Description

Technical Field

[0001] The invention relates to the technical field of mixing machinery, in particular to a dynamic mixing device. Background Art

[0002] Polylactic acid fiber is becoming more and more popular as a sustainable textile material due to its biocompatibility, biodegradability and biorenewability. However, polylactic acid has a low melting point and poor heat resistance, so its application range is greatly limited. Since the combination of left-handed polylactic acid and right-handed polylactic acid in equal proportions can form a stereocomposite crystal structure, its melting point is about 50°C higher than that of a single-component crystal. Therefore, the preparation of polylactic acid fiber with a fully stereocomposite structure will greatly broaden the application range of polylactic acid fiber.

[0003] In the prior art, the preparation of polylactic acid fibers with a full stereocomposite structure can only be done by melt spinning. However, the preparation process of full stereocomposite polylactic acid fibers has very strict requirements on the mixing effect of the two melts. If the mixing is not uniform, the processability may be reduced. Summary of the invention

[0085] In view of this, the present invention provides a dynamic mixing device, which can achieve sufficient and uniform mixing of multiple components, thereby being more suitable for practical use.

[0086] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of a dynamic mixing device proposed according to the present invention, its specific implementation, structure, features and effects, in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0087] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B. Specifically, it is understood that: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may be met.

[0088] See attached Figure 1 -Attached Fig.18The dynamic mixing device provided in the embodiment of the present invention includes a first mixer 13, a second mixer 17, a spoiler 18, a rotating shaft 16 and a rotary power driving member. One end of the rotating shaft 16 is fixedly connected to the top surface of the first mixer 13, and the other end of the rotating shaft 16 is fixedly connected to the output shaft of the rotary power driving member. The bottom surface 35 of the first mixer 13 and the top surface 23 of the second mixer 17 correspond to form a mixing assembly, and a first accommodating space 31 is formed between the bottom surface 35 of the first mixer 13 and the top surface 23 of the second mixer 17. The spoiler 18 is eccentrically arranged in the first accommodating space 31. The upper and lower sides of the first accommodating space 31 are both connected to the outside.

[0089] The dynamic mixing device provided by the present invention receives the medium to be mixed through the upper side of the first accommodating space 31. After the medium to be mixed is mixed in the first accommodating space 31, since the rotating shaft 16 is fixedly connected to the output shaft of the rotary power driving member, after the rotary power driving member is started, as the output shaft of the rotary power driving member rotates, the rotating shaft 16 and the first mixer 13 fixedly connected to the rotating shaft 16 also rotate accordingly. In this case, since the spoiler 18 is eccentrically arranged in the first accommodating space 31, the spoiler 18 can rotate in a circle with the rotating shaft 16 as the rotation center as the rotary power output shaft rotates, thereby achieving stirring of the medium to be mixed accommodated in the first accommodating space 31. Therefore, it can provide a shearing force to the medium to be mixed in the first accommodating space 31, and at the same time achieve stirring of the medium to be mixed in the first accommodating space 31, thereby achieving uniform stirring of the medium to be mixed in the first accommodating space 31, and it is simple to operate and has good application prospects.

[0090] The dynamic mixing device further comprises an upper cover 1. A first through hole 34 is provided on the upper cover 1, and the rotating shaft 16 is passed through the first through hole 34. A plurality of second through holes 4 are provided on the upper cover 1. One end of the second through hole 4 is connected to the outside, and the other end of the second through hole 4 is connected to the upper side of the first accommodating space 31. When the upper cover 1 is not provided, the medium to be mixed needs to be received by the top surface of the first mixer 13 to receive the medium to be mixed, and then, through the connection between the upper side of the first mixer 13 and the first accommodating space 31, the medium to be mixed received by the top surface of the first mixer 13 enters the first accommodating space 31. Since the top surface area of ​​the first mixer 13 is large, the area receiving the medium to be mixed is large, and the problem of the medium to be mixed running off easily occurs. On this basis, when the upper cover 1 is provided, and through a plurality of second through holes 4, the medium to be mixed can reach the receiving point of the first mixer 13 through one of the through holes 4. In this embodiment, there are two second through holes 4. After the medium to be mixed reaches the receiving point of the first mixer 13 in two ways, the medium to be mixed enters the first accommodating space 31 through the upper side of the first accommodating space 31, which can reduce the area of ​​the receiving point between the medium to be mixed and the first mixer 13, which is equivalent to guiding the medium to be mixed through the second through hole 4, and can avoid the problem of the medium to be mixed running off. In this embodiment, the second through hole 4 first moves in the horizontal direction, and then turns to a vertical state to form an entry passage for the medium to be mixed, which can effectively collect and receive the medium to be mixed on the upper side of the first mixer 13.

