Description

Technical Field

[0001] The present invention relates to the technical field of air locks, in particular to an air lock with anti-blocking and self-cleaning functions. Background Art

[0002] An air shutoff, also known as a blower, discharge valve, ash discharge valve, or star discharger, is a crucial device in pneumatic conveying and ventilation dust removal networks. Its primary function is to continuously and promptly discharge material from the discharger while preventing outside air from entering the discharger or dust collector. The blower consists of a housing and an impeller. The impeller's shaft rotates within the housing, and the impeller's edge is sealed against the inner wall of the housing.

[0003] After long-term use of traditional air locks, materials are easily accumulated on the impeller blades, which cannot be removed by rotation alone, resulting in continuous accumulation of materials. Once the materials accumulate too much, the materials accumulated on the blades will contact the inner wall of the air lock shell, thereby blocking the inner cavity of the air lock and making the air lock unable to operate normally. The traditional air lock is more troublesome to disassemble, resulting in a long time spent on cleaning the materials on the blades each time. Summary of the Invention

The arc grooves 74 are used to resist the first roller 042.

[0067] In this embodiment, when the air lock is working, the material enters the interior from the top feed port of the shell 01, and the material entering the shell 01 falls by its own weight and fills the gap between the blades 0102. As the drive motor 07 cooperates with the impeller shaft 0101 to drive the blades 0102 to rotate, the material is discharged from the discharge port at the bottom of the shell 01. After the air lock has been used for a period of time, the operator can clean the impeller mechanism 010 of the air lock and remove the material attached to the blades 0102 to prevent it from causing blockage.

[0068] First, drive the first electric cylinder 031, and the piston rod of the first electric cylinder 031 extends, pushing the first sliding base 032 to slide on the first slide rail 033. Under the action of the side shell connecting frame 8, the drive motor 07 and the side shell 09 are driven to move at the same time. The side shell 09 begins to separate from the side shell socket 011, and the slider 092 slides in the slide groove 012, thereby realizing the extraction of the entire impeller mechanism 010 from the shell 01. Before extraction, the connected machine is ensured to stop working, and the drive motor 07 stops rotating.

[0069] When the driving motor 07 stops rotating, the locking unit 3 of the cleaning mechanism is attached to the inner wall of the shell 01, and the second roller 33 is squeezed by the inner wall of the shell 01, so that the limiting plug 311 is inserted into the limiting socket 14. As the side shell 09 is pulled out, the locking unit 3 of the cleaning mechanism is no longer restricted by the inner wall of the shell 01, and the first spring 35 releases its elastic potential energy to reset, thereby pushing the sliding block 32 to slide on the first slide rod 34, pushing the limiting socket 31, and realizing the separation of the limiting plug 311 from the limiting socket 14, thereby releasing the locking of the cleaning mechanism. Unit 3 locks the state of the impeller cleaning mechanism 1. The cleaning mechanism locking unit 3 is used to lock the impeller cleaning mechanism 1 when cleaning is not required to prevent it from escaping from the cleaning mechanism receiving groove 22. When the side shell 09 moves back to the inside of the shell 01, as the second roller 33 is released from the inner wall of the shell 01, the second roller 33 will be squeezed and compressed into the active cavity 23 of the locking unit, so that the limit socket 31 moves on the first slide rod 34, and the limit plug plate 311 is reinserted into the limit socket 14, entering the locked state, and at the same time the first spring 35 deforms and contracts.

[0070] When the first electric cylinder 031 is fully extended, the side shell 09 has been completely pulled out of the shell 01. At this time, the impeller mechanism 010 is completely located above the collection box 08, and automatic cleaning begins at this time. The second electric cylinder 041 starts working after the first electric cylinder 031 stops. The piston rod of the second electric cylinder 041 extends to achieve the extension of the first roller 042. After the first roller 042 is extended, it slowly contacts the bottom of the inclined portion 511. As the first roller 042 continues to extend, the first roller 042 continues to squeeze the inclined portion 511, so that the fixed block 51 is squeezed. Afterwards, the telescopic rod 42 is driven to extend downward from the telescopic sleeve 41, and the telescopic rod slider 43 maintains vertical linear movement in the inner cavity of the telescopic sleeve 41, thereby realizing the descending of the cleaning mechanism connecting frame 5, and in the descending process, the third roller 54 is always in contact with the first limit plate 0521, and the third roller 54 is against the vertical plate surface of the L-shaped first limit plate 0521, limiting the movement of the cleaning mechanism connecting frame 5, ensuring that the cleaning mechanism connecting frame 5 remains in a vertical descending state at this time, preventing the second sliding base 45 from sliding when pushed by the first roller 042.

