Description

Technical Field

[0001] This utility model relates to the field of roller installation technology, specifically a roller installation device for a roller kiln. Background Technology

[0002] A roller kiln is a continuous firing kiln, a tunnel kiln that uses rotating rollers as the transport vehicle for the ceramic blanks. Ceramic products are placed on many closely spaced horizontal refractory rollers, and the rotation of the rollers transports the ceramics from the kiln head to the kiln tail. Each roller has a small sprocket at its end, driven by a chain. For smooth and safe transmission, the chain is often divided into several groups for drive. Rollers at low temperatures are made of heat-resistant nickel-chromium alloy steel, while those at high temperatures use high-temperature resistant ceramic rollers (such as corundum ceramic rollers or silicon carbide rollers).

[0003] When installing rollers in a roller kiln, two installers are usually required to lift one end of the roller, move it to the installation position, and then put it down. Since the rollers are generally made of ceramic, they are fragile and heavy. Moving and placing the rollers manually is time-consuming and laborious, resulting in low installation efficiency. Therefore, a roller installation device for roller kilns is proposed to solve the above problems. Utility Model Content
