Description

Technical Field

[0001] This application relates to the field of material mixing and processing equipment, and in particular to a roller-type continuous mixer device. Background Technology

[0002] Powder mixing refers to the process of mixing two or more powders in a certain proportion. To improve the strength of the final product, the more uniform the powder mixture, the better. However, manual powder mixing often results in uneven mixing and is time-consuming and labor-intensive.

[0003] To address the problem of uneven powder mixing, Chinese utility model patent CN221475607U discloses a mortar powder mixing device, including a support, a mixing cylinder, and a feed inlet. The mixing cylinder is fixedly mounted on the top of the support, and the feed inlet is located on the right side of the top of the mixing cylinder. The mixing device is positioned on the left side of the top of the support, and a feeding component is movably mounted on the right side of the bottom of the mixing cylinder. The mixing device is used to mix and stir the mortar powder, and the feeding component is used to convey the mixed material. A rotating rod, support plate, trough plate, and fixing block work together to provide adjustment and fixation functions for the conveying pipe angle, ensuring stable and reliable conveying. In summary, this mortar powder mixing device has a stable support structure, sufficient mixing space, efficient mixing and stirring, flexible material conveying, and reliable device stability, which can improve the efficiency and quality of mortar powder mixing processes. Similar to this utility model, most existing powder mixing devices mix various powders in similar proportions, and cannot fully mix powders with significantly different proportions. Summary of the Invention

[0004] Therefore, this addresses the problem in existing technologies that cannot fully mix powders with significantly different proportions and ensure that powders with smaller proportions are mixed as evenly as possible.

[0005] It is necessary to provide a roller-type continuous mixer device that can solve the above-mentioned problems in the prior art.

[0006] A roller-type continuous mixer device includes a cylinder and a mixing assembly. The cylinder is provided with an inlet and an outlet. The mixing assembly includes a primary mixer, a secondary mixer, and a tertiary mixer. The primary mixer is located inside the cylinder and near the inlet. The secondary mixer is located below the primary mixer, and the tertiary mixer is located below the secondary mixer. Each of the primary, secondary, and tertiary mixers includes a plurality of rollers. The plurality of rollers are rotatably installed inside the cylinder and are arranged alternately for graded mixing of powder materials.

[0007] Preferably, adjacent rollers rotate in opposite directions.

[0008] Preferably, the roller-type continuous mixer further includes a transport component, which includes a first powder conveyor disposed above and connected to the feed inlet.

[0009] Preferably, the transport component further includes a second powder conveyor, which is symmetrically arranged with the first powder conveyor and connected to the feed inlet.

[0010] Preferably, both the first powder conveyor and the second powder conveyor are equipped with a mixer for preliminary mixing of the powder.

[0011] Preferably, the stirrer is a long spiral stirrer.

[0012] Preferably, the transport component further includes a belt conveyor, which is disposed below the discharge port for transporting the mixed material.

[0013] Preferably, the interval between adjacent rollers is set to 4 to 7 centimeters.

[0014] The technical solution adopted in this application can achieve the following beneficial effects:

[0015] This application discloses a roller-type continuous mixer device, including a cylinder and a mixing assembly. The cylinder is provided with an inlet and an outlet. The mixing assembly includes a primary mixer, a secondary mixer, and a tertiary mixer. The primary mixer is disposed inside the cylinder and near the inlet. The secondary mixer is disposed below the primary mixer, and the tertiary mixer is disposed below the secondary mixer. Each of the primary, secondary, and tertiary mixers includes a plurality of rollers, which are rotatably installed inside the cylinder and arranged alternately for graded mixing of powder materials.

[0016] Several rollers are rotatably installed inside the cylinder. The rollers in the primary mixer, secondary mixer, and tertiary mixer rotate. When the powder comes into contact with these rollers, the rotation of the rollers applies a centrifugal force to the powder. Under the combined action of the powder's own weight and the centrifugal force of the rollers, the powder is mixed. After the powder enters the cylinder through the feed inlet, it is mixed three times in succession by the primary mixer, secondary mixer, and tertiary mixer, thus enabling the powder with significantly different proportions to be mixed evenly.

Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please refer to Figures 1 to 2 In one embodiment, the system includes a cylinder 3 and a mixing assembly. The cylinder 3 is provided with an inlet 10 and an outlet 11. The mixing assembly includes a primary mixer 4, a secondary mixer 5, and a tertiary mixer 6. The primary mixer 4 is located inside the cylinder 3 and near the inlet 10. The secondary mixer 5 is located below the primary mixer 4, and the tertiary mixer 6 is located below the secondary mixer 5. Each of the primary mixer 4, the secondary mixer 5, and the tertiary mixer 6 includes a plurality of rollers 8. The plurality of rollers 8 are rotatably installed inside the cylinder 3 and are arranged alternately for graded mixing of powders.

