Description

Technical Field

[0001] The utility model belongs to the technical field of battery material processing, is used for ICP testing of magnetic substances of battery negative electrode materials, and particularly relates to a magnetic substance adsorption device. Background Art

[0002] The current method for determining magnetic substances in battery electrode materials is: first, the electrode materials are dispersed in an ethanol medium, and then the magnetic substances in the electrode materials are adsorbed by rolling magnetic rods, and the magnetic substances adsorbed on the magnetic rods are heated and digested with an acid solution, and finally the content of magnetic substances such as iron, cobalt, chromium, nickel, and zinc is determined using an inductively coupled plasma emission spectrometer or an inductively coupled plasma mass spectrometer.

[0003] However, since electrode materials are generally graphite or silicon-based materials, and graphite or silicon-based materials are porous materials with a large specific surface area, magnetic substances are easily adsorbed in the pores. Currently, magnetic rods are mainly used to adsorb magnetic substances. Since magnetic substances are mostly adsorbed in the pores of porous materials, when magnetic substances are simply adsorbed using magnetic rods, the adsorption effect is low, resulting in a large deviation between the measured value and the true value. Therefore, there is currently no suitable laboratory pre-treatment device for testing magnetic substances in battery materials, which leads to deviations in the testing process of magnetic substances in battery materials. Utility Model Content

[0004] The purpose of the utility model is to provide a magnetic material adsorption device to overcome the problem of low adsorption rate of existing magnetic adsorption devices. The utility model can effectively improve the adsorption ratio of magnetic materials and reduce the deviation between the measured value and the true value.

[0018] Compared with the prior art, the utility model has the following beneficial technical effects:

[0019] The utility model provides a magnetic material adsorption device, comprising a container for containing electrode materials to be detected, an ultrasonic device placed outside the container, and a magnetic adsorption piece arranged inside the container. The ultrasonic wave generated by the ultrasonic device is used to ultrasonically oscillate the electrode material to be monitored, thereby reducing the agglomeration of the electrode material. At the same time, the ultrasonic wave can oscillate the magnetic material adsorbed in the holes of the electrode material, so that the magnetic material can escape from the holes of the ultrasonic material and float to the outside, which is conducive to the magnetic adsorption piece arranged inside the container to fully adsorb the magnetic material, thereby ensuring the adsorption accuracy of the magnetic material in the material to be detected.

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] like Figure 1 This is a schematic structural diagram of a magnetic material adsorption device 100 provided in the present application. Figure 2 yes Figure 1 Schematic diagram of the structure of the adsorption component 3.

[0026] See also Figure 1 and Figure 2 The magnetic material adsorption device 100 comprises: a container 1, an ultrasonic device 2 and an adsorption member 3. The ultrasonic device 2 is arranged outside the container 1 and is used to generate ultrasonic waves. The adsorption member 3 is arranged inside the container 1 and has magnetism, and is used to adsorb magnetic materials.

[0027] In this embodiment, the container 1 is used to contain the electrode material D of the battery to be tested. By arranging the ultrasonic device 2 outside the container 1 and generating ultrasonic waves, the ultrasonic waves generated by the ultrasonic device 2 are used to ultrasonically oscillate the electrode material D inside the container 1. After the electrode material D is subjected to the ultrasonic oscillation of the ultrasonic waves, the electrode materials D will be separated due to the action of the ultrasonic oscillation, thereby eliminating the agglomeration phenomenon between the electrode materials D; at the same time, the ultrasonic waves can act on the magnetic substances in the holes of the electrode material D, so that the magnetic substances are separated from the holes of the electrode material D, which is beneficial for the adsorption of the separated magnetic substances by the adsorption component 3. Therefore, when the magnetic substance adsorption device 100 of the present application is used to measure the magnetic substances in the electrode material D of the battery, the adsorption ratio of the magnetic substances can be increased, the deviation between the measured value and the true value can be reduced, and the detection accuracy can be improved.

[0028] It should be noted that the above-mentioned container 1 specifically adopts a glass container 1, a metal container 1 or a ceramic container 1, and a container with the same function made of other materials may also be adopted, and the embodiments of the present application are not limited to this.

[0029] It should also be noted that the frequency of the ultrasonic waves emitted by the ultrasonic device 2 can be adjusted according to actual needs.

