Abstract

Filter of the present invention is in one screw to be arranged, earlier in order to behind the automatic slag removal in order to the filter of squeezing pressurization and deslagging; It also has thin wing shape filter mechanism and other fine structures.Because automatic discharge, can make that the residual quantity of filter residue is a substratum on the filtering surface, greatly reduced the resistance that filters, simultaneously, thin wing filter mechanism provides the large tracts of land of filtering, and the two combines, and makes operation not only automatically continuously but also high filter efficiency arranged.

Description

The present invention is a kind of large tracts of land filtering surface that has, and can approach the equipment that filter cake layer filters by automatic discharge.

Filter operation be chemical industry, food, etc. the important means of production of many industries, but with regard to its equipment, also some important defective waits to overcome, as most of filter plants deslagging voluntarily, can not the serialization running; Can automatic discharge, mostly be vacuum filter greatly, need join the big vacuum equipment of power consumption, and also extreme difference of efficient; Certainly, utilize huge automation equipment and technology auxiliary filtration apparatus also can realize continued operation running, but that is actually with automation equipment and remedy defective on the filter plant; In addition, also has the spiral filter plant, propose for No. 835465 as No. 3919087, U.S. Pat and Russian Patent, though can the automatic discharge serialization use, but the characteristics of these two patents all are extremely to be similar to general pressafiner, can only handle denseer material, can not adapt to various situation (material that for example contains a large amount of juice) purposes and be subjected to limitation.Through research repeatedly, finished originally intact bright at the problems referred to above thereby found out the way of dealing with problems.

Purpose of the present invention just provides a kind of the simplest and easy suitable, can serialization automated operation, have thin filter cake layer strainability and have very big filter area, power consumption is few, take up an area of little high efficiency filter plant.

See on the whole, this filter plant, all be penetrated with screw mechanism from head to tail, forwardly mainly be usually to filter, spiral plays convey materials, at the rear portion then is screw press, the filter residue that the front portion is filtered squeezes one time again, dewatering high score from state in the hope of reaching height, and connect the interlude anterior and rear portion, is for example cutting back of super helix pumping action of a trifle pump housing, the effect of this pump housing cutting back is to filter very thick filter residue to be pressed into the screw press position at rear portion with filtering through the front portion, because filter residue is without when squeezing, though thickness very, they are moisture still a lot, on helical blade, slide easily, can make the rotation pressurization of spiral not have due effect, that is to say very easily slippage of material, if but inject via the pressurization of one section pump housing such as helicoidal pump cutting back, make the possibility of its slippage reduce to minimum scope, just can at regular time and quantity material (filter residue) be sent into the rear portion by the front portion along with the rotation of spiral, it has played the effect that guarantees pressurization.

The present invention has used a seed wing shape filter in addition, and its characteristics are exactly to have great filter area in minimum space, thereby the filter capacity of this machine of making has raising.

The detailed explanation of making comparisons respectively of now just anterior again, rear portion and middle interconnecting piece position.

The present invention is a continuous automatic fitration equipment, system is anterior by a central rotary mechanism with spiral impetus and scraper effect, cooperate the interior filtering surface garden tube filter mechanism that adapts with it, with the rear portion be one section little shape pressafiner, accompany for example cutting back of super helix pumping action of a bit of pump housing through the centre, the three joins end to end and forms.Simultaneously, the formation of this machine, most of parts form by less unit combination, can dismantle or open, with these factors the filter plant of feature.

The infusion pump of establishing in addition outside by machine when material, band is pressed when pumping into the material that will filter in the machine, having filter residue immediately appears in the tube of machine chamber, at this moment through the rotation of screw mechanism, constantly filter residue is scraped stripping and promotion, with the material of not filtered, carried backward, further through pressure filtration, forwardly filter when finishing, the big dehydration of material, the congee shape thing of formation thickness, the pump housing such as helicoidal pump cutting back rotation pressurization through the middle part, inject the press section at rear portion by force, after squeezing, reach high dewatering state, form more dried filter residue and be pushed outside the discharge machine, thus embody this machine when filtration high score from usefulness.

