Description

Technical Field

[0001] This utility model belongs to the technical field of compressed air drainers, specifically, it relates to a zero-air-consumption drainer. Background Technology

[0002] With the development of low-carbon energy, the application of compressed air is becoming increasingly widespread in both industrial and civilian life. Compressed air is a clean power source based on the compressibility of air. It is produced by an air compressor, which reduces the volume of the compressed air and increases its pressure. Compared with other energy sources, it has advantages such as low cost of air raw materials, stable performance, and applicability in many adverse environments.

[0003] However, due to the nature of its production, compressed air often contains moisture and oil vapors. Furthermore, because the pipelines used for storage and transportation are frequently used, corrosion occurs, often resulting in the presence of impurities such as rust. Therefore, during the transportation or storage of compressed air, drainers are needed to remove as much moisture, oil vapors, and other impurities (oil sludge-rust mixture) as possible. However, currently used drainers often cannot effectively control the liquid level or perform the corresponding drainage operations, leading not only to poor drainage and sewage removal efficiency but also to the problem of directly releasing compressed air into the atmosphere, resulting in a meaningless waste of energy.

[0004] Therefore, there is an urgent need to provide a zero-air-consumption drainer that has better drainage and sewage discharge effects and does not incorrectly discharge compressed air, in order to overcome the above problems.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0045] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship 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.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] like Figure 1 As shown, the zero-air-consumption drainer of this utility model is applied to compressed air production equipment and / or buffer equipment. The zero-air-consumption drainer includes:

[0048] Storage tank 1, wherein the storage tank 1 is configured to hold the oil sludge-rust mixture discharged from the production equipment and / or buffer equipment of the compressed air;

[0049] Liquid inlet pipe 2, one end of which is connected to the drain port of the compressed air production equipment and / or buffer equipment, and the other end of which is connected to the liquid inlet 11 of the storage tank 1;

[0050] The liquid outlet pipe 3 has one end connected to the liquid outlet 12 of the storage tank 1, and the other end connected to the outside.

[0051] Solenoid valve 4, configured to control the opening or closing of the liquid outlet pipe 3, is disposed on the liquid outlet pipe 3;

[0052] A float-type liquid level switch 5, wherein the liquid level detection part of the float-type liquid level switch 5 is vertically suspended inside the storage tank 1;

[0053] Control unit 6 controls the solenoid valve 4 to switch between open and closed states based on the electrical signal sent by the float-type liquid level switch 5.

[0054] In this invention, the float-type liquid level switch 5 is used to reflect the volume of the oil sludge-rust mixture accumulated in the storage tank 1. The change in liquid level is used to control the solenoid valve 4 to open or close, thereby achieving automatic control of drainage and sewage discharge, resulting in better sewage discharge effect. When the volume of the mixture in the storage tank 1 is within a certain standard, the solenoid valve 4 closes, preventing the compressed air in the upstream equipment from being mistakenly discharged.

[0055] Understandably, in existing technologies, gas storage tanks often contain residual liquid and impurities, which makes existing types of drainers prone to clogging, increasing replacement costs. Furthermore, once clogged, the drainer doesn't completely seal off immediately, making the actual degree of blockage difficult to detect. This leads to reduced drainage capacity, with the amount of water and impurities stored in the tank increasing, significantly reducing the actual capacity of the gas storage tank. The design provided in this application transfers the water-gas separation component from the original gas storage tank to this zero-gas-consumption drainer. There are no residual liquids or impurities in the gas storage tank, ensuring that its actual capacity remains optimal. Simultaneously, the zero-gas-consumption drainer eliminates the clogging problem.

[0056] In one specific embodiment of this example, the compressed air production equipment includes centrifuges, screw compressors, dryers, refrigerated dryers, precoolers, and other equipment used in the compressed air production process.

[0057] The compressed air buffer device includes equipment such as air tanks and pipelines used in the compressed air storage and transportation process.

[0058] In one specific embodiment of this example, the sludge-rust mixture is a mixture comprising one or more impurities such as condensate, oil-water mixture, rust residue, and particulate matter.

[0059] In one specific embodiment of this example, a manual control valve (not shown in the figure) is provided on the inlet pipe 2, which can control the connection or disconnection between the inlet pipe 2 and the storage tank 1;

[0060] The manual control valve is open during normal equipment operation and closed during equipment maintenance or repair.

