Abstract

The utility model discloses a vacuum band type pressing filter which is composed of a hydraulic assembly, a pressing sucking filter, a slip motor, a feeder, a collector, an automatic anti-bias device, a filtering net, a vacuum pressure roller, etc. The utility model is also adapted to the dehydration of the mud juice of sugar refineries, the lees of breweries, the kaolin and materials with fibre hydrophile besides the ranges which are adopted by a band type pressing filter. The pressed water can be discharged into the vacuum pressure roller, avoiding the moisture multiple absorption of a solid fibre object, reducing the consumption of the power, overcoming the problem that the water content of the filter cakes after dehydration by a band type filter is high and breaking through the viewpoint of unable chamber separation in a minor diameter. Therefore, the workers need not to get into circular cylinders to separate the chambers with steel tubes. The utility model has the advantages of simple structure, low cost and high pump strength. The vacuum band type pressing filter provides a new process for the materials which can not be dehydrated at present.

Description

Vacuum band type pressing filter

The utility model belongs to a kind of vacuum belt press filtering machine.

At present, dewatering and filtering equipment miscellaneous is arranged both at home and abroad, belt filter press as Austria, Britain, Japan only adapts to mud, mixing sludge, digested sludge, activated sludge and coal essence mine dehydration, its cake moisture is more than 69%, cake moisture height after the dehydration is present dehydration equipment ubiquitous one big problem.Simultaneously, some vacuum suction filters need the workman to creep into the shortcoming of using the copper pipe locellus in the tube of garden in addition.

The purpose of this utility model is to make outside the scope that its deconditioning belt filter press adapted to, also can adapt to sugar refinery mud juice, the vinasse of brewery, everyly have hydrophilic material of fiber and a kaolinic dehydration etc., the water that the vacuum press for extracting juice roller mechanism that increases newly can make extruding come out in time enters in the vacuum furnace, avoid the solid fiber thing to repeat to absorb moisture content, reduced the consumption of power, thereby overcome the high problem of cake moisture after the band filter dehydration, make its water content can descend about 15--20%, handle the water content of filter mud calculates with sugar refinery vacuum suction filter, this filter mud water contains sugar part nearly 13--15%, one tame 2000 ton per day sugar refinery, pressing season can be voluminous sugared 270 tons by 140 days, mostly is country and creates 520,000 yuan.Simultaneously, break through in the small diameter tube can't locellus viewpoint, the workman need not to creep in the tube of garden and use the copper pipe locellus, has saved a large amount of non-ferrous metals, vacuum than at present single vacuum suction filter big tens times to hundred times, provide new technology to the material that can't dewater at present.

The utility model is by the hydraulic pressure assembly, squeezing and suction-filtering machine assembly, slip electric motor, dispenser, gatherer, automatic anti-deflection device, compositions such as filter screen and vacuum pressure roller, flute profile coagulation dispenser (1) is fixed on the frame, hydraulic tensioner (2) is by oil cylinder and advance oil extraction and chew, the oil resistant rubber bowl, O shape packer ring, piston, the stayed mast idler roller is formed, idler roller is welded into and is fixed on seamless pipe on the bearing block of hydraulic tensioner (2) stayed mast, make filter screen keep certain degree of tightness automatically, above filter screen, be equipped with and wash wire stitcher (3), wash wire stitcher (3) by valve and forming at the galvanizing pipe that axially is drilled with aperture, cleaning filter screen for press water uses, outside last automatic anti-deflection device (4) structure is identical with hydraulic tensioner (2), the photoelectricity adjuster also is housed, proportional and integral controller, given control valve, two rollers that device (5) is pressed in two roll-ins are contained on the bearing block of arm board, arm board is fixed on the frame both sides, supply pressure drains filter mud, vacuum is pressed roller (6) by dividing plate (27), vacuum chamber (28), partition plate (29), seamless pipe (30), (31), quill shaft (32), fixed head (33), movable friction plate (34), Antileaking plate compositions such as (35), pack into by quill shaft supporting and to be fixed on the frame behind the bearing block, axle head is equipped with sprocket wheel, drag two filter screens by slip electric motor (7) and make the complete machine running, gatherer (8) is by blade, set screw is formed and is fixed on the frame, vapour Xian pipe (9) is contained on the filter screen, its structure is with washing wire stitcher (3), vacuum is pressed roller (10) and is pressed roller (6) with vacuum, at each section of filter screen work compression roller (11) is housed, (15), (16), (17), (18), (19), except that work compression roller (11) is rolled into the garden tube is welded into steel plate, other is fixed on the frame with bearing block by seamless pipe two ends shaft, following the same automatic anti-deflection device of automatic anti-deflection device (12) (4), filter screen (13) is the polyester net of band inclined hole, compensated regulator (14) is tight because of on frame with bearing block, regulate the polarization of proofreading and correct filter screen with bolt, guide roller (20), (21), (22), (23), (24), (25), (26) all be fastened on the frame, the trend of filter screen is fixed with bearing block.

The utility model removes has filter press, outside the two-fold advantage of vacuum suction filter, also have three roll-ins to press the segmentation pressurization function, make dewatering more perfect, pressure is big, vacuumize, make about solid material moisture content decline 15--20%, simple in structure, reliability height, low cost and other advantages, break through again simultaneously in the small diameter tube can't locellus viewpoint, with present vacuum suction filter comparison, having overcome needs the workman to creep into the shortcoming of using the copper pipe locellus in the tube of garden, has saved a large amount of non-ferrous metals in the equipment processing and manufacturing, make cost descend 40---50%, suction intensity increases etc. greatly.
