Description
Technical field
The present invention relates to filtering equipment field, more particularly to a kind of dewatering and filtering mud equipment of easy desliming.
Background technology
Sludge dewatering refers to the primary of fluidised form, concentration or digested sludge removing moisture, is converted into semisolid or solid-state clod
A kind of method for sludge treatment.After dehydration, moisture percentage in sewage sludge can reduce by 80 55 percent to percent, depending on sludge
Depending on the property of sediment and the efficiency of dehydration equipment.The further dehydration of sludge then claims sludge drying, dewatered sludge it is aqueous
Rate is less than 10.
Device for dehydrating sladge waste relatively common at present mainly has following a few classes：
First, plate and frame sludge dewatering equipment：Under air-tight state, the sludge squeezed into through high-pressure pump passes through the extruding of sheet frame, makes sludge
Interior water is discharged by filter cloth, reaches dehydration purpose；2nd, belt mud dewatering equipment：By up and down two tensioning strainers entrainment of
Sludge blanket, it is S-shaped from roll-in cylinder to pass through, form squeezing to sludge blanket by strainer tension force itself and shearing force realizes sludge
Dehydration；3rd, Centrifugal sludge dehydration machine：Sludge sends into rotating cylinder by hollow rotating shaft, is dumped into rotary drum intracavitary immediately under centrifugal force,
Sludge is transported to the tapered end of rotary drum by the continuous discharge in outlet under the promotion of auger conveyor；The liquid of pendular ring layer is then by weir
Mouth continuous " overflow " is drained into outside rotary drum by gravity discharge；4th, Die Shi sludge dewatering equipments：By retainer ring, travelling ring is layered on top of each other, spiral shell
The filtration body that spin axis is formed therethrough；5th, spiral pressing dehydrator：The screw rod of spiral pressing dehydrator is arranged on by filter screen
In the cylinder of composition, the entrance from dehydrated raw material is gradually thicker to Way out screw body diameter, between screw rod blade
Volume taper into, dehydrated raw material is also gradually compressed.
However, sludge dewatering equipment on the market is arranged on middle part due to water hole, when two filter press plates are separated, bottom
Filter cloth is still bonded on filter press plate and can not separated, and causes the sludge of filter cloth lower end difficult for drop-off, results in blockage.

Embodiment
Referring to figs. 1 to Fig. 5, the present invention is a kind of dewatering and filtering mud equipment of easy desliming, including pressing filter box and is set side by side
Put and filter membrane 2 is provided between some eardrum plates 1 on pressing filter box, adjacent eardrum plate 1, each lower end of eardrum plate 1, which is additionally provided with, to be passed through
The water hole 3 of eardrum plate 1 is worn, the lower end of filter membrane 2 is fixedly installed on the eardrum plate 1 of the bottom of water hole 3, is additionally provided with push-and-pull each
The motor 4 that eardrum plate 1 is moved.
By the way that water hole 3 to be arranged on to the lower end of eardrum plate 1, the lower end of filter membrane 2 is fixedly installed on the drum of the bottom of water hole 3
On diaphragm plate 1, when pulling open recovery normal position by motor 4 after the extruding sludge of eardrum plate 1, eardrum plate 1 drives each filter membrane 2 whole
Body tilts and then all shakes off by the sludge cake after moisture is extruded on filter membrane 2, and what middle part was set compared with prior art crosses water
Hole 3, it is to avoid filter membrane 2 is bonded on water hole 3 that to cause the bottom of filter membrane 2 not tilt dirty to shrug off bottom when eardrum plate 1 is separated
It is the problem of mud, simple in construction, with low cost.
During work, motor 4 promotes the eardrum plate 1 of side and then promotes each extruding of eardrum plate 1 sludge, is driven after extruding
Motor 4 pulls eardrum plate 1 and then each eardrum plate 1 is pulled open into certain distance, and each eardrum plate 1 recovers normal position, because of adjacent eardrum
Filter membrane 2 is provided between plate 1, the sludge shaken when each eardrum plate 1 is opened on filter membrane 2, filter membrane 2 is shaken off.
As preferred embodiment, each lower end of filter membrane 2 is additionally provided with the first projection 23 for putting in water hole 3.
The position of first projection 23 is corresponding with the position of water hole 3, each after each eardrum plate 1 is extruded by motor 4
When eardrum plate 1 carries out extruding sludge, the sewage being squeezed out is discharged by water hole 3, each eardrum plate 1 and filter membrane 2 when making extruding
