Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a conveying fireproof device for magnesium powder grinding. Background Art

[0002] As a metal powder with extremely active chemical properties, magnesium powder plays an important role in industrial production and application. However, at present, most magnesium powder transportation uses pneumatic conveying devices, but there are many risks in this process that cannot be ignored.

[0003] First, magnesium powder is highly active and can easily undergo oxidation reactions with oxygen in the air. Under certain conditions, this oxidation reaction can become extremely violent, releasing a large amount of heat. Once the heat accumulates to a certain level, it is very likely to cause combustion, and in severe cases, it can even lead to explosions, which poses a huge threat to the production environment and personnel safety.

[0004] Therefore, in order to reduce the risk of combustion, existing magnesium powder pneumatic conveying devices usually change the gas source from ordinary air to inert gas, such as nitrogen, etc. By using inert gas as the conveying gas source, the chance of magnesium powder contacting oxygen can be effectively reduced, thereby greatly reducing the possibility of combustion.

[0005] However, even if such measures are taken, this method of transportation will still face the problem of easy pipe blockage. In the process of magnesium powder processing, the magnesium powder must first be fed into the grinding device for grinding. However, since the quality of the raw materials entering the grinding device is difficult to guarantee, there may be large particles of impurities or uneven materials, so it is easy to block the feeding port of the grinding device. Once the feeding port is blocked, it will not only affect the progress of grinding, but also cause equipment damage and increase maintenance costs. At the same time, the cleaning work after blockage is also cumbersome and requires a lot of time and manpower. Summary of the invention

[0006] The invention provides a conveying fire prevention device for magnesium powder grinding, which solves the problem that a feeding port of a grinding device in a conveying device in the related art is difficult to clean and dredge after being blocked.

[0011] Optionally, it also includes: A linkage ring is provided, wherein the linkage ring passes through the other ends of the third connecting rods and is relatively slidably arranged on the outside of the extended end of the second telescopic member.

[0012] Optionally, it also includes: A rotating baffle, one end of which is rotatably disposed at the first feed inlet, and after the rotating baffle is rotated, the first feed inlet is closed or opened; A first elastic member, wherein both ends of the first elastic member are respectively hinged to the rotating baffle and the first feed port, and is used to provide a force for resetting the rotating baffle.

[0016] Optionally, the feeding pipeline further includes: A filter device, one end of which is connected to the storage tank, and the other end of which is connected to the nitrogen gas source.

[0017] The working principle and beneficial effects of the present invention are: In the present invention, in order to solve the problem that the feeding port of the grinding device in the conveying device in the related art is difficult to clean and dredge after being blocked, a conveying fire prevention device for magnesium powder grinding is designed. In the actual magnesium powder grinding production line, the feeding pipeline is made of high-strength and corrosion-resistant materials to ensure that no damage will occur during the long-term transportation of magnesium powder. The first feeding port is set at a higher position, which is convenient for connecting with the upstream magnesium powder supply equipment, and the magnesium powder enters the first feeding port through gravity or auxiliary conveying equipment. The first branch pipeline can be branched according to actual needs. The design of the first elbow portion adopts a reasonable bending radius, which not only ensures the smooth flow of materials, but also reduces the friction and damage to the magnesium powder. When it is found that the first elbow portion in the feeding pipeline is blocked or needs to be cleaned regularly, the operator starts the first telescopic member through the control system. The first telescopic member can be an electric push rod, a hydraulic rod, etc., with sufficient thrust and stability. One end of the first telescopic member is firmly mounted on the end of the first branch pipeline away from the first elbow portion to ensure that there will be no loosening or displacement during the pushing process. The first connecting rod is made of high-strength metal material, and one end is connected to the extended end of the first telescopic member by a hinge, so that it can rotate flexibly during the pushing process. The cleaning device is usually in a standby state. When cleaning is required, the first telescopic member extends to push the first connecting rod, thereby driving the cleaning device to move toward the first curved pipe part. After the first abutting part of the cleaning device abuts against the inner wall of the feeding pipeline, due to the shape of the first abutting part, the cleaning device can slide toward the first curved pipe part, ensuring that the residual magnesium powder can be effectively cleaned when entering the first curved pipe part. After the cleaning device enters the first curved pipe part, the magnesium powder attached to the inner wall of the curved pipe is cleaned off by rotation, scraping, etc., and enters the grinding device together with the subsequent material transportation.

