This invention relates to a crystallization apparatus for preparing lithium hexafluorophosphate, comprising: a tank body, a feeding device provided on the top surface of the tank body, and an array of heat exchange components provided on the inner wall of the tank body. The heat exchange components include several heat exchange plates disposed on the inner wall of the tank body and arranged along the length of the tank body. This apparatus can increase the heat exchange area and enhance the heat exchange efficiency, enabling the uniform and rapid precipitation of lithium hexafluorophosphate crystals, and achieving continuous production with simultaneous crystallization and scale prevention.

The invention relates to a machine head assembly and an air supply device, and relates to the technical field of air supply. The machine head assembly comprises a supporting part and a working part, the supporting part comprises a supporting frame, the supporting frame comprises a datum plane, and the datum plane is provided with a circle center A and an axis L1 penetrating through the circle center A; the working part comprises a shell, the shell is movably connected with the supporting frame and provided with an axis L2, the axis L2 and the axis L1 intersect at a point o, the point o and the circle center A do not coincide, and the working part can be controlled to do conical rotation along the axis L1 with the point o as the vertex and the axis L2 as the generatrix. The stability of the gravity center of the machine head assembly can be guaranteed, generation of alternating stress is effectively reduced, and the service life of the whole machine is prolonged.

The invention relates to the technical field of high-voltage iron tower grounding resistance monitoring, in particular to grounding resistance monitoring equipment for a high-voltage iron tower. Comprising a bearing frame, the bearing frame is fixedly connected with a U-shaped frame, the lower side of the U-shaped frame is provided with a net-shaped metal hose, the lower side of the net-shaped metal hose is fixedly connected with a connecting seat, the connecting seat is fixedly connected with a grounding resistance monitor, and the grounding resistance monitor is hoisted through the U-shaped frame, the net-shaped metal hose and the connecting seat. The acting force between the monitoring device and the high-voltage iron tower is relieved. The installation structure between the monitoring device and the high-voltage iron tower is reconstructed, flexible connection replaces an original rigid fixing mode, the acting force between the monitoring device and the high-voltage iron tower is relieved through the net-shaped metal hose, vibration energy input is weakened, alternating stress borne by electronic components is fundamentally reduced, and the reliability of the high-voltage iron tower is improved. And the long-term monitoring stability of the grounding resistance monitor in a complex environment is ensured.
