Abstract

The invention relates to a positive-negative-pressure dual-purpose anti-explosion feeding device. The positive-negative-pressure dual-purpose anti-explosion feeding device comprises a hopper, a rotarymechanism assembly, a motor and a main drive gear, wherein the bottom of the hopper is equipped with a separating plate; an unloading hole is formed in a separating plate body of the separating plate; the rotary mechanism assembly comprises a rotary barrel body; an upper connecting plate is mounted in the upper opening of the rotary barrel body; a lower connecting plate is mounted in the lower opening of the rotary barrel body; a middle gear ring is arranged on the side wall of the rotary barrel body; a middle barrel is positioned on the center of the rotary barrel body, and a plurality of material tubes are arranged around the middle barrel; flanges are mounted on the upper connecting plate and the lower connecting plate; the separating plate is connected with the flange on the upper connecting plate through a bolt; the flange on the lower connecting plate is fixedly connected with an unloading plate through a bolt; a second middle hole is formed in the center of the unloading plate;an unloading hole is further formed in the unloading plate; a rotary joint passes through the second middle hole and a first middle hole; the output end of the motor is equipped with a main drive gear; and the main drive gear is engaged with the middle gear ring. The positive-negative-pressure dual-purpose anti-explosion feeding device is simple in structure, is safe and reliable in operation, and realizes positive-pressure feeding and negative-pressure vacuum feeding.

Description

technical field [0001] The invention relates to a positive and negative pressure dual-purpose explosion-proof feeding device, which belongs to the technical field of ferrous metallurgy and nonferrous metallurgy equipment. Background technique [0002] In the field of metallurgy and non-ferrous metallurgical equipment, especially the feed materials of reducing smelting furnaces such as blast furnaces, gas generators, rotary kilns, copper-lead smelting furnaces, etc., it is not desirable for the gas in the furnace to leak from the feed port. In other words, it is not desirable for the air to enter the smelting furnace together with the materials, and mix with reducing gases such as coal gas, hydrogen, methane, and flammable gases in the furnace to prevent explosions and other dangers. [0003] Nowadays, this kind of feeding method basically adopts the method of feeding with double material bell, and now the method of feeding without material bell has been developed, but the me...
