The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0024] Please also read Figures 1 to 3 The material circulation reaction tank provided by the utility model is now described. The material circulation reaction tank comprises a tank body 1, a stirring assembly 2, a crushing tank 3 and a reflux circulation pump 4. A feed pipe 11 is provided at the top of the tank body 1, a liquid inlet pipe 12 is provided at the lower side, a liquid discharge pipe 13 is provided at the bottom of the tank body 1, and the reflux circulation pump 4 is connected between the liquid discharge pipe 13 and the tank body 1, and is used to reflux the reaction liquid to the top of the tank body 1. The crushing tank 3 is arranged between the liquid discharge pipe 13 and the reflux circulation pump 4, and is used to crush the solid materials in the reaction liquid and supply the reaction liquid to the reflux circulation pump 4.

[0025] Compared with the prior art, the material circulation reaction tank provided in the present embodiment is a material circulation reaction tank provided in the present embodiment. The solid material and the solution are mixed and reacted under the stirring action of the stirring component 2. Under the action of the reflux circulation pump 4, the reaction liquid containing a small amount of small clumps of solid material enters the crushing tank 3 through the discharge pipe 13. After crushing, the solid material and the solution are fully mixed, which improves the reaction efficiency of the reaction liquid and avoids the problem of insufficient reaction caused by the agglomeration of the solid material itself. The reflux circulation pump 4 refluxes the reaction liquid into the tank body 1, which improves the mixing uniformity of the reaction liquid, further improves the reaction efficiency of the reaction liquid, avoids the waste of raw materials, and improves the quality of the reaction product.

[0026] In this embodiment, the solid material is supplied from the feed pipe 11, and the solution is supplied from the liquid inlet pipe 12, flowing from bottom to top. With the help of the stirring action of the stirring component 2, the two are mixed into a reaction liquid in the tank body 1. Since it is difficult to fully mix the solid and liquid after contact, even under the action of the stirring component 2, some solid materials are still in the solution in the form of clumps and blocks with smaller diameters. Therefore, it is necessary to use the crushing tank 3 to crush the above-mentioned small-diameter clumps or block structures, so that the solid material is fully in contact with the solution to improve the comprehensiveness of the reaction.

[0027] Specifically, a dispersion disk is provided inside the reflux circulation pump 4. When the reflux circulation pump 4 pumps the reaction liquid back, it can also crush a very small amount of agglomerated solid materials that have not been fully crushed in the crushing tank 3, ensuring that there are no agglomerated solid materials in the refluxed reaction liquid.

[0028] In one possible implementation, see Figures 1 to 3 A rotating shaft 31 with a main axis extending in a horizontal direction is provided in the crushing tank 3. A driving motor 32 is provided at one end of the crushing tank 3 away from the discharge pipe 13. The driving motor 32 is connected to the rotating shaft 31 and is used to drive the rotating shaft 31 to rotate. A crushing bent rod 33 is connected to the outer periphery of the rotating shaft 31. A plurality of crushing bent rods 33 are provided at intervals along the axial direction of the rotating shaft 31.

[0029] In this embodiment, the driving motor 32 outside the crushing tank 3 can drive the rotating shaft 31 inside the crushing tank 3 to rotate circumferentially, and the crushing bent rods 33 outside the rotating shaft 31 are used to crush small clumps of solid materials, so that the solid materials and the solution are fully contacted and mixed, and then refluxed to the top of the tank body 1 through the reflux circulation pump 4. This part of the reaction liquid can also further disturb the reaction liquid in the tank body 1, thereby enhancing the contact effect between the solid material and the solution, improving the reaction efficiency of the reaction liquid, and ensuring the full reaction of the reaction liquid.

[0030] In one possible implementation, see Figures 1 to 3 The crushing curved rods 33 are bent and extended toward the outer circumference of the rotating shaft 31, and each group of crushing curved rods 33 includes a plurality of crushing curved rods 33 arranged at intervals along the circumference of the rotating shaft 31. The crushing curved rods 33 are in an S-shaped structure that is bent and extended. In the process of following the circumferential rotation of the rotating shaft 31, the small clumps of solid materials can be crushed and dispersed, which is convenient for enhancing the crushing effect, so that the solid materials are fully mixed in the solution, which helps to improve the efficiency of subsequent reactions and avoid the waste of raw materials.

[0031] For some examples, see Figures 1 to 3A discharge valve 14 is provided at the lower end of the discharge pipe 13. The crushing tank 3 is connected to the discharge pipe 13 through a first pipe body 34. The first pipe body 34 is arranged higher than the discharge valve 14. A circulation opening and closing valve 35 is provided on the first pipe body 34. The opening and closing valve provided on the first pipe body 34 can control the flow of the reaction liquid into the crushing tank 3. When the reaction liquid is completely reacted, the opening and closing valve can be closed and the discharge pipe 13 can be opened to facilitate the full discharge and collection of the reaction liquid after the reaction.

