Description

Technical Field

[0001] This invention relates to the field of equipment technology for preparing ferric phosphate solution, specifically to a high-efficiency mechanical-liquid dual-stirring device for mixing ferric phosphate solution. Background Technology

[0002] Ferric phosphate, also known as high-ferric phosphate or orthophosphate, has the molecular formula FePO4. It is a salt formed by the reaction of iron salt solution and sodium phosphate, in which the iron is in the valence of +3. Its main uses are in the manufacture of lithium iron phosphate battery materials, catalysts, ceramics, supercapacitors, and other related products. The preparation of ferric phosphate involves the mixing and reaction of various chemical raw materials. Among these, the uniformity of the ferric phosphate solution mixing directly affects the quality and performance of the final product.

[0003] Currently, in the preparation of ferric phosphate solution, solution mixing is often simply achieved using agitators, which has low mixing efficiency and requires a long mixing time to achieve a certain degree of uniformity. This not only increases production costs but may also affect product production efficiency and quality. Moreover, due to factors such as differences in raw material properties, inconsistent control of mixing conditions, and equipment limitations, existing solution mixing technologies often fail to guarantee the uniformity of the ferric phosphate solution, leading to an increase in impurity content in the product and affecting its purity and crystal morphology. Furthermore, in order to improve the mixing effect, it is often necessary to increase the stirring speed or extend the mixing time, resulting in increased energy consumption. Summary of the Invention

[0004] The present invention aims to provide a high-efficiency mechanical-hydraulic dual stirring device for mixing ferric phosphate solution. The device uses a stirring rod assembly to mechanically stir the solution in the mixing cylinder, and uses a liquid suction assembly to periodically draw in and discharge the solution, thereby achieving hydraulic stirring of the solution. The simultaneous action of mechanical and hydraulic stirring results in high mixing efficiency and good uniformity of the solution during the preparation of ferric phosphate solution, effectively controlling production costs and ensuring the quality and performance of the final product.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-efficiency mechanical-liquid dual-stirring device for mixing ferric phosphate solution includes a mixing cylinder. A cylinder cover is detachably connected to the inlet end of the upper side of the mixing cylinder. The upper side of the mixing cylinder is also connected to a feed inlet and an air outlet. The lower side of the mixing cylinder has a discharge outlet connected to a control valve that controls its opening and / or closing. A first housing and several support frames for supporting and fixing the dual-stirring device are connected to the outer side of the mixing cylinder. The first housing is connected to a liquid-collecting assembly, a motor, and a transmission belt assembly. The output shaft of the motor is coaxially and fixedly connected to any pulley of the transmission belt assembly to drive its movement. The transmission belt assembly has a pulley connected to a stirring rod assembly, which is rotatably located inside the mixing cylinder. The liquid-collecting assembly includes an eccentric wheel, a sleeve, and a piston rod assembly. The sleeve is fixedly connected to the first housing, and the end of the sleeve is connected to a first conduit. The free end of the first conduit is located inside the mixing cylinder. The piston of the piston rod assembly is slidably located inside the sleeve. A connecting rod is connected to the end of the piston rod assembly away from the piston. The eccentric wheel is fixedly connected to the output shaft of the motor. The eccentric wheel has a groove, and the connecting rod slidably abuts against the groove.

[0007] Furthermore, the pulleys of the eccentric wheel, stirring rod assembly, and transmission belt assembly are all coaxially and fixedly connected to the output shaft of the motor. As the stirring rod assembly rotates downward, the eccentricity at the connecting rod of the eccentric wheel gradually decreases, the piston rod assembly moves upward relative to the sleeve, and the liquid-collecting assembly draws the solution inward. Conversely, as the stirring rod assembly rotates upward, the eccentricity at the connecting rod of the eccentric wheel gradually increases, the piston rod assembly moves downward relative to the sleeve, and the liquid-collecting assembly pushes out the solution inside it.

