Calcium carbide feeding device for acetylene generator

Abstract

The invention relates to a calcium carbide feeding device for an acetylene generator, and belongs to the field of acetylene gas production equipment. The device comprises a metering bucket, an upper feeding valve, an upper storing bucket, a lower feeding valve, a lower storing bucket and a vibrating feeder, wherein the metering bucket, the upper feeding valve, the upper storing bucket, the lower feeding valve and the lower storing bucket are sequentially connected through flanges from top to bottom; the lower storing bucket is in flexible connection with a feeding opening of the vibrating feeder; a discharging opening of the vibrating feeder is flexibly connected to the feeding opening of the acetylene generator; a dust removing opening and an air sucker are arranged on the metering bucket; the dust removing opening is connected to an air inlet of the air sucker; a nitrogen charging pipe and an air exhausting pipe are correspondingly arranged on the upper storing bucket and the lower storing bucket; a powder filtering bag is arranged on the lower storing bucket; air outlets of the air exhausting pipe and the air sucker are correspondingly connected to the powder filtering bag through hoses. According to the device, the calcium carbide powder produced in the feeding process can be filtered and collected through the powder filtering bag and prevented from directly entering air toaccumulate to cause damage.

Description

technical field [0001] The invention relates to the field of acetylene gas production equipment, in particular to a calcium carbide feeding device for an acetylene generator. Background technique [0002] The acetylene generator is the key equipment for the production of acetylene gas by the calcium carbide method. The working principle is to coarsely crush and finely crush the original block of calcium carbide. The crushed calcium carbide is weighed and sent into the weighing hopper, and then enters the upper storage hopper through the upper discharge valve. , and then enter the lower storage hopper through the lower unloading valve, and finally send it evenly into the acetylene generator by the vibrating feeder for hydrolysis reaction. During the feeding process, both the upper storage hopper and the lower storage hopper need to replace the air in the hopper with nitrogen to prevent a small amount of acetylene gas in the acetylene generator from entering and mixing with ai...
