DETAILED DESCRIPTION

[0025] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0026] As shown in Figure 1 and Figure 2 , a wet magnetic separation device 10 according to a preferred embodiment of the present application, the wet magnetic separation device 10 includes a base 101, a driving device 102, a rotating member 103, a support 104, a magnetic separation pot 105, a pot rack 106, a pull rod rack 107, a pull rod 108 and a magnetic member 109, the middle of the pull rod rack 107 is provided with a through hole 1071.

[0027] The driving device 102 is fixed on the base 101, the center of the rotating member 103 is fixedly connected with the output shaft 1021 of the driving device 102, the support 104 is fixed on the top surface of the rotating member 103, the pot rack 106 is arranged on the support 104, the magnetic separation pot 105 is a non-ferromagnetic material, the magnetic separation pot 105 is fixed on the pot rack 106, the pull rod frame 107 is connected on the support 104, the pull rod 108 passes through the through hole 1071, the magnetic member 109 is fixed on the top end of the pull rod 108, and the width of the magnetic member 109 is greater than the hole diameter of the through hole 1071, so that the magnetic member 109 is prevented from passing through the through hole 1071.

[0028] It can be understood that the driving device 102 can be one or a combination of motor driving devices, hydraulic driving devices or hydraulic driving devices. The magnetic member 109 can be one or a combination of permanent magnets (such as neodymium-iron-boron permanent magnets, ferrite permanent magnets), electromagnets (such as energized solenoids), soft magnetic materials (such as silicon steel sheets, permalloy). The rotating member 103 can be a turntable, a rotating drum, a rotating wheel or other structures that can meet the above assembly relationship.

[0029] Through the above scheme, the wet magnetic separation device 10 in the application pours the material to be magnetically separated into the magnetic separation pot 105, and adds an appropriate amount of water. At this time, the pull rod frame 107 is at the lowermost end, and the magnetic member 109 is separated from the magnetic separation pot 105 and does not play a magnetic separation function.

[0030] When magnetic separation is needed, the material to be magnetically separated and water are mixed first, the driving device 102 is started, the driving device 102 drives the rotating member 103 to rotate, the rotating member 103 drives the support 104 to make a circular motion in the horizontal plane, and since the magnetic separation pot 105 is fixed on the support through the pot rack 106, the support 104 drives the magnetic separation pot 105 to make a circular motion in the horizontal plane, so as to mix the material to be magnetically separated and water. The above scheme can replace the step of manually shaking the magnetic separation container through the driving of the driving device 102. Since the magnetic separation pot 105 is a non-ferromagnetic material, when the magnetic member 109 is pulled away from the magnetic separation pot 105 by the pull rod 108, the magnetic member 109 can avoid affecting the mixed solution, and the mixing function of the material to be magnetically separated and water can be realized.

[0031] Then, after the driving device 102 is turned off, the up-down position of the pull rod 108 in the pull rod frame 107 is adjusted according to the required magnetic force. The higher the position of the pull rod 108, the closer the magnetic member 109 is driven to the magnetic separation pot 105, and the greater the magnetic force received by the material to be magnetically separated. For example, the pull rod 108 can be pushed upwards, the pull rod 108 drives the magnetic member 109 to move upwards along the through hole 1071 and abut against the bottom of the magnetic separation pot 105, the material to be magnetically separated is screened through magnetism, and the solution is poured out from the magnetic separation pot 105 after standing.

[0032] Automatic mixing and manual magnetic separation can be carried out in sequence to realize a complete wet magnetic separation process, and after multiple uses, the experimental goal of wet magnetic separation can be achieved.

[0033] The through hole 1071 in the pull rod holder 107 has a certain friction force on the pull rod 108, which can prevent the pull rod 108 from sliding down, and at the same time, the pull rod holder 107 can have a certain holding effect on the up-down movement of the pull rod 108, so that the size of the magnetic force can be reflected by the relative position of the pull rod 108 and the magnetic separation pot 105. Therefore, compared with manual magnetic separation by only using hands, the quantitative adjustment of the magnetic force can be realized when using the pull rod holder 107 and the pull rod 108 in the present application for manual magnetic separation.

[0034] While the driving device 102 is driving, the pull rod holder 107 and the pull rod 108 are arranged to realize manual control of the magnetic force, which skillfully balances the screening difficulty and the screening cost. Due to the small size, it is suitable for laboratories or other individuals and organizations to use, which can reduce the screening difficulty while keeping a low screening cost.

