Description

Technical Field

[0001] The utility model relates to the technical field of chemical drying equipment, in particular to a locking device for a rotary kiln roller ring. Background Art

[0002] Chemical production often requires the use of rotary kilns in many processes. The primary function of a rotary kiln is to exchange heat between materials and hot air within the furnace. The stable operation of the equipment directly impacts product performance. The furnace body and rollers of a rotary kiln are typically secured with a 3° sloped bar iron that is inserted and clamped, reinforced by high-temperature welding. This method can cause welds to fall off during high-temperature heating and prolonged operation, leading to the loss of the iron iron. This can cause the rollers and furnace body to misalign and operate concentrically, significantly reducing the service life of the rotary kiln. Summary of the Invention

[0003] The technical problem to be solved by the utility model is that the strip-shaped oblique iron between the rolling ring and the rotary kiln furnace body is easy to fall off during long-term operation, resulting in the rolling ring and the furnace body being misaligned and unable to operate concentrically.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a locking device for the rotary kiln roller ring, including a limiting flange ring, a sleeve ring and a connecting ring coaxially sleeved on the roller ring body, the connecting ring is fixedly welded to the roller ring body, the limiting flange ring is fixed on the end wall of the connecting ring, the two end walls of the sleeve ring both abut against the limiting flange ring, and the limiting flange ring is connected to the end wall of the sleeve ring through a force transmission pin.

[0005] Preferably, a reinforcing rib plate with a triangular structure is connected between the outer side surface of the connecting ring and the end wall of the limiting flange ring, and the reinforcing rib plates are distributed at equal angles on the connecting ring.

[0006] Preferably, a connecting hole for installing the force transmission pin is opened on the end wall of the collar, the connecting hole and the force transmission pin are clearance-matched, and the end wall of the force transmission pin is welded to the limiting flange ring.

[0007] Preferably, the force transmission pins are distributed at equal angles around the axis of the rolling ring body.

[0008] Preferably, a mounting groove is provided on the connecting ring, a force transmission block is provided in the mounting groove, the force transmission block is fixedly connected to the outer wall of the rolling ring body, and a connecting groove for inserting the end of the force transmission block is provided on the end wall of the ring.

[0009] Preferably, the cross-section of the force transmission block is T-shaped, the connecting groove is a T-shaped groove, and the outer side wall of the force transmission block fits with the inner side wall of the connecting groove.

[0010] Preferably, an oblique rib is provided on one end of the force transmission block away from the collar, and the oblique rib is connected to the outer side wall of the rolling ring body.

[0011] The utility model provides a locking device for a rolling ring of a rotary kiln, which clamps the sleeve ring by two limiting flange rings and fixes the limiting flange ring by a connecting ring, thereby preventing the rolling ring from axial movement; the strength of the limiting flange ring is improved by a reinforcing rib plate; a force transmission block is installed on the rolling ring body, and the force transmission block is adapted to a connecting groove of the sleeve ring end wall, so that the sleeve ring is locked between the two limiting flange rings, ensuring that the rolling ring will not shift or deviate during high-temperature heating and rotation, thereby extending the service life of the equipment and solving the problem of oblique iron falling off caused by falling off of welding parts during high-temperature heating and long-term operation of the furnace body; at the same time, it also effectively solves the problem that the rolling ring and the furnace body are misaligned and cannot run concentrically, thereby greatly extending the service life of the rotary kiln and improving production efficiency.

[0017] like Figure 1-3 As shown, the utility model provides a locking device for a rotary kiln roller ring, comprising a limiting flange ring 2, a sleeve ring 3 and a connecting ring 4 coaxially sleeved on the roller ring body 1, the connecting ring 4 is fixedly welded to the roller ring body 1, the limiting flange ring 2 is fixed on the end wall of the connecting ring 4, both end walls of the sleeve ring 3 abut against the limiting flange ring 2, and the limiting flange ring 2 is connected to the end wall of the sleeve ring 3 through a force transmission pin 8.

[0018] The rolling ring body 1 is fixedly mounted on the rotary kiln, and the sleeve 3 is mounted on the middle of the outer circumference of the rolling ring body 1. The sleeve 3 is driven to rotate by the driving wheel at the bottom, and then the rolling ring body 1 and the rotary kiln are driven to rotate by the sleeve 3, thereby realizing the production of the rotary kiln. The connecting ring 4 is coaxially fixed and welded at both ends of the outer circumference of the rolling ring body 1, and the limiting flange ring 2 is welded to the end wall of the connecting ring 4, and the opposite side walls of the two limiting flange rings 2 are respectively attached to the two end walls of the sleeve 3, and the position of the sleeve 3 is limited by the two limiting flange rings 2. The original connection hole on the limiting flange ring 2 is used to open a hole on the end wall of the sleeve 3, and the opening corresponds to the connection hole. By connecting the force transmission pin 8 in the opening and the connection hole, it is ensured that the limiting flange ring 2 rotates with the sleeve 3.

[0019] like Figure 1-3 As shown. A triangular-shaped reinforcing rib 5 is connected between the outer side of the connecting ring 4 and the end wall of the limiting flange ring 2. The reinforcing ribs 5 are evenly distributed on the connecting ring 4 at equal angles. By connecting the reinforcing ribs 5 between the connecting ring 4 and the limiting flange ring 2, the reinforcing ribs 5 are arranged at equal intervals and evenly distributed throughout the limiting flange ring 2, providing stable support for the limiting flange ring 2 and ensuring its strength.

[0020] like Figure 3 As shown, in order to ensure the stability of the installation of the force transmission pin 8, a connecting hole for installing the force transmission pin 8 is opened on the end wall of the collar 3, and the connecting hole and the force transmission pin 8 are clearance-matched. The end wall of the force transmission pin 8 is welded to the limiting flange ring 2.

[0021] As a preferred embodiment of the present invention, in order to ensure stable transmission between the collar 3 and the limiting flange ring 2, the force transmission pins 8 are distributed at equal angles around the axis of the rolling ring body 1.

[0022] like Figure 2 and Figure 3 As shown. The connecting ring 4 is provided with a mounting groove, within which a force transfer block 6 is mounted. The force transfer block 6 is fixedly connected to the outer wall of the roller body 1. The end wall of the collar 3 is provided with a connecting groove for inserting the end of the force transfer block 6. The connecting groove is air-planed on the end wall of the collar 3. The connecting ring 4 is pre-delimited with a mounting groove. The end of the force transfer block 6 is then inserted into the connecting groove and welded to the roller body 1. The force transfer blocks 6 tightly clamp the collar 3 from both ends to prevent axial movement of the collar 3.

[0023] As a preferred embodiment of the present invention, the cross-section of the force transmission block 6 is T-shaped, the connecting groove is a T-shaped groove, and the outer wall of the force transmission block 6 is aligned with the inner wall of the connecting groove. The tight fit between the force transmission block 6 and the connecting groove ensures that the torque of the ring 3 rotation is effectively transmitted to the roller body 1, driving the roller body 1 to rotate synchronously.

[0024] like Figure 2 and Figure 3 As shown, in order to further improve the stability of the force transmission block 6 and prevent the axial movement of the collar 3, an oblique rib 7 is provided at one end of the force transmission block 6 away from the collar 3, and the oblique rib 7 is connected to the outer wall of the raceway body 1.
