Description

Technical Field

[0001] This invention relates to the field of composite insulation material manufacturing technology for power equipment, and in particular to an insulator raw material pretreatment device. Background Technology

[0002] In the production of composite insulation materials such as power insulators, short fibers, serving as the reinforcing phase, and powdered raw materials, serving as the matrix, need to be uniformly mixed and pretreated to form a high-performance composite substrate. This process is similar to the uniform mixing of sand and cement in concrete production; the uniformity of this mixing directly determines the mechanical and insulation properties of the final product. Therefore, developing efficient pretreatment equipment is a key step in achieving large-scale production of high-quality insulators.

[0003] Currently, common technical solutions for achieving the above-mentioned mixing pretreatment are mainly divided into two categories. One category uses single-function equipment, such as relying solely on mechanical stirring paddles for mixing or solely on high-speed airflow for dispersion. The other category involves a simple sequential combination of equipment with different functions, such as first processing the fibers through an airflow dispersion device, and then feeding the dispersed fibers and powder together into a mechanical mixer for mixing, with each device operating independently.

[0004] However, whether it's a single-function device or a multi-step combination solution, there's a lack of effective coordination and linkage control between the processing stages. This results in the inability to dynamically match the flow rate, state, and processing intensity of materials at different stages, easily leading to problems such as material accumulation, secondary fiber agglomeration, or powder stratification. Ultimately, this restricts further improvement in mixing uniformity and makes it difficult to meet the production requirements of highly consistent products. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems in the prior art where the mechanical stirring and airflow dispersion processes lack coordination and cannot dynamically match the material state, resulting in uneven mixing, fiber agglomeration, and material accumulation.

The adjustment commands are used to increase the stirring power of the mechanical stirring mechanism 2 and / or increase the injection airflow intensity of the airflow dispersion mechanism 3.

[0009] Preferably, the mechanical stirring mechanism 2 includes a drive motor 21 and one or more stirring paddles 22 driven by the drive motor 21; The airflow dispersion mechanism 3 includes an air supply component 31 and a plurality of airflow nozzles 32 connected thereto. The plurality of airflow nozzles 32 are arranged circumferentially along the trajectory of the stirring paddle 22. The plurality of airflow nozzles 32 are connected to the air supply component 31 through a pipe rack 34 with multiple branches. The control unit 5 is configured to synchronously adjust the rotational speed of the drive motor 21 and the injection pressure or pulse frequency of the airflow nozzle 32 according to the status information.

[0010] Preferably, the main body of the stirring paddle 22 is a hollow cavity structure 221, and the surface of its blade 23 is distributed with a plurality of micropores 222 that communicate with the hollow cavity structure 221. The airflow dispersion mechanism 3 is connected to the hollow cavity structure 221 of the agitator 22 through the flow channel 33 in the tube frame 34, so that at least a portion of the dispersion airflow can be ejected into the material through the hollow cavity structure 221 and the micropores 222.

[0011] Preferably, the distribution density of micropores 222 on the surface of the blades 23 of the stirring paddle 22 increases from the root of the blades 23 to the tip of the blades 23, and the air outlet direction of the micropores 222 is inclined at an acute angle relative to the surface of the blades 23 to conform to the material flow direction during stirring.

[0012] Preferably, the pipe support 34 is supported and fixed on the frame of the device by a support 341. The bottom of the pipe support 34 is provided with a thread, and a threaded sleeve 342 is screwed onto the outside of the thread. The threaded sleeve 342 and the support 341 are locked together by bolts.

[0013] Preferably, the integrated processing chamber 1 includes, in sequence along the material flow direction, a pre-dispersion zone 131, a main mixing zone 132, and a homogenization zone 133; The main airflow injection point of the airflow dispersion mechanism 3 is located in the pre-dispersion zone 131; The core mixing component of the mechanical mixing mechanism 2 is located in the main mixing zone 132; At least one detection point of the monitoring unit 4 is located downstream of the main mixing zone 132 and / or the homogenization zone 133.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention constructs a closed-loop control system that integrates monitoring and control units to achieve perception, decision-making, and execution. The system can acquire the material mixing state online in real time and dynamically and synchronously adjust the parameters of mechanical stirring and airflow dispersion accordingly. This intelligent collaborative mechanism completely changes the traditional working mode of isolated or simply superimposed functions of equipment, ensuring that the material state and processing intensity are always optimally matched. It solves problems such as material accumulation, secondary fiber agglomeration, and powder stratification, achieving high-precision, adaptive control of the mixing uniformity of short fibers and powder raw materials.

