Description

Technical Field

[0001] This utility model relates to the field of materials science and engineering technology, and in particular to a reaction vessel for preparing ferroelectric materials. Background Technology

[0002] The reactor for preparing ferroelectric materials is a key piece of equipment used in the synthesis of ferroelectric materials. Its body is typically made of corrosion-resistant metals such as stainless steel and titanium alloys, capable of withstanding high temperatures, high pressures, and highly corrosive media. Various heating methods are available, such as jacketed steam, jacketed hot oil, and electric heating, allowing for precise control of the reaction temperature. An internal stirring device, driven by a motor, ensures thorough mixing of the reactants, enhances heat and mass transfer processes, and improves reaction uniformity and efficiency.

[0003] During operation, the reactor for preparing ferroelectric and piezoelectric materials is heated by methods such as jacketed steam or electric heating, with precise temperature control to the required reaction temperature. The stirring device, driven by a motor, ensures uniform mixing of the reactants, enhancing mass and heat transfer. Under a set pressure, the reactants undergo chemical synthesis or crystal growth reactions. By controlling parameters such as temperature and stirring rate, the material's crystal lattice is ordered, forming a functional phase with ferroelectric or piezoelectric properties, thus achieving material preparation.

[0004] In the existing technology, the sealing device of some ferroelectric piezoelectric material preparation reactors is fastened with bolts. During operation, uneven bolt tightening may occur, resulting in uneven pressure distribution on the sealing surface, which may lead to media leakage, reactant contamination, or material loss. At the same time, the difference in bolt force may cause local stress concentration in the reactor body components, leading to deformation or cracks. Therefore, a ferroelectric piezoelectric material preparation reactor is proposed to solve the above problems. Utility Model Content

During operation, uneven bolt tightening may occur, resulting in uneven pressure distribution on the sealing surface, leading to medium leakage, reactant contamination, or material loss. At the same time, the difference in bolt force can cause local stress concentration in the reactor body components, leading to deformation or cracks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ferroelectric electrostatic material preparation reactor includes a tank body. Two support blocks are fixedly connected to the outside of the tank body. An electric push rod is fixedly connected inside each of the two support blocks. A moving block is fixedly connected to the drive end of the electric push rod. A rotating shaft is rotatably connected inside the moving block. A pressure rod is fixedly connected to the outside of the rotating shaft. A top cover is installed at the bottom of the pressure rod. Rotating rods are rotatably connected to both the front and rear sides of the pressure rod. A fixed block is rotatably connected to the bottom of the rotating rod. A support plate is fixedly connected to the bottom of the fixed block. A sealing ring is fixedly connected to the top of the tank body. A disassembly assembly for easy disassembly of the stirring part is provided at the top of the top cover.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a support column, the bottom end of which is fixedly connected to the top of the top cover. A motor is fixedly connected to the top of the support column, and a support is fixedly connected to the drive end of the motor. An electric push rod II is fixedly connected inside the support, and a moving plate is fixedly connected to the drive end of the electric push rod II. Multiple connecting blocks I are fixedly connected to the outer side of the moving plate, and connecting rods are rotatably connected to the inner sides of the multiple connecting blocks I. A V-shaped rod is rotatably connected to the other end of the connecting rod, and a connecting block II is rotatably connected to the outer side of the V-shaped rod. A fixing plate is fixedly connected to the adjacent side of the connecting block II, and a stirring paddle is installed on the adjacent side of the V-shaped rod.

[0010] As a further description of the above technical solution:

[0011] The support plate is fixedly connected to the outside of the tank body on one side, and the top end of the sealing ring is in contact with the bottom end of the top cover.

[0012] As a further description of the above technical solution:

[0013] The drive end of the electric push rod is slidably connected inside the support block, and the opposite side of the rotating rod is in contact with the inner side of the support block.

[0014] As a further description of the above technical solution:

[0015] The front and rear sides of the rotating shaft are rotatably connected to the inner side of the moving block, and the adjacent side of the rotating rod is in contact with the outer side of the tank.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the operator puts the top cover on, he starts the electric push rod one to push the moving block up. The rotating shaft drives the pressure rod to rotate. Since the bottom end of the rotating rod is fixed on the fixed block, the pressure rod presses down with the connection point as the axis, so that the tank body and the top cover are pressed together to seal the ring, thereby achieving a seal and preventing leakage of strong acids, strong alkalis and organic solvents. This ensures the airtightness under high temperature and high pressure, maintains the stability of reaction parameters, and improves the yield of material synthesis.

