Description

Technical Field

[0001] This application relates to the field of mixing device technology, and more particularly to a quick-release planetary high-efficiency mixing device suitable for laboratory use. Background Technology

[0002] In university laboratories, research institutions, and pilot-scale R&D settings, it is often necessary to conduct mixing experiments on different types and batches of powders, slurries, or granular materials. Such experiments usually require frequent material changes, thorough cleaning, and uniform mixing, and also require minimizing cross-contamination between batches to ensure the authenticity and repeatability of experimental data.

[0003] Most existing laboratory mixing equipment adopts a scaled-down design of industrial mixing equipment, with common solutions mainly using a fixed tank combined with a single-shaft agitator. While this type of structure can complete basic mixing operations, it still has many shortcomings in a laboratory environment. On the one hand, the tank is usually fixed in place, making disassembly cumbersome and cleaning and material replacement time-consuming, often requiring a long downtime for a thorough cleaning. On the other hand, single-shaft agitation can easily create dead zones inside the tank, resulting in insufficient agitation of viscous or granular materials and limited mixing uniformity.

[0004] Furthermore, existing devices generally lack effective vortex-breaking and flow-guiding structures and self-cleaning internal walls, making it easy for materials to adhere to the tank walls or settle at the bottom. This not only affects the mixing effect but also increases the difficulty of discharge residue and cleaning. Especially in laboratory settings, if residues cannot be quickly and thoroughly removed, cross-contamination between different formulations can easily occur, thus affecting the accuracy of experimental results. Therefore, there is an urgent need to provide a laboratory mixing device that is easy to disassemble and clean quickly, while also improving mixing uniformity, crushing effect, and discharge cleanliness.

[0005] To address the shortcomings of existing laboratory mixing equipment in terms of disassembly and assembly efficiency, mixing uniformity, wall residue control, and discharge cleanliness, it is necessary to provide a new type of laboratory mixing device that enables rapid disassembly and assembly of the mixing tank, efficient planetary mixing, synchronous crushing and turbulence, and easy thorough cleaning. Utility Model Content

[0006] This application provides a quick-disassembly planetary high-efficiency mixing device suitable for laboratories, in order to improve the technical problems of inconvenient disassembly and cleaning, poor mixing uniformity, and excessive material residue in laboratory mixing devices in related technologies.

[0007] This application provides a quick-release planetary high-efficiency mixing device suitable for laboratories, including a quick-opening ball valve for discharging materials and a supporting base.

[0008] A mixing tank, which is detachably installed within the supporting base frame;

[0009] A conical bottom is provided at the bottom of the mixing tank and is detachably and sealingly connected to the mixing tank; the quick-opening ball valve is provided at the bottom of the conical bottom.

[0010] A mixing mechanism is disposed within the mixing tank and is used for planetary mixing of materials;

[0011] The disassembly and assembly component is disposed between the support base and the mixing tank, and is used for quick positioning, locking, unlocking and disassembly of the mixing tank.

[0012] The technical solutions described above in this application embodiment have at least the following technical effects: the device, by setting a quick-detachable mixing tank and a conical bottom structure, and by setting a planetary mixing mechanism, an adjustable crushing component and a turbulence scraper component inside the tank, can meet the usage requirements of quick material replacement, full mixing, synchronous crushing and self-cleaning of the wall surface.

[0013] Furthermore, conical mating rings are respectively provided on the outer ring of the side of the conical bottom opposite to the mixing tank body, and a sealing ring is provided between the two conical mating rings. A quick-opening clamp is provided on the outer side to achieve a rapid sealing connection between the conical bottom and the mixing tank body. The combination structure of conical mating and clamp clamping not only improves the sealing stability, but also facilitates the operator to complete assembly and disassembly in a short time.

[0014] Furthermore, the assembly and disassembly components include a positioning frame at the top of the supporting base, a positioning ring at the bottom of the mixing tank, and a positioning block. The positioning block interlocks with the positioning frame, and the positioning frame contains a spring clip assembly, a locking block, and a guide rod. After the mixing tank is lowered into position, the locking block automatically engages with the locking groove under the action of the spring clip assembly, completing the positioning and locking. When disassembly is required, pulling the guide rod will allow the locking block to exit the locking groove, thus quickly unlocking the tank. This structure allows the mixing tank to be removed quickly as a whole, significantly shortening the material change and cleaning time.

