Background
The granularity of the coal dust transported into a primary stock ground of a metallurgical enterprise is 0-100mm, the water content is about 12%, water spray dust fall treatment is needed in the automatic coal unloading process of a tipper, and water is taken into the coal dust again, so that the water-containing coal dust is partially adhered to the inner side of a train wagon after unloading, and particularly, the train wagon is seriously adhered due to low temperature in winter in the north, and the train wagon needs to be cleaned. At present, most enterprises rearrange empty vehicles, send the bonding materials in the manual sweeper into an underground material returning transfer station through a belt conveyor, and then send the bonding materials into the underground material returning transfer station for recycling.
The receiving bin, the transportation system and the underground return material transfer station which are matched with the tipper for unloading coal are all positioned below the railway transportation line, the design and construction of an underground deep foundation pit are needed, the design difficulty is high, the construction cost is high, the construction period is long, the difficulty is high, and underground equipment is inconvenient to maintain in use.
The invention discloses a method for recovering residual coal dust, aiming at the problems of complex material return flow of residual coal dust in a vehicle skin, high design difficulty of an underground deep foundation pit, high construction cost, long construction period, high difficulty and inconvenient maintenance of underground equipment.
Disclosure of Invention
The invention aims to solve the problems and provides a method for recovering residual coal dust in the skin of a rollover locomotive.
The invention discloses a method for recovering residual coal dust, aiming at the problems of complex material return flow of residual coal dust in a vehicle skin, high design difficulty of an underground deep foundation pit, high construction cost, long construction period, high difficulty and inconvenient maintenance of underground equipment.
The purpose of the invention is realized as follows: a method for recovering residual coal dust in the skin of a rollover locomotive comprises the following steps: the method comprises the following steps: lifting the elevation of the No. 1 cleaning belt conveyor to a depth of-1.2 to-1.5 m underground, simultaneously shortening the length of the belt conveyor to 90 to 92m, and then manually pushing the residual materials in the vehicle into the No. 1 cleaning belt conveyor; step two: lifting the elevation of the No. 2 cleaning belt conveyor to a depth of-4 m to-3.9 m underground, simultaneously shortening the length of the belt conveyor to 5m to 5.2m, and then conveying the residual materials from the No. 1 cleaning belt conveyor to the No. 2 cleaning belt conveyor; step three: the chute connected below the No. 2 cleaning belt conveyor conveys the residual materials to a tipper bin to complete the cleaning operation.
Furthermore, the method recovers the residual materials in the empty vehicle.
The invention has the beneficial effects that: 1) according to the invention, through simplifying the return material transportation link, an underground return material transfer station is cancelled, the cleaning belt conveyor is shortened, the height position of the belt conveyor is lifted, the project design and construction cost is greatly reduced, and the maintenance amount and cost of the belt conveyor equipment are reduced. According to the traditional process design, the cost of deep foundation pit support, construction measures and the like is about 4100 ten thousand yuan, the cost is adjusted to 3200 ten thousand yuan through the optimized arrangement scheme, and the project investment is reduced by nearly 900 ten thousand yuan; the long-term maintenance workload is reduced by nearly 70%, and the production efficiency is improved, and meanwhile, the method has extremely high economic benefit.
2) The invention adopts the mode of directly returning the returned coal powder to the coal bunker of the tipper for the first time, simplifies the process, reduces the material transportation distance, greatly saves the investment and greatly shortens the construction period by about 2 months.
Drawings
The invention is further described below with reference to the accompanying drawings.
FIG. 1 is a process flow diagram of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
Wherein: 1.1# clear car belt feeder, 2.1# clear car belt feeder.
Detailed Description
The invention changes the returned material transportation into the reverse direction by rearranging the returned material flow, fully utilizing the space between the empty wagon line and the wagon tipper, canceling an underground returned material transfer station of-12.0 m, canceling an underground-10.0 m and a 2# cleaning belt conveyor with the length of 23m, deeply lifting the underground-6.0 m and 1# cleaning belt conveyor, adopting the underground 1# cleaning belt conveyor with the depth of only-1.2 to-1.5 m, feeding the underground 1# cleaning belt conveyor with the length of only 5m and the depth of-4.0 m into the 2# cleaning belt conveyor with the length of only-4.0 m, and then directly feeding the underground 1# cleaning belt conveyor into a loading port of an underground bin of the wagon tipper of-4.0 m through a chute without entering a ground pit of the underground wagon tipper of-15.0 m through transportation.
A method for recovering residual coal dust in the skin of a rollover locomotive comprises the following steps:
the method comprises the following steps: and (3) lifting the elevation of the No. 1 cleaning belt conveyor from-6.0 m underground to-1.2 to-1.5 m underground, simultaneously shortening the length from 120m to 90m, and then manually pushing the residual materials in the vehicle into the No. 1 cleaning belt conveyor.
Step two: and (3) canceling an underground returning material transfer station with the elevation of-12 m, lifting the elevation of the No. 2 cleaning belt conveyor from the underground of-10.0 m to the underground depth of-4, simultaneously shortening the length from 30.5m to 5m, and then conveying the residual materials to the No. 2 cleaning belt conveyor from the No. 1 cleaning belt conveyor.
Step three: and the chute connected below the No. 2 cleaning belt conveyor conveys the residual materials to a hopper of the tipper to finish cleaning operation.
The method for recovering the residual coal dust in the skin of the dumper is successfully applied to the intelligent upgrading and transforming project of the logistics before the stainless steel and the stainless iron, the project investment is greatly saved, the existing facility runs stably and reliably, and the method is praised by users.