[0035] In an embodiment, as shown in Figure 1 , the support 104 can include a fixedly connected bottom plate 1041 and two side plates 1042, the bottom plate 1041 is fixed on the top surface of the rotating piece 103, and the bottom plate 1041 is away from the center of the rotating piece 103 to be close to the outer side of the rotating piece 103, and the two side plates 1042 are vertically erected upward perpendicular to the top surface of the rotating piece 103; the pot holder 106 is fixedly connected with the side plates 1042, and the pull rod holder 107 is connected between the two side plates 1042 of the support 104.

[0036] On this basis, in an embodiment, referring to Figure 3 , the magnetic separation pot 105 can include a handle 1051, the handle 1051 is fixed on the side surface of the magnetic separation pot 105, and the pot holder 106 is rotatably connected with the two side plates 1042.

[0037] By arranging the handle 1051 and the rotating structure, the solution can be quickly poured without disassembling the magnetic separation pot 105. Since the magnetic separation pot 105 does not need to be moved, the influence of the solution shaking on the minerals at the bottom of the pot can be better reduced when pouring the solution.

[0038] On the basis of this scheme, the pot holder 106 can further include a locking structure, the locking structure is installed between the pot holder 106 and any side plate 1042, and the locking structure is used to limit the rotation of the pot holder 106 and the side plate 1042.

[0039] By installing the locking structure, the magnetic separation pot 105 and the side plate 1042 can be prevented from shaking when the driving device 102 is driving, and after unlocking, the pouring function can be normally used.

[0040] The locking structure can be a ratchet structure, a bolt fastening structure, a pin structure, etc., and is determined according to actual requirements.

[0041] It can be understood that if the locking structure is not installed, the magnetic separation pot 105 can also be kept stable by its own gravity.

[0042] In another embodiment, as shown in Figure 4 Both of the two side plates 1042 are provided with a sliding groove 10421 in the vertical direction, and the two ends of the pull rod frame 107 extend into the sliding grooves 10421, so that the pull rod frame 107 is in sliding connection with the two side plates 1042.

[0043] By opening the sliding grooves 10421 on the side plates 1042, the distance between the pull rod frame 107 and the magnetic separation pot 105 can be adjusted, so that the wet magnetic separation device 10 can be installed with magnetic separation pots 105 of different depths, so as to realize the purpose of screening solutions of different concentrations and different capacities.

[0044] At the same time, since the height of the pull rod frame 107 is adjustable, in combination with the pull rod 108, a more extensive distance adjustment function can be realized to meet the requirements of different magnetic strengths. Here, the distance refers to the distance between the magnetic separation pot 105 and the magnetic member 109.

[0045] Since the adjustable range of the distance is large, when the magnetic member 109 is damaged, different sizes and strengths of the magnetic member 109 can be replaced, and by appropriately adjusting the height of the pull rod frame 107, the original function can still be realized.

[0046] In another embodiment, as shown in Figure 4 The wet magnetic separation device 10 can also include a first spring 1010 and a second spring 1011, and the first spring 1010 and the second spring 1011 are each threaded on the pull rod 108. The bottom end of the pull rod 108 is provided with a protrusion 1081, the first spring 1010 is compressed between the magnetic member 109 and the pull rod frame 107, and the second spring 1011 is compressed between the pull rod frame 107 and the protrusion 1081.

[0047] Through the above scheme, the pull rod 108 and the pull rod frame 107 are no longer relatively fixed only by friction. The elastic forces of the first spring 1010 and the second spring 1011 can be different. By selecting the first spring 1010 and the second spring 1011 with different elastic forces, the position of the pull rod 108 in the pull rod frame 107 can be kept stable.

[0048] At the same time, the first spring 1010 and the second spring 1011 provide a reverse elastic force based on the pull rod frame 107, which can adjust the force when pulling the pull rod 108 and appropriately improve the hand feeling of use.

[0049] Based on this, as Figure 4As shown, the bottom end of the pull rod 108 can also be provided with a handle 1082 in an embodiment. The handle 1082 is provided to improve the hand feeling and reduce the fatigue during manual magnetic separation. The gravity of the handle 1082 can be used to assist in adjusting the opposing force of the first spring 1010 and the second spring 1011.

[0050] In any embodiment of the present application, as Figure 1 As shown, the base 101 can include several floor supports 1012.

[0051] By integrating the base 101 with the workbench, the device can be directly fixed on the workbench, and the driving device 102 is hidden under the table top, which can appropriately reduce the space occupation, thereby improving the space utilization and meeting the use requirements of the laboratory.

