The air inlet of the screw air compressor body is fixed with a bottom air inlet pipe, and a top air inlet pipe is arranged on the top of the bottom air inlet pipe. There are no less than two groups of air inlet components between the bottom air inlet pipe and the top air inlet pipe. The patent sets two groups of air inlet components between the bottom air inlet pipe and the top air inlet pipe, and a single group performs air filtering. When one group of air inlet components is disassembled and assembled, the controller controls the electromagnetic valve on the bottom air duct and the top air duct of the group to close, and controls the electromagnetic valve on the other group of bottom air duct and the top air duct to open.

[0014] The present invention provides a screw air compressor with a convenient mold replacement function. It has the following beneficial effects: (1) The invention ensures smooth air intake by cleaning or replacing filter plate one after the filter plate is pulled out, thereby reducing the load on the air compressor during operation, thereby reducing energy consumption, improving the efficiency of equipment operation, and preventing the filter plate from becoming dirty or blocked, resulting in insufficient air intake and causing system overload or shutdown.

[0015] (2) The invention can effectively remove pollutants in the oil by filtering impurities, thereby extending the service life of the lubricating oil and preventing the accumulation of impurities due to long-term use of the lubricating oil, which leads to a decrease in the quality of the lubricating oil. The impurities on the filter plate 2 can be scraped off by moving the scraper rod, so that the surface of the filter plate 2 can be kept clean, ensuring that the filtration channel is unobstructed, thereby maintaining an efficient filtration process and preventing impurities from accumulating on the filter plate 2 for a long time, causing the surface of the filter plate 2 to be worn or corroded, thereby shortening the service life of the filter plate 2. The impurities on the scraper rod are pushed into the collection box by the sliding rod for collection, ensuring that the impurities are collected in the collection box to prevent them from re-entering the filtrate and causing secondary pollution. In this way, the purity of the filtrate can be improved and the influence of impurities on subsequent processing processes or product quality can be avoided.

[0016] (3) The invention can effectively keep the lubricating oil in an ideal temperature range by taking away the heat of the lubricating oil during the flow of water, thereby ensuring the normal operation and lubrication effect of the air compressor. By starting the refrigerator and starting to cool, the temperature of the water inside the water pipe is reduced, ensuring that the water flow can reduce the temperature of the lubricating oil and keep the temperature of the lubricating oil at a moderate level, reducing the wear of the air compressor parts, extending the service life of the equipment, and reducing failures caused by overheating. The lubricating oil inside the oil tank is stirred by moving the fixed plate, ensuring that the heat in the lubricating oil can be dispersed more quickly, avoiding the heat from being concentrated in a certain part, thereby accelerating the dissipation of heat, helping to improve the heat exchange efficiency of the lubricating oil and allowing it to cool more quickly.

When the slide bar 138 moves, the inclined block 147 is pushed to start moving, and the movement of the inclined block 147 drives the fixed rod 146 to start moving. The movement of the fixed rod 146 drives the push block 148 to start moving.
