Abstract

The invention discloses a blast furnace tuyere structure. The blast furnace tuyere structure comprises an air pipe, an inner pipe, an outer pipe, a partition plate, a water inlet tank, a water outlet tank and a fixing device; the inner pipe is arranged on the outer side of the air pipe in a sleeving manner; the outer pipe is arranged on the radial outer side of the inner pipe, and one end of the inner pipe is connected with one end of the outer pipe; the partition plate is arranged between the inner pipe and the outer pipe; the water inlet tank comprises a first connector, and the first connector is arranged at the other end of the inner pipe; the water outlet tank comprises a second connector, and the second connector is arranged on one side of the first connector; and the fixing device is arranged between the inner pipe and the outer pipe, and the fixing device is used for fixing the partition plate. The end, close to the tuyere, of the partition plate is fixedly connected with the fixing device to fix the partition plate, the partition plate can be effectively prevented from gradually getting close to or making contact with the connecting portion of the inner pipe and the outer pipe in the working process, it is guaranteed that cooling water flowing in from the first connector can smoothly flow to the second connector from the tail end of the partition plate, and the cooling effect on the tuyere is guaranteed, and the service life of the blast furnace tuyere structure is prolonged.

Description

Technical field [0001] The present invention relates to a technical field Imperial Smelting furnace, particularly to a sealed structure blast furnace tuyeres. Background technique [0002] The related art, lead and zinc smelting process of the closed blast furnace, the wind mouth working in high temperatures over 900 degrees Celsius, the wind easily lead to mouth life is not long.
