The present invention provides a plastic admixture for vacuum extrusion molding of ridged vanadium tailings and a preparation method thereof, belonging to the technical field of plastic admixtures. The plastic admixture of the present invention comprises 6 to 36 parts of fiber, 0.5 to 5 parts of water retaining agent, 0.3 to 36 parts of plasticizer and 0.5 to 1.2 parts of coupling agent. The plastic admixture of the present invention solves the problem that the ridged vanadium tailings have low plasticity and cannot be vacuum extruded, realizes the transformation of vanadium tailings into assembled plates by vacuum extrusion, and at the same time enhances the crack resistance and compression resistance of vanadium tailings after extrusion, realizes the comprehensive utilization of vanadium tailings, saves energy and reduces consumption, and turns waste into treasure; at the same time, it reduces the occupation of land resources by tailings storage, reduces the risk of environmental pollution and personnel safety hazards, and realizes green, energy-saving, environmentally friendly and resource-based solid waste utilization.

The invention discloses a circulating water mechanism for automobile cylinder cover processing, which comprises a separating box, a placing platform, a circulating water assembly and a cooling pipe, a plurality of water leakage holes are distributed on the placing platform, a separating plate is arranged in the separating box, the separating plate extends towards one side and is gradually inclined downwards, an inclined overflowing inclined surface is formed on the upper surface of the separating plate, and the water leakage holes are formed in the water leakage holes. A plurality of retention grooves are distributed in the overflowing inclined face, each retention groove is provided with a discharging assembly, a control component used for controlling the discharging assemblies is arranged in the separating box, and a collecting assembly connected with each discharging assembly is arranged in the separating box. And a guide plate for guiding cooling water to fall to the high position of the overflowing inclined plane is arranged in the separation box and located between the separation plate and the placement platform. The device has the following advantages and effects that green separation of cooling water and metal scraps can be achieved, so that the use cost of an enterprise is reduced, pollution is reduced, and green and environment-friendly development is achieved.

The present invention provides a light-assisted rechargeable zinc-air battery and a preparation method thereof, belonging to the technical field of metal-air batteries. The technical scheme adopted is: dissolving 2-methylimidazole in anhydrous methanol for ultrasound; placing copper sheet, Zn(NO3)2·6H2O and Fe(NO3)3·9H2O in anhydrous methanol for ultrasound; mixing the above two solutions, centrifuging, washing and drying to obtain FeCu-ZIF powder; dropping N-methylpyrrolidone into a mixture of FeCu-ZIF powder, carbon black and polyvinylidene fluoride, grinding into a paste solid, applying the paste solid on nickel foam, calcining, cooling to room temperature to obtain FeCu-ZIF photoelectrode; assembling the FeCu-ZIF photoelectrode and zinc electrode using a zinc-air battery device, i.e., obtaining a light-assisted rechargeable zinc-air battery. The battery of the present invention uses a FeCu-ZIF photoelectrode with a porous structure, a bimetallic active center and good conductivity on the surface, realizing the synergistic conversion of solar energy, electrical energy and chemical energy in one device, with low economic cost and high energy utilization efficiency.
