Double cone drying equipment SZG-5000

Device description

The double cone rotary vacuum dryer is widely used for drying powder and granular (including bulk) materials in industries such as chemical, pharmaceutical, food, dye, powder metallurgy, etc.

The middle of the dryer tank is cylindrical, and the two ends are conical. The top of the cone is equipped with inlet and outlet ports (also serving as manholes), and the tank is divided into three layers inside and outside. The heating medium of the middle jacket can be steam or circulating hot water, and the insulation layer is medium alkali ultra-fine glass wool, which consumes very little energy; The inner layer is filled with materials and dried under vacuum conditions. The materials are flipped and heat is obtained through the wall, accelerating the drying process. This avoids the phenomenon of surface yellowing of heat sensitive materials during drying and greatly shortens the drying time of the materials, which is only about 2/3 of the drying time required for similar materials in a vacuum oven, improving labor productivity; Specially suitable for drying easily oxidizable, flammable, explosive materials and heat sensitive materials; When it comes to materials that do not damage their shape, materials that strictly limit metal ions, and materials that require the recovery (or destruction of toxicity) of volatile substances (or toxic substances), their superiority can be better demonstrated.

The vacuum suction head of a conventional double cone dryer is a single head and does not rotate with the tank body. Due to the heavy vacuum suction head and the lack of concentricity between the vacuum tube and the rotating shaft during installation, the sealing packing between the vacuum tube and the tank body arm seat often wears out too quickly, resulting in a large gap. A small amount of material enters the tank body arm seat and comes into contact with the carbon steel part. If the material is contaminated with iron ions, it will be vacuum sucked into the tank during the drying of the next batch of materials, causing a batch of materials to be scrapped, with serious consequences. At the same time, the entry of materials into the self arm seat of the tank can also cause wear on the vacuum tube and damage to the sealing components (rotary joints or machine seals) at the tube end. Therefore, our engineering and technical personnel have addressed this drawback through technical breakthroughs and adopted a new structure to solve this technical difficulty. Designed a technology that synchronizes the rotation of the vacuum tube with the tank body, which is equipped with a vacuum head. This avoids the problem of product contamination caused by residual materials or worn-out sealing ring materials due to the wear of the cylinder and vacuum tube by other manufacturers' equipment.
