DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.
[0024] Please refer to Figures 1-4 The utility model provides a technical scheme: a novel industrial kiln heat pipeline energy -conserving heat preservation structure, including heat pipeline 1, still include: heat reflection assembly 2, heat reflection assembly 2 sets up at heat pipeline 1 outside, heat reflection assembly 2 is used for reducing the loss of heat in heat pipeline 1, heat preservation assembly 3, heat preservation assembly 3 sets up at heat reflection assembly 2 outside, heat preservation assembly 3 is used for preventing the heat loss in heat pipeline 1, and protection assembly 4, protection assembly 4 sets up at heat preservation assembly 3 outside, and protection assembly 4 is used for protecting heat pipeline 1,
[0025] Due to heat reflection assembly 2 compound in the outer wall surface of heat pipeline 1, so that heat reflection assembly 2 can reduce the heat loss in heat pipeline 1, in turn can make heat be more effectively absorbed by the material or product in the furnace, due to heat reflection assembly 2 outer wall compound has heat preservation assembly 3, so that heat preservation assembly 3 can reduce the heat loss of heat pipeline 1 in heat transmission process, in turn can reduce the heat energy from the pipeline to the surrounding environment, so as to can improve the heat energy utilization efficiency, due to heat preservation assembly 3 outside fixedly connected with protection assembly 4, so as to can isolate the direct contact of pipeline and corrosive environment, in turn can reduce the wear and tear of heat pipeline 1, protect the inner wall of pipeline, so as to can prolong the service life of pipeline.
[0026] Please refer to Figure 1 , Figure 2 , heat reflection assembly 2 includes epoxy resin coating layer 21, and epoxy resin coating layer 21 is applied to heat pipeline 1 outside, and epoxy resin coating layer 21 outside compound has nano alumina layer 22, and nano alumina layer 22 outside compound has aluminized film layer 23;
[0027] By the epoxy paint layer 21 in the heat reflecting assembly 2, since the epoxy paint layer 21 is coated on the outer wall of the heat pipe 1, a dense protective film can be formed, which can effectively isolate the air, moisture and other corrosive media from contacting the metal surface of the pipe, so as to prevent the pipe from corrosion. Since the epoxy paint layer 21 is compounded with the nano-alumina layer 22 on the outside, and the nano-alumina layer 22 has high reflectivity, the nano-alumina layer 22 can reflect part of the heat radiation, which can reduce the loss of heat energy. Since the nano-alumina layer 22 is compounded with the aluminized film layer 23 on the outside, the aluminized film layer 23 can reflect the heat energy reflected by the nano-alumina layer 22 again, which can improve the reflection effect, so as to improve the utilization efficiency of heat energy.
[0028] Referring to Figure 1 , Figure 3 , the heat preservation assembly 3 comprises a ceramic fiber blanket layer 31, the ceramic fiber blanket layer 31 is compounded on the outside of the aluminized film layer 23, the ceramic fiber blanket layer 31 is compounded with a silicate heat preservation coating layer 32 on the outside, the silicate heat preservation coating layer 32 is compounded with a polyurethane foam layer 33 on the outside, the ceramic fiber blanket layer 31 is compounded with a steel mesh 34 on the outside, and the steel mesh 34 is coated with anticorrosive paint on the outside.
[0029] By the ceramic fiber blanket layer 31 in the heat preservation assembly 3, since the ceramic fiber blanket layer 31 is compounded on the outside of the steel mesh 24, and the ceramic fiber blanket layer has low thermal conductivity, the heat loss can be effectively reduced, which can keep the temperature inside the pipe stable, so as to improve the utilization efficiency of heat energy and reduce energy consumption. Since the ceramic fiber blanket layer 31 is compounded with the silicate heat preservation coating layer 32 on the outside, and has low thermal conductivity, the heat preservation performance of the pipe can be further improved, the heat loss can be reduced, which can protect the ceramic fiber blanket layer 31 from the influence of the external environment, so as to prolong the service life of the heat preservation structure. Since the silicate heat preservation coating layer 32 is compounded with the polyurethane foam layer 33 on the outside, and has very low thermal conductivity, the heat loss of the heat pipe can be effectively reduced, which can keep the temperature of the medium inside the pipe stable, so as to improve the heat efficiency and save energy. Since the ceramic fiber blanket layer 31 is fixedly connected with the steel mesh 34 on the outside, the steel mesh 34 can fix the ceramic fiber blanket layer 31, which can prevent it from displacement or falling off during use, so as to make it more stable in high temperature environment and not easy to be damaged. Since the steel mesh 34 is coated with anticorrosive paint on the outside, the corrosion speed of the steel mesh 34 can be slowed down, which can effectively prolong the service life of the steel mesh 34, so as to improve the stability of the ceramic fiber blanket.
[0030] Referring to Figure 1 , Figure 4The protection assembly 4 comprises a first protective cover 41 provided outside the polyurethane foam layer 33, a second protective cover 42 provided at the bottom surface of the first protective cover 41, a stop ring 43 provided at two ends of the first protective cover 41 and the second protective cover 42 respectively, an internally threaded hole 44 formed at one side of the first protective cover 41 and the second protective cover 42, a plurality of internally threaded holes 44 arranged in a circumferential array, a fixing bolt 45 provided at one side of the two stop rings 43, a plurality of fixing bolts 45 arranged in a circumferential array, one end of the fixing bolt 45 connected with the internally threaded hole 44, an insertion slot 46 formed at both sides of the bottom surface of the first protective cover 41, and an insertion block 47 provided at both sides of the top surface of the second protective cover 42. The inner diameter of the stop ring 43 is the same as the outer diameter of the heat pipe 1, and the two are matched.
