Description

Technical Field

[0001] This utility model relates to the technical field of solid buoyancy material processing equipment, and in particular to a vacuum degassing test device for the production and processing of solid buoyancy materials. Background Technology

[0002] Solid buoyancy materials, as a key functional material, play an irreplaceable role in deep-sea exploration and marine resource development. Their preparation requires the uniform mixing of a resin matrix with lightweight fillers such as hollow glass microspheres. However, during the stirring and casting processes, a large amount of air is inevitably incorporated, forming micron- to millimeter-sized bubble defects. These bubbles form a cavity structure after the material solidifies, significantly reducing its mechanical strength and affecting its water pressure resistance and long-term stability.

[0003] While traditional vacuum degassing equipment can induce bubble expansion and collapse through a negative pressure environment, it has significant limitations when processing high-viscosity solid buoyancy materials. Firstly, static vacuum treatment struggles to completely eliminate bubbles within the material. Secondly, the lack of an effective vibration-assisted system prevents the material from self-leveling and filling after bubble collapse. Furthermore, existing equipment generally suffers from inconvenient operation, unstable sealing performance, and low vibration transmission efficiency, making it difficult to meet the stringent requirements of degassing processes in the industrial production of solid buoyancy materials.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In existing technologies, vacuum degassing equipment often employs a single degassing method, such as relying solely on vacuum negative pressure or mechanical vibration to remove bubbles. In traditional equipment, the vacuum environment and vibration system often operate independently, resulting in insufficient material flowability after bubble rupture, making it impossible to effectively fill voids. Furthermore, in the production process of solid buoyancy materials, the mixture of resin and glass microspheres forms a high-viscosity material, making it difficult for bubbles to be completely expelled. The cavities formed after curing directly affect the material's density and mechanical properties.

[0030] To address these issues, researchers discovered that while vacuum pressure alone can accelerate bubble expansion and bursting, the surface tension of the material still hinders the filling of the voids after bursting. While mechanical vibration can promote material flow, it cannot eliminate the internal pressure difference within the bubble. By analyzing the physical processes of bubble bursting and material flow, it was realized that a vacuum environment and vibrational energy must work synergistically within a confined space to achieve simultaneous bubble bursting and void filling.

[0031] Therefore, based on the above design concept, such as Figure 1 and Figure 2 As shown, this application proposes a vacuum degassing test device for the production and processing of solid buoyancy materials, which mainly includes a body 100, a cover 200, a vibration component 300 and a vacuum component 400. The cover 200 is detachably installed at the opening at the top of the body 100, and the vibration component 300 is provided at the bottom of its inner cavity, and the inner cavity is connected to the vacuum component 400.

[0032] The machine body 100 refers to a circular container structure that forms a closed degassing space. It can be made of stainless steel or pressure-resistant composite materials and is used to hold materials and provide a vacuum environment. The cover 200 is a sealing component that covers the opening of the machine body 100. It can be achieved using a flange connection with a sealing ring to ensure stable pressure during the degassing process. The vibration assembly 300 is a device that generates mechanical vibration. It can be an eccentric motor driving a vibration platform, transmitting vibrational energy through direct contact with the material. The vacuum assembly 400 is a system that establishes a negative pressure environment. It can be a combination of a vacuum pump and pressure-resistant piping to quickly expel gas from the closed cavity.

[0033] Specifically, when the material is placed on the surface of the vibrating component, the cover 200 and the body 100 form a sealed cavity. After the vacuum component 400 is activated, the air pressure inside the cavity decreases, causing the bubbles to expand and burst. At this time, the mechanical vibration generated by the vibrating component 300 causes the material to flow in a shear manner, quickly filling the gaps formed by the bursting bubbles. The vacuum environment reduces the internal pressure of the material, and the vibration energy overcomes the viscous resistance of the material. The synergistic effect of the two achieves the dual effect of bubble elimination and surface leveling.

