The invention provides three schemes, wherein the specific scheme of the scheme I is as follows: the utility model provides a force automatic discharging device of high temperature, including installing the scum pipe assembly in the furnace bottom, the scum pipe assembly includes two section at least scum pipes, the scum pipe on top is connected with the furnace bottom, the scum pipe material that is connected with the furnace bottom adopts high temperature resistant wear-resisting material, the scum pipe bottom of bottommost is equipped with and unloads the sediment valve, the top overcoat of every section scum pipe is the bottom of last section scum pipe, every section scum pipe cross sectional area increases 60% -120% than last section scum pipe, the top surface of every section scum pipe is higher than last section scum pipe bottom surface by a take a definite time and is equipped with annular shrouding, be equipped with an annular air distribution plate between every section scum pipe bottom and the lower section scum pipe inner wall, be equipped with a plurality of wind holes on the air distribution plate, the lateral wall of every section scum pipe is located between air distribution plate and the annular shrouding, every air inlet outer end is equipped with a distributor, all distributor connections are on a total air pipe, be equipped with solenoid valve and maintenance valve on the total air pipe outer end connection compressed air source.
The invention relates to a pneumatic slag discharging valve, which comprises a valve and a cylinder, wherein the opening and closing actions of the valve are controlled by the cylinder.
The wind holes are zigzag and are arranged on the outer circumference of the air distribution plate.
The second scheme is basically the same as the first scheme in structure, and is different in that the wind holes are arc-shaped and are arranged on the outer circumference of the air distribution plate.
The third scheme is basically the same as the first scheme in structure, and is different in that the wind holes are circular and are arranged in the middle of the air distribution plate.
The working principle of the invention is as follows: when slag is required to be discharged, the slag discharging valve is opened, the electromagnetic valve is opened, compressed air flows through each distribution air pipe from the main air pipe to reach between each air distribution plate and the annular sealing plate, and the compressed air forms downward jet air flow through the air holes to forcedly purge the slag downwards, so that slag discharge is facilitated; and closing the overhaul valve when overhaul is needed.
Compared with the prior art, the invention has the following advantages: the compressed air is used for forcedly discharging slag, so that the probability of blocking the slag discharge pipe is greatly reduced, the overhaul frequency is reduced, the production efficiency is improved, the labor intensity is reduced, and the safety is improved.
