Description

Technical Field

[0001] The utility model relates to the technical field of beneficiation reagent processing devices, in particular to a mixing device for preparing raw materials of phosphate ore beneficiation reagents. Background Art

[0002] With the rapid development of the economy, the demand for steel is increasing, and the beneficiation scale of iron ore is also increasing day by day. Most of the minerals in nature have very poor floatability. Flotation is widely used in mineral processing. By flexibly and effectively controlling the flotation process with flotation reagents, minerals can be successfully separated according to people's requirements, so that resources can be comprehensively utilized. Using flotation reagents is the most flexible, effective and convenient means to control the flotation behavior of minerals. There are many types of flotation reagents, including both organic compounds and inorganic compounds, both acids and bases and different salts, etc. There are many classification methods for flotation reagents. The most basic method is to classify according to the use of the reagents, usually divided into the following three categories: collectors, frothers and regulators; A variety of solutions need to be added during the preparation of flotation reagents. Traditional devices are difficult to ensure the uniform mixing of solutions and difficult to timely master the weight of solutions.

[0003] The existing Chinese patent with the publication number of CN212328054U discloses a preparation device for low-temperature flotation reagents for mines, including a base, side plates, a top plate and a mixing tank. One side of the top of the base is fixedly connected to the side plate. An installation groove is concavely provided on one side of the top of the side plate. An installation protrusion is provided on one side of the top plate. The installation protrusion of the top plate is installed inside the installation groove of the side plate and is connected by a number of fasteners between the installation protrusion and the side plate. A weighing scale is provided at the central position of the top of the base. The mixing tank is placed on the weighing scale. A cylinder is provided at the central position of the top of the top plate. The hydraulic telescopic rod connected to the cylinder penetrates through the top plate and extends vertically downward and is fixedly connected to the installation frame. A micro motor is provided inside the installation frame. The output shaft of the micro motor is rotationally connected to a rotating shaft. The bottom end of the rotating shaft is fixedly connected to a stirring blade.

[0004] In view of the above and related existing technologies, the inventor believes that the following defects often exist: when the device is stirring, since there is no shielding at the top of the mixing tank, the raw materials are easy to splash out and need to be improved; Therefore, a mixing device for preparing raw materials of phosphate ore beneficiation reagents is proposed for the above problems. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and solve the above-mentioned technical problems, the utility model proposes a mixing device for preparing raw materials of phosphate ore beneficiation reagents.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A mixing device for preparing raw materials of phosphate ore beneficiation agents according to the present utility model includes two groups of conveying devices.