[0017] When agglomeration is detected, the system precisely enhances the shearing and dispersion in specific areas, avoiding a crude intensification of the entire cavity that could lead to excessive energy consumption or dust generation. Simultaneously, the pre-dispersion zone, designed with a Venturi tube structure, efficiently disperses the fibers at the inlet, reducing the load on the main mixing zone and thus improving the overall efficiency and energy efficiency ratio of the pretreatment process.

[0018] By designing the agitator paddle as a hollow structure with directional micropores, the dispersing airflow can be directly ejected from within the agitation shear surface. This innovative structure deeply integrates airflow dispersion and mechanical agitation at both spatial and operational levels, achieving precise operation of simultaneous shearing and penetration dispersion, which is particularly effective in breaking down stubborn fiber clusters. Combined with the circumferential arrangement of the airflow nozzles, a three-dimensional, multi-scale synergistic dispersion network is formed, significantly enhancing the ability to break down fiber agglomerates.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] Please see Figure 1 - Figure 9An insulator raw material pretreatment device is disclosed, the core of which lies in the construction of an integrated and intelligent mixing pretreatment system. It mainly includes an integrated processing chamber 1, a mechanical stirring mechanism 2, an airflow dispersion mechanism 3, a monitoring unit 4, and a control unit 5. Through real-time sensing of the mixing process by the monitoring unit 4, and coordinated control of the mechanical stirring and airflow dispersion by the control unit 5, high-precision and adaptive regulation of the mixing uniformity of short fibers and powder raw materials is achieved, fundamentally solving the problems of material accumulation, secondary fiber agglomeration, and powder stratification mentioned in the background technology.

[0028] The integrated processing chamber 1 is the main structure of the entire device, providing a sealed and controllable space for material pretreatment. It has a raw material inlet 11 at the top for feeding short fibers and powder raw materials, and a mixed material outlet 12 at the bottom or lower side. Internally, it forms a processing channel 13 connecting the inlet and outlet. To optimize the process flow, this processing channel 13 is physically or logically divided into three functional areas along the material flow direction: The pre-dispersion zone 131 is located near the raw material inlet 11. Its main function is to use high-speed airflow to initially disperse the newly entered, easily agglomerated fibers. The main airflow injection point of the airflow dispersion mechanism 3 is located in the pre-dispersion zone 131.

[0029] The main mixing zone 132 is located downstream of the pre-dispersion zone 131 and is the core area where mechanical stirring and airflow dispersion work together, where the main mixing of fibers and powders is completed.

[0030] The homogenization zone 133 is located downstream of the main mixing zone 132 and upstream of the mixed material outlet 12. It is used to perform gentle and thorough final homogenization of the initially mixed materials to eliminate microscopic non-uniformity. At least one detection point of the monitoring unit 4 is set downstream of the main mixing zone 132 and / or the homogenization zone 133.

[0031] Preferably, as shown in the appendix Figure 3 As shown, the cavity wall of the pre-dispersion zone 131 is constructed as a tapered Venturi tube structure 1311, with the throat 1312 having the smallest cross-sectional area. This structure can utilize the Venturi effect to generate a high-speed, low-pressure zone in the throat 1312, greatly improving the tearing and dispersion efficiency of the airflow on the fibers, while also helping to entrain powder and promote initial mixing.

