Abstract
The utility model provides a pressurizing bypass device. The pressurizing bypass device comprises a pressurizing pipe and a pressurizing valve arranged on the pressurizing pipe, and is characterized in that pressurizing pipelines positioned at the front and back ends of the pressurizing valve are provided with branch pipes; each branch pipe is provided with a bypass valve. When the pressurizing valve is in failure and cannot be opened for air supply, the bypass valves can be conveniently opened to supply air by the branch pipes, so that high temperature hot air in a hot air furnace is continuously conveyed to a blast furnace, normal operation during blast furnace process is ensured, and the problem that the product quality is reduced or waste products are produced since hot air cannot be conveyed is solved.
Description
Technical field
The utility model relates to a kind of pressurising by-pass collar, belongs to blast furnace Machine Design manufacturing technology field.
Background technology
Hotblast stove is one of metallurgical important auxiliary facility of blast furnace, by hotblast stove, provides high-temperature hot-air to blast furnace continuously, and further reinforcing blast furnace is smelted.But in use, equalizer valve often can cause the equalizer valve valve plate to fall to being stuck in the middle of gap while closing because of stuck between valve plate base draw-in groove and adjusting bolt to hotblast stove, and occur can't the pressurising air-supply problem.This not only can affect the normal production of blast furnace, also can low-quality product occur because furnace run can't obtain enough temperature, to enterprise, bring unnecessary loss, simultaneously because process this fault, the necessary damping down of blast furnace, will waste valuable coke resource and the energy and reduce furnace processor.Therefore be necessary prior art is improved.
Summary of the invention
For solving existing blast funnace hot blast stove equalizer valve because often being stuck, and cause and can't affect normal problem of producing to the normal heat air delivery of blast furnace, the utility model provides a kind of pressurising by-pass collar.
The utility model is completed by following technical proposal: a kind of pressurising by-pass collar, comprise the pressurising pipe and be arranged on equalizer valve on the pressurising pipe, it is characterized in that the pressurising pipeline that is positioned at the equalizer valve front and back ends is provided with arm, arm is provided with by-pass valve, so that equalizer valve is stuck can't use the time, open by-pass valve, continue to the hotblast stove pressurising and to the blast furnace heat air delivery, avoid the reduction of wind-warm syndrome or because processing the out-of-blast blast furnace that affects of equalizer valve fault, normally smelt.
Described pressurising Guan Yiduan is connected with the hotblast stove blast inlet, and the other end is connected with cold-air duct, with to the hotblast stove pressurising.
Described hotblast stove air outlet is connected with blast-furnace tuyere by heating duct, to blast furnace, to carry to smelt, uses high-temperature hot-air.
The utlity model has following advantages and effect: adopt such scheme, can be by the arm on the pressurising pipe that is arranged on the equalizer valve front and back ends, and the by-pass valve on arm, can be easily at equalizer valve, break down and can't open while supplying gas, the unlatching by-pass valve changes by arm supplies gas, thereby incessantly the high-temperature hot-air of hotblast stove is delivered to blast furnace, ensures the normal operation of blast-furnace smelting, avoid hot blast to carry, cause the iron product quality to descend or the problem such as waste product occurs.Be a desirable blast furnace hotblast stove air supply plant in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
as Fig. 1, the pressurising by-pass collar that the utility model provides, comprise pressurising pipe 5 and be arranged on equalizer valve 4 on pressurising pipe 5, pressurising pipe 5 left ends are connected with hotblast stove 3 blast inlets, right-hand member is connected with cold-air duct 6, before being positioned at equalizer valve 4, the pressurising pipeline 5 of rear end is provided with arm 7, arm 7 is provided with by-pass valve 8, hotblast stove 3 air outlets are connected with blast furnace 1 air port by heating duct 2, when equalizer valve 4 is stuck can't use the time, open by-pass valve 8, thereby by arm 7, continued hotblast stove 3 pressurisings, high-temperature hot-air is carried to blast furnace 1 continuously, avoid out-of-blast and affect blast furnace 1 normally smelting.
