Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation that this utility model adopts the half-closed water cooling plant of distributing device of two way water pump；
Fig. 2 is the A-A sectional view in Fig. 1.
Detailed description of the invention
In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, now comparison accompanying drawing describes detailed description of the invention of the present utility model in detail.
As it is shown in figure 1, the half-closed water cooling plant of distributing device of employing two way water pump of the present utility model includes distributing device rotary body 6, housing 7, two way water pump 11, gear 12 and gear ring 13.
The body of two way water pump 11 is connected on rotary body 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 two way water pump 11 connects gear 12, and gear 12 and gear ring 13 are gear internal messing relation.When distributing device rotary body 6 rotates relative to housing 7, the above-mentioned meshing relation of gear 12 reason and drive the power input shaft of two way water pump to turn round, two way water pump 11 is able to work.Rotary body 6 is internal includes semi-enclosed cooling water channel, drives the flow of cooling water in cooling water channel when two way water pump 11 rotates.
Due to blast furnace work characteristics requirement, rotary body 6 must keep rotating, and therefore two way water pump 11 is able to continuous operation.When rotary body 6 direction of rotation changes, two way water pump 11 can ensure that water inlet and outlet are constant.
As in figure 2 it is shown, be connected by pivoting support 3 between rotary body 6 with housing 7.The effect of pivoting support 3 can be regarded as large-sized thrust ball bearing.Owing to rotary body 6 bottom hangs with the chute 16 of centre offset, therefore there is bias tendency during the two common rotation, and this bias tendency changes along with the pendulum angle of chute 16, the gap between rotary body 6 bottom and housing 7 is caused to change, namely the back lash change of gear 12 and gear ring 13.
For solving this technical problem, this utility model provides the centring means of a kind of rotary body 6, and this device is made up of support roller 15 and support roller circle 14 etc..Support roller 15 is connected on rotary body 6, and can turn round around himself axis.Support roller circle 14 is annular, and outside is fixedly attached on housing 7, and inner side is smooth, cylindrical peripheral surface.
Relative to the centre of gyration of rotary body 6, support roller 15 is arranged in the opposite of chute 16 center of gravity, and when rotary body 6 and chute 16 common rotation, the inner cylinder face of the external cylindrical surface of support roller 15 and support roller circle 14 exists normal pressure, to resist the eccentric tendency that chute 16 brings.
The quantity of support roller 15 can have multiple, it is preferred to 2, is arranged in gear 12 both sides, to better ensure that back lash.
The internal cooling water channel closed of rotary body 6 by outlet pipe 1, oral siphon 2, enter tank 4, effluent trough 5, pump into water pipe 8, water pump outlet pipe 10, two way water pump 11 and cooling duct, bottom 9 form.
Top within rotary body 6 is provided with into tank 4 and effluent trough 5, and bottom is provided with cooling duct, bottom 9.
Entering 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 two way water pump 11.
Effluent trough 5 top connects outlet pipe 1, one end of cooling duct, connection bottom, effluent trough 5 bottom 9, and the other end of cooling duct, bottom 9 connects one end of water pump outlet pipe 10, and the other end of water pump outlet pipe 10 connects two way water pump 11.
The bottom of cooling duct, bottom 9 is semi-closed structure, and namely cooling water can only flow into from water pump outlet pipe 10, flows out to effluent trough 5.
The flow direction of cooling water is:
Outside distributing device > oral siphon 2 > enter tank 4 > pump into water pipe 8 > two way water pump 11 > water pump outlet pipe 10 > cooling duct, bottom 9 > effluent trough 5 > outlet pipe 1.
For ensureing cooling effect, and prevent cooling water from spilling in blast furnace, enter in tank 4 and effluent trough 5 and be equipped with Level monitor.
The water level entering tank 4 need to be kept above the water level of effluent trough 5, still can circulated at low velocity so that cooling down current when distributing device does not turn round.
By said structure, this utility model is capable of two way water pump normal operation in distributing device, the cooling water after two way water pump pressurizes can each position of quick and complete full cooling water channel, promote cooling effect.Simultaneously, it may be achieved being effectively isolated of the internal greasy dirt of cooling water and distributing device and dust, thus avoiding the phenomenons such as the fouling of cooling water channel, blocking.
Above in conjunction with accompanying drawing, embodiment of the present utility model is described; but this utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is merely schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; without departing under this utility model objective and scope of the claimed protection situation, it may also be made that a lot of form, these belong within protection of the present utility model.
