[0018] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments.

[0019] The present utility model provides a blocky calcium carbide conveying buffer device, as Figure 1As shown in the figure, it includes a raw calcium carbide silo 1. The raw calcium carbide silo 1 is connected to a feeder 2. The feeder 2 is connected to a vertical feeding pipe 11 through a pipeline. One port of the vertical feeding pipe 11 is connected to a crusher 3. The other port of the vertical feeding pipe 11 is provided with a flange cover. A circular through-hole is opened on the side wall of the vertical feeding pipe 11. The circular through-hole is communicated with an inclined feeding pipe 6. A first through-hole is opened at the port of the inclined feeding pipe 6 close to the vertical feeding pipe 11. The first through-hole is communicated with a vertical pipe. The other port of the vertical pipe is provided with a blind cover 4 for the vertical feeding pipe. A second through-hole is opened on the side wall of the inclined feeding pipe 6 close to the first through-hole. The second through-hole is communicated with an inspection pipe 12. The other port of the inspection pipe 12 is provided with a flange cover. The inspection pipe 12 is arranged on the right side of the vertical pipe. The opening direction of the inspection pipe 12 is opposite to that of the vertical pipe; As Figure 2 As shown in the figure, an inclined pipe baffle 5 is welded at the port of the inclined feeding pipe 6 close to the pipe port of the vertical feeding pipe 11. The inclined pipe baffle 5 is an arc-shaped plate. The included angle between the inclined pipe baffle 5 and the inclined feeding pipe 6 is 90°. The other end of the inclined feeding pipe 6 is connected to an inclined material cleaning pipe 7. One port of the inclined material cleaning pipe 7 is a blind end. The other end of the inclined material cleaning pipe 7 is connected to a drum screen 9. The drum screen 9 is connected to a fine material silo 10. The crusher 3 and the drum screen 9 are jointly connected to a mixed material bucket elevator 8. The included angle between the inclined feeding pipe 6 and the vertical feeding pipe 11 is 110° - 125°. All the blind covers 4 adopt flange covers.

[0020] Among them, the inclined pipe baffle 5 is laid along the inner wall of the pipeline. When a part of the calcium carbide in the vertical feeding pipe is at the blind cover 4 of the vertical pipe, when feeding again, the massive calcium carbide fed by the inclined material cleaning pipe 7 and the vertical feeding pipe 11 collides with the calcium carbide at the blind cover 4 of the vertical pipe, rather than directly colliding with the pipeline, which improves the service life of the pipeline elbow; The vertical feeding pipe 11 is welded with the inclined feeding pipe 6. The included angle between the vertical feeding pipe 7 and the inclined feeding pipe 6 is 125° (the angle should not be < 110°), which effectively buffers the direct impact of the vertical feeding pipe on the pipe wall. The inclined feeding pipe 6 is welded to the feeding pipe port of the crusher 3. The inclined pipe baffle 5 is welded at the port of the inclined feeding pipe 6 close to the pipe port of the vertical feeding pipe 11. The shape of the inclined pipe baffle 5 is a radian shape. The height h of the inclined pipe baffle 5 is 30 mm (the height of the inclined pipe baffle is generally controlled at 2 / 3 of the diameter of the calcium carbide particle size). The radian included angle a of the inclined pipe baffle 5 is 90°. The calcium carbide is buffered at the inclined pipe baffle 5 and the inclined feeding pipe 6. When feeding continuously, the calcium carbide contacts the buffered calcium carbide, reducing the friction of the massive calcium carbide on the bottom pipe wall and improving the service life of the inclined feeding pipe 6.
