Detailed implementation manners

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0023] Aluminum oxide powder refers to powder or particles made of aluminum oxide. Aluminum oxide is an inorganic compound with the chemical formula Al2O3, which is a compound of aluminum and oxygen. It is usually white or light yellow, and has high hardness and chemical stability. When processing aluminum oxide powder, a conveying device is needed to put the aluminum oxide powder into the internal of the powder processing equipment.

[0024] When the existing device feeds a large amount of powder into the body from the feed hopper, the probability of powder clogging at the hopper pipeline is relatively high. The main reason is that the particle size of the powder is fine and there is a certain degree of particle aggregation, which is easy to form a clogging phenomenon in the pipeline. Please refer to Figures 1 - 4 , the embodiment provides an aluminum oxide powder conveying device, including the body 1, and the feed hopper 2 and the discharge pipe 3 respectively arranged at the top and bottom of the body 1.

[0025] Reference Figures 1 - 4As shown, when a large amount of powder material of the existing device is put into the interior of the machine body 1 from the feed hopper 2, the probability of blockage of the powder material at the hopper pipeline is relatively high. The main reason is that the particle size of the powder material is fine and there is a certain degree of particle aggregation, which easily forms a blockage phenomenon in the pipeline. In order to improve the smoothness of the powder material feeding, the following settings are made specifically. A blockage prevention mechanism 4 for promoting the fluidity of the powder material is provided at the bottom of the feed hopper 2. The blockage prevention mechanism 4 includes a first motor 41 fixed to the top of the machine body 1. The output end of the first motor 41 is fixedly connected with a circular plate 42. The bottom end of the feed hopper 2 is fixedly communicated with a hose 45 that is fixedly communicated with the interior of the machine body 1. Both the hose 45 and the circumferential surface of the circular plate 42 are fixedly connected with like-pole magnets 43. When the powder material is put into the interior of the machine body 1 from the feed hopper 2, the first motor 41 is started. The output end of the first motor 41 drives the circular plate 42 to rotate. When the like-pole magnet 43 on the outer wall of the circular plate 42 rotates to the position of the like-pole magnet 43 on the outer wall of the hose 45, a repulsive reaction occurs, which causes the hose 45 to be subjected to a repulsive force, thereby pushing the hose 45 to move to the left. A power assembly for providing vibration to the powder material flowing inside the hose 45 is provided on the circumferential surface of the side of the hose 45 away from the like-pole magnet 43. The power assembly includes a sleeve rod 48 fixed to the machine body 1. A spring 44 and a pressing plate 47 are sequentially sleeved on the outer wall of the sleeve rod 48 from left to right. Both ends of the spring 44 are fixedly connected with the pressing plate 47 and the sleeve rod 48 respectively. A limiting plate 481 for restricting the movement range of the pressing plate 47 is fixedly connected to the end face of the sleeve rod 48. A buffer pad 471 for buffering the impact force on the limiting plate 481 is fixedly connected to the end of the pressing plate 47 away from the spring 44. Two connecting rods 49 are symmetrically and fixedly connected to the side of the pressing plate 47 away from the spring 44. The ends of the two connecting rods 49 away from the pressing plate 47 are fixedly connected with a fixed rod plate 46 fixedly connected with the hose 45. When the hose 45 moves to the left, the pressing plate 47 will squeeze the spring 44 on the outer wall of the sleeve rod 48. When the like-pole magnet 43 on the outer wall of the circular plate 42 continuously rotates away from the like-pole magnet 43 on the outer wall of the hose 45, the repulsive force disappears, and the elasticity of the spring 44 will cause the hose 45 to return to its original state. By circulating the above process, the hose 45 will sway left and right and vibrate. When the hose 45 sways left and right, the powder material inside will be affected by the wave shear. This shear action can change the arrangement and layout of the powder material, making it difficult for the powder material to form lumps or blockages in the hose 45. This mechanical action helps to maintain the uniform distribution of the powder material in the pipeline and maintain the stability of fluid mechanics; and the vibration can be transmitted to the powder material inside the hose 45. The vibration can break the static friction and surface tension between the powder materials, making it easier for the powder particles to slide and move. Especially for alumina powder, the vibration can effectively improve its fluidity, prevent it from accumulating and aggregating in the hose 45, thereby reducing the possibility of blockage. The vibration and swaying can also reduce agglomeration through void filling and minor fragmentation between the powder materials. Inside the hose 45, the voids existing between the powder materials or the larger particles can be filled by the action of vibration, reducing the voids, thereby reducing the possibility of agglomeration, so that the powder material can be quickly transmitted into the machine body 1 inside the hose 45.

[0026] Reference Figures 1 - 4 As shown in the figure, a feeding mechanism 5 for conveying powder is provided at the end face of the machine body 1. The feeding mechanism 5 includes a second motor 51 fixed to the end face of the machine body 1. The output end of the second motor 51 is fixedly connected with a rotating shaft 52. The outer wall of the rotating shaft 52 is fixedly connected with a spiral conveyor blade 53. After the powder enters the machine body 1, the second motor 51 is started. The output end of the second motor 51 drives the rotating shaft 52 to rotate, and the rotating shaft 52 drives the spiral conveyor blade 53 to rotate, thereby realizing the conveying of the powder.

[0027] Reference Figures 1 - 4 As shown in the figure, an extension pipe mechanism 6 for adjusting the discharging length of the discharging pipe 3 according to the height of the processing equipment is provided at the bottom end of the machine body 1. The extension pipe mechanism 6 includes a threaded rod 62 rotatably arranged at the bottom of the machine body 1. The outer wall of the bottom end of the threaded rod 62 is fixedly connected with a driving ring 61. The outer wall of the threaded rod 62 is threadedly connected with a vertically moving frame plate 63. One end of the vertically moving frame plate 63 is fixedly connected with a sliding plate. A sliding groove for the sliding plate to slide up and down is formed on the surface of the machine body 1. The bottom end of the discharging pipe 3 is fixedly communicated with an extension pipe 64. The bottom end of the extension pipe 64 is fixedly communicated with the top of the end of the vertically moving frame plate 63 far away from the limiting plate. When the processing equipment is too short, the driving ring 61 is rotated to make the vertically moving frame plate 63 threadedly move downward on the outer wall of the threaded rod 62. The downward movement of the vertically moving frame plate 63 stretches the extension pipe 64 to a suitable length adapted to the processing equipment. Compared with replacing discharging pipes 3 of different lengths, resources and costs are significantly saved. At the same time, the complexity of storing and managing discharging pipes 3 of multiple lengths is reduced, the efficiency of material management is improved, and thus the flexibility and practicality are improved.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
