Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of the half-closed reversible water cooling plant of distributor of the present invention;
Fig. 2 is the A-A sectional view in Fig. 1.
Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1, rotator 6, housing 7, water pump 13, gear 12 and gear ring 11 is comprised at the half-closed reversible water cooling plant of distributor of the present invention.
The body of water pump 13 is connected on rotator 6.Gear ring 12 is annular internal tooth gear, is fixedly attached on housing 7, has tooth inside it outside it.The power input shaft of water pump 13 connects gear 12, and gear 12 and gear ring 11 are gear internal messing relation.When rotator 6 rotates relative to housing 7, the above-mentioned meshing relation of gear 12 reason and drive water pump shaft to turn round, water pump 13 is able to work.Due to the requirement of blast furnace work characteristics, rotator 6 must keep rotating, and therefore water pump 13 is able to non-stop run.When rotator 6 sense of rotation changes, water pump 13 turning direction changes thereupon.
Rotator inside comprises semi-enclosed cooling water channel, drives the flow of cooling water in cold water water route when water pump rotates.This water route is made up of the first water pipe 1, second water pipe 2, first tank 4, second tank 5, pump first come in and go out water pipe 15, water pump 13 and cooling channel, bottom 9 of water pipe 14, pump second of coming in and going out of coming in and going out of coming in and going out of coming in and going out of coming in and going out.
The top of rotator 6 inside is provided with the first discrepancy tank 4 and the second discrepancy tank 5, and bottom is provided with cooling channel, bottom 9.First discrepancy tank 4 top connects the first discrepancy water pipe 1, first discrepancy cooling channel, connection bottom, tank 4 bottom 9.Second discrepancy tank 5 top connects the second discrepancy water pipe 2, second discrepancy cooling channel, connection bottom, tank 5 bottom 9.The side, bottom of cooling channel, bottom 9 connects pump first and to come in and go out water pipe 14, and opposite side connects pump second and to come in and go out water pipe 15.Pump first the come in and go out the other end of water pipe 15 of water pipe 14 and pump second of coming in and going out all is connected water pump 13.
When rotator 6 turns round with certain direction, the flow direction of water coolant is:
The outside > first of distributor water pipe 1> first cooling channel, tank 4> bottom 9> pump first water pipe 14> water pump 13> pump second water pipe 15> bottom cooling channel 9> second tank 5> second water pipe 2> distributor of coming in and going out of coming in and going out of coming in and going out of coming in and going out of coming in and going out of coming in and going out is outside.
When rotator 6 commutates revolution, the flow direction of water coolant is:
The outside > second of distributor water pipe 2> second cooling channel, tank 5> bottom 9> pump second water pipe 15> water pump 13> pump first water pipe 14> bottom cooling channel 9> first tank 4> first water pipe 1> distributor of coming in and going out of coming in and going out of coming in and going out of coming in and going out of coming in and going out of coming in and going out is outside.
By above structure, achieve the pressurization pump circulation of water coolant in rotator 6, and when rotator 6 sense of rotation changes, cooling water circulation direction is reversible.
For ensureing cooling performance, and preventing water coolant from spilling in blast furnace, in the first discrepancy tank 4 and the second discrepancy tank 5, being equipped with Level monitor.
Regardless of cooling water circulation direction, the water level entering tank need be kept above the water level of effluent trough, and when not turning round to make distributor, cooling-water flowing still can circulated at low velocity.
As shown in Figure 2, be connected by rotating bearing 3 between rotator 6 with housing 7.The effect of rotating bearing 3 can be regarded as large-sized thrust ball bearing.Because rotator 6 bottom hangs with the chute 16 of centre offset, therefore there is eccentric tendency during the two common rotation, and this bias tendency changes along with the pendulum angle of chute 16, causes the gap between rotator 6 bottom and housing 7 to change, the namely back lash change of gear 12 and gear ring 11.
For solving this technical problem, the invention provides a kind of centering unit of rotator 6, this device is made up of support roller 9 and support roller circle 10 etc.
Support roller 9 is connected on rotator 6, and can turn round around himself axis.
Support roller circle 10 is annular, and outside is fixedly attached on housing 7, and inner side is smooth, cylindrical peripheral surface.
Relative to the center of turning circle of rotator 6, support roller 9 is arranged in the opposite of chute 16 center of gravity, and when rotator 6 and chute 16 common rotation, the external cylindrical surface of support roller 9 and the inner cylinder face of support roller circle 10 exist positive pressure, to resist the bias tendency that chute 16 brings.
The quantity of support roller 9 can have multiple, is preferably 2, is arranged in gear 12 both sides, to ensure back lash better.
The present invention can realize the normal work of water pump 13 in distributor, and the water coolant after water pump 13 pressurizes quick and completely can be full of each position of cooling water channel, promotes cooling performance.Meanwhile, effective isolation of water coolant and the inner greasy dirt of distributor and dust can be realized, thus avoid the phenomenon such as fouling, blocking of cooling water channel.In addition, the pump circulation of water coolant bottom rotator internal cooling channel can play stirring water coolant, prevents the effect of greasy dirt and dust deposit.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
