Description

Technical Field

[0001] This utility model relates to the disassembly and assembly of a stirring device, specifically to a disassembly and assembly component for a magnetic stirring device. Background Technology

[0002] In stainless steel solution preparation systems, a magnetic stirrer is used to ensure stable rotation and uniform mixing of the solution. However, with increased usage time or workload, the bearing seals of the magnetic stirrer gradually wear down, leading to a decline in sealing performance and affecting the normal operation of the entire solution preparation system. Therefore, regular maintenance and replacement of the stirrer are necessary. However, due to the diverse tank sizes in the design and application of solution preparation systems (ranging from 200L to 15000L), from small preparation and intermediate product tanks to large solution storage tanks, the dimensions vary significantly. Simultaneously, the size of the manholes also varies depending on different tank design standards and intended use. This non-standardization of tanks and manholes presents the following challenges when maintaining and replacing the bearing seals of the magnetic stirrer:

[0003] 1. Limited operating space makes it difficult for staff to easily enter the tank to carry out disassembly and assembly work. In addition, the small operating space also poses risks of oxygen deficiency and damage to the inside of the tank.

[0004] 2. Incompatible standard disassembly and assembly tools. Because the bearings of the stirring device are made of silicon carbide, this material is easily damaged when disassembled using standard disassembly and assembly tools. Furthermore, it is subject to strong magnetic interference generated by the magnetic stirring device, making disassembly and assembly using standard tools extremely complicated and difficult, requiring a significant amount of maintenance time.

[0005] Therefore, how to easily disassemble and assemble the magnetic stirring device has become an important issue that urgently needs to be addressed in the current maintenance of liquid preparation systems. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a disassembly and assembly component that not only protects the tank components and personnel safety during the disassembly and assembly of the magnetic stirrer, but also makes the disassembly and assembly of the magnetic stirrer more convenient and reduces maintenance time.

[0007] The disassembly and assembly components of the magnetic stirring device provided by this utility model mainly include:

[0008] An operating lever and a stirring paddle assembly / disassembly component that can be connected to and used in conjunction with the end of the operating lever. The stirring paddle assembly / disassembly component is provided with a circular hook opposite to the blade of the stirring paddle. The stirring paddle assembly / disassembly component uses the hook to grab the shoulder of the blade of the stirring paddle and assemble / disassemble the stirring paddle on the base.

[0009] In some embodiments, the impeller assembly is made of nylon to prevent damage or scratches to the impeller surface during assembly or disassembly.

[0010] In some embodiments, at least a portion of the tail of the agitator assembly is a hollow structure, allowing the operating rod to be inserted into the tail of the agitator assembly, making it more convenient and accurate to assemble and disassemble the agitator on the base.

[0011] In a preferred embodiment of this utility model, the distal end of the operating rod is provided with a pin hole, and the tail end of the stirring paddle assembly is provided with any one of the following structures: a through groove, a through hole, a flange, or a recess, so that the operating rod can be connected and fixed to the stirring paddle assembly by means of a positioning pin, screw, or a convex-concave fit.

[0012] In some embodiments, the disassembly and assembly assembly is further provided with an extension rod, which is connected to the operating rod by a snap-fit ​​quick-release method, thereby realizing the adaptive adjustment of the operating rod length to meet the disassembly and assembly of the stirring device in tanks of different sizes.

[0013] In a preferred embodiment of this utility model, the proximal end of the extension rod may also be provided with an assist hole. When the operator operates the mixing paddle assembly and disassembly parts at a long distance, a screwdriver can be inserted into the assist hole to apply force to the extension rod, making it easier to rotate the operating rod.

[0014] In some embodiments, the disassembly assembly is further provided with a protective sleeve that houses the impeller disassembly component, allowing the impeller disassembly component to slide within the protective sleeve and enabling the hook of the impeller disassembly component to grip the shoulder of the impeller blade.

[0015] In a preferred embodiment of this utility model, the sheath is provided with guide vanes opposite to the blades of the agitator. When the agitator is installed in conjunction with the agitator assembly, the guide vanes allow the sheath to be inserted into the agitator base, guiding the male shaft of the agitator to pass through the female shaft and preventing the female shaft of the agitator from contacting the male shaft.