[0008] Furthermore, a second housing is connected to the outer side of the mixing cylinder, and a liquid-collecting assembly is also connected to the inner side of the second housing. The two sets of liquid-collecting assemblies are arranged in a mirror-symmetrical manner with the central plane of the mixing cylinder as the reference plane, and the free ends of the first conduits of the two liquid-collecting assemblies are arranged opposite each other.

[0009] Furthermore, both the inner sides of the first and second housings are fixedly connected to sliding grooves, and the piston rod assemblies of both liquid-collecting components are fixedly connected to sliders, which are slidably disposed on the inner side of the sliding grooves.

[0010] Furthermore, springs are connected to the inner sides of both the first and second housings via connecting plates. The free ends of the two springs are respectively connected to the piston rod assemblies of the two liquid-collecting assemblies, and the springs are sleeved on the outside of the piston rod assemblies.

[0011] Furthermore, the mixing cylinder includes a cylindrical portion in the middle and frustum portions at the upper and lower ends. The feed inlet and air outlet are located at the frustum portion at the upper end of the mixing cylinder. The stirring rod assembly is located at the cylindrical portion in the middle of the mixing cylinder. The first conduit is located at the frustum portion at the lower end of the mixing cylinder.

[0012] Furthermore, the air outlet is connected to a three-way pipe, one end of which is connected to a pneumatic component, and the air outlet of the pneumatic component is connected to a second conduit, the air outlet of the second conduit being located inside the mixing cylinder; the other end of the three-way pipe is connected to a valve for controlling its opening and / or closing.

[0013] Furthermore, the transmission belt assembly includes pulleys connected by a transmission belt, and both pulleys are fixedly connected to a stirring rod assembly, with the second guide tube disposed between the two stirring rod assemblies.

[0014] Furthermore, the feed inlet is located between the cylinder cover and the first and second boxes, and the feed inlet includes a first feed inlet and a second feed inlet for adding different raw materials for mixing.

[0015] Furthermore, there are four support frames, which are evenly distributed around the mixing cylinder.

[0016] The principles and beneficial effects of the technical solution are as follows:

[0017] 1. This invention provides a high-efficiency mechanical-liquid dual-stirring device for mixing ferric phosphate solution. A detachable cylinder cover is connected to the upper side of the mixing cylinder. Removing the cylinder cover facilitates the addition of mixing materials, while covering it ensures a sealed environment during the ferric phosphate solution preparation process. The inlet facilitates the addition of materials during the ferric phosphate solution preparation process. The vent is used to discharge gas from the inside of the mixing cylinder, and the outlet is used to discharge the solution after the ferric phosphate solution preparation is completed. A support frame fixes and supports the entire dual-stirring device. A liquid-collecting assembly, a motor, and a transmission belt assembly are connected inside the first housing, and the output shaft of the motor is connected to the pulley of the transmission belt assembly and the liquid-collecting assembly. The eccentric wheel is fixedly connected, and the pulley is connected to the stirring rod assembly. The eccentric wheel is connected to the piston rod assembly via a connecting rod. The motor drives the pulley and eccentric wheel to rotate, causing the stirring rod assembly to rotate and mechanically stir the solution in the mixing cylinder. Simultaneously, the piston rod assembly moves up and down along the axial direction of its sleeve under the action of the connecting rod and the eccentric wheel. The sleeve has a free end connected to a first guide tube located inside the mixing cylinder. When the piston rod assembly moves upward, the solution in the mixing cylinder is drawn into the sleeve under atmospheric pressure. When the piston rod assembly moves downward, the solution in the mixing cylinder is pushed out of the sleeve and returned to the mixing cylinder. With the continuous operation of the motor, the periodic rotation of the stirring rod assembly mechanically stirs the solution in the mixing cylinder, while the suction assembly periodically draws in and discharges the solution, performing hydraulic stirring. The simultaneous action of these two components results in high mixing efficiency and good uniformity of the solution during the preparation of ferric phosphate solution, effectively controlling production costs and ensuring the quality and performance of the final product.

