Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and in particular to a draining device with an anti-accidental contact device. Background Technology

[0002] A vacuum system typically consists of user-point equipment, a vacuum buffer tank, a vacuum pump, and a vacuum pump water tank, all connected by pipelines. As the vacuum system operates, non-condensable gases from the user-point vacuum devolatilization or vacuum distillation equipment flow into the vacuum buffer tank, where most condense and accumulate as liquid. This liquid needs to be periodically drained or reused on the production line. However, draining this accumulated liquid requires shutting down the vacuum pump and evacuating the system, which significantly impacts the system's vacuum level and production efficiency. Therefore, a device needs to be designed that allows for liquid drainage without requiring shutdown, while also ensuring high safety and minimizing the risk of system downtime due to accidental operation.

[0006] The system includes a vacuum suction device, a vacuum buffer tank connected to the vacuum suction device, a drain tank connected to the vacuum buffer tank, a pipeline structure, a valve structure installed on the pipeline structure, and an anti-accidental contact device. The anti-accidental contact device includes multiple anti-accidental contact structures installed on one side of the valve structure and a control structure for controlling the opening or closing of each anti-accidental contact structure. When the anti-accidental contact structure is opened, it can restrict the operation of the valve structure. When the anti-accidental contact structure is closed, it can release the restriction on the operation of the valve structure.

[0007] The pipeline structure includes a first pipeline with one end connected to the top of the vacuum buffer tank and the other end connected to the top of the drain tank, and a second pipeline with one end connected to the bottom of the vacuum buffer tank and the other end connected to the top of the drain tank; the valve structure includes a first vent valve and a pressure balancing valve disposed on the first pipeline, and a first drain valve disposed on the second pipeline;

[0008] When the drain tank is evacuated, the control structure can control the anti-accidental contact structure of the first vent valve and the pressure balance valve to close, and at the same time, the control structure controls the anti-accidental contact structure of the first drain valve to open to prevent accidental contact; when the vacuum buffer tank is drained, the control structure can control the anti-accidental contact structure of the first drain valve to close, and at the same time, the control structure controls the anti-accidental contact structure of the first vent valve and the pressure balance valve to open to prevent accidental contact.

[0009] According to some embodiments of the present invention, the anti-accidental touch device includes an operation panel, the first vent valve, the pressure balancing valve and the first drain valve are all disposed on the operation panel, the anti-accidental touch structure includes a cover plate for blocking the control area, and the control structure is used to control the cover plate to flip or move above the control area of ​​the valve structure.

[0010] According to some embodiments of the present invention, the control structure includes a plurality of first gears connected to each of the cover plates, a second gear meshing with each of the first gears, a third gear rotating synchronously with each of the second gears, and a rack meshing with the third gear.

[0012] According to some embodiments of this utility model, both the vacuum buffer tank and the drain tank are equipped with liquid level sensors.

[0013] According to some embodiments of the present invention, a vacuum pump for extracting air from the drain tank is provided on one side of the drain tank.

[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0026] An embodiment of this utility model provides a draining device with an anti-accidental contact mechanism, such as... Figure 1-4 As shown, it includes:

[0027] The system includes a vacuum suction device 1, a vacuum buffer tank 2 connected to the vacuum suction device 1, a drain tank 3 connected to the vacuum buffer tank 2, a pipeline structure 4, a valve structure 5 installed on the pipeline structure 4, and an anti-accidental contact device 6. The anti-accidental contact device 6 includes multiple anti-accidental contact structures 601 installed on one side of the valve structure 5 and a control structure 602 for controlling the opening or closing of each anti-accidental contact structure 601. When the anti-accidental contact structure 601 is open, it can restrict the operation of the valve structure 5. When the anti-accidental contact structure 601 is closed, it can release the restriction on the operation of the valve structure 5.

[0028] Pipeline structure 4 includes a first pipe 401 connected at one end to the top of vacuum buffer tank 2 and at the other end to the top of drain tank 3, and a second pipe 402 connected at one end to the bottom of vacuum buffer tank 2 and at the other end to the top of drain tank 3; valve structure 5 includes a first vent valve 501 and a pressure balancing valve 502 provided on the first pipe 401, and a first drain valve 503 provided on the second pipe 402.

