Abstract
The utility model relates to the field of centrifugal blowers, in particular to a centrifugal blower sealing nitrogen charge device. The Centrifugal blower sealing nitrogen charge device is characterized in that a sealing seat is sleeved on a spindle, a threaded hole is drilled in the outer portion of the sealing seat, an air guide ring is arranged between the threaded hole and sealing gas, and the threaded hole of the sealing seat is connected with a nitrogen charge connector. According to the technical scheme, the centrifugal blower sealing nitrogen charge device is simple to assemble, convenient to check and repair, high in nitrogen charge efficiency and reliable in performance.
Description
Technical field
The utility model relates to the centrifugal blower field, is a kind of sealing nitrogen charging device of centrifugal blower.
Background technique
At present, various centrifugal blowers on market at home on sealing configuration being all direct auger shell pit on sealing configuration, are installed and are filled the nitrogen joint, then connect source nitrogen, to be filled with nitrogen higher than the sealed inside gas pressure, realize that sealing fills the nitrogen function.Although blower fan sealing place air leakage is less at present, within industry standard.But for the growing market demand, for oxygen-enriched air, coal gas, SO
2The seal request of the special gas such as flue gas is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of through improved sealing nitrogen charging device.
The technical solution of the utility model is: it is characterized in that on main shaft that cover has sealing seat, be drilled with tapped hole in the sealing seat outside, install a guide ring between tapped hole and sealing gas additional, be connected on the tapped hole of sealing seat and fill the nitrogen joint.
Owing to having adopted technique scheme, blower fan sealing assembling is simple, and maintenance is convenient, fills nitrogen efficient higher, and performance is more reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, fill the nitrogen joint; 2, guide ring; 3, sealing seat; 4, main shaft.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In Fig. 1, on main shaft 4, cover has a sealing seat 3, is drilled with tapped hole in sealing seat 3 outsides, installs a guide ring 2 between tapped hole and sealing gas additional, is connected on the tapped hole of sealing seat 3 and fills nitrogen joint 1.
At the outside auger shell pit of sealing seat 3, install a guide ring 2 between tapped hole and sealing gas additional, this guide ring 2 is loop configuration, make by toroidal cavity that respectively to fill place, nitrogen hole inflated with nitrogen more even, the outer installation again of sealing seat 3 filled the nitrogen joint, then connect source nitrogen, to be filled with nitrogen higher than the sealed inside gas pressure, realize the function that nitrogen is filled in sealing.
