Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial equipment, in particular to an anti-blocking device for sintered ash feeding. Background Art
[0002] Sinter ash is a waste product generated during steel production, primarily from the electrostatic precipitator (ESP) of steelmaking sintering machines. Sinter ash contains elements such as iron, potassium, sodium, and zinc, and possesses considerable utility. Sinter ash can be processed to extract these valuable elements.
[0003] However, sintered ash easily absorbs moisture and clumps, which can easily cause blockage during material discharge during the production process. Utility Model Content
[0004] In view of this, the purpose of the present invention is to provide a sintered ash unloading anti-blocking device which can avoid the sintered ash from clogging and agglomerating during unloading in industrial production.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a sinter ash discharge anti-blocking device, including a discharge hopper and a conveying device;
[0006] The conveying device includes a conveyor belt, a conveying motor and a frame. The discharge port of the lower hopper is located above the conveyor belt. A vibration device is fixed on the outer wall of the lower hopper, and a dredging device is provided at the discharge port of the lower hopper.
[0007] The dredging device includes a dredging piece, which is a hook-shaped structure and can swing back and forth.
[0008] The beneficial effect of the above technical solution is that the vibration device can help the sintered ash in the hopper to be discharged by vibrating the hopper. When the sintered ash clumps and blocks the discharge port of the hopper, the dredging device can further dredge the discharge port, thereby avoiding the sintered ash being blocked and unable to discharge.
[0009] Furthermore, the dredging device includes a bracket, a rotating shaft and a driving assembly. The bracket is fixed on the frame of the conveying device, the top of the bracket is rotatably connected to the rotating shaft, the dredging piece is fixed on the rotating shaft, and the driving assembly is transmission-connected to the rotating shaft.
[0010] Beneficial effects: the bracket is fixed on the frame more stably, and the driving component can drive the rotating shaft to drive the dredging piece to swing back and forth to dredge the discharge port.
[0011] Furthermore, the driving assembly includes a first cam, a second cam and a driving motor. The first cam is fixed at the end of the rotating shaft. The second cam is arranged to rotate laterally of the first cam. The raised portion of the second cam can periodically contact the raised portion of the first cam. The second cam is fixed on the driving shaft of the driving motor.
[0012] Beneficial effect: The second cam can periodically drive the first cam to rotate. When the second cam protrusion contacts the first cam protrusion, the first cam swings. When the second cam protrusion leaves the first cam, the first cam can be reset due to the gravity of the clearing piece on the rotating shaft, thereby realizing the clearing piece swinging back and forth.
[0013] Furthermore, the support is a gantry, and the bottom of the gantry is fixed on the frame on both sides of the conveyor belt.
[0014] Beneficial effects: ensuring the stability of the bracket and providing a better installation position for the dredging component.
[0015] Furthermore, the bracket is located behind the lower hopper relative to the material transporting direction.
[0016] Beneficial effect: Avoid the dredging parts from interfering with the transportation of sintered ash on the conveyor belt.
[0017] Furthermore, the rotation radius of the dredging member is smaller than the distance between the rotating shaft and the conveyor belt.
[0018] Beneficial effect: Prevents the dredging piece from hitting the conveyor belt when swinging.
[0019] Furthermore, the clearing piece is L-shaped, one end of the L-shaped clearing piece is fixedly connected to the rotating shaft, and the other end of the L-shaped clearing piece is a sharp structure, and the sharp structure is arranged in the direction toward the discharge port.
[0020] Beneficial effect: The sharp structure can quickly break up and clear the sintered ash when it agglomerates. BRIEF DESCRIPTION OF THE DRAWINGS
