A plurality of drivable breaker roll between cooler cylindrical shell and hopper, breaker roll be in the cooler inner barrel, and leave the gap between breaker roll; And
Cold air duct, described cold air duct is in hopper two upper lateral parts, breaker roll bottom.
As preferably, described cooler comprises 4～6 breaker rolls.
As preferably, described breaker roll is respectively by independent actuator drives.
As preferably, the cross section of described cooler cylindrical shell is square, and is shrunk to less square cylinder on top.
As preferably, the length of described breaker roll is suitable with cylindrical shell length.
As preferably, described cold air duct is perpendicular to breaker roll, and arranges a plurality of on the cooler cylindrical shell symmetrically.
As preferably, described cooler cylindrical shell and/or hopper inside also include refractory lining.
As preferably, described vertical cooler also is included in the one or more air bubbles that are provided with on the cooler cylindrical shell of breaker roll top.
The utility model is by contacting between the high temperature chamotte of ascending air and whereabouts, and makes dynamic cooling air all carry out countercurrent heat exchange by the bed of material of high temperature chamotte, can realize the purpose of efficient cooling down high-temperature grog.Simultaneously, the bed of material of the bed of material of the utility model cooler other type cooler more of the prior art is all thick, and it is longer that cold air passes the path that the bed of material walks, and can carry out sufficient heat exchange with the bed of material, thereby improve the cooling effectiveness of cooler.And owing to have good sealing property, the ubiquitous material phenomenon of leaking out in the prior art can not appear, improved the thermal efficiency of cooler.
In addition, the utility model cooler does not have surplus air, does not therefore need auxiliary devices such as dust-precipitator, and it is few that simple in structure, materials are economized, taken up an area of, can reduce investment outlay greatly cost and more environmental protection.The utility model cooler inside does not have the wear-out part of cooler in the prior art yet, and is easy to maintenance and can save the spare part expense in the use.
Description of drawings
Fig. 1 is the structure chart of the preferred embodiment of the vertical cooler of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
The utility model be used for the cooling down high-temperature grog vertical cooler structure as shown in Figure 1, cooler cylindrical shell 3 is erect and is placed, its inside also includes refractory lining 8, to bear the temperature of high temperature chamotte.As preferably, the cross section of cooler cylindrical shell 3 is square.Feed end is positioned at the top of cooler cylindrical shell, is connected with rotary kiln 1.Hopper 6 is positioned at the bottom of cooler cylindrical shell, and is connected with lock wind discharge gate 7 in its underpart, can send into miscellaneous equipment through the grog that lock wind discharge gate 7 will cool off after the also fragmentation.Hopper 6 inside also include the heat proof material liner.
A plurality of breaker rolls 5 are arranged between cooler cylindrical shell and hopper, and breaker roll 5 is in cooler cylindrical shell 3 inside, and leaves the gap between breaker roll.As preferably, present embodiment comprises 4～6 breaker rolls, and those skilled in the art also can select the quantity of breaker roll according to the needs of using.Each breaker roll is respectively by independent actuator drives.And can both be broken in order to ensure all materials, the length of breaker roll is suitable with cylindrical shell length.
Also be furnished with air bubble 9 on cooler cylindrical shell above the breaker roll 5, purpose is to prevent to expect that thickness ununiformity is even.The quantity of air bubble 9 can be selected one or more according to the needs of using.
Cold air duct 4 is at 6 liang of upper lateral parts of hopper, breaker roll 5 bottoms, and link to each other with air blast.Cold air duct 4 can be arranged arbitrarily in breaker roll 5 bottoms, as preferably, cold air duct is perpendicular to breaker roll, and arranges a plurality ofly on the cooler cylindrical shell symmetrically, can be blown into (shown in arrow among Fig. 1) in the bed of material by the gap between the breaker roll with the cold wind that makes things convenient for cold air duct.
In the cooler course of work, the grog after burning till in the rotary kiln 1 falls into cooler cylindrical shell 3 through kiln hood cover 2, and the cold air duct 4 of below is blown into gas in cylindrical shell simultaneously.The gas that is blown into will be because the pressure of air blast and the buoyancy of gas will form ascending air from the bottom up from inner barrel, and this ascending air contacts with the high temperature chamotte that falls from top to bottom owing to the gravity effect and carries out countercurrent heat exchange.Therefore compare with the cooler of prior art, can carry out heat exchange more fully between them, so can make the cooling effectiveness of cooler improve.
After cooling off gradually, high temperature chamotte drops to breaker roll 5, through breaker roll 5 fragmentations.The fragmentation of bulk grog is sent into miscellaneous equipment by lock wind discharge gate 7 then after the slit of breaker roll 5 falls into hopper 6.
As preferably, the structure of contraction is arranged on the top of cooler cylindrical shell 3, promptly be shrunk to less square cylinder.Speed can be accelerated when air communication is crossed this position like this, thereby makes this zone produce the effect of spurting, and makes material pass through can disperse uniformly behind this zone.
According to the explanation of the structure of the above-mentioned vertical cooler that the utility model is used for the cooling down high-temperature grog and the course of work thereof as can be known, the utility model is because the vertical structure of its uniqueness can bring following advantage and effect:
1, cooling effectiveness height.The bed of material of the bed of material of the utility model cooler other type cooler more of the prior art is all thick, and it is longer that cold air passes the path that the bed of material walks, and can carry out sufficient heat exchange with the bed of material, thereby improve the cooling effectiveness of cooler.
2, thermal efficiency height.Owing to have good sealing property, the ubiquitous material phenomenon of leaking out in the prior art can not appear in the utility model cooler, thereby has improved the thermal efficiency of cooler.
3, cost is low.Therefore the utility model cooler does not need auxiliary devices such as dust-precipitator owing to there is not surplus air, and it is few that simple in structure, materials are economized, taken up an area of, can reduce investment outlay greatly cost and more environmental protection.
4, easy to maintenance.The utility model cooler inside does not have the wear-out part of cooler in the prior art, so easy to maintenance and can save the spare part expense in the use.
Should be appreciated that the vertical cooler that the utility model provides mainly is to be used to cool off the cement rotary kiln high temperature chamotte, but also can be applied to the cooling of other material according to structure of the present utility model and principle thereof, this belongs to protection domain of the present utility model equally.Be that high temperature chamotte described in the utility model can comprise other any high-temperature material that cement rotary kiln high temperature chamotte and those skilled in the art can derive.
It should also be understood that; the above only is preferred embodiment of the present utility model; be not so limit scope of patent protection of the present utility model; so the so-called equivalent structure of all utilizations specification of the present utility model and diagramatic content changes, or directly or indirectly apply in the scope that other correlative technology fields all in like manner all are contained in the utility model and are contained.
