Abstract
The utility model discloses a heated air circulation hot shears furnace. The heated air circulation hot shears furnace comprises a furnace body with an insulating chamber, a burner used for producing high-temperature gas, a combustor which is fixedly arranged above the furnace body, a passageway used for communicating the insulating chamber and the combustor, a heat circulating fan arranged inside the combustor and an air blast groove formed in the passageway. After the burner produces the high-temperature gas, the high-temperature gas and cool air inside the insulating chamber are mixed by the heat circulating fan and then enter the air blast groove. A certain pressure is formed by the high-temperature gas inside the air-blast groove, and then the high-temperature gas is blasted into the insulating chamber. The heated air circulation hot shears furnace has the advantages of being fast in heating, uniform in rod temperature and low in energy consumption.
Description
Technical field
The utility model relates to a kind of hot shearing furnace of hot air circulation.
Background technology
The hot shearing furnace (hot shearing furnace that is called for short hot air circulation) of the long excellent hot air circulation of many rods is one of requisite equipment during Extrusion Process of Aluminum Alloy Profile is produced.Its major function is that oval aluminium casting rod heating is cut into segment, gives extruder and extrudes.Hot air circulating system is the key core parts of the hot shearing furnace of hot air circulation, and this system quality directly affects hot shearing furnace heating effect and the energy consumption of hot air circulation.
The hot shearing furnace of traditional hot air circulation comprises body of heater with moist closet, for generation of the burner of high-temperature gas, burner directly is connected with moist closet, the high-temperature gas (〉=650 ℃) that burner produces directly enters moist closet, cause aluminium bar to melt fracture, cause the wasting of resources, and energy consumption is higher, other has partial design is that circulating fan directly is blown into jet-air slot with high temperature air, and the easy like this rod temperature of causing is inhomogeneous or because furnace pressure is too high causes the hot-air flight and reduce hot shearing furnace service life.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of hot shearing furnace of hot air circulation is provided, and heating, fast, excellent temperature is even, energy consumption is low.
For achieving the above object, the technical solution of the utility model has provided a kind of hot shearing furnace of hot air circulation, comprise body of heater with moist closet, for generation of the burner of high-temperature gas, also comprise the combustion chamber that is fixedly installed on described body of heater top, be communicated with described moist closet and the first passage of described combustion chamber, the thermal circulation fan that is connected with described combustion chamber, the second channel that is connected with described thermal circulation fan, with the jet-air slot that described second channel is connected, described jet-air slot is positioned at described moist closet.
As preferably, be provided with refractory brick in the described combustion chamber.
As preferably, described burner is burner.
As preferably, the thermal circulation fan of described thermal circulation fan for being made by the 310S material.
As preferably, the setting of sliding mutually along rotational axis line direction and described combustion chamber of described thermal circulation fan.
Advantage of the present utility model and beneficial effect are: after burner produces high-temperature gas, thermal circulation fan with high-temperature gas with enter jet-air slot after cold air in the moist closet mixes, high-temperature gas forms certain pressure in jet-air slot after, spray in the moist closet, heating, fast, excellent temperature is even, energy consumption is low.

Among the figure: 1, moist closet; 2, body of heater; 3, burner; 4, combustion chamber; 5, first passage; 6, thermal circulation fan; 7, jet-air slot; 8, refractory brick; 9, second channel.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, a kind of hot shearing furnace of hot air circulation, comprise body of heater 2 with moist closet 1, for generation of the burner 3 of high-temperature gas, also comprise the combustion chamber 4 that is fixedly installed on described body of heater 2 tops, be communicated with described moist closet 1 and the first passage 5 of described combustion chamber 4, the thermal circulation fan 6 that is connected with described combustion chamber 4, the second channel 9 that is connected with described thermal circulation fan 6, with the jet-air slot 7 that described second channel 9 is connected, described jet-air slot 7 is positioned at described moist closet 1.
As shown in Figure 1, be provided with refractory brick 8 in the described combustion chamber 4.By 4 interiorly refractory brick 8 being set so that heat insulation effect is better in the combustion chamber, reduce energy consumption.
Without diagram, described burner 3 is burner.Burner is mainly used in diesel oil or combustion of natural gas are formed high-temperature gas, and burner 3 can also be combustor.
Without diagram, the thermal circulation fan 6 of described thermal circulation fan 6 for being made by the 310S material.Durability is better.
Without diagram, the setting of sliding mutually along rotational axis line direction and described combustion chamber 4 of described thermal circulation fan 6.Be that thermal circulation fan 6 adopts plug-in connection with combustion chamber 4, be convenient to maintenance, maintenance, maintenance etc.
Operation principle: enter jet-air slot 7 with the high-temperature gas of burner 3 generations and by the gases mixing in the moist closet 1 in first passage 5 flowing in combustion chambers 4 through second channels 9 by thermal circulation fan 6, in the certain malleation of jet-air slot 7 interior formation, evenly spray to the aluminium bar in the moist closet 1.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
