Calibration technology for multiple structured light projected three-dimensional profile measuring heads

The invention relates to a calibration technology for multiple structured light projected three-dimensional profile measuring heads, discloses a technology for calibrating multiple structured light projected three-dimensional profile measuring heads in different directions, which can be used for the quick label-free measurement of an object profile projected by structured light, and belongs to the technical field of optical measurement. In the calibration technology, only a calibration object of a plane with a plurality of calibration patterns is required to be designed and is not required to be manufactured into a high-precision three-dimensional target with known geometrical relationships on all surfaces; and geometrical parameters among all planes of the calibration object can be obtained by a close-range photogrammetry technology to upgrade the calibration object into the three-dimensional target, so the difficulty of machining and maintaining the high-precision three-dimensional target directly is reduced. By utilizing the technology, multiple structured light projected three-dimensional profile measuring heads can be measured from different visual angles in a label-free mode, and point clouds scanned in different directions are unified to one coordinate system automatically, so error accumulation caused by splicing is avoided effectively, and the time of the three-dimensional appearance reconstruction of the object can be shortened.

Melting furnace slag quenching dry type granulation and sensible heat recovery generating system and method using same

The invention provides a melting furnace slag quenching dry type granulation and sensible heat recovery generating system and a method using the same and belongs to the technical field of steel metallurgy furnace slag treatment and complementary energy recovery. The melting furnace slag quenching dry type granulation and sensible heat recovery generating system provided by the invention comprisesa slag-receiving device, a high-pressure water-air pulverization furnace slag quenching and granulating device, a furnace slag slow-cooling device, a sensible heat recovery generating device and a waste gas purification treatment device. According to the invention, the melting furnace slag is quenched and granulated by utilizing the high-pressure water-air pulverization device, so that the melting furnace slag is rapidly cooled to be in a glassy state; and then through a water-cooled type vibration grid plate, the melting furnace slag in the glassy state is further subjected to heat exchange with cold air so as to facilitate the subsequent recovery of the sensible heat. By the system provided by the invention, the melting furnace slag is quenched and granulated, and the high-temperature sensible heat resource of the furnace slag is sufficiently recovered and is used for generation on the basis that the water activity quality of the furnace slag is not influenced.

Cooking utensil

The invention provides a cooking utensil. The cooking utensil comprises an outer pot, a temperature controller, an elastic part and a heating disc. Guide holes are formed in the outer pot, the temperature controller is put in the outer pot, supporting legs are arranged at the bottom of a shell of the temperature controller, and the supporting legs penetrate through the guide holes. The elastic part is arranged between the shell and the outer pot, and the upper end and the lower end of the elastic part abut against the shell and the inner bottom wall of the outer pot respectively. The heating disc is arranged in the outer pot and covers the temperature controller, a receding hole is formed in the heating disc, and the top of the temperature controller can protrude out of the receding hole.The supporting legs make contact with the guide holes tangentially, and the sizes of the cross sections of the guide holes are larger than those of the cross sections of the supporting legs. Accordingto the cooking utensil, the supporting legs make contact with the guide holes tangentially, and the sizes of the cross sections of the guide holes are larger than those of the cross sections of the supporting legs, it is effectively avoided that a main temperature controller greatly rubs with an outer pot in the moving process, so that the main temperature controller is jammed, thus, the problemof jamming of the temperature controller is conveniently and effectively solved, and the cooking utensil is simple in structure and beneficial for popularization.

Self-scrub buckling beam probe

A self scrubbing buckling beam contactor for contacting an array of pads positioned on a device under test is described. The contactor consists of three insulating dies: a top, an offset and a lower die separated from each other by an insulated spacer of variable thickness. Each die is provided with holes. The buckling beam has an array of flexible wires positioned substantially perpendicular to the dies, each of the flexible wires crossing a corresponding hole in each of the top, offset and lower dies to allow each wire respectively contact a pad of the device under test. By shifting the center of the hole of the lower die relative to the center of the offset die, the tip of the wire exits from the lower die at an angle with respect to the plane formed by the pads of the device under test. The exit angle of the wire tip is controlled by the relative displacement of the offset die relative to the bottom die, such that the exit angle of the tip of the wire at the bottom die changes when the probe wire is under compression. By applying a reciprocating motion to the tip of the wire contacting the surface of the device under test, a scrubbing motion is achieved that lowers the resistance between the pad of the device under test. In this manner, the tip of the wire cleans the surface of the pads and prevents contaminants from adhering to the tip of the wire.

Comprehensive utilization method of aluminum ash

The invention belongs to the technical field of comprehensive utilization of waste resources from the aluminum industry and specifically discloses a comprehensive utilization method of aluminum ash. According to the comprehensive utilization method of aluminum ash, metallic aluminium is extracted from aluminum ash through an ore grinding method; the aluminum ash obtained after aluminium extraction undergoes catalytic deamination; the aluminum ash obtained after deamination is mixed with alkali and granulation forming is then carried out; and the granulation product is sintered and the sintered product is finally dissolved out. By the above method, useful components in the aluminum ash can be recovered to the maximum; ammonia gas which has been ignored for a long time is effectively recovered; components such as aluminium oxide, villiaumite and the like are recovered and utilized to the maximum; pollution of aluminum ash processing to the environment is avoided; atmospheric dust pollution is avoided; atmospheric pollution is also avoided due to ammonia gas recovery; pollution of aluminum ash stacking to underground water and soil is avoided due to extraction and recovery of fluoride salt; and environmental safety during the treating process is guaranteed.
