Background technology
The powder materials such as glass sand are general in the middle of manufacturing process all will through technical process such as super-dry, high-temperature roasting, purifications.Because structure is simple, easy to make, maintenance cost is low, can work continuously, and rotary furnace is applied extensively at many industrial circles.At present, be all generally through type to the high-temperature process rotary furnace of the powder materials such as quartz sand, in operating process, material slides from high-end toward low side gradually along with the rotation of spherical hearth, can not well be scatter, material is heated uneven, dry and roasting effect is poor; When there being gas to participate in reaction, vapor solid contact is insufficient; When several material mixes, can not mix.Cause thermal effectiveness undesirable thus, constant product quality is poor, and performance indications are low.
Summary of the invention
For above problem, the invention provides a kind of roaster that can improve quartz sand thermal effectiveness under equal volume equal temperature newly, by improving the tubular type burner hearth of roaster main element, improve the corresponding performance of roaster, for reaching this object, the invention provides a kind of quartz sand tubular type high-temperature roasting furnace, the burner hearth of described high-temperature roasting furnace is wrapped with heating element heater, described burner hearth is rotated by rotating mechanism, described burner hearth separates into anterior quartzy lumen by circular bulkheads, the quartzy lumen in middle part and rear portion quartz lumen three lumens, the center drilling with burner hearth concentric shafts is had in the middle of described circular bulkheads, described circular bulkheads both sides are distributed with flight, described flight is parallel with the axle of burner hearth, described flight is angularly around the axle one week of burner hearth, the front opening of the quartzy lumen in described front portion is the powder material charging apertures such as quartz sand, the tail end opening of described rear portion quartz lumen is the powder material discharging openings such as quartz sand.
Further improvement of the present invention, in α angle between described burner hearth and horizontal plane, the burner hearth bottom of described high-temperature roasting furnace has angle regulator, by angle regulator control α angle size, described angle regulator is lifting screw or pad, burner hearth of the present invention is with certain inclination angle, and angle of inclination is by regulating the lifting screw being arranged on pedestal lower end or/and increase and decrease moat sheet regulates.
Further improvement of the present invention, had speed changer in described rotating mechanism, and the rotating speed of burner hearth of the present invention regulates by speed changer, to realize mass flow or/and the control of flow velocity.
Further improvement of the present invention, is fitted with breather pipe in the tail end discharging opening of described rear portion quartz lumen, while adding quartz sand from anterior quartz cavity pipe head end, can insert breather pipe realize ventilation operation from III pipe tail end and discharging opening.
Further improvement of the present invention, described heating element heats mode is Electric heating, described heating element heater is resistance wire or resistive band or Elema or Si-Mo rod, the present invention mainly adopts conventional Electric heating to heat, and concrete heating element heater can adopt resistance wire or resistive band or Elema or Si-Mo rod.
Further improvement of the present invention, described burner hearth, flight and circular bulkheads adopt heat proof material to make, and described heat proof material is quartz glass, and the higher general employing quartz glass of heat resistant requirements of the present invention is as the material of burner hearth, flight and circular bulkheads.
Further improvement of the present invention, overall through the high temperature anneal before described burner hearth uses, in order to ensure to need entirety through the high temperature anneal before heating effect burner hearth uses.
The feature of this technology is: after the powder such as quartz sand enter the burner hearth a slightly tilted, along with the slowly rotation of burner hearth a, progressively move down, and be constantly distributed on burner hearth a inwall in the process moved down, and dug by flight, scatter, thus disperseed fully, the steam through heating can be evaporated rapidly; When there being gas to pass into, the quartz sand be dispersed throughout fully contacts with atmosphere, and then improves refining effect.
Compared with prior art, there is following clear superiority:
1, avoid material in conventional art and slide the defect that can not be reversed, material is run more smooth, reduce material to the wearing and tearing of inboard wall of burner hearth simultaneously;
2, built-in flight plays turnover panel and stirring action, and pending material is fully disperseed, and improves the thermal efficiency;
3, when carrying out gasification to material and purifying, can ensure that gas-solid is on good terms and more fully contact, improve refining effect.
