Description

Technical Field

[0001] This utility model relates to the technical field of polycarbonate composite material production equipment, specifically to a chemical-resistant and seawater-resistant polycarbonate composite material mixing device. Background Technology

[0002] Polycarbonate is a high-performance engineering plastic with characteristics such as high strength, high toughness, and good transparency, and it has a wide range of applications in many fields. With the rapid development of industries such as marine engineering, shipbuilding, and coastal infrastructure construction, the requirements for the chemical corrosion resistance and seawater corrosion resistance of materials are becoming increasingly stringent.

[0003] In the preparation of chemically and seawater-resistant polycarbonate composites, the mixing process is crucial. The uniformity of the raw material mixing and the accuracy of the proportions directly affect the final performance of the composite material. Traditional mixing devices mostly use containers and stirring structures with unidirectional stirring, which have dead zones, resulting in uneven material mixing and affecting the consistency of the composite material's performance.

[0004] In view of this, we propose a mixing device for chemically and seawater-resistant polycarbonate composite materials. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a mixing device for chemical-resistant and seawater-resistant polycarbonate composite materials.

[0006] The technical solution of this utility model is: A mixing device for chemically and seawater-resistant polycarbonate composite materials includes a spherical mixing tank. A mounting frame is rotatably installed inside the mixing tank. The inner wall of the mounting frame is equipped with crisscrossing horizontal and vertical stirring rods, all integrally formed with the mounting frame. A drive mechanism is mounted on the top and left side of the mounting frame. An insertion hole for the drive mechanism is located at the center of the top and left side of the mounting frame. Several metering funnels are installed near the top of the mixing tank. A discharge pipe communicating with the interior of the mixing tank is installed at the bottom of each metering funnel, and a metering valve is installed on the discharge pipe. This invention utilizes a spherical mixing tank to ensure thorough mixing without dead zones, improving mixing uniformity. The integral molding of the horizontal and vertical stirring rods with the mounting frame enhances structural strength, enabling it to withstand high-intensity mixing operations. The drive mechanisms on the top and left sides can switch drive directions via the insertion holes, achieving multi-dimensional rotation and mixing of the mounting frame. Combined with the metering funnels and the discharge pipe with metering valves, the input of each raw material can be precisely controlled, ensuring accurate composite material formulation ratios and improving mixing quality.

[0007] As a preferred technical solution, a support ring is fixedly installed on the outer wall of the mixing tank near the bottom, and several legs arranged in a circular array are fixedly installed at the bottom of the support ring. This provides a stable support foundation for the spherical mixing tank.

[0008] As a preferred technical solution, the drive mechanism includes a mounting plate located on the outside of the mixing tank, and two hydraulic cylinders symmetrically fixed to the top or left side of the mixing tank. The mounting plate is fixedly connected to the piston rods of the two hydraulic cylinders. A drive motor is mounted on the mounting plate, and a drive rod is coaxially fixed to the output shaft of the drive motor. A square rod is integrally formed coaxially at the end of the drive rod near the mixing tank. The square rod is inserted into a socket and its dimensions are adapted accordingly. The drive mechanism moves the mounting plate and drive motor via the hydraulic cylinders, causing the square rod on the drive rod to engage or disengage from the socket of the mounting frame, thus achieving switching and control of the drive of the mounting frame. The drive motor drives the mounting frame to rotate through the engagement of the square rod and the socket. The engagement structure of the square rod and the socket ensures the stability of power transmission.

[0009] As a preferred technical solution, the mixing tank has a circular hole for the square rod to pass through and rotate. This circular hole provides a channel for the square rod to pass through the mixing tank and engage with the mounting frame's insertion hole.

[0010] As a preferred technical solution, when the hydraulic cylinder piston rod is extended to its longest length, the square rod disengages from the insertion hole; when the hydraulic cylinder piston rod is retracted to its shortest length, the square rod engages with the insertion hole. By controlling the disengagement or engagement of the square rod with the insertion hole through the extension and retraction of the hydraulic cylinder piston rod, flexible switching of the power connection between the drive mechanism and the mounting frame is achieved. When it is necessary to change the rotation direction of the mounting frame, the square rod can be disengaged or inserted into the insertion hole by controlling the corresponding hydraulic cylinder. This operation is convenient and can quickly realize the drive conversion of the mounting frame in different directions, improving the operational flexibility and stirring efficiency of the device.

