Technical Field
[0001] The utility model belongs to the technical field of electric furnace accessories, in particular to a gradient smoke exhaust water cooling material trough structure. Background Art
[0002] Electric furnace is one of the most common heating equipment in industrial manufacturing. Electric furnace needs to input fuel when working. There will be a certain amount of flue gas during the combustion process of fuel. This part of flue gas needs to be purified before it can be naturally discharged. The flue gas not only contains more harmful substances, but also has extremely high temperature. While purifying the harmful substances in the flue gas, the flue gas also needs to be cooled to avoid the flue gas from having adverse effects on the surrounding gas environment due to high temperature.
[0003] A Chinese patent application (or patent) with announcement number CN215002963U discloses an improved water-cooled material trough for an electric furnace, comprising a cold water tank, a water-cooled trough with an open top embedded on the top of the cold water tank, a water inlet pipe installed on the bottom of the cold water tank, a water outlet pipe installed on one side of the cold water tank, the water outlet pipe is located above the water inlet pipe, driving plates are provided on both sides of the cold water tank, a vertical rod is slidably installed on one side of the driving plate, a cover plate is provided on the top of the water-cooled trough, the top of the vertical rod is fixedly connected to the cover plate, a horizontally arranged cross plate is slidably installed in the water-cooled trough, and a connecting rod is provided between the cross plate and the cover plate; the utility model realizes water cooling and cooling of materials by combining water cooling and air cooling, and at the same time, large-scale blowing and exhaust accelerate air flow, greatly improves the cooling efficiency of the cold water tank, and is easy to promote.
[0004] The above-mentioned improved electric furnace water-cooling trough is provided with a water-cooling structure and an air-cooling mechanism.

Example 2
[0032] See also Figure 3-4 On the basis of Example 1, a water-cooling pipe 3 is further provided, in which a plurality of smoke exhaust holes 303 are provided. The cooperation of the smoke exhaust holes 303 and the hole-blocking plate 401d can realize a stepped smoke exhaust effect, and a water-cooling component 4 is further installed on the water-cooling pipe 3, by which the cooling effect of the smoke in the water-cooling pipe 3 can be improved.

The stirring rod 402a rotates in the track groove, and when the stirring rod 402a rotates along the track groove on the lower track 402d, the blade plate 402c on the outer wall stirs the coolant stored in the cooling groove 302, so that the coolant can circulate and contact with the inner wall of the water-cooling tube 3, thereby improving the cooling efficiency. Utilizing the principle of hot air rising, the height positions of flue gases at different temperatures are also different.
