Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and more specifically, to a fireproof conveying device for magnesium powder grinding. Background Technology

[0002] Magnesium powder, as a chemically highly reactive metal powder, plays an important role in industrial production and applications. However, currently, most magnesium powder is transported using pneumatic conveying devices, which carries several significant risks.

[0003] First, magnesium powder is highly reactive and readily undergoes an oxidation reaction with oxygen in the air. Under certain conditions, this oxidation reaction can become extremely vigorous, releasing a large amount of heat. Once the heat accumulates to a certain level, it can very likely trigger combustion, and in severe cases, even lead to an explosion, posing a significant threat to the production environment and personnel safety.

[0004] Therefore, to reduce this risk of combustion, existing pneumatic conveying devices for magnesium powder typically change the gas source from ordinary air to an inert gas, such as nitrogen. By using an inert gas as the conveying gas source, the contact between magnesium powder and oxygen can be effectively reduced, thereby significantly lowering the likelihood of combustion.

[0005] However, even with these measures, this conveying method still faces the problem of easy pipe blockage. In the magnesium powder processing, the magnesium powder must first be fed into a grinding device for grinding. However, because the quality of the raw materials entering the grinding device is difficult to guarantee, it may contain large particles or uneven materials, easily clogging the feed inlet of the grinding device. Once the feed inlet is blocked, it not only affects the grinding progress but may also damage the equipment, increasing maintenance costs. Furthermore, cleaning after a blockage is quite tedious, requiring a significant amount of time and manpower. Summary of the Invention

[0006] This invention proposes a fireproof conveying device for magnesium powder grinding, which solves the problem in related technologies where the feed port of the grinding device in the conveying device is difficult to clean and unclog after blockage.

[0007] The technical solution of the present invention is as follows:

[0008] A fire-resistant conveying device for magnesium powder grinding, used for loading and unloading materials into the grinding equipment, including:

[0009] The feeding pipeline has a first inlet and a first outlet, and also has a first branch pipeline and a first bend. The first outlet is connected to the inlet of the grinding device.

[0010] The first expansion joint is located at the end of the first branch pipe away from the first bend.

[0012] A cleaning device, one end of which is hinged to the other end of the first connecting rod, has a first abutting part. After the first telescopic member extends, the cleaning device approaches the first bend. After the first abutting part abuts against the inner wall of the feeding pipe, the cleaning device enters the first bend.

[0022] The third link is slidably disposed inside the housing. One end of the third link is hinged to the other end of the second link. The third link has a first insertion part. After the first rotating ring rotates, the first locking part abuts against or releases from the first insertion part.

[0023] The second elastic element has two ends that abut against the end of the first connecting rod near the first mounting part and the end of the second connecting rod near the third connecting rod, respectively, to provide a force that moves the end of the first connecting rod away from the end of the second connecting rod.

[0024] Optionally, a plurality of the first mounting portions, the first connecting rod, the second connecting rod, and the third connecting rod are all evenly distributed around the circumference of the first rotating ring axis.

[0025] Optionally, it also includes:

[0026] A linkage ring, which passes through the other end of several third links, is slidably disposed on the outside of the extended end of the second telescopic member.

[0027] Optionally, it also includes:

[0028] A rotating baffle is provided at one end of the first feed inlet. After the rotating baffle is rotated, the first feed inlet is closed or opened.

[0029] A first elastic element, with its two ends hinged to the rotating baffle and the first feed port respectively, is used to provide a force for the rotating baffle to reset. After the rotating baffle is reset, the first feed port is closed.

[0039] Optionally, the feeding pipeline further includes:

[0040] A filtration device, one end of which is connected to the storage tank and the other end of which is connected to the nitrogen source.

