Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic powder transportation, and more specifically, to an anti-blocking device for a negative pressure conveying pipeline. Background Art
[0002] Magnetic powder is a kind of hard magnetic single-domain particle. It is made into magnetic slurry with adhesives, solvents, etc., and coated on the surface of plastic or metal substrate to make magnetic recording materials such as magnetic tapes, disks, and magnetic cards. Magnetic powder is the core component of magnetic coatings and the main factor that determines the magnetic properties of magnetic recording media.
[0003] Magnetic powder transportation usually adopts negative pressure conveying. The negative pressure conveying system uses a pneumatic conveying fan to suck the conveying system, forming a negative pressure airflow in the system. The logistics and air enter the conveying system through the suction port and reach the end with the airflow, and finally separate through filtration. Due to the existence of pressure difference, the outside air is sucked into the pipeline, and the material is brought into the pipeline with the movement of the air. After reaching the end, the material is separated from the air and collected, and the air is discharged into the atmosphere or recycled after purification.
[0004] For example, the authorization announcement number CN219469032U discloses a device for preventing sedimentation and blockage in a negative pressure conveying pipeline for powders. During the powder conveying process, the negative pressure conveying pipeline can be vibrated to shake up the powder settled at the bottom of the negative pressure conveying pipeline, and the negative pressure will draw it away to avoid sedimentation accumulation, thereby preventing the negative pressure conveying pipeline from being blocked.
[0005] However, the magnetic powder will accumulate into blocks during the accumulation process. It is difficult to extract it with negative pressure simply by vibration. This will cause the magnetic powder to settle and block the pipeline. A large vibration amplitude will have an impact on the pipeline, while a small vibration amplitude will have a poor anti-deposition effect. Utility Model Content

[0024] like Figures 1 to 3 As shown,
[0025] The invention discloses an anti-blocking device for a negative pressure conveying pipeline, comprising a pipeline 1 and a vibration motor 2 arranged outside the pipeline 1, wherein the vibration motor 2 is fixed to the outer wall of the pipeline 1 by a clamp 3, and an anti-deposition component is arranged in the pipeline 1, and the pipeline 1 is cleared by the anti-deposition component to avoid blockage of the pipeline 1.
[0026] The anti-deposition component includes a connecting rod 4, a rotating fan 5 and a micro motor 6 placed in the pipeline 1. The micro motor 6 is placed in the middle of the connecting rod 4. The rotating fan 5 is connected to the output end of the micro motor 6. The rotation of the micro motor 6 drives the rotating fan 5 to rotate in the pipeline 1 to break up the accumulated dust and make it easier to be sucked away by negative pressure.
[0027] A groove cavity 7 is provided inside the connecting rod 4, and a docking hole 8 connected to the groove cavity 7 is provided on the outer wall of the pipe 1. An electric wire electrically connected to the micro motor 6 is provided in the groove cavity 7. The electric wire is electrically connected to a USB interface. The USB interface is located in the docking hole 8. A sealing plug 9 is provided on the docking hole 8. The micro motor 6 is charged through the USB interface to ensure the endurance of the micro motor 6.
[0028] The connecting rod 4 is provided with a plurality of through holes 14 for powder to pass through. The opening positions of the through holes 14 are staggered with the positions of the groove chamber 7 , so that the dust sucked away by the negative pressure will not be blocked by the connecting rod 4 and can be sucked away through the through holes 14 .
[0029] The rotating fan 5 includes a connecting tube 12 and blades 13. The lower end surface of the rotating fan 5 is provided with a plurality of crushing bars 10. The outer wall of the crushing bar 10 is provided with a plurality of crushing teeth 11. The connecting tube 12 is sleeved on the output end of the micro motor 6. The connecting tube 12 is fixed to the output end of the micro motor 6 by screws. The blades 13 and the connecting tube 12 are integrally formed. The crushing teeth 11 are arranged on the lower end surface of the blades 13. The crushing bars 10 are made of rubber material, and the crushing teeth 11 are made of polyethylene material. The cross-section of the end of the crushing bar 10 is triangular. During the rotation process, the crushing bar 10 contacts with the accumulated dust and breaks it up. The crushing teeth 11 further separates the accumulated dust.
[0030] Working principle: when it is necessary to clean the dust accumulated in the pipe 1, first start the vibration motor 2 to vibrate the outer wall of the pipe 1 to shake off the dust on the inner wall of the pipe 1, and then start the micro motor 6. The micro motor 6 rotates, driving the rotating fan 5 to rotate together. The rotating fan 5 can break up the accumulated dust, and the vibration motor 2 shakes off the dust on the inner wall of the pipe 1. The dust broken up by the rotating fan 5 is sucked out by the negative pressure exhaust to avoid the blockage of the pipe 1. Since the crushing bar 10 is made of rubber, during the high-speed rotation process, the crushing bar 10 breaks up the accumulated dust, and the crushing teeth 11 further breaks up the relatively tightly accumulated dust, thereby realizing the step-by-step removal of the accumulated dust. The micro motor 6 is electrically connected to the USB interface to ensure the endurance of the micro motor 6.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
