Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, and more specifically, to a desktop stirring device. Background Technology

[0002] In laboratory research and development, stirring is a core step in material mixing and reaction process control, and traditional benchtop mixers have become common equipment in laboratories. However, existing technologies still have many shortcomings: Traditional desktop stirring devices have limited detection functions, mostly only able to drive the stirring action, and cannot sense key physicochemical parameters of materials in real time (such as viscosity, temperature, chemical component concentration, etc.). This results in the stirring process being in a "black box" state, requiring researchers to frequently interrupt experiments for offline sampling and analysis, which is not only inefficient but may also disrupt the continuity of the reaction, introduce contamination, or lead to distorted detection results.

[0003] While some improved stirring devices integrate a single sensor (such as a viscosity sensor), they lack the ability to monitor multiple parameters simultaneously. Furthermore, their power transmission and sealing structures are poorly designed, posing a risk of leakage and contamination, making them unsuitable for experiments involving sterile or corrosive materials. Additionally, the existing devices often have fixed support structures, preventing flexible adjustment of the stirring module's position based on the height of the experimental container, resulting in poor adaptability. The connection between the stirring shaft and the power unit is complex, with chaotic wiring, affecting the device's stability and ease of operation.

[0004] Furthermore, traditional devices lack an intelligent control mechanism that links with the detection module, making it impossible to automatically adjust stirring parameters based on material conditions. Reliance on manual operation leads to poor experimental repeatability, failing to meet the demands of high-end laboratory research for process visualization, data quantification, and operational automation. Therefore, there is an urgent need for a desktop stirring device with optimized structure, integrated functions, strong adaptability, and reliable sealing to overcome the shortcomings of existing technologies.

[0026] The following is combined with Figures 1-3 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] This invention provides a desktop mixing device, including a base 1, a support structure, a mixing power device 4, a control module 5, a detection module, and a mixing module; the mixing module includes a mixing shaft 9 and a mixing blade 11; one end of the support structure is disposed on the base 1, and the mixing power device 4 and the control module are both disposed on the other end of the support structure; the detection module is disposed on the mixing module, and the control module 5 is signal-connected to the detection module; the mixing blade 11 is connected to the mixing power device 4 through the mixing shaft 9.

[0028] In this embodiment, the base 1 serves as the supporting foundation of the entire device and adopts a flat plate structure. By increasing the contact area with the tabletop, the upper load is distributed, avoiding excessive local stress that could cause vibration or tilting during device operation. The base 1 has a preset mounting position that precisely matches one end of the support structure, such as threaded holes or snap-fit ​​slots, to ensure the rigidity and detachability of the connection. This facilitates transportation and storage while ensuring structural stability during use.

[0029] In this embodiment, the support structure adopts a rigid rod or frame structure, and its lower end is fixedly connected to the base 1 to directly transmit the weight of the stirring power device 4 and the control module 5 to the base 1, so as to avoid the bending and deformation of the support structure itself; its upper end supports the stirring power device 4 and the control module 5 by clamping or bolt fixing.

[0030] In this embodiment, the stirring module consists of a stirring shaft 9 and a stirring blade 11. The stirring shaft 9 adopts a rigid slender rod structure, and its two ends are detachably connected to the stirring power device 4 and the stirring blade 11, respectively. Different types of blades can be replaced according to the material characteristics, such as anchor type and propeller type. The structure of the stirring blade 11 is perpendicular to the stirring shaft 9 or at a preset angle to ensure that it can fully contact the material when rotating.

[0031] In this embodiment, the detection module is integrated into a preset mounting position of the stirring module, such as the middle of the stirring shaft 9 or the root of the stirring blade 11, to ensure that the sensing element can directly or indirectly contact the material and reduce parameter transmission errors.

[0032] In this embodiment, the signal connection between the control module 5 and the detection module is achieved through wires or built-in circuits, and the structure reserves a signal interface to ensure the reliability and maintainability of the connection.

[0033] In this embodiment, the components are connected by modular quick-change interfaces, allowing users to replace the stirring blades or functional accessories in seconds. This enables a single host unit to handle various mixing tasks, from low-viscosity liquids to high-viscosity slurries, and allows for future expansion with new sensing functions, maximizing investment value.

[0034] In this embodiment, the stirring power device 4 is an electric motor.

