This invention provides an imidacloprid recrystallization refining and purification device, belonging to the technical field of purification devices. It includes a mixing chamber inner liner, with a mixing chamber outer shell fixedly installed outside the inner liner. The inner wall of the mixing chamber outer shell and the outer wall of the mixing chamber inner liner enclose a sealed heating chamber. A crystallization chamber inner liner is provided on the side of the mixing chamber outer shell, and a cooling crystallization tube is provided inside the crystallization chamber inner liner. An adaptive disturbance mechanism is provided inside the crystallization chamber inner liner. This adaptive disturbance mechanism can adjust the disturbance amplitude of the imidacloprid solution according to its crystallization degree. In this invention, by providing an adaptive disturbance mechanism, core components such as a float, a swinging linkage, a telescopic rod, and a stirring plate are integrated. The float senses the density change of the imidacloprid solution in real time at each crystallization stage, generates corresponding buoyancy based on the density, and achieves lifting and lowering. This, in turn, links the swinging linkage to swing around the slider on the limiting post, driving the telescopic rod to extend and retract radially along the sealed tube, ultimately achieving adaptive adjustment of the disturbance amplitude of the stirring plate.

This invention discloses a method for removing impurities from ferrous sulfate, a byproduct of titanium dioxide production, comprising the following steps: 1) taking ferrous sulfate and preparing a saturated solution; 2) adding dilute phosphoric acid, stirring thoroughly, and filtering to remove insoluble matter; 3) adding an appropriate amount of ammonia to the obtained solution, filtering, and evaporating the filtrate; 4) slowly stirring and cooling the remaining solution until the solution temperature drops to 10°C, centrifuging to obtain primary crystals and primary crystallization mother liquor; 5) dissolving the obtained primary crystals again and preparing a saturated solution, repeating steps 3) and 4) to obtain secondary crystals and secondary crystallization mother liquor; 6) dissolving the secondary crystals to prepare a ferrous sulfate solution, which can be directly used for the preparation of battery-grade iron phosphate. This method uses phosphoric acid, ammoniation, and recrystallization to remove impurities from ferrous sulfate through multiple processes. After impurity removal, the heptahydrate ferrous sulfate solid has high purity and low metal impurity content, and can be directly used for the synthesis of battery-grade iron phosphate after dissolution.

This invention discloses a die-cast water-electricity separation smart toilet instant-heating cleaning component, including a heating chamber, an upper cover, a lower cover, a heating element, a heating switch, a first thermostat, a second thermostat, a temperature sensor, and a controller. The heating chamber has an integrally connected partition plate dividing its interior into an upper flow channel and a lower flow channel. The heating element is embedded in the partition plate, with both ends exposed on the outside of the heating chamber. The operating temperature set by the first thermostat is lower than that set by the second thermostat. The heating chamber, partition plate, upper cover, and lower cover are all made of thermally conductive metal. This invention also provides a heating method for the above-mentioned die-cast water-electricity separation smart toilet instant-heating cleaning component. This invention can extend the water flow path, achieve sufficient heat exchange, completely separate water and electricity, and provide triple temperature control for power-off protection, improving heating efficiency and dry-burning tolerance.
