1, not only there is core equipment designed by this patent, while a kind of technique has also been devised, this technique is very crucial, can
Guarantee the technological effect of material dewatering, the former does not have.
Except the core equipment of this patent and the former difference:
Although filter press (just disclosing before the former) 2, can be cried, because of this structural principle of filter press and title
It is unprotected before the former, for the mode generallyd use.But the design and the mode of the former filters pressing are different, Qian Zheyou
Expressing process has membrane filter plate, and the design does not have because diaphragm squeezing link have for this technique and equipment it is certain negative
It influences, also takes up the regular hour, dehydrating effect is bad, so the design does not have.
1), the former, which illustrates, is pan feeding and air-dries in opposite side, downside water outlet, the pan feeding of the design is more flexible, be can be
The heart is also possible to some position of filter plate, is also possible to outer frame, because this is not technical essential, where is feeding inlet setting
Enter to be ok, as long as material can be sent into material filter chamber.
2), the former air intake vent and air outlet opposite sides, the design think to be easy to cause funny road and isolated island in this way, and
The structure of filter plate is not illustrated.The main technical points of the design: the several steps of this process point, one carries out cloth wind, filter plate first
Provided with cloth wind channel, when wind is entered behind filter cloth, it is not through filter cake first, but carries out cloth wind, passes through the logic of pressure difference
Control, allows wind to be distributed evenly in filter cake surface.Two then allow again wind with pressure permeation to filter cake at a slow speed, balanced among,
The channel stablized, uniformly, complicated is formed among filter cake.Three, again by the adjusting of pressure difference, allow the pressure that penetrates of wind to be greater than between filter cake
Resistance, wind flows through filter cake by channel.The moisture of material, the Interstitial Water being mainly present between the particle of material dissociate
The water of the surface chemistry of water and material absorption, as long as by these removing moistures, so that it may play dehydrating effect.So originally setting
One technical essential of meter is that dry wind is required not only to flow through filter cake from the side of filter cake, also to flow through filter cake from side,
The circulated air that single filter chamber and entire chamber space are variously formulated in different time, it is main by controlling different air intake passages
Variation with pressure difference is realized.
3), the former does not illustrate that wind enters filter chamber is how to move towards, and does not illustrate the structure of filter plate yet.Because of different filters
The hardened filter chamber being configured to is irregular shape, in order to allow each position of filter cake side to have dry wind to flow through separately from side
Side, so the air inlet filter plate of the design all devises air intake passage on each side, filter plate is equipped with support stud, dry wind warp
It crosses after air intake passage enters filter chamber, entire filter chamber side is covered with from the gap of stud behind filter cloth, due to the effect of pressure difference, wind
There are four stage, cloth wind, infiltration, turbulent flow, circulations in filter chamber and filter cake.Originally, wind will not flow to another from the side of filter cake
Side, this stage are named the cloth wind stage, then according to the effect of pressure difference, wind at a slow speed, it is balanced, equably penetrate among filter cake,
The channel stablized, uniformly, complicated is formed among filter cake, this stage is penetration stage.By the adjusting of pressure difference, the wearing of wind is allowed
Saturating pressure is greater than its resistance being subject to, and wind flows through filter cake by the channel that second stage is formed, this stage is the turbulent stage.So
The air quantity and pressure for changing inconsiderate region again afterwards, circulate wind in chamber space, this stage is the cycle stage.
Separately the water outlet and air outlet of the design is same, on the downside of filter plate or some angle of downside.
4), the former does not illustrate that wind enters the export direction that filter chamber is, it is under filter cloth that the wind of the design, which enters filter chamber,
Fang Shuiping is blown into, and is directly blown on filter cloth, can protect in this way filter cloth do not blown it is bad.
5), the former has gas-guide tube, and the design does not have, and filter is worked as in each piece of hole for being all provided with different function according to the technological requirements
When plate compresses, this some holes is formed the channel of a congenerous.
6), the former returns that blow be to play drying function, the returning of the design blow master be will be in order to the material in feeding pipe be blown
It returns in material barrel.
7), the former does not illustrate the thickness that filter chamber is formed between filter plate is how many, can form more thick filter cakes, because into
The filter chamber of wind short circuit easy to form, the design can be with >=25mm, this depends primarily on the grade composition of material size, filter cake
Thickness can be adjusted by increasing or decreasing filter frame, the former does not have.
8), there is drainage hole on the former each piece of filter plate, drained outward in pressure-filtering process, the design does not have drainage hole, water
It is discharged with the steam with moisture from drainage channel, is separated subsequently into steam-water separator, in the lower section or left and right of filter plate
It is that will not there are flowing out, this avoid water to enter dry material system below equipment.
