This invention discloses a molten salt pump with a bearing cooling system, belonging to the technical field of high-temperature molten salt pumps. It includes: a pump body, a pump shaft, a frame, a bearing housing, a cooling device, and a support frame. The pump body is mounted on the frame; the frame is mounted on the top of the pump body, and the bearing housing is mounted within the frame. The pump shaft is rotatably connected to the bearing housing via bearings. The cooling device is installed inside the bearing housing, with multiple microchannel coils respectively fitted onto the outer surface of the bearing. A flywheel energy storage device is installed inside the bearing housing, driving ambient air to enter through the air inlet and generating a forced airflow that blows across the cooling end of the cooling device for heat exchange. The cooling end of the cooling device is connected to a cold air inlet pipe, which is connected to multiple microchannel coils, and all microchannel coils are connected to an outlet pipe. An outlet is provided at the bottom of the bearing housing, and the outlet pipe is connected to the outlet. This invention miniaturizes and integrates a compressor-free cooling device into the bearing housing for active phase change cooling, extending the lifespan of the molten salt pump.

This utility model belongs to the field of conical flask technology, and particularly relates to a seawater filtration conical flask, comprising: a flask body, wherein a valve is provided at the bottom of the flask body for discharging seawater from the bottom of the flask body, an elastic ring is bonded to the bottom of the flask body, the inner sidewall of the elastic ring has a recessed portion, and the outer sidewall of the elastic ring has an extension portion; a support ring, wherein a mounting groove is provided at the top of the support ring, the mounting groove is adapted to fit the elastic ring, and is used to limit the elastic ring, the inner sidewall of the mounting groove has a limiting groove, which is used to form a snap-fit ​​engagement with the extension portion; during the process of the flask body moving the elastic ring and the extension portion to the mounting groove, the extension portion is subjected to the squeezing force of the inner sidewall of the mounting groove, and can generate elastic deformation along the direction of the recessed portion. Compared with the prior art, this utility model realizes that the filtered seawater is discharged from the bottom, which facilitates the installation of the flask body and the support frame.
