A first chute is formed on two vertical wall plates arranged opposite to each other on the material storage part, and a second chute is formed on the wall plate of the sintering part. The loading assembly is composed of two first push rods 23, a first flap 25 and a first rotating rod 27. The two first push rods 23 are respectively arranged on the outer sides of the material storage part. After the first rotating rod 27 passes through the first chute, its two ends are respectively connected to the two first push rods 23. The first push rod 23 is movably connected, and a through hole is respectively opened on the first push rod 23, and the first rotating rod 27 is inserted into the through hole. The rotating motor is arranged outside the material storage part, and the rotating motor is connected to the first rotating rod 27. The first flap 25 is arranged inside the material storage part and is sleeved on the first rotating rod 27. The first flap 25 moves along the inside of the material storage part, and the first rotating rod 27 is slidably connected along the first slide groove. The pushing motor 22 is connected to the first push rod 23 for driving the first push rod 23 to move; the unloading assembly includes two second push rods 24, a second flap 26 arranged between the two second push rods 24, and a second rotating rod 28 that penetrates the second flap 26. The unloading assembly is installed in the same manner as the loading assembly. The installation position of the unloading assembly is in the sintering part. A connecting rod is arranged between the first rotating rod 27 and the second rotating rod 28. When the rotating motor drives the first rotating rod 27 to rotate, the first rotating rod 27 synchronously drives the second rotating rod 28 to rotate through the connecting rod, so as to realize the synchronous movement of the first flap 25 and the second flap 26;When in use, the first push rod 23 drives the first flap 25 to be vertically arranged at the opening of the material storage part close to the first conveyor belt 12. At this time, the first conveyor belt 12 conveys the mixture to the material storage part, and the first flap 25 is used to block the opening of the material storage part to prevent the mixture from scattering. At this time, the second push rod 24 drives the second flap 26 to be vertically inserted into the connection between the material storage part and the sintering part, so as to completely separate the material storage part and the sintering part.

The production process of a quick-setting agent according to claim 5, characterized in that: In step 1, the mixture is made from the following raw materials in parts by weight: 20-35 parts of bauxite, 10-20 parts of sodium carbonate, 8-10 parts of calcium oxide, 10-25 parts of waste aluminum ash, and 5-10 parts of silicon powder. The above raw materials in parts by weight are sequentially put into a mixing device (1) and stirred for 3-10 minutes.

7. The production process of a quick-setting agent according to claim 5, characterized in that: In the step six, modified kaolin and bentonite can be added to the grinding device during grinding. The amount of modified kaolin added is 5%-8% of the mass of the accelerating agent block, and the amount of bentonite added is 3%-6% of the mass of the accelerating agent block.

8. The production process of a quick-setting agent according to claim 7, characterized in that: The modified kaolin is alkali-modified kaolin. The accelerating agent block, modified kaolin and bentonite are ground into powder in a grinder, then mixed by shaking and packed in bags for storage.