9), the design is additionally provided with wind, filtrate cycle interface in the lower side outer frame side of each piece of filter plate, and two interfaces are used
Valve is installed in transparent hose connection additional, to adjust the circulation or observation vapour, water state of dry wind, can also observe filter at any time
Whether cloth damages, and can see whether to have completed dehydration under equipment hand-guided state, the former does not have.
10), how the design is determining the completion of pan feeding link, first is that reach setting time by time setting and just stop,
Second is that passing through, the flowmeter of pan feeding or drainage pipeline, flow just stops pan feeding when being reduced to setting value, third is that according to being arranged whole
Weighing sensor on machine just stops pan feeding when weight does not change or the amplitude of reduction reaches setting value, the former does not have.
11), filter cloth adds vibrating mechanism, after the completion of each discharging, will vibrate to filter cloth, to prevent material viscous
It is not unloaded on filter cloth only, cause to damage filter plate or reduces processing capacity, this device is mainly disposed to not be that center pan feeding is set
Standby upper, the filter cloth overwhelming majority is not fixed.The former does not illustrate.
12), using by hydraulic cylinder, in centre, push-and-pull can also be from two layback selection structures for the filter plate folding of the design, the former
Only intermediate push-and-pull.
3, the temperature that the former mentions air-dried gas can be 60 DEG C~100 DEG C or 100 DEG C~200 DEG C, because at this moment one
The temperature of normal dry materials, without feature, but does not illustrate how drying, this link is critically important, is related to dry benefit.
The design air drying process is divided into two links, if air-drying temperature is higher than environment temperature, the air-dried high temperature that is divided into is air-dried, cold to go to air-dry
Two links are to carry out air-dried, air-dried certain time using the air (the design is 20 DEG C~200 DEG C) of certain temperature first
Afterwards, then with gas at normal temperature it is cooled down, material secondary water suction after the exit will not be made in this way, cause the reduction of drying effect, it is preceding
Person does not have cooling procedure.If air-drying temperature is exactly ambient air temperature, only one link of air drying process is exactly that room temperature is blown
Dry process.If causing energy loss because the material after doing can get damp when the temperature of dry material is higher than environment temperature and air-drying
Effect is poor.
4, the former does not illustrate the control of pressure, and the design determines that feed pressure is≤0.8Mpa, air-dry pressure be≤
0.8Mpa, in addition in air drying process, the former does not illustrate that the control process of pressure, the design are required when air-dried, first had to
It controls and air-dries pressure difference, variation of the pressure difference from 0 to 0.8Mpa, this needs the regular hour, because if allowing pressure difference to reach at the very start
It to maximum, is easy to blow filter plate, filter cloth bad, separately filter cake can also be blown logical from a certain position, cause air duct short-circuit, it can not be in filter cake
Interior formation equilibrium, uniform air duct lose air-dried effect or reduce air-dried effect.
5, the former does not illustrate how the gas of gas vent discharge is handled, and the design considers the vapour being discharged in air drying process
Also contain water or other liquid containing air in body, some superfine material particles will if be discharged in air
It pollutes, is separated so being provided with steam-water separator, make final water or other liquid, gas, fines with normal
The state of pressure exists, and water or other liquid are returned in system and is collected, and clean air is discharged in atmosphere.
6, the former does not illustrate that feed inlet is side or two sides, because this is related to equipment disposal ability, the design is bright
Appropriate filter area is less than 150m2When, it is side pan feeding, if it is larger than or equal to 150m2When, it feeds for bilateral, can subtract in this way
Few pan feeding time, improve equipment work efficiency.
7, the former does not illustrate pressure maintaining period, and only according to determining whether to complete charging either with or without draining, the design set
It is equipped with pressure maintaining link, when material is during into full material chamber, resistance is increasing, if there is no pressure maintaining link, the pressure of pan feeding
Power will increase quickly, and the pressure of such pan feeding is possible to that the pressure that filter plate is born can be greater than, and damage, it is also possible to right
It is damaged with material pump, valve, sensor or pipeline.
8, the wind of the design is to enter to carry out air-dried from both ends, can improve air-dried efficiency in this way, if from one end into
Enter, then during doing, dry wind can export close place from distance first and flow through, and the flow by the pressure of most distal section will become
It is small, that is, the air-dried effect of filter cake of farthest side will be poor, so the design regardless of pan feeding, is both ends air inlet, and
And utilize the variation of process control pressure difference, it is ensured that the wind flow of all filter room pressures is balanced, guarantees to air-dry effect, the former does not have
