Description
Technical field
The utility model provides a kind of wear-resisting fuming furnace tuyere, 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 compound 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 melting slag, metal recovery rate is higher, and productivity is high, easy and simple to handle, available low grade coal 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, plumbous oxide and stannic 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 work-ing life, the company that change tuyere also affects fuming furnace blowing simultaneously often continues operation, adds production cost, reduces treatment capacity.
In addition, in the melt that the blowing of tuyere and shaft contact jaw is chewed and be immersed in for a long time up to 1250 DEG C, be very easily burnt, therefore blow and chew as loss parts, once scaling loss must be changed.It is be made up of front end cavity and transitional cavity that the blowing of current routine is chewed, and the inside cavity of adapter cavity is with bell-mouthed straight tube, this inner cavity is unfavorable for that coal dust flows, large to wall friction in cavity, fragile, and front cavity and transitional cavity realize being connected and fixing by flange, 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 running cost.
Therefore, be necessary to solve tuyere local problem easy to wear, realize extending its work-ing life, reduce and change number of times, and optimize the structure of tuyere easily worn part, save the cost of manufacture of tuyere.
Summary of the invention
Affect the problems such as the production of fuming furnace blowing for solving the easy loss in tuyere local, the utility model provides a kind of wear-resisting fuming furnace tuyere, to reduce making material and the manufacture difficulty of tuyere, thus reduces cost of manufacture.
The utility model is realized by following technical proposal: a kind of wear-resisting fuming furnace tuyere, 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 induction pipe 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: described transitional cavity is made up of the flanged (FLGD) outer tube in two ends and inner sleeve, the cavity that this 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.
Described front cavity comprises the straight tube of the convex dish of rear end band, middle part band axis hole, is sheathed on the outer and flange connected with the convex dish in rear end of straight tube, is connected by this flange and screw bolt and nut with transitional cavity.So that while being tightly connected with transitional cavity, facilitate the replacing of straight tube.
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: the utility model is related to cone cylinder by blowing the adapter cavity inner sleeve cavity chewed, and fine coal is more smooth in internal flow, reducing blowing the friction of chewing inwall, reaching abrasion resistant effect.Therefore, by optimizing the structure of the easily worn part of tuyere like this, and then solving tuyere local problem easy to wear, making to blow to chew and extend its work-ing life, reduce and change number of times.In addition, the straight tube of front cavity and flange are the design for disassembly of separate type, outer tube and the detachable design of inner sleeve also for being separated of transitional cavity, break tradition and blow the structure that the inner sleeve of chewing and flange be formed in one, therefore, when of the present utility model blow chew need change time, only need change inner housing section, outer tube can continue use.The utility model reduces the manufacture difficulty need changing parts (as the straight tube of front cavity and the inner sleeve of transitional cavity), has saved cost of manufacture, by original manufacturing cost 120 yuan/, reduces to 75 yuan/, and makes consuming time short, therefore reduce production suspension induced losses.Strengthen bore of delivering coal and can slow down the friction of swiftly flowing fine coal to tuyere inwall, extend the work-ing 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.
