If other equipment uses the mixing device 100 provided by the present application, it should also fall within the scope of protection of the present application. For example, the mixing device 100 of the embodiment of the present application can also be used in the preparation of liquid mixing in the coating industry, the cosmetics industry, etc., and is particularly suitable for mixing liquids with a certain viscosity.
[0057] The mixing device 100 may further include a cover 40 disposed at the feed inlet 11 of the tank body 10 to cover the tank body 10. A discharge port is disposed at the bottom of the tank body 10 (ie, a side away from the feed inlet 11) to discharge the mixed materials.
[0058] The first driving member 20 can be a motor, a cylinder or a hydraulic cylinder, etc., and the driving member is used to drive the stirring shaft 31 to rotate.

[0059] One, two or more first stirring blades 34 may be respectively provided on the first fixed rod 32 and the second fixed rod 33. The first stirring blade 34 may be perpendicular to the first fixed rod 32 and the second fixed rod 33 and extend toward the feeding port 11.

[0060] In the above scheme, by cross-arranging the first fixed rod 32 and the second fixed rod 33 connected to the stirring shaft 31, and providing the first stirring blade 34 on both the first fixed rod 32 and the second fixed rod 33, the stirring uniformity of the liquid mixing can be improved, especially for mixed liquids with a certain viscosity, a more uniform mixed liquid can be obtained.
[0061] In some embodiments, the stirring assembly 30 further includes a second stirring blade 35 . The first fixing rod 32 and / or the second fixing rod 33 are both provided with the second stirring blade 35 . The second stirring blade 35 is located between the stirring shaft 31 and the first stirring blade 34 .
[0062] The second stirring blade 35 can be perpendicular to the first fixed rod 32 and the second fixed rod 33 and extend in the direction of the feed port 11.

The second stirring blade 35 can have the same shape as the first stirring blade 34, or they can be different.

[0063] In the above solution, the first stirring blade 34 and the second stirring blade 35 can stir the liquid at different positions, thereby increasing the range of the stirring depth of the stirring component 30 and further improving the uniformity of stirring.

[0065] The second stirring blade 35 is located in the middle between the first stirring blade 34 and the stirring shaft 31 .
[0066] In the above solution, by arranging the second stirring blade 35 at the middle position, the stirring uniformity can be further improved.
[0067] In some embodiments, the first stirring blade 34 is disposed at an end of the first fixing rod 32 and the second fixing rod 33 away from the stirring shaft 31 .
[0068] The first stirring blade 34 is located at the ends of the first fixing rod 32 and the second fixing rod 33 .
[0069] In the above solution, the first stirring blade 34 is arranged at the ends of the first fixing rod 32 and the second fixing rod 33, so that the first stirring blade 34 can stir the liquid near the edge of the tank body 10, further improving the uniformity of stirring.
[0070] In some embodiments, two first stirring blades 34 are disposed on the first fixing rod 32 and the second fixing rod 33 , and the two first stirring blades 34 are respectively located on both sides of the stirring shaft 31 .

