Description
Technical Field
The invention relates to the technical field of dust treatment in production workshops, in particular to a dust removal device for ore tank discharging.
Background
The mineral aggregates such as raw material ores, sintered ores and the like of the steel plant are often stored in a plurality of bins with the total length of tens of meters, and the mineral aggregates are transported to the tops of the bins through belts and are continuously and sequentially loaded into different bins through a movable discharging car. When mineral aggregate is loaded, a large amount of dust escapes due to factors such as large fall of the mineral aggregate, positive pressure in a bin, continuous operation and the like, and huge dust pollution is brought to a workshop.
The existing ore tank discharging dust treatment technology mainly comprises two main categories, namely a mode that a ventilation tank is matched with an external dust remover, and a mode that the dust remover moves synchronously along with a discharging car.
In the mode of ventilation groove cooperation external dust remover, external dust remover need be connected with the ventilation groove, and the main function of ventilation groove is the dust of carrying the dummy car discharge point suction, and current technical scheme has removal dust removal/ventilation car (ZL201821339696.0, ZL200720086152.3, ZL201811175865.6), partition formula ventilation groove (ZL201520040533.2) etc.. The ventilation groove that this kind of technical scheme adopted is down, left and right trilateral steel construction connection, and upper portion adopts the belt gland to realize sealing, and this kind of mode has certain ventilation suction capacity under the condition that the belt well pressed the cover left and right two sides, the dust that can the suction discharge point of certain degree produced. However, the length of the ventilating slot is generally tens of meters or even hundreds of meters, and along with the increase of the operation time, the belt is frequently opened and closed, so that the problems of belt deviation, aging, deformation and the like are easily caused, large-area air leakage at the upper part of the ventilating slot is directly caused, the air draft of the dust remover cannot be transmitted to a discharging point, and the dust catching effect cannot be formed. The reliability of the upper belt gland seal of the ventilation slot is a fatal weak point of the traditional ventilation slot.
The mode that the dust remover follows dummy car simultaneous movement is at the other configuration dust remover of dummy car, and the dust of unloading point suction directly gets into the dust remover and purifies, and this mode dust remover and dummy car synchronous operation do not have the ventilation groove that removes, the drawback of the air leakage of the ventilation groove of avoiding to a certain extent, and prior art scheme has totally enclosed removal ventilation dust pelletizing system (ZL201410303004.7), parallel movement's sack cleaner (ZL201310127255.X), load pulse dust collector (ZL200620076303.2, ZL200720042556.2) on the removal flatbed. However, the dust remover of the technical scheme needs to run synchronously with the discharging car, and the dust remover is also positioned indoors, so that the volume of the dust remover is greatly limited, the upper limit of the treatment capacity design of the dust remover is reduced under the requirement of reducing the volume of the dust remover, the air draft of a discharging point is obviously insufficient, the dust removing effect is poor, meanwhile, the dust remover is positioned indoors, the difficulty of the dust removal, bag replacement and other maintenance work is increased, and the dust removing effect is influenced. In addition, when the dust remover moves along with the dummy car, the cable that needs the power supply moves along with, and the high-power cable is removed back and forth in tens meters even more distance of passing hectometer and will reduce the reliability of cable, increases the power failure rate, has the danger of electric leakage simultaneously. Finally, the whole weight of the dust remover is large, the dust remover moves back and forth along with the discharging car, power needs to be additionally configured, besides increasing the energy consumption of the system, the dust remover is independently configured with power and the discharging car is independently configured with power, the difficulty of synchronous movement of the dust remover and the discharging car is increased, and meanwhile, the fault rate of the whole system is increased.
