Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of alumina powder transportation, and particularly relates to an alumina powder transportation pipeline. Background Art
[0002] Alumina powder is a white amorphous powder with the chemical formula Al2O3 and a molecular weight of about 102. It is an important chemical raw material with characteristics such as high hardness, high strength, heat resistance, and corrosion resistance. As an important inorganic material or raw material, alumina powder has been widely used in fields such as luminescent materials, catalysts, electronic substrates, rubber and plastic fillers, window materials, far-infrared materials, and bioceramics. Because alumina powder has strong hygroscopicity, if it is stored in a humid environment for a long time, the powder is likely to absorb moisture and gradually agglomerate. At the same time, if the particles of alumina powder are not properly dispersed, they may also adhere to each other due to electrostatic or gravitational forces, and then agglomerate, which will have a certain impact on the use effect.
[0003] In the existing technology, in the face of the agglomeration phenomenon, users usually choose to use specific equipment to disperse the alumina powder once before use or transportation to reduce the number of agglomerates, thereby ensuring the use effect of the alumina powder. However, this requires an additional process, resulting in losses of manpower and material resources. At the same time, alumina powder will also scatter to the outside during the process, which is very inconvenient. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a kind of alumina powder transportation pipeline is proposed.
[0005] To achieve the above purpose, the utility model provides an alumina powder transportation pipeline, which includes two pipe sections one. A pipe section two is fixedly installed between the two pipe sections one. A screening component is arranged inside the pipe section two, and a crushing component is arranged inside the pipe section two. The screening component is used to separate alumina powder agglomerates and alumina powder, and the crushing component is used to crush the alumina powder agglomerates and at the same time disperse the alumina powder.
[0006] In the above technical solution, further, the screening component includes two separation members distributed vertically. The separation member includes a fixed frame arranged inside the pipe section two. A uniformly distributed fixing block is fixedly connected between the fixed frame and the pipe section two. A through cavity is formed between the fixed frame and the pipe section two. A filter cover is fixedly connected to the top of the fixed frame.
[0007] In the above technical solution, further, an inclined section is fixedly connected to the outside of the fixed frame.
[0008] In the above technical solution, further, a through hole is provided at the top of the filter cover in the separating member located above, and the shape of the through hole is circular.
[0009] In the above technical solution, further, a concentrating hopper is fixedly connected inside the fixing frame in the separating member located below. The shape of the concentrating hopper is conical, a through hole is provided at the bottom of the concentrating hopper, and the shape of the through hole is circular.
[0010] In the above technical solution, further, the crushing assembly includes a motor fixedly connected to the outer wall of the second pipeline through a mounting plate, and a collecting ring fixedly connected inside the second pipeline. The output end of the motor is fixedly connected to a transmission shaft, and the transmission shaft is inserted and rotatably connected inside the second pipeline. An active bevel gear is fixedly connected to the outer wall of the transmission shaft. A baffle is fixedly connected to the inner side wall of the collecting ring. Uniformly distributed through holes are provided at the bottom of the collecting ring. A fixed shaft is fixedly connected to the inner side wall of the baffle through a fixing plate. The top of the fixed shaft is inserted and rotatably connected to a rotating block. A driven bevel gear II is fixedly connected to the top of the rotating block, and the driven bevel gear II meshes with the active bevel gear.

A rolling wheel is fixedly connected to the bottom of the L-shaped plate, and the rolling wheel rolls on the top of the collecting ring.

