with the inside of the tank body 1. This design allows the toluene mixed liquid to flow more smoothly into the tank body 1, reducing the splashing and spilling of the liquid. The funnel-shaped structure also provides a certain buffering effect for the liquid, preventing it from directly impacting other components in the tank. The feed inlet 2 is fixedly provided with a guide plate 14 inside. The guide plate 14 is installed on the inner wall of the feed inlet 2. The guide plate 14 guides the toluene mixed liquid to flow uniformly into the tank body 1, preventing the liquid from concentrating in a certain area. The guide plate 14 allows the liquid to flow smoothly along the surface of the guide plate 14 into the tank body 1, promoting the preliminary mixing of the liquid in the tank. The discharge outlet 3 is provided at the bottom of the tank body 1, near the edge of the tank body 1. This position design facilitates the complete discharge of the toluene mixed liquid in the tank, avoiding liquid residue.

[0033] The stirring assembly 4 is installed in the tank body 1, and the stirring assembly 4 comprises a stirring shaft 5 which penetrates through the center of the top of the tank body 1 and is connected with the driving motor 6 above the top of the tank body 1. The stirring shaft 5 is made of high-strength metal material such as alloy steel, and the diameter and length of the stirring shaft 5 can bear the weight of the stirring blades 7 and the torque generated during rotation. The stirring shaft 5 is installed with multiple layers of stirring blades 7, and the shape and size of each layer of stirring blades 7 are different from each other. The stirring blades 7 of different shapes and sizes can generate different flow fields during stirring, thereby more effectively promoting the mixing of the toluene mixture. For example, the upper stirring blades 7 are designed as wide paddles to generate a larger stirring range to form macroscopic flow of the liquid in the tank, and the lower stirring blades 7 are designed as spiral or turbine type to generate strong shear force to promote microscopic mixing of the liquid. The stirring blades 7 are made of corrosion-resistant metal material or engineering plastic to adapt to the chemical properties of the toluene mixture. The vibration assembly 8 is installed at the bottom of the tank body 1, and the vibration assembly 8 is used to vibrate the tank body 1 during storage to prevent the solid particles or impurities in the toluene mixture from settling at the bottom of the tank body 1, thereby maintaining the uniformity of the mixture.

[0034] Firstly, referring to Figure 5 In the embodiment, a plurality of partitions 9 are further included, which are installed inside the tank body 1 in parallel and horizontally. The partitions are made of corrosion-resistant metal material or engineering plastic and are fixed in the tank body 1 by welding or other means. The horizontal and parallel installation divides the space inside the tank body 1 into a plurality of independent storage chambers 10. Each chamber is relatively independent and can store toluene mixtures in different states or stages as needed. The storage chambers 10 are fixedly provided with communication pipes 11 for connection. The communication pipes 11 are also made of corrosion-resistant material. Valves 12 installed on the communication pipes 11 are used to control the flow of the mixture between different chambers. When it is needed to mix the liquids in different chambers, the corresponding valves 12 can be opened to make the liquids flow through the communication pipes 11. When it is needed to keep the chambers independent, the valves 12 can be closed. This design increases the flexibility of the storage tank and can meet the needs of different production processes for storage and adjustment of toluene mixtures.

[0035] Then, referring to Figure 4In this embodiment, the plurality of baffles 13 fixedly arranged inside the tank body 1 are all arc-shaped and uniformly distributed along the edges of the stirring blades 7. The baffles 13 are made of corrosion-resistant metal plates or plastics and are accurately processed into arc shapes. The design of uniformly distributing the baffles 13 along the edges of the stirring blades 7 can interfere with the flow of the liquid when the stirring blades 7 rotate. When the stirring blades 7 push the liquid to flow, the baffles 13 can change the flow direction and speed of the liquid, so that the liquid forms a more complex flow field. This complex flow field helps to improve the mixing effect of the liquid and promotes the uniform distribution of each component in the toluene mixed liquid. At the same time, it can also reduce the vortex and dead angle that may occur in the stirring process of the liquid, further improving the stirring efficiency and mixing quality.

[0036] Secondly, referring to Figure 2 In this embodiment, the discharge pump 15 installed at the discharge port 3 has its inlet fixedly arranged with the discharge port 3. The discharge pump 15 is a corrosion-resistant centrifugal pump or a positive displacement pump, which is selected according to the characteristics of the toluene mixed liquid and the discharge requirements. The discharge pump 15 can provide sufficient pressure to transport the toluene mixed liquid in the tank to the external equipment, ensuring smooth discharge process. The outlet of the discharge pump 15 is connected to the external equipment through the discharge pipeline 16. The discharge pipeline 16 is made of corrosion-resistant pipeline materials, such as stainless steel pipes or polytetrafluoroethylene pipes. The flow regulating valve 17 fixedly arranged on the discharge pipeline 16 is used to control the flow size of the discharge. The operator can accurately control the discharge speed of the toluene mixed liquid by adjusting the flow regulating valve 17 according to the receiving capacity of the external equipment and the requirements of the production process, so as to ensure the stability and continuity of the production process.

[0037] Finally, referring to Figure 6 and Figure 7In the embodiment, the vibration assembly 8 comprises a mounting plate 18 which is detachably arranged at the bottom of the tank body 1, is made of metal plate, is connected with the bottom of the tank body 1 by bolt connection or other detachable manner, is convenient for installation and maintenance, the springs 19 which are uniformly and fixedly arranged on the mounting plate 18 are made of high-quality spring 19 steel, have a proper elastic coefficient, the vibration plates 20 which are fixedly arranged between the top portions of the springs 19 are provided with a proper elastic coefficient, the springs 19 play a role of buffering and transmitting vibration in the vibration process, so that the vibration plates 20 can generate stable vibration effect, the motor 21 which is fixedly arranged on the mounting plate 18 provides power for the vibration assembly 8, the rotating rod 22 which is fixedly arranged on the output shaft of the motor 21 is adapted with the sliding groove 23 which is arranged on the mounting plate 18, one end of the rotating rod 22 is attached to the vibration plate 20, the other end is adapted with the sliding groove 23 which is arranged on the mounting plate 18, when the motor 21 rotates, the rotating rod 22 rotates in the sliding groove 23, the attached surface of the rotating rod 22 and the vibration plate 20 will push the vibration plate 20 to generate vibration, by controlling the rotating speed of the motor 21, the vibration frequency and amplitude of the vibration plate 20 can be adjusted, the inclined drainage plate 24 which is fixedly arranged at the top of the vibration plate 20 is close to the discharge port 3 at the low end, the inclined direction is towards the discharge port 3, the drainage plate 24 is made of corrosion-resistant metal or plastic, the inclined design thereof can guide the toluene mixed solution at the tank bottom to flow to the discharge port 3 in the vibration process, prevent solid particles or impurities from depositing at the tank bottom, at the same time, can also accelerate the discharging process of the liquid, ensure that the liquid in the tank can be discharged more thoroughly.
