Description

Technical Field

[0001] This application relates to the technical field of condensate recovery in air compressor systems, and in particular to a buffer tank anti-clogging control system. Background Technology

[0002] Air compressors are typically paired with dryers in subsequent processes to filter moisture from the air. To ensure stable operation of the air compressor and maintain a certain level of moisture in the air product, the drainage points of the paired dryers are currently designed for continuous discharge, meaning that the condensate from the dryer is quickly drained away.

[0003] In related technologies, there are also solutions that utilize water collection devices to recover condensate, that is, using water collection devices connected to a matching dryer to achieve the effect of buffering condensate.

[0004] Regarding the aforementioned technologies, the dryer is directly connected to the water collection device, allowing the condensate produced by the dryer to flow directly into the collection device. However, the condensate itself contains rust and slag, and when excessive condensate accumulates in the collection device, it can easily cause blockage, making it impossible to smoothly transport and recycle the condensate. Summary of the Invention

[0005] To help solve the problem of easy clogging in water collection devices, this application provides a buffer tank anti-clogging control system.

[0006] The buffer tank anti-clogging control system provided in this application adopts the following technical solution:

[0007] A buffer tank anti-clogging control system, including

[0008] A buffer tank, wherein a liquid level sensor is installed inside the buffer tank;

[0009] The main inlet pipe is connected to the side wall of the buffer tank near the top;

[0010] A drain pipe is connected to the bottom of the buffer tank, and a first emergency drain valve is installed on the drain pipe near the outlet.

[0011] A main outlet pipe is connected to the side wall of the branch drain pipe, and an outlet valve is installed on the main outlet pipe;

[0012] The control module is electrically connected to a liquid level sensor, a first emergency drain valve, and a water outlet valve. When the water level in the buffer tank reaches a set height, the water outlet valve opens. The liquid level sensor monitors the water level in the buffer tank. If the water level in the buffer tank drops slowly or not at all, the control module issues an alarm. When the water level in the buffer tank reaches an over-high alarm level, the control module issues an alarm and controls the first emergency drain valve to open. Once the water level in the buffer tank drops to the normal level, the first emergency drain valve closes.

[0013] By adopting the above technical solution, once the water level in the buffer tank reaches the set height, the condensate in the buffer tank needs to be transferred and recycled. At this time, the outlet valve opens, and the condensate is transported to the recycling point through the main outlet pipe. Simultaneously, the level sensor monitors the water level in the buffer tank. If the water level in the buffer tank drops slowly or not at all within a certain period of time, it indicates that the buffer tank may be blocked. At this time, the control module issues an alarm message, and the staff checks the abnormality and performs manual drainage operations. When the water level in the buffer tank reaches the high alarm level, the control module controls the first emergency drain valve to open, using pressure to discharge the condensate from the bottom of the buffer tank, simultaneously removing the blockage at the bottom of the buffer tank, thus solving the problem of easy blockage in the buffer tank. This application solution has high monitoring accuracy and convenient control, and can promptly discharge rust and slag from the buffer tank, reducing the occurrence of buffer tank blockage and ensuring the normal operation of the supporting dryer.

[0014] Optionally, the buffer tank includes a first buffer tank and a second buffer tank. The first buffer tank is connected to the main water inlet pipe, and an intermediate connecting pipe connects the first buffer tank and the second buffer tank. An intermediate discharge valve is installed on the intermediate connecting pipe, and the intermediate discharge valve is electrically connected to the control module.

[0015] By adopting the above technical solution, when the bottom of the first buffer tank becomes blocked, preventing the smooth discharge of condensate, the control module opens the intermediate discharge valve, allowing the condensate to flow into the second buffer tank through the intermediate connecting pipe. The second buffer tank then buffers and discharges the condensate. This solution ensures the continuous operation of the compressed air system and improves system reliability.

