General calcining furnace, the calcining burner hearth of roasting flask device are provided with silica glass boiler tube or stainless steel boiler tube, due to the high cubical expansivity of quartz sand ore in temperature-rise period, while causing discharging, get stuck and silica glass boiler tube or the spalling of the stainless steel boiler tube problem such as pop.
In order to solve the calcining of above-mentioned continuity, calcine inhomogeneous and get stuck, the associated problem such as booster, aspect quartz sand calcining, carried out research practice, as the patent No.: the roasting assembly of 201220511981.2 1 kinds of purifying quartz sands, disclose in a kind of calcining furnace burner hearth and be divided into more than two hot-zone, and each hot-zone arranges independently temperature controlling system, to guarantee the temperature equalisation of quartz sand calcining.But get stuck, the defect problem of booster, solution is not provided.Now also there is the technology that adopts rotary kiln or rotary oven calcining quartz sand, but the method needs more complicated transmission component, equipment investment is large, running cost is high, quartz sand ore only occupies less volumetric spaces in burner hearth, and heat utilization rate is low, adds the irregular large on temperature impact in stove of inlet amount, cause calcining inhomogeneous, impurity component is removed not exclusively.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, efficient energy-saving and quartz sand ore vertical calcining furnace that can continuous production process.
The utility model is made up of body of heater, globars heating tube, silica glass boiler tube, controlling box, discharging plug and hydraulic ram.In body of heater, central position is provided with silica glass boiler tube, in silica glass boiler tube periphery, globars heating tube is installed, and at body of heater, controlling box is installed outward, in silica glass boiler tube bottom, discharging plug is installed, and discharging plug is connected on hydraulic ram.The cylindrical tubular body that the silica glass boiler tube that in body of heater, install central position is hollow; Globars heating tube is vertical array in silica glass boiler tube peripheral circumferential, is uniformly distributed; Discharging plug is one cylindrical, its top is wedge-like structure, inclined-plane and horizontal plane angle are set within the scope of 35 °-55 °, and in discharging plug cylindrical peripheral face and silica glass boiler tube, all cylinders are connected for moving, and discharging plug is fixedly connected on hydraulic cylinder piston rod; Power supply control, temperature detection and regulation and control, signal detecting and regulation device are installed in controlling box.
Principle of work of the present utility model is: operation control box makes hydraulic ram promote discharging plug along moving to the position concordant with silica glass boiler tube bottom, discharging plug bottom surface on silica glass boiler tube inwall, discharging plug is blocked silica glass boiler tube infraoral completely, add quartz sand ore from silica glass boiler tube upper end open, the heating of globars heating tube power supply is connected and regulated to operation control box, in the time that in burner hearth, quartz sand ore temperature progressively rises, quartz sand ore volume in silica glass boiler tube progressively expands, quartz sand ore is subject under the action of gravity of silica glass boiler tube internal upper part quartz sand ore to transmitting bulging force below to discharging plug in burner hearth, cause hydraulic ram oil pressure to raise, pressure sensitive device in controlling box starts hydraulic cylinder piston rod retraction, drive discharging plug to move down, when silica glass boiler tube bottom quartz sand ore temperature to 800 is during degree Celsius to 900 degrees Celsius of scopes, discharging plug continues to be displaced downwardly to silica glass boiler tube lower port place, because the upper surface of discharging plug is an inclined-plane, form an opening with silica glass boiler tube lower port intersection, the quartz sand ore of having calcined falls from opening part, the size of opening is transmitted to operation control box by temperature height induction in stove, control hydraulic cylinder piston rod lifting, drive the size that moves up and down to regulate opening of discharging plug, in the time of temperature sense parameter stability, discharging plug fixes in a fixed position, along with the continuous supply of charging, the continuous discharge of quartz sand ore of having calcined, to guarantee the uniformity consistency of calcining and to realize continuity calcining operation.In normal calcination process, lower furnace portion is opened wide, and the thermal expansion force that quartz sand ore heats up, along with the quartz sand ore of having calcined falls from opening part, and is released.
