It may also contaminate the internal components of the production equipment, shortening the equipment's lifespan.

[0003] Traditional screw air compressors have many shortcomings: First, the intake filter components are mostly single filters, which can only filter large particles of impurities and cannot effectively remove fine dust and moisture in the air, making it difficult to meet the high requirements for air cleanliness and dryness in the production of texturing fibers; second, the oil-gas separation effect is limited, and the recycling rate of the separated lubricating oil is low, which not only wastes resources, but may also affect the quality of compressed air due to oil residue.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Example 1: As Figures 1-5 ,include: The base 100 has an air tank 200 fixedly installed on its top and an air compressor main unit 210 fixedly installed on its top. The air compressor main unit 210 has a male screw rotor and a female screw rotor that mesh with each other inside. The air compressor main unit 210 has an air inlet 211 on one side and an exhaust port on the other side. An air intake filter assembly is fixed on the outside of the air intake 211 and includes a filter housing 220. The filter housing 220 has a primary dustproof mesh 222 and a composite filter layer 223 arranged sequentially from the outside to the inside. An air intake grille is provided at the end of the filter housing 220. An oil-gas separation assembly is connected to a gas storage tank 200 via a second pipe 250, and includes a separation tank 300, which contains an oil-gas separation filter element.

[0020] The specific application scenario of this embodiment is as follows: The base 100 provides basic support for the entire equipment. An air storage tank 200 is fixedly installed on its top. An air compressor main unit 210 is further fixedly installed on the top of the air storage tank 200. When the male and female screw rotors inside the air compressor main unit 210 rotate, they draw in outside air through the air inlet 211 on one side. The air is compressed through the meshing and squeezing of the rotors. The compressed air is discharged from the exhaust port on the other side and temporarily stored in the air storage tank 200. To ensure clean and dry intake air, an intake filter assembly is fixed outside the air inlet 211. Air first passes through the intake grille at the end of the filter housing 220 to initially block large particles of impurities, then enters the filter housing 220. It then passes sequentially through a primary dustproof mesh 222 made of nylon woven mesh and a composite filter layer 223 containing a water-absorbing resin HEPA filter element with a filtration accuracy of 0.3μm, completing the filtration of fine dust and adsorption of water vapor, achieving deep air purification. The air storage tank 200... The compressed air containing a small amount of lubricating oil is temporarily transported through the second pipeline 250 to the separation tank 300 of the oil-gas separation component. The oil-gas separation filter element inside the separation tank 300 is made of glass fiber material with a filtration accuracy of 0.1μm, which prepares for the subsequent efficient separation of oil and gas to obtain oil-free compressed air.

[0021] Example 2: Figures 1-3 The bottom of the separator tank 300 is provided with an oil return port, and the top of the base 100 is fixedly installed with an oil pump 310. The input end of the oil pump 310 is connected to the oil return port through the first oil return pipe 320, and the output end of the oil pump 310 is connected to the lubricating oil chamber of the air compressor host 210 through the second oil return pipe 330.

[0022] The specific application scenario of this embodiment is as follows: The oil-gas separation filter element made of glass fiber with a filtration accuracy of 0.1μm inside the separator 300 separates the compressed air into oil and gas. The separated lubricating oil is collected at the bottom of the separator 300 under the action of gravity and flows out through the oil return port opened at the bottom. After the oil pump 310 fixedly installed on the top of the base 100 is started, its input end is connected to the oil return port of the separator 300 through the first oil return pipe 320, which draws the separated lubricating oil into the oil pump 310. Then, through the second oil return pipe 330 connected to the output end of the oil pump 310, the lubricating oil is delivered to the lubricating oil chamber of the air compressor host 210, which provides continuous lubrication for the meshing rotation of the male screw rotor and female screw rotor inside the air compressor host 210, realizes the recycling of lubricating oil, and reduces resource consumption and waste lubricating oil disposal costs.

[0023] Example 3: Figure 2 and Figure 5 A drain pipe 260 is fixedly connected to the bottom outer wall of the air storage tank 200, and a drain valve 261 is fixedly installed on the outer wall of the drain pipe 260. The output end of the air compressor main unit 210 is fixedly connected to the input end of the air storage tank 200 through a first air pipe 230. A controller 240 is fixedly installed on the top outer wall of the air storage tank 200, and a switch knob is fixedly installed on the front outer wall of the controller 240. The inside of the controller 240 is connected to the air storage tank 200 through a conduit. A pressure gauge 241 is fixedly installed on the top outer wall of the controller 240. The conduit inside the controller 240 is connected to a second pipe 250. An exhaust pipe 270 is fixedly connected to the output end of the separator tank 300, and a one-way valve 271 is installed on the outer wall of the exhaust pipe 270.