[0061] Please see the appendix Figure 1 In one specific embodiment of this example, the liquid outlet pipe 3 includes: a first pipe section 31 and a second pipe section 32 that are perpendicular to each other and smoothly connected, wherein the first pipe section 31 is vertically arranged and the second pipe section 32 is horizontally arranged.

[0062] The end of the first pipe section 31 that is away from the second pipe section 32 is connected to the liquid outlet 12;

[0063] The end of the second pipe section 32 away from the first pipe section 31 is connected to the outside; the solenoid valve 4 is provided on the second pipe section 32.

[0064] In one specific embodiment of this example, the liquid outlet pipe 3 further includes a third pipe section (not shown in the figure), the third pipe section is arranged parallel to the second pipe section 32, one end of the third pipe section is connected to and communicates with the first pipe section 31, and the end of the third pipe section away from the first pipe 31 is connected to the outside.

[0065] An emergency manual valve is installed on the third pipe section.

[0066] The third pipe section can be used in an emergency when the solenoid valve 4 on the second pipe section 32 malfunctions.

[0067] In this invention, by setting the first pipe section 31 and the second pipe section 32 with the smooth transition connection, the problem of the mixture accumulating at the pipe corner during the sewage discharge stage (the stage of discharging the oil sludge-rust mixture) causing blockage of the liquid outlet pipe 3 and the valve core of the solenoid valve 4 can be effectively avoided.

[0068] In one specific embodiment of this example, the first pipe section 31 is connected to the liquid outlet 12. This can be achieved by welding the two together, or by adding a connecting flange (adding a connecting component) on the adjacent side of the two. The connection forms of other components, such as pipes to pipes and pipes to pipes and pipes to pipes, are similar and will not be described in detail here.

[0069] In one specific embodiment of this example, the diameters of the first pipe section 31 and the second pipe section 32 are equal.

[0070] The axis of the first pipe segment 31 is perpendicular to the axis of the second pipe segment 32.

[0071] Please see the appendix Figure 1 In one specific embodiment of this example, the storage tank 1 further includes: a liquid injection pipe 13, which is disposed inside the storage tank 1;

[0072] One end of the injection pipe 13 is connected to the side of the inlet 11 away from the inlet pipe 2, and the other end of the injection pipe 13 extends toward the bottom of the storage tank 1.

[0073] In this invention, by setting the injection pipe 13, a path guide is provided for the oil sludge-rust mixture injected into the storage tank 1, which facilitates its smooth and correct discharge.

[0074] In one specific embodiment of this example, the injection pipe 13 has an angle relative to the vertical portion of the float-type liquid level switch 5, and the distance between the injection pipe 13 and the float-type liquid level switch 5 gradually increases along the horizontal cross-section near the bottom of the tank.

[0075] In this invention, the design of the injection pipe 13 being tilted away from the float-type liquid level switch 5 can effectively prevent the oil sludge-rust mixture from directly impacting the float-type liquid level switch 5, thus ensuring its service life and functional stability.

[0076] In one specific embodiment of this invention, the diameter of the injection pipe 13 is smaller than the diameter of the inlet pipe 2. According to the Venturi effect, reducing the diameter of the closed pipe can increase the flow rate and reduce the local pressure at the inlet 11, which has a positive effect on achieving rapid injection and ensuring the cleanliness and reliability of the inlet 11.

[0077] Please see the appendix Figure 1 In one specific embodiment of this example, the storage tank 1 further includes a drain pipe 14, which is disposed inside the storage tank 1.

[0078] One end of the drain pipe 14 is connected to the side of the outlet 12 away from the outlet pipe 3, and the other end of the drain pipe 14 is connected to extend toward the bottom of the storage tank 1.

[0079] The distance between the drain pipe 14 and the bottom of the tank is less than the distance between the injection pipe 13 and the bottom of the tank.

[0080] In this invention, by setting the drain pipe 14, the oil sludge-rust mixture accumulated in the storage tank 1 is discharged from bottom to top, thereby achieving the effect of preferentially discharging solid sediments.

[0081] In one specific embodiment of this example, the diameter of the drain pipe 14 is larger than the diameter of the outlet pipe 3. According to the Venturi effect, reducing the diameter of the closed pipe can increase the flow rate and reduce the local pressure at the outlet 12, which has a positive effect on achieving rapid drainage and ensuring the cleanliness and reliability of the outlet 12.

