This invention provides a vacuum oil filtration device. The vacuum pump and vacuum pipeline create a vacuum in the oil storage chamber, achieving a negative pressure state. Since the pressure above the filter screen is atmospheric, higher than the pressure inside the oil storage chamber, the oil on the filter screen is forced through the atmospheric pressure, thus improving filtration efficiency. An oil return tank is located on the main section of the vacuum pipeline, allowing oil to fall into it as it flows along the vacuum pipeline. This prevents oil from continuing to move along the pipeline into the vacuum pump, thus preventing damage to the vacuum pump from oil corrosion during the evacuation process in the oil storage chamber, extending the pump's lifespan and reducing maintenance costs.

The utility model discloses a thick ingot spray cooling device for ferro-molybdenum production, which comprises a spray room and a steel rail arranged on a roadbed at the bottom of the spray room, a flat transport vehicle is arranged on the steel rail, and a first traction mechanism and a second traction mechanism are respectively arranged on two sides of the spray room. A U-shaped spraying component is arranged in the spraying room, and one end of the U-shaped spraying component is communicated with a cooling water supply mechanism. The utility model relates to the technical field of ferro-molybdenum alloy smelting, an existing ferro-molybdenum ingot spraying cooling system is improved, the semi-surrounding type U-shaped spraying component is additionally arranged in the spraying room, and the U-shaped spraying component is arranged in the spraying room. Therefore, the contact area between the spraying cooling water and the ferromolybdenum ingot is greatly increased, and the cooling efficiency is effectively improved; water flowing out of the steel tray is guided through the flow guide grooves, so that erosion damage of cooling water to a flat transport vehicle, a steel rail track and a steel rail roadbed is effectively prevented, the operation reliability of the device is improved, and the maintenance cost is reduced.

An underground non-negative pressure water supply device comprises a pressurized water supply unit which is covered with an isolation hood. The lower end face of the isolation cover is provided with a dismounting port communicated with the internal space of the isolation cover. The lower end face of the isolation cover is provided with a seat plate attached to the isolation cover, and the seat plate shields and seals the disassembly and assembly opening. The pressurized water supply unit is arranged on the upper surface of the seat plate; the seat plate and the lower end of the isolation cover are fixed through a fixing structure; the outer wall of the isolation cover is provided with a plurality of pipe guiding holes communicated with the inner space of the isolation cover. A sealing ring matched with the guide pipe hole is arranged in the guide pipe hole; and an inner sealing part attached to the inner wall of the isolation cover is arranged on the outer peripheral surface of the inner end of the sealing ring. The buried non-negative pressure water supply equipment not only can effectively prevent indoor space from being occupied, but also can guarantee that electrical elements are not damaged, and therefore the service life is effectively guaranteed.