[0031] The first protective cover 41 of the protection assembly 4 can be fixedly connected outside the polyurethane foam layer 33 and provide a mounting base for the second protective cover 42. The first protective cover 41 and the second protective cover 42 are fixedly connected with the stop rings 43 at two ends, and a plurality of internally threaded holes 44 are formed at one side of the first protective cover 41 and the second protective cover 42. The two stop rings 43 are fixedly connected with a plurality of fixing bolts 45 at one side, and one end of the fixing bolt 45 is connected with the internally threaded hole 44. Thus, the stop ring 43 can fix the first protective cover 41 and the second protective cover 42 through the fixing bolt 45, and the first protective cover 41 and the first protective cover 41 can protect the heat pipe 1. This can prevent damage to the heat pipe 1 and improve the safety of the heat pipe 1.

[0032] During operation, the heat reflection assembly 2 is combined with the outer wall surface of the heat pipe 1, which can reduce the heat loss of the heat pipe 1 and make the heat more effectively absorbed by the materials or products in the furnace. The outer wall of the heat reflection assembly 2 is combined with the heat preservation assembly 3, which can reduce the heat loss of the heat pipe 1 during heat transmission and reduce the heat loss from the pipe to the surrounding environment, thereby improving the utilization efficiency of heat energy. The heat preservation assembly 3 is fixedly connected with the protection assembly 4 outside, which can isolate the pipe from direct contact with the corrosive environment and reduce the wear of the heat pipe 1, thereby protecting the inner wall of the pipe and prolonging the service life of the pipe.
[0033] The epoxy paint layer 21 in the heat-reflecting assembly 2 can form a dense protective film due to the fact that the epoxy paint layer 21 is coated on the outer wall of the heat pipe 1, thereby effectively preventing air, moisture and other corrosive media from contacting the metal surface of the pipe, so as to prevent corrosion of the pipe. The nano-alumina layer 22 is coated on the outer side of the epoxy paint layer 21, and has high reflectivity, so that the nano-alumina layer 22 can reflect part of the heat radiation, thereby reducing the loss of heat energy. The aluminized film layer 23 is coated on the outer side of the nano-alumina layer 22, so that the aluminized film layer 23 can reflect the heat energy reflected by the nano-alumina layer 22 again, thereby improving the reflection effect, so as to improve the utilization efficiency of heat energy.
[0034] The ceramic fiber blanket layer 31 in the heat-insulating assembly 3 can effectively reduce the loss of heat due to the fact that the ceramic fiber blanket layer 31 is combined on the outer side of the steel wire mesh 24, and has a low thermal conductivity, thereby maintaining the stability of the internal temperature of the pipe, so as to improve the utilization efficiency of heat energy and reduce energy consumption. The silicate heat-insulating coating layer 32 is combined on the outer side of the ceramic fiber blanket layer 31, and has a low thermal conductivity, thereby further improving the heat-insulating performance of the pipe, reducing heat loss, and protecting the ceramic fiber blanket layer 31 from the external environment, so as to prolong the service life of the heat-insulating structure. The polyurethane foam layer 33 is combined on the outer side of the silicate heat-insulating coating layer 32, and has a very low thermal conductivity, thereby effectively reducing the heat loss of the heat pipe, maintaining the stability of the temperature of the medium in the pipe, so as to improve the heat efficiency and save energy. The steel wire mesh 34 is fixedly connected to the outer side of the ceramic fiber blanket layer 31, so that the steel wire mesh 34 can fix the ceramic fiber blanket layer 31, thereby preventing displacement or falling of the ceramic fiber blanket layer 31 during use, so as to make it more stable and less likely to be damaged in a high-temperature environment. The steel wire mesh 34 is coated with anticorrosive paint on the outer side, so as to slow down the corrosion of the steel wire mesh 34, thereby effectively prolonging the service life of the steel wire mesh 34, so as to improve the stability of the ceramic fiber blanket layer 31.
[0035] The first protective cover 41 in the protection assembly 4 can be fixedly connected outside the polyurethane foam layer 33 and provide a mounting base for the second protective cover 42. Since the first protective cover 41 and the second protective cover 42 are fixedly connected with the stop rings 43 at two ends, respectively, and a plurality of internally-threaded holes 44 are formed on one side of the first protective cover 41 and the second protective cover 42, and a plurality of fixing bolts 45 are fixedly connected on one side of the two stop rings 43, and one end of the fixing bolts 45 is connected with the internally-threaded holes 44, the stop rings 43 can fix the first protective cover 41 and the second protective cover 42 through the fixing bolts 45, so as to protect the heat pipe 1 by the first protective cover 41 and the first protective cover 41, which can prevent damage to the heat pipe 1 and improve the safety of the heat pipe 1. Since the bottom surface of the first protective cover 41 is provided with the insertion grooves 46 on both sides, and the top surface of the second protective cover 42 is fixedly connected with the insertion blocks 47 on both sides, the insertion blocks 47 can be inserted into the inner cavities of the insertion grooves 46, which can improve the sealing performance of the first protective cover 41 and the second protective cover 42, prevent air from corroding the outer wall of the heat pipe 1, and prolong the service life of the heat pipe 1.
