Abstract
A sedimentation prevention device of a large coal water slurry storage tank consists of a plurality of circulation communicated coal water slurry storage tanks, wherein a slurry inlet, a circulation slurry inlet and slurry outlets are simultaneously arranged on each coal water slurry storage tank; more than three slurry outlets are arranged at the bottom of each tank body, and at least one slurry outlet is connected with a screw pump through a circulation pipeline which is communicated with the slurry outlet of the adjacent coal water slurry storage tank; the circulation slurry inlet is arranged in the way of being higher than the slurry outlets, and is connected with the screw pump through the circulation pipeline which is communicated with the circulation slurry inlet of the adjacent coal water slurry storage tank; and the slurry inlet is externally connected with the same slurry inlet pipeline and is arranged higher than the circulation slurry inlet; and a plurality of blowing nozzles are also arranged in each coal water slurry storage tank. At least more than two slurry outlets are arranged on the same slurry outlet pipeline. Compared with the technical structure which only adopts mechanical agitation to prevent sedimentation in the prior art, the device can ensure the coal water slurry to be stably stored for a long time, the quality of the coal water slurry is further improved, and the tank cleaning cost is saved.
Description
Technical field
The utility model relates to COAL-WATER SLURRY TECHNOLOGY, especially refers to the structural development technology of coal water slurry storage tank.
Background technology
Coal water slurry is the mixture slurry that a kind of coal adds water.In coal water slurry,, the coal grain is suspended in the aqueous medium, and forms uniform colloid because of after the coal particle surface doping modification one deck hydration shell being arranged, forming the same fuel of similar heavy oil uses for burning, but the coal particle by gravity, the time one is long, also can produce precipitation separation.The general mechanical stirring device that adopts prevents precipitation.With stirring the structure that not only can destroy slurry, consumption of power is also very big as only.As the crucial storage facilities that the finished product in a slurrying base is starched, the science of seeking is suitable for, and economic anti-settler is very necessary.
The utility model content
At the weak point that prior art exists, the utility model provides a kind of large-scale coal water slurry storage tank to prevent settler.This device can be guaranteed coal water slurry storage steady in a long-term; Guarantee that the quality of starching in the coal water slurry jar is even, sell the slurry stable and consistent; Fortified water coal slurry slaking function further improves the coal water slurry quality; Prolong the clear jar cycle of large-scale storage tank, reduce useless slurry loss, energy-conservation clear jar of expense.
For achieving the above object, technical solutions of the utility model are:
The anti-settler of large-scale coal water slurry storage tank is made up of the coal water slurry storage tank that a plurality of circulations communicate, and is provided with stock inlet, circulation stock inlet and grout outlet simultaneously on described each coal water slurry storage tank; Described grout outlet is to be arranged at tank base more than three, has the circulating line connecting screw rod pump of a grout outlet by communicating with adjacent coal water slurry storage tank grout outlet at least; Described circulation stock inlet is higher than the grout outlet setting, and by a circulating line connecting screw rod pump that communicates with adjacent coal water slurry storage tank circulation stock inlet; The external same pulp-inlet pipe of described stock inlet road is higher than the setting of circulation stock inlet; Also be provided with a plurality of blow-out nozzles in each coal water slurry storage tank.
Have at least plural grout outlet to be arranged on the same pulp pipeline.
The usefulness of technique scheme is:
The anti-settler of the large-scale coal water slurry storage tank of the utility model is only to adopt on the technical pattern that mechanical agitation prevents to precipitate improved on the basis in prior art:
1. the tank body multiple spot dress slurry technical pattern that is provided with a plurality of grout outlets can in time evenly be extracted the jar prime cement out shipping, prevents that slurry deposit of a specified duration and precipitated at a distance.
2. the multiple spot air blowing technical pattern that is provided with a plurality of blow-out nozzles in the tank body can make bottom deposition slurry stir under the high pressure air effect and move to the center, makes slurry recover original slurry constructional feature rapidly, thereby keeps effect steady in a long-term.
3. to be provided with the jar prime cement extracorporal circulatory system technical pattern of external circulation line outward be to solve in case find bottom slurry concentration and viscosity after testing unusual increase phenomenon takes place to tank body, can't separate when equal with taking multiple spot dress slurry and multiple spot air blowing measure, just take bottom slurry circulation, the top measure, mechanical agitation in addition again, whole like this tank body all can obtain up and down evenly very soon, keeps stabilized conditions.
4. the whole slurry of mechanical agitation uniformity under beating action plays the effect of homophony slurry.
Description of drawings
Fig. 1 is two tank body plan structure scheme drawings (A is the coal water slurry flow direction) of the anti-settler of the utility model coal water slurry storage tank;
Fig. 2 is the anti-settler list tank body master TV structure scheme drawing (B is the coal water slurry flow direction) of the utility model coal water slurry storage tank.
The specific embodiment
Large-scale coal water slurry storage tank is as shown in Figure 1, 2 prevented settler, and it is made up of the coal water slurry storage tank 1,2 that a plurality of circulations communicate.Be provided with stock inlet 3,4 simultaneously on described each coal water slurry storage tank 1,2, circulation stock inlet 5,6 and grout outlet 71,72,73,81,82,83; Described grout outlet 71,72,73,81,82,83 is to be arranged at tank body 1 bottom more than three.As shown in Figure 1, have the circulating line 9 connecting screw rod pumps 10 of a grout outlet 73 on the coal water slurry storage tank 1 at least by communicating with adjacent coal water slurry storage tank 2 grout outlets 83.Described circulation stock inlet 5,6 is higher than grout outlet 71,72,73,81,82,83 and is provided with.As shown in Figure 1, the circulating line 9 connecting screw rod pumps 10 of the circulation stock inlet 5 on the coal water slurry storage tank 1 by communicating with adjacent coal water slurry storage tank 2 circulation stock inlets 6.Describedly advance to starch .3,4 external same pulp-inlet pipe roads 13 and be higher than circulation stock inlet 5,6 and be provided with.Also be provided with a plurality of blow-out nozzles 11,12 in each coal water slurry storage tank 1,2.Have at least plural grout outlet to be arranged on the same pulp pipeline.As shown in Figure 1, the grout outlet on the coal water slurry storage tank 1 71,72 is arranged on the same pulp pipeline 14.Same, the grout outlet 81,82 on the coal water slurry storage tank 2 is arranged on the same pulp pipeline 15.
Above embodiment only simply describes for explanation design-calculated of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, any change of being done on the technical scheme basis all falls within the utility model protection domain.
