Feeding device of carbon nanotube conductive paste stirring kettle with premixing function

Abstract

This utility model relates to the field of carbon nanotube conductive slurry production technology, specifically a feeding device for a carbon nanotube conductive slurry stirring vessel with premixing function. The device includes a vessel body (which is the reactor body), a machine body (located on one side of the vessel body and serving as the feeding device body), a rotating column rotatably disposed inside the machine body, and multiple stirring shafts located outside the rotating column. These stirring shafts are used for premixing the slurry. This feeding device for the carbon nanotube conductive slurry stirring vessel with premixing function utilizes the cooperation between a protrusion and a pusher plate. When the protrusion pushes the pusher plate to a certain displacement, a movable plate pushes a scraper to move and contact the inner wall of the machine body. Then, as the rotating column rotates, the scraper scrapes away any residual slurry on the inner wall of the machine body, preventing slurry residue from failing to completely enter the reactor and ensuring the reusability of the device.

Description

Technical Field

[0001] This utility model relates to the field of carbon nanotube conductive slurry production technology, specifically to a feeding device for a carbon nanotube conductive slurry mixing vessel with premixing function. Background Technology

[0002] As is well known, carbon nanotubes are carbon allotropes with excellent electrical and mechanical properties, and are widely used in electronic devices, sensors, energy storage devices and other fields. Carbon nanotube conductive paste is a liquid made by mixing carbon nanotubes with chemical solvents. Due to its unique conductive properties, carbon nanotube conductive paste is used to prepare conductive films or conductive coatings. To improve the mixing effect before preparation, carbon nanotube conductive paste needs to be premixed before being put into the stirred tank. After premixing, it is put into the stirred tank for further mixing.

[0003] Existing feeding devices suffer from poor feeding efficiency because the carbon nanotube conductive slurry has high viscosity. The premixed slurry adheres to the inner wall of the premixing tank in the existing feeding device and cannot be completely fed into the reactor. Furthermore, the residual slurry affects the quality of other materials, requiring the entire feeding device to be disassembled for cleaning, which increases the workload of the operators. Summary of the Invention

[0004] Technical problems to be solved In order to overcome the problem of slurry residue in the feeding device of the existing carbon nanotube conductive slurry mixing vessel with premixing function, this utility model provides a feeding device for carbon nanotube conductive slurry mixing vessel with premixing function that has the effect of removing residual slurry.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a carbon nanotube conductive slurry mixing vessel with premixing function, comprising a vessel body, which is the main body of the reaction vessel; a machine body, which is disposed on one side of the vessel body and serves as the feeding device body; a rotating column, which is rotatably disposed inside the machine body; multiple sets of stirring shafts, which are disposed on the outer side of the rotating column and are used for premixing the slurry; multiple sets of adjusting components, each adjusting component comprising a balance block, which is disposed on the outer side of the rotating column; a horizontal plate slidably disposed on the outer side of the balance block; a push plate slidably disposed inside the horizontal plate; a protrusion, which is semi-elliptical, disposed on one side of the balance block; two sets of movable plates, which are slidably disposed on one side of the rotating column; a scraper, which is disposed on one side of the movable plates; and a driving component, which is disposed inside the rotating column and has one side fixedly disposed to the horizontal plate.

[0006] Preferably, a rotating motor is provided on one side of the machine body, and the output end of the rotating motor is keyed to one end of the rotating column.

[0007] Furthermore, a central shaft is provided on the side of the push plate near the balance block, and a pulley is rotatably provided on the outer side of the central shaft.

[0008] Furthermore, both sides of the horizontal plate are provided with fixing plates, one side of the fixing plate is provided with a limit rod, and both sides of the push plate are provided with sliders, which are slidably disposed on the outside of the limit rod.

[0009] In a further embodiment, a support plate is provided at one end of the limiting rod, and a first spring is provided on one side of the support plate. The end of the first spring away from the support plate is fixedly disposed with the slider.

[0010] Based on the aforementioned scheme, two sets of connecting rods are slidably arranged inside the movable plate, and the end of the connecting rod away from the movable plate is fixedly set on the outside of the rotating column.

[0011] Furthermore, based on the aforementioned scheme, a second spring is provided at the end of the connecting rod near the movable plate, and the end of the second spring away from the connecting rod is located inside the movable plate.