[0024] Specifically, the cylinder 3 is spherical, with an inlet 10 located at the top and an outlet 11 at the bottom. The spherical cylinder 3, being larger in the middle and smaller at both ends, not only provides lateral space for powder dispersion during mixing to ensure thorough mixing, but also prevents powder from splashing through the outlet 11 and inlet 10. A motor 9 is installed inside the cylinder 3, driving the rollers 8 to rotate. The speed of the motor 9 is adjustable to meet the speed requirements for mixing different powders. Different powders enter the cylinder 3 through the inlet 10, first passing through the primary mixer 4. When the powder falls due to its own weight and contacts the rollers 8, the rotation of the rollers 8 provides centrifugal force, dispersing the powder within the cylinder 3 and allowing it to mix with other powders. Powders not fully mixed in the primary mixer are further mixed by the rollers 8 in the secondary mixer. Finally, the tertiary mixer 6 significantly improves the uniformity of powder mixing. The rollers 8 of the primary mixer 4 are arranged linearly. The rollers 8 of the secondary mixer 5 are staggered with those of the primary mixer 4, and the rollers 8 of the tertiary mixer 6 are staggered with those of the secondary mixer 5. After passing through the rollers 8 of the primary mixer 4, the powder falls onto the rollers 8 of the secondary mixer 5 by its own weight, ensuring that the powder is not directly discharged from the outlet 11 after passing through the primary mixer 4 due to its own weight, thus preventing a reduction in the uniformity of the mixed powder. The staggered arrangement of the rollers 8 ensures that the powder undergoes at least two mixing processes, thereby improving the uniformity of the mixed powder.

[0025] The aforementioned roller 8 type continuous mixer device can achieve the following technical effects: a motor 9 is installed inside the cylinder 3, and the motor 9 drives the roller 8 to rotate. The speed of the motor 9 can be adjusted to meet the speed required for mixing different powders. Different powders enter the cylinder 3 through the feed inlet 10 and first pass through the primary mixer 4. When the powder falls due to its own weight and contacts the roller 8, the rotation of the roller 8 will give the powder a centrifugal force, dispersing the powder in the cylinder 3 and mixing it with other powders. Powders that are not completely mixed in the primary mixer can be mixed by the roller 8 when passing through the secondary mixer. Finally, when passing through the tertiary mixer 6, the uniformity of powder mixing is greatly improved. Even powders with large differences in proportion can be uniformly mixed after being mixed three times by the primary mixer 4, the secondary mixer 5, and the tertiary mixer 6.

[0026] In addition, this application provides some more specific implementation methods to improve the above structure.

[0027] Furthermore, to improve the uniformity of the mixed powder, the adjacent rollers 8 rotate in opposite directions.

[0028] Specifically, the rollers 8 are rotated in opposite directions. On the one hand, this can disperse the direction of powder dispersion, allowing the powder passing between two adjacent rollers 8 to be dispersed in multiple directions, thereby improving the uniformity of mixing. On the other hand, it can prevent the powder from accumulating between two adjacent rollers 8 and failing to fall, which would result in low mixing efficiency or even blockage.

[0029] Furthermore, to reduce the harm of dust to workers, the transport assembly includes a first powder conveyor 1, which is disposed above and connected to the feed inlet 10.

[0030] Specifically, since dust will be generated around the cylinder 3 during the powder mixing process, if the powder is manually added directly into the cylinder 3, on the one hand, long-term work in a dusty environment will harm the health of the workers; on the other hand, the powder will be given a small acceleration by the first powder conveyor 1, so that the powder falls into the cylinder 3 in a dispersed state, which is conducive to improving the mixing effect.

[0031] Furthermore, the transport assembly also includes a second powder conveyor 2, which is symmetrically arranged with the first powder conveyor 1 and connected to the feed inlet 10.

[0032] Specifically, the first powder conveyor 1 and the second powder conveyor 2 can simultaneously add different powders with similar proportions to the cylinder 3, which can improve the uniformity of mixing and increase the mixing efficiency to a certain extent. In addition, when the amount of powder to be mixed is large, adding powder to the cylinder 3 through the first powder conveyor 1 and the second powder conveyor 2 can effectively prevent powder from clogging the first powder conveyor 1 or the second powder conveyor 2.

[0033] Furthermore, to further improve the mixing effect, both the first powder conveyor 1 and the second powder conveyor 2 are equipped with a mixer for preliminary mixing of the powder.

