[0002] Chemical material stirring refers to the process of mechanically stirring chemical raw materials or products through a stirring device during the production process of the chemical industry to achieve uniform mixing of the materials. The purpose of stirring is to ensure that the components in the reactants or mixtures are evenly distributed, improve the reaction efficiency, and ensure the product quality.
[0003] A stirrer is a device used to mix and stir materials during the chemical production process. In the chemical industry, when it is necessary to mix two liquid substances, it is necessary to pay attention to whether the heat generated and the reaction intensity during the mixing process will affect the stirring environment, and whether other substances will be generated when the mixed liquid changes the stirring environment, which will affect the mixing reaction effect. For example, when certain acids, alkalis, oxidants, reductants, and catalysts are mixed with related liquids, precipitation may easily occur due to too high local concentration, or violent chemical reactions may be triggered, and even a large amount of heat may be generated, leading to boiling or explosion, which will affect the result of the mixing reaction. In the prior art, when adding chemical substances that are prone to violent reactions, they are generally slowly injected into the mixing barrel through a guide pipe, and mixed while stirring. However, during the injection process, there may still be a possibility of uneven mixing due to unreasonable stirring or the density of the solution itself, resulting in too high a concentration of the mixed solution in some solutions, which will affect the result of the mixing. Content of the Utility Model
[0004] The purpose of the utility model is to provide a chemical material stirrer to solve the technical problem that uneven mixing may occur in the prior art, resulting in too high a concentration of the mixed solution in some solutions, which will affect the result of the mixing.

[0012] The beneficial effects of the present utility model:
[0013] 1.

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Such as Figures 1-4As shown in the figure, a chemical material stirrer includes a transmission rod 14 disposed inside a stirring barrel 1. A liquid guide cavity 12 is formed inside the transmission rod 14. A stirring paddle 10 is provided at the bottom of the transmission rod 14. The stirring paddle 10 is used to mix the liquid. An injection channel 15 is formed inside the stirring paddle 10. One end of the injection channel 15 is connected to the liquid guide cavity 12, and the other end is disposed on the surface of the stirring paddle 10. The liquid guide cavity 12 can transport the liquid to be mixed into the injection channel 15, and drive the output port of the injection channel 15 to move inside the stirring barrel 1 through the stirring paddle 10. A sealing through-block 16 for controlling the through state of the injection channel 15 is disposed at a position close to the surface of the stirring paddle 10 inside the injection channel 15. The sealing through-block 16 is made of silica gel and has a certain elasticity. A through-hole that is squeezed and sealed is provided in the middle of the sealing through-block 16. The liquid to be mixed can expand the through-hole by applying pressure to the through-hole to realize the injection of the liquid to be mixed. A driving component that cooperates with the transmission rod 14 is provided on the stirring barrel 1. The driving component is used to drive the transmission rod 14 to rotate. A liquid preparation component is provided on the stirring barrel 1. The output end of the liquid preparation component is connected to the liquid guide cavity 12. The liquid preparation component is responsible for transporting the liquid to be mixed into the liquid guide cavity 12 and applying a certain pressure to the liquid guide cavity 12.
[0023] In some specific embodiments, in order to drive the transmission rod 14, the transmission component includes a motor 3 fixedly connected to the stirring barrel 1. The output end of the motor 3 is fixedly connected to an output rod 13. The output rod 13 is coaxially and fixedly connected to the transmission rod 14. The motor 3 drives the transmission rod 14 to rotate through the output rod 13, thereby realizing the stirring of the liquid.
[0024] In some specific embodiments, in order to inject liquid into the liquid guide cavity 12, the liquid preparation component includes a storage tank 9 fixedly connected to the stirring barrel 1. The storage tank 9 is used to store the liquid to be mixed. A liquid pressing cylinder body 2 is fixedly connected to the inner top of the stirring barrel 1. The liquid pressing cylinder body 2 is used to apply pressure to the liquid to be mixed. A liquid guide pipe 11 is connected between the storage tank 9 and the liquid pressing cylinder body 2 for transporting the liquid to be mixed. The output rod 13 and the transmission rod 14 penetrate through the liquid pressing cylinder body 2 and are rotatably connected to the liquid pressing cylinder body 2. A sealing ring that cooperates with the output rod 13 and the transmission rod 14 is provided on the liquid pressing cylinder body 2. An electric telescopic rod 5 is fixedly connected to the inner top of the liquid pressing cylinder body 2. The output end of the electric telescopic rod 5 is fixedly connected to a liquid pressing plate 4 that is slidably matched with the liquid pressing cylinder body 2. The liquid pressing plate 4 is slidably sleeved on the output rod 13. A sealing ring that cooperates with the liquid pressing cylinder body 2 and the output rod 13 is provided on the liquid pressing plate 4, so as to ensure the sealing effect at the edge of the liquid pressing plate 4. One-way valves are cooperatively provided on both the liquid guide pipe 11 and the liquid pressing plate 4, so that the liquid to be mixed can only flow along the flow direction of the storage tank 9, the liquid guide pipe 11, the liquid pressing cylinder body 2, and the liquid guide cavity 12. An injection hole 6 communicating with the liquid guide cavity 12 is formed on the transmission rod 14. The liquid guide cavity 12 is connected to the inside of the liquid pressing cylinder body 2 through the injection hole 6.
