Examples
Referring to fig. 1 and 3, an embodiment of the present application provides a heating furnace 100, including: the porous medium burner 10, the heat recovery device and the preheating section 30 and the heating section 40 which are connected in sequence;
the heating section 40 heats the material by means of the porous medium burner 10, and the heat recovery device can collect the flue gas of the heating section 40 and feed it to the preheating section 30 to preheat the material before heating.
Among them, the heating furnace shown in the aluminum bar heating system in fig. 3 is a top view heating furnace.
Further, the heating furnace 100 further comprises a heat-preserving section 50, the heat-preserving section 50 is connected to the heating section 40 and can receive the heated material, and the heating power of the heat-preserving section 50 is smaller than that of the heating section 40. The holding section 50 of this embodiment also provides thermal and convective heating of the material by the porous media burner 10.
The heat-insulating section 50 can eliminate the head-tail temperature difference of the bar 1000 and the temperature difference between the surface and the center of the bar 1000, and can reduce unnecessary energy consumption with lower power while playing the above-mentioned role.
Referring to fig. 1 and 2, in particular, the porous medium burner 10 is distributed on both sides of the heating section 40 and can release heat from both sides to the middle to heat the material in the middle of the heating section 40. In the present embodiment, the porous medium burners 10 on both sides in the heating section 40 are distributed side by side. Of course, the porous medium burners 10 of the insulation section 50 are also distributed side by side on both sides of the bar 1000.
Wherein fig. 2 is a left side view of fig. 1 with a partial section and with the following recycle centrifugal fan 21 hidden. As can be seen from the figure, the porous medium burners 10 on both sides are opposite to the central bar 1000, the bar 1000 is placed on the bar supporting wheel 60, and as the porous medium burners 10 heat the bar 1000 through heat radiation and heat convection, the bar supporting wheel 60 does not directly impact by flame and work at high temperature for a long time like a traditional single bar furnace, so that the service life of the bar supporting wheel is longer.
In addition, the heat-insulating layer in the hearth cannot be heated by high-speed flame, and the service life of the furnace is longer than that of a common single-rod furnace.
The porous medium burners 10 on both sides can concentrate heat in the middle to raise the temperature of the rod 1000 more quickly. The bar material is further designed into a structure distributed side by side, so that heat can be released to the bar material 1000 more intensively, and the heat efficiency is higher.
Referring to fig. 3, in order to make the fuel burn more sufficiently and further improve the thermal efficiency, the heating furnace 100 of the present application further includes a combustion-supporting assembly, the combustion-supporting assembly includes a combustion-supporting blower 80 and a combustion-supporting gas pipeline 81, and the combustion-supporting blower 80 provides combustion-supporting gas to the heating section 40 through the combustion-supporting gas pipeline 81. By providing the combustion-supporting gas, the porous medium combustor 10 can be ensured to combust the fuel more fully, and the thermal efficiency of the fuel is improved. The combustion-supporting fan 80 is a centrifugal fan, two combustion-supporting gas pipelines 81 shown in fig. 3 are communicated in the furnace body, and the combustion-supporting fan 80 can provide combustion-supporting gas for the heating section 40 and the heat preservation section 50 through the combustion-supporting gas pipelines 81.

The circulating centrifugal fan 21 is disposed in the preheating section 30 near the rod inlet end 101. It will be appreciated that, since the heating section 40 and the holding section 50 are in communication with the preheating section 30, when the circulating centrifugal fan 21 is operated, a certain amount of high temperature flue gas in the heating section 40 and the holding section 50 can be extracted and then switched to the preheating section 30 near the rod-entering end 101. Of course, the smoke tube 70 is disposed beside the preheating section 30, and when the smoke exceeds a certain amount, the smoke can be released, so as to avoid the influence of excessive smoke on the normal operation of the heating furnace 100. It should be noted that most of the high temperature flue gas of this embodiment is sent to the preheating section 30 for utilization, the flue pipe 70 is reserved mainly for timely discharging flue gas in case of excessive flue gas amount occasionally occurring, and the discharge amount is small at ordinary times, mainly for discharging the flue gas used up and discharging the flue gas during shutdown. When the circulating centrifugal fan 21 works, a part of redundant flue gas can be promoted to be discharged.