[0034] Compared to existing technologies, traditional equipment uses separate modules for the vacuum system and vibration device, making energy coupling impossible within a confined space. This solution integrates the vibration component at the bottom of the sealed cavity, allowing vibration energy to act directly on the material. Simultaneously, the design connecting the vacuum component to the cavity ensures rapid establishment of a negative pressure environment, creating a spatiotemporal synchronization between vacuum and vibration.

[0035] Through the above technical solution, this application effectively solves the technical problem of residual bubbles in the degassing process of high-viscosity materials, realizes the simultaneous completion of bubble rupture and void filling, and significantly improves the density uniformity and mechanical property stability of solid buoyancy materials.

[0036] In some of these embodiments, such as Figure 1As shown, this application further proposes a horizontally arranged cleaning discharge pipe 101 installed on the lower side wall of the machine body 100. The inlet of the cleaning discharge pipe 101 is located close to the bottom of the inner cavity of the tank, and a manual valve 102 is installed at the outlet of the cleaning discharge pipe 101. The horizontally arranged cleaning discharge pipe 101 refers to a tubular structure extending laterally along the side wall of the machine body, which can be implemented using a stainless steel pipe with a smooth inner wall. The inlet end of the cleaning discharge pipe extends to near the lowest point of the tank bottom. The manual valve 102 is a mechanical valve installed at the outlet end of the cleaning discharge pipe, which can be a ball valve or a plug valve. The opening and closing of the pipe is controlled by rotating the handle, achieving the switching between sealing and drainage.

[0037] Specifically, the horizontal arrangement of the cleaning discharge pipe 101 ensures that the liquid flows naturally along the pipe under gravity without needing to overcome additional resistance during discharge. The inlet's location near the lowest point of the tank ensures complete collection of the liquid after defoaming or during cleaning, preventing residue. The manual valve 102 remains closed when not discharging to prevent leakage from the vacuum environment due to pipe connections to the outside; during discharge, the valve is opened manually by rotating it, allowing operators to precisely control the discharge speed and timing.

[0038] In addition, such as Figure 1 As shown, this application further proposes that the body 100 adopts a circular barrel structure with an open top, and brakeable wheels 103 are installed at the four corners of its bottom. The circular barrel structure refers to a circular container with an open top. The brakeable wheels 103 are conventionally known mobile support components with locking mechanisms, specifically implemented using a combination of omnidirectional wheels and a foot brake, forming a stable support surface through a four-point symmetrical layout.

[0039] In some of these embodiments, such as Figure 2 As shown, this application further proposes that a plurality of fasteners 201 for detachable sealing connection to the body 100 are provided at intervals around the perimeter of the cover 200, and a vacuum gauge 202 is mounted on them. The fasteners 201 are mechanical fixing components used to achieve a detachable connection between the cover 200 and the body 100. Specifically, they can be implemented using conventionally known quick-clamping fasteners or rotary locking fasteners. The spacing of the fasteners can evenly apply sealing pressure, avoiding sealing failure caused by localized stress concentration. The vacuum gauge 202 is an instrument used to monitor the internal vacuum pressure of the device in real time. Specifically, it can be implemented using conventionally known pointer-type vacuum gauges or digital vacuum gauges.

[0040] Specifically, fasteners 201 are arranged in a ring at intervals along the edge of the cover 200, and mechanically lock the sealing ring between the cover 200 and the body 100, forming a uniformly distributed sealing contact surface to effectively prevent vacuum leakage. The vacuum gauge 202 is fixed to the cover 200 via a threaded interface or flange connection, and its sensing end is connected to the inner cavity of the device to display internal pressure changes in real time. Operators can adjust the operating parameters of the vacuum assembly 400 based on the reading of the vacuum gauge 202 to ensure the degassing process is in the optimal vacuum environment.

[0041] Through the above technical solution, this application solves the problem of insufficient reliability of the sealing connection between the cover 200 and the body 100, ensuring a stable vacuum environment; at the same time, the vacuum gauge 202 enables real-time monitoring and precise control of the vacuum degree, avoiding the impact of pressure fluctuations on the degassing effect, and improving the controllability and repeatability of the test process.

