Technical Field
[0001] The utility model relates to the technical field of glass furnaces, in particular to a heat preservation structure for a glass furnace. Background Technique

[0003] Ordinary glass furnaces are insulated inside the furnace through a multi-layer insulation structure. However, this method can only slow down the rate of temperature drop, and ordinary furnaces directly discharge the waste gas to the outside world. Along with the waste gas, there is also a lot of heat discharged, resulting in heat loss. Content of the Utility Model
[0004] The purpose of the utility model is to provide a heat preservation structure for a glass furnace to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a heat preservation structure for a glass furnace, including a furnace body. A melting pool is arranged inside the furnace body. The furnace body is made of refractory bricks. A plurality of through exhaust holes are opened above the left and right sides of the inner surface of the furnace body. An asbestos insulation board I is fixedly arranged on the outer surface of the furnace body. An aluminum shell is arranged on the outer surface of the asbestos insulation board I. A stainless steel shell is fixedly connected to the outer surface of the aluminum shell. A refractory hollow brick is fixedly connected below the furnace body. An asbestos insulation board II is arranged below the refractory hollow brick. A closing door is rotatably connected to the left side of the front surface of the stainless steel shell.
[0006] Preferably, a through exhaust pipe hole I is opened on the left side surface of the aluminum shell, and a plurality of through exhaust pipe holes II are opened on the right side of the aluminum shell. A smoke exhaust pipe I is movably connected inside the exhaust pipe hole I and the exhaust pipe hole II. The smoke exhaust pipe I passes through the asbestos insulation board I and is fixedly connected to the furnace body through the exhaust hole. A communicating pipe is connected through the middle of the left side of the smoke exhaust pipe I. A smoke exhaust pipe II is connected through the middle of the communicating pipe. The smoke exhaust pipe II passes through the stainless steel shell.
[0007] Preferably, a water inlet pipe is connected through the upper part of the rear surface of the aluminum shell, and a drain pipe is connected through the lower part of the rear surface of the aluminum shell.
[0008] Preferably, a plurality of through holes are opened inside the refractory hollow brick, and the through holes are movably connected to the smoke exhaust pipe I.
[0009] Preferably, a heating pipe is fixedly connected to the upper surface of the aluminum shell, and the heating pipe is located between the aluminum shell and the stainless steel shell.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] 1. Through the mutual cooperation of the first exhaust pipe, the connecting pipe and the second exhaust pipe provided by the utility model, the generated waste gas will enter the interior of the first exhaust pipe through the exhaust holes. The waste gas will enter the interior of the connecting pipe along the arrangement of the first exhaust pipe, then enter the interior of the second exhaust pipe through the connecting pipe, and be discharged to the outside through the second exhaust pipe. Since the waste gas carries heat, in this process, the first exhaust pipe will absorb part of the heat in the waste gas, causing the temperature of the first exhaust pipe to rise. The heat on the surface of the first exhaust pipe will also be dissipated into the interior of the refractory hollow bricks, and the heat will be better transferred to each cell of the refractory hollow bricks through the through holes. And the heat loss of each cell of the refractory hollow bricks can be prevented from being too fast under the action of the second asbestos insulation board, thereby increasing the temperature outside the kiln body. This not only makes full use of the heat in the waste gas but also improves the heat preservation effect of the kiln body.
[0012] 2. Through the mutual cooperation of the heating pipe, the aluminum shell, the water inlet pipe and the drain pipe provided by the utility model, water can be injected into the interior of the aluminum shell through the water inlet pipe to heat the upper surface of the aluminum shell through the heating pipe. Because of the heat conduction characteristics of aluminum, the water inside can be heated, achieving a better heat preservation effect for the kiln body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.
[0020] Please refer to Figure 1 , the present invention provides a technical solution: a glass kiln furnace thermal insulation structure, including a kiln body 2, a melting pool 1 is arranged inside the kiln body 2, the kiln body 2 is made of refractory bricks, and a plurality of through exhaust holes 6 are opened above the left and right sides of the inner surface of the kiln body 2. An asbestos thermal insulation board 1 is fixedly arranged on the outer surface of the kiln body 2. An aluminum shell 4 is arranged on the outer surface of the asbestos thermal insulation board 1. A stainless steel shell 5 is fixedly connected to the outer surface of the aluminum shell 4. A refractory hollow brick 7 is fixedly connected to the lower surface of the kiln body 2. An asbestos thermal insulation board 2 is arranged below the refractory hollow brick 7. A closing door 9 is rotatably connected to the left side of the front surface of the stainless steel shell 5.