[0035] Specifically, in this embodiment, the output shaft of the motor is connected to the stirring shaft 9, driving the stirring shaft 9 and the stirring blades provided on the stirring shaft 9 to rotate.

[0036] Installation Phase: First, select a flat, dry experimental table as the placement surface, remove any debris, and ensure that the base 1 is in flat contact with the table to avoid vibration during operation due to uneven contact surfaces. Align one end of the support structure with the preset mounting position on the base 1 and connect it using threaded connections, snap-fit ​​fixings, or bolt tightening. When tightening, ensure that the support structure is perpendicular to the base 1 without any tilting deviation. Install the stirring power unit 4 and control module 5 into place using the fixing component 3 at the other end of the support structure. Adjust their positions so that the output shaft of the stirring power unit 4 is coaxially aligned with the connection end of the stirring shaft 9. Adjust the signal of the control module 5. The interface should be oriented for easy wiring; the detection module should be installed in a preset position on the mixing module, such as the mounting groove in the middle of the mixing shaft 9 or the fixing hole at the root of the mixing blade 11, to ensure that the sensing element of the detection module can directly contact or approach the material, avoiding damage from the material flow generated when the mixing blade 11 rotates; the signal interface between the detection module and the control module 5 should be connected by wires, ensuring that the wires are securely connected without any risk of loosening or short circuits. If a wireless connection is used, module pairing should be completed; finally, the mixing blade 11 should be assembled into place through the connection structure at the lower end of the mixing shaft 9, ensuring that the mixing blade 11 is securely installed without any shaking.

[0037] Debugging phase: Start control module 5 and check if the detection module outputs a signal normally. For example, observe whether there are parameter values ​​displayed on the display screen of control module 5 to confirm that the signal transmission link is smooth. Start stirring power device 4 and test the rotation status of stirring shaft 9 and stirring blade 11. Observe whether there are any abnormal noises, excessive vibrations or eccentric rotation. If there is a deviation, adjust the installation position of the support structure or stirring module until the rotation is stable. Place the empty experimental container on the base 1 so that the stirring blade 11 extends into the container to the preset depth, ensuring that the stirring blade 11 does not contact the inner wall of the container.

[0038] Operation Phase: Pour the material to be stirred into the experimental container, ensuring that the liquid level covers the sensing element of the detection module or reaches the preset detection height; set the stirring parameters, such as rotation speed and stirring time, through the control module 5, and start the stirring program. The stirring power unit 4 drives the stirring shaft 9 and stirring blades 11 to rotate, and the material stirring begins; during operation, the detection module collects relevant material parameters in real time, such as viscosity, temperature, and other basic parameters, and transmits them to the control module 5. The control module 5 displays the parameter data in real time, and the experimenter can observe the parameter changes during the stirring process through the display screen without interrupting the experiment for offline sampling; if the experiment requires data recording, the parameter data can be exported through the storage function of the control module 5 or through an external device for subsequent experimental analysis.

[0039] Maintenance Phase: After the experiment, turn off the power to the device. After the stirring blade 11 has completely stopped rotating, disassemble the stirring blade 11 and the detection module, and clean them with a suitable cleaning agent to avoid material residue affecting the next use; check whether the connections of each component are loose, and tighten them in time if they are loose; clean the debris on the surface of the base 1 and the support structure, and store them in a dry and ventilated laboratory storage rack to avoid corrosion of the components due to the humid environment; regularly check whether the signal connection wires are damaged, whether the stirring shaft 9 is bent or deformed, and whether the detection module can output signals normally. Replace or repair it in time if any problems are found.

[0040] In an optional embodiment, the detection module includes a torque sensor 10, which is disposed between the stirring power unit 4 and the stirring module.

[0041] In this embodiment, the torque sensor 10, as the core component of the detection module, is installed between the stirring power unit 4 and the stirring module. Specifically, the input end of the torque sensor 10 and the output end of the stirring power unit 4 are rigidly connected, such as by flange connection or keyway fit, to ensure that the torque output by the power unit can be fully transmitted to the sensor, avoiding torque loss or detection deviation due to connection gaps. The output end of the sensor is rigidly connected to the upper end of the stirring shaft 9 of the stirring module, so that the torque transmitted to the material by the stirring shaft 9 is consistent with the torque detected by the sensor. The overall structure of the torque sensor 10 adapts to the compact layout of the device. Its shape is cylindrical or annular, and its outer diameter matches the diameter of the output end of the stirring power unit 4 and the upper end of the stirring shaft 9, avoiding structural interference due to excessive size. At the same time, the sensor housing is provided with fixing lugs, which are bolted to the support structure or the housing of the stirring power unit 4 for auxiliary fixation, preventing the sensor from shifting due to vibration during stirring and ensuring detection stability.