[0041] The working principle and beneficial effects of this invention are as follows:

[0042] In this invention, to address the problem of difficulty in cleaning and unblocking the feed inlet of the grinding device in the conveying device of related technologies after blockage, a fireproof conveying device for magnesium powder grinding is designed. In the actual magnesium powder grinding production line, the feed pipeline is made of high-strength, corrosion-resistant materials to ensure no damage occurs during long-term magnesium powder conveying. The first feed inlet is positioned at a high level for easy connection to the upstream magnesium powder supply equipment. Magnesium powder enters the first feed inlet by gravity or auxiliary conveying equipment. The first branch pipeline can be branched according to actual needs. The design of the first bend section uses a reasonable bending radius, ensuring smooth material flow while reducing friction and damage to the magnesium powder. When blockage is found in the first bend section of the feed pipeline or periodic cleaning is required, the operator activates the first telescopic component through the control system. The first telescopic component can be an electric push rod, hydraulic rod, etc., with sufficient thrust and stability. One end of the first telescopic component is firmly installed at the end of the first branch pipeline away from the first bend section, ensuring no loosening or displacement during the pushing process. The first connecting rod is made of high-strength metal, with one end connected to the extended end of the first telescopic component via a hinge, allowing for flexible rotation during pushing. The cleaning device is normally in standby mode. When cleaning is required, the first telescopic component extends, pushing the first connecting rod and thus moving the cleaning device towards the first bend. After the first contact part of the cleaning device abuts against the inner wall of the feeding pipe, its shape allows the cleaning device to slide towards the first bend, ensuring effective removal of residual magnesium powder upon entering the bend. Once inside the first bend, the cleaning device removes the magnesium powder adhering to the inner wall of the bend through rotation and scraping, and this powder is then conveyed into the grinding device along with the subsequent material.

[0043] The advantages are that during the magnesium powder grinding process, magnesium powder tends to accumulate in the bends of the feeding pipeline, affecting material conveying efficiency and posing safety hazards. Manually cleaning the pipes after blockage wastes a significant amount of nitrogen, damaging resources. By installing a dedicated cleaning device, magnesium powder residue in the bends can be removed promptly and effectively, ensuring unobstructed flow and preventing nitrogen leakage, thus reducing production costs. Furthermore, the automated operation of the cleaning device reduces the labor intensity and safety risks of manual cleaning, improving production safety and reliability. In addition, the design of the first branch pipeline allows for flexible material distribution, adapting to different production needs and enhancing the flexibility and adaptability of the production line.

[0060] Reference Figures 1-10 As the first embodiment of the present invention, a fireproof conveying device for magnesium powder grinding is proposed, which is used for feeding and unloading the grinding device 1. It includes a feeding pipe 2, which has a first inlet 21 and a first outlet 22, and also has a first branch pipe 23 and a first bend 24. The first outlet 22 is connected to the inlet of the grinding device 1. One end of the first telescopic member 3 is disposed at the end of the first branch pipe 23 away from the first bend 24. One end of the first connecting rod 4 is hinged to the extended end of the first telescopic member 3. One end of the cleaning device 5 is hinged to the other end of the first connecting rod 4. The cleaning device 5 has a first abutment part 51. After the first telescopic member 3 extends, the cleaning device 5 approaches the first bend 24. After the first abutment part 51 abuts against the inner wall of the feeding pipe 2, the cleaning device 5 enters the first bend 24.

[0061] In this embodiment, to address the problem of difficulty in cleaning and unblocking the feed inlet of the grinding device in the conveying device in related technologies after blockage, a fireproof conveying device for magnesium powder grinding is designed. In the actual magnesium powder grinding production line, the feed pipe 2 is made of high-strength, corrosion-resistant material to ensure no damage occurs during long-term magnesium powder conveying. The first feed inlet 21 is positioned at a high level for easy connection to the upstream magnesium powder supply equipment. Magnesium powder enters the first feed inlet 21 by gravity or auxiliary conveying equipment. The first branch pipe 23 can be branched according to actual needs. The first bend 24 is designed with a reasonable bending radius, ensuring smooth material flow while reducing friction and damage to the magnesium powder. When blockage or periodic cleaning is detected in the first bend 24 of the feed pipe 2, the operator activates the first telescopic component 3 through the control system. The first telescopic component 3 can be an electric push rod, hydraulic rod, etc., with sufficient thrust and stability. One end of the first telescopic component 3 is securely installed at the end of the first branch pipe 23 away from the first bend 24, ensuring no loosening or displacement during the pushing process. The first connecting rod 4 is made of high-strength metal material, and one end is connected to the extended end of the first telescopic member 3 via a hinge, allowing it to rotate flexibly during pushing. The cleaning device 5 is normally in standby mode. When cleaning is required, the first telescopic member 3 extends, pushing the first connecting rod 4, which in turn moves the cleaning device 5 towards the first bend section 24. After the first abutting part 51 of the cleaning device 5 abuts against the inner wall of the feeding pipe 2, the shape of the first abutting part 51 allows the cleaning device to slide towards the first bend section 24, ensuring that residual magnesium powder can be effectively cleaned when entering the first bend section 24. After entering the first bend section 24, the cleaning device 5 cleans off the magnesium powder adhering to the inner wall of the bend through rotation, scraping, and other methods, and then enters the grinding device 1 along with the subsequent material conveying.