[0042] In addition, such as Figure 1 and Figure 2 As shown, this application further proposes that an exhaust valve 203 and two symmetrically arranged handles 204 be provided on the outer periphery of the top of the cover 200, and a transparent observation window 205 be provided in the middle of the top. The exhaust valve 203 is a device for controlling the depressurization of the vacuum chamber, which can be implemented using conventionally known solenoid valves or manual valves. The pressure release rate is controlled by adjusting the valve opening, avoiding sudden internal pressure changes that could cause material splashing. The handles can be made of bent metal and fixed to the edge of the cover 200 by bolts or welding, ensuring even force distribution when the operator moves or opens the cover, reducing the risk of displacement. The transparent observation window 205 is a viewing window made of pressure-resistant transparent material, specifically tempered glass or polycarbonate sheet embedded in the middle of the cover, sealed with a sealing ring to allow direct observation of the material degassing state in a vacuum environment.

[0043] Specifically, the exhaust valve 203 is installed on the outer periphery of the cover 200, allowing operators to quickly complete the pressure relief operation without moving, thus preventing material structure damage due to sudden pressure drops. Two symmetrical handles 204 are fixed to the front and rear ends of the cover 200, respectively. During operation, the direction of force applied by both hands coincides with the center axis of gravity of the cover 200, effectively preventing the cover 200 from tilting or slipping. The transparent observation window 205 is centrally located, covering the central area of ​​the vibration platform 301, allowing direct observation of bubble bursting and material flow, facilitating adjustments to vacuum pump operating parameters or vibration frequency based on real-time conditions.

[0044] Through the above technical solution, this application solves the problems of uneven force on the machine cover 200 during vacuum degassing, low efficiency of pressure relief operation, and limited observation of material status. It achieves the technical effects of single-handed pressure relief operation, stable handling of the machine cover 200, and real-time monitoring of the degassing process through the transparent observation window 205.

[0045] In some of these embodiments, such as Figure 1 and Figure 3 As shown, this application further proposes a vibration assembly 300 including a vibration platform 301 and a vibration motor 302. The vibration platform 301 is an annular disc-shaped structure with an open top, and the vibration motor 302 is fixedly installed at the center of its bottom. The vibration motor 302 is electrically connected to the controller 500.

[0046] The vibration platform 301 is a structural component used to support solid buoyancy materials and transmit vibration. Specifically, it can be a ring-shaped frame formed by welding metal materials. The ring design ensures uniform distribution of centrifugal force during vibration, avoiding localized stress concentration that could lead to material breakage. The vibration motor 302 is the power source that drives the vibration platform 301 to generate mechanical vibration. It can be a variable frequency motor, where the vibration intensity is controlled by adjusting the input current frequency. Centering the motor ensures that the vibration source is coaxial with the platform's center of mass, reducing energy loss caused by vibration offset. The controller 500 is electrically connected to the external control unit via a cable. It can be configured with a conventionally known PID control module to monitor vibration parameters in real time and provide feedback adjustments to adapt to the degassing requirements of materials with different viscosities.

[0047] Specifically, the vibration platform 301, under vacuum conditions, evenly distributes centrifugal force through its annular support surface, causing the bubbles inside the material to break under uniform force. The vibration motor 302 is installed at the center of the bottom of the vibration platform 301, ensuring that the vibration waves diffuse symmetrically from the center outwards, eliminating amplitude differences caused by off-center loading. The controller 500 dynamically adjusts the vibration frequency and amplitude of the motor according to a preset program; for example, it uses a high-frequency, low-amplitude mode to break large bubbles in the initial stage of degassing, and switches to a low-frequency, high-amplitude mode to fill micropores in the later stage.

[0048] Through the above technical solutions, this application realizes uniform vibration degassing of solid buoyancy materials in a vacuum environment, avoiding internal structural damage caused by uneven vibration distribution; the central symmetric driving method improves the stability of vibration transmission and ensures maximum energy utilization in the degassing process; adjustable vibration parameters match the needs of different process stages, and the ring support structure takes into account both mold positioning and material spillage prevention, and the overall structure maintains reliable connection under long-term high-frequency vibration.