[0030] It should also be noted that the above-mentioned adsorption component 3 refers to an adsorption structure with magnetic properties, which can be a magnet, an electromagnet, or other objects with the same function, and the embodiment of the present application does not limit this.

[0031] In some embodiments, see Figure 1 and Figure 2 , the container 1 is a vertical barrel, and the opening of the vertical barrel is upward. Compared with other shapes, the vertical barrel has the largest capacity when the bottom area is the same, which can increase the capacity of the container 1. Therefore, when each measurement experiment is carried out, more electrode materials D can be accommodated, and it is convenient to centrally set the adsorbent to achieve a better adsorption effect. In addition, when the opening of the vertical barrel is set at its upper part, it is conducive to the filling of the electrode material D and improves the efficiency of the measurement experiment.

[0032] In some embodiments, see Figure 1 and Figure 2 The ultrasonic device 2 is an annular ultrasonic device 2, and the annular ultrasonic device 2 is sleeved on the outer side of the vertical barrel. The ultrasonic waves generated by the ultrasonic device 2 can be uniformly transmitted to the electrode material D inside from all directions on the side of the vertical barrel. The electrode material D can be affected by ultrasonic waves in different directions, which is conducive to the electrode material D being separated from the hole of the electrode material D, thereby facilitating the adsorption of the separated magnetic material by the adsorption component 3, thereby increasing the adsorption ratio of the magnetic material.

[0033] In some embodiments, see Figure 1 and Figure 2 The magnetic material adsorption device 100 further includes an ultrasonic device base 4, which is disposed at the bottom of the annular ultrasonic device 2, and the ultrasonic device base 4 uses a counterweight. By disposing the ultrasonic device base 4 at the bottom of the ultrasonic device 2, the vibration of the ultrasonic device 2 when generating ultrasonic waves can be effectively suppressed, ensuring that the ultrasonic device 2 remains relatively stable during the ultrasonic oscillation process, which is conducive to the smooth progress of the experiment.

[0034] In some embodiments, see Figure 1 and Figure 2 The vertical barrel body adopts a cylindrical barrel body, and the annular ultrasonic device 2 is a circular annular ultrasonic device.

[0035] In some embodiments, see Figure 1 and Figure 2 The magnetic material adsorption device 100 also includes a stirrer 5, which is arranged inside the container 1, and the adsorbent 3 is fixed to the stirring end of the stirrer 5. When the adsorbent 3 is used to adsorb the magnetic material, the stirrer 5 is used to drive the adsorbent 3 to rotate synchronously, so that the electrode material D can be mixed and flowed, which is beneficial for the adsorbent 3 to fully contact with the magnetic material, thereby increasing the adsorption ratio of the magnetic material and reducing the deviation between the measured value and the true value.

[0036] In some embodiments, see Figure 1 and Figure 2 The magnetic material adsorption device 100 also includes a stirring driving device 6, which is used to drive the stirrer 5 to rotate. The stirring driving device 6 provides power for the rotation of the stirrer 5 to achieve the function of automatic stirring, thereby improving the stirring efficiency and the efficiency of the detection test. In addition, the stirring speed of the stirring driving device 6 can be controlled and adjusted, further improving the efficiency of the measurement test.

[0037] In some embodiments, see Figure 1 and Figure 2 The stirring driving device 6 specifically adopts an electric motor, which is fixed by a bracket. The electric motor has a simple structure, stable power output, and low cost, which can effectively reduce the manufacturing cost of the magnetic material adsorption device 100.

[0038] In some embodiments, see Figure 1 and Figure 2 The adsorbent 3 includes a permanent magnet coated with a polytetrafluoroethylene layer. The permanent magnet has strong magnetism and its magnetism does not change with time. When the permanent magnet is used as the adsorbent 3, the adsorption effect will be better, the adsorption ratio of the magnetic material can be increased, and the deviation between the measured value and the true value can be further reduced.

[0039] In some embodiments, see Figure 1 and Figure 2 The permanent magnet is specifically an annular permanent magnet. Compared with magnets of other shapes, the annular permanent magnet has a larger surface area, so that the permanent magnet is in full contact with the magnetic material, further increasing the adsorption ratio of the magnetic material and reducing the deviation between the measured value and the true value.

[0040] It should be noted that the annular permanent magnet is specifically in the shape of a circular ring or a rectangular ring, which is not limited in the embodiments of the present application.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