[0016] In a preferred embodiment of this utility model, when the sheath is inserted into the mixing paddle base, the sheath isolates the strong magnet between the mixing paddle base and the paddle blades, thereby preventing the male shaft of the mixing paddle from hitting the mixing paddle base during insertion of the female shaft due to the strong magnet between the mixing paddle base and the paddle blades, which would cause damage or scratches to the surface of the mixing paddle base or the male shaft.

[0017] In a preferred embodiment of this utility model, the sheath is made of nylon material to prevent the sheath from scratching the inner surface of the mixing paddle when it comes into contact with the inner side of the mixing paddle during the disassembly and assembly of the mixing paddle.

[0018] In some embodiments, the disassembly assembly further includes a male shaft disassembly component, which has a pair of side lugs that can hold the male shaft groove of the agitator.

[0019] In a preferred embodiment of this utility model, when the male shaft assembly / disassembly component is engaged with the male shaft groove of the agitator, the distal end of the male shaft assembly / disassembly component can abut against the male shaft sealing ring of the agitator.

[0020] In a preferred embodiment of this utility model, at least a portion of the tail of the male shaft assembly / disassembly component is a hollow structure, allowing the operating rod to be inserted into the tail of the male shaft assembly / disassembly component for long-distance operation, so that the male shaft of the agitator can be disassembled and assembled from the base of the male shaft of the agitator in a large tank over a long distance.

[0021] In a preferred embodiment of this utility model, a strong magnet is embedded in the male shaft disassembly component, which attracts the male shaft when disassembling or assembling the agitator, ensuring that the male shaft will not fall off during the disassembly or assembly process.

[0022] In some embodiments, the disassembly and assembly assembly further includes a female shaft disassembly and assembly component, the distal end of which is a socket wrench. When the socket wrench is inserted into the female shaft of the agitator, the contact surface between the socket wrench and the female shaft is tightly fitted, and the female shaft is disassembled and assembled from the agitator by rotating the socket wrench.

[0023] In a preferred embodiment of this utility model, the female shaft disassembly and assembly component is provided with an anti-detachment post. When the socket wrench is inserted into the female shaft of the agitator, the anti-detachment post cooperates with the socket wrench to clamp the female shaft, ensuring that it will not fall off during the disassembly and assembly process.

[0024] In a preferred embodiment of this utility model, the female shaft assembly / disassembly component is made of nylon material to avoid damage to the female shaft from excessively hard materials.

[0025] In a preferred embodiment of this utility model, the proximal end of the female shaft assembly / disassembly component is provided with an M6 internal thread, which fixes the female shaft assembly / disassembly component to the base plate, so that the female shaft assembly / disassembly component can easily assemble and disassemble the female shaft.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. The disassembly and assembly component of this utility model utilizes a stirring paddle disassembly and assembly part. Not only is the stirring paddle disassembly and assembly part designed with a circular hook at the far end to grab the shoulder of the stirring paddle blade on the base, but the near end is designed with a hollow structure so that the operating rod can be inserted into the near end. With the cooperation of the extension rod, the stirring paddle disassembly and assembly part can be operated at a long distance in a large tank to disassemble and assemble the stirring paddle on the base. The operator does not need to carry out disassembly and assembly work inside the tank, avoiding the risk of oxygen deficiency and damage to the inside of the tank due to the small operating space.

[0028] 2. The disassembly and assembly component of this utility model is also provided with a protective sleeve. When installing the agitator, the agitator disassembly and assembly component can be movably fitted into the protective sleeve, allowing the agitator disassembly and assembly component to slide within the protective sleeve. This not only makes it easier for the hook of the agitator disassembly and assembly component to grip the shoulder of the agitator blade, but also isolates the strong magnetism between the agitator base and the blade when the protective sleeve is inserted into the agitator base. This prevents the male shaft of the agitator from hitting the agitator base when the female shaft is inserted due to the strong magnetism between the agitator base and the blade, thus avoiding damage or scratches to the surface of the agitator base or male shaft.

