Description

Technical Field

[0001] The present application relates to the technical field of cleaning mechanisms, and more specifically, to an inner cavity cleaning mechanism for a wet mixer. Background Art

[0002] Vanadium-nitrogen alloy raw material is a new type of alloy additive, which is mainly made of vanadium pentoxide, carbon powder, activator and other raw materials. It can replace ferrovanadium in the production of micro-alloyed steel. Therefore, the above raw materials need to be stirred and mixed by a wet mixer during the production process.

[0003] When the vanadium-nitrogen alloy raw materials are mixed by a wet mixer, since the vanadium-nitrogen alloy is easy to adhere to the inner cavity of the wet mixer, after the vanadium-nitrogen alloy is mixed, the inner cavity of the wet mixer needs to be cleaned by a cleaning mechanism to avoid affecting the secondary use.

[0004] The inventors have found that most of the existing wet mixer cavity cleaning mechanisms are external cleaning mechanisms. After the wet mixer finishes mixing, the inner cavity of the wet mixer is cleaned. The external cleaning mechanism usually needs to be moved to the side of the wet mixer after the wet mixer has been used for a period of time, and then its inner cavity is cleaned. The vanadium-nitrogen alloy that has not been cleaned for a long time will appear agglomerates, and it is difficult to clean the vanadium-nitrogen alloy in time before agglomerates after one stirring and mixing is completed. After the agglomerated vanadium-nitrogen alloy adheres to the inner cavity of the wet mixer, the cleaning difficulty and cleaning efficiency of the inner cavity will be greatly increased, which will affect the secondary use of the wet mixer.

The structures of the first protrusion 405 and the second protrusion 407 cooperate with each other. Each scraper 402 is elastically connected to the fixed plate 403 through a first spring 409. When scraping off the vanadium-nitrogen alloy raw material adhered to the inner wall of the stirring tank 201, the fixed rod 210 drives the scraper 401 to rotate, so that while stirring the vanadium-nitrogen alloy raw material, the scraper 401 will scrape off the raw material adhered to the inner wall of the stirring tank 201 by rotating itself. The scraper 402 and the transmission rod 404 are synchronously driven to rotate by the rotation of the scraper plate 401, so that the transmission rod 404 synchronously drives the first protrusion 405 to rotate at the bottom end of the fixed plate 406, and through the engagement between the first protrusion 405 and the second protrusion 407, when the first protrusion 405 is in a rotating state and the second protrusion 407 is in a stationary state, when the top of the first protrusion 405 contacts the top of the second protrusion 407, the first protrusion 405 drives the transmission rod 404 to move downward along the outer wall of the scraper 402, and the downward movement of the transmission rod 404 synchronously drives the scraper 402 to move downward, and when the scraper 402 moves downward, the first spring 409 on the inner wall of the fixed plate 403 is pressed. The scraper 401 is compressed until the top of the first protrusion 405 gradually loses contact with the bottom of the second protrusion 407. The first spring 409 pushes the scraper 402 to move upward through its own elasticity, and then the scraper 401 rotates so that the scraper 402 is in a state of repeated up and down movement. The reciprocating motion of the scraper 402 synchronously realizes the reciprocating motion of the cutting groove 408, so that after the scraper 401 scrapes off the vanadium-nitrogen alloy raw material on the inner wall of the stirring tank 201, part of the vanadium-nitrogen alloy raw material will adhere to the surface of the scraper 401, and the reciprocating motion of the cutting groove 408 will cut off the adhered raw material up and down, thereby improving the cleanliness of the scraper 401 when cleaning the inner cavity of the stirring tank 201, and ensuring the effect of cleaning the vanadium-nitrogen alloy.

The rotation of the first stirring rod 205 and the second stirring rod 207 realizes the mixing and stirring of the vanadium-nitrogen alloy raw materials. After the vanadium-nitrogen alloy is mixed, the discharge valve 208 is opened, and the vanadium-nitrogen alloy stirred in the stirring tank 201 is discharged through the discharge port, the discharge valve 208 and the discharge channel 209.

