The inclination angle on described inner core and overcoat and ground is 10 degree.
On described overcoat cylinder, be installed with bull gear, bull gear is through reductor and motor, gear drive rotation.
A top of the trellis at described overcoat two ends is provided with support roller, and support roller rotates and contacts with overcoat drum surface.
Described inner core adopts stainless steel to make; Overcoat adopts carbon steel material to make.
Operation principle of the present utility model is:
The utility model is dried ore in sand form and is adopted rotary dryer, flue gas and material indirect heat exchange, dryer inner core adopts tubulation, outer casing inner wall is longitudinally welded groove, on overcoat cylinder, fill bull gear, install whole device inclined 10 degree left and right, inner core two ends independent support, overcoat independent support, through reductor, the rotation of gear drive overcoat bull gear, need the ore in sand form of drying to enter from dryer is high-end, when overcoat rotates, ore in sand form spreads down above groove takes inner core to, fall between tubulation, moisture in ore in sand form is discharged from dryer top by thermal evaporation, ore in sand form is finally discharged from dryer afterbody.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the utility model is dried electric smelting zirconium and is comprised the inner core and the overcoat that are obliquely installed with rotary dryer, ore dressing material enters from overcoat position higher-end charging aperture, from overcoat position compared with low side discharging opening Natural excrement, reasonable in design, material is little by cylindrical shell resistance, operates steadily, easy to operate; Be connected with smoke-intake pipe road in compare Di one end, the position of inner core, be connected with smoke pipeline in compare Gao one end, the position of inner core, utilize electric arc furnaces fume afterheat and material indirect heat exchange, reduce the consumption of coal, save coal resources, in increasing economic efficiency, also contribute to energy-conserving and environment-protective.
2, structurally, the inclination angle on inner core described in the utility model and overcoat and ground is 10 degree, and inner core adopts tubulation structure, and outer casing inner wall is vertically arranged with groove; In the time that overcoat rotates, ore in sand form enters by dryer is high-end, takes inner core top to spread down through groove, falls between tubulation, and the moisture in ore in sand form is discharged from dryer top by thermal evaporation, and ore in sand form is finally discharged from dryer afterbody; Total is reasonable in design, and ore in sand form can fully be heated in dropping process between tubulation, product drying good uniformity, and heat utilization efficiency is high, and drying efficiency is also high simultaneously.
3, to sum up, the utility model is dried electric smelting zirconium rotary dryer reasonable in design, and mechanization degree is high, make full use of electric arc furnaces fume afterheat dried material, increase economic efficiency and energy-conserving and environment-protective, and ore in sand form can fully be heated in dropping process between tubulation, uniform drying is good, and material operates steadily, easy to operate, heat utilization efficiency is high again, and drying efficiency is high, and output is also high, fault is few, and maintenance cost is low, low in energy consumption, and applied widely, therefore, be very suitable for promotion and implementation.
