Abstract
The utility model relates to a rotary kiln technical field discloses a rotary kiln of rotatory cylinder drier in area, including rotary kiln and finished product bin, still include the deposit room and rotatory cylinder drier be connected with the rotary kiln, be connected through the flue between deposit room and the rotatory cylinder drier, be equipped with a plurality of flue gas tempering valves on the flue, be connected with the cooler between rotary kiln and the finished product bin, the flue surface is equipped with a packet cotton. The utility model discloses partial rotary kiln flue gas waste heat is utilized to the circulating connection mode of rotary kiln, deposit room and rotatory cylinder drier, with moisture desorption in the material and heating, prevents that the rapid inflation of raw materials inside moisture of material in the rotary kiln from making partial material broken, influence the quality of product and can prevent that moisture in the raw materials from evaporating in the rotary kiln and takes away a large amount of heats, waste fuel.
Description
Technical field
This utility model relates to rotary kiln technical field, the rotary kiln of a kind of band rotary drying drum.
Background technology
The moisture of rotary kiln charging at present is typically at 3-5%, and moisture drastically evaporates in rotary kiln, takes away amount of heat, the drastically expansion of material internal moisture simultaneously makes partial material crush, have impact on the distribution of particles of material, produce substantial amounts of coke breeze, part coke breeze is taken away with flue gas and is caused damage.Because of rotary kiln feeding belt water, so that the time of material dewatering preheating is longer, material shortened in the time of burning zone, and for ensureing calcined coke quality, general employing improves the measures such as calcining belt temperature, fuel quantity is made to increase, material is serious in burning zone scaling loss, and general rotary kiln scaling loss, about 15%, consumes combustion gas high, scaling loss is big, and the product quality produced is poor.
Summary of the invention
In order to solve tradition rotary kiln, to consume fuel high, and scaling loss is big, and the technical problem that the product quality produced is poor, this utility model provides the rotary kiln of a kind of band rotary drying drum.
A kind of rotary kiln of band rotary drying drum, including rotary kiln and finished product bin, it is characterized in that: also include expansion chamber and the rotary drying drum being connected with described rotary kiln, being connected by flue between described expansion chamber and described rotary drying drum, described flue is provided with some smoke regulating valves；Connect between described rotary kiln and described finished product bin and have cooler.
Described rotary kiln, is characterized in that: described flue outer surface is provided with bag cotton.
The beneficial effects of the utility model are:
1, the circulation connected mode of rotary kiln, expansion chamber and rotary drying drum is to utilize part rotary kiln fume afterheat, is removed by raw material moisture in rotary drying drum, prevents raw material drastically expansion of material internal moisture in rotary kiln from making partial material crush；The heating tape of material extends makes material homogeneous heating, and calcining fully, improves product density and intensity.
2, at system heating tape extended residence time and first it is dehydrated in rotary drying drum due to material, prevents the moisture in raw material from evaporating in rotary kiln and take away amount of heat, fuel used than current rotary kiln minimizing 10-15%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, each parts labelling is as follows: 1, rotary kiln, and 2, cooler, 3, finished product bin, 4, expansion chamber, 5, rotary drying drum, 6, flue, 7, smoke regulating valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in this utility model embodiment is clearly and completely described:
As shown in the figure, a kind of rotary kiln of band rotary drying drum, including rotary kiln 1, cooler 2, expansion chamber 4 and the rotary drying drum 5 connected with rotary kiln 1, flue 6 is had to connect between its middle setting chamber 4 and rotary drying drum 5, flue 6 is provided with the smoke regulating valve 7 of two regulation exhaust gas volumns, and cooler 2 is also associated with finished product bin 3.
The rotary kiln of this utility model a kind of band rotary drying drum is when producing, combustion gas enters rotary kiln 1 and heats whole system, the heat that rotary kiln 1 produces can enter into flue 6 by expansion chamber 4 and enter back in rotary drying drum 5, heats rotary drying drum 5；Wherein flue 6 outer surface is provided with bag cotton for being incubated.
Raw material enters into system from rotary drying drum 5, first with part rotary kiln fume afterheat in rotary drying drum 5, by the moisture removal in raw material and be heated to 400-500 DEG C, then material is made directly to heat in entering rotary kiln 1, the finished product produced in rotary kiln 1 cools down through cooler 2, enters finally in finished product bin 3.
The rotary kiln raw material of this utility model a kind of band rotary drying drum is dehydrated in rotary drying drum 5, first being prevented from raw material drastically expansion of material internal moisture in rotary kiln 1 makes partial material crush, affect the quality of product, next moisture being prevented from raw material evaporates in rotary kiln 1 takes away amount of heat, wastes fuel.
Claims (2)
1. the rotary kiln of a band rotary drying drum, including rotary kiln (1) and finished product bin (3), it is characterized in that: also include expansion chamber (4) and the rotary drying drum (5) being connected with described rotary kiln (1), being connected by flue (6) between described expansion chamber (4) and described rotary drying drum (5), described flue (6) is provided with some smoke regulating valves (7)；Connect between described rotary kiln (1) and described finished product bin (3) and have cooler (2).
Rotary kiln the most according to claim 1, is characterized in that: described flue (6) outer surface is provided with bag cotton.
