3results about How to "Reduce dust rate" patented technology

The windproof fabric production equipment comprises a main machine frame, a supporting unit used for supporting fabric and a negative pressure device used for detecting air permeability are arranged on the main machine frame, the negative pressure device is located in the middle of the supporting unit and located below the fabric, the negative pressure unit comprises a groove cavity, and air supplementing grooves are formed in the front end wall and the rear end wall of the groove cavity. The invention provides windproof fabric production equipment and a production process thereof, which can be used for carrying out continuous ventilation detection on fabric on the basis of not destroying the integrity of the fabric to obtain the air permeability of the whole fabric and ensure the detection accuracy, and spraying marks on unqualified areas, so that the unqualified areas can be subsequently traced, and the production efficiency of the windproof fabric is improved. And dust removal operation on the bottom surface is carried out while air permeability detection is carried out, so that the dust rate of the wound fabric is reduced.

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.

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.
