Description
Technical field
The utility model relates to fondant filter, particularly a kind of melt filtration core being used for filtering chemical fibre raw material impurity.
Background technology
Fondant filter is widely used in spinning production line, its main purpose is organic melt, solid impurity such as charing particle and metal oxide etc. in removing chemical fibre raw material, for follow-up spinning process provides qualified raw material to ensure, so that melt can become silk by spinneret orifice and not block smoothly, ensure the normal production of spinning process.The environment for use of fondant filter is high temperature and high pressure environment, and therefore filter, particularly filtration core are parts very crucial during spinning is produced.
See Fig. 1, existing filtration core is cylindrical, filter course A1 is fixed between end cap B1 and B2 at upper and lower two ends, the passage formed inside filter course A1 is melt flow channel A2, melt flows into from one end of melt flow channel, under High Pressure, melt four loose to flow in external tank body after filtering layer A1 filters.But, the flow velocity of melt in melt flow channel can slow down gradually, make each section of pressurized inequality of filter course A1, the phenomenon causing filter course A1 easily to produce the phenomenon of falling pleat and radial direction to heave, cause the strainability of filter core and service life to be reduced, therefore need the melt filtration core of the balanced melt flow of a kind of energy of design badly.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is the melt filtration core providing the balanced melt flow of a kind of energy, to realize the object improving strainability and increase the service life.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of melt filtration core, comprise filter course, upper end cover and bottom end cover, described filter course is fixed between described upper end cover and bottom end cover, described upper end cover is provided with fluid intake, the passage formed inside described filter course is melt flow channel, be provided with interior pipe in described melt flow channel, the outer wall of described interior pipe is connected with the inner side of described filter course, and the inner chamber of described interior pipe is communicated with described fluid intake; The tube wall of described interior pipe is evenly equipped with several through hole, and the diameter of described through hole is 3-5mm.
Preferably, described interior Guan Youyi band steel forms through spiral welded, and the weld width on described interior pipe is 7-8mm, and the helical angle of described weld seam is 40-50 °.
Preferably, the outer wall of described upper end cover is provided with thread.
Preferably, the arranged outside of described filter course has metal fixed network, and the two ends of described metal fixed network are connected with described upper end cover and bottom end cover respectively.
Preferably, the two ends of described filter course and the junction of described upper end cover and bottom end cover are provided with T-shaped sealing ring.
Pass through technique scheme, the melt filtration core that the utility model provides, arranges in the inner side of filter course in one and manages, and the uniform through hole in utilizing on pipe carries out equilibrium to the flow velocity of melt, eliminate the phenomenon of pressure inequality, effectively raise strainability and extend service life of filtration core.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment and technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment and description of the prior art below.
Fig. 1 is the schematic diagram of melt filtration core in prior art;
Fig. 2 is the generalized section of a kind of melt filtration core disclosed in the utility model embodiment;
Fig. 3 is the enlarged diagram at C place in Fig. 2;
Fig. 4 is the generalized section of the interior pipe disclosed in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figures 2 and 3, a kind of melt filtration core, comprise filter course 11, upper end cover 12 and bottom end cover 13, filter course 11 is fixed between upper end cover 12 and bottom end cover 13, upper end cover 12 is provided with fluid intake, and the passage formed inside filter course 11 is melt flow channel, is provided with interior pipe 14 in melt flow channel, the outer wall of interior pipe 14 is connected with the inner side of filter course 11, and the inner chamber of interior pipe 14 is communicated with fluid intake; The tube wall of interior pipe 14 is evenly equipped with several through hole 15, and the diameter of through hole 15 is 3.2mm.Melt is from fluid intake flows into pipe, and under High Pressure, melt enters filter course from through hole 15, and melt four loosely to flow in external tank body after filtering layer filters.Uniform through hole on interior pipe carries out equilibrium to the flow velocity of melt, eliminates the phenomenon of pressure inequality, effectively raises strainability and extends service life of filtration core.And the setting of interior pipe can also play support fixation to filter course, adds the intensity of filter course.
See Fig. 4, interior pipe 14 is formed through spiral welded by a band steel, and weld seam 16 width on interior pipe 14 is 7.3mm, and the helical angle of weld seam 16 is 45 °, and therefore the combined stress at spiral weld 16 place is about 50% of ERW principal stress.Under identical operating pressure, the spiral welded pipe of same caliber can reduce than ERW wall thickness.
The outer wall of upper end cover 12 is provided with thread 17, for being paid in fondant filter by whole filtration core lock.
The arranged outside of filter course 11 has metal fixed network 18, and the two ends of metal fixed network 18 are connected with upper end cover 12 and bottom end cover 13 respectively.Hole on metal fixed network 18 is the square hole of 8*8, metal fixed network 18 the intensity that can increase filter course 11 is set.
The two ends of filter course 11 and the junction of upper end cover 12 and bottom end cover 13 are provided with T-shaped sealing ring 19.
In sum, the features such as melt filtration core has firmly, strainability is good, physical life is long that the utility model provides.
