[0028] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, therefore only as an example, and cannot limit the protection scope of the utility model. The specific structure of the utility model is shown in the drawings. Figures 1-4

[0029] Embodiment 1: the utility model is used to solve one of the above technical problems, and the technical scheme adopted is: a carbon microsphere conveying and separating self-selection device, which comprises a horizontally fixed spiral conveying mechanism, a feed bin 1 is installed at the right end top of the spiral conveying mechanism and communicates with the inside of the spiral conveying mechanism, a vibrating screen material mechanism is installed below the left end of the spiral conveying mechanism, an orthogonal electromagnetic field mechanism is installed at the bottom of the vibrating screen material mechanism, a fixed speed reducer is installed at the left end of the spiral conveying mechanism, and the right end of the spiral conveying mechanism is used for external pneumatic system cooperation connection.

[0030] The vibrating screen material mechanism comprises a conical hopper 2 fixedly installed at the bottom discharge end of the spiral conveying mechanism, a first screen 3 and a second screen 4 are sequentially and spacedly installed in the conical cavity of the conical hopper 2 from top to bottom, a first discharge pipe 5 is installed at the outlet of the left side wall of the conical hopper 2 above the first screen 3, and a second discharge pipe 6 is installed at the outlet of the right side wall of the conical hopper 2 above the second screen 4.

[0031] ​The carbon microsphere conveying and separating self-selection device in the utility model can realize the conveying and separating of carbon microspheres, and can realize the separation of the carbon microspheres according to the electrical property and the magnetic property of the particles.

[0032] Preferably in any of the above solutions, the spiral conveying mechanism comprises a horizontal cylinder 7, end covers 8 are installed at the left and right ends of the horizontal cylinder 7, a conveying shaft 9 is installed in the conveying cavity of the horizontal cylinder 7, the left end of the conveying shaft 9 is used for being connected with the output end of the speed reduction driving part, and spiral conveying blades 10 are fixedly installed on the outer side wall of the conveying shaft 9 in the conveying cavity.

[0033] When the spiral conveying mechanism works, the speed reduction driving part drives the conveying shaft 9 to rotate, the spiral conveying blades 10 rotate together with the conveying shaft 9, and under the pushing of the spiral blades 10, the carbon microsphere material moves rightwards along the axial direction in the conveying cavity of the horizontal cylinder 7.

[0034] Preferably in any of the above solutions, the speed reduction driving part comprises a driving motor 11 which is fixedly installed, a speed reduction motor 12 is fixedly installed at the bottom of the motor shaft of the driving motor 11, and the output shaft of the speed reduction motor 12 is fixedly connected with the end of the conveying shaft 9.

[0035] The driving motor 11 and the speed reduction motor 12 are matched, the rotating speed of the conveying shaft 9 can be adjusted according to actual requirements, the conveying efficiency can be ensured, and the material conveying is not unstable or the equipment is not seriously worn due to the too high rotating speed.

[0036] In any of the above schemes, preferably, the orthogonal electromagnetic field mechanism comprises a square sorting cylinder 13 connected at the bottom outlet of the conical hopper 2, the square sorting cylinder 13 comprises two oppositely arranged parallel electrode plates 14, magnetic pole plates 15 are respectively arranged at the front and rear ends of the two electrode plates 14, the two electrode plates 14 and the two magnetic pole plates 15 are fixedly combined into the square sorting cylinder 13, an insulating blocking seat 16 is fixedly arranged at the bottom of the square sorting cylinder 13, and electric terminals 17 are respectively fixedly arranged on the outer sidewalls of the two electrode plates 14, one of the electrode plates 14 is connected to the positive electrode, and the other electrode plate 14 is connected to the negative electrode, a sorting cavity 18 is arranged in the square sorting cylinder 13, sorting material outlets 19 are respectively arranged at the bottom of the insulating blocking seat 16 near the inner sidewalls of the electrode plates 14 and the inner sidewalls of the magnetic pole plates 15, and sorting discharge pipes 20 with bottom valves are respectively fixedly arranged at the bottom of the insulating blocking seat 16 opposite to the sorting material outlets 19.

