Description

Technical Field

[0001] This utility model relates to the discharge of condensate from compressed air, and more particularly to a device for discharging condensate from compressed air. Background Technology

[0002] Compressed air is the second largest energy source after electricity and a versatile process gas source, used in industries and sectors such as petroleum, chemical, metallurgy, power, machinery, light industry, textiles, automobile manufacturing, electronics, food, pharmaceuticals, biochemistry, defense, and scientific research. However, compressed air contains a significant amount of impurities, primarily: solid particles—in a typical large city environment, there are approximately 140 million particles per cubic meter of air, about 80% of which are smaller than 2μm, which air compressor intake filters cannot eliminate. Furthermore, the air compressor system continuously generates wear debris, rust, and oil carbon deposits, which accelerate the wear of air-using equipment and lead to seal failure; moisture—the relative humidity in the atmosphere is generally above 65%, and after compression and condensation, it becomes saturated air, carrying a large amount of liquid water droplets. These are the root cause of corrosion in equipment, pipes, and valves, and in winter, they can freeze and block small orifices in pneumatic systems. It is worth noting that even when the air is completely separated and saturated, condensation will still occur as the temperature decreases. For every 10°C decrease, the saturated water content will drop by about 50%, meaning that half of the water vapor will be converted into liquid water droplets.

[0003] Compressed air is a primary source of safe power in the shipbuilding and repair industry. Due to the physical properties of compressed air, a certain amount of condensate exists in compressed air pipelines. This condensate is highly corrosive, and excessive moisture in storage tanks and pipelines can seriously affect operational production. In order to solve the problem of moisture content in compressed air supply systems, a condensate drainage device for compressed air is proposed. Utility Model Content

The low water level sensor switch is located at the top of the drain pipe, and the high water level sensor switch is located at the bottom of the inlet pipe.

[0007] Furthermore, a plurality of water level sensors are provided, and the plurality of water level sensors are evenly distributed between the bottom of the high water level sensor switch and the top of the low water level sensor switch.

[0008] Furthermore, the electronic control device is fixedly installed on the side wall of the enclosure;

[0011] Furthermore, the buffer valve, the drain solenoid valve, the temperature control heating tube, the low water level sensor switch, the high water level sensor switch, and the water level sensor are all connected to the electronic control device via wires;

[0012] Furthermore, the dirt isolation mechanism includes a partition and a drain pipe. The partition is fixedly installed on the inner wall of the box. The gap between the bottom of the partition and the inside of the box forms a dirt storage area. The drain pipe is fixedly installed inside the box. One end of the drain pipe is connected to the dirt storage area, and the other end of the drain pipe is equipped with a top cover. A second discharge hole is opened inside the partition.

[0013] Furthermore, the drain pipe is located at the top of the partition;

[0014] Furthermore, the partition is a V-shaped plate;

[0015] Furthermore, an installation component is fixedly installed inside the partition plate. The installation component is a hollow arched cylinder, and a first discharge hole is opened at one end of the installation component.

[0016] Beneficial effects:

[0017] This utility model discloses a condensate drainage device for compressed air. The device is installed at the lower end of an air tank or pipeline. Wastewater from the compressed air pipeline flows into the device through an inlet pipe. A water level sensor detects the water level inside the device. When the wastewater reaches a set height, a drain solenoid valve opens, allowing the wastewater to drain through the drain pipe. Simultaneously, a buffer valve inside the inlet pipe closes rapidly to stop water intake. When the wastewater reaches the low water level sensor switch, the drain solenoid valve closes, thus achieving the goal of draining water without venting it. This effectively reduces energy consumption and solves the problem of condensate drainage in compressed air supply systems. Attached Figure Description

[0030] Reference Figure 1-5 An embodiment of the present invention provides a condensate discharge device for compressed air, comprising a housing 1 and an electrical control device 2. The housing 1 is equipped with a dirt isolation mechanism and a discharge mechanism.

[0031] The discharge mechanism includes an inlet pipe 3, a drain pipe 5, a low water level sensor 8, a high water level sensor 9, and a water level sensor 10. The inlet pipe 3 is fixedly installed on the side wall of the tank 1 near the top, and one end of the inlet pipe 3 is connected to the inside of the tank 1. A buffer valve 4 is fixedly installed inside the inlet pipe 3. The drain pipe 5 is fixedly installed on the side wall of the tank 1 near the bottom, and one end of the drain pipe 5 is connected to the inside of the tank 1. A drain solenoid valve 6 is fixedly installed inside the drain pipe 5. The low water level sensor 8, the high water level sensor 9, and the water level sensor 10 are all fixedly installed inside the tank 1. The low water level sensor 8 is located at the top of the drain pipe 5, and the high water level sensor 9 is located at the bottom of the inlet pipe 3. Several water level sensors 10 are provided, and the several water level sensors 10 are evenly distributed between the bottom of the high water level sensor 9 and the top of the low water level sensor 8.

