Abstract
The utility model provides a furnace entry linkage has furnace gate (2), is equipped with heating element 4 in furnace body (1), is equipped with circulating fan (5) at furnace body (1) top that resistance furnace with adjustable cooling rate, by furnace body (1) and furnace gate (2) constituteing, furnace body (1) to be equipped with chimney (6) at furnace body (1) top, its characterized in that: chimney (6) its flue bottom be equipped with electromagnetism dish valve (7), be equipped with the branch export on the flue on electromagnetism dish valve (7) upper portion, divide the export to be connected with pipeline (8) of draught fan (9), the flue top is equipped with filter mantle (10). The utility model discloses, convenient operation is simple, chimney through the addition and draught fan make the thermal treatment resistance furnace heat up, with constant temperature, cooling automatic control combines together, effectual control cooling speed has improved the quality of high thermal treatment work piece greatly, simultaneously can be fine prevent that waste gas from directly getting into the atmosphere, pollute the atmosphere.
Description
Technical field
The utility model relates to high temperature heat treatment furnace technical field, especially about a kind of rate of temperature fall trimmable resistance stove.
Background technology
Along with the development of modern science and technology, some product component heat treatment performance is required also more and more stricter, particularly cooling rate after tempering heat treatment is controlled there is strict demand.The product parts in past is lowered the temperature by body of heater naturally cooling after Q-tempering, and cooling rate is uncontrollable, and especially multi-portion heating furnace body cooling rate differs greatly; Current each enterprise is to the part of processing special purpose, and tempering heat treatment technique has strict demand to cooling rate, and must lower the temperature with certain speed, existing heat treatment furnace all cannot realize this requirement; Waste gas and the hot gas of raw a large amount of high temperature can be joined in addition when heating.These waste gas and hot gas were all directly enter in air in the past, and this not only pollutes environment, were also a kind of great wastes to resource.
Summary of the invention
For above deficiency, the purpose of this utility model there are provided a kind of rate of temperature fall trimmable resistance stove, by temperature in the even body of heater of the recirculation blower of furnace interior, electromagnetism dish valve during arrival temperature fall time on chimney is opened note and is opened, now start the induced draft fan be connected with chimney, impel furnace interior hot gas to discharge from throat fast by induced draft fan, then by the filter mantle of chimney top, hot gas is filtered, prevent waste gas from directly entering in air.
The technical solution of the utility model is achieved in the following ways: a kind of rate of temperature fall trimmable resistance stove, be made up of body of heater, fire door, furnace door lifting device, the burner hearth entrance of body of heater is connected with fire door, and fire door has controlled to coordinate with body of heater open/close by furnace door lifting device; Be provided with heating unit in body of heater, be provided with recirculation blower at body of heater top, and be provided with chimney at body of heater top; It is characterized in that: its stack base of described chimney is provided with electromagnetism dish valve, the flue on electromagnetism dish valve top is provided with a point outlet, and a point outlet is connected with the pipeline of induced draft fan, and flue top is provided with filter mantle.
Described body of heater is made up of bonnet, chassis, movable pulley, is provided with movable pulley bottom bonnet, and after chassis is fixing, bonnet has moved chassis by movable pulley and coordinated formation body of heater.
The filter mantle that described chimney top is installed is provided with multiple aperture.
The utility model, simply easy to operate, make that resistor furnace for heat treatment heats up by the chimney of addition and induced draft fan, constant temperature, cooling control to organically combine automatically, effectively control cooling rate, substantially increase the quality of high heat treated part; Well can prevent waste gas from directly entering in air simultaneously, air is polluted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 body of heater, 2 fire doors, 3 furnace door lifting devices, 4 heating units, 5 recirculation blowers, 6 chimneys, 7 electromagnetism dish valves, 8 pipelines, 9 induced draft fans, 10 filter mantles, 11 bonnets, 12 chassis, 13 movable pulleys.
Embodiment
Known by Fig. 1: a kind of rate of temperature fall trimmable resistance stove, is made up of body of heater 1, fire door 2, furnace door lifting device 3, and the burner hearth entrance of body of heater 1 is connected with fire door 2, fire door 2 is completed by furnace door lifting device 3 elevating control and coordinates with body of heater 1 ON/OFF; Heating unit 4 is provided with in body of heater 1, be provided with recirculation blower 5 at body of heater 1 top, body of heater 1 is made up of bonnet 11, chassis 12, movable pulley 13, is provided with movable pulley 13 bottom bonnet 11, after chassis 12 is fixing, bonnet 11 has moved chassis 12 by movable pulley 13 and has coordinated formation body of heater 1.And being provided with chimney 6 at body of heater 1 top, its stack base of chimney 6 is provided with electromagnetism dish valve 7, and the flue on electromagnetism dish valve 7 top is provided with a point outlet, and a point outlet is connected with the pipeline 8 of induced draft fan 9, and flue top is provided with filter mantle 10, and filter mantle 10 is provided with multiple aperture.Being filtered by filter mantle can well prevent waste gas from directly entering in air simultaneously, pollutes air.
During work, workpiece is placed in body of heater 1, and fire door 2 closes, and heating unit 4 works, and the electromagnetism dish valve 7 on heating initial stage chimney 6 is opened, and now can be got rid of the waste gas in stove by chimney 6, after Preset Time, electromagnetism dish valve 7 cuts out, recirculation blower 5 work of body of heater 1 inside makes body of heater 1 internal temperature even, open when in-furnace temperature arrives temperature fall time electromagnetism dish valve 7, the induced draft fan 9 be now connected with chimney 6 starts, recirculation blower 5 continuous firing, the inner hot gas of body of heater 1 is impelled to discharge from chimney 6 oral area fast by induced draft fan 9, filtered by filter mantle 10 pairs of hot gas at chimney 6 top again, prevent waste gas from directly entering in air, simply easy to operate, with induced draft fan 9, resistor furnace for heat treatment is heated up by the chimney 6 of addition, constant temperature, cooling controls to organically combine automatically, effective control cooling rate, substantially increase the quality of high heat treated part.
