Structure for quickly eliminating putty at bottom of weighing material tank

Abstract

The invention relates to a structure for quickly eliminating putty at the bottom of a weighing material tank. An airtight box is arranged at the bottom of the weighing material tank; a first barrel material hole is fixed on the wall of the weighing material tank and positioned at the bottom of the weighing material tank and is higher than the airtight box; a barrel material hole base is fixed on the outer wall of the weighing material tank and completely covers the first barrel material hole; a second barrel material hole communicated with the first barrel material hole is arranged in the barrel material hole base; and a barrel material hole cover is arranged on the barrel material hole base and seals the second barrel material hole. The invention realizes rapid treatment, indirectly reduces the blast furnace damping-down and slow wind time, ensures normal production, and simultaneously avoids gas poisoning and personnel burn accidents caused by blast furnace gas outflowing from a blast surface after the blast furnace damping-down, thereby ensuring good safety and no injury to processors.

Description

technical field [0001] The invention relates to the improvement of the structure of the weighing material tank, through which the material blocking phenomenon at the bottom of the weighing material tank can be quickly eliminated. Background technique [0002] The weighing material tank is installed under the feeding gate, which is used to store, transfer and weigh the charge, and realize the device of feeding under pressure. There are two types of weighing tanks: series tanks and combined tanks. It is one of the indispensable equipment for blast furnaces. [0003] When the weighing material tank is loaded, the lower sealing valve and the material flow regulating valve are closed to ensure the stability of the blast furnace top pressure. After filling the material (empty and full signals are given by the electronic scale), lock the bottom of the tank, close the upper sealing valve, and then equalize the pressure on the material tank (use semi-clean gas for the first equaliza...

AI Technical Summary

Problems solved by technology

The key is that there are other potential safety hazards while poking the material, mainly gas poisoning, or the possibility of being burned

Therefore, the existing measures to eliminate sticking and blocking materials not only take a long time, but also affect the normal production of the blast furnace, and pose a potential threat to the personal safety of maintenance personnel.
