Background
In the coal washing process flow, the transportation and transfer equipment (such as a belt conveyor and other incoming material equipment) is needed to be used for connecting the sorting equipment, a plurality of chute are used for transferring coal materials, raw coal can be classified into lump coal and foam coal, and the lump coal has large granularity and low water content and is not easy to be stuck on the chute; the foam coal has small granularity, more pores and high water content, and as the inner wall of the chute is made of metal and has large roughness, the foam coal is easy to be stuck and accumulated, thereby blocking the chute.
When raw coal is mixed into a chute for transfer before classification, large-granularity lump coal can impact and vibrate the chute, so that foam coal stuck on the chute is shaken off by vibration, accumulation is not easy to occur in the chute, and a blocking phenomenon is rarely caused; after the lump coal is classified by the classifying screen, when the lump coal singly enters the chute for transferring, the lump coal is lack of impact on the chute, and the water content of the lump coal is high, so that the lump coal is easy to adhere to the chute, and the chute is blocked along with the increase of the thickness of the adhesion, particularly when the water content of raw coal exceeds the standard or gangue is slurried, the lump coal chute is frequently blocked; after stopping, the machine is cleaned manually, and the production progress is affected.
In the existing solution, a blocking sensor and a vibration exciter are usually arranged on a chute, when blocking occurs, the blocking sensor is triggered to control the vibration exciter to work, so that accumulated materials at the blocking position are loosened to promote the materials in the chute to fall down, and the dredging effect is achieved. But when blanking volume is great, the material that blocks up in the chute is more, shakes and can not play good loose effect to because the granularity of foam coal is little, shake the progressively compaction that probably makes the piling up of granule foam coal, if on-the-spot unmanned carelessly, can lead to in the chute material to pile up too much and even spill over, increased the degree of difficulty of later stage manual cleaning.
