Description

Technical Field

[0001] The utility model relates to the technical field of dynamic mixer accessories, in particular to a dynamic mixing core and a dynamic mixer using the dynamic mixing core. Background Art

[0002] Currently in the chemical industry, mixers are very common key components. Mixers are divided into dynamic mixers and static mixers. Static mixers have fast response and can work continuously, but static mixers have the disadvantage of poor mixing effect. Therefore, dynamic mixers are mostly used in equipment with high requirements on mixing effect. For dynamic mixers, some mixing cylinders can ensure sufficient mixing of multi-component liquids by shaking them greatly. This makes the machine structure complicated and will cause impact on the entire machine. Therefore, most dynamic mixers use the mixing core to rotate the stirring blades on the mixing core to achieve dynamic mixing effects. The stirring blades of the mixing core on the market are generally provided with threaded strips on the middle connecting shaft or convex strips on the connecting shaft. When stirring, the liquid is driven to rotate by the blades to achieve stirring and mixing of the liquid. However, since the blades are regularly distributed on the connecting shaft, the liquid will only flow in the same direction during stirring, resulting in uneven liquid flow, which will affect the mixing effect between the liquids.

[0003] The technical problem to be solved by the present application is to design a dynamic mixing core that can make the liquid flow evenly during stirring, thereby improving the mixing effect, and a dynamic mixer using the dynamic mixing core. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a dynamic mixing core designed to make the liquid uniformly fluid during stirring, thereby improving the mixing effect, and a dynamic mixer using the dynamic mixing core.

[0005] The technical solution adopted by the utility model is: a dynamic mixing core, including a connecting shaft, the connecting shaft is provided with a plurality of stirring blade units and a plurality of reverse tooth units for preventing liquid backflow in sequence from top to bottom, each reverse tooth unit includes reverse flow teeth respectively arranged opposite to each other on the connecting shaft, and the reverse flow teeth are provided with a reverse flow notch.

[0006] In some embodiments, each reverse tooth unit is provided with two reverse flow teeth, the reverse flow teeth include a first stopper and a second stopper, and the reverse flow gap is provided between the first stopper and the second stopper.

[0007] In some embodiments, a rotor shape is formed between the first stopper and the second stopper.

[0008] In some embodiments, the stirring blade unit includes rotor blades oppositely arranged on the connecting shaft respectively, and each stirring blade unit is provided with two rotor blades.

[0009] In some embodiments, the stirring blade units are oppositely arranged on the connecting shaft in sequence from top to bottom.

[0010] In some embodiments, the reverse tooth units are oppositely arranged on the connecting shaft in sequence from top to bottom.

[0011] In some embodiments, a single reverse flow tooth is located between two adjacent rotor blades.

[0012] In some embodiments, the rotor directions of the rotor blades are arranged in the opposite direction to the rotor direction of the reverse flow teeth.

[0013] In some embodiments, a connecting head is provided at the upper end of the connecting shaft, and the rotor blades in the stirring blade unit at the uppermost part of the connecting shaft are connected to the connecting head.

[0014] A dynamic mixer is provided with any one of the dynamic mixing cores in the above embodiments.

[0015] The utility model has the following technical effects: By providing a reverse tooth unit on the connecting shaft, each reverse tooth unit includes reverse flow teeth oppositely arranged on the connecting shaft respectively, and reverse flow notches are provided on the reverse flow teeth. Therefore, when the connecting shaft drives the stirring blade unit to stir and mix the liquid, the stirring blade unit will cause the liquid to generate a positive flow, while the reverse tooth unit will cause the liquid to generate a reverse flow. At this time, due to the reverse flow notches provided on the reverse flow teeth, the occurrence of reverse flow can be reduced. And when stirring and rotating, the liquid will form a turbulent flow under the combined action of the stirring blade unit and the reverse tooth unit. Since the reverse flow teeth are provided with reverse flow notches, two radial stirring pins will be formed on the reverse flow teeth, thereby increasing the shearing effect of the stirring material, so that the liquid flows more stably and uniformly during stirring, thereby improving the mixing effect on the liquid.

Specific implementation mode

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-4 , the present invention provides a technical solution: a dynamic mixing core, including a connecting shaft 1, on which several stirring blade units 2 and several reverse tooth units 3 for preventing liquid backflow are sequentially arranged from top to bottom. Each reverse tooth unit 3 includes two reverse flow teeth 30, and the two reverse flow teeth 30 in the same reverse tooth unit 3 are oppositely arranged at the same horizontal height of the connecting shaft 1. The reverse flow tooth 30 includes a first stop block 32 and a second stop block 33, and the first stop block 32 and the second stop block 33 are connected in an inverted V shape, so a reverse flow notch 31 is formed between the first stop block 32 and the second stop block 33. Therefore, when the connecting shaft 1 drives the stirring blade unit 2 and the reverse tooth unit 3 to rotate to drive the liquid to rotate for mixing, at this time, the stirring blade unit 2 will cause the liquid to generate a positive flow, while the reverse tooth unit 3 will cause the liquid to generate a reverse flow. At this time, since the reverse flow notch 31 is provided on the reverse flow tooth 30, the occurrence of backflow can be reduced. And because the two sides of the reverse flow notch 31 are the first stop block 32 and the second stop block 33, as the connecting shaft 1 rotates, two radial stirring pins relative to the connecting shaft 1 are formed on the reverse flow tooth 30, which will greatly increase the radial shear force of the stirring material, so that the liquid can flow more stably and uniformly during stirring. And by providing the reverse tooth unit 3, turbulence will be formed when stirring the liquid under the combined action of the stirring blade unit 2 and the reverse tooth unit 3, so that the stirring material can be fully mixed. And because the reverse flow notch 31 is provided on the reverse flow tooth 30, the first stop block 32 and the second stop block 33 on the reverse flow tooth 30 will form two radial stirring pins relative to the connecting shaft 1, that is, the whole reverse tooth unit 3 forms four radial stirring pins, thus increasing the shearing effect of the stirring material, so that the liquid can flow more stably and uniformly during stirring, thereby improving the mixing effect on the liquid.