[0091] The dynamic mixing device further comprises a bottom shell 6. A second accommodating space 30 is provided between the bottom shell 6 and the second mixer 17. A third through hole 27 is provided on the bottom shell 6. The lower side of the first accommodating space 31 is communicated with the second accommodating space 30. One end of the third through hole 27 is communicated with the second accommodating space 30, and the other end of the third through hole 27 is communicated with the outside world. In the case where the bottom shell 6 is not provided, since the first accommodating space 31 is communicated with the outside world through the lower side of the second mixer 17 to collect the mixed medium, since the area of ​​the bottom surface 28 of the second mixer 17 is large, a receiving container with a larger caliber is required. In this case, since the caliber of the receiving container is large, it is easy to cause the mixed medium collected in the receiving container to splash out. After the bottom shell 6 is provided, the mixed medium can be first gathered in the second accommodating space 30, and the gathered mixed medium is further collected through the third through hole 27. In this case, the second accommodating space 30 once again mixes the mixed medium, so that the mixed medium can be mixed more fully. In addition, since the diameter of the third through hole 27 is relatively small, the diameter of the receiving port of the receiving container used can also be reduced. In this case, the problem of splashing of the mixed medium caused by the receiving container with a larger diameter can be avoided.

[0092] The dynamic mixing device may also include an upper cover 1 and a bottom shell 6 at the same time. In this case, a third accommodating space 19 is formed between the upper cover 1 and the bottom shell 6, and the mixing assembly is accommodated in the third accommodating space 19. A first through hole 34 is provided on the upper cover 1, and the rotating shaft 16 is inserted into the first through hole 34. A plurality of second through holes 4 are provided on the upper cover 1. One end of the second through hole 4 is connected to the outside, and the other end of the second through hole 4 is connected to the upper side of the first accommodating space 31. When the upper cover 1 is not provided, the medium to be mixed needs to be received by the top surface of the first mixer 13 to receive the medium to be mixed, and then, through the communication between the upper side of the first mixer 13 and the first accommodating space 31, the medium to be mixed received on the top surface of the first mixer 13 enters the first accommodating space 31. Since the top surface area of ​​the first mixer 13 is large, the area receiving the medium to be mixed is large, and the problem of the medium to be mixed running away is easy to occur. On this basis, when the upper cover 1 is provided, and through a plurality of second through holes 4, the medium to be mixed can reach the receiving point of the first mixer 13 through one of the through holes 4. In this embodiment, there are two second through holes 4. After the medium to be mixed reaches the receiving point of the first mixer 13 in two ways, the medium to be mixed enters the first receiving space 31 through the upper side of the first accommodating space 31, which can reduce the area of ​​the receiving point between the medium to be mixed and the first mixer 13, which is equivalent to guiding the medium to be mixed through the second through hole 4, and can avoid the problem of the medium to be mixed running off. In this embodiment, the second through hole 4 first moves in the horizontal direction, and then turns to a vertical state to form an entry passage for the medium to be mixed, so that the medium to be mixed can be effectively collected and received on the upper side of the first mixer 13. A second accommodating space 30 is provided between the bottom shell 6 and the second mixer 17. A third through hole 27 is provided on the bottom shell 6. The lower side of the first accommodating space 31 is connected to the second accommodating space 30. One end of the third through hole 27 is connected to the second accommodating space 30, and the other end of the third through hole 27 is connected to the outside world. In the case where the bottom shell 6 is not provided, since the first accommodating space 31 is connected to the outside world through the lower side of the second mixer 17 to collect the mixed medium, since the area of ​​the bottom surface 28 of the second mixer 17 is large, a larger caliber receiving container is required. In this case, due to the larger caliber of the receiving container, it is easy to cause the mixed medium collected in the receiving container to splash out. After the bottom shell 6 is provided, the mixed medium can be first gathered in the second accommodating space 30, and the gathered mixed medium is further collected through the third through hole 27. In this case, the second accommodating space 30 once again mixes the mixed medium, so that the mixed medium can be mixed more fully. In addition, since the caliber of the third through hole 27 is small, the caliber of the receiving port of the receiving container used can also be reduced. In this case, the problem of the mixed medium splashing due to the receiving container with a larger practical caliber can be avoided.In this case, the advantages of the upper cover 1 and the bottom shell 6 are combined to ensure that the dynamic mixer provided by the embodiment of the present invention can have a collecting and guiding effect on the medium to be mixed and the mixed medium.

