[0002] Spherical polysiloxanes can be used as fillers in high-frequency and high-speed circuit boards requiring low dielectric constant and low dielectric loss, as well as in semiconductor packaging materials, light diffusing agents, cosmetics, and anti-sticking agents. Spherical polysiloxanes can be calcined to obtain spherical silica. This synthetic spherical silica is characterized by high purity, small specific surface area, narrow particle size distribution, and the absence of large particles, making it widely applicable as a high-grade filler in high-speed circuit boards, semiconductor packaging, film opening agents, cosmetics, and rubber and plastic products.

[0003] Typically, existing technologies, such as CN205262890U, disperse powder samples in liquid and directly use a magnetic rod to contact the dispersion to collect and weigh the magnetic material. This process is quite cumbersome, and the magnetic material is not easy to separate from the magnetic rod. In addition, since the content of magnetic material in the synthetic spherical silica is relatively small, the error caused by weighing in this method is large, making it difficult to assess the subtle differences in the magnetic material of silica micropowder between different batches.

[0004] This patent describes a device for collecting magnetic materials from spherical silica powder. The device collects the magnetic materials from the powder using a magnetic column, and then photographs the size, structure, and quantity of the magnetic materials under a microscope to rate the state of magnetic materials in the spherical silica.

[0009] A further preferred technical solution is that the end of the rotating column without external threads is connected to the rotor of the rotating device.

[0010] A further preferred technical solution is that the contact portion between the bottle cap container and the bottle cap is elastic, so as to be sleeved onto the bottle cap by elastic clamping force.

[0011] A further preferred technical solution is that the contact portion between the magnetic column container and the magnetic column assembly is elastic, so as to be circumferentially sleeved onto the magnetic column assembly by elastic clamping force.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] The following detailed descriptions are not intended to limit the scope of this utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.

[0025] A device for collecting magnetic silicon micropowder includes a bottle assembly, a clamping assembly, an elastic sleeve assembly, and a magnetic column assembly, wherein: The bottle assembly includes the bottle body 1 and the bottle cap 2; The fixing clamp assembly includes two clamps 3 and a rotary joint 4 disposed on the side of one of the clamps 3; The elastic sleeve assembly includes a magnetic column container 5 and a bottle cap container 6; The magnetic pillar assembly includes several magnetic pillars 7; Several magnetic pillars 7 are installed in magnetic pillar mounting slots 9 on the base 8. The magnetic pillar assembly is installed in the magnetic pillar container 5. The bottle cap container 6 is fitted onto the bottle cap 2. The bottle cap 2 is screwed onto the bottle mouth of the bottle body 1. The clamp 3 is clamped at the connection between the magnetic pillar container 5 and the bottle cap container 6, and the clamp 3 is clamped within at least part of the axial range of the bottle cap 2.

[0026] In this embodiment, during assembly and use, several magnetic pillars 7 are first prepared and fixed, and placed in the magnetic pillar container 5. Then, the bottle body 1 and bottle cap 2 are washed, a certain mass of powder sample with magnetic particles is weighed and placed into the bottle body 1, and a dispersing solvent is added to the bottle body 1. The bottle cap 2 is then screwed tightly onto the bottle mouth of the bottle body 1. The bottle cap container 6 is then fitted onto the bottle cap 2, and the edges of the magnetic pillar container 5 and the bottle cap container 6 are aligned so that the magnetic pillars 7 are in precise contact with the bottle cap 2. The edges of the magnetic pillar container 5 and the bottle cap container 6 are clamped together by two clamps 3. Finally, the rotating device is connected to the rotary joint 4 on the clamp 3, and the device is rotated and shaken for a certain period of time to ensure that the powder sample is evenly dispersed in the dispersing solvent and in contact with the magnetic pillars 7 as much as possible. Then, the device is left to stand for a period of time.

[0027] After contact is complete, disassemble the rotating device and rotating joint 4, bottle cap 2 and bottle body 1, two clamps 3, bottle cap container 6 and bottle cap 2 in sequence. Note that when disassembling bottle cap 2 and bottle body 1, the magnetic column 7 and bottle cap 2 should always maintain precise contact. Use the above-mentioned dispersing solvent to rinse the excess powder sample on bottle cap 2 so that the remaining magnetic particles are clearly visible. Then, gather the remaining magnetic particles on bottle cap 2 towards the center and collect them.

