Description
Technical Field
[0001] The utility model relates to the technical field of medicine processing devices, in particular to a liquid mixing device. Background Art
[0002] In modern industrial and laboratory operations, the mixing of liquids is a critical process step, especially when it comes to chemical reactions, pharmaceuticals, food processing, and biotechnology. Traditional methods usually involve simply introducing two or more different liquids into the same pipe and then flowing into a collection dish. Although this method is intuitive and easy to operate, it lacks an effective dynamic mixing mechanism, resulting in insufficient contact and fusion between liquids, and the mixing effect is often unsatisfactory.
[0003] The limitation of this direct mixing without additional stirring process is that it relies on the fluidity and diffusion ability of the liquid itself to achieve mixing, which is far from enough in many cases. There may be obvious interfaces between the liquid layers, rather than ideal homogeneous solutions, which not only reduces the mixing efficiency, but may also have an adverse effect on the subsequent chemical reaction rate, product quality and the performance of the final product. In order to improve the mixing effect, some manufacturers use blenders for mixing, but mechanical stirring can easily damage the activity of the added ingredients, and the medicinal properties of the prepared solution will be affected to a certain extent. In addition, some pharmaceutical products have multiple components that need to be mixed and packaged on site, while the traditional operation method is usually to mix multiple components and then send them for packaging. The temperature difference or accumulation caused by this method can easily damage certain active ingredients, which will undoubtedly affect the medicinal properties of the product drugs. Summary of the invention
[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a liquid mixing device to solve the problems of poor mixing effect and damage to the activity of added components due to mechanical stirring.
[0005] The technical solution of the utility model includes: comprising a mixing pipe, the mixing pipe conveys at least two liquids, the mixing pipe is connected to a mixer, the mixer comprises an outer pipe and a central axis, the central axis is placed in the outer pipe, and the outer pipe is connected to the mixing pipe to form a connection; a plurality of mixing blocks are fixedly arranged on the central axis along its axial direction, the mixing blocks protrude outwardly along the radial direction of the central axis, a preset spacing is provided between two adjacent mixing blocks, and the installation directions of the two adjacent mixing blocks have a preset angle.
[0006] In a possible design, the cross section of the mixing block is similar to a runway shape, including two arc edges and two straight edges, the two straight edges are parallel to each other, the two arc edges are located at both ends of the straight edges, and the arc edges are convex outward of the mixing block.
[0007] In a possible design, the angle between the installation directions of two adjacent mixing blocks is 90 degrees.
[0008] In a possible design, a cross frame is integrally provided at the outlet of the outer tube, the cross frame spans across the radial ends of the outer tube, and the cross frame also abuts against the end of the central axis to form a limit.
[0009] In a possible design, the inlet side of the mixing pipe is connected to a batching tank and at least one branch pipe, a liquid bag for liquid filling is detachably installed at the inlet of the branch pipe, a first peristaltic pump and a check valve are installed on the branch pipe in the order of liquid flow, and a second peristaltic pump is installed on the mixing pipe downstream of the mixer.
[0010] By adopting the above technical solution, the liquid mixing device provided by the utility model can significantly improve the efficiency and uniformity of liquid mixing. The specific technical effects are as follows:
[0011] 1. Enhance the mixing effect: The mixer, especially the staggered mixing blocks, can produce a strong turbulence effect when the liquid flows through, which can cause the liquid to form complex vortices and folds, greatly increase the collision and diffusion between liquid molecules, and thus improve the mixing efficiency.
[0012] 2. Reduce damage to the activity of ingredients: The 90-degree angle between two adjacent mixing blocks helps to ensure that the liquid can be evenly mixed in all directions. At the same time, the mixing blocks do not move autonomously, avoiding damage to the activity of added ingredients caused by mechanical stirring, thereby obtaining a uniform and active mixture.
[0013] 3. Simplify the mixing process: Use peristaltic pumps to pump liquids, accurately control the infusion rate and flow rate, and make the ratio more accurate, making liquid addition and control more convenient. Solve the problem of multiple components of pharmaceutical products being mixed and packaged immediately, change the traditional method of mixing multiple components and then packaging, which causes the temperature difference or accumulation of different components to damage certain active ingredients, ensure that the product is packaged in time after mixing, thereby improving the quality of the mixture product and increasing the product output.

