2, automatic cleaning is realized, the labor intensity of worker's upkeep operation is reduced, improves operating environment, it is effective to improve
Slag stewing water supply operating rate；
3, compared with manual cleaning water pump, it is possible to reduce 1 worker, every 10,000 yuan of cost-saving of the water pump Spring Festival holidays or more.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the filter interior structural schematic diagram of the utility model embodiment 2.
Specific embodiment
The present invention will be further described with specific embodiment with reference to the accompanying drawings of the specification.In order to preferably chat
It states, to go deep into before steel tubing portions are, after being reversed.
As shown in Figure 1, the utility model embodiment 1 includes bracket 1, storage tank 2, filter 3, centrifugal pump 4 and pipeline.
The storage tank 2 is mounted on the top of bracket 1, scale treatment liquid is placed in the storage tank 2, by recirculated water
Water quality test and fouling sample examination, for the concrete condition of slag stewing water supply pump, the scale treatment liquid that is used in the present embodiment
For dilute hydrochloric acid.The liquid outlet of 2 lower section of storage tank is connected with pipeline, for connecting with exhaust outlet 51 on water pump 5.
The filter 3, centrifugal pump 4 are mounted in 1 lower shelf of bracket.For the ease of activity, the bracket 11
Bottom can be equipped with universal wheel.
3 inlet of filter is connected with pipeline, for being connected with the lower exhaust outlet of water pump 5 by liquid outlet valve 52
It connects.3 liquid outlet of filter is connected with centrifugal pump 4,2 inlet 22 of storage tank by pipeline sequence.
Non-return valve is installed at 2 liquid outlet 21 of storage tank, inlet 22.
When cleaning, by water pump 5 import and export flange position closing, closing mode can according to water pump respectively situation and
Fixed, the present embodiment is closed entrance by the way of stifled blind plate, that is, with flange pipe plug.Open the liquid outlet 21 of storage tank 2
Ball valve, dilute hydrochloric acid enter water pump 5, set low speed rotation for water pump 5, make it dissolve the dirt of water pump 5 impeller and internal junction, then
Liquid outlet valve 52 is opened, the turbid with scale residue is flowed into filter 3 and is filtered, the filtering after the separation of solid-liquid primary
Liquid is returned in storage tank 2 by 4 secondary separation of centrifugal pump, liquid, reenters self-cleaning circulation, reaches dilute hydrochloric acid recycling.
Being structurally characterized in that for embodiment 1 is simple, and manufacturing cost is low, the water pump system that flushing cinder recirculated water utilizes, due to its water
The comparison of ingredients of dirt is complicated, often composite deposition, can be by the Mg (OH) in composite deposition after dilute hydrochloric acid enters2、CaCO3It is heavy
It forms sediment through chemical reaction handling, scorification is discharged hardened scale therewith, and solid component ratio is higher in turbid effluent, passes through filtering
Device 3 and centrifugal pump 4 are separated by solid-liquid separation, the forfeiture of dilute hydrochloric acid be not it is very high, in general, water pump self-cleaning had recycled 2~3 hours both
It may be implemented to clean out.And for the slag-washing-out pump that noncirculating water utilizes, main ingredient is Mg (OH) in scale2、CaCO3
Precipitating, as self-cleaning recycles, dilute hydrochloric acid loses higher, cleaning later period MgCl2、CaCl2It largely retains in circulation fluid, equally
Water pump clearance time needs 8 hours or more of specification.
Therefore, in order to improve dilute hydrochloric acid availability, water pump clearance time, filter of the embodiment 2 for embodiment 1 are reduced
3 structures are improved.
As shown in Fig. 2, the filter 3 include shell 31, inlet 32, liquid outlet 33, steam (vapor) outlet 34, strainer,
Filter plate, heating device 37, feed opening and dislodger 39.From top to bottom be respectively equipped with inside the shell 31 upper filter screen 351, on
Filter plate 361, lower filter plate 362, lower filter screen 352, the strainer is stainless steel web plate, described the purpose is to filter solid sediment
Filter plate be plate filter core.There is heating device 37 between upper filter plate 361, lower filter plate 362, is specifically as follows acidproof electrothermal tube.
Both there is solenoid valve at the liquid outlet 33 of the filter 3, links with the liquid outlet valve 52 being mounted at water pump 5, that is,
It opens or closes simultaneously, processing time consistency of the dilute hydrochloric acid in the circulation time and discharge liquor in water pump 5 in filter 3.Institute
Stating 3 top of filter has steam (vapor) outlet 34, and steam (vapor) outlet 34 is connected with 2 inlet 22 of storage tank by pipeline sequence, and dilute hydrochloric acid is
Volatile acid can be sent back to hydrochloric acid and vapor in storage tank 2 together by heating.In prioritization scheme, the steam goes out
There is unidirectional condenser pipe between mouth 34 and 2 inlet 22 of storage tank.The feed opening is connected by the pipeline with check valve with feed pot
It connects, the feed pot is not shown in Fig. 2, and feed pot can be fed by gravity and be not necessarily to liquid pump.Feed content
Depending on scale treatment liquid and composition of scale, scale treatment liquid is dilute hydrochloric acid in the present embodiment, is MgCl for object2、CaCl2,
Therefore there is upper feed opening 381 above upper filter screen 351, Ca (OH) is added2, to remove MgCl2.Have above lower filter screen 352
Lower feed opening 382, Na is added2CO3, to remove CaCl2.There is the dislodger 39 with blowdown valve in the bottom of filter 3,
Its purpose is exactly to deposit Mg (OH)2Precipitating and CaCO3Precipitating.
Turbid enters shell 31 by inlet 32, and solid particle is trapped on upper filter screen 351, upper filter plate 361, lower filter plate
362 rates of filtration are slow, increase the evaporation time of hydrochloric acid in turbid, equally reduce the water impact for dislodger 39, favorably
In the sedimentation of precipitating.
It should be noted that the specific embodiment of the utility model is described in detail the utility model,
For those skilled in the art, it is carried out without departing substantially from the spirit and scope of the utility model various
Obvious change is within the protection scope of the utility model.
