Embodiment
For features described above of the invention and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing, make detailed Carefully it is described as follows, but the present invention is not limited thereto.
Referring to figs. 1 to Fig. 6
A kind of sewage-treatment plant, including a filtering ponds 10, the side outer wall top of the filtering ponds are provided with intake chamber 20, the water inlet groove sidewall is provided with the water inlet 21 for penetrating filtering ponds, and filtering ponds opposite side outer wall is provided with effluent trough 30, institute State to be provided with filtering ponds makes spot inhale horizontal drum shape mistake attached to it by drive mechanism driving rotation for filter sewage Device 40 is filtered, the water purification output end of the cylinder shape filter is connected with effluent trough, and the water purification obtained after filtering is defeated Go out.The scraping dirt mechanism 50 for will inhale spot attached to it and strike off and exclude is additionally provided with the cylinder shape filter, So that cylinder shape filter reuses.It is additionally provided with the filtering ponds for taking out the sludge discharge of filtering ponds bottom Mechanism is inhaled, so as to prevent sludge to be deposited in filtering ponds bottom, reduction manually removes sludge cost, ensures the continuous work of the sewage-treatment plant Make.
Above-mentioned effluent trough is by being arranged at filtering ponds opposite side and input is arranged at the first cell body of filtering ponds middle part of sliding channel 31 form with the overflow groove 32 for being connected to the first cell body sidepiece, and the overflow groove water inlet end 33 is less than water inlet, so that mistake Water in filter tank continues to flow outward, forms siphon principle.
Above-mentioned cylinder shape filter includes the fixed mount 41 being arranged in filtering ponds, and one end is provided with the fixed mount With the central tube 42 of the rotation connection of the first cell body input and other end closing, the section of the central tube is hexagonal, center The other end of pipe is connected through bearing block with fixed mount, if central tube is provided with dry plate screen pack 43 along its axially spaced-apart, from And filter area is improved, strengthen filter efficiency.If the screen pack includes the filtering screen frame that dry plate is connected to central tube periphery 44, the both sides of the filtering screen frame make spot inhale filtering flannelette 45 attached to it, institute covered with one layer of filter sewage respectively State central tube with filter screen frame joint portion it is circumferentially spaced be provided with the water purification entrance 46 for penetrating central tube, so as to sewage pass through Filter flannelette filters laggard water purification entrance and enters central tube.
Above-mentioned filtering flannelette is fine animal fibre or superfine fibre, so as to which spot is fully filtered.
Above-mentioned scraping dirt mechanism includes being arranged on the scraper plate 51 that screen pack both sides are tightly attached on filtering flannelette, and this two is scraped Plate shifts to install up and down, and dislocation distance is 20 ~ 100mm, preferably to strike off spot.It is square along its length on the scraper plate To pick trough 52 is provided with, so as to which the spot scraped is siphoned away by pick trough.The pick trough and the soil pick-up being connected on scraper plate Pipe 53 is connected, and suction pump 54 of the dirt sucking tube through being fixed on fixed mount is connected with soil pick-up house steward 55, and the soil pick-up is total Manage and be connected with being arranged at filtering ponds top and stretching out the blow-off pipe 56 of filtering ponds, valve body 57 is provided with the blow-off pipe.
As shown in fig. 6, the position on above-mentioned scraper plate scraper plate on the upside of pick trough is in up-small and down-big trapezoidal shape, and the portion The inclined-plane of position is engaged with flannelette, and the position being located on the scraper plate on the downside of pick trough is in up big and down small trapezoidal shape, and the portion The inclined-plane of position is engaged with flannelette, to extrude flannelette in flannelette rotation process and to peel off sludge on flannelette, so as to reach The effect of scraping dirt.The capping 511 being connected with dirt sucking tube is connected with the outside of the scraper plate.The inclined angle 512 in inclined-plane For 10 ~ 20 °.
Spacing between position on above-mentioned scraper plate on the upside of the pick trough and the position on the downside of pick trough for 5 ~ 30mm, and spacing is adjustable, to adjust the size of pick trough according to the dirty situation of flannelette.
Above-mentioned drive mechanism includes being arranged at the toothed disc 71 of central tube one end, and the toothed disc is through driving-chain 72 by setting The motor 73 being placed on the upside of filtering ponds drives, and so as to drive cylinder shape filter device to rotate, realizes that scraper plate repeats to scrape screen pack Surface, so as to which the spot adhered to it is scraped and siphoned away spot by pick trough.
Above-mentioned aspirating mechanism includes the sludge suction pipe 61 for stretching into filtering ponds bottom, and the sludge suction pipe is configured in filtering ponds The sludge pump 62 on top is connected with stretching out the blow-off pipe 57 of filtering ponds, so as to which sludge is discharged outside filtering ponds.
The application method of the sewage-treatment plant:
Sewage is sent into filtering ponds by intake chamber, because overflow groove water inlet end is less than water inlet on effluent trough, in current The process of constant flow produces siphon principle, and sewage then continually filters from screen pack, and is exported by effluent trough;Start Drive mechanism rotates cylinder shape filter, while opens suction pump, and cylinder shape filter is when rotating, scraping dirt machine The spot that the scraper plate of structure will be adhered on filtering flannelette scrapes, and is entered by wash water trough, and discharges filtering ponds by blow-off pipe; After pond work a period of time to be filtered, sludge pump is opened, the sludge of filtering ponds bottom is discharged by sludge suction pipe and blow-off pipe Filtering ponds, and repeated with this so that sludge of the available continuous work of filtering ponds without shutting down cleaning deposition.
It is noted that in an embodiment of the present invention, above-mentioned work includes the first working time and for a period of time Two working times, or some time T combination;During first working time, the cylinder shape filter can be just Turn, during the second working time, the cylinder shape filter can be reversion;Then it is each if some time T In period T, alternately forward and backward, the spot that can effectively remove on filtering flannelette is rotated and reverse by this, and can also have Effect extends the service life of filtering flannelette.
