Description

Technical Field

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

[0002] When mixing liquid substances, affected by the reaction characteristics of the mixture, different substances need to be mixed quickly after being added. If the mixing speed is slow, it is easy for the substances to react when they come into contact with each other. If the materials are weighed in advance and quickly added to the mixing container for mixing, the mixing speed can be increased. However, this method is limited to substances with strong fluidity. For substances with poor fluidity, it is difficult to quickly and comprehensively add the materials to the mixing container after quantitative addition.

[0003] For example, in the case of polyurea reaction, since the reaction speed of polyurea is very fast, it needs to be weighed in advance and quickly added and mixed during mixing. However, the viscosity of polyurea resin is 600mPa·s, which has poor fluidity compared to water. Therefore, when adding a certain amount of material, it is affected by viscosity, which restricts the speed of adding the material, making it difficult to add it quickly. Summary of the invention

[0004] The object of the present invention is to provide a multi-component fast-reaction mixing device and a mixing method to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A multi-component fast-reaction mixing device comprises a cylindrical mixing container, wherein the cylindrical mixing container is composed of a plurality of spliced ​​bodies, wherein the spliced ​​bodies are composed of side wall arc plates and a fan-shaped bottom plate, wherein the outer sleeve of the cylindrical mixing container is provided with an elastic covering sleeve, wherein the elastic covering sleeve covers the circumference and the bottom surface of the cylindrical mixing container through a surrounding portion and a bottom surface portion, wherein the interior of the cylindrical mixing container is rotatably connected with a flat-plate fan blade, wherein the edge of the flat-plate fan blade contacts the inner wall of the cylindrical mixing container, and the bottom surface of the flat-plate fan blade contacts the bottom surface of the cylindrical mixing container, and the cylindrical mixing container is divided into no less than two preparation chambers by the flat-plate fan blade.

[0007] As a further solution of the present invention: storage grooves are opened on opposite sides of two adjacent fan-shaped bottom plates, an elastic member is fixedly connected between the two adjacent storage grooves, and a restraining belt is provided on the outside of the elastic covering sleeve. During mixing, the restraining belt is removed, and the elastic member pushes the fan-shaped bottom plates to open naturally to achieve the diameter expansion of the cylindrical mixing container.

[0008] As a further solution of the present invention: an external controller is arranged on the outside of the elastic covering sleeve, and the external controller includes a fixed outer cover and a gear winding shaft. The gear winding shaft rotates on the inner wall of the fixed outer cover, and a traction rope is wound on the gear winding shaft. The other end of the traction rope passes through the elastic covering sleeve and is fixedly connected to the side wall arc plate. A gear outer ring meshing with the gear winding shaft is rotated on the top of the fixed outer cover. During mixing, the gear outer ring is rotated to drive the gear winding shaft to rotate and wind up the traction rope and drive the side wall arc plate to move, thereby realizing the diameter expansion of the cylindrical mixing container.

[0009] As a further solution of the present invention: the flat-plate fan blades include a driving shaft, and the driving shaft is axially staggered with fixed blades and movable blades, the rotation angle of the movable blades is half of the angle between two adjacent fixed blades, and the angle of the movable blades is limited by a limiting portion.

[0010] As a further solution of the present invention: the fixed leaves and the movable leaves are fixed by an adhesive portion.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The bottom surface of the flat fan blade contacts the bottom surface of the cylindrical mixing container, thereby dividing the cavity of the cylindrical mixing container and separating the corresponding cavities according to the amount of mixed substances. The volume of the separated cavity can be calculated by the surface area and height, and the mass of the liquid can be obtained according to the volume and density, so as to complete the delivery in the mixing cavity. This process does not require a fast and accurate delivery instrument to achieve, increase the delivery time, and thus accurately ensure the delivery accuracy. In this process, the flat fan blade isolates the substance and does not react. When the mixing starts, the material has been delivered, so there is no need to consider the delivery speed at all. The diameter expansion of the cylindrical mixing container is used to achieve quantitative material mixing and contact simultaneously, which greatly increases the mixing speed and reduces the impact of the fast-reacting substance due to the reaction time and mixing time difference. The structure is simple and the processing cost is greatly reduced. The disposable cylindrical mixing container is used for small-volume, high-frequency, and high-accuracy material mixing experiments, which not only meets the use requirements but also eliminates the purchase cost of high-precision and fast delivery equipment.