[0018] 2. The present invention provides a high-efficiency mechanical-hydraulic dual-stirring device for mixing ferric phosphate solution. By controlling the connection relationship between the eccentric wheel, stirring rod assembly, and pulley of the transmission belt assembly and the output shaft of the motor, as well as the initial state of the eccentric wheel and stirring rod assembly, the liquid-collecting component draws the solution inward during the downward rotation of the stirring rod assembly, and pushes the solution outward during the upward rotation of the stirring rod assembly. During the downward rotation of the stirring rod assembly, a downward pressure is applied to the solution inside the mixing cylinder, and at this time, the liquid-collecting component is in the state of collecting the solution. The solution-collecting process is effective and efficient under the atmospheric pressure between the piston rod assembly and the sleeve and the external pressure of the stirring rod assembly. Conversely, during the upward rotation of the stirring rod assembly, an upward lifting force is applied to the solution inside the mixing cylinder, and at this time, the liquid-collecting component is in the state of discharging the solution. The discharged solution achieves "resonance" under the action of the stirring rod assembly, resulting in good mixing effect and high efficiency of the solution inside the mixing cylinder.

[0019] 3. The present invention provides a high-efficiency mixing iron phosphate solution mechanical-liquid dual stirring device, wherein two boxes are connected to the outside of the mixing cylinder, and two sets of oppositely arranged suction components are connected to the inside of the two boxes. The free ends of the first conduits of the two suction components are opposite to each other. During the process of suctioning the solution, the solution inside the mixing cylinder moves towards each other, improving the cross-mixing effect between the solutions. During the process of the sleeve discharging the solution, the solution discharged from the two first conduits impacts each other, accelerating the mixing between the solutions.

[0020] 4. The present invention provides a high-efficiency mechanical-liquid dual-stirring device for mixing ferric phosphate solution. A sliding groove is connected inside the housing, and a slider is connected to the piston rod assembly. During the up-and-down movement of the piston rod assembly, the slider slides in the sliding groove. Both guide and limit the movement of the piston rod assembly, improving the stability of the movement process and ensuring the functionality of the entire suction assembly in absorbing and discharging the solution. A spring is connected inside the housing and sleeved on the piston rod assembly. The elastic deformation and self-restoring force of the spring absorb the impact force during the movement, making the operation of the entire device more stable and smooth.

[0021] 5. The present invention provides a high-efficiency mechanical-liquid dual-stirring device for mixing ferric phosphate solution. The inlet and outlet are located on the upper side of the mixing cylinder, facilitating material addition and gas discharge during the solution preparation process. The stirring rod assembly is located in the middle of the mixing cylinder, facilitating the installation and debugging of all components of the dual-stirring device. The first conduit is located on the lower side of the mixing cylinder, allowing for the extraction and discharge of precipitated substances in the solution that the stirring rod assembly cannot handle, reducing material precipitation and improving solution uniformity. The outlet is connected to a pneumatic assembly via a three-way pipe, which directs the gas generated during the ferric phosphate solution preparation process into the pneumatic assembly. The system allows for repeated use of gas, which is introduced into the mixing cylinder via a second conduit to achieve pneumatic stirring of the solution, thus improving energy utilization. The free end of the second conduit is positioned between two stirring rods connected by a transmission belt to fill any possible mixing "blind spots" within the mixing cylinder, further enhancing the mixing effect. Four support frames are evenly distributed around the mixing cylinder, ensuring stability and uniform stress distribution throughout the process of preparing ferric phosphate solution using this dual-stirring device, thus guaranteeing safety during the preparation process.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0030] like Figures 1 to 5 As shown, a high-efficiency mechanical-hydraulic dual-stirring device for mixing ferric phosphate solution includes a mixing cylinder 1, which comprises a cylindrical section in the middle and frustum sections at the upper and lower ends. The frustum section at the upper end of the mixing cylinder 1 is connected to an inlet and an outlet 8. The inlet includes a first inlet 6 and a second inlet 7, which are used to add different raw materials for mixing. The outlet 8 is connected to a three-way pipe, one end of which is connected to a pneumatic component 24. The outlet end of the pneumatic component 24 is connected to a second conduit 23, which is located inside the mixing cylinder 1. The other end of the three-way pipe is connected to a valve for controlling its opening and / or closing. The inlet end on the upper side of the mixing cylinder 1 is connected to a cylinder cover 2 by a thread, and the lower side of the mixing cylinder 1 is provided with an outlet 3, which is connected to a control valve 4 for controlling its opening and / or closing.

