Drainage mechanism for air compressor tank

Abstract

This invention discloses a drainage mechanism for an air compressor's air tank, comprising two supports. The tops of the two supports are fixedly connected to the air tank body. A drain pipe is fixedly connected to the bottom of the outer wall of the air tank body. One end of the drain pipe is fixedly connected to a valve seat. A rotating shaft is rotatably connected to one side of the inner wall of the valve seat. A spherical baffle is fixedly connected to one end of the rotating shaft. This invention utilizes the coordinated use of a liquid level sensor, valve seat, rotating shaft, and drive assembly to avoid drainage anomalies caused by interference or false triggering of a single sensor through the coordinated judgment of two liquid level sensors. This ensures that the drainage action only starts when the accumulated water reaches a set threshold, preventing frequent start-stop cycles. Furthermore, it employs an electric telescopic rod driven by a gear-rack transmission instead of a traditional solenoid valve, resulting in high transmission accuracy, strong impact resistance, reduced risk of valve jamming or sealing failure, fast response speed, and lower maintenance costs compared to solenoid valves.

Description

Technical Field

[0001] This utility model relates to the field of air tank drainage technology, and in particular to a drainage mechanism for an air compressor air tank. Background Technology

[0002] In industrial production, air compressors are commonly used equipment, generating power by compressing air. The air compressor's receiver tank stores compressed air and often accumulates moisture. This moisture is formed by the condensation of water vapor in the air during compression. Excessive water accumulation inside the receiver tank not only affects the equipment's performance but can also lead to corrosion and reduce the air compressor's lifespan. Therefore, effectively removing water from the air receiver tank is a crucial task in the operation of air compressors.

[0003] A search revealed application number 202222535209.0, which discloses a drainage mechanism for an air compressor's storage tank. The mechanism includes an air tank body with a drainage device at its bottom. The drainage device comprises a drainage assembly and a filter assembly mounted on the drainage assembly. A drain pipe is mounted on the filter assembly. The drainage assembly includes a water inlet tank and a moving assembly. A groove is formed on the inner wall of the water inlet tank, and the bottom of the water inlet tank is connected to the inner wall of the air tank body. Multiple water inlets are formed on the inner wall of the groove, and the moving assembly is located within the groove. This device can automatically drain water from the air storage tank without manual intervention.

[0004] Traditional drainage systems are mostly manual or simple automatic systems, which have certain limitations. Manual drainage requires human intervention, which is cumbersome and unsuitable for environments where no one is on duty for a long time. While some automatic drainage systems can drain water automatically, they lack intelligent control and cannot achieve more precise water level detection and drainage operations, resulting in untimely drainage or inability to cope with complex water accumulation situations. At the same time, existing filtration devices mostly use fixed filter screens or Y-type filters, which require complete disassembly and cleaning when the filter element is clogged. This is cumbersome and results in long downtime. Although some designs use detachable filter cartridges, it is difficult to completely remove the sediment at the bottom, which can easily cause secondary pollution. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a drainage mechanism for an air compressor storage tank.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a drainage mechanism for an air compressor storage tank, comprising two supports, the top of the two supports being fixedly connected to the storage tank body, a drain pipe being fixedly connected to the bottom of the outer wall of the storage tank body, a valve seat being fixedly connected to one end of the drain pipe, a rotating shaft being rotatably connected to one side of the inner wall of the valve seat, a spherical baffle being fixedly connected to one end of the rotating shaft, a drive assembly capable of automatically controlling the rotation of the spherical baffle being provided on the outer wall of the valve seat, a cross tube being fixedly connected to one end of the valve seat, two limiting frames being fixedly connected to the inner wall of the cross tube, an installation assembly being provided on the outer wall of the cross tube, and a cleaning assembly being provided on the outer wall of the cross tube and below the installation assembly.

[0007] The support bracket supports the air tank body to ensure equipment stability and reduce the impact of vibration on the drainage mechanism. The air tank body stores compressed air and condensate, and has two built-in liquid level sensors arranged vertically to monitor the water level and trigger a drainage signal. The drain pipe connects the air tank body to the valve seat to guide the water out. The valve seat, as the housing of the drainage channel, has a built-in spherical baffle and sealing ring. The opening and closing of the drainage is controlled by a rotating shaft. The cross tube connects the valve seat to the discharge pipe and has a filter cartridge installed inside to filter the drainage. The limit frame is embedded in the inner wall of the cross tube and slides with the positioning plate of the filter cartridge to ensure that the filter cartridge is installed vertically and prevents sealing failure caused by tilting.

