Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mixing tank technology, and in particular relates to a mother liquor mixing tank. Background Technology
[0002] Mother liquor mixing tanks are specialized containers used for mixing and preparing mother liquors. They are widely used in chemical, pharmaceutical, food, and bioengineering industries, primarily for mixing various raw materials in specific proportions and achieving uniform dissolution, reaction, or stable storage of materials through heating and stirring. Their core function is to ensure the accuracy of the mother liquor's composition and the stability of its quality, making them a crucial intermediate step in the production process. Because many materials (such as polymers, bioactive components, and crystalline substances) have poor flowability and slow dissolution at low temperatures, or require specific temperatures to activate chemical reactions, and because some processes require materials to be treated within specific temperature zones (such as sterilization or enzymatic hydrolysis), heating is a critical step in ensuring mixing efficiency and product quality. Currently, the commonly used heating method for mother liquor mixing tanks is electric heating, achieved through heating elements within the tank. However, because these heating elements are fixed inside the tank, they can easily lead to excessively high local temperatures or slow overall temperature rise, affecting component stability and hindering the improvement of mother liquor mixing effects and quality. Utility Model Content
[0003] In view of this, the present invention aims to provide a mother liquor mixing tank to solve the problem of poor heating uniformity in existing mother liquor mixing tanks, which affects the stability of the components.

[0005] A mother liquor mixing tank includes a tank body. An inlet pipe and an outlet pipe are located above the tank body, and a discharge pipe and a sludge discharge pipe are located below the tank body. The sludge discharge pipe is vertically mounted on the tank body and coaxially arranged with the tank body. The tank body contains a stirring mechanism for driving liquid flow towards the sludge discharge pipe. A heating mechanism is located around the stirring mechanism within the tank body. An internal flow gap exists between the heating mechanism and the stirring mechanism, and external flow gaps exist between the heating mechanism and the inner wall of the tank body. The internal and external flow gaps are connected. A partition cover is located between the stirring mechanism and the sludge discharge pipe within the tank body to guide liquid flow from the internal to the external flow gaps. A passage gap exists between the partition cover and the inner wall of the tank body to facilitate the passage of sediment. A guide arc plate is located on the side of the partition cover facing the stirring mechanism. Multiple guide arc plates are spaced apart along the circumference of the partition cover, and a sludge discharge gap communicating with the passage gap exists between adjacent guide arc plates.
[0006] Furthermore, the heating mechanism includes a heat-conducting cylinder and heating rods. The heat-conducting cylinder is coaxially arranged with the tank body, an inner flow gap is formed inside the heat-conducting cylinder, and an outer flow gap is formed between the heat-conducting cylinder and the inner wall of the tank body. Multiple heating rods are evenly arranged along the circumference of the heat-conducting cylinder.
[0007] Furthermore, the heat-conducting cylinder is provided with a receiving cavity for accommodating the heating rod, and the heating rod is connected to the inner wall of the receiving cavity through heat-conducting fins.
[0008] Furthermore, the stirring mechanism includes a drive rod and a spiral stirring paddle mounted on the drive rod. The drive rod is rotatably mounted on the tank body, and the tank body is provided with a driver for driving the drive rod to rotate.
[0009] Furthermore, at least two spiral stirring paddles are arranged at intervals along the length of the drive rod.
[0010] Furthermore, the isolation cover is a conical structure, with the smaller diameter end of the isolation cover facing the stirring mechanism and the larger diameter end facing the mud discharge pipe.
[0011] Furthermore, a recess is provided at the bottom of the tank, and the sludge discharge pipe is connected to the recess.
[0012] Furthermore, one end of the drainage arc plate is fixed to the isolation cover, and the other end is fixed to the recess.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] A mother liquor mixing tank, such as Figure 1 and Figure 2As shown, the system includes a tank body 1. A feed pipe 2 and an exhaust pipe 3 are located above the tank body 1, and a discharge pipe 4 and a sludge discharge pipe 5 are located below the tank body 1. The sludge discharge pipe 5 is vertically mounted on the tank body 1 and is coaxial with the tank body 1. Specifically, the tank body 1 can be a conventional mixing tank, and the feed pipe 2, exhaust pipe 3, discharge pipe 4, and sludge discharge pipe 5 are all fixed to the tank body 1. The discharge pipe 4 is positioned above the sludge discharge pipe 5.
[0025] The aforementioned tank 1 is equipped with a stirring mechanism for driving liquid to flow into the sludge discharge pipe 5. A heating mechanism is provided inside the tank 1 at a position corresponding to the stirring mechanism. There is an internal flow gap 11 between the heating mechanism and the stirring mechanism, and there is an external flow gap 17 between the heating mechanism and the inner wall of the tank 1. The internal flow gap 11 and the external flow gap 17 are connected. Inside the tank 1 at a position corresponding to the stirring mechanism and the sludge discharge pipe 5, there is an isolation cover 7 for guiding liquid to flow from the internal flow gap 11 to the external flow gap 17. There is a passage gap 9 between the isolation cover 7 and the inner wall of the tank 1 to facilitate the passage of sediment. A flow guiding arc plate 8 is provided on the side of the isolation cover 7 facing the stirring mechanism. Multiple flow guiding arc plates 8 are arranged at intervals along the circumference of the isolation cover 7. There is a sludge discharge gap between two adjacent flow guiding arc plates 8 that is connected to the passage gap 9.
