Description

Technical Field

[0001] The utility model relates to the technical field of filtering, in particular to a filtering device. Background Art

[0002] Carbon nanotubes are a unique nanomaterial formed by the curling of carbon atoms into a tubular structure. They have excellent mechanical, electrical, thermal and chemical properties and are widely used in electronic devices, composite materials, sensors and energy. However, the filtration and treatment of carbon nanotube powders is a technical challenge. Due to their unique structure and surface properties, they are prone to agglomeration, which affects their application performance. Therefore, it is particularly important to effectively filter and disperse carbon nanotube powders. The filtration process aims to remove impurities in carbon nanotube powders and break up agglomerates, thereby improving the purity and uniformity of the powders and meeting the requirements of different application fields.

[0003] Some existing technologies often require pressurization during filtration, but the high-speed centrifugal pump used during pressurization will cause a large shear force on the carbon nanotube powder, resulting in breakage and damage of the carbon nanotubes. In addition, when processing carbon nanotube powder, existing filtration equipment often only focuses on filtration and ignores the agglomeration phenomenon of carbon nanotube powder, which often makes it difficult to achieve efficient filtration and dispersion processing. Utility Model Content

[0004] In view of this, the utility model provides a filtering device, which can reduce the impact of agglomeration on the quality of carbon nanotube powder, improve the filtering efficiency, and help maintain the integrity of the carbon nanotube structure.

[0005] In order to solve the above technical problems, the utility model provides a filtering device, including a diaphragm pump and a filtering assembly, the water inlet of the diaphragm pump is fixedly connected to a feed pipe, the water outlet of the diaphragm pump is fixedly connected to a discharge pipe, one end of the discharge pipe is connected to an extension pipe, and a filtering assembly is arranged in the middle of the discharge pipe, the filtering assembly includes a screen and an ultrasonic instrument, a screen is clamped on one side of the discharge pipe close to the extension pipe, and an ultrasonic instrument is fixedly connected to the inner wall of the discharge pipe. The ultrasonic instrument is used to reduce the influence of agglomeration on the quality of carbon nanotube powder, improve the filtering efficiency, reduce the shear force, and help maintain the integrity of the carbon nanotube structure.

[0006] A bracket is fixedly connected to the middle of the feed pipe, a rotating column is rotatably connected to the bottom of the bracket, and a plurality of blades are fixedly connected to the middle of the rotating column, so that the powder is broken up and stirred, thereby improving the uniform distribution of the powder.

[0007] A plurality of flow disturbance ports are provided in the middle of the blades, which further promotes the dispersion and mixing of the powder.

[0008] One end of the discharge pipe and one end of the extension pipe are fixedly connected with flanges, which prevent leakage and maintain system integrity.

[0009] The utility model also comprises bolts, and a plurality of bolts are arranged near the thread connection of the extension pipe flange, that is, the connection between the discharge pipe and the extension pipe is ensured.

[0010] The bottom of the diaphragm pump is fixedly connected with a plurality of supports, and a plurality of mounting openings are provided on both sides of the supports, that is, fixing points of the diaphragm pump are provided, thereby increasing the stability of the equipment.

[0011] The top of the feed pipe is fixedly connected with a connection plate, and the middle of the connection plate is provided with a plurality of mounting holes arranged in a circular array, so as to facilitate connection with an external feed device.

[0012] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When the carbon nanotube powder enters the feed pipe, the powder will drive the blades to rotate, and the blades will drive the spoiler to rotate synchronously, breaking up and stirring the carbon nanotube powder to make it more evenly distributed, which helps to improve the filtering effect.

At the same time, it can provide a certain pressure to enable the carbon nanotube powder to pass through the filter assembly faster, maintaining quality while improving filtration efficiency.

