DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-2 The specific implementation modes of the present invention are further described in detail.

[0018] When the present invention is actually implemented, Figure 1-2A phosphogypsum mixing station comprises a powder batching machine 1, an aggregate batching machine 2, a curing agent metering device 3, a conveying device, a mixing host and a finished product warehouse 9. When in use, the powder batching machine 1, the aggregate batching machine 2 and the curing agent metering device 3 can be flexibly placed according to the site, and are not limited to being placed in a sequential arrangement. In this embodiment, the conveying device comprises a first conveying device 4 and a second conveying device 5. The first conveying device 4 and the second conveying device 5 are both selected (but not limited to) belt conveyors, wherein the first conveying device 4 is used to convey each aggregate, that is, the first conveying device 4 is placed at the lower end of the discharge port of the powder batching machine 1 and the aggregate batching machine 2, so that the powder batching machine 1 and the aggregate batching machine 2 can stably distribute materials to the first conveying device 4 in a quantitative manner. The discharge end of the curing agent metering device 3 is also placed at the upper end of the first conveying device 4 for metering the admixture. In this embodiment, the curing agent metering device 3 is placed at the upper end of the first conveying device 4 for metering the admixture. The chemical agent metering device 3 uses a screw feeder or a vibrating feeder, that is, in this embodiment, the first conveying device 4 will simultaneously convey the divided material, aggregate and curing agent. By adopting the first conveying device 4 for feeding and conveying, the purpose of placing the powder batching machine 1, the aggregate batching machine 2 and the curing agent metering device 3 according to the site can be achieved. At the same time, in order to achieve continuous production, the powder batching machine 1 and the aggregate batching machine 2 adopt continuous quantitative feeding, and the curing agent metering device 3 performs interval metering and feeding of the curing agent according to the mix ratio, that is, in this embodiment, it also includes a curing agent storage tank 8, and the curing agent storage tank 8 is connected to the curing agent metering device 3. Preferably, the feed end of the curing agent metering device 3 is equipped with a screw conveyor connected to the curing agent storage tank 8, and the curing agent is fed into the curing agent metering device 3 through the screw conveyor, and the curing agent is fed to the first conveying device 4 after being measured by the curing agent metering device 3; The end of the first conveying device 4 is connected to the feeding end of the mixing main machine. By default, the mixing main machine is a continuous vibrating mixer, which uses a double-horizontal shaft recursive stirring device to stir the materials. After the materials enter from the feeding port of the mixing main machine, they are directly discharged from the discharging port of the mixing main machine through the stirring and pushing action of the stirring device. By default, in this embodiment, the mixing time of the mixed material needs to be designed according to the quality of the finished material. When the mixing time of a single mixing main machine is not enough, the mixing main machine can be selected to be two, namely, a first mixing main machine 6 and a second mixing main machine 7. The first mixing main machine 6 and the second mixing main machine 7 are connected in a high and low stacking manner. At the same time, the first mixing main machine The main machine 6 is located at a high position, and the end of the first conveying device 4 is connected to the feed port of the first mixing main machine 6, that is, each material first enters the first mixing main machine 6 and is initially mixed by the first mixing main machine 6, and the discharge port of the first mixing main machine 6 is connected to the feed port of the second mixing main machine 7, and the mixed material after the initial mixing will enter the second mixing main machine 7 for further mixing. In this embodiment, each material is continuously added, and the powder, aggregate and curing agent are first mixed according to the proportion on the first conveying device 4, and then put into the first mixing main machine 6 and the second mixing main machine 7 for continuous mixing. After the mixing is completed, the finished materials are mixed evenly, and the production is produced through continuous mixing, which greatly improves the production efficiency; In addition, the second conveying device 5 is placed at the lower end of the discharge port of the second mixing host 7 to realize the conveying of the finished materials. The end of the second conveying device 5 is connected to the feeding end of the finished product bin 9, that is, the finished materials after processing will be stored in the finished product bin 9. In this embodiment, the finished product bin 9 is a high-level bin, which is equipped with a unloading device to realize the loading of the finished materials into the tank truck. In addition, in the finished product after mixing, because there are aggregates, when it is transported by the second conveying device 5, in the process of falling from the second conveying device 5, the aggregates may be segregated due to the large inertia. Because, in this embodiment, the end of the second conveying device 5 is provided with an anti-separation device. The anti-segregation mechanism includes a discharge channel 10 installed at the end of the second conveying device 5. The finished materials transported on the second conveying device 5 will enter the discharge channel 10 and be discharged from the discharge channel 10. An adjusting material door 11 is hinged on the discharge channel 10. An iron chain 12 is connected between the adjusting material door 11 and the discharge channel 10 to meet the need to push open the adjusting material door 11 during the discharge of the finished products from the second conveying device 5, thereby offsetting the speed of the finished materials driven by the second conveying device 5. The iron chain 12 is used to limit the opening degree of the adjusting material door 11, which can be adjusted according to the actual production efficiency of the mixing host to ensure the stable transportation of the finished materials.
