Technical Field
The utility model relates to a pressure-equalizing and diffusing maintenance pipeline for material tank maintenance; belonging to the field of equipment fault maintenance.
Background
Bell-less charging refers to a system for realizing charging by using a furnace top charging device. The bell-less top is used for bell-less top of small blast furnace with working volume above 250m3 and the bell-less feeding system only has bell-less top capable of distributing the material to any point on the material surface, no matter what charge (pellet, sinter, ore, coke, direct reduced iron, formed coke, powder) is used, the bell-less top can accurately distribute any required material type.
The bell-less furnace top is combined with the tank for feeding, the furnace top is provided with two pressure equalizing and bleeding systems which are independent and unified, when one system has equipment failure and needs to be overhauled, the other system needs to stop running, and the production needs to be stopped for processing.

fig. 2 is a schematic structural diagram of the present invention.
In the figure, 1 is a charging bucket, 2 is a pressure equalizing pipeline, 3 is a blow-off pipeline, 4 is a pressure equalizing main pipeline, 5 is a pressure equalizing valve, 6 is a blow-off valve, 7 is an eye valve, and 8 is a pressure equalizing main butterfly valve.
Detailed Description
In order to make the purpose and technical solution of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
As shown in fig. 2: a pressure-equalizing and diffusing maintenance pipeline for the maintenance of charging buckets comprises two groups of charging buckets 1, wherein the top of each charging bucket 1 is provided with a pressure-equalizing pipeline 2 and a diffusing pipeline 3; a pressure equalizing valve 5 is arranged on the pressure equalizing pipeline 2, and a bleeding valve 6 is arranged on the bleeding pipeline 3; the pressure equalizing pipeline 2 and the diffusing pipeline 3 are respectively provided with an eye valve 7. And an eye valve 7 is respectively arranged on a feed end pipeline and a discharge end pipeline of the pressure equalizing valve 5 on the pressure equalizing pipeline 2.
An eye valve 7 is arranged on the discharge end pipeline of the diffusion valve 6 on the diffusion pipeline 3. The pressure equalizing pipeline 2 is collected to the pressure equalizing main pipeline 4, and a pressure equalizing main butterfly valve 8 and an eye valve 7 are arranged on the pressure equalizing main pipeline 4.
When equipment failure appears in one side material tank pressure equalizing system and needs to be overhauled, in order to not only not influence normal production of blast furnace but also ensure to overhaul safe and reliable, the pressure equalizing main butterfly valve of the failed material tank is only needed to be closed, the inlet and outlet eye valves of the failed material tank are closed simultaneously, reliable cutting off of the failed equipment is realized, the outlet eye valve of the pressure equalizing blow-off valve is closed simultaneously, the problem that coal gas discharged by the normally produced material tank is mixed into the material tank for overhauling is avoided, thereby realizing online equipment overhauling, normal material distribution work of the other side material tank pressure equalizing system is avoided, and production interruption and shutdown are avoided.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
