Field.
【Background technology】
Belt filter press is a kind of separation of solid and liquid for being incorporated in the fields such as sludge dewatering, slag dehydration, paper pulp molding extensively
Device.Its basic process is to clamp materials by two filter screens to do serpentine locomotion along dehydration roll, by means of the tension force of filter screen by thing
Liquid in material squeezes out.The ring network of belt filter press in the process of running, suffered by each part on its guipure
Tension force is consistent, can not flexibly adjust the squeezing pressure of some specific press filtration roller, and side leakage, filter occurs in the prevalence of easy
The problem of cake solid content is low, for example municipal sludge solid content is only 20% or so.As an improvement, number of patent application
201510343569.2 " drum-type sludge pressing desiccation machines " describe a kind of drum-type sludge pressing equipment, employ multigroup next to pressing
Strengthen to the squeeze force of material, the problem of making up net belt for hydro-extracting own tension deficiency, this is easy to the material phase of dehydration for those
When effective, such as vinasse, waste sludge from paper mill etc..But subject matter existing for the equipment is：For the material that drainability is poor, such as

And the surface that negative pressure damping case 6 contacts with filter press cloth band 2 is opens fluted wear-resisting panel, negative pressure damping case 6 is taken out by regulation
Vacuum is inhaled to adjust the guipure tension force of the filter press cloth band 2 of entered dehydration roll and press belt 18, it is strong so as to adjust mud face pressure, bear
The surface that pressure drag Buddhist nun case 6 contacts with guipure uses high-abrasive material, such as ceramic panel, and groove or eyelet are provided with panel.It is negative
The advantages of pressure drag Buddhist nun case 6 is simple and easy, is seized every opportunity, and can remove the moisture of belt surface.
The guipure flush pipe 13 can keep the unimpeded of filter medium and cleaning, and the cleaning fluid liquid dish 20 is located at guipure
The lower section of flush pipe 13, the press belt damping roll 7, folded net damping roll 22 and damping are coated with high friction to pressure roller 24
Layer, and press belt damping roll 7, folded net damping roll 22 and damping are at least one end fills with skidding in the both ends of pressure roller 24
Put, braking device can there are ways to realize, for example ripe commercially available prod magnetic powder brake, Pneumatic clamping move device
Deng usable, it is preferred to use magnetic powder brake, can more accurate more flexible regulating brake force square.Braking device is adjustable
The localised tension of filter press cloth band 2 and press belt 18 is saved, so as to adjust squeezing pressure, the driving force of guipure driven rolls 8 is with detouring
The local pulling force that the resistance superposition " tug-of-war " of damping roll is formed is tensed, and the tensile force provides dehydration power, realizes pressure
Squeeze separation of solid and liquid.Pressed zone for two rollers to pressure, at least one end band in two rollers in the both ends of at least one
There is braking device, the localised tension of guipure either lining band is adjusted by brake apparatus, so as to adjust squeezing pressure.Net
The local pulling force that driving force with driven rolls 8 and the resistance superposition " tug-of-war " for the damping roll that detours are formed is tensed, this
Clamp force provides dehydration power, realizes squeezing separation of solid and liquid.The filtered solid outlet between driven roller 8 and guipure discharge rolls 9,
The loading and unloading material scraper 10 and lower unloader knife 11 are respectively provided at the upper and lower ends of filtered solid outlet 21.
The segmented damping press belt 26 to Liquid Penetrant is the endless belt that a tensile strength is big and deformation is small, to liquid
The local pulling force that the driving force of the driven rolls 8 of segmented damping press belt 26 of body infiltration and the resistance superposition of damping roll are formed
Tensed, the tensile force provides the extra dynamic dehydration power in addition to quiet tension force, and passes to filter press cloth band 2 and its institute
The material of clamping carries out lasting squeezing, realizes squeezing separation of solid and liquid.To the parameter of the segmented damping press belt 26 of Liquid Penetrant
It is required that and specific material：The Newton/millimeter width of tension force 50~500, optimization range are 100~300 Newton/millimeters.At 500 Ns
/ millimeter tension under, the longitudinal and transverse direction size deformation to the segmented damping press belt 26 of Liquid Penetrant is no more than 2%.It is right
The composition of the segmented damping press belt 26 of Liquid Penetrant should have enough string diameters for being not parallel to traffic direction, and these string diameters help
In the folded net of increase pressurization damping with damped part such as folded net damping roll 22 and damping to the frictional force of pressure roller roll surface 24, anti-on-slip
It is dynamic.Segmented damping press belt 26 to Liquid Penetrant can be metal or nonmetallic high intensity ring network, such as wire netting, can
Using herringbone steel wire, enough tension force can be both provided, 1~2 millimeter of horizontal stripe diameter, optimize 1.4 millimeters, wrapping wire 1~1.5
Millimeter, optimize 1.2 millimeters, material is stainless steel.Such as nonmetallic net again, resin, polypropylene fibre or nylon material can be used
High intensity herringbone weave net or spiral net, 0.8~2.0 millimeter of string diameter.
As the means of enhancing dehydrating effect, the progressive supercharging drying zone of cattle horn shape can be used, the drying zone at least one
Pressure Independent adjustable to pressure roller and a damping roll, damping roll can be to the pressure damping roll or damping roll that detours.Ox
Angle is dehydrated the operation principle of passage：Material falls on damping press belt impervious to liquid and the wedge shape of strainer formation through distributing device
Area, pressed zone is entered under the driving of pressure roller, pressed zone space is gradually reduced along dehydration roll surface arc, and formation one is similar
The dewatering press passage of cattle horn shape.Pressure roller are provided with the end of pressed zone, the pressure roller can provide 50~2000N/MM line
Pressure, by taking 200 millimeters of opposite roll press section width as an example, the pressure of ox horn road end is 0.25~10.0MPA.Traditional common two pairs of rollers
The pressure of squeezing is only effective in the contact surface of two rollers, and the greatest drawback of two pairs of rollers squeezing is exactly to contact faciostenosis, such as, two are straight
Footpath is that 800 millimeters of roller pressed zone effective length is only 300 millimeters.Unlike the squeezing of common two pairs of rollers, this practicality
It is new to use segmented damping press belt, the property wrapped up by pressure zone will be delivered to by segmented damping press belt to pressure pressure
Material, if cornerite is 180 degree, a diameter of 800 millimeters of dehydration roll, then pressed zone effective length just has 1256 millimeters, is tradition
More than 4 times of two pairs of rollers squeezing design.In this pressed zone, bigger closer to two pairs of rollers squeezing point pressure, material water ratio is also got over
Low, accordingly, the relative movement resistance inside material is also bigger, pressure due to the inside moving resistance effect of material in material
And decay, it is higher to pressure suffered by the nearer material of pressure roller, it is lower from pressure suffered by the material more remote to pressure roller, then pressing
Squeeze in passage and naturally form the mechanism being pressurized gradually, high-moisture percentage material is dehydrated through low pressure, and low-water-content material is through high pressure
Strong dehydration, this is completely the same with dewatering process requirement, because more dry material needs higher pressure to be dehydrated, instead
It, the higher material of moisture content only needs relatively low pressure to be dehydrated.In order to which pressure is squeezed in more flexible control, can be set multiple
The progressive supercharging drying zone of cattle horn shape is divided into the progressive supercharging drying zone of multiple small cattle horn shapes, as needed by damping to pressure roller
Adjust the pressure in each area.
