Automatic blowdown structure of gas system

Abstract

This invention proposes an automatic sewage discharge structure for a gas system, including a separation cylinder with a sealing cap at one end and a collector at the bottom. A support rod is fixedly connected to one side of the sealing cap, and a spiral guide plate is fixedly connected to the outer surface of the support rod. This invention relates to the field of gas systems. By using the spiral guide plate inside the separation cylinder, the gas forms a rotating airflow, utilizing centrifugal force to efficiently throw liquid and solid particles towards the inner wall of the separation cylinder. Furthermore, with the directional guidance of the guide hood, impurities flow into the collector via the upper and lower connecting plates, improving the gas-liquid and gas-solid separation effect and effectively preventing impurities from entering subsequent systems with the gas, causing blockages or equipment damage. A capacitive liquid level sensor monitors the liquid level in the collector in real time. When a set threshold is reached, the PLC controller automatically triggers the solenoid valve to open and discharge sewage, eliminating the need for manual intervention and reducing labor costs.

Description

Technical Field

[0001] This utility model relates to the field of gas systems, specifically an automatic sewage discharge structure for gas systems. Background Technology

[0002] A gas system is a system composed of gas source equipment, pipelines, control components, actuators, etc., used for transporting, processing and utilizing gases. It is widely used in industrial production, energy supply, machinery manufacturing and other fields. During the gas transport process, the gas often contains liquid or solid impurities such as moisture, oil, and dust. If these impurities are not removed in time, they will flow with the gas in the system, which may lead to problems such as pipeline blockage, valve jamming, and equipment wear, affecting the stable operation and service life of the gas system.

[0003] However, existing gas system drainage structures mostly rely on manual periodic drainage, which consumes labor costs. Moreover, the drainage time depends entirely on experience, which can easily lead to untimely drainage causing the accumulation of impurities or frequent drainage causing gas waste, thus reducing the drainage effect. To address these issues, we propose an automatic gas system drainage structure. Utility Model Content

[0017] According to one embodiment of the present invention, in conjunction with the appended drawings Figure 1-4 As shown.

[0018] An automatic sewage discharge structure for a gas system includes a separation cylinder 1, a sealing cap 2 at one end of the separation cylinder 1, a collector 3 below the separation cylinder 1, a support rod 4 fixedly connected to one side of the sealing cap 2, a spiral guide plate 5 fixedly connected to the outer surface of the support rod 4, a guide shroud 7 fixedly connected to the bottom surface of the separation cylinder 1, an upper connecting plate 8 fixedly connected to the bottom surface of the guide shroud 7, a lower connecting plate 9 fixedly connected to the bottom surface of the upper connecting plate 8, and a capacitive liquid level sensor 10 fixedly installed on the inner bottom wall of the collector 3. The capacitive liquid level sensor 10 is a variable dielectric capacitor that utilizes the change in capacitance caused by the change in the surface of the measured medium. It consists of two coaxial cylindrical inner electrodes and an outer electrode, with a metal rod serving as one of the capacitors. The container wall acts as another stage of the capacitor. The medium between the two electrodes is liquid and air. The dielectric constants of liquid and air are different. When liquid enters the container, it causes a change in the capacitance between the sensor housing and the sensing electrode, outputting standard current, voltage, or digital signals. The bottom surface of collector 3 is fixedly connected to drain pipe 11, and the outer surface of drain pipe 11 is fixedly connected to solenoid valve 12. Collector 3 is used to collect the separated impurities and realize gas-sludge separation. Spiral guide plate 5 can guide the gas in the separation cylinder 1 to form a rotating airflow, and separate impurities by means of centrifugal force. Capacitive liquid level sensor 10 monitors the impurity liquid level in collector 3 and can provide a signal for sewage discharge. Drain pipe 11 is the channel for impurity discharge, and solenoid valve 12 controls its opening and closing to realize automatic sewage discharge.

[0019] In this embodiment, one end of the separator cylinder 1 is fixedly connected to an air inlet pipe 16, and one end of the air inlet pipe 16 is fixedly connected to an air inlet flange 17. A threaded connecting ring 18 is fixedly connected to the outer surface of the separator cylinder 1. The inner ring of the sealing cover 2 is threadedly connected to the outer surface of the threaded connecting ring 18. A limiting ring 19 is fixedly connected to the inner ring of the separator cylinder 1. An annular sealing gasket 20 is provided on one side of the limiting ring 19. One side of the annular sealing gasket 20 is in close contact with one side of the sealing cover 2. The air inlet pipe 16 provides a channel for the gas containing impurities to enter the separator cylinder 1. The air inlet flange 17 facilitates the connection of the air inlet pipe 16 to external equipment. The threaded connecting ring 18 enables the sealing cover 2 and the separator cylinder 1 to be connected by threads, which is convenient for loading and unloading. The limiting ring 19 limits the annular sealing gasket 20. The annular sealing gasket 20 enhances the sealing performance between the sealing cover 2 and the separator cylinder 1, preventing gas leakage.

[0020] In this embodiment, a support plate 13 is fixedly connected to one side of the flow guide shroud 7, and a PLC controller 14 is fixedly installed on one side of the support plate 13. An exhaust pipe 15 is provided above the separation cylinder 1, and the bottom end of the exhaust pipe 15 penetrates through the separation cylinder 1 and extends into the interior of the separation cylinder 1. A rotating protrusion 21 is provided on one side of the sealing cover 2. A ring-shaped support seat 22 is fixedly connected to the bottom surface of the collector 3. A collection hole 6 is opened on the upper surface of the separation cylinder 1. The collection hole 6 is located below the upper connecting plate 8. The support plate 13 can provide installation support for the PLC controller 14. The PLC controller 14 receives the signal from the capacitive liquid level sensor 10 and controls the solenoid valve 12. It is the control core for automatic sewage discharge. The exhaust pipe 15 is used to discharge the purified gas. The rotating protrusion 21 facilitates the rotation of the sealing cover 2 and is easy to operate. The support seat 22 provides stable support for the collector 3. The collection hole 6 ensures that impurities in the separation cylinder 1 can smoothly enter the upper connecting plate 8, ensuring the smooth flow channel.

[0021] Working principle: First, the gas containing impurities enters the separator 1 through the inlet pipe 16. The spiral guide plate 5 enables the gas to form a rotating airflow in the separator 1. Under the action of centrifugal force, the liquid and solid particles in the gas are thrown towards the inner wall of the separator 1 and slide down the wall to the guide shroud 7. Then, the liquid and impurities enter the upper connecting plate 8 and flow into the collector 3 through the lower connecting plate 9. Then, the capacitive liquid level sensor 10 in the collector 3 monitors the impurity liquid level in real time. When the liquid level reaches the set threshold, the capacitive liquid level sensor 10 transmits the signal to the PLC controller 14. The PLC controller 14 triggers the solenoid valve 12 on the drain pipe 11 to open. The impurities and liquid in the collector 3 are automatically discharged through the drain pipe 11. After the discharge is completed, the PLC controller 14 controls the solenoid valve 12 to close, waiting for the next discharge.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
