Wherein:
Drive unit 1, casing 2, case 3, rotary drum 4, flusher 5, microfiltration net 6, level detection 7, movable observing door 8, dirt discharge groove 9, rotary drum bracing or strutting arrangement 10, flush water pump 11, pipe-line system 12.
Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of rotary drum micro-filter that the present invention relates to, it is formed primarily of drive unit 1, casing 2, case 3, rotary drum 4, flusher 5, microfiltration net 6, level detection 7, movable observing door 8, dirt discharge groove 9, rotary drum bracing or strutting arrangement 10, flush water pump 11 and pipe-line system 12.
Drive unit 1: provide power for rotary drum rotates, adopt direct-connected driving, does not have intermediate transmission secondary, and structure is simple, stable.
Casing 2: casing is a semi-closed structure is rotary drum carrier.Inside is provided with inhalant region and current stabilization district, the flow shape entered in rotary drum is stablized, improves filter effect.
Case 3: make complete machine be in enclosed construction, effectively avoid water to spatter, improve operating environment.
Rotary drum 4: be microfiltration net carrier, one end is closed, other end Open architecture, and filtrate is entered by open end, discharges after filtration after net filtration.Blind end is connected with drive unit.
Flusher 5: for the cleaning of microfiltration net and regeneration provide safeguard.This equipment provides 2 cleaning water routes, tunnel, can open two-way cleaning thus ensure filter gauze cleaning effect when filtrate concentration of suspension is higher.Described flusher 5 comprises flush water pump 11, pipeline and shower nozzle.
Microfiltration net 6: these parts are the core component of this equipment.Not only meticulous 316L stainless (steel) wire in these parts adopts special processing process to be connected on upper and lower 316L stainless steel semicircular steel wire intersection rack, and is compressed in stainless steel sheet frame, makes screen pack ensure enough filter areas but also ensure enough intensity.Compare other fixed form, this kind of semicircular steel wire net rack is more smooth, retains and pulls the probability hanging thread suspension in sewage lower, fully ensure that the treatment effect of sewage.The trim designs of screen pack and rotary drum body is ingenious, can dismantle very easily and install.
Level detection 7: this equipment is with liquid level detection device, and detectable basic, normal, high three water levels, combine with frequency converter and automatically realize the basic, normal, high three kinds of speed of drive unit and run, can ensure that filter effect can make again life of equipment extend.And there is ultra low water level shutdown and surcharge water level warning function.
Movable observing door 8: movable observation door facilitates daily tour, safeguards and maintenance, and switch is flexible.
Dirt discharge groove 9: the feeder that rotary drum carries can be collected in dirt discharge groove by filtering the suspension intercepted, to stick on filter screen and the sewage of fine suspension after flusher rinses in mesh to be also collected in dirt discharge groove and to discharge through blow-off line simultaneously, fouling product is not assembled at device interior.
Rotary drum bracing or strutting arrangement 10: play the effect supporting rotary drum and normally run.Adopt special non-maintaining material to make, without the need to oily and regular maintenance, long service life and dismounting and change are convenient.
Flush water pump 11: for flusher provides high pressure, clean water source, the water after self filtering is taken from cleaning water source.For making nozzle not block, pipeline separately establishing one filter, ensure that the cleaning performance of flusher to screen pack more fully.Needed for this equipment, washing water quantity is very little, only accounts for about 0.5% of its own processing capabilities, makes the more energy-conserving and environment-protective of this equipment.
Pipe-line system 12: water-in and water-out and the emptying use of equipment self.
During work, sewage flows in hollow rotary drum, and due to the effect of gravity, have filter screen Inside To Outside to flow out, the suspension in water is trapped within inside stainless steel filtering net.Rotary drum slowly rotates, and after flush water pump extracts filter, water outlet carries out backwash to filter screen.Flushing water is rinsed filter screen by inside filter screen lateral by the shower nozzle being positioned at rotary drum top, and the particulate matter rinsed is collected by dirt discharge groove, and by sewage pipe device for transferring.
To sum up this device structure is simply small and exquisite, floor space is little, treatment effect good, easy to maintenance, processed in units expense is low, compares the more energy-conserving and environment-protective of other filter plants.
