[0015] In order to further describe the utility model, the utility model of a pulp feeding buffer device is further described in detail below in combination with the drawings and examples.
[0016] The receiving box 2 above the bin body 1 is connected in communication with the feeding port 3 at the top of the bin body through an inclined feeding pipe 4, and the inner wall of the feeding pipe 4 is provided with a spiral grid 5, and the feeding grid 6 is arranged at the feeding port 3.
[0017] The lower part of the bin body 1 is a tapered shape with a large upper part and a small lower part, and the umbrella plate 8 is arranged above the discharge port 7 at the bottom of the bin body, and the umbrella plate is supported on the inner wall of the bin body through six supporting legs 9. The supporting legs 9 are angle steels or channel steels, which are uniformly distributed in the circumferential direction of the discharge port.
[0018] The periphery 81 of the umbrella plate 8 is circular, and the distance between the periphery 81 and the inner wall of the bin body is 20-30 cm. The height of the supporting leg is 50-100 cm, and the umbrella surface shape is processed by using 8 mm steel plate and laid on the top of the supporting leg.
[0019] The distance from the connection between the supporting leg and the umbrella plate to the periphery of the umbrella plate is 1 / 2-1 / 3 of the radius of the circular periphery 81 of the umbrella plate.
[0020] By increasing the spiral grid inside the feeding pipe and adding the feeding grid at the feeding port, and installing the umbrella plate above the tapered discharge port at the bottom of the bin body, the discharge port blockage and bin body wear phenomenon are prevented, and the installation and maintenance operation is facilitated, which can meet the production needs of the discharge operation.
[0021] The spiral grid is arranged inside the feeding pipe to slow down the flow rate of the pulp. The feeding grid is added to the feeding port to slow down the flow rate of the pulp. The pulp is dispersed on the umbrella plate, which effectively avoids the discharge port blockage.
[0022] The ore pulp enters the feeding pipe through the receiving box, the internal spiral grid slows down the flow rate of the ore pulp to avoid pipeline scouring, the ore pulp further slows down the flow rate through the feeding grid of the feeding port, the ore pulp enters the bin body and preferentially falls to the umbrella-shaped plate for buffering, the umbrella-shaped plate uniformly falls to the discharging port after buffering, and the device realizes normal operation of the discharging and buffering operation. In the device, the ore pulp falls uniformly, the ore pulp does not directly scour the bin body, wear of the bin body is avoided, and problems prone to occur in daily production, such as blockage of the material in the discharging port and wear of the bin wall, are solved.
[0023] The umbrella-shaped plate is uniformly distributed and fixed at the lower part of the bin body through the angle steel or the channel steel, the problem of collapse of the umbrella-shaped plate is solved, and normal production needs can be met.
[0024] Through the steel plate processed into the umbrella-shaped plate and the spacing reserved between the umbrella-shaped plate and the bin wall, the ore pulp is conveniently and uniformly fed into the discharging port, the umbrella-shaped plate also plays a certain buffering role, and the effect of uniform discharging and buffering is achieved.