[0031] The mixing cylinder 1 is connected to a first housing 9, a second housing 11, and four support frames 5 that support and fix the double stirring device. The four support frames 5 are evenly distributed around the mixing cylinder 1. The pneumatic assembly 24 is fixedly connected to the inner side of the second housing 11. The first housing 9 is connected to a liquid-collecting assembly, a motor 10, and a transmission belt assembly 13. The liquid-collecting assembly includes an eccentric wheel 14, a sleeve 17, and a piston rod assembly 18. The transmission belt assembly 13 includes pulleys connected by a transmission belt. Both pulleys are fixedly connected to stirring rod assemblies 12, and both stirring rod assemblies 12 are rotatably located inside the cylindrical part in the middle of the mixing cylinder 1. The second guide tube 23 is located between the two stirring rod assemblies 12. The pulleys of the eccentric wheel 14, stirring rod assembly 12, and transmission belt assembly 13 are all fixedly connected to the output shaft of the motor 10. Sleeve 17 is fixedly connected to the first housing 9. The opening end of sleeve 17 is connected to the first conduit 22. The free end of the first conduit 22 is located inside the lower frustum of the mixing cylinder 1. The piston of piston rod assembly 18 is slidably located inside sleeve 17. The upper end of piston rod assembly 18 is connected to connecting rod 16. Eccentric wheel 14 is provided with groove 15. Connecting rod 16 slides against groove 15. During the downward rotation of stirring rod assembly 12, the eccentricity at the connection between eccentric wheel 14 and connecting rod 16 gradually decreases, piston rod assembly 18 moves upward relative to sleeve 17, and liquid suction assembly draws solution inward. Conversely, during the upward rotation of stirring rod assembly 12, the eccentricity at the connection between eccentric wheel 14 and connecting rod 16 gradually increases, piston rod assembly 18 moves downward relative to sleeve 17, and liquid suction assembly pushes out the solution inside.

[0032] The inner side of the second housing 11 is also connected to a liquid-collecting assembly. The two sets of liquid-collecting assemblies are arranged symmetrically in mirror image with the central plane of the mixing cylinder 1 as the reference plane. The free ends of the first conduits 22 of the two liquid-collecting assemblies are arranged opposite each other. In addition, the inner sides of the first housing 9 and the second housing 11 are both fixedly connected to a sliding groove 21. The piston rod assembly 18 of the two liquid-collecting assemblies is fixedly connected to a slider 19, and the slider 19 is slidably disposed inside the sliding groove 21. The inner sides of the first housing 9 and the second housing 11 are both connected to a spring 20 through a connecting plate. The free ends of the two springs 20 are respectively connected to the piston rod assembly 18 of the two liquid-collecting assemblies, and the springs 20 are sleeved on the outside of the piston rod assembly 18.

[0033] The specific implementation process is as follows:

[0034] When preparing ferric phosphate solution using this dual-stirring device, first fix the entire mixing cylinder 1 using the support frame 5, open the cylinder cover 2, add raw materials into the mixing cylinder 1 through the upper inlet end of the mixing cylinder 1, then close the cylinder cover 2, and start the motor 10 to mix the raw materials inside the mixing cylinder 1. During the mixing process, open the first feed port 6 or the second feed port 7 as needed to add additional raw materials, and open the valve of the control three-way pipe or the pneumatic component 24 as needed to discharge the gas in the mixing cylinder 1 or reuse it for pneumatic stirring of the solution. After the ferric phosphate solution is mixed, open the control valve 4 to discharge the mixed ferric phosphate solution from the discharge port 3.