[0082] Please see the appendix Figure 1 In one specific embodiment of this example, the storage tank 1 further includes: a vent 15, which is located on the side away from the bottom of the storage tank 1;

[0083] Ventilation pipe 16, one end of which is connected to the ventilation port 15, and the other end of which is connected to the outside, or the other end of which is connected to a ventilation buffer device (not shown in the figure).

[0084] In this invention, by setting the vent 15 and vent pipe 16, the problem of pressure imbalance in the storage tank 1 is avoided, and the accumulation of mixture in the storage tank 1 through the injection pipe 13 and the discharge of mixture from the storage tank 1 to the outside through the drain pipe 14 are ensured.

[0085] In one specific embodiment of this example, the opening of the ventilation pipe 16 is adjustable, for example, by providing an adjusting valve on the ventilation pipe 16.

[0086] In one specific embodiment of this invention, a one-way valve (not shown in the figure) is provided on the ventilation pipe 16.

[0087] In one specific embodiment of this application, the ventilation buffer device (not shown in the figure) is a hollow cylindrical structure. The ventilation buffer device is provided with a first port and a second port. The first port and the second port are located at different horizontal heights. The first port is connected to the ventilation pipe 16, and the second port is connected to the outside.

[0088] Compared to the scheme where the ventilation pipe 16 is directly connected to the outside, setting up a ventilation buffer device is equivalent to adding a section with a larger diameter to the ventilation pipe 16, which makes the gas flow smoother and more stable.

[0089] Please see the appendix Figure 1 In one specific embodiment of this invention, the float-type liquid level switch 5 includes:

[0090] A float, wherein a magnet block is disposed inside the float;

[0091] The connecting rod 51 has the float sleeved on it; the connecting rod 51 has an internal receiving cavity.

[0092] A magnetic switching element (e.g., a reed switch) is disposed within a receiving cavity inside the connecting rod 51;

[0093] When the float approaches the magnetic switching element, the magnet in the float will cause the contacts of the magnetic switching element to close or open, thereby generating an electrical signal that reflects the switching information.

[0094] In one specific embodiment of this example, the connecting rod 51 is further provided with a signal transmission line for transmitting the electrical signal generated by the magnetic switching element to the control unit 6 (the magnetic switching element is electrically connected to the control unit 6).

[0095] The control unit 6 controls the solenoid valve 4 to switch between open and closed states (start or stop state) based on the received electrical signal.

[0096] Please see the appendix Figure 1 In one specific embodiment of this example, the connecting rod 51 is provided with a first identification position 52 and a second identification position 53; along the axial direction of the connecting rod 51, the first identification position 52 and the second identification position 53 are arranged in sequence toward the bottom of the storage tank 1.

[0097] The connecting rod 51 corresponds to the positions of the second identification position 53 and the first identification position 52, and has a receiving cavity inside it. The magnetic switching element is disposed in the receiving cavity. When the float moves to the position of the first identification position 52, and / or when the float moves to the position of the second identification position 53, the magnetic switching element will have its contacts closed or opened under the attraction of the magnet block in the float, thereby generating an electrical signal reflecting the switching information.

[0098] That is: when the float is in the second identification position 53, it sends a second electrical signal and the solenoid valve 4 is in the off state; when the float is in the first identification position 52, it sends a first signal and the solenoid valve 4 is in the on state.

[0099] More specifically, in the initial state (no mixture or very little mixture in storage tank 1), the float is in the second identification position 53, and the solenoid valve is closed;

[0100] As the mixture accumulated in the storage tank 1 increases, the float moves from the second identification position 53 toward the direction closer to the first identification position 52 under the action of buoyancy, during which the solenoid valve 4 remains in the closed state.

[0101] When the float moves to the first identification position 52 under the action of buoyancy, it sends a first electrical signal, the solenoid valve switches state, the solenoid valve is turned on, and the oil sludge-rust mixture accumulated in the storage tank 1 is discharged through the drain pipe 14 and the outlet pipe 3.

[0102] As the float continues to move away from the bottom of the tank, the solenoid valve 4 remains in the on state as the float moves from the first identification position 52 toward the second identification position 53.

[0103] When the float is located at the second identification position 53, a second electrical signal is sent, and the solenoid valve 4 switches to the off state.

[0104] By applying the zero-air-consumption drainer provided in this application, the mixture can be automatically discharged in this way. When the mixture contained in it is lower than the horizontal height of the second identification position 53, the outlet pipe 3 is cut off from the outside in time to prevent abnormal discharge of compressed air from the connected equipment (compressed air production or buffer equipment).

