In order to achieve the above purpose, the utility model adopts the following technical scheme:
a grating net for filtering the big solid dregs blocks of metallurgical dregs and the inlet structure of heat exchanger are composed of a hopper fixed to the top of heat exchanger, the stocker is internally provided with a cavity, the top end of the cavity is provided with a plurality of first baffle plates which are staggered with each other, the first partition plates are sequentially arranged in a descending manner from left to right in height, a diversion trench is formed between every two adjacent first partition plates, the diversion trenches are mutually communicated, and the top end of the heat exchanger is provided with an inlet which is communicated with the diversion trench, the top end of the diversion trench is provided with a rotating rod, two ends of the rotating rod are rotatably connected to the side wall of the material storage device, a plurality of shifting plates are symmetrically and fixedly arranged on the side wall of the rotating rod, the shifting plate is arranged above the opening at the top end of the diversion trench, a feeding pipe is fixedly arranged on the side wall of one side of the material storage device, and a slag removal port is arranged on the upper side wall of one end, far away from the feeding pipe, of the material storage device.
Preferably, the side walls of the hopper at both sides of the partition are inclined gradually toward the middle.
Preferably, the inner part of the sidewall of the hopper is a hollow structure.
Preferably, a filter plate is clamped in the slag removing port.
Preferably, the stocker, the first partition plate, the rotating rod, the shifting plate and the feeding pipe are all made of tungsten steel materials.
The utility model has the advantages that: the guiding gutter that forms between a plurality of baffles of utilization that can be fine is different from traditional grid net, with the help of dialling the rotation of board, improves the mobility of molten steel, prevents that the slag in the molten steel from piling up the entrance at the guiding gutter to this realization is to the slag in the molten steel effectively separate, has also directly promoted the efficiency that the molten steel entered into in the heat exchanger, and overall structure is simple, and the practicality is very strong.
