Description
Technical field
The present invention relates to the protective gear that ore slurry pump prevents impeller reversion in the course of the work, relate in particular to ore slurry pipeline and be transported to ore slurry pump ore pulp that terminal dehydrating station the enters underflow system ore pulp that backflows in the pump impeller reversion that causes and pipeline and return and in pump, deposit the protective gear hardening.
Background technique
Dehydration workshop, concentrate conveyance conduit terminus ceramic filter dewatering process adopts underflow concentration systems to process secondary ore pulp, concentrated ore pulp enters underflow pump inlet pipe by concentrated collection of deckered stock chest, by underflow pump outlet conduit, being transported to ore pulp distributes and to enter ceramic filter after bucket again and dewater, underflow pump dehvery lift reaches 40 meters, if in pump operation process because of termination of pumping or the termination of pumping of breaking down of working, ore pulp in a pipeline high position will form passage by the pump housing and flow back into deckered stock chest, this just forms underflow pump impeller reversal phenomenon and causes pump impeller to come off, the fault that recurrence pump generating pump damages.Pump soft packing seal parts leak because pump reversion causes sealing ore pulp simultaneously; there is above-mentioned fault; need to overhaul in time processing; cause underflow pump fault treatment more; dead time is longer; simultaneously ore pulp also can harden in underflow pump inside deposition, causes pump cannot normally start operation, so the protection in the time of a set of device that prevents underflow pump fault need to being set pipeline is backflowed automatically.
Summary of the invention
For above-mentioned technical problem; underflow pump impeller after the invention provides a kind of safe and reliable device and making to stop can backflow and can not reverse because of ore pulp; soft packing seal parts can seal failure; the inner ore pulp of extreme lower position underflow pump of underflow concentration systems can not deposit and harden; avoid underflow pump to break down; reduce troubleshooting work, solve producing the protective system of the pulp conveying pump of the problem that impacts.
For solving the problems of the technologies described above, the invention provides a kind of protective system of pulp conveying pump, it is characterized in that: comprise deckered stock chest, described deckered stock chest bottom connects underflow pump inlet pipeline, described underflow pump inlet pipeline two ends connect respectively deckered stock chest bottom and underflow pump, and described underflow pump inlet pipeline and joint, deckered stock chest bottom are provided with discharge valve and valve; Described underflow pump outlet port arranges underflow pump export pipeline, and described underflow pump export pipeline is connected with a ceramic filter minute ore deposit bucket, and a described ceramic filter minute bucket one end, ore deposit is provided with ceramic filter supply pipe; Between described discharge valve and valve, underflow pump inlet pipeline arranges backwash tube, and deckered stock chest backwash water valve is set on described backwash tube; Between described valve and underflow pump, underflow pump inlet pipeline arranges arm, and described backwash tube arranges underflow pump backwash water valve on described backwash tube; Described underflow pump import one side arranges air bag valve, on described air bag valve pipeline, tee and Flange is installed, and on described underflow pump outlet short circuit, air bag valve is set, and on described air bag valve pipeline, tee and Flange is set, and connects the pipeline that backflows between described threeway.
Working principle:
According to field position, in underflow pump import and export pipeline section, measure suitable size and block, DN 150 air bag valves are installed on flange, threeway and flange are installed, make welding underflow pump and import and export a section bypass return tube.Air bag valve source of the gas adopts ceramic filter air compressor to provide, and field by using DN15 common steel tube causes underflow pump scene from ceramic filter atmospheric control, imports and exports 4 air bag valves of pipeline source of the gas is provided for underflow pump.Guarantee sealing and control well pipeline leak detection; After all situations is normal, come into operation.
The present invention compared with prior art has following beneficial effect:
1., the present invention has eliminated after underflow pump is shut down and has prevented that underflow pump reversion and ore pulp deposition from hardening in underflow pump; must be by the repeated work of manually opening back-flushing flushing underflow pump pipeline in prior art thereby solved; in the course of the work simultaneously; the present invention can make the corresponding outlet of underflow pump and inlet not have precipitation; increase work efficiency; therefore, the present invention has reduced maintenance number of times and the maintenance outage time of underflow pump.
