The utility model discloses a crushing device for recycling limestone tailings, and particularly relates to the technical field of recycling and crushing, the crushing device mainly comprises a feeding box, a supporting plate and a supporting ring, the supporting plate is positioned on one side of the feeding box, the supporting ring is welded on one side of the supporting plate and is close to the top of the feeding box, and a multidirectional discharging mechanism is arranged at the top end of the supporting ring; the multidirectional discharging mechanism comprises a plurality of supporting strips fixedly arranged at the top end of the supporting ring. The multi-directional discharging mechanism is adopted, the supporting ring provides supporting force for the supporting strips, the side buckets provide supporting force for the ring frame, the ring frame supports the reinforcing supporting buckets and provides supporting force for the reinforcing supporting buckets, limestone tailings needing to be recycled in the middle are guided into the vertical pipe along the reinforcing supporting buckets, and the limestone tailings are recycled. Limestone tailings in other directions enter the multiple side hoppers correspondingly, feeding and crushing are achieved from different directions, the discharging applicability is wider, and the discharging and crushing efficiency is greatly improved.

The invention relates to the technical field of curtain wall windows, and discloses a curtain wall window structure which comprises an outer shell, a baffle is fixedly connected to the inner wall of the outer shell, a handle is arranged on the inner wall of the side, away from the baffle, of the outer shell, an inner shell is fixedly connected to the inner wall of the baffle, and a mirror surface is fixedly connected to the surface of the inner shell. The number of the baffles is two, the two baffles are symmetrically distributed with respect to the surface of the shell, the number of the handles is two, and the two handles are symmetrically distributed with respect to the inner walls of the baffles. When the device is used and after a curtain wall window is arranged, in the telescopic component, when a window is pushed, a handle is pushed to drive a bearing to rotate, when the bearing rotates, a sliding block is driven to rotate on the inner wall of a sliding groove plate, when the sliding groove plate rotates, an elastic pulling ruler is driven to rotate, and the elastic pulling ruler drives an external thread rotating shaft to rotate; when the external thread rotating shaft operates, the internal thread rotating shaft is driven to operate through threaded connection.

The invention discloses a silicon bronze alloy product and a preparation method thereof, and relates to the technical field of silicon bronze alloy products. Comprising the following steps that raw materials including 3.0%-3.5% of Si, 1.0%-1.5% of Mn, smaller than or equal to 0.1% of Fe, smaller than or equal to 0.05% of Ni, smaller than or equal to 0.02% of Zn, smaller than or equal to 0.02% of Pb and the balance Cu are mixed, and a mixture is obtained; casting the mixture to obtain a cast ingot; the cast ingot is subjected to high-temperature annealing at the temperature of 700-750 DEG C, and a blank is obtained; performing thermal deformation treatment and cold deformation treatment on the blank, and performing low-temperature annealing at 250-300 DEG C to obtain a silicon bronze alloy product; the microstructure of the silicon bronze alloy product comprises a copper matrix and a second phase distributed on the copper matrix, and the second phase comprises a Ni2Si phase, a Mn2Si phase and a Fe3Si phase. The silicon bronze alloy with high strength, high elasticity, excellent wear resistance and corrosion resistance and good processability can be produced by strictly regulating and controlling the ratio of the materials and optimizing the preparation process.
