Description

Technical Field

[0001] This utility model relates to the field of degassing technology, specifically to a novel vacuum degassing device. Background Technology

[0002] When a vacuum degasser is in operation, the vacuum pump creates negative pressure inside the vacuum tank through suction, drawing in media such as slurry. During this process, the rapid flow of gas and the jetting and collision of media generate significant noise. This intense noise is often accompanied by equipment vibration, thus shortening the equipment's lifespan.

[0003] In high-noise environments, it is difficult for operators to accurately judge the operating status of equipment. In addition, noise can harm the hearing health of operators when debugging equipment or performing some manual operations. Utility Model Content

[0029] Optionally, it also includes:

[0030] A sealed chamber is mounted on the frame and has a liquid storage cavity. The liquid storage cavity has a first liquid outlet and an air outlet. One end of the air inlet pipe is mounted on the vacuum pump, and the other end is connected to the air outlet. The first liquid outlet is used for liquid discharge.

[0031] A centrifugal rotating component is rotatably disposed inside the liquid storage cavity. The centrifugal rotating component has a hollow internal structure and has a liquid inlet and a second liquid outlet. After the centrifugal rotating component rotates, the liquid abuts against the inner wall of the liquid storage cavity through the second liquid outlet.

[0032] The liquid inlet pipe is connected to the liquid inlet.

[0033] Optionally, it also includes:

[0036] A baffle is disposed inside the liquid storage cavity, and the centrifugal rotating component is rotatably disposed on the baffle. After the centrifugal rotating component rotates, it causes the liquid to come into contact with the baffle.

[0037] The working principle and beneficial effects of this utility model are as follows:

[0038] In this invention, to address the issue of excessive noise in vacuum degassers in related technologies, the frame is first constructed to ensure structural stability and the ability to withstand the weight of subsequent equipment components and vibrations generated during operation. The vacuum pump is then installed on the frame at a pre-defined position and secured using bolts and other connectors, ensuring a firm and level installation. The inlet pipe is connected to the vacuum pump's inlet, and the connection is sealed with sealant to prevent gas leakage. Next, the threaded end of one sound-insulating component is screwed into the inlet pipe, facing the vacuum pump's inlet direction, to block noise generated during the intake process. The outlet pipe is connected to the vacuum pump's outlet and sealed accordingly. Finally, the threaded end of another sound-insulating component is screwed into the outlet pipe, facing the outlet direction, to reduce exhaust noise.

[0039] The vacuum degasser is activated, and the vacuum pump begins operation, drawing outside gas into the pump through the inlet pipe. As the gas enters the inlet pipe, some noise is absorbed and reflected due to the obstruction of sound propagation by the sound-insulating components, reducing the amount of noise transmitted to the surrounding environment. After being processed within the vacuum pump, the gas is discharged through the outlet pipe. At this point, the sound-insulating components on the outlet pipe again function, suppressing the noise generated by the discharged gas, further reducing the noise ultimately released into the external environment.

[0040] The sound insulation components effectively reduce the transmission of noise generated during the vacuum pump's intake and exhaust processes. By installing sound insulation components on both the intake and exhaust pipes, double blocking is achieved at both the source and the propagation path of the noise. The threaded connection of the sound insulation components makes installation and removal convenient. Attached Figure Description

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] Reference Figures 1-2 This is the first embodiment of the present utility model, which proposes...

[0054] A novel vacuum degasser includes a frame 1; a vacuum pump 2 is mounted on the frame 1 and has an inlet pipe 3 and an outlet pipe; two sound insulation components 5 are provided, one end of which is a threaded end 51 and the other end is a sound insulation end 52. The threaded end 51 is threaded onto the inlet pipe 3 and / or the outlet pipe 4, and the sound insulation end 52 is used for sound insulation.

[0055] In this embodiment, to address the issue of excessive noise in vacuum degassing devices in related technologies, the frame 1 is first constructed to ensure its structural stability and ability to withstand the weight of subsequent equipment components and vibrations generated during operation. The vacuum pump 2 is then installed on the frame 1 at a pre-defined position and secured using bolts and other connectors, ensuring the vacuum pump 2 is firmly installed and level. The inlet pipe 3 is connected to the inlet of the vacuum pump 2, and the connection is sealed with sealant or other sealing materials to prevent gas leakage. Then, the threaded end 51 of one of the sound-insulating components 5 is screwed into the inlet pipe 3, with the sound-insulating end 52 facing the air intake direction of the vacuum pump 2, to block noise generated during the air intake process. The outlet pipe 4 is connected to the outlet 123 of the vacuum pump 2, and similarly sealed. Finally, the threaded end 51 of the other sound-insulating component 5 is screwed into the outlet pipe 4, with the sound-insulating end 52 facing the air outlet direction, to reduce exhaust noise.

