Description
Technical field
The present invention relates to a kind of filter device, more particularly to the filter disk of a kind of polyester fondant.
Background technology
Polyester film production line is needed using the impurity in fondant filter melt filtration, and the melt by filtering enters drawing
Film produces.The quality of fondant filter filter effect directly affects normal production and its interior quality of film.
Fondant filter is mainly made of three parts, respectively filter housing, disk and filter core pipe.Outside filter
Shell is a cavity body structure, and filter disk is sleeved on by certain amount, stacked structure in filter core pipe, equipped with close between disk
Gasket, it is closed to be positioned over inside cavity, it is combined by bolt and sealing ring fastening, there is melt to enter filter below filter
Entrance channel, melt is after the filtering of stacked disk, into filter core pipe intermediate flow channel, using melt outlet above filter
Runner outflow filter.Polyester fondant is a kind of highly viscous fluid liquid, and temperature can reach 275 DEG C or so, to reach
Good filter effect, runner is unobstructed particularly important, is high to the requirement of filter disk.
Existing PALL filters disk is that disk is formed with holder part for a conjoined structure, sees Fig. 1, Fig. 3, disc surface
The supporting rack of welding and center connection ring are almost the same in dimensional thickness, and connection ring central area area is smaller.This
After being assembled by stacking under situation, i.e. there are dead angle, melt is long in this region meeting residence time and produces for connection ring central area
Raw degradation.In this way, rupture of membranes on the one hand can be caused, rate of film build is low, influences normally to produce and causes to waste, on the other hand will produce fisheye
Influence the quality of film and the service life of filter.
Invention content
The object of the present invention is to provide a kind of filter disks to connect ring diameter by expanded stent, and supporting rack is connected
The ratio disk supporting rack thickness that ring material thickness is done is small, makes the supporting rack between disk and there are certain thickness between connection ring
Difference, to eliminate dead zone, such melt this region can be much smoother flow without because the residence time is long, generating
Degradation, efficiently solving original PALL disks, there are melt retention problems.
A kind of filter disk, including disk body and disk shell；The disk body include strainer, disk inner ring and
Disk outer shroud；The strainer is set to the upper and lower surface between disk inner and outer rings；The disk shell include disk supporting rack and
Supporting rack connection ring, the disk supporting rack is by the disk support bar group of certain amount at disk supporting rod one end and dish
The upper surface of piece outer shroud connects, and the other end is connect with supporting rack connection ring, and is evenly distributed on disk filter upper surface, will be filtered
Device upper surface is divided into sector region；The ring wall of the disk inner ring is equipped with aperture；
Support frame as described above connection ring shares the same center of circle with disk inner ring, and the diameter of supporting rack connection ring is than disk inner ring
The big 40-60mm of diameter；
The main body of the disk supporting rod is rectangular-shape, and the top section being connect with supporting rack connection ring is right angle
Trapezoidal shape, the bottom surface in right-angled trapezium shape are connect with the main body of disk supporting rod, the upper bottom surface in right-angled trapezium shape and support
The outer wall of frame connection ring is connected；Vertical side in the right-angled trapezium shape of top is close to the face of upper filter screen；
The radial width of upper bottom surface is equal with the wall thickness of supporting rack connection ring in the top right-angled trapezium shape, and top is straight
The radial width of bottom surface is bigger 1-2mm than the radial width of upper bottom surface in the trapezoidal shape of angle.
A kind of filter disk as described above, the disk supporting rod number are 8-12.
A kind of filter disk as described above, the disk supporting rod connect end part bending with disk outer shroud, curved
Roll over the outer wall shape Corresponding matching of partial shape and disk outer shroud.
The filtering accuracy of a kind of filter disk as described above, the strainer is 10 μm~100 μm.
The material of a kind of filter disk as described above, support frame as described above connection ring is that polishing silver-plated process is done on surface
Stainless steel.
The principle of the present invention is：
Polyester fondant is a kind of highly viscous fluid liquid, and temperature can reach 275 DEG C or so, to the filtering reached
Effect, runner is unobstructed particularly important, is high to the requirement of filter disk.When filtering, filter disk by certain amount,
Stacked structure is sleeved in filter core pipe, between disk be equipped with gasket seal, it is closed to be positioned over inside cavity, by bolt with it is close
Seal ring fastening combines, and melt is after the filtering of stacked disk, by the aperture in disk inner ring, into filter core pipe intermediate flow
Road, but original PALL filters disk it is stacked be mounted on filter core pipe on when, due to disc surface welding supporting rack
Connecting rod and disk inner ring in connection ring is almost the same in dimensional thickness, and central area area between the two is very
It is small, when filter disk is according to stacking assembling mode assembling, after being compressed using normal pressure to disk, center ring region between the two
Domain will become closed dead zone, be easily detained when melt is into the region at this time and generate degradation, and it is unfavorable to be generated to product quality
It influences, and the filter disk of the present invention, since the thickness of disk supporting rack is bigger 1-2mm than the thickness of supporting rack connection ring, and
The diameter of supporting rack connection ring is bigger 40-60mm than the diameter of disk inner ring；Center between supporting rack connection ring and disk inner ring
Region area is larger, and melt is easy to flow in this region, dead zone is not present, runner is unobstructed, efficiently solves original
There are melt retention problems for PALL disks, and product quality is effectively ensured, saves production cost.
Advantageous effect：
The object of the present invention is to provide a kind of filter disks to effectively eliminate original PALL disks dead zone, and melt is made to exist
This region can be flowed much smootherly without because the residence time is long, generating degradation, efficiently solving original PALL disks and deposit
In melt retention problems.Both having extended the service life of filter reduces production cost；Polyester film life is also improved simultaneously
Produce stability and its quality of inherence.