The garden tube of filtering surface garden tube filtration fraction in above-mentioned, it can be whole, also can be that segmentation is joined end to end by plural unit joint and organizes biography, unit joint itself is equally.Both can be whole also can by the junior unit of two (or more than) half garden tubes (or garden watt shape) piece together to and form.The purpose that combines with junior unit is to be convenient to dismounting or unlatching, so that maintenance and repair and replacing.Have the window that filters usefulness on the barrel, be equipped with on the window can filtration filter block, this filter block can be opened in movable dismounting.

Filter block is to be overlaped with the thickness wire netting (or nonmetal net) of supporting it by filter cloth (or other filter medium) and 1～several layers and nationality, and be embedded on the framework, so form the device of a semicircular tile shape in order to filter, the size of its size and above-mentioned window is suitably under the situation of using sealing strip, filter block is installed on the window periphery requires to be provided with leakage when filtering, the net of filter cloth on this filter block and support filter cloth is not limit the material and the number of plies, support the held concurrently effect of infusion channel of the net of filter cloth, the filter that is filtered off is molten to flow to collector tube through it, again the outflow filter section.

In order to enlarge filter area, we dislike the filter course area that only has one deck semicircular tile shape curved surface on the filter block too little, thereby allow its filtering surface strengthen and to spatial spread, so we have created a kind of device that is referred to as to filter wing, so-called wing is meant a kind ofly have the object as thin as a wafer of upper and lower surfaces (as shark's fin, pinion), and filter wing is by the extremely smooth supporter of a kind of drain, supporting two filter courses (cloth) up and down, stretch and immerse in the material that is filtered, in order to the device of filtration,, filter area will be heightened if be installed on the filter block, increase several times so that tens of times, form powerful filter capacity, the filtration wing also can have peripheral frame or the built-in skeleton in order to reinforce, and nationality is to support, take up space with institute so that fix its installation position, in order to avoid crooked damage causes fault.

The filtration wing soaks to be stretched in the slurries that are filtered, because it is subjected to balanced hydraulic pressure, and can not show the phenomenon of its pressurized, be able on supporter as thin as a wafer, supporting simultaneously two very big filtering surfaces, this filtration wing, fitly be arranged on the implements of filter block or other filtration usefulness, form huge filter capacity, and filter between the level and line-spacing of wing, form the place that filter residue accumulates, with special stirring filter residue is pushed away to eject, can realize that then thin filter cake layer filters and running continuously.This special stirring can replace with filtering wing, i.e. the movable wing that will address of back.

The another kind of form of filtering wing supports with rigging, i.e. on the wall of cartridge filter (actual is on the filter block), select out suitable position, earlier from wherein first, hang a tightrope between 2 of the second, outside these 2, look for 1～several points again, continue suspension cord, with earlier in first, 2 ropes that hanged of second, link together and form a slice network, each point on this network is preferably in the same plane, in order to support two filtering surfaces and the wherein folded charges that take up the usefulness that supports filter cloth and water conservancy diversion filtrate up and down, this has just formed the filtration wing that a slice is supported by rope, can make this filtration wing of multilayer with quadrat method, these filter the different levels of wing, should be parallel to each other and appropriate intervals is arranged, so that the interaction of movable wing and fixed wings is not bumped against, certainly, combine with metal (or nonmetal) the skeleton supporter of filter made wing of rope is also passable, that is to say, movable wing also can and be installed on the helical axis with its composition, utilize the advantage of rope, be to make the filtration wing more thinner, lighter, as long as unobstructedly that the filtrate derivation is just passable in order to support filter cloth and energy, this will make the number of plies of filtering wing increase, and greatly enlarges filter area.