[0028] In this embodiment, when the device is shaken, the bottle body 1 is rotated 180° so that the bottle cap 2 is below the bottle body 1, and left to stand for a period of time; then the bottle body 1 is rotated 180° so that the bottle cap 2 is above the bottle body 1, and shaken several times to ensure that the powder in the dispersion solvent is evenly distributed; this process is repeated several times until the magnetic particles in the dispersion solvent are in full contact with the bottle cap 2. Compared to hand-shaking, this shaking method theoretically ensures that the magnetic particles in the dispersion solvent and the bottle cap 2 make full contact once in each shaking cycle, resulting in better separation of the magnetic particles.

[0029] The magnetic column assembly also includes a base 8, on which a magnetic column mounting slot 9 is provided. The magnetic column 7 is inserted into the magnetic column mounting slot 9 by plugging it in, which ensures that the relative position of the magnetic column 7 and the bottle cap 2 does not change during shaking.

[0030] The rotary joint 4 is a cylindrical groove with internal threads, used to screw onto a rotary column 10 with external threads at one end. During rotation, the rotary column 10 can further achieve a tight screw connection with the cylindrical groove with internal threads, for example, the rotation direction is the same as the tightening direction, so that the rotary column 10 will not disengage from the cylindrical groove with internal threads during rotation.

[0031] The end of the rotating column 10 without external threads is connected to a rotating device, such as the rotor of a rotary electric motor. A rotary electric motor is a motor with a rotating rotor commonly used in the prior art.

[0032] The contact portion between the bottle cap container 6 and the bottle cap 2 is elastic, allowing it to be fitted onto the bottle cap 2 through an elastic clamping force. The contact portion between the magnetic pillar container 5 and the magnetic pillar assembly is elastic, allowing it to be circumferentially fitted onto the magnetic pillar assembly through an elastic clamping force. The bottle cap container 6 and the magnetic pillar container 5 have the same outer diameter. The design of the bottle cap container 6 makes it easier for the two clamping bodies 3 to clamp the connection between the magnetic pillar container 5 and the bottle cap 2, i.e., it is achieved by clamping the connection between the bottle cap container 6 and the magnetic pillar container 5. The edge of the bottle cap container 6 is slightly higher than the bottle cap 2, and the height difference between them is filled by the magnetic pillar 7, satisfying both the requirement for a precise fit between the magnetic pillar 7 and the bottle cap 2, and the requirement for a tight connection between the bottle cap container 6 and the magnetic pillar container 5; alternatively, the edge of the bottle cap container 6 may be slightly lower than the bottle cap 2, and the height difference between them is filled by the magnetic pillar container 5, achieving the same effect.

[0033] The contact portions of the magnetic column container 5 and the bottle cap container 6 with the clamping body 3 have friction surfaces. The presence of friction surfaces makes it less likely for the connection between the two clamping bodies 3 and the bottle cap container 6 and the magnetic column container 5 to become misaligned.

[0034] The magnetic column container 5 and the bottle cap container 6 are provided with slots 11, and the clamp 3 is provided with a fixing screw hole 12 corresponding to the slot 11. The slot 11 and the fixing screw hole 12 have the same specifications. The slot 11 can be provided with an internal thread of the same specifications and tightening direction as the fixing screw hole 12, or it can be without an internal thread. Using existing technology, a bolt with an external thread of the same specifications and tightening direction as the fixing screw hole 12 can be rotated and fixed in the fixing screw hole 12 and simultaneously fixed in the slot 11.

[0035] The clamp body 3 is provided with a connecting plate 13, and the connecting plate 13 is provided with a fixing hole 14. The two clamp bodies 3 are fixed together by using bolts of the same specifications as those in the fixing hole 14, which are in the prior art. Preferably, a nut with an internal thread of the same specifications and screwing direction as the bolt is also used for fixing. The two clamp bodies 3 can be fixed together by first inserting the bolt into the fixing hole 14 and then tightening the nut onto the bolt.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.
