Description

Technical Field

[0001] This utility model relates to the field of vacuum technology, and in particular to a vacuum dehydration device for printing paper. Background Technology

[0002] Vacuum dewatering devices for printing paper are essential equipment in the papermaking and dyeing industries. They primarily utilize the principle of vacuum negative pressure, creating a pressure difference between the inside and outside of the paper to remove excess moisture, ensuring the paper's moisture content meets the requirements of subsequent production processes. By continuously extracting air from a specific space within the device using a vacuum pump, a negative pressure environment is quickly and effectively created, allowing the moisture in the printing paper to be drawn out under the pressure difference, thus achieving dewatering. This ensures the entire dewatering process is stable and efficient, facilitating smooth subsequent processing of the printing paper. By adding a specific working fluid to the liquid ring vacuum pump, it participates in the entire pumping and venting process during operation, acting as a working fluid. The medium circulates continuously, helping to achieve operations such as gas intake, compression, and exhaust. This allows the vacuum pump to efficiently complete the pumping task according to the set principles and processes, maintaining the internal vacuum state to better serve related applications such as vacuum dehydration of printed paper, ensuring the smooth implementation of functions such as dehydration. After adding liquid to the vacuum pump to the specified water level, the water supply pipe needs to be manually closed. Manual closure is prone to delays, causing liquid to continuously flow in and exceed the pump's normal capacity. Excessive liquid can easily cause abnormal thickness of the water ring, increase the impeller's rotational resistance, interfere with its normal rotational speed and angle, and ultimately reduce the vacuum pump's pumping efficiency, affecting related vacuum operations and hindering the normal operation of the production process.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1 Reference Figures 1-6 This is the first embodiment of the present invention, which provides a vacuum dehydration device for printing paper. The vacuum dehydration device for printing paper includes a main body component and a sealing component. The two components work together to automatically seal the water supply pipe after the vacuum pump adds liquid to a specified water level, preventing excessive liquid from entering. This stabilizes the impeller resistance, ensures the vacuum level, and helps the vacuum dehydration device to operate continuously and efficiently.

[0027] The main component 100 includes a vacuum pump 101, a gas delivery pipe 102 fixed to the top of the vacuum pump 101, and a water pipe 103 fixed to one side of the vacuum pump 101.

[0028] Vacuum pump 101 creates a vacuum or negative pressure environment by evacuating gas from a specific space to reduce its internal pressure, thus providing the necessary conditions for the dehydration of printed paper and ensuring the smooth operation of the corresponding process. Two gas supply pipes 102 are fixed to the top of vacuum pump 101; one is an inlet and the other an outlet. The inlet of gas supply pipe 102 is used to draw in external gas into vacuum pump 101 to provide conditions for evacuation, while the outlet is used to discharge the gas processed by vacuum pump 101, maintaining its evacuation capacity and vacuum environment. Water pipe 1... 03 is used to add or discharge liquid into the vacuum pump 101 to ensure the normal and stable operation of the vacuum pump 101. The vacuum pump 101 usually completes the pumping by connecting to a pipe in a specific space. The vacuum pump 101 uses the pipe as a gas transmission channel to continuously draw gas from the target space into the pump body. The gas is then processed and discharged through the operation of the internal structure, thereby achieving the purpose of reducing the air pressure in the target space and creating a vacuum or negative pressure environment. The vacuum pump 101 is existing technology and is common knowledge to those skilled in the art, so it will not be elaborated on here.

[0029] The sealing component 200 is disposed on the water pipe 103 and includes a sealing element 201. The sealing element 201 includes a sealing ball 2011, which is located inside the water pipe 103. A drive rod 2012 is fixed to the top of the sealing ball 2011, and a float ball 2013 is disposed inside the vacuum pump 101.

[0030] A water leakage hole is provided in the middle of the sealing ball 2011. By rotating the sealing ball 2011 so that its water leakage hole is aligned with the water pipe 103, water can be transported. By rotating the sealing ball 2011, the water pipe 103 can be sealed. When liquid is added to the vacuum pump 101 through the water pipe 103 to the water level, it can drive the float ball 2013 to move. At this time, the movement of the float ball 2013 can cause the sealing ball 2011 to rotate and seal the water pipe 103. The drive rod 2012 is designed to facilitate the user to rotate the sealing ball 2011.