[0056] The vacuum degasser is activated, and vacuum pump 2 begins operation. Outside gas is drawn into vacuum pump 2 through inlet pipe 3. As the gas enters inlet pipe 3, some noise is absorbed and reflected due to the obstruction of sound propagation by the sound-insulating end 52 of the sound-insulating component 5, reducing the amount of noise transmitted to the surrounding environment. After being processed within vacuum pump 2, the gas is discharged through outlet pipe 4. At this point, the sound-insulating component 5 on outlet pipe 4 again functions, suppressing the noise generated by the discharged gas, further reducing the noise ultimately released into the external environment.

[0057] The sound insulation component 5 effectively reduces the transmission of noise generated during the intake and exhaust processes of the vacuum pump 2. By installing the sound insulation component 5 on both the intake pipe 3 and the exhaust pipe 4, double blocking is achieved from both the source and the propagation path of the noise. Since the sound insulation component 5 uses a threaded connection, it is easy to install and remove.

[0058] Reference Figure 3 Furthermore, the second half soundproof cover 7 is rotatably mounted on the first half soundproof cover 6, and a receiving space 71 is formed between the first half soundproof cover 6 and the second half soundproof cover 7. The receiving space 71 is used to receive the air inlet pipe 3 and / or the air outlet pipe 4.

[0059] In this embodiment, the second half-soundproof cover 7 is mounted on the first half-soundproof cover 6 via a hinge or other rotating connecting component, allowing the second half-soundproof cover 7 to rotate relative to the first half-soundproof cover 6. Rotating the second half-soundproof cover 7 opens or closes it relative to the first half-soundproof cover 6, thereby opening or closing the accommodating space 71. When open, the air inlet pipe 3 and the air outlet pipe 4 are enclosed within it. Sealing materials such as sealing strips are installed at the contact edges of the first half-soundproof cover 6 and the second half-soundproof cover 7 to ensure the airtightness of the accommodating space 71 and prevent noise leakage from gaps.

[0060] While the gas flows through the inlet pipe 3 and outlet pipe 4, generating noise, the enclosed space 71 formed by the first half-soundproof enclosure 6 and the second half-soundproof enclosure 7 further isolates the noise. Due to the presence of the soundproof enclosure, the noise is confined within the space 71 and reflects multiple times on the inner wall of the enclosure. After absorption and attenuation by the soundproof enclosure material, the amount of noise transmitted to the external environment is greatly reduced.

[0061] The synergistic effect of the dual sound insulation structure significantly enhances the overall noise reduction effect. The sound insulation component 5 addresses the noise source locally on the air inlet pipe 3 and the air outlet pipe 4, while the first half sound insulation cover 6 and the second half sound insulation cover 7 provide macroscopic sound insulation for the entire pipeline area, forming a comprehensive noise blocking system. This greatly improves the working environment for workers, reduces the risk of noise damage to workers' hearing, and enhances work comfort and production safety.

[0062] Reference Figure 4 Furthermore, both the first half-soundproof enclosure 6 and the second half-soundproof enclosure 7 include a base layer 72; a first soundproof layer 73 is disposed outside the base layer 72; a second soundproof layer 74 is disposed outside the first soundproof layer 73; and a support layer 75 is disposed outside the second soundproof layer 74.

[0063] In this embodiment, the assembly materials for the first half-soundproof enclosure 6 are prepared. First, the base layer 72 material is cut and processed according to the design dimensions to form the basic shape of the first half-soundproof enclosure 6. The first sound insulation layer 73 material (such as sound-absorbing cotton) is evenly wrapped around the base layer 72. The sound-absorbing cotton is firmly attached to the base layer 72 using glue or special fasteners, ensuring no gaps or wrinkles, so that the sound-absorbing cotton can fully exert its sound absorption function. A second sound insulation layer 74 material (such as a rubber damping layer) is wrapped around the first sound insulation layer 73. This layer is mainly used to reduce vibration propagation and absorb noise of specific frequencies. A bonding process is used to ensure that the rubber damping layer tightly wraps around the first sound insulation layer 73. Finally, the support layer 75 material (such as a metal frame) is wrapped around the second sound insulation layer 74 to provide sufficient strength and rigidity for the entire soundproof enclosure. Assemble the second half of the soundproof cover 7 using the same steps. After completion, install the second half of the soundproof cover 7 onto the first half of the soundproof cover 6 via hinges or other rotating connecting parts. Adjust the rotation flexibility so that the two can be tightly closed to form a receiving space 71, enclosing the air inlet pipe 3 and the air outlet pipe 4, and install sealing strips on the contact edges to ensure sealing.