[0016] Optionally, the first buffer tank is equipped with a stirring device, which is used to scrape the inner wall of the buffer tank and stir the condensate in the buffer tank. The stirring device is electrically connected to the control module. When the water level in the buffer tank drops slowly or does not drop, the control module controls the stirring device to stir. When the water level in the buffer tank reaches the high alarm level, the control module controls the intermediate discharge valve to open, and some of the condensate flows from the first buffer tank into the second buffer tank.

[0017] By adopting the above technical solution, when the water level in the buffer tank drops slowly or not at all, the stirring device agitates the condensate. If the condensate can be normally recovered through the main outlet pipe after agitation, the waste of condensate can be reduced and the recovery rate improved. If the water level in the buffer tank still drops slowly or not at all after agitation, it indicates that the first buffer tank is severely clogged. At this time, the intermediate drain valve opens, and some condensate flows from the first buffer tank into the second buffer tank. The second buffer tank is then used to recover and transfer the condensate, improving the stability of the system.

[0018] Optionally, a float filter screen is installed inside the second buffer tank, and the float filter screen is located below the outlet of the intermediate connecting pipe; a limiting block for limiting the height of the float filter screen is provided on the side wall of the second buffer tank near the outlet of the intermediate connecting pipe; an emergency drain pipe is connected to the side wall of the second buffer tank near the height of the intermediate connecting pipe; a second emergency drain valve is installed on the emergency drain pipe; the second emergency drain valve is electrically connected to the control module; and the main outlet pipe is connected to the bottom of the second buffer tank.

[0019] By adopting the above technical solution, after the first buffer tank becomes clogged, some condensate flows from the first buffer tank into the second buffer tank. The condensate impacts the float filter screen, which filters out rust and debris from the condensate. As the water level rises, the float filter screen rises with it. When the float filter screen reaches the limit block, the second emergency drain valve opens, and the water flow impacts the surface of the float filter screen, flushing away rust and debris into the emergency drain pipe. After a period of discharge, the second emergency drain valve closes, and the water level continues to rise. When it reaches the predetermined height, the outlet valve opens, recovering the clean condensate and reducing the occurrence of buffer tank clogging. This solution allows clean condensate to accumulate at the bottom of the second buffer tank, while rust and debris remain at the top, facilitating the removal of rust and debris with minimal water usage and further enhancing the condensate recovery effect.

[0020] Optionally, multiple limiting blocks are provided, with the limiting block closer to the intermediate connecting pipe having a higher height than the limiting block closer to the emergency discharge pipe.

[0021] By adopting the above technical solution, this setting allows the float filter screen to tilt downwards and face the rapid discharge pipe, which helps to smoothly flush rust and slag on the surface of the float filter screen to the rapid discharge pipe, thereby improving the discharge effect.

[0022] Optionally, the stirring device includes a rotating shaft, a stirring frame, and a stirring drive assembly. The rotating shaft is rotatably connected to the first buffer tank in a vertical direction. The stirring frame is fixed on the rotating shaft. The side of the stirring frame away from the rotating shaft slides against the inner wall of the first buffer tank. The stirring drive assembly is installed on the outside of the first buffer tank to drive the rotating shaft to rotate.

[0023] By adopting the above technical solution, the stirring device can stir up the condensate in the first buffer tank, preventing excessive rust and slag from adhering to the inner wall of the first buffer tank, and at the same time cleaning the inner wall of the first buffer tank.

[0024] Optionally, the stirring rack includes a horizontal bar, a vertical bar, an elastic element, and a scraper. The horizontal bar is fixed to the outer peripheral wall of the rotating shaft along the radial direction of the rotating shaft. The vertical bar is fixed to the end of the horizontal bar away from the rotating shaft. One end of the elastic element is fixedly connected to the vertical bar, and the other end is fixedly connected to the scraper. The scraper slides against the inner wall of the first buffer tank.

[0025] By adopting the above technical solution, the applicability of the stirring rack is improved by using elastic elements, and the damage to the inner wall of the first buffer tank by the scraper is reduced.