Present device can also be used a kind of hollow stent in order to carriage filtration wing, and available tubing system is to lead filtrate outflow.Promptly on the filter block of main shaft and cartridge filter, install this support, can support in a large number by different level and as required, be arranged in rows or spiral helicine filtration wing, use this other side's in the ranks fixedly filtration wing and movable wing separately that be interspersed in mutually, make the filter that has larger cross-sectional area (promptly very thick), can install the filtration wing thick and fast equally, filtration wing used herein then should not be too wide, but the cripetura distortion becomes approximate bar-shaped filtration wing, in order to avoid the mutual overslaugh in the running.

Because the interspersed effect that is used is just bigger between fixed wings and the movable wing, thereby need to install by different level, this be pursue efficiently necessary, but the mode that still can find some install to arrange makes is installing or during some position of demolition filter, can with regard to the monoblock filter block or helical axis carries out, carry out and needn't be one by one support and wing be taken, only rotate the position of a lower main axis where necessary a little, can abdicate approach in place separately, dismounting still is very easily so.

Present device, can quote a kind of filter cloth with folding crape tiny pocket, in order further to enlarge filter effect again, we can also be on the surface of filter cloth, make a large amount of tiny pockets that is communicated with filter layer of cloth, as if many folding crapes have appearred on filter cloth, also also can derive the material institute filling of filtrate in the tiny pocket with supporting tiny pocket upper and lower surface filter cloth, so the chorion that forms on the similar human small intestine is such, can enlarge the implements of absorbing surface, the usefulness of filtration is further enlarged along with the increase of area.

Folding crape tiny pocket easily makes filter residue come off from filter cloth, also beneficial to reducing resistance, just when filtration contains the material of fine particle, have the brand-new filtering surface of parts of fine microparticle by filter residue having been come off fully, enter in the filtrate, make the filtrate muddiness, this will note a matters such as using method and tiny pocket length size shape.

Use the chain that dangles under the filtering surface.The saturation of filter area has been brought up to a new level though filter wing, but in order to prevent the mutual collision between wing and the wing, we must make it bigger than normal at interval between determined filtration wing, this just makes filter residue remaining on the filter cloth still dislike slightly thick, approach zero in order as best one can the resistance of filter residue to be reduced to, we can also adopt certain chain that dangles, as have the sectional small stuff or a snare of little weight, promptly on the filtration wing of last layer, fasten many (or multirows) this chain that dangles, when filtering, motion mutually between movable wing and fixed wings, scrape when picking mutually, because this chain that dangles can sink to crashing in the filter cake layer of its lower floor, along with the mutual motion between wing and wing, further scrape and get hold of residuing in filter residue on the filter cloth, thereby obtain to reduce the better effect of filtration resistance.

About screw mechanism (comprise in the machine before, in, after, portion), it is a main transmission mechanism in the machine, axle itself can be whole, also can be that segmentation is formed (or being connected to form) by more piece, the different piece of axle can be driven by a unified power, also can segmentation be driven by different drive apparatus, axis body both can be hollow, also can be hollow, or be sleeved on together by the different tubing of caliber size and use, the bore of hollow shaft hollow can be very big, wherein can insert the pipeline of water-through and ventilating, to heat or to cool off, can also interiorly lead to wash water to wash filter residue etc.

As for screw mechanism itself, its concrete form is along with different needs can change, for example spiral can be made up of solid vane, also can be hollow, or the spiral outer rim is continuous or discontinuous hurricane band, be fixed on the helical axis with stent support, itself can play the scraper effect these screw mechanisms, scrape stripping and promote filter residue, also can pacify scraper or brush thereon in addition only as support, in order to scrape or to brush the promotion filter residue, this scraper or brush available metal material and plastics, nonmetal manufacturing such as rubber, particularly it can also install the filtration wing with very big filter area, makes it both to work to scrape stripping and promotes filter residue, can play the effect of filtration again, the filtrate that it leaches can be via ad hoc pipeline, outside the hollow discharge machine via screw spindle.

As previously mentioned, in the equipment that filtering surface filters in the tube of garden, the position that filter block is arranged on the wall, can give prominence to again on the filter block and install the filtration wing, this filtration wing fitly is arranged in rows by different level, filters between the wing parallel mutually, every layer is filtered between the wing, all kept certain intervals, had a bit of space, this space is the place that accumulates of the filter residue that constantly produced by filtration.

