Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices, specifically a stirring device for the harmless treatment of phosphogypsum. Background Technology

[0002] Phosphogypsum mainly comes in two colors: grayish-black and grayish-white. The particle diameter is generally 5–50 μm, and the water of crystallization content is 20%–25%. Phosphogypsum is a solid waste generated in the wet-process phosphoric acid production process, and its main component is calcium sulfate dihydrate. The composition of phosphogypsum is relatively complex, containing not only calcium sulfate but also incompletely decomposed phosphate rock, residual phosphoric acid, fluorides, acid-insoluble substances, and organic matter. The presence of fluorine and organic matter has the greatest impact on the resource utilization of phosphogypsum. The indiscriminate dumping and accumulation of phosphogypsum severely damages the ecological environment, polluting groundwater resources and wasting land resources. The treatment of phosphogypsum requires the use of a mixing device.

[0003] Chinese patent application CN221107052U discloses a crystallization stirring device for the harmless treatment of phosphogypsum modifiers. The device includes a cylinder with an inlet pipe and a outlet pipe connected to the upper and lower halves of one side of the cylinder, respectively. A connecting pipe is rotatably mounted at the center of the top of the cylinder, and several stirring rods are connected to the surface of the connecting pipe. Several through holes are formed on the surface of each stirring rod. An air pump is fixedly mounted on one side of the top of the cylinder. Through the structural design of the connecting pipe, stirring rods, through holes, air pump, and air outlet pipe, gas can be supplied to the connecting pipe via the air pump and air outlet pipe during stirring. This allows the gas to connect to the stirring rods and be ejected from the through holes, resulting in bubbles at the contact points between the through holes and the modifier crystallization, thereby effectively improving the stirring effect and solving the problem of poor stirring performance and blind spots in existing stirring devices.

[0004] However, the mixing effect of the phosphogypsum mixing devices disclosed above is generally poor, and there are often dead zones in the mixing process. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for the harmless treatment of phosphogypsum, in order to solve the problems of the general mixing effect and the presence of dead zones in existing phosphogypsum mixing devices.

[0006] To achieve the above objectives, the technical solution of this utility model is: a stirring device for the harmless treatment of phosphogypsum, comprising a stirring drum, a rotating ring movably mounted on the top of the stirring drum, a vertical frame fixedly mounted in the middle of the rotating ring, an adjusting cylinder mounted on one side of the vertical frame, and a stirring shaft movably mounted on the output end of the adjusting cylinder; a support frame fixedly mounted on the side of the vertical frame, a driven gear movably mounted on the bottom of the support frame, a plurality of protrusions provided in the middle of the driven gear, and a plurality of linkage grooves cooperating with the protrusions being formed on the outer wall of the stirring shaft; a stirring motor mounted on the other side of the vertical frame, and a driving gear meshing with the driven gear being mounted on the output end of the stirring motor.

[0007] As a further embodiment of this utility model: a limiting boss is provided on the top of the stirring cylinder, and a limiting groove that cooperates with the limiting boss is provided on the outer wall of the rotating ring; a gear ring is also installed on the top of the rotating ring, and a rotary motor is also installed on the outer wall of the stirring cylinder, and a drive gear that meshes with the gear ring is installed at the output end of the rotary motor.

[0008] As a further improvement of this utility model: the output end of the regulating cylinder is provided with a rotating seat, and the outer wall of the stirring shaft is provided with a limiting groove that cooperates with the rotating seat.

[0009] As a further improvement of this utility model: the bottom of the support frame is provided with an installation rail, and the top of the driven gear is provided with an installation groove that cooperates with the installation rail.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention allows for overall adjustment of the height of the stirring shaft via an adjustable cylinder. When the adjustable cylinder moves the stirring shaft, the driven gear and the stirring shaft remain in a linked state through the cooperation of the protrusion and the linkage groove. When the rotary motor drives the rotating ring to rotate as a whole, the stirring shaft can rotate while stirring. This design improves the stability and degree of freedom of the stirring device used for the harmless treatment of phosphogypsum. Attached Figure Description
