The specific embodiment
Below in conjunction with Figure of description and the specific embodiment the utility model is described in further detail.
Filter cloth rotating disk filter plant provided by the utility model is mainly used in the advanced treating of sewage, Fig. 1 shows the structural representation of a kind of filter cloth rotating disk of the utility model filter plant, and this filter plant mainly comprises filter disc assembly 10, water outlet six square shaft assemblies 20, backwash and sludge drainage system 30, drive unit 40 and tensioning apparatus 50 as can be seen from Figure.Filter plant of the present utility model is installed in the specially designed concrete filter tank, and its effect is to remove the various impurity that exist with suspended state in the sewage, improves sewage disposal plant effluent water quality, makes processing water SS up to standard.
Backwash and sludge drainage system 30 comprise dredge pump 31, dredge pump 31 is connected with backwash tube 33 with discharge pipeline 32 respectively, as shown in Figure 5, discharge pipeline 32 is provided with spoil disposal motor-driven valve 36, backwash tube 33 is provided with backwash motor-driven valve 35, the afterbody of backwash tube 33 is connected with sucker 34, the suction inlet of sucker 34 is attached to filter cloth 12 surfaces, sucker 34 is arranged on the flushing machine support 37 by torsionspring 39, one end of flushing machine support 37 is fixed on the wall of filter tank, the other end is fixed on (height of this filter tank wall is higher than the height of an above-mentioned end filter tank wall) on the wall of filter tank by adjustable drawbar 38, flushing machine support 36, adjustable drawbar 35 and filter tank wall structure triangular in shape, as shown in Figure 6; Drive unit 40 comprises reductor, and reductor is connected by the gear wheel 24 of chain with six side's central shaft assemblies 20.
By among Fig. 1 as can be seen, filter cloth rotating disk filter plant of the present utility model also comprises the tensioning apparatus 50 that is connected with chain, tensioning apparatus 50 is by installing tightener sprocket additional in the non-stress side, by adjusting the purpose that its position reaches tension chain, if chain is loose excessively, can reduce chain service life, the stable drive degree also can reduce, and jumps tooth easily.
The utility model is arranged in the filter tank; also be provided with liquid level gauge 60 and high-order float switch in the filter tank; be used for monitoring the water level in the filter tank, judge by the level value that liquid level gauge is measured whether system starts backwash and spoil disposal program, high-order float switch is the high liquid level protection to the filter tank.Described electric control system is connected with liquid level gauge with backwash and sludge drainage system 30, drive unit 40 respectively, is used for this filter plant is carried out automation control.Electric control system in the present embodiment adopts current state-of-the-art PLC automatic control system, adopt Siemens's touch screen technology simultaneously, real time record equipment operation information, show running status and the alarm condition of entire equipment, can arrange and check the setting of systematic parameter arbitrarily by touch-screen.In filter process, along with gathering of mud on the filter cloth, the filter cloth filtration resistance increases, the filter tank water level raises gradually, change by liquid level in the liquid level gauge detection cell, also clean setting value (high water level) for reaching in the filter tank, electric control system starts backwash and sludge drainage system 30, the mud on the filter cloth is aspirated the beginning backwash process by dredge pump.This equipment adopts the design of very hommization, realizes the manual, automatic of system and three kinds of control of Long-distance Control function, realizes the system's operation under the various situations.
The running status of this filter plant comprises: filtration, backwash and spoil disposal state.Filter medium is filter cloth 12, and filter cloth 12 is attached on filter disc 11 cards, and gusset plate 13 plays reinforcement and is connected the filter disc effect, and filter cloth adopts novel nano-material, has the feature of hydrophobic oleophobic, and impurity is difficult for sticking, and backwash is cleaner.The sewage gravity current enters the filter tank, and filter disc 11 is immersed in the sewage fully, filters by filter cloth 12, and filtered fluid is collected by hollow six side's central shafts 21, and gravity current is discharged the filter tank by effluent weir, and whole process is continuous.Bearing spider 24, bearing block 22 and roller 823 work six side's central shaft effects of support, and in filter process, the part sludge absorption forms sludge blanket gradually in filter cloth 12 outsides.Along with gathering of mud on the filter cloth 12, filter cloth 12 filtration resistances increase, and the filter tank water level raises gradually.Electric control system changes by liquid level in the liquid level gauge monitoring pool, when liquid level in this pond arrives cleaning setting value (high water level), drive unit 40 starts, motor sprocket drives by chain and goes up gear wheel 7 rotations on the motor reducer, gear wheel 7 is connected on six side's central shafts 21 by bolt, so that six side's central shafts 21 and filter disc 11 rotate together in company with gear wheel.When liquid level in the filter tank arrives cleaning setting value (high water level), PLC can start backwashing pump (dredge pump), the beginning cleaning process, backwashing pump starts, electrical ball valve (backwash motor-driven valve 35 and spoil disposal motor-driven valve 36) is opened, and it is external that the sucker 34 back suction suctions of the mud on filter cloth surface by backwash and sludge drainage system 30 go out the filter tank.During cleaning, but filter tank continuous filtration.During the filtration, filter rotating disk and be in static state, be conducive to the pond bottom sediments of mud.During the cleaning, filter rotating disk and rotate with 0.4 rev/min speed.The mud granule that gathers on the filter cloth is absorbed by sucker 34 in backwashing pump negative pressure suction filter cloth surface, and the water that filters in the rotating disk is outwards aspirated simultaneously from the lining, and filter cloth is played cleaning action.Instantaneous flushing area only accounts for about 1% of full filtration rotating disk area.Backwash process is intermittently.
During normal the flushing, 2 filtration rotating disks are one group, and by electrical ball valve 2 controls on the automatic switchover suction pump pipeline, cleaning of each group hockets in complete cleaning process of filter cloth rotating disk filtering ponds, and the work of dredge pump therebetween is continuous.When influent quality worsens suddenly, during backwashing period≤15 minute, system will start emergency measure, start 2 dredge pumps simultaneously, filter rotating disks (4 rotating disks) to 2 groups and carry out backwash, recover normal until backwashing period.
The filtration rotating disk of fibre turntable filter has at the bottom of the bucket shape pond, is conducive to the collection of pool bottom sludge.The sludge-tank bottom sediments has reduced the sludge quantity on the filter cloth, can prolong filtration time, reduces the backwash water yield.Through a time period of setting, system starts sludge pump, by pond bottom hole discharge pipeline mud is back to plant area's drainage system.Can arrange spoil disposal time and cycle by touch-screen.