[0029] When the drain tank 3 is evacuated, the control structure 602 can control the anti-accidental contact structure 601 of the first vent valve 501 and the pressure balance valve 502 to close, and at the same time, the control structure 602 controls the anti-accidental contact structure 601 of the first drain valve 503 to open to prevent accidental contact; when the vacuum buffer tank 2 is drained, the control structure 602 can control the anti-accidental contact structure 601 of the first drain valve 503 to close, and at the same time, the control structure 602 controls the anti-accidental contact structure 601 of the first vent valve 501 and the pressure balance valve 502 to open to prevent accidental contact.

[0030] The vacuum buffer tank 2 in this drainage device is connected to a vacuum suction device 1. During system operation, the vacuum suction device 1 continuously draws a vacuum, and both non-condensable and condensate accumulate at the bottom of the vacuum buffer tank 2. The first pipe 401 connects the vacuum buffer tank 2 and the drainage tank 3. Before drainage, the pressure inside the vacuum buffer tank 2 and the drainage tank 3 needs to be balanced. When vacuuming the drain tank 3, the first vent valve 501 is opened, and the vacuum suction device 1 connected to the vacuum buffer tank 2 is used to vacuum the drain tank 3 until the pressure balancing valve 502 is balanced. After the pressure balancing valve 502 is balanced, when the vacuum buffer tank 2 is draining, the first vent valve 501 and the pressure balancing valve 502 need to be closed, and then the first drain valve 503 is opened so that the accumulated liquid flows into the drain tank 3 from the second pipe 402. When vacuuming the drain tank 3, if the first drain valve 503 is accidentally opened, it may cause high-pressure jetting of liquid. When the vacuum buffer tank 2 is draining, if the first vent valve 501 and the pressure balancing valve 502 are opened, it may cause liquid backflow or abnormal pressure, thus suspending the system and affecting production. Therefore, the anti-accidental operation device 6 is set up to prevent accidental operation.

[0031] When the drain tank 3 is evacuated, the anti-accidental contact structure 601 of the first vent valve 501 and the pressure balancing valve 502 is closed by the control structure 602, allowing normal operation of these valves. Simultaneously, to prevent accidental contact of the first drain valve 503, the anti-accidental contact structure 601 of the first drain valve 503 is opened by the control structure 602, blocking the control area of ​​the valve and preventing opening or rotation. Conversely, when the anti-accidental contact structure 601 of the first drain valve 503 is closed by the control structure 602, the anti-accidental contact structures 601 of the first vent valve 501 and the pressure balancing valve 502 are opened by the control structure 602, ensuring that these two valves cannot be opened simultaneously, thus achieving an interlocking function. The anti-accidental contact structure 601 effectively restricts valve operation, avoiding safety hazards caused by operator error. In small systems where valve structure 5 requires manual operation, a mechanical blocking structure can be used to achieve the anti-accidental contact function. Specifically, the area controlling the valve can be directly covered or opened using a cover plate 604 or similar structure via a mechanical control structure 602. Alternatively, a block or baffle that can be inserted into the area controlling the valve can be used for blocking control. The mechanical anti-misoperation structure 601 is inexpensive and provides good physical anti-misoperation protection. Furthermore, an automatic control structure 602, such as a drive motor or relay, can be added to link and control multiple valve structures 5 together.

[0032] In some embodiments, such as Figure 2-3 As shown, the anti-accidental touch device 6 includes an operation panel 603. The first vent valve 501, the pressure balancing valve 502, and the first drain valve 503 are all mounted on the operation panel 603. The anti-accidental touch structure 601 includes a cover plate 604 for blocking the control area. The control structure 602 is used to control the cover plate 604 to flip or move to the top of the control area of ​​the valve structure 5.

[0033] The first vent valve 501, pressure balancing valve 502, and first drain valve 503 are centrally located on the operation panel 603, making the entire valve operation area more compact and centralized. This facilitates unified management and monitoring by operators, and also makes it easier to maintain and repair the valves when needed, improving operational convenience and efficiency. The anti-accidental touch structure 601 uses a cover plate 604 to block the valve structure 5. This physical blocking method can directly and effectively prevent operators from accidentally touching the valve at inappropriate times, avoiding system failures or safety hazards caused by misoperation. The cover plate 604 has a simple and easy-to-implement design, low cost, and good reliability and durability. The control structure 602 can precisely control the flipping or movement of the cover plate 604, allowing it to flexibly cover or expose the control area of ​​the valve structure 5.

