Description

Technical Field

[0001] This utility model relates to the field of polymer material processing technology, and in particular to a composite material mixing container that can eliminate static electricity. Background Technology

[0002] Before processing, polymer materials are usually in the form of particulate matrix. To improve their performance, powdered additives such as antioxidants, flame retardants, and color masterbatches are often added. Due to the significant differences in particle size, density, and flowability between particles and powders, during high-speed mixing, powders are prone to agglomerate due to the large amount of static electricity generated by friction. At the same time, they are affected by gravity and settle to the bottom of the container, making it difficult to fully contact the upper particles. Meanwhile, particles, due to their larger volume and strong flowability, are mostly distributed in the middle and upper layers, resulting in obvious stratification, which seriously affects the performance consistency and quality stability of the final product.

[0003] Existing mixing devices mostly adopt a single spiral or paddle stirring structure, and the stirring method is limited to axial pushing or local tumbling. They lack multi-stage dispersion and three-dimensional circulation design for powder mixing systems, making it difficult to break up powder agglomerates formed by electrostatic adsorption and unable to establish stable vertical convection. This results in polymer particles floating on the upper layer and fine powder settling and accumulating at the bottom, exacerbating stratification, causing uneven mixing and poor batch stability, making it difficult to meet the process requirements of uniform component distribution for high-performance composite materials.

[0004] Therefore, it is necessary to design a composite material mixing container that can eliminate static electricity in order to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing mixing devices, such as simple structure, simple stirring method, difficulty in dispersing electrostatic agglomerates and forming effective convection, easy to cause powder stratification, uneven mixing and poor batch stability, this utility model provides a composite material mixing container that can eliminate static electricity.

[0006] The technical solution is as follows: A composite material mixing container capable of eliminating static electricity includes a support frame, a container body, a lid, a feed inlet, a motor, a beater, a stirring screw, stirring rods, and a controller. The container body is mounted on the upper part of the support frame, and the lid is threadedly connected to the top of the container body. Feed inlets are provided on the left and right sides of the lid, and a motor is mounted on the top center of the lid. The output shaft of the motor passes downward through the lid and extends into the interior of the container body. Beaters are provided on the left and right sides of the upper part of the motor's output shaft, and a stirring screw is mounted in the center of the motor's output shaft. Multiple stirring rods are evenly mounted circumferentially on the lower part of the motor's output shaft. A controller is mounted on the front of the support frame, and the controller is electrically connected to the motor.

[0007] Optionally, the two clappers are located directly below the corresponding feed inlets.

[0008] Optionally, it also includes ultra-high molecular weight polyethylene, electromagnetic shielding composite material, and antistatic polymer composite material. The container body wall is composed of a three-layer composite structure: the outermost layer is ultra-high molecular weight polyethylene, the middle layer is electromagnetic shielding composite material, and the inner layer is antistatic polymer composite material.

[0009] Optionally, the outer periphery of the stirring rod matches the shape of the inner wall of the container body, and the stirring rod slides in contact with the inner wall of the antistatic polymer composite material.

[0010] Optionally, it also includes an anti-static observation plate, which is embedded in the front middle of the container body.

[0011] Optionally, it also includes a grounding rod and a docking block. The grounding rod is connected to the lower right side of the container body. One end of the grounding rod is connected to the electromagnetic shielding composite material, and the other end of the grounding rod extends outside the container body and is threadedly connected to the docking block.

[0012] The beneficial effects are: 1. This utility model uses a tamper to break up the powder during feeding to prevent agglomeration, and the stirring screw breaks up the material stratification to achieve up-and-down circulation. The stirring rod adheres to the inner wall to shear and tumble, eliminating mixing dead corners, effectively solving the problems of uneven mixing, stratification and powder agglomeration.

[0013] 2. This utility model adopts a three-layer structure of ultra-high molecular weight polyethylene, electromagnetic shielding composite material and antistatic polymer composite material for the container body, and forms an electrostatic discharge path by combining grounding rod and docking block, which effectively suppresses the accumulation of static electricity caused by material friction, realizes rapid static discharge, and improves the safety of the mixing process.

[0014] 3. This utility model features a stirring rod whose outer contour matches the shape of the inner wall of the container and slides in contact with the antistatic inner wall, reducing dead corners of material residue; combined with an antistatic observation plate, it ensures uniform mixing and facilitates real-time observation of the internal state without affecting the overall antistatic performance.