[0015] Furthermore, the mixing mechanism includes a motor, a rotating shaft, a planetary carrier, rotating rods, planetary gears, a gear ring, and helical blades. After the motor drives the rotating shaft to rotate, it causes the planetary carrier to revolve. The rotating rods at both ends of the planetary carrier, while revolving with the carrier, also rotate on their own axes through the meshing of the planetary gears and the gear ring, forming a planetary motion trajectory that combines revolution and rotation. The helical blades located at the bottom of the rotating rods can tumble, shear, and agitate the material, thereby reducing mixing dead zones and improving overall mixing uniformity.

[0016] Furthermore, a synchronously rotating crushing roller is provided on the outer surface of the rotating rod. The crushing roller forms a sliding limiting engagement with the rotating rod through limiting protrusions and limiting grooves. With this structure, while performing planetary mixing, it can also crush larger particles or agglomerated materials, enabling the device to perform both mixing and crushing functions.

[0017] Furthermore, an adjusting screw is installed at the center of the bottom of the planetary support, and a connecting rod is threaded onto the adjusting screw. The connecting rod is rotatably connected to the bottom of the crushing roller. When the adjusting screw is rotated, the connecting rod can drive the two crushing rollers to rise and fall synchronously to adapt to the processing needs of materials with different quantities or particle sizes. Both ends of the connecting rod are also fixed with turbulence scrapers that fit against the inner wall of the mixing tank. As the planetary support revolves, the turbulence scrapers can both scrape off the material adhering to the inner wall and cut off and turbulent the material flow path, thereby further improving mixing efficiency and uniformity.

[0018] Furthermore, a telescopic bellows is fitted around the adjusting screw, which can extend and retract synchronously during the lifting and lowering of the connecting rod, and forms an isolation and protection for the threaded pair of the adjusting screw to reduce the risk of jamming caused by material intrusion; a metering window is provided on the front of the mixing tank, which allows the operator to observe the material quantity and crushing roller height in real time; a feed pipe and a shock-absorbing ring are provided on the top of the mixing tank, and the inner ring of the top of the support base is sealed to the outer ring of the shock-absorbing ring through a shock-absorbing pad to improve the overall airtightness.

[0019] Compared with existing technologies, this utility model has the following advantages: First, by setting a conical contact ring, a sealing ring II, a quick-opening clamp, and a positioning frame in conjunction with a locking structure, the mixing tank and the conical bottom can be quickly disassembled and automatically locked, which can significantly shorten the material replacement and cleaning time, improve experimental efficiency, and reduce the risk of cross-contamination. Second, by adopting a planetary mixing mechanism with superimposed revolution and rotation, the material agitation amplitude can be effectively increased, the stirring dead zone can be reduced, and the mixing uniformity can be improved. Third, by setting an adjustable-height crushing roller and a turbulence scraper, crushing, turbulence, and wall cleaning can be achieved simultaneously, which helps to improve the processing capacity of agglomerated materials and the cleaning effect of the inner wall. Fourth, by setting a conical bottom and a quick-opening ball valve, the discharge speed can be accelerated and the bottom residue can be reduced, which facilitates rapid emptying and thorough cleaning after the experiment.

[0028] Most existing laboratory mixing equipment adopts a scaled-down design of industrial mixing equipment, with common solutions mainly using a fixed tank combined with a single-shaft agitator. While this type of structure can complete basic mixing operations, it still has many shortcomings in a laboratory environment. On the one hand, the tank is usually fixed in place, making disassembly cumbersome and cleaning and material replacement time-consuming, often requiring a long downtime for a thorough cleaning. On the other hand, single-shaft agitation can easily create dead zones inside the tank, resulting in insufficient agitation of viscous or granular materials and limited mixing uniformity.

[0029] Furthermore, existing devices generally lack effective vortex-breaking and flow-guiding structures and self-cleaning internal walls, making it easy for materials to adhere to the tank walls or settle at the bottom. This not only affects the mixing effect but also increases the difficulty of discharge residue and cleaning. Especially in laboratory settings, if residues cannot be quickly and thoroughly removed, cross-contamination between different formulations can easily occur, thus affecting the accuracy of experimental results. Therefore, there is an urgent need to provide a laboratory mixing device that is easy to disassemble and clean quickly, while also improving mixing uniformity, crushing effect, and discharge cleanliness.