[0018] The advantage is that in the magnesium powder grinding production process, magnesium powder is prone to accumulation in the bend of the feeding pipeline, which not only affects the material transportation efficiency, but also poses a safety hazard. If the internal debris of the pipeline is manually cleaned after being blocked, a large amount of nitrogen inside the equipment will be wasted during the cleaning process, causing resource damage. By setting up a special cleaning device, the magnesium powder residue in the bend can be cleaned up in a timely and effective manner to ensure the unobstructed transportation pipeline, while also avoiding the leakage of nitrogen and reducing production costs. At the same time, the automated operation of the cleaning device can reduce the labor intensity and safety risks of manual cleaning, and improve the safety and reliability of production. In addition, the design of the first branch pipeline can realize the flexible distribution of materials, adapt to different production needs, and improve the flexibility and adaptability of the production line.

[0025] Reference Figure 1 to Figure 10 , which is the first embodiment of the present invention, proposes a conveying fire prevention device for magnesium powder grinding, which is used for feeding and unloading of a grinding device 1, and includes a feeding pipeline 2, the feeding pipeline 2 having a first feeding port 21 and a first discharging port 22, and also having a first branch pipeline 23 and a first curved pipe portion 24, the first discharging port 22 is connected to the feeding port of the grinding device 1; one end of the first telescopic member 3 is arranged at an end of the first branch pipeline 23 away from the first curved pipe portion 24; one end of the first connecting rod 4 is hingedly arranged at the extended end of the first telescopic member 3; one end of a cleaning device 5 is hingedly connected to the other end of the first connecting rod 4, and the cleaning device 5 has a first abutting portion 51. After the first telescopic member 3 is extended, the cleaning device 5 approaches the first curved pipe portion 24, and after the first abutting portion 51 abuts against the inner wall of the feeding pipeline 2, the cleaning device 5 enters the first curved pipe portion 24.

[0026] In this embodiment, in order to solve the problem that the feeding port of the grinding device in the conveying device in the related art is difficult to clean and dredge after being blocked, a conveying fire prevention device for magnesium powder grinding is designed. In the actual magnesium powder grinding production line, the feeding pipeline 2 is made of high-strength and corrosion-resistant materials to ensure that no damage will occur during the long-term transportation of magnesium powder. The first feed port 21 is set at a higher position, which is convenient for connecting with the upstream magnesium powder supply equipment. The magnesium powder enters the first feed port 21 through gravity or auxiliary conveying equipment. The first branch pipeline 23 can be branched according to actual needs. The design of the first elbow 24 adopts a reasonable bending radius, which not only ensures the smooth flow of materials, but also reduces the friction and damage to the magnesium powder. When it is found that the first elbow 24 in the feeding pipeline 2 is blocked or needs to be cleaned regularly, the operator starts the first telescopic member 3 through the control system. The first telescopic member 3 can be an electric push rod, a hydraulic rod, etc., with sufficient thrust and stability. One end of the first telescopic member 3 is firmly mounted on the end of the first branch pipeline 23 away from the first elbow 24 to ensure that there will be 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 by a hinge, so that it can rotate flexibly during the pushing process. The cleaning device 5 is in a standby state at ordinary times. When cleaning is needed, the first telescopic member 3 extends to push the first connecting rod 4, thereby driving the cleaning device 5 to move toward the first curved pipe part 24. After the first abutting portion 51 of the cleaning device 5 abuts against the inner wall of the feeding pipeline 2, due to the shape of the first abutting portion 51, the cleaning device can slide toward the first curved pipe part 24, ensuring that the residual magnesium powder can be effectively cleaned when entering the first curved pipe part 24. After the cleaning device 5 enters the first curved pipe part 24, the magnesium powder attached to the inner wall of the curved pipe is cleaned off by rotation, scraping, etc., and enters the grinding device 1 together with the subsequent material transportation.