[0031] Example 2 Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the enclosure component 200 also includes a support member 202, which includes a support tube 2021. The support tube 2021 is sleeved on the outside of the drive rod 2012, and the support tube 2021 and the drive rod 2012 are movably connected.

[0033] The support tube 2021 is fixed to the top of the water pipe 103. The support tube 2021 can support the drive rod 2012 and prevent the drive rod 2012 from shifting.

[0034] Specifically, a turntable 2022 is fixed to the top of the drive rod 2012, and a first torsion spring 2023 is fixed to the bottom of the turntable 2022. One end of the first torsion spring 2023 is fixed to the top of the support tube 2021.

[0035] When the drive rod 2012 is rotated to deliver liquid into the vacuum pump 101, the turntable 2022 is rotated, which applies a torsional force to the first torsion spring 2023, thereby driving the drive rod 2012 to rotate. The rotation of the drive rod 2012 drives the closed ball 2011 to rotate, thereby delivering liquid into the vacuum pump 101.

[0036] Specifically, a limit block 2024 is provided at the bottom of the turntable 2022, and a positioning disk 2025 is sleeved on the outside of the limit block 2024. The limit block 2024 and the positioning disk 2025 are movably connected.

[0037] When the closed ball 2011 rotates to deliver liquid into the vacuum pump 101, in order to prevent the force of the first torsion spring 2023 from causing the closed ball 2011 to rotate, the closed ball 2011 can be limited by engaging the limiting block 2024 and the turntable 2022. The positioning plate 2025 is sleeved on the outside of the support tube 2021. The positioning plate 2025 can support the limiting block 2024. Two sealing rings are fixed on the inner wall of the vacuum pump 101, respectively set on both sides of the closed ball 2011. When the closed ball 2011 is closed, it can squeeze the sealing rings, thereby ensuring the sealing performance.

[0038] Specifically, the bottom of the turntable 2022 is provided with a limiting groove 2024-1 corresponding to the limiting block 2024, and the limiting block 2024 is located in the limiting groove 2024-1.

[0039] The limiting block 2024 is set as an inclined surface, and the limiting groove 2024-1 is also set as an inclined surface. When the turntable 2022 is rotated to open the closing ball 2011, the limiting block 2024 can slide at the bottom of the limiting groove 2024-1. The engagement of the limiting block 2024 and the limiting groove 2024-1 can limit the turntable 2022 in one direction, preventing the force of the first torsion spring 2023 from driving the closing ball 2011 to rotate. After the vacuum pump 101 is filled with water to the specified level, the float 2013 will move. At this time, the movement of the float 2013 can drive the limiting block 2024 and the limiting groove 2024-1 to separate, thereby releasing the limitation on the turntable 2022. Then, the force of the first torsion spring 2023 can drive the closing ball 2011 to rotate, thereby closing the water pipe 103.

[0040] Example 3 Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, a pressure plate 2026 is fixed to the bottom of the limiting block 2024, a spring 2027 is fixed to the bottom of the pressure plate 2026, one end of the spring 2027 is fixed to the top of the positioning plate 2025, and a moving rod 2028 is fixed to the bottom of the limiting block 2024.

[0042] The moving rod 2028 is inserted into the bottom of the positioning plate 2025. The moving rod 2028 and the positioning plate 2025 are movably connected. The movement of the float 2013 can drive the moving rod 2028 to move. At this time, the movement of the moving rod 2028 can drive the limiting block 2024 and the limiting groove 2024-1 to separate. At the same time, it can drive the pressure plate 2026 to move. The movement of the pressure plate 2026 can apply a squeezing force to the spring 2027. After the water of the vacuum pump 101 is discharged, the float 2013 can return to its original position. Then, the rebound force of the spring 2027 can drive the limiting block 2024 and the limiting groove 2024-1 to engage and limit the turntable 2022.

[0043] Specifically, the enclosure component 200 also includes a connector 203, which includes a pull rope 2031, which is fixed to the bottom of the moving rod 2028.

[0044] The pull rope 2031 is inserted into one side of the vacuum pump 101 and into the top of the water pipe 103. A sealing ring is provided at the connection between the pull rope 2031 and the water pipe 103 to ensure sealing. The pull rope 2031 is movably connected to the vacuum pump 101 and the water pipe 103. The movement of the pull rope 2031 can drive the moving rod 2028 to move.

