The specific embodiment
In order further to understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet accompanying drawing only for reference with the explanation usefulness, be not to be used for the present invention is limited.
Embodiment 1: see also Fig. 2 and Fig. 3, wherein Fig. 2 is the schematic cross-section of disc filter of the present invention; Fig. 3 is another schematic cross-section of disc filter of the present invention, and it is opposite with direction shown in Figure 2.Disc filter of the present invention comprises filter and backwash device.Wherein this filter comprises: a center rotary drum 11, and this center rotary drum 11 is cavity body structure, and water to be filtered is along in the center that axially the enters rotary drum 11 of center rotary drum 11; With a plurality of disc type filters 12, described disc type filter is sheathed on the described center rotary drum 11 coaxially, and each disc type filter 12 includes mould bases 13 and the filter cloth 14 that is fixed on the mould bases 13, and described mould bases 13 constitutes a plurality of filter chambers with filter cloth 14; Be provided with an opening corresponding to each filter chamber on the center rotary drum 11, water to be filtered enters the filter chamber by this opening.This backwash device comprises: backwash water pump 15; Backwash is responsible for 16, and it is connected with backwash water pump 15, and is arranged on the top of described disc type filter 12; Two backwash arms 18,18 ', it all is "T"-shaped, be responsible for backwash to be connected, and the side that is arranged at described disc type filter 12 is with parallel with described filter cloth 14; Backwash water controller 17,17 ' is arranged on the backwash arm 18,18 ', in order to the control backwash water yield and hydraulic pressure; A plurality of backwash nozzles 19, it is arranged on described backwash arm 18,18 ' the ejection end, in order to wash filter cloth 14 towards the direction opposite with the filtering direction of described filter cloth 14, other sees also Fig. 2, be arranged on two between the disc type filter 12 backwash arm 18 and 18 ' ejection end both sides be equipped with backwash nozzle 19; Backwash water feeder 20, it is suspended at the upper area of described center rotary drum 11 inner chambers, and in order to collecting backwash water and to avoid polluting water to be filtered, and its position is higher than the water level of water to be filtered in the center rotary drum 11.
See also Fig. 2 again, backwash nozzle 19 on the backwash arm 18 ' that set backwash nozzle 19 is adjacent on described arbitrary backwash arm 18 is staggered to be arranged, promptly the arbitrary backwash nozzle ejection 19 on the backwash arm 18 the eject position on the filter cloth 14 all with backwash arm 18 ' on the eject position that is injected on the filter cloth of arbitrary backwash nozzle 19 inconsistent.
The course of work of the present invention is described below:
When disc filter carried out filter operation, center rotary drum 11 remained static, and water to be filtered enters from an end of center rotary drum 11, enters in the filter chamber by the opening on the rotary drum of center.Under the effect of differential water pressures inside and outside the filter chamber, water to be filtered filters out impurity by filter cloth 14.Clear water after the filtration flows out from filter cloth 14.
When disc filter carries out backwash operation, center rotary drum 11 is in rotary state, clear water suction backwash after backwash water pump 15 will filter is responsible in 16, pass through the ejection from backwash nozzle 19 of backwash arm 18 and 18 ' back again, filter cloth 14 is cleaned from the direction opposite with the filtering direction of filter cloth 14.The water that has impurity after the cleaning flows to from the filter chamber in the backwash water feeder 20 by the opening on the center rotary drum 11, thereby avoids polluting below water to be filtered.Wherein, the flow and the hydraulic pressure of water in backwash water controller 17 and 17 ' control backwash arm 18 and 18 '.Can realize 19 whiles of backwash nozzle on backwash arm 18 and 18 ' or replace water spray by backwash controller 17 and 17 '.
In the present embodiment, about 60 seconds of filter operation cycle, about 20 seconds of backwash operation cycle.
Disc filter provided by the present invention can be according to the needs of backwash, alternately or spray backwash water work simultaneously, reach the effect of flexible modulation.It can also make full use of the injection water of backwash nozzle, and each is even as far as possible on the backwash rate in the radial direction to make filter cloth, and reduces the rinse water consumption, reaches water saving, reduces the effect of filter cloth washing fatigue, and filter efficiency is improved greatly.
Embodiment 2: in the present embodiment, the primary structure of disc filter is substantially the same manner as Example 1, and its difference is that the backwash water controller can be controlled backwash arm pulsed water spray.Wherein, the backwash nozzle on each backwash arm can be synchronous or nonsynchronous pulse water spray.Adopt the pulsed water spray can obtain better effect, comparing with traditional injecting type water spray also has the effect of water saving.
Embodiment 3: in the present embodiment, the primary structure of disc filter is substantially the same manner as Example 1, and its difference is that the backwash arm sprays to filter cloth and mixes gas-liquid.Adopt to mix gas-liquid, can further save the wash water amount, and mix gas-liquid and be ejected into and produce foam on the filter cloth, filter cloth is also had better cleaning action.
Embodiment 4: in the present embodiment, the primary structure of disc filter is substantially the same manner as Example 1, and its difference is that mould bases and nozzle are provided with sensor (scheming not shown), in order to when backwash arm nozzle passes through mould bases, closed backwash nozzle is to prevent to spray mould bases.And through behind the mould bases, then open the backwash nozzle and continue the flushing filter cloth.To the damage of mould bases, prolong the service life of mould bases when adopting this design to avoid spraying.
Embodiment 5: in the present embodiment, the primary structure of disc filter is substantially the same manner as Example 1, and its difference is that the backwash nozzle is provided with angle regulator (scheming not shown), regulates spray angle.Wherein, each backwash nozzle promptly may be adjusted to unified spray angle, also can regulate angle separately as required independently.Adopt this design, the flushing water of backwash nozzle ejection can wash filter cloth at an angle, sprays too macrolesion filter cloth of dynamics in the time of both can avoiding directly washing, also can be from different angle flushing filter clothes to get better developing result.
Embodiment 6: in the present embodiment, the primary structure of disc filter is substantially the same manner as Example 1, and its difference is that backwash nozzle position on the backwash arm is unfixing, moves along backwash arm length direction.Wherein a kind of backwash arm that is designed to is provided with moving slider (scheming not shown), and the backwash nozzle is arranged on the moving slider, and the backwash nozzle can be certain frequency ground with moving slider and moves along backwash arm length direction under user control like this.Each is even as far as possible on the backwash rate in the radial direction to adopt this design can further make filter cloth, and reduces the rinse water consumption, reaches water saving, reduces the effect of filter cloth washing fatigue, and filter efficiency is improved greatly.
The present invention can be conceived arbitrarily and formed many modifications by those of skill in the art, yet does not all break away from the appended claim scope of the present invention.