[0030] To address the shortcomings of existing laboratory mixing equipment in terms of disassembly and assembly efficiency, mixing uniformity, wall residue control, and discharge cleanliness, it is necessary to provide a new type of laboratory mixing device that enables rapid disassembly and assembly of the mixing tank, efficient planetary mixing, synchronous crushing and turbulence, and easy thorough cleaning.

[0031] Based on this, in order to improve the technical problems of inconvenient disassembly and cleaning, poor mixing uniformity, and excessive material residue in the laboratory mixing device in the related technology, the embodiments of this application provide the following solutions.

[0032] Please refer to the following: Figures 1 to 6 This application provides a quick-release planetary high-efficiency mixing device suitable for laboratory use. The device includes a support frame 221, a mixing tank 111 disposed inside the support frame 221, a conical bottom 113 disposed at the bottom of the mixing tank 111, a mixing mechanism 2 installed inside the mixing tank 111, and a disassembly / assembly assembly 22 for quick disassembly / assembly of the mixing tank 111. A feed pipe 115 is provided at the top of the mixing tank 111, and a shock-absorbing ring 116 is provided on the outer ring of the top. The inner ring of the top of the support frame 221 is sealed to the outer ring of the shock-absorbing ring 116 via a shock-absorbing pad 222, thereby creating a shock-absorbing effect during operation.

[0033] In this embodiment, the conical bottom 113 and the mixing tank 111 are connected by a quick-connect structure of conical face contact and clamp locking. Specifically, conical face contact rings 224 are fixedly connected to the outer bottom ring of the mixing tank 111 and the outer top ring of the conical bottom 113, respectively. A sealing ring 225 is provided between the two conical face contact rings 224, and a quick-opening clamp 223 is provided on its outer side. During assembly, the two conical face contact rings 224 only need to be pressed together and the quick-opening clamp 223 is put on to complete the sealing and locking. During disassembly, the conical bottom 113 and the mixing tank 111 can be separated by loosening the quick-opening clamp 223. This design can significantly reduce the difficulty of disassembly and assembly, which is conducive to rapid switching in laboratory scenarios with frequent material changes and cleaning.

[0034] In one embodiment, the cone angle of the conical contact ring 224 can be selected according to the volume of the mixing tank 111, the material sealing requirements, and the frequency of disassembly and assembly. Preferably, it is a medium cone angle structure that facilitates self-centering and tightening. In other embodiments, the quick-opening clamp 223 can also adopt a segmented quick-locking clamp, a clamping structure with a safety buckle, or a clamping structure with a quick flip-up buckle, as long as it can achieve rapid opening and closing while ensuring the tightening amount of the sealing ring 225. This setting is conducive to flexibly adjusting the connection form according to the operating habits and sealing level requirements of different laboratories, while taking into account both assembly convenience and connection reliability.

[0035] In one embodiment, to ensure that the mixing tank 111 can be quickly and stably positioned within the support frame 221, the disassembly and assembly assembly 22 is equipped with three evenly distributed positioning mechanisms. Specifically, three positioning frames 229 are mounted on the top of the support frame 221, and a positioning ring 117 is fixedly connected to the bottom of the outer ring of the mixing tank 111. Three positioning blocks 226 are provided at the bottom of the positioning ring 117, and the three positioning blocks 226 respectively engage with the interior of the three positioning frames 229. This arrangement allows the mixing tank 111 to be quickly aligned when placed into the support frame 221 and improves installation stability.

[0036] In some of the embodiments described above, to achieve automatic locking, each positioning frame 229 is provided with a spring plate group 220 and a locking block 228. Under the elastic action of the spring plate group 220, the locking block 228 is inserted into the locking groove 227 inside the positioning block 226, thereby automatically locking after the mixing tank 111 is lowered into place. This structure can reduce the manual tightening operation steps, improve assembly efficiency, and help prevent the mixing tank 111 from loosening or shifting during the mixing process.

[0037] In one embodiment, the positioning frame 229 is also equipped with a guide rod 2211, which is connected to the locking block 228. When it is necessary to disassemble the mixing tank 111, the operator only needs to pull the guide rod 2211 to drive the locking block 228 to compress the spring assembly 220 and exit the locking groove 227. Then, by releasing the quick-release clamp 223, the mixing tank 111 and the conical bottom 113 can be separated as a whole or removed separately. This design helps to shorten maintenance and cleaning time and facilitates rapid material change in laboratory settings.