[0021] The stainless steel shell 5 can protect the internal heating pipe 801 and make the thermal insulation structure more firm. The refractory hollow brick 7 can make the lower part of the entire kiln body 2 in a hollow state, increasing the thermal insulation effect.
[0022] Please refer to Figure 2 、 Figure 3 , a through exhaust pipe hole 1 is opened on the left surface of the aluminum shell 4, and a plurality of through exhaust pipe holes 2 are opened on the right side of the aluminum shell 4. A smoke exhaust pipe 1 is movably connected inside the exhaust pipe hole 1 and the exhaust pipe hole 2. The smoke exhaust pipe 1 passes through the asbestos thermal insulation board 1 and is fixedly connected to the kiln body 2 through the exhaust hole 6. A communication pipe 2 is connected to the middle of the left side of the smoke exhaust pipe 1. A smoke exhaust pipe 3 is connected to the communication pipe 2 in a through manner. The smoke exhaust pipe 3 passes through the stainless steel shell 5.
[0023] A water inlet pipe 6 is connected to the upper part of the rear surface of the aluminum shell 4 in a through manner, and a drain pipe 7 is connected to the lower part of the rear surface of the aluminum shell 4 in a through manner.
[0024] Water can be injected into the aluminum shell 4 through the water inlet pipe, and the water in the aluminum shell 4 is heated to achieve a better thermal insulation effect on the kiln body 2. The water in the aluminum shell 4 can be discharged through the drain pipe.
[0025] When melting glass raw materials, the generated waste gas will enter the interior of the first exhaust pipe 601 through the exhaust holes 6. The waste gas will enter the interior of the connecting pipe 602 along the arrangement of the first exhaust pipe 601, then enter the interior of the second exhaust pipe 603 through the connecting pipe 602, and be discharged to the outside through the second exhaust pipe 603. Since the waste gas carries heat, during this process, the first exhaust pipe 601 will absorb part of the heat in the waste gas, causing the temperature of the first exhaust pipe 601 to rise, and then increasing the temperature outside the kiln body 2. This not only utilizes the heat in the waste gas but also has a better heat preservation effect on the kiln body 2.
[0026] Please refer to Figure 4 , a plurality of through holes 701 are provided inside the refractory hollow brick 7, and the through holes 701 are movably connected to the first exhaust pipe 601.
[0027] Since the surface of the first exhaust pipe 601 carries heat, the heat on the surface of the first exhaust pipe 601 will also be dissipated into the interior of the refractory hollow brick 7, and the heat will be better transferred to each cell interior of the refractory hollow brick 7 through the through holes 701, so that the bottom of the kiln body 2 can also be heated and insulated.
[0028] Please refer to Figure 5 , a heating pipe 801 is fixedly connected to the upper surface of the aluminum shell 4, and the heating pipe 801 is located between the aluminum shell 4 and the stainless steel shell 5.
[0029] The aluminum shell 4 can be heated through the heating pipe.
[0030] Working principle: When melting glass raw materials, the generated waste gas will enter the interior of the first exhaust pipe 601 through the exhaust holes 6. The waste gas will enter the interior of the connecting pipe 602 along the arrangement of the first exhaust pipe 601, then enter the interior of the second exhaust pipe 603 through the connecting pipe 602, and be discharged to the outside through the second exhaust pipe 603. Since the waste gas carries heat, during this process, the first exhaust pipe 601 will absorb part of the heat in the waste gas, causing the temperature of the first exhaust pipe 601 to rise. The heat on the surface of the first exhaust pipe 601 will also be dissipated into the interior of the refractory hollow brick 7, and the heat will be better transferred to each cell interior of the refractory hollow brick 7 through the through holes 701. And the heat preservation board two 8 can prevent the heat in each cell interior of the refractory hollow brick 7 from dissipating quickly, thereby increasing the temperature outside the kiln body 2. This not only utilizes the heat in the waste gas but also improves the heat preservation effect on the kiln body 2. Water can be injected into the aluminum shell 4 through the water inlet pipe to heat the upper surface of the aluminum shell 4 through the heating pipe 801. Because of the heat conduction characteristics of aluminum, the water inside can be heated, achieving a better heat preservation effect on the kiln body 2. The water inside the aluminum shell 4 can be discharged through the drain pipe.
[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