[0026] Optionally, the height of the water inlet of the intermediate connecting pipe is lower than the maximum height of the stirring rack.

[0027] By adopting the above technical solution, on the one hand, the stirring rack can be used to push the condensate into the second buffer tank, reducing the inability of the condensate to flow normally due to blockage; on the other hand, it can also push some rust and slag into the second buffer tank, reducing the excessive accumulation of rust and slag in the first buffer tank, making full use of the graded discharge function of the first and second buffer tanks, and enhancing the anti-blocking function of the buffer tanks.

[0028] Optionally, the height of the first buffer container is higher than the height of the second buffer container.

[0029] By adopting the above technical solution, when the intermediate discharge valve is opened, the condensate can be forced towards the second buffer tank by the gravity of the water itself, reducing the power source and saving energy.

[0030] Optionally, an emergency drain valve is installed on the main water inlet pipe, and the emergency drain valve is electrically connected to the control module.

[0031] By adopting the above technical solution, when the buffer tank is blocked and an alarm is triggered, the staff can also directly discharge the condensate through the water inlet emergency drain valve to ensure the normal operation of the air compressor system.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The proposed solution has high monitoring accuracy and convenient control, and can promptly discharge rust and slag from the buffer tank, reducing the occurrence of buffer tank blockage and ensuring the normal operation of the supporting dryer.

[0034] 2. The stirring device can stir the condensate. If the condensate can be recycled normally through the main outlet pipe after stirring, the waste of condensate can be reduced and the recovery rate can be improved.

[0035] 3. The first and second buffer tanks work together to remove rust and slag with less water, further enhancing the recycling rate of condensate. Attached Figure Description

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0043] Example 1

[0044] This application discloses a buffer tank anti-clogging control system. (Refer to...) Figure 1 It includes a buffer tank 1, and a main water inlet pipe 2 is connected to the side wall near the top of the buffer tank 1. The water inlet end of the main water inlet pipe 2 is connected to the matching dryer, and the condensate produced by the matching dryer can flow directly into the buffer tank 1.

[0045] A liquid level sensor 3 is installed inside the buffer tank 1. A drain branch pipe 4 is connected to the bottom of the buffer tank 1. A first emergency drain valve 41 is installed near the outlet of the drain branch pipe 4. A main outlet pipe 5 is connected to the side wall of the drain branch pipe 4. An outlet valve 51 is installed on the main outlet pipe 5. The outlet end of the main outlet pipe 5 can be connected to a water collection device. The condensate collected in the buffer tank 1 can be discharged into the water collection device, which can then recycle the condensate.

[0046] The buffer tank anti-clogging control system also includes a control module (not shown in the figure), which is electrically connected to the liquid level sensor 3, the first emergency drain valve 41, and the outlet valve 51. In this embodiment, both the first emergency drain valve 41 and the outlet valve 51 are solenoid valves, and the control module can remotely control the opening and closing of the first emergency drain valve 41 and the outlet valve 51.

[0047] In this embodiment, the level sensor 3 is configured to set the outlet water level and the emergency discharge water level according to the situation. The emergency discharge water level is higher than the outlet water level, and the outlet of the main inlet pipe 2 is between the outlet water level and the emergency discharge water level. When the water level in the buffer tank 1 reaches the outlet water level, the control module controls the outlet valve 51 to open, and the condensate is transported to the water collection device through the main outlet pipe 5. The end of the main outlet pipe 5 connected to the drain branch pipe 4 is inclined upwards to reduce the possibility of rust and slag clogging the main outlet pipe 5. In addition, the buffer tank 1 can be installed at a high position in the water collection device to drain water using pressure.

[0048] During the drainage process of the main water outlet pipe 5, the liquid level sensor 3 monitors the drop in liquid level. If the liquid level in the buffer tank 1 drops slowly, does not drop, or rises within a certain period of time, it indicates that the buffer tank 1 may be blocked. At this time, the control module issues an alarm message, and the staff checks the abnormal situation and performs manual drainage and other operations.

