Description

TECHNICAL FIELD

[0001] The utility model relates to a medium screen technical field, concretely relates to a medium screen's feeding assembly and medium screen. BACKGROUND

[0002] The medium screen is mainly used for medium removal, dehydration and desliming, and can efficiently treat fine coal dehydration, desliming and medium removal in the washing process of the coal industry. The medium screen is driven to vibrate by a vibrating mechanism, so that the material forms a particle accumulation layer on the screen surface. The larger particle material stays above the screen surface to form a slurry layer, and the smaller particle material enters the screen bottom through the screen hole. The filter medium (such as a fine screen or a filter cloth) placed on the screen surface allows the water to be discharged through the screen hole, realizing solid-liquid separation.

[0003] The screen surface of the medium screen can be an arc-shaped screen plate surface. In use, the vibrating mechanism drives the arc-shaped screen plate surface to vibrate, and the material is uniformly fed into the screen surface and moves under the action of centrifugal force and gravity. Due to the arc shape of the screen surface, the material forms continuous jumping and tumbling motion on the screen surface, and different particle sizes of the material gradually separate due to the difference in motion trajectory. Large particle materials move slowly forward on the screen surface due to inertia, and finally stay on the screen surface or are discharged; and small particle materials are more likely to fall into the collecting device below through the screen hole, thereby realizing the classification and separation of the material. However, in actual application, the incoming material enters the arc-shaped screen plate surface at different speeds due to the influence of pipeline pressure, and the material with too fast speed will rush out of the arc-shaped screen plate surface, resulting in ineffective use of the screen surface.