[0042] Specifically, in this embodiment, the torque sensor 10 is a strain gauge, which is directly attached to the sensitive area inside the hollow spindle.

[0043] In this embodiment, the torque sensor 10 directly senses the resistance of the blade, avoiding the transmission loss and friction interference caused by the traditional indirect measurement through motor current. The measurement results truly reflect the rheological state of the material, and the data is accurate and reliable.

[0044] In an optional embodiment, the detection module further includes a temperature sensor 12; the temperature sensor 12 is located at the end of the stirring module away from the stirring power device 4.

[0045] In this embodiment, the temperature sensor 12 is installed at the end of the stirring module away from the stirring power device 4, that is, at the lower end of the stirring shaft 9 or on the stirring blade 11. This position is the core area where the stirring blade 11 directly interacts with the material. Installing the temperature sensor 12 here can bring it as close to the material as possible and avoid temperature detection delay or deviation due to excessive distance.

[0046] In this embodiment, the temperature sensor 12 is embedded. A mounting hole is pre-set at the lower end of the stirring shaft 9 or the root of the stirring blade 11. The diameter of the mounting hole is precisely matched with the outer diameter of the temperature sensor 12. The sensor probe is embedded in the hole and extends out a preset length. The sensor body is fixed to the mounting hole by threads or buckles. The outer shell is flush with the surface of the stirring shaft 9 or the stirring blade 11 to avoid additional friction or resistance with the material during rotation.

[0047] In this embodiment, the wiring of the temperature sensor 12 extends from inside the mounting hole, is laid out along the outside, inside or a preset groove of the stirring shaft 9, and is finally connected to the control module 5.

[0048] Torque sensor 10 focuses on the physical parameters of the power transmission path, while temperature sensor 12 focuses on the thermal parameters of the material action area. The installation positions of the two do not interfere with each other and correspond to different characteristic dimensions of the material. Through spatial differentiation, multi-parameter synchronous detection is achieved without changing the overall compact structure of the device. At the same time, the embedded installation ensures that the sensors are firmly fixed and can withstand the impact and vibration of the material during the stirring process.

[0049] In an optional embodiment, the detection module further includes a spectral probe 13; the spectral probe 13 is disposed at the end of the stirring module away from the stirring power device 4.

[0050] In this embodiment, the spectral probe 13 is installed at the end of the stirring module away from the stirring power device 4, that is, at the lower end of the stirring shaft 9 or on the stirring blade 11.

[0051] In this embodiment, the detection module directly integrates the torque sensor 10, temperature sensor 12, and spectral probe 13 into the detection probe and contacts the material, so that all measurements are performed in situ within the reaction vessel during the stirring process, without the need for sampling, thus obtaining the most accurate process data.

[0052] In an optional embodiment, the stirring power unit 4 and the stirring module also have a magnetic coupling transmission mechanism.

[0053] In this embodiment, the magnetic coupling transmission mechanism is set between the stirring power device 4 and the stirring module, replacing the traditional direct mechanical connection. The input end and the output end transmit power through magnetic field force rather than mechanical contact, so an isolation space can be reserved between the two.

[0054] In an optional embodiment, the magnetic coupling transmission mechanism includes an outer magnetic rotor 6 and an inner magnetic rotor 8; the outer magnetic rotor 6 is connected to the output end of the stirring power device 4; and the inner magnetic rotor 8 is connected to the end of the stirring shaft 9.

