Description

Technical Field

[0001] This utility model belongs to the field of chemical technology, specifically relating to a carbon nanotube acid washing device. Background Technology

[0002] Carbon nanotube acid washing equipment is mainly used in the purification process of carbon nanotubes. Its main function is to remove impurities from carbon nanotubes, such as amorphous carbon, residual catalyst metal particles (e.g., iron, cobalt), and other non-carbon components. By using strong acids (such as nitric acid, sulfuric acid, or mixtures thereof), most of the metal catalyst particles and other non-carbon impurities can be effectively dissolved and removed. This process utilizes the good dissolving power of acids on metals and other non-carbon substances. After acid treatment, the carbon nanotubes need to be thoroughly cleaned to remove residual acid and other byproducts to ensure the purity of the final product.

[0003] Some existing carbon nanotube pickling equipment typically mixes the pickling solution and carbon nanotubes only through unidirectional rotary stirring. Unidirectional rotary stirring may not be able to fully mix the pickling solution and carbon nanotubes, resulting in some materials not being effectively cleaned. Furthermore, if the solid waste generated after pickling is not effectively separated and treated, it can easily cause blockage of the drainage pipe during the discharge process. Once the drainage pipe is blocked, the normal production process needs to be stopped for cleaning, which not only interrupts the production progress but also prolongs the entire processing cycle, thereby reducing the overall production efficiency.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This embodiment of the present invention provides a carbon nanotube pickling device that can achieve bidirectional reciprocating stirring of the stirring rod 207 without manual control, and automatically remove impurities from the surface of the filter screen 208b during wastewater discharge.

[0026] The pickling equipment body 100 includes an equipment shell 101, a pickling tank 102 fixedly installed on the top of the equipment shell 101, a top cover 103 fixedly connected to the inner wall of the equipment shell 101, a drain outlet 104 communicating with the inner cavity of the pickling tank 102, and a power distribution cabinet 105 fixedly installed on the outside of the equipment shell 101.

[0027] It should be noted that the equipment housing 101 is used to support and protect the pickling tank 102, the pickling tank 102 is used to contain the carbon nanotubes to be treated and the pickling solution, the top cover 103 is used to seal the pickling tank 102, and the drain outlet 104 is used to discharge the waste liquid in the pickling tank 102.

[0028] The processing mechanism 200 includes a servo motor 201 adapted to be installed on the top of the equipment housing 101, a connecting column 202 fixedly installed on the output end of the servo motor 201 via a coupling, a notched bevel gear 203 fixedly sleeved on the outer surface of the connecting column 202, a rotating rod 204 fixedly installed on the inner wall of the pickling tank 102 via a bearing, and a first bevel gear 205 and a second bevel gear 206 respectively fixedly sleeved on both sides of the rotating rod 204 and used in conjunction with the notched bevel gear 203.

[0029] It should be noted that the servo motor 201 is used to provide a power source to drive the stirring operation, and the connecting column 202 is used to transmit the rotational motion of the servo motor to the notched bevel gear 203. When the notched bevel gear 203 drives the first bevel gear 205 to rotate, the first bevel gear 205 can drive the rotating rod 204, the second bevel gear 206 and the stirring rod 207 to rotate synchronously. When the second bevel gear 206 rotates to the position of meshing with the notched bevel gear 203, the notched bevel gear 203 will drive the second bevel gear 206, the rotating rod 204, the first bevel gear 205 and the stirring rod 207 to rotate in opposite directions, so that the stirring rod 207 can fully mix the carbon nanotubes and pickling solution in the pickling tank 102.

[0030] Specifically, the first bevel gear 205 and the second bevel gear 206 are both located on the outside of the equipment housing 101. The first bevel gear 205 and the second bevel gear 206 are in opposite directions. A rotating bearing sleeve is installed at the connection between the rotating rod 204 and the equipment housing 101.

[0031] Furthermore, the processing mechanism 200 also includes several stirring rods 207 fixedly connected to the outer surface of the rotating rod 204, and a filter assembly 208 used to prevent waste from being directly discharged or from becoming clogged.

[0032] Preferably, the filter assembly 208 includes an extension tube 208a fixedly sleeved on the outer surface of the drain outlet 104, a filter screen 208b fixedly installed on the inner end face of the extension tube 208a, and a hollow disc 208c fixedly connected to the inner wall of the extension tube 208a.

[0033] It should also be noted that filter 208b is used to filter solid particles in waste liquid to prevent them from entering the drainage pipe and causing blockage.

[0034] It should be noted that the stirring rods 207 are arranged in a circumferential array on the outer surface of the rotating rod 204, and the extension tube 208a is connected to the inner cavity of the drain port 104.

[0035] Furthermore, the filter assembly 208 also includes an impeller 208d fixedly mounted on the top of the hollow disc 208c via a bearing, a connecting rod 208e fixedly connected to the inner surface of the impeller 208d, and a scraper 208f fixedly mounted on the outer end face of the connecting rod 208e and used in conjunction with the filter screen 208b.

[0036] When liquid flows from drain outlet 104 through extension pipe 208a, it can drive connecting rod 208e and scraper 208f to rotate synchronously, so that scraper 208f sweeps up impurities on the surface of filter screen 208b, thereby ensuring the filtration efficiency of filter screen 208b while greatly improving drainage smoothness.

[0037] Specifically, the connecting rod 208e and the scraper 208f are both located directly above the filter screen 208b, and the outer surface of the scraper 208f slides in contact with the inner surface of the filter screen 208b.

[0038] In use, the carbon nanotubes to be treated and the pickling solution are placed in the pickling tank 102. The pickling tank is sealed by the top cover 103 to prevent leakage. The servo motor 201 is turned on and the rotational motion is transmitted to the connecting column 202 through the coupling, which in turn drives the notched bevel gear 203 to rotate. The notched bevel gear 203 interacts with the first bevel gear 205 and the second bevel gear 206, which are respectively fixed on both sides of the rotating rod 204. When the notched bevel gear 203 drives the first bevel gear 205, the rotating rod 204, the second bevel gear 206 and the stirring rod 207 rotate synchronously. When the second bevel gear 206 meshes with the notched bevel gear 203, it will rotate in the opposite direction, so that the stirring rod 207 performs bidirectional reciprocating stirring to ensure that the pickling solution and the carbon nanotubes are fully mixed.

[0039] After the pickling process is completed: the waste liquid is discharged through drain outlet 104. During this process, the waste liquid first enters the extension pipe 208a and undergoes preliminary filtration through filter screen 208b to remove large particulate impurities and prevent them from entering the drain pipe and causing blockage. At the same time, as the liquid flows through the extension pipe 208a, the impeller 208d begins to rotate, driving the scraper 208f to rotate synchronously through the connecting rod 208e. This automatically sweeps up impurities on the surface of filter screen 205b while the liquid flows, ensuring that filter screen 208b flows smoothly and unobstructed during the liquid discharge process.

[0040] In summary, the processing mechanism 200 not only enables the stirring rod 207 to perform bidirectional reciprocating stirring without manual control, ensuring thorough mixing between the pickling solution and carbon nanotubes, but also automatically sweeps up impurities on the filter screen 205b during wastewater discharge, ensuring smooth and unobstructed discharge of the filter screen 208b. This achieves the effect of improving work efficiency and product quality while reducing maintenance needs and frequency.