[0062] The advantages are that, during the magnesium powder grinding process, magnesium powder tends to accumulate at the bends in the feeding pipe 2, which not only affects material conveying efficiency but also wastes a significant amount of nitrogen gas inside the equipment during cleaning, causing resource damage. By installing a dedicated cleaning device 5, magnesium powder residue at the bends can be cleaned promptly and effectively, ensuring unobstructed flow in the conveying pipe and preventing nitrogen leakage, thus reducing production costs. Furthermore, the automated operation of the cleaning device 5 reduces the labor intensity and safety risks of manual cleaning, improving production safety and reliability. In addition, the design of the first branch pipe 23 allows for flexible material distribution, adapting to different production needs and improving the flexibility and adaptability of the production line.

[0063] Furthermore, the cleaning device 5 includes a housing 52, the shape of which is adapted to the shape of the first bent pipe portion 24. One end of the housing 52 is hinged to the end of the first connecting rod 4 away from the first telescopic member 3, and the first abutment portion 51 is located at the other end of the housing 52. One end of the second telescopic member 53 is disposed inside the housing 52. After the second telescopic member 53 extends out, the extended end of the second telescopic member 53 approaches the first abutment portion 51. The extended end of the second telescopic member 53 is flexible and adapted to the shape of the housing 52. The cleaning member 54 is disposed at the extended end of the second telescopic member 53. After the second telescopic member 53 extends out, the cleaning member 54 extends out of the housing 52 and abuts against the inner wall of the feeding pipe 2.

[0064] In this embodiment, the shape of the outer shell 52 of the cleaning device 5 is perfectly adapted to the first bend 24. The second telescopic member 53 can be an electric push rod, hydraulic rod, or pneumatic rod, etc., with an adjustable extension length and sufficient thrust. One end of the second telescopic member 53 is fixed inside the outer shell 52, and its extension and retraction can be precisely controlled by the control system. When cleaning is required, the second telescopic member 53 extends, pushing the extended end of the second telescopic member 53 towards the first abutment part 51. The extended end of the second telescopic member 53 is made of a flexible material, such as rubber or silicone, which can perfectly adapt to the shape of the outer shell 52 and avoid damage to the inner wall of the pipeline during the cleaning process. The cleaning member 54 is disposed at the extended end of the second telescopic member 53. The cleaning member 54 can be in the form of a scraper, brush, etc., selected according to actual needs. When the second telescopic member 53 extends, the cleaning member 54 extends out of the outer shell 52 and abuts tightly against the inner wall of the feeding pipeline 2, cleaning the inner wall by means of rotation, scraping, etc. During the cleaning process, the cleaning component 54 can adaptively adjust according to the shape and condition of the inner wall of the pipeline to ensure the maximum cleaning effect.

[0065] The advantages are that the outer shell 52 of the cleaning device 5 is adapted to the shape of the first bend 24, ensuring the comprehensiveness and effectiveness of the cleaning. The second telescopic component 53 allows the cleaning component 54 to extend and retract according to actual conditions, making operation more flexible and convenient. The flexible extension end avoids damage to the inner wall of the pipeline, extending its service life. The selectable form and adaptive adjustment function of the cleaning component 54 can adapt to different pipeline conditions and cleaning needs, improving the cleaning effect. This design can greatly improve the pipeline cleaning efficiency in the magnesium powder grinding process, reduce production interruptions and equipment failures caused by pipeline blockage or magnesium powder residue, lower production costs, and improve production efficiency.

