Abstract

The utility model relates to an energy saving and materials saving fuel (gas) heating stove, which belongs to the field of the industrial stove. The utility model is characterized in that a stove cavity is divided into a high temperature area and a heating area; the stove cavity is communicated with a smoke chamber by a flue; the smoke chamber is communicated with the high temperature area of the stove cavity through a smoke-extracting device and a smoke gas mixer. The utility model changes the structure of the flue and adopts the closed loop flow to cause the oil gas to be burned fully, the energy source can be saved, and the environmental pollution can also be reduced. The integration of the stove cavity is changed into a separate structure to reduce the affinity of the oxygen for metals, and metal materials which are heated can also be saved.

Description

Energy saving fuel (gas) heating stove

The utility model belongs to the industrial furnace field, is used for quenching, annealing, heating of metal material etc.

At present, domestic general industry has through, single chamber or two chamber with the body of heater of heating furnace, and slot type etc., structure in the stove is that top is stove hall, nozzle, and flue divides upper flue and lower flue, and the bottom is a flue collector, this flue directly leads to chimney, its shortcoming is: 1. fuel oil can not fully burn, and cigarette enters the Nature through flue from chimney, contaminated environment; 2. fire and the metalwork in the stove hall strengthened the affinity of oxygen to metal under same atmosphere pressures, and the oxide layer of metalwork is increased, and waste material.

The purpose of this utility model provides a kind of fuel oil energy and fully burns, and has saved the energy, has avoided the pollution of environment, reduces oxide layer in the METAL HEATING PROCESS process, is heated energy-saving material-saving fuel oil (gas) heating furnace of metalwork with saving.

The technical scheme that realizes the utility model purpose is, the stove hall is divided into upper and lower two parts by demixing zone, the upper strata is the high-temperature region, lower floor is the thermal treatment zone, and the temperature difference reaches about 200 ℃ between the high-temperature region and the thermal treatment zone, because the high-temperature region gaseous pressure is less than the thermal treatment zone, oil gas, the flue gas of the thermal treatment zone are risen on the high-temperature region, thereby oxygen is to the affinity of metal in the reduction thermal treatment zone, and oxide layer is reduced, and has saved heated metal material; There is flue to be communicated with between stove hall and the smoke-box, there is flue to be communicated with between flue and the fume extractor, is fixed with cigarette and Air mixing device on the fume extractor, have flue to be communicated with between the high-temperature region of blender and stove hall, thereby make the cigarette that from the stove hall, comes out be circulated back to the stove hall, burn once more through flue.

Partition layer in the utility model is that symmetry is built out two fins on the inwall of stove hall, the position of burner be arranged on the demixing zone center line or under.

The utility model has changed the structure of flue, adopts closed loop to flow, and makes oil gas obtain abundant burning, thereby has saved the energy, has reduced environmental pollution; Change stove hall integrative-structure into the branch body structure, make to produce a pressure reduction in the stove hall, lowered the affinity of oxygen, the oxide layer of metal in heating process reduced, be heated metal material thereby saved to metal.

Fig. 1 is the utility model embodiment glowing furnace master cut-away view;

Fig. 2 is Figure 1A-A cut-away view;

Fig. 3 is Figure 1B-B cut-away view.

Be that embodiment describes structure of the present utility model in detail below with the accompanying drawing.

Stove hall 5 is divided into by demixing zone 13, two-layer down, the upper strata is high-temperature region 11, lower floor is the thermal treatment zone 12, demixing zone 13 adopts protruding block method, and promptly symmetry is built out two fins on the inwall of stove hall 5, and two fins can be contour, can not wait yet, burner 9 is fixed on the sidewall of stove hall 5, can on demixing zone 13 center lines or under, also can be with high, the position of demixing zone 13 in stove hall 5 and the position of burner 9, decide according to heated metal material and size, cut glowing furnace, the digonous height together of demixing zone 13 as steel, burner 9 is fixed on the demixing zone 13, with closely contact seamlessly between demixing zone 13 upper surfaces, as shown in Figure 1, be connected to air blast 10 on the burner 9; There is flue to be communicated with between stove hall 5 and the smoke-box 4 that is located at stove hall 5 lower ends, this flue is to be communicated with the upper flue 2 of stove hall 5 and the mouth 3 that advances on the smoke-box 4 respectively by the flue in the air preheater 1 in body of heater 14 outsides, there is flue to be communicated with between smoke-box 4 and the fume extractor 7, leave the outlet flue 6 that is communicated with fume extractor on the smoke-box 4, be fixed with cigarette and Air mixing device 8 on the fume extractor 7, blender 8 is communicated with the high-temperature region 11 of stove hall 5 by flue, shown in Fig. 2,3; Cigarette in the stove hall 5 arrives in the smoke-box 4 of furnace bottom after air preheater 1 preheating from upper flue 2, by fume extractor 7 cigarette in the smoke-box 4 is extracted out again, burn once more by the high-temperature regions of sending in the stove hall 5 after cigarette and air mixer 8 mixing 11, circulation successively, thus oil is fully burned.
