Description

Technical Field

[0001] This utility model relates to the field of fly ash hopper feeding technology, and in particular to a feeding structure and its vertical fly ash hopper. Background Technology

[0002] Fly ash is a type of solid waste discharged from coal-fired power plants. It can be reused to obtain more economic value. Before reuse, fly ash needs to be collected and processed centrally. During this process, it needs to be stored through discharge pipes. Fly ash storage tanks on the market are generally vertical.

[0003] In the currently used vertical fly ash storage tanks, fly ash may clump together near the discharge port due to its own gravity, causing blockages. In addition, in high humidity environments, the moisture content in fly ash may increase, leading to particle adhesion and the formation of lumps, resulting in abnormal discharge.

[0004] Therefore, those skilled in the art have provided a feeding structure and a vertical fly ash silo thereof to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding structure and its vertical fly ash silo, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding structure includes: a circular ring column, the bottom end of the outer wall of the circular ring column having a locking groove, a limiting frame fixedly installed in the locking groove, a movable plate unit movably engaging in the cavity of the limiting frame, and a cylinder for pushing the movable plate unit provided on one side of the limiting frame; a dispersing mechanism, the dispersing mechanism being fixedly installed on the outer wall of the circular ring column, the dispersing mechanism including a dispersing unit for dispersing powder lumps, an angle adjustment part for rotating the dispersing unit, and a lifting part for lifting the dispersing unit; the dispersing unit including a drive motor and a dispersing rod, the drive motor driving the dispersing rod to rotate, the angle adjustment part including a rotating rod and a second servo motor, the lifting part including a rectangular frame, a lead screw and a lifting plate, the rectangular frame being fixedly installed on the outer wall of the circular ring column, the lifting plate movably engaging in the cavity of the rectangular frame, the lead screw movably penetrating through the lifting plate, and the lead screw and the lifting plate being in a transmission cooperation.

[0008] According to the feeding structure, the movable plate unit includes a baffle and a movable plate, which are fixedly connected. The side of the baffle closest to the annular column is semi-circular, and a fixing block and a limiting block are fixedly installed on the top of the movable plate.

[0009] According to the feeding structure, the fixing block is located at the middle position of the top of the moving plate, the telescopic end of the cylinder is fixedly connected to the fixing block, the limiting block is located at both ends of the moving plate, the limiting block is L-shaped, and the limiting block is engaged with the limiting frame.

[0010] According to the feeding structure, the lead screw is movably installed inside the rectangular frame cavity, and a first servo motor is fixedly installed at the top of the rectangular frame. The output shaft of the first servo motor movably passes through the rectangular frame and is fixedly connected to one end of the lead screw.

[0011] According to the feeding structure, a cylindrical tube is fixedly connected between the drive motor and the rotating rod, and a reinforcing rod is fixedly installed between the cylindrical tube and the rotating rod. The rotating rod is T-shaped, and the lifting plate and the lead screw are perpendicular to each other.

[0012] According to the feeding structure, a rotating groove is provided on one side of the lifting plate, and a rotating rod is movably installed in the rotating groove. A second servo motor is fixedly installed on the outer wall of one side of the lifting plate. The output shaft of the second servo motor fixes the rotating rod, and the second servo motor drives the rotating rod to rotate.

[0013] A vertical fly ash silo includes a silo body and the aforementioned feeding structure, with a circular column fixedly installed at the feeding port at the bottom of the silo body.

[0014] This utility model provides a feeding structure and a vertical fly ash silo. It has the following beneficial effects:

[0015] (1) By fixing a circular column at the discharge port of the tank, a limiting frame, a moving plate unit and a cylinder are set on the outer wall of one side of the circular column. The cylinder pushes the moving plate unit to move and controls the amount of material discharged through the circular column. Fly ash may clump together near the discharge port of the tank due to its own gravity, causing blockage. By setting a dispersing mechanism on the outer wall of the circular column, the dispersing unit can disperse the fly ash and clear the blockage. The lifting part can adjust the height of the dispersing unit to improve the practicality of the device. The angle adjustment part can rotate the dispersing unit and move the dispersing unit out of the circular column cavity. The practicality of the device is improved through reasonable structural design.

The extension end of the cylinder is fixedly connected to the fixed block. The cylinder pushes the fixed block, and the fixed block drives the moving plate, the baffle and the limiting block to move synchronously. The baffle moves to the end and is located in the cavity of the annular column, thereby preventing the fly ash from being discharged. The limiting block plays a limiting and guiding role for the baffle.

[0017] (3) A rectangular frame is fixedly installed on the outer wall of the annular column. The first servo motor drives the lead screw to rotate during operation. The lead screw moves through the lifting plate, thereby driving the lifting plate to move up and down. A rotating groove is opened on one side of the lifting plate. The rotating rod is movably installed in the rotating groove. A cylindrical tube is fixedly connected between the rotating rod and the drive motor. During the lifting process, the drive motor is driven to move up and down synchronously. A second servo motor is fixedly installed on the outer wall of the lifting plate. The output shaft of the second servo motor is fixed to the rotating rod. The second servo motor drives the rotating rod to rotate. The rotating rod drives the drive motor to rotate 180 degrees through the cylindrical tube, so that the drive motor and the disintegrating rod are located below the annular column.
