This invention provides a fixed flipping system, relating to the field of automotive painting equipment technology. It includes a moving mechanism, a flipping mechanism, a flipping shaft, and an auxiliary draining mechanism. The moving mechanism comprises two fixed frames, two limiting tracks, a moving drive assembly, and two moving plates. Each limiting track is installed within a fixed frame, and the moving drive assembly slides within the limiting track. Both moving plates are connected to the moving drive assembly, and the flipping mechanism is mounted on the moving plates. Through overall angle adjustment and the arrangement of lateral and vertical shaking components, forces can be applied to the residual liquid from multiple physical dimensions. Gravity, centrifugal force, and multi-directional inertial force work together to effectively disrupt the surface tension of the liquid, "driving" and collecting residual liquid hidden in the dead corners and bends of complex structures, achieving near-complete draining and significantly improving the quality and safety of subsequent processes.

The invention provides a storage battery lead-calcium alloy deslagging agent formula and a preparation method thereof, relates to the technical field of storage battery manufacturing, and aims to solve the problems that a lead furnace needs to be used in multiple procedures during storage battery production and manufacturing, and lead slag formed after lead or lead-calcium alloy in the lead furnace is oxidized can cause raw material waste and solid pollution. Lead in the lead slag can be recycled by using a proper slag remover. The formula comprises the following raw materials in parts by mass: 4-6 parts of coke powder, 2-3 parts of graphite powder, 0.1-1 part of activated carbon, 3-4 parts of sodium lignin sulfonate, 1-2 parts of lead stearate, 1-2 parts of quartz stone powder and 2-3 parts of limestone powder. When a lead furnace runs, lead slag floats on the surface of a lead pool, lead in the lead slag can be recycled by pouring the deslagging agent of the formula on the lead slag and stirring at high temperature, the oxidation speed of calcium, tin and aluminum in alloy is reduced, the components of the lead slag are changed, the amount of the lead slag is reduced, solid pollutants are reduced, and enterprise cost and environmental protection pressure are reduced.

The application discloses a preparation method of silica nano-aerogel heat-insulating paper, which comprises the following steps: (1) covering a permeable membrane interlayer on the surface of each fiber paper; (2) preparing a silica aerogel prepolymer mixed solution; (3) compounding the silica aerogel prepolymer mixed solution with the fiber paper to obtain wet silica aerogel paper; and (4) performing solvent replacement, hydrophobic modification and drying on the wet silica aerogel paper. The aerogel paper is prepared by covering the permeable membrane interlayer on the surface of the fiber paper and applying gravity in the gel process, so that the problems of the brittleness of the aerogel itself, the low strength of the fiber material itself, the damage of the prepared ultra-thin aerogel paper (less than or equal to 0.3 mm) and the like are solved, the gel absorption amount of the fiber paper is effectively controlled, and the flatness, thickness and thickness size deviation of the aerogel paper are ensured; and the prepared silica nano-aerogel heat-insulating paper is flat in appearance and free of defects such as wrinkles, holes and cracks which affect use.

The application discloses a removal device and removal method for organic matters in uranium purification conversion wastewater, and belongs to the field of uranium wastewater recycling. The application solves the problem that a small amount of organic phase contained in residual liquid of raffinate wastewater generated in a uranium purification process reduces the adsorption effect of exchange resin, and leads to a substandard treatment result of the wastewater. The application comprises a pre-separation tank, a vacuum separator, a pre-filter, a polymer separator and an adsorption filter which are sequentially connected through pipelines. A sewage pipeline is connected to the inlet end of the pre-separation tank. The outlet end of the pre-separation tank is further connected to a waste oil collection tank. A discharge port is arranged on the adsorption filter. Through the removal device and removal method for organic matters in uranium purification conversion wastewater, the content of organic phase in the uranium-containing wastewater is reduced to below 1 mg / L, the adsorption effect of the exchange resin is avoided to be reduced by the organic phase in the uranium-containing wastewater, the adsorption effect of the exchange resin on uranium ions in the uranium-containing wastewater is improved, and the uranium content of the uranium-containing wastewater is discharged below a standard value.
