Abstract

The invention relates to the field of dry quenching devices, in particular to a dry quenching furnace with a new structure. The dry quenching furnace comprises a cooling room, an inclined flue, an annular air channel and a pre-storing room, and is characterized in that the diameter of the cooling room is the same as that of the pre-storing room; a support is arranged in the inclined flue; and a horizontal support and a half-height supporting wall are arranged in the annular air channel. Compared with the prior art, the dry quenching furnace has the advantages of having a simple, reasonable and firm furnace structure, greatly improving the strength of the annular air channel and a partition wall of the inclined flue, avoiding collapses in the production process, reducing the workload for maintaining the dry quenching furnace, and prolonging the service life and the service cycle of the dry quenching furnace.

Description

A kind of dried stove that puts out of new texture

Technical field

The present invention relates to the dry coke quenching auxiliary field, relate in particular to a kind of dried stove that puts out of new texture.

Background technology

At present, the dried oblique mid-feather of stove that puts out is to adopt to dried to put out the structure of encorbelmenting in the stove center, like this, just to put out the prestore diameter of chamber of stove big than dried for the dried diameter that puts out the stove cooling room, when the weight of the interior wall of annular passage and coke move downward the downward frictional force of interior wall all focused on the oblique mid-feather; In addition, tiltedly mid-feather expands repeatedly, shrinks through regular meeting when being subjected to thermal stresses.Owing to above two reasons, the oblique mid-feather phenomenon of cracking, rupturing through regular meeting when ordinary production is operated is put out repair time that stove do not reach regulation shutdown maintenance of just having to dried, and is greatly reduced dried work-ing life of putting out stove.At present dried ubiquitous another the big problem of stove of putting out is: the collapsing of annular passage interior wall.Under the nominal situation, interior wall one side is the cooling gas about 800 ℃, opposite side is the red-hot coke about 1000 ℃, because the refractory materials swell increment difference that the transverse thrust of coke and the temperature head on interior wall both sides cause is inconsistent, cause collapsing of interior wall, this situation occurring has also increased the dried workload of putting out the stove maintenance extraly.

Summary of the invention

The dried stove that puts out that the purpose of this invention is to provide a kind of new texture, long, maintenance number of times of its is few, dried production cycle, and to put out the used refractory materials bulk life time of stove long.

For solving the problems of the technologies described above, technical scheme of the present invention is:

A kind of dried stove that puts out of new texture comprises cooling room, oblique flue, annular passage and the chamber that prestores, and it is characterized in that the cooling room diameter is identical with the chamber diameter that prestores, and tiltedly support is set up in flue inside.

In the described annular passage horizontal support is set.

Be provided with half high knee wall in the described annular passage, height is concordant with horizontal support.

Compared with prior art, the invention has the beneficial effects as follows: furnace binding is simple, rational in infrastructure firm, has improved the intensity of annular passage and oblique mid-feather greatly, avoids collapsing in process of production, reduce the dried maintenance workload that puts out stove, prolong dried work-ing life and the life cycle of putting out stove.

Description of drawings

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure: the 1-oblique flue 4-of the chamber 2-annular passage 3-cooling room 5-horizontal support 6-that prestores supports the 7-half oblique mid-feather of high knee wall 8-overall height direction knee wall 9-interior wall 10-

Embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:

See Fig. 1, Fig. 2, the dried furnace binding of putting out stove comprises cooling room 4, oblique flue 3, annular passage 5 and the chamber 1 that prestores, cooling room 4 diameters are identical with chamber 1 diameter that prestores, so just avoided oblique mid-feather 10 to encorbelment to the dried stove stove heart that puts out, prestore chamber 1 refractory materials and coke only provides downward pressure to oblique mid-feather 10 to the downward frictional force of refractory materials, avoid oblique mid-feather 10 to produce shearing force because of encorbelmenting, thereby overcome the infringement of oblique mid-feather.

In order to prevent the influence of masonry quality to the globality and the structural strength of oblique mid-feather 10, tiltedly increasing support 6 in the flue 3, supporting 6 can be metal material, can be pouring material, also can be to build with brick.By these two work-ing lifes that measure can improve the chute partition wall, prolong the dried life cycle of putting out stove.

Increased horizontal support 5 at annular passage 2, this supports material and can be metallic substance, pouring material, lay bricks, this horizontal support 5 is divided into annular passage 2 two-layer from the centre, thereby the height that makes annular passage is reduced to half that does not add when supporting, because reducing of height, the stability of annular passage interior wall 9 improves greatly, because the dried coke that puts out in the stove has been balanced out by horizontal support 5 wall pressure of annular passage interior wall 9, the ability of annular passage interior wall 9 load side pressure improves greatly, and the deflection of annular passage interior wall 9 has also diminished greatly.

Annular passage only was provided with two overall height direction knee walls 8 originally, because annular passage 2 is divided into two-layer up and down, just having ready conditions increases by two and half high knee walls 7 again, and the height of these two and half high knee walls 7 is concordant with horizontal support, has improved the stability of annular passage interior wall greatly.

Claims

1. the dried stove that puts out of a new texture comprises cooling room, oblique flue, annular passage and the chamber that prestores, and it is characterized in that the cooling room diameter is identical with the chamber diameter that prestores, and tiltedly support is set up in flue inside.

2. the dried stove that puts out of a kind of new texture according to claim 1 is characterized in that, in the described annular passage horizontal support is set.
