[0002] A stirring device is a mechanical equipment widely used in industrial production. It is mainly used to mix the components of different substances evenly to achieve the needs of reaction, processing and manufacturing. The stirring device is a device that continuously turns and stirs the materials through the rotation of the agitator to achieve material mixing. There are many different types of stirring and mixing devices nowadays. Different types of stirring devices are used in different scenarios, and the magnetic stirrer is one of them.

In the device, the main magnetic shaft drives the main magnetic block to rotate, and the rotation of the main magnetic block drives the secondary magnetic shaft to rotate together through the secondary magnetic block, and the rotation of the secondary magnetic shaft drives the stirring paddle disk to rotate to stir the material, and the rotation of the secondary magnetic shaft drives the connecting shaft to rotate synchronously, and the connecting shaft drives the main gear to rotate, and the rotation of the main gear drives the secondary gear to rotate, so that the secondary gear performs a circular motion around the outside of the main gear, and the movement of the secondary gear drives the stirring paddle seat to rotate through the rotating shaft, and the rotation direction of the stirring paddle seat is opposite to that of the stirring paddle disk, thereby improving the stirring effect of the magnetic stirrer. Although today's magnetic stirring can achieve a mixing and stirring effect for raw materials, there are still some problems when using it. The main problem is that due to the rapid rotation of the magnetic stirring mechanism at its center, some raw materials mixed with a large amount of solid mixtures will diffuse to the outside of the equipment. These raw materials will not be evenly mixed and will adhere to the inner wall of the equipment in large quantities, resulting in a waste of resources. The mixing effect of the raw materials cannot be improved, and the actual application effect is not good. Therefore, a magnetic suspension magnetic stirring device is proposed.

[0027] 1. In the present invention, a magnetic drive component, a side mixing component and a lower counter-mixing component are provided in a supporting manner. When the liquid is stirred and mixed, the raw materials are added into the interior of the stirring tank through the feeding pipe. At this time, the driving motor is turned on to drive the magnetic strip to rotate rapidly. The magnetic strip causes the magnetic field to change in real time, and continuously generates repulsive force for the suspended magnets, causing the second shaft to rotate rapidly step by step. The spoiler can stably increase the flow rate of the mixed liquid. The spoiler can drive the bottom brush plate to rotate synchronously while rotating. The bottom brush plate can clean the bottom of the equipment to prevent the solute from sinking to the bottom. As the flow rate of the mixed liquid increases, the triangular blades can be subjected to pressure to drive the mounting shaft to rotate as a whole, thereby driving the grinding roller to rotate. The rotating grinding roller can achieve the solution diffused to the outside of the stirring tank. The side mixing components are provided with a plurality of side mixing components in a circle on the inner side of the stirring tank, and the plurality of side mixing components can work simultaneously to achieve mixing of the mixed liquid. Through this design, not only the mixing treatment of the raw materials can be achieved, but also the grinding and crushing treatment of the mixed materials flowing outward during the rapid stirring of the raw materials can be achieved, thereby effectively improving the mixing effect of the mixed materials. The plurality of abrasive particles arranged on the outer surface of the grinding roller can improve the processing effect of the mixed materials, effectively solve the problem of the adhesion of the diffused raw materials on the inner wall, and avoid the waste of raw materials. At the same time, during the working process, the bottom of the equipment can be cleaned synchronously, so that some solutes that have settled to the bottom can be raised again, further improving the mixing effect of the equipment.