[0064] The multi-layered structural design achieves noise reduction. The sound-absorbing cotton in the first sound insulation layer 73 has excellent absorption capabilities for high-frequency noise, effectively reducing sharp high-frequency noise generated by gas flow and component friction. The rubber damping layer in the second sound insulation layer 74 focuses on blocking mid-to-low frequency noise and vibration attenuation, significantly suppressing low-frequency humming noise generated by the operation of the vacuum pump 2. The combination of the two achieves effective control of noise over a wide frequency range. The support layer 75 provides strong mechanical protection for the soundproof enclosure. In industrial environments, vacuum degassing devices may face various external impacts, vibrations, and internal pressure changes. The metal frame structure of the support layer 75 can effectively withstand these forces, preventing the soundproof enclosure from deforming or being damaged by external forces, ensuring the long-term stability of the sound insulation performance of the enclosure.

[0065] Furthermore, the base layer 72 is a bendable structure.

[0066] In this embodiment, since the air inlet pipe 3 and the air outlet pipe 4 are bent structures, in order to achieve the versatility of the first half soundproof cover 6 and the second half soundproof cover 7, the base layer 72 is designed to be bendable. When covering the air inlet pipe 3 or the air outlet pipe 4, if the air inlet pipe 3 or the air outlet pipe 4 is bent, the base layer 72 can be bent so that the base layer 72 and the air inlet pipe 3 or the air outlet pipe 4 have the same structure, which makes it convenient to cover the air inlet pipe 3 or the air outlet pipe 4.

[0067] Reference Figures 5-6 Furthermore, there are several steel sheets 751, all of which are wrapped around the second sound insulation layer 74. The steel sheets 751 have a semi-circular structure, and several steel sheets 751 are arranged sequentially along the axial direction. The steel sheets 751 of the first semi-sound insulation cover 6 are rotatably mounted on the steel sheets 751 of the second semi-sound insulation cover 7.

[0068] In this embodiment, since the support layer 75 is a rigid structure, in order to achieve bending of the support layer 75, this embodiment designs the support layer 75 as several steel sheets 751 arranged sequentially. When the base layer 72 bends, the steel sheets 751 adjust their state in a timely manner without interfering with the bending of the base layer 72. Several semi-circular steel sheets 751 are arranged sequentially along the axial direction outside the second sound insulation layer 74. For the steel sheets 751 of the first half sound insulation cover 6, a pivot or hinge structure is installed at one end so that it can be rotatably connected to the steel sheets 751 of the second half sound insulation cover 7. When installing the steel sheets 751, it is necessary to ensure that the spacing between each steel sheet 751 is uniform and meets the design requirements. Assemble the second half sound insulation cover 7 according to the same steps and processes, and connect the steel sheets 751 of the second half sound insulation cover 7 to the steel sheets 751 of the first half sound insulation cover 6 through pivots or hinges to form a support structure that can rotate relative to each other. Sealing strips are installed on the edges of the first half soundproof cover 6 and the second half soundproof cover 7. When the two are closed, a sealed receiving space 71 is formed, which encloses the air inlet pipe 3 and the air outlet pipe 4. The rotation of the steel sheet 751 will not affect the bending action of the base layer 72 when subjected to external force or due to its own deformation.

[0069] Furthermore, one end of the steel sheet 751 is a protrusion 752 and the other end is a groove 753, with adjacent protrusions 752 used to engage with the groove 753.

[0070] In this embodiment, to prevent gaps from forming between the bent steel sheets 751, which would affect the sound insulation effect, the steel sheets 751 are designed with a protrusion 752 at one end and a groove 753 at the other end. The protrusions 752 of adjacent steel sheets 751 are inserted into the grooves 753 of adjacent steel sheets 751, and the grooves 753 are relatively large. The protrusions 752 can have room to move within the grooves 753 as the steel sheets 751 are bent. To enhance the sound insulation effect, a rubber pad can be designed between the protrusions 752 and the grooves 753. The rubber pad can deform to provide room to move for the protrusions 752. At the same time, the rubber pad can be reset to ensure a tight connection between adjacent steel sheets 751, preventing gaps between the steel sheets 751 from affecting the sound insulation effect.