[0029] 3. The protective sleeve of this utility model is also provided with guide vanes opposite to the blades of the stirring paddle. Not only can it be used to install the stirring paddle with the stirring paddle assembly, but it can also guide the male shaft of the stirring paddle to pass through the female shaft when the protective sleeve is inserted into the stirring paddle base, and isolate the female shaft of the stirring paddle from contact with the male shaft, so as to avoid the female shaft and the male shaft from colliding or rubbing against each other and damaging the surfaces of the female shaft and the male shaft.

[0030] 4. The assembly and disassembly component of this utility model is also provided with a male shaft assembly and disassembly part. The male shaft assembly and disassembly part not only uses a pair of side ears to lock the male shaft groove of the agitator, but also embeds a strong magnet in the male shaft assembly and disassembly part. When disassembling and assembling the male shaft of the agitator, the male shaft is attracted to the magnet, ensuring that the male shaft will not fall off during the disassembly and assembly process.

[0031] 5. The assembly and disassembly component of this utility model is further provided with a female shaft disassembly and assembly part. The female shaft disassembly and assembly part utilizes a socket wrench structure so that when the female shaft disassembly and assembly part is inserted into the female shaft of the agitator, it can fit tightly with the contact surface of the female shaft, so that the female shaft of the agitator can be disassembled and assembled from the base by rotation.

[0032] 6. Any one of the components of the disassembly and assembly assembly of this utility model, such as the impeller disassembly and assembly parts, the protective sleeve, or the female shaft disassembly and assembly parts, is made of nylon material. This can effectively reduce the damage caused by conventional disassembly and assembly tools using excessively hard materials, thus reducing the polishing degree of the impeller's chassis, blades, female shaft, male shaft, and other components, and affecting the impeller's performance.

[0049] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0050] Example 1

[0051] Please see Figure 1-4 The disassembly and assembly components provided in this embodiment mainly include:

[0052] The operating lever 1 and the stirring paddle assembly 2 which can be connected to and used in conjunction with the end of the operating lever 1 are provided. The stirring paddle assembly 2 is provided with a circular hook 21 opposite to the blade 311 of the stirring paddle 31. The stirring paddle assembly 2 uses the circular hook 21 to grab the shoulder of the blade 311 of the stirring paddle 31 and assemble / disassemble the stirring paddle 31 on the base 32.

[0053] The rear end of the stirring paddle assembly 2 is at least partially hollowed out, allowing the operating rod 1 to be inserted into the rear end of the stirring paddle assembly 2, making it more convenient and accurate to assemble and disassemble the stirring paddle 31 on the base 32.

[0054] The operating rod 1 has a pin hole 11 at its distal end, and the stirring paddle assembly 2 has a through groove, through hole, flange or recess at its tail, preferably a through hole 22, so that the operating rod 1 can be connected and fixed to the stirring paddle assembly 2 by means of positioning pin, screw, or convex-concave fit.

[0055] The disassembly and assembly assembly described in this embodiment is also provided with an extension rod 4. The extension rod 4 is connected and fixed to the operating rod 1 by means of a chuck quick-release method, thereby realizing the length adjustment of the operating rod 1 to meet the disassembly and assembly of the magnetic stirring device 3 in tanks of different specifications.

[0056] The extension rod 4 may also be provided with an assist hole 41 at its near end. When the operator operates the agitator assembly / disassembly part 2 at a long distance, a screwdriver can be inserted into the assist hole 41 to apply force to the extension rod 4, making it easier to rotate the operating rod 1.

[0057] In this embodiment, the operating lever 1, in conjunction with the extension lever 4, allows for long-distance operation of the agitator 31 within a large tank. The agitator 31 is disassembled and assembled on the base 32 without the operator needing to perform disassembly and assembly work inside the tank, thus avoiding the risks of oxygen deficiency and damage to the tank's interior due to the confined operating space.

