[0020] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0021] like Figure 1 As shown, as a mixed gas uniform conveying device of the present invention, it includes a ventilation pipe 10, a ventilation member 20, a first air inlet pipe 30 and a second air inlet pipe 40. Hot air is introduced into the top of the ventilation pipe 10, and the first air inlet pipe 30 and the second air inlet pipe 40 are respectively connected to the two sides of the ventilation pipe 10. The first air inlet pipe 30 and the second air inlet pipe 40 are staggered. The first air inlet pipe 30 and the second air inlet pipe 40 are both arranged as a square structure. The first air inlet pipe 30 and the second air inlet pipe 40 are connected with the ventilation member 20. After the cold air is introduced into the ventilation member 20, it is transported to the first air inlet pipe 30 and the second air inlet pipe 40 at the same time.

[0022] Specifically, hot air is introduced into the top of the ventilation duct 10, and cold air is introduced into the first air inlet duct 30 and the second air inlet duct 40, and the hot and cold air are mixed inside the ventilation duct 10. Since the first air inlet duct 30 and the second air inlet duct 40 are located on both sides of the ventilation duct 10, and the first air inlet duct 30 and the second air inlet duct 40 are staggered, when the hot air circulates in the ventilation duct 10, the cold air introduced into the first air inlet duct 30 and the second air inlet duct 40 will mix with the hot air. Since the cold air is introduced into the high and low sides, the hot and cold air mixing effect can be improved, and when measuring the wind, the measurement result can be more accurate.

[0023] In addition, through this structural setting, when one of the first air inlet pipe 30 and the second air inlet pipe 40 is damaged, the other one can still be used, avoiding the situation where one of the two is damaged and cannot be used.

[0024] like Figure 2 As shown, the first air inlet pipe 30 and the second air inlet pipe 40 have the same structure. A plurality of partition plates 33 are provided inside the first air inlet pipe 30 on one side of the ventilation pipe 10. The partition plates 33 separate the first air inlet pipe 30 into a plurality of conveying channels 31, and a porous plate 32 is provided in each conveying channel 31.

[0025] The length of the first air inlet pipe 30 is equal to that of the ventilation pipe 10 .

[0026] Specifically, by setting up multiple conveying channels 31, the air delivered to the first air inlet duct 30 or the second air inlet duct 40 can pass through the multiple conveying channels 31 evenly, so that the air entering the ventilation duct 10 is more evenly distributed and the mixing effect with the hot air is better; in addition, by setting up the porous plate 32, the distribution of the cold air entering the ventilation duct 10 can also be more evenly distributed; the length of the first air inlet duct 30 is equal to the length of the ventilation duct 10, which can make the first air inlet duct 30 and the second air inlet duct 40 mix with the hot air more quickly and more evenly when the cold air is passed in, and the actual application effect is better.

[0027] like Figure 1 As shown, a sealing plug 50 is provided on one end of the first air inlet pipe 30 and the second air inlet pipe 40 away from the ventilation pipe 10 , a through hole is opened inside the sealing plug 50 , and one end of the sealing plug 50 is connected to the ventilation member 20 .

[0028] Specifically, by providing the sealing plug 50 , the air introduced from the ventilation member 20 can be evenly introduced into the first air inlet pipe 30 and the second air inlet pipe 40 , while preventing the transported air from leaking out.

[0029] like Figure 3 As shown, the ventilation member 20 includes an air inlet bin 21 and a right-angle connecting pipe 22. Both sides of the air inlet bin 21 are connected with a right-angle connecting pipe 22, and the right-angle connecting pipes 22 on both sides are connected to the first air inlet pipe 30 and the second air inlet pipe 40 respectively.

[0030] Cold air enters from the air inlet bin 21, and is respectively transported to the first air inlet duct 30 and the second air inlet duct 40 through the right-angle connecting pipe 22, and cold air is introduced from both sides of the ventilation duct 10. This structural setting allows the cold air introduced into the ventilation duct 10 to be input at the same time, so that the mixing effect of cold and hot air inside the ventilation duct 10 is better.

[0031] The ventilation duct 10 is configured as a right-angle structure, with an arc-shaped guide plate 60 provided at a right-angle position in the ventilation duct 10, a mesh plate 70 provided at the bottom of the ventilation duct 10, and a detection device 80 provided on the rear side of the mesh plate 70 in the ventilation duct 10. Through this structural setting, the detection device 80 can detect the data of the mixed wind more accurately, completely solving the problem of inaccurate measurement of the primary air volume at the coal mill inlet, and improving the safety and economy of the coal mill operation.

[0032] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
