Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to Fig. 1, a kind of roasting sand device for quartz sand, comprise and being contained on support and the roasting sandbox body 4 of downward-sloping setting, the angle of inclination of roasting sandbox body 4 is 20 °-60 °, roasting sandbox body 4 output terminal bottom-hinged is on support, be fixedly connected on support by inclination angle riser 6 bottom roasting sandbox body 4 input terminus, inclination angle riser 6 can be motor-driven screw rod, when needing the angle of the roasting sandbox body 4 of adjustment, only needing to promote or reduce screw rod can make the input side of roasting sandbox body 4 promote or reduce, thus regulates the angle of inclination of roasting sandbox body 4.
Be provided with at least two silica tubes 8 side by side in roasting sandbox body 4, the internal diameter of silica tube 8 is 150-250mm, thus increases roasting sand ability.The two ends of silica tube 8 pass roasting sandbox body 4 respectively, and the silica tube 8 in roasting sandbox body 4 is wound with heater coil 9, and heater coil 9 is tungsten gold carbon fiber heating coil 9.Not only heating is fast for tungsten gold carbon fiber heating coil 9, and steep temperature excursion can be made suddenly to fall, and saves energy reaches 20%.
Be provided with adiabator layer between silica tube 8 and roasting sandbox body 4, adiabator layer is made up of high temperature resistant brick layer 13, alumina balls molding sand layer 12, the cotton layer 11 of silicic acid and light thermal-insulation brick layer 10 from inside to outside successively.Four layers of insulation make furnace heat not leak, and have both saved energy-conservation, have which in turn improved Working environment.
Silica tube 8 outside roasting sandbox body 4 two ends is respectively equipped with silica tube rotating mechanism; Silica tube rotating mechanism preferably includes the support roller 3 be set on silica tube 8, and support roller 3 is fixedly connected with support by rotary caster frame 5.
Be provided with feeder at the input side of roasting sandbox body 4, feeder comprises hopper 1, and hopper 1 can be self-feeding bucket, and be provided with material feeder 2 below hopper 1, material feeder 2 is electromagnetism self-feeder, and material feeder 2 connects with silica tube 8 respectively.
During use, the quartz sand that water content is higher is poured in hopper 1, escapes to material feeder 2 from hopper 1 lower end, and hydrophite sand is obtained fully loose releasing out by conglomeration shape by material feeder 2, thus in the smooth and easy silica tube 8 entering roasting sandbox body 4.Silica tube rotating mechanism drives silica tube 8 to rotate simultaneously, thus makes quartz sand heating temperature even.Roasting sandbox body 4 tilts certain angle, and such silica tube 8 rotates can by the quartz sand limit baking in it, while make the quartz sand of oven dry skid off to the output of silica tube 8.
Present invention achieves by the conversion of external heat to interior heating, heat energy is made full use of, and make manual operation change power operation into, improve benefit, saved the energy, improved environment, improve the quality of product, achieve the raising of economy, society, environment comprehensive benefit.
