Description

Technical Field

[0001] The utility model relates to a furnace, in particular to a furnace head assembly and a heating furnace. Background Art

[0002] The stove head includes a stove pipe for ventilation. Gas is introduced from one end of the stove pipe and discharged outward along the air holes on the outer side of the stove pipe. However, when in use, the gas output is usually larger near the gas inlet end of the stove pipe, while the gas output is smaller at a position far from the gas inlet end of the stove pipe. Since the gas output at different places on the stove pipe is uneven, the flame generated on the stove pipe is uneven, thereby affecting the effect of heating and baking food. Therefore, a stove head with better combustion effect is urgently needed. Utility Model Content

[0003] The utility model aims to provide a furnace head assembly and a heating furnace to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A stove head assembly comprises: a stove tube, one end of which is provided with an air inlet and the outside of which is provided with a plurality of air outlet holes; a spoiler connected to the outside of the end of the stove tube close to the stove tube where the air inlet is provided, the spoiler extending into the stove tube; a fireproof plate located above the stove tube, the fireproof plate being provided with a plurality of through holes.

[0006] This technical solution has at least the following beneficial effects: one end of the furnace tube is used for air intake, and fuel gas is input into the furnace tube from the air inlet. Since a spoiler is connected to the end of the furnace tube close to its air inlet, turbulence is caused when the fuel gas passes through the spoiler, thereby interfering with the fuel gas from directly discharging from the nearby air outlets. In this way, the fuel gas can be reduced from being directly discharged outward from the air outlet close to the air inlet, so that more fuel gas flows to the end of the furnace tube away from the air inlet and is discharged outward from the air outlets through which it flows, thereby improving the uniformity of the fuel gas discharge from various parts of the furnace tube, thereby improving the combustion effect.

[0007] As a further improvement of the above technical solution, the spoiler is connected to the furnace tube by threads. The spoiler and the furnace tube are threadedly connected, the spoiler can be easily disassembled and assembled, and the insertion amount of the spoiler in the furnace tube can be adjusted before use, so as to adjust the spoiler's spoiling effect on the gas to meet the use requirements, thereby improving the flexibility and practicality of use.

[0008] As a further improvement of the above technical solution, a fire stopper is connected to the outer side of the end of the furnace tube relatively far from the air inlet, and a plurality of the air outlet holes are respectively arranged at the positions below the fire stopper on both sides of the furnace tube. The gas in the furnace tube is discharged outward from the plurality of air outlet holes on both sides, and a fire stopper is arranged at the top position of the air inlet end of the furnace tube. The flames at the air outlets on both sides of the furnace tube are shielded by the fire stopper, so that the flames on both sides of the furnace tube can be prevented from converging at the top side of the furnace tube, thereby reducing the temperature of the furnace tube during combustion, avoiding the problem of excessive temperature at the end of the furnace tube affecting the service life, and further improving the combustion effect.

[0009] As a further improvement of the above technical solution, side plates are bent downwards on both sides of the fire baffle, and the two side plates are fixed on the furnace tubes respectively. By fixing the side plates on both sides to the furnace tubes, the connection stability of the fire baffle can be improved, and the flame can burn upward along the guidance of the side plates, reducing the influence of heat radiation upwards, and further improving the combustion effect.

[0010] As a further improvement of the above technical solution, the middle part of the fireproof board extends downwardly at both sides, and the furnace pipe is located below the middle part of the fireproof board. The inclined design on both sides of the fireproof board can form a downward space surrounded by the fireproof board. At this time, the furnace pipe is facing the space, and the fireproof board can better cover the heat of the flame, thereby better reducing the situation where the flame directly jumps out of the fireproof board, further improving the combustion effect.

[0011] As a further improvement of the above technical solution, the utility model further includes a fireproof net, which is against the bottom side of the fireproof board and covers a plurality of the through holes. The fireproof net can evenly conduct heat to the fireproof board, better preventing the flame from directly escaping upward from the through holes, thereby further improving the combustion effect.

[0012] As a further improvement of the above technical solution, the bottom positions of the fireproof board tilted to both sides are respectively provided with card plates, and the two card plates respectively form card slots with the fireproof board, and the left and right sides of the fireproof net are respectively inserted into the two card slots. When the fireproof net is connected to the fireproof board, the middle part of the fireproof net is arched upward to fit the shape of the fireproof board, and the left and right sides are respectively inserted into the two card slots, so that the fireproof net can be fixed. When the fireproof net needs to be removed for maintenance and replacement, it only needs to be removed from the two card slots, which is convenient for disassembly and assembly.

[0013] As a further improvement of the above technical solution, a pressure strip is detachably connected to the fireproof board, and the pressure strip presses the fireproof net to the middle bottom side of the fireproof board. The pressure strip is used to press the middle part of the fireproof net to the middle part of the fireproof board, so that the fireproof net is more closely attached to the fireproof board and the stability of the connection between the two is further improved.

