This utility model discloses an air filtration structure for a screw air compressor, relating to the field of air filtration technology. The air filtration structure includes a base, a filter assembly on the upper surface of the base, and a disassembly assembly on the top of the filter assembly. The filter assembly includes a cylinder fixedly mounted on the base, a protective spring fixedly mounted on the inner bottom wall of the cylinder, an adsorption mesh fixedly mounted on the top of the protective spring, a positioning ring fixedly mounted inside the cylinder, a filter mesh mounted on the top of the positioning ring, and a silicone ring fixedly mounted on the upper surface of the positioning ring. This utility model, through its filter assembly and disassembly assembly, avoids clogging of the filter components during use. It also allows for disassembly and cleaning of the filter structure during use, preventing interference with normal filtration operations and improving the ease of use of the structure.

This utility model relates to the field of pipeline installation technology and proposes a steel sand bucket support platform for pipeline installation, comprising: a sand bucket containing dry sand, a support platform with its bottom located inside the sand bucket, two lifting devices symmetrically arranged on both sides of the sand bucket, and a vertical guide device on the outer wall of the sand bucket. The support platform consists of a support base with a closed cavity and an arc-shaped support platform with a rubber pad on top, the arc surface matching the outer diameter of the pipeline. The lifting device includes a strut, a pressure rod, and a telescopic handle. One end of the strut is hinged to the bottom of the arc-shaped support platform, one end of the pressure rod is hinged to the unused end of the strut, the unused end of the pressure rod is fixedly connected to the telescopic handle, and the middle section of the pressure rod is rotatably connected to the sand bucket. When the pressure rod is pressed down, the support platform is lifted through leverage. Sand guide holes with sand-blocking bolts are provided on the side wall of the sand bucket. This device can adjust the support height, and the support platform can be quickly lowered after sand discharge, allowing for rapid transfer to the next work section, thus improving the stability and efficiency of temporary pipeline support.
