Description

Technical Field

[0001] The utility model belongs to the technical field of calcium aluminate powder production, in particular to a feeding mechanism used for calcium aluminate powder production screening. Background Art

[0002] Calcium aluminate powder is a raw material used to prepare water purifiers. Calcium aluminate powder is made by crushing, drying, ball milling, billeting, calcining, screening, and grinding high-grade bauxite and limestone. When calcium aluminate powder is fed to the screening device after grinding, a screw conveyor is required. However, the screw conveyor is easily affected by the vibration of the screening device, which is not conducive to long-term safe operation. In addition, the discharge points of the screw conveyor are relatively concentrated, which is not conducive to improving the working efficiency of the screening device. Therefore, it is urgently needed to be improved. Utility Model Content

The connecting rod is fixedly connected to one end of the traction rope, and the fixed ring is sleeved on the discharge end of the second corrugated telescopic tube, and the side wall of the fixed ring is fixedly connected to the other end of the traction rope through a hanging ear. When in use, the low-speed motor slowly drives the traction rope at a speed of 3 to 10 r / min, so that the discharge end of the second corrugated telescopic tube swings back and forth at a low speed above the screen, so that the landing point of the material on the screen is constantly changing, thereby achieving the purpose of improving the screening efficiency.

[0007] Preferably, an exhaust pipe is provided on the top of the screening box, and one end of the exhaust pipe away from the screening box is connected to a dust collector. More preferably, the dust collector is a negative pressure belt dust collector.