[0008] As a further description of the above technical solution:

[0009] The drive assembly is fixedly mounted on the electric telescopic rod on the outer wall of the valve seat via a support plate. The telescopic end of the electric telescopic rod is fixedly connected to a rack, and the bottom of the rack is meshed with a gear.

[0010] The central hole of the gear is fixedly connected to one end of the rotating shaft extending to the outside of the valve seat via a keyway. The electric telescopic rod receives the controller signal, and the telescopic end pushes the rack to move linearly. The rack and gear can convert the linear motion of the telescopic rod into the rotational power of the gear, driving the rotating shaft and the spherical baffle to rotate, accurately controlling the opening and closing of the drainage channel. The gear and rack transmission has high precision, is resistant to high pressure impact, and has a fast response speed, which is superior to traditional solenoid valves.

[0011] As a further description of the above technical solution:

[0012] The installation assembly includes an externally threaded sleeve threaded to the outer wall of the cross tube, a connecting rod rotatably connected to the inner top surface of the externally threaded sleeve, a crossbar fixedly connected to the bottom end of the connecting rod, and filter cartridges fixedly connected to both ends of the crossbar.

[0013] The external threaded sleeve is connected to the cross tube by threads. When rotated, it can drive the filter cartridge to rise and fall, realizing quick disassembly and assembly. The filter cartridge filters impurities in the drainage and adopts a replaceable design to adapt to different filtration precision requirements.

[0014] As a further description of the above technical solution:

[0015] A sealing ring is fixedly connected to the top of the filter cartridge, and two positioning plates are fixedly connected to the outer wall of the filter cartridge.

[0016] The outer wall of the positioning plate is slidably connected to the inside of the limiting frame, and the sealing ring is located at the top of the filter cylinder, pressing the inner wall of the cross tube to prevent unfiltered water from leaking.

[0017] As a further description of the above technical solution:

[0018] The cleaning assembly includes a threaded fixing cylinder that is threaded to the outer wall of the cross tube and located below the mounting assembly. A turntable is fixedly connected to the bottom of the threaded fixing cylinder, and a pad is fixedly connected to the inner bottom surface of the threaded fixing cylinder.

[0019] The threaded retaining cylinder is removed by rotating the turntable, the bottom channel of the cross tube is opened, the deposited impurities are cleaned, and the bottom of the cross tube is sealed with a gasket to prevent water leakage during drainage and to buffer the impact of impurities.

[0020] As a further description of the above technical solution:

[0021] One end of the cross tube is fixedly connected to a discharge pipe.

[0022] The outlet of the filtered water from the drain pipe is connected to the external drainage system.

[0023] As a further description of the above technical solution:

[0024] The outer wall of the spherical baffle has two sealing rings in sliding contact.

[0025] The sealing ring is fixedly connected to the inner wall of the valve seat. The sealing ring is fixed to the inner wall of the valve seat and slides in contact with the spherical baffle to ensure the sealing performance when the ball valve is closed.

[0026] As a further description of the above technical solution:

[0027] The gas storage tank body has an inlet pipe and an outlet pipe fixedly connected to both ends, and a safety valve is fixedly connected to the outer wall of the outlet pipe. Two liquid level sensors are fixedly installed on the inner wall of the gas storage tank body.

[0028] 1. Compared with the prior art, the beneficial effects of this utility model include: by using the combination of liquid level sensor, valve seat, rotating shaft and drive assembly, the drainage abnormality caused by impurity interference or false triggering of a single sensor can be avoided through the coordinated judgment of the upper and lower liquid level sensors. This ensures that the drainage action is only started when the water accumulation reaches the set threshold, preventing frequent start and stop. Furthermore, the electric telescopic rod is used to drive the gear-rack transmission instead of the traditional solenoid valve, which has high transmission accuracy, strong impact resistance, reduces the risk of valve jamming or sealing failure, and has a fast response speed and lower maintenance cost than solenoid valves.

[0029] 2. Compared with the prior art, the beneficial effects of this utility model include: through the combined use of structures such as the cross tube, the limiting frame, the installation component and the cleaning component, the filter cartridge is connected to the cross tube through the top external threaded sleeve. The filter cartridge can be vertically extracted by simply rotating the sleeve, avoiding the cumbersome operation of disassembling the pipe horizontally in traditional Y-type filters, shortening the cleaning time. In addition, a threaded fixing cylinder is set separately at the bottom of the cross tube, and the deposited impurities can be opened by rotating the turntable without disassembling the entire filter device, reducing downtime.

