Description
Technical field
The utility model relates to the COREX iron-smelting furnace, relates in particular to COREX iron-smelting furnace Y type tremie pipe stifle.
Background technology
Ironmaking technique of fusion and reduction, promptly the COREX technology is present unique a kind of smelting reduction process of realizing suitability for industrialized production.Compare with blast furnace process, the COREX flow process can be utilized mill coal direct production molten iron, simultaneously can use natural lump ore and part fine ore to produce, utilizable aboundresources, Sustainable development to metallurgical industry is significant, the pollution of COREX flow process is far smaller than blast furnace process in addition, is a kind of iron-smelting process of environmental protection.Degree of metalization mainly takes place and reaches the fusion of the sponge iron more than 90% and further reduction, the gasification of carbon, the reduction of non-metallic element, desulphurization reaction between the slag gold or the like in melting gasification furnace.The main products of vapourizing furnace is except molten iron, and most important is exactly the coal gas that produces, and the required reducing gas of shaft furnace is exactly that this coal gas produces through certain back of handling.The material that enters in the vapourizing furnace mainly contains coal (coal briquette), a spot of coke, and quartzy (SiO2) after explained hereafter is stable, can add a spot of recovery powder.These material all add from vault, in addition, and 99% the pure oxygen in addition that blasts from the air port.Sponge iron is to enter in the vapourizing furnace by eight Y type sponge iron tremie pipes, and 8 cover sponge iron screw feeders are installed in the bottom of shaft furnace, and they link to each other with above-mentioned eight Y type tremie pipes, and sponge iron is added in the vapourizing furnace.Since technologic factor, putty in the eight Y type sponge iron tremie pipes of being everlasting.
The COREX blast furnace was when mediation Y type sponge iron tremie pipe putty in the past, need use the stifle of Y type sponge iron tremie pipe is removed, employing is respectively hung a chain block on two asymmetric I-beams above Y type tremie pipe two sides, after the stifle flange bolt is removed, with chain block stifle is sling and to be shifted out the mediation working position, the artificial method is dredged then; Return when dress at stifle especially, because the position of chain block is asymmetric, can not be in place exactly, be by manually being pushed into Y type tremie pipe top, in place, labour intensity is big and time-consuming; And the temperature of Y type tremie pipe is very high, and has a large amount of coal gas to overflow in the stove, makes to have unsafe hidden danger in the operating area.
Summary of the invention
The problems referred to above of the prior art that the utility model is intended to solve provide a kind of COREX iron-smelting furnace Y type tremie pipe stifle special-purpose dismounting dolly.When the utility model is guaranteed Y type sponge iron tremie pipe putty when mediation dismounting stifle of COREX blast furnace, can be in place quickly and accurately, shorten the repair time, reduce labor intensity.
For solving the problems of the technologies described above, the special-purpose dismounting dolly of a kind of COREX iron-smelting furnace of the utility model Y type tremie pipe stifle, it comprises:
Little frame, it is an arch member;
A hanger plate, it is arranged on the arch lower surface of little frame one end, and described hanger plate center is provided with through hole;
Following road wheel, the arcuate surface of the opposite side of described little frame is provided with open holes, and described road wheel down is vertically pivotally connected in described open holes with its axis;
The anti-baffle plate of escaping of dolly, it comprises with vertical plate on the hinge connecting frame the other end end face and the leveling board that is parallel to the framework end face;
A dolly tack bolt, it vertically inserts, and dolly is anti-to be escaped on the leveling board of plate;
Last road wheel, it with a support built on stilts be arranged on the framework top and and the equidirectional setting of following road wheel, described support comprise vertical plate and leveling board and and dolly prevent that escaping baffle interval is oppositely arranged;
Two pairs are moved and stablize rollers, and described support and dolly be anti-to be escaped to be provided with a horizontally disposed mobile roller of stablizing separately on the position at two relative angles of the leveling board of baffle plate.
The special-purpose dismounting dolly of described COREX iron-smelting furnace Y type tremie pipe stifle, described uplink and downlink travelling wheel is two.
Of the present utility model product is from safety, angle is gone design and design easily.The utility model is simple in structure, it is during to the mediation of Y type sponge iron tremie pipe putty of COREX during the dismounting stifle, can be in place quickly and accurately, the security of dismounting stifle when improving COREX mediation Y type sponge iron tremie pipe putty, shortening repair time and maintainer's labour intensity.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the forward view of the utility model dismounting vehicle structure;
Fig. 2 is the bottom view of the utility model dismounting vehicle structure.
Embodiment
As depicted in figs. 1 and 2, the special-purpose dismounting dolly of a kind of COREX iron-smelting furnace Y type tremie pipe stifle, it comprises:
Dolly framework 1, it is an arch member;