[0037] The orthogonal electromagnetic field formed by the electrode plates 14 and the magnetic pole plates 15 can effectively further separate the small-diameter carbon microsphere particles, and the sorting material outlets 19 and the discharge pipes 20 facilitate the collection of particles with different characteristics and subsequent processing. When the small-diameter carbon microsphere particles enter the sorting cavity 18 of the square sorting cylinder 13, under the joint action of the electric field and the magnetic field, the particles will move along their respective trajectories in the sorting cavity 18 due to the different electrical properties and magnetic properties, and finally enter the sorting discharge pipes 20 from different sorting material outlets 19. This realizes the re-separation of the small-diameter carbon microsphere particles screened by the vibrating screen material mechanism according to their electrical properties and magnetic properties, and further improves the sorting accuracy of the carbon microspheres.

[0038] Embodiment 2: Compared with Embodiment 1, the difference lies in that it further comprises the following technical features:

[0039] In any of the above schemes, preferably, the two magnetic pole plates 15 are both permanent magnet pole plates, and a magnetic field is formed between the two permanent magnet pole plates.

[0040] The use of permanent magnet pole plates eliminates the need for additional excitation equipment, has a simple structure, can stably provide a magnetic field, reduces equipment cost and energy consumption, and the permanent magnet pole plates themselves have magnetism, forming a stable magnetic field around them to provide a magnetic field part for the orthogonal electromagnetic field, so that the carbon microsphere particles entering the square sorting cylinder 13 are subjected to the action of the magnetic field force. In operation, the electric field formed by the electrode plates 14 jointly provides a magnetic field condition for the separation of the carbon microsphere particles in the orthogonal electromagnetic field, ensuring the smooth progress of the separation process.

[0041] In any of the above schemes, preferably, an electric field is formed between the two electrode plates 14 in the energized state.

[0042] By connecting the two electrode plates 14 to the positive and negative power supply respectively, an electric field will be generated between the two electrode plates 14, and the carbon microsphere particles entering the electric field will be affected by the electric field force. By forming an electric field through electrification, the electric field strength can be controlled by adjusting the voltage and other methods, making it convenient to adjust the separation effect according to the actual situation and improve the adaptability of the equipment. Similarly, in cooperation with the magnetic field, the carbon microsphere particles in the orthogonal electromagnetic field are affected by the electric field force and the magnetic field force, and the separation is realized according to the electrical and magnetic differences of the particles.

[0043] In any of the above schemes, it is preferred that the electric field and the magnetic field are perpendicular to each other and form an orthogonal electromagnetic field.

[0044] The electric field force and the magnetic field force act on the carbon microsphere particles at the same time, and the directions are perpendicular to each other. The particles will move according to a specific trajectory in this composite field according to their electrical properties, magnetic properties, and particle mass, etc., thereby realizing separation. The orthogonal electromagnetic field can make the carbon microsphere particles produce a unique motion trajectory under the action of the electric field force and the magnetic field force perpendicular to each other, improve the accuracy and efficiency of separation, and have better separation effect than single electric field or magnetic field. When working, it can enhance the separation effect of small-diameter carbon microsphere particles, further improve the separation accuracy of the entire device, and meet the demand for fine separation of carbon microspheres.

[0045] In any of the above schemes, it is preferred that a vibrating motor 21 is fixedly installed on the outer side wall of the conical hopper 2.

[0046] After the vibrating motor 21 is electrified and operates, a vibration force is generated and transmitted to the conical hopper 2, so that the conical hopper 2 and the first screen 3 and the second screen 4 inside it vibrate together, promoting the better flow and screening of the carbon microspheres on the screen. The setting of the vibrating motor 21 can make the conical hopper 2 vibrate, prevent the carbon microspheres from blocking the screen during the screening process, improve the screening efficiency, and ensure the continuity of the screening work.

[0047] In any of the above schemes, it is preferred that the inner diameter of the screen hole of the first screen 3 is larger than the inner diameter of the screen hole of the second screen 4; the left end of the first screen 3 is inclined downward, and the right end of the second screen 4 is inclined downward.

[0048] The large-diameter carbon microspheres are intercepted by the first screen 3, and because the left end of the first screen 3 is inclined downward, the large-diameter carbon microspheres move in the direction of the first discharge pipe 5 under the action of gravity and are discharged; the medium-diameter carbon microspheres are intercepted by the second screen 4 after passing through the first screen 3, and because the right end of the second screen 4 is inclined downward, the medium-diameter carbon microspheres move in the direction of the second discharge pipe 6 and are discharged. The design of screens with different screen hole diameters can more accurately separate carbon microspheres according to particle size; the inclined setting of the screen facilitates the movement of the carbon microspheres in the direction of the discharge pipe under the action of gravity, improving the screening efficiency. Further optimize the screening function of the vibrating screen material mechanism, and improve the screening accuracy and efficiency of carbon microspheres of different particle sizes.