[0035] In this system, the motor 10 drives the pulley and eccentric wheel 14 to rotate, causing the stirring rod assembly 12 to rotate and mechanically stir the solution inside the mixing cylinder 1. The piston rod assembly 18, under the action of the connecting rod 16 and the eccentric wheel 14, moves up and down along the axial direction of its sleeve 17. When the piston rod assembly 18 moves upward, the solution inside the mixing cylinder 1 is drawn into the sleeve 17; when the piston rod assembly 18 moves downward, the solution inside the mixing cylinder 1 is pushed out of the sleeve 17 and returned to the mixing cylinder 1. The continuous operation of the motor 10 and the periodic rotation of the stirring rod assembly 12 mechanically stir the solution inside the mixing cylinder 1, while the suction assembly periodically draws in and discharges the solution, thus hydraulically stirring the solution inside the mixing cylinder 1. The simultaneous action of these two components results in high mixing efficiency and good uniformity of the solution during the preparation of the ferric phosphate solution, effectively controlling production costs and ensuring the quality and performance of the final product.

[0036] By controlling the connection relationship between the pulleys of the eccentric wheel 14, the stirring rod assembly 12, and the transmission belt assembly 13 and the output shaft of the motor 10, as well as the initial state of the eccentric wheel 14 and the stirring rod assembly 12, the liquid-collecting component draws the solution inward during the downward rotation of the stirring rod assembly 12, and pushes the solution outward during the upward rotation of the stirring rod assembly 12. During the downward rotation of the stirring rod assembly 12, the stirring rod assembly 12 applies a downward pressure to the solution inside the mixing cylinder 1. At this time, the liquid-collecting component is in the state of collecting the solution. The process of collecting the solution is effective and efficient under the atmospheric pressure between the piston rod assembly 18 and the sleeve 17 and the external pressure of the stirring rod assembly 12. Conversely, during the upward rotation of the stirring rod assembly 12, it applies an upward lifting force to the solution inside the mixing cylinder 1. At this time, the liquid-collecting component is in the state of discharging the solution. The discharged solution achieves "resonance" under the action of the stirring rod assembly 12, resulting in a good mixing effect and high efficiency of the solution inside the mixing cylinder 1.

[0037] Two sets of oppositely arranged suction components are connected inside the first box 9 and the second box 11. The free ends of the first conduits 22 of the two suction components are opposite to each other. During the process of suctioning the solution, the solution inside the mixing cylinder 1 moves towards each other, which improves the cross-mixing effect between the solutions. During the process of the sleeve 17 discharging the solution, the solutions discharged from the two first conduits 22 impact each other, which accelerates the mixing between the solutions.

[0038] A sliding groove 21 is connected inside the first housing 9 and the second housing 11, and a slider 19 is connected to the piston rod assembly 18. During the up-and-down movement of the piston rod assembly 18, the slider 19 slides in the sliding groove 21. Both guide and limit the movement of the piston rod assembly 18, improving the stability of the movement process and ensuring the functionality of the entire suction assembly in suction and discharge of solution. A spring 20 is connected inside the first housing 9 and the second housing 11 and sleeved on the piston rod assembly 18. The elastic deformation and self-restoring force of the spring 20 absorb the impact force during the movement, making the operation of the entire device more stable and smooth.

[0039] The inlet and outlet 8 are located on the upper side of the mixing cylinder 1 to facilitate the addition of materials and the discharge of gas generated during the solution process. The stirring rod assembly 12 is located in the middle of the mixing cylinder 1 to facilitate the installation and debugging of the components of the entire dual stirring device. The first conduit 22 is located on the lower side of the mixing cylinder 1 to facilitate the absorption and discharge of substances that cannot be handled by the stirring rod assembly 12 in the solution, thereby reducing material precipitation and improving the uniformity of the solution. The outlet 8 is connected to the pneumatic assembly 24 through a three-way pipe. The pneumatic assembly 24 reuses the gas generated during the preparation of the ferric phosphate solution and introduces the gas into the mixing cylinder 1 through the second conduit 23 to achieve pneumatic stirring of the solution and improve the energy utilization rate. The free end of the second conduit 23 is located between the two stirring rod assemblies 12 connected by the transmission belt assembly 13 to "fill in the gaps" in the mixing cylinder 1, thereby further improving the mixing effect of the solution.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
