Abstract

The utility model relates to the centrifugal blower field is a mass -flow oxygen production three -dimensional flow centrifugal blower. Comprise left casing, main shaft, left slide bearing, right slide bearing, right casing, characterized by left side casing fuses with right casing, and the volute chamber is on right casing, and preceding backward flow ware flows back the ware after with and puts into the left casing that fuses, right casing, during left slide bearing, right slide bearing lay left casing and right casing respectively, preceding impeller, well impeller after, the impeller overlap on the main shaft. Since adopted this technical scheme, compact structure, and efficient, power consumptive province has practiced thrift the energy, the cost is reduced.

Description

A kind of Mass-flow oxygen production three-dimensional flow centrifugal blower

Technical field

This utility model relates to centrifugal blower field, is a kind of Mass-flow oxygen production three-dimensional flow centrifugal blower.

Background technology

In large-scale oxygenation project, owing to oxygen making amount is big, therefore it is required that the air capacity that centrifugal blower provides is big, simultaneously because the needs of oxygen technological process processed, require that height is wanted in the air boosting that aerator provides, reach 200kPa, big-flow high-pressure centrifugal blower, the merit consumed is very big, current big flow oxygen centrifugal blower, and its efficiency is between 82-83%, one big flow boosting is the oxygen centrifugal blower processed of 200kPa, wasted work, at more than 6640kW, is run 24 hours every days continuously, and the electric energy consumed every year is very large.

Summary of the invention

The purpose of this utility model is to provide for a kind of efficiency height, the big-flow high-pressure power oxygen centrifugal blower of power consumptive province.

The technical solution of the utility model is: be made up 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 in right casing, front return channel and rear return channel are put in the left casing being connected, right casing, left sliding bearing, right sliding bearing are placed in left casing and right casing respectively, and front impeller, middle impeller, rear impeller set are on main shaft.

Owing to have employed technique scheme, compact conformation, efficiency is high, power consumptive province, has saved the energy, has reduced cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

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.

Detailed description of the invention

With embodiment, this utility model is further described below in conjunction with the accompanying drawings.

In FIG, left casing 1 is connected with right casing 11, volute chamber 9 is in right casing 11, front return channel 5 and rear return channel 7 put into be connected left casing 1, in right casing 11, left sliding bearing 3, right sliding bearing 10 are placed in left casing 1 and right casing 11 respectively, and front impeller 4, middle impeller 6, rear impeller 8 are enclosed within main shaft 2.

Operation principle is that gas is entered by the air inlet in left casing 1, after front impeller 4 compresses, return channel 5 before entering, introduce gas into the second time compression of middle impeller 6, enter back into rear return channel 7, the blade of rear return channel 7 introduces gas into the third time compression of rear impeller 8, the volute chamber 9 in right casing 11 discharge from air outlet after collecting.
