The accompanying drawing explanation

Fig. 1 is the structural representation of existing vertical sand warehouse;

Fig. 2 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

The structural representation of existing vertical sand warehouse as shown in Figure 1, the vertical sand warehouse 1 that comprises vertical setting, feed pipe 4 is equipped with on the top in sand storehouse 1, sand storehouse 1 internal upper part is provided with bypass channel 2, the bottom of bypass channel 2 is provided with delivery port, and this delivery port is connected with an end of bleed off pipe 10, and the other end of bleed off pipe 10 communicates with reservoir, separate between bleed off pipe, separate between the sand storehouse.

Existing vertical sand warehouse tailings slurry directly enters into the sand storehouse from feed pipe, part coarse granule tailings is deposited to the Sha Cang settling zone, fine grained tailings and water are along with the liquid level that increases of inlet constantly rises, and while surpassing the top of bypass channel 2, start to enter in bypass channel 2, flow into bleed off pipe 10 by delivery port, along bleed off pipe 10, flow into reservoir; In the winter time, if when spillway discharge is larger, a large amount of water rapidly flows out by bleed off pipe 10, if spillway discharge is less, the water overflowed is interior slowly mobile at bleed off pipe 10, easily freezes, and causes bleed off pipe 3 frozen blocks, causes vertical sand warehouse not use.Tailing slurry directly enters into warehouse by feed pipe 4 simultaneously, large to the precipitation disturbance of tailings, even settled part tailings can be stirred to overflow, and this kind of situation is particularly serious when sand storehouse material level is higher.

Of the present utility model a kind of vertical precipitation sand storehouse as shown in Figure 2, comprise sand storehouse 1 and on feed pipe 4, sand storehouse 1 internal upper part is provided with bypass channel 2, the charging aperture 5 of feed pipe 4 is horn mouth, and is provided with reflecting plate 6 at the horn mouth place; Be provided with siphon bleed off pipe 3 in bypass channel 2.

Siphon bleed off pipe 3 tops are provided with by-pass valve control 7.It comprises two sand storehouses that are communicated with by communicating pipe 8, and communicating pipe 8 is positioned at the below of bypass channel 2, and communicating pipe 8 is provided with valve 9.

Bypass channel 2 bottoms do not have delivery port, and siphon bleed off pipe 3 enters in sand storehouse 1 and stretches into bypass channel 2 from bypass channel 2 tops, with bypass channel 2 bottom connections, do not touch, and siphon bleed off pipe 3 tops are provided with the work that siphon by-pass valve control 7 can Artificial Control siphon bleed off pipe 3.

During winter, the communicating pipe valve in two sand storehouses 9 is closed, two sand storehouses are separate, siphon by-pass valve control 7 is closed, the tailings slurry enters by feed pipe 4, from horn mouth 5, flow out, obstruction through reflecting plate 6 is uniformly distributed to surrounding, then the whole section along sand storehouse 1 rises, tailings sinks to the Sha Cang settling zone, and overflow water enters in bypass channel 2 when liquid level surpasses bypass channel 2 top, when the water inlet that the liquid in flowing into bypass channel 2 floods siphon bleed off pipe 3 also raises gradually, automatically form siphon, the overflow water in bypass channel 2 is discharged rapidly.During work, the syphon flow is swift and violent, and discharge capacity is large, and the amount of liquid that flows into bypass channel 2 hour, siphon destroys automatically, and cutout fast, has prevented the difficult problem of low discharge overflow water frozen block bleed off pipe, effectively improved the mobility of slurry in the sand storehouse, improved deposition efficiency simultaneously.
