Specific embodiment
In existing belt type dehydration device, most common is two kinds, and one is squeezed by parallel opposite pressing roller up and down
Then pressure is dehydrated roll assembly dehydration by S-shaped, in this type of design, pressure is essentially identical in other words for tension everywhere, does not have
Cross, cause to be easy to appear the phenomenon that running mud when starting to squeeze, while the moisture content of sludge reduces suddenly, cause roll gap pressure and
Frictional force increases, and the strainer stress in front is big, and the strainer stress at rear is small, is easily destroyed strainer, while reducing the filter in front
Tape running speed.Another kind is that two-stage compresses up and down, after the compression of the first order, sludge fall after in the second level.In this design
In, every grade requires two groups of strainers and corresponding conveying device.Bulky, energy consumption is high, and sludge is being fallen in second level filter
When band, second level strainer is caused to impact, strainer service life is short.Two stages of compression above and below simultaneously, causes it in spatial distribution
It is highly larger, other supports and control assembly are needed, structure is complicated.It is there are one extremely important problem, when sludge is fallen,
Its shape is loose, and moisture content is lower, therefore when entering in second and strainer, will cause uneven, the compression of different places
Dynamics is different, unevenly, influences final efficiency.
As shown in Figure 1, including into bucket 1, pre-treatment area 2, drying zone 3, sludge discharging area 4, going out mud plate 5 and conveying roller group 6.
Drying zone includes the first drying zone and the second drying zone first, and continuously distributed, i.e., strainer is straight from the first drying zone
It tapping into the second drying zone, the sludge in strainer and strainer seamlessly transits between two drying zones, rather than from the first drying zone
Strainer on be detached from after enter back into the second drying zone.Strainer overlapping between first drying zone and the second drying zone, sludge are located at
Between strainer.Each strainer is the entirety of a closed loop, is driven by a feed roller assembly.In the first drying zone, take off
Damping roller at least two, and along the direction that sludge enters, radius sequentially reduces, on the first dehydration roll, wrap angle sigma >=200 ° of strainer.
Cornerite refers to, along the strainer direction of motion, the angle of strainer and tangent two points of dehydration roll to line between dehydration roller center.By
In sludge characteristic (hydraulic loading or solid content etc.) if pressure crosses flood and has little time to filter out from the two sides of strainer when fluctuation, meeting
Occur running mud phenomenon to both ends.200 ° of big cornerites, can generate dehydration technology region, it is ensured that most of water is entering the second dehydration
It has been sloughed when region, has avoided the phenomenon that mud is run at filter bag both ends under big pressure condition.Meanwhile a progressive pressure can be provided,
Avoiding increasing pressure suddenly causes the pressure between strainer point and dehydration roll excessive, it is caused to occur being similar to and be bonded in dehydration
Phenomenon on roller causes one tension of strainer on both sides big, and a tension is small, and tension is big to be torn, and tension is small, compresses
Inefficient, and be easy to run mud.For being greater than 180 ° of cornerite, when concordant between preceding processing area and the first dehydration roll, filtered water

Drying zone；Second drying zone includes at least three the 4th dehydration rolls, and the ratio of the 4th dehydration roll and third dehydration roll radius is (1
± 0.1): 1.
According to mechanics principle, pressure is directly proportional to tension, is inversely proportional with radius, meanwhile, the movement velocity of strainer, i.e. linear speed
It spends identical, in order to obtain preferably squeezing effect, needs to strainer speed, pressure etc. is designed.In a preferred embodiment,
It is preferred that radial design exponentially is successively decreased, such as n*n:n:1, n is real number, then pressure is 1:n:n*n, forms index and increases.?
When water content is more, hydraulic pressure can be gone out by lesser pressure, as moisture is fewer and fewer, the pressure needed can be increasingly
Greatly, in such a way that pressure is incremented by, strainer caused by the too fast removal of moisture can not only be solved and be tensioned, service life is short to ask
Topic, also improves water outlet efficiency.