A protective cover is rotatably connected to the inner side wall of the fixed ring. A driven bevel gear I is fixedly connected to the bottom of the protective cover, and the driven bevel gear I meshes with the active bevel gear.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] Aluminum oxide powder enters the interior of the second pipeline from the first pipeline. First, it passes through the filter cover of the separating member located on the upper side. Its fine particles fall downward through the pores of the filter cover, while the lumps that cannot pass through and part of the aluminum oxide powder gradually move to the edge of the filter cover during continuous impact and finally fall downward through the through cavity. To adapt to different flow conditions, a through hole is provided at the top of the filter cover to prevent excessive aluminum oxide powder from being squeezed and falling downward through the through cavity when the flow rate is too large. Therefore, part of the aluminum oxide powder and lumps fall downward through the through hole together and are separated from the aluminum oxide powder falling from the upper separating member in the same way again. The advantage of this setting is that by separating twice in this way, the lumps existing in the aluminum oxide powder can be effectively separated. At the same time, during the separation process, it is inside the second pipeline and is connected to the pipeline transportation as a section, with good sealing performance and no dispersion situation;
[0014] The agglomerates fall along the cavity and finally drop onto the top surface of the collection ring. The user starts the motor through the controller to drive the transmission shaft to drive the driving bevel gear to rotate. Through the meshing relationship, the driven bevel gear two, the rotating block, and the L-shaped plate are synchronously driven to rotate, so that the rolling wheel rolls along the top surface of the collection ring. Under the enclosure of the baffle, the agglomerates falling here are continuously rolled. The crushed agglomerates then drop downward through the through holes. Through such a design, the agglomerates can be crushed, and the crushed agglomerates and the alumina powder drop together, making the present application more practical.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0021] As Figures 1 - 4 shown, an alumina powder conveying pipeline includes two first pipelines 1, and a second pipeline 2 is fixedly installed between the two first pipelines 1.
[0022] Through such a design, it is convenient for the user to install and replace.
[0023] The interior of the second pipeline 2 is provided with a screening component for separating alumina powder agglomerates and alumina powder. The screening component includes two vertically distributed separating members. Each separating member includes a fixed frame 6 disposed inside the second pipeline 2. A plurality of uniformly distributed fixing blocks 7 are fixedly connected between the fixed frame 6 and the second pipeline 2, forming a through cavity therebetween. The top of the fixed frame 6 is fixedly connected with a filter cover 5. A through hole 13 is formed at the top of the filter cover 5 in the separating member located above, and the shape of the through hole 13 is circular.
[0024] In the above arrangement, alumina powder enters the interior of the second pipeline 2 from the first pipeline 1. First, it passes through the filter cover 5 of the separating member located on the upper side. Its fine particles fall downward through the pores of the filter cover 5, while the agglomerates and some alumina powder that cannot pass gradually move to the edge of the filter cover 5 under continuous impact and finally fall downward through the through cavity. To adapt to different flow conditions, the through hole 13 is provided at the top of the filter cover 5 to prevent excessive alumina powder from being squeezed and falling downward through the through cavity when the flow rate is too large. Therefore, a part of the alumina powder and the agglomerates fall downward through the through hole 13 together, and are separated from the alumina powder falling from the upper separating member in the same way again. The advantage of this setting is that by performing two separations in this way, the agglomerates existing in the alumina powder can be effectively separated. At the same time, during the separation process, it is inside the second pipeline 2 and is connected to the pipeline transportation as a whole, with good sealing performance and no dispersion.
[0025] The interior of the second pipeline 2 is provided with a crushing component for crushing alumina powder agglomerates and at the same time dispersing the alumina powder. The crushing component includes a motor 3 fixedly connected to the outer wall of the second pipeline 2 through a mounting plate, and a collecting ring 8 fixedly connected inside the second pipeline 2. The output end of the motor 3 is fixedly connected with a transmission shaft 4, and the transmission shaft 4 is inserted and rotatably connected inside the second pipeline 2. A driving bevel gear 19 is fixedly connected to the outer wall of the transmission shaft 4. A retaining edge 9 is fixedly connected to the inner side wall of the collecting ring 8. A plurality of uniformly distributed through holes 16 are formed at the bottom of the collecting ring 8. A fixed shaft 10 is fixedly connected to the inner side wall of the retaining edge 9 through a fixing plate. The top of the fixed shaft 10 is inserted and rotatably connected with a rotating block 22. A driven bevel gear two 20 is fixedly connected to the top of the rotating block 22, and the driven bevel gear two 20 meshes with the driving bevel gear 19. Two L-shaped plates 12 are fixedly connected to the outer wall of the rotating block 22. A rolling wheel 11 is fixedly connected to the bottom of the L-shaped plate 12, and the rolling wheel 11 rolls on the top of the collecting ring 8. It also includes a dispersing member disposed on the top of the driving bevel gear 19.
