Description

Technical Field

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

[0002] In an air compressor system, the air tank is an indispensable core component, primarily serving three functions: first, storing compressed air to balance the compressor's output with the air consumption of downstream equipment, preventing frequent compressor start-ups and shutdowns; second, stabilizing compressed air pressure to reduce the impact of airflow pulsations on the equipment; and third, utilizing volumetric effects to allow the compressed air to cool naturally within the tank, causing water vapor to condense into liquid water, achieving preliminary gas-liquid separation and laying the foundation for subsequent purification. Therefore, the stable operation of the air tank directly affects the quality of the compressed air and the energy efficiency of the air compressor system. However, existing air compressor air tank drainage methods have the following drawbacks: Most gas cylinders are designed with manual drain valves, requiring operators to periodically open the valves to drain accumulated water. This method relies entirely on manual experience to determine when to drain, which not only increases labor costs but also makes it easy for excessive water to accumulate in the cylinder due to forgetfulness, negligence, or untimely operation. This can lead to problems such as internal corrosion of the gas cylinder and excessive moisture content in the compressed air, shortening the service life of the equipment and affecting the normal operation of downstream pneumatic tools.

[0003] Many gas tanks are equipped with automatic drainage devices that use a float-type structure. The principle is that the float controls the opening and closing of the valve by rising and falling with the water level. However, since compressed air often contains impurities such as oil and metal shavings, the float is easily stuck by these impurities, causing the valve to fail to close or open properly, resulting in continuous leakage or drainage failure. This makes the system unreliable and difficult to meet the requirements for long-term stable operation. Utility Model Content

[0004] The purpose of this invention is to provide an air compressor tank with an automatic drainage function to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: An air compressor tank with automatic drainage function includes a tank with an air inlet and an air outlet connected to its side. A pair of high-pressure resistant glass panes are embedded in the side of the tank and fixed to it with sealant. An infrared transmitter is mounted on the side of one of the high-pressure resistant glass panes, and an infrared receiver is mounted on the side of the other. The infrared receiver receives infrared rays emitted by the transmitter. The infrared transmitter and receiver work together to accurately detect the water level inside the tank, avoiding errors caused by manual judgment of drainage timing, achieving automatic drainage, and reducing labor costs. The high-pressure resistant glass ensures infrared light penetration for water level detection while withstanding the high pressure inside the tank. The sealant ensures the tank's airtightness and prevents leakage. A water outlet is connected to the side of the tank and located below the high-pressure resistant glass pane. The water outlet is electrically connected to the infrared receiver. This connection allows for automatic start and stop of drainage based on the water level signal, preventing excessive water accumulation that could lead to tank corrosion or excessive moisture content in the compressed air.

[0006] Furthermore, the bottom surface of the gas tank is provided with a conical cavity, and the interior of the gas tank has a longitudinal water outlet channel and an oblique water outlet channel, which are connected. The free end of the longitudinal water outlet channel is connected to the end of the conical cavity with the smaller radius. The water outlet component is a solenoid valve, which is connected to the free end of the oblique water outlet channel. The conical cavity can concentrate the accumulated water to the bottom, which is convenient for discharge through the longitudinal water outlet channel and the oblique water outlet channel, reducing water residue. The solenoid valve responds quickly and can be opened or closed quickly according to the electrical signal to ensure timely drainage and no leakage of compressed air.

[0007] Furthermore, a transistor amplifier circuit and a relay are electrically connected in sequence between the solenoid valve and the infrared receiver. The solenoid valve, infrared receiver, transistor amplifier circuit, and relay are powered by a second power supply, while the infrared transmitter is powered by a first power supply. The transistor amplifier circuit can amplify the weak signal from the infrared receiver, ensuring reliable operation of the relay, thereby controlling the solenoid valve and improving circuit sensitivity.

[0008] Furthermore, the side of the gas tank is provided with an air inlet, and the air inlet component includes a one-way valve that communicates with the air inlet. The free end of the one-way valve is connected to an air inlet pipe. The one-way valve can prevent the compressed air in the gas tank from flowing back to the air compressor, ensuring the gas tank pressure is stable, and at the same time protecting the air compressor from reverse pressure impact.

[0009] Furthermore, the gas tank has an air outlet on its side, and the air outlet component includes an air outlet pipe that communicates with the air outlet. The free ends of both the air inlet pipe and the air outlet pipe are connected to flanges. The air outlet pipe delivers the compressed air in the gas tank to downstream gas-using equipment. The flanges facilitate the sealing connection between the air inlet pipe, the air outlet pipe and the external equipment, ensuring a firm connection and preventing air leakage.

[0010] Furthermore, both the air inlet and outlet are located above the high-pressure resistant glass, ensuring that air intake and exhaust occur in the upper space of the gas tank, avoiding direct impact of airflow on accumulated water or interference with water level detection, and ensuring the accuracy of infrared detection.

[0011] Furthermore, the transistor amplifier circuit includes an NPN transistor and a current-limiting resistor. One end of the current-limiting resistor is connected to the output terminal of the infrared receiver, and the other end is connected to the base of the transistor. The collector of the transistor is connected to the coil of the relay, and the emitter of the transistor is grounded.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This air compressor tank with automatic drainage function effectively solves the problems of traditional manual drainage relying on manual labor and float-type automatic drainage being prone to jamming by combining infrared detection and solenoid valve control: the infrared transmitter and receiver accurately detect the water level, and the solenoid valve is automatically drained by the crystal triode amplifier circuit and relay driving, which is fast and not easily affected by impurities; the conical cavity and dedicated water outlet channel ensure that the accumulated water is completely drained, and the one-way valve and flange ensure the stable operation of the tank, which significantly improves the automation level and operational reliability of the air compressor tank, extends the equipment life and ensures the quality of compressed air.

