[0002] Carbon nanotubes, also known as buckytubes, are one-dimensional quantum materials with a special structure. Their radial dimensions are in the nanometer range, their axial dimensions are in the micrometer range, and both ends of the tubes are basically sealed. Carbon nanotubes are mainly composed of several to dozens of layers of coaxial circular tubes of carbon atoms arranged in a hexagonal pattern. The distance between layers is fixed, about 0.34nm, and the diameter is generally 2 to 20nm. And according to the different orientations of the carbon hexagons along the axial direction, they can be divided into three types: zigzag, armchair, and spiral. Among them, spiral carbon nanotubes have chirality, while zigzag and armchair carbon nanotubes do not have chirality.

[0003] During the preparation of carbon nanotubes, the dispersion uniformity of the conductive slurry needs to be tested online. During use, the existing testing equipment only uses zirconia balls to stir the conductive slurry. During the test, the zirconia balls cannot mix the conductive slurry well, which can easily affect the accuracy of the conductive slurry test. Summary of the invention

[0004] The purpose of the present invention is to provide an online testing device for the dispersion uniformity of carbon nanotube conductive slurry to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an online testing device for the dispersion uniformity of a carbon nanotube conductive slurry, comprising a tank body, a first electrode and a second electrode, wherein the first electrode and the second electrode are both fixedly installed in the tank body, a tank cover is detachably installed on the top of the tank body, a motor is fixedly installed on the upper part of the tank cover through a motor seat, and an output end of the motor is connected to a stirring mechanism through a coupling;

[0006] The stirring mechanism comprises a stirring rod and a stirring blade, wherein the stirring rod is connected to the output end of the motor through a coupling, and the stirring blade is fixedly connected to the side of the stirring rod, and the angle between one end of the stirring blade and the horizontal plane is set to 20-25°, and the angle between the other end of the stirring blade and the horizontal plane is set to 7-10°;

[0007] A movable part is rotatably mounted on the side wall of the stirring blade, and the movable part can stir the conductive slurry in the tank.

[0008] In one embodiment of the present invention, the movable part includes a rotating rod rotatably mounted on the stirring blade and a driving plate, the driving plate is fixedly connected to the side wall of the rotating rod, and a first zirconia ball is mounted on the driving plate.

[0010] In one embodiment of the present invention, a swinging member is installed on the tank cover, and a toggle rod is fixedly connected to the side wall of the stirring rod, and the toggle rod is used to toggle the swinging member.

[0011] In one embodiment of the present invention, the swinging member includes a threaded rod, a second spring and a second zirconia ball, the thread of the threaded rod is installed on the top of the tank cover, one end of the second spring is fixedly connected to one end of the threaded rod, and the other end of the second spring is fixedly connected to the second zirconia ball.

[0012] In one embodiment of the present invention, the length of the toggle rod is 15-20 cm shorter than the length of the stirring blade.

[0013] In an embodiment of the present invention, a telescopic member is installed in the tank body, and the telescopic member is used to stir the conductive slurry.

[0014] In one embodiment of the present invention, the telescopic member includes a fixed ring, a protrusion, a movable rod and a third zirconia ball. The fixed ring is fixedly connected to the inner bottom of the tank body through a connecting rod. The protrusion is fixedly connected to the lower end of the stirring rod.

At the same time, the first zirconia ball contacts the slurry to stir the slurry, thereby improving the dispersion uniformity of the slurry and ensuring the accuracy of the test results.

[0019] When the stirring rod rotates, the toggle rod is driven to rotate. When the toggle rod rotates to the position of the second spring, the toggle rod bends the second spring. When the toggle rod is separated from the second spring, the second zirconia ball is driven to swing under the elastic recovery effect of the second spring to stir the slurry, thereby improving the uniformity of slurry dispersion and ensuring the accuracy of the test results.

