Description
Technical field
The invention belongs to technical field of environment protection equipment, and in particular to a kind 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 press dewatering is carried out to the sludge filtered out, existing sewage water filtration band filter, to reduce equipment volume, is deposited mostly
Few in pressure roller, the problem of squeeze force is small causes the moisture content of the cake height after squeezing, 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 is 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 isolating Free water, 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 is separated, 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 present invention provides a kind of belt press filtration sludge filter press for being capable of rapid dehydration.
The technical scheme is that：
A kind of belt type sludge filter press, including frame, the drive device being arranged in frame and electrical control gear, the first defeated mud
Strainer and the second defeated mud strainer and press filtration roller, the first press filtration filter roller are hollow spline, and hollow spline press filtration filters roller by hollow
, multiple circular reinforcing bars separately constitute.
Preferably, above-mentioned circular rod is 20, and reinforcement is 3.
Preferably, the roller angle of entering of the defeated mud strainer of above-mentioned first press filtration filter roller is 15 °, and the roller angle that goes out of defeated mud strainer is
5°。
The beneficial effects of the invention are as follows：
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 area
When, material in the area along strainer, constantly strengthen forward by operating pressure, and material is squeezed volume contraction after power, and contained is 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 bar 102 is constituted, and 3 reinforcements 103 that are transversely provided with of circular reinforcing bar 102 are used to strengthen the strong of hollow spline filter roller 1
Degree, bearing 101 is used to hollow spline filter the frame that roller 1 is fixed on 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 from
Flowed out by water under Gravitative Loads by strainer, main function is to slough the Free water in sludge, reduce the mobility of sludge,
Prepared for next step extruding.The second strainer that the area is used to convey after separation by the second guide roller set 61 is conveyed.
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 distance by
Tapered small, material starts by ascending extruding force, and the effect of tapered region is the extension gravity dehydration time, increases floccule
The extrusion stability of material, to be prepared into higher-pressure region.
Tapered region includes the first guide roller set 51 and the second guide roller set 61, and the first guide roller set 51 is used to convey the after separation
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 wedge-shaped press filtration region of the formation of crossed belt press filtration roller 7 one of joint.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 pressure
During power area, material in the area along strainer, constantly strengthen forward by operating pressure, and material is squeezed volume contraction after power, contained
Free water is extruded to form filter cake output, so far completes whole processing procedure.
First press filtration roller（Hollow spline filters roller 1）Water separation capability increases to 40 by 10 original ton hours after the transformation of structure
Ton hour.
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 strainer and
Second defeated mud strainer is after the merging of crossed belt press filtration roller 7, and the first defeated mud strainer and the second defeated mud strainer band are led entrainment of sludge through one
After filtering roller 1, the second press filtration roller, the 3rd press filtration roller, the 4th press filtration roll-in filter through hollow spline respectively after to roller 8, into outside two
Separated in power roller 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 that hollow spline filters 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.
The angle of the present invention refers to level angle.
Operation principle
After sludge and certain density flocculant are sufficiently mixed in a mixer, the minute solid particles in sludge are condensed into
The larger floccule mass of volume, while isolating Free water, sludge is transported on the strainer of concentration gravity dehydration, in the effect of gravity
It is lower to form the sludge of not flow regime, then be transported between two strainers, it is ascending by wedge-shaped precompressed, low pressure and high pressure
Under extruding force, shearing force, sludge is progressively extruded, to reach that the mud of maximum most fast degree, water are separated, filter cake is eventually formed defeated
Go out.