[0049] When the water level in buffer tank 1 reaches the emergency discharge level, the control module controls the first emergency discharge valve 41 to open, using pressure to discharge condensate from the bottom of buffer tank 1, simultaneously removing any blockages at the bottom of buffer tank 1, thus resolving the problem of easy clogging in buffer tank 1. When the water level in buffer tank 1 reaches below the level sensor 3, the control module controls the first emergency discharge valve 41 to close.

[0050] In addition, an emergency drain valve 21 is installed on the main water inlet pipe 2, which is electrically connected to the control module. The emergency drain valve 21 can also be a solenoid valve. When the buffer tank 1 experiences a blockage alarm, the operator can directly drain the condensate through the emergency drain valve 21 to ensure the normal operation of the compressed air system.

[0051] The implementation principle of the buffer tank anti-clogging control system in Embodiment 1 of this application is as follows: by monitoring the liquid level of the buffer tank 1, rust and slag in the buffer tank 1 are discharged in a timely manner to reduce the occurrence of blockage in the buffer tank 1 and ensure the normal operation of the supporting dryer.

[0052] Example 2

[0053] The difference between this embodiment and Embodiment 1 lies in the structure of the buffer container 1. In this embodiment, refer to... Figure 2 The buffer tank 1 includes a first buffer tank 11 and a second buffer tank 12. The installation height of the first buffer tank 11 is higher than that of the second buffer tank 12. The first buffer tank 11 is connected to the main inlet pipe 2, and the outlet of the main inlet pipe 2 is between the outlet liquid level and the emergency discharge liquid level of the first buffer tank 11. An intermediate connecting pipe 13 connects the first buffer tank 11 and the second buffer tank 12, and the outlet of the intermediate connecting pipe 13 is located above the outlet liquid level of the second buffer tank 12. An intermediate discharge valve 14 is installed on the intermediate connecting pipe 13 and is electrically connected to the control module.

[0054] Reference Figure 2 and Figure 3 The first buffer tank 11 is equipped with a stirring device 6, which includes a rotating shaft 61, a stirring frame 62, and a stirring drive assembly 63. The rotating shaft 61 is rotatably connected to the top center of the first buffer tank 11 in a vertical direction, and the stirring frame 62 is fixed on the rotating shaft 61.

[0055] In this embodiment, the stirring rack 62 includes a horizontal bar 621, a vertical bar 622, an elastic element 623, and a scraper 624. The horizontal bar 621 is fixed radially to the outer peripheral wall of the rotating shaft 61, and multiple horizontal bars 621 are arranged axially along the rotating shaft 61. The vertical bar 622 is fixed to the end of the multiple horizontal bars 621 away from the rotating shaft 61. In this embodiment, the elastic element 623 is a spring, with one end fixedly connected to the vertical bar 622 and the other end fixedly connected to the scraper 624. The side of the scraper 624 away from the vertical bar 622 slides against the inner wall of the first buffer tank 11. During rotation, the stirring rack 62 can effectively scrape away rust and slag adhering to the inner wall of the first buffer tank 11, and at the same time stir up the rust and slag in the first buffer tank 11, thereby facilitating discharge.

[0056] The stirring drive assembly 63 is installed on the top of the first buffer tank 11. The stirring drive assembly 63 can be a belt drive device. The belt drive device is connected to the rotating shaft 61 for transmission. The belt drive device drives the rotating shaft 61 to rotate. At the same time, the belt drive device is electrically connected to the control module.

[0057] Reference Figure 2The inlet height of the intermediate connecting pipe 13 is lower than the maximum height of the stirring frame 62. On the one hand, the stirring frame 62 can be used to push the condensate into the second buffer tank 12, reducing the possibility of condensate not flowing properly due to blockage; on the other hand, it can also push some rust and slag into the second buffer tank 12, reducing the excessive accumulation of rust and slag at the bottom of the first buffer tank 11.

