Description

Technical Field

[0001] This utility model belongs to the field of screw compressor technology, and specifically relates to a connection structure between a screw compressor and an oil and gas cylinder. Background Technology

[0002] A screw compressor is a positive displacement machine that uses two meshing helical rotors to compress gas or transport fluids. It is widely used in refrigeration, compressed air, and hydraulic systems. Screw compressors (such as screw presses) are typically used in conjunction with an oil-gas separator to form a complete compressed air system. The screw compressor compresses air through a pair of meshing rotors. During this process, lubricating oil is needed for sealing, cooling, and lubrication. The compressed oil-gas mixture enters the oil-gas separator. The main function of the oil-gas separator is gas-liquid separation. Centrifugal force and a filtration device separate the lubricating oil from the compressed air. The separated lubricating oil is cooled and filtered before being recycled, while the clean compressed air is delivered to downstream air-consuming equipment. When a screw compressor (such as a screw press) is operating, it compresses air through the rotors and simultaneously draws in a small amount of water vapor from the environment, which mixes with the lubricating oil to form an oil-gas mixture. The compressed, high-temperature oil-gas mixture enters the oil-gas separator, where centrifugal force and filtration achieve gas-liquid separation. The separated lubricating oil is cooled and recycled, while the compressed air enters the downstream system. During compression, water vapor condenses into liquid water, which accumulates at the bottom of the oil-gas cylinder. Therefore, it needs to be drained periodically using an automatic or manual drain valve to prevent moisture from mixing with the lubricating oil and affecting its lubrication effect, or from entering the gas-using equipment and causing corrosion and contamination. Proper drainage management ensures efficient system operation and extends equipment lifespan.

[0003] Conventional drainage structures rely on valves such as angle valves for periodic manual drainage. This requires frequent inspection and manual control, making operation complex. Furthermore, forgetting to drain the water often leads to reduced screw compressor efficiency and accelerated wear. Therefore, it is necessary to develop a drainage-friendly structure to reduce screw compressor wear and minimize personnel requirements. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a screw compressor and oil-gas cylinder connection structure with active opening and closing exhaust and multiple control modes.

[0005] The objective of this utility model can be achieved through the following technical solution: A screw compressor and oil-gas cylinder connection structure, characterized in that it includes a compressor body, a compressor motor and a compressed air tank are respectively provided at both ends of the compressor body, a drain pipe is provided at the bottom of the compressed air tank, a water inlet pipe is provided at the end of the drain pipe, a ratchet control assembly is provided on the water inlet pipe, a rotating ratchet and a moving ratchet are provided on the ratchet, a plurality of guide blocks are provided on the moving ratchet, a limiting step is provided on the water inlet pipe, a sealing valve plate is provided at the end of the moving ratchet, a guide rod is provided on the sealing valve plate, an internal spline is provided on the rotating ratchet, a control motor is provided outside the water inlet pipe, a connecting shaft is provided at the end of the control motor, a spline shaft is provided at the end of the connecting shaft, and a guide hole is provided at the center of the spline shaft.

[0006] In the above-mentioned screw compressor and oil-gas cylinder connection structure, the drain pipe and the water inlet pipe are provided with two coaxial threaded holes. The threaded holes are provided with the top and bottom of the drain pipe. Liquid sensors are provided in the threaded holes, and both liquid sensors are connected to the control motor.

[0007] In the aforementioned screw compressor and oil-gas cylinder connection structure, a display panel is provided between the liquid sensor and the control motor, and the display panel is provided with two indicator lights.

[0008] In the above-mentioned screw compressor and oil-gas cylinder connection structure, the water inlet pipe is provided with an installation hole for installing the connecting shaft, and the installation hole is coaxially arranged with the internal spline.

[0009] In the above-mentioned screw compressor and oil-gas cylinder connection structure, the compressed air tank is provided with several connecting pipes, and the compressed air tank pipe is provided with two air inlet pipes, which are connected to the compressor body.