[0014] A heating furnace comprises a furnace body and the above-mentioned furnace head assembly, wherein a plurality of the furnace head assemblies are arranged in the left-right direction, and the front and rear ends of the plurality of furnace tubes and the front and rear ends of the plurality of fireproof panels are respectively connected in the furnace head.

[0015] This technical solution has at least the following beneficial effects: a plurality of burner head assemblies are arranged side by side in the burner head, and since the gas in each burner head assembly is discharged evenly from all parts of the furnace tube, the combustion temperature in the furnace body can be made more uniform, thereby improving the baking effect of the heating furnace on food.

[0016] As a further improvement of the above technical solution, a flame guide plate is connected between two adjacent furnace tubes. After igniting one burner assembly, the flame can spread from the flame guide plate to the adjacent furnace tube, thereby igniting the burner assembly, which can reduce the number of igniters in the heating furnace and is more convenient to use.

[0026] Reference Figure 1 A stove head assembly includes a stove tube 100, a spoiler 200 and a fireproof plate 300, wherein an air inlet 110 is arranged at one end of the stove tube 100, and the end position of the other end of the stove tube 100 is gradually narrowed, flattened and closed to avoid gas leakage at the end, and a plurality of gas outlet holes 120 are arranged on the outer side of the stove tube 100, and the gas outlet holes 120 are respectively arranged on both sides of the stove tube 100, and the gas outlet holes 120 on both sides are arranged along the length direction of the stove tube 100. , and a plurality of air outlet holes 120 are arranged along the circumference of the furnace tube 100 at the top side of the end portion of the furnace tube 100 close to the air inlet 110; a spoiler 200 is connected to the furnace tube 100, and the spoiler 200 is located at the outer side of the end portion of the furnace tube 100 close to the air inlet 110, and the spoiler 200 extends into the interior of the furnace tube 100; a fireproof plate 300 is located above the furnace tube 100, and a plurality of through holes 310 are arranged on the fireproof plate 300.

[0027] As can be seen from the above, one end of the furnace tube 100 is used for air intake, and fuel gas is input into the furnace tube 100 from the air inlet 110. Since the end of the furnace tube 100 close to its air inlet is connected with a spoiler 200, turbulence is caused when the fuel gas passes through the spoiler 200, thereby interfering with the fuel gas from directly discharging from the nearby air outlet 120. In this way, the fuel gas can be reduced from being directly discharged from the air outlet close to the air inlet 110, so that more fuel gas flows to the end of the furnace tube 100 away from the air inlet 110, and is discharged from the air outlet 120 through which it flows, thereby improving the uniformity of the fuel gas discharge from various parts of the furnace tube 100, thereby improving the combustion effect.

[0028] The spoiler 200 is mainly used to block the gas at the end of the furnace tube 100 where the gas is inlet, but it should not block too much gas to avoid excessive accumulation at the inlet end of the furnace tube 100. Therefore, it is necessary to adjust the length of the spoiler 200 inserted into the furnace tube 100 to meet the needs of different furnace tubes 100. In this embodiment, the spoiler 200 is connected to the furnace tube 100 by threads. The spoiler 200 and the furnace tube 100 are threadedly connected, and the spoiler 200 can be easily disassembled and assembled, and the insertion amount of the spoiler 200 in the furnace tube 100 can be adjusted before use, so as to adjust the spoiler 200 The spoiler effect on the gas is adjusted to meet the use needs, thereby improving the flexibility and practicality of use.

[0029] When the furnace tube 100 is in use, the flames generated by the combustion of the gas discharged from both sides are likely to converge at the top side of the furnace tube 100, thereby causing the problem of excessively high temperature in the local area of ​​the furnace tube 100, especially at the end of the furnace tube 100. Therefore, in order to prevent the flames on both sides of the furnace tube 100 from merging upward, Figure 2 As shown, in this embodiment, a fire stopper 400 is connected to the outer side of the end of the furnace tube 100 relatively far from the air inlet 110, and a plurality of the air outlet holes 120 are respectively arranged at the positions below the fire stopper 400 on both sides of the furnace tube 100. The gas in the furnace tube 100 is discharged outwards from the plurality of air outlet holes 120 on both sides, and a fire stopper 400 is arranged at the top position of the air inlet end of the furnace tube 100. The flames at the air outlets on both sides of the furnace tube 100 are shielded by the fire stopper 400, so that the flames on both sides of the furnace tube 100 can be prevented from merging at the top side of the furnace tube 100, thereby reducing the temperature of the furnace tube 100 during combustion, avoiding the problem of excessively high temperature at the end of the furnace tube 100 and affecting the service life, and further improving the combustion effect.