[0077] In the above solution, the two second stirring blades 35 are connected by the fourth fixing rod 37 , and the fourth fixing rod 37 is fixed to the stirring shaft 31 , so that the stability of the second fixing rod 33 can be increased.
[0078] Figure 3 Schematic diagram of the structure of the mixing device of other embodiments of the present application; Figure 4 This is a top view of a mixing device according to some embodiments of the present application.
[0079] Please refer to Figure 3 and Figure 4 In some embodiments, the mixing device 100 further includes a plurality of feeding pipes 50 , and ends of the feeding pipes 50 are inserted into the feeding port 11 of the tank body 10 .
[0080] The feed pipe 50 can be used to input different liquids, and can also be used to input water into the tank body 10. The number of the feed pipes 50 can be set according to requirements.
[0081] In the above scheme, raw materials are simultaneously fed into the tank body 10 through a plurality of feed pipes 50, which can improve the preparation efficiency and avoid cross contamination.
[0082] In some embodiments, a flow meter 51 for monitoring the feed flow rate is disposed on the feed pipe 50 .
[0083] The flowmeter 51 can be an electromagnetic flowmeter 51, a turbine flowmeter 51, a vortex flowmeter 51 and a mass flowmeter 51. For example, the electromagnetic flowmeter 51 is based on Faraday's law of electromagnetic induction. When a conductive liquid flows through a magnetic field, an induced electromotive force is generated in a direction perpendicular to the direction of flow of the magnetic field, and its magnitude is proportional to the flow rate of the liquid. The principle of the turbine flowmeter 51 is that the fluid impacts the turbine blades to rotate the turbine, and the rotation speed of the turbine is proportional to the flow rate of the fluid. The flow rate is determined by detecting the rotation speed of the turbine. The principle of the vortex flowmeter 51 is to place a non-streamlined object (such as a vortex generator) in the fluid. When the fluid flows through, vortices are alternately generated on both sides of the object, and the frequency of the vortex is proportional to the flow rate. The mass flowmeter 51 can directly measure the mass flow rate of the fluid, and it uses the principle of Coriolis force. When the fluid flows in a vibrating tube, a Coriolis force proportional to the mass flow rate is generated, and the mass flow rate is determined by measuring this force.
[0084] In the mixing device 100, different raw materials need to be mixed in a certain ratio to obtain the desired product. The feed flow rate of each raw material can be accurately measured by the flow meter 51, so as to accurately control the ratio between them. The flow meter 51 can monitor the feed flow rate in real time, and when the flow rate is abnormal (such as a sudden increase or decrease), the problem can be discovered in time. The flow data recorded by the flow meter 51 can be used for recording and subsequent analysis of the production process. By analyzing the historical flow data, the mixing process can be optimized, such as adjusting the feed rate to improve production efficiency or improve product quality.
[0085] In the above scheme, the feed amount is monitored by the flow meter 51, so that the feed speed can be controlled, thereby improving the mixing uniformity of the raw materials.
[0086] Figure 5 It is a schematic structural diagram of a mixing device according to some other embodiments of the present application.
[0087] like Figure 5 As shown, in some embodiments, the mixing device 100 also includes a circulation component 60, the circulation component 60 includes a second driving member 61 and a circulation pipe 62, and the two ends of the circulation pipe 62 are respectively provided with a circulation outlet 621 and a circulation feed port 622, the circulation outlet 621 is connected to the bottom of the tank body 10, and the circulation feed port 622 is inserted into the interior of the tank body 10 through the feed port 11.
[0088] The second driving member 61 can be a motor, a hydraulic cylinder, a pneumatic cylinder, etc.
[0089] The second driving member 61 provides power to make the material in the tank body 10 flow out from the circulation outlet 621, pass through the circulation pipe 62, and then re-enter the tank body 10 from the circulation inlet 622. For example, the second driving member 61 is a circulation pump. When it is started, a certain pressure difference will be formed in the circulation pipe 62, which promotes the material to flow in this closed circulation loop.
[0090] The material flows out from the circulating discharge port 621 at the bottom of the tank body 10, which ensures that the material components settled at the bottom can be extracted to avoid local component accumulation during the mixing process. Then the material is transported through the circulation pipe 62 and enters the tank body 10 again through the circulating feed port 622 inserted into the tank body 10, thereby realizing the circulating mixing of the material.
[0091] In the above scheme, the liquid at the circulation outlet 621 is transported to the circulation feed inlet 622 by the second driving member 61, and then returned to the tank body 10 for stirring again, so that the insufficiently stirred mixed liquid can be further stirred, thereby improving the overall uniformity of the mixed liquid.
[0092] Figure 6 It is a schematic structural diagram of a mixing device in some other embodiments of the present application.
