Description
Technical field
The invention belongs to technical field of environment protection equipment, and in particular to a kind of filter roller of belt press filtration sludge filter press.
Background technology
Waste water control occupies an important position in environmental protection industry (epi), and the first step of waste water control is that sewage is filtered,
And the sludge to filtering out carries out press dewatering, existing sewage water filtration band filter, to reduce equipment volume, deposits mostly
It is few in pressure roller, the problem of squeeze force is small, cause that the moisture content of the cake after squeezing is high, and mud cake is unfavorable for transporting and stored, also influences
To sludge subsequent treatment, while due also to belt type filter process is disposable filtering, so the water quality after filtering is relative containing dirt
Amount is big, and band filter thickener used and belt filter press are all used separately both at home and abroad, and floor space is big, cost
Height, using effect are poor.
Existing belt press filtration sludge filter press by sludge and certain density flocculant be sufficiently mixed in a mixer with
Afterwards, the minute solid particles in sludge are condensed into the larger floccule mass of volume, while isolate Free water, and sludge is transported to concentration
On the strainer of gravity dehydration, the sludge of not flow regime is formed under gravity, then is transported between two strainers, is passed through
Under precompressed, low pressure and the ascending extruding force of high pressure, shearing force, progressively extrude sludge, with reach maximum mud,
Water separates, and eventually forms filter cake output.
But when sludge in precompressed, low pressure event, due to filter roller and strainer between contact be all face contact, cause mud,
Water separation is not smooth, have impact on water outlet efficiency.
The content of the invention
The utility model provides a kind of press filtration for belt type sludge filter press for being capable of rapid dehydration and filters roller.
The technical solution of the utility model is：
Roller is filtered in a kind of press filtration for belt type sludge filter press, and press filtration filter roller is hollow spline, hollow spline press filtration
Filter roller is made up of hollow, multiple circular reinforcing bars separately.
Further, above-mentioned press filtration filter roller is radially provided with reinforcement.
Further, above-mentioned reinforcement is 3.
The beneficial effects of the utility model are：
First main pressure roller is designed using linear contact lay, forms Points replacing surfaces, so as to improve pressure water operating efficiency.Material enters pressure
During power area, material in area's interior edge strainer, constantly strengthen forward by operating pressure, and material is squeezed volume contraction after power, contained
Free water reaches saturation state, when it is squeezed by linear contact lay, goes out water speed and accelerates 3~4 times of increase.

Embodiment
Under be further described with reference to accompanying drawing：
Referring to accompanying drawing 1, Fig. 2；Fig. 1 is the press filtration filter roll structure schematic diagram of hollow spline, and hollow spline filter roller 1 includes
20 circular reinforcing bars 102 are formed, and 3 reinforcements 103 that are transversely provided with of circular reinforcing bar 102 are used to strengthen hollow spline filter roller 1
Intensity, bearing 101 is used to hollow spline filter roller 1 be fixed on the frame of filter press.
Referring to Fig. 3, Fig. 4, belt type sludge filter press machine is broadly divided into A areas, B areas and C areas：
A areas are from gravity dewatering period
Mainly the sludge after waddingization is evenly distributed on strainer through cloth bucket, sludge is fed forward with strainer, after flocculation
Free water flowed out under Gravitative Loads by strainer, main function is to slough the Free water in sludge, makes the mobility of sludge
Reduce, prepared for extruding in next step.The second strainer that the area is used to convey after separating by the second guide roller set 61 conveys.
B areas are mainly precompressed dewatering period
Sludge mobility after gravity dehydration has almost been lost, with the operation forward of machine strainer, upper lower filter belt away from
From being gradually reduced, it is to extend the gravity dehydration time that material, which starts by ascending extruding force, the effect of tapered region, increase wadding
The extrusion stability of shape material, to be prepared into higher-pressure region.
Tapered region includes the first guide roller set 51 and the second guide roller set 61, the first guide roller set 51 be used to conveying after separation the
One strainer, the second defeated mud strainer that the second guide roller set 61 is used for after conveying separation, the first defeated mud strainer and the second defeated mud strainer
The crossed belt press filtration roller 7 of joint forms a wedge-shaped press filtration region.The wedge formed by the first defeated mud strainer and the second defeated mud strainer
Shape press filtration region applies extruding force to sludge, carries out pre- press-dehydrating, to meet filter-press dehydration to sludge liquid content and mobility
It is required that.
C areas high pressure dewatering period
Hollow spline filter roller is designed using linear contact lay, forms Points replacing surfaces, so as to improve pressure water operating efficiency.Material enters
When entering pressure area, material in area's interior edge strainer, constantly strengthen forward by operating pressure, and material is squeezed volume contraction after power, institute
The free water contained is extruded to form filter cake output, so far completes whole processing procedure.
First press filtration roller of the present utility model is the engineered rear dehydration concerted effort of hollow spline filter roller 1 by original about 10
Ton hour brings up to 40 ton hours.
Referring to Fig. 5, the area is high pressure dewatering period partial enlarged drawing, wherein the area it is main be precompressed dewatering period the first defeated mud filter
Band and the second defeated mud strainer are after the merging of crossed belt press filtration roller 7, and the first defeated mud strainer and the second defeated mud strainer band are entrainment of sludge, warp
Enter respectively after hollow spline filters roller 1, the second press filtration roller, the 3rd press filtration roller, the 4th press filtration roll-in filter after one guide roller 8
Separated in two outer power rollers after driven roller 5, lower driven roller 6.
Now sludge abjection is transported to sludge conveyer belt；First defeated mud strainer and the second defeated mud strainer are included by multiple respectively
First deflector roll 51 and the second deflector roll 61 convey the first strainer and the second strainer respectively.
Wherein the second strainer is used for the sludge for conveying A, B area, in the strainer of B areas first and the second strainer through wedge-shaped press filtration region
Enter high pressure dewatering period through a guide roller 8 after merging.
The effect of guide roller mainly regulation strainer enters the angle of hollow spline filter roller 1.
Applicants have discovered that hollow spline filter roller 1 enters roller angle for 15 °, go out roller angle for 5 ° when water outlet it is most fast, be
Optimum implementation.
Go out the roller angle and the roller angle of entering of the 4th press filtration roller of 3rd press filtration roller are respectively 45 ° and -45 °；4th press filtration roller
The roller angle that goes out to be -30 ° be also optimum implementation.
Angle of the present utility model refers to level angle.
Operation principle
After sludge and certain density flocculant are sufficiently mixed in a mixer, the minute solid particles in sludge coagulate
The larger floccule mass of volume is polymerized to, while isolates Free water, sludge is transported on the strainer of concentration gravity dehydration, in gravity
Effect is lower to form the sludge of not flow regime, then is transported between two strainers, by wedge-shaped precompressed, low pressure and high pressure by it is small to
Under big extruding force, shearing force, sludge is progressively extruded, to reach the mud of maximum most fast degree, water separates, and eventually forms filter
Cake exports.
