This utility model discloses an easy-to-clean smoke exhaust valve, relating to the field of smoke exhaust valve technology. The utility model includes an U-shaped cleaning frame, inside which a valve body is fixedly installed. A movable filter assembly and a flushing and cleaning assembly are disposed between the U-shaped cleaning frame and the valve body. A collection assembly is provided on one side of the filter end of the movable filter assembly. This utility model drives the filter end via a drive end, allowing the filter end inside the valve body to continuously move into the U-shaped cleaning frame, while the filter end inside the U-shaped cleaning frame continuously moves into the valve body. During this process, the flushing and cleaning assembly washes and cleans the dust accumulated on the filter end. This arrangement ensures that the airflow rate of the valve body is not affected by dust and impurities accumulated on the filter end, and that only the drive end needs to be activated to clean the accumulated dust and impurities on the filter end.

The utility model discloses a residual cement paste separation type concrete waste recycled aggregate pretreatment device, relates to the technical field of concrete waste, and aims to solve the problems that a traditional concrete waste treatment mode is high in energy consumption, and cement paste is left on the surface of part of aggregate. The mud separating assembly comprises a servo motor, a power output shaft of the servo motor is connected with a driving gear through a coupler, the bottom end of the driving gear is movably connected with the front end of the separating barrel, the outer side of the driving gear is movably connected with a linkage gear ring, and the inner side of the linkage gear ring is fixedly connected with a telescopic pipe. The end, away from the linkage gear ring, of the telescopic pipe is fixedly connected with a separation ball barrel. The residual cement slurry separation type concrete waste recycled aggregate pretreatment device disclosed by the utility model has the technical effects that the concrete waste is fully turned and stirred, the surface slurry separation can be efficiently realized, and the treatment efficiency and quality are improved.

The application discloses an elevator safety detection system and method, which comprises a magnetic grid scale belt break detection device and a leveling detection device. The magnetic grid scale belt break detection device comprises a support assembly, a counterweight component and a belt break detection assembly. When the magnetic grid scale belt breaks, the counterweight component drives the belt break detection assembly to move to compress the elastic assembly. The leveling detection device comprises a leveling detection assembly, a guide sleeve and a valve core. When the valve core is separated from the leveling detection assembly, the leveling detection assembly can slide from a standby position to a working position. In the early stage of the magnetic grid scale belt break, the counterweight component can push the belt break detection assembly to move to compress the elastic assembly to buffer the impact formed by the counterweight component. In the late stage of the magnetic grid scale belt break, the leveling detection assembly slides to the working position, and the elevator detects whether the car reaches the leveling position through the leveling detection assembly to ensure efficient evacuation of passengers.
