Background technology
Asphalt carbon fiber is a kind of novel charcoal material, and high softening point bitumen is one of important source material of pitch based carbon fiber, is characterized in that softening point is high, viscosity is large, impurity is not of uniform size.Impurity in high softening point bitumen directly affects production and the quality of Carbon fibe, and how stablizing the effective impurity filtered in high softening point bitumen is that the important of development is at present dealt with problems.
When current high softening point bitumen hot melt filters, often there will be filter net jam, the distortion of hypertonia filter screen or break through, the phenomenon such as filtering accuracy is low, frequent replacing filter screen.As asphalt filters such as domestic patents 200920318385.0,200920034884.7, its structure is comparatively simple, main filtration mode is directly filtered by filter cylinder small-bore or the filter screen that is wrapped in filter cylinder outside, because one deck filter screen can only be used or directly use filter cylinder aperture to filter, its precision of filtering is very low, generally can only carry out the coarse filtration of pitch, its filter effect cannot meet the requirement preparing asphalt base charcoal materials; When filtering cold primer-oil, because asphalt viscosity is excessive, so very high pressure can be produced to reach pitch high-precision filtration effect in filtration, the stressed main body of above-mentioned several filter is filter cylinder, filter cylinder is cylindric, bears pressure not high, and the pressure produced when filtering all is born by filter screen or filter cylinder, then occurring that under high pressure material is lower is yielding, affects filter effect; The scavenge port of the inner all neither one impurity of a lot of asphalt filter at present, the impurity filtered gets lodged on filter screen and cannot discharge, cause filtration time low, particularly filtering accuracy requires the required precision of high asphalt base charcoal materials, often because of filter net jam, hypertonia and frequently change filter screen in filtration, very large impact is brought on production.
Summary of the invention
The object of high softening point bitumen hot melt filter of the present utility model be to provide a kind of structure simple, bear pressure large, in the filter of same homalographic, impurity can be discharged in the filter process of high softening point bitumen, strengthen the time of filtration, the better high-melting-point asphalt solution strainer of filter effect.
To achieve these goals, the utility model provides a kind of high softening point bitumen hot melt filter, and inlet seal flange and exit seal flange are fixed on the both sides of filter cylinder, are provided with heating jacket in the outside of filter cylinder, multistage distribution plate and screen pack is provided with in the inside of filter cylinder
Distribution plate is provided with multiple hole, so that pitch passes through along pitch direction of motion partition; Distribution plate has some partition planes by high softening point bitumen hole and vertical direction forms inclination angle; Be provided with distribution plate cavity by the port of export in high softening point bitumen hole, distribution plate cavity top is provided with distribution plate scavenge port;
Along the direction of motion of high softening point bitumen, the distribution order number of next stage screen pack is more than the distribution order number of upper level screen pack;
Also ultrasonic oscillator is provided with in the outside of filter cylinder;
Distribution plate scavenge port connects with impurity excretory duct, is provided with impurity bleed valve at the outlet end of impurity excretory duct.
In filter running, high softening point bitumen impurity mainly rests on the upper end of distribution plate cavity, the impurity making to be blocked in screen pack by ultrasonic oscillator more progressively on move, last impurity enters impurity excretory duct from distribution plate scavenge port, realizes the growth of filtration time.
High softening point bitumen described in the utility model, refers to the pitch of softening point more than 200 DEG C.
The utility model has following beneficial effect: decrease screen pack clogging, extends the service time of filter, decreases number of times and the time of process screen pack, improves operating efficiency, decrease operating cost.

Detailed description of the invention
Below in conjunction with embodiment accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, be a kind of high softening point bitumen hot melt filter embodiment.
Inlet seal flange 1 and exit seal flange 2 are fixed on the both sides of filter cylinder 3, heating jacket 4 is provided with in the outside of filter cylinder 3, multistage distribution plate and screen pack is provided with in the inside of filter cylinder 3, multistage distribution plate and screen pack are made up of entrance distribution plate 5, single filter net 6, one-level distribution plate 7, cascade filtration net 8, secondary distribution plate 9, three-stage filtration net 10, three grades of distribution plates 11, level Four screen pack 12, level Four distribution plate 13, Pyatyi screen pack 14, Pyatyi distribution plates 15, form Pyatyi and filter.Cold primer-oil enters in filter cylinder 3 by inlet seal flange 1, and the cold primer-oil of high pressure is when by single filter net 6, and the pressure produced in filtration is born by one-level distribution plate 7, and single filter net 6 can not be broken through because of high pressure, the like.Filter pressure is under the pressure of 3.0Mpa by experiment, and single filter net 6 can not break.
Ultrasonic oscillator 19 is also provided with in the outside of filter cylinder 3;
Distribution plate scavenge port 18 connects with impurity excretory duct 16, is provided with impurity bleed valve 17 at the outlet end of impurity excretory duct 16.
Along the direction of motion of high softening point bitumen, the distribution order number of next stage screen pack filter opening is more than the distribution order number of upper level screen pack filter opening.
In production carbon fiber precursors way, have impurity much not of uniform size in cold primer-oil, we adopt single filter net 6 filtering accuracy to be 20 μm; Cascade filtration net 8 filtering accuracy is 15 μm; Three-stage filtration net 10 filtering accuracy is 10 μm; Level Four filter screen filtration precision 12 is 5 μm; Pyatyi screen pack 14 filtering accuracy is 3 μm.Cold primer-oil is when by single filter net 6, filter the impurity of diameter more than 20 μm, cascade filtration net 8 has filtered diameter at the impurity of about 15 μm, be filled into Pyatyi successively when filtering 14, filter the impurity of diameter more than 3 μm, make the large impurity of diameter in cold primer-oil can not block screen pack below, make the impurity in cold primer-oil reach the required precision of asphalt base charcoal materials and reduce the load of each screen pack, add the filtration time of cold primer-oil and the precision of filtration greatly.
The utility model is used to carry out the filtration of high softening point bitumen hot melt, impurity in hot-melt asphalt is because of entrance distribution plate 5, one-level distribution plate 7, secondary distribution plate 9, three grades of distribution plates 11, level Four distribution plate 13, the angle of inclination of Pyatyi distribution plate 15, impurity is had and certain upwards gathers trend, afterwards by the vibrations of ultrasonic oscillator 19 by the impurity in hot-melt asphalt be blocked in single filter net 6, cascade filtration net 8, three-stage filtration net 10, level Four screen pack 12, the impurity on Pyatyi screen pack 14 surface loosens and automatically upwards gathers, when filter pressure goes up to 2Mpa, open impurity bleed valve 17 impurity being collected at distribution plate upper end is discharged along impurity excretory duct 16, only has a small amount of impurities left in filter, impurity bleed valve 17 is closed after impurity excretion certain hour, now the pressure of filter drops to below 1.2Mpa, substantially increase filtration time, decrease the time of dismounting and replacing filter screen, improve production efficiency.
