Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-3, a cement clinker cooling device at a high-temperature section of a grate cooler comprises a box body and a cooling grate plate, wherein the box body is divided into a front box body 1, a middle box body 2 and a rear box body 3 from a feeding end to a discharging end, the front box body 1, the middle box body 2 and the rear box body 3 are separated by a partition plate 4, a cooling fan 5 is respectively arranged in the box body and provided with an air inlet 6, the cooling grate plate 7 covers the tops of the front box body 1, the middle box body 2 and the rear box body 3, the cooling grate plate 7 is distributed in a step shape from the feeding end to the discharging end, a dispersing section 8 with the width sequentially increasing towards two sides is arranged in a path from the feeding end to the discharging end of the cooling grate plate 7, and the overlooking angle of the dispersing section 8 is horn-shaped.
Specifically, the cooling grid plate 7 is formed by arranging and combining a plurality of fixed cooling grid plate units 7-1, the fixed cooling grid plate units 7-1 are arranged on the basis of grid beams 7-3 stretching over the box body, height difference exists between the front row and the rear row to form a step shape, and grid seams 7-2 are reserved between the adjacent fixed cooling grid plate units and used for passing cooling air from the box body.
The width of the grate gap 7-2 is gradually increased from the feeding end to the discharging end, so that the passing air volume is larger, the cooling requirements of more cement clinkers are met, and the cooling fans are all centrifugal fans.
The specific position of the dispersing section 8 can be determined according to actual needs, the initial position is usually at the feed inlet 9, the end position of the dispersing section corresponds to the position above the front box body 1 or the position above the middle box body 2 or the position above the rear box body 3, if the cement clinker is relatively less, the dispersing section can be designed to be shorter, the cement clinker is more, the speed is higher, and the dispersing section can be designed to be longer.
The working principle is as follows:
the hot cement clinker falls onto the cooling grate plate 7 from the feeding hole 9 and is gradually dispersed along the full length of the stepped cooling grate plate 7 to form a material layer with a certain thickness, wherein due to the stepped design that the front part of the cooling grate plate 7 is higher and the rear part is lower, the cement clinker moves from front to back under the combined action of the gravity of the cement clinker and the extrusion force of the front material, in the process, the stacking condition of the cement clinker close to the rear position is more serious, and when the cement clinker passes through the dispersing section, the cement clinker can dispersedly move towards two sides due to the opening in the width direction, so that the stacking problem of the cement clinker in the rear row is greatly relieved, but in the whole, the stacking thickness of the cement clinker positioned at the rear part is still larger than that of the cement clinker at the front part.
Meanwhile, the cooling fans 5 in the front box body 1, the middle box body 2 and the rear box body 3 work to blow cold air to the cooling grate plate 7 to cool the cement clinker, and as the cement clinker at the rear part is dispersed, the cooling air is easier to pass through, the contact area is increased, and the cooling efficiency is also improved.
In a more preferred embodiment, in the fixed cooling grate plate units of the dispersing section, the height of the fixed cooling grate plate units in the same row is reduced from the middle to two sides, so that the cement clinker is more easily dispersed.
In a more preferred embodiment, the rear box body comprises a left box body and a right box body, the left box body and the right box body are respectively provided with an air inlet, and cooling fans are respectively arranged inside the left box body and the right box body.
In a more preferred embodiment, the power of the cooling fans in the front box body, the middle box body and the rear box body is sequentially increased, and the power of the used cooling fans is higher due to the fact that more cement clinkers are stacked at the rear end, a material layer is thicker, and the needed air volume is larger.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
