[0018] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1 to 4 This application provides a superphosphate ore mixing device, including a mixing cylinder 1, an auxiliary component 2, a mixing component 3, a support leg 4, a controller 5, a duct 6, and a discharge butterfly valve 7. The mixing cylinder 1 has a cylindrical structure and is used to contain phosphate rock powder and acid solution for mixing reaction. The mixing component 3 is provided at the bottom of the mixing cylinder 1 for stirring and mixing the materials. The auxiliary component 2 is provided on the top wall of the mixing cylinder 1 for assisting in the addition of acid solution and cleaning the inner wall of the mixing cylinder 1. Auxiliary component 2 includes an acid feed cylinder 21, a discharge pipe 22, a first butterfly valve 23, a rotating rod 24, a connecting frame 25, a support 26, a first motor 27, a crossbar 28, and a hanging rod 29. The support 26 is a ring structure and is fixedly installed on the outer top of the mixing cylinder 1 by bolts. The rotating rod 24 is rotatably connected to the inner top of the support 26 by bearings. The rotating rod 24 is vertically arranged and located at the axis of the mixing cylinder 1. Multiple connecting frames 25 are fixedly installed on the outer side of the rotating rod 24 by welding. The connecting frames 25 are evenly distributed along the circumference of the rotating rod 24. The outer side of each connecting frame 25 is fixedly connected by bolts. An acid feed cylinder 21 is fixedly installed. The acid feed cylinder 21 has a cylindrical structure with an open top for easy addition of acid. The bottom of the acid feed cylinder 21 is conical. A discharge pipe 22 is fixedly installed at the bottom of the conical bottom of the acid feed cylinder 21 by welding. The discharge pipe 22 is connected to the inside of the acid feed cylinder 21 and is used to discharge the acid inside the acid feed cylinder 21. A first butterfly valve 23 is fixedly installed at the connection between the acid feed cylinder 21 and the discharge pipe 22 by a flange. The first butterfly valve 23 is used to control the opening and closing of the discharge pipe 22, thereby controlling the discharge volume and timing of the acid. The first motor 27 is fixedly installed on the top of the bracket 26 by bolts. The first motor 27 is a servo motor. Its output end passes through the inside of the bracket 26 through a coupling and is fixedly installed on the top of the rotating rod 24. The first motor 27 is electrically connected to the controller 5 through wires. The controller 5 can control the start, stop, speed and rotation direction of the first motor 27, thereby controlling the rotation state of the rotating rod 24. When the rotating rod 24 rotates, it drives the connecting frame 25 and the acid feed cylinder 21 to rotate together, so that the acid discharged from the discharge pipe 22 can be evenly distributed on the material in the mixing cylinder 1. Multiple crossbars 28 are fixedly installed on the outer side of the rotating rod 24 by welding. The crossbars 28 are evenly distributed along the circumference of the rotating rod 24, and the crossbars 28 and the acid feed cylinder 21 are alternately arranged in the axial direction of the rotating rod 24 to ensure that the acid discharged from the discharge pipe 22 will not drip onto the outer side of the crossbars 28. The length of the crossbars 28 is adapted to the radius of the mixing cylinder 1. A hanging rod 29 is fixedly installed on the outer side of the crossbars 28 by welding. The hanging rod 29 is set vertically and its outer side is attached to the inner wall of the mixing cylinder 1. When the rotating rod 24 rotates, the crossbars 28 drive the hanging rod 29 to rotate together. The hanging rod 29 can scrape off the material attached to the inner wall of the mixing cylinder 1 to prevent material accumulation. Four support legs 4 are fixedly installed at the bottom of the mixing cylinder 1 by welding. The support legs 4 are evenly distributed along the circumference of the mixing cylinder 1, which supports the entire device and ensures the stability of the device. The bottom of the support legs 4 is equipped with anti-slip pads to increase the friction with the ground and further improve the stability of the device.

[0020] Multiple arrangement pipes 6 are fixedly installed on the outer bottom of the mixing cylinder 1 by welding. The arrangement pipes 6 are evenly distributed along the circumference of the mixing cylinder 1. The arrangement pipes 6 are connected to the inside of the mixing cylinder 1 and are used to discharge the mixed material. A discharge butterfly valve 7 is fixedly installed at the connection between the arrangement pipes 6 and the mixing cylinder 1 by flange. The discharge butterfly valve 7 is used to control the opening and closing of the arrangement pipes 6, thereby controlling the discharge of the material. The mixing assembly 3 includes a second motor 31, a magnetic coupler 32, a stirring rod 33, and stirring blades 34. The magnetic coupler 32 is bolted to the center of the bottom of the mixing cylinder 1. The second motor 31, which is a geared motor, is located at the bottom of the magnetic coupler 32 and is bolted to the outside of the bottom of the mixing cylinder 1. The stirring rod 33 is located at the top of the magnetic coupler 32 and is vertically positioned. The output end of the second motor 31 is connected to the stirring rod 33 via the magnetic coupler 32. Using the magnetic coupler 32 for transmission enables contactless transmission, avoiding leakage problems that may occur with traditional mechanical seals and preventing acid leakage from damaging the second motor 31. Multiple stirring blades 34 are fixedly installed on the outer side of the stirring rod 33 by welding. The stirring blades 34 are evenly distributed along the axial direction of the stirring rod 33 and have a spiral structure. This structure design can increase the contact area with the material and improve the stirring efficiency. The second motor 31 is electrically connected to the controller 5 through wires. The controller 5 can control the start, stop and speed of the second motor 31, thereby controlling the stirring state of the stirring rod 33 and the stirring blades 34. The stirring rod 33 and the stirring blades 34 are both located below the crossbar 28, so that the stirring blades 34 can fully stir the material in the lower area of ​​the mixing drum 1. At the same time, in conjunction with the movement of the crossbar 28 and the hanging rod 29 driven by the rotating rod 24, the material in the mixing drum 1 is stirred in all directions. The controller 5 is fixedly installed on the outer middle of the mixing drum 1 by bolts. The controller 5 is a PLC controller, and its surface is equipped with operation buttons and a display screen. The operation buttons are used to input control commands, and the display screen is used to display the operating parameters of the device, such as the speed of the first motor 27 and the second motor 31, the running time, etc., so as to facilitate the operator to monitor and operate. Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0021] Working principle: First, phosphate rock powder is added into mixing cylinder 1 through the feed inlet at the top of mixing cylinder 1. Then, the controller 5 starts the first motor 27 and the second motor 31. The first motor 27 drives the rotating rod 24 to rotate, which in turn drives the acid feed cylinder 21, the crossbar 28, and the hanging rod 29 to rotate together, adding acid into the acid feed cylinder 21. The first butterfly valve 23 is opened, and the acid is discharged through the discharge pipe 22 under its own gravity. As the acid feed cylinder 21 rotates, the acid can be evenly distributed on the phosphate rock powder in mixing cylinder 1. At the same time, the second motor 31 drives the stirring rod 33 and the stirring blade 34 to rotate through the magnetic coupler 32, stirring and mixing the phosphate rock powder and acid in mixing cylinder 1. During the rotation, the hanging rod 29 scrapes off the material adhering to the inner wall of mixing cylinder 1 to prevent material accumulation. The crossbar 28 also plays an auxiliary stirring role during the rotation, improving the mixing efficiency. After the materials are mixed, the first motor 27 and the second motor 31 are shut off by the controller 5, and then the discharge butterfly valve 7 is opened. The mixed materials are discharged through the arrangement pipe 6 under their own gravity and enter the subsequent production process.
