The application discloses an engineering tire pattern structure with equal groove width, variable pitch, low noise and full wear period, and the like, and relates to the technical field of tires. The application breaks through the technical bottleneck of single performance, inconsistent performance of each pitch, uneven wear, poor structural reliability and low universality in the design of a traditional engineering tire variable pitch, and through integrated innovative design of equal groove width basic design+density differentiation matrix solid convex point+three-order universal pitch proportion, the application realizes the coordinated consideration of low noise, performance consistency, uniform wear and structural reliability, and is suitable for the use requirements of engineering tires in heavy load and multiple working conditions in all directions.

The invention relates to a high-precision wastewater filtering system, and relates to the technical field of wastewater filtering. The present invention; according to the technical scheme, the device comprises a precipitation assembly used for precipitating large particles and located in an A area on the upper right side of a frame; the magnetic separation assembly is used for adsorbing fine magnetic substances, is connected to one side of the water outlet end of the precipitation assembly through a pipeline, and is positioned in the area A; the upper part of the treatment component is filtered through micron-sized non-woven fabric, the lower part of the treatment component receives filtered wastewater, and the treatment component is arranged in the region B, is positioned at the bottom of the magnetic component and receives wastewater discharged by the magnetic component; the two groups of filtering tanks are positioned in the area C and are connected with the treatment assembly through a multi-stage centrifugal pump; the suction assembly is arranged in the treatment assembly in a floating manner; the oil skimming assembly is used for receiving the oil dirt sucked out by the suction assembly and filtering the oil dirt, sewage obtained after the oil dirt is filtered is discharged into the treatment assembly again, and the oil skimming assembly is located in the area A; and the oil content detector is arranged in the middle of the suction assembly.
