Description

Technical Field

[0001] The utility model relates to the technical field of sintering, in particular to a fuel matching device for a sintering machine. Background Art

[0002] Sintering machine is suitable for sintering operation in large-scale ferrous metallurgical sintering plants, and is mainly suitable for sintering of iron ore powder in large and medium-sized sintering plants. It is the main equipment in the exhaust sintering process, which can sinter concentrate powder and rich ore powder of different components and different particle sizes into blocks, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. Sintering machine is divided into several specifications of different lengths and widths according to the sintering area, and users can choose according to their output or site conditions. The larger the sintering area, the higher the output.

[0003] Sintering fuels include gas fuel, liquid fuel and solid fuel. The solid fuel used for sintering needs to be matched, proportioned and mixed during processing. When matching and proportioning, the staff weighs it, takes it out of the weighing equipment after weighing, and then adds it to the mixing equipment for mixing. The process of matching and proportioning solid fuel raw materials is cumbersome, which not only increases the workload of the staff, but also affects the processing efficiency of solid fuel. Utility Model Content

[0004] The utility model aims to provide a sintering machine fuel matching device, which has the advantages of simple and quick sintering fuel matching and proportioning process, can improve the processing efficiency of solid fuel, and solves the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sintering machine fuel matching device, comprising a mounting platform and a receiving hopper, wherein a first support seat and a second support seat which are symmetrically distributed are mounted at the lower end of the mounting platform, a rotating shaft is rotatably mounted at the upper end of the mounting platform, fixed rods which are distributed in an array are mounted on the rotating shaft, a support plate is mounted at the end of the fixed rod, a weighing sensor is arranged at the upper end of the support plate, a weighing box is arranged at the upper end of the weighing sensor, the receiving hopper is mounted at the side end of the second support seat, a feeding pipe is arranged at the side end of the receiving hopper, a feeding screw is rotatably mounted in the feeding pipe, and a discharge pipe is arranged at the upper position of the side end surface of the feeding pipe.

[0006] When using the sintering machine fuel matching device of the utility model,

[0007] When the solid fuel for sintering is matched and proportioned, one of the raw materials in the solid fuel is added to the weighing box, which can be weighed by the weighing sensor. After the weighing of one fuel raw material is completed, the rotating shaft is rotated by the first driving device, and the weighing box containing the fuel raw material is rotated to the top of the receiving hopper. The electromagnetic discharge valve on the first discharge pipe is opened, so that the weighed fuel raw material can enter the receiving hopper, and the fuel raw material in the receiving hopper can enter the feeding pipe through the second discharge pipe. The feeding screw can be rotated by the second driving device, which can drive the raw material in the feeding pipe to be fed, and finally discharged from the discharge pipe to the mixing equipment. After the weighing box is rotated, other raw materials of the solid fuel can continue to be weighed in other weighing boxes.

[0008] Preferably, the upper end surface of the mounting platform is provided with an annular limiting slide groove, and the lower end of the fixing rod is provided with a limiting slider, which is slidably installed in the limiting slide groove.

[0009] Preferably, a first driving device is provided at the lower end of the mounting platform, and a main shaft of the first driving device is connected to the axis of the rotating shaft.

[0010] Preferably, a first discharge pipe is installed at the lower position of the side end surface of the weighing box, and an electromagnetic discharge valve is provided on the first discharge pipe.

[0011] Preferably, a second feeding pipe is provided at the lower end of the receiving hopper, and the end of the second feeding pipe is connected to the feeding pipe.

[0012] Preferably, a second driving device is provided at the upper end of the feeding tube, and the main shaft of the second driving device is connected to the axis of the feeding screw.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: when mixing and proportioning solid fuel for sintering, the staff only needs to add the raw materials of the solid fuel into the weighing box for weighing. After the weighing is completed, the material can be automatically loaded, and other raw materials of the solid fuel can continue to be weighed while loading. The sintering fuel matching and proportioning process is simple and fast, and the material is automatically loaded, which can not only improve the processing efficiency of the solid fuel, but also reduce the work intensity of the staff.
