Description

Technical Field

[0001] This utility model relates to the field of gas-liquid mixing equipment technology, and in particular to a high-efficiency liquid mixing system. Background Technology

[0002] In industries such as chemical, pharmaceutical, food processing, and bio-fermentation, liquid mixing systems typically employ mechanical stirring or gas aeration to achieve material mixing.

[0003] Traditional mechanical stirring devices typically use rotating stirring rods within a mixing tank to shear and circulate the liquid, achieving mixing. However, relying solely on mechanical stirring often fails to ensure sufficient gas dissolution in the liquid, especially when air or other gases need to be introduced for reaction or cultivation. This results in low mass transfer efficiency and problems such as uneven mixing, solution stratification, or insufficient dissolution rate.

[0004] On the other hand, some existing aeration devices typically connect to an external air source via an aeration disc or aeration head, directly introducing gas into the liquid for dispersion. While this type of structure can achieve a certain degree of gas-liquid mixing, it has the following shortcomings: when relying solely on aeration for mixing, the bubble size is large and unevenly distributed, the solubility of the gas in the liquid is limited, making it difficult to achieve a rapid and uniform mixing effect; the gas-liquid mixing process lacks synergy with mechanical stirring, and there is still considerable room for improvement in mixing efficiency and mass transfer efficiency.

[0005] In summary, most existing liquid preparation systems are single-function designs, relying solely on mechanical stirring or gas aeration for mixing, without achieving the synchronous and synergistic effect of mechanical stirring and gas aeration. This leads to problems such as slow mixing speed, low gas dissolution efficiency, and uneven solution distribution, failing to meet the requirements for efficient and uniform liquid preparation. Utility Model Content

[0006] The purpose of this invention is to provide a highly efficient liquid mixing system with significantly higher gas-liquid mixing efficiency and mass transfer efficiency.

[0007] To achieve the above objectives, this utility model provides a high-efficiency liquid preparation system, including a stirring tank, a drive assembly, and an air intake assembly fixed inside the drive assembly;

[0008] Several stirring rods are rotatably installed inside the mixing tank, and several aeration discs are provided at the bottom of its inner cavity.

[0009] The drive assembly includes a sleeve, a drive rod located at the center of the sleeve and capable of horizontal rotation, a swashplate wheel fixedly connected to the drive rod and having an inclined top surface, and a linkage disc located on the top surface of the swashplate wheel and capable of relative sliding.

[0010] The air intake assembly includes a fixed plate seat with several plunger chambers, several plunger rods slidably installed in the plunger chambers, an aeration disc installed on the top of the plunger chambers, and the bottom end of the plunger rods movably connected to the top surface of the linkage disc; the fixed plate seat is also provided with a one-way air intake valve hole communicating with the plunger chambers.

[0011] The drive rod passes through the fixed plate seat and the stirring tank, and is connected to the stirring rod.

[0012] Preferably, the linkage disc has a disc structure, and its surface is provided with a plurality of ball grooves adapted to the plunger rod, and the bottom end of the plunger rod is provided with a ball head structure adapted to the ball grooves.

[0013] Preferably, the surface of the linkage disk is provided with a plurality of supporting frustums, and the ball groove is formed on the top of the supporting frustums.

[0014] Preferably, the top end of the plunger rod is provided with a piston, and the piston is in sliding sealing engagement with the inner wall of the plunger cavity.

[0015] Preferably, the angle between the surface of the linkage disc and the axis of the drive rod is in the range of 25 degrees to 35 degrees.

[0016] Preferably, the angle between the surface of the linkage disc and the axis of the drive rod is 30 degrees.

[0017] Preferably, the one-way intake valve hole is located on the bottom side of the plunger cavity.

[0018] Preferably, the aeration disc is provided with a plurality of vertically penetrating micropores evenly distributed inside.

[0019] Preferably, the fixed plate seat is provided with a plurality of plunger cavities evenly distributed along the axial direction.

