Abstract

The invention relates to a safety shutoff value device for on-line interception of high-temperature fused slag. In the device, a value tank is fixed on a slag runner through a support I, and a support II is fixed above the value tank; a cylinder, a chain wheel assembly, a limit part and a fixed block are fixed on the support I; counter weight is connected with the cylinder; one end of a chain is connected to the counter weight, and the other end of the chain is connected to a valve plate; a part of a cooling water pipe is casted in the valve plate; and two paths of cooling water are formed on the valve plate, wherein one path of cooling water cools the upper part of the valve plate, and the other path of cooling water cools the lower part of the valve plate. If a driving system is in accident in the slag-taking process, the counter weight can directly elevate the valve plate after the valve position of a solenoid valve is regulated by hand. The safety shutoff value device for on-line interception of high-temperature fused slag provided by the invention is used for shunting off and taking slag in a mineral wool production process, and is capable of controlling the slag-taking amount in the slag-taking process so as to ensure the separation of iron and slag; and the service life of the valve plate is long, and the valve plate can also be timely elevated when equipment fails, thereby ensuring the smoothness of slag flow in the slag runner of a blast furnace.

Description

technical field

[0001] The present invention relates to the online slag extraction technology in the mineral wool production process, which is based on the device for receiving high-temperature slag by random flow control on-line in blast furnace (application number: 201120220612.3) and the adjustable baffle plate of the device for online access to high-temperature slag in blast furnace (application number : 201120220613.8), a technology that can realize the smooth up and down movement of the valve plate and fail-safe protection technology, especially relates to a safety shut-off valve device that intercepts high-temperature slag online. Background technique

[0002] As a by-product of blast furnace smelting, blast furnace slag has an important impact on the normal production process of blast furnace. Stable and reasonable slag quality not only lays the foundation for the stable operation of the blast furnace, can produce high-quality molten iron products, but also has a ser...
