Abstract
The utility model relates to a multistage high-speed oxygen-supercharging blower for steel plate welding. According to the technical scheme, a left baring box set and a right bearing box set are locked on a steel plate welding case through bolts, four partitions are disposed in the steel plate welding case, four impellers are serially disposed on a spindle, the spindle is suspended in the steel plate welding case, and two ends of the spindle respectively penetrate through the steel plate welding case and are rested on the left bearing box set and the right bearing box set. A return gas pipe set and two carbon ring seals are disposed at the parts of the steel plate welding case, penetrated by the spindle. The four impellers on the spindle are driven by a driver to rotate at high speed in the steel plate welding case so as to achieve oxygen supercharging. The multistage high-speed oxygen-supercharging blower for steel plate welding has the advantages of short production cycle, low manufacturing cost, compact structure and the like.
Description
Technical field
The utility model belongs to blower fan and metallurgical technology field, is specially adapted to metallurgy industry and uses.
Background technique
Along with national energy-saving reduces discharging the continuous propelling of policy and improving constantly of each large steel mill output, the use amount of oxygen blower fan also constantly increases, and common multistage high-speed fan is by the cast iron manufacturing, and the manufacture cycle is long, and manufacture cost is too high.
The model utility content
The utility model is intended to overcome above-mentioned technological deficiency, and purpose provides the multistage high speed oxygen of a kind of Plate Welding booster fan.
The technical solution adopted in the utility model is: be comprised of Plate Welding casing, left bearing case group, bolt, carbon ring seal body, impeller, main shaft, dividing plate, muffler group, right bearing case group.
The utility model is locked in left bearing case group and right bearing case group on the Plate Welding casing with bolt, four dividing plates are installed in the Plate Welding casing, four impeller serials are installed on the main shaft, main shaft is lifted in the Plate Welding casing, the Plate Welding casing is passed respectively at the two ends of main shaft, drops on left bearing case group and the right bearing case group.Muffler group and two carbon ring seal bodies are installed in the through part of main shaft and Plate Welding casing, prevent oxygen leakage.By four impellers High Rotation Speed in the Plate Welding casing on the driving machine drive main shaft, realize the oxygen supercharging, owing to adopt the Plate Welding casing, its manufacture cycle shortens, manufacture cost reduces greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In the drawings: 1, bolt; 2, left bearing case group; 3, carbon ring seal body; 4, Plate Welding casing; 5, impeller; 6, main shaft; 7, dividing plate; 8, muffler group; 9, right bearing case group.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further explanation.
The multistage high speed oxygen of a kind of Plate Welding booster fan is comprised of Plate Welding casing (4), left bearing case group (2), bolt (1), carbon ring seal body (3), impeller (5), main shaft (6), dividing plate (7), muffler group (8), right bearing case group (9).Owing to bolt (1) left bearing case group (2) and right bearing case group (9) are locked on the Plate Welding casing (4), four dividing plates (7) are installed in the Plate Welding casing (4), four impellers (5) are installed in series on main shaft (6), main shaft (6) is lifted in the Plate Welding casing (4), the two ends of main shaft (6) penetrate respectively Plate Welding casing (4), drop on left bearing case group (2) and the right bearing case group (9) its compactness rational in infrastructure.Owing to adopt the Plate Welding casing, its manufacture cycle shortens simultaneously, and manufacture cost reduces greatly.
Because muffler group (8) and two carbon ring seal bodies (3) are installed in the through part of main shaft (6) and Plate Welding casing (4), well prevent oxygen leakage.By four impellers (5) High Rotation Speed in Plate Welding casing (4) on the driving machine drive main shaft (6), realize the oxygen supercharging.
Therefore, the multistage high speed oxygen of this Plate Welding booster fan has the characteristics such as with short production cycle, low cost of manufacture, compact structure.
