The invention discloses a coal jigging device. The coal jigging device comprises a power mechanism, a groove body, a movable screen, a coal discharging wheel, a lower cone body, a water flow horizontal circulation mechanism and a water flow vertical circulation mechanism. The water flow horizontal circulation mechanism comprises a rotating disc and multiple spiral grooves, a ring groove is formed in the inner wall of the groove body, the rotating disc is rotatably connected with the ring groove, multiple through frames are arranged on the rotating disc, blades are arranged in the through frames, a through hole matched with the exterior of the movable screen is formed in the center of the rotating disc, and the water flow vertical circulation mechanism comprises a cylinder and a plunger; the upper end of the plunger is fixed to the lower end of the movable screen, a cylindrical cavity is formed in the cylinder, the lower end of the plunger is connected into the cylindrical cavity, multiple transverse grooves are evenly formed in the cylinder, and are rotatably connected with a rotating plate, a check block is arranged on the outer wall of the cylinder, and an elastic part is arranged between the check block and the rotating plate. Compared with the prior art, the device has the beneficial effects that power generated during vertical reciprocated motion of the movable screen is used for generating horizontal and vertical circulation water flows in the water groove, coal jigging efficiency is greatly improved, and the jigging effect is good.
Description
technical field [0001] The invention belongs to the technical field of coal processing equipment, and specifically discloses a jigging coal preparation device. Background technique [0002] The jig machine is a gravity coal separation device, which can separate the coal mines by utilizing the different sedimentation velocities of the coal mines with different specific gravity in the vertical alternating water flow. The coal mines occupy different heights in the jig due to their different sedimentation speeds. The coal mines with a large specific gravity occupy the lower layer, and the minerals with a small specific gravity occupy the upper layer. They are discharged out of the jig through a special discharge device to realize the separation of light and heavy minerals. The moving screen jig mainly relies on external force to drive the screen to move up and down in the water medium, so that the coal is periodically loosened, and then stratified according to the density.