[0071] Furthermore, the first connecting piece 8 has a hook head 81; the first connecting rod 9 has several of them, one end of which is set on the steel sheet 751 of the first half soundproof cover 6, and the other end is slidably set on the first connecting piece 8; the second connecting piece 10 has a hook groove 101, and the hook head 81 is used to engage in the hook groove 101; the second connecting rod 11 has several of them, one end of which is set on the steel sheet 751 of the second half soundproof cover 7, and the other end is slidably set on the second connecting piece 10.

[0072] In this embodiment, to connect the first half-soundproof cover 6 and the second half-soundproof cover 7, the first connecting piece 8 and the second connecting piece 10 are designed as deformable structures. When the first connecting piece 8 and the second connecting piece 10 bend along with the base layer 72, the first connecting rod 9 slides relative to the first connecting piece 8 and the second connecting rod 11 slides relative to the second connecting piece 10, ensuring that the steel sheet 751 bends synchronously with the base layer 72. When connecting the first half-soundproof cover 6 and the second half-soundproof cover 7, the hook head 81 is hooked into the hook groove 101 for fixation. When disassembly is required, simply remove the hook head 81 from the hook groove 101. The structure of the hook head 81 and the hook groove 101 in this embodiment makes the first half-soundproof cover 6 and the second half-soundproof cover 7 easy to disassemble and reusable.

[0073] Reference Figure 7 Furthermore, the sealed chamber 12 is mounted on the frame 1 and has a liquid storage cavity 121. The liquid storage cavity 121 has a first liquid outlet 122 and an air outlet 123. One end of the air inlet pipe 3 is mounted on the vacuum pump 2, and the other end is connected to the air outlet 123. The first liquid outlet 122 is used for liquid discharge. The centrifugal rotating component 13 is rotatably mounted inside the liquid storage cavity 121. The centrifugal rotating component 13 has a hollow internal structure and has a liquid inlet 131 and a second liquid outlet 132. After the centrifugal rotating component 13 rotates, the liquid abuts against the inner wall of the liquid storage cavity 121 through the second liquid outlet 132. The liquid inlet pipe 14 is connected to the liquid inlet 131, and the liquid flows into the liquid storage cavity 121 through the second liquid outlet 132. The liquid outlet pipe 15 is mounted on the first liquid outlet 122, which is located in the middle of the liquid storage cavity 121. The baffle 16 is disposed in the liquid storage cavity 121, and the centrifugal rotating component 13 is rotatably disposed on the baffle 16. After the centrifugal rotating component 13 rotates, it causes the liquid to come into contact with the baffle 16.

[0074] In this embodiment, the sealed chamber 12 is fixed on the frame 1, and its internal liquid storage cavity 121 can hold a certain amount of liquid. One end of the air inlet pipe 3 is connected to the vacuum pump 2. After the vacuum pump 2 is turned on, it can connect with the air outlet 123 of the sealed chamber 12 through the air inlet pipe 3, thereby forming a vacuum negative pressure environment in the liquid storage cavity 121. The liquid is then drawn from the liquid inlet pipe 14 into the hollow structure of the centrifugal rotating component 13. As the centrifugal rotating component 13 rotates at high speed, the liquid is thrown out at high speed through the second liquid outlet 132 under the action of centrifugal force, and makes forceful contact with the inner wall of the liquid storage cavity 121. At this time, because the liquid storage cavity 121 is a vacuum environment, the gas in the liquid quickly escapes and is extracted by the vacuum pump 2. The liquid flows downward into the liquid storage cavity 121 and flows out through the liquid outlet pipe 15.

[0075] The baffle 16 is made of high-strength, corrosion-resistant material and is installed inside the liquid storage cavity 121. The centrifugal rotating component 13 is stably rotated on the baffle 16. When the centrifugal rotating component 13 rotates, it drives some liquid from the inner wall of the liquid storage cavity 121 onto the baffle 16, further promoting gas separation and escape. At the same time, some liquid directly hits the baffle 16, increasing the gas absorption rate.

[0076] The high-speed rotation of the centrifugal rotor 13 and the vacuum environment within the liquid storage cavity 121 work together to rapidly separate and extract the gas from the liquid, significantly improving degassing efficiency. The baffle 16 further aids in gas separation and enhances the equipment's operational stability. The overall structure is compact, with all components working effectively together, making it adaptable to different production sites and process requirements.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
