Dihydrate iron phosphate rotary flash dryer

onePrinciple

Spin Flash DryerIn the development process, the focus is on maximizing its dispersion, that is, increasing the surface area per unit volume of wet material to accelerate heat and mass transfer processes. The required air is purified through an air filter, heated by a heater, and enters the mixing, crushing, and drying chamber through the bottom annular gap tangent, generating a spiral upward airflow; Wet materials are continuously and quantitatively added to the dryer through a spiral feeder. The dried products are carried out of the dryer with hot air through the upper outlet pipe, and collected into the material bin through a cyclone separator and a bag filter. The exhaust gas is extracted by a induced draft fan and then enters the water foam dust collector for purification.

twoCharacteristics

1) The bottom of the drying chamber is equipped with an inverted conical structure, which continuously expands the cross-section of the hot air flow from bottom to topHigh speed results in low gas velocity in the upper part, allowing both large particles in the lower part and small particles in the upper part to be in a good fluidized state,The inverted cone structure also reduces the length of the mixing shaft cantilever, increasing the reliability of operation;

2) The upper part of the drying chamber is equipped with a grading ring, which mainly serves to block materials with larger particles or that have not been dried from dryingDrying room can effectively ensure product particle size and moisture requirements;

3) The hot air inlet at the bottom of the cone is equipped with a jacket protection to prevent the material from overheating and deteriorating due to contact with high-temperature air;

4) The material disperses rapidly in hot air with short drying time, making it particularly suitable for drying thermosensitive materials such as pesticidesDryness;

5) Continuous operation allows for self control of feeding amount, hot air temperature, and product particle size within a certain range,So as to ensure the various indicators of the dried product;

6) The drying system is enclosed and operates under negative pressure, preventing dust leakage and protecting the production environment for safetyhygiene;

7) The equipment has a compact structure, occupies a small area, and integrates drying, crushing, and grading into one. It is a fluidized bed technology and rotaryThe combination of rotary technology, spray technology, and convective heat transfer technology greatly simplifies the production process and saves costsEquipment investment and operating costs.
