Description

Technical Field

[0001] The invention relates to the technical field of material mixing, in particular to a multi-component fast-reaction mixing device with a fixed container. Background Art

[0002] Since polyurea reacts very quickly, it needs to be weighed in advance and quickly added and mixed during mixing. However, polyurea resin has a high viscosity and poor fluidity compared to water. Therefore, when adding a certain amount of material, it is affected by the viscosity and the speed of adding the material is restricted.

[0003] A Chinese patent discloses a multi-component fast-reaction mixing device and mixing method (CN118788171A), which uses fan blades to separate the container into independent cavities. In the mixing stage, the container is expanded so that the fan blades will not contact the side wall of the container, and the container is rotated at high speed. At this time, the material feeding amount and proportion have been adjusted in the independent cavity, so the feeding delay is basically 0, so that the mixing quality of fast-reaction materials can be effectively guaranteed. The container expansion method can choose a reusable mixing fan blade, but the expansion container is more complicated in structure and more expensive than the one-piece container. However, the advantage of the expansion container is that the fan blade has high stability, and the expansion container is controlled by an external control platform, which can achieve large-volume mixing. However, in the process of material research, small-volume mixed materials are developed, and experimental groups, control groups, reference groups, etc. are established. At this time, if the equipment of the expansion container is cited, the high R&D cost leads to low popularity. Therefore, the application cost of the method of achieving compartment mixing based on a fixed container is lower. Summary of the invention

DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 8: In this embodiment: it includes a circular container 1 and a mixing component, the mixing component divides the circular container 1 into a plurality of independent closed cavities, the mixing component is composed of a first blade module 2, a second blade module 3, and a driving central axis 5, wherein the first blade module 2 and the second blade module 3 are staggered and installed on the outside of the driving central axis 5, and the middle part of the blades of the first blade module 2 and the second blade module 3 are provided with a middle bending groove 100.

[0030] In the present embodiment: the circular container 1 adopts a fixed structure to be more stable, and the mixing assembly is composed of the first blade module 2, the second blade module 3, and the driving center shaft 5. The first blade module 2 and the second blade module 3 are alternately sleeved on the outside of the driving center shaft 5 and locked, and the first blade module 2 and the second blade module 3 can be obtained in batches through injection molds to reduce costs. The first blade module 2 and the second blade module 3 are alternately installed to adjust the height of the assembled blades according to the mixed volume, and different heights mean different volumes, so as to meet the mixed use of different volumes. After the user installs according to the needs, the mixing assembly is inserted into the circular container 1, and the blade end and the bottom surface of the blade are in contact with the inner wall and bottom surface of the circular container 1 to form a closed cavity. However, although the closure requirements of the warehouse body are met, mixing cannot be achieved at this stage, so a middle bending groove 100 is set at the blade. First, the first blade module 2 and the second blade module 3 are made of plastic and are prepared by injection molding. The setting of the middle bending groove 100 makes the strength of the middle bending groove 100 in the entire blade structure small, and the middle bending groove 100 can bend when subjected to force. When the middle of the blade is bent, the rotation is affected by the resistance of the viscous liquid. The diameter of the circle formed by the rotation of the blade is smaller than the inner diameter of the circular container 1, thereby solving the friction problem. At the same time, the blade has a wide coverage range to ensure mixing efficiency. After the blade is bent, the liquids in the adjacent bins can contact each other, thereby achieving rapid mixing.

[0031] In this embodiment: the first blade module 2 and the second blade module 3 are both detachably connected to the driving central shaft 5 through a polygonal sleeve, the number of edges of the outer wall of the polygonal sleeve is consistent with the number of blades, and the blades are fixed at the corner edges of the polygonal sleeve, and scale lines are set on the blades of the first blade module 2, the second blade module 3, and the third blade module 4.

[0032] In this embodiment: Please refer to Figure 1In the left figure, the actual divided cavity is a fan-shaped area, but part of the fan-shaped area is covered near the blade angle and the axis. In order to accurately calculate the fan-shaped area, a polygonal sleeve is provided, and the blades are fixed at the corner edges of the polygonal sleeve. At this time, a plane is formed between the two blades. Therefore, the area of ​​the closed bin is actually the fan-shaped area minus the triangular area. The area calculated by regular graphics is simpler and more accurate. At this time, scales are provided at the blades of the first blade module 2, the second blade module 3, and the third blade module 4. The liquid level height can be known through the scales, and the amount of material put in can be calculated through the surface area and the liquid level height, which increases convenience.

[0033] In this embodiment: a limiting rib 51 is fixedly connected to the driving central shaft 5, a narrow groove 21 is opened on the polygonal sleeve of the first blade module 2, and the size of the narrow groove 21 matches the limiting rib 51, and a wide groove 31 is opened on the polygonal sleeve of the second blade module 3.

