Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
The utility model relates to a grit material cylinder drying device, as shown in figure 1, including drying drum 1, feed arrangement 2, drive arrangement 3, combustor 4 and cold wind passageway 5. The axial both ends of drying drum 1 are feed end 11 and discharge end 12 respectively, and feed inlet 111 has been seted up to the feed end, and discharge end 12 is equipped with discharge gate 121. The material that drive arrangement 3 drive drying drum 1 is rotatory to make in drying drum 1 is moved to discharge end 12 by feed end 11, and feed arrangement 2 corresponds through the feeding end seat and installs in feed end 11, and combustor 4 corresponds through the discharge end seat and installs in discharge end 12, and cold wind passageway 5 sets up in all side positions of combustor 4, and cold wind passageway 5 is located drying drum 1's discharge end 12. The cold air passage 5 communicates with the drying drum 1, and the cold air passage 5 communicates with the outside air.
The feed end 11 of the drying roller 1 is provided with a flue gas outlet 13, the flue gas outlet 13 is connected with a flue 6, and the flue 6 is provided with an induced draft fan 7 for introducing outside air into the drying roller 1.
When the sand and stone material roller drying device is used, sand and stone materials are transmitted by the feeding device 2 and transferred to the inside of the drying roller 1 through the feeding end 11, the burner 1 is arranged at the discharging end 12 opposite to the feeding end 11, and hot flue gas generated by the burner 4 and the sand and stone materials perform countercurrent heat exchange in the drying roller 1, so that moisture in the sand and stone materials is removed. The sand material after heat exchange (i.e. after moisture removal) is discharged from the discharge port 121. And the waste gas generated after the heat exchange of the flue gas is discharged from the flue gas outlet 13 through the flue 6.
After the technical scheme is adopted, the utility model discloses an grit material cylinder drying device lets in partly cold wind (introducing the ambient air by draught fan 7) at discharge end 12 at combustor 4 place to reduce the hot flue gas temperature that combustor 4 produced, make hot flue gas total amount obtain great promotion again, thereby a large amount of hot flue gas of low temperature avoid grit material high temperature with grit material heat transfer in-process, make the exhaust gas temperature who produces after the heat transfer lower again, thereby very big reduction the energy consumption of drying.
As a preferred embodiment, the connecting section of the flue 6 to the flue gas outlet 13 is provided with an auxiliary burner 14. The connecting section of the flue 6 and the flue gas outlet 13 is also provided with a temperature measuring element 15, and the flue gas outlet 13, the auxiliary burner 14 and the temperature measuring element 15 are arranged in sequence.
The flame that combustor 4 produced and the waste gas behind the grit material heat transfer discharge from the feeding end seat, in order to avoid the temperature to hang down excessively, set up supplementary combustor 14 on the feeding end seat, when the exhaust gas temperature that temperature measuring element 15 detected was crossed lowly, open supplementary combustor 14 and improve exhaust gas temperature to avoid waste gas humidity to hang down excessively (the flue gas temperature crosses lowly can take place the dewfall), avoid causing harmful effects to follow-up equipment.
The above embodiments and drawings do not limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be considered as departing from the scope of the present invention.