[0049] In any of the above solutions, preferably, the conveying shaft 9 is in a hollow tube structure, with its left end blocked and its right end open, and a plurality of pulse bulk holes 22 are arranged on the outer wall of the conveying shaft 9 between the spiral conveying blades 10, the right end of the conveying shaft 9 is movably and sealingly connected with the pipeline of the external starting system, and the conveying shaft 9 can keep rotating in a fixed axis state in the working state.

[0050] The external pneumatic system delivers gas into the hollow conveying shaft 9 through the pipeline connected with the right end of the conveying shaft 9, and the gas is sprayed out of the pulse bulk holes 22 to generate a pulse thrust on the carbon microsphere material between the spiral conveying blades 10, thereby assisting the material conveying, and at the same time, under the pushing of the spiral conveying blades 10, the material is more uniformly conveyed to the right. The hollow tube structure and the pulse bulk holes 22 design can make the external pneumatic system deliver the material through the conveying shaft 9 in a pulse manner, better control the gas pressure of the gas flow delivered in the internal conveying cavity of the pulse bulk holes 22, effectively ensure the rapid blowing of the carbon microsphere particles in the conveying state, avoid the carbon microsphere particles from being agglomerated and accumulated, and improve the uniformity of the carbon microsphere conveying by the spiral conveying blades 10.

[0051] The working process of the carbon microsphere conveying and separating self-selection device is as follows:

[0052] Feeding and conveying: The external feeding equipment delivers the carbon microsphere material to the feeding bin 1, and the material falls into the conveying cavity of the horizontal cylinder 7 of the spiral conveying mechanism by gravity. The driving motor 11 in the speed reduction driving part provides power, and after the speed is adjusted and the torque is increased by the speed reduction motor 12, the left end of the conveying shaft 9 is driven to rotate, and the spiral conveying blades 10 rotate to push the carbon microsphere material to move axially to the right in the horizontal cylinder 7. In addition, the conveying shaft 9 is in a hollow tube structure, the right end is open and movably and sealingly connected with the pipeline of the external pneumatic system, the pneumatic system sprays gas out of the pulse bulk holes 22 on the conveying shaft 9 to assist the material blowing and continue to cooperate with the spiral conveying blades 10 to convey the material, so that the material conveying is more uniform.

[0053] Vibrating screening: The material enters the conical hopper 2 of the vibrating screening mechanism from the spiral conveying mechanism. The vibrating motor 21 on the outer wall of the conical hopper 2 works to make the conical hopper 2 and the first screen 3 and the second screen 4 inside vibrate to prevent the material from blocking the screen. The large-diameter carbon microspheres are intercepted by the first screen 3, and under the action of gravity, the large-diameter carbon microspheres move to the direction of the first discharge pipe 5 and are discharged through it; the medium-diameter carbon microspheres are intercepted by the second screen 4 after passing through the first screen 3, and the medium-diameter carbon microspheres move to the direction of the second discharge pipe 6 and are discharged through it.

[0054] Orthogonal electromagnetic field separation: after the vibration sieve, the remaining small diameter carbon microspheres fall into the square sorting cylinder 13 of the orthogonal electromagnetic field mechanism. The square sorting cylinder 13 is composed of electrode plates 14 and magnetic pole plates 15 at the front and rear ends arranged in opposite parallel and spaced, the electrode plates 14 are electrified to form an electric field, the magnetic pole plates 15 (using permanent magnet magnetic pole plates) form a magnetic field, the electric field and the magnetic field are perpendicular to each other to form an orthogonal electromagnetic field. Under the action of the orthogonal electromagnetic field, the small diameter carbon microsphere particles are subjected to electric field force and magnetic field force in different directions and sizes due to the difference in their own electrical properties and magnetic properties, thereby moving in the sorting cavity 18 according to their respective motion trajectories, and finally entering the corresponding sorting discharge pipe 20 from the sorting material outlet 19 at the bottom of the insulating plugging seat 16 in different positions, realizing further separation.

[0055] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application; any alternative improvement or change made by those skilled in the art to the embodiments of the present application falls within the protection scope of the present application.
