The invention discloses an energy-saving
coal screening device. The energy-saving
coal screening device comprises an outer shell, and a feed inlet is integrally formed in one end of the upper surfaceof the outer shell. A
discharge hole is integrally formed in the side, different from the feed inlet, of the outer shell, and a
slag discharge opening is integrally formed in the position, located below the
discharge hole, on one side of the outer shell. A screen cloth is fixed to the middle position in the outer shell by bolts, and a
conveyor belt is arranged on one side of the outer shell. The feed inlet and the
conveyor belt are fixedly connected by a connecting
assembly, and the connecting
assembly comprises a connecting plate, a rotating rod, threaded holes, limiting bolts and baffles, wherein one side of the feed inlet is rotatably connected with the connecting plate through the rotating rod. According to the energy-saving
coal screening device, the connecting plate is arranged at the feed inlet, the connecting plate is rotatably connected to one end of the feed inlet by the rotating rod, and one end of the connecting plate is connected to the
conveyor belt through the limiting bolts, so that the conveyor belt is able to accurately transport coal to the feed inlet when transporting the coal, the number of times of debugging is reduced, and work efficiency is indirectly improved.