[0066] Furthermore, the cleaning component 54 includes a first rotating ring 541, which is rotatably disposed inside the end of the housing 52 having a first abutment portion 51, and has a first snap-fit ​​portion 5411; a second rotating ring 542 is rotatably disposed at the protruding end of the second telescopic component 53, and has a plurality of first mounting portions 5421; a plurality of first connecting rods 543, one end of which is hinged to the first mounting portion 5421; and a second connecting rod 544, one end of which is hinged to the other end of the first connecting rod 543, at the hinge point between the first connecting rod 543 and the second connecting rod 544. It has a first cleaning part 5441; a third link 545 is slidably disposed in the housing 52, one end of the third link 545 is hinged to the other end of the second link 544, the third link 545 has a first insertion part 5451, after the first rotating ring 541 rotates, the first snap part 5411 abuts against or releases from the first insertion part 5451; the two ends of the second elastic member 55 abut against the end of the first link 543 near the first mounting part 5421 and the end of the second link 544 near the third link 545 respectively, for providing a force that moves the one end of the first link 543 away from the one end of the second link 544.

[0067] In this embodiment, when pipe inner wall cleaning is required, the control system is first activated to extend the second telescopic member 53. The second telescopic member 53 uses an electric push rod or hydraulic rod, etc., which has stable extension power. As the second telescopic member 53 extends, it drives the second rotating ring 542 connected to it, as well as the first connecting rod 543 and the second connecting rod 544 mounted on the second rotating ring 542, to extend outward from the outer shell 52. Next, the first rotating ring 541 is rotated. When the first rotating ring 541 is rotated, its first locking part 5411 gradually abuts against the first insertion part 5451 on the third connecting rod 545. In the abutting state, the third connecting rod 545 cannot slide inside the outer shell 52, thereby fixing the relative position between the third connecting rod 545 and the first rotating ring 541. Then, the second telescopic member 53 is retracted. During the retraction process, due to the abutting action of the first locking part 5411 and the first insertion part 5451, the first connecting rod 543 and the second connecting rod 544 are forced to fold. This folding mechanism ensures that the first cleaning part 5441 at the hinge of the first connecting rod 543 and the second connecting rod 544 firmly abuts against the inner wall of the pipe. This effectively removes impurities such as magnesium powder residue from the inner wall of the pipe. Subsequently, the first rotating ring 541 continues to rotate. During rotation, the connection between the first locking part 5411 and the first insertion part 5451 drives the entire cleaning structure to rotate, allowing the first cleaning part 5441 to thoroughly clean all parts of the inner wall of the pipe. When the cleaning work is complete and the cleaning part 54 needs to be retracted, the second telescopic member 53 extends first. At this time, the first connecting rod 543 and the second connecting rod 544 move away from each other under the action of the second elastic member 55, and are no longer in a folded state. The second elastic member 55 can be a spring or elastic rubber, etc., with good elastic restoring force. Next, the first rotating ring 541 is rotated in the opposite direction, causing the first locking part 5411 and the first insertion part 5451 to disengage. Finally, the second telescopic member 53 is retracted, and the cleaning part 54 is returned to the outer casing 52, awaiting the next cleaning task.

[0068] The advantage lies in the high flexibility and adaptability of the design structure of this cleaning component 54. Through the extension and retraction of the second telescopic component 53 and the rotation of the first rotating ring 541, the extension, folding, rotation, and retraction of the cleaning component 54 can be precisely controlled, adapting to the cleaning needs of pipe walls of different diameters and shapes. The foldable design of the first cleaning section 5441 allows the cleaning component 54 to be easily retracted into the outer casing 52 when not in use, reducing space occupation and facilitating storage and transportation. Simultaneously, during the cleaning process, the folded first cleaning section 5441 can tightly abut against the inner wall of the pipe, improving the cleaning effect and ensuring comprehensive and thorough cleaning. The cooperation between the first snap-fit ​​portion 5411 on the first rotating ring 541 and the first insertion portion 5451 on the third connecting rod 545, along with the provision of the second elastic component 55, makes the operation of the cleaning component 54 more stable and reliable. During the cleaning process, the position of the cleaning structure can be effectively fixed, preventing loosening or displacement and ensuring the smooth progress of the cleaning work.

[0069] Furthermore, several first mounting parts 5421, first connecting rods 543, second connecting rods 544 and third connecting rods 545 are evenly distributed circumferentially along the axis of the first rotating ring 541.