[0011] As a preferred technical solution, two limiting protrusions are symmetrically welded to the top and bottom of the mounting frame. The mixing tank has a transverse limiting groove for horizontal rotation and a longitudinal limiting groove for vertical rotation of the limiting protrusions around the center of the mounting frame. The limiting protrusions at the top and bottom of the mounting frame cooperate with the transverse and longitudinal limiting grooves inside the mixing tank to limit and guide the rotation of the mounting frame, ensuring that the mounting frame will not shift or fall off during horizontal and vertical rotation, thus guaranteeing the stability and accuracy of the mounting frame's rotation.

[0012] As a preferred technical solution, when the output shaft of the drive motor stops rotating, the two insertion holes are respectively aligned with the two square rods. This alignment facilitates accurate insertion of the square rods into the corresponding insertion holes by the hydraulic cylinder when the drive direction needs to be switched, eliminating the need for manual alignment adjustments, reducing operational steps, improving the efficiency and accuracy of drive direction switching, and ensuring the ease of operation of the device.

[0013] As a preferred technical solution, a sealing cap is threadedly installed at the bottom of the mixing tank. Two drive handles, symmetrically welded to the bottom of the sealing cap, are U-shaped. The threaded sealing cap reliably seals the bottom of the mixing tank, preventing material leakage during mixing. The U-shaped drive handles at the bottom of the sealing cap facilitate rotation by the operator, making installation and removal of the sealing cap easier and more convenient. This also facilitates material discharge after mixing and cleaning and maintenance of the mixing tank, enhancing the practicality of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a spherical mixing tank, which allows materials to be mixed without dead corners, improving mixing uniformity. The horizontal and vertical stirring rods inside the mounting frame are integrally formed with the mounting frame, enhancing structural strength and enabling it to withstand high-intensity stirring operations. The drive mechanisms on the top and left sides can switch drive directions through insertion holes, enabling multi-dimensional rotation and stirring of the mounting frame. Combined with a metering funnel and a discharge pipe with a metering valve, it can accurately control the input amount of each raw material, ensuring accurate formulation ratios of composite materials and improving mixing quality.

[0017] In a preferred embodiment, a support ring 3 is fixedly installed on the outer wall of the mixing tank 1 near the bottom, and several support legs 4 arranged in a circular array are fixedly installed at the bottom of the support ring 3. This provides a stable support foundation for the spherical mixing tank 1.

[0018] In a preferred embodiment, the drive mechanism includes a mounting plate 10 located on the outside of the mixing tank 1, and two hydraulic cylinders 11 symmetrically fixed to the top or left side of the mixing tank 1. The mounting plate 10 and the piston rods of the two hydraulic cylinders 11 are fixedly connected. A drive motor 12 is mounted on the mounting plate 10. A drive rod 13 is coaxially fixed to the output shaft of the drive motor 12. A square rod 14 is integrally formed coaxially at one end of the drive rod 13 near the mixing tank 1. The square rod 14 is inserted into the insertion hole 53 and is sized to fit the hole. The drive mechanism moves the mounting plate 10 and the drive motor 12 through the hydraulic cylinders 11, causing the square rod 14 on the drive rod 13 to be inserted into or separated from the insertion hole 53 of the mounting frame 5, thereby switching and controlling the drive of the mounting frame 5. The drive motor 12 drives the mounting frame 5 to rotate through the cooperation of the square rod 14 and the insertion hole 53. The insertion structure of the square rod 14 and the insertion hole 53 ensures the stability of power transmission.

[0019] In a preferred embodiment, the mixing tank 1 has a circular hole for the square rod 14 to pass through and rotate. The circular hole in the mixing tank 1 provides a channel for the square rod 14 to pass through the mixing tank 1 and engage with the insertion hole 53 of the mounting frame 5.

[0020] In a preferred embodiment, when the piston rod of the hydraulic cylinder 11 is extended to its longest length, the square rod 14 disengages from the insertion hole 53; when the piston rod of the hydraulic cylinder 11 is retracted to its shortest length, the square rod 14 engages with the insertion hole 53. By controlling the disengagement or engagement of the square rod 14 with the insertion hole 53 through the extension and retraction of the piston rod of the hydraulic cylinder 11, flexible switching of the power connection between the drive mechanism and the mounting frame 5 is achieved. When it is necessary to change the rotation direction of the mounting frame 5, the square rod 14 can be disengaged or inserted into the insertion hole 53 by controlling the corresponding hydraulic cylinder 11. The operation is convenient and can quickly realize the drive conversion of the mounting frame 5 in different directions, improving the operational flexibility and stirring efficiency of the device.