[0049] In addition, such as Figure 1 As shown, this application further proposes that the vibration assembly 300 also includes a vibration base plate 303 and a buffer spring 304. The vibration base plate 303 is fixedly installed at the bottom of the inner cavity of the machine body 100, and a number of vertically arranged buffer springs 304 are fixedly installed on its periphery, and the top of each buffer spring 304 is fixedly connected to the bottom of the outer periphery of the vibration platform 101.

[0050] The vibration base plate 303 is a plate-like structure rigidly connected to the bottom of the machine body 100, which can be achieved by welding or bolting, and serves to provide a stable mounting reference for the buffer springs 304. The buffer springs 304 are elastic support members distributed in a ring around the periphery of the vibration base plate, and can be implemented using helical springs or disc springs. They absorb vertical vibration impacts and limit lateral displacement through elastic deformation. Specifically, the vibration base plate 303 is rigidly fixed to the bottom of the machine body 100, forming the mounting base for the vibration assembly. Several buffer springs 304 are evenly distributed around the periphery of the vibration base plate 303, with their lower ends fixedly connected to the vibration base plate 303 and their upper ends fixedly connected to the outer bottom of the vibration platform 301.

[0051] When the vibration motor 302 drives the vibration platform 301 to generate high-frequency vibration, the buffer spring 304 absorbs the vertical impact component of the vibration energy through elastic deformation, preventing rigid impact from being transmitted to the machine structure. Simultaneously, the annularly distributed buffer springs 304 form multi-point constraints on the outer periphery of the vibration platform, limiting the horizontal offset of the vibration platform 301 and ensuring that the vibration energy is concentrated on the material in the vertical direction. The vibration base plate 303 serves as a rigid support foundation, maintaining the stability of the installation position of the buffer springs 304 and preventing the vibration platform 301 from tilting due to uneven spring force.

[0052] Through the above technical solution, this application effectively reduces the impact load on the structure of the vibration assembly 300 during operation by setting up the vibration base plate 303 and the buffer spring 304, avoiding loosening of the connecting parts or structural fatigue caused by long-term vibration. At the same time, the vertical vibration degree of freedom of the vibration platform 301 is guaranteed, ensuring the efficiency of bubble rupture and material filling during the degassing process of the solid buoyancy material, and improving the stability and consistency of the degassing process.

[0053] As some preferred embodiments, this application further proposes that the number of buffer springs 304 can be 2 to 5, arranged in a ring at intervals, with their lower ends fixedly welded to the vibration base plate 303 and their upper ends fixedly welded to the vibration platform 301. The range of the number of buffer springs 304 refers to limiting the number of springs to between 2 and 5, specifically using 3 or 4 springs symmetrically distributed, ensuring support stability while avoiding structural redundancy. The welding connection refers to the fixing of the two ends of the springs to the vibration base plate and vibration platform using a fusion welding process, specifically arc welding or laser welding, to eliminate the risk of loosening.

[0054] Specifically, when the vibration motor 302 drives the vibration platform 301 to generate vertical vibration, multiple buffer springs 304 arranged in a ring at intervals are synchronously compressed or stretched. Through uniformly distributed elastic deformation, they absorb vibration energy, avoiding vibration deviation caused by localized stress concentration. The number of springs is controlled within the range of 2 to 5, satisfying the support stiffness requirements while reducing energy loss caused by an excessive number of springs. The welded and fixed ends of the springs form a rigid connection, maintaining structural stability under continuous vibration load and preventing a decrease in vibration transmission efficiency due to loose bolts.

[0055] Through the above technical solution, this application effectively reduces the energy loss of the vibration platform 301 during vertical vibration, suppresses the resonance phenomenon of the body, and ensures a long-term stable connection between the buffer spring 304 and the vibration platform 301 and the vibration base plate 303 through welding connection, thus solving the problem of reduced degassing efficiency caused by structural loosening.

