Description

Technical Field

[0001] This utility model relates to the field of reactor technology, specifically a reactor for leaching phosphate rock. Background Technology

[0002] A phosphate rock leaching reactor is a device specifically designed for leaching phosphate rock. It is designed to improve leaching efficiency and reduce production costs. In the reactor, phosphate rock reacts with a specific solvent (such as sulfuric acid, nitric acid, or phosphoric acid) to produce phosphates and other products. During the reaction, the reactants need to be continuously stirred by a stirring device.

[0003] Traditional phosphate rock leaching reactors often employ a single structural design, such as a simple tank or stirred tank. Due to limitations in structural design, the mixing effect within the reactor is not ideal, and uniform mixing and stirring cannot be achieved. This results in a limited contact area between reactants and a reduced reaction rate. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a reactor for leaching phosphate rock, comprising a reactor body, a fixed frame fixedly mounted on the top of the reactor body, a servo motor fixedly mounted on the top of the fixed frame, a main pulley fixedly mounted on the bottom end of the transmission shaft of the servo motor, a rotating seat rotatably connected to the top center of the reactor body, a driven pulley fixedly mounted on the top of the rotating seat, a transmission belt sleeved on the outer side of the main pulley and the driven pulley, and a mixing component for uniform mixing and stirring arranged at the bottom of the rotating seat inside the reactor body.

[0005] As an optimization, the mixing assembly includes a housing fixedly installed at the bottom of the rotating seat and located inside the reactor body. An adjustable stirring plate is arrayed on the outer side of the housing. A bearing sleeve is rotatably connected to one side of the bottom slope of the housing. A stirring rod is rotatably connected inside the bearing sleeve. Two sets of stirring blades are fixedly installed at the bottom end of the stirring rod by bolts.

[0006] As an optimization, the adjustable stirring plate consists of a sleeve plate fixedly installed on the outside of the outer shell and a telescopic plate slidably inserted into the inside of the sleeve plate. The length of the adjustable stirring plate can be adjusted by pulling the telescopic plate in and out of the sleeve plate.

[0007] As an optimization, the angle between the stirring blade and the stirring rod can be adjusted by bolts, and a rotating blade is fixedly installed on the surface of the stirring blade.

[0008] As an optimization, a fixing rod is inserted into the center of the inner shell, and the top end of the fixing rod is fixedly installed on the bottom side of the fixing frame. A fixed bevel gear is fixedly installed at the bottom end of the fixing rod inside the shell, and a movable bevel gear is fixedly installed at the top end of the stirring rod inside the shell. The movable bevel gear and the fixed bevel gear are meshed together.

[0009] As an optimization, the vanes are blade-shaped, and the vanes on both sides are symmetrically arranged.

[0010] As an optimization, the movable bevel gears and stirring rods are arranged in three sets around the fixed bevel gear array, and the stirring rods are set at an angle of 60° relative to the fixed rods.

[0011] The beneficial effects of this utility model are:

[0012] The reactor used for leaching phosphate rock rotates so that the rotating shell drives the movable bevel gear to rotate around the fixed bevel gear. Since the fixed bevel gear is stationary, the movable bevel gear rotates on its own axis while rotating around the fixed bevel gear. This, in turn, drives the stirring blades and rotary vanes to rotate around the stirring rod as an axis. As a result, the stirring blades and rotary vanes revolve around the shell and rotate on their own axes around the stirring rod, thereby further improving the uniformity of mixing and stirring, making the contact between reactants more thorough, and improving the reaction efficiency.

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 A reactor for leaching phosphate rock includes a reactor body 1. A fixed frame 2 is fixedly installed on the top of the reactor body 1. A servo motor 3 is fixedly installed on the top of the fixed frame 2. A main pulley 4 is fixedly installed at the bottom end of the transmission shaft of the servo motor 3. A rotating seat 5 is rotatably connected to the top center of the reactor body 1. A driven pulley 6 is fixedly installed on the top of the rotating seat 5. A transmission belt 7 is sleeved on the outer side of the main pulley 4 and the driven pulley 6. A mixing component for uniform mixing and stirring is set at the bottom of the rotating seat 5 inside the reactor body 1. By starting the servo motor 3, the main pulley 4 will be driven to rotate, which in turn will drive the driven pulley 6 to rotate through the transmission belt 7. Therefore, the mixing component will be driven to rotate and stir inside the reactor body 1 through the rotating seat 5, thereby uniformly mixing the reactants inside the reactor and improving the reaction efficiency.