[0028] 2. In the present invention, an upper counter-mixing assembly is provided in a matching manner. When multiple side mixing assemblies rotate synchronously, multiple driving gears can drive the driven gear disc to rotate. The driven gear disc can drive the first counter-mixing spiral blade and the first shaft body at its bottom to rotate, and when the second shaft body rotates, it can also drive the second counter-mixing spiral blade outside to rotate. Since the spiral direction of the second counter-mixing spiral blade is opposite to that of the first counter-mixing spiral blade, the second counter-mixing spiral blade and the first counter-mixing spiral blade can achieve counter-mixing of the raw materials when they rotate. Through this design, during the operation of the upper counter-mixing assembly and the lower counter-mixing assembly, the first counter-mixing spiral blade The first hedging spiral blade and the second hedging spiral blade can generate opposite forces to achieve counter-mixing of raw materials, which can not only reduce energy consumption and shorten mixing time, but also achieve uniform mixing of raw materials. At the same time, the first hedging spiral blade and the second hedging spiral blade are provided with a first material hole and a second material hole, which can effectively prevent the damage of the spiral blade caused by the increase in resistance to the spiral blade during mixing due to increased viscosity of the material, thereby effectively protecting the spiral blade. The upper hedging mixing component and the side mixing component do not require additional driving energy to work, which further reduces the energy consumption of the equipment and improves the actual application effect of the equipment.

[0029] 3. In the present invention, a detachable limit shield and an upper counter-mixing assembly are provided in combination. The limit shield can effectively limit and protect the rotation of the suspended magnet, thereby ensuring the continuous working effect of the equipment. At the same time, when it is necessary to clean the internal structure of the equipment, the hydraulic telescopic frame is directly controlled to extend, and the hydraulic telescopic frame can lift the upper counter-mixing assembly as a whole until it is separated from the mixing tank. At this time, it is convenient to clean the inside of the mixing tank. Through this design, when it is necessary to inspect or clean the internal structure of the equipment, the modular disassembly of the equipment can be quickly realized, the operation is simple and fast, and the actual application effect of the equipment is improved.

[0049] The specific implementation method is as follows: when the liquid is stirred and mixed, the raw materials are added into the inside of the stirring tank 4 through the feeding pipe 10. At this time, the driving motor 82 is turned on to drive the magnetic strip 81 to rotate rapidly. The magnetic strip 81 causes the magnetic field to change in real time, and continuously generates repulsive force for the suspended magnet 136, causing the second shaft 135 to gradually rotate rapidly. The spoiler 133 can stably increase the flow rate of the mixed liquid. The spoiler 133 can drive the bottom brush plate 134 at the bottom to rotate synchronously while rotating. The bottom brush plate 134 can clean the bottom of the equipment to prevent the solute from sinking to the bottom. As the flow rate of the mixed liquid increases, the triangular blade 122 can be subjected to pressure to drive the mounting shaft 123 to rotate as a whole, thereby driving the grinding roller 124 to rotate. The rotating grinding roller 124 can achieve a certain grinding and rolling treatment for the solute diffused to the outside of the stirring tank 4, thereby improving the mixing effect of the solute in the mixed liquid.

[0050] Through this design, not only can the mixing process of the raw materials be achieved, but also the grinding and crushing process of the mixed materials flowing outward during the rapid stirring of the raw materials can be achieved, thereby effectively improving the mixing effect of the mixed materials. The multiple grinding particles 125 arranged on the outer surface of the grinding roller 124 can improve the processing effect of the mixed materials, effectively solve the problem of the diffused raw materials adhering to the inner wall, and avoid the waste of raw materials. At the same time, during the working process, the bottom of the equipment can be cleaned synchronously, so that some solutes that have settled to the bottom can be raised again, further improving the mixing effect of the equipment.

[0051] The upper counter-hedge mixing assembly 9 includes a top cover 91, on the bottom surface of which a driven gear disc 92 is rotatably mounted via a rotating shaft, on the bottom surface of which a first shaft body 94 is longitudinally fixedly mounted, on the outer surface of which a first counter-hedge spiral blade 93 is fixedly mounted, and inside of which a plurality of first material holes 95 are arranged.

[0052] The specific implementation method is as follows: when multiple side mixing components 12 rotate synchronously, multiple driving gears 121 can drive the driven gear plate 92 to rotate, and the driven gear plate 92 can drive the first hedging spiral blade 93 and the first shaft body 94 at its bottom to rotate, and when the second shaft body 135 rotates, it can also drive the second hedging spiral blade 131 outside it to rotate. Since the spiral directions of the second hedging spiral blade 131 and the first hedging spiral blade 93 are opposite, the second hedging spiral blade 131 and the first hedging spiral blade 93 can achieve hedging mixing of the raw materials when they rotate.