[0010] Compared with existing technologies, the connection structure between this screw compressor and the oil and gas cylinder has a ratchet structure on the water outlet. The rotation of the ratchet moves and squeezes the sealing valve plate under the guidance of the inclined plane, thereby opening the drainage passage. The guide rod on the sealing valve plate, in conjunction with the guide hole, can prevent the sealing valve plate from resetting incorrectly and causing slow air leakage. At the same time, this design can facilitate the installation and locking of the connecting shaft when the motor is installed or when it is manually controlled. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , 2 As shown in Figure 3, the connection structure between this screw compressor and the oil-gas cylinder includes a compressor body 2. A compressor motor 1 and a compressed air tank 4 are respectively located at both ends of the compressor body 2. A drain pipe 7 is located at the bottom of the compressed air tank 4, and a water inlet pipe 12 is located at the end of the drain pipe 7. A ratchet control assembly 10 is located on the water inlet pipe 12. The ratchet control assembly 10 has a rotating ratchet 21 and a moving ratchet 23. The moving ratchet 23 has several guide blocks 22. A limiting step 17 is located on the water inlet pipe 12. A sealing valve plate 24 is located at the end of the moving ratchet 23. A guide rod 20 is located on the sealing valve plate 24. The rotating ratchet 21... The device is equipped with an internal spline 18, and a pressure control motor 5 is installed outside the water inlet pipe 12. The end of the pressure control motor 5 is equipped with a connecting shaft 15, and the end of the connecting shaft 15 is equipped with a spline shaft 9. The center of the spline shaft 9 is equipped with a guide hole 11. When drainage is required, the ratchet 21 is rotated. The rotation of the ratchet causes the moving ratchet 23 to move into the compressed air tank 4 until the moving ratchet 23 contacts and squeezes the sealing valve plate 24 to open the passage. The high-pressure gas in the compressed air tank 4 carries water and sprays out to achieve drainage. The pressure control motor 5 makes the rotation of the ratchet 21 easier and can infinitely adjust the opening range of the passage.

[0017] Preferably, the drain pipe 7 and the water inlet pipe 12 are provided with two coaxial threaded holes 16. The threaded holes 16 are located at the top and bottom of the drain pipe 7. Liquid sensors 8 are provided in both threaded holes 16. Both liquid sensors 8 are connected to the pressure control motor 5. When the liquid sensor 8 at the top comes into contact with liquid, the pressure control motor 5 is started to rotate by an angle to open the drainage passage. When the liquid sensor 8 at the bottom loses liquid sensing, the motor continues to rotate by an angle until the ratchet on the ratchet disengages. The sealing valve plate 24 moves rapidly under the action of air pressure until the passage is closed.

[0018] Preferably, a display panel 13 is provided between the liquid sensor 8 and the pressure control motor 5. The display panel 13 is provided with two indicator lights 14, which correspond to the liquid sensor 8 and are used to indicate whether the liquid level in the drain pipe 7 has reached the standard for liquid discharge.

[0019] Preferably, the water inlet pipe 12 is provided with a mounting hole 19 for mounting the connecting shaft 15. The mounting hole 19 is coaxially set with the internal spline 18. When both indicator lights 14 are lit, but the motor does not start, the motor is determined to be faulty. The ratchet can be controlled by manually rotating a control rod similar to the connecting shaft 15 to release the liquid until both indicator lights 14 are turned off.

[0020] Preferably, the compressed air tank 4 is provided with a plurality of connecting pipes 6, and the compressed air tank 4 is provided with two air inlet pipes 3, which are connected to the compressor body 2.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document frequently uses terms such as compressor motor 1, compressor body 2, air inlet pipe 3, compressed air tank 4, pressure control motor 5, connecting pipe 6, drain pipe 7, liquid sensor 8, splined shaft 9, ratchet control assembly 10, guide hole 11, water inlet pipe 12, display panel 13, indicator light 14, connecting shaft 15, threaded hole 16, limit step 17, internal spline 18, mounting hole 19, guide rod 20, rotating ratchet 21, guide block 22, moving ratchet 23, and sealing valve plate 24, the possibility of using other terms is not excluded.