We also address the filtration wing that is equipped with the effect that replaces scraper or brush on spiral simultaneously, this part filters wing with respect to the filtration wing of being fixed on the wall filter block, can be referred to as the active filters wing, this active filters wing is parallel being installed with fixing filtration wing, just between active filters wing and the fixing filtration wing, differ the height of half storey mutually, movable in other words wing is among layer that is inserted in fixed wings and the space that layer is separated by, we can say that equally, also fixed wings is the centre that is inserted in movable each layer of wing.

Arrange out a phase difference when between every layer of the movable wing, as a complete unit, movable wing is just as the blade of spiral, be arranged in a helical form, whenever its during by main shaft institute driven rotary, certainly also can present certain spiral impetus, still, this movable wing is between the fixed wings, in the process of rotation, it navigates within the space of fixed wings layer and interlayer just, the filter residue that fixed wings leached is pushed away discharge this space and enter among the passage that does not filter wing, as a same reason, in the process of rotation, begin the never position of fixed wings at movable wing, the fixed wings position is injected in rotation, the layer that enters fixed wings with layer the gap time, filtering the filter residue that the is produced wing that equally also is fixed by movable wing is stopped, wipe off, fall into the filter residue passage of no fixed wings, scrape stripping mutually between fixed wings and the movable wing like this, reject mutually, filter residue is remained on the filtering surface, an only remaining substratum, all the other all are pushed and drain into passage and delivered to next stage continuously and go to handle.

The exploitation that pushes owing to spiral, the filter residue that makes on the filtering surface to be accumulated is scraped stripping, filtering surface is brought in constant renewal in, this machine of making is when filtering, all the time be in thin filter cake layer and filter state, as everyone knows, the resistance of filter operation is mainly from long-pending more thick more filter cake layer in the general device, the usefulness that thin filter cake layer filters is to reduce resistance to raise the efficiency, and the peculiar active filters wing of this machine of employing spiral and the fixing wing that filters, filter area is heightened, and the filter area that its unit volume is held is far above general flame filter press, this thin filter cake layer filters and combines with large tracts of land, not only enlarged area widely but also greatly reduced the resistance that filters, the function that this equipment is filtered rises to a new height, has really formed high high-effect of machine little ability.

What connect anterior and rear portion in the middle of present device is a bit of pump housing, it for example can be a helicoidal pump cutting back, it is to establish the spiral segment by adding one or two (or more than) parallel and intermeshing thick tooth with main spiral in that main spiral is other, at this other end of establishing thick tooth spiral, be equipped with the driven gear that can be meshed with the travelling gear of on main helical axis appropriate location, installing, when main spiral rotates, gear on the axle also rotates the drive driven gear, make the other motion of spiral of establishing with main spiral, do synchronous rotation, make intermeshing spiral closely be cooperated rotation, so this section helicoidal pump cutting back filters out the front portion, sloughed the thickness congee shape material of a lot of moisture content,, injected the press section at rear portion at regular time and quantity by force along with the rotation of spiral.

Originally, material filters through the front portion has deviate from a large amount of moisture content, become leather hard, can on the propelling worm of rear portion, squeeze further dehydration, but there is dehydrating amount still to dislike not enough, material fluidity is big, and screw press does not have due effect sometimes, the empty rotation of helical blade, material is slippage thereon, and just having prevented this slip phenomenon by this spiral cutting back, material is injected the rear portion by force, for example effect of helicoidal pump cutting back of the pump housing that Here it is, owing to be not to be conceived to pressurization, so the helicoidal pump cutting back needn't be very long, but do not hinder pressurization to need yet, suitably extend this part.

Though other thick tooth spiral of joining is very short in the helicoidal pump cutting back, but also has excessive suspicion, that is to say that it can also further be simplified, method is replaced with end to end a string hemisphere ball retaining chain of being contacted with belt, in intermeshing part, replaced by the one or two hemisphere ball retaining that links to each other, remainder, be that unnecessary part all is simplified, but also can and go former necessary master from the nutating gear letter, the pressure from top to bottom that is produced when just rotating by main helical blade, drive can only keep off along the hemisphere ball that slide rail slides, make it to be in all the time the state that is meshed with certain one deck impeller of main spiral, impeller blade so in layer and the alternate rear of pressing to synchronously of the retaining of hemisphere ball one by one, through very short stroke, after having finished the effect of helicoidal pump cutting back, ball retaining hemisphere is along the slideway that returns, wraparound original place, behind from former slideway, nibble mutually so that cooperate with helical blade once more, move in circles like this and constantly move, in fact Here it is without the helicoidal pump cutting back with one of other pump housings example.

Certainly, the hemisphere of this ball retaining, its shape is can be diversified, is easy to use in a word, is not linked with material and is advisable.As for the selection of system hemisphere ball retaining, can do with multiple materials such as plastics, rubber, also can make and carry out slush moulding again or ward off rubber etc. of metal.The belt of polyphone hemisphere should be selected for use and is easy to detour on track, is difficult for folding or pleat crape and material that can anti-chemical corrosiveness and is the warp-wise softness and the hard special balata belt of broadwise.If use and to support also passable by rotating skeleton without belt.

The last position of present device is a pressafiner, seen through the filter course installed here by the squeezing filtrate of being extruded and outside the discharge machine, the filter course here both can be installed on wall, also can install on the main shaft between the helical runner sheet, filtrate directly or by screw spindle (filtrate that filter course leached on the axle) is gone out outside the machine by current drainage by ad hoc drain pipeline.

Aspect deslagging, slag-drip opening be provided with can pressure regulation pressure cover, with pressure regulation such as weight or springs.Make at the material incipient stage filtered or that get well without filter and be unlikely to directly to flow out outside the machine, just must could discharge through slag-drip opening through the dry material after abundant filtration and the squeezing, after running steadily, the pressure on the pressure cover becomes resistance, at this moment can take the pressure device of pressure regulation.

The filter pressure of present device forefront is from the outer infusion pump of machine, and it constantly will be with the slurries implanter inner filtration of pressure.

Connection between each unit of this equipment can be diversified, can straight line connects, also can be mutually different angles and connect, in order to increase filter area, can also with the mode of grafting or and the mode that connects enlarge filtration fraction.

Last this equipment has shell, and it both can solve smell and escape, and volatile matter scatters and disappears, again can be anti-pollution, can solve that water filling plays back flushing filter cloth etc. in shell simultaneously again.

The operation operation of filter of the present invention

1. close slag-drip opening earlier, and pressurizeed with the pressing mechanism of pressure cover, in case the material of filtered and filter is good as yet material from top to down the full machine of through-flow discharge from slag-drip opening.

2. before starting the filter rotation, will inject the material of filtration in the machine earlier, as long as along charging aperture, with the outer set infusion pump of machine the material pressurization is pumped into, because infusion pump institute applied pressure occurs in the machine and the outer pressure differential of machine immediately, thereby has begun the process of filtering.

3. whether have under the liquid drip at the bottom of at this moment noting seeing machine, if any, then explanation is positioned at the machine bottom, and the sound two partly sealing situation of junctions is bad, should stop charging immediately and repair, otherwise the bearing that can undermine the bottom causes other accidents.

4. could continue feed pressurization and filter when not having the 3rd said phenomenon, at this moment the pressure of charging aperture is not too high, because two sections pressurizations, the phase I does not require too big pressure, otherwise to a certain degree damage can occur to filter cloth.

5. in the material reader was arranged, filter mechanism comprised and filters wing and other filtering surfaces, has filter residue to occur immediately, at this moment should drive immediately, main helical axis is rotated, the one, can approach filter cake layer and filter, the 2nd, avoid late driving, because of filter residue is too dense, appearance is driven difficult and parts is caused damage.

6. filter the material after wing filters through front portion (top), its concentration is increasing, when arriving at the centre pump housing, has become to glue the congee state, at this moment the pump housing of middle part also in ceaselessly rotating, pressurizes these materials at regular time and quantity at any time and injects the screw press position at rear portion (bottom).

7. the dried filter residue behind screw press, continuous continuing is subjected to the pushing of spiral rotation, backs down the pressure cover of slag-drip opening and is discharged from, if at this moment deslagging is stable, water content also satisfies the standard of expection basically, so just can take the pressure apparatus that pressurization covers, to reduce the resistance drop low energy consumption of deslagging.

8. as required, when needing to add heating, should distinguish the control that (adding from the main shaft large caliber pipe mouth) facility aspect is added in situation control with cooling or washing filter residue wash water.

9. be in operation and note the situation that filtrate is discharged at any time; because leakage fluid dram is more; but no matter muddy phenomenon is arranged: just illustrate that a part of filter cloth has been worn or phenomenon appears unclamping in the edge of press seal filter cloth, answer hard stop to repair from that filtrate of flowing out flatly.

10. when the back flushing filter cloth, at first to stop the rotation of screw spindle,, influence the normal use of equipment in order to avoid filled the filter cloth that sticks out by counter-flow water by spiral or filter wing and scrape and pull.

Effect:

1. this machine filter pressure mainly relies on the outer infusion pump of machine, presses in the implanter with the material web that pump will filter, and its pressure is easy to be controlled at 2～3kg/cm ²Perhaps, this efficient that surpasses vacuum filter just far away;

2. the filter area held in unit volume of this machine far surpasses flame filter press, and the little ability of machine is big, is that flame filter press can not be by comparison;

3. because automatic slag removal is brought in constant renewal in filtering surface, can reach desirable thin filter cake layer and filter, usefulness is better than having other filters of same filter area;

4. the mechanism that squeezing is arranged once more, with generally filter the filtrate that is difficult to take out squeeze out can reach high score from effect;

5. owing to utilize infusion pump pressure filtration and energy automatic slag removal deslagging, make these facility that the performance of serialization automated production be arranged, the institute that has solved general filter can not;

6. use infusion pump pressure filtration, its energy consumption is far below vacuum filter etc., and the squeezing of second step is also because wet filter residue is little with the frictional force of helical blade, and it is not high to consume energy equally;

7. entire equipment is simple in structure, and most of parts all are detachable or open, and are easy to maintenance;

8. can heat and to cool off, can wash reversible flow flushing filter cloth, can airtightly keep clean, escaping in the time of to prevent volatile matter and handle poisonous material;

9. this machine can endwaysly use, and filter capacity greatly and floor space is very little is saved construction investment, can bring into play the benefit of plant area.

6. 6, the device of said expansion filter area promptly in claim 1, this filter plant can also use a kind of filter cloth with folding crape tiny pocket, in order further to enlarge filter effect again, we can also make a large amount of tiny pockets that is communicated with filter layer of cloth on the surface of filter cloth, as if on the filter cloth many folding crapes have appearred, in the tiny pocket also with supporting two-face filtering cloth on the pocket and can deriving the material institute filling of filtrate, so form chorion on the similar human small intestine that works the implements that enlarge absorbing surface, filtering efficiency is further enlarged along with the increase of area.
7. 7, the device that said thin filter cake layer filters in claim 1 comprises that this filter plant can also use a kind of chain that dangles, and is about to one section one section thin cord or snare that has little weight, tie up to and filter on the wing, when filtering, between movable wing and fixed wings, get into smooth mutually, scrape mutually and pick.Because this chain that dangles can sink and weigh down in the remaining filter cake layer of its lower floor, along with the mutual motion between wing, the filter cake layer that is stretched into further scraped get hold of, thus the better effect of acquisition reduction filtration resistance.
8. 8, said screw mechanism is (before comprising in the claim 1, in, the rear portion), its axle is a main transmission mechanism in the filter, axle itself can be whole, also can be that segmentation is made up of more piece (or mutually in succession), its different piece can be driven by a motive power, also can segmentation be driven by different drive apparatus respectively, axis body both can be solid, also can be hollow, or by the use that is nested together of the different tubing of caliber size, the bore of hollow shaft can be very big, wherein can insert water flowing, the pipeline of ventilation can also interiorly lead to wash water for washing filter residue etc. to heat or to cool off.
9. 9, said center convolution mechanism in the claim 1, its concrete form can change with different needs, for example spiral can be made up of solid vane, also can be hollow, or outer rim be continuous or discrete hurricane band, is fixed on the helical axis with stent support, itself can play the scraper effect these screw mechanisms, scrape stripping and promote filter residue, also can pacify scraper or brush thereon in addition only as support.In order to scrape, to brush filter residue, nonmetal manufacturings such as this scraper or brush available metal and plastics, rubber, particularly it can also install said filtration wing in the claim 3, make it both to work to scrape stripping and promote filter residue, can play a role in filtering again, its filtrate can be via ad hoc pipeline, outside spiral hollow shaft discharge machine.
10. 10, the pump housing of being carried secretly between said front portion and the rear portion in the claim 1 for example, helicoidal pump cutting back for example, it is to establish spiral by adding one or two (or more than) parallel with main spiral and intermeshing thick tooth in that main spiral is other, be equipped with the driven gear that can be meshed at this other end of establishing thick tooth spiral with the travelling gear of on main helical axis appropriate location, installing, when main spiral rotates, gear on the axle rotates, and establishes the driven gear of thick tooth spiral one end by above-mentioned being positioned on that drive is meshed with it.Make the other motion of spiral of establishing with main spiral, do synchronous rotation, make intermeshing spiral very closely cooperate rotation, so this helicoidal pump cutting back filters out the front portion, sloughed the thickness congee shape material of a lot of moisture content, inject the press section at rear portion at regular time and quantity by force along with the rotation of spiral, the helicoidal pump cutting back just for example, be to replace by the pump housing of other kinds, and the side in the said helicoidal pump cutting back is joined thick tooth spiral and also can be simplified, promptly replaced by end to end a string hemisphere ball retaining chain of contacting with adhesive tape, being engaged part has hemisphere ball retaining to work, remainder all is simplified, nor need top said being positioned on to join active and driven gear on the spiral with the side on the main helical axis again, but produced by main helical blade rotation, pressure from top to bottom drives, the a string hemisphere ball retaining of on certain track that, be with by a blade of taking turns in turn singly and mesh, after very short stroke through engagement, hemisphere ball retaining is driven by the belt chain, leave former dragging track, track and the path returned behind along original track, return home position separately more successively, begin new circulation, form as for the hemisphere retaining is can be diversified, its material with the belt of polyphone hemisphere is also chosen wantonly, only require that to play the effect that can simplify just passable, for example without belt with special can rotating skeleton also passable.
11. 11, said aftermost press mechanism in the claim 1, can establish filter course on the wall and on the squeezing axle, filtrate is respectively from wall or outside propelling worm axle discharge machine, have on the least significant end slag-drip opening in this section can pressure regulation pressure cover, guarantee bringing into operation stage filtered or can not overflow from slag-drip opening without the good material of filter, just think that material filtered dried, by screw press with the material roof pressure, producing stronger pressure backs down pressure cover and is discharged from, after running steadily, can remove the pressure that adds to reduce resistance.
12. 12, in the claim 1 said full machine by in preceding back three ones form, its top filtration fraction, the infusion pump that filter pressure is established outward in addition from machine, by pump with material implanter inner filtration with pressure, before the filter plant, in, connection between each unit, rear portion can be diversified, but straight line connects, and also can be certain angle mutually and connect, in order to increase filter area, can grafting install, also can several install side by side, before the filter, in, the rear portion all can be installed shell again with airtight, both can solve and prevent smell, the walk-off-loss of volatile matter, can prevent outside contamination again, and can solve water filling in shell, play the back flushing filter cloth.
