Description

Self-flow pattern rotary drum microfroc filter

Technical field

The utility model relates to a kind of self-flow pattern rotary drum microfroc filter.Be used for municipal wastewater and separate superfine fibre thing and suspension with trade effluent; Be used for the filtration of sewage Pai Hu, Pai Jiang, row maritime works's journey suspended particulate substance; Be used for recovery such as industrial residue, useless slurry, fiber; The preparation that also can be used for industry and conditioned water is filtered.

Background technology

The superfine suspension in the waste liquid is filtered in the existing market at present, and filtering accuracy requires than higher main employing quartz sand filtration and adopts mechanical pressures such as micron order wire netting, filter cloth to filter.Adopt the quartz sand filtration floor space very big, invest also hugelyr, the filtration energy consumption is than higher, and the line service amount is very big.When adopting mechanical pressures such as micron order metal screen, filter cloth to filter, existing technology adopts the pressure type filter type, when adopting nonmetal filter cloth etc. to filter, its shortcoming is that loss in head is bigger in the filter process, not enough and the obstruction easily of the mechanical strength of filter cloth, therefore must often change filter cloth, the filtration energy consumption is bigger, and the line service amount is also bigger; When adopting metal mesh filter, its shortcoming is that loss in head is bigger in the filter process, so equipment adopts the closed press filtration that has, and adopts discontinuous backwash usually, and mesh stops up easily, filters energy consumption than higher, and the operation of equipment is more complicated also.

Summary of the invention

The purpose of this utility model provides the self-flow pattern rotary drum microfroc filter that a kind of energy consumption is little, intensity is high, filtering accuracy is high, opening of sieve can not stop up.

The technical scheme that realizes above-mentioned purpose is: a kind of self-flow pattern rotary drum microfroc filter, comprise water inlet pipe, outlet pipe, motor, filter residue feeder, blow-off pipe, cabinet and can be rotated to support on the interior rotary drum of cabinet, rotary drum is provided with filter screen, the filter residue feeder is positioned at rotary drum, blow-off pipe is communicated with the filter residue feeder, motor is connected with rotary drum by transmission mechanism, and the cabinet top also is equipped with the cover plate that can cover rotary drum, and the installed inside of cover plate has the high pressure washing pipe.

After adopting technique scheme, owing to the cover plate that can cover rotary drum also is installed at the cabinet top, and the high pressure washing pipe is arranged in the installed inside of cover plate, ceaselessly spray water by the high pressure washing pipe to filter screen, can prevent that promptly opening of sieve from stopping up, make ceaselessly continuous filtration work of rotary drum, reduced the time of safeguarding, improved operating efficiency.The utility model is by gravity filtration, the no pressure loss, and energy consumption is little.

The utility model also has floor space little, and it is big to filter the water yield, invests lessly relatively, installs, moves simple advantage.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～5, a kind of self-flow pattern rotary drum microfroc filter, comprise water inlet pipe 3, outlet pipe 10, motor 5, filter residue feeder 11, blow-off pipe 8, cabinet 1 and can be rotated to support on rotary drum 12 in the cabinet 1 by roller 14, the bottom of cabinet 1 has under-chassis 15, motor 5 is installed on the cabinet 1 by its support 7, rotary drum 12 is provided with stainless steel filtering net 13, stainless steel filtering net 13 is pressed and is embedded on the rotary drum 12, filter residue feeder 11 is positioned at rotary drum 12, blow-off pipe 8 is communicated with filter residue feeder 11, motor 5 is connected with rotary drum 12 by gear drive, gear drive is made up of gear reduction unit and the gear that is installed on the rotary drum, the gear that gear reduction unit drives on the rotary drum 12 rotates, and cabinet 1 top also is equipped with the cover plate 2 that can cover rotary drum 12, and the inside top of cover plate 2 is equipped with high pressure washing pipe 4.

Filter screen 13 can also adopt the metal screen of other material except that adopting stainless steel filtering net.

As shown in Figure 1, the top of outlet pipe 10 is equipped with overflow pipe 9, and overflow pipe 9 communicates with cabinet 1 inner chamber.When water level is too high in the cabinet 1, can also discharge from overflow pipe 9 in the cabinet 1.

As shown in Figure 1, scavenge pipe 6 is installed also on the cabinet 1, this scavenge pipe 6 communicates with filter residue feeder 11.By being set, can regularly clean by scavenge pipe 6 every 10 days or first quarter moon to filter residue feeder 11.

Operation principle of the present utility model is as follows: sewage enters rotary drum by free drop; The SS thing is the screen pack inboard of 20～100 microns specifications attached to the aperture, and clear water relies on gravity by stainless steel filtering net 13; Rotary drum 12 at the uniform velocity rotates with 3～4rpm under the drive of motor 5; 4 pairs of filter screens of top high-voltage flusher mesohigh cleaning hose 13 carry out cleaning automatically continuously; By high pressure washing, rotary drum 12 inboard screen surface obtain cleaning; Filter residue is fallen in the interior waste residue feeder 11 of rotary drum, and slag liquid enters the filter residue treatment system by blow-off pipe 8.
