Detailed description of the invention
In order to further illustrate technical scheme, the detailed description of the invention of the present invention is described in conjunction with accompanying drawing, such as Fig. 3, this example is selected the ball float of commercially available stainless steel as ball float 211, polystyrene foam or other lightweight object can also be selected as ball float 211, select thin-wall stainless steel as device for fetching water 212, select the stainless (steel) wire in 1 millimeter of aperture to be covered at device for fetching water 212 as defecator 213, together with being welded with ball float 211 by device for fetching water 212, form floating water fetching device 21.
Such as Fig. 2, outlet one end of device for fetching water 212 is connected with floating attachment means 22, this example is selected commercially available corrugation plastic water pipe as floating attachment means 22；Select the concentration signal conversion equipment that the industry is general as communication device 24；Select the commercially available densitometer that the industry is general as concentration harvester 24, it is ensured that the lower end of concentration harvester 24 is less than the lower end of device for fetching water 212, and is connected with communication device 23；Select commercially available rubber hose as connecting tube 25；Select commercially available sphere pipe jointing as connection transfer device 26；Select commercially available pvc pipe as transition water pipe 27 and outlet pipe 28, will connect in order with upper-part, form supernatant extraction element 2.
As Fig. 4 select commercially available PLC that the industry is general as controlling the signal input unit 292 of device 29, control unit 293, memory element 294, signal output unit 295, select commercially available electric appliance control box as control chamber 291；Select commercially available electromagnetic control cut-off valve as electromagnetic valve 296, electromagnetic valve 296 is arranged on the middle part of outlet pipe 28, outlet pipe 28 is isolated into two parts, the general electronic corporation elements such as corresponding relay it is installed in control chamber 291 and is connected with electromagnetic valve 296, just completing the enforcement controlling device 29.
Such as Fig. 1, selecting the circular sludge-tank of the xoncrete structure that the industry is general as cell body 1, be arranged on the pool wall of cell body 1 by supernatant extraction element 2, wherein floating water fetching device 21 is placed on the water surface, just completes the enforcement of the present invention.
During application, when the supernatant in cell body 1 is less than when setting concentration, concentration harvester 24 sends signal, transmits a signal to control device 29 through communication device 23, controls device 29 and sends instruction, electromagnetic valve 296 is opened, position due to floating water fetching device 21 is higher than the lower part outlet of outlet pipe 28, and according to siphon principle, supernatant flows out automatically in outlet pipe 28, enter clear water reclaiming system, decrease the waste of water；Along with the decline of the water surface, when whose concentration concentration harvester 24 gathers more than setting value, concentration harvester 24 sends signal, sends control device 29 to, controls device 29 and closes electromagnetic valve 296, and current are cut off；Along with the precipitation of the mud in cell body 1, when concentration is less than setting value, circulate above procedure, it becomes possible to the supernatant in cell body 1 is reclaimed huge profit and uses；Meanwhile, when mud in sludge pump extraction cell body 1, owing to water content reduces, the extraction efficiency of sludge pump is just improved, and decreases many removal process, save the energy, improve production efficiency in follow-up mud anhydrates operation；Owing to have employed floating water fetching device 21 so that intake is constantly in water surface top, recovery is all the supernatant that concentration is little, namely clear water；Owing to have employed concentration harvester 24, can control to extract the concentration value of supernatant at any time, the water that will not make muddiness returns in clear water reclaiming system, flexibly connect owing to have employed, connection transfer device 26 with multi-angle, it is possible to adapt to SEA LEVEL VARIATION and the floating water fetching device 21 that causes and the change in location of concentration harvester 24, owing to have employed siphon principle, need not additionally increase power set and just can complete the extraction of supernatant, save the energy.
