Description

[0002] As an important mixing device, mixers are widely used in many industries such as chemical industry, food, and pharmaceutical industry. Their main function is to perform forced convection and uniform mixing of liquid, gas, or solid materials. According to their different structures and working principles, mixers can be divided into various types such as bottom-entry mixers and top-entry mixers. The bottom-entry mixer is usually installed at the bottom of the container, and the power is transmitted to the mixing blades through the mixing shaft, thereby realizing the mixing of materials. The top-entry mixer, on the other hand, installs the motor and the mixing shaft at the top of the container, and utilizes the action of gravity and centrifugal force to make the materials flow and mix in the container.

[0003] Although the existing mixers meet the needs of industrial production to a certain extent, there are still some deficiencies in their design and use process. First of all, the existing mixing devices usually fix the mixing frame on the mixing shaft, resulting in a bundled operation of the two. This design makes the operation process cumbersome and time-consuming when the mixing device needs to be replaced. In addition, when the existing mixer is working, the inner wall of the mixing barrel is prone to adhering materials, increasing the difficulty of subsequent cleaning, and affecting the production efficiency and the service life of the equipment.

[0004] In addition, in response to the mixing requirements of different materials, the existing technology often lacks flexibility. For example, when dealing with liquids with high viscosity or mixtures containing particulate materials, the performance of the existing mixer may not meet the actual needs, resulting in poor mixing effects and even affecting the quality of the product.

Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0022] The following refers to Figures 1 to 11 the top-entry type agitator provided by the embodiment of the present invention that is convenient for disassembly and assembly.

[0023] As Figures 1 to 11 shown, the top-entry type agitator provided by the embodiment of the present invention that is convenient for disassembly and assembly is particularly suitable for stirring liquid or solid materials, and of course it can also be applicable to stirring in other operating conditions. Specifically, the top-entry type agitator that is convenient for disassembly and assembly includes a main housing 100, a drive shaft 120, and a motor 110. The main housing 100 serves as the installation base for other parts including the drive shaft 120 and the motor 110, and other components can be directly or indirectly installed on the main housing 100 and form a relative 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, and the first axis is the central axis of the drive shaft 120.

[0024] The stirring mechanism 200 is arranged inside the main housing 100 and is used to directly stir the materials. The stirring mechanism 200 includes a movable disk 210, and the movable disk 210 is detachably connected to the drive shaft 120 and can rotate around the first axis. Specifically, a screw blade 121 is arranged on the drive shaft 120 to drive the materials to rotate, and then the rotation of the materials drives the movable disk 210 to rotate. As Figure 11As shown, a guiding structure 101 is provided on the inner wall of the main housing 100, and the guiding structure 101 is set at an inclined angle. A limiting structure 201 is fixedly arranged on the movable disk 210 and is in sliding fit with the guiding structure 101. When the movable disk 210 rotates, the limiting structure 201 slides along the guiding structure 101 to drive the movable disk 210 to move up and down, enhancing the flow of the material along the first axis, thereby enhancing the mixing degree of the material on the first axis and improving the stirring efficiency. In addition, since the driving shaft 120 and the movable disk 210 are detachably connected and can work in a relatively independent manner, the stirring device can be replaced at will, greatly reducing the difficulty of disassembly and assembly.

[0025] As Figures 5 to 9 shown, the stirring mechanism 200 includes a plurality of rotating components 300 and a plurality of storage bins 211. The plurality of storage bins 211 are circumferentially distributed on the movable disk 210 around the first axis. The rotating components 300 are arranged in the storage bins 211, and the rotating components 300 include airbag rollers 330 symmetrically arranged up and down. Before starting work, the rotating components 300 are moved along a direction perpendicular to the first axis towards the main housing 100, so that the airbag rollers 330 are in contact with the inner wall of the main housing 100. During work, 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 material. At the same time, it can also clean the material attached to the inner wall of the main housing 100 during the stirring process, reducing the cleaning difficulty and improving the cleaning efficiency.

