Since the main component of calcite is calcium carbonate, it is crushed and mixed with PP or PE according to a certain formula to make calcite stone paper. However, PP or PE are non-degradable plastics, and the application range of the finished paper products is limited because they contain non-degradable components. Summary of the invention

An intelligent fully automatic phosphogypsum papermaking method, characterized in that: The intelligent fully automatic phosphogypsum papermaking system according to any one of claims 1 to 9 comprises the following steps: S1: The phosphogypsum is fed to the dehumidification mechanism after the feeding amount is quantitatively controlled by the feeding mechanism, and then dehumidified by the dehumidification mechanism; S2: The dehumidified phosphogypsum is sent to a foreign matter removal mechanism to remove magnetic metal foreign matters and non-magnetic metal and non-metal foreign matters, and the removed foreign matters are sent to a foreign matter collection mechanism; S3: The phosphogypsum after foreign matter is removed is sent to the sorting mechanism for particle size refinement; S4: the phosphogypsum powder after the particle size refinement treatment is fed into the batching mechanism, the adhesive dispensing device and the auxiliary agent dispensing device respectively feed the biodegradable material and the auxiliary agent into the batching mechanism, and the phosphogypsum powder is mixed with the biodegradable material and the auxiliary agent in the batching mechanism; S5: The deep refining mechanism sets different refining time, temperature, pressure and pressure holding time according to the requirements of different paper products to refine the mixed material and transport it to the granulation mechanism; S6: The granulation mechanism draws the mixed material into wires according to the requirements of different paper products and cuts the granular materials of different sizes; S7: The rapid cooling mechanism cools the pellets; S8: The cloth mechanism converts the cooled granular material into a blank for a finished paper product; S9: the coating mechanism performs corresponding surface treatment on the paper blank from the coating mechanism according to different final uses; S10: The receiving mechanism winds up the coated paper products of different thicknesses together; S11: The slitting mechanism cuts the wound paper product into roll units according to different roll sizes; S12: The warehouse transport robot transports the roll unit to the paper finished product warehouse; Among them, a testing organization and an environmentally friendly diluent distribution organization are also set between the foreign matter removal organization and the classification organization. The testing organization is used for online sampling to detect whether the heavy metal content and radioactive element content of phosphogypsum are within the environmental protection range. The test data of the testing organization is transmitted to the environmentally friendly diluent distribution organization. If the data meets the standard, the environmentally friendly diluent distribution organization does not take any action. If the data exceeds the standard, the environmentally friendly diluent distribution organization distributes different amounts of diluents according to the excess amount to ensure that the incoming materials of the batching organization are within the environmental protection compliance range.
