[0023] like Figs. 1 to 4 As shown, the environmentally friendly heat radiation explosion-proof tunnel furnace of this embodiment includes a shell 1, a feed port 8 is provided at one end of the shell 1, a baffle 4 is provided on the front of the feed port 8, a conveyor belt 2 is installed in the middle of the shell 1, and a plurality of heat reflective films 3 are covered on the surface of the conveyor belt 2, a plurality of inspection ports 11 are provided at the top of the shell 1, a cover plate 9 is provided on the top of the inspection port 11, a plurality of clips 10 are fixedly connected to one side wall of the cover plate 9, a slide groove 16 is provided at the top of the inner side of the shell 1, a slide 14 is provided on the inner side of the slide groove 16, a plurality of radiation heating tubes 12 are installed on the inner wall of the slide 14, and a discharge port 17 is provided at the other end of the shell 1.

[0024] Specifically, the shell 1 is made of a material with good heat insulation performance, which can reduce the heat loss through the shell 1, thereby reducing unnecessary heat loss. The baffle 4 can push the material to be baked onto the heat-reflecting film, so that the heat-reflecting film can reflect heat smoothly on the surface of the material, thereby improving the heat utilization efficiency of the tunnel furnace and being more energy-saving and environmentally friendly. The conveying belt 2 is in the form of a mesh belt, which can better support the heat-reflecting film 3. The heat-reflecting film 3 is made of a flexible material, which can smoothly rotate at the end of the mesh belt, thereby reducing the probability of breaking of the heat-reflecting film 3. The sizes of the plurality of access openings 11 are the same, and the initial positions of the radiant heating pipes 12 of the sliding frame 14 are staggered, thereby ensuring that the radiant heating pipes 12 can be covered by the top of the shell 1 to reduce heat loss of the radiant heating pipes 12. The cover plate 9 covers the access opening 11, and cooperates with the clamping strip 10 on the side to make the clamping strip 10 fit into the corresponding access opening 11 when the cover plate 9 is tightly covered on the top of the shell 1, so that the top of the shell 1 is in a closed state, thereby ensuring that the heat stays in the tunnel furnace. The sliding groove 16 enables the sliding frame 14 to smoothly slide in the shell 1.

[0025] Further, the vertical frame 5 is arranged on the top of one end of the conveying belt 2 at the feeding port 8, the first electric push rod 6 is fixedly installed at the top end of the vertical frame 5, and the vertical frame 5 supports the first electric push rod 6, so that the first electric push rod 6 can drive the baffle 4 to slide up and down on the top of the conveying belt 2, thereby intercepting the material on the conveying belt 2.

[0026] Further, the output end of the first electric push rod 6 is fixedly connected with the baffle 4, and the baffle 4 is slidably connected with the vertical frame 5 through the first electric push rod 6. The baffle 4 can push the material on the conveying belt 2 to the heat-reflecting film 3, so that the heat reflected by the heat-reflecting film 3 can be conducted to the surface of the material, thereby facilitating the material to timely absorb sufficient heat.

[0027] Further, the two sides of the bottom of the cover plate 9 are fixedly connected with the rotating rods, and the cover plate 9 is rotatably connected with the shell 1 through the rotating rods. The rotating rods enable the cover plate 9 to be flipped open at the top end of the shell 1, thereby opening the access opening 11.

[0028] Further, the timing controller 7 is installed on one side of the top end of the vertical frame 5, and the timing controller 7 is electrically connected with the first electric push rod 6. The timing controller 7 can control the lifting time of the first electric push rod 6, so that the first electric push rod 6 can be lifted within a set time, thereby facilitating the control of the baffle 4 by the first electric push rod 6, and enabling the baffle 4 to smoothly push the material to the heat-reflecting film 3.

[0029] Further, the second electric push rod 13 is fixedly installed on the inner top of the shell 1 near one side of the feeding port 8, the output end of the second electric push rod 13 is fixedly connected with one side wall of the sliding frame 14, the second electric push rod 13 can push the sliding frame 14, so that the sliding frame 14 can slide in the sliding groove 16, so that the radiation heating pipe 12 originally dislocated with the maintenance opening 11 can slide to the directly below the maintenance opening 11, thereby facilitating the maintenance personnel to maintain the radiation heating pipe 12.

[0030] Further, the sliding frame 14 is slidably connected with the sliding groove 16 through the pulley 15, the pulley 15 is installed at the four corners of the bottom end of the sliding frame 14, the pulley 15 can make the sliding frame 14 slide in the sliding groove 16 more smoothly, thereby facilitating the sliding of the sliding frame 14 in the sliding groove 16.

[0031] The use method of the embodiment is as follows: when the environment-friendly heat radiation type explosion-proof tunnel furnace is used, the tunnel furnace needs to be connected with an external power supply first, then the materials are placed on the conveying belt 2, then the timer controller 7 can be set to a corresponding time according to the frequency of placing the materials and the conveying rate of the conveying belt 2, so that the baffle 4 can push the materials placed on the conveying belt 2 to the corresponding heat reflecting film 3 under the lifting action of the electric push rod, then the materials staying on the heat reflecting film 3 will enter the inside of the shell 1 along with the conveying belt 2 to be baked, when the radiation heating pipe 12 in the shell 1 radiates heat to the materials and the surroundings of the materials, the heat reflecting film 3 can reflect the heat around the materials to the surface of the materials again, so that the materials can timely and sufficiently absorb the heat, thereby reducing the loss of heat during the heat transfer in the furnace, when the radiation heating pipe 12 in the tunnel furnace needs to be maintained, the cover plate 9 is opened to make the maintenance opening 11 open, then the second electric push rod 13 is started to make the second electric push rod 13 push the sliding frame 14 to slide in the sliding groove 16, so that the radiation heating pipe 12 on the sliding frame 14 slides to the below of the corresponding maintenance opening 11, at this time, the radiation heating pipe 12 can be detached from the sliding frame 14 through the maintenance opening 11 to be checked and maintained or replaced.
