ANTI-NODULATION STRUCTURE OF FLOW GUIDE CAP OF SLEEVE KILN

摘要

Disclosed is an anti-nodulation structure of a flow guide cap of a sleeve kiln, comprising a lower inner sleeve (1) and a flow guide cap (2). The flow guide cap (2) is installed at the top part of the lower inner sleeve (1), the outer side of the flow guide cap (2) is provided with a refractory layer, the lower inner sleeve (1) has a cooling interlayer (3), the top part of the flow guide cap is provided with a sweeping assembly (4), the sweeping assembly (4) is embedded in the refractory layer and communicates with an inner cavity of the flow guide cap (2), an air guide assembly (5) is provided between the lower inner sleeve (1) and the flow guide cap (2), an air inlet of the air guide assembly (5) communicates with the cooling interlayer (3), an air outlet of the air guide assembly (5) is located in the inner cavity of the flow guide cap (2), a small part of cooling air in the lower inner sleeve (1) is introduced into the inner cavity of the flow guide cap (2) by means of the air guide assembly (5), the cooling air is then blown out from the sweeping assembly on the upper part of the flow guide cap (2) at a certain speed, and dust accumulation stuck at the position of the flow guide cap (2) is swept in real time, which can effectively alleviate or prevent the formation of nodules at the position of the flow guide cap.