DETAILED DESCRIPTION

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 4 :

[0026] In the present embodiment, a cylindrical mixing container 1 is included, and the cylindrical mixing container 1 is composed of a plurality of spliced ​​bodies, and the spliced ​​bodies are composed of a side wall arc plate 11 and a fan-shaped bottom plate 12. The outer sleeve of the cylindrical mixing container 1 is provided with an elastic covering sleeve 2, and the elastic covering sleeve 2 covers the circumferential side and the bottom surface of the cylindrical mixing container 1 through a surrounding portion 21 and a bottom portion 22. The interior of the cylindrical mixing container 1 is rotatably connected with a flat-plate fan blade 3, and the edge of the flat-plate fan blade 3 contacts the inner wall of the cylindrical mixing container, and the bottom surface of the flat-plate fan blade 3 contacts the bottom surface of the cylindrical mixing container. The cylindrical mixing container 1 is divided into no less than two preparation chambers 100 by the flat-plate fan blade 3.

[0027] In this embodiment, storage grooves 13 are opened on opposite sides of two adjacent fan-shaped bottom plates 12, and an elastic member 14 is fixedly connected between the two adjacent storage grooves 13. A restraining belt is provided on the outside of the elastic covering sleeve 2. During mixing, the restraining belt is removed, and the elastic member 14 pushes the fan-shaped bottom plate 12 to open naturally to achieve the diameter expansion of the cylindrical mixing container 1.

[0028] In this embodiment, an external controller 4 is arranged on the outside of the elastic covering sleeve 2, and the external controller 4 includes a fixed outer cover 41 and a gear winding shaft 42. The gear winding shaft 42 rotates on the inner wall of the fixed outer cover 41, and a traction rope 44 is wound on the gear winding shaft 42. The other end of the traction rope 44 passes through the elastic covering sleeve 2 and is fixedly connected to the side wall arc plate 11. A gear outer ring 43 meshing with the gear winding shaft 42 is rotated on the top of the fixed outer cover 41. During mixing, the rotating gear outer ring 43 drives the gear winding shaft 42 to rotate and wind up the traction rope 44 and drives the side wall arc plate 11 to move, thereby realizing the diameter expansion of the cylindrical mixing container 1.

[0029] In this embodiment, the flat fan blade 3 includes a driving shaft 31, and the driving shaft 31 is axially staggered with fixed blades 32 and movable blades 33. The rotation angle of the movable blade 33 is half of the angle between two adjacent fixed blades 32, and the angle of the movable blade 33 is limited by the limit portion 34.

[0030] In this embodiment, the fixed leaves 32 and the movable leaves 33 are fixed to each other via the adhesive portion 331 .

[0031] In this embodiment, the edges of the movable leaves 33 and the fixed leaves 32 are fixedly connected with a rubber layer.

[0032] In this embodiment, S1: the cylindrical mixing container 1 is divided into a plurality of spliced ​​bodies, an elastic covering sleeve 2 is set on the outside of the cylindrical mixing container 1, the elastic covering sleeve 2 covers the circumference and bottom of the cylindrical mixing container 1 through the surrounding part 21 and the surrounding part 22, and a flat blade 3 is selected as a rotating tool, the edge of the flat blade 3 contacts the inner wall of the cylindrical mixing container, the bottom surface of the flat blade 3 contacts the bottom surface of the cylindrical mixing container, and the cylindrical mixing container 1 is divided into at least two preparation chambers 100 by the flat blade 3. S2: the components of the mixture are independently put into the preparation chamber 100, and the amount of putting is judged according to the liquid level height of the preparation chamber 100 to achieve quantitative putting.