[0093] Among them, one of the corresponding side surfaces of the upper cover 1 is provided with a downward flange 7. In this case, the assembly position between the upper cover 1 and the bottom shell 6 can be limited by the flange 7 to ensure the centering assembly between the upper cover 1 and the bottom shell 6.

[0094] The inner distance between the two flanges 7 is greater than the width of the bottom shell 6 in the same direction, so that when the upper cover 1 and the bottom shell 6 are covered, there is a gap 33 between at least one side of the flange 7 and the outer edge of the bottom shell 6. In this case, the upper cover 1 and the bottom shell 6 can still be assembled together even if there is a slight error in the shape, which can enhance the matching effect between the various parts of the dynamic mixing device provided by the embodiment of the present invention.

[0095] The dynamic mixing device further includes a sealing plate 10. The sealing plate 10 is provided with fourth through holes 11, and the number of the fourth through holes 11 corresponds to the number of the second through holes 4. The sealing plate 10 is arranged between the upper cover 1, and a flow channel 14 is arranged between the sealing plate 10 and the first mixer 13. A plurality of fifth through holes 15 are arranged in the flow channel 14. The second through hole 4 is connected to the flow channel 14 through the fourth through hole 11, and the flow channel 14 is connected to the upper side of the first accommodating space 31 through the fifth through hole 15. In this case, after the medium to be mixed passes through the second through hole 4, it is guided into the flow channel 14 through the fourth through hole 11, and under the sealing effect of the sealing plate 10, leakage of the medium to be mixed can be avoided.

[0096] The bottom surface of the upper cover 1 is provided with a first groove 12, and the top surface of the sealing plate 10 is provided with a first protrusion 32, and the shape of the first groove 12 matches the shape of the first protrusion 32. Alternatively, the bottom surface of the upper cover 1 is provided with a second protrusion, and the top surface of the sealing plate 10 is provided with a second groove, and the shape of the second protrusion matches the shape of the second groove. In this case, the alignment between the cover 1 and the sealing plate 10 is ensured by the assembly between the first groove 12 and the first protrusion 32, or by the assembly between the second protrusion and the second groove.

[0097] The vertical projections of the sealing plate 10 and the bottom shell 6 are the same. In this case, the sealing effect of the medium to be mixed in the flow channel 14 can be better ensured.

[0098] The orthographic projection of the flow channel 14 in the vertical direction is in the shape of a maze. In this case, since the length of the flow channel is relatively long, the flow of the medium to be mixed in the flow channel can be extended, and the chance of the medium to be mixed in the flow channel is increased, so the mixing effect of the medium to be mixed can be better guaranteed.

[0099] The flow channels 14 are connected as a whole to form a passage. In this case, each component of the medium to be mixed can be carried in the same flow channel 14 at the same time, which can better ensure the mixing effect of the medium to be mixed.

[0100] The edge of the top surface 23 of the second mixer 17 is provided with a slope 21, and the top edge of the slope 21 contacts the bottom surface 35 of the first mixer 13. In this case, the gravity caused by the slope 21 can be used to reduce the leakage of the medium to be mixed at the contact position of the first mixer 13 and the second mixer 17 without adding a sealing ring.

[0101] Among them, a conical protrusion 22 is provided at the center of the top surface 23 of the second mixer 17, and the conical protrusion 22 is accommodated in the first accommodating space 31. In this case, the medium to be mixed received at the center of the first accommodating space 31 can be driven to the accommodating space outside the conical protrusion 22 by the gravity generated by the conical protrusion 22, and can be adapted to the eccentrically arranged spoiler 18, so that the chance of the medium to be mixed contacting the spoiler 18 is increased, thereby increasing the chance of the medium to be mixed being stirred, thereby increasing the mixing uniformity of the medium to be mixed.