[0030] The fire stopper 400 can be a flat plate structure, which is directly fixed to the top side of the furnace tube 100. At this time, when the flames on both sides heat upward, it is easy to cause the problem that the two sides of the fire stopper affect the upward radiation of heat. Therefore, in this embodiment, the two sides of the fire stopper 400 are respectively bent downward with side panels 410, and the two side panels 410 are respectively fixed to the furnace tube 100. By fixing the side panels 410 on both sides to the furnace tube 100, the connection stability of the fire stopper 400 can be improved, and the flame can burn upward along the guidance of the side panels 410, reducing the influence of heat radiation upward, and further improving the combustion effect. In actual applications, the side panels 410 on both sides can be connected to the furnace tube 100 by snapping, or directly fixed to the furnace tube 100 by welding.

[0031] In some embodiments, the middle of the fireproof board 300 extends downwardly at an angle to both sides, and the furnace tube 100 is located below the middle of the fireproof board 300. In this case, the through holes 310 can be arranged at the angled positions on both sides of the fireproof board 300. The inclined design on both sides of the fireproof board 300 allows the fireproof board 300 to enclose a space facing downwards. At this time, the furnace tube 100 is facing the space, and the fireproof board 300 can better cover the heat of the flame, thereby better reducing the situation where the flame directly jumps out of the fireproof board 300, further improving the combustion effect.

[0032] The utility model further includes a fireproof net 500, which is against the bottom side of the fireproof board 300 and covers the plurality of through holes 310. The fireproof net 500 can evenly conduct heat to the fireproof board 300, better preventing the flame from directly escaping upward from the through holes 310, thereby further improving the combustion effect.

[0033] In order to facilitate the fixing of the fireproof net 500 to the bottom side of the fireproof board 300, in this embodiment, the bottom positions of the fireproof board 300 inclined to both sides are respectively provided with card plates, and the two card plates respectively form card slots with the fireproof board 300, and the left and right sides of the fireproof net 500 are respectively inserted into the two card slots. When the fireproof net 500 is connected to the fireproof board 300, the middle part of the fireproof net 500 is arched upward to fit the shape of the fireproof board 300, and the left and right sides are respectively inserted into the two card slots, so that the fireproof net 500 can be fixed. When the fireproof net 500 needs to be removed for maintenance and replacement, it only needs to be removed from the two card slots, which is convenient for disassembly and assembly.

[0034] In the above embodiment, only the slots formed by the two clamping plates are used to limit the two sides of the fireproof net 500. At this time, the middle part of the fireproof net 500 is arched upward, and the formed bend is less in fit with the bend formed in the middle part of the fireproof board 300. In order to improve the installation stability of the fireproof net 500, in this embodiment, the fireproof board 300 is detachably connected with a pressure strip 510, and the pressure strip 510 presses the fireproof net 500 to the middle bottom side of the fireproof board 300. The pressure strip 510 is used to press the middle part of the fireproof net 500 to the middle part of the fireproof board 300, so that the fireproof net 500 is more closely attached to the fireproof board 300, and the stability of the connection between the two is further improved. In actual application, downwardly protruding clamping holes can be formed at the front and rear positions in the middle of the fireproof board 300, and the two ends of the two pressure strips 510 are respectively connected to the two clamping hole positions, so that the installation of the pressure strip 510 can be achieved.

[0035] In practical applications, in order to improve the structural strength of the fireproof board 300, the inclined ends of the two sides of the fireproof board 300 can be bent downward to form two flanges. The two flanges are inclined from top to bottom toward each other, which can better gather the flames emitted by the tube furnace and make the fireproof board 300 not easy to bend and deform.

[0036] like Figure 3 As shown, a heating furnace includes a furnace body 600 and the above-mentioned furnace head assembly, wherein the furnace head assembly is arranged in plurality along the left-right direction, and the front and rear ends of the plurality of furnace tubes 100 and the front and rear ends of the plurality of fireproof panels 300 are respectively connected in the furnace head.

[0037] In this embodiment, a plurality of burner head assemblies are arranged side by side in the burner head. Since the gas in each burner head assembly is discharged evenly from all parts of the furnace tube 100, the combustion temperature in the furnace body 600 can be made more uniform, thereby improving the baking effect of the heating furnace on food.

[0038] For the installation of the furnace tube 100 in the furnace body 600, the flat end of the furnace tube 100 can be directly fixed to the front side of the furnace body 600, and an installation hole for installing and positioning the air inlet end of the furnace tube 100 is set on the rear side of the furnace body 600. For the installation of the fireproof board 300 in the furnace body 600, a step extending in the left and right directions can be set on the rear side of the furnace body 600, and the rear side of the fireproof board 300 is placed on the step. A positioning column is provided on the front side of the furnace body 600, and the middle front side of the fireproof board 300 is placed on the positioning column, so that the installation and positioning of the fireproof board 300 can be achieved.

[0039] In some embodiments, a flame guide plate 610 is connected between two adjacent furnace tubes 100. After igniting one burner assembly, the flame can spread from the flame guide plate 610 to the adjacent furnace tube 100, thereby igniting the burner assembly, which can reduce the number of igniters in the heating furnace and is more convenient to use.

[0040] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments.