[0027] The advantage is that in the magnesium powder grinding production process, magnesium powder is easily accumulated at the bend of the feeding pipeline 2, which not only affects the material transportation efficiency, but also wastes a lot of nitrogen inside the equipment during the cleaning process, causing resource damage. By setting a special cleaning device 5, the magnesium powder residue at the bend can be cleaned up in a timely and effective manner to ensure the unobstructed transportation pipeline, while also avoiding the leakage of nitrogen and reducing production costs. At the same time, the automated operation of the cleaning device 5 can reduce the labor intensity and safety risks of manual cleaning, and improve the safety and reliability of production. In addition, the design of the first branch pipeline 23 can realize the flexible distribution of materials, adapt to different production needs, and improve the flexibility and adaptability of the production line.

[0028] Furthermore, the cleaning device 5 includes an outer shell 52, the shape of which is adapted to the shape of the first curved pipe portion 24, one end of the outer shell 52 is hinged to the first connecting rod 4 away from one end of the first telescopic member 3, and the first abutment portion 51 is located at the other end of the outer shell 52; one end of the second telescopic member 53 is arranged in the outer shell 52, and after the second telescopic member 53 is extended, the extended end of the second telescopic member 53 is close to the first abutment portion 51, and the extended end of the second telescopic member 53 is flexible and adapted to the shape of the outer shell 52; the cleaning member 54 is arranged at the extended end of the second telescopic member 53, and after the second telescopic member 53 is extended, the cleaning member 54 extends out of the outer shell 52 and abuts against the inner wall of the feeding pipeline 2.

[0029] In this embodiment, the shape of the shell 52 of the cleaning device 5 is fully adapted to the first elbow portion 24. The second telescopic member 53 can be an electric push rod, a hydraulic rod or a pneumatic rod, etc., with an adjustable extension length and sufficient thrust. One end of the second telescopic member 53 is fixed in the shell 52, and its extension and retraction can be accurately controlled by the control system. When cleaning is required, the second telescopic member 53 is extended to push the extended end of the second telescopic member 53 to move toward the first abutment portion 51. The extended end of the second telescopic member 53 is made of flexible material, such as rubber, silicone, etc., which can fully adapt to the shape of the shell 52 and avoid damage to the inner wall of the pipeline during the cleaning process. The cleaning member 54 is arranged at the extended end of the second telescopic member 53. The cleaning member 54 can be in the form of a scraper, a brush, etc., and is selected according to actual needs. When the second telescopic member 53 is extended, the cleaning member 54 extends out of the shell 52, closely abuts against the inner wall of the feeding pipeline 2, and cleans the inner wall by rotating, scraping, etc. During the cleaning process, the cleaning member 54 can be adaptively adjusted according to the shape and condition of the inner wall of the pipeline to ensure maximum cleaning effect.

[0030] The advantage is that the shell 52 of the cleaning device 5 is adapted to the shape of the first curved pipe portion 24, which can ensure the comprehensiveness and effectiveness of the cleaning. The provision of the second telescopic member 53 allows the cleaning member 54 to be extended and retracted according to actual conditions, making the operation more flexible and convenient. The flexible extended end can avoid damage to the inner wall of the pipeline and extend the service life of the pipeline. The optional form and adaptive adjustment function of the cleaning member 54 can adapt to different pipeline conditions and cleaning requirements and improve the cleaning effect. This design can greatly improve the pipeline cleaning efficiency in the magnesium powder grinding production process, reduce production interruptions and equipment failures caused by pipeline blockage or magnesium powder residue, reduce production costs, and improve production efficiency.

[0031] Further, the cleaning member 54 includes a first rotating ring 541, which is rotatably arranged on the inner side of one end of the housing 52 having the first abutting portion 51, and the first rotating ring 541 has a first clamping portion 5411; a second rotating ring 542 is rotatably arranged on the extended end of the second telescopic member 53, and the second rotating ring 542 has a plurality of first mounting portions 5421; a plurality of first connecting rods 543, one end of the first connecting rod 543 is hinged to the first mounting portion 5421; one end of the second connecting rod 544 is hinged to the other end of the first connecting rod 543, and the first connecting rod 543 and the second connecting rod 544 are hinged at the hinged joint. It has a first cleaning portion 5441; the third connecting rod 545 is slidably arranged in the outer shell 52, one end of the third connecting rod 545 is hinged to the other end of the second connecting rod 544, and the third connecting rod 545 has a first plug-in portion 5451. After the first rotating ring 541 rotates, the first clamping portion 5411 abuts against or releases the abutment with the first plug-in portion 5451; the two ends of the second elastic member 55 respectively abut against one end of the first connecting rod 543 close to the first mounting portion 5421 and one end of the second connecting rod 544 close to the third connecting rod 545, so as to provide a force for moving one end of the first connecting rod 543 and one end of the second connecting rod 544 away from each other.

