Description

Seperator of ash and water

The utility model belongs to sedimentation the special equipment technical field of separating in the suspended solid particles from liquid.

A large amount of dust are handled large-scale sedimentation basin commonly used, vertical round clarification filtration, centrifugation etc. in the shaft kiln chimney of cement plant to the Ash Water Separator of product ash aqueous mixtures after dedusting now.The sedimentation basin floor space is very big, and investment is many, and post precipitation will produce secondary pollution with machinery or artificial treatment deposition dust; The said equipment is handled the dust moisture content height make after the Ash Water Separator, is the clay shape, transportation inconvenience.Thereby the Ash Water Separator of the product after the dedusting of cement plant ash aqueous mixtures handled, demand designing a kind of novel device urgently and solve this difficult problem in the production.

At the problems referred to above, the purpose of this utility model is to provide a kind of seperator of ash and water.In order to determine the degree of holding back of grey aqueous mixtures separating particles, the flow velocity of water during with definite the clarification behind clarification precipitation, vacuum filtration, deposits the dust water content below 14% after reclaiming according to the Stokes law.And, can control the deposition dust of various demand humidity by speed adjusting to control valve and scraper plate machine.The utility model is installed in the patent No. 94238057.6 cement in vertical kiln wet scrubber bottom end opening buck mixture outlet places, and reliable, effective, reduced investment, energy consumption are low.The utility model has solved the cement plant deduster and has reclaimed dust Ash Water Separator problem, in the hope of comprehensive utilization.The paper pulp that also can be used for coal washing, metallurgy, machinery, all kinds of wet dust removal Ash Water Separator of mine industry and papermaking simultaneously separates recovery.

The utility model is realized with following mode: it is installed in cement in vertical kiln wet scrubber bottom end opening buck mixture outlet place, feature is that it has tower body 5, this tower body 5 is made of up big and down small 2 cylinders that are connected that are positioned at same center line, and the tapered cone that is connected to become a time between 2 cylinders; The tapered secondary cone that becomes in tower body 5 bottoms; On the inner conical surface of cone, secondary cone ploughshare scraper 3 is housed all, this ploughshare scraper 3 is connected with the rotating shaft that is positioned at tower body 5 center lines, and running parts such as star reductor 9 are equipped with on the rotating shaft top.In tower body 5 top large cylinder lumen centers intake chamber 8 is arranged, its top is connected with water inlet pipe 17, and water dispenser 4 is arranged at intake chamber 8 bottoms, and the two communicates by mozzle 6; In secondary cone exit, tower body 5 bottom control valve 2 is housed, scraper plate machine 1 is equipped with in its underpart; In the described scraper plate machine 1 scraper plate 21 is housed, and constitutes transmission mechanism, also be communicated with formation vacuum chamber 11 with it by ejector 10 by chain 20 and sprocket wheel 19, guide wheel 18; Scraper plate in vacuum chamber 11 has filtering layer 12 21 times.Be with spilling water groove 7 outside tower body 5 upper end large cylinders, overflow water outlet pipe 15 is communicated with spilling water groove 7 and intermediate water tank 14, water pump 13 is housed and is connected with outlet pipe 16 in intermediate water tank 14 bottoms; Ejector 10 also is connected with intermediate water tank 14, outlet pipe 16 respectively when being communicated with vacuum chamber 11.

The utility model is novel, and design is unique, and cheap, effect is remarkable.Separate the degree of holding back of particle and the upflow velocity of primary water when it has determined that according to the Stokes law grey aqueous mixtures separates, the grey aqueous mixtures of post precipitation is by the suction filtration device of continuous motion formula, and the water content that makes the deposition dust is below 14%.And, satisfy the deposition dust in the comprehensive various technological requirements that reclaim in using by adjusting the deposition dust of the various demand humidity of the scraper plate machine speed of service and control valve outlet size control.The vacuum filtration technology that this seperator of ash and water is used the continuous motion formula still belongs to the first time at home.Technical have substantive distinguishing features and a progress.Solved the cement plant deduster and reclaimed dust Ash Water Separator problem, in the hope of comprehensive utilization.The paper pulp that also can be used for coal washing, metallurgy, machinery, all kinds of wet dust removal Ash Water Separator of mine industry and papermaking simultaneously separates recovery.

Now the utility model is described in further detail in conjunction with the accompanying drawings.

Fig. 1 is the utility model structural representation;

Fig. 2 one Fig. 3 is the structural representation of scraper plate machine 1; Wherein Fig. 2 is that the A of Fig. 1 is to view; Fig. 3 is the B-B section of Fig. 2.

With reference to Fig. 1, the utility model is installed in the patent No. 94238057.6 cement in vertical kiln wet scrubber bottom end opening buck mixture outlet places, tower body 5 diameter of phi D=3mm, high 3.5mm, wall thickness 8mm, the ash aqueous mixtures enters from water inlet pipe 17, enters Φ 800mm * 500mm intake chamber 8 through coarse filtration, enters water dispenser 4 through diameter of phi 300mm mozzle downwards.Because water dispenser 4 diameters are up-small and down-big to be the horn mouth shape, and the dust speed in the grey aqueous mixtures is reduced, keep tower body 5 interior water at the uniform velocity to make progress and flow, cause the inner conical surface precipitation of heavier dust to tower body 5 bottom secondary cones; Fine solid particle then upwards flows from water dispenser 4 bottoms, is precipitated to downwards when rising with water level on the inner conical surface of a cone of tower body 5.Star reductor 9 running parts such as grade are loaded on the intake chamber 8, the rotating shaft of its output passes through mozzle 6 to tower body 5 bottoms, axle connection ploughshare scraper 3, the slow speed rotation that rotating shaft changes with per minute 0.4, the dust that ploughshare scraper 3 will be deposited on the bipyramid face is scraped to the center discharge, enters scraper plate machine 1 by control valve 2.With reference to Fig. 2, Fig. 3, Fig. 1, scraper plate 21 is housed in the scraper plate machine 1, and constitutes transmission mechanism by chain 20 and sprocket wheel 19, guide wheel 18, also be communicated with formation vacuum chamber 11 with it by ejector 10; Scraper plate in vacuum chamber 11 has filtering layer 12 21 times; The dust that enters in the scraper plate machine 1 flows to filtering layer 12, because the continuous drawing vacuum, water sees through filtering layer 12 inflow vacuum chambers 11 and is drawn out of, and water is taken away by ejector 10.Again by chain 20 transmissions, the deposition dust water content that scraper plate 21 scrapes as raw material, is discharged from the outlet of scraper plate machine 1 below 14% behind vacuum filtration, enters the preceding mixer of balling-up again and mixes the back balling-up with raw material, has realized the dust recycling.By adjusting, can make the deposition dust obtain needed humidity to scraper plate machine 1 rotating speed and control valve 2 outlets.Water after separated enters intermediate water tank 14 from spilling water groove 7 through overflow water outlet 15, and then enters the cement in vertical kiln wet scrubber again through water pump 13, outlet pipe 16, has finished the recycling of water.The water of ejector 10 suction filtration vacuum returns the recycling that participates in water into intermediate water tank 14, outlet pipe 16.Whole process is carried out continuously, does not have secondary pollution.According to producing the supporting mensuration of 8.8 ten thousand tons of cement patent No.s, 94238057.6 cement in vertical kiln wet scrubbers per year, the utility model can reclaim dust 5000-8000 ton in 1 year, by 60 yuan of calculating of valency per ton, the annual saving is worth ten thousand yuan of 30-42, only can regain the cost of investment of a supporting seperator of ash and water in 4-5 month.
