Abstract
The utility model discloses a modified rotary kiln hood cooling device, including kiln hood structure cooling fan and the cold one section fan of ring, kiln hood structure cooling fan is connecting the kiln hood shell ring that carries out the air feed to the rotary kiln hood through the cooling tube, and the cold one section fan of ring is setting up main, vice two play tuber pipes, main play tuber pipe with the cooling tube be linked together, vice going out install a slide valve on the tuber pipe, vice air outlet that goes out the tuber pipe pass through the pipeline with kiln hood shell ring be linked together. The utility model discloses a tractor serves two purposes can provide sufficient cooling amount of wind, guarantee cooling effect.
Description
Technical Field
The utility model relates to a modified rotary kiln hood cooling device.
Background
The kiln head iron protector of the rotary kiln is an important protection device for the rotary kiln cylinder section, the temperature of the kiln head is high, the kiln head is washed by high-temperature materials for a long time, the kiln head iron protector bolt is burnt, the iron protector falls, and the rotary kiln cylinder section can deform and crack. The internal high temperature can be achieved by the process requirements, and the external strong refrigeration is also indispensable. The cooling fan with the two-line kiln head structure provides an external cooling air source for the kiln head, and the fan flow rate is 15614 and 20237m 3/h. At present, the cooling air volume is insufficient.
Disclosure of Invention
An object of the utility model is to provide a modified rotary kiln hood cooling device can provide sufficient cooling amount of wind, the guarantee cooling effect.
The utility model aims at realizing like this, a modified rotary kiln hood cooling device, including kiln hood structure cooling fan and the cold one section fan of ring, kiln hood structure cooling fan is connecting the kiln hood shell ring that supplies air to the rotary kiln hood through the cooling tube, and the cold one section fan of ring is setting up main, vice two play tuber pipes, main play tuber pipe with the cooling tube be linked together, is installing a slide valve on the vice tuber pipe, vice air outlet who goes out the tuber pipe pass through the pipeline with kiln hood shell ring be linked together.
The flow rate of a cooling fan at the ring cooling section 75675 and 81496m3/h, the full pressure 5971 and 5696Pa, the rotating speed of the fan 960rpmn, and the opening degree of the air valve at the ring cooling section is 3-5% when the fan is normally produced, which means that 95% of the air volume is idle. A section of pipeline is led out from an outlet of an annular air pipe and upwards connected to a cooling air pipe of a fan of an original structure, and a gate valve is installed and used for adjusting air volume. The opening degree of the gate valve meets the requirement of the air quantity of the ring cooling section, and the opening degree of the air door of the ring cooling section fan is utilized to adjust the cooling air quantity of the kiln hood. The cooling device has two purposes, can provide enough cooling air quantity, and guarantees the cooling effect.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the connection structure of the present invention.
Detailed Description
The utility model provides a modified rotary kiln hood cooling device, as shown in figure 1, including kiln hood structure cooling fan 5 and ring cold one section fan 1, kiln hood structure cooling fan 5 is being connected through cooling tube 6 and is carrying out the kiln hood shell ring 3 that supplies the wind to the rotary kiln hood, and ring cold one section fan 1 is setting up main, two vice play tuber pipes, main play tuber pipe 2 with cooling tube 6 communicate mutually, is installing a slide valve 7 on the vice tuber pipe, the air outlet 4 of vice tuber pipe through the pipeline with kiln hood shell ring 3 be linked together.