[0038] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0039] According to one embodiment of the present invention, in conjunction with Figure 1-6A drainage mechanism for an air compressor's air tank is shown. It includes two supports 1, with the top of the two supports 1 fixedly connected to an air tank body 2. A drain pipe 3 is fixedly connected to the bottom of the outer wall of the air tank body 2. One end of the drain pipe 3 is fixedly connected to a valve seat 4. A rotating shaft 5 is rotatably connected to one side of the inner wall of the valve seat 4. A spherical baffle 6 is fixedly connected to one end of the rotating shaft 5. A drive assembly capable of automatically controlling the rotation of the spherical baffle 6 is provided on the outer wall of the valve seat 4. A cross tube 7 is fixedly connected to one end of the valve seat 4. Two limit frames 8 are fixedly connected to the inner wall of the cross tube 7. An installation assembly is provided on the outer wall of the cross tube 7, and a cleaning assembly is provided on the outer wall of the cross tube 7 below the installation assembly. The supports 1 support the air tank body 2 to ensure equipment stability and reduce the impact of vibration on the drainage mechanism. The air tank body 2 stores compressed air and condensate, and has two vertically arranged liquid level sensors 26 built-in to monitor the accumulated water level and trigger a drainage signal. The drain pipe 3 connects the air tank body 2 and the valve seat 4. The valve seat 4 serves as the housing for the drainage channel, housing a spherical baffle 6 and a sealing ring 22. The opening and closing of the drainage is controlled by a rotating shaft 5. A cross tube 7 connects the valve seat 4 to the discharge pipe 21, and a filter cartridge 15 is installed inside to filter the drainage. A limiting frame 8 is embedded in the inner wall of the cross tube 7 and slides in cooperation with the positioning plate 17 of the filter cartridge 15, ensuring the filter cartridge 15 is installed vertically and preventing sealing failure due to tilting. Through the coordinated use of the liquid level sensor 26, valve seat 4, rotating shaft 5, and drive assembly, the coordinated judgment of the two liquid level sensors 26 avoids drainage abnormalities caused by interference or false triggering of a single sensor. This ensures that the drainage action only starts when the accumulated water reaches a set threshold, preventing frequent start-stop cycles. Furthermore, an electric telescopic rod 9 drives a gear 11-rack 10 transmission instead of a traditional solenoid valve, resulting in high transmission accuracy, strong impact resistance, reduced risk of valve jamming or sealing failure, fast response speed, and lower maintenance costs compared to solenoid valves.

[0040] The drive assembly is fixedly mounted on the outer wall of the valve seat 4 by a support plate. The telescopic end of the electric telescopic rod 9 is fixedly connected to a rack 10, and the bottom of the rack 10 is meshed with a gear 11. The center hole of the gear 11 is fixedly connected to one end of the rotating shaft 5 extending to the outside of the valve seat 4 through a keyway. The electric telescopic rod 9 receives a signal from the controller, and the telescopic end pushes the rack 10 to perform linear motion. The rack 10 and the gear 11 can convert the linear motion of the telescopic rod into the rotational power of the gear 11, which drives the rotating shaft 5 and the spherical baffle 6 to rotate, accurately controlling the opening and closing of the drainage channel. The gear 11 and rack 10 have high transmission accuracy, are resistant to high pressure impact, and have a fast response speed, which is superior to traditional solenoid valves.

[0041] The mounting assembly includes an externally threaded sleeve 12 threaded to the outer wall of the cross tube 7. A connecting rod 13 is rotatably connected to the inner top surface of the externally threaded sleeve 12. A crossbar 14 is fixedly connected to the bottom end of the connecting rod 13. Filter cartridges 15 are fixedly connected to both ends of the crossbar 14. The externally threaded sleeve 12 is connected to the cross tube 7 by threads. Rotation can drive the filter cartridge 15 to rise and fall, enabling quick assembly and disassembly. The filter cartridge 15 filters impurities in the drainage and adopts a replaceable design to adapt to different filtration precision requirements. A sealing ring 16 is fixedly connected to the top of the filter cartridge 15. Two positioning plates 17 are fixedly connected to the outer wall of the filter cartridge 15. The outer wall of the positioning plate 17 is slidably connected to the inside of the limiting frame 8. The sealing ring 16 is located at the top of the filter cartridge 15, pressing against the inner wall of the cross tube 7 to prevent unfiltered water from leaking.