[0033] In this embodiment, the cylindrical mixing container 1 can be used as a disposable tool or a multiplexed tool. The disposable cylindrical mixing container 1 is made of plastic, and the purpose of the flat-plate fan blade 3 being a flat plate is to make the inner diameter of the cylindrical mixing container 1 after closing consistent with the length of the fan blade ends of the two collinear flat-plate fan blades 3. At this time, the fan blades of the flat-plate fan blade 3 are located inside the cylindrical mixing container 1, the edge of the flat-plate fan blade 3 contacts the inner wall of the cylindrical mixing container, and the bottom surface of the flat-plate fan blade 3 contacts the bottom surface of the cylindrical mixing container, thereby dividing the cavity of the cylindrical mixing container 1. The radial fan blade distribution number of the flat-plate fan blade 3 can be selected as 2, 3, 4, etc., and the corresponding cavity is separated according to the number of mixed substances. The separated cavity can calculate the volume by surface area and height, and obtain the liquid mass according to volume and density, so as to complete the delivery in the mixing chamber. This process can be realized without the need for a fast and accurate delivery instrument, and the delivery time is increased, so that the delivery accuracy can be accurately guaranteed. In this process, the flat-plate fan blade 3 isolates the substance and does not react. When mixing begins, the materials have been put in, so there is no need to consider the problem of putting in speed. The structure is simple and the processing cost is greatly reduced. The disposable cylindrical mixing container 1 is used for small-volume, high-frequency, and high-accuracy material mixing experiments, which not only meets the use requirements but also avoids the purchase cost of high-precision and fast putting equipment.

[0034] S3: Select a power source to connect with the rotating tool, the multiple spliced ​​bodies move radially outward along the cylindrical mixing container 1, increase the diameter of the cylindrical mixing container 1, the elastic covering sleeve 2 undergoes elastic deformation, the multiple preparation chambers 100 are converted into an interconnected state, and the rotating tool rotates rapidly to complete the mixing.

[0035] In this embodiment, after the cylindrical mixing container 1 expands, gaps will appear in the splicing body. If a flexible interlayer is set between two adjacent splicing bodies, the structure will be complicated and the processing cost will be high. Therefore, an elastic elastic covering sleeve 2 is used to cover the splicing body. In the initial stage, the two adjacent splicing bodies can also be fixed by adhesive bonding, and a limiting mechanism can also be set between the two adjacent splicing bodies so that the splicing bodies can only move radially outward in the same plane. It is necessary to ensure that when the splicing body is not opened, the side wall arc plate 11 forms a complete hard wall surface, and the fan-shaped bottom plate 12 forms a complete hard wall surface, so that the bottom area between each preparation cavity 100 will not be affected by other influences. The setting of the elastic covering sleeve 2 will not affect the shape of the internal cavity of the cylindrical mixing container 1. After the splicing body is opened, the elastic covering sleeve 2 can still meet the formation of a closed cylindrical cavity.

[0036] S3a: The splicing body is composed of a side wall arc plate 11 and a fan-shaped bottom plate 12. Receiving grooves 13 are opened on opposite sides of two adjacent fan-shaped bottom plates 12. An elastic member 14 is fixedly connected between the two adjacent receiving grooves 13. A restraining belt is provided on the outside of the elastic covering sleeve 2. When mixing, the restraining belt is removed, and the elastic member 14 pushes the fan-shaped bottom plate 12 to open naturally to achieve the diameter expansion of the cylindrical mixing container 1.

[0037] In this embodiment, when in use, the rotating tool is connected to the flat-plate fan blade 3 and then the flat-plate fan blade 3 is pulled upward to separate the bottom surface of the flat-plate fan blade 3 from the fan-shaped bottom plate 12, and the restraining belt on the outside of the elastic covering sleeve 2 is removed. The elastic member 14 pushes the receiving groove 13 to cause the splicing body to move radially. When the splicing body moves radially, the cylindrical mixing container 1 may deviate as a whole. However, due to the increase in the diameter of the cylindrical mixing container 1, a small amount of deviation will not affect the rotation of the flat-plate fan blade 3.

