Description
Technical Field
The utility model relates to the field of blast furnace production, in particular to an improved clay gun machine rotary joint.
Background
The production of iron works in iron and steel enterprises is mainly blast furnace production, and the clay gun is a key device for blast furnace production. The mud gun belongs to the necessary stokehole equipment in the smelting industry, and has the function of quickly and accurately blocking a taphole after iron discharge so that a blast furnace can quickly enter the next cycle of operation.
Rotary joint for blast furnace ironmaking stokehold equipment clay gun, rotary joint's among the prior art sealing performance is good, connects the fastening, still it is abominable to have the operating mode condition, and the production rhythm is nervous, under the short condition of repair time, dismantles the difficulty, causes the overhaul of the equipments time delay, influences the production rhythm, can appear in the use because of the phenomenon that the rotatory overcoat that wearing and tearing caused and the body of switching-over were embraced, influences the result of use.
SUMMERY OF THE UTILITY MODEL
The utility model provides an improved clay gun rotary joint, which aims to solve the problem that the joint of the clay gun rotary joint in the prior art is difficult to disassemble in a short time.
The utility model adopts the specific scheme that: the improved mud gun rotating joint is characterized in that a hard pipe elbow is arranged at an oil way interface of the mud gun rotating joint and welded with a through joint, a first bearing is arranged between the top of a rotating outer sleeve of the mud gun rotating joint and a gland, and a second bearing is arranged between the rotating outer sleeve and a reversing body.
The second bearing is arranged between the lower shoulder of the reversing body and the bottom of the rotary outer sleeve
And a positioning sleeve is arranged outside the second bearing.
And a gasket is arranged between the gland and the rotary outer sleeve.
The first bearing is a deep groove ball bearing.
The second bearing is a thrust ball bearing.
Compared with the prior art, the utility model has the following beneficial effects:
1. according to the utility model, the hard pipe elbow is connected with the straight joint, the hard pipe elbow turns the oil pipe interface to be connected with the straight joint, the joint can be conveniently and rapidly disassembled to replace the oil pipe, the time for disassembling the flange is greatly saved, and the overhauling efficiency is greatly improved.
2. According to the utility model, the first bearing is arranged between the top of the rotating outer sleeve and the gland, so that the problem that the gap between the rotating outer sleeve and the gland is smaller and smaller in the use process is avoided, and the increase of the rotating friction force is reduced.
3. According to the utility model, the second bearing is arranged between the rotating outer sleeve and the reversing body, so that the problems of inflexible rotation and influence on the use effect caused by abrasion between the rotating outer sleeve and the reversing body are solved, the flexibility of the rotating outer sleeve is increased, and the service life is prolonged.

1. a bolt; 3. a gland; 4. a gasket; 5. sealing; 6. rotating the outer sleeve; 7. an oil line interface; 8. a commutator; 9. a first bearing; 10. a positioning sleeve; 11. a second bearing; 12. a hard pipe elbow; 13. a straight-through joint.
Detailed Description
The present invention will be described in further detail below with reference to the attached drawings, and it should be clearly understood herein that the described embodiments are not all embodiments, but are merely illustrative and not restrictive of the present invention.
The utility model provides an improved clay gun rotating joint, wherein a hard pipe elbow is arranged at an oil path interface of the clay gun rotating joint, the hard pipe elbow 12 is connected with a straight-through joint 13, a first bearing 9 is arranged between the top of a rotating outer sleeve 6 of the clay gun rotating joint and a gland 3, and a second bearing 11 is arranged between the rotating outer sleeve 6 and a reversing body 8. The second bearing 11 is arranged between the lower shoulder of the reversing body 8 and the bottom plane of the rotating outer sleeve 6, and a positioning sleeve 10 is arranged outside the second bearing 11; the first bearing 9 is a deep groove ball bearing; the second bearing 11 is a thrust ball bearing.
Original oil circuit piece (every department need be with 4M 12 hexagon socket head cap screws fastening), it is higher to the installation requirement, in case the installation is inaccurate will cause sealed skew, influence maintenance result to increase maintenance time, cause the secondary to leak after overhauing easily, cause equipment hidden danger or trouble. According to the utility model, the hard pipe elbow is arranged at the oil way interface and connected with the straight-through joint, the connection form of the 4 oil way blocks is directly changed into a loose joint connection form, the joint can be conveniently and quickly disassembled to replace an oil pipe, the time for disassembling a flange is greatly saved, and the overhauling efficiency is greatly improved.
The first bearing 9 is a deep groove ball bearing and plays a role in axially centering the rotating outer sleeve and the steering body, and the second bearing 11 is a thrust ball bearing and plays a role in bearing the downward gravity and the rotating friction force of the rotating outer sleeve and reducing the abrasion generated by friction.
The straight joint is an A-type straight joint.
The utility model adopts the hard pipe elbow to guide the pipe orifice of the oil pipe, and the space interval of the oil inlets is enlarged, thereby increasing the maintenance space, facilitating the concrete operation during maintenance, saving a large amount of maintenance time, and avoiding the faults of oil leakage and the like caused by the deviation of the oil way block from a plane.
The locating sleeve 10 is arranged outside the second bearing 11, the locating sleeve is used for isolating the bearing from an external dust area and bearing the abrasion of the gravity of the rotary outer sleeve to the shoulder of the steering body, the friction and the abrasion caused by the eccentricity are avoided, the rotation flexibility is ensured, the service cycle is prolonged, and the maintenance is avoided.
On the other hand, the second bearing is arranged between the rotating outer sleeve and the reversing body, so that the problems that the rotating outer sleeve and the reversing body are tightly matched to cause unsmooth rotation and influence the use performance of a rotating joint due to abrasion of a gasket caused by rotation between the rotating outer sleeve and the reversing body are solved. After the second bearing is additionally arranged, the rotating sleeve can freely rotate without adjusting the gap between the rotating sleeve and the reversing body, the problem of sinking locking is solved, the phenomenon of interference locking of two rotating surfaces is avoided, fault points are reduced, and faults are avoided.
The drawings and the explanation are only for one embodiment of the present invention, but the specific protection scope of the present invention is not limited to the above explanation, and any simple replacement or change within the technical idea of the present invention and the technical solution according to the present invention should be within the protection scope of the present invention.
