Description

Filter press unload the filter press that cake washes cloth mechanism and method and uses this mechanism
The present invention relates to be used for the filter press of Separation of Solid and Liquid, what be specifically related to filter press unloads wash cloth mechanism and unload the cake method that washes cloth of cake, and has this wash cloth filter press of mechanism of cake that unloads.
As everyone knows, filter press comprises hold-down mechanism, fixation clip, the guide rail that connects hold-down mechanism and fixation clip, drive the movable pressing board that the lower edge guide rail moves at hold-down mechanism, be arranged in the most filter plates that can move along guide rail between fixation clip and the movable pressing board, 1 of filter plate or 2 faces are filtering surfaces and cover with filter cloth, vertical filter plate (filtering surface is perpendicular to the ground) along continuous straight runs of horizontal pressure filter is arranged on the guide rail of level, can move by along continuous straight runs, the horizontal filter plate (filtering surface is parallel to ground) of vertical type blotter press vertically is arranged on the vertical guide rail, can vertically move.Promote movable pressing board with hold-down mechanism before filtering and compress all filter plates, filtering surface annular sealing surface is all around compressed mutually, the space within annular sealing surface forms airtight filter chamber.The suspension that is filtered during filtration enters filter chamber by feeding-passage, the liquid that promotes in the low suspension liquid at pressure sees through filter cloth, flow out filter press through groove on the filter plate filtering surface and filtrate channel, solid in the suspension forms filter cake among being trapped in filter chamber by filter cloth, stops the charging press filtration when the suspension inlet reaches suitable degree.Then according to concrete service condition and requirement, to specific technologies such as filter cake wash, squeezes, dries up.Must draw back the filter cake in the filter plate removal filter chamber after whole technical process finishes, just can repeat above-mentioned technical process, also want regular cleaning and regeneration filter cloth.Removal filter cake and clean filter cloth by hand, not only labour intensity is big, and poor working environment, and need take very long machine time adds long-time cycle, has reduced the production capacity of machine significantly, so people make every effort to realize unloading cake wash cloth mechanization and automation.Createed and diversifiedly unloaded the cake mechanism that washes cloth, yet followed these mechanisms and what come is more mechanical breakdown, increased maintenance work, innovation is further improved.
When unloading cake, a kind of filter press draws back filter plate with special-purpose drawing-plate mechanism block-by-block, drawing back the hanging apparatus that filter cloth is installed on the every filter plate behind the filter plate opens, at this moment with a mobile vibration body rapping filter cloth that is positioned at the filter plate top, the filter cake that is attached on the filter cloth is come off.Block-by-block draws back after the every filter plate removal filter cake successively, pushes all filter plates round about with hold-down mechanism, and then draws back every filter plate with the drawing-plate mechanism block-by-block, at this moment with the sparge pipe block-by-block flushing filter cloth that moves.The advantage of this filter press is that filter plate quantity can be many, total filter area of filter press can be done greatlyyer, shortcoming is that the rapping filter cloth can not the big filter cake of the clean stickiness of removal, cause charging press filtration hourglass material even material spray unavoidably, it is that the block-by-block filter plate hockets that arm-tie and rapping filter cloth unload cake, it is long to unload the cake holding time, unloads to repeat block-by-block after the cake once more to draw back the shared time of filter plate flushing filter cloth longer, has therefore reduced the production capacity of machine significantly.US Patent specification US-3622005 (announcing in 1971) and US-4129137 (announcing in 1978) describe this filter press in detail.
The horizontal filter board type filter press that US Patent specification US-3342123 (nineteen sixty-eight announcement) describes uses the very long annular filter cloth of a monoblock, and filter cloth is walked around many guide rollers that are installed on the filter plate and interted between filter plate, covers on the filtering surface of filter plate.When unloading cake with hold-down mechanism with draw back chain all filter plates are drawn back certain interval, then with a concentrated filter cloth driving mechanism traction monoblock walking of filter cloth, by means of the walking of filter cloth with filter cake from transporting between the filter plate and unloading, in the walking of filter cloth process, filter cloth is cleaned with a concentrated device that washes cloth.The advantage of this method be unload cake and the mode that washes cloth more effective, can be in the short time the whole filter cakes of removal, shortcoming is that the length of filter cloth is big, filter cloth bears very big tractive force to overcome the walking of filter cloth drag overall, need to use special filter cloth, filter cloth is costly, cleans whole filter clothes and need grow distance walking filter cloth, the length that expends time in, long filter cloth wanders off in the process of walking easily.