[0024] The specific application scenario of this embodiment is as follows: Compressed air discharged from the air compressor main unit 210 is directly delivered to the input end of the air storage tank 200 through the first air pipe 230, ensuring that the compressed air enters the air storage tank 200 for temporary storage efficiently and without leakage; a controller 240 is fixedly installed on the top outer wall of the air storage tank 200, and its internal parts are connected to the air storage tank 200 and the second pipe 250 respectively through conduits, which can monitor the air pressure data inside both in real time. The pressure gauge 241 fixedly installed on the top outer wall of the controller 240 displays the monitored pressure value intuitively. The operator can adjust the operating status of the air compressor main unit 210 according to the pressure displayed by the pressure gauge 241 through the switch knob on the front outer wall of the controller 240 to maintain the overall air pressure stability of the equipment; a drain pipe 260 is fixedly connected to the bottom outer wall of the air storage tank 200, and a drain valve 261 fixedly installed on the outer wall of the air storage tank 200 is a solenoid valve and is electrically connected to the pressure sensor. When the air storage tank 200 When the internal pressure is lower than the set value, the pressure sensor sends a signal to the drain valve 261, causing it to close automatically. This prevents a sudden drop in pressure inside the tank during the draining process from affecting production. When the pressure inside the tank is normal and draining is required, the drain valve 261 opens, allowing the water and impurities accumulated at the bottom of the air storage tank 200 to be discharged through the drain pipe 260, ensuring the cleanliness of the inside of the air storage tank 200. The clean compressed air that has completed oil-gas separation in the separator 300 is discharged through the exhaust pipe 270 fixedly connected to its output end. The one-way valve 271 installed on the outer wall of the exhaust pipe 270 can prevent the discharged compressed air from flowing back to the separator 300, ensuring that the compressed air is delivered unidirectionally and stably to the texturing fiber production process.

[0025] Example 4: Figure 1 and Figure 2The base 100 has four fixed feet 110 at its bottom corners, and the bottom of the feet 110 is equipped with anti-slip pads. The primary dust filter 222 has several layers, with the filter pore size gradually decreasing from the outside to the inside. The multiple layers of primary dust filter 222 are snapped into place inside the filter housing 220 by a fixing frame 221. The specific application scenario of this embodiment is as follows: Support legs 110 are fixedly installed at the four corners of the bottom of the base 100. The anti-slip pads on the bottom of the support legs 110 can increase the friction with the ground, improve the overall stability of the equipment, and prevent the equipment from shifting due to vibration of the production workshop floor or accidental contact by personnel, thus ensuring the operating accuracy of the equipment. At the same time, in the air intake filter assembly, the primary dust filter 222 has several layers with the filter pore size gradually decreasing from the outside to the inside, which can more efficiently filter impurities of different particle sizes in the air, further improving the cleanliness of the intake air. The several layers of primary dust filter 222 are installed inside the filter housing 220 by the fixing frame 221. The fixing frame 221 can be directly removed later to clean or replace the primary dust filter 222, simplifying the maintenance operation process and reducing the maintenance difficulty.

[0026] The working principle of this utility model is as follows: When used by those skilled in the art, the screw air compressor used for producing textured fiber products is based on the base 100. Outside air is first initially filtered through the air intake grille at the end of the filter housing 220, and then sequentially passes through a composite filter layer 223 consisting of a nylon woven mesh primary dustproof net 222 and a HEPA filter element containing water-absorbing resin (filtration accuracy 0.3μm) to complete purification and drying. It then enters the air compressor main unit 210 through the air inlet 211. The male and female screw rotors inside the air compressor main unit 210 mesh and rotate to compress the air. The compressed air generated is transported to the air storage tank 200 for temporary storage through the first air pipe 230. The controller 240 on the top of the air storage tank 200 monitors the air pressure between the air storage tank 200 and the second pipe 250 through a conduit and is displayed by the pressure gauge 241. The solenoid valve type drain valve 261 is electrically connected to the pressure sensor and automatically starts and stops according to the pressure inside the tank. The air is discharged through the drain pipe 260. Impurities are removed to maintain cleanliness and pressure stability within the tank; compressed air in the storage tank 200 enters the separator 300 through the second pipe 250. The oil-gas separator filter element, made of glass fiber with a filtration accuracy of 0.1μm, separates oil and gas. The separated lubricating oil is drawn by the oil pump 310 through the return port and the first return pipe 320, and then sent back to the lubricating oil chamber of the air compressor main unit 210 for recycling through the second return pipe 330; finally, the separated clean compressed air is discharged through the exhaust pipe 270, and the one-way valve 271 prevents backflow, ensuring a stable supply for the production of textured fiber products.