[0056] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes a vacuum assembly 400 including a vacuum pump 401 and a vacuum valve 402. The vacuum pump 401 is located outside the machine body and is connected to the vacuum valve 402 installed on the machine cover 200 through a pressure-resistant hose 403. It is also electrically connected to the controller 500.

[0057] Among them, vacuum pump 401 refers to a device that generates negative pressure mechanically, specifically a conventional rotary vane vacuum pump, which avoids resonance interference with vibrating components through its external placement. Pressure-resistant hose 403 refers to a conventional flexible connecting pipe with resistance to negative pressure deformation; this hose allows displacement when the cover 200 is opened and closed without affecting the seal. Vacuum valve 402 is an actuator that controls the on / off state of the vacuum pipeline; specifically, it can be a conventional electromagnetically driven ball valve, which enables rapid on / off control of the vacuum pump 401 and the machine body 100 cavity.

[0058] Specifically, the vacuum pump 401 is independently installed on the side or rear of the machine body 100. It is connected to one end of a pressure-resistant hose 403 via a flange interface, and the other end of the pressure-resistant hose 403 is connected to a vacuum valve 402 installed on the machine cover 200 via the same flange interface. When the machine cover 200 is closed, the pressure-resistant hose 403 maintains a natural bend to accommodate height changes when the cover is opened. Simultaneously, the controller 500 sends start / stop commands to the vacuum pump 401 and controls the operating parameters of the vibration assembly 400. During the vacuuming process, the vacuum valve 402 remains fully open. When the pressure reaches a set threshold, the controller 500 automatically activates the vibration assembly 400 to perform degassing.

[0059] In some embodiments, the connection between the pressure hose 403 and the cover 200 can be equipped with a quick-connect fitting, such as a conventionally known clamp-type stainless steel fitting, to facilitate disassembly during equipment maintenance. The base of the vacuum pump 401 can be fitted with shock-absorbing pads and mounted on the factory floor, such as a 5mm thick rubber pad, to reduce operating noise.

[0060] In some of these embodiments, such as Figure 1 As shown, this application further proposes that the test apparatus also includes a controller 500 detachably mounted on the main body 100. The controller 500 is electrically connected to the vibration motor 302 in the vibration assembly 300 and the vacuum pump 401 in the vacuum assembly 400. Detachable mounting means that the controller 500 is connected to the main body via a combination of slide rails and clips. Specifically, a conventional aluminum alloy slide rail and spring lock can be used to achieve quick assembly and disassembly, facilitating the separation of the controller 500 from the main unit during equipment maintenance. Electrical connection means that the controller 500 has a built-in multi-channel relay module, which interfaces with the power interfaces of the vibration motor 302 and the vacuum pump 401 through waterproof connectors to achieve stable transmission of control signals.

[0061] Specifically, the controller 500 can be a conventionally known PLC controller. The start / stop and frequency adjustment signals of the vibration motor 302 are output through the pulse width modulation circuit built into the controller 500. The start / stop and pumping speed of the vacuum pump 401 are controlled by the proportional-integral-derivative algorithm within the controller 500. The operation interface integrates a touch screen and physical knobs. After the stop parameters are set, the controller synchronously sends vibration intensity commands and vacuum adjustment commands according to the preset program, so that the bubble expansion rate of the material in the vacuum environment and the vibration crushing frequency are dynamically matched.

[0062] In summary, combining Figures 1 to 3 As shown, the experimental device of this utility model accelerates bubble bursting through the synergistic effect of the vibration component 300 and the vacuum component 400. At the same time, the movable structure improves the ease of operation. It has the advantage of improving the bubble elimination efficiency through the synergistic effect of vibration assistance and vacuum degassing. Furthermore, through the controller 500, which is electrically connected to the vibration motor 302 and the vacuum pump 401, the coordinated operation of each part can be controlled to realize the automated and efficient degassing process of the device.
