Abstract
The invention relates to the field of centrifugal blowers, in particular to a mass-flow oxygen production three-dimensional flow centrifugal blower which is composed of a left machine shell, a main shaft, a left sliding bearing, a right sliding bearing and a right machine shell. The mass-flow oxygen production three-dimensional flow centrifugal blower is characterized in that the left machine shell and the right machine shell are integrally connected, a volute chamber is arranged on the right machine shell, a front backflow machine and a rear backflow machine are placed in the left machine shell and the right machine shell which are integrally connected, the left sliding bearing and the right sliding bearing are respectively placed in the left machine shell and the right machine shell, a front vane wheel, a middle vane wheel and a back vane wheel are arranged on a main shaft in a sleeved mode, and the vane shapes of the front vane wheel, the middle vane wheel and the back vane wheel are in irregular curved surface shapes. Due to the adoption of the technical scheme, the structure is compact, the efficiency is high, the power consumption is saved, and the cost is reduced.
Description
Technical field
The present invention relates to the centrifugal blower field, is a kind of large flow oxygen three-dimensional flow centrifugal blower.
Background technique
In large-scale oxygenation project, because oxygen making amount is large, therefore the air quantity that requires centrifugal blower to provide is large, while is due to the needs of oxygen technological process, the air that requires blower to provide boosts and wants high, reach 200Kpa, the big-flow high-pressure centrifugal blower, the merit that consumes is very large, present large flow oxygen centrifugal blower, and its efficient is between 82-83%, a large flow boosts and is the oxygen centrifugal blower of 200Kpa, wasted work is more than 6640KW, and 24 hours every days are operation continuously, and the annual electric energy that consumes is very big.
Summary of the invention
The objective of the invention is to provide that a kind of efficient is high, the big-flow high-pressure power oxygen centrifugal blower of power consumptive province.
Technological scheme of the present invention is: be comprised of left casing, main shaft, left sliding bearing, right sliding bearing, right casing, it is characterized in that left casing is connected with right casing, volute chamber is on right casing, front return channel and rear return channel are put into the left casing that is connected, right casing, left sliding bearing, right sliding bearing are placed into respectively in left casing and right casing, and front impeller, middle impeller, rear impeller set are on main shaft; The blade shape of front impeller, middle impeller, rear impeller is not irregular curve form.
Owing to having adopted technique scheme, compact structure, efficient is high, the power consumptive province, has saved the energy, has reduced cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
In the drawings: 1, left casing; 2, main shaft; 3, left sliding bearing; 4, front impeller; 5, front return channel; 6, middle impeller; 7, rear return channel; 8, rear impeller; 9, volute chamber; 10, right sliding bearing; 11, right casing.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
In Fig. 1, left casing 1 is connected with right casing 11, volute chamber 9 is on right casing 11, front return channel 5 and rear return channel 7 are put into left casing 1, the right casing 11 that is connected, left sliding bearing 3, right sliding bearing 10 are placed into respectively in left casing 1 and right casing 11, and front impeller 4, middle impeller 6, rear impeller 8 are enclosed within on main shaft 2; The blade shape of front impeller 4, middle impeller 6, rear impeller 8 is not irregular curve form.
Working principle is that gas is entered by the intake grill on left casing 1, after front impeller 4 compressions, enter front return channel 5, during gas is imported, impeller 6 compresses for the second time, enter again rear return channel 7, after the blade of rear return channel 7 imports gas, impeller 8 compresses for the third time, discharges from exhaust outlet after being collected by the volute chamber 9 on right casing 11.