[0070] In this embodiment, in the structural design of the cleaning component 54, several first mounting portions 5421 are evenly distributed on the second rotating ring 542, providing stable support points for the installation of the first connecting rod 543, thereby ensuring the comprehensiveness and uniformity of the cleaning. Because the connecting rod is circumferentially distributed, the cleaning force can also be evenly distributed on the inner wall of the pipeline, avoiding localized over- or under-cleaning.

[0071] The advantages are that the circumferentially distributed structural design ensures comprehensive and uniform cleaning, avoiding the occurrence of cleaning dead zones. The synergistic effect between the various linkages makes the cleaning force more uniform, improving the cleaning effect and quality. This design can greatly reduce safety hazards and production problems caused by incomplete cleaning, extend the service life of pipelines, and improve the stability and reliability of magnesium powder grinding production. At the same time, the uniformly distributed cleaning force can also reduce damage to the inner wall of the pipeline, reducing equipment maintenance costs.

[0072] Furthermore, it also includes a linkage ring 546, which passes through the other end of several third links 545, and the linkage ring 546 is relatively slidably disposed on the outside of the extended end of the second telescopic member 53.

[0073] In this embodiment, a linkage ring 546 is provided in the structure of the cleaning component 54. The linkage ring 546 is made of high-strength metal material and has good rigidity and wear resistance. The linkage ring 546 passes through the other end of several third links 545, so that each third link 545 can move synchronously under the drive of the linkage ring 546. When the cleaning component 54 performs cleaning operations, the linkage ring 546 can remain stable and does not affect the adjustment of the cleaning structure. After the cleaning work is completed, when it is necessary to retract the cleaning component 54, the second telescopic member 53 extends first, so that the first link 543 and the second link 544 are separated from each other under the action of the second elastic member 55, without folding. At this time, the linkage ring 546 can help maintain the stability of the third link 545 and prevent accidental folding or movement.

[0074] The advantage is that when the cleaning component 54 is being recycled, the linkage ring 546 can help maintain the stability of the cleaning structure, prevent accidents, and make the recycling process smoother and more reliable.

[0075] Furthermore, it also includes a rotating baffle 6, one end of which is rotatably disposed at the first feed inlet 21. After the rotating baffle 6 rotates, the first feed inlet 21 is closed or opened. The two ends of the first elastic member 7 are respectively hinged to the rotating baffle 6 and the first feed inlet 21, and are used to provide the force for the rotating baffle 6 to reset. After the rotating baffle 6 resets, the first feed inlet 21 is closed.

[0076] In this embodiment, a special sealing structure is installed at the first feed inlet 21 in the magnesium powder grinding conveying fireproof device to prevent nitrogen waste. This sealing structure mainly consists of a rotating baffle 6 and a first elastic element 7. The rotating baffle 6 is made of a high-strength, corrosion-resistant, and well-sealing material, with one end hinged to the first feed inlet 21. When magnesium powder raw material needs to enter the feeding pipeline 2, the impact force of the material overcomes the elastic force of the first elastic element 7, causing the rotating baffle 6 to open and the material to smoothly enter the first feed inlet 21. The first elastic element 7 can be a spring, elastic rubber, etc., with both ends hinged to the rotating baffle 6 and the first feed inlet 21, respectively. Once the material has entered, the elastic force of the first elastic element 7 quickly resets the rotating baffle 6, closing the first feed inlet 21. During the magnesium powder grinding and conveying process, the entire equipment is filled with nitrogen. In this environment, if the first feed inlet 21 does not have an effective sealing measure, a large amount of nitrogen will escape, resulting in resource waste. The rotating baffle 6 design allows it to open the moment material enters and remain closed for the rest of the time, effectively shortening the opening time of the first feed inlet 21 and significantly reducing nitrogen waste. To further improve the sealing effect, a sealing gasket can be installed at the contact point between the rotating baffle 6 and the first feed inlet 21 to ensure that nitrogen does not leak when the system is closed. Furthermore, the opening and closing of the rotating baffle 6 can be precisely controlled by a control system, allowing for timely adjustment of the baffle's state according to the material conveying requirements.

