Abstract
The utility model discloses a lifting device capable of preheating charging. The lifting device capable of preheating the charging comprises a lifting channel, a bucket elevator is arranged in the lifting channel, a ringlike chain is wound between an upper transmission drum and a lower transmission drum of the bucket elevator, a plurality of delivery hoppers are evenly distributed on the ringlike chain, the upper portion of the lifting channel is communicated with a furnace feed channel, the bottom of the lifting channel is communicated with a charging feed channel, a charging conveying mechanism installed at a position corresponding to the position of a feed inlet in the charging feed channel is linked with the bucket elevator, a heat-resisting insulation fibre layer is arranged on an inner wall of the lifting channel, a dust remover and an induced draft fan are sequentially arranged at the charging feed channel where an outer side of the feed inlet is located, and air vents are arranged on arc-shaped boards of the delivery hoppers. The lifting device capable of preheating the charging has the advantages of being simple in structure and capable of fully utilizing hot gas in a furnace to heat the charging; the charging can be heated to at least around 300 DEG C during a lifting process, and energy consumption of the furnace can be reduced by 10-15 percent.
Description
Technical field
The utility model relates to lifting device, but especially relates to lifting devices a kind of and the matching used preheating furnace charges of multiple kiln such as preheating furnace, furnace cupola, limekiln, calcining kiln.
Background technology
Make steel with kilns such as furnace cupola, limekiln, calcining kiln, preheating furnaces when adding furnace charge; Need to use lifting device that the furnace charge that transports is mentioned the back and add in the body of heater, generally use bucket elevator that cold stock is delivered in the feeding-passage of kiln from outside feeding-passage from fire door.Because the exhaust emissions amount of kiln is very big and temperature very high (generally can reach 600-1000 ℃), these tail gas directly enter atmosphere, have not only wasted the energy, have also polluted atmospheric environment.
Summary of the invention
But the purpose of the utility model be to provide a kind of in lifting process the lifting device of preheating furnace charge.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
But the lifting device of the described preheating furnace charge of the utility model comprises the lifting passage that is arranged on body of heater one side, in promoting passage, is provided with bucket elevator, is looped around on the ring chain between driving drum up and down of bucket elevator and is evenly equipped with a plurality of conveyor hoppers; The top of said lifting passage is connected with the kiln feeding-passage, and the bottom of said lifting passage is connected with the furnace charge feeding-passage; Be connected mutually with said bucket elevator with the furnace charge conveying mechanism that is provided with in the corresponding furnace charge feeding-passage in charging aperture position; The inwall of said lifting passage is provided with heat-resisting insulation fibre layer, is positioned on the furnace charge feeding-passage in the charging aperture outside to be disposed with deduster and air-introduced machine.
Offer passage on the arc face of said conveyor hopper.
The aperture of said passage is 5-6mm.
The said driving drum place of going up is provided with cooling device.
The advantage of the utility model is simple in structure, can make full use of the hot gas heating furnace charge of kiln discharging, and in the charge hoisting process, cold stock can be heated at least and get into about 300 ℃ in the body of heater again, can make the kiln energy consumption reduce 10-15%.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the profile of conveyor hopper among Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2; But the lifting device of the described preheating furnace charge of the utility model; Comprise the lifting passage 2 that is arranged on body of heater 1 one sides; In promoting passage 2, be provided with bucket elevator, be looped around on the metal ring chain 5 of 4 on last driving drum 3 and underdrive cylinder of bucket elevator and be evenly equipped with a plurality of conveyor hoppers 6; The top that promotes passage 2 is connected with kiln feeding-passage 7, and the bottom that promotes passage 2 is connected with furnace charge feeding-passage 8; Be connected mutually with bucket elevator with the furnace charge conveying mechanism 10 that is provided with in the corresponding furnace charge feeding-passage 8 in charging aperture 9 positions; The inwall that promotes passage 2 is provided with heat-resisting insulation fibre layer 11 (can use asbestos or rock wool material); Be positioned at and be disposed with deduster 12 and air-introduced machine 13 on the furnace charge feeding-passage in charging aperture 9 outsides; For improving hot blast exchange effect, on the arc face of conveyor hopper 6, offering the aperture is the passage 14 of 5-6mm; Because the temperature that promotes in the passage 2 is very high; For prolonging the service life of driving drum inner bearing, 3 places are provided with cooling device at last driving drum, generally can use circulation that it is cooled off, lowers the temperature; Neither waste water resource can also play good cooling effect.
During work; Under the effect of air-introduced machine 13, the high temperature hot gas (being higher than 600 ℃) in the kiln 1 gets into through kiln feeding-passage 7 and promotes passages 2, offers furnace charge in the conveyor hopper 6 of passage 14 in lifting process; Produce convection current with high temperature hot gas; With charge preheating, the charge-temperature that gets in the kiln is reached about 300 ℃, can make the kiln energy consumption practice thrift 10-15%.
The utility model utilizes the hot gas preheating furnace charge of kiln discharging, has reduced the kiln energy consumption, has practiced thrift the energy.Because the effect of air-introduced machine 13; High temperature hot gas in the kiln can be passed through kiln feeding-passage 7, promote passage 2 and 8 discharges of furnace charge feeding-passage; And furnace charge can be raised the hot gas heating in the passage 2 in lifting process; For increasing heat insulation effect, the inwall that promotes passage 2 is provided with heat-resisting insulation fibre layer 11; Because the particle diameter of furnace charge is generally 7-8mm, be that the passage 14 of 5-6mm both can improve the heat exchange effect so be opened in aperture on the conveyor hopper 6 arc faces, can guarantee the lifting capacity of furnace charge again.