[0042] The cleaning assembly includes a threaded retaining cylinder 18 that is threaded to the outer wall of the cross tube 7 and located below the mounting assembly. A turntable 19 is fixedly connected to the bottom of the threaded retaining cylinder 18, and a gasket 20 is fixedly connected to the inner bottom surface of the threaded retaining cylinder 18. The threaded retaining cylinder 18 is disassembled by rotating the turntable 19 to open the bottom channel of the cross tube 7 and clean the deposited impurities. The gasket 20 seals the bottom of the cross tube 7 to prevent water leakage during drainage and to buffer the impact of impurities.

[0043] One end of the cross tube 7 is fixedly connected to the discharge pipe 21. The outlet of the filtered clean water in the discharge pipe 21 is connected to the external drainage system. The outer wall of the ball baffle 6 has two sealing rings 22 in sliding contact. The sealing rings 22 are fixedly connected to the inner wall of the valve seat 4. The sealing rings 22 are fixed to the inner wall of the valve seat 4 and in sliding contact with the ball baffle 6 to ensure the sealing performance when the ball valve is closed.

[0044] The two ends of the gas storage tank body 2 are respectively fixedly connected to an inlet pipe 23 and an outlet pipe 24. A safety valve 25 is fixedly connected to the outer wall of the outlet pipe 24. Two liquid level sensors 26 are fixedly installed on the inner wall of the gas storage tank body 2.

[0045] The working principle of this embodiment is as follows: First, during use, when the water accumulated inside the gas storage tank 2 exceeds the two liquid level sensors 26 arranged vertically, an electrical signal is transmitted to the controller (not shown). Then, the controller controls the electric telescopic rod 9 to start, causing its telescopic end to extend and retract, driving the rack 10 to move. The rack 10 then moves along the inside of the frame and meshes with the gear 11, causing the gear 11 to rotate. This, in turn, drives the rotating shaft 5 to rotate, causing the spherical baffle 6 located inside the valve seat 4 to rotate. This changes the angle of the spherical baffle 6, no longer obstructing the closure of the pipeline, allowing the water accumulated in the gas storage tank 2 to drain out. Then, when the water in the gas storage tank 2 drops to the liquid level sensor 26 located below, a signal is transmitted to the controller, causing the controller to control the electric telescopic rod 9 to retract, closing the pipeline and stopping drainage. Compared to traditional solenoid valves, this mechanical structure is more resistant to high-pressure impacts, and the gear 11 has high transmission precision, enabling rapid response.

[0046] When the water is discharged from one end of the valve seat 4, it enters the cross tube 7. Then, the water flows through the filter cartridge 15 and is discharged from the outlet pipe 21. When the filter cartridge 15 has accumulated a lot of impurities and needs to be cleaned, the external threaded sleeve 12 can be rotated to disconnect it from the threaded connection with the cross tube 7. Then, the external threaded sleeve 12 can be lifted, which will move the connecting rod 13 and the cross rod 14 to lift the filter cartridge 15. After cleaning the debris from the filter cartridge 15, the filter cartridge 15 is placed vertically with its inlet aligned with the connection end between the valve seat 4 and the cross tube 7, allowing impurities to enter the filter cartridge 15. Finally, the positioning plate 17 on the filter cartridge 15 is aligned. The limiting frame 8 inside the cross tube 7 allows the positioning plate 17 to slide along the inner wall of the limiting frame 8. Then, the external threaded sleeve 12 is rotated. At this time, the external threaded sleeve 12 rotates and presses down, while the filter cartridge 15 will move vertically downward due to the rotation of the connecting rod 13 and the limiting of the positioning plate 17, thereby completing the disassembly and installation of the filter cartridge 15. After long-term use, impurities will accumulate at the bottom of the cross tube 7. When cleaning is required, simply rotate the turntable 19 to rotate the threaded fixing sleeve 18 to release the threaded fixing with the cross tube 7, thereby cleaning the impurities at the bottom of the cross tube 7. During installation, simply align and then rotate in the opposite direction to easily complete the installation and facilitate the cleaning of deposited impurities.

[0047] 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.
