Description

Technical Field

[0001] This application relates to the field of drainage device manufacturing, and more specifically, to a maintenance-free, zero-gas-consumption drainage device. Background Technology

[0002] In the prior art, automatic drainage devices used in air compressors, compressed air freeze dryers, or steam condensation systems are generally external drain valves connected to the container drain outlet, requiring periodic drainage. Since the drain valves are prone to damage and blockage, maintenance is frequent, resulting in gas loss. Therefore, those skilled in the art need to improve the existing drainage devices to overcome the above-mentioned defects. Utility Model Content

[0003] The main purpose of this application is to provide a maintenance-free, zero-gas-consumption drainage device. By reducing the size of the drainage pipe, a certain amount of liquid is formed at the bottom of the container, creating a water seal structure. This prevents gas loss when the drainage valve needs maintenance.

[0004] To achieve the above objectives, in a first aspect, this application provides a maintenance-free, zero-air-consumption drainage device, comprising a container body, packing material fixedly disposed within the container body, an air inlet and an air outlet opened on the container body, the air outlet and the air inlet being located on opposite sides of the packing material, and a filter drainage structure further disposed at the bottom of the container, the filter drainage structure comprising a drain outlet opened at the bottom of the container, a filter screen fixedly covered above the drain outlet, a sealing flange fixedly disposed at the drain outlet, a drain hole opened on the sealing flange, one end of a drain pipe being sealed and fixedly connected to the drain hole, a drain valve being disposed on the drain pipe, and the diameter of the drain pipe being less than one-fifth of the diameter of the drain outlet.

[0005] Optionally, the container may also include a liquid level detection element for detecting the liquid level inside the container, the liquid level detection element being electrically connected to the controller of the drain valve.

[0006] Optionally, it also includes an alarm device, wherein the liquid level detection element is electrically connected to the controller of the alarm device.

[0007] Optionally, the liquid level detection element is a liquid level gauge.

[0008] Optionally, the outer side of the sealing flange is provided with a wiring cavity for the liquid level detection element.

[0009] Optionally, it also includes an automatic cleaning device for automatically cleaning the filter screen.

[0010] Optionally, the automatic cleaning device includes at least one cleaning pipe fixedly installed at the bottom of the container, the cleaning pipe facing the filter screen, the cleaning pipe being connected to a cleaning water source via a control valve, and the controller of the control valve being electrically connected to the liquid level detection element.

[0011] The present invention provides a maintenance-free, zero-gas-consumption drainage device. Compared with the prior art, its advantages are as follows: First, the filter screen is set inside the container, which increases the area of ​​the filter screen and reduces the maintenance frequency of the filter screen. Second, the diameter of the drainage pipe is set to be less than one-fifth of the size of the drain outlet, thereby reducing the drainage efficiency. This allows a certain amount of liquid to accumulate at the bottom of the container, forming a water seal, thus avoiding gas loss when the drain valve needs maintenance. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a maintenance-free, zero-air-consumption drainage device includes a container body 1, a packing material 2 fixedly disposed within the container body 1, an air inlet 3 and an air outlet 4 opened on the container body 1, the air outlet 4 and the air inlet 3 being located on opposite sides of the packing material 2, and a filter drainage structure provided at the bottom of the container. The filter drainage structure includes a drain outlet opened at the bottom of the container and a filter screen 10 fixedly covered above the drain outlet. A sealing flange 7 is fixedly disposed at the drain outlet, and a drain hole is opened on the sealing flange 7. One end of a drain pipe 6 is sealed and fixedly connected to the drain hole. A drain valve 8 is provided on the drain pipe 6, and the diameter of the drain pipe 6 is less than one-fifth of the diameter of the drain outlet.

[0022] Principle: Since the conventional drain pipe 6 has the same dimensions as the drain outlet, meaning it's relatively large and has a high drainage flow rate, water can usually drain quickly from the bottom of the container after the drain valve 8 is opened. Therefore, when the drain valve 8 needs maintenance, especially during removal or replacement, gas loss from the container is likely. Furthermore, existing filter structures are usually located outside the container, and the filter area is typically matched to the diameter of the drain pipe 6, resulting in a relatively small filter surface. This easily leads to blockages, requiring frequent cleaning and further exacerbating gas loss. In this application's technical solution, the filter screen 10 is placed inside the container, and its area is not limited by the drain outlet, allowing it to be much larger than the outlet size. This effectively increases the filter area, reducing the maintenance frequency of the filter screen 10. Most importantly, the drain pipe 6's diameter is designed to be much smaller than the drain outlet size, thus reducing the drainage flow rate. After the drain valve 8 is opened, the liquid squeezed at the bottom of the container does not drain quickly but forms a liquid layer, creating a water seal structure. This prevents gas loss during drain valve 8 maintenance.

[0023] In order to enable automatic drainage, a liquid level detection element is also included for detecting the liquid level in the container. The liquid level detection element is electrically connected to the controller of the drain valve 8. Preferably, the liquid level detection element is a liquid level gauge 5.

[0024] In order to enable automatic alarm when the filter screen 10 is clogged, an alarm device is also included, and the liquid level detection element is electrically connected to the controller of the alarm device.

[0025] To improve the sealing effect, the outer side of the sealing flange 7 is provided with the wiring cavity 9 of the liquid level detection element.

[0026] In order to enable automatic cleaning of the filter screen 10 inside the container, an automatic cleaning device is also included for automatic cleaning of the filter screen 10. The automatic cleaning device includes at least one cleaning pipe 11 fixedly installed at the bottom of the container. The cleaning pipe 11 is directly facing the filter screen 10. The cleaning pipe 11 is connected to the cleaning water source through a control valve 12. The controller of the control valve 12 is electrically connected to the liquid level detection element.

[0027] The automatic drainage principle is as follows: The automatic drainage device is installed at the bottom of the container. The level gauge 5 detects the liquid level and controls the opening and closing of the drain valve 8 (solenoid valve). When the liquid level reaches the high point, automatic drainage begins; when the liquid level drops to the low point, drainage stops; when the liquid level rises to the alarm level, the drain valve 8 opens, forcibly draining the liquid and simultaneously triggering a fault alarm to remind the user to clean the filter screen 10. The filter screen 10 is cleaned by connecting high-pressure gas or water to the flushing port valve and flushing through the built-in flushing pipe in the container, allowing for cleaning without disassembly. An automatic valve can also be installed to automatically activate the cleaning mode after a liquid level alarm.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
