The technical scheme that solves above-mentioned task is: the siphoning installation that a cover is made up of siphon box, siphon pipe connecting, siphon destructing tube and siphon rising pipe valve is installed in air flotation pool, the siphon box of this device is installed in the top of air supporting pool wall, its top edge is no more than the highest retaining height of air flotation pool, and the feed-water end of siphon pipe connecting is connected with the water-supplying chamber of air flotation pool or water output duct.In addition, above reactive tank, the swash plate that the upper end tilts to the sludge sump direction has been installed also.
Automatically the air supporting mud discharging device has been compared following advantage with the air supporting mud discharging device of the employing mud scraper that generally uses at present:
(1) simple structure, cost is low.
As being example for 10 cubic metres air flotation pool per hour to handle the water yield, the about 1000-1500 of a mud scraper unit, as long as the air supporting automatic sludge discharger is with a small amount of sheet material, pipeline and valve, and need are 120 yuan altogether, are equivalent to 1/10 of mud scraper.Owing to do not have mechanical drive, keep in repair simple yet.
(2) without any need for power, running expense is low.
Per hour be that 10 cubic metres air flotation pool is an example to handle the water yield still, the power of motor of a mud scraper is 0.75 kilowatt, as one day 24 hours moving continuously commentaries on classics, wants 18 kilowatts of power consumptions every day, adopts this device without any need for power.
Because air supporting mud discharging device cost is very low automatically, not only newly-built equipment can install with this, and it also is reasonable and feasible having built and having used this device fully instead, because can reduce daily running expense, as the nationwide can both do, the electricity of saving will be a numeral greatly.
(3) purifying water effect of air flotation pool is better.
The air supporting automatic sludge discharger is without any mechanical shock, and the come-up mud of air flotation pool is to discharge lentamente slowly along water (flow) direction, therefore the come-up mud of air flotation pool disturbs without any waterpower, has improved the condition of water quality treatment, has improved the effect of water quality treatment.
(embodiment) is further described the utility model below in conjunction with accompanying drawing.
Fig. 1 is the automatic air supporting mud discharging device of a circular air flotation pool structural representation.
Fig. 2 is the siphonic system synoptic diagram that is installed on the circular air flotation pool.
Fig. 3 is the automatic air supporting mud discharging device of a rectangle air flotation pool structural representation.
Fig. 4 is the siphonic system synoptic diagram that is installed on the rectangle air flotation pool.
Number in the figure is expressed as respectively: 1, and swash plate; 2, the siphon box; 3, the siphon pipe connecting; 4, siphon destructing tube; 5, the water inlet pipe valve; 6, the rising pipe valve; 7, sludge sump; 8, reactive tank; 9, siphon pipe connecting joint; 10, magnet; 11, water-supplying chamber; 12, the siphon pipe flowing water Valve; 13, siphon connects flexible pipe; 14, the water outlet thrust-augmenting nozzle; 15, air flotation pool; 16, reliever.
Siphon box ［ 2 ］ is the rectangular box of hollow, and siphon destructing tube ［ 4 ］ is arranged on siphon box middle lower portion, and the bottom, both sides of box is a siphon pipe connecting joint ［ 9 ］, and the length of siphon destructing tube can be used to regulate the length of sludge discharging period.Siphon box ［ 2 ］ is attracted on the magnet ［ 10 ］ that is installed on air supporting pool wall top, and can move up and down along magnet, is used for regulating the concentration of discharging mud scum.The feed-water end of the siphon pipe connecting ［ 3 ］ of circular air flotation pool is connected with the water-supplying chamber ［ 11 ］ of air flotation pool, the feed-water end and the water output duct ［ 4 ］ of the siphon pipe connecting ［ 3 ］ of rectangle air flotation pool join, for siphon box ［ 2 ］ is moved up and down freely, can adopt flexible pipe ［ 13 ］ with the junction of siphon pipe connecting joint ［ 9 ］.Swash plate ［ 1 ］ is located at the top of air flotation pool, and the swash plate of circular air flotation pool ［ 1 ］ should be installed in the central position of reactive tank ［ 8 ］, and the swash plate of rectangle air flotation pool ［ 1 ］ should be installed in the origin or beginning of reactive tank ［ 8 ］.The flow of air flotation pool is by the control of water inlet pipe valve ［ 5 ］ and rising pipe valve ［ 6 ］, valve ［ 5 ］ pass through the flow of flow greater than valve ［ 6 ］.
Automatically the principle of work of air supporting mud discharging device is such: pending water flows into air flotation pool by valve ［ 5 ］, flow out by valve ［ 6 ］, because the flow of valve ［ 5 ］ is greater than the flow of valve ［ 6 ］, the water level of air flotation pool rises, when the water level of air flotation pool surpasses the upper limb of siphon box ［ 2 ］, water flows out by the siphon pipe connecting simultaneously, siphon promptly begins, this moment, the aquifer yield of air flotation pool increased, the water surface begins to descend, when dropping to the following transverse plane of siphon destructing tube ［ 4 ］, siphon stops, and the water surface of air flotation pool begins again to rise.When the air flotation pool water surface rose, owing to be subjected to the component effect of swash plate ［ 1 ］, the mud of air flotation pool come-up just moved to sludge sump ［ 7 ］ direction slowly along water (flow) direction, enters sludge sump ［ 7 ］ at last.When the air flotation pool water surface rose to siphon box upper limb, siphon began again, again and again the mud of air flotation pool was entered sludge sump automatically like this.
Siphonal caliber can calculate like this.Suppose that handling the water yield is Q, the siphon flow is q, and the siphon time is T, and then the dominant discharge of valve ［ 5 ］ should be Q, and the dominant discharge of valve ［ 6 ］ should be Q-q/2.Siphon flow q can determine with following formula:
Circular air flotation pool q=(π D
2/ 4) * H/T;
Rectangle air flotation pool q=L * B * H/T;
In the formula: D is the diameter of circular air flotation pool;
B is the width of rectangle air flotation pool;
L is the length of rectangle air flotation pool;
H is the total height of siphon destructing tube, promptly comprises siphon box height and siphon destructive length of tube;
T is the siphon time.
Actual when selecting the siphon caliber for use comparable calculating big, because of the also available valve of siphon flow ［ 12 ］ is regulated.
The siphon time determines that according to the water quality of processed water the siphon time can be adjusted with the length and the siphon pipe flowing water Valve ［ 12 ］ of siphon destructing tube ［ 4 ］.Cross when low when the sludge concentration of air flotation pool come-up, siphon box ［ 2 ］ can be moved down, excessive when the sludge concentration of air flotation pool come-up, when influence mud extraction, can will move on the siphon box ［ 2 ］, but the highest the highest retaining that is no more than air flotation pool of the upper limb of siphon box is highly.