[0024] 2. In this utility model, starting the electric push rod two drives the moving plate to move, and through the connecting rod, the V-shaped rod rotates around the axis. When the moving plate moves down, the V-shaped rod closes to fix the stirring paddle. When it moves up, the V-shaped rod opens to release the stirring paddle, which facilitates quick disassembly and assembly of the stirring paddle, shortens maintenance time, facilitates replacement of worn or adapted blades for different processes, and improves production efficiency.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a ferroelectric piezoelectric material preparation reactor, comprising a tank body 1. The tank body 1 is the core container of the entire reactor, used to contain the reactants for the preparation of ferroelectric piezoelectric materials, providing a relatively enclosed space with certain pressure and temperature conditions to ensure that the reaction can proceed smoothly and achieve the expected results. Two support blocks 2 are fixedly connected to the outside of the tank body 1. The support blocks 2 serve to support and fix the electric push rod 3, providing a stable installation position for the electric push rod 3 so that it can work normally and exert its pushing force.

[0033] Both support blocks 2 are internally fixedly connected to an electric push rod 3, which is a driving component. Its driving end is connected to a moving block 4. Through telescopic movement, the moving block 4 is moved up and down, thereby pressing and releasing the top cover 11. The driving end of the electric push rod 3 is fixedly connected to the moving block 4. The moving block 4 is rotatably connected to a rotating shaft 5 inside. The rotating shaft 5 provides a fulcrum for the rotation of the pressure rod 6. The front and rear sides of the rotating shaft 5 are rotatably connected to the inner side of the moving block 4, so that the pressure rod 6 can rotate around the rotating shaft 5, thereby changing the tilt angle and position of the pressure rod 6.

[0034] A pressure rod 6 is fixedly connected to the outer side of the rotating shaft 5. The pressure rod 6 is connected to the moving block 4 through the rotating shaft 5. Its main function is to transmit the power of the electric push rod 3 to the top cover 11, thereby achieving the pressing operation of the top cover 11. The top cover 11 is installed at the bottom end of the pressure rod 6. The top cover 11 works in conjunction with the tank body 1 and the sealing ring 10 to form a sealed environment inside the device. Rotating rods 7 are rotatably connected to both the front and rear sides of the pressure rod 6. The rotating rods 7 provide auxiliary support and restraint for the pressure rod 6. When the pressure rod 6 rotates with the moving block 4, the rotating rods 7 provide a fulcrum for the pressure rod 6, allowing it to rotate around the rotating rods 7.

[0035] A fixed block 8 is rotatably connected to the bottom end of the rotating rod 7. The fixed block 8 connects the rotating rod 7 and the support plate 9, so that the support plate 9 provides stable support for the rotating rod 7. The support plate 9 is fixedly connected to the bottom end of the fixed block 8, and the support plate 9 provides support for the fixed block 8. In this way, the fixed block 8 and the rotating rod 7 play an auxiliary supporting role in the movement of the pressure rod 6, thereby enhancing the structural stability of the entire device.

[0036] A sealing ring 10 is fixedly connected to the top of the tank body 1. When the top cover 11 is tightly fitted with the sealing ring 10, it can effectively prevent gas exchange between the inside and outside of the tank body 1, prevent gas leakage during the reaction process, and also prevent impurities in the outside air from entering the tank body 1, ensuring the purity of the reaction environment and ensuring the normal progress of the ferroelectric material preparation reaction. The top of the top cover 11 is provided with a disassembly component for easy disassembly of the stirring part.

[0037] Reference Figure 1 , Figure 2 , Figure 4 The disassembly assembly includes a support column 12, the bottom of which is fixedly connected to the top of the top cover 11. The support column 12 serves as the support base for the motor 13, securely mounting the motor 13 above the top cover 11 to prevent shaking or shifting during operation. The top of the support column 12 is fixedly connected to the motor 13, which is the power source for the stirring paddle 22 to perform its stirring function. When the drive end of the motor 13 rotates, it drives the fixedly connected support 14 to rotate, thereby transmitting power to subsequent components, causing the stirring paddle 22 to stir the materials inside the tank 1, promoting uniform mixing and reaction.

[0038] A support 14 is fixedly connected to the drive end of motor 13. After receiving the power transmitted by motor 13, support 14 serves as a mounting carrier for components such as electric push rod 15 and moving plate 16. It provides stable mounting space and structural support for these components, and under the drive of motor 13, it can rotate the entire disassembled assembly, causing the stirring paddle 22 to form a circular stirring path within the tank 1. Electric push rod 15 is fixedly connected inside support 14, providing linear extension and retraction power. By controlling the extension and retraction of the drive end of electric push rod 15, the connected moving plate 16 can be moved up and down.

[0039] The drive end of the electric push rod 15 is fixedly connected to a movable plate 16. Multiple connecting blocks 17 are fixedly connected to the outer side of the movable plate 16. Connecting rods 18 are rotatably connected to the inner sides of each connecting block 17. The connecting blocks 17 serve as the pivot connecting the movable plate 16 and the connecting rods 18. The rotatable connection between the inner side of each connecting block 17 and the connecting rod 18 allows the movable plate 16 to rotate via the connecting blocks 17 when it moves up and down, thus converting the linear motion of the movable plate 16 into the rotational motion of the connecting rod 18, providing power transmission for the movement of the V-shaped rod 19.

