Problems solved by technology

[0002] The part connected between the kiln tail smoke chamber of cement rotary kiln and the bottom of the calciner is usually a contraction part. In order to control the ventilation in the kiln, a horizontal in-line raft is often installed in the contraction part to adjust the ventilation in the kiln. Because the kiln air contains The amount of dust is large, and it is easy to accumulate dust on the raft. The high-temperature melting of dust will cause the switch of the raft to be stuck. Sealing, a large amount of leakage of ambient cold air will cause skinning, heat consumption, coal consumption, and system power consumption to increase

Embodiment Construction

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.

[0021] With the device for adjusting the flue flow area of ​​the present invention, the flue flow area at the shrinkage portion of the smoke chamber should be adjusted at the constriction pipe body connected to the bottom of the cement rotary kiln kiln tail smoke chamber 7 and the calciner 8 . A raft assembly that can rotate to change the flow area is installed in the pipe body of the necking part.

[0022] The valve plate assembly includ...

Abstract

The invention provides a device capable of adjusting the flue flow area. According to the device, action of raft pieces is not prone to being interfered by smoke dust, the device comprises a pipelinebody capable of guiding smoke, a raft assembly capable of rotating to change the flow area is installed in the pipeline body, and the raft assembly comprises at least one raft unit. Each raft unit comprises a raft piece and a rotating shaft, the rotating shafts are rotationally connected to the side wall of the pipeline body, and the raft pieces are fixedly connected to the rotating shafts.

Description

technical field [0001] The invention relates to the technical equipment field of a cement production line, in particular to a device for adjusting the flow area of ​​a flue. Background technique [0002] The part connected between the kiln tail smoke chamber of cement rotary kiln and the bottom of the calciner is usually a contraction part. In order to control the ventilation in the kiln, a horizontal in-line raft is often installed in the contraction part to adjust the ventilation in the kiln. Because the kiln air contains The amount of dust is large, and it is easy to accumulate dust on the raft. The high-temperature melting of dust will cause the switch of the raft to be stuck. Sealing, a large amount of leakage of ambient cold air will cause skinning, heat consumption, coal consumption, and system power consumption will increase. Contents of the invention [0003] The problem to be solved by the present invention is to provide a device for adjusting the flow area of ​...
