Description
Technical field
Ore dressing field is the utility model is related to, particularly mill water recycles.
Background technology
With the continuous improvement of national requirements for environmental protection, environmental administration requires the industrial water of company as far as possible using industry
Backwater, therefore the industrial water of company is essentially all to send water back to workshop by two-stage pumping plant from Tailings Dam and use.
One-level pumping plant carries frequency converter by the pontoon in Tailings Dam and water is sent to secondary pumping station pond by water pump, due to two
Individual pumping plant is all to send water by the way of manual adjustment frequency for a long time relatively far apart, plus invisible pond liquid level because
This long-term overflow of water for serving pump pond returns to Tailings Dam, so using backwater cost more than using the new water in reservoir into
This is much higher.
By taking certain southern large ore enterprise as an example, the Tailings Dam of the enterprise is to build within 2013 the new large-scale mine tailing for workshop last person's ore deposit
Storehouse, ore deposit storehouse catchment area 17.25km2, the right bank slope gradient are steeper（35 °~50 °）, the left bank slope gradient is slightly slow（10 °~35 °）, storehouse
Interior average gradient 13.5%, Tailings Dam design accumulation absolute altitude is to 1140m, and corresponding tailing dam maximum height of dam is 160m, aggregate storage capacity
35480000 m3, the m3 of effective storage 29,090,000, one-level pumping plant pontoon are located at Tailings Dam bank, and the equipment on pontoon is mainly by three three
Three 160KW of water chestnut FR740 transducer drives motor, controlled by way of manually adjusting potentiometer water supply flow and
Pressure supplies water to the pond of secondary pumping station, because the discrepancy in elevation of Tailings Dam to secondary pumping station is larger, employee's two stage pump back and forth
The distance between stand farther out, therefore the liquid level in uncontrollable good secondary pumping station pond, the long-term overflow in pond is caused so that workshop is given birth to
It is very high to produce cost.
Utility model content：
