[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-6 This utility model provides the following technical solution: an automated hot air circulating tunnel furnace, including a furnace body 1, with multiple conveying rods 2 rotatably connected to the inner wall of the furnace body 1, and two conveying wheels 3 rotatably connected to the inner wall of the furnace body 1. A filter belt 31 is sleeved on the outer side of the two conveying wheels 3, and an air collecting groove 4 is provided on the inner wall of the filter belt 31. A dust collecting groove 5 is provided at the bottom of the filter belt 31. The other ends of the air collecting groove 4 and the dust collecting groove 5 are connected to a first air collecting pipe 6, and one end of the air collecting groove 4 is connected to a second air collecting pipe. The outer sides of the pipe 7, the air collecting trough 4, the dust collecting trough 5, the first air collecting pipe 6, and the second air collecting pipe 7 are fixedly connected to the inner side wall of the furnace body 1. The top inner wall of the dust collecting trough 5 is slidably connected to two first dust collecting trays 51. The inner side wall of the dust collecting trough 5 is also slidably connected to a second dust collecting tray 52. ​​The bottom inner wall of the second dust collecting tray 52 is fixedly installed with a filter screen 53. The outer sides of the first dust collecting tray 51 and the second dust collecting tray 52 are slidably connected to the inner side wall of the furnace body 1. The inner walls on both sides of the furnace body 1 are interlaced with input pipes 10.

[0025] In practical use, when using the tunnel furnace, air is introduced into the furnace body 1 through the input pipe 10. The conveyor rod 2, when rotating, is used to input and output objects to be processed into the furnace body 1. Inside the furnace body 1, the conveyor wheel 3 drives the filter belt 31 to rotate. The filter belt 31 filters the circulating hot air inside the furnace body 1, allowing it to be driven to the dust collection trough 5. The first dust collection tray 51 then scrapes and cleans the surface dust. As the filter belt 31 continues to move, the filter screen 53 inside the second dust collection tray 52 removes any remaining dust adhering to the filter belt 31. The filtered air can be further extracted and collected inside the second dust collection tray 52, while the filtered air is output from inside the dust collection trough 5, thereby improving the convenience of the overall tunnel furnace for collecting filtered dust. The air filtered by the filter belt 31 inside the furnace body 1 can be further collected through the air collection trough 4 and the first air collection pipe 6 and the second air collection pipe 7 at both ends, and the air filtered by the filter screen 53 inside the dust collection trough 5 is further collected through the second air collection pipe 7, so that the filtered air is output to the top of the furnace body 1 after filtration, thereby achieving the effect of circulating the airflow inside the furnace body 1.

[0026] Preferably, the outer sides of the first air collection pipe 6 and the second air collection pipe 7 are connected to multiple conveying pipes 8, the top inner wall of the furnace body 1 is fixedly installed with an air outlet pipe 9, the two sides of the air outlet pipe 9 are connected to the top of the conveying pipe 8, the bottom end of the air outlet pipe 9 is connected to multiple exhaust hoods 91, and the inner side wall of the air outlet pipe 9 is fixedly installed with an electric heating wire 92.

[0027] In practical use, after the first air collecting pipe 6 and the second air collecting pipe 7 inside the furnace body 1 filter and collect the air, it can be transported from the conveying pipe 8 to the air outlet pipe 9 at the top of the furnace body 1. After being heated by the electric heating wire 92 inside the air outlet pipe 9, it is output downward from the exhaust hood 91, thereby achieving the effect of circulating the airflow inside the furnace body 1.

The outer side of the first motor 57 is fixedly connected to the inner side wall of the dust collection tank 5.

[0029] In practical use, when it is necessary to further remove the dust attached to the filter belt 31, the first motor 57 can drive the guide rod 54 to rotate inside the dust collection tank 5, which can suck up the dust attached to the filter belt 31 and collect it inside the second dust collection tray 52 through the action of the filter screen 53.

[0030] Preferably, both ends of the conveyor rod 2 are fixedly installed with linkage wheels 21, and linkage belts 22 are sleeved on the outer side of the linkage wheels 21. One end of one of the conveyor rods 2 is fixedly installed with a drive motor 23, and the outer side of the drive motor 23 is fixedly connected to the inner side wall of the furnace body 1.

[0031] In practical use, when it is necessary to input or output objects into or out of the furnace body 1 via the conveyor rod 2, the drive motor 23 can drive the conveyor rod 2 to rotate, and through the action of the linkage wheel 21 and the linkage belt 22, the conveyor rod 2 can be used to convey objects.

[0032] Preferably, a second motor 32 is fixedly installed on the outside of the furnace body 1, and the output end of the second motor 32 is fixedly connected to one end of the conveyor wheel 3.

[0033] In practical use, the conveyor wheel 3 can be driven to rotate by the second motor 32, thereby driving the filter belt 31 to filter the hot air.

[0034] Preferably, a linkage handle 58 is fixedly installed at one end of the first dust collection drawer 51 and the second dust collection drawer 52.

[0035] In practical use, the linkage handle 58 can simultaneously pull the first dust collection tray 51 and the second dust collection tray 52 out of the dust collection tank 5 and the furnace body 1, making it easier to remove dust.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
