Description

Technical Field

[0001] The utility model relates to the technical field of jet classifiers, and particularly relates to a feeding device for a jet classifier. Background Technique

[0002] The classifier body generally forms a set of classification system together with a cyclone separator, a filter collector, a draft fan, etc. The fine powder material is dispersed under the action of high-pressure gas and then enters the jet classifier body. Under the action of the Coanda effect, the fine particles cling to the Coanda block, the medium particles are in the middle part, and the large particles are far away from the Coanda block. In this way, the fine powder particles are instantly divided into three levels: fine, medium, and coarse, and then are respectively recovered in the downstream collector.

[0003] Due to the lack of protective measures in the traditional jet classifier, the material directly contacts the air during the feeding process, and when rotating, due to the opening of the feeding port, the material may be leaked. The inlet of the traditional feeding device usually directly pours the material at one time, but it may cause the equipment to be blocked. Therefore, we propose a feeding device for a jet classifier. Content of the Utility Model

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. For the feeding device of the jet classifier, by pressing the controller, the controller controls the motor, so that the motor can drive the gear, and then the gear can drive the rack to slide on the outer wall of the slide rail. At this time, the rack slides in the inner wall of the rectangular groove opened on the outer wall of the protective shell. When the rack slides, the rack can drive the rotating shaft to rotate, so that the rotating shaft can drive the material distribution plate to rotate in the inner wall of the round sleeve. At this time, the material distribution plate can feed materials evenly, thus avoiding equipment blockage caused by excessive pouring at one time and improving the working progress.

[0013] 2. For the feeding device of the jet classifier, by manually pulling up the cover plate, the cover plate can drive the limiting plate to lift and lower.

[0024] In the above structure, since the feeding port 4 is fixedly installed on the top of the outer shell 1, when the material enters the inner cavity of the feeding port 4, it can be fixed through the feeding port 4 and the outer shell 1, so that the material can enter the inner cavity of the outer shell 1 and be evenly fed by the material distribution component 7.

[0025] In a preferred embodiment: the outer wall of the feeding port 4 is fixedly installed with the outer wall of the square plate 501, a circular groove is opened in the inner wall of the fixed plate 6, and the steel ball 508 is clamped with the circular groove, a rectangular groove is opened in the outer wall of the protective shell 3, and the rack 702 is slidably connected to the rectangular groove.

[0026] In the above structure, a circular groove is formed in the inner wall of the fixing plate 6, and the steel ball 508 is engaged with the circular groove. When starting to work, the opening and closing assembly 5 is closed. At this time, the steel ball 508 can be engaged with the inner wall of the fixing plate 6, thereby preventing the material from being thrown out along the opening and closing assembly 5 when the machine is working.

[0027] In a preferred embodiment: The opening and closing assembly 5 includes a square plate 501. A cylinder 502 is fixedly installed on the inner wall of the square plate 501. A connecting plate 503 is rotatably connected to the outer wall of the cylinder 502. A long rod 504 is fixedly installed on the inner wall of the connecting plate 503. A cover plate 505 is fixedly installed on the outer wall of the long rod 504. A limiting plate 506 is fixedly installed on the outer wall of the cover plate 505. An elastic member 507 is fixedly installed on the inner wall of the limiting plate 506. A steel ball 508 is fixedly installed on the outer wall of the elastic member 507.

[0028] In a preferred embodiment: There are two groups of steel balls 508, and both groups of steel balls 508 are installed on the outer wall of the elastic member 507. The outer wall of the limiting plate 506 is in contact with the outer wall of the feeding port 4.

[0029] In the above structure, by pulling the cover plate 505, the cover plate 505 can drive the limiting plate 506 to move up and down. At this time, the steel ball 508 engaged with the inner wall of the fixing plate 6 is compressed by the force, thereby driving the elastic member 507 to be compressed, so that the limiting plate 506 can be disengaged from the inner wall of the fixing plate 6. At this time, the cover plate 505 can drive the long rod 504 to rotate the connecting plate 503 on the inner wall of the cylinder 502, so that the cover plate 505 can be opened at the top of the feeding port 4.

[0030] In a preferred embodiment: The material distribution assembly 7 includes a gear 701. A rack 702 is provided on the outer wall of the gear 701. A slide rail 703 is slidably connected to the outer wall of the rack 702. A tooth ring 704 is engaged with the outer wall of the rack 702. A rotating shaft 705 is fixedly installed on the inner wall of the tooth ring 704. A material distribution plate 706 is fixedly installed on the outer wall of the rotating shaft 705. A circular sleeve 707 is provided on the outer wall of the material distribution plate 706.

[0031] In the above structure, through

[0032] In a preferred embodiment: A motor is fixedly installed on the outer wall of the gear 701 close to the feeding port 4. The outer wall of the gear 701 is fixedly installed with the power output shaft of the motor, and the motor is electrically connected to the controller 2. A square groove is formed at the bottom of the slide rail 703, and the gear 701 is engaged with the rack 702 through the square groove. The bottom of the material distribution plate 706 is slidably connected to the inner wall of the circular sleeve 707. A square groove is formed on the outer wall of the circular sleeve 707 close to the feeding port 4.

[0033] In the above structure, when the motor starts to work, the motor can drive the gear 701, so that the gear 701 can drive the rack 702 to slide on the outer wall of the slide rail 703. When the rack 702 slides, the rack 702 can drive the rotating shaft 705 to rotate. Since the rotating shaft 705 is fixedly installed on the inner wall of the gear ring 704, the rotating shaft 705 can drive the material distribution plate 706 to rotate on the inner wall of the circular sleeve 707. At this time, the material distribution plate 706 can feed the material evenly.

[0034] Working principle: By pulling the cover plate 505, the cover plate 505 can drive the limit plate 506 to move up and down. At this time, the steel balls 508 clamped with the inner wall of the fixed plate 6 are compressed under force, thereby driving the elastic member 507 to be compressed, so that the limit plate 506 can be disengaged from the inner wall of the fixed plate 6. At this time, the cover plate 505 can drive the long rod 504 to rotate the connecting plate 503 on the inner wall of the cylinder 502, so that the cover plate 505 can be opened at the top of the feeding port 4. At this time, feeding can be carried out. Since the feeding port 4 is fixedly installed on the top of the housing 1, when the material enters the inner cavity of the feeding port 4, it can be fixed to the housing 1 through the feeding port 4, so that the material can enter the inner cavity of the housing 1 and be fed by the material distribution assembly 7. When the motor starts to work, the motor can drive the gear 701, so that the gear 701 can drive the rack 702 to slide on the outer wall of the slide rail 703. When the rack 702 slides, the rack 702 can drive the rotating shaft 705 to rotate. Since the rotating shaft 705 is fixedly installed on the inner wall of the gear ring 704, the rotating shaft 705 can drive the material distribution plate 706 to rotate on the inner wall of the circular sleeve 707. At this time, the material distribution plate 706 can feed the material evenly.