[0021] In a preferred embodiment, two limiting protrusions 52 are symmetrically welded to the top and bottom of the mounting frame 5. The mixing tank 1 has a transverse limiting groove 17 for horizontal rotation of the limiting protrusions 52 around the center of the mounting frame 5, and a longitudinal limiting groove 18 for vertical rotation. The limiting protrusions 52 at the top and bottom of the mounting frame 5 cooperate with the transverse limiting groove 17 and the longitudinal limiting groove 18 inside the mixing tank 1 to limit and guide the rotation of the mounting frame 5, ensuring that the mounting frame 5 will not shift or fall off when rotating horizontally and vertically, thus guaranteeing the stability and accuracy of the rotation of the mounting frame 5.

[0022] In a preferred embodiment, when the output shaft of the drive motor 12 stops rotating, the two insertion holes 53 are respectively aligned with the two square rods 14. This alignment facilitates the hydraulic cylinder 11's accurate insertion of the square rods 14 into the corresponding insertion holes 53 when the drive direction needs to be switched, eliminating the need for manual alignment adjustments, reducing operational steps, improving the efficiency and accuracy of drive direction switching, and ensuring the ease of operation of the device.

[0023] In a preferred embodiment, a sealing cover 15 is threadedly installed at the bottom of the mixing tank 1. Two drive handles 16, which are U-shaped, are symmetrically welded to the bottom of the sealing cover 15. The threaded sealing cover 15 reliably seals the bottom of the mixing tank 1, preventing material leakage during the mixing process. The U-shaped drive handles 16 at the bottom of the sealing cover 15 facilitate the operator's rotation of the sealing cover 15, making the installation and removal of the sealing cover 15 easier and more convenient. This also facilitates the discharge of materials after mixing and the cleaning and maintenance of the inside of the mixing tank 1, improving the practicality of the device.

[0024] In use, the chemical-resistant and seawater-resistant polycarbonate composite material mixing device of this invention first requires the operator to add the polycarbonate base material, chemical resistant agent, seawater-resistant additive, and other raw materials to the various metering funnels 2 at the top of the mixing tank 1 according to the formula requirements. By controlling the metering valve 21 on the feed pipe 20, the feed amount of each raw material is precisely controlled to ensure that the raw materials enter the spherical mixing tank 1 in a preset ratio.

[0025] After the raw materials are fed in, the drive mechanism is activated: the piston rod of the hydraulic cylinder 11 in the corresponding direction is controlled to retract, so that the square rod 14 at the end of the drive rod 13 is inserted into the corresponding insertion hole 53 in the mounting frame 5. At this time, the drive motor 12 starts, and through the cooperation of the square rod 14 and the insertion hole 53, it drives the mounting frame 5 to rotate. The horizontal stirring rods 51 and vertical stirring rods 50 crisscrossing on the inner ring wall of the mounting frame 5 rotate synchronously with the mounting frame 5, stirring and mixing the materials in the tank.

[0026] When it is necessary to change the stirring direction to improve mixing uniformity, the operation of the current drive motor 12 is stopped first. At this time, the two insertion holes 53 of the mounting frame 5 automatically align with the square rods 14 of the two drive mechanisms. Then, the piston rod of the hydraulic cylinder 11 in that direction is extended, causing the square rod 14 to disengage from the insertion hole 53. Then, the piston rod of the hydraulic cylinder 11 in the other direction is retracted, allowing the corresponding square rod 14 to insert into the other insertion hole 53. The drive motor 12 in that direction is then started, realizing the rotation and stirring of the mounting frame 5 in different dimensions. During this process, the limiting protrusions 52 at the top and bottom of the mounting frame 5 slide along the transverse or longitudinal limiting grooves 18 inside the mixing tank 1, ensuring the stable rotation of the mounting frame 5.

[0027] After mixing is complete, the drive motor 12 is turned off. The operator then removes the sealing cover 15 from the mixing tank 1 by rotating the U-shaped drive handle 16 on the bottom sealing cover 15, allowing the mixed composite material to be discharged from the tank. The entire process achieves efficient and uniform mixing of chemical-resistant and seawater-resistant polycarbonate composite materials through multi-dimensional stirring, precise metering, and stable support.