[0058] Example 2

[0059] Please see Figure 5 In addition to the disassembly and assembly components provided in Embodiment 1, this embodiment also includes a protective sleeve 5 to house the agitator disassembly and assembly component 2, allowing the agitator disassembly and assembly component 2 to slide within the protective sleeve 5. This enables the hook 21 of the agitator disassembly and assembly component 2 to grip the shoulder of the blade 31 of the agitator 3, and to more conveniently install and fix it on the base of the agitator device.

[0060] The sheath 5 is provided with guide vanes 51 opposite to the blades 311 of the agitator 31. When the agitator 3 is installed with the agitator assembly 2, the guide vanes 5 allow the sheath 5 to be inserted into the chassis 312 of the agitator 3, guiding the male shaft 33 of the agitator 3 to pass through the female shaft 34, and isolating the female shaft 34 of the agitator 3 from contact with the male shaft 33, so as to avoid mutual collision or friction damage to the surfaces of the female shaft 34 and the male shaft 33.

[0061] When the sheath 5 is inserted into the base 312 of the agitator 31, the sheath 5 isolates the strong magnet between the base 312 of the agitator 31 and the blade 311, thereby preventing the male shaft 33 of the agitator 31 from hitting the base 312 of the agitator 31 and damaging or scratching the surface of the base 312, the female shaft 34 or the male shaft 33 of the agitator 31 when the female shaft 34 is inserted.

[0062] Example 3

[0063] Please see Figure 6-7 In addition to the disassembly and assembly components provided in Embodiment 1, this embodiment also includes a male shaft disassembly and assembly component 6, which is used to disassemble and assemble the male shaft 33 on the base 32.

[0064] The male shaft assembly 6 is provided with a pair of side ears 61 to hold the male shaft 33 groove 331 of the stirring device 3. When the male shaft assembly 6 holds the male shaft 33 groove 331 of the stirring paddle 3, the far end of the male shaft assembly 6 can abut against the male shaft 33 sealing ring 332 of the stirring paddle 31.

[0065] The male shaft assembly / disassembly component 6 has at least a hollow structure at its tail, allowing the operating rod 1 to be inserted into the tail of the male shaft assembly / disassembly component 6, making it more convenient and accurate to assemble and disassemble the male shaft 33 on the base 32.

[0066] In this embodiment, the operating lever 1, in conjunction with the extension lever 4, can enable long-distance operation of the male shaft assembly / disassembly component 6 on the base 32 to assemble and disassemble the male shaft 33 within a large tank. This eliminates the need for operators to perform assembly / disassembly work inside the tank, avoiding the risks of oxygen deficiency and damage to the tank's interior due to limited operating space.

[0067] In this embodiment, to prevent the male shaft 33 from falling off during disassembly and assembly, a strong magnet 62 is embedded inside the male shaft disassembly and assembly component 6. The strong magnet 52 attracts the male shaft 33 during disassembly and assembly, ensuring that the male shaft 33 will not fall off during the disassembly and assembly process.

[0068] Example 4

[0069] Please see Figure 8 In addition to the disassembly and assembly components provided in Embodiment 4, this embodiment also includes a female shaft disassembly and assembly component 7 for disassembling and assembling the female shaft 34.

[0070] The distal end of the female shaft disassembly and assembly component 7 is a socket wrench 71. When the socket wrench 71 is inserted into the female shaft 34 of the agitator 3, the contact surface of the socket wrench 71 and the female shaft 34 are tightly fitted. The socket wrench 71 is rotated to disassemble and assemble the female shaft 34 from the agitator.

[0071] In this embodiment, to prevent the female shaft 34 from falling off during disassembly and assembly, the female shaft disassembly and assembly component 7 is provided with an anti-fall-off column 72. When the socket wrench 71 is inserted into the female shaft 34 of the stirring paddle 3, the anti-fall-off column 72 cooperates with the socket wrench 71 to clamp the female shaft 34, ensuring that the female shaft 34 will not fall off during disassembly and assembly.

[0072] The female shaft assembly / disassembly component 7 is provided with an M6 internal thread 73 at its near end, which makes it easy to assemble and disassemble the female shaft 34.

