The utility model relates to the technical field of flow dividers, in particular to a cyclone separator for cleaning tail gas in anhydrous aluminum trichloride production, which comprises a cyclone separator body, a gas outlet pipe is arranged on the top surface of the cyclone separator body, and a gas inlet pipe is arranged at the upper part of the cyclone separator body; a dust collecting mechanism is arranged at the bottom of the cyclone separator body and comprises a collecting shell, a separating assembly and a dust collecting box, the top of the collecting shell is fixedly connected with a discharging port of the cyclone separator body, the bottom of the collecting shell is fixedly connected with the top face of the separating assembly, and the bottom face of the separating assembly is in butt joint with a box opening of the dust collecting box. The separation assembly is used for separating dust in the dust collection box from the cyclone separator body, dynamic sealing is achieved through the separation assembly, gas leakage and dust backmixing are avoided, the separation efficiency is improved, a detachable fixing structure of the dust collection box and the separation assembly supports rapid replacement, shutdown is not needed, and production continuity is guaranteed.

This utility model provides a hot-rolled strip pickling and uncoiling device and a steel production line, relating to the technical field of steel production. It includes a first uncoiling processing assembly, a second uncoiling processing assembly, a scale-breaking machine, and a corner-cutting shear arranged sequentially along the strip's travel direction. The first and second uncoiling processing assemblies each include a coiler, a clamping straightener, and a head-cutting shear arranged sequentially. The two coilers are arranged in parallel and symmetrically. The output strip end of the head-cutting shear in the first uncoiling processing assembly is connected to the coiler in the second uncoiling processing assembly via a transport channel. The head-cutting shear in the second uncoiling processing assembly is connected to the scale-breaking machine via the transport channel. The corner-cutting shear is fixed to the discharge side of the scale-breaking machine and is used to cut the edges and corners of the scaled strip. This solves the technical problem of long downtime and reduced throughput during coil changing in the prior art, achieving the technical effect of eliminating downtime, improving equipment utilization, and shortening coil changing time.

This invention relates to the field of coal mine tunneling machine technology, and more particularly to an intelligent navigation and positioning device for coal mine tunneling machines, comprising: a laser positioning mechanism, which has a housing fixed to the coal mine tunneling machine and a laser instrument disposed inside the housing, the front side of the housing having a lens for laser penetration; a lens protection mechanism, including an annular cover disposed on the front side of the lens and fixed to the housing, and a transparent film covering the front surface of the annular cover; a transparent film driving mechanism for driving the transparent film to move from left to right or from right to left against the front surface of the annular cover; and a transparent film cleaning mechanism for cleaning the transparent film. The navigation and positioning device of this invention can continuously and efficiently maintain the cleanliness of the laser navigation window, thereby ensuring the continuous operation of coal mine tunneling.

This utility model relates to a temperature-controlled tea processing and roasting machine, including a temperature-controlled chamber, of which two chambers are provided; it also includes a ventilation chamber disposed between the two temperature-controlled chambers, with a ventilation component inside the ventilation chamber, and a sliding component inside the temperature-controlled chamber. A roasting component is mounted on the sliding component, which is used to move the roasting component out of the machine. The ventilation component is used to transfer excess heat from the temperature-controlled chamber currently roasting to the other temperature-controlled chamber for preheating the tea. A heat recovery pipe is installed on the left side of the temperature-controlled chamber to recover excess heat from the preheating temperature-controlled chamber. A heat supply pipe is connected to the rear end of the temperature-controlled chamber, and a diverter plate is connected to one end of the heat supply pipe extending into the temperature-controlled chamber. This new model, through the symmetrical layout of the two temperature-controlled chambers, allows excess heat generated during high-temperature roasting in one chamber to be transported to the other chamber via the ventilation component for preheating the tea, reducing subsequent energy consumption, while simultaneously controlling the discharge of heat to stabilize the temperature.