[0026] In the above setting, the agglomerates fall along the cavity and finally reach the top surface of the collection ring 8. The user starts the motor 3 through the controller to drive the transmission shaft 4 to drive the driving bevel gear 19 to rotate. Through the meshing relationship, the driven bevel gear two 20, the rotating block 22 and the L-shaped plate 12 are synchronously driven to rotate, so that the rolling wheel 11 rolls along the top surface of the collection ring 8. Under the enclosure of the baffle 9, the agglomerates falling here are continuously rolled. The crushed agglomerates then fall downward through the through holes 16. Through such a design, the agglomerates can be crushed, and the crushed agglomerates and the alumina powder fall together, making the present application more practical.
[0027] The dispersing member includes a fixed ring 21 fixedly connected inside the concentrating hopper 15. The inner side wall of the fixed ring 21 is rotatably connected with a protective cover 17. The bottom of the protective cover 17 is fixedly connected with a driven bevel gear one 18, and the driven bevel gear one 18 meshes with the driving bevel gear 19.
[0028] Through such a design, through the meshing relationship, the driving bevel gear 19 synchronously drives the driven bevel gear one 18 and the protective cover 17 to rotate inside the fixed ring 21, dispersing the alumina powder located at the top, and at the same time not affecting the transmission of the driving bevel gear 19.
[0029] A concentrating hopper 15 is fixedly connected inside the fixed frame 6 of the separating member located below. The concentrating hopper 15 is conical in shape, and a through hole is opened at the bottom of the concentrating hopper 15. The shape of the through hole is circular.
[0030] Through such a design, the separated alumina powder is concentrated and moves closer to the center and then falls downward, avoiding overflowing to the top surface of the collection ring 8.
[0031] An inclined section 14 is fixedly connected to the outside of the fixed frame 6.
[0032] Through such a design, the alumina powder and the agglomerates move closer to the side of the pipe two 2 along the inclined section 14 during the sliding process, preventing them from tilting towards the center position, so that they cannot accurately fall onto the top surface of the collection ring 8.
[0033] Working principle:
[0034] Aluminum oxide powder enters from pipeline 1 into the interior of pipeline 2. First, it passes through the filter cover 5 of the separating member located on the upper side. Its fine particles fall downward through the pores of the filter cover 5, while the lumps that cannot pass through and some aluminum oxide powder gradually move to the edge of the filter cover 5 during continuous impact and finally fall downward through the through cavity. To adapt to different flow conditions, through holes 13 are provided at the top of the filter cover 5 to prevent excessive aluminum oxide powder from being squeezed and falling downward through the through cavity when the flow rate is too large. Therefore, a part of the aluminum oxide powder and lumps fall downward through the through holes 13 together and are separated from the lumps in the same way as the aluminum oxide powder falling from the upper separating member. The advantage of this setting is that by separating twice in this way, the lumps existing in the aluminum oxide powder can be effectively separated. At the same time, during the separation process, it is inside pipeline 2 and is connected to the pipeline transportation as one section, with good sealing performance and no escape situation;
[0035] The lumps finally fall onto the top surface of the collection ring 8. The user starts the motor 3 through the controller to drive the transmission shaft 4 to drive the driving bevel gear 19 to rotate. Through the meshing relationship, the driven bevel gear 20, the rotating block 22, and the L-shaped plate 12 are synchronously driven to rotate, so that the rolling wheel 11 rolls along the top surface of the collection ring 8. Under the enclosure of the baffle 9, the lumps falling here are continuously rolled. The crushed lumps then fall downward through the through holes 16. Through such a design, the lumps can be crushed, and the crushed lumps fall together with the aluminum oxide powder, making this application more practical;
[0036] Through the meshing relationship, the driving bevel gear 19 synchronously drives the driven bevel gear 18 and the protective cover 17 to rotate inside the fixed ring 21 to disperse the aluminum oxide powder located at the top, without affecting the transmission of the driving bevel gear 19 at the same time.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
