Description

Technical Field

[0001] The utility model belongs to the technical field of material processing, and particularly relates to a demagnetizing device for carbon nanotubes. Background Art

[0002] During the production, processing and transportation of carbon nanotubes, due to the action of an external magnetic field, magnetic impurities are often adsorbed on the surface or inside of the carbon nanotubes. These magnetic impurities will seriously affect the performance of the carbon nanotubes, such as reducing their conductivity, changing their magnetic properties, and even affecting their stability and reliability in specific applications.

[0003] Traditional demagnetizing devices for carbon nanotubes usually use magnetic materials for removal, such as magnetic rods, magnetic separators, etc., but these methods have obvious defects:

[0004] First, the demagnetizing efficiency is not high, and it is difficult to completely remove the tiny magnetic impurities in the carbon nanotubes;

[0005] Second, the processing equipment is bulky and the operation is complex, which is not suitable for the demagnetizing operation of carbon nanotubes in small batches or with high-precision requirements.

[0006] Therefore, in order to solve the above problems, it is necessary to design a demagnetizing device for carbon nanotubes. Content of the Utility Model

[0007] The purpose of the utility model is to provide a demagnetizing device for carbon nanotubes to solve the technical problem of low demagnetizing efficiency of the existing demagnetizing device.

[0008] To solve the above technical problem, the utility model provides a demagnetizing device for carbon nanotubes, including:

[0009] A box body, which includes: a feeding port located at the top of the box body and a discharging port located at the bottom of the box body;

[0010] At least two demagnetizing components with the same structure; where

[0011] Any one of the demagnetizing components is arranged obliquely below another demagnetizing component;

[0012] The demagnetizing component includes: a rotating shaft bearing-connected to the box body, two fixing plates sleeved on the rotating shaft, and at least three trapezoidal magnets arranged between the two fixing plates; where

[0013] The hypotenuses of the trapezoidal magnets are in contact with each other in sequence to cooperate with the two fixing plates to form a polyhedron; and

[0014] The polyhedron above is adapted to rotate towards the polyhedron below, so that the carbon nanotubes slide down onto the polyhedron below.

[0015] Further, the demagnetizing assembly further includes: a magnetic conductive plate disposed outside each trapezoidal magnet; wherein

[0016] each of the magnetic conductive plates is adsorbed on the corresponding trapezoidal magnet; and

[0017] each of the magnetic conductive plates is adapted to contact the two fixing plates to block the direct contact between the magnetic impurities in the carbon nanotubes and the trapezoidal magnets.

[0018] Further, a feed hopper communicating with the feed inlet is provided at the top of the box body; wherein

[0019] the feed hopper is directly above the upper polyhedron.

[0020] Further, a discharge pipeline communicating with the discharge outlet is provided at the bottom of the box body; wherein

[0021] the discharge pipeline is inclined.

[0022] Further, a transmission assembly is provided between the two demagnetizing assemblies; wherein

[0023] the transmission assembly includes: a transmission wheel sleeved on the corresponding rotating shaft, a transmission belt sleeved on the corresponding transmission wheel; and

[0024] any one of the transmission wheels is adapted to be driven by the transmission belt to drive the other transmission wheel to rotate.

[0025] Further, a bracket is provided outside the box body;

[0026] a motor is provided on the bracket; wherein

[0027] the motor is adapted to drive any one of the rotating shafts to rotate.

[0028] The beneficial effects of the present utility model are as follows:

[0029] (1). When the carbon nanotubes enter the box body from the feed inlet and pass through the first demagnetizing assembly, the magnetic impurities are adsorbed by the trapezoidal magnets. Under the rotation of the rotating shaft, the fixing plate and the trapezoidal magnet rotate, so that the carbon nanotubes on the trapezoidal magnet slide down to the trapezoidal magnet of the next demagnetizing assembly for continuous demagnetization treatment. The carbon nanotubes that have been demagnetized multiple times are discharged from the discharge outlet. Through the above steps, an efficient and in-depth demagnetization effect is achieved to fully and thoroughly remove the magnetic impurities in the carbon nanotubes.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions of the present utility model in conjunction with the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. Embodiment 1

[0044] As Figures 1 to 4 shown, this embodiment provides a demagnetizing device for carbon nanotubes, including:

