The utility model has the advantages that the sludge dewatering equipment not only has the largest capability for treating the sludge to press and filter the vast majority of water in the sludge, but also can prevent from the generation of extrusion leakage.
Description
Technical field
The utility model relates to a kind of device for dehydrating sladge waste that is used for Treatment of Sludge, belongs to device for dehydrating sladge waste and dewatering process and makes the field.
Background technology
CN201198463Y, title " device for dehydrating sladge waste " comprising: the slurry conveying machine structure (3) that is used to carry pending water-containing sludge (9); The distributor gear (4) that joins with described slurry conveying machine structure; At least one admits the container from the mud of described distributor gear, and described at least one container can seal and variable volume; Pressing mechanism (6) is used for the water-containing sludge of squeeze receptacle; Pressure exerting arrangement (5) is used for described pressing mechanism is exerted pressure; Described pressing mechanism comprises a plurality of apart from one another by the movable stripper plate of opening (16), and described at least one container is flexible filter bag (17), and each filter bag (17) is placed between the isolated stripper plate, and the opening part of each filter bag is provided with closing device.Its weak point: the one, dewatering efficiency is low; The 2nd, dehydration rate is low, the energy consumption height.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design and a kind ofly can improve dewatering efficiency effectively, can improve the device for dehydrating sladge waste of dehydration rate again effectively.
Design: in order to realize above-mentioned purpose of design.1, the setting of flocculation agitator is one of technical characterictic of the present utility model.The purpose of doing like this is: because the application has long inclined gravity dehydration district, be distributed on the guipure by feeder through the mud after the flocculation treatment, owing to designed enough length, thereby the fluctuation of charging mud had bigger ability to bear, this district has certain appropriate inclination angle, impel the free water that is synchronized with the movement with filter screen to reflux, prolonged the time of staying of treatment media, guarantee to filter as far as possible many free moistures in the gravity district.The characteristics of doing like this are: the consumption of a. flocculant reduces, and operating cost reduces.B. drainage area increases, and bearing capacity strengthens, and disposal ability improves.C. to various material handlings,, make this district's tail end output shaping material at the free water of this stage equal energy filtering more than 80%.D. the race mud of having avoided entering compression roller squeezes the leakage phenomenon.2, forcing the design of extruding transfer passage, is two of technical characterictic of the present utility model.The purpose of doing like this is: the one, through the mud in gravity dehydration district, before entering crush zone, must carry out fully pre-press-dehydrating to it, otherwise under the situation of crush zone pressurization suddenly, the mud of thickness can be squeezed from the strainer both sides to leak and leak, the mud that this tapered region unloads the gravity district is slowly clamped, it is carried out order precompressed thickening lentamente, the free moisture of remnants in the mud layer is minimized, along with slowly advancing of two guipures up and down, article two, the distance between the upper and lower of guipure reduces gradually, and middle mud layer hardening gradually forms a blob of slag.The characteristics of doing like this are: a. makes the belt filter press operation more reliable and more stable, and disposal ability becomes to maximum.B. avoid pushing the generation of leakage.Two is upper-lower position sequence alternates of two strainers, to powerful extruding, the shearing force of filter cake generation of clamping, the moisture overwhelming majority that remains in the mud is squeezed the press for extracting juice filterings.This plot structure compactness has reduced the length of strainer, reduces the cost of complete machine.3, the filter cloth conveyer belt that is positioned at filter cloth connecting gear top be provided with cleaning device and by water pump, valve and pipeline to the design that cleaning device supplies water, be three of technical characterictic of the present utility model.The purpose of doing like this is: the utility model adopts two to overlap independently rinse-system, is respectively applied for the cleaning of lower filter belt, and band all adopts backwash mode up and down, water consumption is low, effective, the high pressure nozzle of structure uniqueness is distributed in the airtight water tank, and flushing is convenient.
Technical scheme: belt squeeze type filter, it comprises main frame and pressing device, described pressing device is provided with flocculation reactor, the flocculation reactor bottom is provided with feeding opening and mud inlet, the flocculation reactor outlet is directly to the folder of the filter cloth in filter cloth conveying mechanism dewater unit, last strainer transmission closed-loop path and lower filter belt transmission closed-loop path sequence alternate are arranged to constitute and are forced the extruding transfer passage, and last strainer transmission closed-loop path and lower filter belt transmission closed-loop path are respectively equipped with strainer cleaning bucket and lower filter belt cleans bucket.
The utility model is compared with background technology, the one, the setting of flocculation agitator, not only the consumption of flocculant reduces, and operating cost reduces, and drainage area increases, bearing capacity strengthens, disposal ability improves, and to various material handlings, at the free water of this stage equal energy filtering more than 80%, make this district's tail end output shaping material, the more important thing is that the race mud of having avoided entering compression roller squeezes the leakage phenomenon; The 2nd, force the design of extruding transfer passage, not only make the belt filter press operation more reliable and more stable, disposal ability becomes to maximum, most the squeezing of moisture that remains in the mud can be pressed filtering, and avoid pushing the generation of leakage.