Further, the circulating centrifugal fan 21 can extract the flue gas of the heating section 40 and spray the flue gas onto the surface of the material in the preheating section 30 at a speed of 60-80 m/s. Through practice, the circulating centrifugal fan 21 can collect the high-temperature flue gas at about 600 ℃, and the high-temperature flue gas can be accelerated through pressurization. When the bar 1000 is an aluminum bar, the surface of the aluminum bar may be preheated to 250 ℃ under the spray of high temperature flue gas at a speed of 60-80 m/s.
The aluminum bar is preheated by utilizing high-temperature flue gas, then is heated by heat radiation and convection through the rows of porous medium burners 10 at the two sides, the aluminum bar can be heated to a specified temperature (about 460-480 ℃) in the heating section 40, and then the aluminum bar entering the heat preservation section 50 can be continuously heated by the rows of porous medium burners 10 at the two sides of the heat preservation section 50 by heat radiation and convection, so that the purpose of eliminating the head-tail temperature difference and the core-surface temperature difference of the aluminum bar is realized. Finally, the aluminum bar out of the furnace door mechanism 102 is fully heated to meet the temperature of the process requirement of the subsequent processing technology. For example, after the aluminum bar reaches the temperature, the aluminum bar can enter an extrusion process, and the temperature of the aluminum bar can ensure that the aluminum bar can be smoothly extruded into the required shape and size.

Compared with the traditional multi-rod furnace for heating air, the heating speed is higher under the condition of the same heating power.
The length of the heating furnace 100 is L, and L is more than or equal to 7395mm and less than or equal to 7400 mm. The length of the heating furnace 100 of the present embodiment is 7397mm, and it can be understood that the heating furnace 100 is shorter than a general heating furnace. But because the heating effect is good, under the condition of reaching the same heating speed, the length of the furnace body is shorter, and the field is saved more. If the length of the furnace body is consistent with that of the existing heating furnace, the heating speed is faster than that of the existing heating furnace.
The furnace body of the embodiment can be shorter, so that the disassembly and the movement are more convenient, and the practical application of enterprises is more convenient.
Simply speaking, the porous medium burner 10 can burn fuel more fully, the generated heat can be transmitted to the bar 1000 in the heating section 40 in the modes of heat radiation and convection heat transfer, the heating effect is better than that of a simple air heating mode, so that the energy of the fuel can be efficiently utilized, and further, the flue gas is collected by a heat recovery device, namely, the rest heat is recovered and is applied to the preheating section 30 to preheat the bar 1000, the energy of the fuel is further utilized, the heating efficiency of the bar 1000 is improved, and unnecessary energy waste is reduced.

By using the heating furnace 100, the whole aluminum bar heating system can improve the heating efficiency of the aluminum bar, improve the utilization rate of energy sources and reduce energy waste.
The rod pushing mechanism 200 and the rod discharging mechanism 300 may refer to an automatic rod pusher and a rod discharging device used in the existing aluminum rod heating furnace 100, the rod pushing device may sequentially push the aluminum rods into the aluminum rod heating furnace 100, and the rod discharging device is disposed outside the door mechanism 102 of the heating furnace 100, and may receive the heated aluminum rods, so as to facilitate the aluminum rods to enter into the operating device of the subsequent extrusion process. Specifically, the subsequent process operations and the operations of pushing and discharging the rod are not repeated.
Optionally, the aluminum bar heating system further comprises a bar storage mechanism 400, wherein the bar storage mechanism 400 is connected with the bar pushing mechanism 200 and is used for supplying the aluminum bars to the bar pushing mechanism 200. Store up excellent mechanism 400's aluminium bar can push away excellent mechanism 200 in proper order, then push the heating furnace 100 with the aluminium bar in proper order through push away excellent mechanism 200, and a plurality of aluminium bars keep the positional relationship of coaxial line, ensure that every aluminium bar can both be sent into heating furnace 100 according to accurate position.

And the surplus high-temperature flue gas in the heating section 40 is collected by the heat recovery device and fed back to the preheating section 30, so that the fuel can be fully utilized, and the heat efficiency is high.
