Description
Technical field
The utility model is related to a kind of feed chute for horizontal revolving cylinder cooler, is mainly used in metallurgical mine
The cylinder cooler cooled down in industry to reduced iron pelletizing, agglomerates of sintered pellets.
Background technology
The temperature that DRI pelletizing is exported through rotary hearth furnace or rotary kiln is up to 1100 DEG C, is entered by feed chute and justified
Cylinder cooler is cooled down, and feed chute is that high temperature reduction iron ball group enters the important channel that cylinder cooler is cooled down.Charging is slipped
Groove walks whether material is smooth will to have a strong impact on yield, or even can influence the normal production of whole production line.Existing feed chute knot
Structure is square pipe segment structure, and surrounding inner face welding anchor studs pour Wear-resistant, high-temperature resistant castable, and the length of chute is according to turning bottom
Stove or rotary kiln baiting point, apart from specific design, are generally divided into 2~4 sections of chute splicings with cooler entrance.Existing cylinder
Cooler feed chute existing defects：Chute section four sides is pouring material inside, because chute material passage is smaller, chute is poured
Expect constructional difficulties；Chute putty can not be dredged during production；Chute maintenance can only dismantle be lifted into maintenance position could implement, dismounting is hung
Dress is all extremely difficult, it is impossible to realize on-bne repair and maintenance.
Utility model content
In view of this, in order to solve feed chute inner face pouring material constructional difficulties, and can not on-bne repair and asking for safeguarding
Topic, the utility model provides a kind of horizontal revolving cylinder cooler feed chute.
The utility model is achieved through the following technical solutions：
The utility model provides a kind of horizontal revolving cylinder cooler feed chute, including at least two sections square structures
Pipeline section, two sections of adjacent pipeline sections are connected by flange, and cooling case lid is configured with the one side of the pipeline section.
Further, the cooling case lid has cavity structure, is removably connected with the pipeline section.
Further, the import for being used for cryogen and circulating, outlet are provided with the cavity；The cryogen be cooling water or
Compressed gas.
Further, cooling case lid set on two sections of adjacent pipeline sections is connected by flexible pipe.
Further, Wear-resistant, high-temperature resistant castable has been poured on its excess-three face inner face of the pipeline section.
Further, the cooling case lid outer covering has thermal insulation layer.
By using such scheme, this feed chute makes its one side be configured with the cooling of cavity structure when entering walking material
Case lid, and flow using cryogen in the cavity and take away heat discharge, the feed chute is integrally adequately cooled, it is sharp
Material is walked in it.
Advantageous effects of the present utility model are：First, the utility model feed chute is simple in construction, castable construction
Convenient, cooling effect is good, beneficial to the service life of extension device；Second, the utility model feed chute realizes equipment not
Need to stop production just can online be dredged to chute；During maintenance, it is not necessary to whole section of dismounting lifting, maintenance can be just completed in installation position
And maintenance, overhaul procedure is simplified, the repair time is shortened.
The advantage of the utility model annex will be provided in the description of embodiment part below, partly will be from following
Description in become obvious, or by it is of the present utility model practice recognize.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with accompanying drawing to this practicality
It is new to be described in further detail, wherein：
Accompanying drawing 1 is the structural representation of the utility model feed chute；
Accompanying drawing 2 is the A-A views of accompanying drawing 1；
Reference：1- pipeline sections, 2- cooling case lids, 3- imports, 4- outlets, 5- flexible pipes, 6- pouring materials；Wherein, 11- front tubes
Pipeline section after section, 12-.
Embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail；It should be appreciated that it is preferred that real
Example is applied only for explanation the utility model, rather than in order to limit protection domain of the present utility model.
As shown in Figure 1, 2, cylinder cooler feed chute, includes the pipeline section 1 of at least two sections square structures, this is adjacent
Two sections of pipeline sections 1 are fixed by flange, bolt-connection；And dismountable cooling case lid 2 is configured with the one side of the pipeline section 1, it leads to
Cross flange to be connected with pipeline section 1, with cavity structure；Cryogen, such as cooling water can be imported in the cavity, you can quick reduction is slipped
The temperature of groove, certainly in various embodiments, the cryogen can be high pressure gas, and its air-flow quickly flowed can be taken away rapidly
Heat, makes chute integrally be adequately cooled；Its excess-three face of the pipeline section has poured inside castable 6.
Specifically, being respectively equipped with import 3 and outlet 4 at the two ends of cavity, cooling water can be passed through through an import 3 of pipeline section 1,
Cooling water is connected by flexible pipe 3 in the cavity of cooling case lid 21 and 22 set respectively on adjacent preceding pipeline section 11 and rear pipeline section 12
Cooled down, 4 export cooling waters are finally exported by another pipeline section 1.By using such scheme, this feed chute is entering walking
During material, its one side is set to be configured with the cooling case lid of cavity structure, and use cryogen flows in the cavity and takes away heat row
Go out, the feed chute is integrally adequately cooled, material is walked beneficial to it.
The internal heat of the feed chute can only be taken away for the cryogen that ensures in the cavity, is increased cooling case lid 2 is outer
If thermal insulation layer (not shown), equivalent to scattering and disappearing for heat is accelerated, so that chute cooling velocity is accelerated.
The utility model feed chute is simple in construction, castable easy construction, and cooling effect is good, extends making for equipment
Use the life-span；Realizing equipment and need not stopping production just can online be dredged to chute；During maintenance, it is not necessary to whole section of dismounting lifting,
It can just complete to overhaul in installation position and safeguard, simplify overhaul procedure, shorten the repair time.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, it is clear that this area
Technical staff can to the utility model carry out it is various change and modification without departing from spirit and scope of the present utility model.This
Sample, if these modifications and variations of the present utility model belong to the utility model claim and its equivalent technologies scope it
Interior, then the utility model is also intended to comprising including these changes and modification.
