Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-3 The present invention provides an embodiment of a heating furnace shell structure with a high-efficiency heat insulation jacket, comprising a radiation chamber 1, a sealed door at one end of the radiation chamber 1 for easy opening of the heating furnace, a convection chamber 2 at the top of the radiation chamber 1, a filter screen at the bottom of the convection chamber 2 near the heat exchange tube 44 for filtering the exhaust gas and preventing the discharge of slag and pollution of the air, an exhaust pipe 3 at the top of the convection chamber 2, a waste heat insulation component 4 at the inside of the radiation chamber 1, a vacuum insulation component 5 between the radiation chamber 1 and the waste heat insulation component 4, and a burner 6 at the inside of the waste heat insulation component 4.
[0023] The waste heat insulation component 4 includes an insulating liner 41, a flow chamber 42, a fan 43, a heat exchange pipe 44, a guide pipe 45, and an exhaust pipe 46. The insulating liner 41 is located inside the radiation chamber 1 and is made of aluminosilicate ceramic fiberboard. A metal reflective layer is provided on the outer side of the insulating liner 41 to improve its fire resistance and heat insulation performance. The metal reflective layer reduces radiative heat transfer through multiple reflections, thus improving the insulation effect of the device. The interior of the insulating liner 41 is open... The system includes a flow chamber 42, a fan 43 on one side of the convection chamber 2, a heat exchange tube 44 connected to the fan 43 on the inner side of the convection chamber 2, a guide pipe 45 connected to the flow chamber 42 on one side of the heat exchange tube 44, an exhaust pipe 46 connected to the flow chamber 42 at the bottom of the radiation chamber 1, and two sets of connecting pipes connected to the exhaust pipe 46 at the bottom of the flow chamber 42, which can connect the exhaust pipe 46 and the flow chamber 42 to guide the exhaust.
[0024] The vacuum insulation assembly 5 includes a vacuum jacket 51, a vacuum tube 52, a sleeve 53, a guide groove 54, a guide rod 55, a piston 56, a spring 57, a contact block 58, a contact piece 59, and an indicator light 510. The vacuum jacket 51 is located between the radiation chamber 1 and the insulation liner 41. A vacuum tube 52 connected to the vacuum jacket 51 is provided on one side of the radiation chamber 1, and a sleeve 53 connected to the vacuum jacket 51 is provided on the other side of the radiation chamber 1. One side of the inner side of the sleeve 53 is... There is a guide groove 54, and a guide rod 55 is sleeved on the inner side of the guide groove 54. A piston 56 adapted to the sleeve 53 is provided on one side of the guide rod 55. A spring 57 is sleeved on the outer side of the guide rod 55. A contact block 58 is provided on one side of the inner side of the guide groove 54. A contact piece 59 that cooperates with the contact block 58 is provided on the side of the guide rod 55 away from the piston 56. An indicator light 510 is provided on one side of the radiation chamber 1 near the bottom of the sleeve 53. Air convection can be eliminated through the heat insulation lining 41 to improve the heat insulation performance.
[0025] Working principle: When used in the heating furnace, the heat insulation performance of the device can be enhanced by the heat insulation lining 41. The airflow can be drawn into the heat exchange tube 44 by the fan 43. Then the airflow exchanges heat with the exhaust, reducing the exhaust temperature and effectively utilizing the exhaust waste heat. The hot air after heat exchange can enter the flow chamber 42 through the guide pipe 45. When the hot air passes through the flow chamber 42, it can form a heat insulation layer on the outside of the combustion chamber, thereby preventing heat loss and further improving the heat insulation performance of the device.
[0026] The vacuum interlayer 51 can eliminate air convection and reflective radiant heat to achieve efficient heat insulation. Due to the vacuum negative pressure state inside the vacuum interlayer 51, when the vacuum degree is normal, the negative pressure suction can drive the guide rod 55 to move to one side against the elastic force of the spring 57. When the vacuum degree inside the vacuum interlayer 51 decreases, its negative pressure suction also decreases at the same time. At this time, the negative pressure suction cannot overcome the elastic force of the spring 57, so that the contact piece 59 can move closer to the contact block 58. When the contact piece 59 contacts the contact block 58, the automatic indicator light 510 can remind the staff, and the vacuum interlayer 51 can be evacuated again to ensure the vacuum degree inside the vacuum interlayer 51.
