Description
TECHNICAL FIELD
[0001] The utility model relates to a sintering machine trolley baffle strip synchronous cleaning device belongs to metallurgical industry sintering machine trolley baffle strip cleaning device technical field. BACKGROUND
[0002] When the sintering material temperature is too low, especially below the dew point, the lower layer of mixed material is prone to be too wet, which affects its permeability during the sintering process; and when a large proportion of brown iron ore is sintered, in order to ensure the balling effect, the moisture of the mixed material required during the sintering process is relatively high, which also increases the opportunity of sintering machine trolley baffle strip sticking.
[0003] The influence of the materials in the mixed material on the sintering process mainly has two aspects: one is iron ore powder, which usually encounters mineral powder such as Indian powder in production, the AL2O3 content of this kind of material is high, the liquid phase viscosity generated during the sintering process is relatively large, and it is easy to accumulate in the baffle strip gap during the sintering process, forming a hard shell such as an oxidation layer, which leads to sticky baffle strip after accumulation day by day; the other situation is that the fuel particle size is too large, and the liquid phase generated during the sintering process is sufficient and sticks to the baffle strip.
[0004] Adding a bottom layer of material during the sintering process is an important process link of sintering production. Before the mixed material is distributed to the sintering trolley, a layer of bottom layer of material is first laid on the bottom of the trolley, which has many benefits for sintering production, mainly manifested as that the bottom layer of material can reduce the burning loss of the sintering machine trolley beam and trolley baffle strip caused by continuous high temperature, reduce the wear and tear of the fan impeller caused by the dust particles in the sintering process entering the exhaust system, and the bottom layer of material can maintain and improve the effective exhaust area of the sintering machine. However, improper or non-standard use of the bottom layer of material can also cause the problem of sintering machine trolley baffle strip sticking. When the particle size of the bottom layer of material is too small, such as 6~14mm selected by some sintering machines, the small particles of the bottom layer of material are easy to block in the baffle strip gap, causing the baffle strip to be blocked, and the small particles of the bottom layer of material also deteriorate the permeability of the bottom layer of material itself. When the particle size of the bottom layer of material is relatively large and the thickness of the bottom layer of material is not guaranteed, the gap between the bottom layer of material is large, and the sintering material will directly contact the sintering machine trolley baffle strip, causing the trolley baffle strip to stick. When the thickness of the bottom layer of material is below 20mm, the sintering material particles are easy to penetrate the bottom layer of material and seep into the baffle strip gap of the sintering trolley, causing the trolley baffle strip to be sticky.