[0034] Specifically, the first powder conveyor 1 and the second powder conveyor 2 are equipped with spiral agitators. For mixing multiple powders, powders with large differences in proportion are first poured into the first powder conveyor 1 and the second powder conveyor 2 for pre-mixing, so that they are mixed to a certain extent before entering the cylinder 3. Then, they are mixed by the mixing components in the cylinder 3, so that the powders with large differences in proportion can be fully and evenly mixed.

[0035] Furthermore, the stirrer is a long spiral stirrer.

[0036] Specifically, the long spiral agitator can not only improve the mixing efficiency during the mixing of powder, but also provide a guiding function for the powder, directing the powder to the end of the first powder conveyor 1 and the second powder conveyor 2, thereby ensuring that the powder can be properly added into the cylinder 3.

[0037] Furthermore, to improve work efficiency, the transport component also includes a belt conveyor 7, which is located below the discharge port 11 and is used to transport the mixed material.

[0038] Specifically, after the powder is mixed evenly, it falls through the discharge port 11 onto the belt conveyor 7 and is transported to the next process by the belt conveyor 7. The continuous movement of the belt ensures the continuous supply of material to the next process, which can ensure the continuity of the process and improve work efficiency and reduce costs to a certain extent.

[0039] Furthermore, the interval between adjacent rollers 8 is set to 4 cm to 7 cm.

[0040] Specifically, in the powder mixing process, the specifications of the powder to be mixed are generally fixed. If the distance between two adjacent rollers 8 is too small, the powder of the predetermined specifications may be crushed, resulting in the mixture not meeting the requirements of the next process. If the distance between the two rollers 8 is too large, some powder will not be able to contact the rollers 8 and will not be subjected to centrifugal force, thereby reducing the mixing effect.

[0041] When using a roller 8 type continuous mixer, powders with significantly different proportions are poured into the same conveyor for pre-mixing. The conveyor applies a small force to the powder, causing it to fall in a dispersed manner into the cylinder 3, where it contacts the rollers 8 of the primary mixer 4. The rollers 8 apply centrifugal force to the powder, increasing its dispersion and resulting in the first mixing. Then, due to its own weight, the powder falls from between two adjacent rollers 8 of the primary mixer 4 to the secondary mixer 5, where it contacts the rollers 8 for the second mixing. Finally, due to its own weight, the powder falls from between two adjacent rollers 8 of the secondary mixer 5 to the tertiary mixer 6, where it contacts the rollers 8 for the third mixing. After three mixing processes, the powder's mixability is greatly improved. The mixed powder, constrained by the cylinder 3, then falls from the outlet 11 to the belt conveyor 7, which transports it to the next process.

[0042] Through the above implementation methods, the roller 8 type continuous mixer device in the embodiments achieves at least the following technical effects:

[0043] The cylinder 3 is spherical, with a feed inlet 10 located at the top and a discharge outlet 11 at the bottom. The spherical shape of the cylinder 3, wider in the middle and narrower at both ends, not only provides lateral space for powder dispersion during mixing to ensure thorough mixing, but also prevents powder from splashing through the discharge outlet 11 and feed inlet 10. A motor 9 is installed inside the cylinder 3, driving a roller 8 to rotate. The motor 9's speed is adjustable to meet the mixing requirements of different powders. Different powders enter the cylinder 3 through the feed inlet 10, first passing through a primary mixer 4. When the powder falls due to its own weight and contacts the roller 8, the rotation of the roller 8 provides centrifugal force, dispersing the powder within the cylinder 3 and allowing it to mix with other powders. Powders not fully mixed in the primary mixer are further mixed by the roller 8 in the secondary mixer. Finally, the tertiary mixer significantly improves the uniformity of the powder mixture.

[0044] The powder is given a small acceleration as it is transported by the first powder conveyor 1 and the second powder conveyor 2, so that the powder is dispersed when it falls into the cylinder 3. The first powder conveyor 1 and the second powder conveyor 2 are equipped with spiral agitators. For the mixing of multiple powders, the powders with large differences in proportion are first poured into the conveyor for premixing, so that they are mixed to a certain extent before entering the cylinder 3. Then, they are mixed by the mixing components in the cylinder 3, so that the powders with large differences in proportion can be fully mixed evenly.

[0045] In addition, as long as the powder in the first powder conveyor 1 and the second powder conveyor 2 is continuously mixed, it can continuously provide well-uniform mixed powder, providing sufficient raw materials for the next process, reducing the time of intermittent mixing of powder, and effectively improving production efficiency.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
