Description

Technical Field

[0001] This utility model relates to the field of material dispersion technology, specifically a dispersion device for material production and processing. Background Technology

[0002] As is well known, the dispersion of nanomaterials refers to the process of uniformly dispersing nanoscale materials in a specific medium (such as liquids, polymers, etc.). Its function is to enhance the hardness and wear resistance of coatings, thereby improving overall performance. With proper dispersion, nanomaterials can remain stably in the medium for extended periods, resisting aggregation and sedimentation, ensuring sustained effectiveness.

[0003] A search revealed a nanomaterial dispersion device in publication number CN209564898U, which disperses nanomaterials in a solvent or matrix material by driving a stirring rod to rotate at high speed. However, this method of dispersing nanomaterials by rotating the stirring rod has the following shortcomings:

[0004] 1. Low dispersion efficiency: During stirring, the interaction between nanoparticles and the medium is limited, making it difficult to quickly break up agglomerates. Especially for severely agglomerated nanomaterials, the required stirring time is long and the effect is poor, resulting in low production efficiency;

[0005] 2. Poor dispersion uniformity: Stirring makes it difficult to ensure uniform dispersion of nanomaterials throughout the system, potentially resulting in localized areas of excessively high or low concentrations. This can lead to inconsistent material properties and affect product quality. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a dispersion device for material production and processing, which more effectively disperses materials, improves the dispersion effect, and enhances the overall performance of the materials.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a dispersion device for material production and processing, comprising a head and a container for storing materials. The head is equipped with a drive motor, and the rotating end of the drive motor is mounted with a connecting shaft. An impeller is fixedly mounted on the connecting shaft, and a rotating cylinder is fixedly mounted on the connecting shaft. The rotating cylinder is a hollow cylinder with an opening at one end. A dispersion zone for dispersing materials is formed between the outer wall of the rotating cylinder and the inner wall of the container. Flow holes are provided on the cylinder wall. During operation, the impeller and the rotating cylinder rotate synchronously. The impeller rotates inside the rotating cylinder to generate pressure, causing the material to circulate inside and outside the rotating cylinder.

[0010] Furthermore, the impeller is disposed inside the rotating drum.

[0011] Furthermore, the top of the rotating drum is sealed, while the opening is located at the bottom of the rotating drum.

[0012] Furthermore, the bottom of the rotating drum is sealed, while the opening is located at the top of the rotating drum.

[0013] Furthermore, the connecting shaft and the drive motor are detachably connected.

[0014] Furthermore, the bottom of the drive motor is provided with a cover for sealing the opening on the container.

[0015] Furthermore, a support frame is provided at the bottom of the machine head, and a height-adjustable bracket is installed on the support frame. The bracket is attached to the installation container, and a base is provided at the bottom of the support frame.

[0016] Furthermore, a lead screw is rotatably mounted on the support frame, the lead screw and the bracket are connected by threads, and a screwing block for rotating the lead screw is provided on the lead screw.

[0017] Furthermore, it also includes a controller for controlling the drive motor, the controller comprising:

[0018] The time detection module is used to detect the rotation time and stop time of the drive motor, and to send a corresponding output signal when the set time value is reached;

[0019] The control unit sends a signal to the motor drive module to control the rotation or stop of the drive motor according to the input signal, and sends a power-off signal to the motor drive module when the drive motor rotates and stops cyclically for a set number of cycles.

[0020] The motor drive module drives the drive motor to rotate or stops the drive motor according to the signal from the control unit.

[0021] Furthermore, the flow holes on the rotating drum are arranged horizontally, inclined upwards from the outside to the inside, or inclined downwards from the outside to the inside.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the present invention provides a dispersion device for material production and processing, which has the following beneficial effects:

[0024] This material dispersing device, used in material production and processing, features an impeller and a rotating drum connected to a shaft. The drum's wall has flow holes. As the impeller rotates, the pressure generated inside the drum forces the material to flow at high speed through the flow holes, continuously impacting and breaking up agglomerates, thus achieving uniform material dispersion. The material circulates inside and outside the drum, ensuring continuous dispersion and maintaining a uniform distribution throughout the system. This timely dispersal of agglomerates reduces the occurrence of clustering.

