Description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing：
Fig. 1 is structural representation of the present invention using the half-closed water cooling plant of distributing device of two way water pump；
Fig. 2 is the A-A sectional views in Fig. 1.
Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now compare accompanying drawing and describe in detail
The specific embodiment of the present invention.
As shown in figure 1, the half-closed water cooling plant of distributing device of the employing two way water pump of the present invention includes distributing device rotary body
6th, 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, and its outside is fixedly attached to
On housing 7, its inner side is with teeth.The power input shaft connection gear 12 of two way water pump 11, gear 12 is to nibble in gear with gear ring 13
Conjunction relation.When distributing device rotary body 6 rotates relative to housing 7, the above-mentioned meshing relation of the reason of gear 12 and drive two way water pump
Power input shaft revolution, two way water pump 11 is able to work.The inside of rotary body 6 includes semi-enclosed cooling water channel, two way water pump
11 drive the flow of cooling water in cooling water channel when rotating.
Because blast furnace work characteristics is required, rotary body 6 must keep rotation, therefore two way water pump 11 continuously to be worked.
When the direction of rotation of rotary body 6 changes, two way water pump 11 can ensure that water inlet and outlet are constant.
As shown in Fig. 2 being connected by pivoting support 3 between rotary body 6 and housing 7.The effect of pivoting support 3 can be regarded as greatly
The thrust ball bearing of size.Because the bottom of rotary body 6 hangs with the chute 16 of centre offset, therefore exist during the two common rotation inclined
The heart is inclined to, and the bias tendency changes with the pendulum angle of chute 16, between causing between the bottom of rotary body 6 and housing 7
Gap changes, that is, the back lash change of gear 12 and gear ring 13.
To solve the technical problem, the present invention provides a kind of centring means of rotary body 6, and the device is by support roller 15 and support roller
Enclose 14 grades composition.Support roller 15 is connected on rotary body 6, and can be around its own axis revolution.Support roller circle 14 is annular, and outside is solid
Surely it is connected on housing 7, 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 the center of gravity of chute 16, when rotary body 6 and chute
During 16 common rotation, there is normal pressure in the external cylindrical surface of support roller 15, brought with resisting chute 16 with the inner cylinder face of support roller circle 14
Eccentric tendency.
The quantity of support roller 15 can have multiple, preferably 2, be arranged in the both sides of gear 12, to better ensure that between engagement
Gap.
The cooling water channel of the inside of rotary body 6 closing 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 bottom cooling duct 9 constitute.
Top inside rotary body 6 is provided with into tank 4 and effluent trough 5, and bottom is provided with bottom cooling duct 9.
Enter the top of tank 4 connection oral siphon 2, enter one end that the connection of the bottom of tank 4 pumps into water pipe 8, pump into the another of water pipe 8
End connection two way water pump 11.
The top of effluent trough 5 connects outlet pipe 1, and the bottom of effluent trough 5 connects one end of bottom cooling duct 9, and bottom cooling is logical
The other end in road 9 connects one end of water pump outlet pipe 10, the other end connection two way water pump 11 of water pump outlet pipe 10.
The bottom of bottom cooling duct 9 can only flow into for semi-closed structure, i.e. cooling water from water pump outlet pipe 10, flow out to out
Tank 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>Bottom cooling is logical
Road 9>Effluent trough 5>Outlet pipe 1.
To ensure cooling effect, and prevent cooling water from spilling in blast furnace, enter in tank 4 and effluent trough 5 and be equipped with water
Position monitoring device.
Entering the water level of tank 4 need to be kept above the water level of effluent trough 5, so that cool down current when distributing device is not turned round still can be low
Speed circulation.
By said structure, the present invention can realize normal work of the two way water pump in distributing device, and Jing two way water pumps add
Cooling water after pressure can quick and complete each position full of cooling water channel, lifted cooling effect.Meanwhile, it is capable of achieving cooling water
It is effectively isolated with distributing device inside greasy dirt and dust, so as to avoid the phenomenon such as fouling, blocking of cooling water channel.
Embodiments of the invention are described above in conjunction with accompanying drawing, but be the invention is not limited in above-mentioned concrete
Embodiment, above-mentioned specific embodiment is only schematic, rather than restricted, one of ordinary skill in the art
Under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, can also make a lot
Form, these are belonged within the protection of the present invention.
