Description

Technical Field

[0001] This utility model relates to the field of air tank technology, specifically an automatic drainage device for an air compressor air tank. Background Technology

[0002] An air compressor receiver tank, also known as a compressed air storage tank, is a pressure vessel specifically designed for storing compressed air. Its function is to buffer the air supply, prevent frequent loading and unloading of the air compressor, and remove most of the liquid water. It is mainly used in conjunction with air compressors, refrigerated dryers, filters, and other equipment to form a compressed air power station for industrial production.

[0003] If the air compressor's air tank is not drained in time, excessive water accumulation inside the tank will affect the quality of compressed air and may also cause corrosion of the tank. In severe cases, it may even lead to safety accidents, such as tank rupture. Therefore, a drainage device is needed to ensure safe and stable operation.

[0004] In the existing technology, the air compressor's air tank is manually drained periodically. However, manual draining may lead to excessive water accumulation due to untimely drainage, which can damage the equipment and even reduce its service life. Furthermore, in some low-temperature environments, the condensate in the air tank may freeze, preventing normal drainage and affecting the normal use of the air tank. Utility Model Content

[0005] This invention provides an automatic drainage device for an air compressor's air tank to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic drainage device for an air compressor storage tank, comprising an air storage tank body, a partition plate fixedly installed on the inner wall of the air storage tank body near the lower side, and drainage holes evenly distributed along the circumference of the partition plate; a cylinder fixedly installed at the middle of the lower side wall of the air storage tank body, the upper surface of the cylinder being an open structure; a sealing mechanism fixedly installed on the lower surface of the cylinder, the sealing mechanism being vertically and vertically corresponding to the drainage holes; a drain pipe fixedly installed on the right side of the cylinder, a drainage mechanism being provided on the right side of the drain pipe; a control mechanism fixedly installed on the front side of the air storage tank body near the lower side; and a heating mechanism installed on the lower side wall of the air storage tank body near the front and rear sides.

A mounting plate is fixedly installed on the upper surface of the support rod. A rubber plug is provided on the upper surface of the mounting plate at a position corresponding to the leakage hole.

[0008] Furthermore, a through hole is provided on the lower side wall of the corresponding cylinder of the electric telescopic rod, and the diameter of the mounting plate is half of the inner diameter of the main body of the gas storage tank.

[0009] Furthermore, the drainage mechanism includes a solenoid valve, a Y-type filter, and a water outlet pipe, which are fixedly installed on the right side of the drainage pipe from left to right.

[0010] Furthermore, the control mechanism includes a controller, a first liquid level sensor, and a second liquid level sensor. The controller is installed on the front side of the gas storage tank body.

[0013] Compared with the prior art, this utility model provides an automatic drainage device for air compressor storage tanks, which has the following beneficial effects:

[0014] 1. This automatic drainage device for the air compressor's air tank monitors the liquid level inside the tank via a control mechanism. When drainage is required, the sealing mechanism blocks the leak hole, and the water is then discharged through the drainage mechanism. This adds an automatic drainage function to the air tank, making installation and operation simple and convenient. It greatly reduces the tediousness of manual drainage, ensures the long-term stable and reliable operation of the air tank, and the automatic drainage water will not affect the use of the air tank, thus improving the stability of the overall air system.

[0015] 2. The automatic drainage device for the air compressor's air tank increases the heating function of the main body of the air tank by setting a heating mechanism, which prevents the condensate in the main body of the air tank from freezing and ensures smooth drainage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses an automatic drainage device for an air compressor storage tank, including an air storage tank body 1. A partition 2 is fixedly installed on the inner wall of the air storage tank body 1 near the lower side. Drainage holes 3 are evenly opened along the circumference of the partition 2. A cylinder 4 is fixedly installed in the middle of the lower side wall of the air storage tank body 1, and the upper surface of the cylinder 4 is an open structure. A sealing mechanism 5 is fixedly installed on the lower surface of the cylinder 4, and the sealing mechanism 5 is arranged vertically and vertically corresponding to the drainage holes 3. A drain pipe 6 is fixedly installed on the right side of the cylinder 4, and a drainage mechanism 7 is provided on the right side of the drain pipe 6. A control mechanism 8 is fixedly installed on the front side of the air storage tank body 1 near the lower side. A heating mechanism 9 is installed on the lower side wall of the air storage tank body 1 near the front and rear. The figure shows a partial view of the air storage tank body 1.

[0023] Specifically, the sealing mechanism 5 includes an electric telescopic rod 501, a support rod 502, a mounting plate 503, and a rubber plug 504. The electric telescopic rod 501 is fixedly installed on the lower surface of the cylinder 4. The support rod 502 is fixedly installed on the upper surface of the output shaft of the electric telescopic rod 501. The mounting plate 503 is fixedly installed on the upper surface of the support rod 502. The rubber plug 504 is provided on the upper surface of the mounting plate 503 at a position corresponding to the water leakage hole 3.

[0024] In this embodiment, the output shaft of the electric telescopic rod 501 drives the support rod 502 to move upward, which in turn drives the rubber plug 504 on the mounting plate 503 to move upward, so that the rubber plug 504 is inserted into the water leakage hole 3, thereby achieving the effect of sealing the water leakage hole 3. The upper surface of the electric telescopic rod 501 and the lower surface of the gas storage tank body 1 form a sealed structure.