[0045] The box body 1 includes: a feeding port located at the top of the box body 1 and a discharging port located at the bottom of the box body 1; at least two demagnetizing components 2 with the same structure; any one of the demagnetizing components 2 is arranged obliquely below another demagnetizing component 2; the demagnetizing component 2 includes: a rotating shaft 201 bearing-connected to the box body 1, two fixing plates 202 sleeved on the rotating shaft 201, and at least three trapezoidal magnets 203 arranged between the two fixing plates 202; the hypotenuses of the trapezoidal magnets 203 are in contact with each other in sequence to cooperate with the two fixing plates 202 to form a polyhedron; and the upper polyhedron is adapted to rotate towards the lower polyhedron to make the carbon nanotubes slide onto the lower polyhedron; it is most preferred to set six trapezoidal magnets 203.

[0046] In this embodiment, the carbon nanotubes enter the box body 1 from the feeding port. When passing through the first demagnetizing component 2, the magnetic impurities are adsorbed by the trapezoidal magnets 203. Under the rotation of the rotating shaft 201, the fixing plates 202 and the trapezoidal magnets 203 rotate, so that the carbon nanotubes on the trapezoidal magnets 203 slide onto the trapezoidal magnets 203 of the next demagnetizing component 2 for continuous demagnetization treatment. The carbon nanotubes that have been demagnetized multiple times are discharged from the discharging port. Through the above steps, an efficient and in-depth demagnetization effect can be achieved to fully and thoroughly remove the magnetic impurities in the carbon nanotubes.

[0047] The demagnetizing component 2 further includes: a magnetic conduction plate 204 arranged outside each trapezoidal magnet 203; each magnetic conduction plate 204 is adsorbed on the corresponding trapezoidal magnet 203; and each magnetic conduction plate 204 is adapted to contact the two fixing plates 202 to block the direct contact between the magnetic impurities in the carbon nanotubes and the trapezoidal magnets 203; by setting the magnetic conduction plates 204, the trapezoidal magnets 203 can be protected to prevent the magnetic impurities from directly wearing the trapezoidal magnets and extend their service life; secondly, when it is necessary to remove the magnetic impurities, the magnetic conduction plates 204 are directly removed. The magnetic conduction plates 204 lose magnetism and the magnetic impurities directly fall off, which is convenient for cleaning the magnetic impurities and reduces the cleaning time.

[0048] A feeding hopper 3 communicating with the feeding port is arranged at the top of the box body 1; the feeding hopper 3 is located directly above the upper polyhedron; by setting the feeding hopper 3, the effect of convenient feeding can be achieved; by arranging the feeding hopper 3 directly above the upper polyhedron, the effect of convenient direct demagnetization can be achieved.

[0049] A discharging pipeline 4 communicating with the discharging port is arranged at the bottom of the box body 1; the discharging pipeline 4 is inclined; by setting the discharging pipeline 4 and the discharging pipeline 4 is inclined, the effect of smooth discharging and reduced residue can be achieved.

[0050] A transmission component 5 is provided between the two demagnetization components 2; the transmission component 5 includes: a transmission wheel 501 sleeved on the corresponding rotating shaft 201, a transmission belt 502 sleeved on the corresponding transmission wheel 501; and any one of the transmission wheels 501 is adapted to be driven by the transmission belt 502 to drive the other transmission wheel 501 to rotate; when the transmission wheel 501 uses a belt transmission wheel, the transmission belt 502 uses a belt; when the transmission wheel 501 uses a gear, the transmission belt 502 uses a chain.

[0051] In this embodiment, since only two demagnetization components 2 are adopted, the transmission mode of the transmission wheel 501 and the transmission belt 502 is specifically adopted to rotate the lower demagnetization component 2 towards the side wall of the box body 1, reduce the passing gap of the carbon nanotubes, and enable the trapezoidal magnet 203 to strongly adsorb magnetic impurities. When multiple demagnetization components 2 are adopted, it is most preferable to use gear meshing between the rotating shafts 201, so that the upper demagnetization component 2 falls onto the lower demagnetization component 2, and at the same time the lower demagnetization component 2 falls onto the lower lower demagnetization component 2, so as to avoid the effect that only two demagnetization components 2 rotate in the same direction.

[0052] A bracket 6 is provided on the outer side of the box body 1; a motor 7 is provided on the bracket 6; and the motor 7 is adapted to drive any one of the rotating shafts 201 to rotate.
