Drying equipment for sodium formate

Abstract

The invention discloses drying equipment for sodium formate. The drying equipment comprises a machine box, wherein a preheating chamber, a drying chamber and a material collecting chamber are sequentially distributed inside the machine box from top to bottom, a first-stage discharging opening is formed in the bottom of the preheating chamber, the preheating chamber communicates with the drying chamber through the first-stage discharging opening, supporting legs are fixedly mounted at the bottom of the machine box, and grooves are formed in the bottom parts of the supporting legs. According tothe drying equipment for the sodium formate, complete crushing is carried out by crushing teeth on the outer sides of a secondary crushing roller and a primary crushing roller, so that the caked sodium formate is prevented from falling into the inside of the preheating chamber, and the drying effect is improved; the sodium formate in the process of drying is turned over by an arranged material turning plate, so that the powdery sodium formate is fully dried, the drying speed can be accelerated, and the working efficiency is improved; and the sodium formate is conveyed to the inside of the preheating chamber by a guiding pipe, and a heat preservation cotton on the outer side of the guiding pipe can reduce the loss of heat, so that the temperature inside the preheating chamber is improved, the energy consumption is reduced while the working efficiency is improved, and the use is facilitated.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a drying equipment for sodium formate. Background technique [0002] Sodium formate, also known as sodium formate, is mainly used in the production of formic acid, oxalic acid and hydrosulfite, etc. Its structure is white granular or crystalline powder. It is hygroscopic and has a slight smell of formic acid. It is generally sealed and kept dry. Available in lined plastic bags and outer woven bags. [0003] Due to the high hygroscopicity of sodium formate, there is a phenomenon of agglomeration. The agglomerated sodium formate will be insufficiently dried during the drying process, thereby reducing the quality of sodium formate. At the same time, the drying time spent by sodium formate drying equipment is relatively long Long, low efficiency, at the same time, the gas discharged from the sodium formate drying equipment is directly discharged into the air, the heat insi...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of drying equipment of sodium formate, to solve the problem of insufficient drying in the above-mentioned background technology, thereby reducing the quality of sodium formate, while the drying time spent by the sodium formate drying equipment is longer now, and the efficiency is low, while sodium formate The gas discharged from the drying equipment is directly discharged into the air, the heat inside the gas cannot be fully utilized, the environmental protection is low, and it is not easy to use
