Description

Technical Field

[0001] This invention relates to the field of agitator technology, and in particular to a top-entry agitator that is easy to assemble and disassemble. Background Technology

[0002] Agitators, as important mixing equipment, are widely used in various industries such as chemical, food, and pharmaceutical. Their main function is to force convection and uniformly mix liquids, gases, or solid materials. Based on their structure and working principle, agitators can be divided into several types, including bottom-entry agitators and top-entry agitators. Bottom-entry agitators are typically installed at the bottom of the container, transmitting power to the mixing blades via a stirring shaft to achieve material mixing. Top-entry agitators, on the other hand, use a motor and stirring shaft installed at the top of the container, utilizing gravity and centrifugal force to cause the materials to flow and mix within the container.

[0003] While existing agitators meet the needs of industrial production to some extent, their design and use still have some shortcomings. Firstly, existing agitators typically fix the agitator frame to the agitator shaft, resulting in a bundled operation. This design makes replacing the agitator cumbersome, time-consuming, and labor-intensive. Furthermore, during operation, material tends to adhere to the inner wall of the agitator tank, increasing the difficulty of subsequent cleaning and affecting production efficiency and equipment lifespan.

[0004] Furthermore, existing technologies often lack flexibility in meeting the mixing requirements of different materials. For example, when processing liquids with high viscosity or mixtures containing particulate materials, the performance of existing agitators may not meet the actual needs, resulting in poor mixing effects and even affecting product quality.

[0005] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] Therefore, it is necessary to provide a top-entry mixer that is easy to disassemble and install, addressing the problems of existing mixers, such as the difficulty in disassembling the mixing frame and fixed shaft, and the inability to effectively clean the material adhering to the inner wall of the mixing drum.

[0007] The above objectives are achieved through the following technical solutions:

[0008] A top-loading agitator that is easy to assemble and disassemble, comprising:

[0009] The main housing has a guide structure on its inner wall;

[0010] A drive shaft, having a first axis, is disposed inside the main housing;

[0011] A stirring mechanism, the stirring mechanism including a movable disc, the movable disc being detachably connected to the drive shaft and capable of rotating about the first axis;

[0012] The movable disc is provided with multiple circumferentially distributed rotating components, which can move along a direction perpendicular to the first axis to enhance the stirring and mixing intensity; the rotating components include multiple sets of airbag rollers arranged symmetrically above and below;

[0013] The stirring mechanism further includes a pressure regulating component connected to the rotating component. When the movable disc rotates, it can move up and down along the guide structure, having a first stroke and a second stroke. When the movable disc is in the first stroke, the pressure inside the pressure regulating component increases, causing the size of the airbag roller perpendicular to the first axis to increase. When the movable disc is in the second stroke, the pressure inside the pressure regulating component decreases, causing the size of the airbag roller perpendicular to the first axis to decrease.

[0014] The multiple sets of airbag rollers have different dimensions perpendicular to the first axis.

[0015] In one embodiment, the stirring mechanism further includes a rotating ring, which is detachably connected to the movable disc, and the air pressure regulating component is slidably connected to the rotating ring; the drive shaft is provided with an annular groove, and the rotating ring is rotatably connected to the annular groove.

[0016] In one embodiment, the rotating assembly includes a limiting cylinder and a mounting cylinder, the limiting cylinder and the mounting cylinder being fixedly connected, and the limiting cylinder being slidably connected to the airbag roller.

[0017] In one embodiment, the stirring mechanism includes a first gear and a second gear. A drive shaft is fixedly disposed inside the mounting cylinder. The first gear is connected to the movable disc, and the second gear is fixedly connected to the drive shaft. The limiting cylinder, the mounting cylinder, and the drive shaft together form a first chamber, which is connected to the rotating assembly. The first gear meshes with the second gear to increase the air pressure inside the first chamber, causing the rotating assembly to move in a direction perpendicular to the first axis.

[0018] In one embodiment, the drive shaft is provided with a spiral groove and a sealing plate, the sealing plate being slidably connected to the mounting cylinder and the spiral groove; the rotation of the drive shaft drives the sealing plate to slide along the spiral groove to change the pressure inside the first chamber.

[0019] In one embodiment, a mounting bracket is provided on the drive shaft, and a transmission bracket is provided on the mounting bracket. The transmission bracket is connected to the rotating assembly. The interior of the drive shaft and the interior of the transmission bracket communicate to form a second chamber. The air pressure regulating assembly communicates with the second chamber, and the second chamber communicates with the interior of the airbag roller.