[0020] When the stirring rod rotates, the protrusion is driven to rotate, thereby intermittently contacting the end of the movable rod. When the protrusion contacts the end of the movable rod, the movable rod is pushed to extend outward. When the protrusion is separated from the movable rod, the elastic recovery effect of the third spring pulls the movable rod to reset, thereby driving the third zirconia ball to perform telescopic stirring on the slurry at different positions, which can effectively improve the uniformity of slurry dispersion and ensure the accuracy of the test results during testing.

[0021] When the movable rod is extended and retracted, the slurry can be pushed to flow, so that the slurry is in a flowing state, which is beneficial to improving the stirring effect of the stirring blades. When the movable rod is extended and retracted, the movable rod is limited to prevent the movable rod from separating from the fixed ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The stirring mechanism includes a stirring rod 6 and a stirring blade 7, wherein the stirring rod 6 is connected to the output end of the motor 5 through a coupling, and the stirring blade 7 is fixedly connected to the side of the stirring rod 6, and the angle between one end of the stirring blade 7 and the horizontal plane is set to 20-25°, and the angle between the other end of the stirring blade 7 and the horizontal plane is set to 7-10°;

[0035] A movable part is rotatably mounted on the side wall of the stirring blade 7 , and the movable part can stir the conductive slurry in the tank body 1 .

[0036] It should be noted that the first electrode 2 and the second electrode 3 are used to energize the tank 1 to test the dispersion uniformity of the conductive slurry;

[0037] The first electrode 2 is located below the second electrode 3 .

[0038] By adopting the above scheme, through the use of a stirring mechanism, by setting the angle between one end of the stirring blade 7 and the horizontal plane to 20-25°, and the angle between the other end of the stirring blade 7 and the horizontal plane to 7-10°, when the stirring rod 6 drives the stirring blade 7 to rotate, the slurry can float up and the slurry at the bottom can be rotated up, thereby improving the dispersion uniformity of the slurry.

[0039] In this embodiment, the movable part includes a rotating rod 8 rotatably mounted on the stirring blade 7 and a driving plate 9, wherein the driving plate 9 is fixedly connected to the side wall of the rotating rod 8, and a first zirconia ball 10 is mounted on the driving plate 9;

[0040] A strip groove 11 is provided on the driving plate 9, a slide groove 12 is provided on the groove wall of the strip groove 11, a slider 13 is slidably installed in the slide groove 12, the slider 13 is fixedly connected to the side wall of the first zirconia ball 10, a first spring 14 is fixedly connected to the side wall of the first zirconia ball 10, and one end of the first spring 14 is fixedly connected to the groove wall of the strip groove 11.

[0041] By adopting the above scheme, through the use of the driving plate 9 and the rotating rod 8, when the stirring rod 6 drives the stirring blade 7 to rotate, the driving plate 9 and the rotating rod 8 move, and the driving plate 9 contacts the slurry. The resistance generated can make the driving plate 9 drive the rotating rod 8 to rotate about the axis of the rotating rod 8, thereby disturbing the slurry, and at the same time making the first zirconia ball 10 contact the slurry, stirring the slurry, and improving the dispersion uniformity of the slurry.

[0042] In this embodiment, a swinging member 15 is installed on the tank cover 4, and a toggle rod 16 is fixedly connected to the side wall of the stirring rod 6, and the toggle rod 16 is used to toggle the swinging member 15;

[0043] The swing member 15 includes a threaded rod 17, a second spring 18 and a second zirconia ball 19, the thread of the threaded rod 17 is installed on the top of the tank cover 4, one end of the second spring 18 is fixedly connected to one end of the threaded rod 17, and the other end of the second spring 18 is fixedly connected to the second zirconia ball 19;

[0045] It should be noted that the toggle rod 16 can contact the second spring 18 , so that the second spring 18 can be toggled.

[0046] By adopting the above scheme, through the coordinated use of the toggle rod 16 and the second spring 18, when the stirring rod 6 rotates, the toggle rod 16 is driven to rotate. When the toggle rod 16 rotates to the position of the second spring 18, the toggle rod 16 bends the second spring 18. When the toggle rod 16 is separated from the second spring 18, the second zirconia ball 19 is driven to swing under the elastic recovery action of the second spring 18 itself, thereby stirring the slurry, thereby improving the uniformity of the slurry dispersion.

