Schematic diagram.
A kind of blast furnace cleaner intermediate bearing, blast furnace cleaner include the first conically shaped 1 setting up and down, intermediate bearing
3 and second conically shaped 5, intermediate bearing 3 include the first steel ring 9, the second steel ring 10 and third steel ring 11, the periphery of the first steel ring 9
Side wall is fixedly connected with rack gear 18, and the peace of the scraper 6 for installing cleaner is fixedly installed on the inner circumferential side wall of the first steel ring 9
Seat 7 is filled, the upper surface and lower end surface of the first steel ring 9 respectively offer an annular groove, and the second steel ring 10 and third steel ring 11 are distinguished
It is rotatably arranged in two annular grooves, the second steel ring 10 connects by the way that the tip of the first mounting flange 2 and the first conically shaped 1 is fixed
It connects, third steel ring 11 is fixedly connected by the second mounting flange 4 with the tip of the second conically shaped 5, the first mounting flange 2 and second
There are gaps between steel ring 10 and between the second mounting flange 4 and third steel ring 11.
One group of oil inlet passage 16, the inflow end of two groups of oil inlet passages 16 are respectively offered on second steel ring 10 and third steel ring 11
It is respectively facing the first mounting flange 2 and the second mounting flange 4, two groups of oil discharge passages 14 are offered on the first steel ring 9, in the first steel
The radially oil discharge passage 14 of circle 9 is located at the inside of oil inlet passage 16, two groups of oil discharge passages 14 in 9 rotation process of the first steel ring
End is flowed into correspondingly with two 16 alternate communications of oil inlet passage, and the outflow end of two groups of oil discharge passages 14 is respectively facing the first peace
Fill flange 2 and the second mounting flange 4.
Cleaner in the process of running, is rotated by driving motor band moving gear, and gear is engaged with gear ring drives the first steel
9 rotation of circle, the rotation of the first steel ring 9 drive mounting base 7 and scraper 6 to rotate, and carry out block clearing by scraper 6.Meanwhile it is logical to two groups of oil inlets
Lubricating oil is injected in road 16, lubricating oil is flowed into two groups of oil discharge passages 15 after flowing out from two groups of oil inlet passages 16, and is passed through
Two groups of oil discharge passages 15 are flowed between the first steel ring 9 and the first mounting flange 2 respectively and the first steel ring 9 and the second mounting flange
Between 4, the gap between the first steel ring 9 and the first mounting flange 2 and between the first steel ring 9 and the second mounting flange 4 is filled out
It is full, and to wash away to coal dust, coal dust can be prevented to enter, realization avoids coal dust from entering to cleaner internal flow
The purpose for causing intermediate bearing to damage in intermediate bearing.And entering the lubricating oil inside cleaner can be with one ignition of coal dust
It burns, will not pollute.
In order to reinforce sealing effect, between the first steel ring 9 and the first mounting flange 2 and the first steel ring 9 and second is installed
A felt seal ring 12 is each provided between flange 4, the outflow end of two groups of oil discharge passages 14 is respectively facing two felt seals
Circle 12.
Because lubricating oil is entering between the first steel ring 9 and the first mounting flange 2 and the first steel ring 9 and the second installation
After gap between flange 4, in addition to that can flow on the inside of cleaner, it is also possible to flow on the outside of to cleaner, flow outward
Lubricating oil can repeat to enter in intermediate bearing, lubricants capacity is excessive also to cause unfavorable shadow to the operation of intermediate bearing instead
It rings, so inward flange of the outflow end of oil discharge passage 14 close to felt seal ring 12, makes lubricating oil to flowing on the inside of cleaner
Resistance is less than to the resistance of flowing on the outside of cleaner enables lubricating oil to block clearing to play the role of guiding to lubricating oil
Flowing on the inside of machine.
