In the preferred embodiment of the above-mentioned cooling device for cement rotary kiln, described cooling device comprises 4-6 breaker roll.
In the preferred embodiment of the above-mentioned cooling device for cement rotary kiln, each described breaker roll is driven by independent drive unit respectively.
In the preferred embodiment of the above-mentioned cooling device for cement rotary kiln, the length of each described breaker roll is equal with the cross section length of side of described compresses lower section.
In the preferred embodiment of the above-mentioned cooling device for cement rotary kiln, described cold air duct is arranged perpendicular to described breaker roll.
In the preferred embodiment of the above-mentioned cooling device for cement rotary kiln, described cooling device also comprises the multiple air bubbles be arranged in described compresses lower section.
The utility model, by the contact between ascending air and the high temperature chamotte of whereabouts, makes dynamic cooling air all carry out countercurrent heat exchange by the bed of material of high temperature chamotte, can realize the object of high efficiency cooling high temperature chamotte.Meanwhile, machine barrel of the present utility model adopts diameter reduced to arrange, namely, upper diameter is significantly less than lower diameter, this makes ascending air can accelerate through this minor diameter section, thus the grog caused to fall and break can more uniformly disperse behind this region, and then improves heat exchanger effectiveness.
Accompanying drawing explanation
Fig. 1 is the structure chart of the preferred embodiment of cooling device of the present utility model.
Detailed description of the invention
With reference to the accompanying drawings preferred embodiment of the present utility model is described.One skilled in the art will appreciate that these embodiments only for explaining know-why of the present utility model, and not intended to be limiting protection domain of the present utility model.
Fig. 1 is the structure chart of the cooling device for cement rotary kiln of the present utility model.As shown in Figure 1, this cooling device comprises machine barrel 3, hopper 6, breaker roll 5 and cold air duct 4 generally.Machine barrel 3 is vertically arranged, and its inside also includes the liner 8 that refractory material is made, to bear the temperature of high temperature chamotte.Feed end is positioned at the top of machine barrel 3, is connected with cement rotary kiln 1.Hopper 6 is connected to the below of machine barrel 3, and bottom it, be connected with lock wind discharge gate 7, through lock wind discharge gate 7, the grog after cooling also fragmentation can be sent into miscellaneous equipment.Hopper 6 inside also includes the liner of heat proof material.
As shown in Figure 1, machine barrel 3 of the present utility model comprises three sections connected successively from top to bottom, that is, top section, centre portion and compresses lower section.The cross section of described top section and compresses lower section is square, and the cross section length of side of described top section is less than the cross section length of side of described compresses lower section.Correspondingly, the segment cross-section due to two ends is square, therefore described centre portion necessarily truncated pyramid shape, specifically butt orthopyramid shape.In a preferred embodiment, the cross section length of side of described compresses lower section is the twice of the cross section length of side of described top section.
The bottom (specifically in the bottom of compresses lower section) of machine barrel 3 is provided with multiple breaker roll 5, and breaker roll 5 is inner at machine barrel 3, and leaves gap between breaker roll 5.Preferably, the present embodiment comprises 4-6 breaker roll, and those skilled in the art also can according to the quantity needing selection breaker roll of application.Each breaker roll 5 is driven by independent drive unit respectively.Can both be broken in order to ensure all materials, the length of breaker roll 5 is equal with the cross section length of side of the compresses lower section of machine barrel 5.
Above breaker roll 5, the compresses lower section of described machine barrel 3 is also furnished with air bubble 9, object is filled with air in machine barrel 3, to prevent material thickness ununiformity even.The quantity of air bubble 9 can according to application need select one or more.
Cold air duct 4 is arranged on the top of hopper 6, is positioned at the below of breaker roll 5, and is connected with air blast (not shown).Cold air duct 4 can be arranged arbitrarily below breaker roll 5.Preferably, cold air duct 4 perpendicular to breaker roll 5, and is arranged multiple symmetrically on hopper 6, can be blown into (as shown by the arrows in Figure 1) in the bed of material to facilitate the cold wind of cold air duct 4 by the gap between breaker roll 5.
In the course of the work, the grog after burning till in cement rotary kiln 1 falls into machine barrel 3 through kiln head cover 2, and the cold air duct 4 of below is blown into gas in machine barrel 3 simultaneously.The gas be blown into will form ascending air from machine barrel 3 inside from the bottom up due to the pressure of air blast and the buoyancy of gas, and this ascending air contacts with the high temperature chamotte fallen from top to bottom due to Action of Gravity Field and carries out countercurrent heat exchange.Therefore cooling effectiveness compared with the cooler of prior art, between them, heat exchange more fully can be carried out, so can be improved.Breaker roll 5 is dropped to after high temperature chamotte cools gradually, broken through breaker roll 5.Fall into hopper 6 through the gap of breaker roll 5 after bulk chamotte crushing, then send into miscellaneous equipment by lock wind discharge gate 7.
As mentioned above, machine barrel 3 is arranged to the undergauge structure of syllogic, can be accelerated like this at air-flow by this position hourly velocity, thus makes this region produce effect of spurting, and the material caused to fall and break, by disperseing equably behind this region, improves heat exchanger effectiveness further.
According to above-mentioned to the structure of the cooling device for cement rotary kiln of the present utility model and the explanation of the course of work thereof, the utility model is due to the vibrational power flow of its uniqueness, following advantage and effect can be brought: by the contact between ascending air and the high temperature chamotte of whereabouts, make dynamic cooling air all carry out countercurrent heat exchange by the bed of material of high temperature chamotte, the object of high efficiency cooling high temperature chamotte can be realized; Machine barrel adopts diameter reduced to arrange, that is, upper diameter is significantly less than lower diameter, and this makes ascending air can accelerate through this minor diameter section, thus the grog caused to fall and break can more uniformly disperse behind this region, and then improves heat exchanger effectiveness.
So far, describe the technical solution of the utility model by reference to the accompanying drawings, but those skilled in the art are it is easily understood that protection domain of the present utility model is obviously not limited to these detailed description of the invention.Under the prerequisite not departing from principle of the present utility model, those skilled in the art can make equivalent change or replacement to correlation technique feature, and these changes or the technical scheme after replacing it all will fall within protection domain of the present utility model.