[0025] As the drum rotates, the flow holes on it also rotate, further promoting material mixing and allowing the material to better integrate with other components. This not only improves the dispersion effect but also enhances the overall performance of the material.

[0026] Furthermore, the dispersion zone formed between the outer wall of the rotating drum and the inner wall of the container allows the material to rotate at high speed inside the container. Under the action of strong centrifugal force, the material flowing through the flow holes collides with the rotating material when it flows out of the through holes, which generates huge shear stress between the particles, thereby more effectively dispersing the material and improving the dispersion effect.

[0043] 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.

[0044] Please see Figure 1-5 This utility model discloses a dispersion device for material production and processing, comprising a head 1 and a container 5 for storing materials (hereinafter referred to as materials). A cover 11 is provided at the bottom of the drive motor 4 to seal the opening on the container 5. The drive motor 4 is mounted on the head 1, and a connecting shaft 6 extends downward from the rotating end of the drive motor 4. An impeller 9 is fixedly mounted on the connecting shaft 6. When the impeller 9 rotates, the pressure generated inside the rotating drum 7 (hereinafter referred to as the rotating drum 7) causes the material to flow at high speed through the flow holes 8 on the wall of the rotating drum 7. Figure 8As shown, when the impeller 9 rotates clockwise, it generates positive pressure, causing the material to flow in through the opening of the rotating drum 7 and discharge through the flow holes 8 on the wall of the rotating drum 7; Figure 9 As shown, when the impeller 9 rotates counterclockwise, it generates negative pressure, causing the material to flow in through the flow holes 8 on the wall of the rotating drum 7 and out through the opening of the rotating drum 7, thus achieving internal and external circulation of the material within the rotating drum 7. In the following description, for ease of description, it is illustrated that when the impeller 9 rotates clockwise, it generates positive pressure, causing the material to flow in through the opening of the rotating drum 7 and out through the flow holes 8 on the wall of the rotating drum 7. Those skilled in the art will understand that changing the rotation direction of the impeller 9 to maintain the same flow direction of the material, or setting the impeller 9 to generate positive pressure when rotating counterclockwise (simply by reversing the rotation direction of the impeller 9), causing the material to flow in through the opening of the rotating drum 7 and out through the flow holes 8 on the wall of the rotating drum 7, is also possible. When the impeller 9 rotates, the pressure generated inside the rotating drum 7 forces the material to flow at high speed through the flow holes 8 on the wall of the rotating drum 7, continuously impacting the agglomerates, effectively breaking them up, and achieving uniform dispersion of the material. Simultaneously, the flow holes 8 on the rotating drum 7 also rotate, further promoting the mixing of the material and allowing it to better integrate with other components.

[0045] In addition, such as Figure 6-7 As shown, a rotating drum 7 is also fixedly installed on the connecting shaft 6. An impeller 9 is located inside the rotating drum 7. When the drive motor 4 drives the connecting shaft 6 to rotate, the rotating drum 7, impeller 9, and connecting shaft 6 rotate synchronously. The rotating drum 7 is a hollow cylinder with an opening at one end. The specific arrangement of the rotating drum 7 is as follows: Figure 8-9 As shown, the top of the rotating drum 7 is sealed, and the opening is located at the bottom of the rotating drum 7. Alternatively, as... Figure 10 As shown, the bottom of the rotating drum 7 is sealed, and the opening is located at the top of the rotating drum 7. Typically, as... Figure 8-10 As shown, when the opening of the rotating drum 7 is at the bottom, the impeller 9 is also located at the bottom of the connecting shaft 6; when the opening of the rotating drum 7 is at the top, the impeller 9 is also located at the top of the connecting shaft 6. The impeller 9 can also be located in any position.

