Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1, the present embodiment is a filling riser buffer device, which includes a base 6 and a buffer bin 2 mounted on the base 6, wherein the bottom of the buffer bin 2 is mounted on the base 6, the top of the buffer bin 2 is used to communicate with a feeding pipeline 1, and the lower side wall of the buffer bin 2 is used to communicate with a discharging pipeline 3. In this embodiment the base 6 is a concrete base for fixing the buffer bin 2 and reducing vibrations.

In particular, as will be understood by those skilled in the art, the width of the buffer bin 2 in this embodiment is greater than the inner diameter of the feed line 1.

Further, the bottom of buffering workbin 2 has the inclined plane to 3 direction slopes of discharging pipe, and 2 bottoms of buffering workbin are established to the inclined plane, and the ground paste of being convenient for flows, and the inclined plane adopts the thickening steel sheet to consolidate in this embodiment.

Furthermore, the bottom of the buffer bin 2 is lower than the joint of the discharge pipeline 3 and the buffer bin 2, so that the tailings at the initial filling stage are deposited at the bottom of the buffer bin 2 to form a tailing protective layer, and the impact and the abrasion of the slurry of the feed pipeline 1 (vertical pipe section) on the bottom of the buffer bin 2 are effectively reduced.

Further, this embodiment still includes valve 31, valve 31 is three way valve 31, and three way valve 31 has feed inlet 311, discharge gate 313 and drain 312, feed inlet 311 is used for communicating with buffering workbin 2, and discharge gate 313 is used for communicating with ejection of compact pipeline 3, drain 312 is connected with discharging pipe 5, discharging pipe 5's discharge end is used for communicating with accident pool 4.

Specifically, when the open state of the three-way valve 31 is as shown in fig. 2, the three-way valve 31 communicates the buffer bin 2 with the discharge pipe 3, and when the open state of the three-way valve 31 is as shown in fig. 3, the three-way valve 31 communicates the buffer bin 2 with the discharge pipe 5.

Further, this embodiment still includes liquid level observation device 7, the lower extreme of liquid level observation device 7 is used for communicating with buffering workbin 2, and the upper end of liquid level observation device 7 is flushed with the top of buffering workbin 2. The liquid level observation device 7 is made of transparent materials, and scales are arranged on the liquid level observation device 7.