[0058] When the water level in the first buffer tank 11 reaches the outlet water level, the control module controls the outlet valve 51 to open. During the drainage process of the main outlet pipe 5, the level sensor 3 monitors the drop in water level. If the water level in the first buffer tank 11 drops slowly, does not drop, or rises within a certain period of time, the control module issues an alarm message. On the other hand, the control module controls the stirring device 6 to start, using the stirring device 6 to improve the efficiency of condensate drainage into the main outlet pipe 5, thereby improving the condensate recovery rate.

[0059] When the liquid level in the first buffer tank 11 reaches the emergency discharge level, the control module controls the first emergency discharge valve 41 to open, allowing the condensate at the bottom of the first buffer tank 11 to be discharged through the drain pipe 4. Simultaneously, the control module controls the intermediate discharge valve 14 to open, allowing some condensate to flow into the second buffer tank 12 through the intermediate connecting pipe 13. The second buffer tank 12 then buffers and discharges the condensate, ensuring the continuous operation of the compressed air system. When the water level in the first buffer tank 11 reaches below the level sensor 3, the control module controls the first emergency discharge valve 41 and the intermediate connecting pipe 13 to close.

[0060] Reference Figure 2 A float filter screen 7 is installed inside the second buffer tank 12, located below the outlet of the intermediate connecting pipe 13. The float filter screen 7 includes a filter screen and a float installed at the bottom of the filter screen. The filter screen traps rust and debris on its surface. When the water level in the second buffer tank 12 rises, the float moves the filter screen upwards, making the condensate at the bottom of the second buffer tank 12 cleaner. Simultaneously, the main outlet pipe 5 is connected to the bottom of the second buffer tank 12. When the outlet valve 51 corresponding to the second buffer tank 12 is opened, the condensate at the bottom of the second buffer tank 12 can be discharged into the main outlet pipe 5.

[0061] The second buffer tank 12 has an emergency drain pipe 15 connected to its side wall away from the intermediate connecting pipe 13. A second emergency drain valve 16 is installed on the emergency drain pipe 15 and is electrically connected to the control module. The height of the emergency drain pipe 15 is lower than that of the intermediate connecting pipe 13. A limiting block 71 for limiting the floating height of the float filter screen 7 is installed on the side wall of the second buffer tank 12 near the outlet of the intermediate connecting pipe 13. Multiple limiting blocks 71 are provided, and the height of the limiting block 71 near the intermediate connecting pipe 13 is higher than that of the limiting block 71 near the emergency drain pipe 15.

[0062] Reference Figure 4 When the liquid level rises, it causes the float filter screen 7 to rise. The float filter screen 7 has a groove pre-cut for the liquid level sensor 3 to pass through. When the upper surface of the float filter screen 7 abuts against the limiting block 71, under the action of the limiting block 71, the float filter screen 7 tilts downward and faces the rapid discharge pipe 15. When the level sensor 3 of the second buffer tank 12 detects that the liquid level is consistent with the height of the highest limit block 71, the control module controls the second emergency discharge valve 16 to open. Water flows over the upper surface of the float filter screen 7, flushing rust and debris onto it into the emergency discharge pipe 15, from which the rust and debris are discharged. During the discharge process, the float filter screen 7 remains tilted downwards. At this time, the water flow rate of the intermediate connecting pipe 13 is greater than that of the emergency discharge pipe 15, causing the water level to continue rising. After a period of discharge, the second emergency discharge valve 16 closes, and the water level rises to the outlet level of the second buffer tank 12. The corresponding outlet valve 51 of the second buffer tank 12 opens, recovering clean condensate and reducing the likelihood of blockage in the second buffer tank 12. When the water level in the second buffer tank 12 reaches below the level sensor 3, the control module controls the outlet valve 51 to close.

[0063] Compared with Example 1, the advantage of this embodiment is that it can use less water to remove more rust and slag, thereby improving the recovery rate of condensate.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