[0034] Furthermore, such as Figure 2-4As shown, the control structure 602 includes a plurality of first gears 605 connected to each cover plate 604, a second gear 606 meshing with each first gear 605, a third gear 607 rotating synchronously with each second gear 606, and a rack 608 meshing with the third gear 607. The rack 608 can slide up and down or left and right, while the first gears 605 rotate to drive the cover plate 604 to flip up and down or left and right.

[0035] Specifically, the control structure 602 also includes a synchronous transmission shaft connecting the second gear 606 and the third gear 607. Through the combined transmission of the first gear 605, the second gear 606, the synchronous transmission shaft, the third gear 607, and the rack 608, the rack 608 is driven to synchronously rotate each of the third gears 607, thereby driving the second gear 606 connected to the third gear 607 to rotate synchronously, which in turn drives the first gear 605 meshing with the second gear 606 to rotate. This allows for precise control of the flipping action of each cover plate 604 fixed to the first gear 605, ensuring that the cover plate 604 accurately flips to the designated position when needed, thereby reliably blocking or releasing the valve and effectively preventing misoperation. The mechanical transmission structure is relatively simple, easy to maintain and repair, and has a low cost. In practice, the first gear 605 on one side of the first vent valve 501 and the pressure balancing valve 502 is located on the left side of its control area and is connected to a cover plate 604, while the first gear 605 of the first drain valve 503 is located on the right side of its control area and is connected to a cover plate 604. When the rack 608 moves to the right, the cover plate 604 covering the first vent valve 501 and the pressure balancing valve 502 flips open to the left, exposing the control area; while the cover plate 604 at the first drain valve 503 flips to the right, covering the control area.

[0036] Furthermore, such as Figure 4 As shown, the rack 608 includes multiple meshing portions 609 that mesh with the third gear 607 and limiting portions 610 disposed on both sides of the meshing portions 609. The limiting portions 610 are used to limit the rotation distance of the third gear 607.

[0037] The limiting part 610 is set on both sides of the third gear 607, which can conveniently limit the rotation distance of the third gear 607. It can effectively prevent the gear from rotating too much and causing the cover plate 604 to be damaged due to excessive flipping angle. It ensures that the cover plate 604 is always in the correct working position. The rack 608 with the limiting part 610 has a simple structure and is easy to process and install.

[0038] Furthermore, such as Figure 1 As shown, both the vacuum buffer tank 2 and the drain tank 3 are equipped with liquid level sensors.

[0039] The liquid level sensor can monitor the liquid level in the vacuum buffer tank 2 and the drain tank 3 in real time, providing the system with accurate liquid level information. This allows operators or automated control systems to monitor the accumulation and discharge of liquid at any time, thereby achieving precise control of the draining process. Specifically, the sensing end of the liquid level sensor extends into the tank body, and the extended display structure is set on the operation panel 603 for easy integrated management.

[0040] In some embodiments, such as Figure 1 As shown, a vacuum pump 504 for extracting air from the drain tank 3 is provided on one side of the drain tank 3.

[0041] The vacuum pump 504 can extract the air from the drain tank 3 in advance, so that the drain tank 3 can quickly establish a vacuum environment, thereby accelerating the vacuum balance between the vacuum buffer tank 2 and the drain tank 3, further improving the draining efficiency, and also reducing the impact on the vacuum level of the entire system.

[0042] Furthermore, such as Figure 1 As shown, the second pipe 402 is provided with a filter structure 7 for filtering impurities in the liquid.

[0043] Since impurities may remain in the pipes or tanks, the filter structure 7 allows the liquid discharged into the drain tank 3 to be directly recycled.

[0044] Furthermore, the filter structure 7 is a multi-layer filter.

[0045] Multi-layer filters can effectively intercept impurities in liquids, ensuring higher purity of discharged liquids and preventing impurities from entering subsequent equipment or pipelines and causing blockages or damage. Through multi-layer filtration, impurities of different particle sizes can be filtered in stages, improving filtration efficiency and precision. Furthermore, a backwashing system can be added to facilitate subsequent flushing and discharge of impurities.

[0046] Furthermore, such as Figure 1 As shown, the pipeline structure 4 includes a third pipeline 403 located below the filter structure 7 and connected to the second pipeline 402, and the valve structure 5 includes a second drain valve 505 located on the third pipeline 403 for discharging impurity liquid.

[0047] The second drain valve 505 allows the filtered impurities to be discharged or directed to other structures connected to the third pipe 403, enabling separate collection or further processing of the filtered liquid.

[0048] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