[0047] In this embodiment, a telescopic part is installed in the tank body 1, and the telescopic part is used to stir the conductive slurry. The telescopic part includes a fixed ring 21, a protrusion 22, a movable rod 23 and a third zirconia ball 24. The fixed ring 21 is fixedly connected to the inner bottom of the tank body 1 through a connecting rod, and the protrusion 22 is fixedly connected to the lower end of the stirring rod 6. The side of the protrusion 22 can abut against one end of the movable rod 23. One end of the movable rod 23 passes through the fixed ring 21, and the movable rod 23 can slide.

[0048] It should be noted that the number of the movable rods 23 is no less than three.

[0049] By adopting the above scheme, through the use of the telescopic part, when the stirring rod 6 rotates, the protrusion 22 is driven to rotate, thereby intermittently interfering with the end of the movable rod 23. When the protrusion 22 contacts the end of the movable rod 23, the movable rod 23 is pushed to extend outward. When the protrusion 22 is separated from the movable rod 23, the elastic recovery effect of the third spring 25 pulls the movable rod 23 to reset, thereby driving the third zirconia ball 24 to perform telescopic stirring on the slurry at different positions, which can effectively improve the uniformity of slurry dispersion.

[0050] In this embodiment, a fixing plate 26 is fixedly sleeved on the rod wall of the movable rod 23 .

[0051] By adopting the above scheme, through the use of the fixed plate 26, when the movable rod 23 is telescopic, the slurry can be pushed to flow, so that the slurry is in a flowing state, which is beneficial to improving the stirring effect of the stirring blade 7, and when the movable rod 23 is telescopic, the movable rod 23 is limited to prevent the movable rod 23 from separating from the fixed ring.

[0052] Working principle: When in use, by setting the angle between one end of the stirring blade 7 and the horizontal plane to 20-25°, and the angle between the other end of the stirring blade 7 and the horizontal plane to 7-10°, when the stirring rod 6 drives the stirring blade 7 to rotate, the slurry can float up and the slurry at the bottom can be rotated up, thereby improving the dispersion uniformity of the slurry;

[0053] When the stirring rod 6 drives the stirring blade 7 to rotate, the driving plate 9 and the rotating rod 8 move, and the driving plate 9 contacts the slurry. The resistance generated can make the driving plate 9 drive the rotating rod 8 to rotate around the axis of the rotating rod 8, thereby disturbing the slurry, and at the same time make the first zirconia ball 10 contact the slurry to stir the slurry, thereby improving the dispersion uniformity of the slurry;

[0054] When the stirring rod 6 rotates, the toggle rod 16 is driven to rotate. When the toggle rod 16 rotates to the position of the second spring 18, the toggle rod 16 bends the second spring 18. When the toggle rod 16 is separated from the second spring 18, the second zirconia ball 19 is driven to swing under the elastic recovery effect of the second spring 18 to stir the slurry, thereby improving the uniformity of the slurry dispersion.

[0055] When the stirring rod 6 rotates, the protrusion 22 is driven to rotate, thereby intermittently contacting the end of the movable rod 23. When the protrusion 22 contacts the end of the movable rod 23, the movable rod 23 is pushed to extend outward. When the protrusion 22 is separated from the movable rod 23, the elastic recovery effect of the third spring 25 pulls the movable rod 23 to reset, thereby driving the third zirconia ball 24 to perform telescopic stirring on the slurry at different positions, which can effectively improve the uniformity of slurry dispersion.

[0056] When the movable rod 23 is extended and retracted, the slurry can be pushed to flow, so that the slurry is in a flowing state, which is beneficial to improving the stirring effect of the stirring blade 7. When the movable rod 23 is extended and retracted, the movable rod 23 is limited to prevent the movable rod 23 from separating from the fixed ring.
