Description
Technical field
The utility model relates to a kind of solid-liquid separating equipment, particularly a kind of continous way filter press.
Background technology
Filtration is a chemical enginnering process the most basic.Usually be that the interception part is handled slurry with the filter cloth, the liquid under the effect of external force in the slurry becomes filtrate by the filter cloth duct, and the solid particle in the slurry is trapped within becomes filter cake on the filter cloth, thereby realizes Separation of Solid and Liquid.
The traditional filtering machine is representative with plate and frame filter press and rotary drum vacuum filter.Plate and frame filter press mainly is made up of frame, filter plate, filter frame and hold down gag etc., and plate and frame are done quadrate more, and left and right corner all has circular hole on filter plate, the frame, assembles and compress the duct that the back constitutes Flow of Goods and Materials, and the both sides of frame form the filter chamber coated with filter cloth.Slurry enters the filter chamber during filtration under certain differential pressure action, and filtrate is converged discharge from the bottom, and filter cake is stayed in the filter chamber, treat that filter cake is full of the filter chamber after, namely stop to filter.Rotary drum vacuum filter mainly is made up of rotary drum, dispensing head, slurry tank etc., the rotary drum outer surface is made of porous plate, filter cloth covers thereon, rotary drum inside is separated into several not connected fan-shaped lattice chambers, each lattice chamber has the interior duct of pipeline and hollow shaft to be connected, and the duct in the hollow shaft feeds on the rolling disc that is positioned at axle head and rotates with the axis vertically, rolling disc and fixed disk closely cooperate becomes dispensing head, be divided into several arc grooves on the fixed disk of dispensing head, communicate with vacuum tube, washing lotion groove, compressed air line respectively.When rotary drum turned round, because the effect of dispensing head just forms vacuum or pressurization respectively in the fan-shaped lattice, controlled filter was operated carrying out smoothly of each stage.
Plate and frame filter press intermittently operated of the prior art, efficient is lower; Rotary drum vacuum filter relies on to vacuumize and is motive force, and differential pressure is limited.
The utility model content
The utility model provides a kind of rotating disc type pressing filter, and is little with the filter motive force that solves continued operation in the prior art, and the problem that the big filter of motive force can not continued operation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of rotating disc type pressing filter is characterized in that: comprise slurry import, gas feed, top cover, middle rotating disk, sealing plate, separator strip, chassis, filtrate (liquid and filtered solid outlet.Having the duct on the top cover is connected with slurry import, gas feed respectively, on the duct on chassis coated with porous plate and filter cloth, be connected with filtrate (liquid and filtered solid outlet respectively again, top cover and chassis all maintain static, middle rotating disk is rotated between top cover and chassis continuously by actuator drives, rotating disk is divided into several fan-shaped cavities in the middle of described, and the separator strip between the fan-shaped cavity and top cover and chassis form several sealed compartments.
A kind of rotating disc type pressing filter of the utility model, it is further characterized in that: preferably 16～24 of described fan-shaped cavities, preferably 16～24 of described sealed compartments.
A kind of rotating disc type pressing filter of the utility model, it is further characterized in that: form on the rotating disk separator strip in the middle of the sealing between described each sealed compartments is pressed in by the sealing plate on top cover and the chassis.
A kind of rotating disc type pressing filter of the utility model, it is further characterized in that: the rotating speed of rotating disk can be regulated by gear in the middle of described, and being generally 30～60 changes/hour.
A kind of rotating disc type pressing filter of the utility model, it is further characterized in that: the material of sealing plate can select for use metal or nonmetallic materials to make.The material of filter cloth can select for use metal or nonmetallic materials to make.
When rotating disk rotates in the middle of transmission device drives, slurry begins to enter continuously each sealed compartments, under the promotion of operating pressure, most of filtrate in the slurry is passed the district of filter just filter cloth to filtrate (liquid, a small amount of filtrate goes to the press filtration district with sealed compartments, further press filtration under the gas pressure effect, and residue filtrate is passed press filtration district filter cloth and is pooled to filtrate (liquid, be trapped in filter cake in the sealed compartments and be rotated further filtered solid outlet and come off voluntarily by gravity, finish the filtration operation.
The filter that the utility model provides, but continued operation, rotating speed is low, good airproof performance, filter area significantly improves, and filter capacity significantly strengthens, and has dwindled the specification of traditional filtering machine greatly, saved occupation area of equipment, be applicable to that petroleum chemical industry, fertilizer industry, plastic industry, rubber industry, pharmaceutical industry etc. have any one technical process of the requirement of filtering.
Description of drawings
Fig. 1 is the front view of the utility model rotating disc type pressing filter;
Fig. 2 is the vertical view of the utility model rotating disc type pressing filter.
Reference numeral shown in the figure: the import of 1-slurry, 2-gas feed, rotating disk in the middle of the 3-top cover, 4-, 5-chassis, 6-filtrate (liquid, 7-filtered solid outlet, 8-porous plate, 9-filter cloth, 10-transmission device, 11-fan-shaped cavity, 12-separator strip, 13-sealing plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model rotating disc type pressing filter is described in further detail.
