Technical Field

The invention relates to the technical field of drying equipment, in particular to a steel belt scraper device.

Background

Drying of liquids has many applications in industrial production and in daily life. Especially in the industries of chemical industry, wastewater treatment and the like, substances in the solution have high recovery value. Therefore, the drying of the liquid has important significance for industrial production, wastewater treatment and daily life of people.

In the case of drying a liquid, there are various methods for drying, and the drying of a mixed liquid is mainly carried out by spraying, flash evaporation, direct drying, or the like. Spray drying works best for mixed liquids, but costs the highest, with direct drying being the lowest and more widely used.

When the mixed liquid is dried by using a direct drying method, the adhesion degree of the dried residue to the conveying belt is different according to different characteristics of the residue. Meanwhile, the high temperature makes the residues more easily attached to the surface of the conveying belt; the accumulation of residue reduces the drying effect of the freshly added liquid and the residue is not easily collected. Therefore, in the process of drying the liquid, the residues on the surface of the conveying belt are removed in time, the residues are collected, and meanwhile, the drying efficiency can be improved.

At present, the direct drying device who commonly uses is drum-type drying equipment, and to the higher solution of concentration, drying effect is better, but drum-type drying equipment has certain requirement to the concentration of solution and the adhesion characteristic of solution, and to the solution that solution concentration is lower or adhesion characteristic is not good, drying effect is not good. Meanwhile, the cost of large-scale drum-type drying equipment is high. For drum-type drying equipment, steel band drying equipment can make by the dry solution tiling to the steel band surface, and the tiling thickness can be adjusted according to steel band functioning speed and solution dripping speed. For different solutions, different spreading thicknesses can be selected to achieve the desired drying effect. Therefore, the steel strip drying equipment has lower requirements on the concentration and the adhesion property of the solution and has wider application range.

When the steel strip drying equipment works, the solution is spread on the steel strip, and after the solution is dried, residues can be attached to the surface of the steel strip. However, because the thickness of the steel strip is thin, the residue cannot be directly scraped by the fixed scraper structure, otherwise the steel strip is easily damaged by the scraper.
