Description
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 have the filter press of this mechanism of cake.
As everyone knows, filter press comprise hold-down mechanism, fixation clip, connection hold-down mechanism and fixation clip guide rail, drive movable pressing board that the lower edge guide rail moves at hold-down mechanism, be arranged in 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, filter plate 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, liquid in the suspension sees through filter cloth under pressure promotes, flow out filter press through groove on the filter plate filtering surface and filtrate channel, solid particle in the suspension forms filter cake among being trapped in filter chamber by filter cloth, stops the charging press filtration when filter cake thickness reaches suitable thickness.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 vibration body rapping filter cloth that moves 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 unavoidably, it is that the block-by-block filter plate hockets that arm-tie and rapping filter cloth unload cake, it is longer to unload the cake holding time, unloads to repeat block-by-block after the cake once more and draw back filter plate and could wash filter cloth, and therefore washing filter cloth also needs to take the longer time.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 (announcing in 1967) describes uses the very long annular filter cloth of a monoblock, and filter cloth is walked around many guide rollers that are installed in the filter plate two ends 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 filter plate between the filter plate and unloading from filter cloth, 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 with prime mover traction monoblock filter cloth, filter cloth length is big, filter cloth bears very big tractive force to overcome the walking of filter cloth drag overall, need to use special filter cloth, clean whole filter clothes and need grow distance walking filter cloth, it is longer to expend time in.
The disclosed filter press of US Patent specification US-3807567 (1972 announce) uses two vertical filter plates of filtering surface, and each filtering surface of filter plate uses a filter cloth separately, and every filter plate is equipped with the walking of filter cloth device and unloads the cake device that washes cloth.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 when unloading cake, draw all filter clothes and walk 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, and 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, and 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, draw all filter clothes and walk simultaneously, by means of the walking removal filter cake 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, the reposition of traction walking of filter cloth.Also there be above-mentioned filter plate and problem that prime mover concentrates all filter clothes of traction to walk and brought simultaneously drawn back entirely in this filter press, and in addition, the flushing filter cloth need repeat to push and draw back filter plate, and the time that washes cloth is longer.
Can unload cake more effectively and wash cloth by means of the walking of filter cloth.Because filter plate quantity is many, the thickness of filter plate is little, and the position of filter plate is unfixing in addition, and the restriction of supporting technology condition, gets used to adopting a continuous filter cloth of prime mover traction monoblock in the past.When using the piecemeal filter cloth, also still adopt a prime mover to draw all piecemeal filter clothes (for example 100 blocks of filter clothes) by the transmission mechanism of complexity.This moment, the walking resistance and the tractive force of filter cloth greatly reduced, but overload moment of torsion of prime mover and stall moment of torsion unload the wash cloth bearing capacity of mechanism of cake much larger than the monolithic filter plate.Because the poor working environment of filter press, the walking of filter cloth process breaks down unavoidably.And the fault that these are not difficult to get rid of often causes unloading the wash cloth damage of mechanism of cake.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 improve reliability and the operating efficiency that filter press unloads cake and washes cloth, 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, carries out piecemeal filter cloth independent ambulation separately.
