Description
Technical field
The utility model belongs to Power Machinery Engineering professional domain, in particular to a kind of double drive blast furnace air unit.
Background technique
Blast furnace blower is the important component of blast fumance, and function is that air pressurized is sent into blast furnace, provides height
The wind pressure and oxygen that furnace ironmaking needs.Blast furnace blower is the big energy consumption equipment in system for blast furnace ironmaking, accounts for ironmaking total energy consumption
10% or so.
Currently, universal scheme is: motor and Blast Furnace Gas Turbine machine are separately mounted to blast furnace blower along axial direction
Both ends, motor are connect by gear-box with blast furnace blower, and Blast Furnace Gas Turbine machine passes through speed change clutch and blast furnace air
Machine connection.
In practice, it has been found that (the blast furnace blower when Blast Furnace Gas Turbine machine breaks down or needs regular maintenance
Should not shut down at this time), since the gap of speed change clutch itself or greasy filth accumulation will appear the servo-actuated problem of coal-gas turbine, from
And it cannot achieve normal maintenance；At the same time, it is servo-actuated the loss that can also bring the energy.
Utility model content
In order to ensure to the normal service work of Blast Furnace Gas Turbine machine, while the operation of blast furnace blower is not influenced, this
Utility model provides a kind of double drive blast furnace air unit of braking device.
The solution of the utility model is as follows:
The double drive blast furnace air unit of the braking device, including the motor, gear-box, height set gradually along axial direction
Stove air blast and coal-gas turbine, wherein coal-gas turbine is connect by shaft coupling and speed change clutch with blast furnace blower, electricity
Motivation is connect by gear-box with blast furnace blower；Main improvement is: on the speed change clutch or in Gas Turbine
It is provided with brake apparatus on shaft coupling between machine and speed change clutch, it is straight to speed change clutch or shaft coupling for respective needle
It practices midwifery raw braking action.
Further, the brake apparatus can be dish-style brake apparatus, be fixedly connected with the cabinet of speed change clutch；System
Dynamic device acts on the slow-speed shaft free end of speed change clutch.Alternatively, the brake apparatus is also possible to pressure lever type brake apparatus,
It is fixedly connected with the shield of shaft coupling；Brake apparatus acts on the shaft coupling between coal-gas turbine and speed change clutch.
Further, the blast furnace blower is axial flow compressor or centrifugal compressor.
Further, the coal-gas turbine is axial-flow type coal-gas turbine.
Further, the speed change clutch is the combined speed change clutch that gearbox and clutch are constituted.
The utility model has the following beneficial effects:
Based on " servo-actuated " problem for finding in applicant's practice, by speed change clutch or in coal-gas turbine and
Individual brake apparatus is set on the shaft coupling between speed change clutch, when needing to overhaul Blast Furnace Gas Turbine machine,
Directly act on shaft coupling or axis by brake apparatus, can quickly, it is easy, reliably shut down, be detached from and to be associated with air blower；
Meanwhile also accordingly avoiding the loss of the energy.

End, coal-gas turbine are connect by speed change clutch with main blast furnace blower, and motor passes through gear-box and main blast furnace blower
Connection.By increasing brake apparatus in double drive blast furnace air unit, specifically may be provided on speed change clutch or in coal
In first shaft coupling between gas turbine and speed change clutch.
Brake apparatus can be dish-style brake apparatus, mainly be made of disk, brake block and its ancillary equipment, such as Fig. 4 institute
Show.Dish-style brake apparatus may be disposed at the point of A shown in Fig. 1-Fig. 3 or B point any position.As shown in figure 5, best position is
B point (slow-speed shaft free end) in Fig. 2, dish-style brake apparatus itself is fixedly installed on the cabinet of speed change clutch.
Brake apparatus is also possible to pressure lever type brake apparatus, is mainly made of components such as brake block, compression bars, as shown in Figure 6.
Pressure lever type brake apparatus may be disposed at the point of A shown in Fig. 1-Fig. 3, B point or C point any position, embodiment shown in Fig. 6 and show
Best position is C point, and pressure lever type brake apparatus itself is fixedly installed on the shield of shaft coupling.
In the same system, dish-style brake apparatus and pressure lever type brake apparatus can be used respectively in position at two.
When needing to overhaul Blast Furnace Gas Turbine machine, shaft coupling or axis, energy are directly acted on by brake apparatus
Enough quickly, it simplicity, reliably shuts down, disengaging is associated with air blower；Meanwhile also accordingly avoiding the loss of the energy.
