Abstract

This invention relates to the field of hydraulic engineering. The purpose of the invention is to reduce the energy consumption for the supply of water from the settling pond by reducing head losses. The pulp line 1, located on the slope 2, produces pulp. As a result, a plunger zone 4 and a settling pond 5 are formed. Alluvium from the initial location of the slurry pipeline 1 is produced until the expansion of the plunger zone 4 above the water level in the settling pond 5 reaches the minimum permissible value. Then the specific pulp consumption is increased to the ply zone 4, as a result of which more solid phase of the pulp enters the settling pond 5, crimping it and displacing water to the highest mark with depth Nd. Water is produced by pump station 7. After the possibility of increasing the specific flow rate is exhausted the pulps extend the slurry pipeline 1 towards the settling pond 5 and lead to the alluvium in the same sequence, maintaining the water level in the settling pond 5 and the highest mark of depth HO, from where the clarified water is supplied to the consumer or into the water recycling system. 1 hp f-ly, 4 ill.

The invention relates to hydraulic engineering construction, in particular, to methods of washing structures, mainly tailings and hydraulic outlets.

The purpose of the invention is to reduce the energy consumption for the supply of water from the reformer pond by reducing the geometric head loss.

Figure 1 shows the filling phase of the storage; Fig. 2 is the same, when j displaces the settling pond to the maximum level by increasing the specific pulp flow rate; in fig „3 - the same, after the pulp production in the direction of the settling pond; in FIG. 4, the same, when filling the storage with different steepness of slopes.

The method is carried out as follows.

The pulpway 1 is connected to the storage (Fig. 1), it is located on the slope 2 and the pulp 3 is made 3 out of 25 of its end face. As a result, a plunger zone 4 and a settling pond 5 are formed. Alluvium from the initial location of the pulpway 1 is produced as long as the elevation h of the puffed zone 4 d (fig 2) above the level 6 of water in the settling pond 5 reaches the minimum allowable value determined according to the regulatory documents. The relationship between the specific pulp flow rate and the propelled ridge above the pond is determined by the following relationship:

jj, the ability to increase the specific consumption of the pulp 3 displaces the output of the pulp 3 (FIG. 3) by extending the slurry line 1 towards the settling pond 5 and injecting it in the same sequence, maintaining water level 6 in the settling pond 5 at the highest depth mark H from where the clarified water is supplied to the consumer or to the circulating water supply system,

1. A method of storing waste rock, including pulp extraction, formation of a settling pond, raising the water level in the settling pond and supplying clarified water to the consumer or to the circulating water supply system, in order to reduce the energy consumption for the flow of water from the settling pond due to the reduction of pressure losses, increase and maintain the water level in the settling pond at the maximum level in Rus by storing empty rocks by the area of the Rus river in the washing zone of the puddle area with the excess of the float above the water level at the same time, the inhaling is carried out with a specific flow rate, which increases as the length of the pipe increases, and after the possibility of  146548P The specific pulp flow rate shifts the rock mass in the storage facility, which has a pulp output in the direction of the pond slope sloped, and the sedimentation tank is stored.