[0032] The system includes an inlet pipe 3 to allow external sewage to flow into the tank 1, a buffer valve 4 to control the opening and closing of the inlet pipe 3, a drain pipe 5 to allow sewage inside the tank 1 to be discharged, a drain solenoid valve 6 to control the opening and closing of the second drain pipe 5, and a low water level sensor 8, a high water level sensor 9, and a water level sensor 10 to detect the water level inside the tank 1.

[0033] In this embodiment, the housing 1 is installed at the lower end of the air tank or pipeline. Wastewater from the compressed air pipeline flows into the housing 1 through the water inlet pipe 3. The water level sensor 10 detects the water level inside the housing 1. When the wastewater reaches a set height, the drain solenoid valve 6 opens, allowing the wastewater inside the housing 1 to be discharged through the drain pipe 5. At the instant the drain solenoid valve 6 opens, the buffer valve 4 inside the water inlet pipe 3 quickly closes to stop the water inflow. Simultaneously, the core of the buffer valve 4 has a vent hole that replenishes a certain pressure inside the housing 1 to quickly drain the wastewater and also reduce the water level. Noise during drainage: When the sewage in tank 1 is discharged to the position of the low water level sensor switch 8, the drain solenoid valve 6 is closed, thus achieving the purpose of draining without venting. Draining without venting can effectively reduce energy consumption. When the drain solenoid valve 6 is closed, the pressure in tank 1 is balanced, and the buffer valve 4 in the inlet pipe 3 opens to re-introduce sewage into tank 1. When the normal discharge valve control system fails, the water level in the drainage tank will be too high and will trigger the high water level sensor switch 9. At this time, the drain solenoid valve 6 will open to empty all the sewage and gas in tank 1 to avoid equipment damage caused by water accumulation.

[0034] In one embodiment, the electronic control device 2 is fixedly installed on the side wall of the box 1. A temperature-controlled heating tube 11 is fixedly installed inside the box 1. The temperature-controlled heating tube 11 is spirally and evenly wound inside the box 1. The buffer valve 4, the drain solenoid valve 6, the temperature-controlled heating tube 11, the low water level sensor switch 8, the high water level sensor switch 9, and the water level sensor 10 are all connected to the electronic control device 2 through wires.

[0035] In this embodiment, an electronic control device 2 is provided to control the buffer valve 4, the drain solenoid valve 6, the temperature control heating tube 11, the low water level sensor switch 8, the high water level sensor switch 9, and the water level sensor 10. The temperature control heating tube 11 can be used to adjust the temperature of the sewage inside the tank 1. The electronic control device 2 uses components that are already in use in the prior art.

[0036] In one embodiment, the dirt isolation mechanism includes a partition 14 and a drain pipe 7. The partition 14 is fixedly installed on the inner wall of the housing 1. The gap between the bottom of the partition 14 and the inside of the housing 1 forms a dirt storage area 12. The drain pipe 7 is fixedly installed inside the housing 1. One end of the drain pipe 7 is connected to the dirt storage area 12, and the other end of the drain pipe 7 is equipped with a top cover. A second discharge hole 17 is opened inside the partition 14. A drain pipe 5 is located at the top of the partition 14. The partition 14 is a V-shaped plate. An installation component 15 is fixedly installed inside the partition 14. The installation component 15 is a hollow arched cylinder. A first discharge hole 16 is opened at one end of the installation component 15.

[0037] In this embodiment, a top cover is provided to block the sewage pipe 7. By setting a partition 14, the internal space of the tank 1 can be divided to form a dirt storage area 12. When sewage enters the tank 1, the dirt settles down and accumulates on the top of the partition 14 due to gravity. At this time, the dirt flows into the dirt storage area 12 through the first discharge hole 16 and the second discharge hole 17 inside the partition 14. By setting the second discharge hole 17 inside the mounting part 15, the backflow of dirt can be effectively prevented. During treatment, the dirt in the dirt storage area 12 can be discharged simply by opening the top cover.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
