Abstract
The present invention belongs to the field of water processing technology, and proposes the method of utilizing artificial quartz sand to replace natural sand in purifying drinking water. Quartz ore suitable for being used as filtering material is thrice crushed, ball milled in a cylindrical ball mill to eliminate sharp angles, sieving graded and packed in different sizes. The processed quartz sand is used as filtering material in purifying system of water plant, and utilizing the artificial quartz sand to replace natural sand results in raised filtering effect, low cost and environment protection.
Description
Technical field
The invention belongs to water-treatment technology field, relate to a kind of method of utilizing synthetic quartz sand purifying drinking water
Background technology
At present, the filtering material that the water treatment plant uses is mainly derived from natural extra large sand, and the problem of existence is that natural sand is circular, and is little in the filtration middle section, poor filtration effect.Because of natural sand needs remote transportation, cause the cost height so cause the waterworks to purchase sand price height.Along with the town water demand strengthens, (30,000 tons of water factories are built at general county town of past can satisfy Urban water supply, existing then need build ten thousand tons of water factories of 8-10 and could satisfy water) the filtrate demand also heightens, cause the resource feedback weary, for obtaining natural extra large sand, begun to rob sea bed in some areas, ecotope is seriously damaged.Current, the main application of synthetic quartz sand is to satisfy cast steel moulding sand, and the oil kill-job is used and pipeline rust cleaning sandblast; The electroceramics roasting never is applied to the purifying drinking water field with industrial trades such as sand sand,
Summary of the invention
Weary in order to solve present natural sand resource feedback; poor filtration effect; because of natural sand needs remote transportation; cause problems such as waterworks production and operation cost height, the present invention proposes the method that the artificial quartz sand of a kind of usefulness substitutes the natural sand purifying drinking water, it is abundant that quartz mine is contained; can satisfy the needs of tap water filtering material fully; good filtration effect of the present invention, cost is low, helps the protection of ecotope.
Technical scheme of the present invention is: (1) at first selects hardness greater than HRC5, and density is greater than 2.5 gram/mm
3, wear rate is below 0.5%, percentage of damage is the quartz mine that the filtrate that meets purifying drinking water below 1% requires; (2), the quartz mine that will meet the filtrate requirement enters the one-level blade-breaking machine, carries out the one-level fragmentation, and the quartz sand ore is processed into the bulk that each length of side is 5-10mm; (3), enter two-stage crushing, with hammer mill the quartz sand ore is processed into the bulk that the length of side is 1-2mm; (4), enter three grades of fragmentations, with hammer mill the quartz sand ore being processed into each length of side is the 0.5-1.2mm bulk; (5), the quartz sand ore through three grades of fragmentations after, enter the roller ball grinding machine by belt conveyor, process with 20kg/min, eliminate the acute angle that exists on the polygon particulate state quartz sand ore; (6), enter screening plant, enter the hopper of different size through the quartz sand after the screening, finished product press the different size pack and is packed through the quartz sand of chamfering; (7), the granular quartz sand that will process puts into the filtering layer of purifying system of water plant as filtrate, finishes the purpose that synthetic quartz sand substitutes the natural sand purifying drinking water.
The invention has the beneficial effects as follows: utilize synthetic quartz sand to substitute the natural sand purifying drinking water, aboundresources is gathered materials on the spot, and uses on the spot.Reduce natural sand is transported to the north from south expensive freight charges, reduced the waterworks material cost, synthetic quartz sand is polygon, and bigger than natural rounded sand interception seston cross section, good filtration effect helps the protection of ecotope.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is a process structure synoptic diagram of the present invention.
Fig. 2 is a water treatment procedure structural representation of the present invention.
Among the figure, 1. one-level blade-breaking machine, 2. secondary hammer mill, 3. three grades of hammer mills, 4. belt conveyor, 5. roller ball grinding machine, 6. cleaning apparatus, 7. screening plant, 8. hopper, 9. filtering layer, 10. supporting layer.
Embodiment
With one-level blade-breaking machine 1,2, three grades of hammer mills 3 of secondary hammer mill, belt conveyor 4, roller ball grinding machine 5, cleaning apparatus 6, screening plant 7, hopper 8 connect successively.At first select hardness greater than HRC5, density is greater than 2.5 gram/mm
3, wear rate is below 0.5%, percentage of damage is the quartz mine that the filtrate that meets purifying drinking water below 1% requires; The quartz mine that filtrate requires that meets of exploitation is entered one-level blade-breaking machine 1, carry out the one-level fragmentation, the quartz sand ore is processed into the bulk that each length of side is 5-10mm; Enter two-stage crushing, the quartz sand ore is processed into the bulk that the length of side is 1-2mm with secondary hammer mill 2; Enter three grades of fragmentations, with three grades of hammer mills 3 the quartz sand ore being processed into each length of side is the 0.8-1.2mm bulk; The quartz sand ore through three grades of fragmentations after, enter the roller ball grinding machine by belt conveyor, process with 20kg/min, eliminate the acute angle that exists on the polygon particulate state quartz sand ore; Quartz sand through chamfering enters screening plant, and the quartz sand after the process screening enters the hopper of different size, and finished product is pressed different size pack packing; (7), the granular quartz sand that will process puts into as filtrate above the supporting layer 10 of purifying system of water plant, finishes the purpose that synthetic quartz sand substitutes the natural sand purifying drinking water as filtering layer 9.In the whole course of processing, dust removal installation 6 and the removal of contamination equipment that is located in the screening plant 7 are disposed quartzy sand dust and impurity.
