Abstract
The utility model relates to an end fume collecting device for a stamp-charging coke oven, which has no ascension pipe on the side of the machine. The device comprises valve assemblies and an air collecting pipeline; the valve assemblies are used in coordination with a fume guiding vehicle arranged on the roof of the oven; the amount of the valve assemblies and that of the doors of the coke oven are in one-to-one correspondence; the air collecting pipeline is arranged right above a collecting cover; the valve assemblies are arranged at the joint of the air collecting pipeline and the collecting cover; a valve body comprises a push rod, a connecting rod transmission mechanism, a wire rope, a lifting rod and a lifting valve plate, wherein the lifting rod and the lifting valve plate are fixedly connected with each other and are arranged in the air collecting pipeline above the collecting cover; and the push rod pushes the connecting rod transmission mechanism to drive the lifting valve plate to go up and down. Due to the arrangement of the device, the spatial arrangement of the air collecting pipe and lifting valve assemblies is more compact; other facilities can be arranged more conveniently, and the occupied space thereof is reduced; meanwhile, steel material is saved; and the whole set of collecting valve assemblies are light and handy and convenient to be installed.
Description
Technical field
The utility model relates to the capturing device that a kind of pusher side does not have upcast type burner smoke of stamp-charged coke oven.
Background technology
In recent years, because the development of iron and steel and metallurgy industry make internal and international coke consumption amount in continuous increase, and tamping coke furnace has the use wide scope of material, polygamy was gone into high volatile component weak bonding property coal production high-quality blast furnace and was widely adopted with burnt advantage.Along with improving environmental quality, thoroughly effect a radical cure the enforcement that iron and steel enterprise pollutes measure, newly-built and more and more strictness of enlarging coke oven environmental requirement, so tamping coke furnace paroxysmal smoke and dust treatment just seems more and more important.
At present, be typically provided with in the tamping coke oven dust design coaling, the coke discharging and dedusting system, and auxiliary can further improve the operating environment of coke oven behind the burner smoke capturing device, improve coke oven ambient air quality greatly, more effectively control the generation of coke oven smoke.She Ji burner smoke capturing device in the past, collecting pipe is that separate type is arranged with capturing poppetvalve, connecting tube need be set, and this kind decoration form floor space is big, because the coke oven machine side process pipe and the wire rack complexity of rubbing, arrangement space is relatively more nervous; Simultaneously, complete assembly weight is big, and support is unfavorable for installing more, therefore, if can improve the position of collecting pipe, makes that the layout of collecting pipe and poppetvalve group is compact more, with the layout of convenient other facilities.
Summary of the invention
The purpose of this utility model provides a kind of burner smoke of stamp-charged coke oven capturing device, this device is by changing the position of collecting pipe, make that the space layout of collecting pipe and poppetvalve group is compact more, can the paroxysmal burner smoke of pusher side will be created in the pit kiln production process, be transferred in the fixed smoke dust-removing equipment by the valve group, improve the coking technique environment significantly, reduce the discharging of coke oven pollutent; And this valve group is provided with for being included in the collecting pipe, has reduced the occupation of land space, saves steel simultaneously, makes a whole set of valve group that captures lightly help installing.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of burner smoke of stamp-charged coke oven capturing device, comprise valve group and collecting pipe, valve group and the supporting use of smoke guiding bogie that is located at furnace roof, valve group quantity is corresponding one by one with the quantity of coke oven door, described collecting pipe is positioned at directly over the fume trap cover, and the valve group is arranged on the junction of collecting pipe and fume trap cover.
Described valve body comprises push rod, jointed gear unit, wireline, lifting rod, lifting valve plate, and lifting rod is fixedlyed connected with the lifting valve plate, is positioned at the collecting pipe on fume trap cover top; Lifting rod top connects jointed gear unit by wireline, and the other end of jointed gear unit is corresponding with the push rod position, the promotion of jointed gear unit is realized promoting the lifting of valve plate by push rod.
Described jointed gear unit is provided with stop means.
Described lifting valve plate be shaped as taper, sphere shape, circle, ellipse or rectangle.
Described collecting pipe section is circle, semicircle, ellipse, rectangle or Polygons.
Compared with prior art, the utility model has the advantages that:
1) this device can be transferred in the fixed smoke dust-removing equipment by the valve group being created in the paroxysmal burner smoke of pusher side in the pit kiln production process, improves the coking technique environment significantly, reduces the discharging of coke oven pollutent;
2) the valve group is arranged on the junction of collecting pipe and fume trap cover, and the compact in design of valve group and collecting pipe makes things convenient for the layout of other facilities and reduced the occupation of land space, saves steel simultaneously, makes a whole set of valve group that captures lightly help installing.
3) a whole set of valve group adopts the mechanical linkage type of belt drive to realize flue gas trapping and conducting, close valve by valve plate deadweight finish, switch is reliable, air leak rate of air curtain is low, no energy consumption, in light weight, be easy to arrange, the saving space.