[0055] In this embodiment, the outer magnetic rotor 6 has a ring-shaped structure. Its inner wall or end face has several permanent magnets arranged alternately with N and S poles. These permanent magnets are fixed to the rotor base using adhesive or mechanical fastening. The rotor base has a central shaft hole, which is tightly connected to the output end of the stirring power device 4 via key connections, interference fits, or set screws, ensuring that the torque output by the power device is fully transmitted to the outer magnetic rotor 6 without relative slippage. The inner magnetic rotor 8 has a structure adapted to the outer magnetic rotor 6, being cylindrical or ring-shaped. Its outer wall or end face also has permanent magnets arranged alternately with N and S poles. The number and polarity of the permanent magnets correspond completely to those of the outer magnetic rotor 6. For example, if the outer magnetic rotor 6 has 8 permanent magnets, the inner magnetic rotor 8 also has 8, with corresponding polarities. The rotor base has a central shaft hole, which is fixed to the end of the stirring shaft 9 using the same rigid connection method, ensuring that the inner magnetic rotor 8 can drive the stirring shaft 9 to rotate synchronously.

[0056] The outer magnetic rotor 6 and the inner magnetic rotor 8 are designed to be coaxially aligned, meaning that their axes are completely overlapped. The outer magnetic rotor 6 is fitted outside the inner magnetic rotor 8 (or set opposite to it), with a fixed gap reserved between them. The size of the gap is set according to the magnetic field strength of the permanent magnet and the required torque. If the gap is too small, it will easily cause the magnetic rotors to collide. If the gap is too large, the magnetic force will be weakened and the power transmission efficiency will decrease.

[0057] The permanent magnets of the outer magnetic rotor 6 and the inner magnetic rotor 8 have corresponding polarities. The magnetic field force generated during rotation can form a stable magnetic torque, ensuring that the two rotate synchronously without speed difference. At the same time, the modular magnetic rotor structure is easy to replace and maintain. If the magnetism of the permanent magnet decays, the magnetic rotor can be replaced separately without replacing the entire transmission mechanism, further improving the stability and reliability of power transmission.

[0058] In an optional embodiment, a static sealing isolation cover 7 is provided between the outer magnetic rotor 6 and the inner magnetic rotor 8.

[0059] In this embodiment, the static sealing isolation cover 7 is set in the gap area between the outer magnetic rotor 6 and the inner magnetic rotor 8. It is a cylindrical thin-walled structure and is made of non-magnetic, high-strength material. The non-magnetic material ensures that the magnetic field can penetrate the isolation cover and be transmitted, avoiding the magnetic field being shielded. The high-strength material ensures that it can withstand the pressure of the material and the impact of the stirring process. The thin-walled structure reduces the distance of magnetic field transmission and ensures that the magnetic torque does not decay.

[0060] The static sealing isolation cover 7 is cylindrical, and its edge is fixed and sealed to the housing or support structure of the stirring power device 4 by welding, flange connection or sealant. The sealing connection ensures no gaps, completely enclosing the outer magnetic rotor 6 in the closed space formed by the isolation cover, and completely separating the atmospheric environment where the stirring power device 4 is located from the material environment where the stirring module is located.

[0061] The static sealing cover and isolation cover completely eliminate the leakage risk caused by the dynamic sealing of the stirring shaft 9, ensuring the sterility, leakage-free and pollution-free nature of the reaction system, and meeting the requirements of demanding applications such as biopharmaceuticals and sterile materials.

[0062] In an optional embodiment, the stirring shaft 9 has a hollow structure, and the circuitry of the detection module is installed inside.

[0063] In this embodiment, the stirring shaft 9 is a hollow cylinder, and the material is selected from high-strength metals such as stainless steel and alloy steel to ensure sufficient rigidity and torque transmission capacity, and to avoid insufficient strength and bending deformation during rotation due to the hollow structure.

[0064] The inner diameter of the hollow channel is set according to the wiring requirements. It must be able to accommodate all the wiring of the detection module and leave a certain margin to facilitate wiring installation and maintenance. The hollow channel runs through the entire length of the stirring shaft 9 and is open at both ends. The upper opening is close to the connection between the stirring power unit 4 and the stirring module, and the lower opening is close to the installation end of the stirring blade 11, ensuring that the wiring can pass through from one end and out from the other end, connecting the detection module and the control module 5.

[0065] This configuration allows the wiring to be completely hidden inside the stirring shaft 9, avoiding problems such as wire tangling, wear and tear from materials, and corrosion from corrosive materials that are caused by traditional external wiring, thus greatly improving the service life of the wiring and the stability of signal transmission.

[0066] In an optional embodiment, the support structure includes a vertical support rod 2 and a fixing component 3; one end of the fixing component 3 is connected to the vertical support rod 2, and the other end is fixedly connected to the stirring power device 4 and the control module 5.