[0026] As Figure 4 shown, the stirring mechanism 200 further includes a pneumatic pressure regulating component 230, and the pneumatic pressure regulating component 230 is connected to the rotating component 300. Specifically, when the movable disk 210 is in the first stroke, that is, when the movable disk 210 rotates and moves downward along the guiding structure 101, that is Figure 5 in the up and down direction shown in the figure, the air pressure inside the pneumatic pressure regulating component 230 increases, and the inside of the pneumatic pressure regulating component 230 is communicated with the inside of the airbag roller 330, so that the air pressure inside the airbag roller 330 increases, and then the diameter of the airbag roller 330 increases. The diameter is the dimension of the airbag roller 330 in the direction perpendicular to the first axis. Also, since the airbag roller 330 is always in contact with the inner wall of the main housing 100, the increase in the diameter of the airbag roller 330 increases the contact area with the inner wall of the main housing 100, enhancing the cleaning efficiency of the inner wall. In addition, the increase in the diameter of the airbag roller 330 increases the contact area with the material during the downward movement, which can effectively enhance the stirring force of the stirring mechanism 200 on the material, thereby pushing more liquid, forming a stronger flow, and then improving the mixing efficiency of the liquid and avoiding the accumulation caused by large pieces of material.

[0027] Furthermore, when the movable disk 210 is in the second stroke, that is, when the movable disk 210 rotates and moves upward along the guide structure 101, the air pressure inside the air pressure regulating assembly 230 is reduced, so that the diameter of the airbag roller 330 is reduced, reducing the contact area with the inner wall of the main shell 100, thereby reducing the friction resistance. Because the movable disk 210 is subject to the resistance of its own gravity during the rising process, the reduction of friction resistance makes the rising action of the movable disk 210 smoother, avoiding stagnation or increased energy consumption due to excessive resistance, and effectively reducing the wear on the inner wall, extending the service life of the equipment. In addition, the reduction in the diameter of the airbag roller 330 can more flexibly adapt to the flow characteristics of the material during the rising process, especially when processing viscous materials, it can effectively avoid the rotation obstruction caused by adhesion, and ensure the smooth operation of the agitator.

[0028] like Figure 8 and Figure 9 As shown, the diameters of the multiple groups of airbag rollers 330 are different. Specifically, before the equipment starts working, if the viscosity of the material is relatively high, the airbag roller 330 with a smaller diameter is used, and the airbag rollers 330 of other sizes are collected and stored in the storage bin 211. The airbag roller 330 with a smaller diameter has a smaller contact area with the material, which reduces the resistance of the material to the stirring mechanism 200, so that the stirring mechanism 200 can rotate at a relatively stable speed, thereby ensuring the stability of the stirring efficiency. If there are more particles in the material, the airbag roller 330 with a larger diameter is used, and the airbag rollers 330 of other sizes are collected and stored in the storage bin 211. Because during the stirring process, the centrifugal force of the rotation of the material causes the particles therein to accumulate on the inner wall of the main shell 100, and the degree of pushing intensifies as the stirring proceeds to form particle blocks 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 particle blocks, while a larger diameter airbag roller 330 can more easily pass over the pushed particle blocks, better overcome the resistance of the particles, and avoid the reduction of stirring efficiency caused by the particles.

[0029] Therefore, by using airbag rollers 330 of different sizes, an airbag roller 330 of a suitable diameter can be selected according to specific stirring requirements and the type of material, thereby optimizing the stirring effect.

[0030] Further, if Figures 5 to 6As shown, the stirring mechanism 200 further includes a rotating ring 220. An annular groove 122 is provided on the driving shaft 120. The rotating ring 220 is rotatably connected to the annular groove 122, and the annular groove 122 also prevents the rotating ring 220 from detaching from the driving shaft 120. In addition, a connecting rod 221 is fixedly provided on the rotating ring 220, and a sealing shaft 222 is fixedly provided on the connecting rod 221. The sealing shaft 222 is slidably connected to the air pressure adjusting assembly 230. On the one hand, it maintains the airtightness inside the air pressure adjusting assembly 230; on the other hand, when cleaning or replacement is required, the air pressure adjusting assembly 230 can be slid apart from the sealing shaft 222, thereby realizing the detachable connection between the rotating ring 220 and the movable disk 210, ensuring that the stirring device can be replaced at will, and greatly reducing the difficulty of disassembly and assembly.

[0031] In one embodiment, as Figures 5 to 9 shown, the rotating assembly 300 includes a limiting cylinder 301 and a mounting cylinder 302, and the limiting cylinder 301 and the mounting cylinder 302 are fixedly connected. And the rotating assembly 300 further includes a supporting assembly 320. The supporting assembly 320 includes a supporting shaft 321 and is slidably connected to the limiting cylinder 301 through the supporting shaft 321. The supporting assembly 320 further includes a plurality of supporting rollers 322, and the supporting rollers 322 are arranged inside the airbag roller 330 for fixing the airbag roller 330.

