The utility model relates to the technical field of cotton fiber pretreatment equipment, and discloses a ginned cotton cleaning machine, which comprises a cotton collecting component, a cotton collecting component, a cotton collecting component and a cotton collecting component, the cotton collecting component comprises a housing and a dust cage rotatably arranged in the housing, the housing is provided with a ginned cotton inlet, and the ginned cotton inlet is lower than the horizontal plane where the central axis of the dust cage is located; the cotton stripping assembly comprises a cotton pressing roller and a cotton stripping roller, and the cotton stripping assembly is used for stripping lint cotton from the dust cage; the scutching assembly comprises a licker-in and an impurity removal knife, and the impurity removal knife is arranged on one side of the licker-in; the cotton brushing assembly is arranged on the other side of the licker-in. The ginned cotton inlet is lower than the horizontal plane where the central axis of the dust cage is located, and the ginned cotton has a long distance from the inlet to the cotton stripping assembly, so that the dust cage can collect cotton more uniformly, cotton is not prone to being blocked during cotton returning, manual cotton drawing is not needed, and efficiency is improved.

This invention discloses a high-temperature melting waste heat recovery device for radioactive waste residue, belonging to the field of calcining furnace technology. It includes a calcining furnace body, with a connecting assembly at the upper end of the furnace body. A gas guide pipe is located at the upper end of the connecting assembly, and a fan is fixedly connected to the surface of the gas guide pipe. An airflow regulating assembly is fixedly connected to one side of the gas guide pipe, and a filter assembly is fixedly connected to one end of the gas guide pipe. A recovery tank is fixedly connected to the lower end of the filter assembly, and a cylinder is fixedly connected inside the recovery tank. A liquid exchange pipe is located inside the cylinder, and an exhaust pipe is fixedly connected to one side of the cylinder. This invention, by setting up the filter assembly, enables the disassembly and installation of the filter screen, facilitating replacement or cleaning by personnel. The connecting assembly also ensures a secure connection between the gas guide pipe and the calcining furnace body, preventing the connection from loosening due to prolonged heating of the gas guide pipe.