[0102] Wherein, the spoiler 18 comprises a first group of spoilers and a second group of spoilers. The first group of spoilers is fixedly connected to the bottom surface 35 of the first mixer 13, and the second group of spoilers is fixedly connected to the top surface 23 of the second mixer 17. The first group of spoilers and the second group of spoilers are arranged in a staggered manner relative to each other, so that when one group of spoilers moves in a circular motion relative to the other group of spoilers, the first group of spoilers and the second group of spoilers do not interfere with each other. In this case, the chance of contact between the medium to be mixed and the spoiler 18 can be further increased, and the chance of the medium to be mixed being stirred by the spoiler 18 can be further enhanced, so that the mixing effect of the medium to be mixed is better.

[0103] Among them, the inner upper surface edge 25 of the bottom shell 6 contacts the edge of the bottom surface 28 of the second mixer 17. Therefore, the inner upper surface edge 25 of the bottom shell 6 provides support for the second mixer 17, ensuring the assembly effect between the first mixer 13 and the second mixer 17. The inner upper surface center of the bottom shell 6 presents an inner cone 26 that gradually decreases from the edge to the center. The second accommodating space 30 is formed between the bottom surface 28 of the second mixer 17 and the inner upper surface of the bottom shell 6. The third through hole 27 is arranged at the center of the inner cone 26. On the second mixer 17, a plurality of sixth through holes 20 are arranged in the axial direction, and the first accommodating space 31 is connected to the second accommodating space 30 through the sixth through hole 20. In this case, the gravity effect provided by the inner cone 26 itself can be used to guide the mixed medium, so that the mixed medium can be smoothly guided to the third through hole 27, so as to be smoothly received by the receiving container.

[0104] The sixth through hole 20 is arranged on the circumference near the edge 25. In this case, the medium mixed in the first accommodating space 31 can flow from the center to the position near the edge 25 before being collected by the second accommodating space 30, further extending the flow of the mixed medium and increasing the mixing effect of the mixed medium.

[0105] The top of the rotating shaft 16 is provided with a second section shaft 2, the diameter of the second section shaft 2 is larger than the diameter of the rotating shaft 16, and the diameter of the first through hole 34 is equal to the diameter of the rotating shaft 16. In this case, the clamping force of the second section shaft 2 can achieve the assembly effect of the upper cover 1 and the first mixer 13 in the vertical direction.

[0106] In this embodiment, the orthographic projection of the upper cover 1 in the vertical direction is a first polygon, the orthographic projection of the bottom shell 6 in the vertical direction is a second polygon, and the orthographic projections of the first mixer 13 and the second mixer 17 in the vertical direction are circular. In this case, the technical problem of linkage between them due to the first mixer 13 being driven to rotate by the rotary power prime mover can be avoided.

[0107] Wherein, the rotary power driving member is a rotary motor. In this case, no manual operation is required, and the first mixer 13 can be rotated only by powering on the rotary motor, which can save human resources.

[0108] Wherein, the rotating motor is a forward and reverse rotating motor. In this case, the spoiler 18 can also realize forward and reverse rotation by setting the rotating motor forward and reverse rotation, thereby increasing the stirring effect of the spoiler 18, so that the stirring effect of the spoiler 18 on the mixed medium is better.

[0109] The upper cover 1 is also provided with a blind hole 8. In this case, a fixing member can be provided in the blind hole 8 so that the upper cover 1 can be fixed in the radial direction, thereby preventing the upper cover 1 from being rotated in conjunction with the first mixer 13 during its rotation.

[0110] The dynamic mixing device further comprises a coupling 3, one end of which is fixedly connected to the rotating shaft 16, and the other end of which is fixedly connected to the output shaft of the rotary power driving member, wherein the shape of the orthographic projection of the coupling 3 in the vertical direction is a third polygon. In this case, the linkage effect of the coupling 3 can be guaranteed.

[0111] The height of the inner side wall 24 of the bottom shell 6 is equal to the height of the mixing assembly. In this case, it can be ensured that the first mixer 13 and the second mixer 17 can be exactly accommodated in the third accommodation space 19 of the bottom shell 6 after assembly, thereby ensuring the assembly effect.

[0112] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0113] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
