Description
Technical field
The utility model relates to a kind of sintering machine air intake devices, are used for sintering production technology field.
Background technique
Our factory 360m2Since operation, north and south 1# to 16# bellows and wind box branch pipe cause sintering machine by heavy corrosion
Bellows and branch pipe leak out seriously, influence normally to produce.To find out its cause, mainly existing sintering machine air intake device structure design is not
Rationally, FlexbleJoint is installed horizontal by 45 ° of angles, and corrosive liquids easily condenses in its inner wall, to substantially reduce
The service life of equipment；It is in high dummy status additionally, due to wind box branch pipe installation site, when replacing branch pipe, steel pipe need to be set up
Frame cuts off branch pipe by gas cutting, reuses crane lifting replacement, therefore the expense expenditure for replacing branch pipe is larger；And replace branch
Pipe belongs to high altitude operation, and there are biggish security risks, and lifting replacement process, time-consuming, difficulty is big.Due to large flue and branch pipe
Weld task difficulty is big, can not disposably be welded in place, and welding of doing over again need to be repeated several times, time-consuming and laborious.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sintering machine air intake device for the above-mentioned prior art,
Flanged joint, branch pipe are changed to by changing the shape and installation site of FlexbleJoint, and by branch pipe and large flue connection type
The resistance to material of internal spray anti-corrosion, greatly improves service life of equipment, when effectively reducing check man and maintenance cost.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of sintering machine air intake device, it includes big
Flue and bellows, the large flue are set to below 6 layers of platform of sintering machine, and the bellows are set to above 6 layers of platform of sintering machine,
The bellows bottom is provided with bellows valve, is provided with FlexbleJoint, the bellows valve and wave below the bellows valve
Connecting tube is provided between line compensator, the upper end of connecting tube is connected with bellows valve bottom by flange, the connection
It is connected at the top of pipe lower end and FlexbleJoint by flange, is provided with branch pipe below the FlexbleJoint, on the branch pipe
End is connected with FlexbleJoint bottom by flange, and the branch pipe lower end is connected with large flue by flange.
Preferably, the FlexbleJoint is arranged to circle.
Preferably, the FlexbleJoint is arranged in a vertical direction.
Preferably, the anti-corrosion layer of resistance to material is coated on the connecting tube and branch pipe wall.
Preferably, the branch pipe upper end is higher than 6 layers of 280~320mm of platform of sintering machine.
Compared with the prior art, the advantages of the utility model are:
1, the utility model is rectangular on the downside of bellows valve by bellows, FlexbleJoint and each component reasonable layout of branch pipe
FlexbleJoint is transformed into circle, and displacement is installed at 6 layers of platform of sintering machine and branch pipe flanged joint, can be conducive to disassembly in this way
Replacement reduces maintenance workload, reduces construction risk coefficient；
2, the utility model reduces maintenance by effectively improving service life of equipment in the resistance to material of branch pipe wall anticorrosion with painting
Working hour and maintenance cost；
3, branch pipe and large flue connection type are changed to flanged joint by the utility model, and flanged joint dismounting is more convenient,
Reduce maintenance duration, be not necessarily to site welding, thus avoid because welding quality it is unqualified caused by hidden trouble of equipment, for the efficient of sintering
High yield provides guarantee.
