Overview
The DSH series conical spiral belt mixer consists of a conical cylinder, a stirring device, and a transmission mechanism. The stirring device includes a central spiral shaft and a stirring spiral belt that is tightly attached to the inner wall of the cylinder. This machine is suitable for mixing powders and granular materials with high hygiene requirements, as well as for mixing materials with viscous fluids or materials mainly composed of thick, wet, and paste. Widely used in chemical, pesticide, dye, pharmaceutical, feed, fertilizer, metallurgy, mining
Working principle
The stirring device of a conical spiral belt mixer is usually composed of a central spiral shaft and two outer spiral belts that match the inner wall surface of the cylinder. When rotating, the outer spiral belt spirals upwards along the inner wall of the cylinder to lift the material. Due to the different linear velocities at various points on the surface of the spiral belt, the material undergoes irregular convection, shear, mixing, and diffusion under its action, forming a comprehensive composite motion. The spiral blades on the mixing shaft lift and throw out the central material during operation. Part of the thrown out material enters the spiral belt, and at the same time, the part of the material thrown out by the spiral belt is absorbed into the spiral envelope of the spiral blades and lifted. Repeat this process repeatedly to achieve uniform mixing of materials in a short period of time.
Equipment features
◆ Suitable for mixing powdery, granular, slurry or viscous substances, and has a wide range of uses.
◆ The mixing effect is strong. The wall-attached spiral belt and inner spiral simultaneously lift or compress the material to form a swirling material flow, which is suitable for mixing powdery or slurry materials with poor fluidity.
◆ The mixing process is relatively gentle, does not destroy the material particles, and has a low degree of fragmentation.
◆ The discharge is clean and almost all materials can be discharged.
Structure characteristics
◆ The reducer directly drives the mixing device to rotate, with smooth operation, compact structure and small footprint;
◆ There is no transmission mechanism in the cylinder to prevent lubricating oil from leaking and contaminating materials;
◆ The gap between the outer screw and the container wall is very small, which can prevent materials from adhering;
◆ The inner surface of the equipment is treated to eliminate dead corners.
Additional (Extended) Function
◆ According to process requirements, it can be professionally designed and manufactured according to positive pressure or vacuum state standards;
◆ Equipped with jacket or coil to meet multiple functions such as mixing, stirring, vacuum drying, etc.;
◆ The cylinder head is designed with a head structure according to user requirements, which is pressure-resistant and beautiful;
◆A variety of sealing devices are available: standard packing seal, skeleton seal, mechanical seal
◆ Discharge valve: plum blossom displacement valve, ball valve, butterfly valve and gate valve are available;
◆ Install a spray device with CIP online rotating cleaning spray ball for equipment cleaning;
◆ Add a shredding device to crush polymers to meet process requirements.