[0038] In some embodiments of this application, the mixing mechanism 2 includes a motor 211 mounted on the top of the mixing tank 111, a rotating shaft 212 fixedly connected to the motor 211 and extending downwards, and a planetary support 213 fixedly connected to the bottom of the rotating shaft 212. Rotating rods 217 are rotatably connected to both ends of the bottom of the planetary support 213. Planetary gears 215 are fixedly connected to the outer surfaces of both rotating rods 217. A gear ring 216 is fixedly connected to the inner wall of the mixing tank 111, and the planetary gears 215 mesh with the inner ring of the gear ring 216. During operation, the motor 211 drives the rotating shaft 212 to rotate and causes the planetary support 213 to revolve. Simultaneously, the two rotating rods 217 rotate on their own axes under the meshing action of the planetary gears 215 and the gear ring 216, thus forming a planetary motion path with superimposed revolution and rotation. This structure allows the material to be fully agitated in both the radial and circumferential directions, which helps to reduce flow dead zones and improve mixing uniformity.

[0039] In one embodiment, spiral blades 218 are fixedly connected to the bottom of the outer surfaces of both rotating rods 217, and crushing rollers 219 are slidably connected to the outer surfaces of the two rotating rods 217 respectively. Each rotating rod 217 has a limiting protrusion 210 fixed to its outer surface for positioning, and the inner wall of the crushing roller 219 is provided with a corresponding limiting groove 2111, allowing the crushing roller 219 to maintain a restricted axial movement trajectory while rotating synchronously with the rotating rods 217. This configuration allows the device to crush agglomerated or larger particles while mixing, which is beneficial for improving mixing uniformity and the stability of subsequent experimental results.

[0040] In some of the embodiments described above in this application, to adapt to different material quantities and different crushing requirements, an adjusting screw 232 is rotatably connected to the center of the bottom of the planetary support 213. A connecting rod 231 is threaded onto the outer surface of the adjusting screw 232. The two ends of the connecting rod 231 are rotatably connected to the bottom of the outer surface of the two crushing rollers 219 via limiting rings. When the operator rotates the adjusting screw 232, the connecting rod 231 moves vertically, simultaneously adjusting the working height of the two crushing rollers 219. This arrangement allows the crushing rollers 219 to better meet the processing requirements of different material levels and different particle sizes, thus improving the applicability of the device.

[0041] In one embodiment, both ends of the two connecting rods 231 are fixedly connected to a baffle scraper 233 that fits against the inner wall of the mixing tank 111. As the baffle scraper 233 revolves with the planetary support 213, it can, on the one hand, scrape off the material adhering to the inner wall of the mixing tank 111, reducing wall residue; on the other hand, it can also create turbulence and interrupt the flow path of the material inside the tank, thereby enhancing the cross-flow and tumbling of the materials. This structure is beneficial for improving the mixing effect and also helps to reduce the cleaning difficulties caused by wall adhesion.

[0042] In some embodiments of this application, to reduce the risk of jamming caused by material entering the adjusting mechanism, two telescopic bellows 234 are sleeved on the outside of the adjusting screw 232. The opposite ends of the two telescopic bellows 234 are fixed to the top and bottom of the connecting rod 231, respectively. The top of the top telescopic bellows 234 is rotatably connected to the bottom of the planetary support 213, and the bottom of the bottom telescopic bellows 234 is rotatably connected to the bottom convex edge of the adjusting screw 232. As the connecting rod 231 rises and falls, the telescopic bellows 234 expands and contracts synchronously, thereby providing a protective covering for the threaded joint of the adjusting screw 232. This arrangement reduces the risk of blockage after fine materials enter the screw joint and helps improve the stability of the adjusting process.

[0043] In one embodiment, a metering window 112 is provided on the front of the mixing tank 111, allowing the operator to observe the amount of material and the height of the crushing roller 219, thus enabling timely monitoring of the internal state during feeding or adjustment. After mixing, the material can converge to the conical bottom 113 under gravity and be quickly discharged through a quick-opening ball valve 114 located at the bottom of the conical bottom 113. Preferably, the cone angle of the conical bottom 113 can be set to 30° to 45°, for example, 35°, to balance material collection efficiency and discharge smoothness. This structure effectively reduces bottom residue, improves discharge speed, and facilitates thorough subsequent cleaning.

