I. Potassium Xanthate Kneading Dryer--Overview of Equipment

The drying process of sodium xanthate is divided into three main processes: synthesis, granulation and drying. In each process, the semi-finished materials in the process are in contact with the air, and some organic volatile substances are emitted into the air. , causing local air pollution. The existing drying equipment is mainly a double cone dryer, which mainly uses dry xanthate particles, but the double cone dryer is not suitable for drying yellow powder. The reason is that the outer cylinder shape of the double cone dryer is the upper and lower cones, and the gravity is used. The material moves up and down. During the rotation of the cylinder, the powdery material is unevenly distributed inside, which affects the drying effect. A part of the material will adhere to the inner wall of the cylinder, affecting the heat conduction effect, and some of the materials stick to the block shape, which is not easy to dry, and finally forms a defective product. In addition, a large amount of dust will block the vacuum suction port, and the drying time is lengthened, affecting yellow. The quality of the finished product.

The left and right lateral movements of the material are formed by the rotation of the left and right teeth at different angles. The powdery material is not easy to agglomerate, the material is turned and heated evenly, and some of the block materials are also chopped by the molars and adhered to the cylinder. The material is also scraped off by the molars to create an efficient drying effect. In addition, the specially designed vacuum dust removal structure increases the brine cooling jacket, and the powder material quickly cools down when it enters the vacuum outlet, reducing the probability of adsorption on the filter screen. Because the upper and lower vacuum filter nets are spared, the filter is replaced at the same time as each shift, and the operation time is not affected. The structure is simple, the maintenance is convenient, the failure rate is low, the sealing performance is good, the production efficiency is high, and no gas and dust are volatilized.