[0034] In this embodiment: Please refer to Figure 1 , Figure 3 , Figure 5 The second blade module 3 and the first blade module 2 are staggered, and the blades of the second blade module 3 and the first blade module 2 are in contact and sealed with each other. During the rotation process, the materials in different chambers are not in sufficient contact after the contact and sealing. Therefore, a wide groove 31 is provided in the sleeve of the second blade module 3. After the limiting rib 51 is sleeved on the driving center shaft 5, the second blade module 3 has a certain rotation margin, so that under the action of resistance, the second blade module 3 will rotate, so that the first blade module 2 and the second blade module 3 are misaligned, so that the materials in different chambers are in quick contact, which is conducive to mixing.

[0035] In this embodiment: In this embodiment: the second blade module 3 is replaced by the third blade module 4. Based on the structure of the first blade module 2, the third blade module 4 is provided with a root bending groove 200 at the root of the blade.

[0036] In this embodiment: In order to further simplify the structure, the third blade module 4 is selected to replace the second blade module 3. The only difference between the structure of the third blade module 4 and the first blade module 2 is that the blades of the third blade module 4 are also provided with a root bending groove 200, which is arranged at the root. This method has a simpler structure. Please refer to Figure 2 and Figure 4 When the fan blades encounter resistance, the middle bending groove 100 and the root bending groove 200 will bend, but they are limited by the angle of the groove body until the groove bodies contact each other to form a fixed angle. This method can still solve the problem of uneven dispersion caused by overlapping fan blades in the vertical direction.

[0037] In this embodiment: the inner wall of the circular container 1 is fixedly connected with closing ribs 12 corresponding to the number of the mixing assembly blades, the end face of the closing rib 12 is an arc-shaped concave surface, and the end face of the blade is an arc surface.

[0038] In this embodiment: Please refer to Figure 1 and Figure 8 A middle bending groove 100 and a root bending groove 200 are provided at the fan blades. In order to make the shape of the divided bin body more standardized and realize the rapid bending of the middle bending groove 100 and the root bending groove 200 during the rotation start-up process, a closed rib 12 is provided. The end face of the fan blade is an arc surface, and the inner wall of the closed rib 12 is provided with an arc surface. At this time, the fan blade contacts the closed rib 12 to achieve sealing and limiting. However, when rotating, the fan blade will bend quickly and detach from the closed rib 12 due to the limiting influence of the closed rib 12. At this time, the middle bending groove 100 and the root bending groove 200 are in contact with each other when the fan blade just rotates, and the liquid in the bin begins to mix under the action of the fan blade.

[0039] In this embodiment: the upper and lower parts of the driving center shaft 5 are detachably connected with an upper locker 52 and a bottom locker 53. The upper locker 52 and the bottom locker 53 lock the positions of the first blade module 2, the second blade module 3, and the third blade module 4. The upper locker 52 can be fixed in the form of threads or nuts, and the bottom locker 53 can be fixed by friction with a large damping sleeve and a limiting rib 51.

[0040] In this embodiment: In this embodiment: A central hole 11 for receiving the bottom lock 53 is provided at the bottom center of the circular container 1, and the top of the central hole 11 is sealed by an elastic film. Due to the setting of the bottom lock 53, the blade below cannot achieve contact sealing with the bottom of the circular container 1, so the only change to the circular container 1 is to set a countersunk hole at the bottom of the circular container 1, which can be obtained by stamping and sealed in the hole by an elastic film. At this time, a rotatable base connected to the elastic film can also be set at the bottom of the bottom lock 53. When in use, the motor is started and the driving center shaft 5 is lifted up to the height of the bottom lock 53 to achieve mixing. The central hole 11 is closed under the action of the elastic film to avoid residual materials. An elastic telescopic column can also be buried in the central hole 11, and the telescopic column is located inside the central hole 11. The telescopic column can seal the central hole 11 without external force.

[0041] In this embodiment: the contact surfaces of the first blade module 2 and the second blade module 3, and the first blade module 2 and the third blade module 4 are sealed by sliding through the Teflon film and the rubber layer. The Teflon film is attached to one of the blade surfaces, and the rubber layer is provided on the other blade surface. The sealing can be achieved by utilizing the small sliding resistance of Teflon and combining the elastic deformation of rubber.

[0042] In the present embodiment: the middle bending groove 100 and the root bending groove 200 are filled with soft fillers; the soft fillers can be selected from sponges covered with plastic film, or soft silicone, etc., and the groove bodies are filled as long as the bending deformation of the middle bending groove 100 and the root bending groove 200 is met to avoid calculation errors.

[0043] In this embodiment: the middle bending groove 100 and the root bending groove 200 are closed by an elastic film. The elastic film is directly sleeved on the entire fan blade and wrapped around the fan blade by heat shrinking. At this time, the middle bending groove 100 and the root bending groove 200 are naturally closed. When bending, the fan blade deforms and the film also undergoes elastic deformation. When the fan blade material is hard and easy to bend and break, the film can also play a good traction role.

[0044] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
