Technological method of clamping device of multi-position cross-shaft processing machine

The invention relates to a technological method of a clamping device of a multi-position cross-shaft processing machine, by adopting the cross-shaft V-shaped slot positioning technology, milling and drilling tools are mounted on four rotating main shafts, the rotating main shafts are fixed on a workbench which can move left, right, frontward and backward, by utilizing the movement of the rotatingmain shafts, four end surfaces of the cross-shaft are firstly simultaneously milled, then the workbench is automatically returned onto a central line of the V-shaped slot, the four main shafts are simultaneously near to the cross-shaft, and four central holes are drilled on the cross-shaft at one time, thereby completing the processing of the end surfaces of the cross-shaft and the central holes on one working procedure at one time. The technological process comprises the following steps of: sawing-forging-milling-drilling-turning a shaft neck-thermal treatment-shot blasting-grinding the shaftneck-defect detection-inspection-packaging and warehousing, thereby not only reducing the processing working procedure of the cross-shaft, reducing the work time and the cost, reducing the labor intensity, improving the processing working efficiency by nearly 10 times, and saving the energy consumption by more than 60%, but also ensuring the concentricity and the vertical degree of the cross-shaft, realizing high processing precision and high qualified rate of the cross-shaft product.

Method for directly carrying out innocent treatment on electrolytic manganese residues in filter pressing plate frames

Provided is a method for directly carrying out innocent treatment on electrolytic manganese residues in filter pressing plate frames. The electrolytic manganese residues treated through the method are filter cakes obtained after filter pressing in the filter pressing plate frames of a plate-and-frame filter press, and sodium dihydrogen phosphate, calcium oxide, magnesium oxide and polyacrylamide are included in a treating agent. The method comprises the steps that 1, the electrolytic manganese residue filter cakes in all the filter pressing plate frames are washed through solutions obtained by mixing the sodium dihydrogen phosphate and water; 2, after the magnesium oxide, the calcium oxide and the polyacrylamide are dissolved in filter liquor collected in the step 1, the electrolytic manganese residue filter cakes are washed again; 3, filter liquor generated in the step 2 is collected, the plate-and-frame filter press is loosened to unload the filter cakes, and the electrolytic manganese residues generated after the innocent treatment are obtained. According to the method, soluble manganese in the electrolytic manganese residues is fixed, meanwhile, soluble ammonia nitrogen in the electrolytic manganese residues is fixed, and compared with the prior art, the advantages in the prior art are kept, the defects in the prior art are overcome, and the total cost of innocent treatment on the electrolytic manganese residues is lowered.

Underwater terrain inversion method for coal mining subsidence ponding area by utilizing InSAR monitoring data

The invention discloses an underwater terrain inversion method for coal mining subsidence ponding area by using InSAR monitoring data. The method comprises the steps: firstly obtaining SAR images before and after the subsidence of a research area and DEM data before the subsidence of the subsidence area, and obtaining surface subsidence information after subsidence through employing the D-InSAR technology; solving a probability integral method parameter of a working surface according to the surface subsidence information and parameters such as working surface angular point coordinates, miningthickness and inclination angle; and finally, inverting the dynamic change of the underwater topography of the subsidence area and the final form of the underwater topography after stopping mining byadopting a model based on a probability integral method. According to the method, the InSAR data acquisition cost is low; the surface subsidence data obtained by the D-InSAR technology is high in precision and large in data volume; the parameter inversion is based on semi-measured data, a parameter inversion result is suitable for the research area, the underwater topography of a ponding area in the mining process of a working face can be inversed, the establishment of an amphibious composite ecosystem of the subsidence area is guided, and an important reference is provided for land utilization planning, land reclamation, ecological restoration and the like of the land surface of the subsidence area.
