Description

Technical Field

[0001] The utility model relates to the technical field of sintering machines, and in particular to a sintering machine with a waste heat recovery and utilization function. Background Art

[0002] The sintering machine is the main equipment in the exhaust sintering process. It can sinter concentrate powder and rich ore powder of different components and particle sizes into blocks, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. It is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants, mainly suitable for the sintering treatment of iron ore powder in large and medium-sized sintering plants.

[0003] The sintering machine is not a machine, but a project composed of several processes. During the use of the sintering machine, the raw materials will be ignited when passing through the sintering chamber, and under the action of negative pressure exhaust, they will burn downward while moving forward. When the raw materials come out of the sintering chamber, the burned raw materials still carry some residual heat, thereby heating the surrounding air and increasing the surrounding temperature. The existing sintering machines cannot utilize this part of the residual heat, which not only causes a waste of resources, but also makes the working environment of the operator hotter and increases the difficulty of the operator's work. Therefore, improvements are needed. Utility Model Content

[0043] When the threaded rod 10 rotates, the cross bar 12 threadedly sleeved on the outer surface of the threaded rod 10 will move along the inner surface of the support plate 13, thereby driving the top end of the movable rod 14 to move together.

[0044] Among them, the bottom end of the movable rod 14 is hinged with a lifting plate 15, the right end of the lifting plate 15 is movably connected to the left end of the sintering box 7, the bottom of the inner surface of the front and rear ends of the lifting plate 15 are movably sleeved with a limit block 16, and the right end of the limit block 16 is fixedly connected to the left end of the sintering box 7.

[0045] When the top end of the movable rod 14 moves, since the movable rod 14 and the lifting plate 15 are hinged, the lifting plate 15 will move downward along the outer surface of the limiting block 16 under the action of the movable rod 14 .

[0046] Among them, a power motor 17 is fixedly installed on the right side of the bottom end of the bracket 1, and the other end of the output shaft of the power motor 17 is fixedly sleeved with a power shaft 18.

[0050] The working principle and use process of this utility model:

[0051] First, the operator starts the power motor 17, so that the power shaft 18 drives the driving wheel 19 to rotate. Since the driving wheel 19 is connected to the driven wheel 21 through the material conveyor belt 22, the material conveyor belt 22 will rotate, thereby conveying the raw materials. When the raw materials enter the sintering box 7, they will be heated and burned. When the burned raw materials are output from the inside of the sintering box 7 and enter the first partition box 2, the operator starts the fan 503, so that the hot air inside the first partition box 2 enters the fan 503 after being filtered by the filter plate 502, and then enters the heating box 506 through the air outlet pipe 505. , and finally after being heated by the heating box 506, it enters the interior of the second partition box 3 through the exhaust pipe 507, thereby preheating the raw materials located inside the second partition box 3.

With the mutual cooperation of various mechanisms, the recovery and utilization of the waste heat of the sintering machine is realized.

[0052] During the operation of the sintering machine, the operator starts the driving motor 9 to rotate the threaded rod 10. Since the outer surface of the threaded rod 10 and the inner surface of the cross bar 12 are threadedly connected, as the threaded rod 10 rotates, the cross bar 12 will move the top of the movable rod 14 along the inner surface of the support plate 13, so that the bottom end of the movable rod 14 generates a thrust on the lifting plate 15, pushing the lifting plate 15 to move downward along the outer surface of the limit block 16. The operator can control the opening of the left and right ends of the sintering box 7 by adjusting the position of the lifting plate 15, thereby reducing the loss of heat inside the sintering box 7.
