Definitions
- This invention relates to filters and more particularly to candle type filters for use in artificial yarn producing apparatus.
- a solution or melt of filament-forming material is pumped through a spinning jet containing one or more orifices into a setting medium.
- the diameter of the spinning orifices will vary depending upon the size of the filaments desired, but the orifices may be of a diameter as low as 0.05 to 0.1 millimeter or even less. If there are any solid impurities in the spinning solution or melt, they will tend to lodge in and clog one or more of the orifices which will result in the production of a defective yarn. It is, therefore, necessary to filter the spinning solution or melt several times to remove any solid impurities therefrom.
- a final filtration of the solution or melt is conducted by means of a candle filter mounted in the line leading from the spinning pump to the spinning jet.
- a yarn can be produced that has uniformity in both tensile strength and dyeing characteristics while the danger of breakage during the spinning is reduced.
- An object of the invention is to provide a novel and improved candle filter.
- a further object is to provide a candle filter wherein traps or stagnant zones are eliminated.
- the filter in brief comprises a fluid-tight housing which surrounds a filter core whereby an annular space 01' chamber is formed between the housing and core.
- the core has a plurality of grooves formed on and around its periphery longitudinally of the core.
- a filtering material is secured about the core so that all of the fluid to be filtered must pass through this material.
- Passages or conduits for the fluid preferably extend from one end of each groove to an axial bore in the filter core. It is essential to the construction that each groove extends to its passage or conduit and not beyond the passage.
- a ring or sleeve may be provided about the periphery of the core at the end of the core secured to the housing.
- the ring is of such shape that it forms an abutment or dam in the chamber between the core and the housing which extends from the openings of the passages or conduits at the ends of the grooves to the end of the core where the core is secured to the housing.
- the liquid to be filtered may be introduced through the axial bore of the core or to the annular space between the filter core and the housing.
- the fluid if introduced into the annular space between the core and the housing, passes through a supply opening in the housing into the annular space, through the filter material, such as cloth, along the grooves, into the passages or conduits at the ends of the grooves and into the bore of the filter core.
- the solution then travels through the bore and out through a discharge conduit. If the solution is introduced into the axial bore, the path of travel indicated above is reversed.
- the filter will be described as a cylindrical filter it is not intended to be limitative.
- the invention is applicable to other shapes and types of construction such as square, hexagonal, or cylindrical cores with various shaped housings.
- the conduits leading into the housing may be in aligned as well as parallel or angular relationship to each other and the grooves on the surface of the core may extend axially, spirally, or both.
- Figure l is a side elevation of one embodiment of the candle filter partly in section
- Figure 2 is a sectional view of the core of the filter of Figure 1 taken on line IIII,
- Figure 3 is a developed view of the ring shown in Figures 1 and 2,
- Figure 4 is a side elevation partially sectioned of a modification
- Figure 5 is a side elevation of a further modification
- Figure 6 is a side elevational partially sectioned of still a further modification.
- the fluid-tight housing 1 forms an annular space or chamber 2 with the filter core 3 that completely surrounds the filter core 3.
- a discharge or entrance pipe 4 At one end of the housing 1, there is a discharge or entrance pipe 4 while at the opposite end there is a plug 5 for supporting the core 3 in position within the housing 1 and for sealing that end of the housing.
- the plug 5 also supports an entrance or discharge pipe 6 for the fluid to be filtered.
- the core 3 is secured to the plug 5 in any suitable manner, preferably with a screw-type fitting 7.
- the core 3 is an elongated member provided with an axial inner bore 8. Longitudinal grooves 9, 9 in the core surface are of various lengths and extend longitudinally of the core around or about its periphery.
- a filtering material 10 comprising one or more layers or sleeves of closely woven fabric or the like.
- the filtering material 10 is secured in place by clamps or cords 11 that clasp the fabric to circular grooves 12 about the periphery of the core 3.
- the circular grooves 12 are disposed at each end of the core 3.
