Abstract
The utility model discloses an oxygen lance water cooling device for a bottom blowing lead smelting furnace. The oxygen lance water cooling device comprises two semi-cylindrical water jackets with a hollow structure consisting of bottom plates, arc-shaped webs, vertical plates and top plates. The diameter of the water jacket is greater than that of the top plate. The centers of the vertical plates of the two semi-cylindrical water jackets are sunk towards cavities of the water jackets to form arc-shaped gaps. After two water jackets are in butt joint to form a cylinder, two arc-shaped gaps form a whole circular oxygen lance hole for the oxygen lance passing through. The top plate of each water jacket is provided with a water inlet tube and a water outlet tube communicated with the cavity of the water jacket. The oxygen lance water cooling device provided by the utility model is simple in structure and novel in concept, softened water is adopted as a cooling medium, and the oxygen lance is protected by reducing temperatures of the oxygen lance and the fireproofing material around the oxygen lance so as to improve the service life of the oxygen lance.
Description
Technical field
The utility model belongs to plumbous bottom-blown smelting apparatus field, relates in particular to a kind of water cooling plant of bottom blowing lead-smelting furnace oxygen rifle.
Background technology
At present, China generally adopts Shuiko mountain method of smelt lead and Henan light lead smelting process to refine lead, and the material that refines in the plumbous process all needs through oxidation, two smelting processes of reduction, and wherein oxidising process is in the bottom blowing lead-smelting furnace, to accomplish.Bottom blowing lead-smelting furnace body of heater is a tubular structure, and the top is provided with charging opening and smoke outlet, and body of heater two ends end socket is provided with siphon lead taphole, slag notch and burner, and bottom of furnace body is provided with the oxygen rifle.Material is added by the top feeding mouth; Oxygen is blown into by bottom oxygen rifle high pressure; Complicated reaction takes place and obtains lead bullion and high lead slag in material and oxygen in high-temperature fusant, thereby because the different realizations with high lead slag density of lead bullion separate up and down, the high lead slag at top is discharged by slag notch; The lead bullion of bottom is discharged by siphon lead taphole, must guarantee enough pressure and the blowing oxygen quantities of oxygen in the whole process.The oxygen rifle that said bottom of furnace body is provided with inserts body of heater by bottom oxygen rifle base, and the intravital envrionment temperature of stove is up to 1000 ℃, and operating mode is very abominable, causes the work-ing life of oxygen rifle shorter, often changes, and has had a strong impact on to produce to carry out smoothly.
Current, each plumbous smeltery's bottom blowing lead-smelting furnace oxygen rifle turnover rate is higher, does not also find effective way to solve this difficult problem so far.
Summary of the invention
For addressing the above problem; The purpose of the utility model provides a kind of bottom blowing lead-smelting furnace oxygen gun water-cooling device; It is heat-eliminating medium that this device adopts softening water, thereby relies on the temperature that reduces oxygen rifle and oxygen rifle refractory materials on every side to reach the purpose of protecting the oxygen rifle, thereby improves the work-ing life of oxygen rifle.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of bottom blowing lead-smelting furnace oxygen gun water-cooling device; Comprise two half bar shape water jackets of forming by base plate, arc-shaped webs, riser and top board respectively with cavity structure; And the diameter of water jacket base plate is greater than the diameter of top board; The riser center of described two and half bar shape water jackets has been recessed to form arc notch to the inner chamber of water jacket, and two water jackets are used for the full circle oxygen rifle hole that the oxygen rifle passes to being connected into latter two of arc notch composition of complete circle cylinder; Be provided with the water inlet pipe and the rising pipe that are communicated with the water jacket inner chamber on the top board of said two water jackets.
Described bottom blowing lead-smelting furnace oxygen gun water-cooling device is provided with some dividing plates in the inner chamber of its water jacket.
Described bottom blowing lead-smelting furnace oxygen gun water-cooling device, the edge of its base plate along the circumferential direction is evenly equipped with gusset, and a side of gusset is connected with the outer side wall of web.
Owing to adopt technique scheme, the utlity model has following meliority:
1, this apparatus structure is simple, and is novel, and the employing softening water is a heat-eliminating medium, relies on the temperature that reduces oxygen rifle and oxygen rifle refractory materials on every side to reach the purpose of protecting the oxygen rifle, thereby improves the work-ing life of oxygen rifle.
2, because two semicircle jacket water systems are separate,, can't influence the work of another one water jacket, further guarantee continual provide protection the oxygen rifle if fault has appearred in one of them of water jacket, simultaneously also easy to replace and maintain.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
A kind of bottom blowing lead-smelting furnace oxygen gun water-cooling device; Comprise two half bar shape water jackets of forming by base plate 4, arc-shaped webs 1, riser 6 and top board 3 respectively with cavity structure; And the diameter of water jacket base plate 4 is greater than the diameter of top board 3; Riser 6 centers of described two and half bar shape water jackets have been recessed to form arc notch to the inner chamber of water jacket, and two water jackets are used for the full circle oxygen rifle hole 7 that the oxygen rifle passes to being connected into latter two of arc notch composition of complete circle cylinder; Be provided with the water inlet pipe 2 and rising pipe 9 that are communicated with the water jacket inner chamber on the top board 3 of said two water jackets; Be provided with some dividing plates 5 in the inner chamber of said water jacket, play the effect of the above and below of supporting water jacket, and the water coolant that gets into the water jacket inner chamber from water inlet pipe is played guide functions.The edge of said base plate 4 along the circumferential direction is evenly equipped with gusset 8, and a side of said gusset 8 is connected with the outer side wall of web, and the one-piece construction of water jacket is played booster action.
During installation, two and half bar shape water jackets are fixed together through the oxygen rifle base of bolt and bottom blowing lead-smelting furnace respectively; During work; The oxygen rifle is inserted body of heater inside from the oxygen muzzle blows; The oxygen rifle in the course of the work, the water inlet pipe from two water jackets feeds water coolant respectively to the inner chamber of water jacket, the guide effect lower edge curve of the dividing plate of water coolant in the water jacket inner chamber; Thereby realize the quick heat exchange between water coolant and water jacket, play the effect of protection oxygen rifle and oxygen rifle refractory materials on every side; In addition,,, can't influence the work of another one water jacket, further guarantee continual provide protection the oxygen rifle if fault or damage have appearred in one of them of water jacket because two semicircle jacket water systems are separate.
