Abstract
The utility model discloses a multi-channel rotating joint used for an iron notch of a blast furnace, and can convey various fluids in one rotating joint. The multi-channel rotating joint comprises two parts, that is an oil channel rotating joint and a water and air channel rotating joint. The utility model is characterized in that an outer flange is additionally arranged on an end cover of the oil channel rotating joint and fixedly by a bolt. The water and air channel rotating joint includes a mandrel fixed on the outer flange, a moving ring and a fixed ring around the mandrel, a positioning plate for positioning the moving ring and the fixed ring, and an ejector bush, and the whole water and air channel rotating joint is fixed on the outer flange. The multi-channel rotating joint can convey not only high-pressure oil but also high-pressure water and compressed air, and complicated water and air pipelines are not required to be added; the multi-channel rotating joint has a compact structure, the inside sealing performance is good, and no leakage appears; the number of channels can be adjusted at random according to field requirements, and fluids flowing in the channels can be changed; and the structure including the moving ring and the fixed ring is adopted, so that the fluids don't mix even in the case that a sealing ring is worn.
Description
Technical field
The utility model relates to that blast furnace taphole is opened, the pipe connection equipment of block apparatus, particularly a kind of blast furnace taphole hyperchannel swivel joint.
Background technology
In the blast furnace ironmaking production process, blast furnace taphole is opened, block apparatus is hydrostatic transmission, needs to transmit high-pressure oil, high pressure water, pressurized air.And the pipeline of these carrying high pressure Oil, Water, Gas needs constantly rotation, and this will have one can make the joint of pipeline rotation finish this work.The swivel joint of blast furnace taphole use at present can only be finished the transmission of high-pressure oil, and water, air-flow body will transmit by other plumbing installations.This just makes, and blast furnace taphole is opened, the connecting pipeline of block apparatus is intricate, wayward and management.The publication relevant with the application is " blast furnace chicksan ", open (bulletin) number: CN201058875.This swivel joint is made up of valve body, spool, rolling bearing, sealing-ring, has 4 with upper channel conveying high-pressure oil.The utility model is exactly to improve on the basis of this swivel joint, has increased water, gas passage, and perfect blast furnace taphole is with the function of swivel joint.
The utility model content
The utility model provides a kind of blast furnace taphole hyperchannel swivel joint, finishes the transmission of multiple fluid in a swivel joint.
The blast furnace taphole that the utility model provides is made up of oil circuit swivel joint and water, gas circuit swivel joint two portions with the hyperchannel swivel joint, the oil circuit swivel joint comprises the bolt and the pressing plate of oily passage, rolling bearing, fastening bearing, baffle plate, inside flange and fixed bolt, it is characterized in that on the end cap of oil circuit swivel joint, setting up an outward flange again, use bolting.Water, gas circuit swivel joint comprise that one is fixed on axle on the outward flange, is centered around rotating ring, stationary ring on the axle, the strongback of location rotating ring, stationary ring and top cover, whole water, gas circuit swivel joint are fixed on the outward flange by securing bolt and packing ring by axle, rotating ring and stationary ring inside are provided with cavity, be interconnected between the cavity, two sealing-rings respectively are housed in rotating ring cavity and stationary ring cavity, and rotating ring and stationary ring rotate arbitrarily around axle, in the rotary course rotating ring cavity with decide the annular space chamber and communicate.In the rotating ring cavity, draw the high pressure water passage, in the stationary ring cavity, draw compressed air channel.
The blast furnace taphole that the utility model provides is compared with existing swivel joint with the hyperchannel swivel joint, and its significant beneficial effect is embodied in:
From single transmission high-pressure oil to transmitting high pressure water and pressurized air, avoided that blast furnace taphole is opened, increased complicated water, air pipe in the block apparatus.
2. blast furnace taphole is with hyperchannel rotary joint structure compactness, and seal inside is good, does not reveal.
3. blast furnace taphole can arbitrarily be adjusted number of channels according to on-the-spot needs with the hyperchannel swivel joint, and can change the fluid that is led in the passage.
4. adopt rotating ring, stationary ring structure, under the ring wear situation, various fluids are not gone here and there mutually.
Description of drawings
Fig. 1 is a blast furnace taphole hyperchannel swivel joint front view synoptic diagram; Fig. 2 is a blast furnace taphole hyperchannel swivel joint left view synoptic diagram.
Embodiment
As shown in Figure 1 and Figure 2, blast furnace taphole is made up of oil circuit swivel joint 1 and water, gas circuit swivel joint two portions with the hyperchannel swivel joint, oil circuit swivel joint 1 comprises the bolt 4 and the pressing plate 5 of oily passage 2, rolling bearing 3, fastening bearing, baffle plate 6, inside flange 7 and standing bolt 8,9.On the end cap of oil circuit swivel joint 1, set up an outward flange 12 again, fixing with bolt 10,11.Water, gas circuit swivel joint comprise that one is fixed on axle 13 on the outward flange 12, is centered around rotating ring 14, stationary ring 15 on the axle, the strongback 16 of location rotating ring, stationary ring and top cover 19, whole water, gas circuit swivel joint are fixed on the outward flange 12 by securing bolt 17 and packing ring 18 by axle 13, rotating ring 14 and stationary ring 15 inside are provided with cavity, be interconnected between the cavity, in rotating ring 14 cavitys He in stationary ring 15 cavitys, two sealing-rings 21 are housed respectively, rotating ring and stationary ring rotate arbitrarily around axle, in the rotary course rotating ring cavity with decide the annular space chamber and communicate.In rotating ring 14 cavitys, draw high pressure water passage 20, in stationary ring 15 cavitys, draw compressed air channel 22.The sealing-ring that is equipped with in rotating ring and stationary ring cavity guarantees cavity leak fluid not under rotation and stationary state.