The piecemeal filter cloth that the disclosed filter press of US Patent specification US-3807567 (announcing in 1972) uses two vertical filter plates of filtering surface and can walk, every filter plate is equipped with the walking of filter cloth device and unloads the cake device that washes cloth, when unloading cake with hold-down mechanism with draw back chain whole filter plates are drawn back, drive the walking of filter cloth device of whole filter plates then with prime mover and special transmission mechanism, drawing all filter clothes walks simultaneously with the removal filter cake, unload the filter cloth of walking repeatedly again after the cake, wash filter cloth in batches.The shortcoming of this scheme is that drawing all filter clothes with shared prime mover and transmission mechanism walks simultaneously, this need draw back whole filter plates simultaneously, because filter plate quantity many (for example 50), the total kilometres that draw back filter plate are very big, and the gap of drawing back between the filter plate is not enough big, unavoidable knot arch was blocked between the filter plate when filter cake fell from draw back the gap, hindered walking of filter cloth; Again since the filter cloth that prime mover will drive whole filter plates walk simultaneously, therefore its overload moment of torsion is much larger than the bearing capacity of the walking of filter cloth device of every filter plate, when certain piece filter cloth generation walking disorder, the overload moment of torsion of prime mover is enough to destroy the member of walking of filter cloth device; Unload the filter cloth of walking repeatedly after the cake in addition, washing whole filter clothes need take a long time in batches, prolongs the filter press work period.
The filter press that US Patent specification US-4155830 (announcing in 1979) describes is that every single-filtering face filter plate uses an annular filter cloth separately, every filter plate is equipped with the walking of filter cloth device and unloads the cake device, the whole filter plates of disposable tension when unloading cake, drive the walking of filter cloth device of every filter plate then by special transmission mechanism with a prime mover, drawing all filter clothes walks simultaneously, walking removal filter cake by means of filter cloth, push and compress whole filter plates after unloading cake, feed the water backwashing filter cloth that washes cloth from feed pipe, and then draw back whole filter plates, draw the walking of filter cloth reposition.This filter press also exists and above-mentionedly draws back filter plate entirely and a prime mover draws the problem that all filter clothes are walked and brought simultaneously, and in addition, the flushing filter cloth need repeat to push and draw back filter plate, and the time that washes cloth is long, and water consumption is big.
First purpose of the present invention is to provide a kind of cake mechanism that washes cloth of independently unloading for filter press, not only can effectively unload cake washes cloth, and tractive force is little during walking of filter cloth, clean filter cloth time weak point, in when, in the walking of filter cloth process obstacle taking place, unload the member that cake washes cloth in the mechanism and be unlikely to wreck, reduce maintenance load.Second purpose of the present invention is to provide a kind of new cake method that washes cloth of unloading for filter press, so that suitably strengthen the gap of drawing back of filter plate, prevent that filter cake is blocked between the filter plate, eliminate failure factor, improve functional reliability from another aspect, reduce to draw back the total kilometres of filter plate simultaneously, shorten the length of machine, give full play to new the wash cloth advantage of mechanism of cake of unloading.Another object of the present invention is based on above-mentioned the wash cloth mechanism and unload the cake method that washes cloth of cake of independently unloading, and provides that several structures are complicated and simple to differ, and performance differs from one another, and the new type pressure filter that the scope of application is different is to satisfy the needs of different user.
Realize unloading that cake washes cloth is a kind of more effective way by means of the walking filter cloth.Because filter plate quantity is many, the thickness of filter plate is little, and needs mobile filter plate when unloading cake, and the restriction of supporting technology condition, got used to adopting a continuous filter cloth of prime mover traction monoblock in the past, and also adopted a prime mover when using the piecemeal filter cloth by complicated transmission mechanism traction piecemeal filter cloth.Facts have proved that because the poor working environment of filter press, the walking of filter cloth process breaks down unavoidably.And these can easy eliminating fault often cause unloading the wash cloth damage of mechanism of cake.The walking resistance and the tractive force of every block of filter cloth greatly reduce when using the piecemeal filter cloth, but prime mover of centralized driving still needs to draw whole filter clothes (for example 100 blocks of filter clothes), its overload moment of torsion and stall moment of torsion unload the wash cloth bearing capacity of mechanism of cake much larger than an independent filter plate, when the moment of certain piece filter cloth generation walking failure, overload moment of torsion of prime mover and stall moment of torsion will unload the wash cloth parts of mechanism of cake easily and destroy, and be day after the fair even control system is reacted.In order to reach first purpose of the present invention, the present invention's design drives continuous filter cloth centralized driving or the piecemeal filter cloth centralized driving that replaces in the past with the dispersion of piecemeal filter cloth, and a kind of new cake mechanism that washes cloth of independently unloading separately is provided.This mechanism comprises: be installed in walking of filter cloth device on the every filter plate, unload the cake device, the device that washes cloth, drive prime mover of walking of filter cloth device.Prime mover has suitable shaft rotating speed, moment of torsion and braking function, can be to have the motor of deceleration device, motor, hydraulic motor or other power set at a slow speed.
