Description

A timed automatic drainage device Technical Field

[0001] This utility model relates to the field of compressed air systems, and in particular to a timed automatic drainage device. Background Technology

[0002] In industrial production, compressed air systems are widely used in various production equipment and processes. During the generation of compressed air, the air temperature rises after compression, and a large amount of condensate is produced when the temperature drops. This condensate accumulates at the bottom of the air storage container, and if it is not removed in time, it will cause various adverse effects on the compressed air system and related equipment.

[0003] First, the condensate that accumulates in the gas storage container usually contains oil and impurities. These substances are corrosive to metal materials, and their long-term presence can lead to a reduction in the thickness of the gas storage container wall, thereby shortening the service life of the equipment and increasing the cost of equipment maintenance and replacement.

[0004] Secondly, condensate can enter downstream pipes and equipment along with compressed air, washing away lubricating oil, accelerating component wear, and even causing equipment jamming and failure, thus affecting the normal operation of pneumatic equipment. In precision manufacturing and automated production lines, pneumatic equipment failure can lead to the shutdown of the entire production line, causing significant economic losses.

[0005] Furthermore, condensation reduces the quality of compressed air, affecting production processes and product quality. In industries with high requirements for compressed air purity, such as spraying, food packaging, and pharmaceutical production, moisture contamination can directly impact product quality, leading to product scrapping or rework.

[0006] Traditional drainage methods mainly include manual drainage and float-type automatic drainage. Manual drainage requires a designated person to periodically open the drain valve to remove condensate. This method is not only labor-intensive but also prone to delays, often resulting in forgotten drainage or incomplete drainage. Especially in situations with insufficient staff or complex working environments, manual drainage is even less reliable.

[0007] While float-type automatic drainage requires no manual intervention, its complex structure makes it susceptible to malfunction due to impurities in condensate. The float mechanism is prone to accumulating oil and impurities, preventing it from floating properly and rendering the drainage function ineffective. Furthermore, float-type drainage devices have strict requirements regarding installation location and angle, and are relatively difficult to maintain and clean.

[0008] Existing timed drainage devices mostly use fixed time intervals for drainage, which cannot adjust the drainage frequency and duration according to actual operating conditions. The drainage effect varies greatly under different seasons and environmental humidity conditions. Some drain too frequently, resulting in wasted compressed air; others drain insufficiently, failing to effectively remove condensate.

[0009] In addition, existing drainage devices are mostly large in size, making them difficult to install in space-constrained locations, which leads to the use of inconvenient manual drainage methods. Summary of the Invention

[0010] The purpose of this invention is to provide a timed automatic drainage device that can automatically drain condensate from compressed air storage containers at regular intervals without manual operation, thereby improving drainage efficiency and reliability.

[0011] To solve the above-mentioned technical problems, this utility model provides a timed automatic drainage device, including an air storage container for storing compressed air;

[0012] A timed electromagnetic drainage assembly is installed at the bottom of the gas storage container. The timed electromagnetic drainage assembly includes a timer controller and an electromagnetic drainage valve. The electromagnetic drainage valve is connected to the bottom of the gas storage container and is also electrically connected to the timer controller, and is used to open and close the valve at regular intervals according to the control signal of the timer controller.

[0013] Furthermore, the gas storage container is equipped with a safety valve at the top, a compressed air outlet at the upper part of one side, and a compressed air inlet at the lower part of the other side.

[0014] Furthermore, the timing controller is equipped with two rotary adjustment knobs, one for setting the drainage duration and the other for setting the drainage interval.

[0015] Furthermore, the adjustment range of the drainage duration setting knob is 0.5 to 10 seconds.

[0016] Furthermore, the adjustment range of the drainage interval setting knob is 0.5 to 45 minutes.

[0017] Furthermore, the timer controller is equipped with a test button, and start indicator lights and stop indicator lights are provided on both sides of the test button.

