Abstract
The utility model discloses a multichannel rotary joint. The multichannel rotary joint comprises a flange, a porous shaft and a sleeve, wherein the flange is fixedly connected with the porous shaft, the porous shaft is arranged in the sleeve and is rotatably arranged in the sleeve, a plurality of feed holes are formed in the porous shaft, a filter element is arranged in each feed hole, flow holes which are matched with the feed holes are formed in the sleeve, and the feed holes are matched with and communicated with the flow holes to form feed channels. The multichannel rotary joint can prevent impurities in a liquid medium from blocking the feed channels when the liquid medium is delivered, and can really realize multichannel delivery.
Description
Technical field
The utility model relates to the fields such as metallurgical equipment, continuous caster turret and pneumatic steelmaking equipment; a kind of Multi-channel rotating joint particularly; be mainly used in supplying with various liquids and gases to working machine in the course of the work; under non-stop-machine state, give machine tool necessary all kinds of liquids and gases are provided.
Background technique
Metallurgy industry mostly is continuous productive process in each fields such as continuous casting, steel-making, and various liquid, gas must provide.Used swivel joint only can provide a kind of or two kinds of media at present, satisfy need of work and must use a plurality of swivel joints, and measure greatly the position that takes up room like this, installation and maintenance are very inconvenient, and the product structure of external import is also very unreasonable.Not yet find at present Multi-channel rotating joint of the present invention.
In order to solve the problems of the technologies described above, the patentee has proposed a kind of Multi-channel rotating joint on June 14th, 2004, its open day is on January 4th, 2006, comprise flange, porous shaft, overcoat, Sealing, bearing, end cap, have the different hole of the degree of depth corresponding one by one on the flange, flange is put together on by screw with porous shaft, has put bearing outward, porous shaft rotates arbitrarily in overcoat, between porous shaft and the overcoat seal arrangement is housed.But also there is following deficiency in actual applications in this patented technology: although can form multichannel in the porous shaft, less by the output channel behind the porous shaft, therefore, can not really form a plurality of passages in fact.Two, after long-time the use, when carrying liquid, the impurity in the liquid stops up transfer passage easily, causes swivel joint normally not use.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that existing Multi-channel rotating joint exists, a kind of novel multi-channel swivel joint is provided, impurity when the utility model can be avoided the conveying liquid body medium in the liquid medium stops up transfer passage, and can really realize channel transmission.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of Multi-channel rotating joint, comprise flange, porous shaft and overcoat, flange is fixedly connected with porous shaft, porous shaft is arranged in the overcoat, it is characterized in that: described porous shaft rotates and is arranged in the overcoat, is provided with a plurality of sprocket holes in the porous shaft, and is provided with filter member in the sprocket hole, put outward and be provided with the opening that cooperates with sprocket hole, sprocket hole cooperates with opening and is communicated with the formation transfer passage.
Be provided with Sealing between described porous shaft and the overcoat, and Sealing is between adjacent two openings.
Be provided with bearing in the described overcoat, porous shaft is rotationally connected by bearing and overcoat.
Sprocket hole in the described porous shaft is 3-15.
Described porous shaft is fixedly connected with by screw with flange.
Described outer putting is provided with end cover.
Employing the utility model has the advantage of:
One, in the utility model, described porous shaft rotates and is arranged in the overcoat, be provided with a plurality of sprocket holes in the porous shaft, and be provided with filter member in the sprocket hole, put outward and be provided with the opening that cooperates with sprocket hole, sprocket hole cooperates with opening and is communicated with the formation transfer passage, and the impurity in the time of can avoiding the conveying liquid body medium in the liquid medium stops up transfer passage, and has really realized the channel transmission medium.
Two, in the utility model, be provided with Sealing between described porous shaft and the overcoat, and Sealing can prevent the leakage between the liquid between adjacent two openings, also can prevent mixing between gas and the gas.
Three, in the utility model, be provided with bearing in the described overcoat, porous shaft is rotationally connected by bearing and overcoat, and this structure makes the reliability of rotation better, forms transfer passage thereby opening can be cooperated with sprocket hole exactly.
Four, in the utility model, the sprocket hole in the described porous shaft is 3-15, adopts this structure not only to realize channel transmission, also can avoid sprocket hole too much to affect porous shaft intensity.

Embodiment
A kind of novel multi-channel swivel joint, comprise flange 1, porous shaft 2 and overcoat 3, flange 1 is fixedly connected with porous shaft 2, porous shaft 2 is arranged in the overcoat 3, described porous shaft 2 rotates and is arranged in the overcoat 3, be provided with a plurality of sprocket holes 9 in the porous shaft 2, and be provided with filter member 10 in the sprocket hole 9, overanxious 10 mode has a lot, can select filter screen etc., and filter member can only be arranged in the liquid supplying port, but be not limited to filter screen, be provided with the opening that cooperates with sprocket hole 9 on the overcoat 3, sprocket hole 9 cooperates with opening and is communicated with the formation transfer passage, and the diameter of sprocket hole 9 is identical with the diameter of opening.
Preferred implementation of the present utility model is, is provided with Sealing 4 between described porous shaft 2 and the overcoat 3, and Sealing 4 is between adjacent two openings, and Sealing 4 can be selected difform Sealing.
Another preferred implementation of the present utility model is, is provided with bearing 5 in the described overcoat 3, and porous shaft 2 is rotationally connected by bearing 5 and overcoat 3, and the mode that is rotationally connected has a lot, is not limited to the mode of bearing.
