[0021] In order to make the technical purpose, technical scheme and beneficial effect of the utility model more clearly, the technical scheme of the utility model is further explained as follows by combining with the drawing and specific embodiment.
[0022] Embodiment 1
[0023] The utility model provides a kind of baking device, including flue gas passage, conveyor 9 and tunnel kiln 10, flue gas passage is equipped with inlet 1 and outlet 2, each section of flue gas passage is defined as high-temperature section, conventional section and low-temperature section in order from the direction of inlet 1 to outlet 2 respectively.
[0024] High-temperature section's upper wall is laid with heat barrier layer 3, its effect is to slow down heat conduction, when high-temperature flue gas enters high-temperature section, heat barrier layer 3 can effectively prevent heat to be transferred to baking space too fast, so that the heat carried by high-temperature flue gas is as much as possible to subsequent area needing heat transmission, not only improve the utilization efficiency of heat, also can make the temperature of high-temperature section tend to conventional section temperature, to maintain relatively uniform reasonable temperature distribution in the whole baking space.
[0025] The upper wall of low-temperature section is provided with heat conduction structure, and the heat conduction structure is arranged as a plurality of heat dissipation pipes 5 arranged at intervals along the length direction of the low-temperature section.
[0026] The opening of the heat dissipation pipe 5 is covered with a mesh cover 6 to prevent foreign matter from entering the heat dissipation pipe 5 and to avoid blocking the heat dissipation pipe 5 and affecting the heat conduction efficiency.
[0027] The conventional section plays a transitional role in the baking space, and it connects the high-temperature section and the low-temperature section.
[0028] The heat barrier layer 3 is composed of a material with good heat insulation performance, such as fine sand or small stones.
[0029] The side wall of the flue gas passage is provided with a dust removal window 7.
[0030] The conveyor 9 crosses the baking space, and the main function of the conveyor 9 is to convey the materials or other objects that need to be heated. When the materials move above the baking space through the conveyor 9, the heat in the baking space can be transferred to the materials through heat conduction, heat radiation, etc., to achieve the heating of the materials. The conveyor 9 and the baking space are both arranged in the tunnel kiln 10, and the tunnel kiln 10 provides a relatively closed space for the entire device, which is conducive to maintaining a stable temperature environment and improving efficiency. The inner wall of the tunnel kiln 10 is usually made of high-temperature-resistant material and can withstand high-temperature thermal shock.
[0031] In this embodiment, the smoke inlet 1 is arranged in the middle of the flue gas passage, and the smoke outlet 2 is arranged at both ends of the flue gas passage, that is, the flue gas passage from the middle to both ends is sequentially connected with the high-temperature section, the stable section and the low-temperature section.
[0032] The working principle of the device is as follows:
[0033] When the high-temperature flue gas generated by the furnace enters the high-temperature section of the flue gas passage through the smoke inlet 1, the heat-blocking layer 3 slows down the heat conduction, so that as much heat as possible in the high-temperature flue gas is transferred to the subsequent area. As the flue gas gradually flows to the conventional section and the low-temperature section, the temperature gradually decreases, and in the low-temperature section, the heat dissipation pipe 5 accelerates the heat conduction to transfer the heat in the low-temperature flue gas. The conveyor 9 conveys the materials that need to be heated through the tunnel kiln 10, and the heat in the baking space heats the materials through heat conduction, etc.
[0034] Embodiment 2
[0035] The difference between embodiment 2 and embodiment 1 is the specific structure of the flue gas passage and the length structure of the adjacent heat dissipation pipes 5. The flue gas passage of embodiment 1 is a rectangular structure and extends axially to both ends, and the length of the adjacent heat dissipation pipes 5 gradually increases from the high-temperature section to the low-temperature section. The difference between embodiment 2 is as follows:
[0036] The flue gas passage is in a serpentine structure, and the outer side between the adjacent two rows of the flue gas passage is sleeved with a heat shield for sealing the space between them, that is, the adjacent two rows of the flue gas passage and the heat shield arranged correspondingly cooperate to form the baking space. The heat shield is provided with a box door 8 for controlling the communication between the inside and outside of the baking space. The box door 8 is arranged to facilitate the taking and placing of objects in the baking space, and has good sealing and heat insulation performance to ensure that the temperature in the baking space is not affected by the outside environment.
[0037] The lengths of the heat dissipation pipes 5 in the same row of the flue gas passage are equal, and the lengths of the heat dissipation pipes 5 arranged on the adjacent rows of the flue gas passage are arranged such that the length of the heat dissipation pipe 5 arranged on the flue gas passage away from the high-temperature section is greater than the length of the heat dissipation pipe 5 arranged on the flue gas passage close to the high-temperature section. The entire device is provided with a heat preservation layer on the surface.
[0038] The working principle of the device is as follows:
[0039] When the high-temperature flue gas generated by the furnace enters the high-temperature section of the flue gas passage from the flue gas inlet 1, the heat-blocking layer 3 slows down the heat conduction, so that as much heat as possible in the high-temperature flue gas is transmitted to the subsequent area. As the flue gas gradually flows to the normal section and the low-temperature section, the temperature gradually decreases, and in the low-temperature section, the heat dissipation pipe 5 transmits the heat in the low-temperature flue gas to the baking space by accelerating the heat conduction. The material is heated while placed in the baking space.
[0040] Finally, it should be noted that the above examples are only used to illustrate and not limit the technical solutions of the present application. Any equivalent replacement, modification or partial replacement of the present application without departing from the spirit and scope of the present application should be covered within the scope of the present application.
