Described buffering mixing channel 21 has thickened sludge import 211 and body refuse import (non-label), described body refuse import is towards the discharge end 132 of described scraper plate 13, and be positioned at the below of described discharge end 132, described body refuse import is provided with body refuse funnel 212.Described press filtration groove 22 has dry mud outlet 221 and pressing filtering liquid outlet 222.Mixer is provided with in described buffering mixing channel 21.Be provided with helical axis in described press filtration groove 22, described helical axis is connected with drive motors and is driven by described drive motors and rotates.
The operation principle of above-mentioned Novel sewage body refuse Combined Treatment machine is as follows: former water to enter in rotary drum Microfilter 10 water inlet 111 to enter to cushion chamber 15 through former water elevator pump, former water is through cushioning water distribution baffle plate water distribution uniformity on rotary sieve 12, under the effect of gravity and rotational shear, former water flows out rotary drum Microfilter 10 through rotary sieve 12 through delivery port 112, enter subsequent treatment facility, and the larger particle 30 of particle diameter retain by rotary sieve 12, these particles 30 to reside on rotary sieve 12 when scraper plate 13, scraped by scraper plate 13, and fall in body refuse funnel 212 along scraper plate 13, enter in buffering mixing channel 21, while the fine particle 30 retained at rotary drum Microfilter 10 enters buffering mixing channel 21, thickened sludge in outside sludge concentration tank enters into buffering mixing channel 21 through thickened sludge import 211, under the stirring action of mixer, particle 30 and thickened sludge mixing, and be fed through in press filtration groove 22, then, under the driving of drive motors, helical axis is driven constantly by before the sludge mixture screw of mixing, when helical axis rotates, be located at the multiple lamination relative movement of admittedly living of impeller-hub periphery, under gravity, water leaches from the lamination gap of relative movement, realizes rapid concentration.Move forward along with the rotation of helical axis keeps through concentrated mud; Along cake outlet direction, the pitch of helical axis diminishes gradually, and the gap between ring and ring also diminishes gradually, and the volume of helical cavity constantly shrinks; Under the effect of exit back pressure plate, interior pressure strengthens gradually, and under at auger axle, running promotes continuously successively, the moisture in mud is squeezed discharges, and filter cake solid content constantly raises, and realizes the continuous dehydration of body refuse, and the mud after dehydration exports 221 from dry mud and falls.
The inner side of described rotary sieve 12 arranges water spray system 18, when rotary sieve 12 is blocked, to cause in cushion chamber 15 former waterborne is raised to a high position for setting until arrive the position set by level switch, now, level switch drives water spray system 18 to start, and carries out backwash to rotary sieve 12.
The particle 30 (i.e. body refuse) intercepted and captured due to rotary drum Microfilter 10 part and thickened sludge mix, be conducive to sludge dewatering, add the flocculants such as PAM carry out mud-water separation so can not be used in buffering mixing channel 21, body refuse directly can enter folded spiral shell machine 20 part and dewater.
In sum, above-mentioned Novel sewage body refuse Combined Treatment facility have the following advantages:
1, particle 30 larger for former water central diameter grain is first tackled by the rotary sieve 12 of rotary drum Microfilter 10 by Novel sewage body refuse Combined Treatment machine, then by scraper plate 13, the particle 30 on rotary sieve 12 is scraped in buffering mixing channel 21, mix with thickened sludge, finally undertaken dewatering and extruding forming filter cake by press filtration groove 22 again, thus make compact conformation, floor space little, and can avoid using the flocculants such as PAM, contribute to reducing costs, be applicable to multiple different sewage disposal in addition.
2, because the housing 11 of rotary drum Microfilter 10 and folded spiral shell machine 20 all adopt stainless steel to make, thus play corrosion-resistant, easy for installation, be convenient to maintenance and change, weight is little, be convenient to carrying; Can fix by direct expansion bolt when this rotary drum Microfilter 10 and folded spiral shell machine 20 overall package, and without the need to doing groove.
3, because the grizzly bar of rotary sieve 12 is inverted trapezoidal cross section, particle 30 is made not easily to block filter screen.
4, rotary sieve 12 adopts made by polytetrafluoroethylmaterial material, thus makes this rotary sieve 12 more wear-resisting, corrosion-resistant, and is convenient to change.
5, because rotary sieve 12 adopts buncher to control, so rotary drum Microfilter 10 can make it to keep optimum Working according to flow of inlet water.
6, by arranging water spray system 18, the impurity being pasted onto rotary sieve 12 surface very on a small quantity can be brushed away, not easily blocking, realize the function with oneself's cleaning; And rotary sieve 12 is after rinsing in secondary, can reach best clear grid effect, be provided with the aperture plate 122 that two-layer laminate is arranged simultaneously, the particle 30 after being rinsed can be tackled by it, thus reaches best filter effect.
7, helical axis low-speed running, the rotating speed of helical axis about 2 ~ 3 revs/min, power pole is low, and fault is few, and noise vibration is little, handling safety.
8, control rotary drum Microfilter 10 and folded spiral shell machine 20 by electrical control cubicles, thus make simple to operate, can with bubble medicine machine, enter dredge pump, dosing pump etc. and carry out interlock, realize unmannedly continuously running for 24 hours, the regular maintenance time is short, and upkeep operation is simple.
9, in actual use, change parts and only have helical axis and travelling ring, thus make life cycle long.
The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