Detailed Implementation

[0021] Example: A composite material mixing container capable of eliminating static electricity, such as... Figure 1 , Figure 2 and Figure 4 As shown, the container includes a support frame 1, a container body, a lid 3, a feed inlet 31, a motor 4, a beater 41, a stirring screw 42, stirring rods 43, and a controller 6. The container body is mounted on the upper part of the support frame 1. The lid 3 is threadedly connected to the top of the container body. Feed inlets 31 are provided on the left and right sides of the lid 3. The motor 4 is mounted on the top center of the lid 3. The output shaft of the motor 4 passes downward through the lid 3 and extends into the interior of the container body. Beaters 41 are provided on the left and right sides of the upper part of the output shaft of the motor 4. The two beaters 41 are located directly below the corresponding feed inlets 31. The stirring screw 42 is mounted in the middle of the output shaft of the motor 4. Multiple stirring rods 43 are evenly mounted circumferentially on the lower part of the output shaft of the motor 4. The outer circumferential contour of the stirring rods 43 matches the shape of the inner wall of the container body. The controller 6 is mounted on the front of the support frame 1. The controller 6 is electrically connected to the motor 4.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes ultra-high molecular weight polyethylene 2, electromagnetic shielding composite material 21, antistatic polymer composite material 22, and antistatic observation plate 23. The container body's cylindrical wall is composed of a three-layer composite structure: the outermost layer is ultra-high molecular weight polyethylene 2, the middle layer is electromagnetic shielding composite material 21, and the inner layer is antistatic polymer composite material 22. The stirring rod 43 slides in contact with the inner wall of the antistatic polymer composite material 22. An antistatic observation plate 23 is embedded in the front middle part of the container body.

[0023] like Figure 2 and Figure 5 As shown, it also includes a grounding rod 5 and a docking block 51. The grounding rod 5 is connected to the lower right side of the container body. One end of the grounding rod 5 is connected to the electromagnetic shielding composite material 21, and the other end of the grounding rod 5 extends out of the container body and is threadedly connected to the docking block 51.

[0024] When this device is needed, firstly, the powder or granular material to be mixed is added into the container body through the feed inlets 31 set on the left and right sides of the cover 3. The container body is installed on the upper part of the support frame 1, and the overall structure is stable. The top of the container is connected to the cover 3 by threads to ensure sealing and prevent material splashing or dust overflow. Then, the operator starts the motor 4 through the controller 6. The controller 6 is electrically connected to the motor 4 and can adjust the speed of the motor 4 to meet the mixing requirements of different materials.

[0025] After the motor 4 starts, its output shaft drives all the stirring components to operate synchronously. The patters 41 set on the left and right sides of the upper part of the output shaft are located directly below the corresponding feed inlets 31. When the patters 41 rotate, they periodically pass below the feed inlets 31 to beat and disperse the incoming material, effectively preventing the material from accumulating and clumping below the feed inlets 31, and ensuring continuous and smooth feeding. The stirring screw 42 installed in the middle of the output shaft generates axial thrust when it rotates, causing the material to circulate up and down along the inner cavity of the container body to achieve longitudinal mixing. At the same time, multiple stirring rods 43 evenly installed circumferentially at the lower part of the output shaft rotate at high speed with the shaft to tumble and stir the material, enhancing the mixing effect.

[0026] Crucially, the outer contour of the stirring rod 43 matches the shape of the inner wall of the container body, ensuring that it maintains sliding contact with the inner wall during rotation. Since the inner wall of the container body is made of antistatic polymer composite material 22, which has excellent electrostatic dissipation properties, the movement of the stirring rod 43 against it can not only effectively scrape off the material adhering to the inner wall and reduce residual dead corners, but also prevent the accumulation of static electricity due to friction. At the same time, the container body cylinder wall adopts a three-layer composite structure: the outermost layer is ultra-high molecular weight polyethylene 2, which provides high strength, wear resistance and corrosion resistance mechanical protection; the middle layer is electromagnetic shielding composite material 21, which has good conductivity and can quickly conduct the static charge generated inside; the inner layer is antistatic polymer composite material 22, which has surface conductivity and can conduct the static charge generated by the friction of the material to the middle electromagnetic shielding composite material 21, and then conduct it out through the grounding rod 5.

[0027] To ensure safe discharge of static electricity, a grounding rod 5 is connected to the lower right side of the container body. One end of the grounding rod 5 is connected to the electromagnetic shielding composite material 21 in the middle to form a conductive path, and the other end extends out of the container body and is connected to a docking block 51 by a thread. In use, the external grounding wire is connected to the docking block 51, which can quickly conduct the static charge generated during the mixing process to the ground and completely eliminate the static electricity safety hazard. In addition, an anti-static observation plate 23 is embedded in the front middle of the container body, which makes it easy for operators to observe the mixing status of the internal materials in real time. The anti-static observation plate 23 also has anti-static function and does not affect the overall static electricity protection performance.