[0032] The mechanical stirring mechanism 2 is the core component providing the mechanical shearing force. It includes a drive motor 21 and one or more stirring paddles 22 driven by the motor. The stirring paddles 22 extend into the main mixing zone 132 of the integrated processing chamber 1. In a preferred embodiment, as shown in the attached... Figure 2 and Figure 3As shown, the main body of the stirring paddle 22 is a hollow cavity structure 221, and its blades 23 have a large number of micropores 222 communicating with the hollow cavity. The distribution density of these micropores 222 is designed to increase from the root to the tip of the blade 23 to meet the needs of higher linear velocity and stronger diffusion assistance at the tip of the blade 23. At the same time, the axial direction of the micropores 222 is not perpendicular to the surface of the blade 23, but is inclined at an acute angle. The inclination direction is configured to follow the mainstream direction of the material during stirring. For example, on the pushing side of the blade 23, the airflow of the micropores 222 is inclined backward; on the back side, it is inclined forward to reduce the interference of the airflow on the mainstream field and achieve co-current mixing.

[0033] The airflow dispersion mechanism 3 is responsible for providing the dispersion airflow. It includes an air supply assembly 31, such as an air compressor, blower, and corresponding pressure stabilization and filtration devices, as well as multiple airflow nozzles 32 connected to the air supply assembly 31 via pipelines. Some of these airflow nozzles 32 are arranged around the cavity wall of the main mixing zone 132, aligned with the stirring trajectory of the agitator 22; another part of the airflow is introduced into the hollow cavity structure 221 of the hollow agitator 22 through the rotary joint 36 and the flow channel 33, and finally ejected from the micropores 222. The airflow dispersion mechanism 3 is connected to the hollow cavity structure 221 of the agitator 22 through the flow channel 33 in the tube frame 34, so that at least a portion of the dispersion airflow can be ejected into the material through the hollow cavity structure 221 and the micropores 222. This design allows the airflow to act directly on the shear plane generated by stirring and the material retention area, resulting in a more direct and efficient dispersion effect. In addition, at least one high-speed airflow nozzle 32 is disposed at the venturi throat 1312 of the pre-dispersion zone 131 or upstream thereof to achieve the best pre-dispersion effect.

[0034] The tube support 34 is fixed to the frame of the device by a support 341. To allow for fine-tuning of the installation height or angle to ensure precise alignment with the rotary joint 36, the bottom of the tube support 34 is threaded, and a threaded sleeve 342 is screwed onto the outside of this thread. After adjustment, the threaded sleeve 342 is locked to the support 341 by bolts, thereby stabilizing the entire airflow passage.

[0035] To supply air to the rotating hollow agitator 22, the output shaft of the drive motor 21 is connected to the rotating spindle of a rotary joint 36 via a coupling 35. The stationary outer shell of the rotary joint 36 is connected to the pipe rack 34 and communicates with the flow channel 33. The rotary joint 36 is a standard sealing component in the art for transferring fluid between a stationary pipeline and a rotating shaft. Depending on the specific application, a transfer pipeline 37 or an air pipe may be used to connect to the flow channel 33.

[0036] The monitoring unit 4 is used to acquire status information that directly or indirectly reflects the mixing uniformity online and in real time. The monitoring unit 4 includes an image acquisition device 41 (not shown in detail in the figure), whose industrial camera lens, through an observation window and equipped with a dustproof air curtain or cleaning device, is aimed at the main material movement area within the integrated processing chamber 1, such as the main mixing zone 132, to continuously acquire material image information including the fiber dispersion state. In addition, the monitoring unit 4 also includes sensors 42, which use acoustic emission sensors or pressure fluctuation sensors as auxiliary sensors. These sensors are directly attached to specific locations on the outer wall of the integrated processing chamber 1, such as the main mixing zone 132. They are used to capture characteristic acoustic signals or pressure fluctuation signals generated by the collision and friction between material particles and the chamber wall, and between particles, during the mixing process. The changes in the spectrum and amplitude of this signal are closely related to the flow state and uniformity of the material, and this signal will be input to the control unit 5 as part of the status information.