[0025] In some specific embodiments, in order to improve the mixing effect, a mixing assembly is provided on the transmission rod 14. The mixing assembly includes a mixing plate 7. A diversion channel communicating with the liquid guide cavity 12 is formed inside the mixing plate 7. A plurality of groups of mixing holes 8 communicating with the diversion channel are arranged at equal intervals on the mixing plate 7. The liquid inside the liquid guide cavity 12 can be injected into the stirring barrel 1 along the diversion channel and the mixing holes 8. The multiple groups of stirring barrels 1 input together, thereby improving the input efficiency.
[0026] In some specific embodiments, in order to avoid too high a concentration of the liquid to be mixed near the mixing holes 8, the mixing plate 7 is perpendicularly arranged with respect to the transmission rod 14, and the mixing plate 7 is rotationally inclined along the axis. When the mixing plate 7 moves under the action of the transmission rod 14, it will drive the solution inside the stirring barrel 1 to flow in a certain direction all the time, thereby driving the liquid to be mixed output from the mixing holes 8 to flow in this direction and accelerating the mixing with other solutions.
[0027] In some specific embodiments, in order to avoid the backflow of the liquid near the mixing holes 8, a rubber through-block for controlling the through state of the mixing holes 8 is cooperatively arranged inside each group of mixing holes 8. The rubber through-block has the same principle as the sealing through-block 16. The liquid to be mixed inside the mixing holes 8 extrudes the rubber through-block, making the inside of the rubber through-block in a through state to realize the injection of the liquid. At the same time, the solution outside the mixing holes 8 cannot enter the inside of the mixing holes 8 due to insufficient pressure.
[0028] To facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will be described below in combination with a specific application scenario:
[0029] When other solutions need to be added to the solution, the liquid to be mixed can be poured into the storage box 9. The liquid enters the upper part inside the liquid pressing cylinder body 2 through the liquid guide pipe 11. The electric telescopic rod 5 drives the liquid pressing plate 4 to move up and down intermittently. Since one-way valves are provided on both the liquid guide pipe 11 and the liquid pressing plate 4, the liquid inside the liquid guide pipe 11 and near the liquid pressing plate 4 can only flow towards the inside of the liquid guide cavity 12. When the liquid pressing plate 4 moves up, the liquid pressing plate 4 extrudes the liquid to be mixed, so that the liquid to be mixed enters the bottom of the liquid pressing plate 4 through the one-way valve. At this time, under the action of the one-way valve, there is no liquid backflow inside the liquid guide pipe 11. Then the electric telescopic rod 5 drives the liquid pressing plate 4 to descend, and the one-way valve closes, so that the liquid to be mixed inside the liquid guide pipe 11 enters above the liquid pressing plate 4. At the same time, the liquid to be mixed below the liquid pressing plate 4 enters the liquid guide cavity 12 from the liquid injection hole 6 under the action of pressure and enters the stirring barrel 1 through the injection channel 15 on the stirring paddle 10. The motor 3 drives the transmission rod 14 to rotate, thereby driving the stirring paddle 10 to rotate to realize the stirring of the liquid. Since the output port of the injection channel 15 is arranged on the stirring paddle 10, the movement of the stirring paddle 10 will push the liquid to flow, so that the liquid is mixed more evenly;
[0030] On one side of the transmission rod 14, a mixing plate 7 is further provided. The mixing plate 7 is arranged obliquely along the axis and rotates. When the transmission rod 14 drives the mixing plate 7 to move, the mixing plate 7 will push the solution inside the stirring barrel 1 to move in one direction, thereby accelerating the liquid flow effect. At the same time, the liquid to be mixed inside the liquid guiding cavity 12 will enter the solution along the channel inside the mixing plate 7, thereby improving the mixing efficiency of the liquid to be mixed.
[0031] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as being used to limit the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