[0023] In order to reduce the resistance of the dynamic mixing core during rotation and stirring in the liquid, the shape between the first stopper 32 and the second stopper 33 is in the shape of a rotor blade, so as to reduce the resistance with the liquid and enable the dynamic mixing core to be more stable during stirring.

[0024] The stirring blade unit 2 includes rotor blades 20 respectively arranged oppositely on the connecting shaft 1. Each stirring blade unit 2 is provided with two rotor blades 20, and the two rotor blades 20 in the same stirring blade unit 2 are also arranged oppositely at the same horizontal height of the connecting shaft 1. In order to ensure that the liquid can be regularly rotated and mixed during stirring, the stirring blade units 2 are arranged oppositely on the connecting shaft 1 from top to bottom in sequence, and the reverse tooth unit 3 is also arranged oppositely on the connecting shaft 1 from top to bottom in sequence. Each reverse flow tooth 30 is arranged in the middle of two adjacent rotor blades 20. From the top view angle of the connecting shaft 1, longitudinally, the reverse flow tooth 30 is arranged between the left and right rotor blades 20. From the front view angle of the connecting shaft 1, transversely, the reverse flow tooth 30 is arranged between the upper and lower rotor blades 20, so as to better form a turbulent flow between the forward flow and the reverse flow.

[0025] In order to further improve the shearing effect of the stirring material, the rotor directions of the rotor blades 20 and the reverse flow teeth 30 are arranged in opposite directions. Therefore, when stirring and mixing the liquid, both forward flow and reverse flow will be generated simultaneously, so a turbulent flow will be formed. However, by providing a reverse flow notch 31, the occurrence of reverse flow will be reduced and the shearing effect will be increased.

[0026] In order to ensure that the sealing ring at the end face is not damaged during stirring after the mixing core is inserted into the mixing tube, a connecting head 10 is provided at the upper end of the connecting shaft 1, and the two rotor blades 20 in the stirring blade unit 2 located at the top of the connecting shaft 1 are connected to the lower end of the connecting head 10. Also, because the rotor blades 20 themselves are in the shape of rotor blades, after the connecting shaft 1 is inserted into the mixing tube, the uppermost stirring blade unit 2 can prevent the liquid from flowing out and damaging the sealing ring.

[0027] In order to improve the stiffness of the rotor blades 20 and the reverse flow teeth 30 and avoid rusting, which may affect the chemical reaction between the liquids, the rotor blades 20 and the reverse flow teeth 30 are both made of 304 stainless steel or 316L stainless steel materials.

[0028] In order to achieve dead - angle - free stirring of the liquid, the outer diameters of the stirring blade unit 2 and the reverse tooth unit 3 are equal.

[0029] Embodiment 2: This embodiment provides another technical solution, a dynamic mixer, which uses any one of the dynamic mixing cores in the above - mentioned Embodiment 1, so as to avoid reverse flow of the liquid during stirring and mixing of the liquid, thereby improving the stirring and mixing effect.

[0030] Working principle of the utility model: A number of reverse tooth units 3 are sequentially arranged on the connecting shaft 1 from top to bottom. Each reverse tooth unit 3 includes reverse flow teeth 30 which are oppositely arranged on the connecting shaft 1 respectively. A reverse flow notch 31 is provided on the reverse flow tooth 30. Therefore, when the connecting shaft 1 drives the stirring blade unit 2 to stir and mix the liquid, if the liquid flows back in the gap between the stirring blade units 2, the reverse flow notch 31 can effectively block the flowing-back liquid, thus avoiding the reverse flow of the liquid. And by providing the reverse tooth unit 3, when stirring and rotating, the liquid will form a turbulent flow under the combined action of the stirring blade unit 2 and the reverse tooth unit 3. And because the reverse flow tooth 30 is provided with the reverse flow notch 31, the first stop block 32 and the second stop block 33 on the reverse flow tooth 30 will form two radial stirring pins relative to the connecting shaft 1, that is, it is equivalent to the whole reverse tooth unit 3 forming four radial stirring pins, thereby increasing the shearing effect of the stirred material, so that the liquid flows more stably and uniformly when stirring and flowing, and thus improving the mixing effect on the liquid.

[0031] Finally, it should be noted that the above are only preferred examples of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
