This utility model discloses a mixing device for producing sesame and peanut mixed sauce, comprising: a material tank, a feeding hopper fixedly connected to the top of the material tank, a discharging hopper fixedly connected to the bottom of the material tank, a stirring mechanism provided inside the material tank and above the feeding hopper, a valve mechanism provided at the bottom of the discharging hopper, and a grinding outer layer 1 on the inner surface of the feeding hopper; sesame and peanut raw materials are fed into the feeding hopper and enter the grinding feeding chamber formed by the grinding outer layer 1 and the grinding outer layer 2 on the surface of the inner grinding hopper. The motor drives the shaft to rotate, driving the inner grinding hopper to rotate, and the raw materials are ground while feeding into the material tank. The upper and lower anti-blocking strips provide double anti-blocking, reducing accumulation, ensuring smooth flow, and reducing the frequency of downtime for cleaning. After grinding, the raw materials enter the material tank and are mixed by multiple sets of stirring blades on the shaft, realizing continuous operation of feeding, grinding, and mixing. The grinding and mixing actions are achieved through the shaft drive of the same set of equipment, eliminating the need for separate grinding equipment and processes.

This invention discloses a single-pass submerged arc welding method for high-penetration fillet welds, comprising: cleaning the area to be welded before welding without beveling; rotating the submerged arc welding jig to a first predetermined angle with the horizontal plane, and placing the workpiece panel on the jig to achieve a near-ship-shaped welding position; adjusting the submerged arc welding torch vertically downwards, first aligning the submerged arc welding wire with the right-angle vertex of the T-shaped fillet weld, and then setting the wire offset to a second predetermined range; setting the submerged arc welding process parameters, and using single-pass submerged arc welding to weld the T-shaped fillet weld. This invention solves the welding problems of insufficient and unstable penetration depth in T-shaped fillet submerged arc welds without beveling, and can obtain reliable high-penetration welds; the submerged arc weld has a uniform and aesthetically pleasing appearance, eliminates the beveling process and associated costs, and significantly improves welding efficiency. This invention can be widely applied to the welding and fabrication of steel bridge components such as steel plate beam I-beams and steel tower medium-thick plate rib units.

This invention relates to the field of optical precision inspection, and particularly to a sub-aperture stitching inspection method based on a frequency-domain and spatial-domain collaborative strategy. The method includes: acquiring discrete phase data of the sub-apertures; constructing a continuous physical field model; performing coarse alignment of adjacent sub-apertures using frequency-domain phase correlation technology to obtain integer pixel displacements between adjacent sub-apertures; performing sub-pixel fine alignment using a numerical gradient method based on the continuous physical field model and a normalized cross-correlation function with an embedded geometric error culling operator; constructing a global robust energy functional for global optimization; solving for the zero-curvature pose under a floating reference, and then performing Gaussian gradient weighted fusion and adaptive orthogonal base surface reconstruction to obtain the full-aperture surface shape of the large-aperture optical element. This invention solves the problems of strong initial value dependence, displacement-tilt degeneracy, cumulative error warping, and sensitivity to outliers in traditional sub-aperture stitching inspection methods, achieving ultra-high precision and high robustness in the sub-aperture stitching inspection of large-aperture optical elements.