[0018] Furthermore, the electromagnetic drain valve includes a pipe, a ball valve, and an intermediate connection port. The ball valve is located on one side of the pipe. One end of the pipe is a water inlet threaded interface, and the other end is a drain outlet. The intermediate connection port is located on the other side of the pipe and is close to the drain outlet.

[0019] Furthermore, the timing controller has a connection interface at its bottom, and the middle connection port is connected to the connection interface of the timing controller.

[0020] Furthermore, it also includes a pressure gauge, which is mounted on the gas storage container.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] The timed automatic drainage device proposed in this invention uses a bottom-mounted timed electromagnetic drainage component to automatically open the drainage valve at preset time intervals, ensuring timely discharge of condensate.

Furthermore, it requires no manual intervention, significantly improving drainage efficiency and reliability. The device also features a simple structure, convenient installation, and suitability for various industrial environments. Attached Figure Description

[0027] Based on the teachings of this specification, those skilled in the art can form new technical solutions by combining different implementation methods without creating technical contradictions. Such variations should be considered to fall within the protection scope of this patent.

[0028] The following is a more detailed description of a timed automatic drainage device according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0029] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0030] As shown in Figures 1 to 3, this utility model embodiment proposes a timed automatic drainage device, including a gas storage container 1 and a timed electromagnetic drainage component.

[0031] Specifically, the air storage container 1 is used to store compressed air and acts as a buffer in the compressed air system. When the compressor experiences a brief shortage of air supply or the air-consuming equipment suddenly increases its air consumption, the compressed air in the air storage container 1 can be quickly replenished, preventing the production equipment from shutting down or operating unstablely due to insufficient air pressure. The timed electromagnetic drainage component is installed at the bottom of the air storage container 1 to realize the timed automatic discharge of condensate in the air storage container 1, ensuring the cleanliness and quality of the compressed air and preventing condensate from having an adverse effect on the system.

[0032] In this embodiment, the timed electromagnetic drainage assembly includes a timer controller 5 and an electromagnetic drainage valve 9. The electromagnetic drainage valve 9 is connected to the bottom of the gas storage container 1. The timer controller 5, as the core control component of the entire drainage device, sends control signals to the electromagnetic drainage valve 9 according to set time parameters, precisely controlling the opening and closing times of drainage to achieve a timed automatic drainage function. The electromagnetic drainage valve 9 is also electrically connected to the timer controller 5 and is used to open and close at regular intervals according to the control signals from the timer controller 5. Upon receiving the signal from the timer controller 5, the electromagnetic drainage valve 9 quickly opens or closes, allowing for timely drainage and preventing condensate from accumulating in the gas storage container 1 for an extended period.

[0033] The timed electromagnetic drainage component, through the timer controller 5, flexibly adjusts the drainage time interval and duration according to different usage environments and production process requirements, thereby improving the timeliness and effectiveness of drainage. For example, in humid areas or high-pressure, low-temperature environments, the drainage interval can be appropriately shortened to accommodate situations where condensate is generated quickly; when the gas storage container 1 has a large volume, although the total amount of condensate generated is large, the accumulation rate of condensate is relatively slow due to the large space, thus allowing for an appropriate extension of the drainage interval.

[0034] In this embodiment, the gas storage container 1 is equipped with a safety valve at the top, a compressed air outlet 3 on the upper part of one side, and a compressed air inlet 2 on the lower part of the other side. The safety valve automatically opens when the pressure inside the gas storage container 1 exceeds a set safety threshold, releasing excess pressure and preventing the gas storage container 1 from exploding or experiencing other safety accidents due to excessive pressure. The compressed air inlet 2 introduces compressed air generated by the compressor into the gas storage container 1 for storage and buffering. Located at the lower part of the other side of the gas storage container 1, the compressed air inlet 2 reduces the impact of compressed air entering the gas storage container 1, minimizing its impact on the internal structure and extending the service life of the gas storage container 1. The compressed air outlet 3 delivers the compressed air from the gas storage container 1 to the gas-using equipment, ensuring that the equipment receives stable and clean compressed air. Located at the upper part of one side of the gas storage container 1, the compressed air output undergoes sufficient sedimentation, reducing the output of condensate and impurities and improving the quality of the output gas.