[0015] 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.

[0016] Please see Figures 1-5 This utility model provides a technical solution: an air compressor tank with automatic drainage function, including a tank 1. An air inlet and an air outlet are connected to the side of the tank 1. A pair of high-pressure resistant glass 5 are embedded in the side of the tank 1, and the high-pressure resistant glass 5 and the tank 1 are fixed together with sealant. An infrared transmitter 6 is installed on the side of one of the high-pressure resistant glass 5, and an infrared receiver 7 is installed on the side of the other high-pressure resistant glass 5. The infrared receiver 7 is used to receive infrared rays emitted by the infrared transmitter 6. A water outlet is connected to the side of the tank 1. The water outlet is located below the high-pressure resistant glass 5. The water outlet and the infrared receiver 7 are electrically connected. When the air compressor is working, the compressed air enters the air tank 1 through the air inlet. The water vapor in the tank gradually condenses into liquid water and sinks. When the water level rises to the point of blocking the light path between the infrared transmitter 6 and the infrared receiver 7, the infrared receiver 7 cannot receive the signal due to infrared refraction. This triggers the water outlet to open and drain the accumulated water. After the water level drops, the light path is restored. The infrared receiver 7 receives the signal and controls the water outlet to close, completing the automatic drainage cycle.

[0017] As an embodiment of this utility model, the bottom surface of the gas tank 1 is provided with a conical cavity 11. The interior of the gas tank 1 is provided with a longitudinal water outlet channel 12 and an oblique water outlet channel 13, and the longitudinal water outlet channel 12 and the oblique water outlet channel 13 are connected. The free end of the longitudinal water outlet channel 12 is connected to the end of the conical cavity 11 with a smaller radius. The water outlet component is a solenoid valve 8, which is connected to the free end of the oblique water outlet channel 13. The accumulated water gathers into the conical cavity 11 under the action of gravity and flows into the oblique water outlet channel 13 through the longitudinal water outlet channel 12. When the infrared receiver 7 triggers the drainage signal, the solenoid valve 8 opens, and the accumulated water is discharged through the oblique water outlet channel 13. After the drainage is completed, the solenoid valve 8 closes to block the leakage of compressed air in the gas tank 1.

[0018] In one embodiment of this utility model, a transistor amplifier circuit and a relay are electrically connected sequentially between the solenoid valve 8 and the infrared receiver 7. The solenoid valve 8, the infrared receiver 7, the transistor amplifier circuit, and the relay are powered by a second power supply, while the infrared transmitter 6 is powered by a first power supply. After receiving a signal, the infrared receiver 7 outputs a weak electrical signal, which is amplified by the transistor amplifier circuit and drives the relay coil to be energized. The relay contacts close, causing the solenoid valve 8 to connect to the second power supply and open. After the water level drops, the infrared receiver 7 stops outputting signals, the relay coil is de-energized, the contacts open, and the solenoid valve 8 closes, completing the circuit control cycle.

[0019] As an embodiment of this utility model, the air tank 1 is further provided with an air inlet on its side. The air inlet component includes a one-way valve 3 connected to the air inlet. The free end of the one-way valve 3 is connected to the air inlet pipe 2. The compressed air generated by the air compressor enters the air tank 1 through the air inlet pipe 2 and the one-way valve 3. The one-way valve 3 opens under the action of air pressure. When the air compressor stops working or the air tank pressure is higher than the output pressure of the air compressor, the one-way valve 3 automatically closes to prevent the compressed air from flowing back.

[0020] As an embodiment of this utility model, the side of the gas tank 1 is provided with an air outlet 10, and the air outlet component includes an air outlet pipe 9 connected to the air outlet 10. The free ends of the air inlet pipe 2 and the air outlet pipe 9 are both connected to flanges 4. The compressed air in the gas tank 1 is transported to the downstream equipment through the air outlet 10 and the air outlet pipe 9. The flanges 4 are fixed to the air compressor and the air-using equipment by bolts to ensure that the gas flows in the closed pipeline and avoids leakage.

[0021] As an embodiment of this utility model, the air inlet and air outlet are both located above the high-pressure resistant glass 5. Compressed air enters from the top of the air tank 1, cools and separates the water inside the tank, and the water sinks to the bottom. The dry compressed air is output from the air outlet at the top. The two paths are separated and do not interfere with each other, ensuring the stability of water level detection and drainage process.

[0022] As one embodiment of this utility model, the transistor amplifier circuit further includes an NPN transistor and a current-limiting resistor. One end of the current-limiting resistor is connected to the output terminal of the infrared receiver 7, and the other end is connected to the base of the transistor. The collector of the transistor is connected to the coil of the relay, and the emitter of the transistor is grounded. The signal output by the infrared receiver 7 is input to the base of the transistor through the current-limiting resistor, which turns the transistor on. A current is formed between the collector and the emitter, which drives the relay coil to be energized. The relay contacts close to control the solenoid valve 8. When the input signal disappears, the transistor is cut off, the relay is de-energized, and the solenoid valve 8 is closed.

[0023] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
