Specific embodiment
As shown in Figures 1 to 4, breeding wastewater of the present invention waste separation equipment rotary drum Microfilter, including rack 1,
Sieve unit 2, gear unit 3, cleaning unit 4, squeezing unit 5 and filtrate collector unit 6.
The shell 12 that the rack 1 is mounted on 11 top of bracket including being placed in the bracket 11 on ground;12 side of shell is also set There is sealing plate 13.
2 Matching installation of sieve unit is on 12 top of shell of rack 1 comprising feed pipe 21, rotary drum sieve 22, diversion pipe 23 sieve the discharge nozzle of 22 side walls with rotary drum is mounted on.The feed pipe 21 is mounted in the middle part of 12 1 side of shell of rack 1, one end It stretches out 12 outside of shell to be connected to external waste pipe, the other end, which passes through, protrudes into 22 inside of rotary drum sieve in the middle part of 12 1 side of shell. Using 780 stainless steel sleeve shaft screen of φ, matching is located at 12 inside of shell of rack 1 and by internal layer fie screen and outside rotary drum sieve 22 The mesh structure that layer coarse strainer assembles.The rotary drum sieves and is fixedly installed with sleeve 221 in the middle part of 22 one end, fixed in the middle part of the other end It is connected with central axis 222;22 inside of rotary drum sieve is protruded into 221 one end of sleeve, and the other end successively stretches out rotary drum sieve 22 and shell 12 Outside is simultaneously hinged by bearing block and 11 one end top of bracket;21 other end of feed pipe of the sieve unit 2 is across the sleeve 221 protrude into inside rotary drum sieve 22;The central axis 222 is hinged by bearing block and 11 other end top of bracket.In rotary drum sieve 22 Wall is provided with diversion pipe 23 along flow path matching, which is spiral-shaped structure.22 inside of rotary drum sieve uses fine filtering Net improves filtering accuracy along flow path setting diversion pipe 23, since diversion pipe 23 makes stop of the waste water in rotary drum sieve 22 Time is elongated, and filter efficiency improves, and treating capacity is promoted;22 outside of rotary drum sieve uses coarse strainer, high pressure water can be prevented to fine filtering It is influenced caused by net, while prevention large granular impurity flows into external reservoir when fie screen occurs abnormal.
The gear unit 3 includes speed reducer 31, sprocket for main drive 32, auxiliary driving sprocket wheel 33 and chain 34;The speed reducer 31 For Matching installation on the downside of 11 one end of bracket of the rack 1, power output end is equipped with sprocket for main drive 32;The auxiliary driving sprocket wheel 33 rotary drums for being mounted on sieve unit 2 sieve 221 other end of sleeve of 22 one end, the auxiliary driving sprocket wheel 33 and sprocket for main drive 32 it Between by chain 34 matching connection.The speed reducer 31 drives the rotary drum sieve 22 of sieve unit 2 by chain 34, reduces equipment and rubs It wipes, for ease of maintenaince, and different speed reducers 31 can be taken according to site specific;The speed reducer 31 can be dropped using mute motor The noise generated in low machinery rotation process, improves operating environment;The speed reducer 31 uses variable-frequency motor, can be according to change of water quality Running speed is adjusted so as to energy conservation, so that it is applicable in water quantity and quality wider;To guarantee to operate the run stability of concentricity and equipment, Microfilter raw water water inlet end uses roller bearing, and sludge separates outlet end and uses the mute bearing of aligning.
The cleaning unit 4 includes spray tube 41 and autocontrol valve.The spray tube 41 is located at the rotary drum sieve of sieve unit 2 On the outside of 22 and Matching installation is outside the shell 12 of rack 1, and Matching installation has autocontrol valve on water inlet end pipeline, water outlet End protrudes into 12 inside of shell and sieves 22 outer wall against rotary drum.The autocontrol valve is located at 12 outer lower side of shell of rack 1 And use normally closed solenoid valve;Coil is attracted when the autocontrol valve is powered, and tap water sprays, and timing can be arranged on host computer Control cleaning, it is possible to use manual control is cleaned automatically.The spray tube 41 that the cleaning unit 4 uses, high pressure water is through spray tube 41 Nozzle fan-shaped high speed injection, dredge sieve, remove the solid that rotary drum sieves the attachment of 22 inner walls, flushing pressure >=0.3MPa, Periodic operation (automatic control setting or manually) is backwashed, rinse water consumption is reduced and operation hydraulic pressure is lower;The automatic control of installation Valve processed provides automatic, manual two kinds of cleaning ways, improves the degree of automation, can be carried out according to operating condition to rotary drum sieve 22 Thoroughly cleaning improves filter effect.
5 Matching installation of squeezing unit is in 12 downside of bracket of rack 1 comprising squeezer 51;The squeezer 51 matching It is mounted on 12 downside of bracket, the upper end is equipped with pressed liquor water inlet 511, and lower end is equipped with pressed liquor water outlet 512;The pressed liquor goes out The mouth of a river 512 is connected with pressed liquor effluent trough 513 and is connected to external reservoir by pressed liquor effluent trough 513;After squeezing Solid discharge is connected to bunker for collecting by manually or mechanically transporting.
On the bracket 12 of rack 1 for being located at 2 downside of sieve unit, entirety is in 6 Matching installation of filtrate collector unit Funnel-form, upper end are filtrate import 61, and lower end is filtrate (liquid 62;Wherein, the filtrate (liquid 62 of the filtrate collector unit 6 with should The pressed liquor effluent trough 513 of squeezing unit 5 connects.The filtrate collector unit 6 takes funnel like design, and comparison conventional cylindrical is set Meter, filtrate flow velocity faster, can effectively avoid because fine suspension is remaining in 6 inner wall of filtrate collector unit caused by being used for a long time Problem reduces the cleaning frequency, less workload.
Breeding wastewater of the present invention is as follows with the workflow of waste separation equipment rotary drum Microfilter:
External transmission device starting, sewage is introduced Microfilter by slush pump, after sewage enters Microfilter, sewage and wherein partial size is small Filtrate collector unit 6 is flowed into through fine screen mesh, the wide-meshed screen of rotary drum sieve 22 in the particulate matter of mesh size, partial size is greater than sieve screen apertures The impurity of diameter is rotated with Microfilter, mobile to the pressed liquor water inlet 511 of squeezing unit 5 with diversion pipe 23, is turned when remaining on When the solid residue of drum 22 screen surfaces of sieve enters squeezing unit 5 by pressed liquor water inlet 511, pressure slag unit 5 starts, pressed liquor Next unit lattice are flowed into filtrate, and solid residue is fallen into bunker for collecting by squeezer pressed liquor water outlet 512 by artificial (or machine Tool) transport;When the solid residue siltation of the screen surface of rotary drum sieve 22 is excessive influences operation, need to sieve rotary drum 22 sieves into Row cleaning can enable automatic or manual mode at this time and open autocontrol valve, and high pressure water ecto-entad sieves 22 sieves to rotary drum It is cleaned, while rotary drum sieves 22 sieves and operates normally, and internal impurity is discharged.
Structure of the invention design is simple, reasonable, and separative efficiency is high, effect is good, and filtering and recovery efficiency are high, operates with letter Single and easy to clean, applicable water quantity and quality is wide, and backwash water consumption is small.