[0077] The advantages are that by setting up the rotating baffle 6 and the first elastic element 7, the problem of nitrogen waste during magnesium powder grinding and conveying is effectively solved. The rotating baffle 6 can quickly open when material enters and quickly close after entering, greatly shortening the opening time of the first feed inlet 21, reducing nitrogen escape, saving resources, and lowering production costs. Good sealing performance ensures the stability of the nitrogen environment inside the equipment, improving the safety of magnesium powder grinding and conveying. The sealing gasket further enhances the sealing effect, preventing nitrogen leakage and providing a more reliable guarantee for the production process.

[0078] Furthermore, it also includes a feeding pipe 8, which is connected to the discharge port of the grinding device 1.

[0079] Furthermore, the feeding pipeline 8 includes a material storage tank 81, which is connected to the discharge port of the grinding device 1; a distribution box 82 is connected to the material storage tank 81; a distribution shaft 83 is rotatably disposed in the distribution box 82, and the distribution shaft 83 has a number of distribution blades 84; and a storage tank 85 is connected to the distribution box 82.

[0080] Furthermore, the feeding pipeline 8 also includes a Roots blower 86, which is connected to the distribution box 82. The connection between the Roots blower 86 and the distribution box 82 is located directly below the distribution box 82 and is connected to the storage tank 85. The air inlet of the Roots blower 86 is connected to a nitrogen gas source.

[0081] Furthermore, the feeding pipeline 8 also includes a filter device 87, one end of which is connected to the storage tank 85, and the other end is connected to a nitrogen gas source.

[0082] In this embodiment, the conveying fireproof device for magnesium powder grinding also includes a feeding pipeline 8. The feeding pipeline 8 is connected to the outlet of the grinding device 1. First, the feeding pipeline 8 includes a material storage tank 81, which is tightly connected to the outlet of the grinding device 1, ensuring that the ground magnesium powder can smoothly enter the storage tank for temporary storage and buffering through a well-sealed method. Next is a distribution box 82, which is connected to the material storage tank 81. A distribution shaft 83 is rotatably installed inside the distribution box 82, and the distribution shaft 83 has several distribution blades 84. During operation, the distribution shaft 83 is driven to rotate by a motor or other drive device, and the distribution blades 84 evenly distribute the magnesium powder from the material storage tank 81. Then there is a storage tank 85, which is connected to the distribution box 82 and is used to store the distributed magnesium powder. In addition, the feeding pipeline 8 is equipped with a Roots blower 86, which is connected to the distribution box 82, with the connection point located directly below the distribution box 82. This connection point is also connected to the storage tank 85. The air inlet of the Roots blower 86 is connected to a nitrogen source. After the Roots blower 86 is started, it generates a strong airflow, conveying the magnesium powder in the distribution box 82 to the storage tank 85. At the same time, nitrogen enters the Roots blower 86 from the air inlet, conveying it along with the magnesium powder to form a nitrogen protective atmosphere, preventing dangerous situations such as combustion of the magnesium powder during transportation. Finally, the feeding pipeline 8 also includes a filter device 87, one end of which is connected to the storage tank 85, and the other end is connected to the nitrogen source. During the process of nitrogen entering the storage tank 85 from the nitrogen source, the filter device 87 filters the nitrogen, removing impurities and ensuring the purity of the nitrogen. It also prevents magnesium powder from entering the nitrogen source system, protecting the normal operation of the nitrogen source equipment.

[0083] The advantage lies in integrating multiple parts of the feeding pipeline 8 into a highly efficient and safe magnesium powder feeding and conveying system. The combined design of the material storage tank 81, distribution box 82, distribution shaft 83, and storage tank 85 achieves uniform distribution and storage of the ground magnesium powder, improving the automation and efficiency of the production process. The distribution shaft 83 and distribution blades 84 ensure uniform distribution of magnesium powder, facilitating subsequent processing and use. The Roots blower 86 provides powerful force for the magnesium powder feeding and conveying, ensuring that the material can be quickly and stably transported to the storage tank 85. The introduction of nitrogen creates a nitrogen protective atmosphere, greatly improving the safety of the magnesium powder conveying process and effectively preventing accidents such as fires. The filter device 87 ensures the purity of the nitrogen, improving the safety of the magnesium powder conveying process. Simultaneously, the filter device 87 also prevents magnesium powder from entering the nitrogen gas supply system, protecting the normal operation of the equipment and extending its service life. The overall design reduces the labor intensity and cost of manual operation, improves production efficiency, and provides reliable protection for the magnesium powder grinding and conveying process.