[0012] Furthermore, based on the aforementioned scheme, the drive assembly includes a rotary motor and a movable column. The rotary motor is disposed inside the movable column, and the movable column is rotatably disposed within the rotary column. A first threaded tube and a second threaded tube are respectively disposed at both ends of the movable column. The end of the first threaded tube away from the movable column is keyed to the output end of the rotary motor. Sleeves are screwed onto the outer sides of both the first and second threaded tubes. Two sets of mounting plates are disposed on the outer side of the sleeves. The side of the mounting plate away from the sleeve is fixedly disposed to a horizontal plate.

[0013] Beneficial effects The feeding device of this carbon nanotube conductive slurry mixing vessel with premixing function works by the cooperation between the protrusion and the pusher plate. When the protrusion pushes the pusher plate to move, the movable plate will push the scraper to move and contact the inner wall of the machine body. Then, when the rotating column rotates, the scraper will scrape off the slurry residue on the inner wall of the machine body, avoiding the situation where the slurry residue cannot completely enter the reaction vessel, thus ensuring the reusability of the device.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-7 The feeding device of the carbon nanotube conductive slurry mixing vessel with premixing function includes a vessel body 4, which is the main body of the reaction vessel. An organic body 1 is set on one side of the vessel body 4. The organic body 1 is the main body of the feeding device. A rotating motor 6 and a protective cover 5 are set on the top of the organic body 1. The protective cover 5 is located outside the rotating motor 6 and is used to protect the rotating motor 6. The output end of the rotating motor 6 extends into the organic body 1 and is keyed to the rotating column 7. Multiple sets of stirring shafts 10 and multiple sets of adjusting components 2 are set on the outside of the rotating column 7. After the rotating motor 6 is turned on, the output end of the rotating motor 6 will drive the rotating column 7 to rotate. At this time, the stirring shafts 10 will mix the slurry inside the organic body 1. A drive component 3 is set inside the rotating column 7, and one side of the drive component 3 is fixedly connected to one side of the adjusting component 2. Four sets of connecting rods 11 are welded to the outside of the rotating column 7. Movable plates 9 are slidably connected to the outside of two sets of connecting rods 11. A scraper 8 is fixedly connected to the side of the movable plate 9 away from the connecting rods 11.

[0018] Specifically, in order to enable the movable plate 9 to move back quickly, a second spring 12 is fixedly connected between the connecting rod 11 and the movable plate 9. Thus, when the movable plate 9 is pushed, the second spring 12 will be stretched by the movable plate 9, and when the movable plate 9 is no longer pushed, the second spring 12 will drive the scraper 8 to move back by bouncing the movable plate 9 back.

[0019] First, refer to Figures 2 to 4 In this embodiment, the adjustment component 2 includes a balance block 203, which is welded to the outside of the rotating column 7. A horizontal plate 201 is slidably connected to the outside of the balance block 203, and a push plate 207 is slidably connected to the inside of the horizontal plate 201. A protrusion 202 is welded to the side of the balance block 203 near the push plate 207, and the protrusion 202 is semi-elliptical.

[0020] Specifically, to prevent the push plate 207 from rubbing against the protrusion 202 and causing damage, a central shaft 213 is welded to the side of the push plate 207 near the protrusion 202. A pulley 205 is rotatably connected to the outside of the central shaft 213. Thus, the pulley 205 can replace the push plate 207 in contact with the protrusion 202, thereby preventing the push plate 207 from being damaged.

[0021] Meanwhile, in order to maintain the balance of the push plate 207, a fixing plate 206 is welded to both sides of the horizontal plate 201. A limit rod 212 is welded to one side of the fixing plate 206, and a slider 210 is welded to both sides of the push plate 207. The slider 210 is slidably connected to the outside of the limit rod 212. Thus, on the one hand, the limit rod 212 maintains the balance of the push plate 207 during movement, preventing the push plate 207 from becoming unbalanced and wobbling during movement, and ensuring the normal displacement of the push plate 207. On the other hand, the limit rod 212 restricts the direction of the push plate 207, preventing the device from failing due to misalignment of the push plate 207, and ensuring the normal use of the device.

[0022] Furthermore, in order to enable the push plate 207 to move back quickly, a support plate 208 is welded to the end of the limit rod 212 away from the fixed plate 206. A first spring 209 is fixedly connected between the support plate 208 and the slider 210. Thus, when the push plate 207 is pushed, the first spring 209 will be squeezed by the slider 210. When the push plate 207 is no longer pushed, the first spring 209 will drive the push plate 207 to move back by bouncing the slider 210.

