[0002] Phosphogypsum hydraulic curing agent is mainly composed of phosphogypsum, ordinary cement, alkaline slag, lime and curing agent. In the processing, phosphogypsum needs to be treated. First, the moisture content of phosphogypsum needs to be adjusted to a suitable range, and then it needs to be crushed, ground and processed. Then, the various raw materials are mixed evenly in a certain proportion.

[0003] Existing conveyor lines can only transport phosphogypsum, making it difficult to process the phosphogypsum during the transport process. It needs to be transported to specific equipment for processing and undergo multiple transfers to process the phosphogypsum to the required state.

[0004] Therefore, a conveyor line for the production of phosphogypsum hydraulic curing agent is proposed. Utility Model Content

A breaking surface is provided on the outer wall of the heating plate 18.

[0024] It should be noted that existing conveyor lines can only transport phosphogypsum, making it difficult to process the phosphogypsum during the transport process. It is necessary to transport it to specific equipment for processing and transfer it multiple times to process the phosphogypsum to the required state. In this embodiment, the phosphogypsum rolls along the inclined guide seat 3 under its own gravity, and in conjunction with the rolling table 5, crushing table 11 and grinding roller, the phosphogypsum can be rolled, crushed and ground. The processing of the phosphogypsum to the state required by the curing agent can be achieved in one step, without the need for multiple equipment, reducing the number of transfers and improving the efficiency and convenience of phosphogypsum processing. Furthermore, the phosphogypsum on the upper belt conveyor 2 is subjected to separate heat treatment by the heating plate 18, which can uniformly reduce the moisture content of the phosphogypsum, thereby providing conditions for the subsequent processing of phosphogypsum.

[0025] Specifically, in this embodiment, the scheme mainly includes a rolling table 5, a crushing table 11, a lower grinding roller 15, and an upper grinding roller 16. When conveying phosphogypsum, the phosphogypsum is linearly conveyed via an upper belt conveyor 2. A heating plate 18 contacts the phosphogypsum on the upper belt conveyor 2, and the heating plate 18 heat-treats the phosphogypsum. By heating the phosphogypsum, its moisture content is reduced, and the heating temperature of the heating plate 18 is controlled to avoid adverse effects on the properties of the phosphogypsum material. The upper belt conveyor 2 conveys the phosphogypsum with controlled moisture content to an inclined guide seat 3. Since one side of the inclined guide seat 3 is inclined, the phosphogypsum rolls downwards on the inclined guide seat 3. The hydraulic cylinder 8 drives the connecting block 9 to reciprocate linearly through its output end on one side. The rolling table 5 is rotatably connected to the frame 1, and the connecting block 9 and the connecting frame 6 are rotatably connected. The rolling table 5 is pushed to move back and forth towards the inclined guide seat 3. The rolling table 5 crushes the phosphogypsum rolling on the inclined guide seat 3. The control hydraulic cylinder 10 drives the crushing table 11 to move back and forth through its output end on one side. The crushing cone 12 on the crushing table 11 moves towards the phosphogypsum and crushes it. The crushed phosphogypsum rolls between the lower grinding roller 15 and the upper grinding roller 16. The control motor 14 drives the lower grinding roller 15 to rotate through its output end on one side. Under the gear meshing transmission, the lower grinding roller 15 and the upper grinding roller 16 rotate towards each other. The lower grinding roller 15 and the upper grinding roller 16 grind the phosphogypsum. The ground phosphogypsum falls to the lower belt conveyor 4 and is finally transported away by the lower belt conveyor 4.

[0026] In a further preferred embodiment of this utility model, such as Figure 3 As shown, an inclined surface at a 45-degree angle to the horizontal plane is provided on one side of the outer wall of the inclined guide seat 3, and a plane that is horizontal to the inclined guide seat 3 is provided on one side of the outer wall of the rolling table 5.

[0027] In this embodiment, the 45-degree inclined surface ensures that the phosphogypsum on the inclined guide seat 3 falls smoothly, avoiding the accumulation of phosphogypsum, and the rolling table 5 and the part of the inclined guide seat 3 that are horizontal with each other can effectively roll the phosphogypsum.

[0028] In a further preferred embodiment of this utility model, such as Figure 3 As shown, an arc groove is provided on the outer side wall of the inclined guide seat 3 near the outer side of the lower grinding roller 15, and a part of the lower grinding roller 15 protrudes out of the arc groove.

[0029] In this embodiment, phosphogypsum can be ground by the lower grinding roller 15 and the upper grinding roller 16 rotating in opposite directions.