[0018] like Figure 2 , Figure 3 A liquid mixing device shown includes a mixing pipe 1, in which at least two liquids have been mixed and transported, and a mixer 2 is connected to the mixing pipe 1. The mixer 2 includes an outer tube 21 and a central axis 22. The central axis 22 is placed in the outer tube 21, and the outer tube 21 is connected to the mixing pipe 1 to form a connection. The liquid in the mixing pipe 1 must pass through the outer tube 21; a plurality of mixing blocks 23 are fixedly arranged on the central axis 22 along its axial direction, and at least eight mixing blocks 23 are arranged on the central axis 22. The mixing blocks 23 protrude outward along the radial direction of the central axis 22, and there is a preset spacing between two adjacent mixing blocks 23, and the installation directions of two adjacent mixing blocks 23 have a preset angle β, which means that each mixing block 23 is arranged in a staggered layout. When the liquid flows through the mixer 2, the mixing blocks 23 force the liquid to turn continuously, and the liquid flows in a complex manner in the cavity between the mixing blocks 23 and the outer tube 21, forming a vortex phenomenon. The vortex increases the collision and diffusion between liquid molecules, and multiple flows are superimposed to improve the mixing effect.
[0019] The cross-sectional shape of the mixing block 23 is in the shape of a runway, similar to a rounded rectangle, and includes two arc edges 231 and two straight edges 232, the two straight edges 232 are parallel to each other, the two arc edges 231 are respectively located at the two ends of the straight edges 232, the arc edges 231 are in the shape of outward protrusion of the mixing block 23, and the diagonal center of the cross section of the mixing block 23 is located at the central axis 22. The installation direction of the mixing block 23 is the direction formed by connecting the most protruding position of the arc edge 231 to the diagonal center. The arc edge 231 protruding outward not only increases the contact area with the liquid and the turbulence effect, but also avoids scratching the inner wall of the outer tube 21.
[0020] A preset distance is maintained between two adjacent mixing blocks 23, and the installation direction has an angle β of 90 degrees, ensuring that the liquid can form multi-directional disturbances when passing through each mixing block 23, thereby improving the mixing uniformity.
[0021] A cross frame 211 is integrally provided at the outlet of the outer tube 21, and the cross frame 211 spans across the radial ends of the outer tube 21, and is located at the diameter position of the outer tube 21. The cross frame 211 also abuts against the end of the central axis 22, plays a limiting role, ensures the stability of the central axis 22, and prevents it from detaching from the outer tube 21 when the liquid flows.
[0022] like Figure 1As shown, the inlet side of the mixing pipeline 1 is respectively connected to a batching tank 3 and at least one branch pipeline 4, a liquid bag 5 for liquid filling is detachably installed at the inlet of the branch pipeline 4, a first peristaltic pump 6 and a check valve 7 are installed on the branch pipeline 4 in the order of liquid flow, and a second peristaltic pump 8 is installed on the mixing pipeline 1 in the downstream direction of the mixer 2. In this way, a relatively simple dosing system is formed, in which the dosing tank 3 is used to store the main liquid components and is connected to the mixing pipe 1 through a pipe; the branch pipe 4 is used to connect to other liquid sources outside the dosing tank 3, such as special additives or solvents. There can be multiple branch pipes 4, depending on the required solution. A detachable liquid bag 5 is installed at the inlet of each branch pipe 4. The liquid bag 5 is filled with the solvent required to be mixed into the dosing tank, and the detachable manner is convenient for replacement and cleaning; the first peristaltic pump 6 is used to accurately control the flow rate of the liquid in the branch pipe 4, and the second peristaltic pump 8 is used to promote the mixed liquid to flow further or enter the next processing stage; the check valve 7 is installed after the first peristaltic pump 6 to prevent the liquid from backflowing and ensure that the liquid in the branch pipe 4 can only flow in one direction. During operation, the required liquid is respectively loaded into the liquid bag 5 on the batching tank 3 and the branch pipe 4, the liquid volume of the first peristaltic pump 6 and the second peristaltic pump 8 is set, the first peristaltic pump 6 and the second peristaltic pump 8 are connected through a pedal switch, and the pedal switch is stepped on to start the two peristaltic pumps at the same time, so that the liquid flows from the batching tank 3 and the branch pipe 4 into the mixing pipe 1, and the mixed liquid is pushed into the designated collection container after being mixed and stirred by the mixer 2. In this way, when passing through the mixing block 23 in the mixer 2, the liquid is strongly disturbed, forming a complex flow state, and achieving efficient mixing.