[0025] Specifically, a through hole 10 is provided on the lower side wall of the cylinder 4 corresponding to the electric telescopic rod 501, and the diameter of the mounting plate 503 is half the inner diameter of the gas storage tank body 1.

[0026] In this embodiment, the through hole 10 meets the requirement that the output shaft of the electric telescopic rod 501 can pass through the lower side wall of the cylinder 4.

[0027] Specifically, the drainage mechanism 7 includes a solenoid valve 701, a Y-type filter 702, and a water outlet pipe 703, which are fixedly installed on the right side of the drainage pipe 6 from left to right.

[0028] In this embodiment, the solenoid valve 701 is opened, allowing the condensate at the bottom of the gas storage tank body 1 to flow into the cylinder 4, then into the drain pipe 6 through the cylinder 4, and then into the Y-type filter 702 through the drain pipe 6. The condensate is then discharged through the outlet pipe 703 on the right side of the Y-type filter 702, and the Y-type filter 702 filters impurities in the water.

[0029] Specifically, the control mechanism 8 includes a controller 801, a first liquid level sensor 802, and a second liquid level sensor 803. The controller 801 is installed on the front side of the gas storage tank body 1. The first liquid level sensor 802 is embedded in the side wall of the gas storage tank body 1 corresponding to the lower surface of the partition 2. The second liquid level sensor 803 is fixedly installed at the corresponding position on the lower inner wall of the gas storage tank body 1. The controller 801 is electrically connected to the first liquid level sensor 802 and the second liquid level sensor 803.

[0030] In this embodiment, when the first liquid level sensor 802 detects water, it feeds the information back to the controller 801. The controller 801 opens the sealing mechanism 5. After the sealing mechanism 5 completes the sealing, it opens the drainage mechanism 7. When the second liquid level sensor 803 detects no water, it feeds the information back to the controller 801. The controller 801 closes the drainage mechanism 7 and then resets the sealing mechanism 5 downwards. The controller 801 can open and close the first liquid level sensor 802 and the second liquid level sensor 803 and receive information.

[0031] Specifically, the controller 801 is electrically connected to the electric telescopic rod 501 and the solenoid valve 701.

[0032] In this embodiment, the controller 801 controls the opening and closing of the electric telescopic rod 501 and the solenoid valve 701.

[0033] Specifically, the heating mechanism 9 includes a heating plate 901 and a temperature sensor 902. The heating plate 901 is fixedly embedded in the lower side wall of the gas tank body 1 near the front and rear positions. The temperature sensor 902 is embedded in the lower side of the gas tank body 1 near the right side position. The heating plate 901 and the temperature sensor 902 are electrically connected to the controller 801.

[0034] In this embodiment, the temperature sensor 902 monitors the temperature at the bottom of the gas storage tank body 1. When the monitored temperature is lower than the set value, the information is fed back to the controller 801. The controller 801 then opens the front and rear heating plates 901 to heat the bottom of the gas storage tank body 1, effectively preventing the condensate from freezing.

[0035] During use, condensate inside the gas storage tank body 1 flows to the bottom of the gas storage tank body 1 through the drain hole 3 on the partition 2. The water level inside the gas storage tank body 1 is then monitored by the first liquid level sensor 802 in the control mechanism 8. When the first liquid level sensor 802 detects water, it feeds the information back to the controller 801. The controller 801 opens the electric telescopic rod 501 in the sealing mechanism 5. The output shaft of the electric telescopic rod 501 drives the support rod 502 to move upward, causing the support rod 502 to drive the rubber plug 504 on the mounting plate 503 to move upward, so that the rubber plug 504 is inserted into the drain hole 3, achieving the effect of sealing the drain hole 3 and preventing gas from overflowing from the gas storage tank body 1. After sealing, the controller 801 opens the solenoid valve 701 in the drainage mechanism 7, and the water inside the gas storage tank body 1 flows into the cylinder 4, then into the drain pipe 6, and then into the Y-type filter 702. The water outlet pipe 703 on the right side of the filter 702 discharges water, and the Y-type filter 702 filters impurities in the water. When the second liquid level sensor 803 detects no water, it feeds the information back to the controller 801. The controller 801 closes the solenoid valve 701 and resets the sealing mechanism 5 downwards, opening the drain hole 3 to continue storing water, thus increasing the automatic drainage function of the gas storage tank body 1. The installation and operation are simple and convenient, greatly reducing the tediousness of manual drainage, ensuring the long-term stable and reliable operation of the gas storage tank, and the automatic drainage will not affect the use of the gas storage tank body 1, improving the stability of the overall gas system. The temperature sensor 902 in the heating mechanism 9 monitors the temperature at the bottom of the gas storage tank body 1. When the monitored temperature is lower than the set value, it feeds the information back to the controller 801. The controller 801 opens the front and rear electric heating plates 901 to heat the bottom of the gas storage tank body 1, effectively preventing the condensate from freezing and ensuring smooth drainage.

[0036] In summary, this automatic drainage device for the air compressor's air tank adds an automatic drainage function to the main body 1 of the air tank. It is simple and convenient to install and operate, greatly reducing the tediousness of manual drainage, ensuring the long-term stable and reliable operation of the air tank, and the automatic drainage water will not affect the use of the main body 1 of the air tank, improving the stability of the overall air system, adding a heating function to the main body 1 of the air tank to avoid freezing, and ensuring smooth drainage.