[0044] In one embodiment, the assembly process of the mixing tank 111 and the supporting base 221 can be carried out in the following order: First, the cleaned conical bottom 113 is aligned and fitted with the lower end of the mixing tank 111 through the conical face contact ring 224, and the sealing ring 225 is placed between the two conical face contact rings 224; then, the quick-release clamp 223 is sleeved on the outside of the two conical face contact rings 224 and locked, so that the conical bottom 113 and the mixing tank 111 form a reliable sealed connection; then the assembled mixing tank 111 is lifted as a whole or manually. Lift the container above the support base 221, align the three positioning blocks 226 with the openings of the three positioning frames 229, and slowly lower them. After the positioning blocks 226 enter the positioning frames 229, the locking blocks 228 automatically engage with the locking grooves 227 under the action of the spring plate group 220, thereby completing the quick positioning and locking between the mixing tank 111 and the support base 221. Finally, check the fit between the shock-absorbing ring 116 and the shock-absorbing pad 222, and confirm that the feed pipe 115, metering window 112, and quick-opening ball valve 114 are in normal working positions.

[0045] In some embodiments of this application, the use of the device may include several stages: material preparation, mixing and crushing, state observation, material discharge and collection, and shutdown cleaning. Specifically, the operator can first add the powder, granules, slurry, or liquid-solid mixture to be mixed into the mixing tank 111 through the feed pipe 115, and pre-adjust the height of the crushing roller 219 according to the material characteristics. After the material is added, the motor 211 is started, driving the rotating shaft 212, planetary support 213, and rotating rod 217 to perform a combined revolution and rotation motion. The spiral blades 218 lift and tumble the material, the crushing roller 219 crushes and shears larger agglomerates, and the turbulence scraper 233 continuously scrapes off the material adhering to the inner wall and changes the flow field distribution inside the tank. During the mixing process, the operator can observe the material tumbling state, material level, and the corresponding position of the crushing roller 219 through the metering window 112, and adjust the motor speed or the position of the lead screw 232 in a timely manner according to the observation results. Once the mixture reaches the predetermined uniformity, stop motor 211, open quick-opening ball valve 114, allowing the material to collect along the conical bottom 113 and be quickly discharged into the receiving container. This process simultaneously considers mixing, crushing, turbulence, wall scraping, and discharge, which helps improve the continuity of the experimental process and the stability of the results.

[0046] In one embodiment, for dry powder materials with good flowability, the crushing roller 219 can be adjusted to a higher position, and the linear velocity of the spiral blades 218 can be appropriately increased to enhance the upward scattering effect and the overall tumbling range. For paste-like or slurry-like materials with high viscosity, the crushing roller 219 can be adjusted to a lower working position, and preferably, spiral blades 218 with a smaller pitch and flexible wall-mounted turbulence scrapers 233 can be used to enhance the ability to crush and peel off agglomerates and wall-attached layers. For fragile particles or coated granular materials, the rotation speed of the rotor 217 can be reduced, and the surface of the crushing roller 219 can be set as a rounded, pressure-relieving structure to avoid excessive shearing that could damage the particle structure. By adjusting the mixing parameters and contact component forms for different material properties, the device can more flexibly adapt to the needs of multi-category, small-batch, and high-frequency switching in the laboratory.

[0047] In some of the embodiments described above, the disassembly and cleaning process after mixing is also relatively simple. The operator can first confirm that the motor 211 has completely stopped operating and open the quick-opening ball valve 114 to the empty state, allowing the remaining material to be basically discharged. Then, loosen the quick-opening clamp 223 and pull the guide rods 2211 on each positioning frame 229 to disengage the locking block 228 from the locking groove 227. Then, lift the mixing tank 111 entirely from the support base 221. Afterward, the conical bottom 113 can be separated from the mixing tank 111, and the inner cavity of the conical bottom 113, the inner wall of the mixing tank 111, the spiral blades 218, the crushing roller 219, the turbulence scraper 233, and the outer surface of the telescopic bellows 234 can be rinsed, wiped, or soaked for cleaning. For scenarios requiring a higher level of cleanliness, the quick-opening ball valve 114, quick-opening clamp 223, and replaceable scraper head can be further removed for separate disinfection or sterilization. Since the main contact parts of this device can be quickly exposed or removed, it can significantly reduce the problem of difficult cleaning of the dead corners inside traditional fixed tank equipment, which helps to reduce residues and reduce the risk of cross-contamination.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