- Passages or conduits 13, 13 extend inwardly at right angles to the axis of the core from one extreme end of each longitudinal groove 9 on the surface of the core 3 to the axial bore 8.
- the conduits 13, 13 thereby connect with the bore in an offset or staggered relationship which arrangement provides excellent support for the core to resist the pressure applied thereupon by the fluid to be filtered.
- a ring or sleeve 14 may be fitted about the periphery of the core at the end of the core 3 that is secured to the housing 1.
- the ring 14 occupies the space in the annular chamber 2 between the core 3 and the housing 1 and extends from the supported end of the core 3 to the edge of the outer ends or termini 17, 17 of the passageways 13, 13.
- the outer ends or termini 17, 17 of the passageways 13, 13 are staggered axially of the core 3 in view of the varying lengths of the grooves and therefore the end of the ring 14 extending away from the supported end of the core is correspondingly stepped in shape as shown in Figure 3 wherein the difierentlevel stepsof theflsleeve 14 are identified .asA,
- the sleeve 14 is keyed by its key 15 to a core keyway 15' whereby the ,proper relationship is assured between the steps of the sleeve 14 and the outer ends or termini 17, 17 of thepassages or conduits 13, 13 upon assembling the filt .inone method of using this filter, a fluid passes from conduit 6 within the plug 5 into thebore 8 of thecore '3, through the passages 13, I13, and then flows alongthe grooves .9 and out through the filter material "210 and is t'finally discharged through conduit 4.
- FIG. 4 Another modification of this invention is shown in Figure 4 where passages or conduits 16 connecting the longitudinal grooves 9 with the bore 8 in the core 3 do not extend inwardly at right angles to the axis of the bore as with the embodiment described above but rather slant toward the end of the bore in communication with the conduit 6 as they extend inwardly to connect with the bore.
- a ring or sleeve 18 may be fitted about the periphery of the core 3 at the end of the core that is secured to the housing.
- the sleeve is of such a shape that it occupies the annular space or chamber between the core and the housing and extends from the outer ends or termini -17 of the passages 16, 16 in the grooves 9 to the supported end of the core.
- the sleeve has an inwardly extending radial flange 18a that extends between the core 3 and the plug 5 to enable the sleeve to be secured in place by screwing the core into the plug.
- the longitudinal grooves 9, 9 are all of the same length so that outer ends or termini 17 of the passages 16, 16 in the grooves are all in a common plane transverse or perpendicular to the core.
- This modification has the advantage that the fluid has more of a tendency to flow along the grooves and therefore more uniformly through the filter material than when the passages are at right angles to the grooves.
- Figure 5 shows a further modification of the filter.
- the longitudinal grooves 19 are not continued along the Whole length of the core but are divided so that they are in the form of two or more longitudinal grooves in linear relationship to each other in place of the one longitudinal groove.
- Passages or conduits 20 extend in slanting fashion as in Figure 4 from the bore to the extreme end of each groove.
- the passages could, of course, extend at right angles to the bore. In this system a greater amount of fluid can be passed through the core over a more uniform area than when single longitudinal grooves are used.
- Figure 6 shows a further modification which is similar to that modification shown in Figure 4.
- the grooves 9, 9 are of different lengths as with the embodiment of Figure 1.
- the passageways or conduits 16, 16 which connect the longitudinal grooves 9, 9 with the bore 8 extend angularly or on a slant from the ends of the grooves toward the end of. the bore in communication with the conduit 6 as they extend inwardly to connect with the bore.
- the outer ends or termini 17, 17 of the conduits 16, 16 are in staggered relationship axially or" the core 3 since the grooves 9, 9 are of different lengths, additional support is thereby provided for the core 3.
- a stepped sleeve 14 having different level steps as used and described with the embodiment of Figure 1 is used with the structure of Figure 6. In every other respect, the modification shown in Figure 6 corresponds to that of Figure 4.