[0073] Example 5

[0074] Based on the disassembly and assembly components provided in Examples 1-4, in this embodiment, any one of the components of the agitator disassembly and assembly component 2, the protective sleeve 5, or the female shaft disassembly and assembly component 7 is made of nylon material. This avoids damage or scratching of the polishing of the stainless steel surfaces of the agitator 31, base 32, female shaft 34, and male shaft 33 of the agitator device 3 during the disassembly and assembly process. It ensures that the polishing Ra value of the stainless steel surfaces of each component is usually below 0.2, so as to guarantee the hygiene and safety of the equipment.

[0075] The impeller assembly / disassembly component 2 is made of nylon to prevent damage or scratches to the surface of the impeller 31 during assembly / disassembly. The sheath 5 is also made of nylon to prevent scratches on the inner surface of the mixing device 3 when it comes into contact with the impeller 31, base 32, and inner side of the male shaft 33 during assembly / disassembly. The female shaft assembly / disassembly component 7 is made of nylon to prevent damage to the female shaft 34 from excessively hard materials.

[0076] Example 6

[0077] The steps for disassembling the magnetic stirring device inside the bioreactor tank using the disassembly and assembly components described in Examples 1-5 are as follows:

[0078] Step 1: The operator uses the circular hook 21 of the agitator assembly 2 to pass through the hollow part of the agitator 31 and grab the blade arms of the four blades 311. Then, the operator rotates the agitator assembly 2 to drive the agitator 31 to rotate counterclockwise, so that the agitator 31 is separated from the base 32, thereby disassembling the agitator 31.

[0079] The operator can insert the distal end of the operating rod 1 into the distal end of the agitator assembly 2 beforehand, and use the pin hole 11 at the distal end of the operating rod 1 to fix the agitator assembly 2 to the operating rod 1 with a pin, so that it is more convenient and accurate to assemble and disassemble the agitator 31 on the base 32.

[0080] When disassembling the agitator 31 inside a large tank, if the operating rod 1 is too short, the operator can connect the extension rod 4 using a snap-fit ​​method. This allows for adjustment of the operating rod 1's length to accommodate the disassembly and assembly of the agitator 3 inside tanks of different sizes. With the extension rod 4, the operating rod 1 can be operated from a distance within the large tank. The agitator 31 is then disassembled and assembled on the base 32 without the operator needing to perform the disassembly and assembly work inside the tank, thus avoiding the risks of oxygen deficiency and damage to the tank's interior due to limited operating space.

[0081] When the operator is operating at a distance for a long time, the agitator assembly 2 can be used to insert a screwdriver into the assist hole 41 and apply force to the extension rod 4 with the screwdriver to make it easier to rotate the operating rod 1. The agitator assembly 2 drives the agitator 3 to rotate counterclockwise, thereby removing the agitator 3 from the base 32.

[0082] Step 2: After the agitator 31 is disassembled, the operator can directly detach the female shaft 34 from the agitator 3 by rotating the blade 31 from the agitator assembly 2.

[0083] After the agitator 31 is disassembled, the operator removes the agitator 31 from the agitator disassembly and assembly part 2, and then uses the female shaft disassembly and assembly part 7. The socket wrench 71 of the female shaft disassembly and assembly part 7 is inserted into the female shaft 34 inside the agitator 31, so that the contact surface of the socket wrench 71 and the female shaft 34 are tightly fitted. Then the socket wrench 71 is rotated to remove the female shaft 34 from the agitator.

[0084] Step 3: After removing the agitator 31, use the male shaft removal and assembly part 6 to remove the male shaft 33 located on the base 32. The specific operation is as follows:

[0085] When the operator uses the male shaft assembly / disassembly piece 6 to insert the male shaft 33 located on the base 32, the lug 61 inside the male shaft assembly / disassembly piece 6 engages with the groove 331 of the male shaft 33. When the male shaft assembly / disassembly piece 6 engages with the groove 331 of the male shaft 33 of the magnetic stirring device 3, the distal end of the male shaft assembly / disassembly piece 6 can abut against the sealing ring 332 of the male shaft 33 inside the stirring paddle 31. The operator then rotates the male shaft assembly / disassembly piece 6 counterclockwise to remove the male shaft 33 from the base 32.

