[0002] The mud roller distributor is the main supporting equipment of the sintering machine in modern steel plants. The mud roller distributor is installed on the frame of the sintering machine head. Its function in the sintering production process is to distribute the mixed sintering raw materials evenly, continuously and regularly on the sintering machine trolley. The width of the mud roller of the mud roller distributor is equal to the width of the sintering machine trolley. When the mud roller rotates, the speed of each point on it is the same, so it can achieve uniform feeding across the width of the sintering machine. Whether the distribution on the sintering machine trolley is uniform directly affects the output and quality of sintered ore. The main structure of the mud roller distributor includes mud roller, transmission device, and cleaning device. The outer lining of the mud roller is a stainless steel plate to facilitate the removal of sticky materials. A cleaning device is set in the opposite direction of the mud roller discharge side. The distributor is driven by a speed regulating motor, and the amount of feeding is controlled by the mud roller speed and the gate.

[0003] During the production process, the ribs on both sides of the mud roller of the mud roller distributor are very easy to stick to the material. If the sticky material is not cleaned in time, it will seriously affect the material distribution on both sides of the sintering machine trolley. At present, major domestic steel mills generally adopt measures such as manual regular cleaning, spring tension sweeper cleaning, or removal of the baffles on both sides of the mud roller to eliminate sticky materials. However, from the perspective of use, these methods have significant defects: manual cleaning requires additional jobs and increases the labor intensity of workers; spring tension sweepers are prone to failure and cannot be cleaned thoroughly; after the ribs on both sides of the mud roller are removed, the material spills seriously. Therefore, the current cleaning effect of mud roller sticking is not satisfactory, and it is very necessary to take technical measures to effectively solve the problem of sticking on both sides of the mud roller.
