Blast furnace material distribution is the most important production link of blast fumance, and the stabilization of the cloth number of turns is even more the core of cloth, blast furnace cloth
The influence factor of feed ring number is a lot, and influence cloth number of turns stability has crude fuel granularity, furnace top pressure, two equal pressure etc., its
In two equal pressure due to being pressed using nitrogen, the fluctuation of nitrogen pressure and furnace top pressure directly affects the accurate of the cloth number of turns
Property, although fluctuation can be reduced by adjusting stream, due to furnace top pressure and the unstability of nitrogen pressure, the cloth number of turns by
To have a great influence, cause the bad stability of gas stream in the stove after the cloth number of turns is unstable, top pressure fluctuation increases, and the cloth number of turns is entered
One step is difficult to ensure that smooth operation of furnace situation can be on the hazard.
Utility model content
The utility model purpose is to provide a kind of device of the stable blast furnace roof material distributing number of turns, can be according to the fluctuation of top pressure
Material flow gate aperture is adjusted at any time, ensures the stability of the cloth number of turns, solves problem present in background technology.
The technical solution of the utility model is：
A kind of device of the stable blast furnace roof material distributing number of turns, comprising blast furnace, distributor chute, batch can, material valve valve plate,
Stream motor-driven valve, electric control valve, nitrogen pipeline, furnace top pressure detector, controller and batch can pressure detecting instrument, State of Blast Furnace
The top of body is provided with batch can and furnace top pressure detector, and the bottom of batch can is provided with the distributor chute stretched into blast furnace, batch can
Interior to be provided with material valve valve plate, material valve valve plate connects with the control of stream motor-driven valve, and batch can is provided with batch can pressure detecting instrument, nitrogen
Pipeline connects with batch can, and nitrogen pipeline is provided with electric control valve, the batch can pressure detecting instrument and furnace top pressure detector point
Do not transmit and connect with controller, controller connects with stream motor-driven valve and electric control valve control respectively.
Material valve valve plate in the batch can is located at the bottom of batch can.
The batch can pressure detecting instrument is located at the top of batch can.
Coal gas tedge is additionally provided with the top of the blast furnace.
Using the utility model, furnace pressure is measured by furnace top pressure detector, and is transferred to controller, controller
According to the blowing number of turns of upper batch of material, motorized adjustment valve opening is adjusted, ensures the stability of batch can pressure, and passes through the micro- of controller
Amount is calculated, and material flow gate is adjusted, and ensures the stabilization of the cloth number of turns.
The beneficial effects of the utility model are：Nitrogen amount is adjusted by electric control valve, ensures batch can pressure
Stability, while according to the blowing situation of upper batch of material, material flow gate is calculated and finely tuned, on the one hand ensure that batch can pressure
Power, it is unstable to avoid the cloth number of turns caused by pressure oscillation, still further aspect, also by the micro tune of material flow gate
Section, it is unstable to avoid the number of turns caused by crude fuel fluctuates.It is rational in infrastructure, it is easy to use, improve cloth number of turns stability.