[0051] Then, when scraping off the vanadium-nitrogen alloy raw material adhered to the inner wall of the stirring tank 201, the scraper 401 is driven to rotate by the fixed rod 210, so that while the vanadium-nitrogen alloy raw material is being stirred, the scraper 401 will scrape off the raw material adhered to the inner wall of the stirring tank 201 by its own rotation, and through the rotation of the scraper 401, the scraper blade 402 and the transmission rod 404 are synchronously driven to rotate, so that the transmission rod 404 synchronously drives the first protrusion 405 to rotate at the bottom end of the fixed plate 406, and through the engagement between the first protrusion 405 and the second protrusion 407, when the first protrusion 405 is in a rotating state and the second protrusion 407 is in a stationary state, when the top of the first protrusion 405 contacts the top of the second protrusion 407, the first protrusion 405 will drive the transmission rod 404 to move downward along the outer wall of the scraper blade 402, and through the downward movement of the transmission rod 404 , synchronously driving the scraper 402 to move downward, and while the scraper 402 moves downward, compressing the first spring 409 on the inner wall of the fixed plate 403, until the top of the first protrusion 405 gradually loses contact with the bottom of the second protrusion 407, the first spring 409 itself The elasticity will push the scraper 402 to move upward, and then through the rotation of the scraper 401, the scraper 402 is in a state of repeated up and down movement, and through the reciprocating motion of the scraper 402, the reciprocating motion of the cutting groove 408 is synchronously realized, so that after the scraper 401 scrapes off the vanadium-nitrogen alloy raw material on the inner wall of the stirring tank 201, part of the vanadium-nitrogen alloy raw material will adhere to the surface of the scraper 401, and through the reciprocating motion of the cutting groove 408, the adhered raw material is cut off up and down, thereby improving the cleaning performance of the scraper 401 when cleaning the inner cavity of the stirring tank 201, ensuring the effect of cleaning the vanadium-nitrogen alloy.

[0052] Secondly, when it is necessary to clean the inner cavity of the mixing tank 201, the micro motor 501 is started, and the output shaft of the micro motor 501 is used to control the driving gear 511 to rotate, so that when the driving gear 511 is meshed with the rack 502, the rack 502 is synchronously driven to move, and the rack 502 moves, and the moving door 512 is synchronously driven to slide on the bottom wall inside the dark groove 506. When the moving door 512 completely opens the bottom of the fixed rod 210, the rack 502 is synchronously meshed with the driven gear 510, and the driven gear 510, the second rotating shaft 504, the second belt 505, the first rotating shaft 503 and the meshing gear 508 are synchronously driven to rotate through the movement of the rack 502, so that when the meshing gear 508 rotates, it synchronously drives the toothed plate 507 to move downward. , thereby making the high-pressure nozzle 308 move downward synchronously under the drive of the tooth plate 507, and through the downward movement of the high-pressure nozzle 308, the sliding rod 513 is synchronously driven to slide downward inside the sliding groove 514. At the same time, the bellows 307 itself is stretched, and through the downward sliding of the sliding rod 513, the second spring 515 is synchronously compressed and deformed until the water outlet end of the high-pressure nozzle 308 is completely moved out of the interior of the fixed rod 210, so as to facilitate the subsequent cleaning of the inner cavity of the stirring tank 201. By prefabricating the high-pressure nozzle 308 inside the stirring mechanism 2, the inside of the stirring tank 201 can be cleaned in real time after the stirring of the vanadium-nitrogen alloy raw material is completed, so as to avoid the vanadium-nitrogen alloy raw material from adhering to the inside of the stirring tank 201 for a long time and then agglomerating, which increases the difficulty and effect of subsequent cleaning.

[0053] Finally, when cleaning the interior of the mixing tank 201, start the water pump 302, and use the water pump 302 to transport the water inside the water tank 301 to the interior of the high-pressure nozzle 308 through the cooperation of the water pump pipe 304, the water outlet pipe 303, the rotary joint 305, the water pipe 306 and the bellows 307. When the transmission shaft 206 drives the water pipe 306 to rotate at the bottom end of the rotary joint 305, the high-pressure nozzle 308 rotates synchronously inside the mixing tank 201, thereby improving the cleaning effect of the high-pressure nozzle 308 when performing high-pressure cleaning on the adhered vanadium-nitrogen alloy inside the mixing tank 201.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
