[0053] The second aspect of the present application provides a ring cooler production line for a sintering pelletizing plant to reduce dust during the unloading process of the ring cooler.
[0054] The ring cooler production line of a sintering pelletizing plant provided in the embodiment of the present application includes a sintering machine and a ring cooler arranged in sequence according to the process.
[0055] The unloading process of the ring cooler of the present application and the ring cooler production line of the sintering pelletizing plant is described in detail below:
[0056] Before the annular cooler discharges ash, the control device controls the connecting piece 410 to move back and forth along the track to reach the position of the duct 200, connecting the duct 200 and the dust removal piece, and the dust removal piece is connected to the suction device. Since one end of the duct 200 is connected to the upper cover 110 of the annular cooler belt conveyor and the other end is connected to the dust removal piece, the dust removal piece is connected to the suction device, and the double-layer unloading valve 500 is connected to the upper cover 110 of the annular cooler belt conveyor. After the double-layer unloading valve 500 is opened, the bulk material enters the upper cover 110 of the annular cooler belt conveyor from the annular cooler and falls into the annular belt conveyor 120 in the upper cover 110 of the annular cooler belt conveyor, and is transported by the annular belt conveyor 120. During the ash discharge process, the dust can be sucked out by the suction action of the suction device to reduce the dust problem during the ash discharge process. When the ash discharge at this point is completed, the control device controls the connecting piece 410 to move back and forth along the track to reach the next duct 200 position to discharge ash at the next point.
[0057] The ring cooler and the ring cooler production line of the sintering pelletizing plant of the present application have at least the following advantages:
[0058] (1) The present application is provided with a bulk material collection unit connected to the main body of the ring cooler. The bulk material of the ring cooler enters the upper cover of the ring cooler belt conveyor of the bulk material collection unit, and then the ring belt conveyor transports the bulk material of the ring cooler to achieve the dust removal effect of the ring cooler. At the same time, a duct connected to the bulk material collection unit is provided. The duct and the dust extraction unit are connected through a connecting unit. When the suction device of the dust extraction unit is working, the bulk material in the dust extraction member is sucked. Since the dust extraction member is connected to the duct through the connecting member, and the duct is connected to the upper cover of the ring cooler belt conveyor, the dust in the upper cover of the ring cooler belt conveyor can pass through the duct into the connecting member, and then pass through the connecting member into the dust extraction member, and be extracted by the suction device. Compared with the prior art, the present application can achieve the technical problem of controlling the large amount of dust in the unloading process of the ring cooler.
[0059] (2) The present application has multiple ducts, which are spaced apart along the extension direction of the upper cover of the ring cooling belt conveyor to provide multiple dust extraction points. Dust extraction operations are performed at each point separately to prevent excessive dust from being generated when multiple points are removed at the same time.
