Machine.
Background technique
Belt filter press is also referred to as belt mud dewatering equipment, by strainer, roll-in cylinder, strainer clamping system, strainer deviation system,
Filter belt flushing system and strainer drive system are constituted.Working principle is: water-containing sludge is separated, and is delivered to sludge through sludge pump
Agitator tank, while adding flocculating agent and carrying out being sufficiently mixed reaction, the cloth mud device of belt filter press is then flowed into, sludge is uniformly distributed
It dredges onto gravity dewatering zone, and in the two-way of mud rake under gravity, sludge is sloughed rapidly with the movement of dehydration strainer
The free water of sludge.Since gravity dewatering zone design is longer, to reach gravity dehydration to greatest extent.The sludge overturn into
The wedge-shaped precompressed drying zone for entering overlength slowly clamps the sludge that gravity area is unloaded, and forms the angle layer of sandwich style, to its into
Row sequence is slowly pre- to increase press filtration, and the residual free moisture content in mud layer is made to reduce to minimum, with upper and lower two strainers it is slow before
Into the distance up and down between two strainers is gradually reduced, and intermediate mud layer is gradually hardened, and passes through the filtering of pre- press-dehydrating major diameter
Roller takes off a large amount of free water, can smoothly enter into extrusion dehydration area for mud cake, into S-shaped squeeze section, in S-shaped squeeze section,
Sludge is sandwiched among upper and lower two layers of filter cloth, is squeezed repeatedly through several pressure roller, and upper and lower two strainers are by each roller that interlocks
When the wave path of formation, due to the upper and lower position sequence alternate of two strainers, shearing force is generated to the mud cake of clamping, it will be remaining
The moisture overwhelming majority in sludge, which is overstock, to be filtered out, and promotes mud cake to be dehydrated again, finally by fiber, nylon or plastic scrapers
Dry mud cake is scraped, sludge storeroom is transported to by belt conveyor or Shaftless screw conveyor.
Traditional belt pressure filter for sludge dewatering, the tensioning of upper and lower strainer is realized by four sets of cylinder movements, by air
Compressor provides gas source；Once selected air compressor and cylinder model specification, cylinder are exactly to the tensile force of idler roller strainer
One constant force, such filter press have certain limitation to sludge dewatering.It is de- that the size of strainer tensile force directly affects sludge
Moisture content size after water is the vital technical performance index of belt filter press.Mechanism filter-pressing section strainer is made in constant-tension
Under, the specific gravity of sludge, the concentration of sludge, variation of sludge quantity etc. when sludge cannot be according into mud in continuous dehydration
Situation and automatically adjust strainer tensioning dynamics.Since sludge pump is when aspirating the sludge of sedimentation basin or sludge-tank, into mud concentration
The inconsistent thick dilute or calcic having having is containing sand containing biggish sludge of specific gravity such as heavy metals.Become continuous processing process not
Stablize, leading to that treated, moisture percentage in sewage sludge height is unstable.It not can determine that sludge components, specific gravity are aqueous before selected filter press
The factors such as rate, tensile force is exactly definite value after selecting traditional belt filter press, to the adaptive poor of field condition variation, in reality
It is arisen a problem that during border processing sludge press filtration: as inputiing mud volume and strainer tensile force (can not adjust) are certain: dilute into mud
Thin sludge (moisture content is high), causes sludge from strainer both sides " running mud "；Dense sludge (moisture content is low), causes tension inadequate
Keep mud extraction moisture content high；Further dehydration subsequent to sludge or power generation by waste combustion etc. are very unfavorable.
