Description

Technical Field

[0001] The utility model relates to the technical field of phosphogypsum processing, in particular to a phosphogypsum inerting treatment device. Background Art

[0002] As a major by-product in the production of phosphate fertilizers, phosphogypsum has a huge annual output. If it is not properly handled, it will cause serious pollution to the environment. The main component of phosphogypsum is calcium sulfate dihydrate, and it also contains soluble impurities such as incompletely decomposed phosphates, fluorides, organic matter, and heavy metal ions. The presence of these impurities not only limits the application of phosphogypsum in building materials, soil conditioners and other fields, but may also cause secondary pollution to the environment during the utilization process. With the enhancement of environmental awareness and the continuous development of resource utilization technology, people have put forward higher requirements for the inerting treatment technology of phosphogypsum. Inerting treatment is to convert the soluble impurities in phosphogypsum into insoluble or harmless substances through physical, chemical or biological methods, thereby reducing its harm to the environment and increasing the reuse value of phosphogypsum. When inerting phosphogypsum, it is usually necessary to add inerting substances and mix them with phosphogypsum to remove soluble impurities such as phosphorus, fluorine, and organic matter in phosphogypsum.

[0003] Chinese patent CN221230447U discloses a phosphogypsum inerting treatment device, comprising an inerting treatment mechanism fixedly mounted vertically on a frame. The inerting treatment mechanism comprises a feed section, a mixing section, and a grinding section, which are coaxially flanged from top to bottom. The feed section comprises a feed pipe and a motor. The sidewall of the feed pipe is provided with feed ports distributed along an inclined direction. The top flange of the feed pipe is connected to a sealing plate. The motor is fixedly mounted on the top of the sealing plate. The output end of the motor passes through the sealing plate and is coaxially fixedly connected to a shaft. The mixing section comprises an upper cone and a lower cone. This phosphogypsum inerting treatment device has the following drawbacks: phosphogypsum is a solid particle and is prone to agglomeration. Before being introduced into the mixing equipment, the phosphogypsum will contain a large number of agglomerates, which makes it difficult for the agglomerated phosphogypsum to fully mix with the inerting material during stirring, reducing the effectiveness of the inerting treatment. Utility Model Content

[0004] The utility model aims to solve the above problems existing in the prior art phosphogypsum inerting treatment device and provides a phosphogypsum inerting treatment device with a simple structure and good stirring and mixing effect.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the present invention provides an inerting treatment device for phosphogypsum, comprising a stirring mechanism and a pretreatment mechanism assembled on the top of the stirring mechanism; the pretreatment mechanism comprises a pretreatment box fixedly mounted on the top of the stirring mechanism and a roller rotatably mounted in the pretreatment box, the surface of the roller is evenly distributed with crushing teeth in a ring array, the interior of the pretreatment box is fixedly mounted with teeth staggered with the crushing teeth, a leakage hole is provided on the surface of the roller adjacent to the crushing teeth, a fixing rod is fixedly mounted on the interior of the roller, and two symmetrically distributed fixing columns are rotatably mounted on the bottom of the fixing rod through a rotating sleeve, and a material guide plate is fixedly mounted on the bottom of the two fixing columns. Based on the above-mentioned structural setting, the phosphogypsum inerting treatment device is composed of a hinged pretreatment mechanism and a hinged stirring mechanism. The hinged pretreatment mechanism can facilitate the crushing operation of the lumps in the phosphogypsum. At the same time, during the crushing process, the inerting material can be pre-mixed with the crushed phosphogypsum, which can effectively improve the subsequent mixing reaction effect, enable it to be quickly and fully mixed, and enhance the treatment effect of the phosphogypsum.

[0006] Preferably, a counterweight is fixedly mounted on the outside of the fixed column, and a cleaning brush corresponding to the material leakage hole is fixedly mounted on the bottom of the material guide plate. The counterweight can generate a gravity effect, which can keep the fixed column in a vertical position at all times without affecting the rotation of the roller. When the roller rotates, the cleaning brush can extend into the material leakage hole, ejecting material stuck in the leakage hole and preventing the leakage hole from becoming clogged.

[0007] Preferably, a storage box is fixedly mounted on the top of the pretreatment box, with the bottom of the storage box extending into the pretreatment box and abutting the top of the roller. By introducing the inerting material into the storage box for storage, the inerting material can be evenly introduced into the roller through the material leakage holes during the rotation of the roller, facilitating the inerting material to be scattered onto the crushed phosphogypsum for premixing.

[0008] Preferably, the stirring mechanism comprises a stirring box fixedly mounted on the bottom of the pretreatment box, wherein a door is hingedly mounted on the bottom of the stirring box. By closing the door, the door and the stirring box can form an integrated effect, so that the material can be stirred in the stirring box.

[0009] Preferably, a stirring rod is rotatably mounted inside the mixing box, and a second motor corresponding to the stirring rod is fixedly mounted on one side of the mixing box. The second motor can provide power to the stirring rod, driving the stirring rod to rotate. The stirring rod is provided with a plurality of stirring blades, so that when the stirring rod rotates, the material can be fully stirred and mixed.

[0010] Preferably, a material guide pipe is fixedly installed between the pretreatment box and the mixing box, and a first motor corresponding to a rotating roller is fixedly installed at the front end of the pretreatment box. After the phosphogypsum is pretreated in the pretreatment box, it can be introduced into the material guide pipe. The material guide pipe can guide the pretreated phosphogypsum into the mixing box for stirring and mixing. The first motor can provide power to the rotating roller, which can conveniently drive the rotating roller to rotate and facilitate the crushing of agglomerated phosphogypsum.

[0011] Therefore, the utility model has the following beneficial effects: by providing a pretreatment mechanism, the agglomerated phosphogypsum can be pre-crushed by the rolling action of the roller; during the crushing process, the inerting material can be introduced into the roller through the storage box; the inerting material can be scattered on the surface of the crushed phosphogypsum through the leakage hole; the phosphogypsum can be effectively pre-mixed with the inerting material when it is crushed; the subsequent stirring and mixing effect can be effectively improved, so that the phosphogypsum can be fully mixed and reacted with the inerting material, which brings more convenience to the processing of the phosphogypsum.

A storage box 105 is fixedly installed on the top of the pretreatment box 102. The bottom of the storage box 105 extends into the pretreatment box 102 and fits on the top of the roller 3. The inert material can be conveniently stored through the storage box 105. The surface of the roller 3 is provided with a leakage hole 302 adjacent to the crushing tooth 301.
