Description

Technical Field

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

[0002] In the comprehensive utilization of phosphogypsum, flotation is a commonly used process to separate useful minerals and impurities from the phosphogypsum, thereby improving its purity and utilization value. Before flotation, the phosphogypsum needs to be thoroughly mixed with the flotation collector so that the collector can be effectively adsorbed onto the surface of the target mineral, thus achieving selective separation of the mineral. However, existing mixing devices typically employ a single stirring structure, which makes it difficult to ensure sufficient contact and mixing between the phosphogypsum slurry and the flotation collector. This can easily lead to uneven concentration in certain areas, affecting flotation performance. In particular, the phosphogypsum particles have a certain degree of viscosity and are prone to agglomeration, further exacerbating the difficulty of mixing. At the same time, existing mixing devices require a long stirring time to achieve a certain mixing effect, resulting in high energy consumption and low production efficiency, which cannot meet the needs of large-scale industrial production. In addition, due to uneven mixing, excessive amounts of flotation collector are often added to ensure flotation performance, which not only increases production costs but may also have negative environmental impacts. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a reagent stirring device for phosphogypsum treatment, which can effectively and fully mix phosphogypsum slurry and flotation collector, greatly improving the efficiency of mixing and stirring operations.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pharmaceutical stirring device for phosphogypsum treatment, including a stirring tank, a vertical plate on the top of the stirring tank, a motor mounting base on the top of the vertical plate, a motor installed in the motor mounting base, a motor drive shaft pointing downward and connected to a rotating shaft, the rotating shaft extending into the stirring tank, and stirring blades on the rotating shaft located in the stirring tank. A rotating plate is provided on the rotating shaft above the stirring blade and inside the stirring tank. A receiving trough is provided inside the stirring tank above the rotating plate. The receiving trough includes a phosphogypsum slurry receiving chamber and a flotation collector receiving chamber. Both the phosphogypsum slurry receiving chamber and the flotation collector receiving chamber have material passage holes on their bottom surfaces that are in a straight line. The rotating plate is set close to the bottom surface of the receiving trough and has material distribution strip holes.

[0005] In a preferred embodiment, the receiving trough has a cylindrical body in the middle, through which the rotating shaft passes. A partition is provided inside the receiving trough, which divides the receiving trough into a phosphogypsum slurry receiving chamber and a flotation collector receiving chamber.

[0006] In a preferred embodiment, the side wall of the mixing tank is provided with a phosphogypsum slurry inlet pipe and a flotation collector inlet pipe, and the output ends of the phosphogypsum slurry inlet pipe and the flotation collector inlet pipe extend directly above the phosphogypsum slurry receiving chamber and the flotation collector receiving chamber, respectively.

[0007] In a preferred embodiment, a fixed cylinder is provided at the center of the rotating plate, and the rotating shaft passes through the fixed cylinder and is fixedly connected to the fixed cylinder.

[0008] In a preferred embodiment, the bottom of the mixing tank is provided with a discharge pipe, and an electrically controlled three-way valve is provided near the output end of the discharge pipe. A return pipe is connected to the electrically controlled three-way valve and is connected to the side wall of the mixing tank.

[0009] In a preferred embodiment, a return pump is provided on the return pipe.

[0010] In a preferred embodiment, the side wall of the mixing tank is provided with multiple liquid output pipes at different heights.

[0011] In a preferred embodiment, the bottom of the motor mounting base is provided with a shaft stabilizing housing, through which the shaft passes. Multiple positioning rings are fixed inside the shaft stabilizing housing, and the shaft passes through these positioning rings.

[0012] In a preferred embodiment, an ultrasonic vibrating rod is inserted through the bottom of the mixing tank.

[0013] The pharmaceutical stirring device for phosphogypsum treatment provided by this utility model has the following beneficial effects by adopting the above-described structure: (1) By setting up the phosphogypsum slurry receiving chamber and the flotation collector receiving chamber independently, and by periodically coinciding the distribution strip holes and the material passage holes on the rotating plate, the two materials can be precisely and quantitatively mixed, avoiding the problem of uneven local concentration caused by one-time feeding in the traditional mixing method. Moreover, the rotation of the rotating plate causes the phosphogypsum slurry and the flotation collector to form a cross-mixing flow during the falling process, which significantly improves the initial contact area and provides a good foundation for subsequent stirring. (2) Through the circulation loop consisting of an electrically controlled three-way valve and a return pump, the unmixed material can be transported back to the top of the mixing tank for secondary mixing to ensure the uniformity of mixing; (3) The shaft stabilizing housing and positioning ring at the bottom of the motor mounting base effectively reduce the radial wobble of the shaft, extend the service life of the bearing, and reduce the equipment failure rate; (4) The ultrasonic vibrating rod can break down the agglomerated parts in the phosphogypsum slurry, promoting full contact between the agent and the material.
