Abstract
The utility model discloses a box type Teflon sintering furnace direct combustion heating system comprising a furnace body, a circulating wind pipe, a circulating blower, a gas combustion machine, and a hot and cold air mixing chamber. The circulating blower is arranged at a top of the furnace body. The hot and cold air mixing chamber is arranged in the furnace body and under the circulating blower. The circulating wind pipe is installed on the furnace body in a sintering furnace. The gas combustion machine is installed on the furnace body and is connected with the hot and cold air mixing chamber. According to the utility model, compared with a system before improvement, heating and temperature rise are fast, heat utilization efficiency is high, more energy is saved, structure is simplified and compact, investment cost of equipment is reduced, and an occupying space of the equipment is saved.
Description
Technical field
The utility model relates to the direct-fired heating system of a kind of box Teflon sintering furnace.
Background technology
At present the direct-fired heating system of existing box Teflon sintering furnace adopts the outer mixing chamber of stove, outside stove, heats, and combustor is installed in outside the stove, air outside stove, heat after inside and outside the stove circulation airduct deliver in the stove.The thermal efficiency is low, and the heating-up time long (rise to 400 ℃ and need 60min approximately), outer mixing chamber of stove and stove outer circulation airduct can dissipate a part of heat, and thermal losses is bigger, the entire equipment complex structure, and floor space is bigger.
Summary of the invention
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model provides a kind of box Teflon sintering furnace direct-fired heating system; It comprises: body of heater, circulation airduct, circulating fan, gas combustion machine, cold and hot air mixing chamber, and said circulating fan is arranged on the body of heater top, and said cold and hot air mixing chamber is arranged on body of heater inside; Under the circulating fan; Said circulation airduct is installed on the inner body of heater of sintering furnace, and said gas combustion machine is installed on the body of heater, connects cold and hot air mixing chamber.
Further, said cold and hot air mixing chamber manufacturing materials is the heat-resistance stainless steel plate.
Further, be provided with return air inlet bottom the said cold and hot air mixing chamber.
Further, said circulation airduct is provided with hot-blast outlet near the body of heater bottom.
The beneficial effect of the utility model: the utility model heating system adopts the direct combustion mode to heat; The gas combustion machine is directly installed on sintering furnace inside; The backwind tube that former sintering furnace is inner changes heat-resisting SUS304S corrosion resistant plate into; Be used for direct combustion heating mixing chamber, directly in stove, accomplish a whole set of heating process.Compared to original technology, direct-fired heat temperature raising fast (be warming up to 400 ℃ and only need 40min), efficiency of utilization is high; Can reach 99%, cold and hot air mixing chamber and circulation airduct are transformed built-in, and thermal losses is little; More energy-conservation, the occupation of land space of saving equipment reduces the investment of devices cost.
Description of drawings
Fig. 1 is the direct-fired heating system structural representation of a kind of box Teflon sintering furnace of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify:
The utility model provides a kind of box Teflon sintering furnace direct-fired heating system; It comprises: body of heater 1, circulation airduct 2, circulating fan 3, gas combustion machine 4, cold and hot air mixing chamber 5, and said circulating fan 3 is arranged on body of heater 1 top, and said cold and hot air mixing chamber 5 is arranged on body of heater 1 inside; Circulating fan 3 times; Said circulation airduct 2 is installed on the inner body of heater 1 of sintering furnace, and said gas combustion machine 4 is installed on the body of heater 1, connects cold and hot air mixing chamber 4.
Further, said cold and hot air mixing chamber 4 manufacturing materials are the heat-resistance stainless steel plate.
Further, said cold and hot air mixing chamber 4 bottoms are provided with return air inlet 6.
Further, said circulation airduct 2 bottoms are provided with hot-blast outlet 7.
Gas is in cold and hot air mixing chamber 4 burnings; Hot-air after the burning mixes with the wind that the circulation airduct 2 that return air inlet 6 gets into returns, and sends into circulation airduct 2 by circulating fan 3 again, gets into burner hearth 8 by hot-blast outlet 7; Make temperature rising in the burner hearth 8; Heated parts so circulates repeatedly, and is temperature required up to workpiece is heated to.
Compared to prior art, the utility model is through built-in with cold and hot air mixing chamber and the transformation of circulation airduct, and designs simplification is compact, and heat temperature raising is fast, and thermal losses is little, and efficiency of utilization improves, and equipment cost reduces, and equipment takes up an area of the space and reduces.
