Description
Technical Field
The invention belongs to the technical field of belt descaling of a belt conveyor, and particularly relates to a belt descaling device and method for a return section of the belt conveyor.
Background
When carrying out coal operation under low temperature environment, the belt surface of conveyer can appear gluing the phenomenon of hardening to lead to the bend pulley of conveyer to constantly increase in radial dimension, and then lead to the pulling force that the belt bore also constantly to increase, will take place the belt tearing when the result is serious, cause production operation to be forced to stop.
In addition, if the thickness of the frozen adhesive plate on the surfaces of the belt and the bend pulley of the conveyor is uneven, uneven stress on the belt can be caused, and the belt can deviate when serious, so that normal production operation can be endangered.
Because the existence of the sticky hardening phenomenon not only affects the transportation safety of coal, but also affects the transportation efficiency of coal, the sticky hardening phenomenon also can reduce the bearing gross weight of the belt, and leads to the reduction of the transportation speed, and meanwhile, the maintenance cost is increased.
In order to reduce the effect of the caking phenomenon on coal transportation, some solutions have been proposed by the related technicians.
For example, chinese patent application No. 201511011433.8 discloses a belt circulation cleaning system, which is to set up a three-stage coal cleaner under the belt at the return section, remove the scale on the belt by the coal cleaner, and spray the surface of the belt by a sprayer, thereby completing the descaling of the belt. However, in order to ensure the transportation efficiency of coal, the belt must maintain a higher running speed, but the thickness of the frozen and adhered plate on the surface of the belt is uneven, and the belt cannot be thoroughly cleaned by means of the coal cleaner, because the belt can only be locally cleaned, the residual frozen and adhered plate on the surface of the belt still has adverse effects on the transportation of coal.
For another example, chinese patent application No. 2016056575. X discloses a pulverized coal conveyor belt cleaning device, this scheme sets up sprinkler bead and mud scraping roller through return stroke section belt below to carry out the belt scale removal through sprinkler bead and mud scraping roller cooperation. However, the hardness of the frozen and adhered plate structure on the surface of the belt is very high, the adhesive strength is also very high, the effect of reducing the hardness and the adhesive strength of the frozen and adhered plate structure is very limited only by simple water spraying, a large amount of residues still exist after the frozen and adhered plate structure is subjected to descaling effect of a mud scraping roller, the thoroughly of belt descaling cannot be met, and the residual frozen and adhered plate structure on the surface of the belt still has adverse effects on coal transportation.
