Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage definitely clear, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
Referring to Fig. 1, a kind of side-blowing bath smelting furnace of the utility model visits slag sampler, including hoist engine 1, extension iron staff
2, it is connected iron staff 5 and bottom concave ring 8.Wherein, the interstitial hole 7 and bottom lock 6 that bottom concave ring 8 is arranged by center are fixed on rank
Meet the lower end of iron staff 5, total height 2m.Extend iron staff 2 to link by the connection ring of upper end with guy wire one end, guy wire bypasses
The top pulleys of top are connect with hoist engine 1, can be guaranteed to visit the uniform descent of slag sampler in use process, be risen.Linking
The upper end of iron staff 5 is equipped with external screw joint 4, extends 2 lower end of iron staff and is equipped with internal thread interface 3, external screw joint 4 connects with internal screw thread
Mouth 3 matches, and is flexibly connected linking iron staff 5 with iron staff 2 is extended.Lower end is connect with linking 5 upper end of iron staff.It is connected 5 He of iron staff
The diameter for extending iron staff 2 is 4cm, and total length is 4 ~ 7m.The upper surface of bottom concave ring 8 is equipped with annular groove around interstitial hole 7
9, lower surface is arcwall face.The outer diameter of bottom concave ring 8 is 10cm, and bottom concave ring 8 is poured using steel mold；Bottom concave ring
Edge thickness between 9 outer diameter of 8 outer diameters and annular groove is 2.5 ~ 3.5cm.It is connected iron staff 5, extends iron staff 2 and bottom concave ring 8
Material be anti-be 1100 ~ 1300 DEG C by temperature high temperature resistant cast iron.
In actual use, hoist engine 1, extension iron staff 2, linking iron staff 5, bottom concave ring 8 are subjected to installation connection.
It visits slag sampling and needs to obtain the slag specimen product of upper surface in furnace and the sample of corresponding concave ring arrival layer, and pass through sampler and hang
Slag height h2, hoist engine transfer height h1, determine the height of counter sample layer.Slag device bottom will be visited in operating process close to side-blown
Smelting furnace visits cinder notch, remembers that side-blown stove visits cinder notch apart from furnace bottom height h0(equipment known quantity), regulation hoist engine is transferred
It visits inside slag device to molten bath material, note hoist engine transfers height h1, and further operating hoist engine, which rises, visits slag device, remembers iron surface
Dross point distance visits slag device bottom dross height h2.By the above h0 known parameters, h1, h2 detecting parameter, it is known that side-blown smelting furnace
Upper layer slag specimen corresponds to liquid level H1=h0-h1+h2 in furnace in furnace, visits slag device bottomside sounding point liquid level H2=h0-h1.Into one
Step waits after visiting the cooling of slag device, takes linking iron staff surface dross sample upper layer slag specimen Z1, bottom concave ring bottommost sample concave ring bottom
Portion slag specimen Z2.By above-mentioned it was verified that a kind of side-blowing bath smelting furnace, which in actual use, changes tradition, visits slag stick
The shortcomings that surface sample can only be taken, realizes primary sample and obtains the slag specimen product of two levels of bath, and can calculate pair
Answer the liquid level of slag specimen layer.Therefore, the control that height h1 can be transferred by hoist engine, detects inside side-blowing bath smelting furnace
The sample of different liquid level layers, by further testing and analyzing, the operating condition of depth understood in furnace is production technology
Regulation provides more accurate guidance, guarantees the stable operation of production.