[0093] like Figure 6 As shown, in some embodiments, a visual window 71 is opened on the tank body 10 , and the mixing device 100 further includes a monitoring probe 72 disposed on the tank body 10 , and the monitoring probe 72 is disposed toward the visual window 71 .
[0094] The visual window 71 allows the operator to directly see the mixing of the materials in the tank body 10. For example, the flow state of the material can be observed, whether it is a smooth flow or a violent stirring vortex; the degree of mixing of the materials can also be seen, such as whether there are lumps that are not mixed evenly or areas with obvious color differences. The visual window 71 can help quickly discover some unexpected situations, such as equipment failure in the tank body 10 (such as damage to the stirring paddle) or abnormal reactions of the materials (such as the generation of a large number of bubbles, discoloration, etc.).
[0095] The monitoring probe 72 can transmit the image information in the visual window 71 to the remote monitoring device. In this way, the operator does not need to be next to the tank body 10 all the time, and can check the mixing situation in the central control room or other remote locations. The monitoring probe 72 can also record the mixing process by video. These records can be used for subsequent quality analysis, troubleshooting or process optimization.
[0096] In the above solution, the monitoring probe 72 is used to photograph the interior of the tank body 10 through the visual window 71 , so that the mixed liquid situation inside the tank body 10 can be easily checked manually.
[0097] In some embodiments, the mixing device 100 further includes a lighting lamp 73 disposed on the tank body 10 . The lighting lamp 73 is located beside the monitoring probe 72 and is disposed toward the visual window 71 .
[0098] In many cases, the internal environment of the tank body 10 of the mixing device 100 may be relatively dim, especially for some tank bodies 10 with dark outer shells or complex internal structures. The lighting lamp 73 can provide sufficient light so that the visual window 71 can clearly display the situation inside the tank body 10. The monitoring probe 72 needs sufficient light to obtain a clear image. Even in an environment with a certain amount of natural light, there may be shadows inside the tank body 10 due to angles or obstructions. The lighting lamp 73 can eliminate these shadows, allowing the monitoring probe 72 to capture high-quality images, thereby more accurately monitoring the mixing process.
[0099] In the above solution, the problem of insufficient light in the monitoring environment can be compensated by the lighting lamp 73, thereby improving the clarity of the internal monitoring of the tank body 10.
[0100] In some embodiments, the can body 10 is a non-metallic can.
[0101] In the battery production process, if the tank 10 of the mixing device 100 is made of metal, during material mixing and stirring operations, the friction inside the tank 10 (such as the friction between the stirring blade and the wall of the tank 10, the friction between the material particles and the wall of the tank 10, etc.) can easily generate metal particles. When the metal particles enter the battery mixture, they may form an unexpected conductive path between the positive and negative electrodes inside the battery, which greatly increases the risk of short circuits in the battery cells.
[0102] In the above solution, the tank body 10 is made of non-metal, which can reduce the metal particles generated by the friction of the tank body 10, thereby reducing the short circuit risk of the battery cell for the mixed liquid in the battery field.
[0103] Figure 7 It is a schematic structural diagram of a mixing device in some other embodiments of the present application.
[0104] like Figure 7 As shown, in some embodiments, the mixing device 100 further includes a weighing sensor 80 , and the weighing sensor 80 is disposed at one end of the tank body 10 close to the feed port 11 .
[0105] The weighing sensor 80 usually works by using components such as pressure sensors or strain gauges. When the raw material enters the tank body 10 through the feed port 11, the weight of the tank body 10 near the feed port 11 will change. The weighing sensor 80 can convert this weight change into an electrical signal. For example, a strain gauge weighing sensor will deform as the weight of the tank body 10 increases. This deformation causes its resistance value to change. The resistance change is converted into a voltage signal through a circuit such as a Wheatstone bridge, and the voltage signal can be used as an indication of the weight change. These electrical signals can be transmitted to a controller or a data recording system. Through pre-calibration, the system can accurately calculate the weight of the raw material entering the tank body 10 based on the electrical signal. For example, during the system calibration process, the electrical signal value corresponding to a certain standard weight of raw material is known. Then, when a new raw material enters the tank body 10 and produces a similar electrical signal change, the actual weight of the raw material can be calculated through the proportional relationship.
[0106] In the above solution, the amount of raw materials entering the tank body 10 can be monitored by the weighing sensor 80, thereby improving the preparation accuracy of the mixed liquid.
