Description
Technical field
The invention belongs to Power Machinery Engineering professional domains, are related to a kind of double drive type coaxial electrospinnings.
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, the basic structure of conventional energy recovery turbine coaxial electrospinning (BPRT unit) are as follows: motor and energy regenerating
Turbine is separately mounted to the both ends of blast furnace blower along axial direction.Wherein, it needs to be arranged between motor and blast furnace blower (compressor)
The revolving speed of motor is increased to revolving speed identical with compressor by one speeder (gear-box).Due in motor and compressor chamber
Provided with speeder, increase the complexity of shafting and the failure rate of equipment operation, at the same also increase unit investment and
Operation expense.In addition, speeder is during transmitting torque, there are certain energy losses.
In addition, in practice it has been found that (blast furnace rouses when energy recovery turbine breaks down or needs regular maintenance
Blower should not be shut down at this time), since the gap of speed change clutch itself or greasy filth accumulation will appear the servo-actuated of energy recovery turbine
Problem, to cannot achieve normal maintenance；At the same time, it is servo-actuated the loss that can also bring the energy.
Summary of the invention
The purpose of the utility model is to provide it is a kind of more efficiently, failure rate is lower, the overall compact coaxial machine of structure
Group.
In order to achieve the goal above, the utility model proposes following solution:
The direct-connected double drive type coaxial electrospinnings of the high speed, including high-speed motor, compressor, clutch and energy recovery turbine；Its
In, high-speed motor and energy recovery turbine are separately mounted to the both ends of compressor, the revolving speed of high-speed motor and the revolving speed of compressor
Quite, range of speeds 3000r/min~8000r/min；High-speed motor is directly connected to by shaft coupling and compressor, energy regenerating
Turbine is connect by clutch with compressor.
Further, the clutch is timing clutch or speed change clutch.
Further, the energy recovery turbine is Blast Furnace Gas Turbine machine or steam turbine expanding machine.
Further, it is provided with brake apparatus on the clutch.The preferred dish-style brake apparatus of brake apparatus or pressure lever type system
Dynamic device.
Further, described brake apparatus itself is mounted on the shaft coupling between energy recovery turbine and speed change clutch
On device shield.
The utility model has the following beneficial effects:
1, it eliminates electricity and drags speeder in compressor set, directly connect with compressor by high-speed motor, improve electricity
The transfer efficiency and unit reliability of operation of energy, meanwhile, reduce equipment investment and operation cost.
2, based on " servo-actuated " problem found in applicant's practice, by speed change clutch or in coal-gas turbine
Individual brake apparatus is set on the shaft coupling between speed change clutch, is needing to overhaul Blast Furnace Gas Turbine machine
When, shaft coupling or axis are directly acted on by brake apparatus, can quickly, it is easy, reliably shut down, be detached from the pass with air blower
Connection；Meanwhile also accordingly avoiding the loss of the energy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment one.
Fig. 2 is the structural schematic diagram of embodiment two.
Fig. 3 is the scheme of installation of pressure lever type brake apparatus.
Specific embodiment
Embodiment one
As shown in Figure 1, the direct-connected double drive type coaxial electrospinnings of the high speed include the high-speed motor set gradually along axial direction, compression
Machine, timing clutch and energy recovery turbine；High-speed motor and energy recovery turbine are matched with compressor rotary speed, i.e. motor, energy
It is identical as compressor rotary speed to measure recovery gas turbine revolving speed, reaches high-speed motor and compressor is directly connected to by shaft coupling, without matching
It sets speed change gear and carries out transformation of speed, high-revolving energy recovery turbine is connect by timing clutch with compressor, without
Speed change gear is set.
Embodiment two
As shown in Fig. 2, the direct-connected double drive type coaxial electrospinnings of the high speed include the high-speed motor set gradually along axial direction, compression
Machine, speed change clutch and energy recovery turbine；High-speed motor is matched with compressor rotary speed, is reached high-speed motor and is passed through with compressor
Shaft coupling is directly connected to, and carries out transformation of speed without configuring speed change gear；Energy recovery turbine revolving speed is different from compressor rotary speed,
It is connect again with compressor after need to carrying out speed change by the speed change clutch with speed changing function.
On shaft coupling on the clutch or between coal-gas turbine and clutch, settable brake apparatus.Such as Fig. 3
It is shown, it specifically can be pressure lever type brake apparatus, be mainly made of components such as brake block 1, compression bars 2, pressure lever type brake apparatus sheet
Body is fixedly installed on the shield 3 of shaft coupling.It is direct by brake apparatus when needing to overhaul Blast Furnace Gas Turbine machine
Act on shaft coupling or axis 4, can quickly, it is easy, reliably shut down, be detached from and to be associated with air blower；Meanwhile it also mutually should be avoided
The loss of the energy.