[0032] In one embodiment, as Figures 5 to 9 shown, the stirring mechanism 200 includes a first gear 232 and a second gear 233. A transmission shaft 310 is fixedly provided 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 transmission shaft 310, and the second gear 233 is rotatably connected to the mounting cylinder 302.

[0033] Furthermore, a spiral groove 313 and a sealing plate 314 are provided on the transmission shaft 310. The sealing plate 314 is slidably connected to the mounting cylinder 302 and slidably connected to the spiral groove 313. In addition, the stirring mechanism 200 includes a limiting ring 231, which is rotatably connected to the movable disk 210 and is used for fixing and pressing the first gear 232. As Figure 4 shown, the sealing plate 314, the limiting cylinder 301, the mounting cylinder 302 and the transmission shaft 310 jointly enclose a first chamber 400, and the first chamber 400 acts on the rotating assembly 300 through the supporting shaft 321.

[0034] Specifically, before working, rotate the first gear 232 to drive the second gear 233 to rotate, and then drive the transmission shaft 310 to rotate. Since the sealing plate 314 and the mounting cylinder 302 are slidably connected by splines, the rotation of the transmission shaft 310 forces the sealing plate 314 to slide downward along the spiral groove 313, that is Figure 4In the up and down directions therein. Therefore, when the sealing plate 314 slides downward, the gas inside the first chamber 400 is compressed, increasing the pressure inside the first chamber 400, thereby pushing the rotating assembly 300 to move towards the inner wall of the main housing 100, and then making the airbag roller 330 close to the inner wall of the main housing 100, and then stirring is carried out.

[0035] It can be understood that after the stirring is completed, only by rotating the first gear 232 in the reverse direction can the rotating assembly 300 be reset, and then cleaning or replacement operations can be carried out.

[0036] In one of the embodiments, as Figure 4 shown, an installation frame 311 is provided on the drive shaft 120, a transmission support 312 is provided on the installation frame 311, and the transmission support 312 is connected to the rotating assembly 300. The inside of the transmission shaft 310 is communicated with the inside of the transmission support 312 to jointly form a second chamber 500, and the air pressure regulating assembly 230 is communicated with the second chamber 500. And the support shaft 321 is slidably connected to the transmission support 312, and the airbag roller 330 is communicated with the second chamber 500 through the support shaft 321. In addition, from Figure 9 it can be seen that a plurality of ventilation holes are provided on the support assembly 320, so that the inside of the airbag roller 330 is communicated with the second chamber 500.

[0037] Furthermore, when the movable disk 210 rotates and moves downward along the guiding structure 101, that is, Figure 4 in the up and down directions therein, it drives the air pressure regulating assembly 230 to slide 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 giving an outward extrusion force to the airbag roller 330, making the diameter of the airbag roller 330 increase. When the movable disk 210 rotates and moves upward along the guiding structure 101, it drives the air pressure regulating assembly 230 to slide upward relative to the sealing shaft 222, reducing the air pressure inside the second chamber 500, and making the diameter of the airbag roller 330 decrease.

[0038] In one of the embodiments, as Figure 8 and Figure 9 shown, the rotating assembly 300 further includes a plurality of limiting blocks 315, a plurality of limiting holes 234 are provided on the movable disk 210, and the limiting holes 234 are provided at the storage bin 211. Further, the rotating assembly 300 further includes a plurality of elastic members, the elastic members are connected to the limiting blocks 315, and the limiting blocks 315 are communicated with the first chamber 400. Specifically, as Figure 4As shown, before work, after selecting an airbag roller 330 with a suitable diameter, rotate the first gear 232 to drive the second gear 233, thereby increasing the pressure inside the first chamber 400, causing the spring to compress. Then, the limit catch 315 moves outward to cooperate with the limit hole 234 to restrict the rotation of the airbag roller 330 around the central axis of the rotating assembly 300. Thus, it prevents the multiple groups of airbag rollers 330 from rotating due to being unfixed during the stirring process, thereby affecting the stirring efficiency.

[0039] In one embodiment, the top - entry stirrer that is easy to disassemble and assemble further includes a plurality of stirring mechanisms 200, which are arranged at intervals along the drive shaft 120. When the multiple groups of movable disks 210 rotate, they move up and down. This can not only clean the inner wall of the main housing 100. At the same time, the irregular up - and - down movement of two adjacent movable disks 210 causes them to approach or move away from each other, thereby enhancing the mixing degree of the liquid in the first axis direction.

[0040] The technical features of the above - mentioned embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above - mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0041] The above - described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