[0021] Please see Figure 2-3 The mixing assembly includes a housing 8 fixedly installed at the bottom of the rotating seat 5 and located inside the reactor body 1. Adjustable stirring plates 9 are arrayed on the outer side of the housing 8. Bearing sleeves 10 are rotatably connected to the bottom inclined side of the housing 8. Stirring rods 11 are rotatably connected inside the bearing sleeves 10. Two sets of stirring blades 12 are fixedly installed at the bottom end of the stirring rods 11 by bolts. The rotating seat 5 drives the housing 8 to rotate inside the reactor, which in turn drives the vertical adjustable stirring plates 9 and the stirring blades 12 at the bottom end of the inclined stirring rods 11 to rotate synchronously, thereby enabling uniform mixing of the reactants inside.

[0022] Please see Figure 2-3The adjustable stirring plate 9 consists of a sleeve plate fixedly installed on the outside of the outer shell 8 and a telescopic plate slidably inserted into the inside of the sleeve plate. By pulling the telescopic plate in and out of the sleeve plate, the length of the adjustable stirring plate 9 can be adjusted, thereby adjusting the stirring depth.

[0023] Please see Figure 2-3 The stirring plate 12 can be adjusted by bolts to make an angle with the stirring rod 11. The surface of the stirring plate 12 is fixedly mounted with a rotary blade 13. The rotary blade 13 is blade-shaped and the rotary blades 13 on both sides are symmetrically arranged. The rotary blade 13 further stirs the internal reactants, making the contact between the reactants more sufficient and improving the reaction efficiency.

[0024] Please see Figure 3-4 A fixed rod 14 is inserted into the center of the outer shell 8, and the top of the fixed rod 14 is fixedly installed on the bottom side of the fixed frame 2. A fixed bevel gear 15 is fixedly installed at the bottom of the fixed rod 14 inside the outer shell 8. A movable bevel gear 16 is fixedly installed at the top of the stirring rod 11 inside the outer shell 8, and the movable bevel gear 16 and the fixed bevel gear 15 are meshed together. The movable bevel gear 16 and the stirring rod 11 are arranged in three arrays around the fixed bevel gear 15, and the stirring rod 11 is set at a 60° angle relative to the fixed rod 14. When the outer shell 8 is rotated, the movable bevel gear 16 will rotate around the fixed bevel gear 15. Since the fixed bevel gear 15 is fixed, the movable bevel gear 16 will rotate on its own axis while rotating around the fixed bevel gear 15. This will drive the stirring blade 12 and the rotary blade 13 to rotate around the stirring rod 11 as the axis, so that the stirring blade 12 and the rotary blade 13 will rotate around the stirring rod 11 as the axis while revolving around the outer shell 8, thereby further improving the uniformity of mixing.

[0025] When in use, starting the servo motor 3 will drive the main pulley 4 to rotate, which in turn will drive the secondary pulley 6 to rotate through the transmission belt 7. Therefore, the rotating seat 5 will drive the outer shell 8 to rotate inside the reactor, which will drive the vertical adjustable stirring plate 9 and the stirring blade 12 at the bottom of the inclined stirring rod 11 to rotate synchronously, thereby enabling the internal reactants to be mixed and stirred evenly.

[0026] At the same time, the rotation of the outer casing 8 will drive the movable bevel gear 16 to rotate around the fixed bevel gear 15. Since the fixed bevel gear 15 is stationary, the movable bevel gear 16 will rotate on its own axis while rotating around the fixed bevel gear 15. This will drive the stirring blade 12 and the rotary blade 13 to rotate around the stirring rod 11 as the axis. Thus, the stirring blade 12 and the rotary blade 13 can rotate on their own axis around the stirring rod 11 while revolving around the outer casing 8, thereby further improving the uniformity of mixing.

[0027] In summary, the reactor for leaching phosphate rock, when the outer shell 8 rotates, causes the movable bevel gear 16 to rotate around the fixed bevel gear 15. Since the fixed bevel gear 15 is stationary, the movable bevel gear 16 rotates on its own axis while rotating around the fixed bevel gear 15. This, in turn, causes the stirring blades 12 and swivel blades 13 to rotate around the stirring rod 11 as an axis. Therefore, the stirring blades 12 and swivel blades 13 rotate on their own axes while revolving around the outer shell 8, thereby further improving the uniformity of mixing and stirring, making the contact between reactants more sufficient, and improving the reaction efficiency.