[0045] Specifically, a movable plate 2032 is provided at one end of the pull rope 2031, and a hinge rod 2033 is fixed on one side of the movable plate 2032. The hinge rod 2033 is rotatably connected to the inner wall of the water pipe 103 through a rotating shaft, and the hinge rod 2033 is fixed to one side of the float 2013.

[0046] A movable ball is fixed at one end of the pull rope 2031. The movable ball is movably connected to the movable plate 2032 in a ball-and-lock connection. When the float 2013 moves, it can drive the hinge rod 2033 to move. The movement of the hinge rod 2033 will drive the movable plate 2032 to move. The movement of the movable plate 2032 will pull the pull rope 2031, causing the movable rod 2028 to move. Then the limit on the turntable 2022 can be released. At this time, the force of the first torsion spring 2023 can close the closing ball 2011.

[0047] Specifically, a second torsion spring 2034 is fixed to one side of the hinge rod 2033, and one end of the second torsion spring 2034 is fixed to the inner wall of the water pipe 103.

[0048] When the hinge rod 2033 moves, it can apply a torsional force to the second torsion spring 2034. After the liquid in the vacuum pump 101 is discharged, the force of the second torsion spring 2034 can drive the hinge rod 2033 back to its original position for the next use.

[0049] Specifically, a fixed pulley 2035 is provided at the bottom of the pull rope 2031, and a fixing block 2036 is sleeved on the outside of the pull rope 2031. The pull rope 2031 and the fixing block 2036 are movably connected.

[0050] The fixed pulley 2035 is rotatably connected to the top of the water pipe 103 via a bearing, and the fixed block 2036 is fixed to the top of the water pipe 103. When the pull rope 2031 moves, it can move on the fixed pulley 2035 and the fixed block 2036, thereby supporting the pull rope 2031 and preventing it from deviating. A baffle is provided on one side of the float 2013, and a groove is provided at the bottom of the baffle to ensure liquid flow. The baffle is fixed to the inner wall of the vacuum pump 101. The baffle can protect the float 2013 and prevent the impeller from affecting the float when it rotates.

[0051] In use, the turntable 2022 needs to be rotated first to drive the drive rod 2012 to rotate. At this time, the rotation of the turntable 2022 can apply a torsional force to the first torsion spring 2023. At the same time, the limiting block 2024 can slide at the bottom of the limiting groove 2024-1. The engagement of the limiting block 2024 and the limiting groove 2024-1 can limit the turntable 2022 in one direction, preventing the force of the first torsion spring 2023 from rotating and causing the closing ball 2011 to rotate. The rotation of the drive rod 2012 drives the closing ball 2011 to rotate and open it, so that liquid can be delivered into the vacuum pump 101.

[0052] When liquid is added to the designated water level in the vacuum pump 101, the float 2013 moves. The float 2013 moves the hinge rod 2033, which in turn moves the moving plate 2032. The hinge rod 2033 applies a torsional force to the second torsion spring 2034. The moving plate 2032 pulls the pull rope 2031, causing the moving rod 2028 to move. This movement of the moving rod 2028 separates the limiting block 2024 from the limiting groove 2024-1. Simultaneously, it moves the pressure plate 2026, which applies a compressive force to the spring 2027, further separating the limiting block 2024 from the limiting groove 2024-1. Then the limiting force on the turntable 2022 can be released. Then, the force of the first torsion spring 2023 rotating drives the closing ball 2011 to rotate, thereby sealing the water pipe 103 to prevent liquid from continuing to be injected into the vacuum pump 101. When the impeller in the vacuum pump 101 is started or the liquid inside is discharged, the bottom of the vacuum pump 101 is provided with a drain port for drainage. At this time, the water level in the vacuum pump 101 changes, releasing the pressure on the float ball 2013. The force of the second torsion spring 2034 rotating can drive the hinge rod 2033 to return to its original position and release the pull rope 2031. Then, the force of the spring 2027 rebounding can drive the limiting block 2024 and the limiting groove 2024-1 to engage and limit the turntable 2022 for the next use.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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.
