Abstract
The invention discloses suspension drying technology for materials and relates to drying technology, in particular to technology for drying dried materials in hot air stream in a suspension state. The implementation of the technology is suitable for drying a plurality of powder materials. The technology of the invention is mainly characterized in that: the dried materials can be suspended under the action of strong air stream, so that the following technical problems that: 1, the materials are close to one another and shield one another, so that surface heating is not uniform; 2, drying speeds of different individuals are different due to different geometrical properties of material individuals; 3, the dried materials need to be turned mechanically in a drying process; 4, successfully-dried materials are mixed with and cannot be separated from materials needing to be dried continually; and 5, the water content of the dried materials is inconsistent existing in the conventional general drying technology are solved.
Description
Affiliated technical field
The present invention relates to a kind of drying technology, exactly is can make by the oven dry material to be in the suspended state drying technology in thermal current.
Background technology
At present, in the drying technology flow process that drying technology field bulk material is adopted all is to be placed in the container at the netted end by the oven dry material or conveyer belt is sent into drying chamber and heated, and moisture is oozed out form steam from material to discharge drying chamber with moving air.The problem of its existence is: 1, storeroom is together adjacent, blocks mutually, and the surface is heated inhomogeneous; 2, owing to rate of drying difference between material individual geometry proterties Different Individual, influence the degree of drying quality; 3, being dried material will carry out machinery and stir in drying course; 4, dried the qualified material of being dried and mixed, can not separate with the quilt oven dry material that needs to continue oven dry.
Summary of the invention
The technology of the present invention makes the material of being dried that enters drying chamber be in suspended state under the effect of air blast, rise to quite height with the thermal current flow direction, along with the thermal current diffusion strength weakens, the material that need continue to dry drops to the circulation rising suspension of air blast territory, is dried qualified material and continues to finish whole drying course after rising enters cyclone separator and thermal current separates with more weak air-flow.Realize being reached the water content unanimity by the material after the oven dry.
Description of drawings
Accompanying drawing is a drying technology process principle figure of the present invention
1. hot-blast stoves rouse according to circumstances among the figure, 2. hot-blast stove, 3. hot air duct, 4. air blast, 5. hothouse, 6. conveying pipeline, 7. material separator, 8. material separator exhaust outlet, 9. material separator discharging opening, 10. what suspend is dried material, 11. charging aperture, 12. cold airflow air blasts, 13. electric energy heaters, 14. the cold airflow flashboard, 15. thermal current flashboards.
The specific embodiment
The technical solution adopted for the present invention to solve the technical problems is: by the accompanying drawing finding, the thermal current of hot-blast stove 2 conversions enters drying chamber 5 by hot air duct 3 under the effect of hot-blast stove air blast 1, entered drying chamber 5 by oven dry material 10 by charging aperture 11, dry under suspended state at material under the effect of cold and hot mixing air blast 4, weakened with air blast by oven dry wet feed suspension certain altitude, after falling back to drying chamber bottom chance air blast under the effect of gravity, suspend once more; The material of being dried is crossed conveying pipeline 6 with weak relatively air communication and is entered material separator 7, and steam is discharged by material separator exhaust outlet 8 after the feed separation of air and oven dry, and the oven dry qualified material is discharged by material separator discharging opening 9.When not needing cold airflow, cold airflow valve 14 is closed; When not needing thermal current, thermal current valve 15 is closed.Cold airflow air blast 12 and hot-blast stove air blast are all regulated current rate with the power supply frequency modulation method or are regulated hot and cold air proportion control drying chamber temperature.Special when being needed the higher temperature drying technology to handle by the oven dry material, power up and enable electric energy heater 13.
Claims (2)
1. a material suspended drying technology is characterized in that being dried material is in suspended state in whole drying course under the effect of air-flow thrust.
2. according to the material suspended drying technology of power general introduction 1 described a kind of thermal current, it is characterized in that making by the material suspended air blast of oven dry is to be formed by one cold airflow and back, one thermal current interflow, and its flow direction by the drying chamber bottom upwards.
