The invention relates to a preparation method and application of a nucleating agent. The preparation method comprises the following steps: mixing solvent pure water, calcium hydroxide and fatty acid methyl ester sulfonate, and heating; dropwise adding hexahydrophthalic anhydride into the mixed solution, and after dropwise adding is completed, carrying out heat preservation reaction to obtain the calcium hexahydrophthalate. The product has excellent performance when used for thermoplastic resin such as polyolefin.

This utility model provides a reaction crystallization kettle for preparing cryolite from fluoride-containing wastewater, relating to the field of reaction crystallization kettle technology. It includes: a shell, a stirring device and a material distribution structure at the lower end of the shell, a wire mesh in the middle of the shell, and an ultrasonic generator at the upper end of the shell. The stirring shaft of the stirring device is hollow, with a first feed inlet at the lower end of the stirring shaft. The material distribution structure forms a second feed inlet on the lower side wall of the shell. The upper side wall and bottom wall of the shell are respectively provided with a mother liquor outlet and a crystal slurry outlet. This invention solves the problems of poor reaction efficiency and equipment scaling in the current process of preparing cryolite from fluoride-containing wastewater.

The utility model provides a kind of vertical flow modularization folded plate flocculation tank of water purification plant, including flocculation tank body, at least two groups of modularization folded plate components and at least two groups of buttress. Flocculation tank body is vertical flow structure, and perforated sludge discharge pipe is arranged in width direction at bottom portion;Modularization folded plate component is spaced apart and installed in pool body along vertical flow direction, and it contains folded plate piece, L-shaped connecting plate and lining plate, L-shaped connecting plate two ends are connected folded plate piece and lining plate respectively, and lining plate is connected pool body wall body by bolt;Buttress corresponding component is equipped with pool bottom portion, and pressure relief hole with rubber sheet is opened, and it is enclosed with folded plate piece to form raw water closed unit. The present application improves installation efficiency and quality by modularization prefabrication, and pressure relief hole prevents water pressure impact, and modularization design is convenient for maintenance, staggered arrangement folded plate piece optimizes flocculation effect, and it is suitable for raw water treatment of water purification plant, and can prolong equipment life, reduce operation and maintenance cost.

This utility model discloses a screening device for producing high-slag-erosion-resistant iron trough castable, specifically relating to the technical field of screening equipment. It includes a driving component for driving a screen frame to screen the iron trough castable. The driving component comprises two screws respectively located on both sides of the screen frame, with the screws externally fixed to the screen frame via a buffer component. A movable shaft is located at the bottom of the buffer component. This utility model uses a servo motor to drive the screws to rotate. The screws drive the movable shaft to rotate synchronously via a first pulley, a belt, and a second pulley. Thus, when the screws drive the moving seat to reciprocate the screen frame, the movable shaft drives a lever to repeatedly move a spring-limited connecting plate up and down. This causes the material on the screen plate to not only be pushed but also thrown up and fall freely due to the up-and-down movement of the screen plate, creating a compound vibration. This also increases the collision efficiency between the material and the screen frame, achieving the purpose of breaking up material agglomeration and preventing screen frame blockage.
