A pressure ring for a submerged arc furnace with a cleaning port

Abstract

A pressure ring for a submerged arc furnace with a cleaning port, comprising two pressure semi-rings, at least two cleaning ports are provided on the side wall near the bottom of the semi-rings, and a sewage discharge device is arranged on the cleaning port. The sewage discharge device includes a sleeve and a gland. The sleeve is embedded in the cleaning port, and is welded on both sides along the contact surface. An O-ring is arranged on the contact surface between the lower end of the gland and the inner hole of the sleeve in both axial and radial directions, and the O-ring is embedded in a notch provided on the gland. Every time you need to clean the dirt, just unscrew the back cover to work, reducing the heat stop time and reducing the maintenance workload of workers. Even for enterprises with better cooling water quality, after a long time, using the cleaning port to remove the dirt in dead corners can make the waterway smooth and improve the service life of the equipment.

Description

technical field [0001] The invention belongs to a pressure circulating water cooling component for submerged arc furnace equipment and belongs to the submerged arc furnace equipment manufacturing industry. Background technique [0002] At present, the traditional pressure ring cooling system used in our country is a half ring with water in and out all the way. In order to ensure the service life and normal operation, the water cooling system is usually required to be demineralized water. However, in most small and medium-sized private enterprises, the water treatment facilities are relatively simple, and the hardness of the water cannot be lowered. In a high-temperature environment, after two months of operation, the pressure ring will be fouled and deposited on the corners, resulting in poor water flow. Smooth, so that the internal parts of the pressure ring are burned due to high temperature, the manufacturer has to cut a hole at the bottom of the pressure ring every two m...

Problems solved by technology

However, in most small and medium-sized private enterprises, the water treatment facilities are relatively simple, and the hardness of the water cannot be lowered. In a high-temperature environment, after two months of operation, the pressure ring will be fouled and deposited on the corners, resulting in poor water flow. smooth, so that all parts in the pressure ring are burned due to high temperature, the manufacturer has to cut a hole at the bottom of the pressure ring every two months, remove the scale and then repair the welding

Such repeated maintenance has caused a lot of waste to the enterprise

In addition, the current pressure ring is mostly made of stainless steel, and it is not easy to cut or weld during the maintenance operation under high temperature in the furnace, which makes the maintenance more difficult
