Description
Technical field
The utility model is related to a kind of grate-cooler, belongs to cement manufacture plant technical field.
Background technology
Grate cooler is a kind of rapid cooling type cooler, is the essential process equipment of cement plant clinker cooling.Clinker
After entering cooler by rotary kiln, the certain thickness bed of material is paved into grate plate, the cold air for blasting, with mutually orthogonal direction
The moving bed of material enables clinker to be quenched on through grate.
Traditional cooler is divided into three kinds of swinging, oscillatory type and driving, but because first two has been eliminated, driving
Grate-cooler has become the main cement clinker cooler type of precalciner kiln Selecting Complete Set.Driving grate-cooler is by technology
Personnel's is updated, and " thin bed of material grate-cooler ", the second generation " deep bed sintering grate-cooler ", the third generation of the first generation are experienced respectively
" the efficient grate-cooler of air fine strain of millet " and forth generation grate-cooler.The utility model applies the most the 3rd primarily directed to current cement plant
The technological improvement of the high-temperature region and middle warm area grate plate that are carried out for " the efficient grate-cooler of air fine strain of millet " leading portion and stage casing.
The third generation " the efficient grate-cooler of air fine strain of millet " grate is the critical piece of cooler, promote grate plate be by a line one in the ranks
Every fixed grate plate and the movable grate plate composition of arrangement.High-temperature region carries out recuperation of heat, middle temperature using fixed and movable inflation beam technology
Area uses high-drag low drain material grate plate, and low-temperature space uses fowler modified grate plate, while grate-cooler implements deep-bed sintering, cooling
Mainly inflation beam installs high-drag inflatable grate plate in machine structure, and the air feed of fixed type inflatable beam is by fixed distribution airduct reality
Existing grate plate air feed, the air feed of movable inflation beam distributes airduct or articulation airduct or formula metal around property by loop type
The airduct that is flexible coupling realizes grate plate air feed.The air feed of high-drag low drain material grate plate and fowler modified grate plate is supplied by grate-cooler air chamber
Wind is realized.
The third generation " the efficient grate-cooler of air fine strain of millet " goes out after rotary kiln rotating discharge to pile up on one side thick one due to not considering clinker
The characteristics of side is thin, only with left and right blower fan air supply mode, and it is the grate plate of 6mm that grate plate all uses unified fixed seam of combing, actual
Cooling effect and bad, material cooling degree is also uneven.
Utility model content
The utility model aims to solve the problem that the cooling effect that the efficient grate-cooler of air fine strain of millet is present in the prior art is not good, and product is cold
But a kind of uneven problem of degree, there is provided new grate-cooler, by the improvement to fan outlet, greatly improves the cold of material
But effect.
In order to realize foregoing invention purpose, the technical solution of the utility model is as follows：
A kind of grate-cooler, including first paragraph grate, second segment grate and the 3rd section of grate, it is characterised in that：Described first

The front end air-supply of grate both sides and first paragraph grate.
It should be noted that the both sides of the first paragraph grate described in this is new refer to both sides wider, side is near kiln
Mouthful, opposite side is connected with second segment grate.
In order to the utility model is better achieved, the first paragraph grate has three air-cooled areas, respectively positioned at first paragraph
First air-cooled area of grate front end, the 3rd air-cooled area of first paragraph grate rear end and positioned at the first air-cooled area and the 3rd air-cooled area
The second middle air-cooled area.
By the first cooling blower air feed, first cooling blower at least has three air outlets in the first air-cooled area,
Respectively positioned at the both sides and the front end in the first air-cooled area in the first air-cooled area；The second air-cooled area is supplied by the second cooling blower
Wind, second cooling blower at least has 8 air outlets, respectively positioned at the both sides in the second air-cooled area；The 3rd air-cooled area
By the 3rd cooling blower air feed, the 3rd cooling blower at least has 16 air outlets, respectively positioned at the two of the 3rd air-cooled area
Side.
First cooling blower, the second cooling blower and the 3rd cooling blower can be located at any position that can be set, only
Ensure air outlet number and the air outlet position for needing.
It should be noted that the front end in the first air-cooled area refers to it can be seen that one end of the stepped sides of first paragraph grate.
The second air-cooled area, the 3rd air-cooled area and second segment grate connection end are the comb of 8mm at least provided with two row gaps
Plate；The middle part in the second air-cooled area and the 3rd air-cooled area is the grate plate of 8mm at least provided with two row gaps, between remaining grate plate between
Gap is 6mm.
The beneficial effects of the utility model：
（1）The utility model increases cooling blower cooling on the basis of the existing third generation " the efficient grate-cooler of air fine strain of millet "
Region, original both sides air intake is changed to three side air intakes, the effect of three side air intakes not three independent blower fan effect sums, and
It is to be far longer than.After changing air supply mode, solve material in actual production process and easily pile up that position cooling effect is not good to ask
Topic, the product cooling effect that production is obtained is good, improves production efficiency, and product quality stable and uniform, is adapted to large-scale production.
（2）In the utility model, first paragraph grate has three air-cooled areas, respectively positioned at the first of first paragraph grate front end
Air-cooled area, the 3rd air-cooled area of first paragraph grate rear end and in the middle of the first air-cooled area and the 3rd air-cooled area second are air-cooled
Area, is divided into a whole grate three parts and is cooled down respectively, increases the quantity delivered of cooling wind, and sub-sectional cooling is conducive to
The balance of air feed.
（3）In the utility model, the first air-cooled area is at least had by the first cooling blower air feed, first cooling blower
Three air outlets, respectively positioned at the both sides and the front end in the first air-cooled area in the first air-cooled area；The second air-cooled area is by second
Cooling blower air feed, second cooling blower at least has 8 air outlets, respectively positioned at the both sides in the second air-cooled area；It is described
By the 3rd cooling blower air feed, the 3rd cooling blower at least has 16 air outlets, respectively positioned at the 3rd in 3rd air-cooled area
The both sides in air-cooled area.The air outlet position and quantity, are the positions according to the easy stacking material found in actual production process
It is designed, it is ensured that the cooling of material is more uniform.
（4）In the prior art, all of grate plate gap is 6mm, the second air-cooled area, the 3rd air-cooled in the utility model
Area is the grate plate of 8mm at least provided with two row gaps with second segment grate connection end；The second air-cooled area and the 3rd air-cooled area
