The mould bases schematic diagram of Fig. 2 disc filter of the present utility model.
Wherein, description of reference numerals is as follows:
1 base, 2 bracing frames
5 slots
The specific embodiment
The utility model can fully be understood by following embodiment explanation, make those of ordinary skill in the art to realize, yet enforcement of the present invention is not subjected to the restriction of following example.
As shown in Figure 2, and please also refer to Fig. 1, disc filter of the present utility model comprises filter and backwash device.Wherein this filter comprises: a center rotary drum, and this center rotary drum is cavity body structure, and water to be filtered is along in the center that axially the enters rotary drum of center rotary drum; With a plurality of disc type filters, the disc type filter is sheathed on the rotary drum of described center coaxially, and each disc type filter includes mould bases and the filter cloth that is fixed on the mould bases, and described mould bases and filter cloth constitute a plurality of filter chambers; Be provided with an opening corresponding to each filter chamber on the rotary drum of center, water to be filtered enters the filter chamber by this opening.This backwash device comprises: the backwash water pump; Backwash is responsible for, and it is connected with the backwash water pump, and is arranged on the top of described disc type filter; Backwash arm and backwash are responsible for and are connected, and the side that is arranged at described disc type filter is with parallel with described filter cloth; The backwash nozzle, it is arranged on the ejection end of described backwash arm, in order to wash filter cloth towards the direction opposite with the filtering direction of described filter cloth; The backwash water feeder, it is suspended at the upper area of described center rotary drum inner chamber, 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 rotary drum of center.
See also Fig. 2 again, described mould bases comprises base 1, bracing frame 2 and last packaging part 3, base 1 is arranged on the outer surface of center rotary drum, the lower end of bracing frame 2 is arranged on the base 1, bracing frame 2 upper ends are connected with last packaging part 3, and wherein bracing frame 2 is provided with the water discharging boss 4 towards the position of inside, filter chamber.It is circular-arc that the water discharging boss 4 can be, and also can be other shape.Form close gap between the water discharging boss 4 and the filter cloth.Bracing frame 2 is provided with slot 5, and filter cloth fixes on bracing frame 2 by inserting slot 5.Base 1 is circular-arc, matches with center rotary drum outer surface.
