The utility model relates to expansion joint glue injection device technical field, concretely is a kind of high-pressure glue injection device for elastomer expansion joint material.The device includes base, high-pressure injection cylinder being set on base, filling mechanism for conveying glue to high-pressure injection cylinder, piston is slidably arranged on the inner side wall of high-pressure injection cylinder, driving mechanism for driving the linear sliding of high-pressure injection cylinder is set on the base;High-pressure injection cylinder is connected with the tail end of conveying long tube, and the first valve is set in the head end of conveying long tube.The characteristics of the device are that by pushing piston, great pressure is applied to the glue in high-pressure injection cylinder, so that the glue overcomes its own gravity and viscosity, and is injected into the use position after climbing a large difference.The device has simple structure, can quickly realize the purpose of pouring elastomer material directly from under bridge to bridge joint, and meets construction demand.

The utility model discloses a kind of silicon powder recovery devices in industrial silicon furnace flue gas, including equipment base, separator tank, smoke inlet and gas outlet, the inside of the separator tank is movably connected with multiple groups of adjusting mechanism for changing flue gas flow rate, the adjusting mechanism includes fixedly connected on the inner side wall of separator tank fixed pivot, the fixed pivot is movably connected with spoiler through fixed link, and the spoiler is in conformity with the inner diameter of separator tank, the end of the spoiler is movably connected with piston;Through fixed link and the spoiler of pivot connection, and piston is movably connected with the end of spoiler and penetrates tank body, when flue gas quantity is larger and flow rate is too fast, tank pressure rises and pushes piston to move out, drives spoiler to rotate to tank wall, expands flue gas flow range to reduce flow rate, prolongs flue gas residence time, makes silicon powder fully settle.
