Description

Technical Field

[0001] The utility model relates to the technical field of cement processing devices, in particular to a kiln tail bypass venting device for cement processing. Background Art

[0002] Cement is made through two grindings and one burning. That is, the raw materials are mined, crushed, ground and mixed to make raw meal. The raw meal is burned at high temperature to make clinker, and the clinker is crushed and ground with gypsum or other mixed materials to make cement.

[0003] During the cement processing process, it needs to be calcined at a high temperature in a cement kiln to form it. Because the kiln will accumulate heat after heating, the hot air inside the cave will not be easily lost, and the cement can be processed efficiently. At the same time, due to the accumulation of heat, the air inside the cave is easily changed to produce toxic gases. It is generally said that a bypass venting device at the end of the kiln is used to circulate the internal air in a timely manner to ensure the health of the staff. However, the existing venting devices generally ventilate the cave through one or more fans operating at the same time. This venting placement requires multiple power devices to supply energy to multiple fans separately, which will lead to a waste of power resources. At the same time, when multiple power devices are running, the surrounding temperature will also rise, which is not conducive to the use efficiency of the device.

[0004] Therefore, we provide a kiln tail bypass venting device for cement processing. Utility Model Content

A second rotating fan 7 is fixedly connected to one side of the rotating connecting tube 6. When the device needs to ventilate, the staff turns on the rotating motor 1 to make it operate. The operation of the rotating motor 1 will drive the rotating gear 2 to rotate, and the rotation of the rotating gear 2 will drive the passive gear 3 to rotate at the same time, so that the threaded bolt 4 can drive the first rotating fan 5 to rotate, and the rotation of the threaded bolt 4 can drive the rotating connecting tube 6 to rotate, and the rotation of the rotating connecting tube 6 makes the second rotating fan 7 rotate at the same time, so as to achieve the effect of the first rotating fan 5 and the second rotating fan 7 rotating at the same time, thereby improving the ventilation efficiency of the device.

[0026] like Figure 1-Figure 4 As shown, a threaded rod 8 is provided on one side of the threaded bolt 4, and connecting rods 9 are fixedly connected on both sides of the threaded rod 8. The connecting rod 9 is connected to a rotating belt 11 through a pulley 10. The pulley 10 and the moved belt 11 are belt-driven, and the connecting rod 9 is fixedly connected to the pulley 10. The rotating belt 11 and the rotating connecting cylinder 6 are belt-driven, and the rotating connecting cylinder 6 is connected to two rotating belts 11 at the same time. When the device moves, the rotation of the threaded bolt 4 will drive the threaded track on the surface to rotate at the same time. The threaded bolt 4 is opposite to the threaded track on the threaded rod 8, so that the rotation of the threaded bolt 4 can drive the threaded rod 8 to rotate at the same time, and the rotation of the threaded rod 8 can drive the pulleys 10 on both sides to rotate at the same time. By connecting the pulley 10 and the rotating connecting cylinder 6 with the rotating belt 11, the rotating connecting cylinder 6 and the connecting rod 9 can be rotated at the same time, thereby achieving the effect of rotating the entire device through the rotation of the threaded bolt 4.