[0035] In this embodiment, the timing controller 5 has two rotary adjustment knobs: one for setting the drainage duration (6) and the other for setting the drainage interval (7). The drainage duration setting knob 6 is used to set the duration of each drainage process, i.e., the length of time the electromagnetic drain valve 9 is open. A reasonable drainage duration can prevent the pressure inside the air storage container 1 from dropping too quickly due to excessive drainage time, thereby avoiding unnecessary pressure shocks to the compressor and air-using equipment and extending the service life of the equipment. The drainage interval setting knob 7 is used to set the interval between two drainages, i.e., the time from when the electromagnetic drain valve 9 closes to when it opens again. A reasonable drainage interval can ensure relatively stable pressure inside the air storage container 1, avoiding pressure fluctuations caused by frequent drainage, preventing compressed air leakage or frequent start-stop of the electromagnetic drain valve 9 due to an unreasonable drainage interval setting, reducing system energy consumption, and improving the operational stability of the entire compressed air system. The design of the two rotary adjustment knobs provides users with high flexibility, allowing them to flexibly adjust the drainage duration and drainage interval according to different usage environments and production process requirements, ensuring that the drainage device operates efficiently under various operating conditions.

[0036] Furthermore, the adjustment range of the drainage duration setting knob 6 is 0.5 to 10 seconds, which can precisely control the duration of each drainage process, so that the drainage operation can effectively remove condensate water without causing unnecessary energy waste or system pressure fluctuations due to excessive time.

[0037] The 0.5-second drainage time is suitable for applications where the amount of condensate generated is small or where the drainage speed requirement is extremely high, such as in small air storage containers or dry environments. Short drainage time can meet the needs while avoiding a drop in compressed air pressure due to excessive drainage time.

[0038] A 10-second drainage time is suitable for situations where a large amount of condensate is generated or drainage is difficult, such as in humid, high-pressure, low-temperature environments or large gas storage containers. A longer drainage time can ensure that the condensate is completely drained and prevent condensate from accumulating.

[0039] The 0.5 to 10-second adjustment range covers the needs of most industrial applications, allowing users to adjust flexibly according to actual working conditions without replacing equipment or making complex settings, thus improving the versatility and adaptability of the device.

[0040] Furthermore, the adjustment range of the drainage interval setting knob 7 is 0.5 to 45 minutes, which can precisely control the time interval between two drainage operations, ensuring that condensate can be discharged in a timely manner, while avoiding too little or too much condensate accumulation due to too short or too long drainage intervals.

[0041] A 0.5-minute (30-second) drainage interval is suitable for environments where condensate is generated very quickly, such as industrial environments with high humidity, high pressure, and low temperature. In such environments, condensate may accumulate in large quantities in a short period of time, requiring frequent drainage to prevent the condensate from causing adverse effects on the system.

[0042] A 45-minute drainage interval is suitable for environments where condensate is generated slowly, such as in dry areas or small gas storage containers 1, where the amount of condensate generated is small. A longer drainage interval can reduce unnecessary drainage operations and reduce energy consumption.

[0043] The 0.5 to 45 minute adjustment range covers various operating conditions, from high humidity, high pressure and low temperature environments to dry and low flow environments. Users can flexibly adjust the drainage interval according to actual needs without replacing equipment or making complicated settings.