[0023] Specifically, in order to prevent the slider 210 from hitting the horizontal plate 201 when it moves back, a buffer pad 211 is provided on the outside of the limit rod 212. The buffer pad 211 is a rubber buffer pad, and the buffer pad 211 is located on the side of the slider 210 away from the first spring 209. Thus, the buffer pad 211 can block the slider 210 and prevent the slider 210 from hitting the horizontal plate 201 when it moves back.

[0024] When the horizontal plate 201 moves, the pulley 205 will move accordingly and be pushed by the protrusion 202. At this time, the pulley 205 will drive the push plate 207 to move laterally by driving the central shaft 213. The movement of the push plate 207 will push the movable plate 9 to move laterally. The movement of the movable plate 9 will drive the scraper 8 to move and contact the inner wall of the machine body 1. After the rotating motor 6 is turned on, the scraper 8 will scrape off the residual slurry on the inner wall of the machine body 1.

[0025] Finally, see Figures 6 to 7 In this embodiment, the drive assembly 3 includes a rotary motor 301 and a movable column 304. The rotary motor 301 is a bidirectional motor, and its output end can rotate forward or backward. The rotary motor 301 is disposed inside the rotating column 7, and the movable column 304 is rotatably disposed inside the rotating column 7. A first threaded tube 303 and a second threaded tube 306 are respectively provided at both ends of the movable column 304. The threads on the outer sides of the first threaded tube 303 and the second threaded tube 306 are in opposite directions. The end of the first threaded tube 303 away from the rotating column 304 is keyed to the output end of the rotary motor 301. A sleeve 305 is screwed onto the outer side of both the first threaded tube 303 and the second threaded tube 306. When 306 rotates, the two sets of sleeves 305 will move towards each other or away from each other. Two sets of mounting plates 302 are provided on the outside of the sleeves 305. The side of the mounting plate 302 away from the sleeves 305 is fixedly set with the horizontal plate 201. After the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the first threaded tube 303 to rotate. The rotation of the first threaded tube 303 will drive the second threaded tube 306 to rotate by driving the movable column 304. The rotation of the first threaded tube 303 and the second threaded tube 306 will drive the two sets of sleeves 305 to move linearly. The movement of the sleeves 305 will drive the mounting plate 302 to move. The movement of the mounting plate 302 will drive the horizontal plate 201 to move.

[0026] The feeding device of the carbon nanotube conductive slurry stirring vessel with premixing function, through the cooperation between the protrusion 202 and the pusher plate 207, when the protrusion 202 pushes the pusher plate 207 to move, the movable plate 9 will push the scraper 8 to move and contact the inner wall of the body 1. Then, when the rotating column 7 rotates, the scraper 8 will scrape off the slurry residue on the inner wall of the body 1, avoiding the situation where the slurry residue cannot completely enter the reaction vessel, thus ensuring the reusability of the device.

[0027] Working principle: The feeding device of this carbon nanotube conductive slurry mixing vessel with premixing function is first placed in the desired position during use. Then, the slurry is premixed. Specifically, the operation is as follows: the rotary motor 6 is turned on, causing its output end to drive the rotating column 7 to rotate. The rotation of the rotating column 7 will drive the stirring shaft 10 to rotate, thus mixing the slurry inside the machine body 1. When it is necessary to clean the slurry residue on the inner wall of the machine body 1, the rotary motor 301 is turned on, causing its output end to drive the first threaded tube 303 to rotate. The rotation of the first threaded tube 303 will drive the second threaded tube 306 by driving the movable column 304. The rotation of the first threaded tube 303 and the second threaded tube 306 will cause the two sets of sleeves 305 to move linearly. The movement of the sleeves 305 will cause the mounting plate 302 to move. The movement of the mounting plate 302 will cause the horizontal plate 201 to move. When the horizontal plate 201 moves, the pulley 205 will move accordingly and be pushed by the protrusion 202. At this time, the pulley 205 will drive the push plate 207 to move laterally by driving the central shaft 213. The movement of the push plate 207 will push the movable plate 9 to move laterally. The movement of the movable plate 9 will drive the scraper 8 to move and contact the inner wall of the machine body 1. After the rotation motor 6 is turned on, the rotation of the rotating column 7 will drive the scraper 8 to rotate and scrape off the residual slurry on the inner wall of the machine body 1.
