Sodium hydrosulfite packaging method

Abstract

The invention relates to a sodium hydrosulfite packaging method which can be used for packaging sodium hydrosulfite automatically; therefore, the problem of large labor intensity is solved, the quantity of dust generated in the packaging process is reduced, and packaging errors of sodium hydrosulfite can be lowered. The sodium hydrosulfite packaging method comprises the following successive steps of: 1, automatically conveying sodium hydrosulfite by using a closed conveyer; 2, feeding the sodium hydrosulfite output by the closed conveyer in a sieving machine for sieving; feeding the sodium hydrosulfite output form the sieving machine in a second closed conveyer; 4, feeding sodium hydrosulfite output by the second closed conveyer in an automatic weighing mechanism for weighing; and 5, after weighing with the automatic weighing mechanism, feeding sodium hydrosulfite in a sodium hydrosulfite packaging barrel and automatically sealing the barrel.

Description

technical field [0001] The invention relates to a method for packaging sodium bicarbonate. Background technique [0002] As we all know, sodium hydrosulfite is a white self-flowing crystalline powder, which belongs to the 4.2 category of spontaneous combustion items, and is a strong reducing agent. It can spontaneously ignite at 250°C; heating or contacting an open flame will cause combustion; it will be oxidized and deteriorated when exposed to air; it will decompose and generate heat when exposed to a small amount of water or exposed to humid air, causing combustion and releasing toxic sulfur dioxide. Due to the above special properties of hydrosulfite, it is difficult to realize automatic packaging of hydrosulfate products. At the same time, due to the current production process of hydrosulfite, the small packages of 50Kg / bag of pyrolyte and 50Kg / bag of sodium formate are mainly used for manual batching, and pyrolyte and sodium formate are manually added to the batching ...
