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 that the present invention adopts the half-closed water cooling plant of the distributor of unidirectional rotary mechanism;
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, the invention provides the half-closed water cooling plant of distributor adopting unidirectional rotary mechanism, this device is made up of distributor rotator 6, housing 7, water pump 11, gear 13, gear ring 14, cooling water channel and unidirectional rotary mechanism 12 etc.
The body of water pump 11 is connected on rotator 6.Gear ring 14 is annular internal tooth gear, is fixedly attached on housing 7, has tooth inside it outside it.The power input shaft of water pump 11 connects unidirectional rotary mechanism 12, and unidirectional rotary mechanism 12 connects gear 13, and gear 13 and gear ring 14 are gear internal messing relation.When distributor rotator 6 rotates relative to housing 7, the above-mentioned meshing relation of gear 13 reason and drive water pump shaft to turn round, water pump 11 is able to work.Due to the requirement of blast furnace work characteristics, rotator 6 must keep rotating, and therefore water pump 11 is able to non-stop run.When rotator 6 sense of rotation changes, unidirectional rotary mechanism 12 can ensure that water pump 11 turning direction is constant.
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 17 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 17, causes the gap between rotator 6 bottom and housing 7 to change, the namely back lash change of gear 13 and gear ring 14.
As shown in Figure 2, for solving this technical problem, the invention provides a kind of centering unit of rotator 6, this device is made up of support roller 16 and support roller circle 15 etc.
Support roller 16 is connected on rotator 6, and can turn round around himself axis.
Support roller circle 15 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 16 is arranged in the opposite of chute 17 center of gravity, and when rotator 6 and chute 17 common rotation, the external cylindrical surface of support roller 16 and the inner cylinder face of support roller circle 15 exist positive pressure, to resist the bias tendency that chute 17 brings.
The quantity of support roller 16 can have multiple, is preferably 2, is arranged in gear 13 both sides, to ensure back lash better.
The inner semi-enclosed cooling water channel of rotator 6 by rising pipe 1, inhalent siphon 2, enter tank 4, effluent trough 5, pump into water pipe 8, water pump outlet pipe 10, water pump 11 and cooling channel, bottom 9 form.
The top of rotator 6 inside is provided with into tank 4 and effluent trough 5, and bottom is provided with cooling channel, bottom 9.Enter tank 4 top and connect into water pipe 2, enter tank 4 bottom and connect the one end pumping into water pipe 8, the other end pumping into water pipe 8 connects water pump 11.Effluent trough 5 top connects rising pipe 1, one end of cooling channel, connection bottom, effluent trough 5 bottom 9, and the other end of cooling channel, bottom 9 connects one end of water pump outlet pipe 10, and the other end of water pump outlet pipe 10 connects water pump 11.The bottom of cooling channel, bottom 9 is semi-closed structure, and namely water coolant can only flow into from water pump outlet pipe 10, flows out to effluent trough 5.
The flow direction of water coolant is:
Distributor outside > inhalent siphon 2> enters tank 4> and pumps into cooling channel, water pipe 8> water pump 11> water pump outlet pipe 10> bottom 9> effluent trough 5> rising pipe 1.
For ensureing cooling performance, and preventing water coolant from spilling in blast furnace, entering in tank 4 and effluent trough 5 and being equipped with Level monitor.
The water level entering tank 4 need be kept above the water level of effluent trough 5, and when not turning round to make distributor, cooling-water flowing still can circulated at low velocity.
By said structure, the present invention can realize the normal work of water pump 11 in distributor, and the water coolant after water pump 11 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.
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.
