Abstract
The utility model relates to a multi-stage large capacity centrifugal blower for delivering the air and gas which is not corrosive and not self-inflammable and does not contains adhesive substances, in particular to a double-stage gas-making centrifugal blower. The utility model adopts a structure of single-suction, double-support and double-stage impellers, along with progressive power of all impellers, progressive improvement of pressure, meeting the requirements of the gas producer conditions in the nitrogenous fertilizer industry.
Description
Technical field
The utility model relates to a kind of multistage big flow centrifugal blower of carrying air and non-corrosiveness, not spontaneous combustion, not containing stickum gas, is specially adapted to use on the gas producer of nitrogenous fertilizer industry.
Background technique
In the nitrogenous fertilizer industry, need a kind of pressure height, gas making centrifugal blower that air quantity is big on the gas producer, general one-stage centrifugal blower can't reach its required pressure at all, and single-stage cantilever impeller less stable.
Summary of the invention
The purpose of this utility model is: a kind of new gas making centrifugal blower is provided, satisfies the needs of nitrogenous fertilizer industry gas producer operating mode.
The technical solution of the utility model is: this series blower adopts that single suction is gone into, the structural type of dual-supporting, both stage impellers.
Single suction is gone into scheme: design has an intake grill on half casing of a left side.
The dual-supporting scheme is: the design of half casing side has a bearing spider on a left side, constitutes double supporting structure with another bearing spider of the right side half casing side.
The both stage impellers scheme is: in a left side half casing and right half casing, two impeller serials are on same main shaft.Between two impellers, increased the sealing of dividing plate and dividing plate.
Owing to adopted the technical program, strengthened the stability of blower fan, increased air quantity, improved and boosted, satisfied the needs of nitrogenous fertilizer industry gas producer operating mode.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
In Fig. 1: 1, left half casing; 2, dividing plate; 3, impeller; 4, dividing plate seal arrangement; 5, main shaft; 6 bearing supports; 7, right half casing; 8, impeller; 9, coupling.
Embodiment
In Fig. 1, impeller (3) in a left side half casing (1), the impeller (8) in right half casing (7) drive work done by motor by coupling (9), main shaft (5), produce air quantity and blast, from impeller (3) to impeller (8) step by step to the gas work done, produce sufficiently high pressure and air quantity, satisfied the needs of nitrogenous fertilizer industry gas producer operating mode.
Claims (4)
