Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, specifically providing a rotary kiln tire resetting device. Background Technology

[0002] In the lime production section, the rotary kiln experiences relative sliding due to gaps between the tire and the stop block, as well as an 8-12mm gap between the tire and the pad. As the kiln operates for an extended period, these gaps widen, the stop block wears down, and eventually the tire shifts. Therefore, after a period of operation, the tire must be reset and the pad replaced. However, each tire reset using the old method is extremely time-consuming and requires significant manpower and resources.

[0003] Traditional methods require the rotary kiln to be fully lifted when replacing the tire, which not only requires a large investment of manpower and time, but also poses significant safety risks, such as an increased possibility of accidents due to equipment instability and operational complexity during maintenance.

[0004] Accordingly, there is a need in the field for a new rotary kiln tire resetting device to solve the above-mentioned technical problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of the relatively complicated replacement of the existing rotary kiln tire.

[0006] This utility model provides a rotary kiln tire reset device for adjusting and replacing the tire pad assembly of the rotary kiln cylinder. The reset device includes:

[0007] The stop block, the pulley pad assembly includes a pad and a pulley, the pad is sleeved on the outer wall of the cylinder; the outer wall of the pad is arranged to form a sliding groove structure, the stop block is slidably installed in each of the sliding groove structures, the stop ends of the stop block extend to both sides of the pad; the pulley is sleeved on the outer side of the pad;

[0008] An ejection mechanism is installed on the outer wall of the cylinder. The ejection mechanism includes a fixed frame and an ejector. Multiple fixed frames are arranged parallel to the pad on the outer wall of the cylinder. The ejector is fixedly installed on the fixed frame, and the ejection end of the ejector is aligned with the pad.

[0009] A roller support mechanism is located at the bottom of the cylinder and is connected to the pulley for driving and supporting the cylinder.

[0010] Based on the above configuration, this reset device achieves efficient reset and adjustment of the rotary kiln tire pad assembly through a clever combination of a stop block, an ejector mechanism, and a support roller mechanism. The stop block is slidably installed via a groove structure, ensuring precise positioning of the pads and stable support for the tire; the ejector mechanism provides a stable and powerful ejection force, facilitating rapid adjustment of the pad position; the support roller mechanism is connected to the pulley drive, providing both stable support for the kiln body and enabling effective rotation of the kiln body. The overall design is compact and highly functional.

[0011] In the preferred embodiment of the above-mentioned reset device, the stop end of the stop block is connected to the pad plate by a first fixing bolt thread.

[0012] Based on the above configuration, the stop end of the stop block is connected to the pad plate by the first fixing bolt thread, which can firmly fix the stop block and prevent it from loosening or shifting in the slide, thereby improving the stability and safety of the device operation.

[0013] In the preferred embodiment of the above-mentioned reset device, two first fixing bolts are provided between the stop end and the pad at each end.

[0014] Based on the above configuration, two first fixing bolts are installed between each end of the stop and the pad, which can further enhance the reliability of the connection, distribute the torque load, prevent the connection from loosening or the structure from being damaged due to single-point force, and improve the overall safety and service life of the device.

[0015] In the preferred embodiment of the above-mentioned reset device, the ejector is a jack and the fixing frame is a steel support.

[0016] Based on the above setup, using a jack as the ejector not only provides powerful ejection force but also allows for precise positioning of the pad by adjusting the ejection amount; the fixed frame uses a steel support, which has high structural strength and can withstand large loads, ensuring the safety and durability of the device.

[0017] In the preferred embodiment of the above-mentioned reset device, the jack and the steel bracket are connected by a second fixing bolt thread.

[0018] Based on the above configuration, the jack and the steel support are connected by a second fixing bolt thread, which provides a firm and detachable connection method. This facilitates installation and maintenance, and ensures the strength and stability of the connection, making it less prone to loosening during long-term use.

[0019] In the preferred embodiment of the above-mentioned reset device, two second fixing bolts are provided between each of the jacks and the steel bracket.

[0020] Based on the above setup, two second fixing bolts are installed between each jack and the steel support, which further enhances the strength and reliability of the connection, effectively distributes the force, ensures that the system can still work stably under high loads, and avoids equipment failure due to loose fasteners.

[0021] In the preferred embodiment of the above-mentioned reset device, the jack is a 50-ton jack.

[0022] Based on the above setup, a 50-ton jack is used, which can provide a large enough jacking force to cope with the large load requirements during the tire pad adjustment process, ensuring the reliability and efficiency of the operation, and can easily handle even heavy cylinders.

[0023] In the preferred embodiment of the above-mentioned reset device, the jacks are arranged in three sets at equal intervals.

[0024] Based on the above setup, three sets of jacks are evenly spaced, which can provide uniform and stable support and adjustment force to the tire pad, effectively avoiding deformation, displacement or damage caused by uneven force, improving operating accuracy and efficiency, and ensuring the safety of equipment operation.

[0035] The ejection mechanism is installed on the outer wall of the cylinder 1. The ejection mechanism includes a fixed frame and an ejector. Multiple fixed frames are arranged parallel to the pad 4 on the outer wall of the cylinder 1. The ejector is fixedly installed on the fixed frame, and the ejection end of the ejector is aligned with the pad 4.