[0044] In practical implementation, the timed automatic drainage device can flexibly adapt to various industrial scenarios and environmental conditions by adjusting the drainage duration (0.5–10 seconds) and drainage interval (0.5–45 minutes). For example, in small gas storage containers 1 or dry environments, the drainage duration can be set to 0.5 seconds and the drainage interval to 10 minutes to cope with the generation of small amounts of condensate and reduce energy consumption. In humid southern coastal areas or high-pressure, low-temperature chemical plants, where condensate is generated quickly, the drainage duration can be adjusted to 5 seconds or even 8 seconds, and the drainage interval can be shortened to 2 minutes or 5 minutes to ensure timely drainage of condensate and prevent equipment corrosion and system pressure fluctuations. For large gas storage containers 1 or high-flow-rate gas environments, such as gas tanks of 5 cubic meters or more or automobile manufacturing production lines, the drainage duration can be set to 6 to 10 seconds and the drainage interval to 15 to 20 minutes to balance drainage demand and system stability. In high-precision manufacturing processes, such as electronic chip manufacturing, to ensure the high dryness of compressed air, the drainage time can be set to 2 seconds, with a drainage interval of 1 minute. Frequent drainage avoids condensation affecting product quality. This flexible adjustment method enables the drainage device to operate efficiently and stably, reducing energy consumption and equipment wear, extending equipment lifespan, and meeting the needs of different industrial scenarios.

[0045] In this embodiment, the timer controller 5 is equipped with a test button 8, with start and stop indicator lights on either side of the test button 8. The test button 8 is used to manually trigger the drainage operation, allowing for quick checks of the drainage device's functionality during installation, debugging, or routine maintenance. This enables timely detection of potential faults, preventing condensate buildup due to equipment malfunctions and ensuring reliable device operation. The start and stop indicator lights respectively indicate the operating status of the drainage device, allowing users to intuitively understand whether the drainage device is in operation. When the start indicator light is on, it indicates that the drainage device has started and the electromagnetic drain valve 9 is opening; when the stop indicator light is on, it indicates that the drainage device has stopped operating and the electromagnetic drain valve 9 is closed. The indicator light status allows users to monitor the drainage device's operation in real time. Users can quickly understand the drainage device's operating status through simple button operation and intuitive indicator light displays, eliminating the need for complex tools or equipment, thus reducing operational difficulty and maintenance costs.

[0046] In this embodiment, the electromagnetic drain valve 9 includes a pipe, a ball valve 10, and an intermediate connection port 11. The ball valve 10 is located on one side of the pipe, with one end of the pipe being a water inlet threaded interface and the other end being a drain port 12. The intermediate connection port 11 is located on the other side of the pipe, close to the drain port 12. The ball valve 10 is typically made of stainless steel or other corrosion-resistant materials, capable of adapting to humid and corrosive environments, and is opened and closed by rotating a ball, exhibiting good sealing performance and rapid response capability. The drain port 12 is used to discharge condensate from the system, connecting to an external drainage pipe or ditch to prevent accumulation.

[0047] In this embodiment, the timing controller 5 is provided with a connection interface at the bottom, and the middle connection port 11 is connected to the connection interface of the timing controller 5, which can realize precise control of the electromagnetic drain valve 9, so that the drainage operation can be executed accurately according to the preset time interval and duration, thereby improving the operating efficiency of the system.

[0048] In this embodiment, the timed automatic drainage device further includes a pressure gauge 4, which is mounted on the gas storage container 1. The pressure gauge 4 is used to monitor the pressure inside the gas storage container 1 in real time, providing accurate pressure data for operators and also providing pressure feedback signals for the automated control of the system.

[0049] In summary, the timed automatic drainage device proposed in this utility model can automatically open the drainage valve at preset time intervals through the timed electromagnetic drainage component installed at the bottom, ensuring timely discharge of condensate, effectively preventing internal corrosion of the gas storage container and damage to pneumatic equipment, and extending the service life of the equipment. At the same time, it requires no manual intervention, greatly improving drainage efficiency and reliability. Furthermore, the device has a simple structure, is easy to install, and is suitable for various industrial environments.

[0050] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
