4 Claims. 1
This invention relates to sampling devices and is particularly concerned with a device adapted to take samples of a fluid medium, such as of vapor or gas, or of suspended materials within a gasous or vaporous fluid medium. Such suspended materials may be dust particles, pigments, fibers, grains, sand, gravel, and other particulate materials, such as wood flour, sawdust or other fillers used in the plastic industries. Thus, the sampling device is applicable to numerous industries including textile industry for sampling fibers, the food industry for sampling cereal grains, the plastics industries for sampling fillers, and what not.
It is a particular object of the invention to provide an apparatus for taking samples automatically at definite intervals so as to provide representative selections of the material. A further object of the invention is to provide a sampling device which is capable of withdrawing automatically or withdrawing at intervals representative samples from a flowing stream of the fluid or fluid suspension. Other objects and advan- .tages of the invention will be apparent from the drawing and the description thereof hereinafter.
In the drawing, illustrative of the invention Figure 1 is a plan view, in somewhat diagrammatic form showing one embodiment of the appilcation as applied to the sampling of a fiber suspension,
Figure 2 is an elevation of the embodiment of Figure 1,
Figure 3 is an enlarged sectional view, on line III-411 of Figure 1, of the sampling device itself,
Figure 4 is a diagrammatic View in elevation of a modified arrangement, and
Figure 5 is a diagrammatic view in elevation of a second modified arrangement.
Figures 1 to 3 show the sampling device installed upon a fiber-conveying system such as is used in the textile industry for taking fibers from a dryer and delivering them to a packaging system, such as a baling press. Such fibers may be natural or artificial, such as cotton, wool, silk, rayon, nylon, saran, etc. In the installation shown, the fibers proceed through the discharge duct 3 coming from the dryer or other source of fiber to a rotary condenser 4 from which the fibers are discharged downwardly into the hopper 5 of a baling press or other receiving system. The duct 3 may flare out as at 3a as it approaches the condenser 4. To effect deposition of the fibers upon the condenser, suction is applied to a duct 6 which communicates by means of ducts l with the end chambers 8 of a conventional rotary condenser. In such a condenser, the suction in the end chambers exerts its influence upon the interior of the perforated drum of the condenser along the portion of its peripher upon which the fiber-conveying stream firstmakes contact. Suitable radial partitions within the perforated drum and fixed diaphragms at the ends of the drum are provided upon conventional condensers for this purpose and will not be described.
In order to take a representative sample from the fiber suspension as it proceeds to the condenser, a branch duct 9 is connected with duct 3 and preferably extends away from duct 3 in the direction of flow of the fibers therethrough, such direction being at an angle as shown. The duct 9 opens at l0 into the cylindrical housing ll of the sampling device. The sampling device is preferably disposed in a vertical disposition though it may be inclined thereto if desired and the opening [0 is generally spaced a substantial distance from the bottom of the cylinder H. The lower end of the cylinder H is closed by a readily removable cap 12 and the upper end is similarly provided with a cap l3. A duct I4 is connected to the suction duct 6 and to the cylindrical housing II at a point between the connection ID and the cap [3.
Within the housing ll there is provided a plunger or piston 16 which has a tight sliding fit within the inside wall of the housing H. The head or base of the piston is constituted of, or provided with an insert constituted of, a fluidpervious separator, such as a screen or filter IS. The separator i5 is preferably spaced back of the outer edge of a tapering annular rim ll projecting from the head and provided for the purpose of pushing downward any fibers that may be partway within the housing II and partway within duct 9 as the edge of rim ll passes over the opening Iii. The skirt of plunger I6 is provided with a slot [ta which registers with the opening of duct l4 into cylinderl 1.
Means is provided for reciprocating the plunger l6 within the cylinder II and such means may advantageously take the form of the hydraulic or pneumatic cylinder l8 suspended by means of a cross pin or rod W at the upper end of the cylinder H. A piston 20' within cylinder I8 is connected by a rod 2| with the head of the plunger such as by the nut 2|. Pipes 22 and 23 respectively are provided to introduce air, liquid or the like in the opposite ends of the cylinder 18 to reciprocate the piston 20 and the plunger 16 one