[0067] In this embodiment, the vertical support rod 2 is a rigid rod structure made of high-strength metal or carbon fiber composite material to ensure sufficient compressive strength and bending stiffness, preventing bending deformation due to upper load. The lower end of the support rod is rigidly connected to the base 1, such as by threaded connection, welding, or expansion bolt fastening. The connection structure ensures that the support rod is perpendicular to the surface of the base 1 without tilting deviation. The structural logic is to evenly transfer the weight of the upper load to the base 1 through the support rod, and then distribute it from the base 1 to the experimental table.

[0068] One end of the fixing component 3 is connected to the vertical support rod 2 via a locking mechanism, such as a locking bolt, a buckle, or a tightening sleeve. The locking mechanism can fix the position of the fixing component 3 on the support rod while ensuring the rigidity of the connection. The other end is provided with an installation structure adapted to the stirring power device 4 and the control module 5, such as a clamping groove, bolt holes, or positioning pins. The dimensions of the installation structure are precisely matched with the housing of the stirring power device 4 and the outer shell of the control module 5 to ensure that both can be installed securely without loosening or displacement.

[0069] The overall structure of the fixed component 3 is symmetrically arranged, that is, the installation positions of the stirring power device 4 and the control module 5 are symmetrical about the axis of the vertical support rod 2. Its structural logic is to balance the center of gravity of the upper load, so that the overall center of gravity falls on the axis of the vertical support rod 2, avoiding the support rod from bearing additional bending moment due to the offset of the center of gravity, improving structural stability, and preventing vibration caused by the offset of the center of gravity during the stirring process.

[0070] In an optional embodiment, the height of the fixing component 3 on the vertical support rod 2 is adjustable.

[0071] In this embodiment, there are many ways to adjust the fixing component 3 on the vertical support rod 2.

[0072] For example, a fixing sleeve 14 can be installed on the fixing component 3, which is then fitted onto the vertical support rod 2. A fixing threaded hole is provided on the side wall of the fixing sleeve 14, and a fixing bolt 15 passes through the fixing threaded hole and abuts against the vertical support rod 2, thereby fixing the fixing component 3 to the vertical support rod 2. When height adjustment is required, the fixing bolt 15 is loosened, the position of the fixing sleeve 14 is adjusted, and after adjusting to the appropriate height, the fixing bolt 15 is tightened.

[0073] Alternatively, a sliding groove adjustment structure can be used. A longitudinal groove is created on the vertical support rod 2, and a slider is located at the connection end of the fixed component. The slider is embedded in the groove, and coarse height adjustment is achieved by sliding the slider within the groove. The length of the groove determines the adjustment range. The structural logic is to restrict the rotational freedom of the fixed component 3, allowing only vertical sliding to ensure directional stability during adjustment. A locking mechanism is used to achieve positioning after height adjustment, designed in conjunction with the adjustment structure. The sliding groove adjustment structure is locked by a locking bolt or a ratchet mechanism. The locking bolt passes through the slider and presses against the side wall of the groove, or the ratchet engages with the toothed groove to fix the position.

[0074] In this embodiment, all components that come into contact with materials, such as the probe housing, stirring shaft 9, static sealing isolation cover 7, and stirring blades, are made of 316L stainless steel, Hastelloy, or titanium alloy and are highly polished (Ra ≤ 0.4 μm) or coated to meet the requirements of corrosion resistance, easy cleaning, and sterility.

[0075] The beneficial effects of this invention are: By integrating the base 1, support structure, stirring power unit 4, control module 5, detection module, and stirring module into a single integrated structure, stable assembly and collaborative operation of each component are achieved. The support structure provides a reliable installation foundation for the stirring power unit 4 and control module 5, ensuring the stability of the stirring process. The detection module is directly integrated with the stirring module, and the signal connection between the control module 5 and the detection module breaks the limitation of traditional stirring devices that can only provide stirring power, realizing the linkage between stirring action and parameter detection. The connection design between the stirring shaft 9, the stirring power unit 4, and the stirring blades 11 ensures efficient power transmission, enabling uniform mixing of materials. The overall structure is compact and adaptable to laboratory desktop scenarios, improving the integration and practicality of laboratory stirring operations.

[0076] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