[0052] The workbench can be made of metal material, wooden material, etc., which does not affect the implementation of the present application.

[0053] On the basis of any of the above solutions, in an embodiment, as Figure 5 As shown, the top surface of the rotating member 103 can be provided with a plurality of connection holes 1031 arranged from the center to the edge, and the bottom plate 1041 is fixedly connected with the connection holes 1031 through bolts.

[0054] By providing a plurality of connection holes 1031, the position of the fixed bottom plate 1041 is adjusted, and the centrifugal distance of the magnetic separation pot 105 is adjusted, so as to adjust the centrifugal force required for magnetic separation, and to adapt to more extensive wet magnetic separation requirements.

[0055] As Figure 6 As shown, in order to improve the structural strength of the rotating member 103, the plurality of connection holes 1031 can be distributed on different radii on the disc surface, so as to ensure that the distances of different connection holes 1031 from the center of the rotating member 103 are different. Since the connection holes 1031 are not concentrated, the influence of the connection holes 1031 on the structural strength of the rotating member 103 can be reduced.

[0056] It can be understood that in the present application, Figure 5 and Figure 6 are exemplary top views, and in order to make the positions of the connection holes 1031 more clear, Figure 5 and Figure 6 hide some parts such as the magnetic separation pot, and the hidden parts do not mean that the corresponding parts are not provided in the solution.

[0057] In an embodiment of the present application, as Figure 7As shown, the wet magnetic separation device 10 can further include a counterweight 1013 arranged on the top surface of the rotating member 103; the center of gravity of the counterweight 1013 is away from the center of the rotating member 103 by a first distance X1, the center of gravity of the support 104 and the components on the support 104 is away from the center of the rotating member 103 by a second distance X2, and the product of the mass of the counterweight 1013 and the first distance X1 is equal to the product of the total mass of the support 104 and the components on the support 104 and the second distance X2.

[0058] By the above scheme, the counterweight 1013 is arranged at a position opposite to the magnetic separation pot 105, which can reduce the influence caused by the bias of the magnetic separation pot 105, so that the rotating member 103 rotates more stably, and the service life of the driving device 102 is improved.

[0059] Specifically, according to the centrifugal force formula (as shown in the following formula one):

[0060] F=mω 2 r (formula one).

[0061] In formula one, F is the centrifugal force, m is the mass, ω is the angular velocity, and r is the centrifugal distance. In the case of fixed angular velocity (i.e. constant speed), the centrifugal force F is proportional to the product of the mass m and the centrifugal distance r, i.e. F∝mr.

[0062] Therefore, in the present application, the product of the centrifugal distance and the mass on both sides is equal, i.e. Figure 7 X1*m2=X2*m2, so that a pair of centrifugal forces with equal size and opposite direction are generated on one side of the magnetic separation pot 105 and one side of the counterweight 1013, the centrifugal forces on both sides are offset, so that the rotating member 103 moves more stably.

[0063] It can be understood that the center of gravity of the object referred to in the present application can specifically refer to the projection of the center of gravity of the object on the rotating member 103. The shape and material of the counterweight 1013 are not limited, and any shape and material of the counterweight 1013 can be used, as long as it meets the description of the present application scheme.

[0064] On the basis of the above scheme, in an embodiment, a strip-shaped groove can be arranged on the top surface of the rotating member 103, the counterweight 1013 is slidably connected with the strip-shaped groove on the top surface of the rotating member 103, a screw device is arranged between the counterweight 1013 and the rotating member 103, the centrifugal distance of the counterweight 1013, i.e. the first distance X1, is adjusted through the screw device, so that the counterweight 1013 can adapt to the centrifugal force on one side of the magnetic separation pot 105 containing solutions with different weights, and the effect of approaching dynamic balance is achieved, and the stability of the rotating member 103 in operation is further improved.

[0065] In summary, the wet magnetic separation device 10 in the application can meet the requirements of electric mixing and manual magnetic separation by the power of the driving device 102 and the up-down adjustment of the pull rod 108, and has the advantages of high efficiency and low cost, and the space occupation is more reasonable, and it is more suitable for laboratory sample extraction.

[0066] Further, the application also provides a series of embodiments of pouring structure, pull rod frame 107 adjusting structure, counterweight 1013 balancing structure and the like, which can further improve the magnetic separation efficiency, increase the universality of the device and the durability of use.

[0067] The above is only the preferred embodiment of the application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the application, a number of improvements and substitutions can be made, and these improvements and substitutions should be considered as the protection scope of the application.