[0037] Control unit 5 is typically composed of an industrial computer or a high-performance PLC, not shown in the diagram. It is connected to the signals of all the aforementioned mechanisms via data cables. Its internal logic function modules include: The image analysis module 51 processes the material image information acquired by the image acquisition device 41, and uses machine vision algorithms to identify the characteristic parameters of fiber clusters, including at least cluster size and distribution density. The control output module 52 receives the characteristic parameter data from the image analysis module 51 and the acoustic / pressure signals from the sensor 42. The control unit 5 is configured to dynamically generate control commands based on the status information acquired by the monitoring unit 4, including image analysis results and sensor 42 signals. It compares, analyzes, and fuses real-time data with preset process thresholds. Based on the judgment result, the control output module 52 dynamically generates and issues linkage control commands. Specifically, when the identified characteristic parameters, such as cluster size, exceed the preset threshold, the control output module 52 generates and outputs adjustment commands to increase the stirring power of the mechanical stirring mechanism 2 and / or increase the injection airflow intensity of the airflow dispersion mechanism 3. Furthermore, the control unit 5 is specifically configured to synchronously adjust the rotational speed of the drive motor 21 and the injection pressure or pulse frequency of the airflow nozzle 32 based on the status information. For example, when the fiber cluster size is detected to be out of standard, the command will synchronously and proportionally increase the speed of the drive motor 21 and the output pressure of the air supply component 31 or the pulse frequency of the specific airflow nozzle 32 according to the preset algorithm, so as to achieve enhanced synergy between mechanical shearing and pneumatic dispersion, rather than single adjustment.

[0038] Working principle During use, short fibers and powder raw materials are fed into the pre-dispersion zone 131 of the integrated processing chamber 1 in proportion from the raw material inlet 11. The device is started, and the control unit 5 operates according to a preset initial mixing program, which sets a suitable combination of initial stirring speed and airflow intensity for the current raw materials. A high-speed airflow nozzle 32, located at the throat 1312 of the venturi tube, ejects a strong airflow, forming a high-speed turbulent zone at the throat 1312. This forcefully tears and disperses the falling fiber bundles for the first time, and allows for initial contact with the injected powder, thus performing pre-dispersion.

[0039] The pre-dispersed material enters the main mixing zone 132. The agitator 22 rotates under drive, applying strong mechanical shear and convective mixing to the material. At the same time, the airflow nozzles 32 arranged around the material and the airflow ejected from the micropores 222 on the blades 23 of the agitator 22 continuously blow and permeate the material, especially the fiber agglomerates, into a dispersion.

[0040] The crucial coordinated control occurs at this moment. Monitoring unit 4, especially image acquisition device 41, continuously acquires the real-time status of the material in the main mixing zone 132. Image analysis module 51 continuously analyzes the images and calculates the real-time characteristic parameters of the fiber clusters. Once control unit 5 determines that the current mixing state has not reached the preset standard, such as when the cluster size is greater than the threshold or the acoustic signal spectrum shows that the material flowability has deteriorated, control output module 52 immediately generates a control command. This command synchronously and proportionally adjusts the speed of drive motor 21 and the output parameters of airflow dispersion mechanism 3. This linkage ensures that mechanical force and aerodynamic force are always dynamically matched, avoiding both local powder compaction caused by insufficient airflow due to excessive stirring and overall flow field turbulence caused by insufficient shear due to excessive airflow.

[0041] The materials that have reached the initial mixing requirements flow into the homogenization zone 133. In this zone, the stirring intensity is reduced, primarily through gentle agitation or slow stirring, combined with a weak airflow, to eliminate final non-uniformity. The monitoring unit 4, with its detection point at the end of the homogenization zone 133, can be a second image acquisition point or a sensor 42 to perform a final inspection of the mixing effect. Its feedback information can be used to confirm the completion of this batch's mixing or to fine-tune control parameters to optimize the next batch.

[0042] For complex mixing tasks, control unit 5 can execute a preset multi-stage mixing program. For example, the first stage uses an aggressive mode with high rotation speed and high airflow to quickly disperse the agglomerates; once a significant reduction in agglomerates is detected, it automatically switches to the second stage with a main mixing mode of medium rotation speed and medium airflow; the final stage enters a homogenization mode with low rotation speed and weak airflow. The switching between stages is automatically triggered by the monitored trend of changes in status information.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any variations or modifications may be made to the implementation of the present invention without departing from the stated principles.