[0032] In this embodiment, when it is necessary to clean the inner wall of the pipeline, the control system is first started to extend the second telescopic member 53. The second telescopic member 53 adopts a device such as an electric push rod or a hydraulic rod, and has a stable extension power. As the second telescopic member 53 is extended, the second rotating ring 542 connected thereto and the first connecting rod 543 and the second connecting rod 544 installed on the second rotating ring 542 are driven to extend out of the housing 52. Then, the first rotating ring 541 is rotated. When the first rotating ring 541 is rotated, the first clamping portion 5411 on it gradually abuts against the first plug-in portion 5451 on the third connecting rod 545. In the abutting state, the third connecting rod 545 cannot slide in the housing 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 abutment between the first clamping portion 5411 and the first plug-in portion 5451, the first connecting rod 543 and the second connecting rod 544 are forced to fold. This folding makes the first cleaning part 5441 at the hinge of the first connecting rod 543 and the second connecting rod 544 tightly abut against the inner wall of the pipeline. It can effectively clean impurities such as magnesium powder residue on the inner wall of the pipeline. Subsequently, the first rotating ring 541 is continuously rotated. During the rotation process, due to the connection relationship between the first clamping part 5411 and the first plug-in part 5451, the entire cleaning structure is driven to rotate, so that the first cleaning part 5441 can comprehensively clean various parts of the inner wall of the pipeline. When the cleaning work is completed and the cleaning member 54 needs to be recovered, the second telescopic member 53 is first extended. At this time, the first connecting rod 543 and the second connecting rod 544 are separated 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., and has good elastic restoring force. Then, the first rotating ring 541 is rotated in the opposite direction to release the abutment state between the first clamping part 5411 and the first plug-in part 5451. Finally, the second telescopic member 53 is retracted, and the cleaning member 54 is retracted into the housing 52 to wait for the next cleaning task.

[0033] The advantage is that the design structure of the cleaning member 54 has a high degree of flexibility and adaptability. Through the extension and contraction of the second telescopic member 53 and the rotation operation of the first rotating ring 541, the extension, folding, rotation and recovery of the cleaning member 54 can be accurately controlled to meet the cleaning needs of the inner wall of the pipeline with different pipe diameters and shapes. The foldable design of the first cleaning part 5441 allows the cleaning member 54 to be easily retracted into the shell 52 when not in use, reducing the occupied space and facilitating storage and transportation. At the same time, during the cleaning process, the folded first cleaning part 5441 can be closely abutted against the inner wall of the pipeline, improving the cleaning effect and ensuring the comprehensiveness and thoroughness of the cleaning. The cooperation of the first clamping part 5411 on the first rotating ring 541 and the first plug-in part 5451 on the third connecting rod 545, as well as the setting of the second elastic member 55, makes the operation of the cleaning member 54 more stable and reliable. During the cleaning process, the position of the cleaning structure can be effectively fixed to prevent loosening or displacement, thereby ensuring the smooth progress of the cleaning work.

[0034] Furthermore, the plurality of first mounting portions 5421 , the first connecting rod 543 , the second connecting rod 544 and the third connecting rod 545 are uniformly distributed along the circumference of the axis of the first rotating ring 541 .

[0035] In this embodiment, in the structural design of the cleaning member 54, a plurality of first mounting portions 5421 are evenly distributed on the second rotating ring 542, providing a stable support point for the installation of the first connecting rod 543, so as to ensure comprehensiveness and uniformity of cleaning. Since the connecting rod is evenly distributed on the circumference, the cleaning force can also be evenly distributed on the inner wall of the pipeline, avoiding the situation of excessive or insufficient local cleaning.

