Background technology
In recent years, the fuel rod processed by the stalk of each Plants is subject to the extensive concern of new forms of energy industry.The recycling of this biomass material is not only avoided directly burning the pollution caused air, can provide again a kind of novel clean energy resource, very large to protection of the environment contribution.
In to the processing of biomass material, needing the material to pulverizing to carry out drying and processing, controlling moisture wherein, meeting the processing humidity requirement of the products such as later stage fuel rod.Drying mode conventional now has tiling to dry, heats in room and dry, or by modes such as heating using microwaves, heating removing moisture is carried out to placement material, these methods all exist drying time for a long time, powder is heated uneven etc. shortcoming, needs a kind of novel drying unit to solve the problems referred to above.
Summary of the invention
A kind of solar energy powder for drying device, it is characterized in that: comprise solar energy air heat collector, utilidor, air-introduced machine, charging aperture, spiral drying, separator, air-introduced machine is arranged on the utilidor of heat collector hot air outlet, charging aperture is arranged on the utilidor between air-introduced machine and spiral drying, spiral drying base is connected with motor, control drying rotates, and separator bottom material outlet connects conveyer belt to material storing room.
Heat collector connects an independently control system, measures according to the humidity of charging and discharging, and the time length that the power of illumination regulates hot-air to pass into, and the rotating speed of spiral drying also regulates accordingly according to aforesaid condition.
Spiral drying inwall is provided with unconnected spiral iron plate, tilts to form helical form, keep at a certain distance away around inwall between flight along the direction that drying rotates; In the direction operated along spiral drying, all drainage piece is installed between every two panels spiral iron plate, drainage piece is perpendicular to spiral drying inwall, and drainage piece is a slice, two panels or more, can be mounted to straight line and arrange or in pairs linea angulata formula arranges during two panels drainage piece.
The embowment of drainage piece upper end, highly can be identical with spiral iron plate height, or higher than the height of spiral iron plate; Both height can carry out appropriate design according to the drying internal diameter of needs of production, raw material input amount etc.
In the present invention, the optimum length of spiral drying is 12-15 rice, and spiral iron plate every continuous print two panels spacing is paid the utmost attention to as 10-20 centimetre.
When the entrainment of warm air of heat collector material powders enter drying time, along with the rotation of drying, powder and hot-air mix along flight and rotate, powder material in motion pauses the several seconds after running into drainage piece, be scattered along the camber line of drainage piece upper end and come, along with rotating spiral iron plate, drainage piece of falling next circle, whole process constantly repeats, effectively extend the time of contact of powder and hot-air, fully drying is carried out to powder; By the humidity measurement to spiral drying outlet material, the running of whole system can be controlled easily, the final material obtaining humidity and meet production requirement.
Advantage of the present invention:
1, adopt solar thermal collector to add hot-air, economize energy, be conducive to environmental protection, avoid the danger of the material that ignites due to stove heating;
2, entrainment of warm air powder through spiral drying, under the continuous effect of spiral iron plate and drainage piece, the time of contact of powder and hot-air is longer, ensure that powder is by abundant drying, avoids insufficient, that heated time the is short shortcoming of being heated in the past adopting the forms such as heating coil cylinder to bring;
3, whole drying course low energy, device structure is simple to operation, and drying efficiency is high.

Detailed description of the invention
Select in the sun-drenched morning, air collector 1 to be opened, start when the temperature of hot air outlet reaches about 80 degree to start spiral drying 4, drying 4 arranges two drainage pieces 42 in the middle of every two the spiral iron plates 41 in the direction of rotating, and paired linea angulata formula arranges; Rice straw powder is added from charging aperture 3, start air-introduced machine 2 simultaneously, powder and hot-air mixing are discharged in spiral drying 4, entrainment of warm air powder and is rotated along spiral iron plate 41, pausing under the obstruct of drainage piece 42 after the several seconds is distributed on spiral iron plate 41 and drainage piece 42 again, whole process makes powder fully and hot air, fully dry; Be discharged to separator 6 through the powder of spiral drying 4 to be separated, the powder in separator monitored, is just transported to apotheca when reaching requirement, does not meet the requirements of, continue transported to charging aperture 3 again dry.
