Description

Technical Field

[0001] The invention relates to the technical field of sintering mixers, and in particular to a method for preventing a water adding pipe of a sintering mixing cylinder from sticking and preventing large pieces from coming out of the cylinder. Background Art

[0002] One of the processes for iron ore processing in steel enterprises is to use a sintering machine to process iron ore powder. During the sintering process, the overall sintering basicity of the raw materials needs to be adjusted to 1.9-2.0; the proportion of fine powder in the raw materials is about 20%, and the proportion of white ash is about 4.92%. After the raw materials are put into the sintering machine according to the proportion, they will be mixed by the mixer in it. During the mixing process of the raw materials, water needs to be added to moisten the raw materials and mix them evenly.

[0003] At present, the mixing cylinder and water-adding pipe of the sintering system are installed by wire rope hoisting. In the actual production process, the mixture adheres to the wire rope and the water-adding pipe body, and forms sticky blocks after a certain period of accumulation. When the wire rope and the water-adding pipe swing, the blocks fall off and fall into the mixture to form large blocks, which are easy to block the lower hopper and cause material spillage and overturning along the belt during the transportation of the mixture. At the same time, the mixing silo at the sintering machine head is easy to cause the round roller to get stuck, affecting the distribution of materials in front of the furnace and causing fluctuations in the sintering process. Summary of the invention

[0004] The purpose of the present invention is to provide a method for preventing the sintering mixing cylinder water adding pipe from sticking and the cylinder from forming large lumps, so as to solve the technical problem in the prior art that the mixed material adheres to the steel wire rope and the water adding pipe body and forms sticky lumps after a certain period of accumulation.

[0009] Step 3: The powder adhered to the water supply pipe can be flushed through the nozzle mechanism on the upward inclined diversion pipe. The serrated iron sheet on the water supply pipe can effectively prevent the powder from sticking into blocks. At the same time, the serrated iron sheet can guide the water flow to facilitate flushing of the powder adhered to the top of the water supply pipe.