[0036] The advantage is that the circumferentially evenly distributed structural design ensures comprehensive and uniform cleaning and avoids the appearance of cleaning dead corners. The synergy between the connecting rods makes the cleaning force more uniform, improving the cleaning effect and quality. This design can greatly reduce the safety hazards and production problems caused by incomplete cleaning, extend the service life of the pipeline, and improve the stability and reliability of magnesium powder grinding production. At the same time, the evenly distributed cleaning force can also reduce damage to the inner wall of the pipeline and reduce equipment maintenance costs.

[0037] Furthermore, it also includes a linkage ring 546 , which penetrates the other ends of the third connecting rods 545 , and is relatively slidably arranged on the outside of the extended end of the second telescopic member 53 .

[0038] In the present embodiment, a linkage ring 546 is provided in the structure of the cleaning member 54, and the linkage ring 546 is made of a high-strength metal material and has good rigidity and wear resistance. The linkage ring 546 runs through the other ends of the plurality of third connecting rods 545, so that each of the third connecting rods 545 can move synchronously under the drive of the linkage ring 546. When the cleaning member 54 performs the cleaning operation, the linkage ring 546 can remain stable and does not affect the adjustment of the cleaning structure. After the cleaning work is completed, when the cleaning member 54 needs to be recovered, the second telescopic member 53 is first extended to make 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 do not fold. At this time, the linkage ring 546 can assist in keeping the third connecting rod 545 stable, preventing accidental folding or movement.

[0039] The advantage is that when the cleaning member 54 is recovered, the linkage ring 546 can help maintain the stability of the cleaning structure, prevent unexpected situations, and make the recovery process smoother and more reliable.

[0040] Furthermore, it also includes a rotating baffle 6, one end of which is rotatably set at the first feed port 21. After the rotating baffle 6 is rotated, the first feed port 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 port 21, so as to provide a force for resetting the rotating baffle 6. After the rotating baffle 6 is reset, the first feed port 21 is closed.

[0041] In this embodiment, in the fire-proof device for conveying magnesium powder grinding, in order to prevent nitrogen waste, a special closing structure is provided at the first feed port 21. The closing structure is mainly composed of a rotating baffle 6 and a first elastic member 7. The rotating baffle 6 is made of a high-strength, corrosion-resistant and well-sealed material, and one end is rotatably arranged at the first feed port 21 through a hinge. When magnesium powder raw materials need to enter the feeding pipeline 2, the impact force of the material overcomes the elastic force of the first elastic member 7, so that the rotating baffle 6 opens, and the material smoothly enters the first feed port 21. The first elastic member 7 can be a spring, elastic rubber, etc., and the two ends are hinged to the rotating baffle 6 and the first feed port 21 respectively. Once the material has entered, the elastic force of the first elastic member 7 quickly resets the rotating baffle 6 and closes the first feed port 21. During the grinding and conveying process of magnesium powder, the entire device is filled with nitrogen. In this environment, if there is no effective closing measure for the first feed port 21, nitrogen will escape in large quantities, resulting in a waste of resources. The design of the rotating baffle 6 can be opened at the moment of material entry and remain closed for the rest of the time, effectively shortening the opening time of the first feed port 21 and greatly reducing the waste of nitrogen. In order to further improve the sealing effect, a sealing gasket can be provided at the contact portion between the rotating baffle 6 and the first feed port 21 to ensure that nitrogen does not leak in the closed state. At the same time, the opening and closing of the rotating baffle 6 can be precisely controlled by the control system, and the state of the baffle can be adjusted in time according to the needs of material transportation.

[0042] The advantage is that by setting the rotating baffle 6 and the first elastic member 7, the problem of nitrogen waste during the grinding and transportation of magnesium powder is effectively solved. The rotating baffle 6 can be quickly opened when the material enters, and quickly closed after entering, which greatly shortens the opening time of the first feed port 21, reduces the amount of nitrogen escape, saves resources, and reduces production costs. Good sealing performance ensures the stability of the nitrogen environment in the equipment and improves the safety of the magnesium powder grinding and transportation process. The setting of the sealing gasket further enhances the sealing effect, prevents nitrogen leakage, and provides a more reliable guarantee for the production process.

[0043] Furthermore, it also includes a feed discharge pipeline 8, which is connected to the discharge port of the grinding device 1.