[0053] Through this design, during the operation of the upper counter-mixing component 9 and the lower counter-mixing component 13, the first counter-mixing spiral blade 93 and the second counter-mixing spiral blade 131 can generate opposite forces to achieve counter-mixing of the raw materials, which can not only reduce energy consumption and shorten mixing time, but also achieve uniform mixing of the raw materials. At the same time, the first counter-mixing spiral blade 93 and the second counter-mixing spiral blade 131 are provided with a first material hole 95 and a second material hole 132, which can effectively prevent the damage of the spiral blades caused by the increased resistance to the spiral blades during stirring due to the increase in material viscosity, thereby effectively protecting the spiral blades. In addition, the upper counter-mixing component 9 and the side mixing component 12 do not require additional driving energy to work, which further reduces the energy consumption of the equipment and improves the actual application effect of the equipment.

[0054] The second hedging spiral blade 131 is located above the spoiler 133 , and the spiral direction of the second hedging spiral blade 131 is opposite to that of the first hedging spiral blade 93 .

[0056] Through this design, when the internal structure of the equipment needs to be inspected or cleaned, the modular disassembly of the equipment can be quickly achieved, the operation is simple and fast, and the actual application effect of the equipment is improved.

[0057] Working principle: when the liquid is stirred and mixed, the raw materials are added into the inside of the stirring tank 4 through the feeding pipe 10. At this time, the driving motor 82 is turned on to drive the magnetic strip 81 to rotate rapidly. The magnetic strip 81 causes the magnetic field to change in real time, and continuously generates repulsive force for the suspended magnet 136, causing the second shaft 135 to rotate gradually and rapidly. The spoiler 133 can stably increase the flow rate of the mixed liquid. The spoiler 133 can drive the bottom brush plate 134 at the bottom to rotate synchronously while rotating. The bottom brush plate 134 can realize the cleaning of the bottom of the equipment to prevent the solute from sinking to the bottom. As the flow rate of the mixed liquid increases, the triangular blade 122 can be subjected to pressure to drive the mounting shaft 123 to rotate as a whole, thereby driving the grinding roller 124 to rotate. The rotating grinding roller 124 can realize a certain grinding and rolling treatment of the solute diffused to the outside of the stirring tank 4, thereby improving the mixing effect of the solute in the mixed liquid. The side mixing assembly 12 is provided with a plurality of side mixing assemblies 12 in a circle on the inner side of the stirring tank 4, and the plurality of side mixing assemblies 12 can work simultaneously to achieve mixing of the mixed liquid.

Since the spiral directions of the second hedging spiral blade 131 and the first hedging spiral blade 93 are opposite, the second hedging spiral blade 131 and the first hedging spiral blade 93 can achieve hedging mixing of the raw materials when they rotate. During the working process of the upper hedging mixing component 9 and the lower hedging mixing component 13, the first The hedging spiral blade 93 and the second hedging spiral blade 131 can generate opposite forces to achieve the hedging mixing of the raw materials, which can not only reduce energy consumption and shorten the mixing time, but also achieve uniform mixing of the raw materials. At the same time, the first hedging spiral blade 93 and the second hedging spiral blade 131 are provided with a first material hole 95 and a second material hole 132, which can effectively prevent the damage of the spiral blade caused by the increase in resistance to the spiral blade during mixing due to the increase in material viscosity, effectively protect the spiral blade, and the upper hedging mixing component 9 and the side mixing component 12 do not need to be driven by additional driving energy, which further reduces the energy consumption of the equipment;

[0059] The limiting shield 14 can effectively limit and protect the rotation of the suspended magnet 136 to ensure the continuous working effect of the equipment. At the same time, when it is necessary to clean the internal structure of the equipment, the hydraulic telescopic frame 3 is directly controlled to extend.
