Description
Technical field
The utility model provides a kind of the fuming furnace tuyere changing scaling loss part, belongs to fuming furnace blowing equipment technical field.
Background technology
Fuming furnace is the mixture blasting air and fine coal in liquid slag, makes the equipment that some valuable metal in slag evaporates with the form of metal, oxide or sulfide.Fuming furnace is former is the equipment processing lead blast furnace slag.1962, China, for the treatment of tin metallurgy slag, obtained the flue dust of stanniferous about 50%, makes the stanniferous amount of slag be down to less than 0.1% by 3%.In lead, zinc, tin smeltery, all materials containing volatile valuable metal and compound thereof, all can use fuming furnace process.Advantage that is plumbous with fuming furnace process, tin slag is: the heat that can utilize liquid slag, metal recovery rate is higher, and productivity ratio is high, easy and simple to handle, available colm or fuelled with natural gas.
The Main Function of fuming furnace tuyere compressed air and fine coal is blown in the slag in fuming furnace, produce heat and carbon monoxide after burning, make slag keep high temperature, and make the compound in slag, free ZnO steam, rise to the upper space of stove, run into CO
2or the air sucked in is oxidized to zinc oxide, lead oxide and tin oxide once again, and be collected with flue dust state, reach the object of blowing concentration of valuable metals.
Tuyere occupies very important status in whole fuming furnace blowing process.The fuming furnace of 4 squares, every day every, tuyere about will be jetted the fine coal of about 1.5 tons, and therefore tuyere concentrated wear is comparatively serious, affect tuyere service life, the company that change tuyere also affects fuming furnace blowing simultaneously often continues operation, adds production cost, reduces treating capacity.
In addition, tuyere and blowing of shaft contact jaw chew ante-chamber body running up in the melt of 1250 DEG C, are very easily burnt, therefore blow and chew as loss parts, once scaling loss must be changed.It is realized being connected and fixing by flange with transitional cavity by front cavity that the blowing of current routine is chewed, especially front cavity and flange are the structures be connected as a single entity, and therefore, must change during replacing together with intact flange, cost of manufacture certainly will be caused to increase, affect fuming furnace operating cost.
Therefore, be necessary to be improved prior art, optimize the structure of tuyere easily worn part, save the cost of manufacture of tuyere.
Summary of the invention
During for solving tuyere local easily wearing detail being changed, need integral replacing and increase the problem of fuming furnace operating cost, the utility model provides a kind of the fuming furnace tuyere changing scaling loss part, to reduce the cost of manufacture of tuyere.
The utility model is realized by following technical proposal: the fuming furnace tuyere of a kind of replacing scaling loss part, comprise in it cavity establishing hybrid chamber, cavity be provided with delivering coal of being communicated with hybrid chamber manage, blow chew, straight pipe, and be arranged on the snorkel be communicated with on straight pipe and with hybrid chamber, blow to chew and be made up of front cavity and transitional cavity, it is characterized in that: front cavity comprises the straight tube of the convex dish of rear end band, middle part band axis hole, be sheathed on the outer and flange connected with the convex dish in rear end of straight tube, be connected with transitional cavity by this flange and screw bolt and nut.So that while being tightly connected with transitional cavity, facilitate the replacing of straight tube.
Described transitional cavity is made up of the flanged (FLGD) outer tube in two ends and inner sleeve.
The cavity that described inner sleeve is formed is cone cylinder.This structure makes the flowing of fine coal more smooth, and to blowing, to chew interior wall friction less, reaches abrasion resistant effect.The processing of cone cylinder is also more convenient for making with bell-mouthed straight tube than routine, consuming time short.
Orchid managed by described cavity overcoat, and is connected with transitional cavity by this flange and screw bolt and nut.
Described cavity and transitional cavity connection arrange sealing ring.
The basal diameter of described cone cylinder is respectively 38mm and 100mm, and the height of cone cylinder is 140mm.
The internal diameter of described pipe of delivering coal is 100mm, and length is 300mm, compared to existing technology, strengthens bore of delivering coal and the flow velocity of fine coal can be made to decline, in order to slow down the friction of swiftly flowing fine coal to tuyere inwall.
The utility model has following effect and advantage: before the utility model, the straight tube of cavity and flange are the design for disassembly of separate type, break tradition and blow the structure that the inner sleeve of chewing and flange be formed in one, and the detachable design also for being separated of the outer tube of transitional cavity and inner sleeve, therefore, when of the present utility model blow chew need change time, only need to change straight-tube portion or inner housing section, flange and outer tube can continue to use.The cavity that inner sleeve is formed is cone cylinder, and fine coal is more smooth in internal flow, reduces blowing the friction of chewing inwall, reaches abrasion resistant effect.And the processing and fabricating need changing parts (as the straight tube of front cavity and the inner sleeve of transitional cavity) is simple, consuming time short, therefore reduce production suspension induced losses, also save cost of manufacture simultaneously, by original manufacturing cost 120 yuan/, reduce to 75 yuan/.Therefore, by optimizing the structure of the easily worn part of tuyere like this, and then solving the problem of high, the consuming time length of tuyere local replacing difficulty, considerably reducing the loss stopping production and change and cause.In addition, strengthen bore of delivering coal and can slow down the friction of swiftly flowing fine coal to tuyere inwall, extend the service life of tuyere, fuming furnace tuyere can be made to extend to 3 ~ 4 years by original 2 years by improvement of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of fuming furnace tuyere of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment 1
As Fig. 1, the fuming furnace tuyere only changing scaling loss part comprises in it cavity 10 establishing hybrid chamber 9, cavity 10 be provided be communicated with hybrid chamber 9 pipe 6 of delivering coal, blow chew, straight pipe 8, and be arranged on the snorkel 7 be communicated with on straight pipe 8 and with hybrid chamber 9, blow to chew and be made up of front cavity 1 and transitional cavity 3, wherein, front cavity 1 comprises the straight tube 16 of the convex dish 15 of rear end band, middle part band axis hole, be sheathed on the outer and flange 14 connected with the convex dish 15 in rear end of straight tube 16, be connected with transitional cavity 3 by this flange 14 and screw bolt and nut 2.So that while being tightly connected with transitional cavity 3, facilitate the replacing of straight tube 16.Described transitional cavity 3 is made up of the outer tube 5 at two ends flanged 13 and inner sleeve 4; The cavity that inner sleeve 4 is formed is cone cylinder, and the basal diameter of this cone cylinder is respectively 38mm and 100mm, and the height of cone cylinder is 140mm.The cavity of this conical column structure makes the flowing of fine coal more smooth, and to blowing, to chew interior wall friction less, reaches abrasion resistant effect.The processing of cone cylinder is also more convenient for making with bell-mouthed straight tube than routine, consuming time short.