[0086] The strong magnet 62 inside the male shaft disassembly and assembly component 6 can fix the male shaft 33 onto the strong magnet 62 when the male shaft 33 is disassembled by the male shaft disassembly and assembly component 6, ensuring that the male shaft 33 will not fall off during the disassembly and assembly process.

[0087] Example 7

[0088] The steps for installing the components of the magnetic stirring device using the disassembly and assembly methods described in Examples 1-5 above are as follows:

[0089] Step 1: Using the female shaft assembly / disassembly piece 7, rotate the socket wrench 71 to engage the female shaft 34, which has sealing rings installed at both ends, so that the contact surfaces of the socket wrench 71 and the female shaft 34 are tightly fitted. Then, use the circular hook 21 of the impeller assembly / disassembly piece 2 to grab the blade arms of the four blades 31 and fix the impeller 31 onto the impeller assembly / disassembly piece 2. Finally, insert the socket wrench 71, which is engaged with the female shaft 34, into the female shaft mounting groove inside the impeller 31. Then, rotate the female shaft assembly / disassembly piece 7 clockwise to drive the socket wrench 71 to send the female shaft 34 into the female shaft mounting groove inside the impeller 31, and make the female shaft 34 snap into the female shaft mounting groove of the impeller 31, thereby realizing the installation of the female shaft 34 into the impeller 31.

[0090] Among them, the female shaft mounting groove of the agitator 31 of the female shaft 34 can also be directly inserted into the female shaft mounting groove of the agitator 31 of the female shaft 34 by hand.

[0091] Step 2: Insert the male shaft assembly / disassembly piece 6 into the male shaft 3, use the strong magnet 62 inside the male shaft assembly / disassembly piece 6 to attract the male shaft 33, rotate the male shaft assembly / disassembly piece 6 clockwise so that the side lug 61 of the male shaft assembly / disassembly piece 6 locks into the groove 331 of the male shaft 33, and continue to rotate the male shaft assembly / disassembly piece 6 clockwise so that the male shaft 33 is inserted into the base 32, so that the male shaft 33 is fixed on the base 32, thereby completing the installation of the male shaft 33.

[0092] When installing large tanks, if the operating lever 1 is too short, the operator can connect the extension lever 4 using a snap-fit ​​method. This allows for adjustment of the operating lever 1's length to accommodate the disassembly and assembly of the mixing device 3 within tanks of different sizes. With the extension lever 4, the operating lever 1 can be operated over long distances within the large tank. The male shaft assembly / disassembly component 6 is mounted on the base 32 to assemble and disassemble the male shaft 33, eliminating the need for the operator to perform disassembly / assembly work inside the tank. This avoids the risks of oxygen deficiency and damage to the tank's interior due to limited operating space.

[0093] Step 3: After installing the male shaft 33, insert the agitator assembly 2 into the protective sleeve 5, allowing it to slide freely within the sleeve 5. After inserting the agitator assembly 2 into the sleeve 5, clamp the guide vanes 51 of the sleeve 5 onto the outside of the base 32. Guided by the guide vanes 51, the female shaft 34 can be inserted into the male shaft 33. The operator uses the sleeve 5 to push the agitator assembly 2 towards the base 32 to insert the female shaft 34 into the male shaft 33. Then, rotating the sleeve 5 clockwise causes the female shaft 34 to rotate clockwise around the male shaft 33, locking the female shaft 34 and male shaft 33 together. Once the female shaft 34 and male shaft 33 are locked together, remove the sleeve 5.

[0094] In cases involving the installation of the agitator 31 inside a large tank, if the operating lever 1 is too short, the operator can connect the extension lever 4 using a snap-fit ​​method. With the extension lever 4, the operator can operate the agitator 31 from a long distance outside the large tank without having to perform disassembly and assembly work inside the tank. This avoids the risks of oxygen deficiency and damage to the tank's interior due to limited operating space.

[0095] In this embodiment, the magnetic stirring paddle can be installed by following the above steps using the disassembly and assembly components provided by this utility model.
