Description

Technical Field

[0001] The present invention relates to the technical field of phosphogypsum purification, in particular to phosphogypsum flotation purification equipment for preparing calcium sulfate hemihydrate whiskers and a use method thereof. Background Art

[0002] There are mainly two types of phosphogypsum: gray-black and gray-white. Phosphogypsum is a solid waste produced in the wet phosphoric acid process. Its main component is calcium sulfate dihydrate. The composition of phosphogypsum is relatively complex. In addition to calcium sulfate, there are also incompletely decomposed phosphate rock, residual phosphoric acid, fluoride, acid-insoluble matter, organic matter, etc. Among them, the presence of fluorine and organic matter has the greatest impact on the resource utilization of phosphogypsum. The random discharge and accumulation of phosphogypsum has seriously damaged the ecological environment, not only polluting groundwater resources, but also causing waste of land resources. It can be utilized after purification, and flotation equipment can usually be used for purification.

[0003] However, there are still some problems when using the existing phosphogypsum flotation purification equipment:

[0004] 1. When using existing phosphogypsum flotation purification equipment, when preparing hemihydrate calcium sulfate whiskers, it is necessary to manually mix water and phosphogypsum and further process them. The mixing ratio is difficult to control and is prone to errors. At the same time, after the mixing is completed, the reagents need to be added manually. The equipment is not automated enough, the labor is high, and it is inconvenient to use.

[0005] 2. The existing phosphogypsum flotation purification equipment is inconvenient to clean the impurities floating on the page after collecting them, which takes a lot of time and has low work efficiency. At the same time, the inner wall of the equipment cannot be cleaned. After use, phosphogypsum will adhere to the inner wall of the equipment, which will not only corrode the inner wall of the equipment, but also affect the preparation effect of hemihydrate calcium sulfate whiskers when used next time.

[0034] Preferably, the method of use comprises the following steps:

[0035] Step 1: Mix water and phosphogypsum;

[0036] Water is injected into the proportioning box through the water inlet pipe, which drives the impeller provided at the lower end of the proportioning box to rotate, and at the same time drives the spiral rod connected to the upper end to rotate synchronously, so that the phosphogypsum stored in the storage box can be transported to the inside of the device body through the proportioning pipe.

[0044] 1. By injecting water into the device, and when the water flows through the proportioning box through the water inlet pipe, it can drive the impeller to rotate. The impeller drives the screw rod to rotate, which can transport the phosphogypsum in the storage box through the proportioning pipe to the inside of the device body. The phosphogypsum and water can be automatically proportioned according to the proportion while the water is injected, which reduces labor and is more convenient to use.

[0045] 2. The motor drives the stirring rod to rotate and at the same time drives the first transmission wheel to rotate. The first transmission wheel drives the second transmission wheel to rotate through the belt, and drives the movable block inside the fixed block to rotate synchronously. The movable block drives the roller to rotate to continuously squeeze the hose, which can transport the mixed liquid in the liquid storage tank to the inside of the device body without manual adjustment of the liquid;

[0046] 3. The motor rotates in the opposite direction to drive the rotating rod to rotate, and drives the collecting net to rotate synchronously. The collecting net is connected to one side of the rubber sheet to collect impurities floating on the liquid surface. After use, the collecting net can be directly disassembled and the cleaned collecting net can be installed, which can save the time of cleaning the collecting net. The removed cleaning net can be cleaned more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS
