Abstract
The invention discloses a filter plate structure of a non-membrane-type pressure filter, which comprises at least one filter unit, wherein each filter unit comprises two filter plates, an elastic pressing frame is arranged between the two filter plates, and the elastic pressing frame and the filter plates are sealed. When the pressure filter is a box-type pressure filter, a support plate is arranged between the two filter plates, a filter chamber is formed between the filter plates and the adjacent filter unit, the elastic pressing frame comprises pressing movable frames and springs, the pressing movable frames are connected with the ends of the filter plates, and the two ends of the spring are respectively propped against the two pressing movable frames and pass through the support plate. The filter cake formed by filtration is compressed and pressed under high pressure and ultrahigh pressure by the filter plate structure of the invention, the filter cake bridging strength formed during the filtering process of the material is overcome to reach the critical pressure for pressing, thereby the subsequent processing link of the whole filtration can be reduced, the operation cost of the process is reduced, meanwhile more power consumption also can be reduced, and malfunction is not easy to occur because single hydraulic pressure is adopted as a pressure source.
Description
Technical field
The present invention relates to a kind of filter press.
Background technology
Filter press is a kind of intermittent filtering separation device, carries out the Separation of Solid and Liquid operation, is applicable to industry widely.Filtration theory develops densification and squeeze bifurcation theory after the eighties in last century, former common plate and frame filter press changes over chamber-type press filter along with being subjected to densification Theory Influence and development of technology, and the filter pressure that it can bear is higher, the filter cake density of filtering the back generation is bigger, and water capacity more reduces; Especially be subjected to the influence of German van-type diaphragm pressing filter press filter board the nineties again, pay attention to the development of Technology in Pressing, adopt rubber or plastic diaphragms (air pressure or hydraulic pressure) squeeze and filter, the cake dewatering amount of formation is better.As in the environmental protection industry (epi) of mud discharging, reduce oven dry filter cake technical process energy consumption, to play the positive role of energy-saving and emission-reduction, reduction environmental pollution.
Filter press is for applying the machinery that mechanical force realize to be filtered in filter medium one side, be divided into horizontal, chamber-type press filter and plate and frame filter press, vertical type blotter press, belt filter press etc.The structure of filter press is made up of three parts: frame, hold-down mechanism and filter mechanism.With the chamber-type press filter is example:
Frame comprises: (a) thrust plate: it is connected with bearing one of filter press sat up straight drops on the ground, the thrust plate of chamber-type press filter is intermediate feed hole (other position is also arranged) mostly, four angles also have four holes, last two jiaos hole is cleaning solution or squeezing gas feed (also can do filtrate (liquid in the filtration period), and two jiaos are outlet (free flow or undercurrent structure being arranged as filtrate or cleaning solution outlet) down; (b) pressure strip: in order to compress filter plate, filter frame, the roller of both sides moves on the track of crossbeam in order to the support compression plate; (c) crossbeam: be supporting member,, can select coatings such as fiber glass resin, polypropylene, stainless steel coating or new anti-corrosion coating according to the requirement of environment for use corrosion-resistant.
Hold-down mechanism comprises that hand screw compresses, mechanical compaction, hydraulic pressure compress.With the mechanical compaction is example: hold-down mechanism is made up of motor (overload protective device that configuration is advanced) decelerator, gear pair, screw mandrel and hold-down nut.When compressing, motor just changes, and drives decelerator, gear pair, and screw mandrel is rotated in Fixed Nut, promotes pressure strip filter plate, filter frame are compressed.When thrust is increasing; the motor load electric current increases, and when arriving the current value of protector setting greatly, reaches maximum thrust; motor is cut off the electricity supply; stop operating,, can guarantee the impaction state in the course of work reliably because screw mandrel and Fixed Nut have reliable self-locking helical angle; when returning; motor counter-rotating, the briquetting on pressure strip is return when pressing travel switch and is stopped.
Filter mechanism is made up of filter plate, filter frame, filter cloth or squeeze diaphragm plate.Filter cloth is a kind of main filter medium, the selecting for use and using of filter cloth, filter effect there is conclusive effect, will be when selecting for use according to the pH value of filter material, factors such as solid particle size select for use suitable filter cloth material and aperture to guarantee low filtration cost and high filter efficiency, during use, guarantee that filter cloth is smooth not give a discount that the aperture is unimpeded.The filter plate both sides are coated by filter cloth, and when needing the configuration squeeze diaphragm, one group of filter plate is made up of diaphragm pressing plate and corresponding filter plate.The substrate both sides of diaphragm plate are coating rubber or plastic diaphragms, and the barrier film outside is coating filter cloth, and filter plate is common chamber filter plate.Material enters each filter chamber from the charging hole on the thrust plate, and solid particle is trapped within the filter chamber because of the aperture of its particle diameter greater than filter medium (filter cloth), and filtrate is then flowed out from the fluid hole of filter plate below.When filter cake need drain, remove and enter the barrier film interlayer with liquid, gas, filter plate is imposed outside the mechanical force diaphragm pressing, also available compressed air or steam from washing mouthful feeding, with the air-flow displacement, are taken the moisture content in the filter cake out of, to reduce the moisture content of filter cake.
Existing filter press is cake layer work principle of filter (and flowing through filter), and the square root of filtration flux and filtration time is inversely proportional to, and filter cake thickness reaches and is directly proportional with the time square root by the liquid cumulative volume.Along with the prolongation of filtration time time, the filter cake of filter medium face thickens, and resistance strengthens, and the rate of filtration slows down, and filter pressure increases, and finishes until filtering.The stratum granulosum skewness of cake layer (the medium face is to filter cake) forms the fine grained filtering layer, causes filtration difficulty, and filtration time prolongs, and filter pressure increases.
From to rubber or plastic diaphragms filter press operating position, use the field of this technology constantly to enlarge, because the social desirability of green low-carbon, to filtering and squeezing proposition requirements at the higher level, but there are many deficiencies in prior art and product, because barrier film is thin and be subjected to the restriction of material property, the obstacle that existence can't be gone beyond aspect heat resisting and pressure resisting etc.; Production complexity and complex operation, service life is not long; Maintain and replace accessory valency height, needing in addition increases water, gas energy equipment needed thereby, pipeline facilities etc., has increased expense and energy consumption.
Summary of the invention
