The filtering mechanism comprises a water inlet pipe, a filtering box, a supporting frame, a supporting block, a filtering net, a fine filtering net and a drainage frame, the water inlet pipe communicates with the bottom of the water inlet pump, the filtering box communicates with the bottom of the water inlet pipe, and the supporting frame is fixedly connected to the left side of the filtering box; the left side of the support frame is fixedly connected with the left side of the inner wall of the concentrated nitrate brine solar pond. According to the utility model, the function of filtering the inlet water of the water inlet pump is added, so that the water inlet pump can filter a water source entering the water inlet pump, and the condition that the water inlet pump can convey some larger impurities into the concentrated nitrate brine solar pond is prevented.

A solar pool lamp includes a solar module and an illumination module. The solar module is electrically connected to the illumination module and supplies power to the illumination module. The solar module includes a solar module housing and a solar panel. The solar panel is disposed on the solar module housing. The illumination module includes an illumination module housing and an illumination lamp assembly. The illumination lamp assembly is mounted in the illumination module housing. The illumination module housing and the solar module housing are detachably connected. This application adopts a split structure, which allows users to easily replace illumination modules of different power or brightness. In addition, the solar power supply mode reduces the need for installing cables, plugs, and sockets, making the installation more flexible and convenient.

This invention discloses a solar pond and lithium extraction method for producing lithium carbonate concentrate, belonging to the field of lithium extraction technology from carbonate-type salt lake brine. It addresses the problems of low lithium carbonate precipitation rate and poor lithium deposition effect in existing technologies for lithium extraction from carbonate-type salt lake brine. The solar pond of this invention includes a pond body, comprising a bottom plate at the bottom and side plates on the side walls. The side plates are inclined relative to the horizontal direction, and their inner sides have multiple protruding main facets extending from the bottom to the top of the pond, with the top angle of each facet being an obtuse angle. The lithium extraction method of this invention involves injecting lithium-rich brine and fresh water into the pond body, allowing it to stand for several days to obtain a three-layered salt gradient solar pond: a brine layer, a salt gradient layer, and a fresh water layer. The salt gradient solar pond absorbs solar energy, gradually increasing in temperature, and precipitating lithium carbonate concentrate. This invention can be used for lithium extraction from carbonate-type salt lake brine.
