Description
Technical field
The utility model belongs to cleaning apparatus, is specifically related to a kind of Argon station cleaning apparatus, is applicable to the dedusting at Argon station in more than 200t mammoth conveter system.
Background technology
Converter-Argon station technique is the degassed secondary refining method with removing non-metallic inclusion of a kind of easy molten steel, it is advantageous that technique is simple, and equipment is cheap, and refining effect is remarkable. Ladle bottom Argon when the process of realization is converter tapping, complete ladle running of tapping processes station and adds slag material to Argon station, and adds iron alloy and wire feeding process by steel grades requirement, and ladle is omnidistance argon bottom-blowing at Argon station. But, owing to stirring molten steel at Argon station ladle bottom blowing argon gas, moreover add slag material, iron alloy and wire feeding process to molten steel surface, the reaction of molten steel internal chemical is violent, produces a large amount of flue dust, so place is one of key area of BOF steelmaking shop final dusting.
As depicted in figs. 1 and 2, traditional dust removal installation at Argon station is arrange the dedusting petticoat pipe 3 connecting cleaning shaft 1 between ladle 4 top and Argon station platform 2, the position of dedusting petticoat pipe 3 and detailed dimensions are determined by the size of ladle 4, the diameter that the diameter of usual dedusting petticoat pipe 3 is greater than ladle 4 is about 1m, along distance dedusting petticoat pipe 3 times edge about 0.4m��0.6m on ladle 4.
If establishing little tonnage converter system ladle diameter (d) and height (h), molten steel volume and the ladle diameter of its carrying, relation highly are approximately: V1=�� h(d/2)2, the exhausting area of traditional way dust excluding hood is S1=�� [(d+1)/2]2; Along with ladle tonnage increases, its diameter increment is d, and height increment is h, its volume V2=�� (h+ h) (d+ d/2)2, dilatation V=V2-V1; In little tonnage converter system, the exhausting area of traditional way dust excluding hood is S2=�� [(d+ d+1)/2]2, dust excluding hood exhausting area increase is S=S2-S1. By above analysis, along with the increase of ladle tonnage, the increment V of its carrying molten steel volume is not directly proportional to dust excluding hood exhausting area increase S, and the rate of rise of molten steel volume is greater than the speed of dust excluding hood exhausting area. Therefore, in actual production, using tradition Argon station cleaning apparatus in more than 200t converter system, its dust removing effects is often not good.

Embodiment
Embodiment 1:
Poor for the dust removing effects at Argon station in mammoth conveter system in order to overcome tradition Argon station cleaning apparatus, inefficient problem, present embodiments provide a kind of Argon station cleaning apparatus as shown in Figure 3 and Figure 4, comprise cleaning shaft 1, the platform column 5 of Argon station platform 2 and support Argon station platform 2, below described Argon station platform 2, surrounding is provided with gear cigarette wall 6 and Smoke prevention baffle plate 7, Argon station platform 2, the semi open model that gear cigarette wall 6 and Smoke prevention baffle plate 7 form Argon station platform 2 bottom surface opened all round closure stores cigarette space, described Argon station platform 2 is provided with multiple dedusting air port 8, this dedusting air port 8 is connected with cleaning shaft 1, described cleaning shaft 1 is provided with cleaning shaft valve 9.
Wherein, centered by ladle 4, the platform column 5 of both sides respectively has two, gear cigarette wall 6 is built by laying bricks or stones between the platform column 5 of two, every side, the semi open model that Argon station platform 2, gear cigarette wall 6 and Smoke prevention baffle plate 7 are formed stores the bottom surface that cigarette is spatially located at Argon station platform 2, and in order to not affect the current of ladle 4 under stove, the height H arranging Smoke prevention baffle plate 7 is 1.5m��2m.
During work, first ladle car is travelled to Argon station station, open the cleaning shaft valve 9 on cleaning shaft 1. Bottom the ladle 4 at Argon station, blowing argon gas stirs molten steel, moreover add slag material, iron alloy and wire feeding process to molten steel surface, the reaction of molten steel internal chemical is violent, the a large amount of flue gas residence produced store in cigarette space in the semi open model being made up of Smoke prevention baffle plate 7, Argon station platform 2 and gear cigarette wall 6, flue gas is taken away continually by the dedusting air port 8 on Argon station platform 2, treat that ladle 4 is complete in the process of Argon station station, close cleaning shaft valve 8, wait next heat of molten steel pending.
As one preferred embodiment, described dedusting air port 8 has four, and the position in dedusting air port 8 is determined, the middle part being generally distributed between ladle 4 medullary ray and platform 2 edge, Argon station according to Argon platform 2 processing set-up.
In addition, store the flue dust in cigarette space to effectively extract above-mentioned semi open model, it is to increase air suction efficiency, Argon station platform less than 2 is inserted in above-mentioned dedusting air port 8. If dedusting air port 8 is arranged on the surface of Argon station platform 2, owing to on-the-spot environment is severe, Argon station platform 2 has slight jitter for a long time, then cause the sealing poor effect of dedusting air port 8 with platform 2 place, Argon station, affect air suction efficiency.
And Argon station platform 2 bottom surface is provided with some structural beams, the degree of depth below Argon station platform 2 is inserted in dedusting air port 8 needs the height exceeding structural beams, otherwise exhausting poor effect, flue dust is easily formed in " dead band ", and it is 0.5��1m that the degree of depth below Argon station platform 2 is inserted in general dedusting air port 8.
This kind of Argon station cleaning apparatus that the utility model provides stores cigarette space and significantly reduces by arranging semi open model and escape flue dust, for plant operations personnel create good Working environment, improve Air quality in workshop, simultaneously, improve Argon station efficiency of dust collection, reduce dedusting fan load, it is achieved the requirement of energy-conserving and environment-protective.
More than enumerating is only to illustration of the present utility model, does not form the restriction to protection domain of the present utility model, and every design same or similar with the utility model all belongs within protection domain of the present utility model.