[0020] In one embodiment, when the movable disc is within the first stroke, it increases the air pressure inside the second chamber, causing the size of the airbag roller perpendicular to the first axis to increase; when the movable disc is within the second stroke, it decreases the air pressure inside the second chamber, causing the size of the airbag roller perpendicular to the first axis to decrease.

[0021] In one embodiment, the rotating assembly includes multiple limiting blocks, and the movable disk is provided with multiple limiting holes. The limiting blocks cooperate with the limiting holes to restrict the rotation of the airbag roller around the central axis of the rotating assembly.

[0022] In one embodiment, a plurality of the stirring mechanisms are also included, the stirring mechanisms being spaced apart along the first axis.

[0023] The beneficial effects of this invention are:

[0024] This invention provides a top-entry agitator that is easy to assemble and disassemble, comprising a main housing, a drive shaft, and a stirring mechanism. The inner wall of the main housing is provided with a guide structure; the drive shaft has a first axis and is disposed inside the main housing; the stirring mechanism includes a movable disc rotatable about the first axis, detachably connected to the drive shaft; the movable disc is provided with multiple circumferentially distributed rotating components capable of moving along a direction perpendicular to the first axis; each rotating component includes multiple sets of symmetrically arranged air-cushion rollers; the stirring mechanism also includes a pressure regulating component connected to the rotating components. When the stirring mechanism rotates, it can move up and down along the guide structure, and the size of the air-cushion rollers perpendicular to the first axis is controlled by the pressure regulating component. This not only reduces the difficulty of assembly and disassembly but also enhances the mixing effect and effectively removes material adhering to the inner wall of the main housing.

[0045] The following reference Figures 1 to 11 The described embodiments of the present invention provide a top-entry agitator that is easy to assemble and disassemble.

[0046] like Figures 1 to 11As shown, the top-entry agitator provided in this embodiment of the invention, which is easy to assemble and disassemble, is particularly suitable for agitating liquid or solid materials. Of course, it can also be applied to agitation under other operating conditions. Specifically, the top-entry agitator includes a main housing 100, a drive shaft 120, and a motor 110. The main housing 100 serves as the mounting base for other components, including the drive shaft 120 and the motor 110. Other components can be directly or indirectly mounted on the main housing 100, forming a relatively integrated whole after installation. The motor 110 is fixedly connected to the drive shaft 120 and provides power for the rotation of the drive shaft 120. The first axis is the central axis of the drive shaft 120.

[0047] A stirring mechanism 200 is disposed inside the main housing 100 and is used to directly stir the materials. The stirring mechanism 200 includes a movable disc 210, which is detachably connected to the drive shaft 120 and can rotate around a first axis. Specifically, the drive shaft 120 is provided with auger blades 121 for driving the materials to rotate, which in turn drives the movable disc 210 to rotate. Figure 11 As shown, a guide structure 101 is provided on the inner wall of the main housing 100, and the guide structure 101 is set at an inclined angle. A limiting structure 201 is fixedly provided on the movable disk 210, which slides in cooperation with the guide structure 101. When the movable disk 210 rotates, the limiting structure 201 slides along the guide structure 101, causing the movable disk 210 to move up and down, enhancing the flow of materials along the first axis, thereby enhancing the mixing degree of materials on the first axis and improving the stirring efficiency. In addition, because the drive shaft 120 and the movable disk 210 are detachably connected and can operate in a relatively independent manner, the stirring device can be replaced at will, greatly reducing the difficulty of disassembly and assembly.

[0048] like Figures 5 to 9 As shown, the stirring mechanism 200 includes multiple rotating components 300 and multiple receiving chambers 211. The receiving chambers 211 are circumferentially distributed around a first axis on a movable disk 210. The rotating components 300 are disposed within the receiving chambers 211 and include symmetrically arranged airbag rollers 330. Before operation, the rotating components 300 are moved along a direction perpendicular to the first axis toward the main housing 100, so that the airbag rollers 330 contact the inner wall of the main housing 100. During operation, the rotation of the movable disk 210 drives the airbag rollers 330 to rotate, and the up-and-down movement of the movable disk 210 drives the airbag rollers 330 to move up and down along the inner wall of the main housing 100, thereby enhancing the mixing degree of the materials. Simultaneously, during the stirring process, it can also clean the materials adhering to the inner wall of the main housing 100, reducing cleaning difficulty and improving cleaning efficiency.

