The function of the furnace chamber is to ensure that the fuel burns out as much as possible and to cool the flue gas temperature at the furnace chamber outlet to a temperature that allows the convective heating surface to operate safely. The existing furnace chambers are mainly formed by die pressing high-temperature resistant materials (such as alumina ceramics, silicon carbide, etc.). During actual use, due to the lack of an external support and protection mechanism, the furnace chamber is prone to cracking and other problems due to factors such as thermal expansion and contraction, and collision during actual use, thus affecting the normal use of the device.

DETAILED DESCRIPTION OF THE INVENTION
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-7 The present invention provides a technical solution: a target furnace hearth structure for preventing cracking during molding, including a hearth body 1 and an outer protection frame 2. The outer protection frame 2 is installed on the outer side of the hearth body 1, and a polycrystalline fiber blanket (which can withstand a high temperature of 1600°) is covered on the outer side of the hearth body 1. The outer protection frame 2 includes a protection plate 201 in contact with the outer wall of the hearth body 1. Through holes 202 are evenly formed in the protection plate 201. Vertical rib plates 203 are fixedly arranged at equal intervals on the protection plate 201. The vertical rib plates 203 and the horizontal rib plates 204 are nestedly connected, and the horizontal rib plates 204 and the protection plate 201 are fixedly connected. An upper frame 205 in contact with the hearth body 1 is fixedly arranged on the upper side of the protection plate 201. A support 206 is fixed on the upper frame 205, and a top plate 207 in contact with the upper end face of the hearth body 1 is fixed on the support 206. A bottom plate 3 in contact with the lower end face of the hearth body 1 is fixedly arranged on the lower end face of the protection plate 201, and a support frame 4 is fixed on the lower end face of the bottom plate 3.
[0019] When using this target furnace hearth structure for preventing cracking during molding, as Figures 1-7 shown, first, the hearth body 1 and the outer protection frame 2 are sleeved and assembled. When the hearth body 1 and the outer protection frame 2 are assembled, through the function of the through holes 202, the air between the hearth body 1 and the outer protection frame 2 can be effectively discharged, thereby improving the convenience of assembling the hearth body 1 and the outer protection frame 2. After the assembly is completed, through the fixation of the bottom plate 3 and the protection plate 201, the limiting function of the lower side of the outer protection frame 2 and the hearth body 1 can be realized, ensuring that the outer protection frame 2 and the hearth body 1 form an integral structure. At this time, the protection plate 201 can support and protect the side of the hearth body 1, and the top plate 207 can limit and protect the upper end face of the hearth body 1, thereby effectively preventing the hearth body 1 from cracking due to large deformation caused by thermal expansion and contraction during the later use process, and further extending the service life of the hearth body 1; A smoke exhaust pipe 5 is connected to the furnace body 1, and the smoke exhaust pipe 5 communicates with the diversion pipe 6, and the diversion pipe 6 is installed on the top plate 207. A gas fuel pipe 8 is connected to the furnace body 1, and the gas fuel pipe 8 is connected to the burner inside the furnace body 1. An air pipe 601 communicating with the furnace body 1 is installed in the diversion pipe 6, and the upper end of the air pipe 601 is connected to the fixed box 7. An exhaust pipe 602 is installed on the left side of the diversion pipe 6. An air inlet 701 is installed at the upper end of the fixed box 7, and the air inlet 701 is connected to an air pump through a conduit. A pressure stabilizing port 702 is provided on the side of the fixed box 7, and an adjusting mechanism 9 is connected between the fixed box 7 and the gas fuel pipe 8, and a pressure stabilizing mechanism 10 is installed in the fixed box 7. The adjusting mechanism 9 includes a connecting pipe 901 connected to the fixed box 7 and the gas fuel pipe 8. A partition 902 is fixed in the connecting pipe 901, and the partition 902 is slidably connected to the piston 903. One end of the spring 904 of the piston 903 is fixed to each other, and the other end of the spring 904 is fixed to the partition 902. The piston 903 is rotatably connected to one end of the connecting rod 905, and the other end of the connecting rod 905 is rotatably connected to the first baffle 906, and the first baffle 906 is in sliding contact with the upper end opening of the air pipe 601 in the fixed box 7. A fixing plate 907 is fixed on the first baffle 906, and the fixing plate 907 is slidably connected to the guide rod 908, and the guide rod 908 is fixed in the fixed box 7. At the same time, a first rack 909 is fixed on the fixing plate 907; During the use of the device, as Figures 1-7 shown, gas can be supplied to the burner installed in the furnace body 1 through the gas fuel pipe 8, thereby providing a basic guarantee for heating the inside of the furnace body 1. And during the gas supply process, at this time, due to the air pressure in the gas fuel pipe 8, the piston 903 is forced to slide in the connecting pipe 901. With the sliding guiding effect between the partition 902 and the piston 903, the stability of the movement of the piston 903 can be ensured. When the piston 903 moves, with the transmission effect of the connecting rod 905, the first baffle 906 is forced to move. With the sliding guiding effect between the fixing plate 907 and the guide rod 908, the stability of the movement of the first baffle 906 can be ensured, thereby opening the upper end opening of the air pipe 601. And since the size of the upper end opening of the air pipe 601 is affected by the air pressure in the gas fuel pipe 8, it can be ensured that when the gas pressure in the gas fuel pipe 8 increases, the upper end opening of the air pipe 601 increases, and vice versa. By controlling the size of the upper end opening of the air pipe 601, the flow rate of the outside air entering the furnace body 1 through the air inlet 701 and the air pipe 601 under the action of the air pump can be controlled, so that the air flow rate and the gas flow rate can be ensured to be proportional, effectively avoiding problems such as incomplete combustion or deflagration of the gas, thereby effectively ensuring the use safety of the device; The voltage stabilizing mechanism 10 includes a second baffle 1001 in contact with the fixed box 7. The second baffle 1001 is symmetrically fixed with slide bars 1002 up and down, and the slide bars 1002 are slidably connected to the fixed box 7. A second rack 1003 is fixed on the second baffle 1001, and the second rack 1003 is meshed with a gear 1004. The gear 1004 is connected by bearings in the fixed box 7, and the gear 1004 is meshed with a first rack 909. When adjusting the upper opening of the air pipe 601, as Figures 1-7 shown, by the movement of the fixed plate 907, the first rack 909 is synchronously driven to move. With the transmission among the first rack 909, the gear 1004 and the second rack 1003, the second baffle 1001 is forced to move, so as to adjust the opening size of the voltage stabilizing port 702 by the second baffle 1001. That is, when the upper opening of the air pipe 601 increases, the opening of the voltage stabilizing port 702 decreases; when the upper opening of the air pipe 601 decreases, the opening of the voltage stabilizing port 702 increases. Thus, when the air pump stably conveys air flow into the fixed box 7, through the action of the air pipe 601 and the voltage stabilizing port 702, the gas shunting effect can be realized, and then the air pressure in the fixed box 7 can be always kept stable, avoiding damage to the fixed box 7 and effectively prolonging the service life of the fixed box 7. During the use of the device, after the gas burns in the furnace body 1, the high-temperature waste gas is discharged through the smoke exhaust pipe 5, the diversion pipe 6 and the exhaust pipe 602. During the flow of the high-temperature waste gas in the diversion pipe 6, the air entering the furnace body 1 in the air pipe 601 can be dried and heated, so that the heat of the waste gas can be utilized. And by preheating the entering air, the fuel consumption can be reduced, thus reducing the energy consumption during the combustion process. This is the working principle of the target furnace furnace structure with die pressing anti-cracking.