[0026] For example, the isolation cover 7 can be fixed to the tank 1 by a bracket, and four diversion arc plates 8 are evenly arranged. Each diversion arc plate 8 is fixed to the isolation cover 7 at one end and is set towards the outer flow gap 17 at the other end. By setting the diversion arc plates 8 at intervals, not only can the liquid in the inner flow gap 11 be guided to the outer flow gap 17, realizing the circulation and heating of the liquid in the inner flow gap 11 and the outer flow gap 17, improving the uniformity and heating effect of the liquid heating, but also the sediment can settle to the bottom of the tank 1 through the gap between the diversion arc plates 8 and through the gap 9. The isolation cover 7 can effectively separate the liquid and the sediment, ensuring that the sediment can be discharged from the tank 1 through the sludge discharge pipe 5.
[0027] Preferably, the heating mechanism includes a heat-conducting cylinder 10 and heating rods 15. The heat-conducting cylinder 10 is coaxially arranged with the tank body 1. An inner flow gap 11 is formed inside the heat-conducting cylinder 10, and an outer flow gap 17 is formed between the heat-conducting cylinder 10 and the inner wall of the tank body 1. Multiple heating rods 15 are evenly arranged along the circumference of the heat-conducting cylinder 10. For example, the heating rods 15 can be existing electric heating rods, and their power supply and control methods are existing technologies, which will not be described in detail here.
[0028] In practical applications, the heat-conducting cylinder 10 can also be fixed to the tank 1 by a bracket. The heat-conducting cylinder 10 is provided with a receiving cavity for accommodating the heating rod 15, and the heating rod 15 is connected to the inner wall of the receiving cavity through heat-conducting fins 16. For example, four, five or more heating rods 15 can be evenly arranged inside the receiving cavity of the heat-conducting cylinder 10. Each heating rod 15 is fixed in the receiving cavity of the heat-conducting cylinder 10 through heat-conducting fins 16. By using heat-conducting fins 16 to connect the heating rod 15 and the heat-conducting cylinder 10, the heat of the heating rod 15 can be evenly conducted to all parts of the heat-conducting cylinder 10, avoiding heat concentration. At the same time, the heat-conducting cylinder 10 can also increase the contact area between the heating element and the liquid, thereby improving the efficiency of liquid heating. Combined with the stirring mechanism to drive the liquid flow, it can effectively improve the uniformity of liquid heating in the tank 1.
[0029] Optionally, multiple heat-conducting fins 16 can be spaced apart along the length of the heat-conducting cylinder 10. The heat-conducting fins 16 are provided with mounting holes 19 for mounting the heating rod 15. By providing multiple heat-conducting fins 16, the heat transfer efficiency between the heating rod 15 and the heat-conducting cylinder 10 can be further improved.
[0030] In practical applications, in order to further improve the heat transfer efficiency, the cavity can also be filled with heat transfer oil or heat transfer fluid. The heat transfer fins 16 are provided with through holes 18 to facilitate the passage of oil. The heat transfer cylinder 10 is provided with a liquid filling pipe (not shown in the figure). One end of the liquid filling pipe is fixed on the heat transfer cylinder 10 and communicates with the cavity, while the other end extends out of the tank 1 to facilitate the operator to add or replenish heat transfer oil or heat transfer fluid.
[0031] Preferably, the stirring mechanism includes a drive rod 12 and a spiral stirring paddle 13 mounted on the drive rod 12. The drive rod 12 is rotatably mounted on the tank body 1, and the tank body 1 is provided with a driver 14 for driving the drive rod 12 to rotate. For example, the driver 14 can be a drive motor, and the drive rod 12 can be rotatably mounted on the tank body 1 via bearings. The output end of the drive motor and the drive rod 12 can be connected via a coupling. Those skilled in the art can also select a suitable driver 14 according to actual needs to drive the drive rod 12 to rotate, thereby causing the spiral stirring paddle 13 to rotate. By using the spiral stirring paddle 13, the rotating spiral stirring paddle 13 can not only stir the liquid in the tank body 1, but also drive the liquid in the tank body 1 to flow downwards, achieving circulating flow heating under the guidance of the isolation cover 7 and the guide arc plate 8.
[0032] Preferably, at least two spiral agitators 13 are spaced apart along the length of the drive rod 12. For example, two, three, or more spiral agitators 13 may be spaced apart, and each spiral agitator 13 is mounted and fixed on the drive rod 12. By spaced apart multiple spiral agitators 13, it is not only beneficial to improve the stirring effect of the liquid, but also to increase the flow rate of the liquid.
[0033] Preferably, the isolation cover 7 is a conical structure, with the small diameter end of the isolation cover 7 facing the stirring mechanism and the large diameter end facing the sludge discharge pipe 5. A recessed part 6 is provided below the tank body 1, and the sludge discharge pipe 5 is connected to the recessed part 6. One end of the flow guiding arc plate 8 is fixed on the isolation cover 7, and the other end is fixed on the recessed part 6.
[0034] In practical applications, the conical isolation hood 7 facilitates the falling of sediment, while the recessed portion 6 below the tank 1 promotes the flow and convergence of sediment towards the sludge discharge pipe 5, accelerating the discharge of sediment from the tank 1. The spaced-apart flow-guiding arc plates 8 on the isolation hood 7 provide better guidance for the liquid, forming a U-shaped flow channel below the agitator. This guides the liquid from the inner flow gap 11 to the outer flow gap 17, and ultimately returns it from the outer flow gap 17 above the tank 1, achieving efficient circulating flow and heating of the liquid within the tank 1.
[0035] The mother liquor mixing tank of this utility model, by setting a stirring mechanism and a heating mechanism inside the tank, and utilizing the internal flow gap formed between the heating mechanism and the stirring mechanism, and the external flow gap formed between the heating mechanism and the inner wall of the tank, allows the liquid inside the tank to circulate inside and outside the heating mechanism. This can effectively avoid excessive local temperature of the liquid material, improve the overall heating rate of the liquid material, ensure the stability of the components, and improve the mixing effect and quality of the mother liquor.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