[0049] like Figure 4As shown, the stirring mechanism 200 also includes a pressure regulating component 230, which is connected to the rotating component 300. Specifically, when the movable disk 210 is in its first stroke, that is, when the movable disk 210 rotates and moves downward along the guide structure 101, Figure 5 As shown in the diagram, the internal air pressure of the air pressure regulating component 230 increases in the vertical direction. Since the interior of the air pressure regulating component 230 is connected to the interior of the airbag roller 330, the internal air pressure of the airbag roller 330 increases, thereby increasing the diameter of the airbag roller 330. The diameter is the dimension of the airbag roller 330 perpendicular to the first axis. Because the airbag roller 330 is always in contact with the inner wall of the main housing 100, the increased diameter of the airbag roller 330 increases the contact area with the inner wall of the main housing 100, enhancing the efficiency of cleaning the inner wall. Furthermore, the increased diameter of the airbag roller 330 increases the contact area with the material during descent, which effectively enhances the stirring force of the stirring mechanism 200 on the material, thereby pushing more liquid, forming a stronger flow, improving the mixing efficiency of the liquid, and preventing the accumulation of large pieces of material.

[0050] Furthermore, when the movable disc 210 is in its second stroke, that is, when the movable disc 210 rotates and moves upward along the guide structure 101, the internal air pressure of the air pressure regulating component 230 decreases, causing the diameter of the airbag roller 330 to decrease, reducing the contact area with the inner wall of the main housing 100, thereby reducing frictional resistance. Since the movable disc 210 experiences resistance due to its own gravity during its ascent, the reduced frictional resistance makes its upward movement smoother, avoiding jamming or increased energy consumption caused by excessive resistance, while effectively reducing wear on the inner wall and extending the equipment's service life. In addition, the reduced diameter of the airbag roller 330 allows for more flexible adaptation to the flow characteristics of materials during ascent, especially when processing viscous materials, effectively preventing rotational obstruction due to adhesion and ensuring smooth operation of the agitator.

[0051] like Figure 8 and Figure 9As shown, the multiple sets of airbag rollers 330 have different diameters. Specifically, before the equipment starts working, if the material has a high viscosity, a smaller diameter airbag roller 330 is used, while other sizes of airbag rollers 330 are collected in the storage bin 211. The smaller diameter airbag roller 330 has less contact area with the material, reducing the resistance of the material to the stirring mechanism 200, allowing the stirring mechanism 200 to rotate at a relatively stable speed, thereby ensuring the stability of the stirring efficiency. If the material contains many particles, a larger diameter airbag roller 330 is used, and similarly, other sizes of airbag rollers 330 are collected in the storage bin 211. This is because during the stirring process, the centrifugal force of the rotating material causes the particles to accumulate on the inner wall of the main shell 100, and the degree of pushing intensifies as stirring continues, forming particle clumps on the inner wall of the main shell 100. If a smaller diameter airbag roller 330 is used, it will be blocked by the pushed particles. However, a larger diameter airbag roller 330 can more easily pass over the pushed particles, better overcome the resistance of the particles, and avoid the decrease in mixing efficiency caused by the particles.

[0052] Therefore, by using airbag rollers 330 of different sizes, the appropriate diameter of airbag roller 330 can be selected according to the specific mixing requirements and the type of material, thereby optimizing the mixing effect.

[0053] Furthermore, such as Figures 5 and 6 As shown, the stirring mechanism 200 also includes a rotating ring 220. An annular groove 122 is provided on the drive shaft 120. The rotating ring 220 is rotatably connected to the annular groove 122, which also prevents the rotating ring 220 from disengaging from the drive shaft 120. Furthermore, a connecting rod 221 is fixedly mounted on the rotating ring 220, and a sealing shaft 222 is fixedly mounted on the connecting rod 221. The sealing shaft 222 is slidably connected to the pressure regulating component 230. This maintains the sealing within the pressure regulating component 230; and when cleaning or replacement is required, the pressure regulating component 230 and the sealing shaft 222 can be slidably separated, thus achieving a detachable connection between the rotating ring 220 and the movable disc 210. This ensures that the stirring device can be easily replaced, greatly reducing the difficulty of disassembly and assembly.

[0054] In one embodiment, Figures 5 to 9 As shown, the rotating assembly 300 includes a limiting cylinder 301 and a mounting cylinder 302, which are fixedly connected. The rotating assembly 300 also includes a support assembly 320, which includes a support shaft 321 and is slidably connected to the limiting cylinder 301 via the support shaft 321. The support assembly 320 also includes multiple support rollers 322, which are disposed inside the airbag roller 330 and used to fix the airbag roller 330.

