This utility model discloses an encoder-based joint output torque measurement structure, including a fixed component and a motor joint. The motor joint is mounted on the fixed component, and a large flange is installed at the output end of the motor joint. A first connecting shaft is provided inside the large flange, passing through the motor joint. The first connecting shaft and the large flange are an integrated hollow structure. A front bridging flange is connected to the outside of the large flange, and a second connecting shaft is connected to the inside of the front bridging flange. The second connecting shaft is embedded inside the first connecting shaft. A connecting rod is connected to the outside of the front bridging flange. A rear bridging flange is installed at the tail of the motor joint. A large encoder disk is rotatably connected inside the rear bridging flange, and a small encoder disk is rotatably connected inside the large encoder disk. The large encoder disk is fixedly connected to the first connecting shaft, and the small encoder disk is fixedly connected to the second connecting shaft. A control board is connected to the outside of the rear bridging flange. This utility model has the characteristics of long service life and low operating cost.

The invention provides a boiler device for waste heat recovery, which relates to the field of waste heat recovery and comprises a boiler body, and a tube bundle heat exchange mechanism and a rotary heat tube mechanism which are connected in sequence. The tube bundle heat exchange mechanism is provided with a first tube bundle arranged in the flue gas channel; a smoke inlet of the rotating heat pipe mechanism is communicated with a smoke outlet of the pipe bundle heat exchange mechanism, and a rotating shaft with a second pipe bundle and a built-in heat pipe is arranged in the rotating heat pipe mechanism. And the flue gas backflow mechanism communicates the flue gas outlet of the rotary heat pipe mechanism with the hearth through a backflow pipeline and a fan. The self-cleaning mechanism comprises a flow guide plate arranged on the inner wall of the shell, a scraping plate which is fixed on the rotating shaft and is in contact with the flow guide plate, and an ash bucket at the bottom. Efficient and lasting waste heat recovery is achieved through heat exchange combination of the rotary heat pipe and the pipe bundle; the self-cleaning mechanism automatically removes dust; the flue gas backflow mechanism regulates and controls low-temperature flue gas to return to the hearth, and deep energy recovery is achieved. The system integrates monitoring and safety mechanisms, operation controllability and stability are guaranteed, and the heat efficiency of the boiler is integrally improved.

The utility model discloses a kind of double-flow eye control structures of aluminium melting furnace, including furnace body, the bottom of furnace body is equipped with first flow eye and second flow eye, and the opening of first flow eye and second flow eye is equipped with flow eye nozzle, the outer wall surface of furnace body is built with flow channel, and flow channel is located at the outside of two flow eye nozzles, arc slot is arranged in the inner side of flow eye nozzle, and two vertical guide rods are welded in arc slot. Advantage: compared with traditional aluminium melting furnace, the double-flow eye control structure is designed by double-flow eye, when one of flow eye appears to be blocked or blockage structure fails, another flow eye can be quickly enabled to continue production, avoid shutdown maintenance, significantly improve production efficiency. Arc-shaped block cooperates vertical guide rod, gear rack transmission mechanism, can accurately control the degree of flow eye opening and closing, and then realize fine adjustment to aluminium liquid flow, solve the problem that aluminium liquid flow rate is too fast to control caused by traditional blockage plug blockage.