[0071] As the cleaning mechanism connecting frame 5 descends, the limiting block 52 slowly descends to the connecting block 13, and the slot 53 cooperates with the limiting slot 131 to achieve that the limiting block 52 clamps the impeller cleaning mechanism 1, and the third roller 54 is no longer restricted by the first limiting plate 0521. At this time, after the first roller 042 continues to extend, it will push the fixed block 51 to move horizontally, thereby realizing that the top second sliding base 45 slides on the slide rail seat 051.

[0072] And when the first roller 042 squeezes and pushes the fixed block 51, the roller limiting block 73 will be stuck on the first roller 042 as the fixed block 51 moves vertically, and the sliding plate 71 slides on the second slide rod 62, cooperating with the third spring 64, so that the roller limiting block 73 can be flexibly moved, and after the fixed block 51 drops, the first roller 042 contacts the roller limiting block 73, and can be stuck on the first roller 042, so that the arc groove 74 is in contact with the first roller 042, and as the cleaning mechanism connecting frame 5 moves horizontally, the limiting column 75 at this time will move under the bottom plate of the second limiting plate 0531.

[0073] After the cleaning mechanism connecting frame 5 moves horizontally, the limiting block 52 pulls the impeller cleaning mechanism 1 from the movable position in the cleaning mechanism receiving groove 22, causing the impeller cleaning scraper 12 to slide on the blade 0102. At the same time, the impeller cleaning scraper 12 loosens the material slightly attached to the blade 0102, so that the material no longer adheres to the blade 0102, and the blade 0102 is cleaned. When the impeller cleaning scraper 12 is pushed horizontally to the side disc 2 on the other side, the second electric cylinder 041 contracts, and when the first roller 042 contracts, the first roller 042 moves in the opposite direction, pushing the roller limiting block 73. Because the limiting column 75 is supported by the second limiting plate 0531, when the roller limiting block 73 is pushed by the first roller 042, the sliding plate 71 does not slide upward. Instead, it only drives the entire cleaning mechanism connecting frame 5 to move, and the second sliding base 45 moves toward the cleaning mechanism receiving groove 22.

[0074] When the first roller 042 is pushed again, the contraction of the first roller 042 pushes the sliding plate 71 upward, thereby realizing that the first roller 042 is released from contact with the fixed block 51, and the third spring 64 releases its elastic potential energy to ensure that the sliding plate 71 can be reset. After the first roller 042 is reset, the fixed block 51 is no longer squeezed by the first roller 042, realizing that the second spring 44 releases its elastic potential energy, driving the bottom fixed block 51 to rise, and the telescopic rod 42 retracts back into the telescopic sleeve 41, thereby realizing the rapid reset of the cleaning mechanism connecting frame 5, contacting the cleaning mechanism connecting frame 5 to clamp the impeller cleaning mechanism 1, completing the cleaning work of the impeller mechanism 010, and at this time the staff can sweep some of the materials that have not fallen on the blades 0102 into the bottom collection box 08, which is used to collect the materials scraped off by the impeller cleaning scraper 12.

[0075] In the present invention, by providing a side shell 09 in cooperation with the first drive mechanism 03, the impeller mechanism 010 can be separated from the shell 01 for cleaning, and the provided impeller cleaning mechanism 1 can scrape off the material attached to the blade 0102, and cooperate with the provided scraper clamping unit 06. After the impeller cleaning mechanism 1 moves into place, driven by the second drive mechanism 04, the cleaning mechanism connecting frame 5 can realize rapid clamping of the impeller cleaning mechanism 1, thereby realizing automatic cleaning, automatically scraping off the material on the blade 0102, effectively replacing manual cleaning of the air lock, and the impeller mechanism 010 can be cleaned without disassembling the shell 01. This air lock can be self-cleaned regularly to effectively prevent the air lock blades from being affected by the attached material and causing blockage.

[0076] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
