Description

Technical Field

[0001] The utility model belongs to the technical field of stirring equipment, and more specifically, relates to a magnetic isolation component for micro-region multi-site stirring and a micro-region multi-site magnetic stirring device. Background Technique

[0002] Magnetic stirrers are very popular stirring equipment in the chemical field. Compared with other types of stirring equipment, only the stirring bar contacts the reaction liquid phase, and the entire stirring device can be located outside the reaction liquid container. The stirring device drives the rotation of the stirring bar through magnetic force to achieve stirring.

[0003] When conducting some control experiments, it is necessary to apply the same level of stirring to multiple containers to ensure the accuracy of the experiment. In many sub-fields, the miniaturization, quantification, and batch processing of experiments are a development direction. The containers used in experiments are getting smaller and more intensive, and finally developing towards the direction of micro-region multi-sites, that is, integrating multiple individual reaction units (i.e., reaction containers) in a set of equipment. Each reaction unit is relatively small and the distance between them is also relatively close.

[0004] Since the distance between each reaction unit is too close, if multiple magnetic stirring devices are simply directly set, the stirring bar will be affected by multiple stirring devices at the same time, resulting in inconsistent stirring effects. Therefore, it is often difficult to directly adopt the magnetic stirring method. Currently, a mechanical stirring device with a rotating shaft is usually used for stirring.

In the description of the present utility model, "a plurality of" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0032] Now, the magnetic isolation component for micro-region multi-site stirring and the micro-region multi-site magnetic stirring device provided by the present utility model will be described.

[0033] As Figure 1 shown, the first embodiment of the present utility model provides a magnetic isolation component for micro-region multi-site stirring, including a magnetic isolation component body 11. The magnetic isolation component body 11 is an integral component made of ferromagnetic material and is provided with a plurality of accommodation holes 12 for accommodating a magnetic stirring disk 20.

[0034] In use, the magnetic stirring disk 20 is installed in the receiving hole 12 of the magnetic isolation member body 11 and connected to the driving assembly. After that, the corresponding container is placed above the receiving hole 12, and then the reaction liquid and the stirring bar are put in. The driving assembly can drive the magnetic stirring disk 20 to rotate, and then the magnetic stirring disk 20 drives the stirring bar in the container to rotate through magnetic force.

[0035] Compared with the prior art, the magnetic isolation member for micro-region multi-site stirring provided in this embodiment can isolate different magnetic stirring disks 20 respectively through the integral magnetic isolation member body 11 made of ferromagnetic material, so that the magnetic force of the magnetic stirring disk 20 only generates an upward directional effect and does not affect the movement of adjacent magnetic stirring disks 20 and stirring bars. More precisely, even if there is an influence, the influence is within an acceptable range. Thus, it can realize uniform stirring of the micro-region multi-site, which is beneficial to reducing experimental errors.

[0036] As Figure 1 and Figure 4 shown, a specific implementation manner provided by the present utility model on the basis of the first implementation manner is as follows.

[0037] The magnetic isolation member body 11 is of a flat plate structure, which is convenient for the installation of the stirring equipment when cooperating with the stirring equipment.

[0038] An anti-corrosion coating or anti-corrosion layer is provided on the magnetic isolation member body 11 to improve the anti-corrosion performance of the magnetic isolation member body 11 and prevent it from being corroded by the splashed solution during use.

[0039] Mounting holes 13 are provided on the magnetic isolation member body 11 to facilitate the installation and fixation of the magnetic isolation member body 11 through fasteners such as screws.

[0040] Multiple receiving holes 12 are arranged in a rectangular array or a circular array on the magnetic isolation member body 11, which is convenient for the uniform arrangement of test tubes for stirring and is also convenient for processing and manufacturing.

[0041] In a specific embodiment, six receiving holes 12 are arranged in a 2*3 rectangular array on the magnetic isolation member body 11; in another specific embodiment, 24 receiving holes 12 are arranged in a 4*6 rectangular array on the magnetic isolation member body 11.

[0042] A heat dissipation structure is provided on the magnetic isolation member body 11 to improve the heat dissipation performance of the magnetic isolation member body 11 and prevent the generation of excessive temperature during use, which affects the stirring effect; specifically, the heat dissipation structure includes one or more of heat dissipation fins surrounding the outer periphery of the magnetic isolation member body 11, cooling channels arranged in the magnetic isolation member body 11, and heat conduction bridges arranged on the magnetic isolation member body 11 and other structures or components capable of dissipating heat from the magnetic isolation member body 11.

[0043] As Figures 2 to 5 shown, based on the same inventive concept, a second embodiment of the present utility model provides a micro-region multi-site magnetic stirring device, which includes the above-mentioned magnetic isolation member for micro-region multi-site stirring, a plurality of magnetic stirring disks 20, and a driving assembly 30. The plurality of magnetic stirring disks 20 are arranged in the accommodation holes 12 of the magnetic isolation member body 11 of the magnetic isolation member for micro-region multi-site stirring; the driving assembly 30 is connected to the plurality of magnetic stirring disks 20 to drive the magnetic stirring disks 20 to rotate.

[0044] During use, after placing the corresponding container above the accommodation hole 12 and then putting in the reaction liquid and the stirrer, the driving assembly can drive the magnetic stirring disk 20 to rotate, and then the magnetic stirring disk 20 can drive the stirrer in the container to rotate through magnetic force.

