Description

Rotating device and rotary kiln

Technical Field

The application relates to the technical field of metallurgical equipment, in particular to a rotating device and a rotary kiln.

Background

In the prior rigid pipeline for conveying high-pressure fluid, a rigid rotary joint is generally used for connecting two parts which rotate relatively, so that the two ends can still convey the medium in the pipeline when the two ends keep moving relatively. Specifically, the rigid rotary joint is connected at two ends by a hollow shaft sleeve structure, one end is a hollow shell which is connected with the rotary component and can rotate, and the other end is a static hollow shell which is connected with a relatively static rigid pipeline. In order not to let the high pressure medium leak from the rotational position, the part is provided with a seal to ensure tightness and prevent leakage.

The burner pipe of the conventional rotary kiln is equipped with a rigid rotary joint, as shown in fig. 1, a burner device 2' and a rigid rotary joint 1' are fixed on a rotary kiln 3', one end of the rigid rotary joint 1' is connected with the burner device through a metal hose, and the other end of the rigid rotary joint 1' is connected with a fixed pipe 5' through a metal hose 4 '. As shown in fig. 2, fig. 2 is a schematic view of the rotary kiln 3 'in fig. 1 after rotating a certain angle, it can be seen that the burner device 2' and the rigid rotary joint 1 'rotate by the same angle along with the rotary kiln 3' while maintaining the relative positions, and the metal hose 4 'is elongated due to the change of the position of the rigid rotary joint 1', but the rotation characteristic of the rigid rotary joint 1 'ensures that the metal hose 4' is not damaged due to torsion. It is also ensured that the normal use of the burner device 2 'is not affected when the rotary kiln 3' is rotating.

However, since the rigid rotary joint is more expensive than the conventional pipeline, and the rigid rotary joint needs to be installed on the furnace wall, the ambient working temperature is high during normal production, which easily affects the service life of the sealing material of the rigid rotary joint, and causes the risk of gas leakage inside the pipeline. In view of this, the present application provides a rotating device to satisfy the stability of the product while saving the cost.

Detailed Description

The present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 3 and 4 in combination, the present application provides a rotary device 1 and a rotary kiln. Wherein the rotating device 1 is used for conveying fluid, and the rotating device 1 can be applied to a rotary kiln and rotates along with a furnace body 2 of the rotary kiln.

Referring to fig. 5 to 9, in the embodiment of the present application, the rotating device 1 includes a positioning joint 11 and a rotating assembly 12. Wherein, one of the rotating component 12 and the positioning joint 11 has a rotating shaft, the other has a rotating hole 121, the rotating shaft is rotatably matched with the rotating hole 121, and the rotating component 12 is further provided with a connecting channel (not labeled).

Specifically, the rotating assembly 12 may be provided with a rotating hole 121, and the positioning joint 11 may be provided with a rotating shaft; or, the rotating assembly 12 is provided with a rotating shaft, and the positioning joint 11 is provided with a rotating hole 121. In one embodiment, the positioning joint 11 forms a rotation shaft, and the rotation component 12 defines a rotation hole 121.

Referring to fig. 3 and 4 again, taking the application of the rotary device 1 to a rotary kiln as an example, a burner 21 is disposed on the furnace body 2 of the kiln, one end of the connecting channel is connected to the burner 21 through a first metal hose 22, and the other end of the connecting channel is connected to an external fixed pipeline through a second metal hose 23. The positioning joint 11 is fixed with the furnace body 2, so that the positioning joint 11 does not rotate relative to the furnace body 2. The rotating assembly 12 is rotatably connected with the positioning joint 11, the rotation axis between the rotating assembly 12 and the positioning joint 11 is generally along the horizontal direction, and due to the action of the self gravity of the rotating assembly 12, no matter which position the rotary kiln rotates to, the rotating assembly 12 always keeps the original state, namely, the connecting channel is supposed to be in the vertical state, after the kiln rotates, the upper position and the lower position of the rotating assembly are not changed, and the connecting channel still keeps the vertical state, so that the phenomenon that the second metal hose 23 connected with the rotating assembly is twisted and damaged is avoided.

As shown in fig. 3 and 4, fig. 4 is a state diagram of the kiln in fig. 3 after rotation, and it is obvious from the figure that, in the process that the whole rotating device 1 rotates by the same angle along with the furnace body 2, the rotating assembly 12 also rotates under the action of self gravity by taking the positioning joint 11 as a center, so that the horizontal state is always maintained.

In one embodiment, the positioning joint 11 is welded to the furnace body 2. Of course, in other embodiments, the positioning joint 11 may be fixed to the furnace body 2 by screws.

Referring to fig. 5-7 in combination, the rotating component 12 has first and second surfaces facing away from each other and distributed along the axis of rotation between the rotating component 12 and the locating joint 11. Wherein, one end of the positioning joint 11 is provided with an external thread, the rotating device 1 further comprises a locking nut 13 matched with the external thread, and the locking nut 13 can be abutted against the first surface; and/or, the other end of the positioning joint 11 is provided with a limiting projection 111, and the limiting projection 111 can be abutted with the second surface.

Or, a plurality of limiting protrusions 111 are arranged on the side surface of the positioning joint 11, and the limiting protrusions 111 are arranged at intervals along the circumferential direction of the positioning joint 11. Or, a limit protrusion 111 is arranged on the side surface of the positioning joint 11, and the limit protrusion 111 is block-shaped. In this embodiment, the limiting protrusion 111 is formed by integrally processing the positioning joint 11. In other embodiments, the limiting protrusion 111 and the positioning joint 11 may be two separate structures.

In this embodiment, after the positioning joint 11 passes through the rotation hole 121 (as shown in fig. 8), the lock nut 13 is engaged with the external thread on the positioning joint 11, at this time, the lock nut 13 can limit the positioning joint 11 to move backward to be separated from the rotation hole 121 by abutting against the first surface, and the limit protrusion 111 can limit the positioning joint 11 to move forward to be separated from the rotation hole 121 by abutting against the second surface. In this embodiment, one end of the positioning joint 11 having the limiting protrusion 111 is fixed to the furnace body 2. Here, the side where the limiting protrusion 111 is located is the rear, and the side where the external thread is located is the front.
