Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, and more specifically to a more durable slag cooler rotary joint. Background Art

[0002] Slag cooler, also known as slag cooler, is a device used to cool high-temperature materials. It is mainly composed of a cylinder, a slag inlet box, a slag outlet box, a power transmission device, a chassis and an electrical control system. The cylinder and the partition frame often adopt a water-cooled wall structure, and slag guide plates are welded on the inner wall of the cylinder and the partition frame. The working principle of the slag cooler is mainly realized through a cooler and a conveying device. When the high-temperature slag enters the cooler through the feed port, cooling water or air will be sprayed on the slag to cool it to a certain temperature. The cooled slag is then conveyed to the discharge port to complete the entire cooling and conveying process.

[0003] Slag coolers are widely used in high-temperature industrial fields such as steel smelting, cement production, and chemical industry, and can handle high-temperature flue gas, high-temperature slag, high-temperature melt, etc. In production equipment such as furnaces, kilns, furnace materials, and cement production lines.

[0004] When the existing slag cooler is in use, due to the poor production site environment and the large amount of impurities and dirt in the circulating medium, the sealing ring of the existing product is easily damaged by friction and cut by the impurities, resulting in sealing failure and leakage. The service life is generally short, which is not conducive to use. Utility Model Content