[0105] In one specific embodiment of this invention, the magnetic switch element includes: a first magnetic switch and a second magnetic switch, wherein the first magnetic switch is disposed in the receiving cavity of the connecting rod 51 corresponding to the position of the first identification position 52; and the second magnetic switch is disposed in the receiving cavity of the connecting rod 51 corresponding to the second identification position 53.

[0106] In one specific embodiment of this example, the height of the horizontal plane at the extended end of the injection tube 13 (the end of the injection tube 13 near the bottom of the tank) is higher than the height of the horizontal plane at the first identification position 52 along the vertical direction.

[0107] In one specific embodiment of this example, the height of the horizontal plane at the extended end of the drain pipe 14 (the end of the drain pipe 14 near the bottom of the storage tank 1) perpendicular to the vertical direction is less than the height of the horizontal plane at the second identification position 53.

[0108] In one specific embodiment of this example, the connecting rod 51 is provided with a stop plate (not shown in the figure) at its extended end near the bottom of the tank. The stop plate defines the maximum position at which the float can move towards the bottom (towards the bottom of the tank) (the float abuts against the stop plate).

[0109] The stop plate is positioned on the connecting rod 51 at the location corresponding to the second identification position 53.

[0110] In one specific embodiment of this example, the control unit 6 further includes a timing module (not shown in the figure), which is used to record the actual time taken for the float to travel from the first identification position 52 to the second identification position 53, and to record the actual time taken from the second identification position 53 to the first identification position 52.

[0111] In one specific embodiment of this example, in the initial state (when the storage tank 1 is relatively empty), the float abuts against the upper side of the stop plate (the side of the stop plate near the first identification position 52).

[0112] In one specific embodiment of this example, in the initial state (the float is in the second identification position 53), the solenoid valve 4 is in the closed state and the liquid outlet pipe 3 is closed;

[0113] When the float is in the first identification position 52, the solenoid valve 4 is in the conducting state;

[0114] When the float moves from the second identification position 53 to the first identification position 52, the solenoid valve 4 changes from the closed state to the open state; the oil sludge-rust mixture in the storage tank 1 is discharged through the drain pipe 14 and the outlet pipe 3;

[0115] The zero-gas-consumption drainer provided by this utility model uses the positive pressure formed by the gas and liquid stored in the storage tank 1 to discharge the condensate mixed with the oil sludge-rust mixture in the storage tank 1 from the drain pipe 14 and the outlet pipe 3.

[0116] When the float moves from the first identification position 52 to the second identification position 53, the solenoid valve switches from the on state to the off state.

[0117] Please see the appendix Figure 1 In one specific embodiment of this example, the zero-gas-consumption drainer further includes a bracket, which is fixed to the outer wall of the storage tank 1.

[0118] The control unit 6 is mounted on the storage tank 1 via the bracket.

[0119] In this invention, by setting the bracket, the control unit 6 can be firmly connected to the storage tank 1, resulting in a higher overall integration of the equipment and a positive effect on reducing the floor space occupied.

[0120] In one specific embodiment of this example, when the float is in the second identification position 53 under the action of gravity, the float-type liquid level switch 5 sends a first electrical signal;

[0121] When the float moves to the first identification position 52 or above under the action of buoyancy, the float-type liquid level switch 5 sends a second electrical signal.

[0122] In the initial state, the solenoid valve 4 is in the closed state. When the control unit 6 receives the first electrical signal, it controls the solenoid valve 4 to switch to the open state, and the liquid outlet pipe 3 is opened.

[0123] When the control unit 6 receives the second electrical signal, it controls the solenoid valve 4 to switch to the off state, and the liquid outlet pipe 3 is cut off.

[0124] In one specific embodiment of this example, the control unit 6 includes a first indicator light and a second indicator light. When the control unit 6 receives an electrical signal from the float-type liquid level switch 5 that is a first electrical signal, the first indicator light illuminates; when the control unit 6 receives an electrical signal from the float-type liquid level switch 5 that is a second electrical signal, the second indicator light illuminates.

[0125] To further clarify the explanation, the control logic of some functions (automatic sewage discharge) between the float-type liquid level switch 5 and the control unit 6 will be explained below. However, it should be made clear that this judgment logic is only one feasible application scheme, not the only one. In addition, this principle explanation is only for the clarity of the scheme and is not a limiting feature of the structural scheme.