[0020] Preferably, the bottom end of the sleeve is provided with a motor connected to the drive rod.

[0021] The high-efficiency liquid mixing system provided by this utility model, through the linkage structure of the swashplate wheel, the linkage plate and the plunger rod, can simultaneously realize the mechanical stirring of the stirring rod and the reciprocating motion of the plunger rod when the drive rod rotates. This drives the air intake component to complete the intake and exhaust of gas, so that the gas is evenly released into the liquid in the mixing tank through the aeration plate, thereby realizing gas-liquid synergistic mixing and significantly improving the liquid mixing efficiency and mixing uniformity.

[0022] In addition, a piston is provided at the top of the plunger rod, which slides and seals with the inner wall of the plunger cavity. Combined with the one-way control of the one-way inlet valve and the one-way outlet valve, it can ensure that the plunger cavity completes a stable intake and exhaust cycle in sequence during the reciprocating motion. At the same time, the numerous micropores distributed inside the aeration disc can continuously and uniformly release gas in the form of microbubbles, avoiding the problems of local gas concentration or large bubbles that are difficult to dissolve, thereby improving the gas-liquid mass transfer efficiency and solution treatment quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The core of this invention is to provide a high-efficiency liquid mixing system with significantly higher gas-liquid mixing efficiency and mass transfer efficiency.

[0034] Please refer to Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of the high-efficiency liquid preparation system provided by the present invention in one specific embodiment; Figure 2 for Figure 1 A schematic diagram of the cross-sectional structure; Figure 3 for Figure 1 Schematic diagram of the internal structure of the middle sleeve; Figure 4 for Figure 1 A schematic diagram of the swashplate wheel, linkage disc, and plunger rod.

[0035] In one specific embodiment, the high-efficiency liquid preparation system provided by this utility model mainly includes a stirring tank 100, a drive assembly 200, and an air intake assembly 300 fixed inside the drive assembly 200.

[0036] The mixing tank 100 has a hollow cylindrical structure, and several stirring rods 110 are rotatably mounted on its inner side. The stirring rods 110 are arranged around the central axis of the mixing tank 100 and are used to mechanically stir the solution inside the tank during system operation. Several aeration discs 120 are also evenly provided at the bottom of the inner cavity of the mixing tank 100, which are used to uniformly release gas into the liquid in the form of microbubbles to achieve gas-liquid mixing.

[0037] The drive assembly 200 includes a sleeve 210, a drive rod 220, a swashplate wheel 230, and a linkage disc 240 slidably mounted on the top surface of the swashplate wheel 230. The swashplate wheel 230 is fixedly sleeved onto the surface of the drive rod 220, which passes through the base plate 310 and the bottom surface of the mixing tank 100 and connects to the lower end of the mixing rod 110. In actual operation, a motor can be mounted at the bottom end of the sleeve 210 and connected to the drive rod 220 to provide rotational driving force.

[0038] The air intake assembly 300 includes a fixed plate seat 310 and a plurality of plunger rods 320. The inner side of the fixed plate seat 310 has a plurality of plunger chambers 311, and a plunger rod 320 is slidably installed in each plunger chamber 311. The bottom end of the plunger rod 320 is movably connected to the surface of the linkage disc 240. The surface of the fixed plate seat 310 has a one-way air intake valve hole 312 and a one-way air exhaust valve hole 313, wherein the one-way air intake valve hole 312 communicates with an external air source, and the one-way air exhaust valve hole 313 located at the top of the plunger chamber 311 communicates with the bottom end of the aeration disc 120. The plunger chambers 311 and the plunger rods 320 can be evenly distributed in the fixed plate seat 310.

