[0002] When the cement kiln is calcining cement clinker, a high-temperature fan is used to heat the kiln. The high-temperature fan is connected to the pipeline system, through which the air is transported and the air volume and speed are controlled and adjusted. The pipeline cooperates with the diversion regulating air valve and baffle to control the air volume and speed.
[0003] During the use of existing high-temperature fan ducts, the transition when the duct diameter changes is not natural enough, and the right-angle elbow duct used causes the wind resistance inside the duct to increase, affecting the wind speed and increasing the resistance loss.
[0004] Therefore, those skilled in the art provide a gradually expanding and variable diameter resistance-reducing kiln system outlet pipe structure to solve the problems raised in the above background technology. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A gradually expanding and variable diameter resistance-reducing kiln system outlet pipe structure comprises: a bent pipe, an interface ring is sleeved on the upper end of the bent pipe, and an expanding pipe is installed on one side of the interface ring, an end of the expanding pipe away from the bent pipe is integrally connected with a pipe opening, a docking piece is fixedly provided on the surface of the expanding pipe, and a connecting piece is fixedly provided on the surface of the docking piece, a hanging ring is movably connected inside the connecting piece, a fixed sleeve ring is installed on one side of the interface ring, and a hook is movably connected on the surface of the fixed sleeve ring.
[0008] As a further solution of the present invention, pin holes are arranged at four corners of the surface of the interface ring, and pins corresponding to the pin holes are arranged at four corners of the inner wall of the docking piece.
[0009] As a further solution of the present invention, the diameter-expanding pipe and the curved pipe are connected in a chimeric manner, and the diameter of the diameter-expanding pipe is larger than the diameter of the curved pipe.
[0010] As a further solution of the utility model, a docking flange for pipeline connection is installed at the lower end of the elbow.
[0011] As a further solution of the present invention, the hanging rings are distributed in a ring shape with respect to the symmetrical center line of the docking piece, and the hanging rings and the hooks are arranged in a one-to-one correspondence.
[0012] As a further solution of the present invention, the fixing collar and the elbow are fixedly connected.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. Set up a full-arc elbow to reduce the local resistance of the air duct and prevent eddy currents and noise in the air duct. The inner wall of the full-arc elbow is smooth and the transition is smooth, thereby reducing resistance at the turn and reducing resistance damage.
[0015] 2. The diameter of the expanded pipe is set to be larger than the diameter of the bent pipe. A gradual expansion and diameter change is adopted between the expanded pipe and the bent pipe, so that the change in pipe diameter gradually increases, the smoothness of the pipe is increased, the resistance loss is reduced, and the air volume, velocity and flow are better coordinated, thereby maintaining the stable operation of the fan and preventing stalling.