[0032] In one possible implementation, see Figures 1 to 3 The stirring assembly 2 includes a rotary drive member 21, a stirring tube 22 and a stirring arc rod 23. The rotary drive member 21 is arranged on the top of the tank body 1. The rotary drive member 21 has a driving shaft extending downward and penetrating the top wall of the tank body 1. The upper end of the stirring tube 22 is connected to the driving shaft of the rotary drive member 21. The rotary drive member 21 drives the stirring tube 22 and the stirring arc rod 23 to rotate, thereby achieving a disturbing effect on the solid material and the solution, so that the two are fully mixed and the contact efficiency between the two is increased.

[0033] In one possible implementation, see Figures 1 to 3 The liquid outlet end of the reflux circulation pump 4 is connected to a second tube body 36 extending into the tank body 1. The liquid outlet end of the second tube body 36 is connected to the upper part of the stirring tube 22 through a rotary joint 37 to connect the second tube body 36 with the stirring tube 22. A drainage hole 24 is provided on the peripheral wall of the lower part of the stirring tube 22.

[0034] In this embodiment, the second tube body 36 extends into the stirring tank and is connected to the stirring tube 22 through a rotating joint 37. The stirring tube 22 is used to form a reaction liquid delivery channel connected to the second tube body 36, and then the reaction liquid is discharged in an orderly manner with the help of the drainage hole 24 at the bottom of the stirring tube 22. The discharged reaction liquid is used to internally disturb the reaction liquid in the tank body 1, thereby enhancing the reaction effect.

[0035] In one possible implementation, see Figures 1 to 3 The outer end of the stirring arc rod 23 gradually extends upward in an arc shape, and the outer end of the stirring arc rod 23 is connected to a vertical rod 25 extending upward. A reinforcing connecting rod 26 is provided between the vertical rod 25 and the stirring tube 22, and one end of the reinforcing connecting rod 26 is connected to the lower part of the stirring tube 22, and the other end is connected to the middle part of the vertical rod 25.

[0036] In this embodiment, the outer end of the stirring arc rod 23 extends upward in an arc shape to improve the stirring effect. In addition, a vertical rod extending upward is provided at the outer end of the stirring arc rod 23 to further increase the contact area with the reaction liquid and improve the disturbance effect. The provision of the reinforcing rod not only ensures a reliable connection between the vertical rod 25 and the stirring arc rod 23, but also enhances the disturbance effect.

[0037] For some examples, see Figures 1 to 3 The outer periphery of the stirring tube 22 is connected to a radially extending liquid distribution tube 27, and the liquid distribution tube 27 is communicated with the stirring tube 22. A downwardly disposed liquid distribution nozzle 28 is provided at the bottom of the liquid distribution tube 27. There are a plurality of liquid distribution tubes 27, and each liquid distribution tube 27 is provided with a plurality of liquid distribution nozzles 28. The liquid distribution nozzles 28 are spaced apart along the axial direction of the liquid distribution tube 27.

[0038] In this embodiment, the liquid distribution tube 27 can rotate circumferentially with the stirring tube 22 and spray the reaction liquid to the surface of the reaction liquid, which can form an impact effect on the reaction liquid inside the tank body 1, so that the refluxed reaction liquid and the reaction liquid in the tube body are fully mixed, thereby enhancing the reaction effect and improving the reaction efficiency.

[0039] For some examples, see Figures 1 to 3 The outer end of the liquid distribution pipe 27 is also provided with an auxiliary nozzle 29, and the liquid outlet direction of the auxiliary nozzle 29 is arranged toward the outer periphery of the stirring tube 22. The auxiliary nozzle 29 increases the spraying area of ​​the reflux reaction liquid, ensures full coverage above the reaction liquid inside the tank body 1, and improves the reaction efficiency.

[0040] In one possible implementation, see Figures 1 to 3 The lower part of the tank body 1 is also connected to a blowing assembly 5, which includes an air pump 51 and an airflow blowing pipe 52 connected to the air pump 51. The airflow blowing pipe 52 is connected to the interior of the tank body 1, and a one-way valve 53 and a switch valve 54 are provided on the airflow blowing pipe 52.

[0041] In this embodiment, the blowing assembly 5 at the bottom of the tank body 1 uses an air pump 51 to deliver gas to the bottom of the tank body 1 through an airflow blowing pipe 52, and uses the airflow to form a bottom-up tumbling effect, which assists the stirring assembly 2 in enhancing the disturbance effect on the reaction liquid and improves the reaction efficiency of the material. The blowing assembly 5 is selected according to different types of reaction liquids. The blowing assembly 5 can be opened and closed by a switch valve 54, and the one-way valve 53 is used to prevent the reaction liquid from flowing back to the position of the air pump 51, thereby ensuring the safety of use.

[0042] When the above-mentioned material circulation reaction tank is in use, the solid material and the solution are mixed and reacted under the stirring action of the stirring component 2. Under the action of the reflux circulation pump 4, the reaction liquid containing a small amount of small clumps of solid material enters the crushing tank 3 through the discharge pipe 13. After crushing, the solid material and the solution are fully mixed, which improves the reaction efficiency of the reaction liquid and avoids the problem of insufficient reaction caused by the agglomeration of the solid material itself. The reflux circulation pump 4 refluxes the reaction liquid into the tank body 1, which improves the mixing uniformity of the reaction liquid, further improves the reaction efficiency of the reaction liquid, avoids the waste of raw materials, and improves the quality of the reaction product.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
