Abstract

The invention discloses a wet concentrate drying machine and aims to solve the problem that part of wet concentrate is burned by direct contact with flame in the drying process through an existing drying machine. According to the wet concentrate drying machine, a drying barrel is internally provided with a burning barrel with the inner portion being provided with perforated clapboards, and the material outlet end of a material adding pipe is made to stretch into the space between the burning barrel and the drying barrel, a burning mouth of a burning device is made to stretch into the inner portion the burning barrel from the front end of the burning barrel, thus the flame sprayed by the burning mouth can be isolated from the wet concentrate, and radiant heat and hot air flow are guaranteedto enter the drying barrel smoothly to dry the wet concentrate, the situation that part of the wet concentrate is burned by direct contact with the flame in the drying process is avoided, the dryingeffect can be guaranteed and the metal iron content loss in iron powder caused by the drying process is controlled within one percentage point, the iron powder product quality is guaranteed, and the production difficulty is lowered, so that acceleration of the production rhythm is facilitated.

Description

technical field [0001] The invention relates to a dryer, in particular to a wet concentrate dryer. Background technique [0002] At present, in the iron powder production process, water is used as the medium to grind and enrich iron-containing materials. The wet concentrate obtained by grinding has a high humidity, with a moisture content of 10-12%, while the moisture content of iron powder products is required to be 1%. the following. Since the iron powder is prone to agglomeration and oxidation during the stacking process, its moisture content is generally controlled below 0.15% in the production process, so it is necessary to use a dryer to bake the wet concentrate. The existing dryer includes a drying cylinder and a cylinder front cover and a cylinder rear cover respectively arranged on the front and rear ends of the drying cylinder. Both the cylinder front cover and the cylinder rear cover are rotatably connected with the drying cylinder. A feeding pipe and a burner a...
