Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of buffer feed bin, especially to high viscosity fly ash buffer feed bin with anti-blocking performance. BACKGROUND

[0002] In the lane type strip filling mining paste filling system, fly ash is often used as filling aggregate. Fly ash is transported to the filling station sand bin by power plant, and then is grabbed by the bridge type grab crane to the buffer feed bin, and finally slides from the discharge port of the buffer feed bin to the belt feeder below the buffer feed bin, and is transported to the large belt after being weighed by the belt, and then enters the mixing tank.

[0003] However, due to the high viscosity (about 10% water content) and fine particle characteristics of fly ash, caking often occurs inside the buffer feed bin and at the discharge port. The caking inside the buffer feed bin causes poor flow of the material inside the buffer feed bin, resulting in blockage. The caking at the discharge port of the buffer feed bin causes arching at the discharge port of the buffer feed bin, further affecting the smoothness of the discharge, causing the fly ash to be discharged intermittently during the discharge process.

[0027] The utility model discloses a spiral stirring subassembly 4 can break the agglomeration formed at the discharge port of buffer feeder bin body 1, prevent fly ash from appearing arching phenomenon at the discharge port, ensure that fly ash can flow out from the discharge port smoothly, thereby avoided the problem of unsmooth or blockage of discharge port caused by agglomeration arching.

[0028] Through setting up the scattering subassembly 5, the fly ash in the buffer feeder bin body 1 can be effectively scattered, so that the agglomeration and blockage of fly ash in the buffer feeder bin body 1 are avoided, the smooth flow of fly ash is ensured, and the unsmooth or stagnation of discharge caused by accumulation is avoided.

[0029] Further, the spiral stirring subassembly 4 includes a spiral main shaft 41, which is rotatably connected to the inner bottom of the buffer feeder bin body 1 and located at the top of the discharge port.

[0033] Further, the lower surface of the horizontal movable slide rail 54 is provided with a sliding groove one 541, and the upper surface of the moving plate 55 is fixedly connected with a plurality of groups of pulley sets two 553 which slide in cooperation with the sliding groove one 541.
