Embodiment 1

[0066] In this embodiment, if figure 2 As shown, above the high tuyere platform 8 is provided with a blast furnace mud operation door 2 between the blast furnace frame column 30 and the high tuyere platform column 31, the high tuyere platform is provided with an additional iron ditch above the tuyere operation door 3, and the low position The casthouse platform is provided with a low-level casthouse platform column 33 and its transverse wind retaining wall 16, and the top suction and dust removal device on the elevated opening machine 52 side. Double doors, the structure of the double doors is as follows:

[0067] Including door frame, door handle, side-by-side double doors, door latches and door hinges, wherein: side-by-side double doors are symmetrically fixed on both sides of the door frame with one left and one right; The high position tuyere platform 8 is a steel structure platform covered with refractory bricks. The low casthouse platform 9 is a reinforced concrete st...

Embodiment 2

[0074] The scheme of this embodiment is as follows: the whole device also includes a high-position tuyere platform above which is provided with a tuyere operation door 3 above the iron ditch, and the tuyere operation door 3 is a double-track three-leaf rectangular door; the tuyere operation door 2 includes a door frame, a door handle, an upper The suspension mechanism, the lower pulley and the upper convex track; the two pulleys are fixedly connected through the wheel shaft to form an integrated tuyere operation door; the upper convex track is fixed on the bottom beam above the high-level tuyere platform.

[0075]When the tuyere of the blast furnace is blocked near the operation door 3 of the tuyere, safety measures should be strictly followed. First, wear protective masks, earplugs and other labor protection supplies, and use a gas alarm to measure the gas in the area around the tuyere to meet the allowable gas concentration. After the conditions are met, use the door handle t...

Embodiment 3

[0078] Its basic structure is the same as that of Embodiment 1, and the improvement is that: redesign the air suction port 7 on the top of the flat cover, and under the condition that the large-area three-section pipe cover ring beam 14 remains unchanged, it can be lifted for the mud gun machine and its support. Reserve the movable cover plate 36 on the top of the mud gun machine and its supporting maintenance channel, and split the air suction port 7 on the top of the flat cover and the upper three-section dust collection cover 1 into three sections; that is, the mud gun machine and its supporting maintenance channel end section There are three parts: pipe cover 11, mud gun machine and its support and maintenance channel front section pipe cover 12 and mud gun machine and its support and maintenance channel pipe cover 13. The mud gun machine and its support and maintenance channel pipe cover 13 are detachable. All are supplemented with external ribs to meet the rigidity of the...

Abstract

The invention discloses a blast furnace taphole top suction dust removal device, and belongs to the field of blast furnace dust removal system equipment. The blast furnace taphole top suction dust removal device aims at the problems that in the existing technology that a blast furnace is provided with a horizontal tapping machine, a dust removal device is weak in trapping capacity during high-position operating, the escape phenomenon is serious due to the influence of cross wind, and the operating environment of a casting house is poor. According to the scheme, the blast furnace taphole top suction dust removal device is adopted and comprises a high-position tuyere platform and a low-position casting house platform. The high-position tuyere platform is arranged above the low-position casting house platform and supported through high-position tuyere platform stand columns and a blast furnace frame column. The low-position casting house platform is supported through a low-position casting house platform stand column and the blast furnace frame column. A ring beam is arranged on the upper portion of the blast furnace frame column. A duct collection cover is arranged above the high-position tuyere platform, the low-position casting house platform and the ring beam in a covering manner. The blast furnace taphole top suction dust removal device can achieve the effects of being simple in structure, low in the manufacturing cost , safe and reliable, easy to operate and minimum in influence on normal iron making production and equipment maintenance, maintenance is convenient,, and the post environment is good.

Description

technical field [0001] The invention relates to the field of blast furnace dust removal system equipment, in particular to a blast furnace taphole top suction dust removal device. Background technique [0002] The top suction dedusting device of the blast furnace casthouse belongs to a device of the dust removal system of the casthouse, which can be used to seal the taphole at the opening of the horizontal opening machine, cushion sand and mud gun machine mud through the top suction dedusting device of the blast furnace casthouse. A blast furnace casthouse top suction dedusting device for instantaneous flue gas capture has been widely used in metallurgy, casting and other industries. [0003] For a blast furnace equipped with a horizontal opening machine, the top suction and dust removal device of the casthouse is flush with the tuyere platform of the blast furnace through the top of the hood, that is, the dust removal of the taphole adopts the method of strong smoke exhaust...