[0055] In one embodiment, Figures 5 to 9As shown, the stirring mechanism 200 includes a first gear 232 and a second gear 233. A drive shaft 310 is fixedly installed inside the mounting cylinder 302. The first gear 232 is connected to the movable disk 210, the second gear 233 is fixedly connected to the drive shaft 310, and the second gear 233 is rotatably connected to the mounting cylinder 302.

[0056] Furthermore, the drive shaft 310 is provided with a spiral groove 313 and a sealing plate 314. The sealing plate 314 is slidably connected to the mounting cylinder 302, and the sealing plate 314 is slidably connected to the spiral groove 313. Additionally, the stirring mechanism 200 includes a limiting ring 231, which is rotatably connected to the movable disc 210, for fixing and clamping the first gear 232. Figure 4 As shown, the sealing plate 314, the limiting cylinder 301, the mounting cylinder 302 and the transmission shaft 310 together form the first chamber 400, and the first chamber 400 acts on the rotating assembly 300 through the support shaft 321.

[0057] Specifically, before operation, rotating the first gear 232 drives the second gear 233 to rotate, which in turn drives the transmission shaft 310 to rotate. Because the sealing plate 314 and the mounting cylinder 302 are slidably connected by a spline, the rotation of the transmission shaft 310 forces the sealing plate 314 to slide downwards along the spiral groove 313, i.e. Figure 4 The gas is compressed in the vertical direction. Therefore, when the sealing plate 314 slides downward, it compresses the gas inside the first chamber 400, increasing the pressure inside the first chamber 400. This pushes the rotating assembly 300 towards the inner wall of the main housing 100, causing the airbag roller 330 to come into contact with the inner wall of the main housing 100, and then stirring is performed.

[0058] Understandably, once the mixing is finished, simply rotating the first gear 232 in the reverse direction will reset the rotating component 300, allowing for cleaning or replacement.

[0059] In one embodiment, Figure 4 As shown, a mounting bracket 311 is provided on the drive shaft 120, and a transmission bracket 312 is provided on the mounting bracket 311. The transmission bracket 312 is connected to the rotating assembly 300. The interior of the drive shaft 310 and the interior of the transmission bracket 312 communicate to form a second chamber 500, and the air pressure regulating assembly 230 communicates with the second chamber 500. Furthermore, the support shaft 321 is slidably connected to the transmission bracket 312, and the airbag roller 330 communicates with the second chamber 500 through the support shaft 321. Additionally, by... Figure 9 It can be seen that the support component 320 has multiple ventilation holes, which allows the airbag roller 330 to communicate with the second chamber 500.

[0060] Furthermore, when the movable disk 210 rotates and moves downward along the guide structure 101, that is... Figure 4In the vertical direction, the air pressure regulating component 230 slides downward relative to the sealing shaft 222, thereby compressing the gas inside the second chamber 500, increasing the air pressure inside the second chamber 500, and thus exerting an outward squeezing force on the airbag roller 330, causing the diameter of the airbag roller 330 to increase. When the movable disk 210 rotates and moves upward along the guide structure 101, it drives the air pressure regulating component 230 to slide upward relative to the sealing shaft 222, reducing the air pressure inside the second chamber 500, and causing the diameter of the airbag roller 330 to decrease.

[0061] In one embodiment, Figure 8 and Figure 9 As shown, the rotating assembly 300 also includes multiple limiting blocks 315, and the movable disk 210 is provided with multiple limiting holes 234, which are located at the storage compartment 211. Furthermore, the rotating assembly 300 also includes multiple elastic elements, which are connected to the limiting blocks 315, and the limiting blocks 315 are in communication with the first chamber 400. Specifically, as... Figure 4 As shown, before operation, after selecting an airbag roller 330 of suitable diameter, rotating the first gear 232 drives the second gear 233, thereby increasing the pressure inside the first chamber 400 and compressing the spring. This causes the limiting block 315 to move outward and engage with the limiting hole 234, thus restricting the rotation of the airbag roller 330 around the central axis of the rotating assembly 300. This prevents multiple sets of airbag rollers 330 from rotating during stirring due to lack of fixation, which would affect stirring efficiency.

[0062] In one embodiment, the easily detachable top-entry agitator also includes multiple agitation mechanisms 200 spaced apart along the drive shaft 120. The multiple sets of movable discs 210 move up and down during rotation, not only cleaning the inner wall of the main housing 100, but also the irregular up-and-down movement of adjacent movable discs 210, causing them to move closer or further apart, thereby enhancing the mixing degree of the liquid in the first axial direction.

[0063] 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.

[0064] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