[0046] Because the rotating drum 7 has flow holes 8 on its wall and an opening at one end, the material can only enter (or exit) through the opening at one end of the rotating drum 7 and exit (or enter) through the flow holes 8 on the wall of the rotating drum 7. A dispersion zone 10 for dispersing the material is formed between the outer wall of the rotating drum 7 and the inner wall of the container 5. The material in the dispersion zone 10 rotates at high speed in the container 5. Under the action of strong centrifugal force, the material flowing through the flow holes 8 collides with the rotating material when it flows out of the through hole, and causes huge shear stress between the particles, thereby more effectively dispersing the material and improving the dispersion effect.

[0047] like Figure 11-13As shown, the flow holes 8 on the rotating drum 7 are arranged horizontally, inclined upwards from the outside to the inside, or inclined downwards from the outside to the inside. By setting the flow holes 8 in different directions, the flow direction of the material can be changed. Moreover, the shape of the flow holes 8 can be circular, elliptical, or rectangular, etc., and the flow holes 8 can be arranged in an array or staggered.

[0048] like Figure 14 As shown, the rotating end of the drive motor 4 is equipped with a drive shaft 18. The end of the drive shaft 18 has a mounting groove 19 for mounting a connecting shaft 6 and matching the connecting shaft 6. A set screw 20 is threaded onto the outer wall of the drive shaft 18. The screw-in end of the set screw 20 abuts against the outer wall of the connecting shaft 6. Loosening the set screw 20 allows the connecting shaft 6 to be detached from the drive shaft 18, while tightening the set screw 20 secures the connecting shaft 6. Other detachable connection methods can also be used. The drive shaft 18 and the connecting shaft 6 are positioned by a key and groove to ensure synchronous rotation.

[0049] Furthermore, a support frame 2 is provided at the bottom of the machine head 1, and a height-adjustable bracket 13 is installed on the support frame 2. The bracket 13 is used to install the container 5, and a base 3 is provided at the bottom of the support frame 2. A lead screw 16 is rotatably mounted on the support frame 2, and a connecting block 14 is provided on the bracket 13. The connecting block 14 and the lead screw 16 are connected by threads. A through slot 15 is provided on the support frame 2 for the connecting block 14 to pass through, and a turning block 17 is provided on the lead screw 16 for rotating the lead screw 16. Rotating the lead screw 16 can adjust the height of the bracket 13 and the container 5. The bracket 13 and the container 5 can also be raised and lowered by setting an electric telescopic rod or other lifting device.

[0050] In addition, such as Figure 15 As shown, it also includes a controller 12 for controlling the rotation of the drive motor 4. The controller 12 includes:

[0051] The time detection module 1201 is used to detect the rotation time and stop time of the drive motor 4, and to send a corresponding output signal when the set time value is reached;

[0052] The control unit 1202 sends a signal to the motor drive module 1203 to control the rotation or stop of the drive motor 4 according to the input signal, and sends a power-off signal to the motor drive module 1203 when the drive motor 4 rotates and stops cyclically to reach the set number of cycles.

[0053] The motor drive module 1203 drives the drive motor 4 to rotate or stops the drive motor 4 according to the signal from the control unit 1202.

[0054] In summary, this material processing dispersion device, when in use, activates the drive motor 4, which drives the connecting shaft 6, impeller 9, and rotating drum 7 to rotate synchronously. The impeller 9 rotates inside the rotating drum 7, generating pressure. The material to be processed and related materials enter (exit) the rotating drum 7 from the inlet. Under the pressure generated by the impeller 9, the material is discharged (enters) through the flow holes 8 on the wall of the rotating drum 7, thus dispersing the material. Furthermore, the material in the dispersion zone 10 rotates at high speed within the container 5. Under the action of strong centrifugal force, the material flowing through the flow holes 8 collides with the rotating material as it exits the through-holes, generating significant shear stress between particles, thereby more effectively dispersing the material and improving the dispersion effect.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