[0045] Compared with the prior art, the micro-region multi-site magnetic stirring device provided in this embodiment can, through the cooperation of the above-mentioned magnetic isolation member for micro-region multi-site stirring, a plurality of magnetic stirring disks 20, and the driving assembly 30, use the above-mentioned magnetic isolation member for micro-region multi-site stirring to separately isolate different magnetic stirring disks 20, so that the magnetic force of the magnetic stirring disks 20 only generates an upward directional effect and does not affect the movement of adjacent magnetic stirring disks 20 and stirrers, thereby enabling uniform stirring of the micro-region multi-sites, which is beneficial to reducing experimental errors.

[0046] As Figures 1 to 3 shown, a specific implementation manner provided by the present utility model on the basis of the second embodiment is as follows.

[0047] The micro-region multi-site magnetic stirring device further includes a mounting plate 40. The mounting plate 40 is respectively connected to the magnetic isolation member body 11 and the driving assembly 30 to facilitate the fixed positioning of the magnetic isolation member body 11 and the driving assembly 30. The part of the mounting plate 40 corresponding to the accommodation hole 12 is provided with a shaft hole for the power output shaft 31 of the driving assembly 30 to pass through.

[0048] The mounting plate 40 can facilitate the installation of the magnetic isolation member body 11 and the driving assembly 30, which is beneficial to simplifying the structure of the magnetic isolation member body 11, reducing the material limitation of the magnetic isolation member body 11, and the mounting plate 40 can also play a certain role in isolation and heat dissipation, and at the same time can facilitate connection with external structures such as the housing.

[0049] The mounting plate 40 is also provided with a groove corresponding to the accommodation hole 12 to facilitate increasing the depth of the accommodation hole 12; and the diameter of the shaft hole is smaller than the diameter of the accommodation hole 12 to facilitate the positioning of the power output shaft 31 of the driving assembly 30 and avoid friction and collision between the magnetic stirring disk 20 and the inner wall of the accommodation hole 12 when the magnetic stirring disk 20 rotates.

[0050] The driving assembly 30 can be a driver that drives multiple magnetic stirring disks 20 respectively through a transmission structure, or multiple individual drivers for driving the magnetic stirring disks 20; moreover, the driving assembly 30 can be connected to the main body 11 of the magnetic isolation member for fixed positioning, or it can be not connected to the main body 11 of the magnetic isolation member. In this case, it is fixed and positioned by being installed on other devices or connected through other components.

[0051] In some specific embodiments, there are multiple driving assemblies 30, which are arranged in one-to-one correspondence with the magnetic stirring disks 20; the driving assembly 30 is an element such as a motor that can output rotation. Specifically, it can be a motor that only contains a stator and a rotor, or it can be a motor with certain functions such as a reduction motor, a frequency conversion motor, or a stepping motor.

[0052] The top surface of the magnetic stirring disk 20 is lower than the outer end surface of the main body 11 of the magnetic isolation member, so as to prevent the magnetic stirring disk 20 from being exposed and causing magnetic interference.

[0053] As Figure 3 shown, in some embodiments, the magnetic stirring disk 20 includes a base 21 and two magnets 23. The middle part of the base 21 is connected to the power output end of the driving assembly 30, and limiting structures 22 are provided at both ends; the two magnets 23 are respectively installed on the limiting structures 22 at both ends of the base 21.

[0054] Such a structure can facilitate the installation and disassembly of the magnet 23 and the base 21, so as to replace magnets 23 of different sizes and lengths as needed to adjust the magnetic force acting on the stirring bar, so that the magnetic force is in a suitable state. The limiting structure 22 can be various plugging structures, clamping structures, bonding structures, or bolt connection structures, etc., which can install and position the magnet 23.

[0055] Specifically, as Figure 3 shown, the base 21 is a strip-shaped ferromagnetic structure, the limiting structure 22 includes a concave hole provided at the end of the base 21, and part of the magnet 23 is immersed in the concave hole, that is, the top of the magnet 23 is exposed. In this form, after the magnet 23 is installed in the concave hole of the base 21, it can be directly adsorbed on the base 21, which can avoid falling off or slipping, and the structure is simple and reliable.

[0056] As Figure 4 shown, in some other embodiments, the magnetic stirring disk 20 includes a base 21, two magnets 23 and a limiter 24. The middle part of the base 21 is connected to the power output end of the driving assembly 30; the two magnets 23 are respectively installed on the limiting structures 22 at both ends of the base 21; the limiter 24 is made of non-ferromagnetic material and is suspended on the base 21 and connected to the base 21. The limiter 24 is provided with a limiting through hole corresponding to the limiting structure 22 for the magnet 23 to pass through.

[0057] The limiter 24 can limit and fix the middle or top of the magnet 23, so as to effectively fix the magnet 23 when using a longer magnet 23, avoid the movement or slippage of the magnet 23, and at the same time avoid the too deep setting of the concave hole affecting the magnetic force effect. Even the concave hole may not be provided on the base 21.

[0058] In addition, this form is beneficial to forming the magnetic stirring disk 20 into a whole magnet to drive the stirrer to rotate more conveniently.

[0059] In a specific embodiment, the limiter 24 is an aluminum plate, the middle of the base 21 has a protrusion, and the aluminum plate is connected to the protrusion in the middle of the base 21 in forms such as a bolt connection structure, a welding structure, a clamping structure, etc.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
