Description
Technical field:
The utility model relates to thickener underflow conveyings and service technique field, and in particular to a kind of thickener underflow conveying
With examination and repair system.
Background technique:
Concentrator is to be widely used in hydrometallurgy, dressing plant, chemical industry based on the solid-liquid separating equipment of gravitational settling effect
Factory etc. needs the place of solid-liquid concentration and separation.
The clarified solution (overflow) that concentrator top generates is discharged by the annular chute at top, the underflow (solid particle of generation
Object enrichment) usually transferred out by pipeline connection Pulp pump.
Concentrator has irreplaceable role in dressing plant, and it is next process that main function, which is concentration and dehydration,
Offer condition.Concentrator needs to shut down once breaking down, it is impossible to receive the material of a process, entire dressing plant is dense
The upstream equipment of machine needs to shut down at once, influences the operating rate and production capacity in entire dressing plant, influences the economic effect in dressing plant
Benefit.
Pressure rake is one of failure of concentrator most serious and one of the accident of dressing plant's most serious, needed after pressure rake by
The material of entire concentration basin, which is cleaned out, to be handled, and then refilling water can just resume production, and this process usually requires 5~
10 days time seriously affected the overall operation rate and production capacity in dressing plant.
The blocking of underflow pump inlet duct is to lead to one of pressure rake common cause.As shown in Figure 1, traditional thickener underflow is defeated

Sequence, and usually have larger distance between underflow pumping plant and underflow discharge gate, duct length is usually 20~70m, this distance
Length depend on concentrator diameter.Underflow pump is typically configured to that 1 work 1 is standby, when the work in normal production pumps out
When existing failure, stand-by pump is switched to, and if the pipeline of stand-by pump blocks, stand-by pump cannot work, with solid in concentration basin
The continuous sedimentation of body particulate matter, underflow density is higher and higher, and bed height is higher and higher, and underflow cannot be discharged in time, will
Generate pressure rake accident.
Since the underflow pump inlet duct of this conventional arrangement is very long, once the valve of underflow pump discharge gate is not shut,
Inlet duct will block, extremely difficult dredging after blocking, it usually needs pipeline be dismantled cleaning, such case has hair at dressing plant
It is raw.
Concentrator usually requires setting underflow pumping plant and is used to place and overhaul underflow pump.Underflow pumping plant is generally arranged at ground
Under, the ground of underflow pumping plant needs the chamber absolute altitude below than concentrator lower, to guarantee the smooth inflow underflow pump of ore pulp.Underflow
The common depth of pumping plant is 10~15m of underground, and difficulty of construction is larger, and cost is very high, considerably increases the cost of entire concentrator,
Increase the investment in entire dressing plant.
