2results about How to "Reduce dust rate" patented technology

This invention relates to a method for synthesizing dust-free silica gel cat litter at the source. Its morphology and mesoporous structure can be controlled at the source according to usage requirements, belonging to the field of pet product manufacturing technology. This method uses sodium silicate and an acidic solution as raw materials. By controlling the pH, temperature, and reaction time during the gel synthesis stage, the density of hydroxyl groups and the pore structure of the silica gel surface can be controlled at the source. Further optimization of its mesoporous structure and surface properties is achieved through treatment in an alkali metal salt solution. This method eliminates the need for subsequent resin coating or chemical additives, simultaneously achieving dust-free, high-adsorption, long-lasting odor-locking, and structural antibacterial functions at the synthesis source. The resulting silica gel cat litter has low dust content, high water absorption, and strong adsorption capacity for odors such as ammonia. The production process covers the entire process from synthesis and modification to sorting and packaging, making it suitable for large-scale continuous production. It solves the problems of balancing performance and environmental protection, unstable quality control, and fragmented industrial chains inherent in traditional processes.

This utility model relates to the field of crushing technology for household appliance recycling, and more particularly to a crushing device for household appliance recycling with a dust removal structure, including a crushing component and a dust removal component; the dust removal component is provided on one side of the crushing component. This utility model uses a dust separation screen in the recycling hopper to screen the crushed material discharged from the crusher. Large particles accumulate and slide down the inclined dust separation screen, then are discharged and collected through the solid fragments collection pipe. Fine dust particles pass through the screening holes of the dust separation screen and, due to the suction of the blower, are blown into the blower along the first dust conveying pipe and then along the second dust conveying pipe into the interior of the filter bag. The filter bag filters and collects the dust in the airflow.