[0040] The other end of the connecting rod 18 is rotatably connected to a V-shaped rod 19. The V-shaped rod 19, through its rotatable connection with the connecting rod 18, can swing accordingly according to the movement trajectory of the connecting rod 18. A connecting block 20 is rotatably connected to the outer side of the V-shaped rod 19. The connecting block 20 serves to connect the V-shaped rod 19 and the fixing plate 21. The fixing plate 21 is fixedly connected to the adjacent side of the connecting block 20. The fixing plate 21 can provide stable support for the components connected thereto, ensuring the stability of the component operation.

[0041] A stirring paddle 22 is installed on the side adjacent to the V-shaped rod 19. The stirring paddle 22 is a component that directly stirs the material inside the tank 1. Driven by components such as the motor 13 and the support 14, the stirring paddle 22 rotates and stirs, ensuring thorough mixing of the material and accelerating the chemical reaction. When it is necessary to disassemble, maintain, or replace the stirring paddle 22, the clamping of the stirring paddle 22 can be released by the coordinated movement of components such as the electric push rod 15, the connecting rod 18, and the V-shaped rod 19, allowing the stirring paddle 22 to be removed from the disassembly assembly.

[0042] Reference Figures 2 to 4 The support plate 9 is fixedly connected to the outer side of the tank body 1 on one side, providing stable support for the connected components. The top end of the sealing ring 10 contacts the bottom end of the top cover 11. Through the coordinated action of the tank body 1 and the top cover 11, the sealing ring 10 seals the device, preventing leakage of liquid or gas inside the device. The drive end of the electric push rod 3 is slidably connected inside the support block 2, providing support for the movement of the electric push rod 3. The opposite side of the rotating rod 7 contacts the inner side of the support block 2. The front and rear sides of the rotating shaft 5 are rotatably connected to the inner side of the moving block 4, and the adjacent side of the rotating rod 7 contacts the outer side of the tank body 1.

[0043] The outer side of the fixing plate 21 is fixedly connected to the inside of the support 14. The fixing plate 21 provides a stable support structure for the connecting block 20 and the V-shaped rod 19. When the V-shaped rod 19 drives the stirring paddle 22, the fixing plate 21 can withstand the force transmitted by the V-shaped rod 19, ensuring that the connecting block 20 and the V-shaped rod 19 remain stable during movement. The top end of the stirring paddle 22 is in contact with the bottom end of the fixing plate 21. A rotating shaft is rotatably connected inside the connecting block 20. The outer side of the rotating shaft is fixedly connected to the inside of the V-shaped rod 19, and the rotating shaft provides a fulcrum for the movement of the V-shaped rod 19. The side of the V-shaped rod 19 close to the outer side of the fixing plate 21 is in contact with the outer side of the fixing plate 21, and the drive end of the electric push rod 15 is slidably connected inside the support 14.

[0044] Working principle: The operator puts the top cover 11 on and starts the electric push rod 3. The electric push rod 3 starts to move, which drives the moving block 4 to move upward. The moving block 4 transmits its own movement to the pressure rod 6 through the rotating shaft 5. Since the bottom end of the rotating rod 7, which is rotatably connected to the outside of the pressure rod 6, is rotatably connected to the fixed block 8, and the fixed block 8 is fixed, the movement of the moving block 4 drives the pressure rod 6 to rotate around the connection point with the rotating rod 7. When the moving block 4 moves upward, it causes the end of the pressure rod 6 near the top cover 11 to press downward, so that the tank body 1 and the top cover 11 press the sealing ring 10 together, completing the sealing of the equipment. This can effectively prevent the leakage of strong acids, strong alkalis, organic solvents and other media during the reaction process, avoid material pollution and environmental hazards, and at the same time ensure the airtightness of the reaction system under high temperature and high pressure, prevent gas from escaping or air from entering and interfering with the reaction process, ensure the stability of parameters such as temperature and pressure, and improve the consistency of material synthesis and yield.

[0045] When the electric push rod 215 is activated, it begins to move, driving the movable plate 16 fixedly connected to its drive end. The movement of the movable plate 16 causes the connecting block 17 to move the connecting rod 18. The connecting rod 18 transmits the motion to the V-shaped rod 19, causing the V-shaped rod 19 to rotate around the rotating shaft inside the connecting block 20. When the electric push rod 215 drives the movable plate 16 downward, the V-shaped rod 19 retracts inward to fix the agitator 22. When the electric push rod 215 drives the movable plate 16 upward, the V-shaped rod 19 opens outward, releasing the agitator 22. This allows for convenient disassembly of the agitator 22, shortening equipment maintenance and cleaning time. When the agitator 22 shows wear, corrosion, or needs to be replaced with different types of blades to adapt to multi-reaction processes, it can be quickly disassembled and assembled, avoiding production stoppages caused by traditional complex disassembly processes and improving production efficiency.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