[0126] Specifically:

[0127] Parameters determined:

[0128] A1, the first liquid level of the sludge-rust mixture, corresponding to the position of the second identification position 53; A2, the second liquid level of the sludge-rust mixture, corresponding to the position of the first identification position 52;

[0129] T1, the first storage time of tank 1, is the actual time taken for the float to move from A1 to A2; T2, the second storage time of tank 2, is the actual time taken for the float to move from A2 to A1.

[0130] T10, the first set time for the storage tank, the theoretical time for the float to move from A1 to A2; T20, the second set time for the storage tank, the theoretical time for the float to move from A2 to A1;

[0131] T1 and T2 are recorded by the timing module; T10 and T20 are pre-stored in the control unit 6.

[0132] When T1 > T10, the control unit 6 calculates the ratio T1 / T10 by performing data calculation on T1 and T10; by calculating the ratio T1 / T10, it determines whether the connected equipment body is stopped, whether the built-in drain port is blocked, whether the float switch is faulty, and generates and sends corresponding warning information.

[0133] More specifically:

[0134] When the calculated ratio T1 / T10 > 1.5 and the float position remains unchanged at position A2, it indicates that the connected equipment has stopped working.

[0135] When the calculated ratio T1 / T10 > 1.5 and the float position is higher than position A2, the control unit 6 issues a command to control the solenoid valve 4 to open; after the solenoid valve 4 is opened, if the float position falls back to position A2, it indicates that the drain port of the connected equipment is blocked; if the float position does not fall back to position A2, it indicates that the float switch is faulty and needs to be repaired and a corresponding warning message should be sent.

[0136] When T2 is greater than T20, the control unit 6 calculates the ratio T2 / T20 by combining T2 and T20. The ratio T2 / T20 is used to determine whether the connected device has serious internal leakage or whether the float switch is faulty, and corresponding warning information is generated.

[0137] When the calculated ratio T2 / △T20>1.5 and the float position remains unchanged at position A1, it indicates that the float switch is faulty and needs to be repaired and a corresponding warning message should be sent.

[0138] When the calculated ratio T2 / T20>2 and the float position is between A1 and A2, it indicates that there is an internal leakage fault in the compressed air production equipment, which leads to a significant increase in the water content in the compressed air. This causes the solenoid valve 4 to work continuously. For example, if the dryer is shut down in winter and the circulating water in the dryer cooler is not completely drained at sub-zero temperatures, the cooler pipes may freeze and crack. When the equipment is restarted or the temperature rises and the pipes thaw, a large amount of circulating water leaking from the frozen and cracked cooler pipes will be discharged through the zero-air-consumption drain device with automatic drainage function.

[0139] The system will issue warnings and push notifications to promptly notify personnel to handle the situation, thereby reducing equipment damage and substandard compressed air quality caused by internal leaks.

[0140] In one specific embodiment of this example, the control unit 6 further includes a wireless communication module, which is communicatively connected to a smart receiving device (such as a mobile phone, computer, tablet, or other device with receiving function).

[0141] When the control unit 6 receives the electrical signal sent by the float-type liquid level switch 5, it sends the liquid level information reflected by the type of electrical signal (first electrical signal and / or second electrical signal) and the corresponding control action made by the control unit 6 to the intelligent receiving device.

[0142] In one specific implementation of this embodiment, the aforementioned warning information is sent to the smart mobile device via the wireless communication module.

[0143] In another specific embodiment of this example, the solenoid valve 4 can also be opened at regular intervals to discharge, for example, it can be opened automatically at 12:00 noon every day to discharge.

[0144] Please see the appendix Figure 1 In one specific embodiment of this invention, the zero-gas-consumption drainer further includes:

[0145] Support columns 7 are configured to support the storage tank 1 on the ground; multiple support columns 7 are provided.

[0146] The base 8 is a cuboid structure and is located at the end of the support column 7 facing closer to the ground. In the vertical direction, the projected area of ​​the base 8 is larger than the projected area of ​​the support column 7.

[0147] In one specific embodiment of this example, a triangular reinforcing rib (not shown in the figure) is also provided between the support column 7 and the base 8.

[0148] In one specific embodiment of this practice, the support column 7 is a structural member with an adjustable length in the vertical direction that serves as a support.
