Description of drawings
Accompanying drawing is the heat wind circulation heating equipment structural representation, and among the figure: (1) is that logistics pipeline supporting seat, (2) are that burner hearth, (3) (4) produce pipeline, (12) for logistics produce pipeline guide rail, (13) for hot air reflux pipeline, (14) be backflow air inlet nozzle for infrared radiation type combination metal heater plate, (11) for logistics for drop accumulation bleed valve, (10) for thermal circulation fan, (9) for volume damper, (8) for the poly-net of stainless steel drop condensation, (7) for air-out circulating line, (6) for Pt100 temperature sensor, (5).
The specific embodiment
The utility model adopts the infrared radiation type mode of heating, the heating thermal source of above logistic production line 11, forming the passageway type by left and right sides heating plate 10, the configuration hot air circulating system, material on the logistic production line heats through the passageway, both sides by streamline or drying process is handled, the top, passageway is provided with airflow reflux passage 5, the return flow line is provided with the poly-net 6 of drop stainless steel, U type collector tube and drain valve 9 are with the damp vapour-liquid body of discharging accumulation, hot reflux gas refluxes hot-fluid again through pipeline 13 by Hot-flow fan 8 and to inject burner hearths through air inlet nozzle 14 and carry out the circulating reflux heating after humidity discharging; The structure of Hot-flow fan adopts and axial flow blower structure roughly the same: the metal wing wheel is housed in blower fan, and the outer motor of the rotating shaft of metal wing wheel and pipeline links to each other, guarantees air-flow in the pipe interior circulation and do not leak, and the interior temperature of pipeline does not influence the operation of motor yet.One or several this type of passageway type heat cycles device can be set to satisfy the requirement on the logistic production line on the logistic production line to different material production heating, and can fully save the energy, between each section, all take to be provided with heat-resisting way every curtain, furnace temperature to each section is carried out isolated controlling, prevents that the furnace temperature of each section from interfering with each other.
The drop condensation gathers the Double-level Reticulated that net 6 adopts the stainless steels braiding, cooling after gas that contains aqueous vapor and filter screen collision, and its condensed water drops along the mesh grid gathering and discharges tracheaes to tapping valve 9 backs, and the aperture of stainless steel mesh grid is 300～800 orders; The diameter of metal wing wheel is 300～450mm, and material is aluminium alloy or stainless steel; Operating temperature in the pipeline is 60～300 ℃, and the power of single face heating plate is 1Kw, highly is 250mm, and length is 450mm, and thickness of slab is 25mm.
The passageway width bits 200～350mm of logistic production line;
Infrared radiation type combination metal heater plate 10 has taken into full account the technological requirement on the logistic production line, consider from health, protection against the tide, the anti-erosion, employing is placed on electrical heating wire in Φ 10mm～Φ 12mm stainless steel tube, fill quartz sand in the pipeline space, play insulating effect on the one hand, prevent gas cyaniding or corrosion on the electrical heating wire contact logistic production line on the other hand, pipe end seals and electrical heating wire is drawn by the insulation porcelain bead.The stainless steel tube that will contain electrical heating wire curves U type or S type and casts in the flat aluminum alloy, electrical heating wire is drawn by the insulation porcelain bead, constituted a whole heating plate, whole oxide treatments is carried out to form infrared emanation and to utilize alumite to completely cut off the erosion of external environment condition in this heating plate outside.This heater, not luminous during its work, so there is not the light loss consumption, adopting miniature bimetal release type temperature controller heater to be close on the aluminium alloy heating plate simultaneously installs, be connected in series with the electrical heating wire circuit, the control point of temperature controller is 160 ± 5 ℃, so the ceiling temperature on the aluminium alloy heating plate will be controlled at the temperature about 160 ℃ all the time, prevents to cause accident because of temperature control.
Passageway fire box temperature control on the logistic production line detects fire box temperature by the Pt100 temperature sensor 3 that is located in the burner hearth, convert the output of 4～20mA normalized current to through temperature transmitter, this output connects numeral and shows adjuster, adjuster has the function that drives the SSR solid-state relay, behind the external SSR solid-state relay, adjuster will reach the requirement of stable regulation and control fire box temperature according to the power that the temperature that technological requirement sets is directly controlled electric boiling plate.
Fire box temperature control also can detect the burner hearth leaving air temp by the Pt100 temperature sensor 4 that is located in the wind pipe, convert the output of 4～20mA normalized current to through temperature transmitter, this output connects digital governer, adjuster output drives the SSR solid-state relay, and reaches stable regulation burner hearth leaving air temp and then can reach the requirement of better controlled fire box temperature according to the power that the temperature that technological requirement sets is directly controlled electric boiling plate.
Employing bilateral in air-supply return flow line is blown simultaneously and is accelerated the heating rate of heating object, and makes burner hearth produce the mixed flow state, makes fire box temperature even; The bilateral air outlet adopts tiltedly carves type wind pushing nozzle 14 structures, and the bicker degree that is fit into that enters the burner hearth place that refluxes is 25～75 °, nozzle opening 15～25mm, and width is consistent with heating plate, and nozzle wind velocity is 0.8～3.5m/s.
Air-supply passage is made up of blower fan 8, control valve 7, air supply duct 13, air-supply mouth, air-out pipeline 5.
Whole air-supply arrangement is outer coated with insulation material, and insulation material can use asbestos layer, mineral wool or perlite to cover.