[0038] Embodiment 2:

[0039] Compared with the first embodiment, step S3a is replaced by step S3b:

[0040] In this embodiment, S3b: an external controller 4 is arranged on the outside of the elastic covering sleeve 2, and the external controller 4 includes a fixed outer cover 41 and a gear winding shaft 42. The gear winding shaft 42 rotates on the inner wall of the fixed outer cover 41, and a traction rope 44 is wound on the gear winding shaft 42. The other end of the traction rope 44 passes through the elastic covering sleeve 2 and is fixedly connected to the side wall arc plate 11. A gear outer ring 43 meshing with the gear winding shaft 42 is rotated on the top of the fixed outer cover 41. During mixing, the rotating gear outer ring 43 drives the gear winding shaft 42 to rotate and wind up the traction rope 44 and drives the side wall arc plate 11 to move, thereby realizing the diameter expansion of the cylindrical mixing container 1.

[0041] In this embodiment, the offset problem of the cylindrical mixing container 1 is solved. The cylindrical mixing container 1 is located inside the fixed outer cover 41. When expansion is required, the gear outer ring 43 is rotated to rotate the gear winding shaft 42 to drive the traction rope 44 to stretch the fan-shaped bottom plate 12 radially outward. Since the stretching speed of each traction rope 44 is uniform, the position of the cylindrical mixing container 1 is controlled to avoid or reduce position offset.

[0042] Embodiment three:

[0043] S4: The flat blade 3 includes a driving shaft 31, and the driving shaft 31 is axially staggered with fixed leaves 32 and movable leaves 33. The rotation angle of the movable leaves 33 is half of the angle between two adjacent fixed leaves 32, and the angle of the movable leaves 33 is limited by the limit portion 34. In step S4: the fixed leaves 32 and the movable leaves 33 are fixed by the bonding portion 331. After bonding, the sealing between the fixed leaves 32 and the movable leaves 33 is better. In step S4, the edges of the movable leaves 33 and the fixed leaves 32 are fixedly connected with a rubber layer. The rubber layer can ensure better fit with the inner wall of the cylindrical mixing container 1.

[0044] In this embodiment, in order to achieve the separation of the cavity, the flat fan blade 3 is a plate structure, but when the integrated plate surface is not required during mixing, please refer to Figure 3 When the movable blade 33 is a movable structure, the fixed blade 32 rotates clockwise, and the movable blade 33 is affected by the reaction force and rotates backward, so that the fan blade forms a staggered plate surface from a complete plate surface, and is limited by the limiting part 34, so that the position of the movable blade 33 is guaranteed to be fixed under the reaction condition, thereby improving the mixing effect.

[0045] Application example: In actual use, although the design of the storage groove 13 and the elastic member 14 solves the problem of smooth surface after the fan-shaped bottom plate 12 is closed, the storage groove 13 and the elastic member 14 will cause liquid residue to be difficult to collect for liquids with high viscosity, resulting in waste. Therefore, when applied to S3b, the storage groove 13 and the elastic member 14 structure are removed, and expansion is achieved through the traction rope 44. When applied to S3a, the elastic member 14 can be set at the bottom of the fan-shaped bottom plate 12, or the elastic member 14 can be extended to the bottom of the elastic covering sleeve 2, so that the fan-shaped bottom plate 12 and the elastic covering sleeve 2 are bonded and fixed to form a sealing surface, and a protrusion body is set on the bottom surface of the fan-shaped bottom plate 12 to penetrate the elastic covering sleeve 2, and the protrusion surface of the protrusion body is fixed to the elastic member 14 to solve the problem of material residue.

[0046] 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.
