[0019] A coal gangue decarbonization device includes a base 1 and a decarbonization box 2 installed on the base 1. The two sides of the decarbonization box 2 are connected to the base 1 through support frames 3. A recycling frame 4 is symmetrically installed on the top of the support frame 3. A first discharge port 5 and a second discharge port 6 are symmetrically opened on both sides of the bottom of the decarbonization box 2, and a third discharge port 8 is opened at the bottom. An air inlet pipe 7 and a rotating assembly for driving the air inlet pipe 7 are installed on the top of the decarbonization box 2. A feed hopper 9 connected to the inside of the air inlet pipe 7 is installed on one side of the air inlet pipe 7. One end of the air inlet pipe 7 extends into the decarbonization box 2 and a first filter plate 10 and a second filter plate 11 are installed in sequence. A plurality of air outlet holes 12 are opened in the decarbonization box 2.
[0020] In use, coal gangue can be added into the decarbonization chamber 2 through the feed hopper 9, and then pass through the first filter plate 10 and the second filter plate 11 in sequence. The rotating assembly is started to drive the air inlet pipe 7, the first filter plate 10 and the second filter plate 11 to rotate, and perform grading and screening. High-temperature gas can enter the decarbonization chamber 2 through the air inlet pipe 7 and be discharged through several air outlets 12 to contact the coal gangue in the decarbonization chamber 2, thereby increasing the contact area and making the contact between the coal gangue and the high-temperature gas more sufficient, thus improving the decarbonization effect of the coal gangue. This achieves the purpose of decarbonizing and screening the coal gangue at the same time, eliminating the need for separate screening equipment and improving the efficiency of coal gangue screening and decarbonization.

[0022] The diameter of the filter holes on the first filter plate 10 is larger than that on the second filter plate 11, thus achieving the purpose of graded screening.
[0023] The first discharge port 5, the second discharge port 6, and the third discharge port 8 are all equipped with sealing plates.
[0024] After the coal gangue screening and decarbonization work is completed, the pull plate can be pulled out to allow the screened coal gangue of different particle sizes to enter the first collection box 13 and the second recycling box 14 through the first discharge port 5, the second discharge port 6 and the third discharge port 8 respectively for classified recycling. It should be noted that the first filter plate 10 and the second filter plate 11 are installed at an angle on the outside of the air inlet pipe to facilitate material discharge.