[0039] like Figure 3 As shown, the linkage disc 240 has a disc-shaped structure, and its surface can be formed with multiple ball-and-socket grooves adapted to the plunger rod 320. The bottom end of the plunger rod 320 forms a ball head structure and is locked in the ball-and-socket groove, so that the swing of the linkage disc 240 can reliably drive the plunger rod 320 to reciprocate. The top surface of the swashplate wheel 230 has an appropriate tilt angle relative to the central axis of the drive rod 220, for example, 25 degrees to 35 degrees, specifically 30 degrees. When the drive rod 220 rotates, the tilted surface of the swashplate wheel 230 rotates synchronously with the drive rod 220, while the linkage disc 240, which is slidably connected to it, swings up and down (but does not rotate synchronously with the drive rod 220), thereby pushing the plunger rod 320 to reciprocate within the plunger cavity 311.

[0040] During use, a piston is provided at the top of the plunger rod 320, which slides and seals with the inner wall of the plunger cavity 311, enabling the plunger cavity 311 to complete the intake and exhaust processes sequentially: when the plunger rod 320 moves downward, the volume of the plunger cavity 311 increases, and the one-way intake valve orifice 312 opens under the action of external air pressure, allowing external air to enter the plunger cavity 311; when the plunger rod 320 moves upward, the volume of the plunger cavity 311 decreases, the one-way intake valve orifice 312 closes, and the one-way exhaust valve orifice 313 opens under the action of gas pressure, allowing compressed gas to be discharged into the aeration disc 120 through the one-way exhaust valve orifice 313.

[0041] like Figure 4 As shown, the aeration disc 120 has several evenly distributed micropores inside. After the gas enters, it is evenly released into the liquid in the mixing tank 100 through the micropores, forming a large number of microbubbles, thereby achieving aeration and uniform dispersion of the solution. Combined with the mechanical stirring action of the stirring rod 110, this system can achieve thorough gas-liquid mixing in a short time, improving mass transfer efficiency and liquid uniformity.

[0042] In summary, this embodiment, through the cooperation of the swash plate wheel 230, the linkage plate 240, the plunger rod 320 and the aeration plate 120, enables the stirring process and the gas aeration process to be carried out in synergy, thereby significantly improving the liquid preparation efficiency and stirring uniformity.

[0043] Working principle and usage process of this utility model:

[0044] When the system is running, the motor in the drive assembly 200 drives the drive rod 220 to rotate. The drive rod 220 directly drives the stirring rod 110 in the mixing tank 100 to rotate, realizing mechanical stirring of the liquid. On the other hand, the swashplate wheel 230 fixed on the drive rod 220 rotates synchronously. Since the top surface of the swashplate wheel 230 is at a certain angle, it drives the linkage disc 240 slidably mounted on it to oscillate periodically, thereby pushing multiple plunger rods 320 to reciprocate within the plunger cavity 311.

[0045] During the reciprocating motion of the plunger rod 320, its top piston forms a sliding seal with the inner wall of the plunger cavity 311, allowing the plunger cavity 311 to sequentially complete the intake and exhaust processes:

[0046] As the plunger rod 320 moves downward, the volume of the plunger cavity 311 increases, and the one-way air intake valve 312 opens under the action of external air pressure, allowing external air to enter the plunger cavity 311.

[0047] When the plunger rod 320 moves upward, the volume of the plunger cavity 311 decreases, the one-way inlet valve hole 312 closes, and the one-way exhaust valve hole 313 opens under pressure. The compressed gas is discharged into the aeration disc 120 connected to it through the one-way exhaust valve hole 313.

[0048] The aeration disc 120 has several micropores distributed inside. After the gas enters the aeration disc 120 through the one-way exhaust valve hole 313, it is evenly released into the liquid in the mixing tank 100 through the micropores, thereby achieving continuous aeration and dispersion of the liquid. Under the combined action of mechanical stirring and gas aeration, this process enables the solution to mix quickly and uniformly, improving the gas-liquid mass transfer efficiency.

[0049] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0050] The high-efficiency liquid preparation system provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