[0022] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] like Figure 1-4 As shown: This embodiment provides a filtering device, including a diaphragm pump 100 and a filtering assembly, the water inlet of the diaphragm pump 100 is fixedly connected to a feed pipe 101, the top of the feed pipe 101 is fixedly connected to a connection plate 110, the middle of the connection plate 110 is provided with a plurality of mounting holes arranged in a circular array, the water outlet of the diaphragm pump 100 is fixedly connected to a discharge pipe 102, one end of the discharge pipe 102 is connected to an extension pipe 103, the bottom of the diaphragm pump 100 is fixedly connected to a plurality of supports 109, and both sides of the supports 109 are provided with a plurality of mounting ports;

[0024] The diaphragm pump 100 is connected to an external feeding device through a connecting plate 110, and the contact area with the working surface is increased through a support 109. The diaphragm pump 100 can be further fixed through the mounting port, thereby improving the working stability of the diaphragm pump 100. The diaphragm pump 100 is started, and the diaphragm pump 100 causes the opening and closing of the suction chamber and the discharge chamber through the movement of the diaphragm, thereby forming a local vacuum to suck in the powder, and then the powder is sealed inside the pump, and finally the powder is discharged by the backward movement of the diaphragm to complete a cycle. The carbon nanotube powder is pressurized and transported to the discharge pipe 102 by the diaphragm pump 100, and then flows out through the extension pipe 103 after being filtered by the filter assembly. The diaphragm pump 100 exerts a small shear force on the material during the transportation process, which helps to reduce the breakage and damage of the carbon nanotubes and maintain their structural integrity. At the same time, it can provide a certain pressure to enable the carbon nanotube powder to pass through the filter assembly faster, thereby maintaining the quality and improving the filtration efficiency.

[0025] Filter components such as Figure 4 As shown,

[0026] A filter assembly is provided in the middle of the discharge pipe 102, and the filter assembly includes a screen 201 and an ultrasonic instrument 202. A mounting groove is provided on one side of the discharge pipe 102 close to the extension pipe 103, and the screen 201 is clamped in the middle of the mounting groove. A flange 107 is fixedly connected to one end of the discharge pipe 102 and one end of the extension pipe 103. The flange 107 close to the extension pipe 103 is threadedly connected to a plurality of bolts 108. The ends of the bolts 108 are threadedly connected to the flange 107 close to the discharge pipe 102, and an ultrasonic instrument 202 is fixedly connected to the inner wall of the discharge pipe 102.

[0027] The screen 201 is stuck in the installation groove, and then the extension tube 103 is aligned and fitted with the discharge tube 102, and the screen 201 is fixed between the extension tube 103 and the discharge tube 102. At this time, the two flanges 107 are fitted, and the two flanges 107 can be connected together by bolts 108 to make the connection between the discharge tube 102 and the extension tube 103 tighter. During filtering, the powder passes through the discharge tube 102 and the screen 201 and flows out of the extension tube 103. During this process, the ultrasonic instrument 202 is started, and the ultrasonic wave breaks the interaction force between the nanotubes, which helps to disperse the agglomerated carbon nanotubes, thereby obtaining a more uniform suspension.

[0028] Bracket 104 Figure 2 , 3 As shown,

[0029] A bracket 104 is fixedly connected to the middle of the feed pipe 101, and a rotating column is rotatably connected to the bottom of the bracket 104. A plurality of blades 105 arranged in an annular array are fixedly connected to the middle of the rotating column, and a plurality of spoiler ports 106 arranged in an array are opened in the middle of the blades 105;

[0030] When the carbon nanotube powder enters the feed pipe 101, the powder drives the blades 105 to rotate, and the blades 105 drive the spoiler 106 to rotate synchronously, breaking up and stirring the carbon nanotube powder to make it more evenly distributed, which helps to improve the filtering effect.

[0031] Working principle:

[0032] The diaphragm pump forms a partial vacuum between the suction chamber and the discharge chamber through the movement of the diaphragm, thereby sucking in the carbon nanotube powder through the feed pipe. When the carbon nanotube powder enters the feed pipe, the powder drives the blades to rotate to break up and stir the carbon nanotube powder. The diaphragm pump seals the sucked powder inside and pressurizes the powder to the outlet pipe through the backward movement of the diaphragm. The powder is physically filtered through the screen in the outlet pipe. During the filtration process, the ultrasonic instrument is started to break the interaction force between the nanotubes, which helps to disperse the agglomerated carbon nanotubes, thereby obtaining a more uniform suspension. The carbon nanotube powder that has been filtered through the screen and dispersed by ultrasonic waves finally flows out through the extension tube.

[0033] Through the above steps, the filtering device can effectively filter the carbon nanotube powder while maintaining the integrity of its structure and improving the filtering efficiency.
