The working principle of the technical scheme is as follows:
according to the demand condition of the coagulant, the preparation of the coagulant is preferentially ensured, and when the coagulant bin is full, the mode is automatically switched to a recycling mode, specifically:
1. when the material level in the accelerator using bin 12 is higher than the middle material level, the system automatically recognizes that the accelerator storage capacity is enough, and automatically switches to the recycling mode. At the moment, the first pipe chain machine 3 is started, the first flashboard is opened, the materials (dust collection ash/three-control dust collection ash) output by the first discharge port are conveyed to the belt conveyor 2 through the first pipe chain machine 3, and the desulfurized gypsum enters the calcining system through the belt conveyor 2.

At the moment, the first pipe chain machine 3 and the second pipe chain machine 5 are started, the second flashboard is opened, and the first flashboard is closed. The materials (dust collection ash) output from the second discharge port are conveyed through the second pipe chain machine 5, the dust collection ash is lifted into the powder selecting screen 4, the extracted small-particle gypsum is conveyed into the raw material bin 6 through the third pipe chain machine 7, and the screened paper scraps, large-particle gypsum and superfine gypsum powder are not beneficial to preparation and use of a coagulant, and are conveyed into the first pipe chain machine 3, conveyed onto the belt conveyor 2 through the first pipe chain machine 3, and enter a calcining system through the belt conveyor 2 to be calcined and recycled. The small-particle gypsum entering the raw material bin 6 through the third pipe chain machine 7 is mixed with grinding aids such as starch and the like, and then enters the ball mill 9 through the fourth pipe chain machine 8 for grinding to prepare the coagulant.
The beneficial effects of the above technical scheme are:
1. in the invention, the dust collection ash can preferentially ensure the preparation of the coagulant according to the requirement condition of the coagulant; when the coagulant bin is full, the mode is automatically switched to the recycling mode. Therefore, the full-automatic recycling of the collected dust can be effectively realized, and the comprehensive utilization of the three-control collected dust can be realized.
2. The invention adopts full-automatic production, can greatly reduce the workload of workers in the preparation process of the coagulant and improve the production efficiency.
3. Through the mode of conveying the dust collection ash to the belt conveyor 2, the dynamic mixing of the dust collection ash and the desulfurization gypsum in a fixed proportion can be realized, and a very good mixing effect is achieved.
4. The prepared coagulant of the ball mill 9 enters the coagulant using bin 12 along the conveying pipeline 10 through pneumatic conveying of the Roots blower 11, so that the whole preparation process of the coagulant is completed, the manual operation time is saved, and the production efficiency is greatly improved.
